Let Mn denote a random symmetric n by n matrix, whose upper diagonal entries are iid Bernoulli random variables (which take value −1 and 1 with probability 1/2). Improving the earlier result by Costello, Tao and Vu [4], we show that Mn is nonsingular with probability 1 − O(n−C) for any positive constant C. The proof uses an inverse Littlewood-Offord result for quadratic forms, which is of inter...

Mood Swings is introduced: an affective interactive art installation that interprets and visualizes affect expressed by a person. Founded on the integration of a color model and a framework for affective movements, Mood Swings recognizes affective movement characteristics, processes these, and displays a color that matches the expressed emotion. Mood Swings was successfully evaluated by 36 muse...

analyzing the nonlinear vibration of beams is one of the important issues in structural engineering. according to this, an impressive analytical method which is called modified iteration perturbation method (mipm) is used to obtain the behavior and frequency of a cantilever beam with geometric nonlinear. this new method is combined by the mickens and iteration methods. moreover, this method don...

Torsion deformable spatial beam and Costello theory are used to establish longitudinal-torsional-lateral coupled model of round balance rope. Based on Coulomb’s friction law model, the nonlinear dynamic with constraint rope is established. Meanwhile, time-varying multi-segments non–equal-length element transformation method (TMN-ETM) proposed save computation time. Then, natural frequencies, la...

In the editorial section, Anthony Costello et al. (406) announce WHO’s collaborative effort to define the syndrome associated with congenital Zika virus infection. Islene Araujo de Carvalho et al. (407) call for papers for a special issue on innovation for healthy ageing. Michel Sidibé (408) points to an opportunity to secure funding for the next stage of the response to the human immunodeficie...
