Gender-inclusive consumer studies improve cassava breeding in Nigeria

Frontiers in Sociology
Including gender research in cassava breeding makes it easier for farmers to adopt new varieties that meet the specific needs and preferences of both male and female farmers, leading to increased adoption of new varieties, improved productivity, and ...

Disruption of mycorrhizal extraradical mycelium and changes in leaf water status and soil aggregate stability in rootbox-grown trifoliate orange

Frontiers in Microbiology, 2015
Arbuscular mycorrhizas possess well developed extraradical mycelium (ERM) network that enlarge the surrounding soil for better acquisition of water and nutrients, besides soil aggregation. Distinction in ERM functioning was studied under a rootbox system,

Faster RooFitting: Automated parallel calculation of collaborative statistical models [PDF]

EPJ Web of Conferences, 2020
RooFit [1, 2] is the main statistical modeling and fitting package used to extract physical parameters from reduced particle collision data, e.g. the Higgs boson experiments at the LHC [3, 4].

Lag Length Selection and the Construction of Unit Root Tests with Good Size and Power

, 2001
It is widely known that when there are negative moving average errors, a high order augmented autoregression is necessary for unit root tests to have good size, but that information criteria such as the AIC and BIC tend to select a truncation lag that is

The fungal collaboration gradient dominates the root economics space in plants

Science Advances, 2020
Collaboration broadens the “root economics space” ranging from “do-it-yourself” to “outsourcing” to mycorrhizal partners. Plant economics run on carbon and nutrients instead of money.

Root plasticity under abiotic stress

Plant Physiology, 2021
Abiotic stresses increasingly threaten existing ecological and agricultural systems across the globe. Plant roots perceive these stresses in the soil and adapt their architecture accordingly.

Functional Conservation and Divergence of Soybean GmSTOP1 Members in Proton and Aluminum Tolerance

Frontiers in Plant Science, 2018
Proton (H+) and aluminum (Al) rhizotoxicity are two major factors limiting crop production in acid soils. Orthologs of the zinc-finger transcription factor, Sensitive To Proton Rhizotoxicity1 (STOP1), have been found to play an essential role in the ...

Effects of pruning on mineral nutrients and untargeted metabolites in fresh leaves of Camellia sinensis cv. Shuixian

Frontiers in Plant Science, 2022
Pruning is an important strategy for increasing tea production. However, the effects of pruning on tea quality are not well understood. In this study, tea leaves were collected from Wuyi Mountain for both ionomic and metabolomic analyses. A total of 1962

Advantages of the mean absolute error (MAE) over the root mean square error (RMSE) in assessing average model performance

, 2005
The relative abilities of 2, dimensioned statistics — the root-mean-square error (RMSE) and the mean absolute error (MAE) — to describe average model-performance error are examined.
