Maximum Power Extraction from a Partially Shaded PV System Using an Interleaved Boost Converter

open access: yesEnergies, 2018
The partially shaded photovoltaic (PSPV) condition reduces the generated power and contributes to hot spot problems that may lead to breakdown of shaded modules. PSPV generates multiple peak, one global one and many other local peaks.

Effects of mismatched transmissions on two-mode squeezing and EPR correlations with a slow light medium [PDF]

open access: yes, 2005
We theoretically discuss the preservation of squeezing and continuous variable entanglement of two mode squeezed light when the two modes are subjected to unequal transmission.

Loss of DNA mismatch repair proteins in prostate cancer

open access: yesMedicine, 2020
Abstract Recent studies have suggested an increased risk of prostate cancer in men with Lynch syndrome driven by germline mutations in mismatch repair (MMR) genes. However, the incidence and clinical implication of MMR deficiency in sporadic prostate cancers remain poorly understood.

Power generation characteristics of vertical bifacial photovoltaic arrays in heavy snow regions

open access: yesEPJ Photovoltaics
Conventional tilted photovoltaic systems often experience reduced electricity generation and potential damage due to snow accumulation. In contrast, vertical bifacial photovoltaic systems demonstrate greater resilience against snow-related damage, making

Power enhanced solar PV array configuration based on calcudoku puzzle pattern for partial shaded PV system

open access: yesHeliyon, 2023
The power output of solar photovoltaic systems can be affected by environmental factors, such as partial shading. This can lead to a decrease in the power conversion rate of the system.

Tunable n-path notch filters for blocker suppression: modeling and verification [PDF]

open access: yes, 2013
N-path switched-RC circuits can realize filters with very high linearity and compression point while they are tunable by a clock frequency. In this paper, both differential and single-ended N-path notch filters are modeled and analyzed.
