Timescale analyses of fluctuations in coexisting populations of a native and invasive tree squirrel. [PDF]
Ecol Evol, 2022 This study documents long timescale variation in natural populations of conservation interest, shows that long timescale variation can accelerate the loss of species diversity, and provides evidence that the timescales of environmental fluctuations have increased in recent times. These results have broad implications for the impact of climate change on

Self‐organizing systems in the construction industry
Engineering Reports, Volume 5, Issue 11, November 2023., 2023 Self‐organization processes are ubiquitous. The principles of complex adaptive systems are transferred from natural to artificial systems. Connections are made to the construction industry and construction sites are described as cyber‐physical systems in which, for example, robots act as agents in subsystems.

Solution methods to the nearest rotation matrix problem in ℝ3: A comparative survey
Numerical Linear Algebra with Applications, Volume 30, Issue 5, October 2023., 2023 Abstract Nowadays, the singular value decomposition (SVD) is the standard method of choice for solving the nearest rotation matrix problem. Nevertheless, many other methods are available in the literature for the 3D case. This article reviews the most representative ones, proposes alternative ones, and presents a comparative analysis to elucidate their

Size Distributions Reveal Regime Transition of Lake Systems Under Different Dominant Driving Forces
Water Resources Research, Volume 59, Issue 8, August 2023., 2023 Abstract Power law size distribution is found to associate with fractal, self‐organized behaviors and patterns of complex systems. Such distribution also emerges from natural lakes, with potentially important links to the dynamics of lake systems. But the driving mechanism that generates and shapes this feature in lake systems remains unclear. Moreover,

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 100, Issue 5, May 2020., 2020 Fifty years have passed since Truesdell's seminal paper on the origin and status of the balance for the moment of momentum was published in ZAMM. It is time to take stock: Important new developments in the theory of generalized continua with internal degrees of freedom and some fascinating fundamental applications need to be pointed out….

A New Class of Halley’s Method with Third‐Order Convergence for Solving Nonlinear Equations
Journal of Applied Mathematics, Volume 2020, Issue 1, 2020., 2020 In this paper, we present a new family of methods for finding simple roots of nonlinear equations. The convergence analysis shows that the order of convergence of all these methods is three. The originality of this family lies in the fact that these sequences are defined by an explicit expression which depends on a parameter p where p is a nonnegative ...

PSEM Approximations for Both Branches of Lambert W Function with Applications
Discrete Dynamics in Nature and Society, Volume 2019, Issue 1, 2019., 2019 Transcendental functions are a fundamental building block of science and engineering. Among them, a relatively new function denominated as Lambert W is highlighted. The importance of such function relies on the fact that it can perform novel isolation of variables.

Fixed Point and Newton’s Methods in the Complex Plane
Journal of Complex Analysis, Volume 2018, Issue 1, 2018., 2018 We revisit the necessary and sufficient conditions for linear and high order of convergence of fixed point and Newton’s methods in the complex plane. Schröder’s processes of the first and second kind are revisited and extended. Examples and numerical experiments are included.

Implicit equal‐weights particle filter
Quarterly Journal of the Royal Meteorological Society, Volume 142, Issue 698, Page 1904-1919, July 2016 Part A., 2016 The physics related to the formation of clouds like the one shown in the image is highly complex and nonlinear. Standard data‐assimilation techniques rely on linearisations and yield low‐quality results when applied to phenomena like this. Fully nonlinear data‐assimilation methods do exist but are typically too computationally expensive for high ...

Journal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full
