Qualitative Analysis of Electrical Mismatch Losses in Photovoltaic Devices

open access: green, 2013
This paper analyzes qualitatively the effect that occurs in a photovoltaic device (PV) with electrical mismatch losses. Mathematical models of PV cells are used by means of an open source simulation tool for electronic circuits able to simulate the electrical performance of PV modules and arrays both under normal generation as well as under electrical ...

A Scalable Hierarchical Dynamic PV Array Reconfiguration under Partial Shading

open access: yesEnergies, 2023
Photovoltaic (PV) arrays are often affected by partial shading (PS), which can significantly reduce their power output. Dynamic reconfiguration is a promising technique for mitigating the negative effects of PS by adjusting the electrical connections of ...

Relaying systems with reciprocity mismatch : impact analysis and calibration [PDF]

open access: yes, 2020
Cooperative beamforming can provide significant performance improvement for relaying systems with the help of the channel state information (CSI). In time-division duplexing (TDD) mode, the estimated CSI will deteriorate due to the reciprocity mismatch ...

Energy Acquisition of Solar-Powered Joint-Wing Aircraft Considering Mismatch Power Loss

open access: yesEnergies, 2021
Solar-powered aircraft can perform long-term flights with clean solar energy. However, the energy derived from solar irradiation is influenced by the time of year and latitude, which limits the energy acquisition ability of solar aircraft with a straight-

Prime editing efficiency and fidelity are enhanced in the absence of mismatch repair

open access: yesNature Communications, 2022
Prime Editing is a versatile genome engineering tool. Here, the authors identify the DNA repair pathway known as mismatch repair as inhibitory for Prime Editing, thus, loss of mismatch repair enhances the efficiency of Prime Editing.

Information Loss Associated with Imperfect Observation and Mismatched Decoding [PDF]

open access: yesFrontiers in Computational Neuroscience, 2011
We consider two types of causes leading to information loss when neural activities are passed and processed in the brain. One is responses of upstream neurons to stimuli being imperfectly observed by downstream neurons. The other is upstream neurons non-optimally decoding stimuli information contained in the activities of the downstream neurons.
