Spatially-distributed coverage optimization and control with limited-range interactions [PDF]

open access: yes, 2004
This paper presents coordination algorithms for groups of mobile agents performing deployment and coverage tasks. As an important modeling constraint, we assume that each mobile agent has a limited sensing/communication radius.

Clustering of Longitudinal Data: A Tutorial on a Variety of Approaches

open access: yesStatistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 1, February 2026.
ABSTRACT During the past two decades, methods for identifying groups with different trends in longitudinal data involving a single numeric outcome have become of increasing interest across many areas of research. To support researchers, we summarize the guidance from literature regarding the clustering of such data.

Some properties of WKB series

open access: yes, 1999
We investigate some properties of the WKB series for arbitrary analytic potentials and then specifically for potentials $x^N$ ($N$ even), where more explicit formulae for the WKB terms are derived.

A Unified Approach to High-Gain Adaptive Controllers [PDF]

open access: yes, 2009
It has been known for some time that proportional output feedback will stabilize MIMO, minimum-phase, linear time-invariant systems if the feedback gain is sufficiently large.

A practical guide to characterising ecological coexistence

open access: yesBiological Reviews, Volume 101, Issue 1, Page 195-220, February 2026.
ABSTRACT Coexistence is simultaneously one of the most fundamental concepts of ecology, and one of the most difficult to define. A particular challenge is that, despite a well‐developed body of research, several different schools of thought have developed over the past century, leading to multiple independent, and largely isolated, branches of ...

Robotic Needle Steering for Percutaneous Interventions: Sensing, Modeling, and Control

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 1, January 2026.
This review examines recent advances in robotic needle steering for percutaneous interventions, highlighting closed‐loop sensing, physics‐informed tissue‐needle interaction modeling, and real‐time trajectory planning and control. It synthesizes innovations in deep learning, fiber‐optic feedback, and adaptive control strategies, and outlines emerging ...

Stability Bias in Lagrangian (Back)tracking in Divergent Flows

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 1, January 2026.
Abstract Forward‐ and backward‐in‐time Lagrangian advection, used to determine fate and origin of material in the ocean, are mathematically consistent. However, their numerical computations are hampered by round‐off and truncation errors. Trajectory calculations are stable to errors (i.e., errors are dampened) in zones of velocity convergence and ...

Relative Periodic Solutions of the Complex Ginzburg-Landau Equation

open access: yes, 2005
A method of finding relative periodic orbits for differential equations with continuous symmetries is described and its utility demonstrated by computing relative periodic solutions for the one-dimensional complex Ginzburg-Landau equation (CGLE) with ...

Universal parametric correlations in the classical limit of quantum transport [PDF]

open access: yes, 2007
Quantum corrections to transport through a chaotic ballistic cavity are known to be universal. The universality not only applies to the magnitude of quantum corrections, but also to their dependence on external parameters, such as the Fermi energy or an ...

Exponential Convergent Second‐Order Sliding Mode Control Based on Barrier Lyapunov Function of State Constraint Robotic Manipulators

open access: yesIET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
A novel controller design integrates position error constraints using a barrier Lyapunov function, ensuring bounded tracking performance. The proposed control strategy ensures exponential convergence of tracking errors while preserving robustness against disturbances and uncertainties.
