Low Frequency Dielectric Relaxation and Conductance of Solid Polymer Electrolytes with PEO and Blends of PEO and PMMA.

Solid polymer electrolytes are mixtures of polymer and inorganic salt. There are quite a number of studies dealing with the relationship between electric conductivity and structural relaxation in solid polymer electrolytes. We present a phenomenological approach based on fluctuation-dissipation processes.

Inscription of silicon waveguides using picosecond pulses.

Direct writing of single-mode waveguides into crystalline silicon using ps laser pulses is presented. The embedded structures were fabricated by moving the focal position along the beam axis with the help of a long distance microscope objective. In situ monitoring during inscription was performed to analyze the processing dynamics.

Characterization of HTT inclusion size, location, and timing in the zQ175 mouse model of Huntington's disease: an in vivo high-content imaging study.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder caused by a CAG trinucleotide repeat expansion in the huntingtin gene. Major pathological hallmarks of HD include inclusions of mutant huntingtin (mHTT) protein, loss of neurons predominantly in the caudate nucleus, and atrophy of multiple brain regions. However, the early sequence of histological events that manifest in region- and cell-specific manner has not been well characterized.

Effect of oxygen vacancies on the laser-induced damage resistance of Y0.26Hf0.74Ox thin films.

The influence of the oxygen sub-stoichiometry on the femtosecond laser-induced damage resistance of Y0.26Hf0.74Ox films was investigated in this work.

Dendritic structural degeneration is functionally linked to cellular hyperexcitability in a mouse model of Alzheimer's disease.

Dendritic structure critically determines the electrical properties of neurons and, thereby, defines the fundamental process of input-to-output conversion. The diversity of dendritic architectures enables neurons to fulfill their specialized circuit functions during cognitive processes. It is known that this dendritic integrity is impaired in patients with Alzheimer's disease and in relevant mouse models.
