Increasing confidence in vergence as a cue to distance. (1/254)

Multiple cues contribute to the visual perception of an object's distance from the observer. The manner in which the nervous system combines these various cues is of considerable interest. Although it is accepted that image cues play a significant role in distance perception, controversy exists regarding the use of kinaesthetic information about the eyes' state of convergence. We used a perturbation technique to explore the contribution of vergence to visually based distance estimates as a function of both fixation distance and the availability of retinal information. Our results show that the nervous system increases the weighting given to vergence as (i) fixation distance becomes closer; and (ii) the available retinal image cues decrease. We also identified the presence of a strong contraction bias when distance cues were studied in isolation, but we argue that such biases do not suggest that vergence provides an ineffectual signal for near-space perception.  (+info)

Effects of viewing distance on the responses of horizontal canal-related secondary vestibular neurons during angular head rotation. (2/254)

Effects of viewing distance on the responses of horizontal canal-related secondary vestibular neurons during angular head rotation. The eye movements generated by the horizontal canal-related angular vestibuloocular reflex (AVOR) depend on the distance of the image from the head and the axis of head rotation. The effects of viewing distance on the responses of 105 horizontal canal-related central vestibular neurons were examined in two squirrel monkeys that were trained to fixate small, earth-stationary targets at different distances (10 and 150 cm) from their eyes. The majority of these cells (77/105) were identified as secondary vestibular neurons by synaptic activation following electrical stimulation of the vestibular nerve. All of the viewing distance-sensitive units were also sensitive to eye movements in the absence of head movements. Some classes of eye movement-related vestibular units were more sensitive to viewing distance than others. For example, the average increase in rotational gain (discharge rate/head velocity) of position-vestibular-pause units was 20%, whereas the gain increase of eye-head-velocity units was 44%. The concomitant change in gain of the AVOR was 11%. Near viewing responses of units phase lagged the responses they generated during far target viewing by 6-25 degrees. A similar phase lag was not observed in either the near AVOR eye movements or in the firing behavior of burst-position units in the vestibular nuclei whose firing behavior was only related to eye movements. The viewing distance-related increase in the evoked eye movements and in the rotational gain of all unit classes declined progressively as stimulus frequency increased from 0.7 to 4.0 Hz. When monkeys canceled their VOR by fixating head-stationary targets, the responses recorded during near and far target viewing were comparable. However, the viewing distance-related response changes exhibited by central units were not directly attributable to the eye movement signals they generated. Subtraction of static eye position signals reduced, but did not abolish viewing distance gain changes in most units. Smooth pursuit eye velocity sensitivity and viewing distance sensitivity were not well correlated. We conclude that the central premotor pathways that mediate the AVOR also mediate viewing distance-related changes in the reflex. Because irregular vestibular nerve afferents are necessary for viewing distance-related gain changes in the AVOR, we suggest that a central estimate of viewing distance is used to parametrically modify vestibular afferent inputs to secondary vestibuloocular reflex pathways.  (+info)

Effects of viewing distance on the responses of vestibular neurons to combined angular and linear vestibular stimulation. (3/254)

