Etching-free dual-lift-off for direct patterning of epitaxial oxide thin films
Although monocrystalline oxide films offer broad functional capabilities, their practical use is hampered by challenges in patterning. Traditional patterning relies on etching, which can be costly and prone to issues like film or substrate damage, under-etching, over-etching, and lateral etching. In this study, we introduce a dual-lift-off method for direct patterning of oxide films, circumventing the etching process and associated issues. Our method involves an initial lift-off of amorphous Sr…

Scale dependence of segregation patterns in the filling of silos
Size segregation in granular flows is a well-known phenomenon: laboratory experiments consistently show that large particles migrate toward silo walls during filling, while smaller particles concentrate near the center. Paradoxically, field observations in large-scale industrial silos often report the opposite pattern, challenging these findings. We demarcate these patterns through a systematic experimental study spanning a range of dimensionless numbers relevant to bidisperse granular flows in…

Expedition & Expansion: Leveraging Semantic Representations for Goal-Directed Exploration in Continuous Cellular Automata
Discovering diverse visual patterns in continuous cellular automata (CA) is challenging due to the vastness and redundancy of high-dimensional behavioral spaces. Traditional exploration methods like Novelty Search (NS) expand locally by mutating known novel solutions but often plateau when local novelty is exhausted, failing to reach distant, unexplored regions. We introduce Expedition and Expansion (E&E), a hybrid strategy where exploration alternates between local novelty-driven expansions an…

Welp.
The toolchain is cursed but I have the Trion devkit talking FMC/APB at 75 MHz to a STM32H750. I can probably push further (maybe 100 MHz PCLK?), this isn't failing timing, but it's good enough for the purpose.

Late February in my (first) freshman year and I am literally flunking out of the University of Michigan’s Residential College because I hated it so I set up a cot in some high school friends' dorm room across campus and didn’t attend any classes so why not hitchhike to Boulder and back over the week-long winter break. Here we are with our thumbs out, beginning our trip on State St. in front of the Michigan Union.
People, Nebraska is fucking cold in February.

Not Here, Go There: Analyzing Redirection Patterns on the Web
URI redirections are integral to web management, supporting structural changes, SEO optimization, and security. However, their complexities affect usability, SEO performance, and digital preservation. This study analyzed 11 million unique redirecting URIs, following redirections up to 10 hops per URI, to uncover patterns and implications of redirection practices. Our findings revealed that 50% of the URIs terminated successfully, while 50% resulted in errors, including 0.06% exceeding 10 hops. …

Analytical Framework for Evaluating Traffic Capacity Impacts of Electric Vehicles' Regenerative Braking Dynamics
Regenerative braking (RB) significantly influences electric vehicle (EV) car-following (CF) dynamics, yet traditional traffic-flow models rarely capture these effects. We introduce a comprehensive empirical dataset comprising 197.5 hours of driving data from 25 drivers across eight EV models to systematically investigate regen-induced CF behaviors. Two primary CF patterns emerge: (i) steady-state scenarios where EVs use regenerative braking and subsequently re-accelerate to equilibrium speeds w…

Change Data Capture is a powerful technique enabling organisations to respond to real-time data changes. At Berlin Buzzwords, Muhammet Orazov explored FlinkCDC, a component of Apache Flink and discussed how it uses Flink's robust stream processing capabilities to provide a CDC pattern.

Since St George was born in Turkey, died in Palestine and never set foot on Britain I find all of his flags going up around the UK a bit strange but am fine with it really. A nice international symbol of unity with all the other countries with him as their patron saint (Aragon, Catalonia, Georgia, Lithuania, Palestine, Portugal, Germany, Greece, Moscow, Istanbul, Genoa and Venice).
My worry is that in a year there will be really tatty flags everywhere, filling the air with microplastic…

that was a really fun night
