Strange matrix elements of the nucleon are calculated within the light-cone formulation of the meson cloud model. The Q 2 dependence of the strange vector and axial vector form factors is computed, and the strangeness radius and magnetic moment extracted, both of which are found to be very small and slightly negative. Within the same framework one finds a small but non-zero excess of the antist...

Already in the past, hadronic τ decays have served as an interesting source to obtain information on the parameters of the Standard Model, like the strong coupling αs or the strange quark mass. Below it will be shown that the approach to obtain the strange mass from the hadronic τ-decay width can be turned into a determination of the CKM matrix element Vus, once the strange mass is used as an i...

The present comment focuses on the distinction between attachment as bond formation and expectations of availability and responsiveness (security) within attachment relationships. We enumerate key components of bonding and functions of carer secure base support. Our analysis has implications for design and suggests that robots are unlikely to serve effectively as sole carers. Even with robots a...

Abstract. We made a detailed study of the properties of the electron layer near the quark surface of strange stars with strong (∼ 10 − 10G) magnetic fields. The electrostatic potential and the electric field at the quark surface were calculated as functions of the magnetic field intensity of bare strange stars. Using an ultrastrong (B ≥ 2.5× 10G) magnetic field, we found that the distribution o...

There is at present a doubly discrete classification for strange attractors of low dimension, d(L)<3. A branched manifold describes the stretching and squeezing processes that generate the strange attractor, and a basis set of orbits describes the complete set of unstable periodic orbits in the attractor. To this we add a third discrete classification level. Strange attractors are organized by ...

Abstract. The properties of the layer of electrons near the quark surface of strange stars with strong (∼ 10 − 10G) magnetic field are studied in details. The electrostatic potential and the electric field at quark surface are calculated as functions of magnetic field intensity for bare strange stars. We find with ultra-strong (B ≥ 2.5 × 10G) magnetic field, the distribution of electrons, which...

In this paper we deal with the minimization of a convex function over the solution set of a range inclusion problem determined by a multivalued operator with convex graph. We attach a dual problem to it, provide regularity conditions guaranteeing strong duality and derive for the resulting primal-dual pair necessary and sufficient optimality conditions. We also discuss the existence of optimal ...
