Objective(s): to investigate the chronopharmacological effects of growth hormone on executive function and the oxidative stress response in rats. Materials and Methods: Fifty male Wistar rats (36-40 weeks old) had ad libitum access to water and food and were separated into four groups: diurnal control, nocturnal control, diurnal GH-treated, and nocturnal GH-treated animals. Levels of Cu, Zn sup...

We review the status of experiments and ideas relevant for the detection of the dark matter which is suspected to be the dominant constituent of the Universe. Great progress is being made and the chances are non-negligible that one of the many currently in-progress experiments will discover the nature of the dark matter. We discuss the main dark matter candidates, and review the experiments rel...

We analyzed diurnal variations in precipitation, surface pressure, and atmospheric static energy over the United States from observations and NCAR regional climate model (RegCM) simulations. Consistent with previous studies, the mean (1963-1993) pattern of the diurnal cycle of summer U.S. precipitation is characterized by late afternoon maxima over the Southeast and the Rocky Mountains and midn...

We present a robust method to classify swimming styles from live video based on the features extracted from the upper-body of the swimmer. In our approach, potential body parts are first extracted using a simple skin color model. Next, the dominant components in the segmented regions are selected according to quantitative measures such as the aspect ratio and the area. Regression analysis is pe...

The masses of two-gluon glueballs are studied with a semirelativistic potential model whose interaction is a scalar linear confinement supplemented by a one-gluon exchange mechanism. The gluon is massless but the leading corrections of the dominant part of the Hamiltonian are expressed in terms of a state-dependent constituent gluon mass. The Hamiltonian depends only on three parameters: the st...

Light use efficiency (LUE) models are widely used to estimate gross primary productivity (GPP), a dominant component of the terrestrial carbon cycle. Their outputs are very sensitive to LUE. Proper determination of this parameter is a prerequisite for LUE models to simulate GPP at regional and global scales. This study was devoted to investigating the ability of the photochemical reflectance in...

Cloud fraction (CF) is known as the dominant modulator of Earth’s radiative fluxes. Ground-based CF observations are useful to characterize the cloudiness of a specific site and are valuable for comparison with satellite observations and numerical models. We present for the first time CF statistics (relative to liquid clouds only) for Bern, Switzerland, derived from the observations of a ground...

Diurnal variations of upper tropospheric humidity (UTH) as well as middle tropospheric humidity (MTH) were examined in conjunction with the diurnal cycle of convection over tropical Africa and the adjacent tropical Atlantic Ocean using Meteosat-8 measurements. Cloud and humidity features were also tracked to document the diurnal variations of humidity and clouds in the Lagrangian framework. A d...

The functioning of the genome is tightly related to its architecture. Therefore, understanding the relationship between different regulatory mechanisms and the organization of chromosomal domains is essential for understanding genome regulation. The majority of imprinted genes are assembled into clusters, share common regulatory elements, and, hence, represent an attractive model for studies of...
