Quantifying Incomplete Zero-Voltage Switching Losses Using Equivalent HardSwitching Losses
With fast switching wide band-gap semiconductors conquering high-power application, zerovoltage switching (ZVS) topologies are crucial to increase converter efficiency by minimizing switching losses. However, ZVS criteria cannot always be fulfilled in the entire operating range of the converter. In this case, the converter enters incomplete ZVS (iZVS).

Molecular Oncology, EarlyView.This review summarizes the transcription factors, repressive chromatin‐modifying complexes, and epigenetic mechanisms that control fetal hemoglobin repression. Notably, many regulators of γ‐globin silencing also function in transcriptional and epigenetic networks that drive cancer, highlighting opportunities to translate advances in hemoglobinopathy ...

Auxiliary Inverter with Zero-current Soft Switching DC/DC Converter Input
机车电传动, 2014 An auxiliary inverter with zero-current soft switching DC/DC converter input was proposed. Two-stage transformer circuit structure was adopted, the front part of which was DC/DC converter, and the rear part of which was three-phase inverter circuit. Zero-

PANoptosis in the pathogenesis of myelodysplastic syndromes
Molecular Oncology, EarlyView.PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Effects of Hearing Loss on Maintaining and Switching Attention
Acta Acustica united with Acustica, 2018 The ability to intentionally control attention based on task goals and stimulus properties is critical to communication in many environments. However, when a person has a damaged auditory system, such as with hearing loss, perceptual organization may also be impaired, making it more difficult to direct attention to different auditory objects in the ...

Molecular Oncology, EarlyView.This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Long Memory with Markov-Switching GARCH [PDF]
The paper considers the Markov-Switching GARCH(1,1)-model with time-varying transition probabilities. It derives sufficient conditions for the square of the process to display long memory and provides some additional intuition for the empirical ...

ADP‐ribosylation: An emerging regulator of the epigenome
Molecular Oncology, EarlyView.ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...

Estimation of Markov regime-switching regression models with endogenous switching [PDF]
Following Hamilton (1989), estimation of Markov regime-switching regressions nearly always relies on the assumption that the latent state variable controlling the regime change is exogenous.
