This paper describes the synthesis and detailed characterization of a new set of magnetic surfactants containing lanthanide metal counterions. SQUID magnetometry has been used to elucidate the magnetic phase behaviour, and small-angle neutron scattering (SANS) provides evidence of micellar aggregation in aqueous media. This study also reveals that for cationic ...

We consider a closed Nutrient-Phytoplankton-Zooplankton (NPZ) model that allows for a delay in the nutrient recycling. A delay-dependent conservation law allows us to quantify the total biomass in the system. With this, we can investigate how a planktonic ecosystem is affected by the quantity of biomass it contains and by ...

Although reconsolidation opens up new avenues to erase excessive fear memory, subtle boundary conditions put constraints on retrieval-induced plasticity. Reconsolidation may only take place when memory reactivation involves an experience that engages new learning (prediction error). Thus far, it has not been possible to determine the optimal degree of novelty ...

Abstract A 3-year-old girl had global developmental delay with dysmorphic facies. In addition, she was found to have congenital hypothyroidism. In view of the associated dysmorphism, a karyotype analysis was done. It revealed a novel translocation mutation, 46XX t(1;14) (p22;q32). The association of this mutation with congenital hypothyroidism has been ...

The enzyme glutamate dehydrogenase (GDH) plays an important role in integrating mitochondrial metabolism of amino acids and ammonia. Glutamate may function as a respiratory substrate in the oxidative deamination direction of GDH, which also yields α-ketoglutarate. In the reductive amination direction GDH produces glutamate, which can then be used for ...

Age is one of the most robust correlates of criminal behavior. Yet, explanations for this relationship are varied and conflicting. Developmental theories point to a multitude of sociological, psychological, and biological changes that occur during adolescence and adulthood. One prominent criminological perspective outlined by Gottfredson and Hirschi claims that age ...

Nanostrcutured particles and polycrystalline thin films of Sn-doped chalcopyrite are synthesized by newly-developed methods. Surprisingly, Sn doping introduces a narrow partially filled intermediate band (IB) located ~1.7 eV (CuGaS(2)) and ~0.8 eV (CuInS(2)) above the valance band maximum in the forbidden band gap. Diffuse reflection spectra and photoluminescence spectra reveal extra absorption ...
