Includes Sociology and Anthropology.Research Personnel: Those individuals engaged in research.Temporomandibular Joint Dysfunction Syndrome: A symptom complex consisting of pain, muscle tenderness, clicking in the joint, and limitation or alteration of mandibular movement. The symptoms are subjective and manifested primarily in the masticatory muscles rather than the temporomandibular joint itself. Etiologic factors are uncertain but include occlusal dysharmony and psychophysiologic factors.Temporomandibular Joint Disorders: A variety of conditions affecting the anatomic and functional characteristics of the temporomandibular joint. Factors contributing to the complexity of temporomandibular diseases are its relation to dentition and mastication and the symptomatic effects in other areas which account for referred pain to the joint and the difficulties in applying traditional diagnostic procedures to temporomandibular joint pathology where tissue is rarely obtained and x-rays are often inadequate or nonspecific. Common diseases are developmental abnormalities, trauma, subluxation, luxation, arthritis, and neoplasia. (From Thoma's Oral Pathology, 6th ed, pp577-600)Temporomandibular Joint: An articulation between the condyle of the mandible and the articular tubercle of the temporal bone.Encyclopedias as Topic: Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject.

A novidade fica por melhorias no sensor de digitais chamado de Touch ID, alumínio série 7000 na construção e várias melhorias internas de câmera e hardware. Foi introduzida no iPhone 6s a nova tecnologia chamada de 3D Touch, que usa o reconhecimento de pressão na tela para permitir que diferentes ações possam ser realizadas dependendo do nível de pressão do toque do usuário. Apesar de ser similar ao Force Touch usado no MacBook e no Apple Watch, o 3D Touch é mais sensível e consegue reconhecer mais níveis de pressão de toque do que o Force Touch.O design do iPhone 6s é praticamente idêntico ao do iPhone 6. Pela primeira vez em quatro anos, a câmera traseira do iPhone agora tem 12 MP, e passou a gravar vídeos em resolução 4K. A sua câmera dianteira possui 5 MP e a tela do iPhone pode ser agora inteiramente iluminada, usando a tecnologia chamada de "Retina Flash", que durante alguns segundos ilumina o display em até 3x mais, funcionando como um grande flash para que ...
In the 2000s, it was common for smartphones to have a physical T9 numeric keypad or QWERTY keyboard in either a candybar or sliding form factor. Some smartphones had resistive touchscreens, which allowed for virtual keyboards and handwriting input with a finger or a stylus, thus also allowing easy entry of Asian characters.. In 2007, the LG Prada was the first mobile phone released with a large capacitive touchscreen. Later that year, Apple Computer introduced the iPhone. The iPhone was also designed around a large capacitive touchscreen, but added support for multi-touch gestures (for interactions such as "pinching" to zoom in on photos and web pages). Such phones were notable for abandoning the use of a stylus, keyboard, or keypad typical for smartphones at the time, in favor of a capacitive touchscreen for direct finger input as its only input type. The invention of the touchscreen smartphone is often attributed to Apple, but they actually made the smartphone as we know it today ...
Shortly after the iPhone 4 was launched, some consumers reported that signal strength of the phone was reduced when touching the lower left edge of the phone, bridging one of the two locations which separates the two antennas, resulting in dropped calls in some areas with lower signal reception. In response, Apple issued a statement advising that customers should "avoid gripping [the phone] in the lower left corner" when making or receiving a call. As a consequence of this problem, it was reported on July 2, 2010 that several iPhone 4 users were planning on suing Apple and AT&T for fraud by concealment, negligence, intentional misrepresentation and defective design. The legal challenge was started by a law firm, who set up a website to recruit disenchanted iPhone 4 buyers for a lawsuit against Apple. Later that day, Apple issued another statement stating that it had discovered the cause of the "dramatic drop in bars". Apple explained how the formula it used to ...
