Computer-aided design and manufacturing feasibility of a large-scale collagen protein model for educational use
… collagen model was modeled with the SolidWorks and Catia software packages. One chain of space-filled Collagen 1CGD was modeled with SolidWorks, and the entirety of space-filled Collagen 1BKV and 1CGD was modeled with Catia. The feasibility of manufacturing the model with rigid molds was …

Electronic Structure of Three Center Two Electron Bonds in Boron Rich Materials: A Study of Molecules, Crystals, and Amorphous Solids using the ab initio Orthogonalized Linear Combination of Atomic Orbitals Method
It has been shown that isomers of carborane, α and β rhombohedral boron, α and β tetragonal boron, γ boron, and boron carbide tend to form icosahedral structures. If the icosahedra were formed with pure boron, it has been demonstrated that there is an insufficient number of electrons to populate …

Investigating mechanisms of biophysical diversity between phasic and tonic motor neurons
… core neuronal properties (intrinsic biophysical and synaptic properties), which are the building blocks of brain function and computation. Despite the central role of these properties in brain function, the underlying molecular and biophysical mechanisms which generate this diversity remain …

Structural complexity and its implications for design of cyber-physical systems
… systems are becoming more complex as we demand more performance and better lifecycle properties (e.g. robustness) from them. As a consequence system development projects are becoming increasingly challenging and are falling behind in terms of schedule and cost performance. The complexity of …

DEVELOPMENT OF ALGORITHMS FOR CLASSICAL AND SEMICLASSICAL DYNAMICS
… this research introduces novel concepts and algorithms aimed at discerning whether or not a molecule is composed of a collection of approximately independent vibrating fragments. Specifically, from a time-dependent perspective, the uncorrelated degrees of freedom must obey Liouville …

Use of Multiple Representations to Explore Students’ Understandings of Covalent and Ionic Bonding as Measured by the Bonding Representations Inventory
… as some students struggle to identify the ionic and covalent nature of bonds within a variety of compounds. The topic is formally introduced in both middle school and secondary education (grades 6-12) and reintroduced in the undergraduate general chemistry curriculum. Teachers use multiple …
