Research outputs 2022 to 2026

Climate change-driven increases in drought risk pose a critical threat to global carbon and water cycles. However, ecosystem-scale responses remain poorly quantified, particularly for severe, multiyear drought events. We addressed this gap by examining ecosystem-scale carbon and water flux sensitivity to the extreme 2018–19 drought in Australia using data from 14 eddy covariance flux sites. The ecosystems span grasslands and semi-arid woodlands to tropical and temperate forests. The driest sites (classed as “grass” and “very dry”) experienced drastic productivity impacts, with a 65% decrease in Gross Primary Productivity (GPP) over 2 years relative to the pre-drought average. However, fluxes in …

The Relationship Between Sleep Quality And Physical Fitness Toward The Menstrual Cycle In High School Students, Surya Adi Saputra, Raja Mohammed Firhan Bin Raja Azidin, Alifia Candra Puriastuti, Dessy Amelia, Zumroh Hasanah, Anggi Renawati

Journal of Asian Midwives (JAM)

Background: Sleep is essential for maintaining physical fitness and overall health, as it helps the body recover from intense physical activity and maintains endurance. Physical fitness is determined by heredity, gender, age, body composition, activity, and exercise. Adequate sleep positively impacts overall health, while poorer sleep can negatively affect the body. Teenagers often prefer excessive screen time and oversleep, which can affect their sleep quality. Physical fitness is related to physical activity, and the more often an individual engages in physical activities, the better their fitness. This condition can also impact reproductive health, as hormonal disorders can affect the menstrual …

A Simple Model Of Spiral Galaxies From Geometric Optics, Bogdan Szafraniec, James N. Blake

Faculty Research, Scholarly, and Creative Activity

We propose a simple model of spiral galaxies based on the interference of gravitational waves. The interference is deduced from geometric optics analysis of the refractive index profiles that mimic the behavior of gravitational potentials −1/r and r². We analyze the refractive index profiles, n(r)² = a + b/r and n(r)² = a + br², because they are realistically shaped and yield closed form solutions. The two profiles yield similar physical results, showing that the physical interpretation is not dependent on the exact details of the profile. The first profile yields trajectories that can …

Faculty Research, Scholarly, and Creative Activity

Processes affecting the transformation of riverine dissolved organic carbon (DOC) across the land-to-ocean aquatic continuum are still poorly constrained in Arctic models, leading to large uncertainties in simulated air–sea CO2 fluxes of the coastal periphery. Here we use the ECCO-Darwin regional configuration of the Southeastern Beaufort Sea to analyze the sensitivity of simulated carbon cycling to (1) the model vertical discretization and (2) different parameterizations of Mackenzie River carbon discharge. We show that riverine DOC lifetime rather than its volume largely modulates Mackenzie River plume air–sea CO2 fluxes, leading to the Southeastern Beaufort Sea (SBS) being either a source (0.03 …

Decentralised Consensus Control Of Hybrid Synchronous Condenser And Grid-Forming Inverter Systems In Renewable-Dominated Low-Inertia Grids, Hamid Soleimani, Asma Aziz, S. M.Muslem Uddin, Mehrdad Ghahramani, Daryoush Habibi

Research outputs 2022 to 2026

The increasing penetration of renewable energy sources (RESs) has significantly altered the operational characteristics of modern power systems, resulting in reduced system inertia and fault current capacity. These developments introduce new challenges for maintaining frequency and voltage stability, particularly in low-inertia grids that are dominated by inverter-based resources (IBRs). This paper presents a hierarchical control framework that integrates synchronous condensers (SCs) and grid-forming (GFM) inverters through a leader–follower consensus control architecture to address these issues. In this approach, selected GFMs act as leaders to restore nominal voltage and frequency, while follower GFMs and SCs collaboratively share active and reactive power. …
