an Artin algebra and $_BM_A$ a $B$-$A$-bimodule. We prove that there is a
triangle equivalence $D_{sg}(\Lambda) \cong D_{sg}(A)\coprod D_{sg}(B)$ between
the corresponding singularity categories if $_BM$ is semi-simple and $M_A$ is
projective... | http://arxiv.org/abs/2303.14091v1 |
In spite of being one of the smallest and wealthiest countries in the
European Union in terms of GDP per capita, Luxembourg is facing socio-economic
challenges due to recent rapid urban transformations. This article contributes
by approaching this phenomenon at the most granular and rarely analysed
geographical level -... | http://arxiv.org/abs/2307.09251v1 |
Accurate 3D tracking of hand and fingers movements poses significant
challenges in computer vision. The potential applications span across multiple
domains, including human-computer interaction, virtual reality, industry, and
medicine. While gesture recognition has achieved remarkable accuracy,
quantifying fine movemen... | http://arxiv.org/abs/2308.01088v1 |
We calculate the Wiener index of the zero-divisor graph of a finite
semisimple ring. We also calculate the Wiener complexity of the zero-divisor
graph of a finite simple ring and find an upper bound for the Wiener complexity
in the semisimple case. | http://arxiv.org/abs/2305.07405v2 |
In this work we study the self-integral of a function-measure kernel and its
importance on stochastic integration. A continuous-function measure kernel $K$
over $D \subset \mathbb{R}^{d}$ is a function of two variables which acts as a
continuous function in the first variable and as a real Radon measure in the
second. ... | http://arxiv.org/abs/2303.04282v1 |
As the early universe expands and cools the rates of the weak interactions
that keep neutrinos in thermal equilibrium with the matter and the related
rates of the reactions that inter-convert neutrons and protons decrease.
Eventually, these rates fall below the expansion rate -- they freeze out.
Likewise, the rates of ... | http://arxiv.org/abs/2301.12299v1 |
Multiview Self-Supervised Learning (MSSL) is based on learning invariances
with respect to a set of input transformations. However, invariance partially
or totally removes transformation-related information from the representations,
which might harm performance for specific downstream tasks that require such
informatio... | http://arxiv.org/abs/2306.16058v3 |
Diffusion generative models are promising alternatives for fast surrogate
models, producing high-fidelity physics simulations. However, the generation
time often requires an expensive denoising process with hundreds of function
evaluations, restricting the current applicability of these models in a
realistic setting. I... | http://arxiv.org/abs/2308.03847v1 |
We present a novel approach named OmniControl for incorporating flexible
spatial control signals into a text-conditioned human motion generation model
based on the diffusion process. Unlike previous methods that can only control
the pelvis trajectory, OmniControl can incorporate flexible spatial control
signals over di... | http://arxiv.org/abs/2310.08580v2 |
Information technology (IT) systems are vital for modern businesses, handling
data storage, communication, and process automation. Monitoring these systems
is crucial for their proper functioning and efficiency, as it allows collecting
extensive observational time series data for analysis. The interest in causal
discov... | http://arxiv.org/abs/2307.15678v1 |
We motivate then formulate a novel variant of the near-field reflector
problem and call it the near-field reflector problem with spatial restrictions.
Let $O$ be an anisotropic point source of light and assume that we are given a
bounded open set $U$. Suppose that the light emitted from the source at $O$ in
directions ... | http://arxiv.org/abs/2301.00845v1 |
Hydrodynamic phonon transport phenomena, like second sound, have been
observed in liquid Helium more than 50 years ago. More recently second sound
has been observed in graphite at over 200 K using transient thermal grating
techniques. In this work we explore the signatures of second sound in ultrafast
electron diffuse ... | http://arxiv.org/abs/2310.18793v2 |
This paper proposes a machine learning-based approach for detecting the
exploitation of vulnerabilities in the wild by monitoring underground hacking
forums. The increasing volume of posts discussing exploitation in the wild
calls for an automatic approach to process threads and posts that will
eventually trigger alarm... | http://arxiv.org/abs/2308.02581v1 |
