Organogels (hydrophobic polymer gels) are soft materials based on polymeric networks swollen in organic solvents. They hydrophobic and possess a high content of solvent low surface adhesion, rendering them interesting applications such as encapsulants, drug delivery, actuators, slippery surfaces (self-cleaning, anti-waxing, anti-bacterial), or for oil-water separation. To design functional orga...

Juxtacrine signaling is an important class of signaling systems that plays a crucial role in various developmental processes ranging from coordination of differentiation between neighboring cells to guiding axon growth during neurogenesis. Such signaling systems rely on the interaction between receptors on one cell and trans-membrane ligands on the membrane of a neighboring cell. Like other sig...

This paper presents a linear multiplier that can be fully implemented in CMOS technology. The circuit implements the function of mathematical multiplication for the two input signals. Since this multiplier is not a conventional mixer, some unconventional methods were use, such as, to realize the function of multiplication, a translinear loop is implemented, which is based on the exponential rel...

We identify a class of monomial supports that are inherently improper because any surface rational parametrization defined on them is improper. A surface support is inherently improper if and only if the gcd of the normalized areas of the triangular sub-supports is non-unity. The constructive proof of this claim can be used to detect all and correct almost all improper surface parametrizations ...

Computational tractability has been a major concern in the area of termi-nological knowledge representation and reasoning. However, all analyses of the computational complexity of terminological reasoning are based on the hidden assumption that subsumption in terminologies reduces to subsumption of concept descriptions without a signiicant increase in computational complexity. In this paper it ...

Stochastic Diffusion Search is an efficient probabilistic bestfit search technique, capable of transformation invariant pattern matching. Although inherently parallel in operation it is difficult to implement efficiently in hardware as it requires full inter-agent connectivity. This paper describes a lattice implementation, which, while qualitatively retaining the properties of the original alg...

We prove that an inherently nonfinitely based algebra cannot generate an abelian variety. On the other hand, we show by example that it is possible for an inherently nonfinitely based algebra to generate a strongly solvable variety.
