A global analysis of spin-flavour precession (SFP) solutions to the solar neutrino problem is given, taking into account the impact of the full set of latest solar neutrino data, including the recent SNO data and the 1496–day Super-Kamiokande data. These are characterized by three effective parameters: ∆m sol ≡ ∆m, the neutrino mixing angle θsol ≡ θ and the magnetic field parameter μB⊥. For the...

Shape from Polarization (SfP) estimates surface normals using photos captured at different polarizer rotations. Fundamentally, the SfP model assumes that light is reflected either diffusely or specularly. However, this model is not valid for many real-world surfaces exhibiting a mixture of diffuse and specular properties. To address this challenge, previous methods have used a sequential soluti...

We report here the development of a general strategy for site-specific labeling of proteins with small molecules by posttranslational modification enzyme, phosphopantetheinyl transferase Sfp. The target proteins are expressed as fusions to the peptide carrier protein (PCP) excised from nonribosomal peptide synthetase, and Sfp catalyzes the covalent modification of a specific serine residue on P...

The whole mol-ecule of the title compound, C17H10N4O5·2H2O, is generated by twofold rotation symmetry and it crystallized as a dihydrate. The planes of the phthalimide moieties and the urea unit are almost normal to one another, with a dihedral angle of 78.62 (9)°. In the crystal, mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds, forming a three-dimensional framework structure. The cryst...

N-hydroxyethyl phthalimide (PE-I) was prepared by refluxing phthalic anhydride with ethanolamine. 3phthalimidoethyl substituted benzoic acids (PE-II) were prepared by refluxing N-hydroxyethyl phthalimide with substituted benzoic acids. The corresponding acid chlorides (PE-III) were condensed with benzilidine-4acetophenone derivatives to afford the 3-(phthalimidoethyl)-4-substituted cinnamoyl su...

A series of aminoacetylenicoxyphthalimide namely N-[4-(t-amino)-2-butynyloxy] phthalimides were synthesized from the reaction of N-hydroxyphthalimide with propargyl bromide in sodium ethoxide to generate N-(2-butynyloxy)phthalimide. The desired compounds were prepared through Mannich reaction of N-(2-butynyloxy)phthalimide with formaldehyde, appropriate amine in peroxide-free dioxin and cuprous...

A simple and model-independent method is proposed to extract information on νe transition into antineutrinos via the spin flavor precession (SFP) from the measurements of solar neutrino flux at SNO and Super-Kamiokande. Incorporating the KamLAND experimental results, we examine how large the suppression of the solar neutrino flux could be due to the SFP mechanism in the context of the hybrid sc...

El uso creciente de las métricas de Puntos Función para la gestión de proyectos de software ha promovido el desarrollo de variantes del Análisis de Puntos Función para aproximar el tamaño funcional cuando la documentación, el tiempo o los recursos disponibles no permiten realizar el cálculo estándar. Scenario Function Points (SFP) es un procedimiento basado en el método IFPUG que permite estima...
