Feasibility study of a mission to Sedna -- Nuclear propulsion and advanced solar sailing concepts.
TL;DR: Solar sails could make the trip take some 7 years, while thermonuclear fusion could take 10 years. Whereas with current engines it would take 30 years.

Feasibility study of a mission to Sedna -- Nuclear propulsion and advanced solar sailing concepts
Exploring the outer reaches of the Solar System presents significant propulsion and mission design challenges. This study assesses the feasibility of a mission to Sedna using two advanced propulsion concepts: the Direct Fusion Drive (DFD) rocket engine, based on D-$^{3}$He thermonuclear fusion, and a solar sail utilizing thermal desorption of its coating for propulsion. Both are evaluated for a one-way Earth-to-Sedna mission; however, due to the different performances the DFD would enable orbit…

On the Feasibility of Distributed Phase Synchronization for Coherent Signal Superposition
In this study, we analyze the feasibility of distributed phase synchronization for coherent signal superposition, a fundamental enabler for paradigms such as coherent over-the-air computation (OAC), distributed beamforming, and interference alignment, under mobility and hardware impairments. With the focus on coherent OAC, we introduce phase-coded pilots (PCPs), a strategy where the radios communicate with each other to eliminate the round-trip phase change in the uplink (UL) and downlink (DL) …

On the Feasibility of Poisoning Text-to-Image AI Models via Adversarial Mislabeling
Today's text-to-image generative models are trained on millions of images sourced from the Internet, each paired with a detailed caption produced by Vision-Language Models (VLMs). This part of the training pipeline is critical for supplying the models with large volumes of high-quality image-caption pairs during training. However, recent work suggests that VLMs are vulnerable to stealthy adversarial attacks, where adversarial perturbations are added to images to mislead the VLMs into producing …

Mädchen können kein Fußball spielen - hier anschauen
Dokumentarfilm Deutschland 2025 +++ Als Frauenfußball noch verboten war, schrieben mutige Spielerinnen in Ost und West Geschichte. Sie trotzten Verboten und Vorurteilen – und setzten sich durch. Der neue Dokumentarfilm von Torsten Körner erzählt von Pionierinnen wie Anne Trabant-Haarbach und Bärbel Wohlleben, die gegen den DFB, gesellschaftliche Normen und männliche Skepsis kämpften. In der BRD verboten, in der DDR belächelt – doch sie spielten, gründeten Teams und forderten Anerken…

On the Feasibility of Deduplicating Compiler Bugs with Bisection
Random testing has proven to be an effective technique for compiler validation. However, the debugging of bugs identified through random testing presents a significant challenge due to the frequent occurrence of duplicate test programs that expose identical compiler bugs. The process to identify duplicates is a practical research problem known as bug deduplication. Prior methodologies for compiler bug deduplication primarily rely on program analysis to extract bug-related features for duplicate…

In it, US Army Core of Engineers looks at seawalls and similar to mitigate coastal storm surge risk in the #NYC metro
Public comment period July 24, 2025 – August 25, 2025
There are 3 spots of actionable items (FY2028 cost, added value):
1) East Harlem (cost $762million, $1.264 billion)
2) East Riser Meadowlands (cost $249million, value added $428 million)
3) Oakwood Beach Staten Island (cost $55million, value added $87 million)
I only know item 1 well enough to comment.

Feasibility of spectral-element modeling of wave propagation through the anatomy of marine mammals
This study introduces the first 3D spectral-element method (SEM) simulation of ultrasonic wave propagation in a bottlenose dolphin (Tursiops truncatus) head. Unlike traditional finite-element methods (FEM), which struggle with high-frequency simulations due to costly linear-system inversions and slower convergence, SEM offers exponential convergence and efficient parallel computation. Using Computed Tomography (CT) scan data, we developed a detailed hexahedral mesh capturing complex anatomical …
