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

Development 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 ...

The Legacy of Policy Inaction in Climate‐Growth Models

International 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.

A Lyapunov function for pullback attractors of nonautonomous differential equations

Electronic Journal of Differential Equations, 2000
The contruction of a Lyapunov function characterizing the pullback attractor of a cocycle dynamical system is presented. This system is the state space component of a skew-product flow generated by a nonautonomous differential equation that is driven by ...

Existence and Uniqueness of Solution for Perturbed Nonautonomous Systems with Nonuniform Exponential Dichotomy

Abstract and Applied Analysis, 2014
Nonuniform exponential dichotomy has been investigated extensively. The essential condition of these previous results is based on the assumption that the nonlinear term satisfies |f(t,x)|≤μe−ε|t|. However, this condition is very restricted. There are few

Impulsive Synchronization of Nonautonomous Chaotic Systems

Acta Physica Sinica, 2000
In this paper-the practical stability of impulsive synchronization between two-nonautonomous chaotic systems is studied. This practical stability is equivalent to that of the origin of the synchronization error system. We present the crite ria for the practical stability of the origin of the synchronization error syste m based on the theory of ...

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

International 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.

Positive Periodic Solutions of an Epidemic Model with Seasonality

The Scientific World Journal, 2013
An SEI autonomous model with logistic growth rate and its corresponding nonautonomous model are investigated. For the autonomous case, we give the attractive regions of equilibria and perform some numerical simulations.

Smart Cities, Urban Transportation and Air Quality: A Decade of Literature on Italian Largest Cities

Journal of Economic Surveys, EarlyView.
ABSTRACT Traffic congestion and its associated negative impacts on economic performance and environmental sustainability, particularly air quality, have long plagued urban centers. This article reviews the technologies and policies adopted by major Italian cities to address these issues, focusing on interventions from 2014 to 2024. Through a keyword co‐

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

, 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 ...

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

ChemBioChem, 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.
