Empty elements (EEs) play a critical role in Chinese syntactic, semantic and discourse analysis. Previous studies employ a language-independent sentence-level approach to EE recovery, by casting it as a linear tagging or structured parsing problem. In comparison, this paper proposes a clauselevel hybrid approach to address specific problems in Chinese EE recovery, which recovers EEs in Chinese ...

Extraskeletal Ewing’ sarcoma (EES) is a rare soft tissue tumor morphologically indistinguishable from the osseous Ewing’s sarcoma (ES). We report a case of recurrent EES of the breast that, to the best of our knowledge, has rarely been reported. It was initially confused for a cyst on ultrasound. In addition, MRI and breast-specific gamma imaging (BSGI) in our case have complementary value over...

Introduction: Extraosseous Ewing’s sarcoma (EES) of the head and neck region is a rare occurrence, and Ewing’s sarcoma of the parapharyngeal space is even rarer. To the best of our knowledge, only three cases of EES of the parapharyngeal space have been reported in the literature.   Case Report: We report a rare case of EES of the parapharyngeal space in an 8-year-old girl. She presented with c...

Cette communication pr esente une nouvelle classe d'algorithmes d' egalisation aveugle pour la transmission des donn ees MAP ou MAQ a travers un canal de communication a phase non-minimale. Cette classe d'algorithmes est deriv ee en minimisant un crit ere d eterministe qui impose un ensemble de contraintes bas ees sur la propriet e du module constant de la constellation emise et permet l'accel ...

r esum e Quatre m ethodes de r esolution de syst emes d' equations polynomiales sont pr esent ees et implant ees dans un cadre commun. Ces m ethodes sont celles de Wu ((Wu87]), Lazard ((Laz91]), Kalkbrener ((Kal91]) et Wang ((Wan93b]). Elles sont compar ees sur divers exemples avec une attention par-ticuli ere port ee a l'eecacit e, la concision et la lisibilit e des sorties. Abstract Four meth...

Everolimus-eluting stents (EES) represent the next generation of drug-eluting stents (DES). Important design modifications include thin strut stent backbones, less inflammatory and more biocompatible polymers, and lower drug dosing. The cobalt chromium EES fluoropolymer XIENCE V stent has been the most extensively studied of such stents. In animal models, this stent demonstrated minimal vessel ...

Environmental concerns about using fossil fuels, and their resource constraints along with energy security concerns, have spurred great interest in generating electrical energy from renewable sources. The variable and stochastic nature of renewable sources, however, makes solar and wind power diffi cult to manage, especially at high levels of penetration. Electrical energy storage (EES) is nece...

▪ This article starts with a brief review of the European Employment Strategy (EES) and a general evaluation of its scope and limitations, then provides an assessment of the five-year review conducted by the European Commission. It examines the new form that has been given to the EES for the 2003 exercise, on the basis of the conclusions drawn from the five-year review. It argues that this chan...

Polling sur un graphe avec des temps d'inter-arriv ees et de services avec distributions g en erales Abstract Nous consid erons un syst eme de polling sur un graphe avec des temps d'inter-arriv ees, de services et de d eplacements du serveur qui forment des suites i.i.d. Nous pr esentons des conditions suusantes et n ecessaires de stabilit e, en utilisant une analyse de la d erive de la charge ...

Two new classes of nodal methods, respectively weakly and strongly discontinuous ones, are introduced and applied to the neutron transport equations in X-Y geometry in the discrete ordinates approximation. These methods are then applied to approximate the solution of a well-known benchmark problem of the nuclear engineering literature. The results obtained are nally compared to the ones obtaine...
