Cosmological simulations of the same spiral galaxy: satellite properties, the role of baryonic physics and star formation history in shaping dark matter cores/cusps
We investigate the role of baryonic physics in shaping the population, structure, and internal dynamics of galactic subhalos using the Mochima suite of cosmological zoom-in simulations. A refined method is developed to identify bound subhalo material by isolating the local gravitational potential and applying multi-criteria phase-space selection. This approach enables a robust characterisation of subhalo properties across five baryonic runs with varying prescriptions for star formation, and sup…

FlexEmu: Towards Flexible MCU Peripheral Emulation (Extended Version)
Microcontroller units (MCUs) are widely used in embedded devices due to their low power consumption and cost-effectiveness. MCU firmware controls these devices and is vital to the security of embedded systems. However, performing dynamic security analyses for MCU firmware has remained challenging due to the lack of usable execution environments -- existing dynamic analyses cannot run on physical devices (e.g., insufficient computational resources), while building emulators is costly due to the …

Lighthill's mechanism and vorticity cascade in the logarithmic layer of wall turbulence
We investigate Lighthill's proposed turbulent mechanism for near-wall concentration of spanwise vorticity by calculating mean flows conditioned on motion away from or toward the wall in an $Re_τ=1000$ database of plane-parallel channel flow. Our results corroborate Lighthill's proposal throughout the entire logarithmic layer, but extended by counterflows that help explain anti-correlation of vorticity transport by advection and by stretching/tilting. We present evidence also for Lighthill's hy…

I love arguing with a dude who is telling me the device I sell can be found for 1/8th the price, twice now, with no links or other info to back up his claim.
I'm really close to the 2.6x cost of goods with a little extra to cover shipping materials, support, and custom programming that is offered...
And if so, why doesn't he just buy the competitor's product instead of bugging me?

@… As others have mentioned, there are a few options for reasonably well supported static site generators. Hugo, Jekyll, 11ty, Gatsby, take your pick.
Any of them will let you write in Markdown and spit out all the static files to host it somewhere.
For a fairly simple blog, the cost and complexity savings of just generating static pages feels like the ri…

Dataset and Benchmark for Enhancing Critical Retained Foreign Object Detection
Critical retained foreign objects (RFOs), including surgical instruments like sponges and needles, pose serious patient safety risks and carry significant financial and legal implications for healthcare institutions. Detecting critical RFOs using artificial intelligence remains challenging due to their rarity and the limited availability of chest X-ray datasets that specifically feature critical RFOs cases. Existing datasets only contain non-critical RFOs, like necklace or zipper, further limit…

PULSE-A Mission Overview: Optical Communications for Undergraduate Students
Recent advances in the size, weight, and power (SWaP) requirements for space-based sensing have dramatically increased the demand for high-bandwidth downlink. However, high data rate RF transceivers still pose significant SWaP and cost restrictions, especially for university-class CubeSat missions. Optical communication may provide a solution to this challenge, enabling data transmission with order-of-magnitude rate increases over RF while being both secure and SWaP-efficient. The Polarization-…

Deforestation is killing people by raising local temperatures
For decades, the case for saving tropical forests has been cast in terms of carbon. Trees sequester vast quantities of it; razing them pumps more into the air. But new research reminds us that the destruction of rainforests has consequences that arrive long before the carbon accounting is tallied: It makes people hotter, sometimes lethally […]
