Recent years have witnessed a growing interest, theoretically as well as experimentally, in space-variant polarization manipulation for obtaining vectorial beams. In general, vectorial beams are defined as beams having space-variant (transversely nonuniform) polarization state. In this lecture we present new methods for designing, realizing and analyzing nonuniformly polarized and partial polar...

one grotesque catfish specimen was collected in zhangjiang river (upper reach of a secondary tributary of hongshuihe river) in libo county, guizhou province, china. this specimen bears surprising character of four dorsal fins, which have not appeared in any other silurid fishes. but other morphological characters, such as two pairs of barbels, lower jaw projecting beyond upper jaw, the first do...

purpose: to present a case of bilateral idiopathic central serous chorioretinopthy (icsc) complicated by bullous serous retinal detachment (rd). case report: a 26-year old female suffered from acute loss of vision in the both eyes. best spectacle-corrected visual acuity was 1/10 ou. the examination of anterior segment was unremarkable and a mild vitreous reaction was noted. dilated fundus exami...

In this paper, the error-reject trade-off of linearly combined multiple classifiers is analysed in the framework of the minimum risk theory. Theoretical analysis described in [12,13] is extended for handling reject option and the optimality of the error-reject trade-off is analysed under the assumption of independence among the errors of the individual classifiers. Improvements of the error-rej...

We present prototype-based classification schemes, e. g. learning vector quantization, with cost-function-based and geometrically motivated reject options. We evaluate the reject schemes in experiments on artificial and benchmark data sets. We demonstrate that reject options improve the accuracy of the models in most cases, and that the performance of the proposed schemes is comparable to the o...

The design and performance of a band pass filter for UWB communications is presented in this paper. Open loop resonators consisting of parallel arms (stubs) protruding from a 50Ω transmission line create the required rejection bands. The arms height, width and spacing control the bandwidth achieved by the filter. Each pair of arm creates one reject band in the transmission response. Three filte...

Experimental and clinical studies have shown that intracoronary transplantation of autologous bone marrow mesenchymal stem cells (BMSCs) has resulted in regenerated infarcted myocardium and improved left ventricular (LV) function. <span style="font-variant: normal; font-style: normal; f...

Low grade nasopharyngeal papillary adenocarcinoma (LGNPPA) is an extremely rare variant of nasopharyngeal cancer, which exhibits distinct clinicopathological characteristics. Surgical resection has been regarded as the principal treatment. For this, transpalatal or transfacial approach has been classically used for exposure of the field. Up for now, there has been no report on applying endoscop...
