The manufacturing industry has at its disposal a number of processes for constructing objects, including gravity casting, injection molding, stereolithography, NC-machining, deformation, composition, and spray deposition. The survey by Bose and Toussaint [3, 5] gives an overview of geometric problems and algorithms arising in manufacturing processes. Castingis one of the manufacuring processes ...

Axion physics has received a boost with the recent claim of the PVLAS collaboration. Their results can be interpreted as due to a new axionlike particle but the CAST collaboration has not found trace of it. While the axionlike particle interpretation of the PVLAS signal is going to be probed by dedicated laboratory experiments, it is mandatory to find either alternatives to it or models in whic...

Interlocus gene conversion occurs such that a certain length of DNA fragment is non-reciprocally transferred (copied and pasted) between paralogous regions. To understand the rate and tract length of gene conversion, there are two major approaches. One is based on mutation-accumulation experiments, and the other uses natural DNA sequence variation. In this review, we overview the two major appr...

Although the boundary elements of the Drosophila Bithorax complex (BX-C) have properties similar to chromatin insulators, genetic substitution experiments have demonstrated that these elements do more than simply insulate adjacent cis-regulatory domains. Many BX-C boundaries lie between enhancers and their target promoter, and must modulate their activity to allow distal enhancers to communicat...

In this paper, we present a new wavelet-based compression algorithm for still color images especially for low bitrates. The coding algorithm distinguishes itself by a high adaptivity to the image content. It yields an embedded bitstream with the advantage of spatial and quality scalability. The performance of the wavelet codec is demonstrated in comparison with the JPEG standard for diierent co...

This Application Note describes an HPLC method to simultaneously separate and identify deoxygenated compounds from a guaiacol catalytic reaction to evaluate the conversion rate under varied reaction conditions, as part of the novel catalysis processes to obtain renewable biofuels from bioderived oils. The proposed methodology was applied to two different reaction batches, 13 samples were collec...
