Semiconducting Covalent Organic Frameworks Based on Spin‐Delocalized Trioxotriangulene Neutral Radicals

open access: yesAngewandte Chemie International Edition, EarlyView.
Imine‐linked 2D covalent organic frameworks incorporating delocalized trioxotriangulene (TOT) neutral radicals were synthesized through complementary routes. Direct incorporation of an amine‐functionalized TOT radical yields a highly crystalline, porous framework (TOT‐COF‐H) with intrinsic semiconducting behavior (σRT = 1.2 × 10−4 S cm−1) and a narrow ...

Low‐Intensity Precipitation Dominates Peninsular Spain (1961–2022)

open access: yesInternational Journal of Climatology, EarlyView.
Spatial analysis across Spain shows a shift in precipitation regimes (1961–2022) toward more frequent low‐intensity precipitation and reduced high‐intensity events, with localised increases in heavy precipitation along some coastal areas. This redistribution—captured through changes in precipitation frequency (RF) and volumetric contribution (RC ...

A New Hydroclimatic Signature: Negative NAO Dominance Under Weak La Niña Conditions During the 2025–2026 Northwest Africa Floods

open access: yesInternational Journal of Climatology, EarlyView.
Conceptual hydroclimatic pathway linking the concurrent negative North Atlantic Oscillation (NAO) phase and weak La Niña conditions to extreme February rainfall and flash flooding in Northwest Africa. ABSTRACT The winter of 2025–2026 in Morocco exhibited a rapid hydroclimatic transition from prolonged drought to widespread flooding, representing an ...

Impact of COVID‐19 and Vaccination on Lower Urinary Tract Symptoms: Insights From a Prospective Cohort Study

open access: yesNeurourology and Urodynamics, EarlyView.
ABSTRACT Aims To evaluate the prevalence, clinical course, and risk factors of lower urinary tract symptoms (LUTS) in patients hospitalized with COVID‐19, and to assess associations with comorbidities, disease severity, and vaccination status. Methods We conducted a prospective cohort study of adult patients hospitalized with confirmed COVID‐19, who ...

Lagrangian analysis of two flavours of Central European heatwaves: Formation under omega blocking versus initiation by subtropical ridges

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate whether Central European heatwaves (HWs) forming under omega blocking differ from those enabled by subtropical ridges, in terms of both air‐mass origin and processes warming air parcels along their way. Using ERA5‐based backward trajectories and a Lagrangian temperature anomaly decomposition, we identify significant differences in the ...

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

open access: yesJournal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

‘Enthusiasts’ and ‘Fanatics’: The Decembrists as a Case Study in French Influence on Russian Culture, Emotions and Thought

open access: yesHistory, EarlyView.
Abstract Participants in Russia's 1825 Decembrist uprising against the Tsarist regime were, quite literally, a case study in French cultural influence upon Russia. This is particularly true as it relates to Russia's emotional cultures. Although this has not, traditionally, been the primary focus of historical analysis of this event (in Soviet or ...

The bread of Toledo: Prices and political economy, 1535–1800

open access: yesThe Economic History Review, EarlyView.
Abstract We study the market for common white bread in the city of Toledo through a new 266‐year‐long series of bread prices, obtained from the cash purchases and wholesale bread‐for‐wheat contracts of large institutions. Our data are strongly consistent with fragmentary evidence on retail price regulation, as well as with shorter series from other ...

Dependent Articulation in the Global Pesticide Complex: Argentina's Agrochemical Industry After the Generics Market Revolution

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT Since the late 1990s, the pesticide industry has undergone a ‘generics revolution’ as the centre of production, and trade has shifted to the global South. China and India have become major producers, capturing Latin American markets from Northern multinationals. As a major pesticide user and a key node in global supply chains, Argentina offers
