The Association of Pregnancy and Scurvy in Indigenous Women and Their Children From the Late Holocene in California (USA)

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Limited evidence of nutritional deficiencies has been identified in bioarchaeological studies of Native California populations, although isotopic and ethnohistoric research provides evidence of regional, seasonal, and cultural variability in food shortages.

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Microbubble‐Based Ultrasound Contrast Agents in Contrast‐Enhanced Ultrasonography for Managing Portal Hypertension in Cirrhosis

open access: yesPortal Hypertension &Cirrhosis, EarlyView.
As the hepatic venous pressure gradient (HVPG) remains the current gold standard for diagnosing portal hypertension in cirrhosis, its clinical application is limited by invasiveness, high cost, and restricted availability. Given the urgent need for noninvasive techniques to dynamically monitor portal vein pressure (PVP), contrast‐enhanced ...

Host phenology‐driven infestation patterns of the carob moth (Ectomyelois ceratoniae) in Mediterranean walnut orchards: insights from comparison with codling moth (Cydia pomonella)

open access: yesPest Management Science, EarlyView.
In Mediterranean walnut orchards, Ectomyelois ceratoniae replaces Cydia pomonella as the primary pest. Capture peaks between packing tissue brown (PTB) stage and husk dehiscence define a critical window for monitoring and early harvest to prevent kernel infestation.

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Study on changes in egg quality traits and genetic parameters of white leghorn hens from 35 to 100 weeks of age

open access: yesPoultry Science
To enhance production efficiency, the egg industry increasingly extends the laying cycle of hens. However, this extension exacerbates the decline in egg quality during the late laying period.

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

open access: yesSmartBot, EarlyView.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

The Economics of Regulations on Hen Housing in California [PDF]

open access: yes
Beginning January 1, 2015, conventional cage housing for egg-laying hens is scheduled to be prohibited in California. We consider the economic implications of the new hen housing regulations on the California shell egg industry.

Hybrid Multiphoton Lithography Scaffolds for Nanoscale Mechanobiological Assessment in Microscale Bone Models

open access: yesSmall, EarlyView.
This work presents a 3D hybrid tissue scaffold inspired by bone, incorporating collagen, fabricated using multiphoton lithography. The mechanical properties of collagen are tunable, and biodegradation allows for time‐dependent changes in geometry. The results demonstrate enhanced osteogenic differentiation of stem cells in our hybrid scaffolds.
