New Limits on Light Hidden Sectors from Fixed-Target Experiments [PDF]

open access: yes, 2015
New physics can be light if it is hidden, coupling very weakly to the Standard Model. In this work we investigate the discovery prospects of Abelian hidden sectors in lower-energy fixed-target and high-precision experiments.

To spray or not to spray?

open access: yesASCILITE Publications, 2009
A scenario-based exercise was developed to expose third-year degree-level horticultural students to the complexities of modern orchard pest and disease management. Using scenarios developed and presented with the e-learning tool SBL Interactive, students are required to analyze four successive scenarios set at different growth stages in the crop, and ...

Multi-Exposure PIV Measurements of Velocity Fields in Sprays [PDF]

open access: yesMATEC Web of Conferences, 2022
This paper presents an approach to the use of the PIV method in the diagnosis of sprays generated by an effervescent atomiser. Due to the different density of the liquid phase depending on the distance from the nozzle, problems arise with the correct ...

Low-Temperature Enhancement of Semi-annihilation and the AMS-02 Positron Anomaly [PDF]

open access: yes, 2018
Semi-annihilation is a generic feature of particle dark matter that is most easily probed by cosmic ray experiments. We explore models where the semi-annihilation cross section is enhanced at late times and low temperatures by the presence of an s ...

Proactive control of cresting in homogeneous oil reservoirs: an experimental study

open access: yesPetroleum Science, 2017
This paper sets out to investigate experimentally the use of electromagnetic valves in controlling production of water during cresting from homogeneous non-fractured thick-oil and thin-oil reservoirs, based on the principle of capillarity and ...

Evaluation of Calcium Application Methods on Delaying Plant Wilting under Water Deficit in Bedding Plants

open access: yesAgronomy, 2021
Floriculture crops can lose their aesthetic quality due to water deficit during postproduction. Calcium is a secondary messenger in plant stress signaling, and the treatment of calcium has been proposed to alleviate damage by various abiotic stresses ...

Four boosted tops from a Regge gluon

open access: yes, 2011
The hierarchy problem can by addressed by extending the four-dimensional space-time to include an extra compact spatial dimension with non-trivial "warped" metric, as first suggested by Randall and Sundrum. If the Randall-Sundrum framework is realized in
