Ilford HP5 Plus 400 (6x6)

English Alt Text:
A black and white photo captures a city street running beneath a low overpass with a clearance sign reading “2.5m.” Two people ride bicycles or electric scooters—one holds an umbrella while moving. A car travels alongside them. The overpass has a stone wall and metal railings. In the distance, tall buildings and construction cranes suggest ongoing urban development. The monochrome tone adds a timeless, documentary feel. The scene reflects everyday ci…

A contemplative black and white image shows a person standing at a crosswalk beneath an overpass. The person faces away from the camera, hands clasped behind their back, wearing a jacket. Shadows from the bridge create dramatic contrast on the pavement. In the background, several pedestrians and cars move through the urban setting. The photo evokes solitude and reflection, with strong light and shadow interplay.

A black and white photo of a modern building interior with a high, angled glass ceiling supported by geometric beams. Natural light floods the space. On a mezzanine level, people sit at round tables, possibly in a café or lounge. The word “PURE” is visible on the right wall. Through the large windows, tall buildings suggest an urban setting. The architectural design and relaxed atmosphere contrast with the city outside.

A black and white photo of a quiet bus stop beside a multi-lane road. The bus stop sign features Chinese characters and an information board mounted on a tall pole. A white metal fence lines the road, with trees and a wall in the background. No vehicles or people are visible. Sunlight casts shadows on the sidewalk, adding depth. The grainy texture and monochrome palette give the image a nostalgic, historical feel.

Aurora as seen from Florida

Image of a planet sized rainbow shooting off from the southern hemisphere of Earth showing a grey cat wearing beauty pageant sash and a tiara riding on top of a flying saucer to the end of said rainbow, which leads to a wormhole in space. A street sign in the middle of the rainbow says it's International Drive and Rainbow Drive, while rainbow & heart shaped bubbles float in space nearby. Oh, there's also fireworks the size of North America exploding above Earth while the Tardis and USS Enterpri…

An international group is organizing an observing campaign through the Citizen Science Working Group of the #LUMIO mission: LUMIO is an ESA space mission to observe lunar #impact flashes (LIFs) from space, on the lunar far side (#Geminid meteoroid stream, 13-15 Dec 2025. During the maximum of the stream, the number of visible impact flashes will be higher than during non-shower times, therefore there is a good chance of detecting at least some impact flashes.
Observations can be made using moderately-sized telescopes and a video camera. On the website https://lif.mi.imati.cnr.it/home_page.php there are now a recording of a thorough talk about the project and its slides at https://lif.mi.imati.cnr.it/open_item_page.php?item_idk=LDB-000000001 and slides about the preferred analysis software ALFI at https://lif.mi.imati.cnr.it/open_item_page.php?item_idk=LDB-000000002 -if you want to join in the LGC please sign on by 21 November.

The Turán and Delsarte problems and their duals
We study two optimization problems for positive definite functions on Euclidean space with restrictions on their support and sign: the Turan problem and the Delsarte problem. These problems have been studied also for their connections to geometric problems of tiling and packing. In the finite group setting the weak and strong linear duality for these problems are automatic. We prove these properties in the continuous setting. We also show the existence of extremizers for these problems and thei…

Bounds on the equation of state of cold nuclear matter from imaginary chemical potentials
The sign problem in numerical calculations of the QCD Euclidean space path integral of QCD with a chemical potential vanishes if the chemical potential is imaginary and calculations of the partition function with an imaginary chemical potentials are equivalent to calculations with Lagrange multipliers enforcing the current density. At zero temperature, Lorentz boosts allows one to deduce properties of systems with both number density and and current density from properties of systems with a cur…

Double signs of Hamiltonian circles in doubly signed complete graphs

Double signs of Hamiltonian circles in doubly signed complete graphs
We study Hamiltonian circles in the doubly signed complete graph $Σ_n = (K_n, σ, \mathbb{F}_2^2)$. A circle's double sign is defined as the sum of its edge labels. I establish conditions under which Hamiltonian circles realize all four possible double signs and prove that this occurs when the set of triangle double signs contains at least three distinct values. The proof is based on an analysis of triangle bases of the binary cycle space, structural properties of $K_4$ subgraphs, and explicit…

Combining complex Langevin dynamics with score-based and energy-based diffusion models
Theories with a sign problem due to a complex action or Boltzmann weight can sometimes be numerically solved using a stochastic process in the complexified configuration space. However, the probability distribution effectively sampled by this complex Langevin process is not known a priori and notoriously hard to understand. In generative AI, diffusion models can learn distributions, or their log derivatives, from data. We explore the ability of diffusion models to learn the distributions sample…
