The effect of blue-light-blocking lenses on retinal straylight

2021

Sometimes yellow-tinted lenses are recommended to help improve visual quality. As yellow lenses filter blue light, it is believed that their use could decrease the intensity of scattered light in the eye (retinal straylight). However, the results of some studies have contradicted this assumption (Van Os et al. 2017). Currently various nontinted blue-light-blocking lenses are used to protect the eyes from short-wavelength light. The objective of this study was to determine whether blue-light-blocking lenses affect the levels of retinal straylight in the eye. A straylight meter (C-Quant, Oculus) was used for retinal straylight measurements. The measurements were performed under four different…

Effects of a 10-day high-intensity interval training mesocycle on physical performance in male judo athletes

2020

Judo is an Olympic combat sport where the competition emphasizes several consecutive 20-30 seconds high-intensity efforts interspersed by short recovery periods. High-intensity block training has been found to be an efficient way to develop physical performance, wherein shorter training periods are focused on developing one or two chosen physical abilities. The purpose of this study was to investigate the effects of a 10-day high-intensity interval training period on the performance in male judo athletes. The study included pre and post-tests as well as a 10-day training intervention. The subjects were 19-28 years old men who had competed at least at the Nordic level during the last year (n…

Physiological, Perceptual, and Performance Responses to the 2-Week Block of High- versus Low-Intensity Endurance Training

2022

Purpose This study examined the physiological, perceptual, and performance responses to a 2-week block of increased training load and compared whether responses differ between high-intensity interval (HIIT) and low-intensity (LIT) endurance training. Methods Thirty recreationally trained males and females performed a two-week block of 10 HIIT-sessions (INT, n = 15) or 70 % increased volume of LIT (VOL, n = 15). Running time in the 3000 m and basal serum and urine hormone concentrations were measured before (T1) and after the block (T2), and after a recovery week (T3). In addition, weekly averages of nocturnal heart rate variability (HRV) and perceived recovery were compared to the baseline.…

Two-phase routing in three-dimensional blocked optical tori

2014

The contribution of this paper is an all-optical 3D network architecture. We describe scheduled, two-phase routing for it. The three-dimensional blocked optical torus BOT of block size b consists of b2 × b2 × b2 nodes for the first phase routing. Processors are evenly deployed at the underlying torus so that every bth node consists of a processor. Additionally, a BOT consists of b3 blocks of b × b × b subnetworks for the second phase routing. Routing of each packet is done in two phases. Firstly, packets are routed from source processor to an intermediate target node at the target block. Secondly, packets are routed from the intermediate targets at the target block to the target processor (…

Higher-order Nonnegative CANDECOMP/PARAFAC Tensor Decomposition Using Proximal Algorithm

2019

Tensor decomposition is a powerful tool for analyzing multiway data. Nowadays, with the fast development of multisensor technology, more and more data appear in higherorder (order > 4) and nonnegative form. However, the decomposition of higher-order nonnegative tensor suffers from poor convergence and low speed. In this study, we propose a new nonnegative CANDECOM/PARAFAC (NCP) model using proximal algorithm. The block principal pivoting method in alternating nonnegative least squares (ANLS) framework is employed to minimize the objective function. Our method can guarantee the convergence and accelerate the computation. The results of experiments on both synthetic and real data demonstrate …

Kriptogrāfisko valūtu ietekme uz starptautisko ekonomiku

2018

Mūsdienu pasaulē jau ir aptuveni tūkstotis dažādu kriptogrāfisko valūtu, no kurām populārākā ir bitkoins. Pieprasījums pēc šīs valūtas ir pieaudzis rekordlielā ātrumā un joprojām nav nokrities līdz tādiem skaitļiem, kādi bija pašā bitkoinu sākumā. Kriptogrāfiskās valūtas piesaista lielu uzmanību un lielākā daļa cilvēku mēģina izprast, kā tās darbojās. Pastāv daudzi viedokļi par kriptogrāfiskajām valūtām: 1. Kriptogrāfiskās valūtas noteikti mainīs pasauli. 2. Kriptogrāfiskajai valūtai piemīt burbuļa efekts un tuvākajā nākotnē tā pazudīs. 3. Kriptogrāfiskās valūtas ir jauns naudas veids, kurš sniedz dažādas priekšrocības tās lietotājiem. Gandrīz visas kriptogrāfiskās valūtas darbojās ar blokķ…

Sparse nonnegative tensor decomposition using proximal algorithm and inexact block coordinate descent scheme

2021

Nonnegative tensor decomposition is a versatile tool for multiway data analysis, by which the extracted components are nonnegative and usually sparse. Nevertheless, the sparsity is only a side effect and cannot be explicitly controlled without additional regularization. In this paper, we investigated the nonnegative CANDECOMP/PARAFAC (NCP) decomposition with the sparse regularization item using l1-norm (sparse NCP). When high sparsity is imposed, the factor matrices will contain more zero components and will not be of full column rank. Thus, the sparse NCP is prone to rank deficiency, and the algorithms of sparse NCP may not converge. In this paper, we proposed a novel model of sparse NCP w…

Targeting the Activin Receptor Signaling to Counteract the Multi-Systemic Complications of Cancer and Its Treatments

2021

Muscle wasting, i.e., cachexia, frequently occurs in cancer and associates with poor prognosis and increased morbidity and mortality. Anticancer treatments have also been shown to contribute to sustainment or exacerbation of cachexia, thus affecting quality of life and overall survival in cancer patients. Pre-clinical studies have shown that blocking activin receptor type 2 (ACVR2) or its ligands and their downstream signaling can preserve muscle mass in rodents bearing experimental cancers, as well as in chemotherapy-treated animals. In tumor-bearing mice, the prevention of skeletal and respiratory muscle wasting was also associated with improved survival. However, the definitive proof tha…
