OBJECTIVE The aim of this study is to explore the resting-state functional connectivity (FC) differences between the paired default mode network (DMN) subregions in patients with primary insomnia (PIs). METHODS Forty-two PIs and forty-two age- and sex-matched good sleepers (GSs) were recruited. All subjects underwent the resting-state functional magnetic resonance imaging scans. The seed-base...
The inositol phospholipids (PIs) comprise a family of eight species with different combinations of phosphate groups arranged around the inositol ring. PIs are among the most versatile signaling molecules known, with key roles in receptor-mediated signal transduction, actin remodeling and membrane trafficking. Recent studies have identified effector proteins and specific lipid-binding domains th...
Each organization exists for the achievement of certain goals. To ensure continued success, the organization should monitor its performance w.r.t. these goals. Performance is often evaluated by estimating performance indicators (PIs). In most existing organization modeling approaches the relation between PIs and goals is implicit. This paper proposes a formal approach for modeling goals based o...
کار اصلی در روش های حجم محدود، تخمین صحیح مقادیر روی سطوح گذرنده شارها براساس مقادیر محاسبه شده در گره ها یا مراکز سلول ها است. در این راستا، رهیافت بالادست از کارآمدترین روش ها در تخمین مقادیر روی سطوح حجم کنترلی است. رهیافت بالادست با تکنیک های متنوع و دقت های مناسبی در روش های حجم محدود روی انواع شبکه های باسازمان و بی سازمان توسعه یافته است. در پژوهش حاضر، روش بالادست مبتنی بر فیزیک جریان (...
The BESSY II injector system consists of a 50MeV Linac, installed in preparation for TopUp operation, and a fastramping Booster synchrotron. The system provides injection efficiencies into the BESSY II Storage Ring well above 90%. This contribution reports on the present status, measurements of energy acceptance as well as studies on coupled bunch-by-bunch instability. Requirements for BESSY VS...
This paper presents the results of a qualitative research that investigates the presence of HCI disciplines in the Public Universities of Paraná State. Among the results, the research presents a comparison of the syllabus proposed by the Brazilian educational institutions with the syllabus offered by the HCI disciplines investigated. Information about the number of students, the period when the...
The power density in high performance systems continues to rise with every process technology generation, thereby increasing the operating temperature and creating ‘hot spots’ on the die. As a result, the performance, reliability and power consumption of the system degrade. To avoid these ‘hot spots’, ‘temperature-aware’ design has become a must. For low-power embedded systems though, it is not...
The stability of a plasma/semiconductor for small fluctuations in the intensity of plane electromagnetic beam has been studied when a non-linearity in the dielectric constant appears on account of the diffusion of non-uniformly heated carriers (due to fluctuations in the intensity of the beam). Fluctuations of optimum size and long duration have been found to grow at moderate powers. The effect...
In this paper, we consider a microgrid system with uncertainties in wind power generation due to environmental conditions and mechanical failures. The system is described by Agent-Based Modelling (ABM). Prediction Intervals (PIs) are estimated to characterize the uncertain environmental parameters of the microgrid working scenarios. The estimation is made by a Genetic Algorithm (GA) – trained N...
The paper proposes a novel multi-area state estimator based on wide area measurements where only boundary buses are considered in the coordination level. The power injection measurements are not used during the coordination level reducing the number of states and therefore size of the problem. Instead, a set of pseudo-measurements are included whenever a power injection measurement is available...
