In this paper, we provide a method to accelerate the power of splicing systems. We introduce the splicing systems on trees to be built as partially annealed single strands, that is a quite similar notion and a natural extension of splicing systems on strings. Trees are a common and useful data structure in computer science and have a biological counterpart such as molecular sequences with secon...

We give a general procedure to construct a certain class of ”quandle-like” structures from an arbitrary group. These structures, which we refer to as pseudoquandles, possess two of the three defining properties of quandles. We classify all pseudoquandles obtained from an arbitrary finitely generated abelian group. We also define the notion of the kernel of an element of a pseudoquandle and prov...

We present a method for generating scales and scale-like structures on a polygonal mesh through surface replacement. As input, we require a triangular mesh that will be covered with scales and one or more proxy-models to be used as the scale’s shape. A user begins scale generation by drawing a lateral line on the model to control the distribution and orientation of scales on the surface. We the...

All vertebrate brains have a cerebellum, and most of them have one or more additional structures that are histologically similar to the cerebellum. The cerebellum-like structures include the medial octavolateral nucleus in most aquatic vertebrates; the dorsal octavolateral nucleus in many aquatic vertebrates with an electrosensory system; the marginal layer of the optic tectum in ray-finned fis...

1 Abstract The CubeSat community has been a research platform for the simplification and miniaturization of scientific instrumentation. Although the instrumentation has been developing rapidly within the last few years, the means of deploying said instruments have been lacking. Presented is a means of deploying a scientific instrument based on the use of scissor-boom technology, which has gover...

After a worker was found fatally pinned between the top rail of scissor lift and an overhead beam, rescue attempts were frustrated by unresponsive controls. In investigation this fatal accident, certain controls did not function or functioned intermittently. The intermittent nature malfunction indicated that evidence sensitive — likely to be disturbed if device disassembled using typical destru...

In this paper we analyze O’Hara’s partition bijection. We present three type of results. First, we see that O’Hara’s bijection can be viewed geometrically as a certain scissor congruence type result. Second, we present a number of new complexity bounds, proving that O’Hara’s bijection is efficient in most cases and mildly exponential in general. Finally, we see that for identities with finite s...
