Synchronizers play a key role in multi-clock domain systems on chip. Designing reliable synchronizers requires estimating and evaluating synchronizer parameters (resolution time constant) and (metastability window). Typically, evaluation of these parameters has been done by empirical rules of thumb or simple circuit simulations to ensure that the synchronizer MTBF is sufficiently long. This pap...

BACKGROUND Nonattendance for scheduled appointments disturbs the effective management of pediatric pulmonary clinics. We hypothesized that the reasons for non-attendance and the necessary solutions might be different in pediatric pulmonary medicine than in other pediatric fields. We therefore investigated the factors associated with nonattendance this field in order to devise a corrective strat...

Background Specific growth factors and feeder layers seem to have important roles in in vitro embryonic stem cells (ESCs) differentiation. In this study,the effects of bone morphogenetic protein 4 (BMP4) and mouse embryonic fibroblasts (MEFs) co-culture system on germ cell differentiation from mouse ESCs were studied. MaterialsAndMethods Cell suspension was prepared from one-day-old embryoid bo...

Objective(s): Studies have confirmed that microgravity, as a mechanical factor, influences both differentiation and function of mesenchymal stem cells. Here we investigated the effects of simulated microgravity on neural differentiation of human adipose-derived stem cells (ADSCs). Materials and Methods:We have used a fast rotating clinostat (clinorotation) to simulate microgravity condition. R...

this dissertation has six chapter and tree appendices. chapter 1 introduces the thesis proposal including description of problem, key questions, hypothesis, backgrounds and review of literature, research objectives, methodology and theoretical concepts (key terms) taken the literature and facilitate an understanding of national security, national interest and turkish- israeli relations concepts...

BACKGROUND Nonmelanoma skin cancers (NMSC) constitute the largest group of skin cancers. In this study, NMSCs were analyzed retrospectively. METHODS Between June 2013 and March 2017, demographics and comorbidities of patients underwent reconstructive surgery for NMSC; their risk factors, types, diameters, differentiation, localizations, follow-up times, treatment methods and complications we...

this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
