Pronominalization and clitic doubling in Syrian and Omani Arabic by Hallman Peter, Al-Balushi Rashid

“…We trace this difference to a basic difference in whether the relevant syntactic processes are sensitive to intervention effects in the two dialects, with the result being that the restrictiveness of pronominalization and clitic pronoun doubling patterns parallel the restrictiveness of basic word order patterns – whether double-object constructions are ‘symmetric’ or ‘asymmetric’ – with Syrian being the more restrictive of the two varieties.…”

Integral Representations of Cooperative Game with Fuzzy Coalitions by Jinhui Pang, Xiang Chen

“…Classical extensions of fuzzy game models are based on various integrals, such as Butnariu game and Tsurumi game. A new class of symmetric extension of fuzzy game with fuzzy coalition variables is put forward with Concave integral, where players’ expected values are on a partial set of coalitions. …”

The Y-Index of Some Complement Graph Structures and Their Applications of Nanotubes and Nanotorus by Mohammed Alsharafi, Abdu Alameri, Yusuf Zeren, Mahioub Shubatah, Anwar Alwardi

“…This study calculates the Y-index of some graphs and complements graph operations such as join, tensor and Cartesian and strong products, composition, disjunction, and symmetric difference between two simple graphs. Moreover, the Y-polynomial of titania nanotubes and the formulae for the Y-index, Y-polynomial, F-index, F-polynomial, and Y-coindex of the HAC5C7q,p and HAC5C6C7q,p nanotubes and their molecular complement graphs have been investigated.…”

Further Results on Reachable Set Bounding for Discrete-Time System with Time-Varying Delay and Bounded Disturbance Inputs by Wei Kang, Hao Chen, Kaibo Shi, Jun Cheng

“…The main advantage of this paper lies in two aspects: first, the initial state vectors are not necessarily zero; second, the obtained criteria in this paper do not really require all the symmetric matrices involved in the employed Lyapunov-Krasovskii functional to be positive definite. …”

Irreducible Modular Representations of the Reflection Group G(m,1,n) by José O. Araujo, Tim Bratten, Cesar L. Maiarú

“…In an article published in 1980, Farahat and Peel realized the irreducible modular representations of the symmetric group. One year later, Al-Aamily, Morris, and Peel constructed the irreducible modular representations for a Weyl group of type Bn. …”

Adaptive Synchronization of Complex Networks with Mixed Probabilistic Coupling Delays via Pinning Control by Jian-An Wang

“…The coupling configuration matrices are not assumed to be symmetric or irreducible. By adding adaptive feedback controllers to a small fraction of network nodes, a low-dimensional pinning sufficient condition is obtained, which can guarantee that the network asymptotically synchronizes to a homogenous trajectory in mean square sense. …”

Testing Gaussianity, Homogeneity, and Isotropy with the Cosmic Microwave Background by L. Raul Abramo, Thiago S. Pereira

“…We focus both on isotropic estimators of nongaussianity as well as statistically anisotropic estimators of gaussianity, giving particular emphasis on their signatures and the enhanced “cosmic variances” that become increasingly important as our putative Universe becomes less symmetric. After reviewing the formalism behind some simple model-independent tests, we discuss how these tests can be applied to CMB data when searching for large-scale “anomalies”.…”

Hypersurfaces with Two Distinct Para-Blaschke Eigenvalues in Sn+1(1) by Junfeng Chen, Shichang Shu

“…Let x:M↦Sn+1(1) be an n  (n≥3)-dimensional immersed hypersurface without umbilical points and with vanishing Möbius form in a unit sphere Sn+1(1), and let A and B be the Blaschke tensor and the Möbius second fundamental form of x, respectively. We define a symmetric (0,2) tensor D=A+λB which is called the para-Blaschke tensor of x, where λ is a constant. …”
