Two widely used problems are the Satisfiability problem (SAT) and the Curriculum-Based Course Timetabling (CB-CTT) problem. The SAT problem searches for an assignment that make true a certain boolean formula. On the other side, the CB-CTT involves the task of scheduling lectures of courses to rooms, considering teacher availability, a specified curricula, and a set of constraints. Given the adv...

Outgoing longwave radiation (OLR) data are one of the key factors in studying balance earth–atmosphere system East Asia. It is great significance to explore influence on OLR. This paper processes nearly 19 years, from September 2002 February 2022, and conducts in-depth research using exponential smoothing method, empirical orthogonal decomposition (EOF), correlation analysis, other methods. We ...

abstract  background: at present, differentiation between exudative and transudative pleural  effusion is based solely on laboratory measures and is time-consuming. asimple  bedside method would be of great help to differentiate between these two types of effusions.  we present a new method for this purpose assessed in 46 patients.  methods: standard laboratory tests and our method were tested ...

BACKGROUND Although health-related quality of life (HRQOL) instruments may offer satisfactory results, their length often limits the extent to which they are actually applied in clinical practice. Efforts to develop short questionnaires have largely focused on reducing existing instruments. The approaches most frequently employed for this purpose rely on statistical procedures that are consider...

The flow of genetic information from the chromosome to protein in all living organisms consists two steps: (1) copying coded DNA into an mRNA intermediate via transcription by RNA polymerase, followed (2) translation this a polypeptide ribosome. Unlike eukaryotes, where and are separated nuclear envelope, bacterial cells, these processes occur within same compartment. This means that pioneering...

The single-crystal X-ray structures of the copper 1,5,9-cyclododecatriene complexes (cis,cis,transC12H18)Cu(OTf), cct-1, (cis,trans,trans-C12H18)Cu(OTf), ctt-1, and (trans,trans,trans-C12H18)Cu(OTf), ttt1, have been determined. In all three compounds, the triflate ligand and all three CdC double bonds of the triene are bound to the copper center, which adopts a distorted tetrahedral coordinatio...

The automated assembly of alternate test forms for online delivery provides an alternative to computer-administered, fixed test forms, or computerized-adaptive tests when a testing program migrates from paper/pencil testing to computer-based testing. The weighted deviations model (WDM) heuristic is particularly promising for automated test assembly (ATA) because it is computationally straightfo...

The distribution of glutamate-like immunoreactivity (Glu-LI) in the thalamic ventral posterolateral nucleus (VPL) of cats was studied with the EM immunogold technique in order to identify nerve terminal populations that may use glutamate as a neurotransmitter. The investigation was focused on cervicothalamic tract (CTT) terminals, which were labeled by WGA-HRP transported anterogradely from inj...

Previous observations showed that complexes of glucose-regulated protein94 (Grp94) with human IgG, both those isolated from plasma of diabetic subjects and complexes formed in vitro, displayed cytokine-like effects on human umbilical vein endothelial cells (HUVECs), including angiogenic-like transformation capacity that predicted an increased risk of vascular damage. The aim of the present work...

The association of transcription factor 7-like 2 (TCF7L2) gene variants with the pathogenesis of T2D, gestational diabetes and polycystic ovary syndrome (PCOS) was examined. The study involved 1460 individuals: 347 T2D patients (D); 261 gestational diabetics (G); 147 offspring of T2D (O); 329 women with PCOS, and 376 controls (C). The SNPs: rs7901695; rs7903146; rs12255372 in the TCF7L2 gene we...
