The requirements for automotive lighting systems,especially the light patterns ensuring driver perception,are based on criteria related to the headlamps,rather than the light perceived by drivers and road users.Consequently,important factors such as pavement reflectance,driver age,or time of night,are largely ignored.Other factors such as presence of other vehicles,vehicle speed and weather conditions are considered by the Adaptive Driving Beam(ADB)and Adaptive Front-lighting system(AFs)respectively,though with no information regarding the visual perception of drivers and other road users.Evidently,it is simpler to simulate and measure the light emitted by the lamps than the light reflected by the pavement or emitted by other vehicles.However the current technology in cameras and light sensors,communication protocols,and control of Light Emitting Diodes(LED),combined with decision-making techniques applied to large amounts of data,can open a new era in the operation of headlamps and thus ensure the visual needs of drivers in real time and under actual road conditions.The solution lies in an interaction road-sensor-headlamp,which is not based on the light emitted by headlamps,but rather on the light perceived by the drivers.This study thus proposes a dual grid based on luminance and luminous intensity,which would manage the headlamps by optimizing driver perception and the safety of all road users.

In this paper,we deal with questions related to blockchains in complex Internet of Things(IoT)-based ecosystems.such ecosystems are typically composed of IoT devices,edge devices,cloud computing software services,as well as people,who are decision makers in scenarios such as smart cities.Many decisions related to analytics can be based on data coming from IoT sensors,software services,and people.However,they are typically based on different levels of abstraction and granularity.This poses a number of challenges when multiple blockchains are used together with smart contracts.This work proposes to apply our concept of elasticity to smart contracts and thereby enabling analytics in and between multiple blockchains in the context of IoT.We propose a reference architecture for Elastic smart Contracts and evaluate the approach in a smart city scenario,discussing the benefits in terms of performance and self-adaptability of our solution.

Although complexation with soil organic matter may improve zinc(Zn)bioavailability to plants,the effect of Zn sorbent surface on the use of complexed Zn by plants remains unknown.The objective of this research was to elucidate how Zn complexation with humic substances(Hs)and phytate affects the uptake of Zn by wheat plants depending on the main sorbent surface in growth media,i.e.,carbonates and Fe oxides.To this end,two pot experiments were performed,one using Fe oxide-coated siliceous as the siliceous growth medium sand and the other using a mixture of calcareous sand and siliceous sand as the calcareous growth medium.Each experiment involved three Zn sources,Zn-Hs complex,Zn phytate,and ZnsO_(4).All sources were applied with surface irrigation at two Zn rates(0.25 and 2 mg kg^(-1) growth medium).The Zn-Hs complex significantly increased Zn uptake by plants in both media,relative to the other two Zn sources,but no significant difference was observed between Zn phytate and ZnsO_(4).In the calcareous medium,Zn-Hs complex and Zn phytate resulted in significantly higher dry biomass yields of wheat than ZnsO_(4).In the siliceous medium,spike and shoot dry biomass yields with Zn-Hs complex at the low rate and Zn phytate at both rates were not significantly different from those with ZnsO_(4) at the high rate.After harvest,approximately 50%of the Zn applied as Zn-Hs complex remained extractable by diethylenetriaminepentaacetic acid(DTPA),while this proportion was less than 20%for the other Zn sources.Thus,Zn-Hs complex and Zn phytate are sources of available Zn for plants,and they are more effective than ZnsO_(4) in increasing plant growth,particularly when carbonates are the main Zn sorbent surface.

Background:Athletes tend to have better visuo-motor performance than do sedentary individuals.However,several basic visual-function and perceptual parameters remain unexplored to date.In this study,we investigated whether differences exist in visual function,performance,and processing between basketball players and individuals without a sport-involvement background.Methods:A total of 33 healthy men with no visual impairment or pathology were divided into 2 groups,depending on the involvement in sport(semi-professional basketball players and sedentary individuals).We tested their baseline heart-rate variability in the resting position apart from subjective questionnaires to determine their physical fitness level,and we checked their visual function,performance,and processing through an extended battery of optometric tests.Results:The 2 groups differed in resting heart-rate variability parameters(pssimilarities in regular time practising sports per week.The basketball players showed a closer breakpoint and recovery nearpoint of convergence,a higher fusional-vergence rate,better discriminability halos,and better eye-hand coordination(all p valuession:These results show evidence that athletes,basketball players in this case,exhibit better performance in several visual abilities in comparison to a group of individuals without sporting backgrounds,suggesting an improvement due to the systematic involvement of those skills during basketball practice.

