The ability to quantify in vivo femoro-tibial relations in the knee holds great advantage to further patient care. There is little consensus on the optimal weight-bearing environment and measurement method for MRI assessment of in vivo knee kinematics. This study set out to establish the optimal method of measuring femoro-tibial relations in an upright, weight-bearing environment in normal indi...
To improve the primary frequency response in future low-inertia hybrid power system a fuzzylogic based frequency controller (FFC) for wind farms augmented with energy storage systems(wind-storage system) and intelligent PV farms for the frequency stabilization is proposed inthis paper. Using system frequency deviations the proposed controller provides bidirectionalreal p...
There is mounting evidence that neutrinos undergo fast flavor conversion (FFC) in core-collapse supernova (CCSN). In this letter, we investigate the roles of stellar rotation on occurrence FFC by carrying out axisymmetric CCSN simulations with full Boltzmann neutrino transport. Our result suggests electron lepton number (ELN) angular crossings, which are necessary and sufficient condition to tr...
In this paper, a grid connected microgrid with multiple inverter-based distributed generators (DGs) is considered. DG in FFC mode regulates the microgrid as a controllable load from the utility point of view as long as its output is within the capacity limit. The transition mode causes a change in frequency of microgrid due to the loss of power transferred between main grid and microgrid. Frequ...
یک ریزشبکه قسمتی از شبکه توزیع است که از تعدادی واحد تولید پراکنده (dg) و بارهای متصل به آن تشکیل شده است و می تواند در دو حالت متصل به شبکه (مود موازی) و یا مستقل از آن (مود جزیره ای) عمل کند. طیف فن آوری-های مطرح در ساختار dgهای ریزشبکه بسیار گسترده است و برقراری اتصال بسیاری از این فن آوری ها با شبکه برق، نیازمند واسط های اینورتری است (ei-dg). در این میان و مشابه سیستم های قدرت مرسوم، یکی ...
Several recent numerical studies have examined the effects of neutrino neutral-current scattering on fast flavor conversion (FFC). Those are in apparent conflict, with some finding enhancement and others suppression. The ones that report all use homogeneous models, we discuss detail self-consistency issues they face as a result. We reproduce scattering-enhanced FFC our own calculations, showing...
[1] Floor-Fractured Craters (FFCs) are a class of lunar craters characterized by anomalously shallow floors cut by radial, concentric, and/or polygonal fractures; additional interior features are moats, ridges, and patches of mare material. Two formation mechanisms have been hypothesized—floor uplift in response to shallow magmatic intrusion and sill formation, and floor shallowing in response ...
OBJECTIVE To study food patterns assessed using scores of consumption and their relationship with serum total cholesterol (TOTAL-C), low density lipoprotein-cholesterol (LDL-C) and high density lipoproteins (HDL-C) concentration in the population of the metropolitan area of São Paulo, Brazil. METHODS Data on food frequency consumption (FFC), serum lipids, and other covariates were available f...
The accurate monitoring of forest cover and its changes are essential for environmental change research, but current satellite products coverage carry many uncertainties. This study used 30-m Landsat-8 data, aggregated 1-m GaoFen-2 (GF-2) images to construct the training samples multiple machine learning algorithms (MLAs) estimate fractional (FFC) in China’s Three North Region (TNR). In this st...
With the increase in obesity worldwide, its associated comorbidities, including nonalcoholic steatohepatitis (NASH), have become a public health problem that still lacks effective therapy. We have previously reported that mixed-lineage kinase 3-deficient (MLK3-deficient) mice are protected against diet-induced NASH. Given the critical need to identify new therapeutic agents, we sought to examin...
