The total and causal ordering of group operations in distributed systems is at the core of solutions to many problems in distributed computing. Existing approaches are based on either a centralized coordinator to assign a sequence number for each operation or on a distributed two-phase protocol to determine the total ordering. This paper proposes a distributed single-phase protocol which determ...

All-trans-retinal and its condensation-products can cause retinal degeneration in a light-dependent manner and contribute to the pathogenesis of human macular diseases such as Stargardt’s disease and age-related macular degeneration. Although these toxic retinoid by-products originate from rod and cone photoreceptor cells, the contribution of each cell type to light-induced retinal degeneration...

Dynamic compaction is a soil improvement method which has been widely used for the increase of bearing capacity through stress wave propagation during heavy tamping. The cost and time of project implementation can be effectively curtailed by developing a model that can be used in the design of dynamic compaction operations. The numerical models offered so far are mostly one or two-dimensional, ...

The positive cones of the left orders on a free group can be described by their finite subsets. An algorithm is given for recognizing when a finite subset of a free group lies in a positive cone. This is used to show how one can construct a sequence of finite subsets of a positive cone whose union is the positive cone. Moreover, the method gives an overview of the positive cones of a free group...

Sensory systems must avoid saturation to encode a wide range of stimulus intensities. One way the retina accomplishes this is by using both dim-light-sensing rod and bright-light-sensing cone photoreceptor circuits. OFF cone bipolar cells are a key point in this process, as they receive both excitatory input from cones and inhibitory input from AII amacrine cells via the rod pathway. However, i...

We prove that the group of left self-distributivity, a cousin of Thompson’s group F and of Artin’s braid group B∞ that describes the geometry of the identity x(yz) = (xy)(xz), admits a bi-invariant linear ordering. To this end, we define a partial action of this group on finite binary trees that preserves a convenient linear ordering.

New insight into the superconducting properties of HgBa2CuO4 (Hg-1201) cuprates is provided by combined measurements electrical resistivity and single crystal X-ray diffraction under pressure. The changes induced increasing pressure up to 20 GPa in optimally doped crystals were investigated. as a function temperature show metallic behavior ~10 that gradually passes an insulating state, typical ...
