Electroclinical and genetic profiling of Tunisian families with malformations of cortical development: report of novel DENND5A mutation, functional DYNC1H/DCX variants and structural correlates

Malformations of cortical development (MCD) are neurodevelopmental disorders arising from disrupted neuronal proliferation and migration during embryogenesis and represent a major cause of epilepsy and developmental impairment. Although numerous genes have been implicated, varian...

Rank‐Maximal Robust Augmented Observer for Simultaneous Actuator and Sensor Fault Reconstruction in Fractional‐Order Descriptor One‐Sided Lipschitz Systems

ABSTRACT This paper develops a rank‐maximal robust augmented observer that simultaneously reconstructs the state, the actuator faults and the sensor faults of fractional‐order descriptor (singular) systems whose nonlinearity satisfies the one‐sided Lipschitz (OSL) and quadratic i...

Boron Monofluoride Complexes Bearing π‐Expanded Coumarin Subunits: Facile Synthesis, Crystal Structure, and Solid‐State Enhanced Emission

Boron-containing compounds have received special interest over the last few years owing to their favorable photophysical characteristics, stimulating their use as fluorescent sensors, in bioimaging and mechanofluorochromic materials. However, their synthesis is often time-consumi...

Geopolitical conflict, global uncertainty and equity market resilience in the MENA region: evidence from a quantile machine-learning framework

Purpose This study aims to examines how global uncertainty and domestic geopolitical conflict affect equity market resilience in six Middle East and North Africa (MENA) economies across stress, normal and expansion regimes. Design/methodology/approach Using monthly MSCI country-i...

Wear mechanisms and damage evolution of superelastic NiTi orthodontic archwires under coupled bending-sliding loading in simulated oral conditions

Nickel–titanium (NiTi) archwires are widely used in orthodontic applications due to their superelastic response and ability to deliver nearly constant forces. During clinical service, these components are subjected to repeated sliding, bending, and moderate temperature variations...

Synthesis, design and integrated in vitro/in silico assessment of novel cyano-amide derivatives

A novel and an efficient synthesis of a series of cyano-amide derivatives 3a-h was achieved via solvent-free reaction of benzylcyanide derivatives 1 with isocyanate derivatives 2 at room temperature. The produced components were structurally characterized by NMR spectroscopy mult...

Impacts of the digital economy on industrial employment and CO2 emissions: a comparison between developed and developing countries

This article assesses the impact of the digital economy on industry and the environment by comparing 15 countries (7 developed and 8 developing) over the period 2000–2021. Using the System Generalized Method of Moments (SYS-GMM), the analysis reveals contrasting results between c...

Digital Transformation, Carbon Disclosure and Firm Performance: The Moderating Role of Green Innovation in European Listed Firms

ABSTRACT In the context of accelerating digital and sustainability transitions, firms increasingly face the strategic challenge of simultaneously enhancing technological capabilities and environmental transparency. This study examines the associations of digital transformation an...

Digital literacy shapes AI chatbot adoption, barriers, and performance outcomes in football coaches: a multi-method analytical study

Abstract The adoption of AI chatbots among football coaches is primarily determined by their digital literacy. An international cross-sectional online survey of 213 professional coaches measured adoption and digital literacy using a psychometrically evaluated 31-item index. Data...

A novel hyperchaotic system derived from asymmetric bidirectional coupling of two Lorenz oscillators: Synchronization analysis and cryptographic applications

This paper investigates a six-dimensional coupled Lorenz system obtained through bidirectional asymmetric diffusive coupling of two identical Lorenz oscillators. The proposed model is analyzed from both dynamical and synchronization perspectives. Dissipativity conditions, equilib...
