Anisotropic variable exponent Sobolev spaces and applications to elliptic equations with critical growth

Abstract We establish critical embeddings for anisotropic Sobolev spaces with variable exponents, resolving, under log-Hölder continuity supplemented by finite Sobolev regularity and a quantitative integrability-gap condition, an open problem raised by Fan. We derive a Poincaré-t...

Phytochemical Profiling and Biological Activities of Moroccan Rhus pentaphylla

Rhus pentaphylla Desf., a medicinal plant traditionally used in North Africa, remains insufficiently investigated with respect to its glycoconjugate composition and biological properties. This study investigated the influence of extraction solvent on the LC–ESI–MS/MS profiles and...

Unpacking the Role of Financial Incentives in the Motivation and Individual Performance of Nurses in LMICs: A Scoping Review Protocol

ABSTRACT Background Health systems in low‐ and middle‐income countries (LMICs) continue to face persistent challenges related to health worker performance and quality of care, exacerbated by a global shortage of nurses. Financial incentive strategies (FIS), which include performa...

Phenolic Profiling and OECD-Guided Acute and Subacute Oral Toxicity Assessment of Cannabis sativa L. Seed Hydroethanolic Extract

Cannabis sativa L. seeds have been traditionally used in Moroccan folk medicine and are increasingly recognized as a valuable source of nutrients and bioactive phytochemicals with promising therapeutic properties. Despite their widespread traditional and nutritional use, scientif...

Pre-registration amendment v3 (L1C calibration result and exploratory declarations): When snow looks like water: wet-snow false floods in winter Sentinel-1 flood mapping of the Tensift basin (High Atlas, Morocco)

Amendment v3 to the pre-registration (v1 10.5281/zenodo.23130459; v2 10.5281/zenodo.23144531). L1C/L2A calibration gate on the held-out pilot winter: κ 0.800 [0.698–0.881], 321 snow pairs, 93.9% L1C visibility (≥ 1,500 m), so the 9-winter analysis is primary. It includes a declar...

Surrogate‐Assisted Multi‐Objective Optimization of an Axial‐Flow Ventricular Assist Device Rotor Using CFD , Hybrid Surrogates, Sobol Analysis, and MOPSO

ABSTRACT Background This study presents a surrogate‐assisted workflow for multi‐objective optimization of an axial‐flow ventricular assist device (VAD) rotor using 4809 steady‐state CFD simulations spanning six geometric variables. Methods Repeated learning‐curve analysis and bla...

Pre-registration: When snow looks like water: wet-snow false floods in winter Sentinel-1 flood mapping of the Tensift basin (High Atlas, Morocco)

This record pre-registers a study of wet-snow false positives in winter Sentinel-1 change-detection flood mapping in the Tensift basin (High Atlas, Morocco). The pilot winter 2019–20 was used to build and test the pipeline and is excluded from all confirmatory tests. The confirma...

A Semantic-Gated Structural Diversity Penalty to Mitigate Orchestrated Recommendation Attacks in the SIoT

The Social Internet of Things (SIoT) trust algorithms typically assume peer recommendations are independent, this leaves them vulnerable to coordinated Fake Relationship Attacks (FRA). Adversaries exploit this vulnerability by creating dense malicious cliques to manipulate trust...

Behavioral and economic drivers of renewable energy adoption by MSMEs in the MENA region

Abstract Micro, small, and medium enterprises (MSMEs) dominate the MENA private sector, yet renewable-energy technology (RET) adoption remains limited. Using nationally representative TCEES 2023–2024 data from Egypt, Jordan, and Morocco, this study models RET engagement as sequen...

From gravity models to supply chain resilience: a bibliometric analysis of free trade agreement research

Purpose This study examines the evolution and intellectual structure of research at the intersection of free trade agreements (FTAs), gravity models, and supply chain resilience. It aims to determine how resilience- and logistics-oriented perspectives have developed alongside tra...

Ethnopharmacological insights into type 2 diabetes management by traditional Moroccan herbal teas: HPLC-MS characterization of phenolic compounds and their related antioxidant and enzyme inhibitory activities

Abstract Background Traditional Moroccan herbal teas are widely consumed and have been traditionally used for managing chronic metabolic disorders, particularly type 2 diabetes mellitus (T2DM). Although these preparations have a long history of ethnomedicinal use, their phenolic...

From electrolyzer tradeoffs to certified green hydrogen deployment through hydrogen valleys

Green hydrogen projects are not shaped by electrolyzer performance alone. Even a technically efficient system can be difficult to deploy if renewable supply, local infrastructure, or certification rules are poorly matched to it. This review considers these issues together. AEL, P...

Sentiment as a Brake, Not a Signal: A Profit-at-Risk and Placebo Attribution of Affective Features in Equity Trading Systems

Trading systems increasingly use the affective content of financial text to size positions, assuming that sentiment carries information a price-based model lacks. We ask whether that assumption survives a falsification test. Using more than three million social-media and news mes...

How fast can PPRV spread? Analyzing the results of an experimental PPRV infection of goats equipped with Ultra-Wideband sensors

Peste des Petits Ruminants (PPR) is a highly contagious disease affecting goats and sheep. The speed and extent of its spread depend on contact patterns and the virus’s intrinsic characteristics. To estimate its propagation speed and the role of inter-individual contacts, we cond...

A 3D meshless electromechanical model incorporating electrode inertia for accurate prediction of resonance characteristics in disk-type MEMS resonators

In this study, wave propagation in disk-type piezoelectric resonators is investigated by extending the polynomial modeling approach to incorporate electrode inertia. For sufficiently thin metallic electrodes, their elastic stiffness is neglected and only their mass contribution i...

Decentralized homologous recombination deficiency (HRD) testing in advanced high-grade serous ovarian carcinoma: real-world implementation and molecular profiling from Morocco
