Measuring efficiency of Tunisian schools in the presence of quasi-fixed inputs: A bootstrap data envelopment analysis approach [PDF]

The objective of this paper is to measure the efficiency of high schools in Tunisia. We use a statistical Data Envelopment Analysis (DEA)-bootstrap approach with quasi-fixed inputs to estimate the precision of our measure.

A Generalizable Multimodal Model for Treatment‐Stratified Risk and Survival Assessment under Real‐World Constraints: A Multi‐Center Study of Colorectal Cancer

Advanced Science, EarlyView.
DAIMS is a multimodal model for treatment stratified risk and survival assessment in colorectal cancer. Training draws on pathology, genomics, and clinical reports, yet inference requires only whole slide images, and adaptation to new cohorts proceeds without target survival outcomes.

Long‐Term Human Skin Platform for Modeling Chronic Inflammation, Environmental Stress, and Therapeutic Intervention

Advanced Science, EarlyView.
An advanced, long‐term human skin platform maintains native skin structure and key tissue functions for up to four weeks. The platform models chronic inflammation, aging‐related skin changes, and UVB damage, enabling drug and topical interventions—including anti‐inflammatory therapy, senolytic treatment, and sunscreen—to be evaluated in intact human ...

Bootstrap Hypothesis Testing [PDF]

This paper surveys bootstrap and Monte Carlo methods for testing hypotheses in econometrics. Several different ways of computing bootstrap P values are discussed, including the double bootstrap and the fast double bootstrap.

Blue Light Receptor PHR2‐Mediated Spectrum Antiviral Immunity

Advanced Science, EarlyView.
Blue light suppresses RBSDV through the blue‐light receptor ZmPHR2, which interacts with ZmISP in chloroplasts to trigger ROS burst and antiviral defense. The viral effector P6 enhances ZmPHR2–ZmISP interaction, alters their distribution, and suppresses ROS.

Bootstrapping heteroskedastic regression models: wild bootstrap vs. pairs bootstrap [PDF]

In regression models, appropriate bootstrap methods for inference robust to heteroskedasticity of unknown form are the wild bootstrap and the pairs bootstrap. The finite sample performance of a heteroskedastic-robust test is investigated with Monte Carlo

Foundation Model‐Enabled Pathology‐Informed MRI Model for Preoperative Prediction of Vessels Encapsulating Tumor Clusters in Resectable Hepatocellular Carcinoma: A Multicenter Retrospective Study

Advanced Science, EarlyView.
PIVOT uses pathology‐derived morphologic and vascular representations from postoperative H&E and CD34 whole‐slide images to guide model development, while clinical inference requires only preoperative multiparametric MRI. Across five centers, PIVOT enabled accurate preoperative assessment of vessels encapsulating tumor clusters, stratified patients by ...

DATA-DRIVEN RATE-OPTIMAL SPECIFICATION TESTING IN REGRESSION MODELS [PDF]

We propose new data-driven smooth tests for a parametric regression function. The smoothing parameter is selected through a new criterion that favors a large smoothing parameter under the null hypothesis.

Mode‐Resolved Phonon Dynamics Under Chemical Pressure in SnTe Thermoelectrics

Advanced Science, EarlyView.
Chemical pressure reshapes low‐energy optical phonons in SnTe, altering their dispersion and scattering with heat‐carrying acoustic modes. Positive and negative pressure states modify phonon frequencies and lifetimes in distinct ways, revealing how mode‐selective lattice perturbations regulate acoustic–optical interactions and suppress lattice thermal ...
