Based on a thermodynamic analysis of the relevant experimental data, some anomalies of the diffusion mass-transport during two-dimensional (2D) decompositioning high-temperature superconducting (HTSC) cuprates are considered. Possible mechanism for the manifestation of phase fluctuation-like effects in the HTSC cuprates, especially with respect to the physical properties of melt-textured compos...

The kinetics of chlorophyll fluorescence were measured in Portulacaria afra (L.) Jacq. when the plants were functioning in either Crassulacean acid metabolism (CAM) or C(3)/CAM cycling (called cycling) modes, as determined by fluctuation in titratable acidity and gas exchange properties. Cycling plants showed primarily daytime CO(2) uptake typical of C(3) plants, but with a slight diurnal acid ...

Germination provides many potentially unrecognized sources of variation in the regeneration niche. In this study we relate germination requirements and seed size for 16 species of pioneer trees to microclimatic conditions present in gaps in semi-deciduous rain forest in Panama. We found that, whereas increased duration of direct irradiance can be an effective indicator of the presence of a cano...

We calculate the maximum fraction of matter which is able to condense out of the expanding background universe by gravitational instability – the asymptotic collapsed fraction – for any universe which is unbound and, hence, will expand forever. We solve this problem by application of a simple, pressure-free, spherically symmetric, nonlinear model for the growth of density fluctuations in the un...

In this paper, the dynamic behavior of a self-propelled droplet along conical fiber is simulated by using an improved lattice Boltzmann color-gradient method. This method developed on basis our recently density ratio model [Zhang et al., Int. Commun. Heat Mass Transfer, 137, 106284 (2022).], but wetting boundary condition added to account for moving contact line arbitrary solid surface. First, ...

We study small fluctuations around a BPS three-sphere vacuum solution of mass deformed BLG theory. We realize the BLG theory by a Nambu bracket and find a maximally supersymmetric lagrangian for the fluctuation fields corresponding to a single M5 brane on R × S. [email protected]

Inflation drives quantum fluctuations beyond the Hubble horizon, freezing them out before small-scale modes re-enter during radiation dominated epoch, and subsequently decay, while large-scale later matter epoch grow. This distinction shapes power spectrum provides observational evidence in support of standard model. In this paper, we demonstrate that another mechanism, based on fluctuation gro...

The metabolic cost of walking is determined by many mechanical tasks, but the individual contribution of each task remains unclear. We hypothesized that the force generated to support body weight and the work performed to redirect and accelerate body mass each individually incur a significant metabolic cost during normal walking. To test our hypothesis, we measured changes in metabolic rate in ...

Leu+ mutants from Salmonella typhimurium leu-500 strain MA412 arise at high frequencies and mutant colonies appear over a broad range of time on selective plates. This observation suggested that these Leu+ mutants might be induced or "directed."= If such a mechanism was responsible, mutants should originate on selective plates rather than in the preceding culture in nonselective conditions and ...