Effects of viewing distance on the responses of vestibular neurons to combined angular and linear vestibular stimulation. The firing behavior of 59 horizontal canal-related secondary vestibular neurons was studied in alert squirrel monkeys during the combined angular and linear vestibuloocular reflex (CVOR). The CVOR was evoked by positioning the animal's head 20 cm in front of, or behind, the axis of rotation during whole body rotation (0.7, 1.9, and 4.0 Hz). The effect of viewing distance was studied by having the monkeys fixate small targets that were either near (10 cm) or far (1.3-1.7 m) from the eyes. Most units (50/59) were sensitive to eye movements and were monosynaptically activated after electrical stimulation of the vestibular nerve (51/56 tested). The responses of eye movement-related units were significantly affected by viewing distance. The viewing distance-related change in response gain of many eye-head-velocity and burst-position units was comparable with the change in eye movement gain. On the other hand, position-vestibular-pause units were approximately half as sensitive to changes in viewing distance as were eye movements. The sensitivity of units to the linear vestibuloocular reflex (LVOR) was estimated by subtraction of angular vestibuloocular reflex (AVOR)-related responses recorded with the head in the center of the axis of rotation from CVOR responses. During far target viewing, unit sensitivity to linear translation was small, but during near target viewing the firing rate of many units was strongly modulated. The LVOR responses and viewing distance-related LVOR responses of most units were nearly in phase with linear head velocity. The signals generated by secondary vestibular units during voluntary cancellation of the AVOR and CVOR were comparable. However, unit sensitivity to linear translation and angular rotation were not well correlated either during far or near target viewing. Unit LVOR responses were also not well correlated with their sensitivity to smooth pursuit eye movements or their sensitivity to viewing distance during the AVOR. On the other hand there was a significant correlation between static eye position sensitivity and sensitivity to viewing distance. We conclude that secondary horizontal canal-related vestibuloocular pathways are an important part of the premotor neural substrate that produces the LVOR. The otolith sensory signals that appear on these pathways have been spatially and temporally transformed to match the angular eye movement commands required to stabilize images at different distances. We suggest that this transformation may be performed by the circuits related to temporal integration of the LVOR.  (+info)

Long range interactions between oriented texture elements. (4/254)

Long range interactions between texture elements (short, oriented line segments) were examined. Specifically, we studied the influence of a background array of texture elements on the detectability of a target element (separated from the background by an intermediate textured region) using textures like those of Caputo (Vis. Res. 1996, 36, 2815-2826). We found that, in general, when the background elements were oriented orthogonally to the target element, detection of the target element was better than when the background elements had the same orientation as the target element. We discuss these interactions in terms of inhibitory and excitatory connections between orientation and spatial frequency selective linear filters (e.g. filters which mimic V1 simple cells) which would respond to the individual texture elements.  (+info)

Perceived distance, shape and size. (5/254)

If distance, shape and size are judged independently from the retinal and extra-retinal information at hand, different kinds of information can be expected to dominate each judgement, so that errors in one judgement need not be consistent with errors in other judgements. In order to evaluate how independent these three judgments are, we examined how adding information that improves one judgement influences the others. Subjects adjusted the size and the global shape of a computer-simulated ellipsoid to match a tennis ball. They then indicated manually where they judged the simulated ball to be. Adding information about distance improved the three judgements in a consistent manner, demonstrating that a considerable part of the errors in all three judgements were due to misestimating the distance. Adding information about shape that is independent of distance improved subjects' judgements of shape, but did not influence the set size or the manually indicated distance. Thus, subjects ignored conflicts between the cues when judging the shape, rather than using the conflicts to improve their estimate of the ellipsoid's distance. We conclude that the judgements are quite independent, in the sense that no attempt is made to attain consistency, but that they do rely on some common measures, such as that of distance.  (+info)

Driver distance from the steering wheel: perception and objective measurement. (6/254)

OBJECTIVES: This study assessed the accuracy of driver perceptions of the distance between the driver's nose and the steering wheel of the vehicle as a factor in considering driver disconnection of an airbag contained in the steering wheel for preventing injury to the driver in an accident. METHODS: A cross-sectional survey of 1000 drivers was done to obtain perceived and objective measurements of the distance between the driver's nose and the steering wheel of the vehicle. RESULTS: Of 234 drivers who believed that they sat within 12 inches of the steering wheel, only 8 (3%) actually did so, whereas of 658 drivers who did not believe that they sat within 12 inches of the wheel, 14 (2%) did so. Shorter drivers were more likely than taller ones to both underestimate and overestimate their seating distance. CONCLUSIONS: Considerable misperception of drivers' distance from the wheel indicates that drivers should objectively measure this distance.  (+info)

Explaining the moon illusion. (7/254)

