Topology‐Optimized Bound States in the Continuum with High‐Q Acoustic Field Enhancement

Advanced Science, EarlyView.
This study presents a topology optimization method for acoustic metamaterials, achieving high‐Q resonances by redesigning a single unit cell within a periodic array. The design enables precise pressure confinement and energy trapping, validated through experiments.

Disciplined Geodesically Convex Programming [PDF]

arXiv
Convex programming plays a fundamental role in machine learning, data science, and engineering. Testing convexity structure in nonlinear programs relies on verifying the convexity of objectives and constraints. \citet{grant2006disciplined} introduced a framework, Disciplined Convex Programming (DCP), for automating this verification task for a wide ...

Uncover Hidden Physical Information of Soft Matter by Observing Large Deformation

Advanced Science, EarlyView.
Detecting internal abnormalities in soft matter remains challenging due to its heterogeneous nature. This study introduces a method that infers hidden physical properties by matching observed deformation with simulation through parallel Bayesian optimization.

Perceived safety in community and service settings among young adults experiencing homelessness: Differences by sexual and gender identity

American Journal of Community Psychology, Volume 70, Issue 3-4, Page 340-351, December 2022., 2022
Abstract Homelessness poses risks to the health and safety of young adults; particularly among sexual and gender minority (SGM) young adults. The current study sought to better understand service use and perceived safety in community and service settings among SGM and cisgender heterosexual (cis‐hetero) young adults experiencing homelessness. Data come

A note on the Serrin problem in the plane

Le Matematiche, 2008
We investigate the stability of the radial symmetry for the overdetermined Serrin problem in a planar convex set. More precisely, we prove that, whenever we properly perturb both the boundary conditions and the data, then a convex solution is “close” to ...

Realizing Intrinsically Ultralow and Glass‐Like Thermal Transport via Chemical Bonding Engineering

Advanced Science, EarlyView.
Lattice thermal conductivity can be effectively suppressed by introducing a S2 − anion into the bridging position between the Ag–Ag bond in the Ag6 octahedron, which weakens the Ag–Ag bond within the octahedral structure and enhances phonon‐phonon scattering rates. Abstract Crystals exhibiting glass‐like and low lattice thermal conductivity (κL$\kappa_{
