Performance improvement of discrete‐time linear‐quadratic regulators applied to uncertain linear systems using the Tikhonov regularization method

open access: yesAsian Journal of Control, EarlyView.
Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

The evolving therapeutic landscape of spinal muscular atrophy – A scoping review of investigational agents, emerging delivery technologies and strategic innovations

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Spinal muscular atrophy (SMA) is a severe neuromuscular disease with emerging therapeutic complexity. This review aims to systematically map the global pipeline of investigational treatments for SMA. Using ClinicalTrials.gov and complementary international registries, we identified 21 planned or ongoing interventional trials from 2020 to 2025 targeting

A goodness‐of‐fit test for regression models with discrete outcomes

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Regression models are often used to analyze discrete outcomes, but classical goodness‐of‐fit tests such as those based on the deviance or Pearson's statistic can be misleading or have little power in this context. To address this issue, we propose a new test, inspired by the work of Czado et al.

Daily Ovarian Hormone Exposure and Loss of Control Eating in Adolescent Girls: A Stage 2 Registered Report

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective This Stage 2 Registered Report examined (1) the main effects and interaction of within‐person daily associations between ovarian hormones (i.e., estrogen, progesterone) and loss of control eating (LOCE), and (2) the within‐person mediating roles of food‐related reward anticipation and response inhibition. Methods Adolescent girls (n =

A Segmented Cross-Correlation Algorithm for Dynamic North Finding Using Fiber Optic Gyroscopes

open access: yesSensors
Fiber optic gyroscope (FOG)-based north finding is extensively applied in navigation, positioning, and various fields. In dynamic north finding, an accelerated turntable speed shortens the time required for north finding, resulting in a rapid north ...

Optical beam jitter control

open access: yesSPIE Proceedings, 2004
For several future imaging and communications spacecraft, a challenging area of technology development is the fine acquisition, tracking, and pointing (ATP) control of the spacecraft and its payload. For example, some spacecraft with large aperture(s) in the range of 10~30 m diameter requires a few arc-seconds accuracy, 10~15 nano-radians jitter, and a
