Prototype Analysis in Hopfield Networks With Hebbian Learning.

We discuss prototype formation in the Hopfield network. Typically, Hebbian learning with highly correlated states leads to degraded memory performance. We show that this type of learning can lead to prototype formation, where unlearned states emerge as representatives of large correlated subsets of states, alleviating capacity woes.

Collaborative wildlife disease outbreak investigation and response at Bells Swamp Victoria, February 2023.

In February 2023, a report of morbidity and mortality in waterbirds triggered a collaborative regional wildlife disease outbreak investigation and response, led by Parks Victoria. Triage, rehabilitation and diagnosis of sick and dead birds were undertaken by Zoos Victoria (ZV), Agriculture Victoria, Vets for Compassion, Wildlife Victoria and Melbourne Veterinary School (MVS). The field response focused on collection of sick and dead birds for wildlife welfare, for diagnosis, and to reduce environmental contamination.

A Gaussian-plume based Monte Carlo method for calculating radiation dose in the near field of buildings.

A Monte Carlo (MC) programme was written using the dose point kernel method to calculate doses in the roof zone of a building from nearby releases of radioactive gases. A Gaussian Plume Model (GPM) was parameterised to account for near-field building effects on plume spread and reflection from the roof. Rooftop recirculation zones and building-generated plume spread effects were accounted in a novel Dual Gaussian Plume (DGP) formulation used with the MC model, which allowed for the selection of angle of approach flow, plume release height in relation to the building and position of the release point in relation to the leading edge of the building.

A geospatial analysis of accessibility and availability to implement the primary healthcare roadmap in Ethiopia.

Background: Primary healthcare (PHC) is a crucial strategy for achieving universal health coverage. Ethiopia is working to improve its primary healthcare system through the Optimization of Health Extension Program (OHEP), which aims to increase accessibility, availability and performance of health professionals and services. Measuring current accessibility of healthcare facilities and workforce availability is essential for the success of the OHEP and achieving universal health coverage in the country.

Factors associated with spontaneous vaginal birth in nulliparous women: A descriptive systematic review.

Problem: Spontaneous vaginal birth (SVB) rates for nulliparous women are declining internationally.

Background: There is inadequate understanding of factors affecting this trend overall and limited large-scale responses to improve women's opportunity to birth spontaneously.

Aim: To undertake a descriptive systematic review identifying factors associated with spontaneous vaginal birth at term, in nulliparous women with a singleton pregnancy.
