Invariance of the speckle pattern of the transmitted wave in periodic waveguides.

We report on conditions of invariance of the transmitted pattern in the propagation through a periodic waveguide, the incident wave having no effect on the intensity pattern of the transmitted field. This phenomenon is reminiscent of that observed when illuminating a disordered medium in the regime of Anderson localization, as a consequence of the contribution of a single transmission eigenchannel to the transmitted wave. It is shown that the freezing of the transmitted wave is not intrinsically related to the disorder and that, whatever the frequency, it can also be observed in a regular, periodic system, provided that at most one Bloch mode is propagating.

Sacubitril/valsartan reduces proteasome activation and cardiomyocyte area in an experimental mouse model of hypertrophy.

Sacubitril/valsartan (Sac/Val) belongs to the group of angiotensin receptor-neprilysin inhibitors and has been used for the treatment of heart failure (HF) for several years. The mechanisms that mediate the beneficial effects of Sac/Val are not yet fully understood. In this study we investigated whether Sac/Val influences the two proteolytic systems, the ubiquitin-proteasome system (UPS) and the autophagy-lysosomal pathway (ALP), in a mouse model of pressure overload induced by transverse aortic constriction (TAC) and in human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) treated with endothelin-1 (ET1) serving as a human cellular model of hypertrophy.

The Power of Beliefs in Recovery-Oriented Practice: A Brief Report from the STIGMAPRO Survey.

Despite the international incentives and the worldwide development of recovery-oriented policies, it has proven challenging to establish recovery-oriented mental health services that take into account users' subjectivity and perspectives (Slade et al., World Psychiatry 13(1):12-20, 2014. https://doi.

New-generation 0.55T MRI in patients with total hip arthroplasty: a comparison with 1.5T MRI.

Purpose: To quantitatively and qualitatively compare the magnitude of metal total hip arthroplasty-induced imaging artifacts in vivo between 1.5T and 0.55T MRI.
