Current state of the art within textile truss structures requires a variety of production, assembly and joining processes to conclude in a fully integrated truss configuration. This approach sees the joining and bonding of separate struts to node parts. The node is the connecting area which accommodates the strut-to-strut intersections. A production process of separate truss components (struts and nodes) inherently has constraints, such as increased labour, bonding issues and longevity of product. In the development of a fully integrated textile truss, the utilisation of conventional weaving technology and production principles allowed the development of the three-dimensional woven nodal truss structure. The three-dimensional woven nodal truss structure’s node and nodal segmentation, defined by boundary lines provided defined areas within the weaving width, length and depth for the assignment of weave architectures. The commonalities within the production of varying strut-to-strut intersections and strut-to-strut variable dimensions within a T-shaped and K-shaped nodal configuration provide the foundations for the development of elementary nodes for other three-dimensional woven nodal truss structures. The development of the generic procedure and application of the three-dimensional-to-two-dimensional-to-three-dimensional nodal structure production process and elementary nodes will be presented within this article.

This paper is an introduction to behavioral genetics for researchers and practioners in language development and disorders. The specific aims are to illustrate some essential concepts and to show how behavioral genetic research can be applied to the language sciences. Past genetic research on language-related traits has tended to focus on simple etiology (i.e., the heritability or familiality of language skills). The current state of the art, however, suggests that great promise lies in addressing more complex questions through behavioral genetic paradigms. In terms of future goals it is suggested that: (a) more behavioral genetic work of all types should be done—including replications and expansions of preliminary studies already in print; (b) work should focus on fine-grained, theory-based phenotypes with research designs that can address complex questions in language development; and (c) work in this area should utilize a variety of samples and methods (e.g., twin and family samples, heritability and segregation analyses, linkage and association tests, etc.).

Many Body Perturbation Theory

Two-dimensional boron is promising as a tunable monolayer metal for nano-optoelectronics. We study the optoelectronic properties of two likely allotropes of two-dimensional boron using first-principles density functional theory and many-body perturbation theory. We find that both systems are anisotropic metals, with strong energy- and thickness-dependent optical transparency and a weak (<1%) absorbance in the visible range. Additionally, using state-of-the-art methods for the description of the electron-phonon and electron-electron interactions, we show that the electrical conductivity is limited by electron-phonon interactions. Our results indicate that both structures are suitable as a transparent electrode.

Mathematical Literature

We survey the mathematical literature on umbral calculus (otherwise known as the calculus of finite differences) from its roots in the 19th century (and earlier) as a set of “magic rules” for lowering and raising indices, through its rebirth in the 1970’s as Rota’s school set it on a firm logical foundation using operator methods, to the current state of the art with numerous generalizations and applications. The survey itself is complemented by a fairly complete bibliography (over 500 references) which we expect to update regularly.

Water Impoundment

The state-of-the-art of surface water impoundment modeling is examined from the viewpoints of both hydrodynamics and water quality. In the area of hydrodynamics current one dimensional integral energy and two dimensional models are discussed. In the area of water quality, the formulations used for various parameters are presented with a range of values for the associated rate coefficients.
