Exploring the determinants of chloride homeostasis in neurons using biophysical models
… be important in Cl- homeostasis. Here I present biophysical models of Cl- homeostasis using the pump-leak formulation. By means of numerical and novel analytic solutions, I demonstrate that the Na+/K+-ATPase, ion conductances, impermeant anions, electrodiffusion, water fluxes and cation-chloride …

Large-scale neural recordings and biophysical models for inferring network mechanisms of ketamine anesthesia
Ketamine is an NMDA receptor antagonist with powerful anesthetic, antidepressant, and psychotomimetic effects. At all therapeutic doses, ketamine generates robust gamma oscillations between 30-80 Hz that are typical of active, structured cognition; yet, under ketamine, gamma oscillations persist …

Linking biophysical models and life cycle assessment to evaluate environmental tradeoffs of urban water infrastructure design
… policy. Although integrated urban water models started by expanding on simple physical urban drainage models, they are now incorporating mechanisms for environmental change, social agents, and economic feedback. Although originally built to protect public health and the local aquatic …

Inactivation synergy between high energy neutrons and ⁶⁰Co gamma rays
… in "negative" repair. The validity of proposed biophysical models was tested using meristematic cells, as the response of these cells show an apparent absence of intertrack damage. Contrary to expectations, synergistic interaction was observed for both growth delay measurements and micronuclear …

Measuring and Forecasting Environmental Conditions From the Perspective of Rocky Intertidal Organisms
… determined by tides, waves, and weather. Models that incorporate these parameters can be used to predict and understand the distributions of organisms on both local and latitudinal scales. Intertidal organisms oscillate between marine and terrestrial conditions, a phenomenon controlled by …

High-Throughput Mapping of The Biological Effects of Particle Therapy
… to photons. It is essential to employ accurate biophysical models for particle beams in order to maximize the therapeutic potential of particle therapy through the introduction of biologically optimized treatment planning. The development of such models requires the support of large amounts of …

Quantitative Fluorescence Studies in Living Cells: Extending Fluorescence Fluctuation Spectroscopy to Peripheral Membrane Proteins
… and cell growth/regulation. Building accurate biophysical models of these processes requires quantitative characterization of the behavior of peripheral membrane proteins, yet methods to quantify their interactions inside living cells are very limited. Because peripheral membrane proteins …

Rapid diffusion in the brain extracellular space - biophysical constraints and physiological implications
Physiological experiments backed by biophysical models have shown that, in central glutamatergic synapses, changes in extracellular diffusivity or glutamate transporter functions exert significant influences on the excitatory transmission. Failures of transporter functions have also been related to …

Keeping it cool: mammal responses to microclimatic variation in disturbed Indonesian lowland forest.
… field data and observations with mechanistic models of microclimate and biophysical models of animal bioenergetics to determine the impacts of forest edges and microclimate variation on mammals at a site of disturbed forest in the Sikundur region of Sumatra, Indonesia. First, I identify …

Biophysical Model of Retraction Motor Neurons and Their Modification by Operant Conditioning
… modeling, this study examined OC-induced biophysical changes in B6 and B9. Neuron B4 makes an inhibitory chemical synaptic connection and is electrically coupled to B3, B6, and B9 retraction motor neurons. B4 excitability is reduced following OC. Neuron B51 is electrically coupled to B3, …

MODELLING THE INTERACTION BETWEEN WILD AND CULTIVATED SPECIES.
… aim of this thesis was the development of new models for the simulation of the interaction between cultivated and wild species. Biophysical models are powerful tools to analyze the interactions between plants and environmental variables as well as to optimize crop management. However, one of …

Disentangling how climate change and forest management alter fuels and fire regimes in Sierra Nevada forests
… in the face of those changes.Simulation models provide a tool for projecting how climate change will influence future fire regimes, the extent to which shifting fire regimes will release carbon to the atmosphere, and when and where we can mitigate these changes through fuel treatments. …

Assessing Impacts of Winter-hay Feeding on Soil and Forage Nutrient Dynamics in a Rotationally-Grazed Pasture System in Arkansas
… (i.e., vegetation indices) and forage biophysical variables. Imagery from multiple sensors at varied spatial resolution revealed strong positive correlation (P < 0.001) among satellite, UAV, and a handheld crop sensor. Forage biophysical variables, DFY, as well as percent forage N and …
