We report on the observation of the solvation shell rearrangement after abstraction of the electron from aqueous I - in a laser pump/X-ray probe experiment by recording the X-ray absorption L 1 - and L 3 -edge spectra, 50 ps after laser excitation. The L 1 -edge spectra clearly identify the I 0 neutral species after excitation and suggest a substantial amount of back-transfer of charge from the s

The global burden of neurological disorders is substantial and increasing, especially in low-resource settings. The current increased global interest in brain health and its impact on population wellbeing and economic growth, highlighted in the World Health Organization’s new Intersectoral Global Action Plan on Epilepsy and other Neurological Disorders 2022–2031, presents an opportunity to rethink

With robots increasingly succeeding in exhibiting more human-like behaviours, humans may be more likely to ‘forgive’ their errors and continue to trust them as a result of ascribing higher, more human-like intelligence to them. If an integral aspect of successful HRI is to accurately communicate the competence of a robot, it can be argued that the technical success of the robot in exhibiting human

Type 2 Diabetes (T2D) is a disease of increasing importance and represents a growing burden on global healthcare and human health. In T2D, loss of effectiveness of insulin signaling in peripheral tissues cannot be compensated for by adequate insulin secretion, leading to hyperglycemia and resultant complications. In recent years, inflammation has been identified as a central component of T2D, both

Binary stars form from the same parent molecular cloud and thus have the same chemical composition. Forming planets take building material (solids) away from the surrounding protoplanetary disc. Assuming that the disc's accretion on to the star is the main process that clears the disc, the atmosphere of the star will show abundance reductions caused by the material accreted by the forming planet(s

User attitudes on privacy with respect to location data has been extensively studied. However, user attitudes of privacy in relation to proximity sensing is still lacking. We present the results from a survey conducted on users of a proximity sensing application we developed and diffused by handing out phones with the proximity sensing application pre-installed, with 31 respondents. The results co

The rich vacuum structure of multi-Higgs extensions of the Standard Model (SM) may have interesting cosmological implications for the electroweak phase transition (EWPT). As an important example of such class of models, we consider a particularly simple low-energy SM-like limit of a recently proposed Grand-Unified Trinification model with the scalar sector composed of two Higgs doublets and a comp

Most students of politics are familiar with Carl Schmitt’s definition of politics as a friend-enemy distinction. Yet, only few know of alternative conceptions of politics in interwar Germany that emphasize cooperation and legality over confrontation and decisionism. To unlock such views, this article examines the work of Hermann Heller, a social-democratic constitutional theorist, and takes a clos

This study provides new quantitative NO concentrations measurements in n-propanol + air and i-propanol + air flames together with a new combustion kinetic model. The heat flux method was employed to stabilize propyl alcohols flames and the initial gas conditions were set to 323 K, 1 atm, and ϕ=0.7-1.4. Saturated laser-induced fluorescence was employed to measure NO concentration in the post-combus

The biosynthesis of selenoproteins was studied in relation to milk formation and mammary cell biology by incubating the bovine mammary cell line MAC-T with (75Se)selenite. Intracellular proteins and proteins secreted into the cell culture medium were separated by 2D electrophoresis, the selenoproteins were detected by autoradiography, and the proteins were identified by MALDI-TOF. Approximately 35

Mid-infrared polarization spectroscopy (IRPS) and laser-induced fluorescence (IRLIF) have been applied for detection of methane and ethane in atmospheric pressure cold flows and flames. Lines belonging to the asymmetric C-H stretching vibration bands v₃ and v₇ for methane and ethane, respectively, were probed with a tunable infrared laser beam at about 3.4 μm, which was obtai
