در این مقاله فرمول بندی بهینه مدل bcs با استفاده از تابع توزیع احتمال هم دما ارائه و تأثیر افت و خیز های آماری بر رفتار ترمودینامیکی هسته های بررسی شده است. در ابتدا مقدار میانگین پارامتر گاف و سپس انرژی، آنتروپی و ظرفیت گرمایی محاسبه شده اند. نتایج حاصله با نتایج مدل استاندارد bcs و نتایج روش تقریب مسیر ایستایی باضافه تقریب فاز کاتوره ای(spa+rpa) مقایسه شده اند. نشان داده ایم که رفتار ظرفیت گر...
A marked increase in the number of basophilic cells (BCs) was found in the bronchoalveolar lavage (BAL) fluids from the patients with bronchial asthma and idiopathic pulmonary fibrosis (IPF). Histochemical analysis revealed that basophils were the major components of BCs in asthmatic patients, while formalin-insensitive BCs, which are presumed to be connective tissue mast cells, were observed i...
Background and study aims Bile cast syndrome (BCS) is a complication of orthotopic liver transplantation (OLT). It occurs in 4 % to 18 % of OLT recipients and can present as cholangitis and graft damage or loss. Twenty-two percent of patients with BCS require repeat OLT. The diagnosis and management of BCS can be challenging. Our aim is to share our experience with BCS and to briefly review the...
Effect of diameter of pre-ovulatory follicle (POF) and body condition score (BCS) of buffaloes on pregnancy rate following ovsynch-TAI were studied in 100 post-partum anestrus buffaloes. The size of POF was determined through sonography on day 10 of protocol. BCS of buffaloes were estimated at the time of AI. Pregnancy was con rmed per-rectally on day 60 post-AI. Pregnancy rate in buffaloes wi...
Abstract. In the [BCS] paper the theory of superconductivity was developed for the BCS model, in which the (instantaneous) interaction is only between fermions of opposite momentum and spin. Such model was analyzed by variational methods, finding that a superconducting behavior is energetically favorable. Subsequently it was claimed that in the thermodynamic limit the BCS model is equivalent to...
Backchannels (BCs) are short vocal and visual listener responses that signal attention, interest, and understanding to the speaker. Previous studies have investigated BC prediction in telephone-style dialogs from prosodic cues. In contrast, we consider spontaneous face-to-face dialogs. The additional visual modality allows speaker and listener to monitor each other’s attention continuously, and...
For the Cooper/BCS model interaction in superconductors (SCs) it is shown: a) how BCS-Bose crossover picture transition temperatures Tc, defined self-consistently by both the gap and fermion-number equations, require unphysically large couplings to differ significantly from the Tc of ordinary BCS theory defined without the number equation since here the chemical potential is assumed equal to th...
Groundwater microbial community samples are traditionally collected using pumping techniques optimized for groundwater chemistry assessment although the impact of groundwater pumping parameters on apparent bacterial community structures (BCS) is not really known. We therefore studied the impact of pumping lift, flow regime and tubing material on BCS, which were analyzed by terminal-restriction ...
Canine obesity is a prevalent disease, but many owners are unaware of it, partly due to misperception of their dog's body shape. Body condition scoring (BCS) is a simple method of assessing body composition, but whether it can reduce owner misperception is unclear. Our aim was to determine the effect of a BCS system on owners' ability to estimate the body condition of their dog. Information fro...
BACKGROUND Despite rising breast cancer incidence and mortality rates, breast cancer screening (BCS) rates among women in Qatar remain low. Previous studies indicate the need to better understand the many complex beliefs, values, and attitudes that influence Arab women's health seeking behavior for the development of culturally appropriate and effective intervention strategies to address breast...
