Cohesion Policy and Institutional Quality Impact: Does Urban–Rural Classification Matter?

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract This study examines the impact of Cohesion Policy, and institutional quality, on regional economic performance across NUTS2 regions in 27 EU member states from 2007 to 2022. Average per capita Cohesion Policy payments are much higher in less developed regions, showing the policy focus on supporting lagging areas.

Markov Chains Approximations of jump-Diffusion Quantum Trajectories

open access: yes, 2008
"Quantum trajectories" are solutions of stochastic differential equations also called Belavkin or Stochastic Schr\"odinger Equations. They describe random phenomena in quantum measurement theory. Two types of such equations are usually considered, one is

Speciation of European bullheads (Cottus spp.): The next problem for taxonomy of northern freshwater fishes

open access: yesJournal of Fish Biology, EarlyView.
Abstract High morphological and ecological diversity displayed by European bullheads led Freyhof et al. (2005) to describe 15 nominal species. However, the basis for declaring these nominal species is contentious due to a lack of rigorous statistical analysis of morphological variations among populations, limitations in the inferences made from ...

Effects of warming on plant uptake of post‐fire nitrogen in an arctic heath tundra

open access: yesNew Phytologist, EarlyView.
Summary Postfire nitrogen (N) becomes increasingly important with the rising frequency of fires in arctic tundra, and climate warming is expected to accelerate plant recovery following fire. However, how plants differ in utilizing this postfire N and how their postfire N uptake responds to warming remains unknown.

Ozonized Hydrogel and Chlorhexidine Gel for Peri‐Implant Mucositis: A 24‐Month Randomized Controlled Trial

open access: yesOral Diseases, EarlyView.
ABSTRACT Objective This randomized controlled trial evaluated the 24‐month effectiveness of a nonsurgical intervention for peri‐implant mucositis, comparing a 15% ozonated sunflower oil hydrogel with a 1% chlorhexidine gel. Methods Thirty patients with 360 peri‐implant mucositis sites were treated in a split‐mouth design, receiving both therapies in ...

Association Between Oral Lichen Planus and Non‐Oral Cancers: A Multicentre Case–Control SIPMO Study

open access: yesOral Diseases, EarlyView.
ABSTRACT Objectives This multicentre case–control study aimed to investigate the potential association between oral lichen planus (OLP) and extraoral cancers. The secondary objective included the identification of risk factors for this association. Methods The study was conducted between January 2023 and June 2024 and included 21 Italian Oral Medicine ...

An XMM-Newton and Chandra investigation of the nuclear accretion in the Sombrero Galaxy (NGC4594)

open access: yes, 2003
We present an analysis of the XMM-Newton and Chandra ACIS-S observations of the LINER nucleus of the Sombrero galaxy and we discuss possible explanations for its very sub-Eddington luminosity by complementing the X-ray results with high angular ...
