We study the strong ill-posedness (norm inflation with infinite loss of regularity) for the nonlinear wave equation at every initial data in Wiener amalgam and Fourier amalgam spaces with negative regularity. In particular ...

Although stable hydrogen (delta H-2) and carbon (delta C-13) isotopic compositions of bird feathers have been increasingly used to understand the migration of birds through assignment of individuals to established isoscapes, ...

Theoretical explorations have revealed that quantum batteries can exploit quantum correlations to achieve faster charging, thus promising exciting applications in future technologies. Using NMR architecture, here we ...

We present a method for estimating seismic ambient noise sources by acoustic full waveform inversion of interstation cross-correlations. The method is valid at local scales for laterally heterogeneous media, and ambient ...

For a natural number m, a Lie algebra L over a field k is said to be of breadth type (0,m) if the co-dimension of the centralizer of every non-central element is m. In this article, we classify finite dimensional nilpotent ...

Sialic acid recognition and hydrolysis are essential parts of cellular function and pathogen infectivity. Neuraminidases are enzymes that detach sialic acid from sialosides, and their inhibition is a prime target for viral ...

A rational design of photocatalytic materials is essential to efficiently extract the photogenerated charge carriers, en route to achieving the desired chemical transformations. Here, we have incorporated the concept of ...

For a collection F of graphs, the F-CONTRACTION problem takes a graph G and an integer k as input and decides if G can be modified to some graph in F using at most k edge contractions. The F-CONTRACTION problem is NP-Complete ...

MoTe2 has a stable hexagonal semiconducting phase (2H) as well as two semimetallic phases with monoclinic (1T′) and orthorhombic (Td) structures. A structural change can thus be accompanied by a significant change in ...

Given a graph G on n vertices and two integers k and d, the Contraction(vc) problem asks whether one can contract at most k edges to reduce the vertex cover number of G by at least d. Recently, Lima et al. [JCSS 2021] ...
