Semantic Matching Using Ontology in Multilingual Environment

The tremendous increase in usage of data over the past few years and the ease of availability of things across the globe any time lead to the Advancement of multilingual database. Storage, retrieval and archiving of data for multi lingual system has been a challenge. Our research project “Semantic Matching using Ontology in Multilingual Environment” is an extension is to look into addressing multi-lingual data. The report focuses on providing design and implementation of multilingual system. These comprise of two main components being (i) Cross Lingual Information Retrieval, and (ii) Indian Language to Indian Language Machine Translation. Consider the context of large scale natural language processing applications in the areas of Cross Lingual IR and Machine Translation, wherein such a model for multilingual dictionary is established. When contrasted to traditional single lingual or bilingual dictionary, the model uses the core concept of Synonym Groupings (synsets) that is used as a way to connect different languages in a crisp and efficient manner

Self-dual gravitational instantons and geometric flows of all Bianchi types

We investigate four-dimensional, self-dual gravitational instantons endowed with a product structure RxM_3, where M_3 is homogeneous of Bianchi type. We analyze the general conditions under which Euclidean-time evolution in the gravitational instanton can be identified with a geometric flow of a metric on M_3. This includes both unimodular and non-unimodular groups, and the corresponding geometric flow is a general Ricci plus Yang-Mills flow accompanied by a diffeomorphism.Comment: Latex, 12 pages; Final versio

Elemental Analysis of Nanomaterial Using Photon-Atom Interaction Based EDXRF Technique

Presence of trace amount of foreign impurities (both metallic and non-metallic) in standard salts used for sample preparation and during the synthesis process can alter the physical and chemical behavior of the pure and doped nano-materials. Therefore, it becomes important to determine concentration of various elements present in synthesized nano-material sample. In present work, the elemental and compositional analysis of nano-materials synthesized using various methods has been performed using photon-atom interaction based energy dispersive x-ray fluorescence (EDXRF) technique. This technique due to its multielement analytical capability, lower detection limit, capability to analyze metals and non-metals alike and almost no sample preparation requirements can be utilized for analysis of nano-materials. The EDXRF spectrometer involves a 2.4 kW Mo anode x-ray tube (Pananalytic, Netherland) equipped with selective absorbers as an excitation source and an LEGe detector (FWHM = 150 eV at 5.895 keV, Canberra, US) coupled with PC based multichannel analyzer used to collect the fluorescent x-ray spectra. The analytical results showed good agreements with the expected values calculated on the basis of the precursor used in preparation of nano-materials

Photoluminescence and Photo-catalytic Activity of Synthesized Nanocrystals

Intrinsic and extrinsic semiconductor nanostructures have attracted great attention due to their size tunable photo-physical and photo-chemical properties. In the present paper, polyvinyl pyrrolidone (PVP) capped Zn1-xEuxS (0.00001≤x≤0.1)nanocrystals have been synthesized by means of a facile chemical synthesis method. Crystallography and morphology of synthesized materials have been deliberated using X-ray diffraction (XRD) and transmission electron microscope (TEM), respectively. Diffraction and electron micrograph studies reveal that the synthesized materials are zinc blende nanocrystals having average particle size ~3nm. Elemental and compositional analyses of the nanocrystals have been done using energy dispersive X-ray fluorescence (EDXRF) technique. Steady state photoluminescence spectra have been recorded for optical characterization of synthesized nanomaterials. Photo-catalytic activity potential of synthesized nanomaterials under UV radiation exposure has been investigated using methylene blue (MB) dye as a test contaminant in aqueous media. Photo-physical and photo-chemical behaviour dependence on doping concentration has been described in detail. Moreover, the sophistication of competition between charge carrier recombination and charge carrier trapping followed by the competition between recombination of trapped carriers and interfacial charge transfer processes have been presented in a fantastic and elaborative way by comparative study of photoluminescence and photo-catalytic activity results

Psychotropic prescribing after hospital discharge in survivors of critical illness, a retrospective cohort study (2012–2019)

Background:Many people survive critical illness with the burden of new or worsened mental health issues and sleep disturbances. We examined the frequency of psychotropic prescribing after critical illness, comparing critical care to non-critical care hospitalised survivors, and whether this varied in important subgroups.Methods:This retrospective cohort study included 23,340 critical care and 367,185 non-critical care hospitalised adults from 2012 through 2019 in Lothian, Scotland, who survived to discharge.Results:One-third of critical care survivors (32 7527/23,340) received a psychotropic prescription within 90 days after hospital discharge (25 14hypnotics; 4mania medicines). In contrast, 1554,589/367,185) of non-critical care survivors received a psychotropic prescription (12 5hypnotics; 2mania medicines). Among patients without psychotropic prescriptions within 180 days prior to hospitalisation, after hospital discharge, the critical care group had a higher incidence of psychotropic prescription (10.3 1610/15,609) compared with the non-critical care group (3.2 9743/307,429); unadjusted hazard ratio (HR) 3.39, 95 3.22–3.57. After adjustment for potential confounders, the risk remained elevated (adjusted HR 2.03, 95 1.91–2.16), persisted later in follow-up (90–365 days; adjusted HR 1.38, 95 1.30–1.46), and was more pronounced in those without recorded comorbidities (adjusted HR 3.49, 95 3.22–3.78).Conclusions:Critical care survivors have a higher risk of receiving psychotropic prescriptions than hospitalised patients, with a significant proportion receiving benzodiazepines and other hypnotics. Future research should focus on the requirement for and safety of psychotropic medicines in survivors of critical illness, to help guide policy for clinical practice

Markers characterizing corneal damage during aging of rat

Aging is a biological phenomenon that involves an increase of oxidative stress associated with gradual degradation of the structure and function of the cornea. Gender differences and subsequent deterioration of cornea is an interesting topic, especially yet few data are available concerning the impact of age, especially on the corneal. One hundred male and female Wistar albino rats ages 3, 6, 18, 24, and 30 months (n=10 equal for male and female) were used. At the time interval, cornea were investigated by light and transmission electron microscopy (TEM), immunohistochemistry of caspase 3 (casp3), glial fibrillar acidic protein(GFAP) and CD45 and  flow cytometry of DNA, bcl-2-like protein 4 (BAX), transforming growth factor beta (TGF-β) and Cd45 (lymphocyte common antigen). Light and TEM investigation  revealed apparent deterioration of atrophy of corneal epithelium with vesicular vacuolar degeneration, hyalinization of stromal collagen fibrils and swelling and degeneration of the endothelial lining the descemet's membrane. There was apparent loss of keratocytes within corneal stroma. Immunohistochemistry of casp 3 and CD45 were markedly increased manifesting cell damage. GFAP showed apparent reduction of innervation of corneal stroma and endothelium layer. Flow cytometry of DNA, Bax and TGF revealed increased apoptic cell death of cornea of 30M-old rats. We concluded that aging contributed to an apparent increase of cellular damage of different corneal region associated with alterations of cell markers
