Nationwide study finds that leaks in natural gas pipelines contribute to hazardous particulate air pollution
In March 2022, 14 residents of a four-story apartment building in Silver Spring, Maryland, were hospitalized when a gas leak from a cut pipeline caused a major explosion. Every year in the United States, there are hundreds of natural gas (or methane) pipeline leaks—caused by corrosion, equipment malfunctions, and construction activities. Methane leaks are not only dangerous; they contribute to air pollution and climate change.

Pipelines for hydrogen transport: A review of integrity and safety challenges
The European Commission highlights hydrogen as an important energy carrier and chemical feedstock that could help decarbonise sectors otherwise deemed hard-to-abate. Europe’s existing natural gas grid is seen as a promising asset to repurpose for the transportation of hydrogen. This technical report provides a literature review of hydrogen's impact on pipeline materials, particularly steel and polymers. Hydrogen is known to reduce the ductility, fracture toughness, and the fatigue crack growt…

CSD Hannover: ALLES BRICHT ZUSAMMEN!!
Heute Morgen fanden sich die Stände aller Parteien (außer von Die Linke und der FDP, da die alles abgebaut haben) zusammengemischt in einem Ball an Pavillion, Klapptischen und Planen wieder, aufgrund des unfassbaren Windes.
Die Tore, einst beschmückt mit schönen Bannern, nun aufgrund von akuter Zerquetschungsgefahr abgebaut da sie mehrfach drohten auf mich zu wehen.
Die Grünen kamen zu spät und versuchten für satte 30 Sekunden…

America’s Gas Pipeline Buildout Is Mainly for Exports—Not Energy Independence – Mother Jones

teaching a transformer net to approximate ray-tracing
input is a sequence of triangle data (limited to 4k triangles), and a sequence of 8x8 radiance pixels representing the camera (limited to 512x512 resolution)
output is a sequence of 8x8 pixels of the rendered scene. training was ~10 days. generation is ~100ms (NVIDIA A100)
the results are pretty good. scaling will be a challenge (since transformers are quadratic in sequence length)

petBrain: A New Pipeline for Amyloid, Tau Tangles and Neurodegeneration Quantification Using PET and MRI
INTRODUCTION: Quantification of amyloid plaques (A), neurofibrillary tangles (T2), and neurodegeneration (N) using PET and MRI is critical for Alzheimer's disease (AD) diagnosis and prognosis. Existing pipelines face limitations regarding processing time, variability in tracer types, and challenges in multimodal integration. METHODS: We developed petBrain, a novel end-to-end processing pipeline for amyloid-PET, tau-PET, and structural MRI. It leverages deep learning-based segmentation, standa…

Adaptive Configuration Selection for Multi-Model Inference Pipelines in Edge Computing
The growing demand for real-time processing tasks is driving the need for multi-model inference pipelines on edge devices. However, cost-effectively deploying these pipelines while optimizing Quality of Service (QoS) and costs poses significant challenges. Existing solutions often neglect device resource constraints, focusing mainly on inference accuracy and cost efficiency. To address this, we develop a framework for configuring multi-model inference pipelines. Specifically: 1) We model the de…

The only Class 0 Flower snark is the smallest
Graph pebbling is a game played on graphs with pebbles on their vertices. A pebbling move removes two pebbles from one vertex and places one pebble on an adjacent vertex. The pebbling number is the smallest $t$ so that from any initial configuration of $t$ pebbles it is possible, after a sequence of pebbling moves, to place a pebble on any given target vertex. Graphs whose pebbling number is equal to the number of vertices are called Class~$0$ and provide a challenging set of graphs that resist…

Im Grund haben wir es hier in Bad Schwalbach echt schön (schöner als in Wiesbaden, wenn ihr mich fragt), mit dem Kurpark direkt vor der Tür. Nur wärmer dürfte es heute sein.
