Master-Slave Composite Vibration Control of a Mobile Flexible Manipulator via Synchronization Optimization of Observation and Feedback

Complexity, 2019
The elastic vibration of the flexible manipulator is the key problem to be solved before its effective application. The mobile flexible manipulator system (MFMS), under variable load conditions, is taken as the research object.

Probing Ultrafast Coherent Bandgap Modulation in Monolayer WSe2 by Nonlinear Optics

Advanced Optical Materials, EarlyView.
This work sheds light on how resonant nonlinear optics blursthe line between perturbative and non‐perturbative nonlinear optics. Measured deviationsfrom the quadratic second‐harmonic scaling near the excitonic resonance arisefrom optical Stark and Bloch‐Siegert shifts. The experimental results arefurther underpinned by analytical and numerical analysis

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

Advanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

Decoding Human Placental Cellular and Molecular Responses to Obesity and Fetal Growth

Advanced Science, EarlyView.
Women with obesity often deliver large‐for‐gestational‐age (LGA) infants. Single‐nucleus RNA sequencing of term placenta reveals that hypoxia and TNF‐α signaling in syncytiotrophoblasts are featured in maternal obesity, but inflammatory signatures in Hofbauer cells and response to lipid or carbohydrate metabolism in fibroblasts are specific to LGA.

Hamiltonian Theory and Computation of Optimal Probability Density Control in High Dimensions

We develop a general theoretical framework for optimal probability density control and propose a numerical algorithm that is scalable to solve the control problem in high dimensions. Specifically, we establish the Pontryagin Maximum Principle (PMP) for optimal density control and construct the Hamilton-Jacobi-Bellman (HJB) equation of the value ...

Lithium and Vanadium Intercalation into Bilayer V2Se2O: Ferrimagnetic–Ferroelastic Multiferroics and Anomalous and Spin Transport

Advanced Science, EarlyView.
Li‐ and V‐intercalated V2Se2O bilayers possess intralayer ferrimagnetic and interlayer ferromagnetic orders, alongside ferroelasticity, in‐plane uniaxial magnetic anisotropy, half‐metal/enhanced spin splitting, the anomalous Hall effect, giant magnetoresistance, tunneling magnetoresistance, near‐perfect spin filtering effect, spin Seebeck effect, and ...

A Quantum Framework for Protein Binding‐Site Structure Prediction on Utility‐Level Quantum Processors

Advanced Science, EarlyView.
This study presents a hybrid quantum‐classical framework for accurate prediction of protein structures on utility‐level quantum processors. We evaluate the practical application of the Variational Quantum Eigen‐solver (VQE) in protein structure prediction and demonstrate its superiority over state‐of‐the‐art deep learning methods in molecular docking ...

High-Resolution Nanoscale Solid-State Nuclear Magnetic Resonance Spectroscopy

Physical Review X, 2018
We present a new method for high-resolution nanoscale magnetic resonance imaging (nano-MRI) that combines the high spin sensitivity of nanowire-based magnetic resonance detection with high-spectral-resolution nuclear magnetic resonance (NMR) spectroscopy.

Paradoxical Topological Soliton Lattice in Anisotropic Frustrated Chiral Magnets

Advanced Science, EarlyView.
The article describes the discovery of a stable skyrmion‐antiskyrmion lattice (S‐AL) in anisotropic frustrated chiral magnets. This lattice has a net‐zero topological charge due to a balanced population of skyrmions and antiskyrmions. This is a paradoxical finding since these particles normally annihilate each other.

Effective equilibrium theory of quantum light-matter interaction in cavities for extended systems and the long wavelength approximation

Communications Physics
When light and matter interact strongly, the resulting hybrid system inherits properties from both constituents, allowing one to modify the material behavior by engineering the surrounding electromagnetic environment.
