The Physician‐Scientist Pipeline for Pediatric Rheumatology – Current Landscape and Future Perspectives.

open access: yesArthritis Care &Research, Accepted Article.
Over the past 50 years, the science of pediatric rheumatology has grown exponentially due to an expansion in the understanding of complex rheumatic conditions and a surge in novel targeted therapeutics. Physician‐scientists in the field of pediatric rheumatology have played major roles in these advancements that have improved the care of children ...

Oscillatory properties of third-order quasilinear difference equations

open access: yesMalaya Journal of Matematik, 2013
Some new oscillation criteria are obtained for the third-order quasilinear difference equation $\Delta^2\left(p_n\left(\Delta x_n\right)^\alpha\right)-$ $q_n\left(\Delta x_n\right)^\alpha+r_n f\left(x_n\right)=0, n=0,1,2, \ldots$, where $\alpha>0$ is the ratio of odd positive integers.

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Extensions of the complex Jacobi iteration to simulate photonic wavelength scale components (abstract) [PDF]

open access: yes, 2006
We have extended the complex Jacobi iteration to simulate nonlinear optical components. The size of these components is comparable to the used wavelength (µm). In this paper we will give an overview of the technique and several simulation results.

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

open access: yesAdvanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

NEW METHODS FOR SOLVING ALGEBRAIC EQUATIONS [PDF]

open access: yes
Iteration methods are very useful in solving nonlinear algebraic equations. The most famous such method is Newton’s method deduced by first order Taylor expansion. In 2003, J. H.

Improved convergence of scattering calculations in the oscillator representation

open access: yes, 2012
The Schr\"odinger equation for two and tree-body problems is solved for scattering states in a hybrid representation where solutions are expanded in the eigenstates of the harmonic oscillator in the interaction region and on a finite difference grid in ...

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

open access: yesAdvanced Engineering Materials, EarlyView.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Analysis of API 5C3 failure prediction formulae for casing and tubing [PDF]

open access: yes, 2012
Due to the increasing demand for oil and gas, coupled with the fact that oil reserves are becoming rather scarce, the petroleum industry is pushed to drill and complete deeper wells. Threaded connections are often the weakest link in this process and are
