| 1 | Diffusion weighted imaging: Technique and applications显示文摘Diffusion weighted imaging(DWI) is a method of signal contrast generation based on the differences in Brownian motion. DWI is a method to evaluate the molecular function and micro-architecture of the human body. DWI signal contrast can be quantified by apparent diffusion coefficient maps and it acts as a tool for treatment respon-se evaluation and assessment of disease progression. Ability to detect and quantify the anisotropy of diffusion leads to a new paradigm called diffusion tensor imaging(DTI). DTI is a tool for assessment of the organs with highly organised fibre structure. DWI forms an integral part of modern state-of-art magnetic resonance imaging and is indispensable in neuroimaging and oncology. DWI is a field that has been undergoing rapid technical evolution and its applications are increasing every day. This review article provides insights in to the evolution of DWI as a new imaging paradigm and provides a summary of current role of DWI in various disease processes. | Vinit Baliyan Chandan J Das Raju Sharma Arun Kumar Gupta | 2016 | World Journal of Radiology2016，8，9： | 18 |
| 2 | The joint automated repository for various integrated simulations (JARVIS) for data-driven materials design显示文摘The Joint Automated Repository for Various Integrated Simulations(JARVIS)is an integrated infrastructure to accelerate materials discovery and design using density functional theory(DFT),classical force-fields(FF),and machine learning(ML)techniques.JARVIS is motivated by the Materials Genome Initiative(MGI)principles of developing open-access databases and tools to reduce the cost and development time of materials discovery,optimization,and deployment. | Kamal Choudhary Kevin F.Garrity Andrew C.E.Reid Brian DeCost Adam J.Biacchi Angela R.Hight Walker Zachary Trautt Jason Hattrick-Simpers A.Gilad Kusne Andrea Centrone Albert Davydov Jie Jiang Ruth Pachter Gowoon Cheon Evan Reed Ankit Agrawal Xiaofeng Qian Vinit Sharma Houlong Zhuang Sergei V.Kalinin Bobby G.Sumpter Ghanshyam Pilania Pinar Acar Subhasish Mandal Kristjan Haule David Vanderbilt Karin Rabe Francesca Tavazza | 2020 | npj Computational Materials2020，，1： | 10 |
| 3 | High-throughput density functional perturbation theory and machine learning predictions of infrared,piezoelectric,and dielectric responses显示文摘Many technological applications depend on the response of materials to electric fields,but available databases of such responses are limited.Here,we explore the infrared,piezoelectric,and dielectric properties of inorganic materials by combining highthroughput density functional perturbation theory and machine learning approaches.We computeΓ-point phonons,infrared intensities,Born-effective charges,piezoelectric,and dielectric tensors for 5015 non-metallic materials in the JARVIS-DFT database.We find 3230 and 1943 materials with at least one far and mid-infrared mode,respectively. | Kamal Choudhary Kevin F.Garrity Vinit Sharma Adam J.Biacchi Angela R.Hight Walker Francesca Tavazza | 2020 | npj Computational Materials2020，，1： | 7 |
| 4 | Insight into point defects and impurities in titanium from first principles显示文摘Titanium alloys find extensive use in the aerospace and biomedical industries due to a unique combination of strength,density,and corrosion resistance.Decades of mostly experimental research has led to a large body of knowledge of the processingmicrostructure-properties linkages.But much of the existing understanding of point defects that play a significant role in the mechanical properties of titanium is based on semi-empirical rules.In this work,we present the results of a detailed self-consistent first-principles study that was developed to determine formation energies of intrinsic point defects including vacancies,selfinterstitials,and extrinsic point defects,such as,interstitial and substitutional impurities/dopants.We find that most elements,regardless of size,prefer substitutional positions,but highly electronegative elements,such as C,N,O,F,S,and Cl,some of which are common impurities in Ti,occupy interstitial positions. | Sanjeev K.Nayak Cain J.Hung Vinit Sharma S.Pamir Alpay Avinash M.Dongare William J.Brindley Rainer J.Hebert | 2018 | npj Computational Materials2018，，1： | 1 |

| 6 | Effects of particle size on the triboelectrification phenomenon in pharmaceutical excipients:Experiments and multi-scale modeling显示文摘Particle sizes play a major role to mediate charge transfer, both between identical and different material surfaces. The study probes into the probable mechanism that actuates opposite polarities between two different size fractions of the same material by analyzing the charge transfer patterns of two different sizes of microcrystalline cellulose(MCC). Quantum scale calculations confirmed alteration of charge transfer capacities due to variation of moisture content predicted by multiple surface and bulk analytical techniques. Discrete Element Method(DEM) based multi-scale computational models pertinent to predict charge transfer capacities were further implemented, and the results were in accordance to the experimental charge profiles. | Raj Mukherjee Vipul Gupta Shivangi Naik Saurabh Sarkar Vinit Sharma Prasad Peri Bodhisattwa Chaudhuri | 2016 | Asian Journal of Pharmaceutical Sciences2016，11，5： | 0 |
| 7 | Understanding the global dynamics of continuing unmet need for family planning and unintended pregnancy显示文摘1 Current status of unmet need for family planning Family planning is regarded as one of the major public health successes in the past 70 years.Worldwide,the contraceptive prevalence rate(CPR)for women of reproductive age rose from 28%in 1970 to 48%in 2019 and demand satisfied rose from 55 to 79%in the same time period(Haakenstad et al.,2022).Family planning offers both health and social benefits for women.It saves lives by pre-venting unintended,unwanted and unplanned pregnancies thereby reducing the need for abortions(that can often be unsafe and illegal)and also by reducing the probability of a woman’s death because of causes related to pregnancy and child-birth. | Justine Coulson Vinit Sharma Hua Wen | 2023 | China Population and Development Studies2023，7，1： | 0 |
| 8 | QT AG-Modules whose h-Pure-S-High Submodules Have Closure显示文摘A right module M over an associative ring R with unity is a QTAG-module if every finitely generated submodule of any homomorphic image of M is a direct sum of uniserial modules.This article considers the closure of h-pure-S-high submodules of QTAG-modules.Here,we determine all submodules S of a QTAG-module M such that each closure of h-pure-S-high submodule of M is h-pure-S^(-)-high in M^(-).A few results of this theme give a comparison of some elementary properties of h-pure-S-high and S-high submodules. | Mohd Noman ALI Vinit Kumar SHARMA Ayazul HASAN | 2024 | Journal of Mathematical Research with Applications2024，44，1： | 0 |
