Groundwater in Germany: challenges, solutions, and the BMBF funding measure LURCH: sustainable groundwater management

Environmental Sciences Europe
Water is fundamental to life and a vital element for sustainable development. In Germany, groundwater systems are increasingly facing challenges due to climate change and competing demands from various sectors, including drinking water supply ...

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Person Tracking

, 2009
One of the most basic building blocks for the understanding of human actions and interactions is the accurate detection and tracking of persons in a scene. In constrained scenarios involving at most one subject, or in situations where persons can be confined to a controlled monitoring space or required to wear markers, sensors, or microphones, these ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

On train track splitting sequences

, 2010
We show that the subsurface projection of a train track splitting sequence is an unparameterized quasi-geodesic in the curve complex of the subsurface. For the proof we introduce induced tracks, efficient position, and wide curves.

Vertical Interaction Between a Driving Wheelset and Track in the Presence of the Rolling Surfaces Harmonic Irregularities

Romanian Journal of Transport Infrastructure, 2020
The driving wheelset is used in railway traction (locomotives, electric trains, trams, etc.) to support part of the weight of the suspended mass and to drive and brake the vehicle.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Graphania mutans (Walker) and Acremonium lolii (Latch) : the relationship between an insect herbivore and a fungal endophyte of perennial ryegrass : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Zoology at Massey University [PDF]

, 1987
In examining the relationship between Graphania mutans (Walker) (Lepidoptera: Noctuidae) and perennial ryegrass infected with the fungal endophyte Acremonium lolii (Latch in press), the biology of G. mutans was investigated.

Generating Compact Geometric Track-Maps for Train Positioning Applications

, 2019
In this paper, we present a method to generate compact geometric track-maps for train-borne localization applications. Therefore, we first give a brief overview on the purpose of track maps in train-positioning applications.

Research on wheel/rail coupled vibration of metro cars

机车电传动, 2022
The wheel/rail coupled vibration modal is an inherent property of the wheel/rail system, and mastering the coupling vibration characteristics between wheel and rail is inevitable and practical to reduce wheel out of round wear and rail corrugation.