An old explanation of the moon illusion holds that various cues place the horizon moon at an effectively greater distance than the elevated moon. Although both moons have the same angular size, the horizon moon must be perceived as larger. More recent explanations hold that differences in accommodation or other factors cause the elevated moon to appear smaller. As a result of this illusory difference in size, the elevated moon appears to be more distant than the horizon moon. These two explanations, both based on the geometry of stereopsis, lead to two diametrically opposed hypotheses. That is, a depth interval at a long distance is associated with a smaller binocular disparity, whereas an equal depth interval at a smaller distance is associated with a larger disparity. We conducted experiments involving artificial moons and confirmed the hypothesis that the horizon moon is at a greater perceptual distance. Moreover, when a moon of constant angular size was moved closer it was also perceived as growing smaller, which is consistent with the older explanation. Although Emmert's law does not predict the size-distance relationship over long distances, we conclude that the horizon moon is perceived as larger because the perceptual system treats it as though it is much farther away. Finally, we observe that recent explanations substitute perceived size for angular size as a cue to distance. Thus, they imply that perceptions cause perceptions.  (+info)

Honeybee navigation: nature and calibration of the "odometer". (8/254)

There are two theories about how honeybees estimate the distance to food sources. One theory proposes that distance flown is estimated in terms of energy consumption. The other suggests that the cue is visual, and is derived from the extent to which the image of the world has moved on the eye during the trip. Here the two theories are tested by observing dances of bees that have flown through a short, narrow tunnel to collect a food reward. The results show that the honeybee's "odometer" is visually driven. They also provide a calibration of the dance and the odometer in visual terms.  (+info)

When making recordings of the spoken voice, the spectrum changes with distance and direction. This paper presents the results of experiments on the audibility of these changes. Special interest has been given to listeners distance perception when comparing different spectra adjusted to the same level of loudness. One conclusion is that in some cases it is possible to detect the distance by the spectrum of the voice presented.
Some defendants replace odometers altogether, putting in a new low-mileage odometer, rather than rolling back the original odometers in vehicles. This indictment charges instances of such violations not only as odometer tampering, but also as violating provisions of the law that require specific procedures to be followed when replacing an odometer. See Count 16, charging conspiracy to commit violations of 49 U.S.C. § 32704 (in violation of 49 U.S.C. §§ 32703(4) and 32709(b)) and Counts 17 - 20 charging substantive violations of 49 U.S.C. §§ 32704(a) and 32709(b). Section 32704 requires that when an odometer is replaced, the new odometer must either (1) reflect the previous mileage, or (2) be reset to read zero - and a written notice must also be attached to the left door frame of the vehicle specifying the mileage before the odometer was replaced and the date of the replacement..

A number of listening experiments have been made to investigate how auditory distance is perceived in different rooms: an anechoic room, an IEC listening room, and a classroom. Loudspeakers were placed in the rooms playing back a voice signal. The results show that in normal rooms the sound is perceived at about the same distance as the physical distance, regardless of the playback level. In the anechoic room there is no correspondence between physical and perceived distance.

In their past research on the perception of the geometry, color, brightness and motion, Purves and his colleagues have accumulated evidence that visual processing is not the result of logical calculations about the image that falls on the retina of the eye as such. Rather, they have shown that vision is a fundamentally empirical phenomenon, in which the connections between nerve cells in the visual system evolved as a result of the success of organisms that correctly interpreted the inherently ambiguous visual world. Such ambiguity arises because the photons striking the retina do not carry any inherent information about their origins; thus the visual system must process retinal information statistically to correctly interpret a visual world that can t be known directly ...
In order to verify that the various conditions were recorded properly, several quantities such as spectrum, short-time spectrum and sound pressure level have been extracted from the audio signals. This was possible, because the digital amplitudes of the recorded signals were calibrated to a reference sound pressure level of 100 dB(SPL) which corresponds to an amplitude of 0 dBFS. Moreover, the extracted quantities facilitate conclusions with respect to dependencies between the physical properties of the sound sources and the results of the psychoacoustic experiments. The properties resp. the extracted quantities of the recordings of the passenger car and the motorcycle are compared in the following: Spectrograms: As an example, the spectrograms for the passenger car and the motorcycle for condition v = 100 kph and d = 4 m are shown in Figure 2a and Figure 2b. Here, the Doppler shift - due to the translational movement of the vehicles - can easily be observed. Moreover, the differences in the ...
Introduction. Perception development ? cross cultural studies If perceptual abilities are innate and a product of nature then we should expect similar perceptual abilities across different cultures with any differences highlighting a nurture playing a role. Turnball completed research into depth perception. He found that a pygmy tribesman who was accustomed to the dense forest struggled with long differences. When he saw a buffalo in the distance he believed them to be insects because they appeared smaller in the distance. This suggests that the depth constancy are learned and his lack of experience let to his inability to use such cues for distance perception to interpret actual size. This shows the idea that depth perception is a learned process. But, a problem with Turnball?s research is that it was a case study. ...read more. Middle.

