Tensor mesons produced in tau lepton decays
, 2011 Light tensor mesons (T = a_2, f_2 and K_2^*) can be produced in decays of tau leptons. In this paper we compute the branching ratios of tau --> T pi nu decays by assuming the dominance of intermediate virtual states to model the form factors involved in ...

Scaling-up climate services with users in Latin America [PDF]
, 2020 Latin America farmers are highly vulnerable to climate variability, with crop losses observed throughout the region on a virtually annual basis. For instance, as indicated by the United Nations’ Food and Agriculture Organization (FAO) and World Food ...

Further remarks on isospin breaking in charmless semileptonic B decays [PDF]
, 1997 We consider the isospin breaking corrections to charmless semileptonic decays of B mesons. Both, the recently measured branching ratios of exclusive decays by the CLEO Collaboration and the end-point reion of the inclusive lepton spectrum in form factor ...

Ontogenetic shifts in wood anatomy and leaf traits in tropical dry forests
New Phytologist, Volume 249, Issue 2, Page 848-859, January 2026.Summary Trees experience changes in environmental conditions and biophysical constraints as they grow that may lead to shifts in functional traits. While ontogenetic shifts in leaf traits are relatively well understood, changes in wood anatomy traits from seedlings to adults are less clear, especially in tropical dry forests where drought strongly ...

Identifiying High Risk Areas of Zika Virus Infection by Meteorological Factors in Columbia [PDF]
, 2019 Background Several Zika virus (ZIKV) outbreaks have occurred since October 2015. Because there is no effective treatment for ZIKV infection, developing an effective surveillance and warning system is currently a high priority to prevent ZIKV infection ...

Coffee crop weeds: refuge and food source for pests’ natural enemies
Revista de Ciencias Agrícolas, 2021 Weeds in coffee crops have diverse ecosystem services, such as sheltering and feeding natural enemies of pest insects. This study aimed to identify the potential of coffee weeds as food and refuge for natural enemies in shaded and sun coffee crops ...
