TDMA is a bioisosteric analogue of 3,4-methylenedioxy-N-methylamphetamine (MDMA) which was developed in an attempt to create an improved MDMA alternative for potential clinical use. [1] It is the analogue of MDMA in which the 1,3-benzodioxole ring has been replaced with a 2,1,3-benzothiadiazole ring. [1] ODMA and SeDMA are closely related ...
The Joint Tactical Information Distribution System (JTIDS) is an L band Distributed Time Division Multiple Access (DTDMA) network radio system used by the United States Department of Defense and their allies to support data communications needs, principally in the air and missile defense community.
By 1900 application of high-frequency current to the body was used experimentally to treat a wide variety of medical conditions in the quack medical field of electrotherapy. In 1899 Austrian chemist von Zaynek determined the rate of heat production in tissue as a function of frequency and current density, and first proposed using high-frequency ...
To establish a reference range, the Clinical and Laboratory Standards Institute (CLSI) recommends testing at least 120 patient samples. In contrast, for the verification of a reference range, it is recommended to use a total of 40 samples, 20 from healthy men and 20 from healthy women, and the results should be compared to the published reference range.
In TDMA, each user's timeslot ends with a guard interval. Thus, the guard interval protects against data loss within the same timeslot, and protects the following user's timeslot from interference caused by propagation delay. It is a common misconception that TDMA timeslots begin with the guard interval, as with OFDM.
MF-TDMA ("Multi-frequency time-division multiple access") is a technology for dynamically sharing bandwidth resources in an over-the-air two-way communications network.
Medical device connectivity is the establishment and maintenance of a connection through which data is transferred between a medical device, such as a patient monitor, and an information system. The term is used interchangeably with biomedical device connectivity or biomedical device integration.
Tactical Combat Casualty Care (TCCC or TC3), formerly known as Self Aid Buddy Care, [1] is a set of guidelines for trauma life support in prehospital combat medicine published by the United States Defense Health Agency. They are designed to reduce preventable deaths while maintaining operational success.
