Background and Aim: Changes in the position of the scapula due to its multiple roles, including acting as a muscle binding site and stabilization in this area can reduce the physiological and biomechanical efficiency of the shoulder, which ultimately increases shoulder injury. Therefore, the purpose of this study was to compare the functional stability of shoulder girdle between asymmetric and ...

We give a new construction of difference families generalizing Szekeres’s difference families [17]. As an immediate consequence, we obtain some new examples of difference families with several blocks in multiplicative subgroups of finite fields. We also prove that there exists an infinite family of divisible difference families with two blocks in a unit subgroup of the Galois ring GR(4, n). Fur...

In this paper, we consider a typical continuous two dimensional $\mathcal {P}\mathcal {T}$ -symmetric Hamiltonian and propose different approaches to quantitatively show the difference between η-inner products. Despite continuity of Hamiltonian, product is not in some sense. It shown that products broken unbroken -symmetry lower bounded. Moreover, such property can lead uncertainty relation.

A finite-difference method for the solution of symmetric positive linear differential equations is developed. The method is applicable to any region with piecevvise smooth boundaries. Methods for solution of the finite-difference equations are discussed. The finite-difference solutions are shown to converge at essentially the rate 0(h1'2) as h —> 0, h being the maximum distance between adjacent...
