Attenuated Psychosis Syndrome [PDF]
Indian Journal of Psychological Medicine, 2014 Byline: M. Reddy Diagnostic and Statistical Manual of Mental Disorders, 5 [sup]th edition (DSM - 5) included attenuated psychosis syndrome (APS) in Section III under "conditions for further study". The DSM - 5 task force determined that there was insufficient evidence to warrant inclusion of APS as official mental disorder diagnosis in Section II. "The

A 7-Bit Reverse-Saturated SiGe HBT Discrete Gain Step Attenuator
IEEE Transactions on Circuits and Systems - II - Express Briefs, 2020 In this brief, the analysis, design, and measured results of a fully integrated 7-bit step attenuator implemented in a 0.25- $\mu \text{m}$ Silicon–Germanium (SiGe) BiCMOS process technology, are described. The attenuator is designed based on delicately

Attenuation correction in SPECT without attenuation map [PDF]
2011 IEEE Nuclear Science Symposium Conference Record, 2011 A method of attenuation correction in Single Photon Emission Computed Tomography (SPECT), based on emission data only is presented. The algorithm uses the well known Helgason-Ludwig consistency conditions. However, it does not attempt to find the attenuation map, but rather the correction factors for the projection data, which makes the problem simpler

Light attenuation coefficient of polarization attenuator at high attenuation level
Acta Physica Sinica, 2010 By use of the Jones vector we deduced the Jones matrix of actual polarizer and light transmission expression, as well as the light attenuation coefficient （LAC） of two polarizers. According to computation, certain error exists when using Malus-Law to calculate polarizer’s light attenuation ratio at high attenuation level.

KNSwing—On the Mooring Loads of a Ship-Like Wave Energy Converter
Journal of Marine Science and Engineering, 2019 The critical function of keeping a floating Wave Energy Converter in position is done by a mooring system. Several WECs have been lost due to failed moorings, indicating that extreme loads, reliability and durability are very important aspects.

The Bacillus subtilis TRAP protein can induce transcription termination in the leader region of the tryptophan biosynthetic (trp) operon independent of the trp attenuator RNA. [PDF]
PLoS ONE, 2014 In Bacillus subtilis, transcription of the tryptophan biosynthetic operon is regulated by an attenuation mechanism. When intracellular tryptophan levels are high, the TRAP protein binds to the 5' leader region of the nascent trp mRNA and induces ...
