A skilled string performer is able to play a series of spiccato notes (short strokes played by a bouncing bow) with each onset showing little or no aperiodic motion before a regular slip/stick pattern (Helmholtz motion) is triggered. Kinematic analysis reveals that a well-behaving bow gives nearly vertical impacts on the string, and that the first slip of each note takes place when the normal b...

Background: Obesity leads to a wide range of problems. Hence, this research was conducted to compare the trait-state anxiety as well as positive and negative affect in obese and normal women. Materials and Methods: This descriptive study was performed in eight sports clubs within the time period of 2017 to 2018 in Ahvaz. To do this, a sample of 200 women, who referred to sports clubs was selec...

Estimation of change-point locations in the broken-stick model has significant applications in modeling important biological phenomena. In this article we present a computationally economical likelihood-based approach for estimating change-point(s) efficiently in both cross-sectional and longitudinal settings. Our method, based on local smoothing in a shrinking neighborhood of each change-point...

Abstract We report the properties of more than 800 bursts detected from repeating fast radio burst (FRB) source FRB 20201124A with Five-hundred-meter Aperture Spherical Telescope (FAST) during an extremely active episode on UTC 2021 September 25–28 in a series four papers. In this second paper series, we study energy distribution 881 (defined as significant signals separated by dips down to noi...

abstract in recent years, many researchers have attempted to estimate the soil hydraulic functions (e.g. soil moisture characteristics curve, and hydraulic conductivity function) using particle-size distribution (psd) curve. in these studies, an accurate mathematical representation of psd is required for fitting the observed data. so far, some mathematical models were developed with different l...
