In large persistent object systems it is possible to have many million (or eventually billion or more) objects in existence. These objects must be managed to enable their eeective and convenient use. At the heart of this management problem is the structure which maintains information about the objects and provides services on the objects using the information it maintains. We refer to this stru...
برای دستیابی به مزیت رقابتی در شرایط عدماطمینان که آن تغییر ضروری است، یکی از چالشهای بزرگ سازمانها کاهش ریسک طریق ایجاد زنجیرههای تأمین تابآور است. تابآوری زنجیره تأمین توانایی مقابله با اختلال اشاره دارد یک رویداد غیرقابلپیشبینی بوده و دارای منابع داخلی خارجی مختلفی ازجمله بلایای طبیعی ریسکهای عملیاتی پژوهش حاضر شبیهسازی توسط نرمافزار ارنا زنجیره سنگ ساختمانی «کارخانه سنگبری آسم...
The swap mechanism allows an operating system to work with more memory than available RAM space, by temporarily flushing some data to disk. However, the system sometimes ends up spending more time swapping data in and out of disk than performing actual computation. This state is called thrashing. Classical strategies against thrashing rely on reducing system load, so as to decrease memory press...
PURPOSE To compare the abilities of scanning laser polarimetry (SLP), optical coherence tomography (OCT), short-wavelength automated perimetry (SWAP), and frequency-doubling technology (FDT) perimetry to discriminate between healthy eyes and those with early glaucoma, classified based on standard automated perimetry (SAP) and optic disc appearance. To determine the agreement among instruments f...
The plasticity of cell-cell adhesive structures is crucial to all normal and pathological morphogenetic processes. The molecular principles of this plasticity remain unknown. Here we study the roles of two dimerization interfaces, the so-called strand-swap and X dimer interfaces of E-cadherin, in the dynamic remodeling of adherens junctions using photoactivation, calcium switch, and coimmunopre...
We consider the problem of accurately estimating a high-dimensional sparse vector using a small number of linear measurements that are contaminated by noise. It is well known that standard computationally tractable sparse recovery algorithms, such as the Lasso, OMP, and their various extensions, perform poorly when the measurement matrix contains highly correlated columns. We develop a simple g...
In this paper a new credit risk model for credit derivatives is presented. The model is based upon the ‘Libor market’ modelling framework for default-free interest rates. We model effective default-free forward rates and effective forward credit spreads as lognormal diffusion processes, and recovery is modelled as a fraction of the par value of the defaulted claim. The newly introduced survival...
OBJECTIVE Research has raised questions about the ability of clinicians to make reliable diagnostic judgments about personality. The aim of this study was to assess the reliability and validity of the dimensional diagnosis of pathological personality traits with the Shedler-Westen Assessment Procedure-200 (SWAP-200) Q sort. METHOD Two clinician/judges independently described 24 outpatients us...
purpose : to evaluate the efficacy of pattern visual evoked potentials (pvep), standard automated perimetry (sap), short-wavelength automated perimetry (swap), contrast sensitivity (cs), stereoacuity testing in detecting subclinical visual impairment in visually asymptomatic patients with multiple sclerosis (ms) and no history of optic neuritis methods : twenty-seven eyes of 27 patients (7 male...
PURPOSE To determine the magnitude of the homogeneous, LF(Ho), and the heterogeneous, LF(He), components of the long-term fluctuation (LF) in glaucoma suspects and in stable primary open angle glaucoma (POAG) patients undergoing short-wavelength automated perimetry (SWAP) and to compare the magnitude of the SWAP LF components with those elicited by standard white-on-white (W-W) perimetry. MET...
