Micronutrient Status in Children Suffering From Anorexia Nervosa: A Cohort of 349 Patients in a Referral Center for Eating Disorders

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Anorexia nervosa (AN) is a serious illness in which more than half of all deaths are due to malnutrition. Critically low energy and protein intake are known causes of massive weight loss, whereas micronutrient deficiencies due to a low‐calorie food pattern remain poorly characterized in children with AN. Micronutrient deficiencies in

Frequency Comb-Based WDM Transmission Systems Enabling Joint Signal Processing

open access: yesApplied Sciences, 2018
We review the use of optical frequency combs in wavelength-division multiplexed (WDM) fiber optic communication systems. In particular, we focus on the unique possibilities that are opened up by the stability of the comb-line spacing and the phase ...

Generation of optical frequency combs with a CaF2 resonator [PDF]

open access: yes, 2009
We demonstrate optical frequency combs using the fluorite whispering gallery mode resonator as a nonlinear Kerr medium. Two regimes of generation are observed, giving the record low repetition rate of 13 GHz, equal to the cavity's free spectral range ...

Computational multiheterodyne spectroscopy

open access: yes, 2016
Dual comb spectroscopy allows for high-resolution spectra to be measured over broad bandwidths, but an essential requirement for coherent integration is the availability of a phase reference.

Inherited metabolic epilepsies–established diseases, new approaches

open access: yesEpilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Self-synchronization of Kerr-nonlinear Optical Parametric Oscillators [PDF]

open access: yes, 2016
We introduce a new, reduced nonlinear oscillator model governing the spontaneous creation of sharp pulses in a damped, driven, cubic nonlinear Schroedinger equation.

Microresonator solitons for massively parallel coherent optical communications

open access: yes, 2017
Optical solitons are waveforms that preserve their shape while propagating, relying on a balance of dispersion and nonlinearity. Soliton-based data transmission schemes were investigated in the 1980s, promising to overcome the limitations imposed by ...

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

open access: yesFlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...
