Fast Dark Signal Measurements of SVOM VT CCDs Using the Vertical Gradient of Dark Field Images

open access: yesPhotonics, 2021
This paper describes a fast technique for estimating the dark signals of the charge coupled devices (CCDs) of the visible telescope (VT) onboard the space multi-band variable object monitor (SVOM).

An Adaptive Management Model for Brown Bears in Hokkaido: Based on Total Population and the Number of Nuisance Bears

open access: yesPopulation Ecology, EarlyView.
Bear management changes management actions according to the horizontal axis of the population size and the vertical axis of the number of nuisance bears. Aiming for the target population size of Ntar, Actions I and II protect the bears, and Action IV reduces the population.

Theoretical and experimental analysis of acoustic emission signal for resonant sensor on homogenous material

open access: yesSensing and Bio-Sensing Research, 2023
The modelling of AE signal has been conducted for AE resonant sensor. For surface loading, the generation of acoustic emission (AE) signal has been developed and simulated in this paper for two homogenous materials.

Mechanisms and kinetic assays of aminoacyl‐tRNA synthetases

open access: yesFEBS Letters, EarlyView.
Accurate protein synthesis is crucial for life. The key players are aminoacyl‐tRNA synthetases (AARSs), which read the genetic code by pairing cognate amino acids and tRNAs. AARSs establish high amino acid selectivity by employing physicochemical limits in molecular recognition.

A Unified Frequency Domain Model to Study the Effect of Demyelination on Axonal Conduction

open access: yesBiomedical Engineering and Computational Biology, 2016
Multiple sclerosis is a disease caused by demyelination of nerve fibers. In order to determine the loss of signal with the percentage of demyelination, we need to develop models that can simulate this effect. Existing time-based models does not provide a

A method for closed loop automatic tuning of PID controllers [PDF]

open access: yesModeling, Identification and Control, 1992
A simple method for the automatic tuning of PID controllers in closed loop is proposed. A limit cycle is generated through a nonlinear feedback path from the process output to the controller reference signal.

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Development of the PSO method for the determination of the dynamic response of a pyroelectric sensor

open access: yesInternational Journal of Metrology and Quality Engineering, 2016
We modeled a pyroelectric sensor by a current source connected in parallel with output impedance. The dynamic behavior of the sensor is described using a transfer function designed using the MATLAB Simulink environment.

Synthesis of transfer functions by signal-flow graphs

open access: yesElectronics Letters, 1974
A new procedure is given for the synthesis of voltage transfer functions. It is shown that the well known circuits of Lovering and Brugler can also be derived easily by this method. It is also indicated that a simplification can be obtained in the RC:-RC decomposition method. which is in the proposed procedure.
