Universality in nonadiabatic behaviour of classical actions in nonlinear models with separatrix crossings

, 2007
We discuss dynamics of approximate adiabatic invariants in several nonlinear models being related to physics of Bose-Einstein condensates (BEC). We show that nonadiabatic dynamics in Feshbach resonance passage, nonlinear Landau-Zener (NLZ) tunnelling ...

Racism and racial disparities in firearm violence: A scoping review

American Journal of Community Psychology, EarlyView.
Abstract Firearm violence (i.e., interpersonal, police firearm violence) disproportionately affects racially minoritized communities. Researchers recently shifted their focus from race to racism to better understand the factors that contribute to racial disparities in firearm violence.

Joint Time Frequency Analysis Techniques: A study of Transitional Dyamics in Sheet/Cloud Cavitation [PDF]

, 2001
An introduction to, and the use of, Joint Time Frequency Analysis techniques is given. Special emphasis is made on Time Frequency Distribution series. This method is demonstrated on selected experimental data.

B/ordering and healthcare access for migrants with precarious status: The role of healthcare workers in counteracting restrictive policies

American Journal of Community Psychology, EarlyView.
Abstract In Canada, precarious migration is largely invisibilized. Nonetheless, b/ordering greatly affects people's realities by limiting access to social rights. In Quebec, migrants with precarious status (MPS) do not have access to healthcare, although Quebec has a “universal” healthcare coverage.

Fat handles and phase portraits of Non Singular Morse-Smale flows on S^3 with unknotted saddle orbits [PDF]

, 2014
In this paper we build Non-singular Morse-Smale flows on S^3 with unknotted and unlinked saddle orbits by identifying fat round handles along their boundaries. This way of building the flows enables to get their phase portraits.

Real‐World Outcomes of Mycosis Fungoides and Site‐Specific Nodal Involvement: A Registry‐Based Study of 25 467 Patients

American Journal of Hematology, EarlyView.
ABSTRACT Mycosis fungoides (MF) is a rare extranodal T‐cell lymphoma with primary cutaneous involvement. While it is the most common primary skin lymphoma, large‐scale real‐world data defining survival benchmarks and the prognostic significance of specific nodal sites remain limited.

Bifurcations and chaos in a three-dimensional generalized Hénon map

Advances in Difference Equations, 2018
This article presents the bifurcation and chaos phenomenon of the three-dimensional generalized Hénon map. We establish the existence and stability conditions for the fixed points of the system.

Transition From Primary to Secondary School: Igniting Attendance and Engagement Among Aboriginal and Torres Strait Islander Students Through National Policy Reform

Australian Journal of Social Issues, EarlyView.
ABSTRACT Australia's Closing the Gap reform aims to address disparities experienced by Aboriginal and Torres Strait Islander peoples. There are specific targets focussed on key educational transitions; yet, the transition to secondary education is not a targeted priority.

Stability and Phase Portraits for Simple Dynamical Systems

Civil and Environmental Engineering, 2018
In structural dynamics models of mechanical oscillator and vibration analysis are of great importance. In this article motion of mechanical oscillator is modelled using second order linear autonomous differential systems.
