Positivity of Divisor Classes on the Strata of Differentials
Three decades ago Cornalba-Harris proved a fundamental positivity result for divisor classes associated to families of stable curves. In this paper we establish an analogous positivity result for divisor classes associated to families of stable differentials.
متن کاملNeuromechanical strategies employed to increase jump height during the initiation of the squat jump.
The maximal height attained in a vertical jump is heavily influenced by the execution of a large countermovement prior to the upward motion. When a jump must be executed without a countermovement, as in a squat jump, the maximal jump height is reduced. During such conditions, the human body may use other strategies in order to increase performance. The purpose of this research was to investigat...
متن کاملThe relationship of strength and jump height in figure skaters.
Eighteen junior elite figure skaters were filmed while performing axel and double axel jumps. These same skaters were assessed for strength of the shoulders, knees, and hips at multiple angular velocities using a Cybex II system. The height of the jumps was significantly correlated with the strength data. Knee extension at 240 deg/sec and shoulder abduction at 300 deg/sec were shown to be the m...
متن کاملPrediction of height and time of jump in elite female volleyball players with selected kinematic variables
Regarding the effects of the kinematics of the movement on athletic performance and the Importance of promoting athlete’s performance on the sport fields, there is limited knowledge about the mechanism of the effect of different variables of volleyball spike. Therefore, the aim of this study was the prediction of jump performance in elite female volleyball players with selected kinematic variab...
متن کاملTHE ZERO-DIVISOR GRAPH OF A MODULE
Let R be a commutative ring with identity and M an R-module. In this paper, we associate a graph to M, sayΓ(RM), such that when M=R, Γ(RM) coincide with the zero-divisor graph of R. Many well-known results by D.F. Anderson and P.S. Livingston have been generalized for Γ(RM). We Will show that Γ(RM) is connected withdiam Γ(RM)≤ 3 and if Γ(RM) contains a cycle, then Γ(RM)≤4. We will also show tha...
