Two-dimensional cut plan optimization for cutter suction dredgers [PDF]

open access: yes, 2009
Optimal cut plans for cutter suction dredgers aim to maximize operational efficiency. Maximizing operational efficiency involves minimization of stoppage time resulting from non-productive dredger movements.

DRIVE‐SAFE: Data‐Driven Robustness and Informed Validation for Evolving Specifications via Formal Evaluation

open access: yesAdvanced Robotics Research, EarlyView.
DRIVE‐SAFE evaluates learning‐based, black‐box autonomous driving policies against evolving temporal safety requirements using Signal Temporal Logic robustness metrics. It aggregates distributional robustness measures with domain‐informed weights to guide iterative retraining.

Consensus Formation and Change are Enhanced by Neutrality

open access: yesAdvanced Science, EarlyView.
Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

Nesting-Algorithmus für irreguläre einfache Formen auf ebenen Flächenstücken [PDF]

open access: yes, 2012
The leather processing industry requires considerable amounts of leather. The desire from an economic perspective is, that the leather waste is small. In small and medium-sized companies, optimizations are done from people by hand.

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

open access: yesAdvanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Machine Learning for Green Solvents: Assessment, Selection and Substitution

open access: yesAdvanced Science, EarlyView.
Environmental regulations have intensified demand for green solvents, but discovery is limited by Solvent Selection Guides (SSGs) that quantify solvent sustainability. Training a machine learning model on GlaxoSmithKline SSG, a database of sustainability metrics for 10,189 solvents, GreenSolventDB is developed. Integrated with Hansen solubility metrics,

Nested holography

open access: yesPhysical Review D
Recently, we introduced a symmetry on the structure of angular momentum that interchanges internal and external degrees of freedom. The spin-orbit duality is a holographic map that projects a massive theory in four-dimensional flat spacetime onto the three-dimensional

Bald eagle population increase, reproductive success, and nesting habitat in central interior California

open access: yes
Over much of its range, the bald eagle (Haliaeetus leucocephalus) has substantially recovered from declines in the mid–late 1900s, which resulted from habitat loss, human persecution and disturbance, and contamination by the pesticide DDT.

Nesting of green sea turtles (Chelonia mydas) on Tortuguero Beach, Costa Rica [PDF]

open access: yes, 2003
Tortuguero is located on the north eastern shores of Costa Rica. It is the largest and most important Atlantic nesting-site of the endangered Green turtle (Chelonia mydas) in the Western Hemisphere.
