Computer Science
Computation and Language
Commonsense Knowledge Bases (CSKB) Population, which aims at automatically
expanding knowledge in CSKBs with external resources, is an important yet hard
task in NLP. Fang et al. (2021a) proposed a CSKB Population (CKBP) framework
with an e...

With the extensive use of vision-language models in various downstream tasks,
evaluating their robustness is crucial. In this paper, we propose a benchmark
for assessing the robustness of vision-language models. We believe that a
robust mod...

Numerical Analysis
We studied an anisotropic modified Crouzeix--Raviart finite element method
for the rotational form of a stationary incompressible Navier--Stokes equation
with large irrotational body forces. We present an anisotropic H1 error
estimate fo...
The critical window in activated random walk on the complete graph

We consider an elementary model for self-organised criticality, the activated
random walk on the complete graph. We introduce a discrete time Markov chain as
follows. At each time step we add an active particle at a random vertex and let

Physics
General Relativity and Quantum Cosmology
It is well-known that the mass of a non-asymptotically flat spacetime cannot
be uniquely defined. Some mass formulas for the Kerr-AdS black hole have been
found and used in studying black hole thermodynamics. However, the derivations
usuall...

Convergence of the pruning processes of stable Galton-Watson trees

Mathematics
Probability
Since the work of Aldous and Pitman (1998), several authors have studied the
pruning processes of Galton-Watson trees and their continuous analogue L\'evy
trees. L\"ohr, Voisin and Winter (2015) introduced the space of bi-measure
$\mathbb{R...

Given a set F of graphs, we call a copy of a graph in
F an F-graph. The F-isolation number of a
graph G, denoted by ι(G,F), is the size of a smallest set D
of vertices of $...
3D hydrodynamic simulations of massive main-sequence stars. III. The
effect of radiation pressure and diffusion leading to a 1D equilibrium model

We present 3-D hydrodynamical simulations of core convection with a stably
stratified envelope of a \unit{25}{\Msun} star in the early phase of the
main-sequence. We use the explicit gas-dynamics code \code{PPMstar} which
tracks two fluids ...

In this work we consider variational properties of exact symplectic twist
maps T that act on the cotangent bundle of a torus, or on a ball bundle over
a sphere. An example of such a map is the well-known Birkhoff billiard map
