We present results for a galaxy formation model that includes a simple treatment for the disruption of dwarf galaxies by gravitational forces and galaxy encounters within galaxy clusters. This is implemented a posteriori in a semi-analytic model by considering the stability of cluster dark matter subhaloes at z = 0. We assume that a galaxy whose dark matter substructure has been disrupted will ...

A general approach was developed to quantify hydroxycinnamic acid derivatives and the glycosides of flavonols and flavones using UV molar relative response factors (MRRFs). More than 90 standards were analyzed by LC-MS and divided into five groups based on the λ(max) of their band I absorbance profiles. For each group, a commercially available standard was chosen as the group reference standard...

This is implemented a posteriori in a semi–analytic model by considering the stability of cluster dark matter sub-haloes at z = 0.

development of a suitable method for color sorting of agricultural products such as: tomato, apple and orange, based on surface reflection and image formation was the goal of this research. a suitable scheme of color differentiation using an optic head and electrical processing circuitry for separating red from green and other colors is presented. a photo-conductive transducer, electrical resis...

Far-red emitting fluorescent dyes for optical microscopy, stimulated emission depletion (STED), and ground-state depletion (GSDIM) super-resolution microscopy are presented. Fluorinated silicon-rhodamines (SiRF dyes) and phosphorylated oxazines have absorption and emission maxima at about λ≈660 and 680 nm, respectively, possess high photostability, and large fluorescence quantum yields in water...

We report spectra obtained with the Spitzer Space Telescope in the λ = 5 – 35 μm range of HD 233517, an evolved K2 III giant with circumstellar dust. For λ > 13 μm, the flux is a smooth continuum that varies approximately as ν. For λ < 13 μm, although the star is oxygen-rich, PAH features produced by carbon-rich species at 6.3 μm, 8.2 μm, 11.3 μm and 12.7 μm are detected along with likely broad...

The linear-algebraic λ -calculus and the algebraic λ -calculus are untyped λ -calculi extended with arbitrary linear combinations of terms. The former presents the axioms of linear algebra in the form of a rewrite system, while the latter uses equalities. When given by rewrites, algebraic λ -calculi are not confluent unless further restrictions are added. We provide a type system for the linear...

Conventional techniques for combating phishing have focused primarily on detecting phishing web sites and preventing users from revealing their passwords to such sites. This passive form of defense is by its nature incomplete and does nothing to protect users that do reveal their passwords. Combating the phishing threat requires more than simple avoidance—it requires a more active approach to d...
