Inner‐Layer Asymptotics in Partially Perforated Domains: Coupling Across Flat and Oscillating Interfaces

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The article examines a boundary‐value problem in a bounded domain Ωε$$ {\Omega}_{\varepsilon } $$ consisting of perforated and imperforate regions, with Neumann conditions prescribed at the boundaries of the perforations. Assuming the porous medium has symmetric, periodic structure with a small period ε$$ \varepsilon $$, we analyze the limit ...

What If Each Voxel Were Measured With a Different Diffusion Protocol?

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Expansion of diffusion MRI (dMRI) both into the realm of strong gradients and into accessible imaging with portable low‐field devices brings about the challenge of gradient nonlinearities. Spatial variations of the diffusion gradients make diffusion weightings and directions non‐uniform across the field of view, and deform perfect ...

Personalized Differential Privacy for Ridge Regression Under Output Perturbation

Naval Research Logistics (NRL), EarlyView.
ABSTRACT The increased application of machine learning (ML) in sensitive domains requires protecting the training data through privacy frameworks, such as differential privacy (DP). Traditional DP enforces a uniform privacy level ε$$ \varepsilon $$, which bounds the maximum privacy loss that each data point in the dataset is allowed to incur.

On the Laplace-Beltrami operator on the oscillator group

The oscillator groups play a distinguished role among all solvable simply connected Lie groups, since a result by A. Medina shows that they are, except for direct extensions with Euclidean groups, the only non- commutative groups in this class which do admit a bi-invariant Lorentzian metric. If G is an oscillator group, then there exists a basis \(T,X_

Surgical Outcomes of Acute Mastoiditis in Pediatric Patients: A Pediatric Health Information System Study

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective To evaluate outcomes of surgically treated acute mastoiditis (AM) in pediatric patients using the Pediatric Health Information System (PHIS). Study Design Retrospective cohort study. Setting Pediatric tertiary care centers participating in the PHIS. Methods Children aged 0 to 18 years with AM treated from January 1, 2016, to December
