Band structures of cylindrical AlN/GaN quantum dots with fully coupled piezoelectric models
(2010-12-31)We study the coupled electro-mechanical effects in the band structure calculations of low dimensional semiconductor nanostructures (LDSNs) such as AlN/GaN quantum dots. Some effects in these systems are essentially nonlinear. ... -
Band structures of laterally coupled quantum dots, accounting for electromechanical effects
(2010-12-31)In a series of recent papers we demonstrated that coupled electro-mechanical effects can lead to pronounced contributions in band structure calculations of low dimensional semiconductor nanostructures (LDSNs) such as quantum ... -
BayFlux: A Bayesian Method to Quantify Metabolic Fluxes and their Uncertainty at the Genome Scale.
(2023-11-10)Metabolic fluxes, the number of metabolites traversing each biochemical reaction in a cell per unit time, are crucial for assessing and understanding cell function. 13C Metabolic Flux Analysis (13C MFA) is considered to ... -
Berry phase and spin precession without magnetic fields in semiconductor quantum dots
(2019)We investigate electric field control of spin manipulation through Berry phase in III-V semiconductor quantum dots. By utilizing degenerate and non-degenerate perturbation theories, we diagonalize the total Hamiltonian of ... -
Brain energetics plays a key role in the coordination of electrophysiology, metabolism and hemodynamics: evidence from an integrated computational model
(2019-06-05)The energetic needs of brain cells at rest and during elevated neuronal activation has been the topic of many investigations where mathematical models have played a significant role providing a context for the interpretation ... -
Breast cancer dormancy can be maintained by small numbers of micrometastases
(2010-12-31)Late relapse of breast cancer can occur more than 25 years after primary diagnosis. During the intervening years between initial treatment and relapse, occult cancers are maintained in an apparent state of dormancy that ... -
Brinicles as a case of inverse chemical gardens
(2013-12-31)Brinicles are hollow tubes of ice from centimeters to meters in length that form under floating sea ice in the polar oceans when dense, cold brine drains downward from sea ice to seawater close to its freezing point. When ... -
Causality, 'superluminality', and reshaping in undersized waveguides
(2012-12-31)We analyse the reshaping mechanism leading to apparently 'superluminal' advancement of a pulse traversing an undersized section of a waveguide. For frequencies below the first inelastic threshold (cut off one), there are ... -
Changes in Social and Clinical Determinants of COVID-19 Outcomes Achieved by the Vaccination Program: A Nationwide Cohort Study
(2022)Background: The objective of this study was to assess changes in social and clinical determinants of COVID-19 outcomes associated with the first year of COVID-19 vaccination rollout in the Basque population. Methods: A ... -
Chemical-garden formation, morphology, and composition. I. Effect of the nature of the cations
(2011-12-31)We have grown chemical gardens in different sodium silicate solutions from several metal-ion salts-calcium chloride, manganese chloride, cobalt chloride, and nickel sulfate-with cations from period 4 of the periodic table. ... -
Chemical-garden formation, morphology, and composition. II. Chemical gardens in microgravity
(2011-12-31)We studied the growth of metal-ion silicate chemical gardens under Earth gravity (1 g) and microgravity (μg) conditions. Identical sets of reaction chambers from an automated system (the Silicate Garden Habitat or SGHab) ... -
Chemoinformatic-guided engineering of polyketide synthases
(2019)Polyketide synthase (PKS) engineering is an attractive method to generate new molecules such as commodity, fine and specialty chemicals. A central challenge in PKS design is replacing a partially reductive module with a ... -
Chronic stimulation induces adaptive potassium channel activity that restores calcium oscillations in pancreatic islets in vitro
(2020-04-01)Insulin pulsatility is important to hepatic response in regulating blood glucose. Growing evidence suggests that insulin-secreting pancreatic β-cells can adapt to chronic disruptions of pulsatility to rescue this physiologically ... -
Classification of bursting patterns: A tale of two ducks
(2022-01-20)Bursting is one of the fundamental rhythms that excitable cells can generate either in response to incoming stimuli or intrinsically. It has been a topic of intense research in computational biology for several decades. ... -
Classification of resonance Regge trajectories and a modified Mulholland formula
(2011-12-31)We employ a simple potential model to analyze the effects which a Regge trajectory, correlating with a bound or a metastable state at zero angular momentum, has on an integral cross section. A straightforward modification ... -
Clinical correlates of mathematical modeling of cortical spreading depression: Single‐cases study
(2019-07-28)Introduction: Considerable connections between migraine with aura and cortical spreading depression (CSD), a depolarization wave originating in the visual cortex and traveling toward the frontal lobe, lead to the hypothesis ... -
