Analytical solution of stochastic model of risk-spreading with global coupling

open access: yes, 2013
We study a stochastic matrix model to understand the mechanics of risk-spreading (or bet-hedging) by dispersion. Such model has been mostly dealt numerically except for well-mixed case, so far.

Developing a macroecology for human‐altered ecosystems

open access: yesEcography, EarlyView.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

Efficient Implementation and the Product State Representation of Numbers

open access: yes, 2001
The relation between the requirement of efficient implementability and the product state representation of numbers is examined. Numbers are defined to be any model of the axioms of number theory or arithmetic.

Anti‐Globalization Dynamics and Africa's Structural Transformation: Identifying Avoidable Environmental Degradation Thresholds

open access: yesSustainable Development, EarlyView.
ABSTRACT This study pursues a dual objective. First, it investigates the unconditional impact of anti‐globalization on structural transformation in Africa. Second, it explores how environmental degradation interacts with anti‐globalization to influence structural transformation. The analysis focuses on 52 African countries over the period 2005–2023. To

Evolutionary Clustering in Indonesian Ethnic Textile Motifs \ud [PDF]

open access: yes, 2008
The wide varieties of Indonesian textiles could reflect the varsity that has been living with the diversity of Indonesian ethnic groups. Meme as an evolutionary modeling technique promises some conjectures to capture the innovative process of the ...

Reverse Mathematics and parameter-free Transfer

open access: yes, 2018
Recently, conservative extensions of Peano and Heyting arithmetic in the spirit of Nelson's axiomatic approach to Nonstandard Analysis, have been proposed.

Rebound Effects of Digital Textile Microfactories in Fashion, a System Dynamics Study of CO2 Emissions

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT The fashion industry's high resource use and globalised supply chains generate environmental degradation through overproduction, waste and pollution. Digital Textile Microfactories (DTMFs) are promoted as a more sustainable alternative because they enable fast, digitalised and often localised production, but lower costs and a greener image may

Metic: Biodegradable Plastic from Melinjo Starch and Waste Cooking Oil (WCO) as an Alternative Food Packaging

open access: yesBerkala Sainstek
The use of plastic in food packaging and the high amount of plastic waste generated worldwide, including Indonesia, are serious threats to the environment. In addition, synthetic plastics in food packaging can also harm human health.

Reflection groups in hyperbolic spaces and the denominator formula for Lorentzian Kac--Moody Lie algebras

open access: yes, 1995
This is a continuation of our "Lecture on Kac--Moody Lie algebras of the arithmetic type" \cite{25}. We consider hyperbolic (i.e. signature $(n,1)$) integral symmetric bilinear form $S:M\times M \to {\Bbb Z}$ (i.e.

Season and human footprint weaken the negative effect of temperature on the intraspecific metabolic scaling exponent of wild brown trout populations

open access: yesJournal of Animal Ecology, EarlyView.
We apply a new parameterized model through linking metabolic scaling and the maximum entropy theory of ecology to quantify the intraspecific metabolic scaling exponent of brown trout populations and assess the main drivers shaping the exponent. Abstract Metabolic scaling fundamentally sets the pace of life in almost all organisms.
