In a diffuse sound field, prior research has established that a secondary source can theoretically achieve perfect cancellation at an error microphone in the far field of the secondary source. However, the sound pressure level is generally only reduced in a small zone around the error sensor, and at a distance half of a wavelength away from the error sensor, the averaged sound pressure level wi...
Mitochondria in cells comprise a tubulovesicular reticulum shaped by dynamic fission and fusion events. The multimeric dynamin-like GTPase Drp1 is a critical protein mediating mitochondrial division. It harbors multiple motifs including GTP-binding, middle, and GTPase effector (GED) domains that are important for both intramolecular and intermolecular interactions. As for other members of the d...
Patient classification through feature selection (FS) based on gene expression data (GED) has already become popular to the research communities. T-test is the well-known statistical FS method in GED analysis. However, it produces higher false positives and lower accuracies for small sample sizes or in presence of outliers. To get rid from the shortcomings of t-test with small sample sizes, SAM...
Large deformation control of surrounding rock in deep soft-broken coal roadway has always been a key scientific and technological problem restricting the resources exploitation. Taking gob-side entry driving (GED) isolated face under as research object, prominent difficulties were clarified. Through numerical simulation, evolution laws deviatoric stress plastic zone GED different pillar widths ...
In this study, the volatility of two Asian stock markets, Bursa Malaysia and Singapore Exchange, is estimated. The analysis used data on daily closing prices indices respective markets between July 1, 2019 August 31, 2020. sample split into subsample periods: Pre-COVID-19 pandemic during COVID-19 pandemic. We estimated a standard GARCH, GARCH-M, TGARCH, EGARCH PGARCH model for each subsample. c...
در این مقاله یک مدل ریاضی برای مسئله سیستم تولیدی همکارانه ساخت بر اساس سفارش با رعایت انصاف تخصیص بارهای تولید طراحی شده است. اهداف اصلی مدل، کمینهسازی هزینههای کل و حداکثر استفاده از منابع بهمنظور عادلانه شرایط عدمقطعیت کنترل پارامترهای غیرقطعی روش برنامهریزی فازی شده نتایج نشان میدهد افزایش نرخ عدمقطعیت، مییابد. ازآنجاکه ظرفیت کارخانهها ثابت است، مقدار تقاضا، هر کارخانه نیز میی...
The molecular structure of 1-methyl-1-silacyclohexane 3 has been determined by gas electron diffraction (GED). The conformational preference of the methyl group was studied experimentally in the gas phase (GED) and in solution (low-temperature (13)C NMR) and by quantum chemical calculations (HF, MP2, and B3LYP with 6-31G basis sets and mPW1PW91/6-311G(2df,p)). Both experimental methods result i...
