American Journal of Political Science, EarlyView.
Abstract How can defense alliances reap the efficiency gains of working together when coordination and opportunism costs are high? Although specializing as part of a collective comes with economic and functional benefits, states must bargain over the distribution of those gains and ensure the costs of collective action are minimized.

ENHANCED MULTI-OBJECTIVE GREY WOLF OPTIMIZATION USING ADAPTIVE DIVERSITY TUNING AND LEVY FLIGHTS [PDF]

Carpathian Journal of Electrical Engineering
This study proposes an enhanced Multi-Objective Grey Wolf Optimizer (MOGWO) using adaptive population diversity tuning and levy flight theories (EMOGWO-ADTLF). It addresses the issues of parameter tunning by balancing exploration and exploitation.

Front propagation in reaction-diffusion systems with anomalous diffusion

, 2014
A numerical study of the role of anomalous diffusion in front propagation in reaction-diffusion systems is presented. Three models of anomalous diffusion are considered: fractional diffusion, tempered fractional diffusion, and a model that combines ...

Integration of epigenetics into ecotoxicology: insights and fundamental research needs

Biological Reviews, EarlyView.
ABSTRACT Epigenetics refers to heritable changes in genome function that occur without direct alterations to the DNA sequence. A multitude of environmental contaminants can influence the epigenetic marks of a genome. Changes of epigenetic marks including DNA methylation, histone modifications, and non‐coding RNAs can induce alterations at the gene ...

A series of (un)fortunate events: Commercial bank interest rates and deposit reallocation during the Great Depression in the Netherlands

The Economic History Review, EarlyView.
Abstract During the global economic crisis of 1929–33, deposits in the Dutch commercial banking sector sharply declined as funds shifted to the government‐guaranteed Post Office Savings Bank and other savings institutions. Unlike earlier studies for neighbouring countries, we demonstrate that this shift was driven less by a flight to safety and more by

Lévy-like movement patterns of metastatic cancer cells revealed in microfabricated systems and implicated in vivo

Nature Communications, 2018
Metastatic cancer cells differ from their non-metastatic counterparts not only in terms of molecular composition and genetics, but also by the very strategy they employ for locomotion.

Landau theory of restart transitions

, 2019
We develop a Landau like theory to characterize the phase transitions in resetting systems. Restart can either accelerate or hinder the completion of a first passage process.
