Deep Learning Methods in Soft Robotics: Architectures and Applications

open access: yesAdvanced Intelligent Systems, EarlyView.
Soft robotics has seen intense research over the past two decades and offers a promising approach for future robotic applications. However, standard industrial methods may be challenging to apply to soft robots. Recent advances in deep learning provide powerful tools to analyze and design complex soft machines that can operate in unstructured ...

Geometric phase Doppler effect: when structured light meets rotating structured materials.

open access: yesOptics Express, 2017
We examine the geometric phase Doppler effect that appears when a structured light interacts with a rotating structured material. In our scheme the structured light possesses a vortex phase and the structured material works as an inhomogeneous ...

Phenotypical Characterization of Gastroenterological and Metabolic Manifestations in Patients With Williams–Beuren Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Gastrointestinal (GI) symptoms are common in patients with Williams–Beuren syndrome (WBS), but their prevalence and possible causes are not yet fully known. This study assessed GI symptoms' prevalence and their possible origin by performing a predefined set of tests in adult WBS patients.

Propagation of signals in spaces with affine connections and metrics as models of space-time [PDF]

open access: yesFiz.Elem.Chast.Atom.Yadra 35 (2004) 1185-1258; Phys.Part.Nucl. 35 (2004) 633-674, 2003
The propagation of signals in space-time is considered on the basis of the notion of null (isotropic) vector field in spaces with affine connections and metrics as models of space or of space-time. The Doppler effect is generalized for these types of spaces.

Description of unilateral kidney embolism and contralateral nephrectomy as a less invasive remnant kidney model in cats; a proof‐of‐concept study

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Unilateral, minimally invasive, renal arterial embolization and delayed contralateral nephrectomy was described in cats as a novel remnant kidney model of chronic kidney disease using two doses of embolic particles. Renal function declined and characteristic histopathological markers of kidney disease were present 6 months after the embolism procedure.

Cyclic Alternating Pattern Dynamics in Individuals at Risk for Developing Parkinson's Disease

open access: yesAnnals of Neurology, EarlyView.
Objective The objective of this study was to investigate the differences in cyclic alternating patterns (CAP) metrics, a non‐rapid eye movement (NREM) sleep physiological rhythm, among recently diagnosed patients with Parkinson's disease (PD), and individuals at high and low risk for developing PD based on genetic and prodromal risk.
