This article considers tests for symmetry of the one-dimensional marginal distribution of fractionally integrated processes. The tests are implemented by using an autoregressive sieve bootstrap ...

In his Special Theory of Relativity, Einstein formulated the hypothesis according to which the speed of light is always the same, no matter what the conditions are. It may, however, be possible that - ...

Quantum computers promise to solve problems that overwhelm classical machines, but their most stubborn obstacle is noise that scrambles fragile quantum states before any useful answer emerges. A new ...

Objective To evaluate the association between limb symmetry index (LSI) in quadriceps and hamstrings strength together with hop tests, as a proxy of recovery, and the deviation from being symmetrical ...
