Since chemosensory genes play key roles in insect behaviour, they can potentially be used as new targets for pest control. The cabbage beetle, Colaphellus bowringi, is a serious insect pest of cruciferous vegetables in China and other Asian countries. However, a systematic identification of the chemosensory genes expressed in the antennae has not been reported. We assembled the antennal transcriptome of C. bowringi by using Illumina sequencing technology and identified 104 candidate chemosensory genes by analyzing transcriptomic data, which included transcripts encoding 26 odorant-binding proteins (OBPs), 12 chemosensory proteins (CSPs), four sensory neuron membrane proteins (SNMPs), 43 odorant receptors (ORs), nine ionotropic receptors (IRs), and ten gustatory receptors (GRs). The data obtained are similar to those found in other coleopteran species, suggesting that our approach successfully identified the chemosensory genes of C. bowringi. The expression patterns of 43 OR genes, some of which were

Olfaction presents the ultimate challenge to molecular recognition as thousands of molecules have to be recognized by far fewer olfactory receptors. We have presented evidence that Drosophila readily distinguish odorants based on their molecular vibrations using a battery of behavioral assays suggesting engagement of a molecular vibration-sensing component. Here we interrogate electrophysiologically the antennae of four Drosophilids and demonstrate conserved differential response amplitudes to aldehydes, alcohols, ketones, nitriles and their deuterated isotopologues. Certain deuterated odorants evoked larger electroantennogram (EAG) amplitudes, while the response to the normal odorant was elevated in others. Significantly, benzonitrile isotopologues were not distinguishable as predicted. This suggests that isotopologue-specific EAG amplitudes result from differential activation of specific olfactory receptors. In support of this, odorants with as few as two deuteria evoke distinct EAG amplitudes ...

An ablation treatment apparatus has a multiple antenna device with a primary antenna and a secondary antenna. The secondary antenna is positioned in a lumen of the primary antenna as the primary antenna is introduced through tissue to a selected tissue site. At the tissue site the secondary antenna is deployed from the primary antenna in a lateral direction relative to a longitudinal axis of the primary antenna. At least a portion of a distal end of the secondary antenna is structurally less rigid than the primary antenna. The primary antenna is constructed to be rigid enough to be introduced and advanced through tissue. A cable couples the energy source to one or more of the antennas.

Here is the practical method. I just scribbled it on my iPad. You may download it as a PDF file. :-) - Thierry. Thierry, I have seen something similar to this (The EPE-2008 theremin had a on-board circuit to assist tuning) - but, in playing with the EPE circuit, I found the operation of this circuit unsatisfactory.. My understanding (and my experiments) indicate that maximum loading on the oscillator occurs at the resonant frequency of the antenna circuit (coils + antenna capacitance).. and that one wants the hand capacitance seen by the antenna to be at the position one requires for the null point (about 60cm from the antenna). The resistance inserted between the oscillator and antenna circuit allows the oscillator frequency to be adjusted without being effected by the antenna loading - so one can find (by looking for peak current) the resonant frequency of the antenna circuit.. However, as soon as the 100k (or whatever value is used to isolate the antenna from the oscillator) is replaced ...

A passive reflective antenna located near an active receiving antennas is used to change the energy at the receiving antenna. The change in energy may be such as to remove a null created by multipath or to provide directionality, or both. The receiving antennas is permanently connected to a single receiver. When the receivers output signal degrades below an acceptable level of quality, the reflective phase of the passive antennas load is changed to change the phase of the reflected energy and achieve a desired effect (remove a null, change directionality, etc.) at the receiving antenna. In the simplest embodiment, the termination of the passive antenna is switched from an open circuit to a short circuit, or vice versa, to invert the phase of the reflected energy. The use of reflective elements in antenna designs, usually to achieve directionality, is well known (see the common Yagi or corner reflector antenna designs, for example), but these use passive reflector elements.

The antennal lobe is the deutocerebral neuropil of insects which receives the input from the olfactory sensory neurons on the antenna. Functionally, it shares some similarities with the olfactory bulb in vertebrates.. In insects, the olfactory pathway starts at the antennae (though in some insects like Drosophila there are olfactory sensory neurons in other parts of the body) from where the sensory neurons carry the information about the odorant molecules impinging on the antenna to the antennal lobe.[1] The antennal lobe is composed of densely packed neuropils, termed glomeruli, where the sensory neurons synapse with the two other kinds of neurons, the projection neurons and the local neurons.[1] There are 43 glomeruli in the Drosophila antennal lobe; in Aedes aegypti there are 32;[1] locusts and social wasps may have over 1000.[1] The projection neurons project to higher brain centers such as the mushroom body and the lateral horn.[2] [3] [4] The local neurons, which are primarily inhibitory, ...
We conducted Ribonucleic Acid sequencing analysis of the codling moth antennal transcriptome and identified 66 odorant receptors (ORs) in a population from Xinjiang province, China; of which 14 were PRs, including two novel PRs (CpomOR2e and CpomOR73). Sex pheromones that in most cases attract males to virgin females have been the most extensively used in IPM, especially with lepidopteran pests. Typical alarm behavior is produced also by homologous 2-alkanones with a chain length of 6-9 carbon atoms. Pheromones are released by insects and other organisms into the environment in order to communicate with others of the same species. The transmission of information by insects is carried out with the help of special odorous substances called pheromones, SUMMARY1 Chemical communication plays an important part in the lives of insects, and particularly in lives of those that live in groups or social organizations.

