Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture

open access: yesAdvanced Healthcare Materials, EarlyView.
This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Linear Quadratic Games with Costly Measurements

open access: yes, 2017
In this work we consider a stochastic linear quadratic two-player game. The state measurements are observed through a switched noiseless communication link. Each player incurs a finite cost every time the link is established to get measurements.

Spatially‐Controlled Planar Guided Crystallization of Low‐Loss Phase Change Materials for Programmable Photonics

open access: yesAdvanced Materials, EarlyView.
The concept of spatially‐controlled planar guided crystallization is a novel method for programming the growth of optically homogeneous low‐loss Sb2S3 phase‐change material (PCM), leveraging the directional crystallization within confined channels.

On Quadratic Programming with a Ratio Objective

open access: yes, 2011
Quadratic Programming (QP) is the well-studied problem of maximizing over {-1,1} values the quadratic form \sum_{i \ne j} a_{ij} x_i x_j. QP captures many known combinatorial optimization problems, and assuming the unique games conjecture, semidefinite ...

Ultra‐Improved Interfacial Strength Between Metallic Surface and Polyurethane via Cost‐Effective Anodizing Process

open access: yesAdvanced Materials Interfaces, EarlyView.
SAA significantly enhanced Al/PU bonding, increasing SLSS by up to 920% and fracture energy by 15 100% through optimized micro‐nano porous surfaces. RSM identified the optimal anodizing conditions, while ML confirmed sulfuric acid concentration and roughness as dominant predictors of strength.

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

open access: yesAdvanced 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 ...

Using concave optimization methods for inexact quadratic programming problems with an application to waste management

open access: yesJournal of Inequalities and Applications, 2021
Quadratic programming is potentially capable of strategic decision making in real world problems. However, practical problems rarely conform to crisp parameters, and hence the prospects of these problems with inexact parameters are inevitably higher. The
