Strict inequalities for some critical exponents in two-dimensional percolation
For 2D percolation we slightly improve a result of Chayes and Chayes to the effect that the critical exponentβ for the percolation probability isstrictly less than 1. The same argument is applied to prove that if

On Almost Sure Sample Stability of Nonlinear Ito Differential Equations
The classic stability studies for linear Ito differential equations were developed by Khasminskii in the 1960’s. The main concept is to norm the solution and study the properties of the normed vector on the su...

The role of fitness on VO2 and VCO2 kinetics in response to proportional step increases in work rate
The purpose of this study was to determine the effect of fitness and work level on the O2 uptake and CO2 output kinetics when the increase in work rate step is adjusted to the subject's maximum work capacity. Nin...

The tortuosity of occupied crossings of a box in critical percolation
We consider the length of an occupied crossing of a box of size [0,n]×[0, 3n] D−1 (in the short direction) in standard (Bernoulli) bond percolation on ℤ D at criticality. Let ¦s

A method for estimating bicarbonate buffering of lactic acid during constant work rate exercise
A method to estimate the CO2 derived from buffering lactic acid by HCO3 − during constant work rate exercise is described. It utilizes the simultaneous continuous measurement of O2 uptake (

The Effects of Mechanical Alloying of C60 with Metals (II): Al and Mg.
C60 has been subjected to multiple micro-alloying passes by co-rolling together with Al and Mg. Complete amorphization has been found in samples of C60 with Al. However, the structural changes in the C60/Mg combi...

The Binary Phase Diagram Naphthalene-C6O
Molten naphthalene has considerable solubility for C60 (~5 ⊙ 10−3 in mole fraction) making it a potential solvent for fullerenes; the phase diagram is therefore important. It was also of interest to study whether...

Stability and Robustness Analysis of Dynamic Inversion Control Laws for Nonlinear Control of Fighter Aircraft
Aircraft dynamics are well modeled by a standard system of nonlinear ODEs (cf. [6] and [13]). Experience in industry shows that pilot simulations based on these nonlinear finite-dimensional models are very good.
