We describe a hierarchical scheme for rapid adaptation of context dependent \skills". The underlying idea is to rst invest some learning eeort to specialize the learning system to become a rapid learner for a restricted range of contexts. This is achieved by constructing a \Meta-mapping" that replaces an slow and iterative context adaptation by a \one-shot adaptation", which is a context-depend...

Video-based human recognition at a distance remains a challenging problem for the fusion of multimodal biometrics. As compared to the approach based on match score level fusion, in this paper, we present a new approach that utilizes and integrates information from side face and gait at the feature level. The features of face and gait are obtained separately using principal component analysis (P...

A three-part strategy has been developed to study molecular interactions in biological systems at the atomic level. First, isotopically labeled carotenoids and retinoids are prepared by organic total synthetic schemes with labels at predetermined atomic positions and combinations of positions. Subsequently, the labeled compounds are incorporated in the biological system. Finally, the system is ...

Two groups describe unique methods to sensitively and quantitatively investigate protein-DNA interactions in vitro. A plethora of tools exists to probe protein-DNA interactions, each one with its own strengths and weaknesses. The sensitivity and specificity of the methods, however, are crucial considerations when attempting to draw quantitative conclusions about binding affinity. Two recent pap...

We propose statistically self-similar and rotation-invariant models for vector fields, study some of the more significant properties of these models, and suggest algorithms and methods for reconstructing vector fields from numerical observations, using the same notions of self-similarity and invariance that give rise to our stochastic models. We illustrate the efficacy of the proposed schemes b...

To store and transmit the large amount of image data necessary for Image-based Rendering (IBR), efficient coding schemes are required. This paper presents two different approaches which exploit three–dimensional scene geometry for multi-view compression. In texture-based coding, images are converted to view-dependent texture maps for compression. In model-aided predictive coding, scene geometry...

New π-conjugated unsymmetrical β-diketones were synthesized thanks to a modular synthetic approach involving in situ generated acylketenes through thermal degradation of 1,4-dioxin-2-ones. This method gave access family new chromophores featuring either an indoline or benzothiazole as electron-donating groups one side and various aromatic moieties the other side. After complexation with boron d...

Indium antimonide (InSb), a narrow band gap III-V semiconductor is a promising infrared-active material for various optoelectronic applications. Synthetic challenge of colloidal InSb nanocrystals (NCs) lies in the limited choice of precursors. Only a few successful synthetic schemes involving highly toxic stibine (SbH3) or air- and moisture-sensitive metal silylamides (In[N(Si-(Me)3)2]3 or Sb[N...