Incorporating the fact that the senses are embodied is necessary for an organism to interpret sensory information. Before a unified perception of the world can be formed, sensory signals must be processed with reference to body representation. The various attributes of the body such as shape, proportion, posture, and movement can be both derived from the various sensory systems and can affect perception of the world (including the body itself). In this review we examine the relationships between sensory and motor information, body representations, and perceptions of the world and the body. We provide several examples of how the body affects perception (including but not limited to body perception). First we show that body orientation effects visual distance perception and object orientation. Also, visual-auditory crossmodal-correspondences depend on the orientation of the body: audio
Method and apparatus for modifying an odometer reading in a vehicle navigation system to compensate for odometer errors. A first distance measurement is obtained from the odometer, and a second distance measurement is obtained from at least one other sensor. The difference between the first and second distance measurements is determined and an adjustment amount is generated in response thereto. A modification factor is then adjusted by the adjustment amount, the modification factor being for modifying the odometer reading. The odometer reading is then modified with the modification factor. A method and apparatus for selecting a pulse rate setting in a vehicle navigation system to correspond to a pulse rate associated with the odometer are also described. A first distance measurement is obtained from the odometer and a second distance measurement is obtained from at least one other sensor. The difference between the first and second distance measurements is then determined. The pulse rate setting is

Impact of Donor-recipient Phylogenetic Distance on Bacterial Genome Transplantation.. Nucleic Acids Research. 2016 Aug 03;. External Citation. Abstract. Genome transplantation (GT) allows the installation of purified chromosomes into recipient cells, causing the resulting organisms to adopt the genotype and the phenotype conferred by the donor cells. This key process remains a bottleneck in synthetic biology, especially for genome engineering strategies of intractable and economically important microbial species. So far, this process has only been reported using two closely related bacteria, Mycoplasma mycoides subsp. capri (Mmc) and Mycoplasma capricolum subsp. capricolum (Mcap), and the main factors driving the compatibility between a donor genome and a recipient cell are poorly understood. Here, we investigated the impact of the evolutionary distance between donor and recipient ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Neurons in the visual cortex of monkeys respond selectively to the disparity between the images in the two eyes. Recent recordings have shown that some of the disparity-selective neurons in the primary visual cortex and the posterior parietal cortex are modulated by the distance of fixation. A population of such gain-modulated, disparity-selective neurons forms a set of basis functions of horizontal disparity and distance of fixation that can be used as an intermediate representation for computing egocentric distance. This distributed representation is consistent with psychophysical studies of human depth perception; in contrast, neurons explicitly tuned to distance are not consistent with how we perceive distance. In a population model that includes noise in the firing rates of neurons, the perceived distance is
A mixed 3 between (Gaze Restriction: Gaze-Fixed, Head-Fixed, and Head Free) × 2 within (viewing distance: 5 and 15 m) factor ANOVA was conducted on the individual participants gain data at each distance. The effect of Viewing Distance on angular gain differed as a function of Gaze Restriction, F(2, 32) = 7.90, p = 0.0016. This interaction is shown in Figure 5 (left). Posthoc tests, with Bonferroni correction (α = 0.017), confirmed that the gain was reliably higher when the target was nearer (i.e., 5 m), when either eye movements were allowed (Head-Fixed), t(10) = 2.92, p = 0.015, or when both head and eye movements were allowed (Head Free), t(11) = 5.05, p , 0.001; but that there was no effect of viewing distance when gaze was required to be fixed on the reference disk throughout each trial, t(11) = 1.27, p = 0.23. Recall that the reference point, to which targets were compared, was at 15 m. Because the angular gain was unaffected by viewing distance when gaze refixation on the targets was ...

