While one might assume that the force to break a chemical bond gives a measure of the bond strength, this intuition is misleading. If the force is loaded slowly, thermal fluctuations may break the bond before it is maximally stretched, and the breaking force will be less than the bond can sustain. Conversely, if the force is loaded rapidly it is more likely that the maximum breaking force is me...

We propose topological metamaterials working in Hertz frequency range, constituted of concrete pillars on the soil ground a honeycomb lattice. Based analog quantum valley Hall effect, non-trivial bandgap is formed by breaking inversion symmetry unit cell. A interface created between two different crystal phases whose robustness against various defects and disorders quantitatively analyzed. Fina...

This article describes the classification of cationic bitumen emulsions according to "reactivity" and breaking behaviour characteristics. The methods researching characteristics for different in accordance with European Ukrainian regulatory documents are presented. Available possible emulsifiers Ukraine over-stabilised given a description road technology where they can be applied. experience us...

A new way of supersymmetry breaking involving a dynamical parameter is introduced. It is independent of particle phenomenology and gauge groups. The only requirement is that Lorentz invariance be valid strictly infinitesimally (i. e. Spin(1, 3) be for some values of the parameter replaced by a compact group G with its Lie algebra g = so(1, 3)).

We construct a hybrid inflationary model associated with the superheavy scale MX ≃ 2 × 1016 GeV of the minimal supersymmetric standard model which is based on the simplest superpotential for symmetry breaking and in which the inflaton potential along the inflationary trajectory is essentially provided by quasi-canonical supergravity. The resulting spectrum of adiabatic density pertubations is b...

When CP asymmetries in B(t) → ππ are combined using broken flavor SU(3) with decay rates for B → Kπ and/or B → Kπ, one can obtain stringent limits on the weak phase γ which are consistent with those obtained from other CKM constraints. Experimental data in the past few years have improved to the extent that systematic errors associated with uncertainty in SU(3) symmetry breaking dominate the de...
