A high-precision calculation of the 7s-8s parity-nonconserving ~PNC! transition amplitude in francium, based on a relativistic all-order method, is presented. Our values for the PNC amplitudes in Fr and Fr are EPNC515.41(17) and 14.02(15), respectively, in units 10 iueua0(2QW /N), where QW is the weak charge and N is the neutron number. Spin-dependent contributions to the PNC amplitude are calc...

BACKGROUND Previous studies have demonstrated that prenatal care (PNC) has an effect on women's breastfeeding practices. This study aims to examine the influence of adequacy of PNC initiation and services use on breastfeeding practices in Canada. METHODS Data for this secondary analysis was drawn from the Maternity Experiences Survey (MES), a cross sectional, nationally representative study t...

Using nystatin-perforated patch-clamp and whole cell recording, we tested the hypothesis that K(ATP) channels contribute to resting conductance of rat descending vasa recta (DVR) pericytes and are modulated by vasoconstrictors. The K(ATP) blocker glybenclamide (Glb; 10 microM) depolarized pericytes and inhibited outward currents of cells held at -40 mV. K(ATP) openers pinacidil (Pnc; 10 microM)...

We have developed electroosmotic pumps (EOPs) fabricated from 15-nm-thick porous nanocrystalline silicon (pnc-Si) membranes. Ultrathin pnc-Si membranes enable high electroosmotic flow per unit voltage. We demonstrate that electroosmosis theory compares well with the observed pnc-Si flow rates. We attribute the high flow rates to high electrical fields present across the 15-nm span of the membra...

Physical-layer network coding (PNC) is a communications paradigm that exploits overlapped transmissions to boost the throughput of wireless relay networks. A high point of PNC research was a theoretical proof that PNC that makes use of nested lattice codes could approach the information-theoretic capacity of a two-way relay network (TWRN), where two end nodes communicate via a relay node. The c...

This paper investigates various subtleties of applying linear physical-layer network coding (PNC) with q-level pulse amplitude modulation (q-PAM) in two-way relay channels (TWRC). A critical issue is how the PNC system performs when the received powers from the two users at the relay are imbalanced. In particular, how would the PNC system perform under slight power imbalance that is inevitable ...

Objective: Stress urinary incontinence (SUI), the leakage of urine due to an increase in abdominal pressure, affects 30% of women over the age of 40. Childbirth is the primary risk factor for SUI since the child’s head passing through the birth canal can injure the EUS and the nerve that innervates it, the pudendal nerve (PN). Animal models with combined EUS [vaginal distension (VD)] and PN cru...

The perinucleolar compartment (PNC) is a subnuclear body that forms in cancer cells. In vivo analyses using human tumor tissues demonstrate a close correlation between PNC prevalence and disease progress in colorectal carcinoma, and a high PNC prevalence is associated with poor patient outcome. These findings are consistent with previous observations in breast cancer and cancer cell lines in vi...
