We have performed the first non-parametric joint X-ray/SZE modeling of ICM properties (A2163, A2204) out to r200. Stacking analysis in progress, also combination with Suzaku data. Multi-pixel bolometer imaging data is now able to verify ICM entropy the features at the cluster core, and also the dropping gas temperature at large radii, independent of X-ray spectroscopy. With better control of SZE statistical and X-ray background uncertainties, we can go beyond r200 with available instruments.

In this paper, we present a system for the phonemic transcription of Hungarian. Beside the implementation of rules describing default letter-to-phoneme correspondences and morphophonological al- ternations, the tool incorporates the knowledge of a Hungarian morphological analyzer in order to be able to detect compound and other morpheme boundaries, and it contains a rich lexicon of entries with irregular pronunciation. It is shown that the system performs well even on texts containing a high number of foreign names. 1 INTRODUCTION In the research reported about in this study, our goal was to imple- ment a system that can automatically transform written Hungarian to its phonemic representation.

Abstract: Clinical treatments for ischemic stroke are limited. Neural stem cell (NSC) transplantation can be a promising therapy. Clinically, ischemia and subsequent reperfusion lead to extensive neurovascular injury that involves inflammation, disruption of the blood-brain barrier, and brain cell death. NSCs exhibit multiple potentially therapeutic actions against neurovascular injury. Currently, tissue plasminogen activator (tPA) is the only FDA-approved clot-dissolving agent. While tPA’s thrombolytic role within the vasculature is beneficial, tPA’s non-thrombolytic deleterious effects aggravates neurovascular injury, restricting the treatment time window (time-sensitive) and tPA eligibility. Thus, new strategies are needed to mitigate tPA’s detrimental effects and quickly mediate vascular repair after stroke. Up to date, clinical trials focus on the impact of stem cell therapy on neuro-restoration by delivering cells during the chronic stroke stage. Also, NSCs secrete factors that stimulate endogenous repair mechanisms for early-stage ischemic stroke. This review will present an integrated view of the preclinical perspectives of NSC transplantation as a promising treatment for neurovascular injury, with an emphasis on early-stage ischemic stroke.

Esqub, F. Aguil6 and M.A. Fiol Dept. de Maremdlica i Telerndtica, Universitor PolitPcnica de Caialunya, Barcelona, Spain Received 20 January 1989 Revised 6 January 1990 Esque, P., F. Aguilo and M.A. Fiol, Double commutative-step digraphs with minimum diameters, Discrete Mathematics 114 (1993) 1477157. From a natural generalization to E* of the concept of congruence, it is possible to define a family of 2-regular digraphs that we call double commutative-step digraphs. They turn out to be Cayley diagrams of Abelian groups generated by two elements, and can be represented by L-shaped tiles which tessellate the plane periodically. A double commutative-step digraph with n vertices is said to be tight if its diameter attains the lower bound Ib(n)=r&l -2. In this paper, the tiles associated with tight double commutative-step digraphs are fully characterized. This allows us to construct such digraphs and also to find for which values of II they exist. In particular, we characterize a complete set of families of tight double fixed-step digraphs (also called circulant digraphs), generalizing some previously known results. 1. Introduction Let M be an integral 2 x 2 matrix with det M =n>O. Let 2’ denote the additive group of (column) 2-vectors with integral coordinates. The set MZ2, whose elements are linear combinations (with integral coefficients) of the column vectors of M, is said to be the lattice generated by M.

  • On the Creation of a Pronunciation Dictionary for Hungarian
    On the creation of a pronunciation dictionary for Hungarian Stephen M. Grimes [email protected] August 2007 Abstract This report describes the process of creating a pronunciation dictionary and phonological lexicon for Hungarian for the purpose of aiding in linguistic research on Hungarian phonology and phonotactics. The pronunciation dictionary was created by transforming orthographic forms to pronunciation representations by taking advantage of systematic deviations between Hungarian orthography and pronunciation. It is argued that the “automated” creation of such a dictionary is reasonably expected to be accurate due to the relative similarity of Hungarian orthography to actual pronunciation. This document includes discussion of goals and standards for creating a Hungarian pronunciation dictionary, and each phonological change creating a mismatch between orthography and pronunciation is highlighted. Future developments and additions to the current dictionary are also suggested as well as strategies for evaluating the quality of the dictionary. Finally, potential applications to linguistic research are discussed. 1 Introduction While students of the English language quickly learn that English spelling is by no means consistent, many Hungarians believe that the Hungarian alphabet is completely phonetic. Here, a phonetic alphabet refers to the existence of a one-to-one mapping between symbol and sound. It can quite easily be demonstrated by counter-example that 1 Hungarian orthography is not phonetic, and in fact several types of orthographic- pronunciation discrepancies exist. Consider as an example the word /szabadság/ 1 [sabatʃ:a:g] ‘freedom, liberty’ , in which no fewer than four orthographic-pronunciation discrepancies can be identified with the written form of this word: (1) a.

This allows for smaller Anchor SZ without additional blowing out of the drill-hole. spacings and edge distances with high loads. Through deeper set- ting, the variable anchorage depth of Highload Anchor SZ allows higher permissable shear loads in many cases, extending its range of possible uses. Three dierent models of the Highload Anchor SZ are available: Screw/washer SZ-S, Bolthead SZ-B and for ush surface mounting SZ-SK. All models have been shock-tested by the federal oce for population protection in Bern/Switzerland, the models from M8 are also approved for use under seismic actions C1 and C2. Advantages - High tension and shear loads - Variable anchoring depths for even higher shear loads - Screw/washer (SZ-B) model and at head (SZ-SK) model for nished surfaces - Can be dismantled with a ush surface result (only the cone and expansion sleeve remain in the drill-hole) - Smaller spacings and edge distances - ICC Evalution Service listing, USA - Fire protection approved - Approved to use under seismic action according to the performance category C1+C2 (M8-M24) Applications Medium to highload anchoring in cracked and non-cracked concrete, e.g.