... is the ascertaining of the position or location of a mobile phone, whether stationary or moving. Localization may occur either via multilateration of radio signals between (several) cell towers of the network and the phone, or simply via GPS. To locate a mobile phone using multilateration of radio signals, it must emit at least the roaming signal to contact the next nearby antenna tower, but the process does not require an active call. The Global System for Mobile Communications (GSM) is based on the phone's signal strength to nearby antenna masts. Mobile positioning may include location-based services that disclose the actual coordinates of a mobile phone, which is a technology used by telecommunication companies to approximate the location of a mobile phone, and thereby also its user. The technology of locating is based on measuring power levels and antenna patterns and uses the concept that a powered mobile phone always communicates wirelessly with one of the closest ...
The device is described as 2-square-foot (0.19 m2) in size. To mimic a cell phone tower, it utilizes IMSI-catcher (International Mobile Subscriber Identity) technology, which phone services use to identify individual subscribers. It emits a pilot signal made to appear stronger than that from the nearest cell tower, causing phones within its range to broadcast their IMSI numbers and electronic serial numbers (ESN). Encryption does not prevent this process; the devices can retrieve a phone's encryption session keys in less than one second, with success rates of 50-75% under "real world conditions". An aircraft-mounted device can locate a phone within 10 feet, Another source claims that by triangulating flights, a dirtbox can pinpoint a phone's location in as few as two feet. The dirtbox is a hybrid of detection, managed access and jamming technologies. According to The Wall Street Journal, "people with knowledge of the program" can determine which phones belong to suspects and ...
How often do people reverse Jenny's phone number? Did they ever discontinue use of the reversed version of Jenny's phone number in all area codes? I becha there are dimwits that might reverse a phone number they see or hear. If the reversed version Jenny's phone number was discontinued, mention it in the article. --SuperDude 03:50, 15 May 2005 (UTC) - You could possibly reach a satanic Jenny. --User:Dotto 00:37 14 Oct 2005 UTC -lol Possibly satans girlfriend?22.214.171.124 03:10, 8 February 2007 (UTC) In 1981, +1-areacode-903-5768 would not have been valid in most areas because a 0 or 1 in the second digit was reserved for area codes, while local exchanges could *not* have 0 or 1 in either of the first two digits. This was done so that calling a number like 1-234-5678 would actually reach (long distance) +1-your own area code-234-5678, something which was completely broken by issuing area codes with "wrong" middle digits from 1995 onward. In a few places which were short of numbers, this pattern ...
The StingRay is an IMSI-catcher, a controversial cellular phone surveillance device, manufactured by Harris Corporation. Initially developed for the military and intelligence community, the StingRay and similar Harris devices are in widespread use by local and state law enforcement agencies across Canada, the United States, and in the United Kingdom. Stingray has also become a generic name to describe these kinds of devices. The StingRay is an IMSI-catcher with both passive (digital analyzer) and active (cell-site simulator) capabilities. When operating in active mode, the device mimics a wireless carrier cell tower in order to force all nearby mobile phones and other cellular data devices to connect to it. The StingRay family of devices can be mounted in vehicles, on aeroplanes, helicopters and unmanned aerial vehicles. Hand-carried versions are referred to under the trade name KingFish. Extracting stored data such as International Mobile Subscriber Identity ("IMSI") numbers and Electronic ...
The mobile web refers to browser-based Internet services accessed from handheld mobile devices, such as smartphones or feature phones, through a mobile or other wireless network.. Traditionally, the World Wide Web has been accessed via fixed-line services on laptops and desktop computers. However, the web is now more accessible by portable and wireless devices. An early 2010 ITU (International Telecommunication Union) report said that with current growth rates, web access by people on the go - via laptops and smart mobile devices - is likely to exceed web access from desktop computers within the next five years. In January 2014, mobile internet use exceeded desktop use in the United States. The shift to mobile web access has accelerated since 2007 with the rise of larger multitouch smartphones, and since 2010 with the rise of multitouch tablet computers. Both platforms provide better Internet access, screens, and mobile browsers, or application-based user web experiences, than previous ...
