A code arithmetic approach for quaternary code designs and its application to (1/64)th-fractions [PDF]

Annals of Statistics 2012, Vol. 40, No. 6, 3161-3175, 2013
The study of good nonregular fractional factorial designs has received significant attention over the last two decades. Recent research indicates that designs constructed from quaternary codes (QC) are very promising in this regard. The present paper aims at exploring the fundamental structure and developing a theory to characterize the wordlengths and

Influence of a Hydrogen Addition to the Inert Gas and Subsequent Heat Treatments on the Microstructure and Mechanical Properties of Magnesium WE43 Fabricated by PBF‐LB/M

Advanced Engineering Materials, EarlyView.
This article investigates optimal processing conditions for the laser‐based powder bed fusion of WE43. To limit the interaction with remaining oxygen, a 3 vol% hydrogen admixture to the inert gas is investigated. Furthermore, heat treatments are investigated in the range of 250–350 °C for 48 h.

Generalizing Gelatin Methacryloyl Granular Hydrogel Fabrication Using Stable Microgels with Predictable Stiffness

Advanced Healthcare Materials, EarlyView.
Gelatin methacryloyl (GelMA) granular hydrogel scaffolds (GHS) are fabricated using a generalized two‐step photocrosslinking approach to yield stable (non‐dissolving) microgels suitable for in situ covalent assembly under physiological conditions. A phase diagram is developed to define the interplay between individual microgel stability and scaffold ...

Mexican consumers' attitudes toward irradiated and imported apples

Agribusiness, EarlyView.
Abstract This study centers on analyzing Mexican consumers' willingness to pay (WTP) for imported US fresh apples subjected to irradiation, contrasting it with the more prevalent postharvest chemical treatments. We collect data using a survey tool in Qualtrics designed to explore the impact of information dissemination through two distinct narrative ...

Who is willing to pay a premium for leafy greens produced by indoor agriculture? A comparative choice experiment with US consumers

Agribusiness, EarlyView.
Abstract Indoor agriculture (IA) presents a pathway to producing leafy greens more sustainably by strictly controlling the growing environment, increasing the efficiency of water and land resources use, reducing pesticide application, and enhancing quality characteristics.

“Bio‐based Plastic? Hm, I've Never Seen It!”—A mixed‐methods investigation into consumer preferences for different packaging material of fresh apples and tomatoes

Agribusiness, EarlyView.
Abstract Packaging of fresh fruits and vegetables is standard in many grocery stores. This mixed methods study aims to identify the role packaging plays in consumer choice and what packaging material consumers prefer. We analyzed data from quantitative stated preference experiments with a quota sample of 485 consumers living in Germany.

Biosynthesis of Silver Nanoparticles by Aspergillus terreus: Characterization, Optimization, and Biological Activities

Frontiers in Bioengineering and Biotechnology, 2021
In this study, mycelial filtrate of Aspergillus terreus BA6 was used to reduce AgNO3 to form silver nanoparticles (AgNPs). The effect of seven independent variables on the diameter of AgNPs was studied by applying design of experiments (DOE).

Design Selection for Two-Level Multi-Stratum Factorial Experiments Based on Swarm Intelligence Optimization [PDF]

arXiv, 2022
For unstructured experimental units, the minimum aberration due to Fries and Hunter (1980) is a popular criterion for choosing regular fractional factorial designs. Following which, many related studies have focused on multi-stratum factorial designs, in which multiple error terms arise from the complicated structures of experimental units.

Are all meats substitutes? A basket‐and‐expenditure‐based approach

Agribusiness, EarlyView.
Abstract This study examines the relationship among animal‐based meat and plant‐based meat alternatives (PBMAs) using a basket‐and‐expenditure‐based choice experiment. In particular, we examine whether animal‐based meat products are substitutes or complements with PBMAs.
