Scattering of light halo nuclei on heavy target at energies around the Coulomb barrier

EPJ Web of Conferences, 2014
We report here on experiments performed at TRIUMF to study the scattering of the light halo nuclei 11Li on lead at energies below and around the Coulomb barrier.

Consistent and non-consistent deformations of gravitational theories

Journal of High Energy Physics, 2022
We study the internally abelianized version of a range of gravitational theories, written in connection tetrad form, and study the possible interaction terms that can be added to them in a consistent way. We do this for 2+1 and 3+1 dimensional models. In

Magnetic moment measurement in 72Zn using the Transient Field technique and Coulomb excitation in inverse kinematics

EPJ Web of Conferences, 2014
The g factor of the first excited 2+ state of 72Zn has been measured using the Low Velocity Transient Field (LVTF) technique in combination with Coulomb excitation in inverse kinematics.

Diffraction‐Free Natural Optical Skyrmions and Their Subwavelength Confinement Around Vortices

Laser &Photonics Reviews, EarlyView.
ABSTRACT Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has been based on wave engineering and has led so far to idealized waves that, in real settings, eventually diffract.

Process‐Induced Anisotropy and Fracture Behavior of Pellet‐3D Printed PLA and PLA/Flax Biocomposites

Polymer Composites, EarlyView.
Fused Granular Fabrication of PLA and PLA/flax biocomposites, followed by tensile testing and fracture surface analysis to evaluate the effects of raster orientation and layer number on anisotropy and fracture behavior. ABSTRACT Fused granular fabrication (FGF) enables cost‐effective, large‐scale polymer additive manufacturing; however, the mechanical ...

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

3He(α,γ)7Be cross section measured using complementary techniques

EPJ Web of Conferences, 2014
The astrophysical S-factor for the 3He(α,γ)7Be reaction plays an important role in the Solar Standard Model and in the Big Bang Nucleosynthesis scenario. The advances from two recent experiments performed using complementary techniques at center of mass (

Agricultural and environmental drivers of variation in the composition of food crops: A scoping review

PLANTS, PEOPLE, PLANET, EarlyView.
Agricultural management and environmental conditions influence the biochemical composition of food crops; however, the specific drivers of this variation remain insufficiently understood, despite their importance for climate change adaptation and human health.

The dynamic links between product and process innovations and productivity for Colombian manufacturing [PDF]

Applied Economic Analysis
Purpose – This paper aims to examine the interrelation between two innovating strategies (product and process) on total factor productivity (TFP) growth and the dynamic linkages between these strategies, for Colombia. The authors first explore whether ex
