Personalized Differential Privacy for Ridge Regression Under Output Perturbation

Naval Research Logistics (NRL), Volume 73, Issue 4, Page 525-537, June 2026.
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.

Processing‐Dependent Performance of the LiNiO2 Cathode in Lithium‐Ion Batteries

Batteries &Supercaps, Volume 9, Issue 5, May 2026.
Processing‐dependent effects on the LiNiO2 cathode are investigated, demonstrating how the size of the pCAM particles, the method of mixing the hydroxide precursors, and the exposure to various atmospheres during the sieving process alter the microstructure, defect chemistry, and surface composition, and ultimately affect the cycling performance and ...

Multistage Spectral Relaxation Method for Solving the Hyperchaotic Complex Systems

The Scientific World Journal, 2014
We present a pseudospectral method application for solving the hyperchaotic complex systems. The proposed method, called the multistage spectral relaxation method (MSRM) is based on a technique of extending Gauss-Seidel type relaxation ideas to systems ...

Next Generation 7 Tesla Arterial Spin Labeling With Rotated Spiral Acquisition Enables Mesoscale Resolution in 3D Brain Perfusion and Functional MRI

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2702-2717, May 2026.
ABSTRACT Purpose To achieve high resolution (≤ 1 mm isotropic) whole‐brain perfusion imaging at 7 T with next generation ASL pulse sequence, reconstruction algorithm, and MRI hardware. Methods We capitalized on three major innovations: (1) FLASH‐based pseudo‐Continuous ASL (pCASL) sequence with rotated golden‐angle stack‐of‐spirals (rGA‐SoS) sampling; (

Heights of Butterfly Trees

Random Structures &Algorithms, Volume 68, Issue 3, May 2026.
ABSTRACT Binary search trees (BSTs) are fundamental data structures whose performance is largely governed by tree height. We introduce a block model for constructing BSTs by embedding internal BSTs into the nodes of an external BST—a structure motivated by parallel data architectures—corresponding to composite permutations formed via Kronecker or ...

FAST CALCULATION OF ALL STABILIZING GAINS FOR DISCRETE-TIME SYSTEMS

Electrica, 2005
In this paper, two methods for calculating all stabilizing gains for discrete-time systems are given. The first method focuses on converting the problem using a bilinear transformation and then applying a previously developed theorem for continuous time ...

Substitution of Ti by Nb in Maraging Steel: Effects on Strengthening Mechanisms and Crystallographic Behavior

steel research international, Volume 97, Issue 5, Page 2672-2692, May 2026.
This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.

Decomposing Shadow Prices Under Climate‐Driven Growth Scenarios: Insights From an Elk Herd Case Study

Natural Resource Modeling, Volume 39, Issue 2, May 2026.
ABSTRACT Natural capital accounting provides a framework for integrating ecological processes with economic valuation, but the mechanics of shadow price formation often remain opaque to resource managers and policymakers. Using the Clarks Fork elk herd in northwestern Wyoming as a case study, we decompose the shadow price of natural capital into its ...

Chebyshev collocation for linear, periodic ordinary and delay differential equations: a posteriori estimates

, 2004
We present a Chebyshev collocation method for linear ODE and DDE problems. We first give a posteriori estimates for the accuracy of the approximate solution of a scalar ODE initial value problem. Examples of the success of the estimate are given.
