We prove that the first reduced cohomology with values in a mixing Lp-representation, 1 < p < ∞, vanishes for a class of amenable groups including connected amenable Lie groups. In particular this solves for this class of amenable groups a conjecture of Gromov saying that every finitely generated amenable group has no first reduced lp-cohomology. As a byproduct, we prove a conjecture by Pansu. ...

Recently, the frequency and severity of natural and man-made disasters (extreme events), which have a high-impact low-frequency (HILF) property, are increased. These disasters can lead to extensive outages, damages, and costs in electric power systems. A power system must be built with “resilience” against disasters, which means its ability to withstand disasters efficiently while ensuring the ...
Approximately 1 in 6 conventional, transvenous pacemaker patients experience complications the first 3 years of implant. The Aveir™ VR (Abbott, Abbott Park, IL) is a newly released, single-chamber, ventricular leadless (LP), featuring helix-based fixation mechanism and pre-fixation exploratory electrical mapping capability. By eliminating lead subcutaneous pocket, this alternative to pacemakers...
Key factors that a hospital finance leader should focus on when considering a potential co-management agreement with physicians, in which the physicians are compensated at fair market value, include: Fee structure of the agreement. The quality metrics that will be used. Benchmarking to set appropriate targets for metrics. Historical performance against the metrics. Legal guidelines regarding su...

برنامه ریزی خطی(lp) یک گروه مهم از مسائل بهینه سازی است که در اقتصاد،پژوهش های عملیاتی،مهندسی و حوزه های دیگر علمی مورد استفاده قرار می گیرد.در سال 1985 تانک و هاپفیلد مقاله ای را منتشر کردند و یک روش جدید برای حل مسائل برنامه ریزی خطی با استفاده از شبکه های عصبی بازگشتی ارائه دادند.مدل مذکور پاسخ های یک مسأله ی lp را خیلی سریع به دست می آورد.در سابل 1987 کندی و چوا و بعدها مآ و شنبلت مدل های ب...
Sphingosine 1-phosphate (S1P) exerts diverse physiological actions by activating its cognate G protein-coupled receptors. Five S1P receptors have been identified in mammals: LP(B1)/EDG-1, LP(B2)/H218/AGR16/EDG-5, LP(B3)/EDG-3, LP(B4)/NRG-1/EDG-8, and LP(C1)/EDG-6. One of these receptors, LP(B1), has recently been shown to be essential for mouse embryonic development. Here we disrupted the lp(B3...
