Repeated spike patterns have often been taken as evidence for the synfire chain, a phenomenon that a stable spike synchrony propagates through a feedforward network. Inter-spike intervals which represent a repeated spike pattern are influenced by the propagation speed of a spike packet. However, the relation between the propagation speed and network structure is not well understood. While it is...

Many types of active matter, such as biological cells, have liquid-crystalline membranes, which are soft and flexible in their interactions with their surroundings and sometimes allow molecular-structural or -orientational changes to extend for long distances, owing to long-range molecular interactions. Despite the technological and fundamental importance of these long-range changes, there is n...

We have created a radial basis function network that allocates a new computational unit whenever an unusual pattern is presented to the network. The network learns by allocating new units and adjusting the parameters of existing units. If the network performs poorly on a presented pattern, then a new unit is allocated which memorizes the response to the presented pattern. If the network perform...

This paper presents the results of an experimental study axial capacity circular spirally-reinforced concrete columns that were subjected to accelerated corrosion while sustaining a constant compressive service load. Two sets five each designed with different spiral pitch investigate effect confinement on propagation. Columns non-confining reinforcement had only their longitudinal reinforcing s...

We review propagation patterns for describing object-oriented software at a higher level of abstraction than the one used by today's programming languages. A propagation pattern deenes a family of programs from which we can select a member by giving a class dictionary graph which details the structure of behavior through part-of and inheritance relationships between classes. The paper introduce...

ABSTRACT: In this paper we present moment invariant and neural network to classify airport pavement distress images. The moment invariant has been extracting images feature that published two-dimensional pattern recognition application method in 1962. The image pattern can be reduced to number of values such that they are description of the translation, scale, and rotation of an object in the i...

Corticotomy is an essential procedure for deformity correction and there are many techniques described. However there is no proper classification of the fracture pattern resulting from corticotomies to enable any studies to be conducted. We performed a retrospective study of corticotomy fracture patterns in 44 patients (34 tibias and 10 femurs) performed for various indications. We identified f...

We report on the use of a novel phase element to control the far-field intensity pattern generated by a high-peakpower, femtosecond laser. The pre-determined intensity pattern results in a well defined location of the filaments formed by the propagation of these beams through the atmosphere. This enhancement of the localization and repeatability of the intensity distribution can be extremely be...

The propagation of the soliton pattern through optical fiber with weakly disordered dispersion coefficient is considered. Solitons perturbed by this disorder radiate and, as a consequence, decay. The average radiation profile is found. Emergence of a long-range intrachannel interaction between the solitons (mediated by this radiation) is reported. We show that soliton in a multisoliton pattern ...

a-Synuclein (a-syn) aggregation is central to neuropathological changes in Parkinson’s disease. The aggregates spread within the central nervous system according to a very predictable pattern. A prion-like transmission of a-syn aggregates has been recently proposed to explain this propagation pattern. First, we review the growing evidence for such a mechanism. This process is likely to occur in...
