different computational limits. A detection-recovery gap for PDS was
substantiated in the form of a pr... | http://arxiv.org/abs/2306.17719v1 |
Cloud computing platforms are progressively adopting Field Programmable Gate
Arrays to deploy specialized hardware accelerators for specific computational
tasks. However, the security of FPGA-based bitstream for Intellectual Property,
IP cores from unauthorized interception in cloud environments remains a
prominent con... | http://arxiv.org/abs/2309.16282v2 |
Current digital computers are about to hit basic physical boundaries with
respect to integration density, clock frequencies, and particularly energy
consumption. This requires the application of new computing paradigms, such as
quantum and analog computing in the near future. Although neither quantum nor
analog compute... | http://arxiv.org/abs/2309.05598v1 |
The violation of detailed balance poses a serious problem for the majority of
current quasiclassical methods for simulating nonadiabatic dynamics. In order
to analyze the severity of the problem, we predict the long-time limits of the
electronic populations according to various quasiclassical mapping approaches,
by app... | http://arxiv.org/abs/2309.04686v3 |
Process simulation is gaining attention for its ability to assess potential
performance improvements and risks associated with business process changes.
The existing literature presents various techniques, generally grounded in
process models discovered from event log data or built upon deep learning
algorithms. These ... | http://arxiv.org/abs/2303.17879v4 |
We prove the generalized second law (GSL) for higher curvature gravity
theories when the matter sector is non-minimally coupled. The validity of our
proof is in the regime of linearized fluctuations about equilibrium black
holes, which is the same regime as considered in the previous proofs by Wall
and Sarkar. These pr... | http://arxiv.org/abs/2309.12782v1 |
LLMs are increasingly powerful and widely used to assist users in a variety
of tasks. This use risks the introduction of LLM biases to consequential
decisions such as job hiring, human performance evaluation, and criminal
sentencing. Bias in NLP systems along the lines of gender and ethnicity has
been widely studied, e... | http://arxiv.org/abs/2309.08902v3 |
Quantum enhanced optimization of classical cost functions is a central theme
of quantum computing due to its high potential value in science and technology.
The variational quantum eigensolver (VQE) and the quantum approximate
optimization algorithm (QAOA) are popular variational approaches that are
considered the most... | http://arxiv.org/abs/2308.00044v2 |
The $2$-adic complexity has been well-analyzed in the periodic case. However,
we are not aware of any theoretical results on the $N$th $2$-adic complexity of
any promising candidate for a pseudorandom sequence of finite length $N$ or
results on a part of the period of length $N$ of a periodic sequence,
respectively. He... | http://arxiv.org/abs/2309.12769v1 |
In this paper, we introduce a new discretization of the Gaussian curvature on
surfaces, which is defined as the quotient of the angle defect and the area of
some dual cell of a weighted triangulation at the conic singularity. A discrete
uniformization theorem for this discrete Gaussian curvature is established on
surfa... | http://arxiv.org/abs/2309.05215v1 |
In this paper, we show that any globally hyperbolic space-time admits at
least one globally defined distance-like function, which is a viscosity
solution to the Lorentzian eikonal equation. According to whether the time
orientation is changed, we divide the set of viscosity solutions into some
subclasses. We show if th... | http://arxiv.org/abs/2309.15006v4 |
The cerebrospinal fluid (CSF) of 19 subjects who received a clinical
diagnosis of Alzheimer's disease (AD) as well as of 5 pathological controls
have been collected and analysed by Raman spectroscopy (RS). We investigated
whether the raw and preprocessed Raman spectra could be used to distinguish AD
from controls. Firs... | http://arxiv.org/abs/2309.03664v1 |
In this paper, we introduce Interval Real Logic (IRL), a two-sorted logic
that interprets knowledge such as sequential properties (traces) and event
properties using sequences of real-featured data. We interpret connectives
using fuzzy logic, event durations using trapezoidal fuzzy intervals, and fuzzy
temporal relatio... | http://arxiv.org/abs/2303.17892v1 |
Estimating metallicity of classical Cepheids is of prime importance for
studying metallicity effect on stellar evolution, chemical evolution of
galaxies, and ultimately its impact on period-luminosity relation used in the
extragalactic distance scale. We aim at establishing new empirical relations
for estimating the ir... | http://arxiv.org/abs/2301.00229v2 |