Mash extends the MinHash dimensionality-reduction technique to include a pairwise mutation distance and P value significance test, enabling the efficient clustering and search of massive sequence collections. Mash reduces large sequences and sequence sets to small, representative sketches, from which global mutation distances can be rapidly estimated. We demonstrate several use cases, including the clustering of all 54,118 NCBI RefSeq genomes in 33 CPU h; real-time database search using assembled or unassembled Illumina, Pacific Biosciences, and Oxford Nanopore data; and the scalable clustering of hundreds of metagenomic samples by composition. Mash is freely released under a BSD license ( https://github.com/marbl/mash ).
Given a massive collection of sequences, it is infeasible to perform pairwise alignment for basic tasks like sequence clustering and search.
CW/CA (Collision Warning /Collision Avoidance) Systems have been an active research and development area as interests and demands for the advanced vehicle increase. A CW/CA Hardware-in-the-Loop Simulation (HiLS) system has been designed and used to test a CW/CA algorithm, radar sensors, and warning displays under realistic operating conditions in the laboratory. A CW/CA algorithm has two parts. One is a distance decision algorithm that determines the critical warning and braking distance and the other is a brake control algorithm for collision avoidance. The CW/CA HiLS system consists of a controller in which a DSP chip is installed, a preceding vehicle simulator, a radar sensor and a warning display. The controller calculates velocities of the preceding and following vehicles, relative distance and relative velocity of the vehicles using vehicle simulation models. The relative distance and velocity are applied to the vehicle simulator that is controlled by a DC motor. The relative distance of ...
The project Early Language Learning in Europe (ELLiE) has studied the longitudinal effects of an early foreign language (FL) start in seven European contexts. This article presents a sub-study of ELLiE that investigates the impact of out-of-school factors on learners listening and reading skills in year four of formal FL instruction. More specifically, we include Parents educational level, parents use of the FL professionally, exposure, interaction and cognate linguistic distance. Data were collected by means of listening and reading tests and a parents questionnaire. Results of the statistical analyses show that cognate linguistic distance was the strongest predictor of both listening and reading scores, followed closely by exposure, and parents FL use at work and international interaction at some distance. Parents educational levels only impacted on reading scores, and domestic interaction did not have any effect on listening or reading. Furthermore, the results confirm previous research ...
Background: Combinatorial works on genome rearrangements have so far ignored the influence of intergene sizes,i.e. the number of nucleotides between consecutive genes, although it was recently shown decisive for the accuracyof inference methods (Biller et al. in Genome Biol Evol 8:1427-39, 2016; Biller et al. in Beckmann A, Bienvenu L, JonoskaN, editors. Proceedings of Pursuit of the Universal-12th conference on computability in Europe, CiE 2016, Lecturenotes in computer science, vol 9709, Paris, France, June 27-July 1, 2016. Berlin: Springer, p. 35-44, 2016). In this line, wedefine a new genome rearrangement model called wDCJ, a generalization of the well-known double cut and join (orDCJ) operation that modifies both the gene order and the intergene size distribution of a genome.Results: We first provide a generic formula for the wDCJ distance between two genomes, and show that computingthis distance is strongly NP-complete. We then propose an approximation algorithm of ratio 4/3, and two exact ones:a
The overall aims of the studies were to investigate the effects of different training modalities on exercise capacity and health-related quality of life (HRQoL) in patients with moderate or severe COPD and, further, to explore two of the physical tests used in pulmonary rehabilitation.. In study I, the 12-minute walking distance (12MWD) did not increase on retesting in patients with exercise-induced hypoxemia (EIH) whereas 12MWD increased significantly on retesting in the non-EIH patients. In study II, we found that the incremental shuttle walking test was as good a predictor of peak exercise capacity (W peak) as peak oxygen uptake (VO2 peak) is. In study III, we investigated the effects of two different combination training programmes when training twice a week for eight weeks. One programme was mainly based on endurance training (group A) and the other on resistance training and callisthenics (group B). W peak and 12MWD increased in group A but not in group B. HRQoL, anxiety and depression ...

