In this article, we introduce a new family of polar codes from evaluation codes, called decreasing monomial-Cartesian and prove that families with multiple kernels over certain symmetric channels can be viewed as codes. This offers unified treatment for such any finite field. We define obtained set monomials closed under divisibility Cartesian product determine their parameters (length, dimensi...

This paper proposes a new dynamic bandwidth and bandwidth allocation (DWBA) algorithm for energy saving in time and wavelength division multiplexing passive optical networks (TWDM PONs). Decreasing the number of active upstream wavelengths, the proposed algorithm not only saves power but also provides good efficiency for TWDM PON systems. Using simulations, we evaluate performance of the propos...

Heinz recently completed a comprehensive experiment in self-play using the FRITZ chess engine to establish the ‘decreasing returns’ hypothesis with specific levels of statistical confidence. This note revisits the results and recalculates the confidence levels of this and other hypotheses. These appear to be better than Heinz’ initial analysis suggests.

We demonstrate both theoretically and experimentally the generation of a tunable two-dimensional superoscillating optical field through the interference of multiple Airy beams. The resulting pattern exhibits self-healing properties for a set of sub-Fourier diffraction spots with decreasing dimensions. Such spatial optical fields might find applications in microscopy, particle manipulation, and ...

Objective: This research aimed to determine the effectiveness of cognitive group therapy on self-efficacy and depression among divorced women. Methods: This was a quasi-experimental study with pretest-posttest design with control group. In this study, all divorced women referring to Hazrate Zeinab Charity Institution in Varamin City, Iran were considered as the statistical population with a sa...

Objectives: Adolescence is a period of life in which the individuals face many mental problems concerned with mental body image. Obesity could be the cause of dissatisfaction and makes adolescents’ self-esteem to decrease. This study aimed to examine the adolescents’ satisfaction of their body image correlated to their self-esteem. Materials and Methods: In this cross-sectional study all of ...
