We elucidate the polymer dynamics of a liquid crystal elastomer based on the time-dependent response of the pendent liquid crystal mesogens. The molecular tilt and switching time of mesogens are analyzed as a function of temperature and cross-linking density upon application of an electric field. We observe an unexpected maximum in the switching time of the liquid crystal mesogens at intermedia...

• Let G be a graph. For subset X of V ( ), the switching σ is signed graph obtained from by reversing signs all edges between and ) ∖ . A( adjacency matrix An eigenvalue called main if it has an eigenvector sum whose entries not equal to zero. Two equivalent graphs share same spectrum, while they may have different eigenvalues. Akbari et al. (2021) conjectured that let ≠ K 2 , 4 { e } Then ther...

Cationic dextran hydrogels having pendent 51-59 mol% N-alkyl-N,N-dimethylammonium chloride groups were synthesized and tested as adsorbents for sodium cholate. The bile acid salt sorption by these gels was evaluated equilibrium analysis in water 10 mM NaCl solution. best adsorption results obtained with amphiphilic dextran-based two types of pendant ammonium different polarities. Experimental d...

the aim of this study was to investigate anthropometric and physiological characteristics in junior volleyball players for talent identification according to their volleyball playing positions. 15 junior national volleyball players (mean age 17.7±0.3 years) participated in this study. players were classified to five groups according to their playing positions: setters, liberoes, middle blockers...

The virtual computers VC paradigm enables the in corporation of predictability and choice into the de sign of an operating system Predictability refers to the ability of the system to provide each user with a computing environment whose performance is inde pendent of the behavior of other users Choice refers to the ability of a user to select a computer system that meets that user s speci catio...

The energy of a graph is the sum of the absolute values of the eigenvalues of its adjacency matrix. The edge grafting operation on a graph is a kind of edge moving between the two pendent paths starting from the same vertex. In this paper we show how the graph energy change under the edge grafting operations. As the applications of this grafting method, we also obtain some new results on a conj...

The energy E(G) of a graph G is defined as the sum of the absolute values of its eigenvalues. Let S2 be the star of order 2 (or K2) and Q be the graph obtained from S2 by attaching two pendent edges to each of the end vertices of S2. Majstorović et al. conjectured that S2, Q and the complete bipartite graphs K2,2 and K3,3 are the only 4 connected graphs with maximum degree ∆ ≤ 3 whose energies ...
