Detection of persistent signals and its relation to coherent feed-forward loops [PDF]

Royal Society Open Science, 2018
Many studies have shown that cells use the temporal dynamics of signalling molecules to encode information. One particular class of temporal dynamics is persistent and transient signals, i.e. signals of long and short duration, respectively.

Research on borehole transient electromagnetic positioning method of azimuthal coil scanning detection

Meitan xuebao
The borehole transient electromagnetic method is used to detect the long-range water-bearing bodies around the borehole wall by using the advanced water exploration borehole in the heading roadway, which avoids the “one’s opinion in one hole” because the

Detection of transient fluorine atoms [PDF]

AIP Conference Proceedings, 1986
A KrF excimer laser with a fluence of 50 mJ/cm2 was used to photolyze either uranium hexafluoride or molecular fluorine, yielding a transient number density of fluorine atoms. The rise and decay of the atomic fluorine density was observed by transient absorption of a 404-cm−1 Pb-salt diode laser, which corresponds to the 2P3/2 → 2P1/2 spin-orbital ...

PEARLS: 21 Transients Found in the Three-epoch NIRCam Observations in the Continuous Viewing Zone of the James Webb Space Telescope

The Astrophysical Journal
We present 21 transients from our three-epoch, four-band NIRCam observations covering 14.16 arcmin ^2 in the Spitzer IRAC Dark Field (IDF), taken by the JWST Prime Extragalactic Areas for Reionization and Lensing Science program with a time cadence of ∼6

Transient Fault Detection in Networked Control Systems

International Journal of Distributed Sensor Networks, 2014
Transient faults appear unpredictablly and frequently in networked control systems (NCSs), which directly affect the safety of system. However, they can not be accurately identified due to various kinds of causes, so the detection of them needs more ...

Differencing and Coadding JWST Images with Matched Point-spread Function

The Astronomical Journal
We present an algorithm to derive difference images for data taken with JWST with matched point-spread functions (PSFs). It is based on the saccadic fast Fourier transform method but with revisions to accommodate the rotations and spatial variations of ...

Power Load Event Detection and Classification Based on Edge Symbol Analysis and Support Vector Machine

Applied Computational Intelligence and Soft Computing, 2012
Energy signature analysis of power appliance is the core of nonintrusive load monitoring (NILM) where the detailed data of the appliances used in houses are obtained by analyzing changes in the voltage and current.

Research and Design of a Transmission System for Time-Frequency-Domain Electromagnetic Method

IEEE Access, 2019
In electromagnetic sounding, the detection areas of time-domain and frequency-domain electromagnetic detection methods cannot be effectively connected, and the detection processes for these two methods must be implemented separately.

Strategies optimize the detection of motion transients

Journal of Vision, 2006
Strategies are implicitly formed when a task is consistent and can be used to improve performance. To investigate how strategies can alter perceptual performance, I trained animals in a reaction time (RT) detection task in which the probability of a fixed duration motion pulse appearing varied over time in a consistent manner.

Transient Stability Analysis of Grid-Forming Inverters Incorporating Detection Delays in Active-Power Reference Reduction Strategies

International Journal of Electrical Power & Energy Systems
Reducing the active-power reference of grid-forming inverters during voltage sags is an effective approach for maintaining transient synchronism. However, its performance critically depends on the detection delay preceding derating activation.
