2根据Lg波Q值反演得到的Hi-CLIMB项目西藏剖面地震衰减特征显示文摘利用可靠的双台站法研究了喜马拉雅—青藏大陆岩石层造山(Hi-CLIMB)项目西藏剖面的地壳Lg波的Q值。使用沿800km长的密间距的地震剖面记录的4次M≥5.5地震提取Lg波波谱。从2369种可能的配对中挑选出107对高质量的台站间的路径,使我们能够使用标准的双台站法进行Lg波Q值的测量。通过将这107个高质量台站间的Q0(1Hz的Lg波Q)值用做输入,由反演得出衰减特征的横向变化。该地区Q0的估计值范围是从88±5到165±15,羌塘地体的值最低,喜马拉雅山脉较低区域一些地方的值最高。最低值被认为是高泊松比、更高温度以及地壳部分熔融引起的。这些结果不含有任何可检测到的Q0值变化,不论在喜马拉雅—西藏碰撞带(即印度河—雅鲁藏布江缝合带)还是在大班公—怒江缝合带(BNSZ)都是如此。沿喜马拉雅地震探测项目剖面的一致低Q0值证明整个高原的地壳普遍存在部分熔融现象。C.Singh M.Shekar A.Singh R.K.Chadha 张尧(译) 徐沁(校) 吕春来(复校) 2012世界地震译丛2012,43,5:1

13InAs/InAsSb Avalanche Photodiode (APD) for applicaions in long-wavelength infrared region显示文摘A generic numerical model of a long-wavelength Avalanche Photodiode (APD) based on narrow bandgap semiconductor InAsSb on InAs substrate is reported for the first time. This model has been applied for theoretical characterization of a proposed N+ InAS/P-InAsSb avalanche photodiode structure for possible application in 2-5 μm wavelength region. The parameters such as gain,excess noise factor and their trade-off with variation of doping concentration and bias voltage have been estimated for the APD taking into account history-dependent theory of avalanche multiplication process. The LWIR APD is expected to find application in optical gas sensor and in future generation of optical communication system.P.K.Maurya H.Agarwal A.Singh P.Chakrabarti 2008Optoelectronics Letters2008,4,5:0
14Effect of various physical properties on the reflection coefficients of inhomogeneous waves at the stress-free surface of partially saturated soils induced by obliquely incident fast P-wave显示文摘Ghasemzadeh and Abounouri[1]developed a mathematical model of partially saturated soils that is solved using the potential method,which decomposes elastodynamics equations into two standard wave equations,a scalar wave equation for scalar potential and a vector wave equation for vector potential.In such a medium,four waves exist three longitudinal and one shear.Each fluid phase tortuous path is taken into account in this model.The inertial coupling between solid and fluid particles is consid-ered.Furthermore,both open-pore and sealed-pore boundaries are explored to investigate the reflection phenomenon at the surface of partially saturated soils.For both boundaries,the reflection coefficients of inhomogeneous waves at a partially saturated soil surface are found as a non-singular set of linear equations.All waves(both reflected and incident)in partially saturated soils are pronounced as inhomogeneous due to viscosity in pore fluids(i.e.,distinct directions of attenuation and propagation).The energy shares of reflected waves are determined using an energy matrix.A numerical example is used to determine the reflection coefficients and the distribution of incident energy among the various reflected waves.The effect of different physical features on reflection coefficients and incident energy partitioning is illustrated graphically.The conservation of incident energy at the surface of partially saturated soils is mathematically confirmed at all angles of incidence.M.Kumari M.S.Barak A.Singh M.Kumar 2022Journal of Ocean Engineering and Science2022,7,3:0
15Performance analysis of SiGe double-gate N-MOSFET显示文摘The major purpose of this paper is to find an alternative configuration that not only minimizes the limitations of single-gate(SG) MOSFETs but also provides the better replacement for future technology.In this paper,the electrical characteristics of SiGe double-gate N-MOSFET are demonstrated and compared with electrical characteristics of Si double-gate N-MOSFET.Furthermore,in this paper the electrical characteristics of Si doublegate N-MOSFET are demonstrated and compared with electrical characteristics of Si single-gate N-MOSFET.The simulations are carried out for the device at different operational voltages using Cogenda Visual TCAD tool.Moreover,we have designed its structure and studied both I_d-V_g characteristics for different voltages namely 0.05,0.1,0.5,0.8,1 and 1.5 V and I_d-V_d characteristics for different voltages namely 0.1,0.5,1 and 1.5 V at work functions 4.5,4.6 and 4.8 eV for this structure.The performance parameters investigated in this paper are threshold voltage,DIBL,subthreshold slope,GIDL,volume inversion and MMCR.A.Singh D.Kapoor R.Sharma 2017Journal of Semiconductors2017,38,4:0
