The Coming Multi-Order World [PDF]

open access: yes, 2016
The article shows that the current international system is changing towards a completely new form of international system, conceptualized as a multi-order system. The suggestion for a multi-order world stands in contrast to three current narratives about

Toroidal‐Dipole‐Driven Polarization‐Selective Quasi‐BICs Enabling Wide‐Angle Near‐Field Image Display in Dielectric Metasurfaces

open access: yesAdvanced Physics Research, EarlyView.
This study presents toroidal‐dipole (TD)‐driven polarisation‐selective quasi‐bound states in the continuum (quasi‐BICs) in all‐dielectric metasurfaces, enabling transverse magnetic (TM)‐selective excitation with ultrahigh quality factors and wide‐angle‐stable polarisation‐dependent near‐field imaging.

Appropriate Mechanical Confinement Inhibits Multipolar Cell Division via Pole-Cortex Interaction

open access: yesPhysical Review X, 2023
Multipolar spindles are very rare in normal tissues, but they are much more prevalent in many tumors, which might be induced by the mechanical confinements from overcrowding microenvironments in tumors.

Vector chiral and multipolar orders in the spin-1/2 frustrated ferromagnetic chain in magnetic field

open access: yes, 2008
We study the one-dimensional spin-1/2 Heisenberg chain with competing ferromagnetic nearest-neighbor J_1 and antiferromagnetic next-nearest-neighbor J_2 exchange couplings in the presence of magnetic field.

Broadband Conductance Matching Effect in Conductive Metamirrors

open access: yesAdvanced Physics Research, EarlyView.
A conductance matching effect is revealed in conductive metamirrors whose input conductance can be broadband self‐matched to the free space when the conductivity‐thickness product equals 8 mS. This effect enables thickness‐invariant perfect absorption at low frequencies, and tunable resonances at higher‐order modes, providing new opportunities for ...

Far-field approximation for hydrodynamic interactions in parallel-wall geometry

open access: yes, 2005
A complete analysis is presented for the far-field creeping flow produced by a multipolar force distribution in a fluid confined between two parallel planar walls.

Microfluidic multipoles: theory and applications [PDF]

open access: yes, 2018
Microfluidic multipoles (MFMs) have been realized experimentally and hold promise for "open-space" biological and chemical surface processing. Whereas convective flow can readily be predicted using hydraulic-electrical analogies, the design of advanced ...

Hong Kong's non‐local undergraduate recruitment: Policies, institutional practices and student perspectives

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Beneath the Hong Kong government's enthusiasm for recruiting non‐local undergraduates—including students from the Chinese Mainland and other international regions—lies a longstanding gap in understanding the core meanings and drivers shaping the territory's expanding focus on inward international student mobility (ISM).

Radiofrequency ablation with monopolar cluster versus bipolar multipolar electrodes for the ablation of ⩾2.5 cm hepatocellular carcinoma

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine, 2016
Purpose: To compare the effectiveness of radiofrequency ablation using a monopolar cluster and a bipolar multipolar electrode for the ablation of (⩾2.5 cm) hepatocellular carcinoma. Methods: 34 patients with a single HCC (mean size, 4.46 ± 2.3 cm; range,

Multipolar second-harmonic generation from high-Q quasi-BIC states in subwavelength resonators

open access: yesNanophotonics, 2020
We put forward the multipolar model which captures the physics behind linear and nonlinear response driven by high-quality (high-Q) supercavity modes in subwavelength particles.
