Methanol Synthesis from Simulated Bio-syngas: Experimental and Modeling Studies
Methanol is increasingly being considered as an alternative fuel due to its potential to reduce environmental pollution and its ability to be used directly in internal combustion engines without any engine modification. ... -
Rice transcription factors OsMADS2 and OsMADS4 regulate floret organ development: Deciphering their gene targets, traits and functions related to their unequal genetic redundancy
Organs in modern dicot flowers are positioned in concentric rings (whorls). The outermost whorl has green protective sepals, internal to which are showy petals, and the reproductive stamen and carpel whorls. Florets of ... -
A Monolithic Finite Element Formulation for Magnetohydrodynamics Involving a Compressible Fluid
This work develops a new monolithic finite-element-based strategy for Magnetohydrodynamics (MHD) involving a compressible fluid based on a continuous velocity-pressure formulation. The entire formula- tion is within a ... -
Neuronal complex bursts and network information transfer in the hippocampus are robust to biophysical heterogeneities
Biological entities must adopt mechanisms to override the impact of external perturbations to achieve stability and robustness. A crucial feature of biological systems is that they exhibit several forms of heterogeneities ... -
Opto-electronic Properties of a Few Dimensionally Controlled Hybrid Halides and Related Systems
To mitigate the adverse environmental effects of burning fossil fuels, it became necessary to explore alternative ‘clean’ renewable energy sources to meet the ever-increasing energy demands. While silicon-based solar cell ... -
Abstractions and Optimizations for Data-driven Applications Across Edge and Cloud

Photo magnetic Investigation and Magneto-structural Correlation of Switchable Molecular Magnetic Materials
Modern life without magnetic materials is almost impossible to imagine. Mobile phones, telecommunication, navigation, computer, television, credit cards, medical equipment, data storage devices, and sensors are an integral ... -
Raman Spectroscopy on Few layer graphene
Graphene is a two-dimensional allotrope of carbon exhibiting planer honeycomb lattice structure.1 A carbon atom in graphene makes three σ-bonds with the neighbouring atoms in the plane and one π-bond perpendicular to the ... -
An MLIR-Based High-Level Synthesis Compiler for Hardware Accelerator Design
The emergence of machine learning, image and audio processing on edge devices has motivated research towards power-efficient custom hardware accelerators. Though FPGAs are an ideal target for custom accelerators, the ... -
A Fundamental Investigation Of Discrete Liquid, Gas And Fines Flow In A Random Packed Bed Along With Applications
The discontinuous nature of liquid flow in a random packed bed is observed in many chemical engineering and metallurgical applications like blast furnace and heap leaching. So, to model the liquid flow in these systems, ... -
Beamforming and Target Tracking Methods for Active RF Phased Array Seekers
The end game guidance and control of an interceptor for neutralization of a hypersonic vehicle or a maneuvering aerial target is a challenging problem. This problem can be addressed in two ways: through faster autopilot ... -
Average Reward Actor-Critic with Deterministic Policy Search
The average reward criterion is relatively less studied as most existing works in the Reinforcement Learning literature consider the discounted reward criterion. There are few recent works that present on-policy average ... -
Exploring dissipation dynamics in low-dimensional superconductor
Technological advances in the past decade in fabricating two-dimensional superconducting materials with low disorder have enabled exploring many exciting phases. In recent times, two-dimensional superconductors have been ... -
