B-cell repertoires are characterized by a diverse set of receptors of
distinct specificities generated through two processes of somatic
diversification: V(D)J recombination and somatic hypermutations. B cell clonal
families stem from the sa...

We study single-field slow-roll inflation embedded in Palatini F(R) gravity
where F(R) grows faster than R2. Surprisingly, the consistency of the
theory requires the Jordan frame inflaton potential to be unbounded from below.

Diffusion models have shown a great ability at bridging the performance gap
between predictive and generative approaches for speech enhancement. We have
shown that they may even outperform their predictive counterparts for
non-additive corr...
Universal truth of operator statements via ideal membership

We introduce a framework for proving statements about linear operators by
verification of ideal membership in a free algebra. More specifically,
arbitrary first-order statements about identities of morphisms in preadditive
semicategories ca...

Emission properties of compact astrophysical objects such as Neutron stars
(NSs) are associated with crucial astronomical observables. In the current
work, we obtain the mass, pressure profiles of the non-rotating NSs using the
modified Tol...
As a phenomenon encompassing measurement incompatibility and Bell
nonlocality, quantum contextuality is not only central to our understanding of
quantum mechanics, but also an essential resource in many quantum information
processing tasks....

In a system with one conserved charge the charge diffusion is modified by
non-linear self-interactions within an effective field theory (EFT) of
diffusive fluctuations. We include the slowest ultraviolet (UV) mode,
constructing a UV-regulat...

We investigate the effect of a first-order electroweak phase transition
(FOEWPT), which is one of the prerequisites for electroweak baryogenesis, on
the thermal relic abundance of the dark matter (DM) that freezes out before the

Understanding the continuum limit of a theory of discrete random geometries
is a beautiful but difficult challenge. In this optic, we review here the
insights that can be obtained for Causal Dynamical Triangulations (CDT) by
employing the L...
