estimates, thereby neglecting the inherent uncertainty within demand
projections. Moreover, MoD demand l... | http://arxiv.org/abs/2310.09847v2 |
A setup that simulates ground states of spin graphs would allow one to solve
computationally hard optimisation problems efficiently. Current optical setups
to this goal have difficulties decoupling the amplitude and phase degrees of
freedom of each effective spin; risking to yield the mapping invalid, a problem
known a... | http://arxiv.org/abs/2306.05743v3 |
Quality of Service (QoS) prediction is an essential task in recommendation
systems, where accurately predicting unknown QoS values can improve user
satisfaction. However, existing QoS prediction techniques may perform poorly in
the presence of noise data, such as fake location information or virtual
gateways. In this p... | http://arxiv.org/abs/2308.02580v2 |
Privacy is one of the key challenges to the adoption and implementation of
online proctoring systems in higher education. To better understand this
challenge, we adopt privacy as contextual integrity theory to conduct a scoping
review of 17 papers. The results show different types of students' personal and
sensitive in... | http://arxiv.org/abs/2310.18792v1 |
The blowout preventer (BOP) system is one of the most important well safety
barriers during the drilling phase because it can prevent the development of
blowout events. This paper investigates BOP system's main failures using an
LSA-based methodology. A total of 1312 failure records from companies worldwide
were collec... | http://arxiv.org/abs/2301.00844v1 |
We report progress on the study of the inclusive semi-hard hadroproduction of
a Higgs+jet system at LHC and FCC collision energies. We describe a prototype
matching procedure aimed at combining NLO fixed-order computations via POWHEG,
with the NLL resummation of energy logarithms from JETHAD. We present
preliminary ana... | http://arxiv.org/abs/2310.16967v1 |
Real-world robotic tasks stretch over extended horizons and encompass
multiple stages. Learning long-horizon manipulation tasks, however, is a
long-standing challenge, and demands decomposing the overarching task into
several manageable subtasks to facilitate policy learning and generalization to
unseen tasks. Prior ta... | http://arxiv.org/abs/2310.08581v1 |
Clinical data in hospitals are increasingly accessible for research through
clinical data warehouses. However these documents are unstructured and it is
therefore necessary to extract information from medical reports to conduct
clinical studies. Transfer learning with BERT-like models such as CamemBERT has
allowed majo... | http://arxiv.org/abs/2306.15550v3 |
As recently shown, the a-anomaly of the UV fixed point of 4d quantum field
theories, can be constrained by studying scattering amplitudes. The basic idea
is to couple the QFT to a dilaton and impose unitarity of the scattering
amplitudes of physical particles and probe dilatons. In this work we find new
lower bounds on... | http://arxiv.org/abs/2307.02305v2 |
The concept of Artificial Intelligence has gained a lot of attention over the
last decade. In particular, AI-based tools have been employed in several
scenarios and are, by now, pervading our everyday life. Nonetheless, most of
these systems lack many capabilities that we would naturally consider to be
included in a no... | http://arxiv.org/abs/2303.04283v1 |
The Meshless Lattice Boltzmann Method (MLBM) is a numerical tool that
relieves the standard Lattice Boltzmann Method (LBM) from regular lattices and,
at the same time, decouples space and velocity discretizations. In this study,
we investigate the numerical convergence of MLBM in two benchmark tests: the
Taylor-Green v... | http://arxiv.org/abs/2306.01525v2 |
The development of thermal boundary layers and plume near a
section-triangular roof under different isothermal heating conditions have been
the focus of numerous numerical studies. However, flow transition in this type
of flow has never been observed experimentally. Here, phase-shifting
interferometry and thermistor me... | http://arxiv.org/abs/2307.09250v2 |
Breast cancer early detection is crucial for improving patient outcomes. The
Institut Catal\`a de la Salut (ICS) has launched the DigiPatICS project to
develop and implement artificial intelligence algorithms to assist with the
diagnosis of cancer. In this paper, we propose a new approach for facing the
color normaliza... | http://arxiv.org/abs/2305.07404v1 |
A theoretical and computational study analysing the initiation of
yield-stress fluids percolation in porous media is presented. Yield-stress
fluid flows through porous media are complicated due to the non-linear
rheological behaviour of this type of fluids, rendering the conventional Darcy
type approach invalid. A crit... | http://arxiv.org/abs/2308.08913v3 |
