The electron spin polarization (ESP) at surfaces of bulk and thin film ferromagnetic materials has been investigated using electron capture spectroscopy (ECS), which probes the ESP of the topmost surface layer. At surfaces of PtMnSb, Tb and Fe,,B,,, we find nonhero ESP due to long-ranged or short-ranged ferromagnetic order. The sign of the ESP at surfaces of the Heusler alloy PtMnSb is in agree...

The availability of domain-specific knowledge models in various forms has led to the development of several tools and applications specialized on complex domains such as bio-medecine, tourism and chemistry. Yet, most of the current approaches to the extraction of domain-specific knowledge from text are limited in their portability to other domains and languages. In this paper, we present and ev...

An unsupervised application for the visual analysis of metallic substrates and paint coatings is presented. Model based classification is used for the analysis of metallic substrates while a segmentation of the image is required to distinguish between paint and substrate or between paint and rust for the analysis of paint coatings. A unified framework based on the Expectation−Maximization (EM) ...

The estimation of rare K decay matrix-elements from Kl3 experimental data is extended beyond LO in Chiral Perturbation Theory. Isospin-breaking effects at NLO (and partially NNLO) in the ChPT expansion, as well as QED radiative corrections, are now accounted for. The analysis relies mainly on the cleanness of two specific ratios of form-factors, for which the theoretical control is excellent. A...

Renewable energy sources like solar and fuel cells are emerging as a promising supplementary power sources due to their merits of cleanness, high efficiency, and high reliability. But the output levels of these are low. An isolated bidirectional full-bridge dc–dc converter can be used for interfacing battery to the system. Because of the presence of leakage inductance of the isolation transform...

A ring R is called strongly clean if every element of R is the sum of a unit and an idempotent that commute with each other. A recent result of Borooah, Diesl and Dorsey [3] completely characterized the commutative local rings R for which Mn(R) is strongly clean. For a general local ring R and n > 1, however, it is unknown when the matrix ring Mn(R) is strongly clean. Here we completely determi...

Sphingoid base derivatives have attracted increasing attention as promising chemotherapeutic candidates against lifestyle diseases such as diabetes and cancer. Natural sphingoid bases can be a potential resource instead of those derived by time-consuming total organic synthesis. In particular, glucosylceramides (GlcCers) in food plants are enriched sources of sphingoid bases, differing from tho...

We provide a self-contained convergence proof in this section. The skeleton of our convergence proof follow closely from Lacoste-Julien et al. (2013) and Jaggi (2013). There are a few subtle modification and improvements that we need to add due to our weaker definition of approximate oracle call that is nearly correct only in expectation. The delayed convergence is new and interesting for the b...
