Two stacks of thin Zr foils were irradiated with 30 and 50 MeV deuterons, respectively, using the Lawrence Berkeley National Laboratory 88-Inch Cyclotron, and 19 excitation functions for natZr(d,x) reactions were measured over a beam energy range of 6.3–47.64 MeV, where the independent cross sections for natZr(d,x)88Nb and natZr(d,x)86m,gY were measured for the first time. The well-characterized natFe(d,x)56Co, natNi(d,x)56Co, natNi(d,x)58Co, natNi(d,x)61Cu, natTi(d,x)46Sc and natTi(d,x)48V monitor reactions were used to determine the deuteron beam current throughout the stacks.

Tropospheric ozone pollution in South Asia is mainly blamed on anthropogenic emissions. However,based on ERA5 reanalysis data, this study highlights the contribution of stratospheric ozone intrusions intothe Upper Troposphere and Lower Stratosphere (UTLS) associated with Sudden Stratospheric Warming (SSW)events in enhancing upper tropospheric ozone over the South Asian region.

Introduction: Age-related declines in cognitive and motor functions show highly variable trajectories. To better understand the underlying mechanisms, we investigated multivariate associative effects between modifiable vascular risk factors, biological brain aging, cognitive, and motor performance in 40,579 individuals from the population-based UK Biobank and Hamburg City Health Study.Methods: We employed partial least squares correlation analysis (PLS) to model associations between multi-domain cognitive and motor test scores and three distinct MRI-derived markers of biological brain aging: relative brain age (from morphometric brain imaging), white matter hyperintensity load, and peak width of skeletonized mean diffusivity. [...]

Background: Friedreich ataxia is a debilitating multisystem neurodegenerative disorder. Depression is more prevalent in individuals with Friedreich ataxia (14%-36%) than in the general European population (8.5%). [...]

Motor performance (MP) is essential for maintaining functional independence, particularly in later life. However, the relationship between MP and sleep quality, depressive symptoms, and their underlying brain substrates remains obscure. [...]

Photovoltaic (PV) technologies are central to renewable energy generation, yet their intermittent output limits efficient utilization and grid integration. Coupling PV with short- and long-term energy storage at the earliest stage of electricity generation is an attractive but challenging strategy for stabilizing PV output. [...]

Rapid eye movement (REM) sleep behaviour disorder (RBD), particularly its idiopathic/isolated form (iRBD), is a prodromal marker for α-synucleinopathies, including Parkinson's disease, dementia with Lewy bodies and multiple system atrophy. Machine learning (ML) offers opportunities to improve diagnosis and risk stratification in this high-risk group. [...]

BackgroundPrevious research has suggested an association between insomnia disorder (ID) and alterations in emotion processing. Therefore, it is crucial to investigate neurobiological changes in emotion processing in patients with ID before and after Cognitive Behavioral Therapy for Insomnia (CBT-I) and to compare them with healthy controls (HC) with task-based functional magnetic resonance imaging (fMRI).Methods20 patients with ID and 20 HC were included in this study to view five different blocks of pictures with varying emotional arousal, valence, and content (sleep-relatedness) in the fMRI scanner.ResultsA significant Group × Session interaction was identified in the amygdala for both the sleep-related negative contrast (F(1,38) = 4.19, p = .048) and the neutral moderate contrast (F(1,38) = 5.39, p = .026).
