All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

open access: yesAdvanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Early Radiation Therapy Response Assessment Using Multi‐Scale Photoacoustic Imaging

open access: yesAdvanced Science, EarlyView.
Tomographic and mesoscopic photoacoustics capture intratumoural features of radioresistance and response. ABSTRACT There is a critical unmet clinical need to identify biomarkers that predict and detect radiation therapy (RT) response in cancer. Using the unique capabilities of multi‐scale photoacoustic imaging (PAI) to depict tumor oxygenation and ...

Regression Models for Ordinal Data

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1980
Summary A general class of regression models for ordinal data is developed and discussed. These models utilize the ordinal nature of the data by describing various modes of stochastic ordering and this eliminates the need for assigning scores or otherwise assuming cardinality instead of ordinality.

Cellular Snowballing: Cell Adhesion and Migration Drive the Self‐Assembly of Cell‐Microgel Biohybrid Spheroids

open access: yesAdvanced Science, EarlyView.
A new class of biohybrid spheroids is engineered through the self‐assembly of adherent cells and extracellular matrix‐mimetic hydrogel microparticles (microgels). By mimicking a snowballing effect, this approach enables scalable formation of porous, millimeter‐scale spheroids with enhanced cell viability and molecular diffusion.

Assessing multivariate predictors of financial market movements: A latent factor framework for ordinal data

open access: yes, 2008
Much of the trading activity in Equity markets is directed to brokerage houses. In exchange they provide so-called "soft dollars," which basically are amounts spent in "research" for identifying profitable trading opportunities.

Solid Harmonic Wavelet Bispectrum for Image Analysis

open access: yesAdvanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Learning a bayesian network from ordinal data [PDF]

open access: yes
Bayesian networks are graphical models that represent the joint distributionof a set of variables using directed acyclic graphs. When the dependence structure is unknown (or partially known) the network can be learnt from data.

A Photothermal‐Responsive PRP‐Loaded Hydrogel Engineered With Composite Nanobottle for Controllable Delivery of Growth Factors and Multifunctional Therapy of Diabetic Wounds

open access: yesAdvanced Science, EarlyView.
A photothermal‐responsive engineered platelet‐rich plasma hydrogel (CNB‐ePRP) incorporated with thrombin‐functionalized composite nanobottle was developed, which enables in situ PRP activation, on‐demand growth factor release, multifunctionality, and personalized antimicrobial loading for treatment of diabetic wounds. The CNB‐ePRP hydrogel demonstrated
