Transverse Hilbert Schemes and Completely Integrable Systems

Via the transverse Hilbert scheme construction, we associate a holomorphic completely integrable system to a surface $S$ endowed with a holomorphic symplectic form $\omega$ and a projection onto $\mathbb{C}$. We provide a full characterization of the completely integrable systems that arise in this way.Comment: 12 page

Arabic parsing using grammar transforms

We investigate Arabic Context Free Grammar parsing with dependency annotation comparing lexicalised and unlexicalised parsers. We study how morphosyntactic as well as function tag information percolation in the form of grammar transforms (Johnson, 1998, Kulick et al., 2006) affects the performance of a parser and helps dependency assignment. We focus on the three most frequent functional tags in the Arabic Penn Treebank: subjects, direct objects and predicates . We merge these functional tags with their phrasal categories and (where appropriate) percolate case information to the non-terminal (POS) category to train the parsers. We then automatically enrich the output of these parsers with full dependency information in order to annotate trees with Lexical Functional Grammar (LFG) f-structure equations with produce f-structures, i.e. attribute-value matrices approximating to basic predicate-argument-adjunct structure representations. We present a series of experiments evaluating how well lexicalized, history-based, generative (Bikel) as well as latent variable PCFG (Berkeley) parsers cope with the enriched Arabic data. We measure quality and coverage of both the output trees and the generated LFG f-structures. We show that joint functional and morphological information percolation improves both the recovery of trees as well as dependency results in the form of LFG f-structures

Automatic treebank-based acquisition of Arabic LFG dependency structures

A number of papers have reported on methods for the automatic acquisition of large-scale, probabilistic LFG-based grammatical resources from treebanks for English (Cahill and al., 2002), (Cahill and al., 2004), German (Cahill and al., 2003), Chinese (Burke, 2004), (Guo and al., 2007), Spanish (O’Donovan, 2004), (Chrupala and van Genabith, 2006) and French (Schluter and van Genabith, 2008). Here, we extend the LFG grammar acquisition approach to Arabic and the Penn Arabic Treebank (ATB) (Maamouri and Bies, 2004), adapting and extending the methodology of (Cahill and al., 2004) originally developed for English. Arabic is challenging because of its morphological richness and syntactic complexity. Currently 98% of ATB trees (without FRAG and X) produce a covering and connected f-structure. We conduct a qualitative evaluation of our annotation against a gold standard and achieve an f-score of 95%

DESAIN INTERIOR WINE AND DINE HOUSE DI YOGYAKARTA (Dengan Pendekatan Desain Klasik-Eklektik)

ABSTRAK Wine merupakan minuman yang sangat digandrungi oleh golongan menengah ke atas. Hal ini dapat dirasakan adanya eksekutif-eksekutif muda yang berkumpul untuk berbagi pengalaman mengenai wine. Maka dari itu diperlukan suatu tempat untuk menampung komunitas ini sekaligus mendapatkan edukasi. Di Yogyakarta sudah terdapat beberapa tempat yang menjual wine, tetapi belum ada wadah yang menampung penikmat wine. Perancangan Wine and Dine House ini sendiri memiliki tujuan agar dapat memberikan pengetahuan tentang memilih, menyimpan dan cara minum wine yang benar. Fasilitas yang direncanakan meliputi lobi, area informasi, galeri dan penjualan, restoran, bar, area penyimpanan, kantor, dan servis. Selain mendapatkan edukasi pengunjung juga mendapatkan hiburan berupa restoran untuk menikmati hidangan bertaraf internasional dengan diiringi aluman musik jazz dari piano dan sexofon dan juga digunakan untuk komunitas wine. Dapat pula sebagai tempat berkumpul dengan dilengkapi VIP area. Sesuai dengan karakter dan tempat penyimpanan wine itu sendiri, maka tema yang diusung pada perencanaan ini adalah ruang tersembunyi dengan pembawaan suasana interior seolah-olah berada langsung di gudang penyimpanan wine, sehingga pengunjung dapat merasakan interaksinya dengan wine. Unsur desain klasik-eklektik akan dipakai dalam perancangan karena dirasa paling pas sebagai tema perancangan interior ini. ABSTRACT Wine is a popular beverage among middle-up society. It can be shown by the young executives that gather together to share experiences about wine. Having it said, it is important to have a place to contain this community as well as gaining education. There are already some places in Yogyakarta that sell wine, but not accommodates for the wine connoisseur. Wine and dine house design itself has the purpose in order to provide knowledge about choosing, saving and the manner of drinking wine. The facilities planned include lobby, information area, gallery and store, restaurant, bar, storage area, office, and service. Other than gaining education, visitors also get entertainment in form of restaurant to enjoy international standard cuisine with a jazz music from a piano and saxophone as its background and it is also used for the wine community. It can also be use as a gathering place with equipped VIP area. In accordance with the character of wine itself, then the design theme refers to a hidden room with the interior atmosphere as if being directly in wine storage, so the visitors can feel their interaction with wine. Element of the design classiceclectic will be used in design because it has the most fitting theme of this interior design

Parsing Arabic using treebank-based LFG resources

In this paper we present initial results on parsing Arabic using treebank-based parsers and automatic LFG f-structure annotation methodologies. The Arabic Annotation Algorithm (A3) (Tounsi et al., 2009) exploits the rich functional annotations in the Penn Arabic Treebank (ATB) (Bies and Maamouri, 2003; Maamouri and Bies, 2004) to assign LFG f-structure equations to trees. For parsing, we modify Bikel’s (2004) parser to learn ATB functional tags and merge phrasal categories with functional tags in the training data. Functional tags in parser output trees are then "unmasked" and available to A3 to assign f-structure equations. We evaluate the resulting f-structures against the DCU250 Arabic gold standard dependency bank (Al-Raheb et al., 2006). Currently we achieve a dependency f-score of 77%

Hypoxia enhances the tissue protective effect of erythropoietin and its analogues in an endothelial cell injury model

PO has tissue protective activities in ischemic disease but also has prothrombotic, erythropoietic effects. Carbamylated EPO (CEPO) retains the protective actions without the erythropoietic effects. To assess the potential of these molecules in atherosclerosis (an ischemic heart disease), we investigated EPO and CEPO in an in vitro model of injury using bovine aortic endothelial cells (BAEC) in hypoxia and normoxia.. BAECs were grown to confluence in 10% FBS in 12 well culture plates. They were then cultured under normoxia (21% oxygen) or hypoxia (5% oxygen) 24 h prior to their use in an injury model using the ‘scratch assay.’ The effects of EPO and CEPO on endothelial closure were assessed using a range of concentrations (0-10 ng/mL). In separate experiments, the effects of EPO and CEPO on BAEC proliferation and chemotaxis were also assessed under similar hypoxic conditions. Gene expression of the receptors that may be involved in their protective pathway [EPOR and the β common chain receptor (βCR)] were assessed using quantitative PCR. The effects of both EPO and CEPO were enhanced under hypoxic conditions (13 ± 2.6 %, and 10 ± 1.69 %, p0.05). Whilst, the expression of EPOR gene increased by 2.1 ± 0.8 folds (p<0.05) In hypoxia, βCR expression was not affected by the change in oxygen tension. The effects of EPO and CEPO in the scratch assay appeared to be mediated by enhancing cell proliferation and migration of BAECs (p<0.05). In conclusion, the enhanced effects of EPO and CEPO on endothelial cells under hypoxia requires further investigation in processes in which hypoxia may play a role, e.gfor example. in atherogenesis and re-stensosis following angioplasty
