On the Bias Distribution of Pseudo‐Linear Regression Algorithms for Recursive Identification

ABSTRACT This paper presents a detailed analysis of the asymptotic bias distribution of recursive identification schemes based on Pseudo‐Linear Regression. As shown in a previous article, the criterion asymptotically minimized is the variance of a non‐measurable signal (called th...

Sampled-Based Guided Quantum Walk: Non-variational quantum algorithm for combinatorial optimization

We introduce SamBa-GQW, a novel quantum algorithm for solving binary combinatorial optimization problems of arbitrary degree with no use of any classical optimizer. The algorithm is based on a continuous-time quantum walk on the solution space represented as a graph. The walker e...

Estimation of the relative effectiveness and waning of the monovalent third dose of COVID-19 vaccine against hospital admission in France: a novel self-controlled case series analysis.

We present a novel application of the SCCS method for estimating the effectiveness and waning of the third dose of COVID-19 monovalent vaccine in France. We used data on individuals hospitalised for COVID-19 between September 2021 and February 2022 from the Système National des D...

The insurance of climate-related physical risks: challenges and opportunities for actuaries

Abstract We examine the key challenges associated with insuring climate-related risks in the context of a changing climate. Adopting a balance-sheet perspective on insurance company management, we analyze the concept of insurability and how it may be reshaped by climate change. F...

Narratives and the psychological functions of narration in French lockdown diaries

The COVID-19 pandemic was an ‘extraordinary’ situation that raised many ethical and political questions about the role of care in society, as well as the exercise of democracy in the context of major restrictions on freedoms. During the first lockdown in France, many people share...

Development and investigation of a NiO/ZnO@PPy-modified glassy carbon electrode for electrochemical sensing of metronidazole in environmental samples: Experimental and DFT studies

Metronidazole (MTZ) is widely prescribed as an antimicrobial drug, and its extensive use in animal farming has led to its accumulation in the environment, posing significant risks to human health and the environment. In this study, nickel and zinc oxide (NiO/ZnO) composite materi...

War and peace in the early 21st century: An introduction

This introductory article critiques dominant, teleological social science narratives that position organised violence as a declining historical phenomenon. Instead, it asserts the structural centrality of warfare as a primary catalyst for institutional, political and societal tra...

Shipping noise may trigger valve closure responses in exploited scallop beds of the Gulf of St. Lawrence

Shipping noise is a pervasive form of underwater noise pollution, yet its effects on benthic invertebrates remain poorly integrated into spatial risk assessments. The Atlantic sea scallop (Placopecten magellanicus), a benthic bivalve supporting the world's largest wild pectinid f...

Simulation of the Rotational Molding Process of Polyethylene Using the Smoothed Particle Hydrodynamics Method

ABSTRACT This work presents the development of a numerical model based on the smoothed particle hydrodynamics (SPH) method to simulate the rotational molding process of powder thermoplastic polymers, used in the manufacture of liners for high‐pressure hydrogen tanks. Rotational m...

The algebraic structures of social organizations: the operad of cooperative games

The main goal of this paper is to settle a conceptual framework for cooperative game theory in which the notion of composition/aggregation of games is the defining structure. This is done via the mathematical theory of algebraic operads: we start by endowing the collection of all...

Evaluating Retrieval-Augmented Generation Strategies for Repository-Level Code Understanding

Retrieval-Augmented Generation (RAG) is increasingly employed to ground large language models in vast code repositories. However, performance degrades when resolving repository-level dependencies and multi-file code contexts. This study evaluates dense, sparse (BM25), and hybrid...

Alcohol and tobacco in cancer: A unified framework of interaction across carcinogenic pathways and cancer types

Background Alcohol and tobacco are among the leading preventable causes of cancer worldwide and frequently co-occur. While both are well-established independent carcinogens, their combined effects remain insufficiently characterized and inconsistently interpreted across cancer ty...
