A BKW-Style Solver for the Restricted Syndrome Decoding Problem

The Restricted Syndrome Decoding Problem (RSDP) is a variant of the well-known syndrome decoding problem. It has been recently turned into a post-quantum signature scheme named CROSS by Baldi et al.. It is a scheme highlighted for being computationally friendly and providing a compact signature and public key size. This paper investigates an Oracle-based definition of the RSDP that has already pro

ENHANCING DIGITAL TWINS WITH DEEP REINFORCEMENT LEARNING : A USE CASE IN MAINTENANCE PRIORITIZATION

This paper introduces an innovative framework that enhances digital twins with deep reinforcement learning (DRL) to support maintenance in manufacturing systems. Utilizing a sophisticated artificial intelligence (AI) layer, this framework integrates real-time and historical production data from a physical manufacturing system to a digital twin, enabling dynamic simulation and analysis. Maintenance

Evaluating the potential benefits of float solar photovoltaics through the water footprint recovery period

In the context of higher demands on the development of clean energy technologies due to the issue of water shortage in China and the implementation of the 2060 carbon-neutral objective, floating photovoltaic (FPV) systems present novel opportunities for transforming the energy structure through land conservation and enhancement of power generation efficiency compared to conventional solar systems.

Physician's conceptions of the decision-making process when managing febrile infants ≤ 60 days old : a phenomenographic qualitative study

BACKGROUND: The management of febrile infants aged ≤ 60 days and adherence to guidelines vary greatly. Our objective was to describe the process of decision-making when managing febrile infants aged ≤ 60 days and to describe the factors that influenced this decision.METHODS: We conducted 6 focus group discussions with 19 clinically active physicians in the pediatric emergency departments of 2 univ

vNOTES retroperitoneal transient uterine artery occlusion : a new approach to control bleeding during a high-risk evacuation of products of conception

Objective: To describe a retroperitoneal transient occlusion of the uterine or internal iliac artery in conjunction with a high-risk evacuation of products of conception. The procedure was performed vaginally, minimally invasively, via vaginal natural orifice transluminal endoscopic surgery. Design: Description of the surgical technique using original video footage. This study was exempted from re

No title

This article presents readings of three French novels from the nineteenth century, namely Balzac's La Peau de chagrin, Huysmans' À rebours and Octave Mirbeau's Le Jardin des supplices. It examines issues of representation and meaning in relation to debt narratives and the use of bodies as a motif in relation to debt, and it argues that, in these novels, literary language and monetary representatio

Flight performance in night-flying sweat bees suffers at low light levels.

The sweat bee Megalopta (Hymenoptera: Halictidae), unlike most bees, flies in extremely dim light. And although nocturnal insects are often equipped with superposition eyes, which greatly enhance light capture, Megalopta performs visually guided flight with apposition eyes. We examined how light limits Megalopta's flight behavior by measuring flight times and corresponding light levels and compari

Personal factors in systemic sclerosis and their coverage by patient-reported outcome measures

Background. Systemic sclerosis (SSc) is an autoimmune disease where thickening of the skin can lead to reduced body function and limitations in activities. Severe forms can also affect and seriously damage inner organs. Patient-centred rehabilitation emphasises considerations of patients' background, experience and behavior which highlights the need to know if patient-reported outcome measures (PR

Computation of combined turbulent convective and impingement heat transfer

Impingement and forced convection are preferable methods for cooling gas turbine components. However, influences of various design parameters like crossflow and surface enlargements (like ribs) are not well understood. Thus there is a request for reliable and cost effective computational prediction methods, due to the experimental difficulties. such methods could be based on the numerical solution

Burgers rock creep around axisymmetric tunnels

The present paper deals with the time - dependent rock deformation during tunnelling, and more particularly, its association with the related phenomenon of creep in its viscoelastic form, as well as the numerical evaluation of it. Initially, a brief introduction of these two phenomena is provided. Then, the Burgers' idealized model of rheological rock mass behaviour is presented and analysed, alon

Hierarchical structure of fermion masses and mixings

We examine patterns where ratios of the fermion masses and the W-boson mass (xi= mi mw) are proportional to powers of a small parameter λ(xi=ciλPi). For a simple estimate of the uncertainty in the coefficients ci we determine the allowed values of Pi and the corresponding range of λ. Using this information we search for realistic patterns in a large class of anomaly-free SU(3)×SU(2)×U(1)×U(1) mode

Analyticity - An Unfinished Business in Possible World Semantics

The goal of this paper is to consider how the notion of analyticity can be dealt with in model-theoretical terms. The standard approach to possible-world semantics allows us to define logical truth and necessity, but analyticity is considerably more difficult to account for.
