Most state-of-the-art approaches for namedentity recognition (NER) use semi supervised information in the form of word clusters and lexicons. Recently neural network-based language models have been explored, as they as a byproduct generate highly informative vector representations for words, known as word embeddings. In this paper we present two(More)
Peer-to-peer (P2P) systems are typically divided into those that centralize lookup functionality in a single location and those that distribute the lookup operation across the set of participating hosts. The former approach can offer constant time lookup latency, but is more expensive to scale and suffers from single points of failure. In contrast, the(More)
OBJECTIVE The objective of the study was to assess the efficacy and safety of second-generation antipsychotics olanzapine and risperidone vs. haloperidol in patients of delirium admitted to medical and surgical wards. METHODS Prospective follow-up single-blind randomized controlled trials were performed. Consecutive patients with delirium referred to the(More)
The protozoan parasite Toxoplasma gondii enhances the sexual attractiveness of infected male rats and attenuates the innate fear of cat odour in infected individuals. These behavioural changes plausibly lead to greater transmission of parasites through sexual and trophic routes, respectively. Testosterone, a testicular steroid, is known to reduce fear and(More)
Three Indian soybean genotypes, namely, Kalitur, Hara soya and NRC37 with black, green and yellow colored seed coat respectively were gamma irradiated at a dose of 0.5, 2.0, and 5.0 kGy. The total isoflavones and total phenol content (TPC) in all the genotypes increased significantly at a dose of 0.5 and 2 kGy respectively. The anthocyanin content was high(More)
Nanotechnology is a fast growing field that provides for the development of materials that have new dimensions, novel properties, and a broader array of applications. Various scientific groups are keen about this technology and are devoting themselves to the development of more, new, and better nanomaterials. In the near future, expectations are that no(More)
The purpose of this work was to determine the nature of long and short-range forces governing protein aggregation kinetics at low and high concentrations for a monoclonal antibody (IgG1) and a dual-variable-domain immunoglobulin (DVD-Ig). Protein-protein interactions (PPI) were studied under dilute conditions by utilizing the methods of static (B(22)) and(More)
The exact mechanism of the modulation of chemical potential of proteins by polyols is not yet well understood. Present study investigates the role of hydrophobicity of polyols, and their impact on water activity and/or surface tension, in determining their stabilization/destabilization potential. Results with ribose and methyl-glucose show that the enhanced(More)
A net-based, decision support system for diagnostic assessment and management of psychiatric disorders, developed as part of a telepsychiatry service, which aims to deliver mental health care to underserved population of remote areas in India is described. This paper presents the development and preliminary results of diagnostic validation of the(More)
Three compounds, namely the interesting biflavanonol GB-2(naringenin 1-3, 11-8-dihydroquercetin, 1), 1-4',1-5,11-5,1-7,11-7-pentahydroxyflavanone(l-3,11-8)chromone [naringenin-(3 -8) 5,7-dihydroxychromone, 21 and stigmasterol, have been isolated from the leaves of Cratoxylum neriifolium Kurz. Compounds 1 and 2 show rotameric behavior due to the presence of(More)
