Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

open access: yesHigh Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Comment on Photosystem II: light‐dependent oscillation of ligand composition at its active site: existence of O6 in S3‐state photosystem II revealed by omit maps

open access: yesActa Crystallographica Section D, EarlyView.
We reanalyzed our XFEL data, the results of which showed the insertion of O6 during the S2–S3 transition in water oxidation by photosystem II. These results contradict the interpretation proposed by Wang that there is no insertion of O6 during the S2–S3 transition.Photosystem II (PSII) catalyzes the light‐driven oxidation of water to molecular oxygen ...

Sino‐Mexican Encounters Before the ‘Diplomatic Opening’: Exhibition Diplomacy and Grassroots Friendship in the 1960s

open access: yesHistory, EarlyView.
Abstract During the 1960s, Mexico's Institutional Revolutionary Party (PRI) embraced Chinese overtures for a commercial opening as consistent with its anti‐imperialist posture, thereby foreshadowing the diplomatic opening to China in 1972. Yet this professed ideological pluralism was eclipsed by an underlying allegiance to the United States' anti ...

THE VIOLENCE OF FULL COST RECOVERY: Financing Water Infrastructure, and the History and Future of Perpetual Crisis in Mombasa

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Foregrounding the role of finance, this article examines the historical production and future trajectory of the urban water crisis in Mombasa. Drawing on archival research and contemporary fieldwork, it traces how principles of full cost recovery—institutionalized during the colonial period and later reworked through postcolonial ...

Landowners' Willingness to Participate in Temporary and Permanent Agri‐Environmental Schemes

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Within the EU and beyond, voluntary agri‐environmental and climate schemes (AES) are used to curtail externalities from agricultural production including nitrate leaching, biodiversity degradation and greenhouse gas emissions. This paper investigates and compares Danish landowners' preferences for temporary and permanent AES using a choice ...

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

open access: yesIntegrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Rapid Human Skin Barrier Disruption by Sodium Dodecyl Sulfate and Associated Molecular Mechanisms

open access: yesAllergy, EarlyView.
Short‐term exposure to SDS rapidly disrupts human skin barrier integrity within minutes, as detected by real‐time electrical impedance spectroscopy. SDS‐induced barrier dysfunction is driven by oxidative stress, leading to suppression of immune/barrier mediators and activation of stress, lipid remodeling, and epidermal differentiation pathways ...

Prevention of microglial activation and postoperative cognitive deficits by positive allosteric modulation of α5‐GABAA receptors

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Long‐lasting cognitive deficits after surgery in aged individuals, referred to as perioperative neurocognitive disorder (NCD), are a significant public health concern. Such postoperative cognitive deficits are dependent on the presence of microglia in the brain, which, when activated, trigger neuroinflammation.

Mechanistic Insights Into Recurrent Implantation Failure: The Lactate–H3K18la–SLC7A11 Axis Explored via Endometrial Organoid and Blastoid–Endometrial Cell Implantation Models

open access: yesCell Proliferation, EarlyView.
Clinical samples first revealed impaired lactate synthesis in RIF patients. Subsequently, using endometrial organoids and a blastoid‐endometrial cell implantation model, we demonstrated that lactate enhances endometrial receptivity via H3K18la‐mediated SLC7A11 activation.
