An Item Analysis of the Instability of Parent Report Scores on the Pediatric Evaluation of Disability InventoryDownload
Purpose: To evaluate item instability of the Pediatric Evaluation of Disability Inventory – Functional Skills Scale completed by parents. Methods: Scoring instability was analyzed between baseline and after 6 months of intervention (T1-T2) on 113 children and between end of intervention and 3...
Abstract: In very loose sand, the ratio M-p of shear stress to mean normal stress at the peak point of the undrained effective stress path (UESP) is very close to the stress ratio M at the peak point of the capped yield surface. Stress ratios M-p can therefore be used in constructing yield...
Electrodynamics of magnetosphere‐ionosphere coupling and feedback on magnetospheric field line resonancesDownload
We present a new dynamic model that describes coupling between standing inertial or ion-acoustic-gyroradius-scale shear Alfven waves, compressional modes, and auroral density disturbances. The model is applied to the excitation of field line resonances (FLRs) in dipolar and stretched geomagnetic...
Electrically induced instability of thin liquid films is a contactless pattern transfer method, often called electrohydrodynamic (EHD) lithography, which has gained extensive attention due to its ability in creation of novel micro- and nano-sized structures. The need for powerful microprocessors...
We report upon an experimental study of internal gravity waves generated by the large-amplitude vertical oscillations of a circular cylinder in uniformly stratified fluid. Quantitative measurements are performed using a modified synthetic schlieren technique for strongly stratified solutions of...
Ethical reasoning in normative and practical ethics is typically conducted by working back and forth between intuitions about both general moral principles (e.g., suffering is bad) and particular cases (e.g., that I must prevent a specific person from suffering). These two types of...
Nonlinearity in the Navier-Stokes equations can originate from a variety of sources, such as contributions stemming from the advective term, constitutive closure models or external factors such as chemical reactions and capillarity. Needless to say, a combination of any of the above sources has...
Computational simulations of a perturbed vortex ring are performed to recreate and understand the instability seen in impacting water droplet experiments. Three initial conditions are tried to respectively trigger a Widnall instability, a Rayleigh centrifugal instability, and a vortex breakdown...
Abstract: When the stress-induced risks to a projects warrant it, in situ stress must be measured. However, as the stress-induced risks increase, i.e.. the stress magnitudes approach the rock mass strength, the confidence in commonly used stress measurement techniques decrease. The design of...
We present a case study of Field Line Resonances (FLRs) in the dayside magnetosphere, observed in both electric and magnetic field components at multiple L-shells near the equator. The event measured by the five THEMIS probes and the nearby GOES and Geotail satellites provides a unique...