A system and method are described for using RFID tags to track and monitor personnel and equipment in large environments and environments that are prone to multipath fading. The system scans the environment by selecting local interrogation zones where RFID tags may be located. Multiple antennae are used, each transmitting a portion of an activation signal, such that the activation signal will be formed in the selected local interrogation zone. Different subsets of the antennae are successively selected, each targeting the selected local interrogation zone, to repeat the activation signal for each subset of antenna. RFID tags in the local interrogation zone will receive the portions of the activation signals and process them to determine whether the full activation signal was destined for that local interrogation zone for each of the subsets of antennae. An activated RFID tag will transmit its tag information, including any data collected from sensors connected to the tag, back to the system. The systems
An antenna circuit to be used in conjunction with a chip transponder such that the antenna circuit serves for both the reception of interrogative signals intended for the transponder as well as for response signals that ape to be transmitted by the transponder. The antenna circuit has at least one magnetic circuit of high μ material, and is formed of ceramic core means, that have been built into a depression in a thick-walled surface intended to receive the chip transponder. This thick-walled surface may be of metal. The ceramic core means comprise at least a ceramic core resonator and half a ceramic core that functions as an antenna with its open side facing outward. In one aspect, the ceramic core resonator and the half ceramic core antenna are coupled by means of one or more secondary coils of the closed ceramic core, which also form the coils of the half ceramic core antenna. In another aspect, the secondary coil forms a resonating circuit with at least one capacitive element in series. In yet
Citation: Byers, J.A. 2013. Modeling and regression analysis of semiochemical dose-response curves of insect antennal reception and behavior. Journal of Chemical Ecology. 39(8):1081-1089. Interpretive Summary: Semiochemicals are released by organisms that when perceived by another organism cause it to change behavior. Insects use semiochemicals for communication, to find mates, or to locate or assess host plants. Many insect species have been studied to determine the relationship between concentration (dose) of a specific semiochemical and the corresponding insect behavioral response. Although it is generally recognized that these dose-response relationships are not linear, little information exists to indicate the true functional relationship between semiochemical dose and insect response. A computer simulation using a hypothetical insect antenna and a wide range of semiochemical doses indicated a family of mathematical equations, or functions, described the dose-response relationship nearly ...

A device and method is disclosed for creating a lesion in nerve-containing tissue spaced from a body lumen while protecting tissue forming and adjacent to a wall of the body lumen from injury. A catheter carrying a microwave antenna is positioned within the body lumen. Cooling fluid is circulated around the microwave antenna in thermal contact with the wall of the body lumen. Power is supplied to the microwave antenna to cause microwave energy to be emitted omnidirectionally from the microwave antenna. The power supplied to the microwave antenna and the cooling fluid circulated around the microwave antenna are controlled to cause the nerve-containing tissue spaced from the body lumen to be heated to a temperature sufficient to cause thermal damage while the tissue forming and adjacent to the wall of the body lumen is maintained at a temperature where thermal damage does not occur.

Bristletails are primitive wingless insects. At first glance they resemble silverfish, however silverfish have three abdominal filaments nearly equal in length. In bristletails, the central filament is much longer than the side two. Unlike silverfish, bristletails have well developed compound eyes. The compound eyes are large and meet on the back of the head. Three simple eyes (ocelli) also occur on bristletails. Bristletails have well developed mandibles which are partially hidden in the head. The antennae are long and resemble a chain of beads (moniliform). Bristletails are usually nocturnal and have an interesting habit of arching and flexing the body to give a springing action similar to springtails. Bristletails are found in litter, moss, lichens and other similar habitats ...
A stacked patch antenna has a first element having a feed thereto spaced above a ground plane and one or more spaced apart parasitic elements spaced above the first element. The first and parasitic elements may be tuned to a fundamental mode for radiation of a specified frequency. The geometric centers of the parasitic elements are offset from one another and from the geometric center of the first element along the same direction. The stacked patch configuration provides increased gain and bandwidth. The offset configuration determines the direction of maximum gain for the antenna. The first and parasitic elements can be single antenna elements and may be microstrip antenna elements. The elements can also be arrays of microstrip antenna elements. The phasing of the arrays of microstrip elements can be controlled to determine a gain sensitivity direction.

At 2m, youll have another 6dB of path loss, for 47dB.So the signal leaves at 17dBm (from the AP), you lose 41dB due to LOS (Line of Sight) path lossat 1m, and the signal arrives at the antenna in your laptop at perhaps -24dBm, and is raisedto -22dBm by the antenna.This is quite close to the maximum signal level of 802.11g ...
