We construct Quillen equivalent semi-model structures on the categories of
dg-Lie algebroids and L∞-algebroids over a commutative dg-algebra in
characteristic zero. This allows one to apply the usual methods of homotopical
algebra t...

In this paper we propose spatial filters for a linear regression model which
are based on the minimum-variance pseudo-unbiased reduced-rank estimation
(MV-PURE) framework. As a sample application, we consider the problem of
reconstruction o...

Planets interact with their host stars through gravity, radiation and
magnetic fields, and for those giant planets that orbit their stars within ~10
stellar radii (~0.1 AU for a sun-like star), star-planet interactions (SPI) are
observable ...

In this paper, we propose a micro hand gesture recognition system and methods
using ultrasonic active sensing. This system uses micro dynamic hand gestures
for recognition to achieve human-computer interaction (HCI). The implemented
system,...
A topological model for cellular motivic spectra

For any motivic E∞-ring spectrum A we construct an
equivalence ρ between the ∞-category of cellular motivic A-module
spectra and modules over an E1-algebra Θ in Z-graded spectr...

Making use of its smooth structure only, out of a connected oriented smooth
4-manifold a von Neumann algebra is constructed. It is geometric in the sense
that is generated by local operators and as a special four dimensional
phenomenon it...

Gaussian stochastic process (GaSP) has been widely used as a prior over
functions due to its flexibility and tractability in modeling. However, the
computational cost in evaluating the likelihood is O(n3), where n is the
number of obse...

We provide a Geometric Quantisation formulation of the AJ-conjecture for the
Teichm\"{u}ller TQFT, and we prove it in detail in the case of the knot
complements of 41 and 52. The conjecture states that the level-N

Lusztig used the symbol invariant to describe the Springer correspondence for
classical groups. Similarly, the fingerprint invariant can describe the
Kazhdan-Lusztig map. Both invariants pertain to rigid semisimple operators

We give a structure theorem for Boolean functions on the p-biased hypercube
which are ϵ-close to degree~d in L2, showing that they are close
to \emph{sparse juntas}. Our structure theorem implies that such functions are
