The schemes for the generation of surrogate data in order to test the null hypothesis of linear stochastic process undergoing nonlinear static transform are investigated as to their consistency in representing the null hypothesis. In particular, we pinpoint some important caveats of the prominent algorithm of amplitude adjusted Fourier transform surrogates (AAFT) and compare it to the iterated ...

purpose: to investigate the effects of sodium bicarbonate (nahco3) on exhaustive activity and physiological parameters of fatigue in conscripts. materials and methods: thirty conscripts did wingate test in two groups: sodium bicarbonate group (treatment) and placebo (control) group. in both groups, sodium bicarbonate (0.3 g/kg of body mass) or placebo was ingested 60 minutes before the training...

background: fatty acids play various physiological roles in the organism; they are crucial for the structure of cell membranes, metabolic processes, transmission of nerve impulses and brain functions. in recent years, particular attention has been paid to the rich sources of omega‑3 for the treatment of many diseases, especially mental illnesses. the present study aimed to investigate the effec...
