Tracking data provenance (or lineage) has become increasingly important in many large-scale applications. Till now, a few methods have been proposed to record data provenance. However, most of them mainly focus on deterministic databases except Trio style lineage that aims at probabilistic databases. Processing provenance upon probabilistic database is even challenging because of the exponentia...

Knowledge of the spatial distribution and evolution of embedded charge in thin dielectric materials has important applications in semiconductor, high-power electronic device, high-voltage DC power cable insulation, high-energy and plasma physics apparatus, and spacecraft industries. Knowing how, where, and how much charge accumulates and how it redistributes and dissipates can predict destructi...

This study investigated the infection of Perkinsus beihaiensis (Perkinsozoa) in the oyster Crassostrea rhizophorae, both from a long-line cultivation system and from a nearby intertidal zone of mangrove, both in the state of Bahia, northeastern Brazil. The collections were performed in October and November 2012, and in January 2013. The oysters (n = 300) were measured, examined macroscopically ...

Abstract Introduction People with parkinsonism (PwP) are a highly heterogeneous group and the condition encompasses spectrum of motor nonmotor symptoms which variably emerge manifest across disease course, fluctuate over time negatively impact quality life. Whilst is not directly result ageing, it that mostly affects older people, who may also be living frailty multimorbidity. This study aims t...

Development of intrinsic electric charges at solid/liquid interfaces is still not fully understood and may generate large industrial damages by electrostatic discharges due to flow electrification. The pressure-wave-propagation (PWP) method used study in flowing conditions. Experimental results are shown with aluminum, brass, copper or pressboard contact demineralized water, salted glycerol min...

سابقه و هدف: ورود گونه­­ های ماهی مهاجم دراکوسیستم ­های آبی، سبب بروز انواع اثرات منفی اکولوژیکی اقتصادی-اجتماعی می ­­شود. اولین گام در تجزیه تحلیل مخاطرات ناشی از گونه­ غیر­بومی، شناسایی خطر است بر این اساس ابزارهای متعددی برای ارزیابی خطرات تهاجمی غیربومی به منظور پشتیبانی تصمیم گیرندگان گونه ­­ها ایجاد شده است. هدف پژوهش قدرت تیلاپیای شکم قرمز (Coptodon zillii) حوضه آبریز تالاب شادگان (حوضه‌...

Long-term (13 years) impact of organic and conventional farming on soil physical properties was evaluated under a rice (Oryza sativa L.) – wheat (Triticum aestivum cropping system in sandy clay loam at New Delhi. The treatments included unfertilized control (T1), conventionally managed (T2) five (T3: FYM @ 10 t/ha to wheat, T4: SGM for LGLM T5: + BGA Azotobacter T6: T7: wheat). application amen...

در آشکار‌ساز CMS نسبت‌های انشعاب بوزون هیگز مدل استاندارد به جفت‌‌های J/ψ(1S) و cc ترتیب برابر 2-10×1/8 2-10×2/89 اندازه‌گیری شده است. لحاظ نظری یکی از سناریوهای ممکن برای تولید مستقیم این است که آغاز جفت واپاشی نماید سپس مرحله‌ی بعد هر یک کوارک‌های c طور مزون ترکش کنند. بر اساس سناریو مقاله بطریق کوارک‎های با استفاده نظریه اختلال مکانیک کوانتومی رنگ (pQCD) نظر گرفتن حالت‌های قطبش طولی عرضی محا...
