Solution structure of a novel α-conotoxin with a distinctive loop spacing pattern
Amino Acids, 2011α-Pharmacological conotoxins are among the most selective ligands of nicotinic acetylcholine receptors with typical cysteine frameworks. They are characterized by the intercysteine loop and classified into various subfamilies, such as α3/5 and α4/7 conotoxins.

PLANAR PATTERNS WITH FIVEFOLD SYMMETRY AS SECTIONS OF PERIODIC STRUCTURES IN 4-SPACE
International Journal of Modern Physics B, 1990Two quasiperiodic planar patterns with fivefold symmetry are derived from the root lattice A4 in 4-space. A detailed analysis of the geometry of the A4 Voronoi complex and its dual complex is presented with special emphasis on fivefold symmetry. By means of the general dualization method, 2D patterns are obtained, one with triangular tiles and a ...

Surface and structural studies in a PbCrO4 Liesegang pattern with revert spacing
Chemical Physics Letters, 2019Abstract We present a novel study of a PbCrO4 Liesegang pattern exhibiting revert spacing. Scanning Electron Microscopy (SEM), Atomic Absorption Spectrometry (AAS) and Energy Dispersive X-ray (EDX) spectroscopy measurements are carried out, and are shown to support the adsorption of CrO 4 2 - on the precipitate, which becomes more ...

Generating flat patterns for folded structures: Search space reduction
Packaging Technology and Science, 2017A significant number of packaging products can be represented as folded structures. This contribution demonstrates an approach for generating a set of feasible flat patterns based upon a graph representation of the folded structures. It presents algorithms to detect several typical design features.

Real Space Structure and Scattering Patterns of Model Polymer Nanocomposites
Macromolecules, 2007Microscopic polymer liquid state theory is employed to study the real space pair correlation functions and collective scattering structure factors of melt polymer nanocomposites composed of hard spheres and adsorbing homopolymers over length scales ranging from monomeric to macroscopic.

HCI Design Patterns for PDA Running Space Structured Applications
2007Nowadays, mobile activities such as m-commerce, m-learning, etc, are being increasingly adopted by people. Information availability will be a key feature in future applications. Public spaces, as shops, libraries, museums, etc do not have enough information available to visitors, mainly due to physical space constraints. In this context, PDAs provide a

Analysing highly complex and highly structured point patterns in space
Spatial Statistics, 2017Abstract The purpose of this paper is to discuss two recently introduced approaches that focus on structures of different events that occur randomly in space: spatial dependence graph models (SDGMs), and network intensity functions. While SDGMs are undirected graphical models which capture the conditional independence structure between components of ...

Behavior Pattern Extraction Based on Growing Neural Networks for Informationally Structured Space
2015 IEEE Symposium Series on Computational Intelligence, 2015In this paper, we focus on behavior pattern extraction using sensor networks and portable sensing system. Behavior analysis is one of the most important tasks, which provides suitable information service to users. This paper proposes a pattern extraction method based on growing neural networks. The learning system is composed of two modules for feature

Folding patterns of planar gossamer space structures consisting of membranes and booms
Acta Astronautica, 2014Abstract The combination of large membranes and light-weight deployable booms, often called a gossamer structure, has enabled innovative space missions, such as solar sailing, to become possible. Though many designs have been proposed and demonstrated, two problems remain regarding the folding patterns of the membranes.

Composite pattern structured light projection for human computer interaction in space
SPIE Proceedings, 2005Interacting with computer technology while wearing a space suit is difficult at best. We present a sensor that can interpret body gestures in 3-Dimensions. Having the depth dimension allows simple thresholding to isolate the hands as well as use their positioning and orientation as input controls to digital devices such as computers and/or robotic ...
