Although recent studies have attempted to dispel the confusion that exists in regard definition, analysis and interpretation of interaction genetics, there still remain aspects are poorly understood by non-statisticians. After a brief discussion definition gene-gene interaction, main part this study addresses fundamental meaning statistical its relationship measurement scale, disproportionate sample sizes cells two-way table gametic phase disequilibrium.
The limited oxidation stability of ether solvents has posed significant challenges for their applications in high-voltage lithium metal batteries (LMBs). To tackle this issue, the prevailing strategy either adopts a high concentration fluorinated salts or relies on highly solvents, which will significantly increase manufacturing cost and create severe environmental hazards. Herein, an alternative sustainable salt engineering approach is proposed to enable utilization dilute electrolytes...
Abstract The limited oxidation stability of ether solvents has posed significant challenges for their applications in high‐voltage lithium metal batteries (LMBs). To tackle this issue, the prevailing strategy either adopts a high concentration fluorinated salts or relies on highly solvents, which will significantly increase manufacturing cost and create severe environmental hazards. Herein, an alternative sustainable salt engineering approach is proposed to enable utilization dilute...
Unbalanced grid faults are very harmful to the network operation. Distributed static synchronous compensator (D-STATCOM) can help support voltage by injecting reactive power into inductive grid. However, this approach turns be ineffective for a low-voltage grid, where impedance is mainly resistive. In article, dynamic equalization control (DVEC) scheme proposed suppress negative sequence voltage, and therefore, reduce unbalance during in resistive network. This effect achieved through...
For the distributed static synchronous compensator (D-STATCOM), sequence extraction (SE) is generally necessary in dual current controls (DSCCs) based on double reference frame (SRF), when D-STATCOM suffers from unbalanced grid voltage. However, SE will narrow down control bandwidth and increase complexity. In this article, influences of not using DSCC are analyzed. On basis, a self-decoupled (SDDSCC) proposed. Accordingly, novel parameter design method SDDSCC also The can achieve two types...
Virtual synchronous generator (VSG) control enables grid-connected converter to behave in a similar way with the (SG), which is helpful enhance stability of power system. However, coupling between active loop (APL) and reactive (RPL) has negative effect on dynamic performance system even lead instability. A thorough inquiry into made this paper. Analysis indicates that stems from output voltage. Nevertheless, could not be thoroughly solved by virtual inductor. And, implementation inductor...
Critical illness insurance (CII) in China was introduced to protect high-cost groups from health expenditure shocks for the purpose of mutual aid. This study aimed evaluate impact CII on burden central rural China. Data were extracted basic medical (BMI) hospitalization database Xiantao City January 2010 December 2016. A total 77,757 records included our analysis. The out-of-pocket (OOP) expenses and reimbursement ratio (RR) two main outcome variables. Interrupted time series analysis with a...
The microinjection is generally performed on commercial pump using a nitrogen gas-holder as pressure supply. However, the has some problems in picoliter-scale injection due to instability of source, and success rate varies significantly across different operators. In this paper, high-precision, pressure-driven for sub-picoliter scale quantitative developed. This new pumping system capable generating wide range positive negative with high resolution by connecting buffer tank gas passage...
In a high-power three-phase voltage source inverter, step-up transformer may be used at the output of LC filter to achieve higher voltage, improve electromagnetism compatibility and serve as inductor under parallel operation. However, standalone operation, performance inverter is degraded since feedback control does not include transformer. This paper proposes multiple paths load current full feedforward designed in discrete time domain inverter. The proposed controller has concise...
Developing communicative competence plays a very important role in Chinese college students’ English learning. This study investigates how well the students do using to communicate with others help of questionnaires, which may them find out some practical strategies overcome their difficulties communicating English. After careful analysis means subjects’ scores, causes for weak are found out. They lack enthusiasm communicate, related cultural background knowledge English-speaking countries,...
A novel and simple control method is proposed in this paper to improve the operation performance of distribution static synchronous compensator (D-STATCOM) under unbalanced operating condition. The functional block for extracting positive negative sequence components eventually avoided by employing dual current regulators positive- negative-rotating frames. notch filter be added direct axis rotating frame vanish third harmonic output caused second DC-link voltage as well disturbance...
The shunt active power filter (SAPF) based on three-leg voltage source converter is widely used to compensate the harmonic currents caused by nonlinear loads of grid. However, when are unbalanced, grid compensated SAPF still unbalanced and distorted even an accurate current detection method adopted. reason that compensates grid, DC-link will contain second-order which has influence d-axis reference SAPF's control loop. Then output extra third-order fundamental negative sequence currents,...
