This note describes a new efficient bit-slice implementation DenseQMC of the
Quine-McCluskey algorithm for finding all prime implicants of a Boolean
function in the dense case. It is practically feasible for n <= 23 when run on
a common laptop or for n <= 27 when run on a server with 1 TiB RAM.
This note also outline... | http://arxiv.org/abs/2302.10083v1 |
This paper proposes a stochastic framework to evaluate the performance of
public transit systems under short random service suspensions. We aim to derive
closed-form formulations of the mean and variance of the queue length and
waiting time. A bulk-service queue model is adopted to formulate the queuing
behavior in the... | http://arxiv.org/abs/2301.00918v1 |
This paper describes our participation in the shared task of hate speech
detection, which is one of the subtasks of the CERIST NLP Challenge 2022. Our
experiments evaluate the performance of six transformer models and their
combination using 2 ensemble approaches. The best results on the training set,
in a five-fold cr... | http://arxiv.org/abs/2303.09823v1 |
Modern computing has enhanced our understanding of how social interactions
shape collective behaviour in animal societies. Although analytical models
dominate in studying collective behaviour, this study introduces a deep
learning model to assess social interactions in the fish species Hemigrammus
rhodostomus. We compa... | http://arxiv.org/abs/2302.06839v2 |
A subset $M$ of a separable Hilbert space $H$ is $\ell^1$-bounded if there
exists a Riesz basis $\mathcal{F} = \{e_n\}_{n \in \mathbb{N}}$ for $H$ such
that $\sup_{x \in M} \sum_{n \in \mathbb{N}} |\langle x, e_n\rangle| < \infty.$
A similar definition for $\ell^1$-frame-bounded sets is made by replacing Riesz
bases wi... | http://arxiv.org/abs/2307.05536v1 |
The axion is a hypothetical particle, a promising candidate for dark matter,
and a solution to the strong CP problem. Axion haloscope search experiments
deal with a signal power comparable to noise uncertainty at millikelvin
temperature. We use a flux-driven Josephson parametric amplifier (JPA) with the
aim of approach... | http://arxiv.org/abs/2304.04378v2 |
The formation mechanism of AM CVn binary has not been well understood yet.
Accurate measurements of the mass transfer rate can help to determine the
formation mechanism. But unfortunately such observation by electromagnetic
means is quite challenging. One possible formation channel of AM CVn binary is
a semi-detached w... | http://arxiv.org/abs/2302.08814v3 |
Reciprocal recommender system (RRS), considering a two-way matching between
two parties, has been widely applied in online platforms like online dating and
recruitment. Existing RRS models mainly capture static user preferences, which
have neglected the evolving user tastes and the dynamic matching relation
between the... | http://arxiv.org/abs/2306.14712v1 |
Ethics have become an urgent concern for data science research, practice, and
instruction in the wake of growing critique of algorithms and systems showing
that they reinforce structural oppression. There has been increasing desire on
the part of data science educators to craft curricula that speak to these
critiques, ... | http://arxiv.org/abs/2305.02420v1 |
Photosensitive gaseous detectors with a simple photoelectron multiplication
mechanism of resistive plate chambers (RPCs) are expected to have both a large
photocoverage and an excellent time resolution and to be low-cost. To
demonstrate the time resolution of the RPC-based photodetectors, we built a
prototype detector ... | http://arxiv.org/abs/2302.12694v2 |
The absolute mass of neutrinos and their nature are presently unknown.
Aggregate matter has a coherent weak charge leading to a repulsive interaction
mediated by a neutrino pair. Near its range at micron distances the virtual
neutrinos are non-relativistic, giving a distinct behavior for Dirac versus
Majorana mass term... | http://arxiv.org/abs/2306.00767v2 |
In crowdsourcing systems, requesters publish tasks, and interested workers
provide answers to get rewards. Worker anonymity motivates participation since
it protects their privacy. Anonymity with unlinkability is an enhanced version
of anonymity because it makes it impossible to ``link'' workers across the
tasks they p... | http://arxiv.org/abs/2302.03941v1 |
Temperature is a hallmark parameter influencing almost all magnetic resonance
properties (e.g., T\textsubscript{1}, T\textsubscript{2}, proton density,
diffusion and more). In the pre-clinical setting, temperature has a large
influence on animal physiology (e.g., respiration rate, heart rate, metabolism,
cellular stres... | http://arxiv.org/abs/2305.01129v1 |
