Confronting Tracker Field Quintessence with Data [PDF]

open access: yes, 2011
We confront tracker field quintessence with observational data. The potentials considered in this paper include $V(\phi)\propto\phi^{-\alpha}$, $\exp(M_{p}/\phi)$, $\exp(M_{p}/\phi)-1$, $\exp(\beta M_{p}/\phi)$ and $\exp(\gamma M_{p}/\phi)-1$; while the data come from the latest SN Ia, CMB and BAO observations.

The combination of a microbial and a non‐microbial biostimulant increases yield in lettuce (Lactuca sativa) under salt stress conditions by up‐regulating cytokinin biosynthesis

open access: yesJournal of Integrative Plant Biology, Volume 66, Issue 10, Page 2140-2157, October 2024.
The combination of a microbial and a non‐microbial biostimulant increased yield of lettuce under salt stress. Application of the non‐microbial biostimulant triggered an abscisic acid‐dependent response and, when applied with the microbial biostimulant, potentiated the responses triggered by the microbial biostimulant and elicited a cytokinin‐dependent ...

Using fusion effects to decrease uncertainty in distance sampling models when collating data from different surveys

open access: yesMarine Mammal Science, Volume 40, Issue 3, July 2024.
Abstract Estimates of population abundance are required to study the impacts of human activities on populations and assess their conservation status. Despite considerable effort to improve data collection, uncertainty around estimates of cetacean densities can remain large.

Update of the Xylella spp. host plant database

open access: yesEFSA Journal, Volume 16, Issue 9, September 2018., 2018
Abstract Following a request from the European Commission, EFSA periodically updates the database on the host plants of Xylella spp. While previous editions of the database (2015 and 2016) dealt with the species Xylella fastidiosa only, this database version addresses the whole genus Xylella, including therefore both species X.
