Performance of PV array configurations under dynamic partial shadings

EPJ Photovoltaics, 2023
The partial shading effect (PSE) is responsible for most power losses in a photovoltaic (PV) system. By modifying the interconnections between PV modules, called PV array reconfiguration, it is possible to improve the power output under partial shading ...

Analysis of the Problems Occurred Due to Partial Shading of Solar Photovoltaic Array and Probable Solutions [PDF]

, 2019
A solar panel is made up of solar cells where semiconductors made to react and give us a potential difference when solar energy falls on it. However, due to the internal and external interferences, many problems are faced by solar panels, like dust ...

Meson Exchange Currents in Kaon Scattering on the Lightest Nuclei [PDF]

, 1997
The K^+ scattering on the lightest nuclei, d, 3He and 4He is studied in the framework of multiple scattering theory. Effects from MEC tied to the K^+N-->KNpi reaction are evaluated.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Coronal heating in coupled photosphere-chromosphere-coronal systems: turbulence and leakage [PDF]

, 2011
Coronal loops act as resonant cavities for low frequency fluctuations that are transmitted from the deeper layers of the solar atmosphere and are amplified in the corona, triggering nonlinear interactions.
