Strategies for Navigating Magnetic Microrobots in Neurovascular Networks: A Numerical Analysis. [PDF]
Small SciNavigation of microrobots within vascular structures is key for targeted drug delivery. This work discusses strategies for navigating microrobots through a patient‐specific neurovascular network using magnetic gradients. These strategies and the equations developed for predicting the required magnetic gradients based on microrobot diameter are ...

A Framework for Algae Modeling in Regulatory Risk Assessment
Environmental Toxicology and Chemistry, Volume 42, Issue 8, Page 1823-1838, August 2023., 2023 Abstract The use of toxicokinetic–toxicodynamic (TKTD) modeling in regulatory risk assessment of plant protection products is increasingly popular, especially since the 2018 European Food Safety Authority (EFSA) opinion on TKTD modeling announced that several established models are ready for use in risk assessment.

Forming regional soil carbon networks to support effective climate change solutions
Soil Science Society of America Journal, Volume 87, Issue 4, Page 755-766, July/August 2023., 2023 Abstract Sequestration and storage of organic carbon (C) in soil is an essential component of climate change mitigation and fundamental in promoting the health and climate resilience of soils. Sources of available soil C data are increasing, which complicates efforts to consolidate the data in forms that can be readily used by stakeholders. Spatial and

The Future of Soils in the Midwestern United States
Earth's Future, Volume 11, Issue 5, May 2023., 2023 Abstract Soil is the source of the vast majority of food consumed on Earth, and soils constitute the largest terrestrial carbon pool. Soil erosion associated with agriculture reduces crop productivity, and the redistribution of soil organic carbon (SOC) by erosion has potential to influence the global carbon cycle.

EVASION: Prison Escapes and the Predicament of Incarceration in Rio de Janeiro
Cultural Anthropology, Volume 38, Issue 1, Page 36-59, February 2023., 2023 ABSTRACT This article examines Brazil's project of incarceration through the figure of evasion (evasão)—the act of escaping prison custody, often temporarily. Evasion traces a path across the borders of captivity and freedom, as people routinely flee confinement, only to return of their own accord.

Magnetic Resonance in Medicine, Volume 88, Issue 4, Page 1643-1658, October 2022., 2022 Purpose Dual‐velocity encoded (dual‐venc or DV) 4D flow MRI achieves wide velocity dynamic range and velocity‐to‐noise ratio (VNR), enabling accurate neurovascular flow characterization. To reduce scan time, we present interleaved dual‐venc 4D Flow with independently prescribed, prospectively undersampled spatial resolution of the high‐venc (HV ...
