Acoustic device and method for measuring gas densities [PDF]

, 1992
Density measurements can be made in a gas contained in a flow through enclosure by measuring the sound pressure level at a receiver or microphone located near a dipole sound source which is driven at constant velocity amplitude at low frequencies ...

Smart pressure transmitters

Measurement and Control, 1984
This paper describes an approach to the measurement of pressure using microprocessor technology. The approach taken is to utilize the flexibility inherent in a microprocessor to increase the accuracy and versatility of the transducer, while retaining the traditional output signal format of a 4–20 mA analogue current signal representing the total input ...

Co‐overexpression of the caloric restriction‐induced mitochondrial factors PGC‐1α and MIPEP upregulates Phospho1 expression in adipocytes

FEBS Open Bio, EarlyView.
Caloric restriction that extends lifespan induces the expression of PGC‐1α and MIPEP in white adipose tissue. In this study, co‐overexpression of Pgc‐1α and Mipep upregulated the gene expression of PHOSPHO1. These findings provide new insights into mitochondria‐related mechanisms underlying the effects of caloric restriction in adipocytes.

Risk analysis of the Unity 1.5T MR‐Linac adapt‐to‐shape workflow

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background and Purpose The adapt‐to‐shape (ATS) workflow on the Unity MR‐Linac (Elekta AB, Stockholm, Sweden) allows for full replanning including recontouring and reoptimization5. Additional complexity to this workflow is added when the adaptation involves the use of MIM Maestro (MIM Software, Cleveland, OH) software in conjunction with ...

A Learning Theoretic Approach to Energy Harvesting Communication System Optimization

, 2012
A point-to-point wireless communication system in which the transmitter is equipped with an energy harvesting device and a rechargeable battery, is studied. Both the energy and the data arrivals at the transmitter are modeled as Markov processes.

The Impact of CSI and Power Allocation on Relay Channel Capacity and Cooperation Strategies

, 2007
Capacity gains from transmitter and receiver cooperation are compared in a relay network where the cooperating nodes are close together. Under quasi-static phase fading, when all nodes have equal average transmit power along with full channel state ...

Enhanced analysis of gating latency in 0.35T MR‐linac through innovative time synchronization of a motion phantom and plastic scintillation detector

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study aims to evaluate how different gantry angles, breathing rates (BPM), cine image speeds, and tracking algorithms affect beam on/off latency and the subsequent impact on target dose for a 0.35T MR‐Linac with a 6 MV FFF beam.
