Bilinear based models are powerful and widely used approaches for Knowledge
Graphs Completion (KGC). Although bilinear based models have achieved
significant advances, these studies mainly concentrate on posterior properties
(based on evidence, e.g. symmetry pattern) while neglecting the prior
properties. In this paper... | http://arxiv.org/abs/2309.13834v1 |
In this paper, we address rare-event simulation for heavy-tailed L\'evy
processes with infinite activities. The presence of infinite activities poses a
critical challenge, making it impractical to simulate or store the precise
sample path of the L\'evy process. We present a rare-event simulation algorithm
that incorpor... | http://arxiv.org/abs/2309.13820v2 |
In this study, we reexamine the long-range interaction between two atoms
placed in an equilibrium thermal radiation environment. Employing the formalism
of quantum electrodynamics at finite temperatures, we derive an expression for
the thermal correction to the interaction potential and explore various
asymptotic behav... | http://arxiv.org/abs/2310.20351v2 |
We study the emergence of loose Hamilton cycles in subgraphs of random
hypergraphs. Our main result states that the minimum $d$-degree threshold for
loose Hamiltonicity relative to the random $k$-uniform hypergraph $H_k(n,p)$
coincides with its dense analogue whenever $p \geq n^{- (k-1)/2+o(1)}$. The
value of $p$ is ap... | http://arxiv.org/abs/2309.14197v1 |
In this paper we introduce a novel noise model for quantum measurements
motivated by an indirect measurement scheme with faulty preparation. Averaging
over random dynamics governing the interaction between the quantum system and a
probe, a natural, physical noise model emerges. We compare it to existing noise
models (u... | http://arxiv.org/abs/2305.19766v3 |
We present PopSED, a framework for the population-level inference of galaxy
properties from photometric data. Unlike the traditional approach of first
analyzing individual galaxies and then combining the results to determine the
physical properties of the entire galaxy population, we directly make the
population distri... | http://arxiv.org/abs/2309.16958v2 |
In this paper we have constructed inverse isospectral potentials for 1S0-nn
state by fitting the experimental SPS using Variational Monte-Carlo technique
in tandem with PFM technique. The isospectral potentials are obtained such that
the cost measure i.e., mean absolute error (MAE) between the obtained and
experimental... | http://arxiv.org/abs/2309.16780v1 |
Films of metal-insulator nanogranular composites M$_x$D$_{100-x}$ with
different composition and percentage of metal and dielectric phases (M = Fe,
Co, CoFeB; D = Al$_2$O$_3$, SiO$_2$, LiNbO$_3$; x $\approx$ 15-70 at.%) are
investigated by magnetic resonance in a wide range of frequencies (f = 7-37
GHz) and temperature... | http://arxiv.org/abs/2305.00551v1 |
Uranus and Saturn share similarities in terms of their atmospheric
composition, which is primarily made up of hydrogen and helium, as well as
their ring systems. Uranus has 13 known rings, which are divided into narrow
main rings, dusty rings, and outer rings. Unlike Saturn's broad ring system,
Uranus' inner narrow mai... | http://arxiv.org/abs/2309.11789v1 |
The observation of the Sagnac effect for massive material particles offers a
significant enhancement in sensitivity when compared to optical interferometers
with equal area and angular rotation velocity. For this reason, there have been
suggestions to employ solid-state interferometers that rely on semiconductors
and g... | http://arxiv.org/abs/2309.10497v3 |
A new method is proposed to predict the topological properties of
one-dimensional periodic structures in wave physics, including quantum
mechanics. From Bloch waves, a unique complex valued function is constructed,
exhibiting poles and zeros. The sequence of poles and zeros of this function is
a topological invariant t... | http://arxiv.org/abs/2309.12280v1 |
Large AI models (e.g., Dall-E, GPT4) have electrified the scientific,
technological and societal landscape through their superhuman capabilities.
These services are offered largely in a traditional web2.0 format (e.g.,
OpenAI's GPT4 service). As more large AI models proliferate (personalizing and
specializing to a vari... | http://arxiv.org/abs/2307.16562v1 |