David J. Lederer, M.D., of the Division of Pulmonary, Allergy and Critical Care Medicine at Columbia University College of Physicians and Surgeons in New York City, and five associates examined the records of 454 adult IPF patients on U.S. transplantation waiting lists. In IPF, lung tissue is damaged by an unknown cause. The walls of the air sacs become inflamed, which leads to scarring or fibrosis. As a result, patients with IPF frequently suffer from progressive respiratory failure. Eventually, the scarring causes permanent loss of the lungs ability to transport oxygen. To date, lung transplantation is the only medical therapy that has been shown to improve survival. Twenty-percent of all lung transplant procedures performed worldwide involve patients with IPF. The investigators call the six-minute walk test a simple, safe, reliable and inexpensive way to assess the self-paced exercise capacity of IPF patients. It varies little when repeated on the same person over a short period of ...

When using tools effects in body space and distant space often do not correspond. Findings so far demonstrated that in this case visual feedback has more impact on action control than proprioceptive feedback. The present study varies the dimensional overlap between visual and proprioceptive action effects and investigates its impact on aftereffects in motor responses. In two experiments participants perform linear hand movements on a covered digitizer tablet to produce ∩-shaped cursor trajectories on the display. The shape of hand motion and cursor motion (linear vs. curved) is dissimilar and therefore does not overlap. In one condition the length of hand amplitude and visual target distance is similar and constant while the length of the cursor path is dissimilar and varies. In another condition the length of the hand amplitude varies while the lengths of visual target distance (similar or dissimilar) and cursor path (dissimilar) are constant. First, we found that aftereffects depended on the
Purpose: A prototype device was developed to allow individuals to hear ultrasound reflections off environmental obstacles. Previous studies have shown that this device allows for better distance judgement than audition and allows for effective passag
In shooting sports, a shot grouping, or simply grouping, is the pattern of projectile impacts on a target from multiple shots taken in one shooting session. The tightness of the grouping (the proximity of all the shots to each other) is a measure of the precision of a weapon, and a measure of the shooters consistency and skill. On the other hand, the grouping displacement (the distance between the calculated group center and the intended point of aim) is a measure of accuracy. Tightness of shot groupings are calculated by measuring the distance between bullet holes on the target (center-to-center) in length measurements such as millimeters or inches. Often that measurement is converted into angular measurements, such as milliradians (mils) or minutes of angle (MOAs), which expresses the size of shot spreads regardless of the target distance. Thus, by using angular measurements, one can reliably compare the relative tightness of shot groupings fired at different distances. For firearms that ...
Monday - We completed two labs on Monday. In the first, we separated the pigments found in a leaf of spinach using a technique called paper chromatography. Using an organic solvent, the four pigments in a spinach leaf travel different distances on a piece of paper so that the students can see that green is not the only color of the pigments in a plant. While that experiment was running (it takes awhile for the solvent to travel on the paper), the students looked at the structure of a leaf under the microscope. For homework, the students completed any of the lab questions that they did not complete in class ...
There is a part of the race that you know is coming as a half marathoner but you still dread it. Given the nature of running three different distances on virtually the same course and the same finish line, but heading in multiple directions provides a little bit of a problem. To make this all work there is a ¾ mile-section that only the half marathoners have to do. You know this is coming because the mile markers for the 20 miler and the marathon are in the same place with the markers for the half being 4 minutes of running further down the path. I remembered this from last years 20 miler and knowing how much of a mental game this can play with you, was prepared for it. It doesnt matter if you can see the finish line if you know you still have 2 miles to run. So I flipped the psychosis of the course and thought I would just run as hard as possible to make it hurt for less time ...
In experiment 1, we demonstrated that the visual system compensates for the effects of spatial frequency to achieve depth constancy. In that experiment, however, the standard and comparison were presented at the same viewing distance, so the predictions for depth constancy and disparity matching (setting the peak-to-trough disparities to the same value) were the same. By putting the standard and comparison at different distances, these two predictions are dissociated. In experiment 2, if subjects failed to take distance into account and simply matched the disparities at the retina, then the data would fall on horizontal lines through the squares, which represent the disparities of the standard (disparity matching). Those lines are not shown in the figures, but such data would be a failure of depth constancy. If, on the other hand, observers saw the same depth variation when the two stimuli specified the same peak-to-trough depth in the world, then they would require more disparity in the ...

