Heteroclinic orbits and transport in a perturbed integrable Suris map
, 1996 Explicit formulae are given for the saddle connection of an integrable family of standard maps studied by Y. Suris. When the map is perturbed this connection is destroyed, and we use a discrete version of Melnikov's method to give an explicit formula for

Enrichment of Helminth Mitochondrial Genomes From Faecal Samples Using Hybridisation Capture
Molecular Ecology Resources, Volume 25, Issue 8, November 2025.ABSTRACT New approaches are urgently needed to enrich rare or low‐abundant DNA in complex samples. Soil‐transmitted helminths (STHs) inhabit heterogeneous environments, including the gastrointestinal tract of their host as adults and are excreted as eggs and larvae in faeces, complicating our understanding of their biology and the use of genetic tools ...

Gangs, Labor Mobility, and Development
Econometrica, Volume 93, Issue 6, Page 2083-2121, November 2025.We study how criminal organizations affect economic development. We exploit a natural experiment in El Salvador, where these criminal organizations emerged due to an exogenous shift in American immigration policy that led to the deportation of gang leaders from the United States to El Salvador.

Existence of Kink and Antikink Wave Solutions of Singularly Perturbed Modified Gardner Equation
MathematicsIn this paper, the singularly perturbed modified Gardner equation is considered. Firstly, for the unperturbed equation, under certain parameter conditions, we obtain the exact expressions of kink wave solution and antikink wave solution by using the ...

Chaos and Control in Coronary Artery System
Discrete Dynamics in Nature and Society, 2012 Two types of coronary artery system N-type and S-type, are investigated. The threshold conditions for the occurrence of Smale horseshoe chaos are obtained by using Melnikov method.

, 2012 We study the dynamics of a two-degrees-of-freedom (two DOF) nonlinear oscillator representing a quartercar model excited by a road roughness profile. Modelling the road profile by means of a harmonic function we derive the Melnikov criterion for a system
