We conduct numerical simulations of random packings of frictionless particles at T = 0. The packing fraction where the pressure becomes nonzero is the same as the jamming threshold, where the static shear modulus becomes nonzero. The distribution of threshold packing fractions narrows, and its peak approaches random close packing as the system size increases. For packing fractions within the pe...

Due to the significant number of distributed generators in electric power system, islanding detection requirements are becoming an increasingly prominent aspect system. The island system depends on accurate threshold determination since incorrect might result a hazardous situation. To evaluate proposed method’s capacity discriminate between different events, this study examined unintentional co...

It was recently found that cascading failures can cause the abrupt breakdown of a system of interdependent networks. Using the percolation method developed for single clustered networks by Newman [Phys. Rev. Lett. 103, 058701 (2009)], we develop an analytical method for studying how clustering within the networks of a system of interdependent networks affects the system’s robustness. We find th...

The already published reference values for cardiopulmonary exercise test (CPET) might not be representative for our population. Our aim is to create reference values for CPET in children and adolescents in northwest Croatia. Exercise testing according to modifi ed Bruce treadmill protocol was performed in 164 healthy children aged 11-17 years. Results are presented as mean and standard deviatio...

We present an analytical approach to determining the expected cascade size in a broad range of dynamical models on the class of random networks with arbitrary degree distribution and nonzero clustering introduced previously in [M. E. J. Newman, Phys. Rev. Lett. 103, 058701 (2009)]. A condition for the existence of global cascades is derived as well as a general criterion that determines whether...

A class of distribution free multiple decision statistical procedures is proposed for threshold graph identification in a complete weighted graph associated with a set of random variables (random variables network). The decision procedures are based on simultaneous application of sign statistics. It is proved that single step, step down Holm and step up Hochberg statistical procedures for thres...

We explored experimentally how threshold uncertainty affects coordination success in a threshold public goods game. Whereas all groups succeeded in providing the public good when the exact value of the threshold was known, uncertainty was generally detrimental for the public good provision. The negative effect of threshold uncertainty was particularly severe when it took the form of ambiguity, ...
