Absorption of hydrogen in thin films is important for a wide range of applications, including hydrogen membranes, sensor technology, and programmable resistors for artificial neural networks. In this study, we demonstrate that analysing the kinetics of the absorption process with a combination of direct and indirect methods provides a much clearer and more detailed picture of the individual processes involved than the usual investigations in thermodynamic equilibrium do.

Mineral Cup is an annual global volunteer-run competition to determine the most popular mineral, decided by public voting and played out mainly on social media. Over nine years of Mineral Cup, nine distinct minerals or mineral groups have been crowned champion, in chronological order: olivine, garnet, ice, magnetite, quetzalcoatlite, fluorite, zircon, rhodochrosite and kyanite. [...]

During late gestation and early postnatal development a combination of intrinsic and extrinsic factors drive the maturation of the human cortex. This process is regionally heterogeneous, with cortical areas developing at different paces and trajectories. [...]

It is assumed that amino acid PET positivity of gliomas corresponds to tracer uptake by tumor cells via the amino acid transporter heterodimer CD98, consisting of a light (LAT1) and heavy subunit (CD98hc), but correlative studies of human tumor tissue samples and PET imaging are largely lacking. Methods: We evaluated a series of 31 patients with diffuse glioma (18 IDH-mutant, 13 IDH-wild type), of whom preoperative amino acid PET images and corresponding tumor tissue samples were available. [...]

Cross-frequency coupling (CFC) has been proposed to facilitate neural information transfer across spatial and temporal scales. Phase-amplitude coupling (PAC), a type of CFC in which the amplitude of a faster brain oscillation is coupled to the phase of a slower brain oscillation, is implicated in various higher-order cognitive functions and was shown to be pathologically altered in neurological and psychiatric disease. [...]

Isolated/idiopathic rapid-eye-movement (REM)-Sleep Behavior Disorder (iRBD) is characterized by dream enactment behaviors associated with loss of REM atonia. iRBD is in most cases a prodromal synucleinopathy, and emerging evidence suggests associations between RBD and other neurological and psychiatric conditions [...]

Beyond immediate neuronal damage, functional and structural connectivity is altered brain-wide with implications for functional deficits and recovery in stroke. It remains unclear, however, if the level of axonal damage, as well as compensatory plasticity, i.e., axonal sprouting and remyelination, depend on the lesion size and topology [...]