We explore interactive relief shearing, a set of non-intrusive, direct manipulation interactions that expose depth and shape information in terrain maps using ephemeral animations. Reading and interpreting topography and relief on terrain maps is an important aspect of map use, but extracting depth information from 2D maps is notoriously difficult. Modern mapping software attempts to alleviate this limitation by presenting digital terrain using 3D views. However, 3D views introduce occlusion, complicate distance estimations, and typically require more complex interactions. In contrast, our approach reveals depth information via shearing animations on 2D maps, and can be paired with existing interactions such as pan and zoom. We examine explicit, integrated, and hybrid interactions for triggering relief shearing and present a version that uses device tilt to control depth effects. Our evaluation shows that these interactive techniques improve depth perception when compared to standard 2D and perspective
One of our projects applications is a suspension rod. Lets imagine a pointer used in class lectures. The rod contains many cylinders and can extend and shrink by changing a relative distance of each cylinder. Inner cylinder corresponds to the DNA cylinder and outer one does to the DNA ring in our project. In addition, how the rod stretch can be controlled by ordering DNA strands. For example, the rod, which has zigzag-placed strands in parallel to the cylinders axis, can shrink and suspend spontaneously. // By using suspending movement, our DNA screw can measure kinetic properties. In detail, the DNA screw has FRET and emits fluorescence when the relative distance between the ring and cylinder changes in preparation. Then, the DNA screw is attached to an object such as a protein. The kinetic force is detectable by observing FRETs emission. Compared to AFM, this method can observe one proteins elastic force. // Furthermore, this DNA suspension rod can provide a dynamical creating methodology ...
Connectivity based clustering, also known as hierarchical clustering, is based on the core idea of objects being more related to nearby objects than to objects farther away. These algorithms connect objects to form clusters based on their distance. A cluster can be described largely by the maximum distance needed to connect parts of the cluster. At different distances, different clusters will form, which can be represented using a dendrogram, which explains where the common name hierarchical clustering comes from: these algorithms do not provide a single partitioning of the data set, but instead provide an extensive hierarchy of clusters that merge with each other at certain distances. In a dendrogram, the y-axis marks the distance at which the clusters merge, while the objects are placed along the x-axis such that the clusters dont mix.. Connectivity based clustering is a whole family of methods that differ by the way distances are computed. Apart from the usual choice of distance ...
A suspension of MS2, an Escherichia coli bacteriophage virus, was used to artificially contaminate the hands of participants prior to using three different handdrying devices: jet air dryer, warm air dryer, paper towel dispenser. Virus was detected by plaque formation on agar plates layered with the host bacterium. Vertical dispersal of virus was assessed at a fixed distance (0.4 m) and over a range of different heights (0.0 - 1.8 m) from the floor. Horizontal dispersal was assessed at different distances of up to three metres from the hand-drying devices ...
Taking an image with our eyes. The eyes work in exactly the same way as a camera. Light from an object gets focused by the cornea, aqueous humor, and lens onto the retina. By adjusting the shape of the lens, clear images of objects at different distances can be formed. Note that the images on retina are actually upside down, but our brain has evolved to adjust this so we see the world properly.. The retina is the innermost of three tissue layers that make up the eyeball. The outermost layer, called the sclera, is what gives most of the eyeball its white color. The middle layer between the retina and sclera is called the choroid. The choroid contains blood vessels that supply the retina with nutrients and oxygen and remove its waste products.. Embedded in the retina are millions of light sensitive cells, which come in two main varieties: rods and cones. Rods are used for monochrome vision in poor light, while cones are used for color and for the detection of fine detail. Cones are packed into a ...
Light enters the eye through the anterior (or front) part of the eye where it passes first through the cornea and then lens which focus the light into a distinct beam. This light beam then moves through the middle of the eye and ends up on the back of the eye (retina) which is compsed of a light-sensitive membrane that translates the light into electrical signals which are, in turn, sent to the brain through the optical nerve (Figure 1).. The cornea is the outermost transparent layer in the anterior part of the eye and is responsible for most of the focus or dioptric power. The curvature of the cornea determines how well the light is focused. After light leaves the cornea it passes through the lens which is flexible and can change shape to help you see at different distances (accommodation) (Figure 2).. ...

