Agent-based modeling: a systematic assessment of use cases and requirements for enhancing pharmaceutical research and development productivity. [PDF]

open access: yes, 2013
A crisis continues to brew within the pharmaceutical research and development (R&D) enterprise: productivity continues declining as costs rise, despite ongoing, often dramatic scientific and technical advances. To reverse this trend, we offer various

A Fault-Line Selection Method for Small-Current Grounded System Based on Deep Transfer Learning

open access: yesEnergies, 2022
Usually, data-driven methods require many samples and need to train a specific model for each substation instance. As different substation instances have similar fault features, the number of samples required for model training can be significantly ...

Improved transient simulation of salient-pole synchronous generators with internal and ground faults in the stator winding [PDF]

open access: yes, 2005
An improved model for simulating the transient behavior of salient-pole synchronous generators with internal and ground faults in the stator winding is established using the multi-loop circuit method.

A new approach to fault-line selection of small current neutral grounding system

open access: yesSystems Science & Control Engineering, 2018
In this paper, a new approach combining BP neural network with fuzzy Petri net (FPN) is developed to deal with the issue of fault-line selection of the small current neutral grounding system.

Measurement of the ICRH antenna phasing using antenna strap probe based diagnostic system in EAST tokamak

open access: yesNuclear Engineering and Technology, 2022
To operate the ion cyclotron resonance heating (ICRH) antennas in a better heating state and produce relatively low impurities, it is necessary to control the antenna spectrum by changing the antenna phasing.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
