Solution of magnetohydrodynamic flow in a rectangular duct by differential quadrature method

open access: yes, 2004
The polynomial based differential quadrature and the Fourier expansion based differential quadrature method are applied to solve magnetohydrodynamic (MHD) flow equations in a rectangular duct in the presence of a transverse external oblique magnetic ...

Transforming Paper into Plasmonic Sensors: One‐Step Fabrication of High‐Enhancement SERS Nanosubstrates via Surface Energy Control

open access: yesSmall Methods, EarlyView.
Cellulose paper is transformed into a high‐performance plasmonic sensor through a process called SILVERED, which involves single‐step vapor deposition onto fluorosilanized fibers. Surface‐energy contrast drives uniform silver nanoparticle growth with sub‐10 nm hot‐spot gaps, achieving 2 pM detection of rhodamine B.

AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.

Preemptive Entry and Technology Diffusion: The Market for Drive‐In Theaters

open access: yesThe RAND Journal of Economics, EarlyView.
ABSTRACT This article studies entry preemption in new industries. We first test a key prediction of dynamic entry games: Entry preemption is most relevant in intermediate‐sized markets, where firms face highest uncertainty about future entry. Using US drive‐in theater market (1945–1957) data, we find robust evidence for this non‐monotonic relationship ...

Solution of the Blasius and Sakiadis equation by generalized iterative differential quadrature method

open access: yes, 2011
The Blasius and Sakiadis equation was solved earlier with different numerical methods. In this study, it was solved by using the generalized iterative differential quadrature method (GIDQM).

neonSoilFlux: An R package for continuous sensor‐based estimation of soil CO2 fluxes

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Accurate quantification of soil carbon fluxes is essential to reduce uncertainty in estimates of the terrestrial carbon sink. However, these fluxes vary over time and across ecosystem types and so, it can be difficult to estimate them accurately across large scales.
