An important open problem in molecular biology is how to use computational methods to understand the structure and function of proteins given only their primary sequences. We describe and evaluate an original machine-learning approach to classifying protein sequences according to their structural folding class. Our work is novel in several respects: we use a set of protein classes that previous...

A new method for the preparation of graphene has been developed via porphyrin exfoliation of graphite in NMP. The exfoliation, which follows the intercalation of organic ammonium ions, is based on the pi-pi interaction between graphene and porphyrins. The graphene sheets prepared by this method show undisturbed sp(2) carbon networks.

An important aspect of auditory scene analysis is sequential grouping of sounds that are similar to one another in preference to sounds that follow one another. This grouping problem is captured by stream segregation tasks with alternating distinct sounds. We examined human auditory cortex activity with low noise fMRI in a stream segregation experiment relying on timbre differences of alternati...

Marker-based image segmentation has been widely used in image analysis and understanding. The well-known Meyer’s marker-based watershed algorithm by immersion is realized using the hierarchical circular queues. A new marker-based segmentation algorithm relying on disjoint set union is proposed in this paper. It consists of three steps, namely: pixel sorting, set union, and pixel resolving. The ...

A popular technique of designing multiple-input multiple-output (MIMO) communication systems relies on optimizing the positive semidefinite covariance matrix at source. In this paper, a unified MIMO optimization framework based Karush-Kuhn-Tucker (KKT) conditions is proposed. framework, with aid theory, <xref ref-type="theorem" rid="theorem1" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns...

Parallel Ireatment of syntactic considerations in generation promises quality and speed. Parallelism should be used not only for simultaneous processing of several sub-parts of the output, but even within single parts. If beth types of parallelism are used with incremental generation it becomes unnecessary to build up and manipulate representations of sentence structure-the syntactic form of th...

In this work we integrate an electronic nose with a mobile robot for the purpose of detecting odor leaks in a 1-dimensional environment. The robot relies on two mechanisms, the navigational algorithms to manoeuver in the environment and its sensing mechanism to adequately represent odors and their intensities. The emphasis of the proposed odor tracking strategy is placed on the cooperation betw...
