People involved in mass emergencies increasingly publish information-rich
contents in online social networks (OSNs), thus acting as a distributed and
resilient network of human sensors. In this work we present HERMES, a system
designed to e...
A non-relativistic Dirac equation: An application to photo ionization of
highly charged hydrogen-like ions

We investigate the role of relativity in photo ionization of hydrogen-like
ions by a laser pulse. For hydrogen, the wavelengths of the laser resides in
the weakly ultra violet region. For higher nuclear charges, the laser
parameters are sca...
Three Dimensional Gravity and Schramm-Loewner Evolution

High Energy Physics - Theory
The partition function of three dimensional gravity in the quantum regime is
dual to the Ising model when the central charge c=1/2. Mathematically, we
show that the three dimensional gravity can be described by Schramm-Loewner

General Mathematics
Plotting (ζ,U(x,y),V(x,y),x,y,z) and numerical calculations show that
ζ(s)=0 finitely many times in the Interval I with k roots in the
interval all of which are on the critical line which proves the Riemann
Hypothesis in...
The κ-Strongly Proper Forcing Axiom

We study methods to obtain the consistency of forcing axioms, and
particularly higher forcing axioms. We first force over a model with a
supercompact cardinal θ>κ to get the consistency of the forcing
axiom for κ-strongly...

In this note, we derive the closed form formulae for moments of Student's
t-distribution in the one dimensional case as well as in higher dimensions
through a unified probability framework. Interestingly, the closed form
expressions for the...
Axial vector transition form factors in holographic QCD and their
contribution to the anomalous magnetic moment of the muon

We evaluate axial vector transition form factors in holographic QCD models
that have been shown to reproduce well recent experimental and theoretical
results for the pion transition form factor. Comparing with L3 data on
$f_1\to\gamma\gamma...

We prove the first theorem on projections on general noncommutative
Lp-spaces associated with non-type I von Neumann algebras where 1≤p<∞. This is the first progress on this topic since the seminal

Tremendous recent literature show that associations between different brain

techniques, the...
Recovering from Biased Data: Can Fairness Constraints Improve Accuracy?

Multiple fairness constraints have been proposed in the literature, motivated
by a range of concerns about how demographic groups might be treated unfairly
by machine learning classifiers. In this work we consider a different
