The spatio-temporal characteristics of grey matter (GM) impairment in multiple sclerosis (MS) are poorly understood. We used a new surface-based diffusion MRI processing tool to investigate regional modifications of microstructure, and we quantified volume loss in GM in a cohort of patients with MS classified into three groups according to disease duration.

11 p, 3.0 MB Observation of slow light in glide-symmetric photonic-crystal waveguides / Patil, Chirag Murendranath (Technical University of Denmark.

Department of Physics and Astronomy) ; García Fernández, Pedro David (Institut Català de Nanociència i Nanotecnologia) ; Stobbe, Søren (Technical University of Denmark. Department of Photonics Engineering)
We report optical transmission measurements on suspended silicon photonic-crystal waveguides, where one side of the photonic lattice is shifted by half a period along the waveguide axis. The combination of this glide symmetry and slow light leads to a strongly enhanced chiral light-matter interaction but the interplay between slow light and backscattering has not been investigated experimentally in such waveguides.

11 p, 628.4 KB Animacions en stop-motion : una oportunitat per aprofundir en el model cineticomolecular de la matèria / Barbero Camps, Elisabet (INS Santa Coloma de Farners(Santa Coloma de Farners))
El model cineticomolecular és primordial per a la interpretació de diversos fenòmens de la matèria i constitueix una base de l'aprenentatge de la química. Però les partícules no són observables i alguns aspectes del model són complexos d'integrar: per exemple, el moviment de les partícules i els seus canvis amb la temperatura tenen molta importància en el model, però difícilment es descriuen en representacions gràfiques. [...]
Kinetic-molecular theory is the key for interpretation of diverse matter phenomena, and it is the basis of chemical learning. However, particles cannot be seen, and some aspects of the model are difficult to acquire: for instance, particle movement related to temperature is very important in interpretations, but it is hardly represented in student's drawings and explanations. [...]

Psychotic major depression (PMD) is hypothesized to be a distinct clinical entity from nonpsychotic major depression (NPMD). However, neurobiological evidence supporting this notion is scarce. The aim of this study is to identify gray matter volume (GMV) differences between PMD and NPMD and their longitudinal change following electroconvulsive therapy (ECT). [...]

The relatively poor simulation of the below-ground processes is a severe drawback for many ecosystem models, especially when predicting responses to climate change and management. For a meaningful estimation of ecosystem production and the cycling of water, energy, nutrients and carbon, the integration of soil processes and the exchanges at the surface is crucial. [...]
