Hydration Behavior of Tricalcium Silicate in Seawater Relevant Salt Systems: A Hybrid Study with the Aid of Machine Learning

Advanced Intelligent Discovery, EarlyView.
The hydration behavior of C3S in seawater‐relevant solutions is studied based on experiments, boundary nucleation and growth (BNG) modeling, and machine learning. The main ions included in seawater modify hydration mechanisms, with MgCl2 showing the strongest acceleration effect at the same concentration.

Human‐in‐the‐Loop Swarms: A Bionic Swarm Approach to Real‐World Soil Mapping

Advanced Intelligent Systems, EarlyView.
This article introduces the “Bionic Swarm,” a novel system that lowers the barriers to real‐world swarm validation by abstracting difficult hardware tasks to app‐guided human agents. We demonstrate the system's utility through the experimental validation of a geotechnical soil‐mapping swarm algorithm and show superior performance to baseline approaches

Food insecurity and unemployment among immigrants in the United States

American Journal of Agricultural Economics, EarlyView.
Abstract Immigrants can be more vulnerable to economic downturns and, during periods of economic hardship, more likely to experience food insecurity compared to natives. This study examines the differential effect of the unemployment rate on the probability of being food insecure among diverse groups of immigrant households relative to natives in the ...

Response of differently adapted populations of blue panic grass (Panicum antidotale Retz.) to water defi cit conditions

Journal of Applied Botany and Food Quality, 2012
To explore plant species that could tolerate harsh environment, six ecotypes of Panicum antidotale were collected from different habitats varying in water availability, salt content and agricultural practices within the Faisalabad city.

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

American Journal of Botany, EarlyView.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Relationship of Relative Leaf Growth Rate to Net Assimilation Rate and its Relevance to the Physiological Analysis of Plant Yield [PDF]

Nature, 1963
IN the growing plant, where the photosynthetic tissues make the major contribution to dry-matter production, the absolute growth rate at any time is the product of the rate of increase in weight per unit of leaf (net assimilation rate1, N.A.R.) and the amount of leaf present.

The rain feels different under the same umbrella: Experiences with poverty across LGBTQ subgroups

American Journal of Community Psychology, EarlyView.
Abstract Population‐based survey data have demonstrated that LGBTQ communities report varying rates of economic insecurity, yet very little research directly assesses how pathways into and experiences with poverty look different among subgroups at the intersections of sexual orientation and gender identity (SOGI).

Facilitators’ champion behaviors for delivering an evidence‐based parenting program

American Journal of Community Psychology, EarlyView.
Abstract Effective implementation of parenting programs relies on multiple factors, particularly the role of facilitators who actively deliver and support the intervention. Facilitators’ champion behaviors or the efforts they make to encourage implementation, can positively impact the outcomes of these programs.

Building Community Amidst the Institutional Whiteness of Graduate Study: Black Joy and Maroon Moves in an Academic Marronage

Australian Journal of Social Issues, EarlyView.
ABSTRACT This article reflects on the construction of a supportive community of Black Afro‐diasporic graduate students and their supervisors researching issues relating to race in the field of education in Australia. It draws on the concept of marronage—a term rooted in the fugitive act of becoming a maroon, where enslaved people enacted an escape in ...
