With ensuring food security becoming a priority for the Chinese government, prevalence of off-farm employment (OE) may cast shadow on agricultural productivity. Based data China Family Panel Studies in 2018, Tobit model and threshold effect have been applied to investigate impact productivity efficiency (APE), measured by envelopment analysis (DEA). The result has shown that: (1) OE contributes...

We study spillover e ects of uctuations in US uncertainty. Using monthly panel data from fteen major emerging market economies (EMEs), we show that an unanticipated rise in US stock market uncertainty has negative e ects on their stock prices and exchange rate, increases long-term interest rate spreads, and leads to capital out ows. These negative nancial e ects transmit to the real economy as ...

Traditional use and clinical reports suggest that the culinary herb sage (Salvia officinalis) may be effective for patients with mild to moderate Alzheimer's disease (AD). In this study, we evaluated the effect of a standardized extract from the leaves of S. officinalis (SOE) and its active ingredient rosmarinic acid on Alzheimer amyloid-beta peptide (Abeta)-induced toxicity in cultured rat phe...

This paper aims to explore how CSR has given way to economic growth in China since the start of economic transition and its cultural, his...

هدف از پژوهش حاضر، سنتز، ترکیب متوکسی آمیدو زانتات MAX و نشان‌دارسازی آن با رادیونوکلیید mTc99 به عنوان یک عامل تشخیصی نوین جهت تصویربرداری توموگرافی رایانه‌ای تک فوتونی (SPECT) می­‌باشد. لیگاند فوق واکنش بین دو ماده‌ی کلرواستامید (Chloroacetamide) مشتقات (Xanthate) نسبت‌های مولی معین سنتز شد. سپس فرایند طریق دوشیدن ژنراتور (mTc99Mo/99) روش مستقیم انجام گرفت. این ترتیب که قلع کلرید کاهنده مورد ...

In this paper we first present a novel operator extrapolation (OE) method for solving deterministic variational inequality (VI) problems. Similar to the gradient (operator) projection method, OE updates one single search sequence by subproblem in each iteration. We show that can achieve optimal rate of convergence variety VI problems much simpler way than existing approaches. then introduce sto...