Twenty patients with glaucomatous visual field (24-2) defects (ages 40 to 85 years) and 30 age-similar controls were recruited from a longitudinal glaucoma study. Subjects were imaged with Spectralis OCT (V 5.4, Heidelberg Engineering, GmbH) using the posterior pole protocol. A 64-cell grid is superimposed on a 24°×24° area of the macula, and was manually adjusted to be centered on the fovea; the central line of this grid was oriented in the same direction as the foveal-disc angle. We demarcated 3 zones per hemifield within the central ±8°, where we had found the lowest variability. Asymmetry was calculated as the difference between the average thicknesses of a superior zone and the corresponding inferior zone. In order to validate our findings, high-density scans were used with 10 of the 20 patients to derive en face images of the RNFL bundles at different distances from the inner limiting membrane.. ...
This is when the lens of the eye becomes cloudy and hard to see through. In a normal eye, the lens is almost transparent. Its job is to focus the things we are looking at onto the retina at the back of the eye so we can see objects at different distances clearly. Cloudiness of the lens causes dimming of the eyesight and fuzzy images. Cataracts are usually caused by exposure to too much sunlight or by aging. In young infants with galactosemia, cataracts may be caused by the buildup of galactose and other substances in the blood ...

This paper describes the step-by-step process of characterizing tephra-fall deposits based on isopach, isomass and isopleth maps as well as thickness transects at different distances from their source. It covers the most frequently used empirical methods of integration (i.e., exponential, power-law and Weibull) and provides a description of the key physical parameters that can be retrieved from tephra-fall deposits. To streamline this process, a Matlab function called TephraFits is proposed, which is highly customizable and also guides the interpretation of the results. The function calculates parameters such as the deposit volume/mass, the VEI/magnitude, and the rates of thickness-decay away from the source and assists in eruption classification using deposit-based schemes. The function also contains a stochastic mode that can be used to propagate the uncertainty from field data to the quantification of eruption source parameters. The use of this function is demonstrated using the the 1180 ±80 years B
The mechanisms described above - collectively referred to as acclimation - are triggered within the plant by environmental cues, of which the most important are seasonal changes in daylength and temperature. Differences among plant species range from the purely photoperiodic in which temperature plays almost no role to those that are purely temperature-controlled with no response to photoperiod (i.e., daylength). Most plants fall somewhere between these two extremes. In spring, once daylength extends beyond a certain point - known as critical daylength - deacclimation is initiated in photo-periodically sensitive species, active growth is triggered, and the plant will not become quiescent again until the shortened daylengths again trigger acclimation the following fall. Because the daylengths differ throughout the year at different distances from the equator, the cues that trigger spring growth (and winter acclimation as well) in a plant of Floridian provenance will be slightly different than ...
It is scarcely possible to avoid comparing the eye to a telescope. We know that this instrument has been perfected by the long-continued efforts of the highest human intellects; and we naturally infer that the eye has been formed by a somewhat analogous process. But may not this inference be presumptuous? Have we any right to assume that the Creator works by intellectual powers like those of man? If we must compare the eye to an optical instrument, we ought in imagination to take a thick layer of transparent tissue, with a nerve sensitive to light beneath, and then suppose every part of this layer to be continually changing slowly in density, so as to separate into layers of different densities and thicknesses, placed at different distances from each other, and with the surfaces of each layer slowly changing in form. Further we must suppose that there is a power always intently watching each slight accidental alteration in the transparent layers; and carefully selecting each alteration which, ...
