Research of Zero Sequence Current of Parallel System of PWM Rectifier

Gong-kuang zidonghua, 2012
Taking two-level parallel system of PWM rectifier as example, the paper analyzed cause of zero sequence circulation in parallel module: the circulation is generated by difference of duty cycle of zero sequence current of two modules; generation of the ...

The contribution of viral genotype to plasma viral set-point in HIV infection.

PLoS Pathogens, 2014
Disease progression in HIV-infected individuals varies greatly, and while the environmental and host factors influencing this variation have been widely investigated, the viral contribution to variation in set-point viral load, a predictor of disease ...

Influence of cementless hip stems on femoral cortical strain pattern depending on their extent of porous coating [PDF]

, 2012
The extent of porous coating of cementless total hip stems is held responsible for radiological periprosthetic changes, the rate of thigh pain, and even its long-term success.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1

Molecular Oncology, EarlyView.
Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

Optimizing production scheduling of steel plate hot rolling for economic load dispatch under time-of-use electricity pricing [PDF]

, 2017
Time-of-Use (TOU) electricity pricing provides an opportunity for industrial users to cut electricity costs. Although many methods for Economic Load Dispatch (ELD) under TOU pricing in continuous industrial processing have been proposed, there are still ...

PARP inhibitors elicit distinct transcriptional programs in homologous recombination competent castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
PARP inhibitors are used to treat a small subset of prostate cancer patients. These studies reveal that PARP1 activity and expression are different between European American and African American prostate cancer tissue samples. Additionally, different PARP inhibitors cause unique and overlapping transcriptional changes, notably, p53 pathway upregulation.

A new analytical approach for describing fatigue load sequence effects

Heron, 2020
Load sequence effects in fatigue crack growth, such as retardation and acceleration due to a large overload (OL) and underload (UL), can dramatically change the (remaining) fatigue life. These effects can be determined using analytical and numerical tools, often trading accuracy for a steep increase in required calculation time.
