Shoot yield drives phosphorus use efficiency in Brassica oleracea and correlates with root architecture traits [PDF]

, 2009
The environmental and financial costs of using inorganic phosphate fertilizers to maintain crop yield and quality are high. Breeding crops that acquire and use phosphorus (P) more efficiently could reduce these costs.

A Python package for fast GPU‐based proton pencil beam dose calculation

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Open‐source GPU‐based Monte Carlo (MC) proton dose calculation algorithms provide high speed and unparalleled accuracy but can be complex to integrate with new applications and remain slower than GPU‐based pencil beam (PB) methods, which sacrifice some physical accuracy for sub‐second plan calculation.

Shooting the Auctioneer [PDF]

, 2006
Most dynamic stochastic general equilibrium models of the macroeconomy assume that labor is traded in a spot market. Two exceptions by David Andolfatto and Monika Merz combine a two-sided search model with a one-sector real business cycle model. These hybrid models are successful, in some dimensions, but they cannot account for observed volatility in ...

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

Advanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

A Screen-Shooting Resilient Document Image Watermarking Scheme using Deep Neural Network [PDF]

arXiv, 2022
With the advent of the screen-reading era, the confidential documents displayed on the screen can be easily captured by a camera without leaving any traces. Thus, this paper proposes a novel screen-shooting resilient watermarking scheme for document image using deep neural network. By applying this scheme, when the watermarked image is displayed on the

Profilometry‐Based Indentation Plastometry Testing of Tungsten at High Temperature

Advanced Engineering Materials, EarlyView.
Profilometry‐based indentation plastometry (PIP) allows extraction of stress‐strain curves from indent profiles. Tungsten is of industrial interest but is brittle at room temperature. It does plastically deform at higher temperatures. Excellent agreement is obtained between the two techniques in this regime, but PIP also gives plasticity ...

A Unified Perspective on Multiple Shooting In Differential Dynamic Programming [PDF]

arXiv, 2023
Differential Dynamic Programming (DDP) is an efficient computational tool for solving nonlinear optimal control problems. It was originally designed as a single shooting method and thus is sensitive to the initial guess supplied. This work considers the extension of DDP to multiple shooting (MS), improving its robustness to initial guesses.