Mobile-phone apps, SMS, and direct push notifications, etc., are not considered "something you have" and thus are not considered in the multi-factor/two-factor equation. Mobile-phone two-step authentication is more secure than single-factor password protection but suffers some security concerns. Phones can be cloned and apps can run on several phones; cell-phone maintenance personnel can read SMS texts. Not least, cell phones can be compromised in general, meaning the phone is no longer something you and only you have.. The major drawback of authentication including something that the user possesses is that the user must carry around the physical token (the USB stick, the bank card, the key or similar), practically at all times. Loss and theft are a risk. Many organizations forbid carrying USB and electronic devices in or out of premises owing to malware and data theft-risks, and most important machines do not have USB ports for the same reason. Physical tokens usually do not scale, typically ...
The first smartphone following the iPhone 4 to ship with a display of a comparable pixel density was the Nokia E6, running Symbian Anna, with a resolution of 640 × 480 at a screen size of 62.5mm. This was an isolated case for the platform however, as all other Symbian-based devices had larger displays with lower resolutions. Some older Symbian smartphones, including the Nokia N80 and N90, featured a 2.1 inch display at 259 ppi, which was one of the crispest at the time. The first Android smartphones with the same display - Meizu M9 was launched a few months later in beginning of 2011. And in October of the same year Galaxy Nexus was announced, which had a display with a better resolution. And by 2013 the 300+ ppimark was found on midrange phones such as the Moto G. From 2013-14, many flagship devices such as the Samsung Galaxy S4 and HTC One (M8) had 1080p (FHD) screens around 5-inches for a 400+ PPI which surpassed the Retina density on the iPhone 5. The latest major redesign of the ...
Mobile data collection or mobile surveys is an increasingly popular method of data collection. Over 50% of surveys today are opened on mobile devices. The survey, form, app or collection tool is on a mobile device such as a smart phone or a tablet. These devices offer innovative ways to gather data, and eliminate the laborious "data entry" (of paper form data into a computer), which delays data analysis and understanding. By eliminating paper, mobile data collection can also dramatically reduce costs: one World Bank study in Guatemala found a 71% decrease in cost while using mobile data collection, compared to the previous paper-based approach.. SMS surveys can reach any handset, in any language and in any country. As they are not dependent on internet access and the answers can be sent when its convenient, they are a suitable mobile survey data collection channel for many situations that require fast, high volume responses. As a result, SMS surveys can deliver 80% of responses in less ...
In the early 21st century, the landline telephone has declined due to the advancement of mobile network technology and the obsolescence of the old copper wire networking. Eventually these metallic networks will be deemed completely out of date and replaced by more efficient broadband and fiber optic landline connections extending to rural areas and places where telecommunication was much more sparse. Some see this happening as soon as the year 2025. In 2004, only about 45% of people in the United States between the ages of 12 and 17 owned cell phones. At that time, they had to rely on landline telephones. In just 4 years' time, that percentage climbed to about 71%. That same year, 2008, about 77% of adults owned a mobile phone. In the year 2013, 91% of adults in the United States owned a mobile phone. Almost 60% of those with a mobile had a smartphone. A National Health Interview Survey of 19,956 households by the Centers for Disease Control and Prevention released May 4, 2017 showed ...
With the strong growth in the use of smartphones, app usage has also greatly increased. Therefore, mobile marketers have increasingly taken advantage of smartphone apps as a marketing resource. Marketers aim to optimize the visibility of an app in a store, which will maximize the number of downloads. This practice is called App Store Optimization (ASO). There is a lot of competition in this field as well. However, just like other services, it is not easy anymore to rule the mobile application market. Most companies have acknowledged the potential of Mobile Apps to increase the interaction between a company and its target customers. With the fast progress and growth of the smartphone market, high-quality Mobile app development is essential to obtain a strong position in a mobile app store. Here are several models for APP marketing. 1. Content embedded mode For the most part at present, the downloadding APP from APP store is free, for APP development enterprise, need a way to flow to ...
