The procedure by means of which the occurrence time of an impending mainshock
can be identified by analyzing in natural time the seismicity in the candidate
area subsequent to the recording of a precursory Seismic Electric Signals (SES)

Unit-regularity and representability for semiartinian *-regular rings
July 31, 2019
Mathematics
Rings and Algebras
We show that any semiartinian *-regular ring R is unit-regular; if, in
addition, R is subdirectly irreducible then it admits a representation within
some inner product space. There is no proof of the result since a quoted result
is incorrec...

Selection is a fundamental task in exploratory analysis and visualization of
3D point clouds. Prior researches on selection methods were developed mainly
based on heuristics such as local point density, thus limiting their
applicability in ...

Differential Geometry
We prove that for a generic 3-dimensional integrable rolling distribution
of contact elements (excluding developable seed and isotropic developable
leaves) isometric correspondence of leaves of a general nature (independent of
the shape o...

We consider stochastic PDEs on the d-dimensional torus with fractional
Laplacian of parameter ρ∈(0,2], quadratic nonlinearity and driven by
space-time white noise. These equations are known to be locally subcritical,
and thus amena...

The detection of interesting patterns in large high-dimensional datasets is
difficult because of their dimensionality and pattern complexity. Therefore,
analysts require automated support for the extraction of relevant patterns. In

Probabilistic models are often trained by maximum likelihood, which
corresponds to minimizing a specific f-divergence between the model and data
distribution. In light of recent successes in training Generative Adversarial
Networks, alterna...
