The Fibonacci lengths of the finite p-groups have been studied by R. Dikici and co-authors since 1992. All of the considered groups are of exponent p, and the lengths depend on the celebrated Wall number k(p). The study of p-groups of nilpotency class 3 and exponent p has been done in 2004 by R. Dikici as well. In this paper we study all of the p-groups of nilpotency class 3 and exponent p2. Th...

The distribution function of the electrons produced in the interaction between an intense electromagnetic wave and a neutral gas is derived and is shown to be nonequilibrium and anisotropic. By assuming that the time scale of gas ionization is much greater than the field period, it is shown that the electron distribution function formed in microwave and optical discharges has sharp anisotropy a...

(pacing-induced) dogs. The sensitivity of these units was compared between the two groups of dogs. After development of clinical heart failure, the animals were anesthetized, and the left carotid sinus was vascularly isolated and perfused with oxygenated Krebs-Henseleit solution. Single-unit baroreceptor discharge was recorded from the carotid sinus nerve in response to stepwise increases in ca...

We have translated fractional Brownian motion (FBM) signals into a text based on two ”letters”, as if the signal fluctuations correspond to a constant stepsize random walk. We have applied the Zipf method to extract the ζ′ exponent relating the word frequency and its rank on a loglog plot. We have studied the variation of the Zipf exponent(s) giving the relationship between the frequency of occ...

The responses of the nested groundwater flow systems (NGFS) to rainfall fluctuations and impacts NGFS on surface runoff are explored using a fully coupled variably saturated groundwater-surface water model in conjunction with spectral analysis. Numerical experiments designed investigate fractal behaviors hydraulic head different scenarios. results show that inlets, outlets, patterns sub-systems...

The lack of water in arid and semi-arid areas has become a serious crisis, endangering living conditions. Sloping lands in the geographical and natural areas of Central Province have always been critical areas as sources of sediment production and erosion. Meanwhile, these areas provide valuable capacity for productive employment and conservation of water and soil resources through the construc...

[1] Using a stereo pair of HiRISE images of a pole‐facing crater slope at 38°S, 218°E, we measure topographic profiles along nine gullies. Typical slopes of the interior channel region (above the depositional apron) are ∼20°. We test the hypothesis that sediment transport on gully slopes occurs via fluvial transport processes by developing a numerical sediment transport model based on steep flu...

Animals optimize behaviors by predicting future critical events based on histories of actions and their outcomes. When behavioral outcomes like reward and aversion are signaled by current external cues, actions are directed to acquire the reward and avoid the aversion. The basal ganglia are thought to be the brain locus for reward-based adaptive action planning and learning. To understand the r...

Over the past decades, numerous regime formulations, describing channel width, average flow depth and channel slope, have been proposed for gravel-bed rivers. Using the downstream hydraulic geometry measurements from 280 field channels, nine gravel-bed predictive formulations were compared. They are attributed to Bray, Chang, Hey and Thorne, Kellerhals, Neil, Parker and Simons, and Albertson. T...

introduction: side weir structures are extensively used in hydraulic engineering, irrigation and environmental engineering, and it usually consists of a main weir and a lateral channel. side weirs are also used as an emergency structure. this structure is installed on one side or both sides of the main channel to divert the flow from the main channel to the side channel. lateral outflow takes p...
