THE BROKEN PHASE OF THE TOPOLOGICAL σ MODEL [PDF]
The topological σ model with the semi-infinite cigar-like target space (black hole geometry) is considered. It is shown to possess unsuppressed instantons. The noncompactness of the moduli space of these instantons is responsible for an unusual physics.

Evolution of sigma phase precipitates in Cu-containing 25Cr–20Ni austenitic stainless steels
This study investigated, for the first time, the influence of Cu addition on sigma phase precipitation during aging at 700 °C in recrystallized 25Cr–20Ni austenitic stainless steels containing up to 2.9 wt% Cu.

Influence of the Solution-Treatment Temperature and Short Aging Times on The Electrochemical Corrosion Behaviour of Uns S32520 Super Duplex Stainless Steel [PDF]
Sigma phase leads to deterioration of corrosion resistance of super duplex stainless steels (SDSS) and its volume fraction increases as the time which the materials is exposed in determined temperature increases.

INSTANTON DYNAMICS IN THE BROKEN PHASE OF THE TOPOLOGICAL SIGMA MODEL [PDF]
The topological σ model with the black hole metric of the target space is considered. It has been shown before that this model is in the phase with BRST symmetry broken. In particular, the vacuum energy is nonzero and correlation functions of observables show the coordinate dependence. However, these quantities turn out to be infrared-divergent. It is

Hydrogen effect on the sigma-phase in Fe53.8Cr46.2 [PDF]
Abstract Investigation of the stability and properties of a sigma-phase type compound Fe 53.8 Cr 46.2 after electrochemical hydrogen treatment was made using X-ray diffraction and 57 Fe Mossbauer spectroscopy techniques. The amount of the hydrogen uptake was estimated to be equal to ∼1.2H per unit formula, and its presence leads to an anisotropic

Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
