This paper presents a comprehensive analysis of the current-stress optimization and soft-switching operation isolated bidirectional dual active bridge (DAB) dc-dc converter with unified triple-phase-shift (UTPS) control. On this basis, current-stress-optimized modulation scheme is proposed for DAB, which leads to minimum current stress required transmission power voltage conversion ratio in whole load range. Moreover, full achieved simultaneously. Distinct from previous schemes, optimized...
Emerging findings suggest that compromised cellular bioenergetics and DNA repair contribute to the pathogenesis of Alzheimer's disease (AD), but their role in disease-defining pathology is unclear. We developed a repair-deficient 3xTgAD/Polβ
Brain-derived neurotrophic factor (BDNF) plays important roles in cell survival, neural plasticity, learning, and stress regulation. However, whether the recently found human BDNF Val66Met ( Met ) polymorphism could alter vulnerability remains controversial. More importantly, molecular structural mechanisms underlying interaction between are unclear.

And then, it proved that equally applicable MMC,...
Abstract Background Findings from earlier research have established that insulin resistance (IR) is implicated in atherosclerosis progression, representing a noteworthy risk factor for cardiovascular disease (CVD). Recently, the triglyceride glucose-body mass index (TyG-BMI) has been introduced as straightforward and robust alternative indicator early detection of IR. Nevertheless, there scarcity studies examined capability TyG-BMI predicting incident CVD. Consequently, core objective this...
To acquire high efficiency and reduce electromagnetic interference in wireless high-power charging for electric vehicles (EVs), it is of great importance to realize accurate zero voltage switching angle (ZVSA) control the inverter.

In this paper, suppress power, a current hysteresis comparator adopted, an enhanced phase methodology proposed measure resonant...
Brain-derived neurotrophic factor (BDNF) plays important roles in activity-dependent plasticity processes, such as long-term potentiation, learning, and memory. The recently reported human BDNF Val66Met (BDNF Met ) polymorphism has been shown to lead altered hippocampal volume impaired hippocampal-dependent memory is associated with a variety of neuropsychiatric disorders. There are few studies, however, that investigate the effect on hippocampal-independent processes. A conditioned taste...
Featuring high efficiency, low harmonic distortion, modularity and scalability, the modular multilevel converter (MMC) is particularly suitable for voltage direct current transmission applications. As an advanced control strategy, model predictive (MPC) has advantage of modeling fast dynamic response. It can simultaneously multiple variables through appropriate cost function. The conventional MPC achieve optimal objective by evaluating all candidate switching states MMC; however, with...
Charging electric vehicles wirelessly is promising because of its convenience as well saving charging cables. However, the existing wireless power transfer systems suffer from high resonant peaks and poor efficiency. Therefore, zero voltage switching (ZVS) operation inverter should be achieved especially in power.
