Generating Root-Finder Iterative Methods of Second Order: Convergence and Stability

open access: yesAxioms, 2019
In this paper, a simple family of one-point iterative schemes for approximating the solutions of nonlinear equations, by using the procedure of weight functions, is derived. The convergence analysis is presented, showing the sufficient conditions for the

The Cow or the Credit: Causal Relationship Between California Dairy Herd Consolidation and Anaerobic Digesters

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The California dairy industry has experienced considerable consolidation over the past 30 years. During this period, there has also been substantial technological innovation, implementation of the state's Low Carbon Fuel Standard program, and rapid adoption of anaerobic digesters.

Scaling solutions in quintessential inflation

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
In quintessence scalar field theories, the presence of scaling solutions are important during the radiation and matter epoch due to having their attractor character.

Data‐Guided Photocatalysis: Supervised Machine Learning in Water Splitting and CO2 Conversion

open access: yesAdvanced Intelligent Discovery, EarlyView.
This review highlights recent advances in supervised machine learning (ML) for photocatalysis, emphasizing methods to optimize photocatalyst properties and design materials for solar‐driven water splitting and CO2 reduction. Key applications, challenges, and future directions are discussed, offering a practical framework for integrating ML into the ...

Water Management of the Delaware River Basin: A staff compilation of planning assumptions, policies, programs, data, and a means of managing the Basin's water resources.

open access: yes, 1975
The adoption of the Delaware River Basin Compact in 1961 made possible the joint exercise of sovereign powers over the water resources of the Delaware River Basin in the common interest of the people of the region.

Random Boolean Networks and Evolutionary Game Theory [PDF]

open access: yes, 2002
Recent years have seen increased interest in the question of whether it is possible to provide an evolutionary game theoretic explanation for certain kinds of social norms. These explanatory approaches often rely on the fact that, in certain evolutionary

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws

open access: yesAdvanced Intelligent Discovery, EarlyView.
The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...

On Chaotic Attractors Whose Basins of Attraction Coincide with the Whole Space

open access: yesJournal of Optimization, Differential Equations and Their Applications
A new type of chaotic attractors, whose basin of attraction is the entire phase space, is considered. The main difference between these attractors and the known ones is that any trajectory starting from the basin of attraction first enters a unique ...

Basin of Attraction through Invariant Curves and Dominant Functions

open access: yesDiscrete Dynamics in Nature and Society, 2015
We study a second-order difference equation of the form zn+1=znF(zn-1)+h, where both F(z) and zF(z) are decreasing. We consider a set of invariant curves at h=1 and use it to characterize the behaviour of solutions when h>1 and when ...
