Achiral molecules can be made temporarily chiral by excitation with electric
fields, in the sense that an average over molecular orientations displays a net
chiral signal [Tikhonov et al., Sci. Adv. 8, eade0311 (2022)]. Here, we go
beyond the assumption of molecular orientations to remain fixed during the
excitation pr... | http://arxiv.org/abs/2310.11570v1 |
We construct a ${\rm KO}$-valued families index for a class of
$1|1$-dimensional Euclidean field theories. This realizes a conjectured cocycle
map in the Stolz--Teichner program. We further show that a bundle of spin
manifolds leads to a family of partially-defined $1|1$-Euclidean field
theories, yielding a cocycle ref... | http://arxiv.org/abs/2303.09207v1 |
AI-based code generators have become pivotal in assisting developers in
writing software starting from natural language (NL). However, they are trained
on large amounts of data, often collected from unsanitized online sources
(e.g., GitHub, HuggingFace). As a consequence, AI models become an easy target
for data poison... | http://arxiv.org/abs/2308.04451v3 |
We give explicit formulas for the Berezin symbols and the complex Weyl
symbols of the metaplectic representation operators by using the holomorphic
representations of the Jacobi group. Then we recover some known formulas for
the symbols of the metaplectic operators in the classical Weyl calculus, in
particular for the ... | http://arxiv.org/abs/2306.12947v1 |
We use semi-analytical models to study the effects of primordial black hole
(PBH) accretion on the cosmic radiation background during the epoch of
reionization ($z\gtrsim 6$). We consider PBHs floating in the intergalactic
medium (IGM), and located inside haloes, where star formation can occur. For
stars with a mass $\... | http://arxiv.org/abs/2310.01763v2 |
We obtain lower bound for the maximum distance between any three distinct
points in an affine lattice which are close to a helix with small curvature and
torsion. | http://arxiv.org/abs/2303.00545v1 |
Optically-pumped magnetometers are an important instrument for imaging
biological magnetic signals without the need for cryogenic cooling. These
magnetometers are presently available in the commercial market and utilize the
principles of atomic alignment or orientation, enabling remarkable sensitivity
and precision in ... | http://arxiv.org/abs/2308.12233v1 |
Large language models (LLMs) are capable to perform complex reasoning by
in-context learning (ICL) when provided with a few input-output demonstrations
(demos) and more powerful when intermediate reasoning steps ("chain of thoughts
(CoT)") of the demos are given. Is it necessary to use multi-demo in ICL? In
this paper,... | http://arxiv.org/abs/2303.08119v3 |
In order to better facilitate the need for continuous business process
improvement, the application of DevOps principles has been proposed. In
particular, the AB-BPM methodology applies AB testing and reinforcement
learning to increase the speed and quality of improvement efforts. In this
paper, we provide an industry ... | http://arxiv.org/abs/2303.10756v2 |
In this 4-page manuscript we discuss the problem of long-term AI Safety from
a Software Engineering (SE) research viewpoint. We briefly summarize long-term
AI Safety, and the challenge of avoiding harms from AI as systems meet or
exceed human capabilities, including software engineering capabilities (and
approach AGI /... | http://arxiv.org/abs/2304.14597v3 |
Innovative foundation models, such as GPT-4 and stable diffusion models, have
made a paradigm shift in the realm of artificial intelligence (AI) towards
generative AI-based systems. AI and machine learning (AI/ML) algorithms are
envisioned to be pervasively incorporated into the future wireless
communications systems. ... | http://arxiv.org/abs/2310.07312v3 |
It has become a consensus that autonomous vehicles (AVs) will first be widely
deployed on highways. However, the complexity of highway interchanges becomes
the bottleneck for deploying AVs. An AV should be sufficiently tested under
different highway interchanges, which is still challenging due to the lack of
available ... | http://arxiv.org/abs/2301.12738v1 |
Cloud systems have become increasingly popular in recent years due to their
flexibility and scalability. Each time cloud computing applications and
services hosted on the cloud are affected by a cloud outage, users can
experience slow response times, connection issues or total service disruption,
resulting in a signifi... | http://arxiv.org/abs/2305.18084v1 |
We show that the basic non-relativistic quantum formulations can be derived
from a least observability principle. The principle extends the least action
principle from classical mechanics by factoring in two assumptions. First, the
Planck constant defines the discrete amount of action a physical object needs
to exhibit... | http://arxiv.org/abs/2302.14619v7 |
