Advanced Science, EarlyView.This study outlines the developmental pipeline of a multiplexed nanozyme‐based lateral flow immunoassay for the purpose of ovarian germ cell tumor detection. It demonstrates the application of a design of experiments optimization approach for nanozyme probe conjugate development.

Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Rice is the main staple food for more than half of the world's population and the income from rice is an essential source for livelihoods of millions of households. We examine whether direct seed in rice production is an adaptation of rice farmers to rainfall changes and farm labor scarcity.

Fisher Information Matrix for Two-way Random e Effects Model with Heteroscedasticity
Revstat Statistical JournalModel specification and selection are important aspects of modeling exercises. In this context, the Fisher Information Matrix (FIM) plays an essential role.

Acta Scientiarum: Animal Sciences, 2011 Assuming that selection in closed herds can promote reduction in additive genetic variance, multiple regression models were used to estimate this change in additive genetic (co)variance component, over the years when the selection was done.

Agribusiness, EarlyView.Abstract This study explores the rent price ratio in agricultural land markets, crucial for evaluating market efficiency, policy needs, and farmer decision‐making. Traditionally, the analyses faced challenges due to the absence of concurrent sale and rent data for the same land, potentially leading to biased results.

Price Premiums for Single‐Name and Compound‐Name Geographical Indications in Swiss Cheese Trade
Agribusiness, EarlyView.ABSTRACT Geographical indications (GIs) have become increasingly important in agri‐food markets, especially in Europe. For Swiss cheese imports and exports, we analyze whether GIs are associated with higher trade prices. We find that price premiums can be obtained for both exports and imports. However, this is only the case for cheeses with single name

Retrieval of among-stand variances from one observation per stand
Journal of Forest Science, 2020 Forest inventories provide predictions of stand means on a routine basis from models with auxiliary variables from remote sensing as predictors and response variables from field data.
