In this paper, we show that for each lattice basis, there exists an
equivalent basis which we describe as ``strongly reduced''. We show that bases
reduced in this manner exhibit rather ``short'' basis vectors, that is, the
length of the $i$th basis vector of a strongly reduced basis is upper bounded
by a polynomial fac... | http://arxiv.org/abs/2304.12135v2 |
Vision foundation models such as Contrastive Vision-Language Pre-training
(CLIP) and Segment Anything (SAM) have demonstrated impressive zero-shot
performance on image classification and segmentation tasks. However, the
incorporation of CLIP and SAM for label-free scene understanding has yet to be
explored. In this pap... | http://arxiv.org/abs/2306.03899v2 |
Static analysis tools are traditionally used to detect and flag programs that
violate properties. We show that static analysis tools can also be used to
perturb programs that satisfy a property to construct variants that violate the
property. Using this insight we can construct paired data sets of unsafe-safe
program p... | http://arxiv.org/abs/2307.12465v1 |
We present a catalog of distances for 19544 K giants drawn from LAMOST DR8.
Most of them are located in the halo of the Milky Way up to ~120~kpc. There are
15% K giants without SDSS photometry, for which we supplements with Pan-STARRS1
(PS1) photometry calibrated to SDSS photometric system. The possible
contamination o... | http://arxiv.org/abs/2305.03311v1 |
Competitive influence maximization has been studied for several years, and
various frameworks have been proposed to model different aspects of information
diffusion under the competitive environment. This work presents a new gameboard
for two competing parties with some new features representing loyalty in social
netwo... | http://arxiv.org/abs/2303.01850v1 |
We deal with the problem of optimal estimation of the linear functionals
constructed from the missed values of a continuous time stochastic process
$\xi(t)$ with periodically stationary increments at points $t\in[0;(N+1)T]$
based on observations of this process with periodically stationary noise. To
solve the problem, ... | http://arxiv.org/abs/2307.02676v1 |
Accurate high-speed flow simulations of practical interest require numerical
methods with high-resolution properties. In this paper, we present an extension
and demonstration of the high-accuracy Gradient-based reconstruction and
$\alpha$-damping schemes introduced by Chamarthi (2022) [1] for simulating
high-speed flow... | http://arxiv.org/abs/2303.10785v1 |
As students pursue a bachelor's degree in physics, they may ponder over which
area to specialize in, such as theory, computation, or experiment. Often
students develop preferences and dislikes, but it's unclear when this
preference solidifies during their undergraduate experiences. To get a better
understanding, we int... | http://arxiv.org/abs/2306.15023v1 |
Graphs consisting of vocal nodes ("the vocal minority") and silent nodes
("the silent majority"), namely VS-Graph, are ubiquitous in the real world. The
vocal nodes tend to have abundant features and labels. In contrast, silent
nodes only have incomplete features and rare labels, e.g., the description and
political ten... | http://arxiv.org/abs/2302.00873v3 |
A path independent measure in order parameter space is introduced such that,
when integrated along any closed contour in a three dimensional nematic phase,
it yields the topological charge of any line defects encircled by the contour.
A related measure, when integrated over either closed or open surfaces, reduces
to kn... | http://arxiv.org/abs/2308.04496v1 |
Theoretical and computational frameworks of modern science are dominated by
binary structures. This binary bias, seen in the ubiquity of pair-wise networks
and formal operations of two arguments in mathematical models, limits our
capacity to faithfully capture irreducible polyadic interactions in
higher-order systems. ... | http://arxiv.org/abs/2301.07494v1 |
