Influence of Secondary Currents on Solute Dispersion in Curved Open Channels

Journal of Applied Mathematics, 2012
The dispersion coefficient tensor including off-diagonal components was introduced in the flow with secondary currents, which is called skewed shear flow dispersion (SSFD) coefficient tensor, in this paper.

Hadley circulations and large scale motions of moist convection in the two dimensional numerical model

, 1995
As a tool for understanding the meridional circulation of the atmosphere, a two-dimensional ( latitude -- height ) numerical model is used to clarify the relationship between the Hadley circulation and large-scale motions associated with moist convection.

Deformation and Degradation in 18650 Li‐Ion Cells Under Freeze‐Thaw Cycling

Advanced Functional Materials, EarlyView.
This study investigates the impact of freezethaw degradation of 18650 cells via combined electrochemical and x‐ray imaging studies. High‐resolution synchrotron X‐ray tomography reveals deformation of the jelly‐roll structure and delamination of electrode active materials in cells cycled at 1C and 4C. These structural changes are quantitatively assessed

Gyroscopically Stabilized Robot: Balance and Tracking

International Journal of Advanced Robotic Systems, 2008
The single wheel, gyroscopically stabilized robot - Gyrover, is a dynamically stable but statically unstable, underactuated system. In this paper, based on the dynamic model of the robot, we investigate two classes of nonholonomic constraints associated ...

Direct Imaging of Hydrogen‐Driven Dislocation and Strain Field Evolution in a Stainless Steel Grain

Advanced Materials, EarlyView.
Using in situ Bragg coherent X‐ray diffraction imaging, 3D nanoscale strain maps of a stainless steel grain were measured during hydrogen charging. Results show dislocation relaxation and climb, elucidating the role of point defects in hydrogen‐modified deformation behavior.

Spatiotemporally Resolved Orbital Hall Effect in a Topological Semimetal

Advanced Materials, EarlyView.
Real‐space mapping of orbital angular momentum (OAM) transport is achieved using contact‐free polarimetric terahertz spectroscopy. This principle is applied to the topological semimetal Td‐WTe2, revealing the spatial separation of electrons into two distinct regions characterized by opposite out‐of‐plane OAM (±Lz).

Handing-over motion model based on analyses of hand motions and voice utterances of humans

Nihon Kikai Gakkai ronbunshu, 2014
In this paper, we propose a hand-over motion model based on analyses of hand motions and voice utterances of humans. This model generates a motion in which a robot hands over an object to a human accompanied by a voice greeting.

Polyphenol‐Mediated Engineering of Lipid Nanoparticles With Crystalline Mesophases

Advanced Materials, EarlyView.
A polyphenol‐mediated strategy enables the one‐step formation of lipid nanoparticles with nonlamellar mesophases, including micellar cubic and hexagonal structures. These highly ordered nanostructures accommodate a wide range of cargos—from metal ions to mRNA—and offer a modular and versatile platform for constructing functional lipid‐based delivery ...
