coNP-complete and present two decision algorithms based on a semantical
characterization of definable relations as those preserved by isomorphisms of
substructures, the seco... | http://arxiv.org/abs/2303.17017v1 |
For $h \geq 1$, a $B_h$-set is a set of integers such that every integer $n$
has at most one representation in the form $n = a_{i_1} + \cdots + a_{i_h}$,
where $a_{i_j} \in A$ for all $j = 1,\ldots, h$ and $a_{i_1} \leq \ldots \leq
a_{i_h}$. The greedy $B_h$-set is the infinite set of nonnegative integers
$\{a_0(h), a_... | http://arxiv.org/abs/2310.14426v3 |
Digital twins are virtual representations of physical objects or systems used
for the purpose of analysis, most often via computer simulations, in many
engineering and scientific disciplines. Recently, this approach has been
introduced to computational medicine, within the concept of Digital Twin in
Healthcare (DTH). S... | http://arxiv.org/abs/2304.08190v1 |
Announcing the release v2 of the MORX (Millions of Optical-Radio/X-ray
Associations) catalogue which presents probable (40%-100% likelihood)
radio/X-ray associations, including double radio lobes, to optical objects over
the whole sky. Detections from all the largest radio/X-ray surveys to June 2023
are evaluated, thos... | http://arxiv.org/abs/2308.01507v3 |
We introduce a PDE-based node-to-element contact formulation as an
alternative to classical, purely geometrical formulations. It is challenging to
devise solutions to nonsmooth contact problem with continuous gap using finite
element discretizations. We herein achieve this objective by constructing an
approximate dista... | http://arxiv.org/abs/2302.13158v1 |
After the pandemic, humanity has been facing different types of challenges.
Social relationships, societal values, and academic and professional behavior
have been hit the most. People are shifting their routines to social media and
gadgets, and getting addicted to their isolation. This sudden change in their
lives has... | http://arxiv.org/abs/2308.06268v1 |
We present a computational framework for efficient learning, sampling, and
distribution of general Bayesian posterior distributions. The framework
leverages a machine learning approach for the construction of normalizing flows
for the general probability distributions typically encountered in Bayesian
uncertainty quant... | http://arxiv.org/abs/2310.04635v1 |
We show that very-long-baseline-interferometry (VLBI) observations of
supermassive black holes will allow us to test the fundamental principles of
General Relativity (GR). GR is based on the universality of gravity and
Einstein's equivalence principle (EEP). However, EEP is not a basic principle
of physics but an empir... | http://arxiv.org/abs/2303.13271v2 |
Multi-objective optimization is a ubiquitous problem that arises naturally in
many scientific and industrial areas. Network routing optimization with
multi-objective performance demands falls into this problem class, and finding
good quality solutions at large scales is generally challenging. In this work,
we develop a... | http://arxiv.org/abs/2308.08245v1 |
Studies of exoplanetary atmospheres have found no definite correlations
between observed high altitude aerosols and other system parameters. This could
be, in part, because of the lack of homogeneous exoplanet samples for which
specific parameters can be isolated and inspected. Here we present a set of
seven exoplanets... | http://arxiv.org/abs/2301.04174v1 |
The dynamics of a wobbling kink in a two-component coupled $\phi^4$ scalar
field theory (with an excited orthogonal shape mode) is addressed. For this
purpose, the vibration spectrum of the second order small kink fluctuation is
studied in order to find the corresponding vibration modes associated to the
first (longitu... | http://arxiv.org/abs/2310.15738v1 |
By classifying infinite-width neural networks and identifying the *optimal*
limit, Tensor Programs IV and V demonstrated a universal way, called $\mu$P,
for *widthwise hyperparameter transfer*, i.e., predicting optimal
hyperparameters of wide neural networks from narrow ones. Here we investigate
the analogous classific... | http://arxiv.org/abs/2310.02244v5 |
CellProfiler is a widely used software for creating reproducible, reusable
image analysis workflows without needing to code. In addition to the >90
modules that make up the main CellProfiler program, CellProfiler has a plugins
system that allows for the creation of new modules which integrate with other
Python tools or... | http://arxiv.org/abs/2306.01915v2 |