16Renal Toxicity of Nickel,Sodium Lauryl Sulphate and Their Combination after Dermal Application in Guinea Pigs显示文摘The guinea pigs were dermally exposed to nickel(Ni).sodium lauryl sulphate(SLS)and in their combination for 7 and 14 days.The exposure to Ni and SLS produced changes in enzymes and lipid peroxidation in kidney.The exposure to Ni or SLS epicted slight changes while combined exposure to Ni plus SLS exhibited more degenerative changes in kidney.The result of the study suggests that industrial workers and/or populations exposed simultaneously to Ni and SLS produces more damage to kidney.A.K.MATHUR B.N.GUPTA A.SINGH S.SINGH RAVISHANKER 1993Biomedical and Environmental Sciences1993,6,3:0

18Development of IoT-Based Condition Monitoring System for Bridges显示文摘As of April 2019,India has 1,42,126 kilometres of National Highways and 67,368 kilometres of railway tracks that reach even the most remote parts of the country.Bridges are critical for both passenger and freight movement in the country.Because bridges play such an important part in the transportation system,their safety and upkeep must be prioritized.Manual Condition Monitoring has the disadvantage of being sluggish,unreliable,and inefficient.The Internet of Things has given structural monitoring a boost.Significant decreases in the cost of electronics and connection,together with the expansion of cloud platforms,have made it possible to collect large amounts of data remotely,aggregate it,and perform essential analysis to generate actionable insights.This research focuses on a scalable system for monitoring the state of bridges,such as vibration and loading,employing multimodal inputs,controllers,and Wi-Fi modules.The accelerometer and load cells were installed on the prototype,tested for a sample load(56.21 grams_(avg),590 grams_(max),and 147.66 grams_(rms))with induced vibration(5.87 m/sec^(2)_(avg),18 m/sec^(2)_(max),and 7.04 m/sec^(2)_(rms))that are processed,displayed on-board,and uploaded to ThingSpeak cloud service.This system will aid the maintenance personnel in remotely monitoring it.This system can send out notifications if any of these parameters exceeds their threshold value,allowing you to take preventive measures ahead of time.Sheetal A.Singh Suresh S.Balpande 2022Sound & Vibration2022,56,3:0
19Competition between axial anomaly and ferromagnetic ordering in Bi_(2-x)Fe_(x)Se_(3-x)S_(x) topological insulator:A study of magnetic and magnetotransport properties显示文摘The topological insulators Bi_(2-x)Fe_(x)Se_(3-x)S_(x) have been investigated by the dc-magnetization,magnetotransport and angle resolved photoemission spectroscopy(ARPES)techniques.With doping of Fe and S,a negative giant magneto-resistance(MR)is observed for parallel electric and magnetic fields(H||E).The MR behavior at lower magnetic field can be explained with the semi-classical theory whereas the MR behavior at higher field has been attributed to the axial anomaly.Interestingly,the system reached to the quantum limit at low magnetic field(~4.5T).The magnetic ordering can be explained with the presence of both the RKKY(surface)and van-Vleck(bulk)interaction.The ARPES study reveals that a surface gap is suppressed when the magnetic ordering changes from ferromagnetic to anti-ferromagnetic ordering.The ARPES study and the appearance of quantum oscillations(SdH)in the resistivity pattern reveal that the topological surface property is preserved with the co-doping of Fe and S.Rahul Singh Shiv Kumar A.Jain Mahima Singh Labanya Ghosh A.Singh Soma Banik A.Lakhani S.Patil E.F.Schwier K.Shimada S.M.Yusuf Sandip Chatterjee 2022Journal of Materiomics2022,8,3:0
