Runoff on rooted trees [PDF]

Journal of Applied Probability, 2019
AbstractWe introduce an idealised model for overland flow generated by rain falling on a hillslope. Our prime motivation is to show how the coalescence of runoff streams promotes the total generation of runoff. We show that, for our model, as the rate of rainfall increases in relation to the soil infiltration rate there is a distinct phase change.

Thermally Drawn Bioelectric Catheters: Enabling Proprioceptive Endovascular Navigation

Advanced Intelligent Systems, EarlyView.
This work introduces a novel bioelectric navigation system eliminates the need for harmful fluoroscopy during endovascular surgeries. A bespoke 16‐electrode catheter is fabricated using rapid thermal drawing and laser micro‐machining. Paired with a real‐time tracking algorithm fusing vascular geometry detection and distance estimation, this technology ...

Objectives and Key Results–Driven Multiagent Framework for Mechanical Design and Simulation

Advanced Intelligent Systems, EarlyView.
Objectives and key results (OKR)‐agent, an OKR‐driven multiagent framework, turns a plain‐language engineering goal into completed mechanical simulations. Three peer agents—supervisor, modeler, and simulator—share a compact board of OKR and coordinate external molecular dynamics (MD) and finite‐element solvers through a standardized tool interface. The

Lost ground, lost value: Investigating the relationship between soil erosion and agricultural land value

American Journal of Agricultural Economics, EarlyView.
Abstract This study examines the impact of soil erosion on agricultural land values in the United States (US) Midwest. Based on a novel county‐level panel data set with information on soil erosion levels and agricultural land values covering five census years (1997, 2002, 2007, 2012, and 2017), we separately investigate the direct effect of two types ...

Dynamics of organic carbon losses by water erosion after biocrust removal

Journal of Hydrology and Hydromechanics, 2014
In arid and semiarid ecosystems, plant interspaces are frequently covered by communities of cyanobacteria, algae, lichens and mosses, known as biocrusts.

The causal effect of agricultural landscape simplification on Germany's grasslands during a compound drought and heatwave in 2018

American Journal of Agricultural Economics, EarlyView.
Abstract Preserving ecosystem services, along with economic and environmental benefits, will require future landscape policies to identify and incorporate relevant landscape features. In this paper, we investigate the causal effect of agricultural landscape simplification on drought‐related grassland damages.

Policy uncertainty shocks and farm investments in Europe: Evidence from a newspaper‐based index

American Journal of Agricultural Economics, EarlyView.
Abstract In order to quantify the impact of agricultural policy uncertainty on European farmers' investment behavior, we construct a newspaper‐based monthly index of European agricultural policy uncertainty from 2013 to 2023. We use 327,224 newspaper articles to assess and compare the trends in policy uncertainty across five top agricultural producers ...

A soil-based approach to rainfall-runoff modelling in ungauged catchments for England and Wales [PDF]

, 2004
Hydrological models are powerful tools for the investigation of many hydrological issues. The historical approach for the development of rainfall-runoff models, with regard to the choice of model structure and the calibration of the free parameters ...

L‐Cysteine and N‐Acetylcysteine Supplementation Improves Clinical Outcome in a Patient With COXPD10

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT MTO1 is a nuclear gene that encodes a mitochondrial protein essential for modifying mitochondrial transfer RNAs (tRNAs) and stabilizing codon‐anticodon interactions to ensure accurate and efficient mitochondrial protein synthesis and oxidative phosphorylation.
