PAIR INTERACTION IN SPANISH LANGUAGE CLASSROOMS THAT ENROLL HERITAGE AND L2 LEARNERS
… framework, this study investigated the interactions of Spanish heritage language (HL) learners and Spanish L2 learners enrolled in the same class. Twenty-four intermediate-level learners of Spanish, organized in four HL-HL, four HL-L2, and four L2-L2 dyads, participated in the study. As …

Structure and interactions of colloidal particles at fluid interfaces
… monolayers depends crucially on the effective pair interaction potential between colloidal particles. In the first part of the thesis, we present two novel methods for extracting the pair potential from the two-dimensional radial distribution function of dense colloidal monolayers. The first is …

Nonlinear optical processes and the nearest neighbor distribution in rubidium vapor
… accurate calculations of nonlinear light-matter interactions, and calculations of these interactions using this framework are performed for a broad range of excitation conditions. In particular, the effects of femtosecond pulse parameters such as pulse duration, pulse energy, center wavelength, …

Capillary Assembly Of Microparticles On Curved Fluid Interfaces
… capsules in pharmaceutical industry. Capillary interaction holds tremendous promise as a tool to orient and assemble microparticles on interfaces between two immiscible fluids. Microparticles trapped at an interface deform the interface around them due to particle geometry, surface roughness, …

Attractive electrostatic self-assembly of ordered and disordered heterogeneous colloids
… stabilized by attractive electrostatic interactions. These crystals are colloidal analogues to ionic materials including zincblende, rocksalt, cesium chloride, and fluorite. A thermodynamic study revealed that the screening ratio, charge ratio, and monodispersity are critical parameters …

Probing DNA-Induced Colloidal Interactions and Dynamics with Scanning-Line Optical Tweezers
… materials is directed self-assembly, where the interactions among multiple species of suspended particles are intentionally designed to favor the self-assembly of a specific cluster arrangement or nanostructure. DNA provides a natural tool for directed particle assembly because DNA double helix …

Solution and Adsorption Characterization of Novel Water-Soluble Ionic Block Copolymers for Stabilization of Magnetite Nanoparticles
… star polymer models for brush extension and pair potential. Block copolymer micelles were first utilized for experimental validation by using the brush extension model to predict the size and the interaction model to predict the second virial coefficient, A2. Subsequently, the models were …

Stochastic dynamics in spatially extended physical and biological systems
… is power-law in form, as a consequence of the pair interaction of nearest neighbors in one dimension. In two dimensions, I show the presence of a pairing phase transition in a system of interacting dislocations with parallel Burgers vectors. The scaling exponent of the velocity distribution at …

A multiscale computational framework for cement paste
… that captures the essential structures and interactions at atomistic (~1 nm), colloidal (~100 nm), and microstructural (~100 [um) length scales. Models are developed and validated through appropriate experiments to ensure realistic configurations and interactions. We begin with the layered …

Droplets in an Electric Field: Surface Rheology, Coalescence and Rebound
<p>Electrocoalescence is the process in which pairs of conducting droplets suspended in a continuous dielectric (nonconducting) liquid phase are drawn together and merge upon the application of an electric field. The electric field polarizes each of the droplets in the field direction. The …

Effect of selection for interspecific behavior on stress and conspecific behavior in tame and aggressive foxes
… populations regarding their response to human interaction, whether the long-term selection for tame and aggressive behavior towards humans has an influence on conspecific behavior has yet to be addressed. Our second aim was to investigate how selection for tameness and aggression towards humans …

Modeling of Effect of Alloying Elements on Radiation Damage in Metallic Alloys
… atom (SIA). To achieve this, the Fe-Cr cross pair interaction in the interatomic potential was modified by multiplying a scaling factor so that the solute-SIA binding energy varies linearly from positive to negative values. It is found that the solute interstitial fraction has a strong …
