Association of sleep timing and sleep variability with health-related outcomes in a sample of Brazilian adolescents.

Objectives: This cross-sectional study aimed to examine the relationships of sleep timing and sleep variability with depressive symptoms, health-related quality of life (HRQoL), daytime sleepiness, and body mass index (BMI) in adolescents.

Methods: Adolescents from three schools ( = 571, 56% female, 16.3 ± 1.

Sleep timing and health indicators in children and adolescents: a systematic review.

Introduction: To continue to inform sleep health guidelines and the development of evidence-based healthy sleep interventions for children and adolescents, it is important to better understand the associations between sleep timing (bedtime, wake-up time, midpoint of sleep) and various health indicators. The objective of this systematic review was to examine the associations between sleep timing and 9 health indicators in apparently healthy children and adolescents 5 to 18 years old.

Methods: Studies published in the 10 years preceding January 2021 were identified from searches in four electronic databases.

Cerambycid Beetle Communities in Caatinga Dry Forests Are Structured by Seasonal Species Turnover.

Dry forests in the Caatinga biome of Brazil are seasonal ecosystems where diversity is driven by water availability. Understanding how the distribution of communities is driven by temporal climate changes has intrigued researchers for decades. However, temporal diversity patterns should be more evident in dry environments, since seasonality is characterized by being highly limiting to insect activities.

Reply to "Comment on 'Deformed Fokker-Planck equation: Inhomogeneous medium with a position-dependent mass"'.

It is shown that in the "Comment on 'Deformed Fokker-Planck equation: Inhomogeneous medium with a position-dependent mass,"' three crucial observations have gone unnoticed, thus restricting its conclusion on the legitimacy of the Langevin equation for a position-dependent mass, Eq. (46) of da Costa et al. [Phys.

Deformed Fokker-Planck equation: Inhomogeneous medium with a position-dependent mass.

We present the Fokker-Planck equation (FPE) for an inhomogeneous medium with a position-dependent mass particle by making use of the Langevin equation, in the context of a generalized deformed derivative for an arbitrary deformation space where the linear (nonlinear) character of the FPE is associated with the employed deformed linear (nonlinear) derivative. The FPE for an inhomogeneous medium with a position-dependent diffusion coefficient is equivalent to a deformed FPE within a deformed space, described by generalized derivatives, and constant diffusion coefficient. The deformed FPE is consistent with the diffusion equation for inhomogeneous media when the temperature and the mobility have the same position-dependent functional form as well as with the nonlinear Langevin approach.

Majorization and Dynamics of Continuous Distributions.

In this work we show how the concept of majorization in continuous distributions can be employed to characterize mixing, diffusive, and quantum dynamics along with the -Boltzmann theorem. The key point lies in that the definition of majorization allows choosing a wide range of convex functions ϕ for studying a given dynamics. By choosing appropriate convex functions, mixing dynamics, generalized Fokker-Planck equations, and quantum evolutions are characterized as majorized ordered chains along the time evolution, being the stationary states the infimum elements.

Patterns of risk behaviors in Brazilian older adults: A latent class analysis.

Aim: The aim of the present study was to describe the clustering of diet, physical activity, television viewing, and tobacco and alcohol use among Brazilian older adults (aged ≥60 years).

Methods: We carried out a secondary analysis of the Brazilian National Health Survey of 2013. Brazilian older adults (n = 11 177) reported their consumption of fruit and vegetables, leisure physical activity, television viewing, tobacco smoking, and alcohol intake.

Sedentary behavior during school-time: Sociodemographic, weight status, physical education class, and school performance correlates in Brazilian schoolchildren.

Objectives: To investigate whether sedentary behavior during school-time is associated with gender, age, mother's education, having physical education classes, weight status, and academic performance.

Design: Cross-sectional study.

Methods: A sample of 571 children (7-12 years old) from five elementary schools in Florianopolis, South Brazil had their height and weight measured, and wore accelerometers during class time.
