Asymptotic giant branch stars are responsible for the production of most of the heavy isotopes beyond Sr observed in the solar system. Among them, isotopes shielded from the r-process contribution by their stable isobars are defined as s-only nuclei. For a long time the abundance of ^{204}Pb, the heaviest s-only isotope, has been a topic of debate because state-of-the-art stellar models appeared to systematically underestimate its solar abundance.

^{140}Ce(n,γ) is a key reaction for slow neutron-capture (s-process) nucleosynthesis due to being a bottleneck in the reaction flow. For this reason, it was measured with high accuracy (uncertainty ≈5%) at the n_TOF facility, with an unprecedented combination of a high purity sample and low neutron-sensitivity detectors. The measured Maxwellian averaged cross section is up to 40% higher than previously accepted values.

Inherited epidermolysis bullosa (IEB) is a group of genetically and clinically heterogeneous diseases characterized by the formation on the skin and mucous membranes blisters and erosion due to injury. Different forms of IEB can be accompanied by various extracutaneous complications, such as blisters and erosion on the cornea and mucous membranes, stenoses and strictures of the respiratory system, gastrointestinal tract, urinary system, muscle dystrophy, and malignant tumors. Therefore diagnosis and prescribing appropriate treatment and follow-up care is an important task for neonatologists and pediatric dermatologists.

Deficits in olfactory identification, despite normal odor perception, are found in some neuropsychiatric disorders, including schizophrenia. We examined if regional cerebral blood flow (rCBF) differed between schizophrenia patients and controls during odor identification, hypothesizing that these brain regions could be relevant to odor identification impairments. Eight schizophrenia and eight comparison subjects provided a baseline (picture identity matching) and activation (odor identification) SPECT scan, obtained using 99mTc-HMPAO in a low dose/high dose design.

This study demonstrates a clear relationship between noise induced tinnitus (NIT) and efferent neural auditory activity. The effect of contralateral white noise stimulation on click evoked otoacoustic emissions (CEOAEs) was studied in chronic tinnitus sufferers and controls, with and without a noise induced hearing loss (NIHL). For the non-tinnitus controls, increased contralateral white noise intensities resulted in decreased CEOAE amplitudes, irrespective of the hearing configuration.

It was previously demonstrated that noise induced tinnitus (NIT) patients have prolonged reaction times and event related potentials (ERPs) that are reduced in amplitude and prolonged in latency. This study considered whether these alterations occurred as a consequence of the competing auditory tinnitus sensation or as a result of a possible cognitive processing dysfunction in NIT patients. ERPs and reaction times (RTs) were recorded in response to a standard oddball auditory target detection paradigm, with and without simulated tinnitus.

Standards evoked potential averaging leads to a loss of information inherent in the moment to moment variability of the amplitude and latency of single evoked potentials. In order to extract this information, attempts were made to develop procedures which would allow recording of single visual evoked potentials in at least a selected group of subjects. In 11 out of 25 non-selected subjects, 43% to 86% of all stimuli (reversal checkerboard pattern elicited single visual evoked potentials (VEP) which were recognized as such by a group of independent observers.
