Revealing transversity GPDs through the photoproduction of a photon and a ρ meson

EPJ Web of Conferences, 2016
Photoproduction of a pair of particles with large invariant mass is a natural extension of collinear QCD factorization theorems which have been much studied for deeply virtual Compton scattering and deeply virtual meson production.

Decaimiento no leptónico del mesón Bc considerando mesones excitados radialmente en el estado final

Iteckne, 2013
En el presente trabajo se muestra parte del estudio del decaimiento no leptónico del mesón Bc, considerado un mesón pseudoescalar o vectorial excitado radialmente (n = 2) en el estado final, se asume la hipótesis de factorización y utiliza el modelo de ...

Status of ash (Fraxinus spp.) in mixed hardwood post‐outbreak forests near the epicentre of the emerald ash borer invasion

Agricultural and Forest Entomology, EarlyView.
The persistence and health of ash populations were characterized in post‐outbreak forests near the epicentre of the emerald ash borer (EAB) invasion in North America. Regenerating ash remained abundant, but densities of understory ash were higher in wetlands (hydric), while ash remained at the seedling stage in riparian (mesic) and upland (xeric ...

Comprehensive framework for assessing and optimizing existing research networks

Conservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Threat Integration Model for Sagebrush (TIMS): A framework for using spatial decision support tools for strategic management of invasive annual grasses and conifers in sagebrush ecosystems

Conservation Science and Practice, EarlyView.
The Threat Integration Model for Sagebrush (TIMS) combines multiple spatial decision support tools to provide a unified, actionable map of sagebrush ecosystem conditions across the western United States. TIMS improves upon existing tools by including multiple threats in the same map (invasive annual grass [IAG] and conifer encroachment), characterizing

On Meson Masses

Few-Body Systems, 2007
It is shown that in the framework of analytical confinement, when quark and gluon propagators are induced by an vacuum selfdual gluon field with constant strength, the masses of meson with quantum numbers $Q=J^P$ and quark constituents $m_1,~m_2$ are described with reasonable accuracy by the formula $$ M_Q(m_1,m_2)=(m_1+m_2)[1+{A_Q\over (m_1^2+1 ...

Social bees can enhance the persistence of plant–bee interactions during seasonal changes in seasonally dry tropical forests

Ecological Entomology, EarlyView.
Social bees, especially Meliponini, formed a persistent core that maintained plant–bee interactions across both dry and green seasons in the Caatinga. Persistence was not linked to broader diets; social bees used fewer plant species, despite availability, indicating selective tracking of temporally concentrated floral resources.

A Possibility of pi^- Meson Production by a Low Energy Electron Bunch and Positive Ion Bunch

, 1994
"A low energy electron beam (leq1200 eV) is injected perpendicularly to a uniform magnetic field, together with a low energy positive ion beam which is stopped electrically.

The former distribution of White‐tailed Eagles in Iberia, the Mediterranean and the Middle East: a case study of the importance of understanding historical distribution in informing current conservation and restoration interventions

Ibis, EarlyView.
The importance of considering historical data in developing conservation and restoration measures for individual species and for wider ecological restoration has been pointed out by recent reviews but often remains neglected in practice. This paper provides a case study illustrating the issue through a review of the former breeding distribution of the ...

Chinese University Students’ Motivation to Learn Greek: A Transnational Postdigital Exploration

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Research on the motivation of learners of Languages Other Than English (LOTE) has grown steadily in recent years; however, most studies focus on classroom‐based activities and seldom consider how transnational experiences or digital practices contribute to motivational development.
