Current Approaches to Punctuation in Computational Linguistics

Some recent studies in computational linguistics have aimed to take advantage of various cues presented by punctuation marks. This short survey is intended to summarise these research efforts and additionally, to outline a current perspective for the usage and functions of punctuation marks. We conclude by presenting an information-based framework for punctuation, influenced by treatments of several related phenomena in computational linguistics. © 1997 Kluwer Academic Publishers

Preparation of Ion Imprinted SPR Sensor for Real-Time Detection of Silver(I) Ion from Aqueous Solution

The aim of the submitted study is to develop molecular imprinting based surface plasmon resonance (SPR) sensor for real-time silver ion detection. For this purpose polymeric nanofilm layer on the gold SPR chip surface was prepared via UV polymerization of acrylic acid at 395 nm for 30 minutes. N-methacryloyl- L cysteine used as the functional monomer to recognize the silver(I) ions from the aqueous solutions and methylene bisacrylamide used as the crosslinker for obtaining structural rigidity of the formed cavities. Silver(I) solutions with different concentrations were applied to SPR system to investigate the efficiency of the imprinted SPR sensor in real time. For the control experiments, non-imprinted SPR sensor was also prepared as described above without addition of template “silver(I) ions”. Prepared SPR sensors were characterized with atomic force microscopy (AFM). In order to show the selectivity of the silver(I) imprinted SPR sensor, competitive adsorption of Cu(II), Pb(II), Ni(II) ions was investigated.

An English Architect in the 19th Century Istanbul: William James Smith and Taşkışla

An English architect William James Smith had worked in Istanbul from 1842 to 1856, a most politically influential period for the British Empire. Smith, after his appointment to the prestigious project for the new Istanbul Embassy Building of United Kingdom, whose conceptual design was probably by renowned architect Sir Charles Barry, had attained the interest and trust of Ottoman statesmen. Consequently he was assigned to realise a number of important architectural projects contributing to the modernization of Ottoman Architecture. Some of the Smith’s important works for the Ottoman Porte are: A military hospital [Gümüşsuyu Askeri Hastanesi], a naval hospital, a school of medicine later known as Mecidiye Kışlası then Taşkışla, a part of the Selimiye Barracks, a Glass Pavilion in Dolmabahçe Palace and Tophane Imperial Kiosk [Tophane Kasrı] for Sultan Abdülmecid; a building for the Board of Trade, renovation of the Naum Theatre. His commissions for so many important buildings, in spite of the presence of the notable architects, namely Balyan and Fossati, is a proof of Sultan’s appreciation of Smith’s works. Smith worked for both the British Empire and the Ottoman Sultan for a considerable number of grand scale projects. Being Smith’s first work of grand scale, Taşkışla has had a major role in the history of the Ottoman Empire and Istanbul in addition to its own interesting construction history

Unary probabilistic and quantum automata on promise problems

We continue the systematic investigation of probabilistic and quantum finite automata (PFAs and QFAs) on promise problems by focusing on unary languages. We show that bounded-error QFAs are more powerful than PFAs. But, in contrary to the binary problems, the computational powers of Las-Vegas QFAs and bounded-error PFAs are equivalent to deterministic finite automata (DFAs). Lastly, we present a new family of unary promise problems with two parameters such that when fixing one parameter QFAs can be exponentially more succinct than PFAs and when fixing the other parameter PFAs can be exponentially more succinct than DFAs.Comment: Minor correction

Stability of white matter changes related to Huntington's disease in the presence of imaging noise: a DTI study.

Movement artifacts and other sources of noise are a matter of concern particularly in the neuroimaging research of movement disorders such as Huntington's disease (HD). Using diffusion weighted imaging (DWI) and fractional anisotropy (FA) as a compound marker of white matter integrity, we investigated the effect of movement on HD specific changes in magnetic resonance imaging (MRI) data and how post hoc compensation for it affects the MRI results. To this end, we studied by 3T MRI: 18 early affected, 22 premanifest gene-positive subjects, 23 healthy controls (50 slices of 2.3 mm thickness per volume, 64 diffusion-weighted directions (b = 1000 s/mm2), 8 minimal diffusion-weighting (b = 100 s/mm2)); and by 1.5 T imaging: 29 premanifest HD, 30 controls (40 axial slices of 2.3 mm thickness per volume, 61 diffusion-weighted directions (b = 1000 s/mm2), minimal diffusion-weighting (b = 100 s/mm2)). An outlier based method was developed to identify movement and other sources of noise by comparing the index DWI direction against a weighted average computed from all other directions of the same subject. No significant differences were observed when separately comparing each group of patients with and without removal of DWI volumes that contained artifacts. In line with previous DWI-based studies, decreased FA in the corpus callosum and increased FA around the basal ganglia were observed when premanifest mutation carriers and early affected patients were compared with healthy controls. These findings demonstrate the robustness of the FA value in the presence of movement and thus encourage multi-center imaging studies in HD

Моделирование оценки потребности региона в контейнерных перевозках

ABSTRACT The article is devoted to development of a model for substantiating a region’s need for containerization of cargo transportation. The model includes two interrelated elements: a method for substantiating container suitability for cargoes and an imitation algorithm for planning of the region’s need for containerization. The planning of the need for containerization links the demand of enterprises for transportation (taking into account the levels of product container suitability) and the available resources of the container transport system (terminals, container fleet, rolling stock). Further development of the model assumes assessment of costs and benefits of the region from development of the container system. Verification of the simulation model at the example of Sverdlovsk region demonstrates its efficiency and adequacy of reality. Keywords: container transportation, containerization, container suitability of cargo, social and economic system of the region, development of the region, resources, simulation model, organization of interaction.Полный текст на англ. языке находится в прилагаемом файле ПДФ (англ. версия следует после русской версии).Статья посвящена разработке модели обоснования потребности региона в контейнеризации грузовых перевозок. Модель включает два взаимосвязанных элемента: методику обоснования контейнеропригодности грузов региона и имитационный алгоритм планирования потребности региона в контейнеризации. Планирование потребности в контейнеризации увязывает спрос предприятий на перевозки (с учётом уровней контейнеропригодности продукции) и имеющиеся ресурсы контейнерной транспортной системы (терминалы, контейнерный парк, подвижной состав). Дальнейшее развитие модели предполагает оценку затрат и выгод региона от развития контейнерной системы. Верификация имитационной модели на примере Свердловской области демонстрирует её работоспособность и адекватность действительности

Entamoeba histolytica Dmc1 Catalyzes Homologous DNA Pairing and Strand Exchange That Is Stimulated by Calcium and Hop2-Mnd1

Meiosis depends on homologous recombination (HR) in most sexually reproducing organisms. Efficient meiotic HR requires the activity of the meiosis-specific recombinase, Dmc1. Previous work shows Dmc1 is expressed in Entamoeba histolytica, a eukaryotic parasite responsible for amoebiasis throughout the world, suggesting this organism undergoes meiosis. Here, we demonstrate Dmc1 protein is expressed in E. histolytica. We show that purified ehDmc1 forms presynaptic filaments and catalyzes ATP-dependent homologous DNA pairing and DNA strand exchange over at least several thousand base pairs. The DNA pairing and strand exchange activities are enhanced by the presence of calcium and the meiosis-specific recombination accessory factor, Hop2-Mnd1. In combination, calcium and Hop2-Mnd1 dramatically increase the rate of DNA strand exchange activity of ehDmc1. The biochemical system described herein provides a basis on which to better understand the role of ehDmc1 and other HR proteins in E. histolytica
