Urban Cycling as an Indicator of Socio-Economic Innovation and Sustainable Transport
Quaestiones Geographicae, 2018 Environmental pollution in cities is an increasingly popular issue tackled in research. One of the elements with a significant impact on the state of urban ecosystems is transport with its pressure on individual components of the environment. Sustainable

American Journal of Industrial Medicine, EarlyView.ABSTRACT Introduction This study examined initial stay times (IST), defined as the duration of uninterrupted work before core temperature approaches recommended safety limits (38.0°C, ~1.0°C above baseline), and the efficacy of work‐rest cycles during repeated heavy work across consecutive workdays in young and older males.

Direct Access to Chiral Piperidines by Enantioselective HAT‐Initiated C(sp3)─H Oxidation
Angewandte Chemie, EarlyView.The direct desymmetrization of piperidines is achieved through manganese‐catalyzed enantioselective α‐C(sp3)─H oxidation with hydrogen peroxide, affording versatile chiral N,O‐acetals in good yields and with high enantio‐ and diastereoselectivity. These intermediates provide access to diverse functionalized piperidines with retention of chirality ...

Coexisting Microvehicles and Pedestrians: A Novel Modeling Approach
Urban ScienceMicrovehicles, such as e-scooters and bicycles, are increasingly used in urban transport systems. Existing models were primarily developed either for pedestrians-only or motor vehicles-only and cannot fully capture the dynamics of microvehicles ...

Cerebellar Abnormalities in the Neuroimaging Spectrum of CLTC‐Related Disorder
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Pathogenic variants in CLTC, which encodes the clathrin heavy chain involved in vesicle‐mediated trafficking in neurons, cause a rare neurodevelopmental disorder associated with variable severity of global developmental delay and intellectual disability and structural brain abnormalities. Although corpus callosum and white matter anomalies are

Angewandte Chemie, EarlyView.A metal‐free photocatalytic platform converts nitrones into 4‐isoxazolines and oxa–aza–bicycloheptanes through divergent [3+2π/σ] cycloadditions. Assembly‐controlled kinetic electron transfer gating dictates substrate activation, enabling selective reactivity beyond thermodynamic expectations.

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Introduction Traditional management of traumatic skull base dural injury has often favored observation and conservative therapy, despite the risk of delayed intracranial complications. This paradigm originated when operative intervention required craniotomy and carried significant morbidity.
