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

Journal of Synchrotron Radiation, EarlyView.We present the analytic equations for a new grazing‐incidence mirror surface, a sagittal collimating diaboloid, and illustrate its advantages for higher‐throughput soft X‐ray spectrometer design.A major challenge in soft X‐ray spectroscopy is the efficient collection of the emitted X‐rays by grazing‐incidence mirrors.

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

A quadrature tau method for fractional differential equations with variable coefficients
, 2011 In this article, we develop a direct solution technique for solving multi-order fractional differential equations (FDEs) with variable coefficients using a quadrature shifted Legendre tau (Q-SLT) method.

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