A search for dark matter axions with masses $>10 \mu eV/c^{2}$ has been
performed using the HAYSTAC experiment's squeezed state receiver to achieve
sub-quantum limited noise. This report includes details of the design and
operation of the experiment previously used to search for axions in the mass
ranges $16.96-17.12$ ... | http://arxiv.org/abs/2301.09721v2 |
We evaluated the capability of generative pre-trained transformers~(GPT-4) in
analysis of textual data in tasks that require highly specialized domain
expertise. Specifically, we focused on the task of analyzing court opinions to
interpret legal concepts. We found that GPT-4, prompted with annotation
guidelines, perfor... | http://arxiv.org/abs/2306.13906v1 |
The proposed polarized $^3$He$^{++}$ acceleration in RHIC and the future
Electron-Ion Collider will require about $2\times10^{11}$ ions in the source
pulse. A new technique had been proposed for production of high intensity
polarized $^3$He$^{++}$ ion beams. It is based on ionization and accumulation
of the $^3$He gas ... | http://arxiv.org/abs/2303.10409v3 |
We investigate the boundary between chemotaxis driven by spatial estimation
of gradients and chemotaxis driven by temporal estimation. While it is well
known that spatial chemotaxis becomes disadvantageous for small organisms at
high noise levels, it is unclear whether there is a discontinuous switch of
optimal strateg... | http://arxiv.org/abs/2310.10531v2 |
This paper considers multiple domination on Kneser graphs. We focus on
$k$-tuple dominating sets, $2$-packings and the associated graph parameters
$k$-tuple domination number and $2$-packing number. In particular, we compute
the $2$-packing number of Kneser graphs $K(3r-2,r)$ and in odd graphs we obtain
minimum $k$-tup... | http://arxiv.org/abs/2308.15603v2 |
An ultimate liquid xenon experiment would be limited in its dark matter
science reach by irreducible neutrino backgrounds, which are an exciting signal
in their own right. To achieve such sensitivity, other backgrounds that
currently plague these detectors must be better mitigated, and extreme care
must be taken in the... | http://arxiv.org/abs/2310.00722v2 |
Dependence on raw materials, especially in the mining sector, is a key part
of today's economy. Aggregates are vital, being the second most used raw
material after water. Digitally transforming this sector is key to optimizing
operations. However, supervision and maintenance (predictive and corrective)
are challenges l... | http://arxiv.org/abs/2310.16140v1 |
Citation recommendation (CR) models may help authors find relevant articles
at various stages of the paper writing process. Most research has dealt with
either global CR, which produces general recommendations suitable for the
initial writing stage, or local CR, which produces specific recommendations
more fitting for ... | http://arxiv.org/abs/2305.12190v1 |
Understanding model's sensitivity to its training data is crucial but can
also be challenging and costly, especially during training. To simplify such
issues, we present the Memory-Perturbation Equation (MPE) which relates model's
sensitivity to perturbation in its training data. Derived using Bayesian
principles, the ... | http://arxiv.org/abs/2310.19273v2 |
Knowledge graph reasoning (KGR) -- answering complex logical queries over
large knowledge graphs -- represents an important artificial intelligence task,
entailing a range of applications (e.g., cyber threat hunting). However,
despite its surging popularity, the potential security risks of KGR are largely
unexplored, w... | http://arxiv.org/abs/2305.02383v2 |
Large wildfires are becoming more frequent at temperate latitudes. Often,
fires generate massive convective columns that can carry solid particles (ash)
into the stratosphere. Like their meteorological counterparts, pyrocumulonimbus
(pyroCb) clouds can generate intense lightning storms. Recently, pyrogenic
lightning ha... | http://arxiv.org/abs/2310.06353v1 |
