Strong Magnetic Field Effects and Molecular Processes with Applications to White Dwarfs
<p>Radiative transitions of hydrogenlike atoms in external magnetic fields of strength applicable to magnetic white dwarfs, i.e. B < 10<sup>3</sup> megagauss, have been investigated for field-free principal quantum numbers n < 6. Finite proton mass corrections are included. Relativistic corrections …

Theoretical study of the molecular processes occurring during the growth of Silicon on Si(100) and SixGe1-x/Si(100)
… to elucidate the mechanisms of several surface processes. The focus of this work was on the processes occurring on the surface of pure, strained silicon(100)-2??1 as well as silicon-germanium during the growth of silicon by gas-source molecular beam epitaxy (GSMBE). First-principles calculations …

Transcriptional response to spatial learning and foraging in honey bees: molecular bases for adult neuroplasticity
… goal of neuroscience research is to discover molecular processes that enable persistent neuroplasticity in the adult and aging brain. In many species, some types of neuroplasticity typically decrease with age. Honey bees and other social hymenopterans, however, exhibit a reinstatement of …

A framework for teaching biology using StarLogo TNG : from DNA to evolution
… students can see how small-scale changes in molecular processes can create large-scale changes in entire populations. In addition, the curriculum encourages students to engage in problembased learning, by which they are trained to approach questions creatively and independently.

Characterization of Hemocytes in Amblyomma americanum and Investigation of TRAF6’s Role in Proliferation of Hemocytes in Response to Infection
… in the southeast United States. Cellular and molecular aspects of the immune system of this species were examined. To investigate cellular processes, hemocytes produced in response to gram-negative infection were characterized according to their ultrastructure. Four hemocyte types were …

Using light to control and investigate cell biology
… to be a powerful tool for the interrogation of molecular and cellular biology. Beyond its use in microscopic applications, light has emerged as an attractive modulator of cellular function. Within the last two decades, scientists have begun to harness the power of light and light-sensitive …

Scaling of unitary synaptic strength in the context of network dynamics
… connection between two cells, and what meta-processes such mechanisms answer to. This question can be asked either mechanistically, by characterizing the molecular processes that regulate the synapse's transmission, or ontologically, by considering the impact of this transmission from the …

Computational Studies of the Concealed Gating Pathways and Electrophysiological Function of the Human Cardiac IKs Channel
… completion of the human genome, relating protein molecular structure to its physiological function remains a challenge for the next decade and beyond. Protein malfunction underlies many debilitating and life-threatening diseases. A framework relating protein structure-to-function is necessary for …

Internal Excitations of Stored Triatomic Hydrogen Molecular Ions
The triatomic hydrogen molecular ion H3+ is the simplest polyatomic molecule, besides its fundamental importance for quantum chemistry, it is one of the cornerstones of molecular processes in interstellar clouds. The dissociative electron recombination (DR) of H3+ is much studied, but still subject …

Mitochondrial dysfunction during ischaemia reperfusion injury in models of organ transplantation
… Upon reperfusion with oxygenated blood, molecular processes within mitochondria lead to the generation of reactive oxygen species (ROS), which damage the organelles and lead to cell death and ultimately tissue fibrosis. During organ transplantation, the organs are cut off the blood supply …

Photoacoustic Tomography of Diabetes and Reporter Genes
… it particularly well suited for functional and molecular studies. When using visible wavelengths, only a small number of naturally occurring absorbers, namely hemoglobin and melanin, give useful contrast in PAT. However, hemoglobin, as a contrast agent, can yield useful information about …

Investigating the evolution of diversity and complexity of Prokaryotic gene regulatory networks using in silico models
… heterogeneity and the role of stochastic molecular processes in gene regulatory network evolution are investigated. It is shown that: i) Repression is essential, even in constant environments, due to energetic constraints. ii) Stochastic basal gene expression forces shrinkage of genomes, …
