Waterfowl Move Less in Heterogeneous and Human‐Populated Landscapes, With Implications for Spread of Avian Influenza Viruses

open access: yesEcology Letters, Volume 29, Issue 1, January 2026.
We show that non‐migratory waterfowl movement distances are shorter in areas of high land cover heterogeneity and human population density, and that these movement distances are related to the spread of highly pathogenic avian influenza. These results suggest that habitat management could contribute to the spread of these viruses.

Adaptive fuzzy logic-based velocity observer for servo motor drives [PDF]

open access: yes, 2010
As the position transducers commonly used in industry do not inherently measure an instantaneous velocity, signal processing is generally required to improve the accuracy of velocity estimation at each sampling instant. This estimated signal is then used

Hybrid Deference, Hybrid Chance

open access: yesPhilosophy and Phenomenological Research, Volume 112, Issue 1, Page 214-233, January 2026.
ABSTRACT If you learn about one kind of chance and nothing else, then you should defer to those chances. But what if you learn about more than one kind of chance? In such “hybrid” cases, familiar chance‐credence principles, like the Principal Principle, go silent when they should intuitively speak.

Actuator Fault Estimation Based on Adaptive H-infinity Observer Technique

open access: yes, 2009
In adaptive observer methods for actuator fault estimation, the system has to satisfy the condition of the Strictly Positive Realness (SPR). However, some practical systems may fail to satisfy the SPR condition.

Nonlinear Output Feedback Control: An Analysis of Performance and Robustness [PDF]

open access: yes, 2004
By considering a non-singular performance cost functional, observer backstepping designs and adaptive observer backstepping designs are compared to high-gain observer designs for an output feedback system and a parametric output feedback system.
