Power Dynamics in Physics

open access: yes, 2022
The purpose of this white paper is to describe how unfair power dynamics related to various aspects of identity -- race, gender identity, gender expression, sexual orientation, and ability status -- operate in physics settings and offer concrete steps that one can take to make our discipline more equitable and just.

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

open access: yesBrain 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.

Wind Farm Modeling with Interpretable Physics-Informed Machine Learning

open access: yesEnergies, 2019
Turbulent wakes trailing utility-scale wind turbines reduce the power production and efficiency of downstream turbines. Thorough understanding and modeling of these wakes is required to optimally design wind farms as well as control and predict their ...

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

open access: yesEuropean 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

Measurement of (n,α) cross section for set of structural material isotopes

open access: yesEPJ Web of Conferences, 2017
A novel spectrometer was developed and used to measure the cross section for the (n,α) reaction at IPPE. Direct measurements of the α-particles yield from solid isotopic pure targets of 50, 52 and 53 chromium, 54 and 57 iron, 60 nickel, and 64 zinc were ...

Closed-loop controller based on reference signal tracking for absence seizures

open access: yesScientific Reports, 2022
Absent epilepsy is a kind of refractory epilepsy, which is characterized by 2–4 Hz spike and wave discharges (SWDs) in electroencephalogram. Open-loop deep brain stimulation (DBS) targeting the thalamic reticular nucleus (TRN) is an effective method to ...

The physics of electric power systems

open access: yesEPJ Web of Conferences, 2013
The article describes electric power systems from a physicist’s point of view. In contrast to common introductory textbooks on power systems, the emphasis is on the physical design, that is the material selection and the choice of the geometrical shape ...
