molecular state, respectively. Since the $\Omega_c^{*}$ was observed in the
$\Xi_c^{+}K^{-}$ invariant mass distribut... | http://arxiv.org/abs/2303.17770v1 |
We propose a sparse and privacy-enhanced representation for Human Pose
Estimation (HPE). Given a perspective camera, we use a proprietary motion
vector sensor(MVS) to extract an edge image and a two-directional motion vector
image at each time frame. Both edge and motion vector images are sparse and
contain much less i... | http://arxiv.org/abs/2309.09515v1 |
In this chapter we review our knowledge of our galaxy's cometary population
outside our Oort Cloud - exocomets and Interstellar Objects (ISOs). We start
with a brief overview of planetary system formation, viewed as a general
process around stars. We then take a more detailed look at the creation and
structure of exoco... | http://arxiv.org/abs/2303.17980v1 |
We study gas and metal outflow from massive galaxies in protocluster regions
at $z=3-9$ by using the results of the FOREVER22 simulation project. Our
simulations contain massive haloes with $M_{\rm h} \gtrsim 10^{13}~\rm
M_{\odot}$, showing high star formation rates of $> 100~\rm M_{\odot}~yr^{-1}$
and hosting supermas... | http://arxiv.org/abs/2309.05307v1 |
In this Working Paper we analyse computational strategies for using
aggregated spatio-temporal population data acquired from telecommunications
networks to infer travel and movement patterns between geographical regions.
Specifically, we focus on hour-by-hour cellphone counts for the SA-2
geographical regions covering ... | http://arxiv.org/abs/2303.17758v1 |
Context. Many Internet content platforms, such as Spotify and YouTube,
provide their services via both native and Web apps. Even though those apps
provide similar features to the end user, using their native version or Web
counterpart might lead to different levels of energy consumption and
performance. Goal. The goal ... | http://arxiv.org/abs/2308.16734v1 |
We study the top-$k$ selection problem under the differential privacy model:
$m$ items are rated according to votes of a set of clients. We consider a
setting in which algorithms can retrieve data via a sequence of accesses, each
either a random access or a sorted access; the goal is to minimize the total
number of dat... | http://arxiv.org/abs/2301.13347v2 |
By [6], a minimal group $G$ is called $z$-minimal if $G/Z(G)$ is minimal. In
this paper, we present the $z$-Minimality Criterion for dense subgroups with
some applications to topological matrix groups. For a locally compact group
$G$, let $\operatorname{Inn}(G)$ be the group of all inner automorphisms of
$G,$ endowed w... | http://arxiv.org/abs/2309.17065v2 |
Object search is a challenging task because when given complex language
descriptions (e.g., "find the white cup on the table"), the robot must move its
camera through the environment and recognize the described object. Previous
works map language descriptions to a set of fixed object detectors with
predetermined noise ... | http://arxiv.org/abs/2309.07276v1 |
Classical motion planning for robotic manipulation includes a set of general
algorithms that aim to minimize a scene-specific cost of executing a given
plan. This approach offers remarkable adaptability, as they can be directly
used off-the-shelf for any new scene without needing specific training
datasets. However, wi... | http://arxiv.org/abs/2309.11414v1 |
KZnBi was discovered recently as a new three-dimensional Dirac semimetal with
a pair of bulk Dirac fermions in contrast to the $\mathbb{Z}_2$ trivial
insulator reported earlier. In order to address this discrepancy, we have
performed electronic structure and topological state analysis of KZnBi using
the local, semiloca... | http://arxiv.org/abs/2309.05461v2 |
Redox potentials of electron transfer reactions are of fundamental importance
for the performance and description of electrochemical devices. Despite decades
of research, accurate computational predictions for the redox potential of even
simple metals remain very challenging. Here we use a combination of first
principl... | http://arxiv.org/abs/2309.13217v2 |
In this article, we have studied the nuclear modification factor measured in
Pb-Pb collisions ($R_{PbPb}$) for $\pi^{\pm}$, $K^{\pm}$, $p+\bar{p}$, $K^{*0}
+ \bar{K^{*0}}$, $\phi$ and in p-Pb collisions ($R_{pPb}$) for $\pi^{\pm}$,
$K^{\pm}$, $p+\bar{p}$ at Large hadron collider (LHC) energy of $\sqrt{s_{NN}}$
= 5.02 T... | http://arxiv.org/abs/2309.17071v1 |
