Classification of global phase portraits and bifurcation diagrams of Hamiltonian systems with rational potential

Journal of Differential Equations, 2016
The authors find all possible phase portraits, up to topological equivalence, of vector fields of the form \(\dot x = H_y\), \(\dot y = -H_x\), where the Hamiltonian has the form \(H = \frac12 y^2 + P(x) / Q(x)\) and \(P\) and \(Q\) are polynomials of degree at most two.

Caregiver Reports on the Needs and Experiences of Children Impacted by Parental Incarceration: Results From an Australian Survey

Australian Journal of Social Issues, EarlyView.
ABSTRACT Children experiencing parental imprisonment are known to be among the most overlooked in our community. They often experience multiple and compounding disadvantages, with long‐term consequences, but receive no specialised assistance. Knowledge about these children and their families is lacking in Australia and is required to inform policy ...

Australian Activists as Storytellers in Digital Spaces: Acquiring Skills, Producing Content and Getting the Message Out

Australian Journal of Social Issues, EarlyView.
ABSTRACT As modes of activism rapidly evolve, activists—both seasoned and emerging—must increasingly navigate a hybrid terrain of both digital and non‐digital engagement. This paper draws on the personal narratives of 16 nascent activists based in Australia to explore how they develop competencies related to digital storytelling, which is critical to ...

On‐Surface Friedel–Crafts Alkylation Through a Stabilized Intermediate Complex

Angewandte Chemie International Edition, EarlyView.
On‐surface Friedel–Crafts alkylation is demonstrated on Ag(111) at the single‐molecule level. STM, XPS, and DFT calculations uncover the reaction mechanism and explain the stabilization of the key intermediate, providing insight into noble‐metal‐surface‐mediated Csp3${\rm C}_{sp^{3}}$─Csp2${\rm C}_{sp^{2}}$ coupling. ABSTRACT The incorporation of sp3${\

MHD Maxwell Hybrid Nanofluid Transport Featuring Solar Radiation and Thermo‐Diffusive Impacts Over a Permeable Slanted Stretching Sheet

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Hybrid nanofluids have emerged as next‐generation working fluids for advanced engineering application due to their superior heat transport capability in relation to the conventional nanofluids. Motivated by the rising demand for accurate prediction of transport phenomena under realistic operating situations, the present study examines the ...
