New Paper Published in Nature Communications titled, “Exact exchange-correlation potentials from ground-state electron densities”
Published titled Exact potentials electron densities
2019/10/10
The quest for accurate exchange-correlation functionals has long remained a grand challenge in density functional theory (DFT), as it describes the many-electron quantum mechanical behavior through a ...
Consider a point mass falling vertically on an infinitely heavy
horizontal plate which oscillates periodically with period 2π in the vertical direction
and interacts with the particle by the l...

2015/8/17
In this paper, we prove a differential Harnack inequality for positive
solutions of time-dependent heat equations with potentials. We also prove a gradient
estimate for the positive solution o...

In this paper, we derive a general evolution formula for possible Harnack quantities. As a consequence, we prove several differential Harnack inequalities
for positive solutions of backward hea...

The characterisation of seismic sources with timereversed wave fields is developing into a standard technique
that has already been successful in numerous applications.

The incidence of diabetes mellitus and cardiovascular diseases is increasing at a worrisome rate globally. Diabetes mellitus is known to occur due to high blood glucose levels, caused by defects in in...
The Nexus Land-Use model version 1.0, an approach articulating biophysical potentials and economic dynamics to model competition for land-use
Demand for food. Biomass energy Forest protection Land use Model equation biophysics
2014/12/10
Interactions between food demand, biomass energy and forest preservation are driving both food prices and land-use changes, regionally and globally. This study presents a new model called Nexus Land-U...
