Current-controlled logic and single electron logic processors have been investigated with respect to thermal-induced bit error. A maximal error rate for both logic processors is regarded as one bit-error/year/chip. A maximal clock frequency and an information channel capacity at a given operation current are derived when a current-controlled logic processor works without error. An available operation range in a current-controlled processor with 100 million elements is discussed. The dependence of an error-free condition on temperature in single electron logic processors is derived. The size of the quantum dot of single electron transistor is predicted when a single electron logic processor with the a billion single electron transistors works without error at room temperature.

Most individuals who die by suicide have contact with a physician in the year before their death. There are no randomized trials that have evaluated suicide intervention training for medical students or physicians. The objective of this study was to determine the effectiveness of a gatekeeper training program on suicide intervention behavior using Objective Structured Clinical Examinations (OSCEs) in medical students. A randomized controlled trial design was used. Participants were 112 undergraduate medical students at the University of Manitoba. The 2-day Applied Suicide Intervention Skills Training (ASIST) program was completed by half of the participants, according to a stratified block randomization design. Scores on OSCEs and scores on the Suicide Intervention Response Inventory (SIRI-2) were used as objective measures of intervention behaviors. There was a a significant Group-by-Time interaction on OSCE data, demonstrating that medical students who received ASIST performed significantly better than medical students who received training as usual (p<.001). The two groups did not differ significantly from each other on the SIRI-2 (p=.78). ASIST training improved the ability of medical students to detect and intervene with a standardized suicidal patient as assessed by OSCEs, compared to medical school training as usual. This study provides support for ASIST training for medical students to develop skills in recognition and management of suicidal patients. / October 2015

Cobham Electronic Systems, Inc. has developed a field-programmable telemetry transmitter module for higher-power (0.1W to 25W) airborne telemetry applications. A key feature of the transmitter is high DC to RF conversion efficiency over the entire variable output power range of 25dB through the use of GaN amplifiers. This high efficiency is realized by using a variable voltage DC-DC converter and dynamic bias control of the GaN amplifier elements. This feature is useful in that output power can be tailored to mission requirements and timelines, thereby extending battery life and increasing operation time. The transmitter receives configuration commands and can be programmed through an external data port. The transmitter can be configured for RF power and frequency over the telemetry S-Band frequency range, and has multiple data rates. The unit consists of RF, digital and power supply circuits. The RF transmitter is a PCM-FM type with a phase-locked loop, driver amplifiers, a power amplifier and a digital processor for RF control. The unit contains a digital processor, FPGA's, and flash memory. The power supplies contains all the regulator circuits to supply power to the rest of the unit, variable output drain voltage to the GaN devices, EMI filtering, under/overvoltage protection, a temperature sensor and a digital processor for power control. The electronics are housed in a compact aluminum housing.
