Identifying coherent sub-graphs in networks is important many applications. In power systems, large systems are divided into areas and zones to aid planning control But not every partitioning equally good for all applications; different applications have goals, or attributes, against which solutions should be evaluated. This paper presents a hybrid method that combines conventional graph algorithm with an evolutionary partition network optimize multi-attribute objective function based on...

A number of impedance-based fault location algorithms have been developed for estimating the distance to faults in a transmission network. Each algorithm has specific input data requirements and makes certain assumptions that may or not hold true particular scenario. Without detailed understanding principle each fault-locating method, choosing most suitable can be challenging task. This paper, therefore, presents theory one-ended (simple reactance, Takagi, modified Eriksson, Novosel et al.)...

The authors rated periventricular and subcortical signal hyperintensities on magnetic resonance imaging (MRI) scans in elderly patients with depression normal subjects similar demographic features to examine whether such changes discriminate from they are associated any clinical variables.Two established hyperintensity rating systems were used compare the MRI brain of 48 diagnosed according DSM-III-R 39 subjects.Elderly depressed manifested significantly more severe ratings gray matter than...

OBJECTIVE: The purpose of this study was to examine the relationship between signal hyperintensities—a probable marker underlying pathology—on T2-weighted magnetic resonance brain scans and neuropsychological test findings in elderly depressed normal subjects. METHOD: Elderly subjects with a DSM-III-R diagnosis major depression (N=41) comparison (N=38) participated imaging (1.0-T) hyperintensities periventricular, deep white matter, subcortical gray matter. Hard copies were rated random...

Background and Purpose —Increased frequency severity of signal hyperintensities have been regularly reported in elderly depressed patients compared with normal subjects, however, greater neuroanatomic localization lesions has limited. Methods —T2-weighted MRI scans (n=35) comparison subjects (n=31) were assessed for lateralized discrete brain regions. Results —Logistic regression revealed that left frontal deep white matter ( P <.005) putaminal <.04) significantly predicted depressive...

Purpose The objective of this investigation was to compare the accuracies bone and Ga-67 scintigraphy magnetic resonance imaging (MRI) for diagnosing spinal osteomyelitis determine optimal radionuclide approach disorder. Methods Twenty-two patients, with 24 sites possible osteomyelitis, who underwent three-phase SPECT, MRI without contrast were included in retrospective review. Bone scans interpreted as studies, delayed planar images alone, plus SPECT alone (to identify uptake patterns)....

Background. The hippocampus, amygdala and related functional circuits have been implicated in the regulation of emotional expression memory processes, which are affected major depression. Several recent investigations reported abnormalities these structures adult elderly depressives. Methods. Elderly DSM-III-R unipolar depressives ( N =40) normal controls =46) participated a magnetic resonance imaging study (1.0T). Brain images were obtained coronal plane. Using established anatomical...

One of the main drawbacks existing oscillation damping controllers that are designed based on offline dynamic models is adaptivity to power system operating condition. With increasing availability wide-area measurements and rapid development identification techniques, it possible identify a measurement-based transfer function model online can be used tune controller. Such could capture all dominant modes for adaptive coordinated control. This paper describes comprehensive approach low-order...

This paper presents a new framework to improve the quality of streaming synchrophasor measurements with existence missing data and bad data. The method exploits low-rank property Hankel structure identify correct data, as well estimate fill in is advantageous compared existing methods literature that only by leveraging observation matrix. proposed algorithm can efficiently differentiate event from even simultaneous consecutive has been verified through numerical experiments on recorded datasets.

Malignant gliomas are extremely resistant to therapies that induce apoptosis, but less autophagy. Therefore, drugs targeting autophagy promising in the management of malignant gliomas. In this study, we investigated anti‐glioma potential curcumin vitro , and further examined molecular mechanisms curcumin‐induced cell death human glioma. Here, provide evidence is cytotoxic against glioma lines, mechanism caused by associated with features Curcumin suppresses growth cells via ROS‐dependent...

A challenge in transmission-distribution coordination is how to quickly and reliably coordinate Distributed Energy Resources (DERs) across large multi-stakeholder Distribution Networks (DNs) support the Transmission Network (TN), while ensuring operational constraints continue be met within DN. Here we propose a hierarchical feedback-based control architecture for of DERs DNs, enabling DN respond power set-point requests from System Operator (TSO) maintaining local constraints. Our scheme...

Background. Several clinical and neuroimaging investigations support the notion that underlying brain changes may relate to depression in older patients, especially those with a later-age initial episode. However uncertainty still exists about diagnostic pathogenic significance of structural abnormalities aged depressives, part because many studies lack all-elderly age-similar normal comparison populations. Methods. Brain morphology elderly depressives ( N = 30) controls 36) was compared by...

A thymidylate synthase (TS)-ribonucleoprotein (RNP) complex composed of TS protein and the mRNA tumor suppressor gene p53 was isolated from cultured human colon cancer cells. RNA gel shift assays confirmed a specific interaction between protein-coding region mRNA, in vitro translation studies demonstrated that this resulted repression translation. To demonstrate potential biological role protein-p53 interaction, Western immunoblot analysis revealed nearly undetectable levels...

Low serum 25-OHD in female Arab subjects, which may predispose their infants to hypocalcaemia, has been suggested be due inadequate sunshine exposure, but include other sociobiological factors. The effects of duration exposure--weighted against the magnitude clothing (UV exposure) and variables such as age, education living accommodation--on mineral status 33 UAE national women childbearing age were compared with those 25 non-Gulf Arabs seventeen Europeans. Serum concentrations calcium,...

Several techniques have been developed to estimate the load parameters in power systems. Most of existing algorithms mainly focus on estimating for offline studies. With on-going smart grid development, high-resolution data at faster rates are available allow estimation real time. This paper addresses challenges online using phasor measurement unit data. A novel adaptive search-based algorithm model is presented here. In this paper, a static used with Z (constant impedance), I current), and...
