An exploratory faunal survey of New Zealand temperate rainforest epiphytes
(New Zealand Natural Sciences, 2014-06-01)Epiphyte communities and their corresponding faunal assemblages were quantified on the canopy trees Agathis australis and Metrosideros robusta. A diverse community of native fauna that included invertebrates, reptiles and ... -
A pilot randomised controlled trial of oral doxycycline after endoscopic sinus surgery and its effects on the sinonasal microbiome
(European Rhinologic Society, 2022-04-08)Oral antibiotics are commonly prescribed after endoscopic sinus surgery (ESS) despite minimal clinical data supporting this practice. We aim to assess the effect of post-ESS doxycycline on clinical outcomes and on the ... -
Measures of Dosage for Spinal-Cord Electrical Stimulation: Review and Proposal
(Institute of Electrical and Electronics Engineers (IEEE), 2023)This manuscript proposes an electrical definition of therapeutic dose for spinal cord systems used for the treatment of chronic pain, analogous to the pharmacological definition. Dose-response relationships are fundamental ... -
Limited role of climate change in extreme low rainfall associated with southern Madagascar food insecurity, 2019–21
(IOP Publishing, 2022-12-01)Southern Madagascar recently experienced a severe food security crisis, made significantly worse by well below average rainfall from July 2019 to June 2021. This exceptional drought has affected a region with high pre-existing ... -
Metaheuristics for Discovering Favourable Continuous Intravenous Insulin Rate Protocols from Historical Patient Data
(SPRINGER INTERNATIONAL PUBLISHING AG, 2020-01-01)Metaheuristic search algorithms are used to develop new protocols for optimal intravenous insulin infusion rate recommendations in scenarios involving hospital in-patients with Type 1 Diabetes. Two metaheuristic search ... -
Efficiency enhancement to a linear AC voltage regulator: Multi-winding versus multi-transformer design
(Institute of Electrical and Electronics Engineers (IEEE), 2020-06-18)Electricity distribution companies are required to supply electric power, which conforms to accepted standards, that place limits on voltage fluctuations beyond nominal values. However, it is common for these fluctuations ... -
Metabarcoding inventory of an arctic tundra soil ecosystem reveals highly heterogeneous communities at a small scale
(Springer, 2023-05-01)Biodiversity surveys of Arctic soil ecosystems are limited. Here, we provide a sequence-based inventory of soil fauna from an Arctic tundra ecosystem near the Canadian High Arctic Research Station in Cambridge Bay, Nunavut. ... -
Bio self-healing nanoconcretes
(2019-11-15)Concrete as the most widely used construction material is susceptible to crack when exposes to stresses. Various types of passive techniques have been introduced to fill the generated cracks, however the majority of them ... -
Co-innovation and Integration and Implementation Sciences: Measuring their research impact - examination of five New Zealand primary sector case studies
(Informa UK Limited, 2021-01-01)The Primary Innovation programme investigated co-innovation to solve complex agricultural problems in five New Zealand primary sector projects. The projects engaged diverse stakeholders using a collaborative, integrative ... -
3D-printed polylactide composites reinforced with short lyocell fibres – Enhanced mechanical properties based on bio-inspired fibre fibrillation and post-print annealing
(Elsevier, 2023-09-05)In this study, 3D printable polylactide (PLA) composites reinforced with 10, 20 and 30 mass% of short lyocell fibres were produced by melt compounding PLA modified with maleic anhydride. Based on bio-inspired anchoring ... -
Contrasting hydrodynamic regimes of submerged pinnacle and emergent coral reefs.
(Public Library of Science, 2022-08-12)Hydrodynamics on coral reefs vary with depth, reef morphology and seascape position. Differences in hydrodynamic regimes strongly influence the structure and function of coral reef ecosystems. Submerged coral reefs on ... -
Limiting motorboat noise on coral reefs boosts fish reproductive success.
(2022-05-20)Anthropogenic noise impacts are pervasive across taxa, ecosystems and the world. Here, we experimentally test the hypothesis that protecting vulnerable habitats from noise pollution can improve animal reproductive success. ... -
Grainyhead-like 2 is required for morphological integrity of mouse embryonic stem cells and orderly formation of inner ear-like organoids
(Frontiers Media S.A., 2023-01-01)Mutations in the transcription factor gene grainyhead-like 2 (GRHL2) are associated with progressive non-syndromic sensorineural deafness autosomal dominant type 28 (DFNA28) in humans. Since complete loss of Grhl2 is lethal ... -
Leaf-level coordination principles propagate to the ecosystem scale.
(Nature Research, 2023-07-04)Fundamental axes of variation in plant traits result from trade-offs between costs and benefits of resource-use strategies at the leaf scale. However, it is unclear whether similar trade-offs propagate to the ecosystem ... -
Optimal sample type and number vary in small shallow lakes when targeting non-native fish environmental DNA.
(PeerJ Publishing, 2023-05-02)Non-native fish have been shown to have deleterious impacts on freshwater ecosystems in New Zealand. Early detection is critical for their effective management. Traditional capture-based techniques may not detect newly ... -
The Taupō eruption sequence of AD 232 +- 10 in Aotearoa New Zealand: a retrospection
(Tokyo Geographical Society, 2021-02-25)The Taupō eruption, also known as eruption Y, occurred in late summer to early autumn (typically late March to early April) in AD 232 +- 10 yr at Taupō volcano, an ‘inverse’ caldera volcano underlying Lake Taupō in the ... -
A New Species of Pittosporum Described from the Poor Knights Islands, Northland, Aotearoa/New Zealand
(AMER SOC PLANT TAXONOMISTS, 2018-04-01)Here we describe Pittosporum roimata Gemmill & S.N. Carter, the only vascular plant endemic to the Poor Knights Islands, Northland, Aotearoa/New Zealand. This new species has previously been referred to as a distinct ... -
Finding synaptic couplings from a biophysical model of motor evoked potentials after theta-burst transcranial magnetic stimulation
(Elsevier B.V., 2023-02-15)OBJECTIVE: We aimed to use measured input-output (IO) data to identify the best fitting model for motor evoked potentials. METHODS: We analyzed existing IO data before and after intermittent and continuous theta-burst ... -
Isolation and characterization of soda lignin from OPEFB and evaluation of its performance as wood adhesive
(Elsevier BV, 2023-09)The purpose of this study was to explore the mechanical properties of plywood panels that had been bound with lignin-phenol-formaldehyde (LPF) adhesive. LPF, composed of lignin that was extracted from Oil Palm Empty Fruit ... -
