In finite element lore the term “unstable discretization” is often applied to situations when approximate solutions develop unphysical “wiggles”, or otherwise behave in a strange manner. A textbook example of such wiggles are Galerkin solutions of a scalar hyperbolic equation with discontinuous data. A more subtle example of instability is the “strange” behavior of mixed finite elements for the...

Two thousand questionnaires were distributed randomly via the Kennel Club (UK) to owners of purebred English Cocker Spaniels (ECSs). Owners were asked to give details about the ECSs they owned: age, sex, neuter status, coat colour. They were also asked to indicate whether their dog showed aggression (on a l-5 scale; 1, never or almost never, 5, always or almost always) in any of 13 situations. ...

This study examined associations between mother-infant nighttime interactions and mother-infant attachment when infants were 12 months old. Forty-four mother-infant pairs participated in this study. For three consecutive nights at home, babies were observed in their cribs using a digital video system. Mothers reported on their nighttime interactions with their babies using a self-report diary a...

The role of hadronization mechanism in polarization phenomena in semi inclusive deep inelastic scattering (SIDIS) and a purity method for extraction of polarized distribution functions are discussed. According to the Monte Carlo (MC) event generator, on which this method is based, hadrons can be produced via quark (diquark) fragmentation or light cluster decays. In contrast, the purity method a...

Abstract The strange vector form factors are evaluated for Q2 = 0 and Q2 = 1 GeV in the framework of the SU(3) chiral quark-soliton model (or semi-bosonized SU(3) Nambu-Jona-Lasinio model). The rotational 1/Nc and ms corrections are taken into account up to linear order. The mean-square strange radius 〈r2〉Sachs s = −0.35 fm and the strange magnetic moment μs = −0.44 μN are obtained. The results...

The strange magnetic moment of the nucleon (µ s) is examined as part of the nucleon's isoscalar anomalous moment. The dominant up and down quark effects in the anomalous moment may actually tend to favor µ s > 0, which is contrary to the negative values that generally result from model calculations. The possible origins of this apparent discrepancy are considered. Several years ago, Kaplan and ...

Motivated by trying to understand the absence of spectral lines in the thermal components of the X-ray compact sources observed recently by Chandra or XMM, we propose that these sources could be simply bare strange stars. The formation, cooling, and thermal photon radiation of bare strange stars have been investigated. It is suggested that thermal featureless spectrum could be a new probe for i...

ASTRONOMY AND ASTROPHYSICS The birth of strange stars and their dynamo-originated magnetic fields Abstract. It is shown that protostrange stars (PSSs) can be convective and that there are two possible scenarios describing their turbulence. Besides the local turbulence on the scale which is less than the mean free path of neu-trinos, large-scale (∼ 1 km) convection also may occur with properties...