Background:This study investigates the effects of exercise training on exerkines in patients with type 2 diabetes mellitus to determine the optimal exercise prescription.Methods:A systematic search for relevant studies was performed in 3 databases.Randomized controlled trials investigating the effects of exercise training on at least one of the following exerkines were included:adiponectin,apelin,brain-derived neurotrophic factor,fetuin-A,fibroblast growth factor-21,follistatin,ghrelin,interleukin(IL)-6,IL-8,IL-10,IL-15,IL-18,leptin,myostatin,omentin,resistin,retinol-binding protein 4,tumor necrosis factor-α,and visfatin.Results:Forty randomized controlled trials were selected for data extraction(n=2160).Exercise training induces changes in adiponectin,fetuin-A,fibroblast growth factor-21,IL-6,IL-10,leptin,resistin,and tumor necrosis factor-a levels but has no significant effects on apelin,IL-18,and ghrelin compared to controls.Physical exercise training favored large and positive changes in pooled exerkines(i.e.,an overall effect size calculated from several exerkine s)(Hedge’s g=1.02,95%confidence interval(95%CI):0.76-1.28),which in turn were related to changes in glycated hemoglobin(mean difference(MD)=-0.81%,95%CI:-0.95%to-0.67%),fasting glucose(MD=-23.43 mg/dL,95%CI:-30.07 mg/dL to-16.80 mg/dL),waist circumference(MD=-3.04 cm,95%CI:-4.02 cm to-2.07 cm),and body mass(MD=-1.93 kg,95%CI:-2.00 kg to-1.86 kg).slightly stronger effects were observed with aerobic,resistance,or high-intensity interval protocols at moderate-to vigorous-intensity and with programs longer than 24 weeks that comprise at least 3 sessions per week and more than 60 min per session.Conclusion:Exercise training represents an anti-inflammatory therapy and metabolism-improving strategy with minimal side effects for patients with type 2 diabetes mellitus.

Oligodendrocytes(OLs),glial cells that provide myelin sheaths to axons in the central nervous system(CNs),have a dual role.First,this myelin fatty cover around the axons protects the nerves and is crucial for the saltatory propagation of action potentials.second and not less important,OLs provide trophic support to neurons and axons.Thus,OL metabolism is important for OL well-being and the proper accomplishment of their functions,and OL metabolism energetics directly affect the energy metabolism of neighboring neurons.

Purpose:The aim of the present study was to determine the association between adherence to the 24-h movement guidelines during middle adolescence and glucose outcomes(glycated hemoglobin and fasting glucose)and type 2 diabetes mellitus(T2DM)in adulthood,14 and 22 years later.Methods:We analyzed data from apparently healthy adolescents aged 12-18 years who participated in WavesⅠandⅡ(1994-1996,n=14,738),WaveⅣ(2008-2009,n=8913),and Wave V(2016-2018,n=3457)of the National Longitudinal study of Adolescent to Adult Health(Add Health)in the United states.Physical activity,screen time,and sleep duration were measured using questionnaires,and the 24-h guidelines were defined as:5 or more times moderate-to-vigorous physical activity per week,≤2 h per day of screen time,and 9-11 h of sleep for 12-13 years and 8-10 h for 14-17 years.Capillary and venous whole blood was collected and analyzed to determine glycated hemoglobin and fasting glucose for WavesⅣandⅤ,respectively.Results:Only 2.1%of the adolescents met all the 3 guidelines,and 37.8%met none of them.In both wavesⅣandⅤ,adolescents who met physical activity and screen time guidelines had lower odds of T2DM in adulthood than those who did not meet any of these guidelines(WaveⅣ;prevalence ratio(PR)=0.57,95%confidence interval(95%CI):0.21-0.89;Wave V:PR=0.43,95%CI:0.32-0.74).Only for Wave V did adolescents who met all 3 guidelines have lower odds of T2DM at follow-up compared with those who did not meet any of these guidelines(PR=0.47,95%CI:0.24-0.91).Also,for each increase in meeting one of the 24-h recommendations,the odds of T2DM decreased by 18%(PR=0.82,95%CI:0.61-0.99)and 15%(PR=0.85,95%CI:0.65-0.98)in adulthood for WavesⅣandⅤ,respectively.Conclusion:Promoting all 24-h movement guidelines in adolescence,especially physical activity and screen time,is important for lowering the potential risk of T2DM in adulthood.

Background:There is a growing body of experimental evidence examining the effects of plyometric jump training(PJT)on physical fitness attributes in basketball players;however,this evidence has not yet been comprehensively and systematically aggregated.Therefore,our objective was to meta-analyze the effects of PJT on physical fitness attributes in basketball players,in comparison to a control condition.Methods:A systematic literature search was conducted in the databases PubMed,Web of science,and scopus,up to July 2020.Peer-reviewed controlled trials with baseline and follow-up measurements investigating the effects of PJT on physical fitness attributes(muscle power,i.e.,jumping performance,linear sprint speed,change-of-direction speed,balance,and muscle strength)in basketball players,with no restrictions on their playing level,sex,or age.Hedge’s g effect sizes(Es)were calculated for physical fitness variables.Using a random-effects model,potential sources of heterogeneity were selected,including subgroup analyses(age,sex,body mass,and height)and single training factor analysis(program duration,training frequency,and total number of training sessions).Computation of metaregression was also performed.Results:Thirty-two studies were included,involving 818 total basketball players.significant(psmall-to-large effects of PJT were evident on vertical jump power(Es=0.45),countermovement jump height with(Es=1.24)and without arm swing(Es=0.88),squat jump height(Es=0.80),drop jump height(Es=0.53),horizontal jump distance(Es=0.65),linear sprint time across distances≤10 m(Es=1.67)and>10 m(Es=0.92),change-of-direction performance time across distances≤40 m(Es=1.15)and>40 m(Es=1.02),dynamic(Es=1.16)and static balance(Es=1.48),and maximal strength(Es=0.57).The meta-regression revealed that training duration,training frequency,and total number of sessions completed did not predict the effects of PJT on physical fitness attributes.subgroup analysis indicated greater improvements in older compared to younger players in horizo
