Unimodular relativity is a theory of gravity and space-time with a fixed absolute space-time volume element, the modulus, which we suppose is proportional to the number of microscopic modules in that volume element. In general relativity an arbitrary fixed measure can be imposed as a gauge condition, while in unimodular relativity it is determined by the events in the volume. Since this seems t...

Urinary creatinine excretion, measured in 96 24-h urine specimens collected from a single subject, was less variable (CV, 9.3%) than daily urine volume (CV, 20.7%). However, a small variation in measured creatinine excretion did exist, since the observed CV of 9.3% was not explicable either on the basis of analytical error (CV for replicate determinations, 1.1%) or of collection error. Thus, 24...

Let Γ be a planar graph such that the volume function of Γ satisfies V (2n) ≤ CV (n) for some constant C > 0. Then for every vertex v of Γ and n ∈ N, there is a domain Ω such that B(v, n) ⊂ Ω, ∂Ω ⊂ B(v, 6n) and |∂Ω| n.

The e!ects of positive and negative correlation, c, between (N"100) random synaptic inputs (each "ring at 100 Hz) on the mean and coe$cient of variation (CV) of interspike interval (ISI) of the Hodgkin}Huxley model are examined, for di!erent IPSP/EPSP frequency ratios, r. Mean (ISI) and CV are approximately constant (30}40 ms, and 0.75, respectively) under independence for r3[0,1], unlike the l...

A b s t r a c t . We examine the effects of changing the coefficient of variation (CV) of the inter-stimulus interval on the CV of the output interspike interval (ISI), using constant magnitude, supra-threshold pointprocess stimuli of the membrane potential variable in the FitzHughNagumo model. The coefficient of variation of the input is changed within the context of a displaced exponential di...

Deposit volume is a critical factor for reconstructing an explosive eruption. Volume estimate models typically used for large Plinian deposits have been adapted and improved repeatedly over the last few decades. Less work has been done to refine a method for estimating the volume from smaller deposits produced by discrete phreatic and phreatomagmatic explosions. The characterization of the volu...

In this study Bis(1,4-dinitro toprop-2-yl) Nitramine, BNA, was attached to boron nitride nano- cages (B12N12). , thermodynamic parameters of BNA with B12N12 have been computed using one of the methods of density functional theory (B3LYP) In the temperature variety 300 to 400 K each 10 degree one times, were calculated. So these materials were geometrically optimized. After that thermodynamic pa...

investigation of inter-storm variability of runoff and soil loss characteristics helps experts and decision makes better understanding of hydrological response. however, this important has been less considered in the world, especially developing countries. the present study was therefore planned to evaluate the effect of different rainfall intensities and slopes on inter-storm variability of co...
