Existing point cloud based 3D detectors are designed for the particular
scene, either indoor or outdoor ones. Because of the substantial differences in
object distribution and point density within point clouds collected from
various environments, coupled with the intricate nature of 3D metrics, there is
still a lack of... | http://arxiv.org/abs/2310.05699v1 |
Over the last decade, deep neural networks have achieved state of the art in
computer vision tasks. These models, however, are susceptible to unusual
inputs, known as adversarial examples, that cause them to misclassify or
otherwise fail to detect objects. Here, we provide evidence that the increasing
success of advers... | http://arxiv.org/abs/2306.07768v1 |
We report precision atmospheric spectroscopy of $CO_2$ using a laser
heterodyne radiometer (LHR) calibrated with an optical frequency comb. Using
the comb-calibrated LHR, we record spectra of atmospheric $CO_2$ near 1572.33
nm with a spectral resolution of 200 MHz using sunlight as a light source. The
measured $CO_2$ s... | http://arxiv.org/abs/2307.07441v1 |
Hybrid ionic-electronic conductors have the potential to generate memory
effects and neuronal behavior. The functionality of these mixed materials
depends on ion motion through thin polarizable channels. Here, we explore
different polarization models to show that the current and conductivity of
electrolytes is higher w... | http://arxiv.org/abs/2306.10214v3 |
Given its large plate scale of 21" / pixel, analyses of data from the TESS
space telescope must be wary of source confusion from blended light curves,
which creates the potential to attribute observed photometric variability to
the wrong astrophysical source. We explore the impact of light curve
contamination on the de... | http://arxiv.org/abs/2304.05706v1 |
We present an overview of the BLP Sentiment Shared Task, organized as part of
the inaugural BLP 2023 workshop, co-located with EMNLP 2023. The task is
defined as the detection of sentiment in a given piece of social media text.
This task attracted interest from 71 participants, among whom 29 and 30 teams
submitted syst... | http://arxiv.org/abs/2310.16183v2 |
In this paper, we investigate the achievable rate of a diffusive Molecular
Communication (MC) channel with fully absorbing receiver, which counts
particles absorbed along each symbol interval and resets the counter at every
interval (reset-counting). The MC channel is affected by a memory effect and
thus inter-symbol i... | http://arxiv.org/abs/2306.04261v1 |
The use of persona-grounded retrieval-based chatbots is crucial for
personalized conversations, but there are several challenges that need to be
addressed. 1) In general, collecting persona-grounded corpus is very expensive.
2) The chatbot system does not always respond in consideration of persona at
real applications.... | http://arxiv.org/abs/2310.06390v1 |
Objective: To investigate free radical scavenging potential of
thiocarbohydrazones derivatives for the discovery of antioxidant compounds of
synthetic origin. Method: Eighteen thiocarbohydrazones derivatives were
screened for antioxidant activities by using in vitro radical inhibition assay.
Cytotoxicity all derivative... | http://arxiv.org/abs/2310.00939v1 |
Intense geomagnetic storms can have a strong impact on the signals (termed
ionospheric scintillations) emitted by any global navigation satellite system
(GNSS). The paper reports the first studies of scintillations at the Indore
region on the NavIC signals due to the impact of the intense geomagnetic storm
event report... | http://arxiv.org/abs/2302.06181v1 |
Planets in young star clusters could shed light on planet formation and
evolution since star clusters can provide accurate age estimation. However, the
number of transiting planets detected in clusters was only $\sim 30$, too small
for statistical analysis. Thanks to the unprecedented high-precision
astrometric data pr... | http://arxiv.org/abs/2306.02610v2 |
Handwriting recognition is a challenging and critical problem in the fields
of pattern recognition and machine learning, with applications spanning a wide
range of domains. In this paper, we focus on the specific issue of recognizing
offline Arabic handwritten text. Existing approaches typically utilize a
combination o... | http://arxiv.org/abs/2307.15045v1 |
