XUV-beamline for photoelectron imaging spectroscopy with shaped pulses.

We introduce an extreme ultraviolet (XUV)-beamline designed for the time-resolved investigation and coherent control of attosecond (as) electron dynamics in atoms and molecules by polarization-shaped as-laser pulses. Shaped as-pulses are generated through high-harmonic generation (HHG) of tailored white-light supercontinua (WLS) in noble gases. The interaction of shaped as-pulses with the sample is studied using velocity map imaging (VMI) techniques to achieve the differential detection of photoelectron wave packets.

Treating depression at home with transcranial direct current stimulation: a feasibility study.

Introduction: Treating major depressive disorder (MDD) with transcranial direct current stimulation (tDCS) devices at home has various logistic advantages compared to tDCS treatment in the clinic. However, preliminary (controlled) studies showed side effects such as skin lesions and difficulties in the implementation of home-based tDCS. Thus, more data are needed regarding the feasibility and possible disadvantages of home-based tDCS.

Who are the speech and language therapists who work with primary progressive aphasia in Brazil? An exploratory cross-sectional survey study.

Unlabelled: Primary Progressive Aphasia (PPA) is a progressive language disorder associated with frontotemporal impairment and mainly affects the left hemisphere of the brain. In general, this condition compromises abilities related to comprehension and expression of language. The diagnosis of PPA depends on in-depth knowledge regarding functions of language, neurology, and neuropsychology.

Raster-scanning optoacoustic mesoscopy biomarkers for atopic dermatitis skin lesions.

Atopic dermatitis (AD) is the most common chronic inflammatory skin disease worldwide. Its severity is assessed using scores that rely on visual observation of the affected body surface area, the morphology of the lesions and subjective symptoms, like pruritus or insomnia. Ideally, such scores should be complemented by objective and accurate measurements of disease severity to standardize disease scoring in routine care and clinical trials.

Synthesis and hydrogenation of polycyclic aromatic hydrocarbon-substituted diborenes uncatalysed hydrogenative B-C bond cleavage.

The classical route to the PMe-stabilised polycyclic aromatic hydrocarbon (PAH)-substituted diborenes BAr(PMe) (Ar = 9-phenanthryl 7-Phen; Ar = 1-pyrenyl 7-Pyr) the corresponding 1,2-diaryl-1,2-dimethoxydiborane(4) precursors, BAr(OMe), is marred by the systematic decomposition of the latter to BAr(OMe) during reaction workup. Calculations suggest this results from the absence of a second -substituent on the boron-bound aryl rings, which enables their free rotation and exposes the B-B bond to nucleophilic attack. 7-Phen and 7-Pyr are obtained by the reduction of the corresponding 1,2-diaryl-1,2-dichlorodiborane precursors, BArCl(PMe), obtained from the SMe adducts, which are synthesised by direct NMe-Cl exchange at BAr(NMe) with (MeS)BCl.
