An Estimation of Human‐Error Contributions to Historical Ionospheric Data

Earth and Space Science, Volume 7, Issue 10, October 2020., 2020
Abstract Ground‐based radar sounders are used to characterize the dynamics and chemistry of Earth's upper atmosphere by using measurements of ionospheric peak electron density (NmF2) and its associated altitude (hmF2). Continuous sounder observations of the E and F regions of the ionosphere have been carried out regularly at dozens of stations ...

Shear thickening in concentrated suspensions: phenomenology, mechanisms, and relations to jamming

, 2013
Shear thickening is a type of non-Newtonian behavior in which the stress required to shear a fluid increases faster than linearly with shear rate. Many concentrated suspensions of particles exhibit an especially dramatic version, known as Discontinuous ...

Numerical Simulation of Radio Signal from Extended Air Showers

, 2014
The burst of radio emission by the extensive air shower provides a promising alternative for detecting ultra-high energy cosmic rays.We have developed an independent numerical program to simulate these radio signals.

Hybridisation and Species Boundaries in Eucalypts

Austral Ecology, Volume 51, Issue 1, January 2026.
ABSTRACT We review Jamie (James Barrie) Kirkpatrick's influential studies on eucalypt genecology in the 1970's and the trajectory that this research followed in subsequent decades. We focus on two themes which involve hybridisation and gene flow. The first theme is his work on phantom hybrids, which highlights the challenges in determining the origin ...

Assessment of the agronomic potential of dual‐use winter‐hardy peas in Northern New England: Cold tolerance and production challenges for harvestable cover cropping peas

Agrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract Cover crops play a significant role in improving and maintaining good soil quality. However, there are often some agronomic and cost challenges associated with successfully establishing cover crops. In Northeastern regions of the United States, abiotic stressors such as cold affect and high costs limit uptake of the practice.

Non-thermal emission processes in massive binaries [PDF]

, 2007
In this paper, I present a general discussion of several astrophysical processes likely to play a role in the production of non-thermal emission in massive stars, with emphasis on massive binaries.

Resistance of Oil‐Infused PDMS with Different Macroporosities Against Bacterial Attachment

Advanced Materials Interfaces, Volume 12, Issue 22, November 22, 2025.
In this study, a series of environmentally benign, nonfluorinated liquid paraffin‐infused porous PDMS networks with varying porosities is created. By introducing different homogenous and heterogenous bulk structures and varying interfacial roughness by sugar and salt templating, the role of porosity and oil availability on the resistance against ...

Animal Models of Disc Degeneration Using Puncture Injury: A 20 Year Perspective

JOR SPINE, Volume 8, Issue 3, September 2025.
This review of surgically induced IVD puncture injury animal models presents an evolution over decades to include many variations simulating distinct clinical phenotypes of IVDD, and recommends reporting a common set of injury features to facilitate cross‐study comparison.

Breeding for cold tolerance in common annual legume cover crops

Crop Science, Volume 65, Issue 3, May/June 2025.
Abstract There has been a significant increase in cover crop adoption, with land use nearly doubling over the last decade. Winter legume cover crops provide several ecosystem services, such as weed suppression and reducing soil erosion, while serving as an excellent nitrogen source for subsequent cash crops.

Commodity risk assessment of Populus alba, Populus nigra and Populus tremula plants from the UK

EFSA Journal, Volume 23, Issue 3, March 2025.
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by plants of Populus alba, Populus nigra and ...
