Physics of the power corrections in QCD [PDF]

Surveys in High Energy Physics, 2000
We review the physics of the power corrections to the parton model. In the first part, we consider the power corrections which characterize the infrared sensitivity of Feynman graphs when the contribution of short distances dominates. The second part is devoted to the hypothetical power corrections associated with nonperturbative effects at small ...

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 ...

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.

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.

Analysis of the D-wave $$\Sigma $$ Σ -type charmed baryon states with the QCD sum rules

European Physical Journal C: Particles and Fields, 2023
We construct the $$\Sigma $$ Σ -type currents to investigate the D-wave charmed baryon states with the QCD sum rules systematically. The predicted masses $$M=3.35^{+0.13}_{-0.18}\,\textrm{GeV}$$ M = 3 .

Power Dynamics in Physics

, 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

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.
