Why are some research studies easy to reproduce while others are difficult?
Casting doubt on the accuracy of scientific work is not fruitful, especially
when an individual researcher cannot reproduce the claims made in the paper.
There could be many subjective reasons behind the inability to reproduce a
scientific pape... | http://arxiv.org/abs/2308.12580v1 |
We introduce the Condorcet attack, a new threat to fair transaction ordering.
Specifically, the attack undermines batch-order-fairness, the strongest notion
of transaction fair ordering proposed to date. The batch-order-fairness
guarantees that a transaction tx is ordered before tx' if a majority of nodes
in the system... | http://arxiv.org/abs/2306.15743v1 |
By means of the contour integration method, we evaluate, in closed form, a
class of definite integrals involving hyperbolic tangent function. | http://arxiv.org/abs/2310.19847v1 |
Transparency and data portability are two core principles of modern privacy
legislations such as the GDPR. From the regulatory perspective, providing
individuals (data subjects) with access to their data is a main building block
for implementing these. Different from other privacy principles and respective
regulatory p... | http://arxiv.org/abs/2305.03471v1 |
We propose JEIT, a joint end-to-end (E2E) model and internal language model
(ILM) training method to inject large-scale unpaired text into ILM during E2E
training which improves rare-word speech recognition. With JEIT, the E2E model
computes an E2E loss on audio-transcript pairs while its ILM estimates a
cross-entropy ... | http://arxiv.org/abs/2302.08583v1 |
We present a Markl-style definition of operads colored by a small category.
In the presence of a unit these are equivalent to substitudes of Day and
Street. We show that operads colored by a category are internal algebras of a
certain categorical operad of functors. We describe a groupoid-colored
quadratic binary opera... | http://arxiv.org/abs/2304.02446v2 |
The sparse matrix/vector product (SpMV) is a fundamental operation in
scientific computing. Having access to an efficient SpMV implementation is
therefore critical, if not mandatory, to solve challenging numerical problems.
The ARM-based AFX64 CPU is a modern hardware component that equips one of the
fastest supercompu... | http://arxiv.org/abs/2307.14774v1 |
We study the periodic homogenization of a reaction-diffusion problem with
large nonlinear drift and Robin boundary condition posed in an unbounded
perforated domain. The nonlinear problem is associated with the hydrodynamic
limit of a totally asymmetric simple exclusion process (TASEP) governing a
population of interac... | http://arxiv.org/abs/2307.04567v1 |
The Queen's Domination problem, studied for over 160 years, poses the
following question: What is the least number of queens that can be arranged on
a $m \times n$ chessboard so that they either attack or occupy every cell?
We propose a novel relaxation of the Queen's Domination problem and show that
it is exactly so... | http://arxiv.org/abs/2304.06620v1 |
The rapid adoption of smart grids demands robust security and efficiency
measures due to their critical role in delivering electricity and their
potential for customer-oriented benefits. This paper presents an innovative
framework, named RETINA, which provides a resilient and secure energy trading
mechanism within smar... | http://arxiv.org/abs/2306.08074v1 |
Starting from the product of a $3$-torus and a compact K\"ahler
(respectively, hyperK\"ahler) manifold we construct via mapping tori
generalized K\"ahler manifolds of split (respectively, non-split) type. In this
way we obtain new non-K\"ahler examples and we recover the known examples of
generalized K\"ahler solvmanif... | http://arxiv.org/abs/2305.11075v3 |
Mobile applications are required to give privacy notices to the users when
they collect or share personal information. Creating consistent and concise
privacy notices can be a challenging task for developers. Previous work has
attempted to help developers create privacy notices through a questionnaire or
predefined tem... | http://arxiv.org/abs/2305.06509v1 |
All data on the Internet are transferred by network traffic, thus accurately
modeling network traffic can help improve network services quality and protect
data privacy. Pretrained models for network traffic can utilize large-scale raw
data to learn the essential characteristics of network traffic, and generate
disting... | http://arxiv.org/abs/2304.09513v2 |
The work presented in this paper was carried out in the context of the
project Girls and boys: one day at university promoted by the City of Turin
together with the University of Turin. We were responsible for two educational
