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 ...

OBJECTIVE US Food and Drug Administration (FDA) warnings recommend monitoring negative symptoms associated with the initiation of antidepressant medications as these symptoms may interfere with full recovery and pose safety concerns. There is currently no brief, reliable rating instrument for assessing treatment-emergent, negative symptoms. We evaluated the psychometric properties of 2 versions...

This paper aims at shedding a new light on the novelty of Poincaré’s Méthodes nouvelles de la mécanique céleste. The latter’s approach to the three-body-problem has often been celebrated as a starting point of chaos theory in relation to the investigation of dynamical systems. Yet, the novelty of Poincaré’s strategy can also be analyzed as having been cast out some specific algebraic practices ...

We have previously shown (Sunkara et al., 1989; Taylor et al., 1991) that 6-o-butanoyl castanospermine (BuCast) was a 30-50-fold better inhibitor of HIV syncytia formation than castanospermine (Cast). Radiolabeled Cast and BuCast were used to study the uptake and metabolism of these compounds in cultured cells and in mice. BuCast was preferentially taken up by cells compared to Cast. Approximat...

Drosophila larvae exhibit klinotaxis when placed in a gradient of temperature, chemicals, or light. The larva samples environmental stimuli by casting its head from side to side. By comparing the results of two consecutive samples, it decides the direction of movement, appearing as a turn proceeded by one or more head casts. Here by analyzing larval behavior in a light-spot-based phototaxis ass...

Myostatin (MSTN) is an inhibitor of skeletal muscle growth, and a mutation in the gene coding region leads to increased muscling. Calpastatin (CAST) is a specific inhibitor of the ubiquitous calcium-dependent proteases, µ-calpain and m-calpain, found in mammalian tissues. In this study, genomic DNA was extracted from Zandi sheep blood samples. Gel monitoring and spectrophotometer methods were u...

we study algebraic properties of categories of merotopic, nearness, and filter algebras. we show that the category of filter torsion free abelian groups is an epireflective subcategory of the category of filter abelian groups. the forgetful functor from the category of filter rings to filter monoids is essentially algebraic and the forgetful functor from the category of filter groups to the cat...

This paper presents an algebraic theory of linear signal processing. At the core of algebraic signal processing is the concept of a linear signal model defined as a triple (A,M,Φ), where familiar concepts like the filter space and the signal space are cast as an algebra A and a module M, respectively, and Φ generalizes the concept of the z-transform to bijective linear mappings from a vector sp...

occur in information theory [1], and regularization [2], respectively. Given such expressions, we are interested in the automatic generation of code that is at least as fast and as numerically stable as what an expert would produce. Conceptually, the problem is similar to how compilers cast scalar expressions in terms of the available instruction set. The corresponding problem for linear algebr...
