Tuning of electrical and magnetic properties in nanocomposites of conductive LaNiO3 and transition metal oxides
The discovery of new composites by integrating materials of different physical properties with optimal control is of immense interest to researchers at present. Today, there are several composites being used for several ... -
Adaptively Secure Primitives in the Random Oracle Model
Adaptive security embodies one of the strongest notions of security that allows an adversary to corrupt parties at any point during protocol execution and gain access to its internal state. Since it models reallife situations ... -
Rotational Temperature Measurement in Hypersonic Shock Tunnel using Tunable Diode Laser Absorption Spectroscopy
Atmospheric entry of a spacecraft is considered as one of the critical phases in any planetary mission. Although it lasts only for a few minutes, rapid heating and deceleration can cause severe problems to the spacecraft. ... -
Structured Regularization Through Convex Relaxations Of Discrete Penalties
Motivation. Empirical risk minimization(ERM) is a popular framework for learning predictive models from data, which has been used in various domains such as computer vision, text processing, bioinformatics, neuro-biology, ... -
Mechanics of Martensitic Phase transformation in shape memory alloys Experiments and modelling
Thermally activated NiTi based Shape Memory Alloys (SMAs) are of tremendous practical interest as actuators in varied engineering applications owing to its characteristic Martensitic Phase Transformation (MPT). The MPT in ... -
A geochemical and Nd-Sr-Ca isotopic study of silicate weathering, crustal recycling and petrogenesis of carbonatites
Weathering of silicate rocks releases cations and anions which are transported to the oceans by rivers where calcium carbonate precipitates from the seawater. This process results in the net consumption of atmospheric ... -
Deep Visual Representations: A study on Augmentation, Visualization, and Robustness
Deep neural networks have resulted in unprecedented performances for various learning tasks. Particularly, Convolutional Neural Networks (CNNs) are shown to learn representations that can efficiently discriminate hundreds ... -
Integrated optic devices on thin film lithium niobate for few-mode optical communications
Mode division multiplexing is a remarkable strategy to meet the explosively increasing bandwidth requirements in optical communication systems and interconnects. This scheme harnesses the orthogonality of modes to scale ... -
Multisource Subnetwork Level Transfer in Deep CNNs Using Bank of Weight Filters
The convolutional neural networks (CNNs) have become the most successful models for many pattern recognition problems in the areas of computer vision, speech, text and others. One concern about CNNs has always been their ... -
Protein Adsorption on Gold Nanoparticle and Protein Surfaces Probed by Second Harmonic Light Scattering
Second harmonic light scattering (SHLS) is a highly sensitive technique to probe reactions at interfaces/surfaces because of symmetry breaking at the interface/surface produces a large surface polarization which gives ... -
A Trusted-Hardware Backed Secure Payments Platform for Android
Digital payments using personal electronic devices have been steadily gaining in popularity for the last few years. While digital payments using smartphones are very convenient, they are also more susceptible to security ... -
Spray Interaction with Supersonic Crossflow
The flow residence time in a scramjet combustor is of the order of a millisecond (10−3s). High energy density liquid fuels are the energy carriers of choice in scramjet engines, however liquid fuels must be atomized, ... -
Molecular insights into AMP-activated protein kinase (AMPK)-mediated regulation of anoikis resistance
Our study identifies negative cross-talk between AMPK and two important cellular kinases, Akt and Erk. AMPK-mediated inhibition of these two kinases promotes survival of cancer cells in the matrix-deprived condition. ... -
Stimulus statistics and HCN current mediated resonance sets the scale of input-output mapping in Stellate cells of the Medial Entorhinal Cortex
The functional significance of the computations performed by Stellate cells of the Medial Entorhinal Cortex, proven time and again, makes them insightful, yet intriguing. The gradients of the intrinsic properties of these ... -
Stationary diesel exhaust treatment by blending discharge plasma/ozone with industry wastes: a study on abatement of NOx and THC
Increased usage of fossil fuels, especially diesel, has made a large impact on the environment in the form of rise in global temperature, increased acidity in the rain water, decreased yield in vegetation and numerous ... -
Spectral Analysis of Wave Motion in Nonlocal Continuum Theories of Elasticity
Traditionally, in solid mechanics, classical continuum theories of elasticity have been an important tool in the examinations of behaviour of solids under external loads. However, due to absence of length scale information ... -
The role of quantum fluctuations in the t-J model: Implications for cuprate superconductors
The physics of strongly correlated electron systems is among the central problems of condensed matter physics. One of the outstanding problems in this category is that of the high-Tc superconductivity obtained by doping ... -
Development of a Flexible Actuator and Motion Planning for Endoscopic Robots
Endoscopy is a procedure by which a long flexible device called the `endoscope' is inserted into a patient's gastro-intestinal(GI) tract primarily for diagnosis. An endoscope is typically equipped with a camera, ... -
Regulation of auxin response by UBIQUITIN-SPECIFIC PROTEASE14/ TARANI in Arabidopsis thaliana
The genetic pathway regulating auxin response in Arabidopsis is well established and provides us a framework to assess whether TNI belongs to this pathway. The total number of lateral roots is taken as a read-out of auxin ... -
Carbon-Carbon and Carbon Heteroatom Bond Forming Reactions: From Organocatalysts to Quantum Dots
Butenolides containing stereogenic centers on the ring, are commonly encountered structural motifs, found in many natural products. Consequently, there has been considerable interest in efficient and stereoselective ...
