Origins of neotropical leafy Hepaticae [PDF]

open access: yes, 1990
The neotropical hepatic flora, predominantly constituted by members of the Jungermanniales and Metzgeriales, includes a disproportionate number of genera which are endemic (over 38) and a number which evidently originated here but have shown slight and ...

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

open access: yesInternational Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

A new way of editing a flora [PDF]

open access: yes
Modern electronic tools have become common tools of most scientists. Flora writers and other botanists producing large manuscripts with a certain fixed structure may go even further and use the so-called Mail Merge option in a word processor such as ...

Vascular flora evolution in the major Mediterranean islands [PDF]

open access: yes, 2012
Characteristics of Mediterranean island floras are analyzed with stress on endemic units. On these bases the main relationships between the major Mediterranean areas and the inland territories with the strongest floristic affinities are analyzed. Finally

Hopfield Neural Networks for Online Constrained Parameter Estimation With Time‐Varying Dynamics and Disturbances

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

A preliminary study on the affinities of Philippine, Bornean and New Guinean hepatics [PDF]

open access: yes, 1990
The generic and specific affinities of the Philippine, Bornean and New Guinean hepatic floras were analyzed by calculating the Kroeber's percentage of similarity on the basis of recently published checklists.

An Adaptive Human Pilot Model With Reaction Time Delay for Enhanced Adaptive Control in Piloted Systems

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces an adaptive human pilot model that captures pilot time‐delay effects in adaptive control systems. The model enables the prediction of pilot–controller interactions, facilitating safer integration and improved design of adaptive controllers for piloted applications.

The macroecology of island floras

open access: yesFrontiers of Biogeography, 2015
Islands are key model systems in biogeography and ecology. However, standardized data on environmental characteristics of the large number of islands worldwide have so far been lacking, and the effects of these characteristics on island ecology and ...

Floristics and distribution of Wattle Dry Sclerophyll Forests and Scrubs in north-eastern New South Wales [PDF]

open access: yes, 2013
Acacia blakei forests and scrubs of north-eastern NSW are described and compared to similar vegetation found in the south-east of the state, primarily dominated by Acacia silvestris.
