The area under the ROC curve (AUC) has beenadvocated as an evaluation criterion for the bi-partite ranking problem. We study uniform con-vergence properties of the AUC; in particular, wederive a distribution-free uniform convergencebound for the AUC which serves to bound theexpected accuracy of a learned ranking functionin terms of its empirical AUC on the traini...

Background: Conflicting results from previous studies on the effect of bronchial challenge on ven¬ tilatory patterns in asthmatics may be due to airflow obstruction present before induction of bron¬ chospasm onset, as well as the different degrees of bronchoconstriction induced. Purpose and methods: We examined the ventilatory response to stepwise increments in respiratory resistance (Rrs) indu...

The topic of charge-transfer (CT) complexation of vital drugs has attracted considerable attention in recent years owing to their significant physical and chemical properties. In this study, CT complexes derived from the reaction of the anti-hyperuricemic drug allopurinol (Allop) with organic p-acceptors [(picric acid (PA), dichlorodicyanobenzoquinone (DDQ) and chloranil (CHL)] were prepared, i...

Mechanical aspects of the cellular environment can influence cell function, and in this context hydrogels can serve as an instructive matrix. Here we report that physicochemical properties of hydrogels derived from polysaccharides (agarose, κ-carrageenan) having an α-helical backbone can be tailored by inducing a switch in the secondary structure from α-helix to β-sheet through carboxylation. T...

Formulation of the problem. An actual problem when creating web resources is test-ing designed design, which direction testing user interface. This paper con-siders ways to automate analysis interface pages in terms visual perception man. The aim work. work improve quality automated graphical based on use methods color digital images and detection graphic objects. Methods selecting objects imag...

We study average consensus when, simultaneously, the topology is random (links are offline or onlineat random times) and the communication among sensors is corrupted by additive noise. Additive noisecauses the states of the standard average consensus algorithm to diverge. To overcome this, we considertwo modifications to average consensus: 1) the A−ND algorithm with weights decaying...

Centropages typims is a temperate neritic-coastal species of the North Atlantic Oceans, generally found between thelatitudes of the Mediterranean and the Norwegian Sea. Therefore, the species experiences a large number of environmentsand adjusts its life cycle in response to changes in key abiotic pa rameters such as temperature. Using data from the Con-tinuous Plankton Recorder (CP...

We develop distributed stochastic convex op-timization algorithms under a delayed gradi-ent model in which server nodes update pa-rameters and worker nodes compute stochas-tic (sub)gradients. Our setup is motivated bythe behavior of real-world distributed com-putation systems; in particular, we analyzea setting wherein worker nodes can be dif-ferently slow at dif...

#{149} Be familiar with the radiologic manifestations that allow differentiation of the majority of enchondromas and intramedullary chondrosarcomas affecting the appendicular skeleton. Distinction of enchondroma versus intramedullary chondrosarcoma a!fecting the appendicular skeleton (proximal to the metacarpals and metatarsals) is a frequent diagnostic dilemma. The authors studied a large seri...

The aim of this study was to evaluate the influence different packaging materials [standard foil: BOPP (biaxially oriented polypropylene)/PET (polyester)/PE (polyethylene) for upper layer, and APET (polyethylene terephthalate)/PE bottom layer; foil 1: PP (polypropylene)/PET/PE/EVOH (ethylene-vinyl alcohol copolymer)/PE PP/PE/EVOH/PE 2: PP/PET/PE/EVOH/PE PA (polyamide)/EVOH/PE 3: PP/PET/PE PA/EV...
