The new very small angle neutron scattering spectrometer at Laboratoire Leon Brillouin

The design and characteristics of the new very small angle neutron scattering spectrometer under construction at the Laboratoire Leon Brillouin is described. Its goal is to extend the range of scattering vectors magnitudes towards 2x10{-4} /A. The unique feature of this new spectrometer is a high resolution two dimensional image plate detector sensitive to neutrons. The wavelength selection is achieved by a double reflection supermirror monochromator and the collimator uses a novel multibeam design

Financing agricultural research and development in rich countries: what's happening and why

Governments around the globe are trimming their support for agricultural R&D, giving greater scrutiny to the support that they do provide, and reforming the public agencies that fund, oversee, and carry out the research. These contemporary developments represent a break from previous patterns, which, since WWII, had seen a significant and steady expansion in the public funds provided for agricultural R&D. The growth rate of private-sector spending on agricultural research has slowed along with the growth of public spending in recent years, but the balance continues to shift toward the private sector. This paper presents a quantitative review of these funding trends and the considerable institutional changes that have accompanied them. We present and discuss new data for 22 OECD countries, provide additional data and institutional details for five of these countries, namely Australia, Netherlands, New Zealand, United Kingdom, and the United States, and conclude the paper with an assessment of these policy developments.Agricultural research., Government spending policy., OECD countries., Australia., Netherlands., New Zealand., United Kingdom., United States., Assessment,

A double supermirror monochromator for neutron instrumentation at LLB

The design and characteristics of a double supermirror monochromator for neutron instrumentation at the Laboratoire Leon Brillouin is described. The aim of this monochromator is to reduce the intense gamma-radiation produced by conventional velocity selectors and to avoid a direct view of the guide while keeping a comparable neutron transmission (higher than 70%). The monochromator offers a continuous choice of wavelength selection in the range 0.5 to 2 nm

Shard polytopes

For any lattice congruence of the weak order on permutations, N. Reading proved that gluing together the cones of the braid fan that belong to the same congruence class defines a complete fan, called a quotient fan, and V. Pilaud and F. Santos showed that it is the normal fan of a polytope, called a quotientope. In this paper, we provide a simpler approach to realize quotient fans based on Minkowski sums of elementary polytopes, called shard polytopes, which have remarkable combinatorial and geometric properties. In contrast to the original construction of quotientopes, this Minkowski sum approach extends to type $B$.Comment: 73 pages, 35 figures; Version 2: minor corrections for final versio

A netnography of emergent ESOL researcher identity and development in a virtual community of practice

For emerging researchers, communities of practice (CoPs) can be a much-needed source of knowledge and support, particularly during a global pandemic. Within this context, a virtual CoP (VCoP) project was initiated for novice researchers in Teaching English to Speakers of Other Languages (TESOL)/Applied Linguistics worldwide to exchange perspectives and academic knowledge. Guided by netnography, our study explores the social, cultural, and professional practices of VCoP through multiple digital sources, such as webinar recordings, Facebook group posts, reflective journal entries, and one-on-one interview. The triangulated data aims to examine the effects of virtual mentorship on the agency, engagement, and identity construction of an emerging researcher. Findings illustrate that a VCoP facilitates international networking, fosters the repositioning of ESOL researcher identity, and promotes agency through virtual mentoring. Specifically, netnography opens a viable avenue for remote data mining in Applied Linguistics research
