TL;DR: Nocturnal melatonin supplementation during an intensive TC alleviated oxidative stress, leukocytosis and cellular damage and improved recovery of RSA performance in soccer players.
Abstract: An optimal recovery between training sessions is of similar if not greater importance as the training content and program of the training, itself. One of the most used strategies for improving reco...

TL;DR: In this paper, the authors define and study a new class of sampling designs: determinantal sampling designs, and compute exactly the variance of linear estimators constructed upon these designs by using first and second order inclusion probabilities.
Abstract: In this article, recent results about point processes are used in sampling theory. Precisely, we define and study a new class of sampling designs: determinantal sampling designs. The law of such designs is known, and there exists a simple selection algorithm. We compute exactly the variance of linear estimators constructed upon these designs by using the first and second order inclusion probabilities. Moreover, we obtain asymptotic and finite sample theorems. We construct explicitly fixed size determinantal sampling designs with given first order inclusion probabilities. We also address the search of optimal determinantal sampling designs.

TL;DR: This work proposes a polarization-free multi-bit coding metasurface that allows for overcoming anti-symmetrical response characteristics between orthogonal circularly polarized states to enable achieving identical functionality under both right-handed and left-handed circularly polarization wave illuminations and avoiding polarization-conversion losses.
Abstract: In this work, a polarization-free coding metasurface is proposed to manipulate circularly polarized waves. Compared to a Pancharatnam-Berry phase metasurface, the proposed design not only allows for overcoming anti-symmetrical response characteristics between orthogonal circularly polarized states to enable achieving identical functionality under both right-handed and left-handed circularly polarized wave illuminations and avoiding polarization-conversion losses but also offers additional degree of freedom in the control of handedness. As a proof-of-concept demonstration, a polarization-free multi-bit coding metasurface is designed to realize helicity-switched holograms in the microwave region. Experimental measurements performed on a fabricated prototype reveal outstanding imaging quality with extremely high imaging efficiency above 76% for arbitrary polarizations at 10 GHz. Our proposed method expands the route in manipulating circularly polarized waves and can be applied over the whole electromagnetic spectrum for wavefront manipulation.

TL;DR: In this paper, the role of expertise in the use of raised line materials and visual experience by blind adults (congenitally, ear, eye, and sight) was examined.
Abstract: The purpose of this research was to examine the role of expertise (as a result of previous training) in the use of raised line materials, and of visual experience by blind adults (congenitally, ear...

TL;DR: In this paper, an institution of last resort is proposed to supervise the behavior of individuals and communities to prevent capture of public wealth by individual interests, to solve conflicts among claims and local regulations, to guarantee enforcement when exclusive rights of use are legitimate.
Abstract: Digital Technologies make it possible to decentrally settle institutional frameworks based on self-implementation of exclusive rights of use over information and on the self-regulation of on-line communities. Through a decentralized system of IPRs and collective rules setting of this kind agents would benefit from coordination frames well adapted to their specific needs and preferences. However, such a process can also result in inefficiencies. While becoming subject to exclusion, information and coordination spaces remain non-divisible goods. Moreover, individual and group interests could succeed in taking non-contestable control over "privatized" information spaces. To overcome these weaknesses and threats, an institution of last resort - placed above the agents and the self-regulated communities - should be created and make enforceable constitutional principles with the purpose of guaranteeing some fundamental rights of contents to producers and users. Based on the principle of subsidiarity, it should supervise the behavior of individuals and communities to prevent capture of public wealth by individual interests, to solve conflicts among claims and local regulations, to guarantee enforcement when exclusive rights of use are legitimate. The way to implement it is uncertain, however, since neither a central authority of last resort nor a global community exists to implement it. A combination of open, centralized negotiations among public and private norm setters with a conflict settlement mechanism aimed at harmonizing the proliferating orders could nevertheless lead to the progressive definition of such constitutional basic rights and principles.
