Physics-Guided Deep Neural Networks for Power Flow Analysis [PDF]

IEEE Transactions on Power Systems, 2020
Solving power flow (PF) equations is the basis of power flow analysis, which is important in determining the best operation of existing systems, performing security analysis, etc. However, PF equations can be out-of-date or even unavailable due to system

Unleashing the full power of LHCb to probe stealth new physics [PDF]

Reports on progress in physics. Physical Society, 2021
In this paper, we describe the potential of the LHCb experiment to detect stealth physics. This refers to dynamics beyond the standard model that would elude searches that focus on energetic objects or precision measurements of known processes.

Design and Emulation of Physics-Centric Cyberattacks on an Electrical Power Transformer

IEEE Access, 2022
Malware that attack the electrical power grid consist of exploits and operations modules. The exploits are similar to those of traditional malware. These malware hack into an industrial computer and subsequently deploy operational modules.

First results from a 760-GW linear transformer driver module for Z-pinch research

Matter and Radiation at Extremes, 2021
In this paper, the results of tests on a 0.76-TW linear transformer driver (LTD) module for Z-pinch research are presented for the first time. Ten LTD cavities, each generating a 1-MA/90-kV pulse on a matched load, were connected in series with a ...

Data-Driven Optimal Power Flow: A Physics-Informed Machine Learning Approach [PDF]

IEEE Transactions on Power Systems, 2020
This paper proposes a data-driven approach for optimal power flow (OPF) based on the stacked extreme learning machine (SELM) framework. SELM has a fast training speed and does not require the time-consuming parameter tuning process compared with the deep

Improved control effect of pathological oscillations by using delayed feedback stimulation in neural mass model with pedunculopontine nucleus

Brain and Behavior, 2023
Background The role of delayed feedback stimulation in the discussion of Parkinson's disease (PD) has recently received increasing attention. Stimulation of pedunculopontine nucleus (PPN) is an emerging treatment for PD.

Analysis of the strong vertices of $$\Sigma _{c}\Delta D^{*}$$ Σ c Δ D ∗ and $$\Sigma _{b}\Delta B^{*}$$ Σ b Δ B ∗ in QCD sum rules

European Physical Journal C: Particles and Fields, 2023
In this work, we analyze the strong vertices $$\Sigma _{c}\Delta D^{*}$$ Σ c Δ D ∗ and $$\Sigma _{b}\Delta B^{*}$$ Σ b Δ B ∗ using the three-point QCD sum rules under the tensor structures $$i\epsilon ^{\rho \tau \alpha \beta }p_{\alpha }p_{\beta }$$ i ϵ

A switchable terahertz metamaterial absorber between ultra-broadband and dual bands

Frontiers in Physics, 2023
Based on the phase change properties of vanadium dioxide (VO2), we propose a terahertz metamaterial absorber that can be switched flexibly between ultra-broadband and dual bands.
