Based on the integral theory, tension-free placement of a mid-urethral sling (MUS) for female stress urinary incontinence (SUI) has gained substantial popularity owing to the ease of the procedure and its effectiveness. Published series with long-term follow-up show continence rates after the MUS procedure ranging from 70% to 80%. Complication rates after MUS procedures are usually low. This re...
Optical and near-infrared (near-IR) observations of the Type Ic supernova (SN Ic) 2004aw are presented, obtained from −3 to +413 days with respect to the B-band maximum. The photometric evolution is characterised by a comparatively slow postmaximum decline of the light curves. The peaks in redder bands are significantly delayed relative to the bluer bands, the I-band maximum occurring 8.4 days ...
In its basic form, a variability model describes the variations among similar artifacts from a structural point of view. It does not capture any information about when these variations occur or how they are related to each other in time. This abstraction becomes problematic as soon as time-related aspects become essential for the modeling purpose, e.g., when providing long-term support for a pr...
Aptamers, and the selection process known as Systematic Evolution of Ligands by Exponential Enrichment (SELEX) used to generate them, were first described more than twenty years ago. Since then, there have been numerous modifications to the selection procedures. This review discusses the use of modified bases as a means of enhancing serum stability and producing effective therapeutic tools, as ...
کاربرد موفقیت آمیز مدل های بارش – رواناب، به چگونگی واسنجی پارامترهای آنها بستگی دارد. مدل های مفهومی بارش - رواناب، عموماً دارای پارامترهای زیادی هستند که نمی توان آنها را به صورت مستقیم برآورد نمود و لازم است که آنها را در طول واسنجی مدل تخمین زد. هدف از انجام واسنجی، یافتن مقادیر آن سری از پارامترهایی است که باعث بهینه شدن معیارهای ارزیابی کارایی مدل می شوند. دو روش دستی و خودکار برای واسنجی ...
The recent success of distributed and dynamic infrastructures for knowledge sharing has raised the need for semiautomatic/automatic ontology evolution strategies. Ontology evolution is generally defined as the timely adaptation of an ontology to changing requirements and the consistent propagation of changes to dependent artifacts. In this article, we present an ontology evolution approach in t...

Chemically Consistent Evolution of Galaxies on Cosmological Timescales and the Dla Galaxy Population
We describe the evolution of galaxies in a chemically consistent way accounting for the increasing initial metallicity of successive generations of stars. The enrichment of various types of model galaxies is compared with Damped Lyα (= DLA) abundances over the redshift range from z ∼ 0 through z > 4.4. We discuss properties and composition of the galaxy population giving rise to DLA absorption....
Advanced observational facilities allow to trace back the chemical evolution of the Universe, on the one hand, from local objects of different ages and, secondly, by direct observations of redshifted objects. The chemical enrichment serves as one of the cornerstones of cosmological evolution. In order to understand this chemical evolution in morphologically different astrophysical objects model...
Long Term Evolution (LTE) is a standard for high speed communication in wireless networks. It is developed by 3 Generation Partnership Project (3GPP). One of the goals of LTE was to increase the capacity of wireless networks so that communication can be performed at high speeds. The second goal was to redesign and simplify the architecture of the network so as to conform to an Internet Protocol...
