‘Escaping Isn't for Everyone’: Kurdish Smugglers’ Navigational Tactics at Checkpoints in Iran

open access: yesDevelopment and Change, EarlyView.
ABSTRACT This article examines how Kurdish smugglers navigate state and insurgent checkpoints in the borderlands of western Iran. Drawing on ethnographic research, it analyses two key navigational tactics: persin, a form of negotiated passage involving transaction, recognition and the contingent toleration of authority; and jimi, rendered here as ...

Asymptotic behaviour of random tridiagonal Markov chains in biological applications

open access: yes, 2012
Discrete-time discrete-state random Markov chains with a tridiagonal generator are shown to have a random attractor consisting of singleton subsets, essentially a random path, in the simplex of probability vectors.

The Legacy of Policy Inaction in Climate‐Growth Models

open access: yesInternational Economic Review, EarlyView.
ABSTRACT To better understand the structure and core mechanisms of a broad class of climate‐growth models, we study a simplified version of the dynamic integrated model of climate and the economy (DICE) through the lens of growth theory. We analytically show that this model features a continuum of saddle‐point stable steady states.

Upper semicontinuity of attractors of non-autonomous dynamical systems for small perturbations

open access: yesElectronic Journal of Differential Equations, 2002
We study the problem of upper semicontinuity of compact global attractors of non-autonomous dynamical systems for small perturbations. For the general nonautonomous dynamical systems, we give the conditions of upper semicontinuity of attractors for small

Local attractivity in nonautonomous semilinear evolution equations

open access: yesNonautonomous Dynamical Systems, 2014
We study the local attractivity of mild solutions of equations in the form u’(t) = A(t)u(t) + f (t, u(t)), where A(t) are (possible) unbounded linear operators in a Banach space and where f is a (possible) nonlinear mapping.

Collaborative platooning and routing for mixed fleets of electric automated vehicles and conventional trucks

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The application of automated ground vehicles (AGVs) is well‐established in closed environments such as port terminals, while their operation in open areas remains challenging. In this work, we set out to overcome this limitation by introducing platooning as a transfer mode in heterogeneous vehicle networks.

Weak homoclinic solutions of anisotropic discrete nonlinear system with variable exponent

open access: yesNonautonomous Dynamical Systems, 2020
We prove the existence of weak solutions for an anisotropic homoclinic discrete nonlinear system. Suitable Hilbert spaces and norms are constructed. The proof of the main result is based on a minimization method.

Nonuniform Dichotomy Spectrum and Normal Forms for Nonautonomous Differential Systems [PDF]

open access: yes, 2014
The aim of this paper is to study the normal forms of nonautonomous differential systems. For doing so, we first investigate the nonuniform dichotomy spectrum of the linear evolution operators that admit a nonuniform exponential dichotomy, where the ...

Rate-induced tipping and saddle-node bifurcation for quadratic differential equations with nonautonomous asymptotic dynamics [PDF]

open access: yes, 2020
An in-depth analysis of nonautonomous bifurcations of saddle-node type for scalar differential equations $x'=-x^2+q(t)\,x+p(t)$, where $q\colon\R\to\R$ and $p\colon\R\to\R$ are bounded and uniformly continuous, is fundamental to explain the absence ...

Assembly–Energetics–Control (AEC) Design Framework for Rotary DNA Nanomachines

open access: yesChemBioChem, Volume 27, Issue 8, April 2026.
Rotary DNA nanomachine is an emerging research interest using DNA as building blocks to fabricate nature‐mimicking mechanisms. Here, we suggest a three‐dimensional conceptual framework to categorize the existing designs and identify underexplored directions.
