this paper proposed analytical solutions for the buckling analysis of rectangular single-layered graphene sheets under in-plane loading on all edges simply is supported. the characteristic equations of the graphene sheets are derived and the analysis formula is based on the nonlocal mindlin plate. this theory is considering both the small length scale effects and transverse shear deformation ef...

We present a nonsupersymmetric orbifold of type II string theory and show that it has vanishing cosmological constant at the one and two loop level. We argue heuristically that the cancellation persists at higher loops.

Explaining the small observed value of the cosmological constant is one of the crucial problems in contemporary theoretical physics (see [1–3] for reviews). Although classically the value of the cosmological constant can be tuned to an arbitrarily small value, one cannot do so in a quantum theory. In general quantum fluctuations force one to relate the vacuum energy density to the UV cut-off sc...

Compactified string theories give rise to discrete symmetries which are essential if they are to provide a realistic low energy theory. We find that in a class of four dimensional string theories these symmetries are constrained by similar conditions to those discrete anomaly cancellation conditions found in the case the discrete symmetry is a residue of a spontaneously broken gauge symmetry. S...

The study presents analytical, simulation, and experimental analyses of amplitude cancellation of motor-unit action potentials (APs) in the interference electromyogram (EMG) and its relation to the size of the spike-triggered average (STA) EMG. The amount of cancellation of motor-unit APs decreases monotonically as a function of the ratio between the root mean square (RMS) of the motor-unit AP ...

The accomplishment model of average mental workload--a formal axiomatic measurement theory--was used as a basis for developing and testing secondary task indices of mental workload (H. A. Colle & G. B. Reid, 1997). Its cancellation axiom implies global sensitivity, which is an important theoretical and practical criterion for mental workload indices. Performance levels of different secondary ta...

1 . I n t r o d u c t i o n In many cases, specialiied inference rules which incorporate certain axioms into the inference mechanism can produce fewer redundant consequences and more efficient proofs. The most notable example is paramodulation. Inference rules for inequalities, partial orerings, special binary relations have also been found ([BIH80], [S1N73], [MaW85]). Recently there has also b...

We highlight what seems to be a remaining subtlety in the argument for cancellation of total anomaly associated with M5-brane M-theory. Then, we prove that this is resolved under hypothesis C-field flux charge-quantized generalized cohomology theory called J-twisted cohomotopy.

The adaptive Volterra filter has been successfully applied in nonlinear acoustic echo cancellation (AEC) systems and nonlinear line echo cancellation systems, but its applications are limited by its required computational complexity and slow convergence rate, especially for systems with long memory length. In this paper, we first apply a more general nonlinear filter, the function expansion non...
