Connection Formulae between Ellipsoidal and Spherical Harmonics with Applications to Fluid Dynamics and Electromagnetic Scattering

Advances in Mathematical Physics, 2015
The environment of the ellipsoidal system, significantly more complex than the spherical one, provides the necessary settings for tackling boundary value problems in anisotropic space.

Local Spherical Harmonics for Facial Shape and Albedo Estimation

IEEE Access, 2020
In this paper, we present a novel facial albedo and 3D shape recovery method with a local spherical harmonic illumination model. From a face in an image, the proposed method can produce a high-quality 3D shape and albedo using a novel parameterization of

Remote‐Controllable Immune‐Priming Spot Formation Via Nanocomplexed Hydrogel‐Assisted Histotripsy: Immunoasis

Advanced Materials, EarlyView.
A novel immunotherapeutic strategy combines injectable, adjuvant‐loaded hydrogels with externally controlled histotripsy to create immune‐priming sites within tumors. This approach generates millimeter‐sized immune‐activated lesions with flexible, patient‐tailored treatment scheduling, enabling precise immune activation through tumor ablation‐mediated ...

Ubiquitous Antiparallel Domains in 2D Hexagonal Boron Nitride Uncovered by Interferometric Nonlinear Optical Imaging

Advanced Materials, EarlyView.
Interferometric second‐harmonic generation (SHG) imaging reveals the ubiquitous formation of antiparallel domains in CVD‐grown 2D hexagonal boron nitride. By resolving lattice orientation and SHG phase, hidden domain structures and disorder become visible over large areas. The SHG intensity quantitatively tracks crystalline quality across growth routes,

Scalar-Tensor Anti-Cross-Correlation does not Help to Reconcile the Tension between BICEP2 and Planck

, 2014
We examine the recent proposal [1] that the anti-cross-correlation of the scalar and tensor primordial fluctuations reconciles the tension between BICEP2 and Planck observations.

Enabling Real‐Time, Non‐Ionizing 3D Imaging of Implantable Magnetic Cements Using Magnetic Particle Imaging

Advanced Materials Interfaces, EarlyView.
This study reports the first implantable resin cement capable of orientation‐sensitive Magnetic Particle Imaging (MPI). By coating the cement with an ultrathin iron film, the authors achieve a strong, angle‐dependent MPI signal that enables non‐ionizing, real‐time tracking of both implant position and orientation, opening new possibilities for safe ...

Compilation of the regional quasigeoid model for New Zealand using the discretised integral-equation approach

Journal of Geodetic Science, 2012
We evaluate the new regional quasigeoid model (OTG12) for New Zealand using the method which utilises the discretised integral equation approach for computing the near-zone contribution.
