374 suomalaista kuoli viime vuonna myrkkyyn – nämä aineet korostuvat
Myrkytys on johtanut viime vuosina kuolemaan satoja kertoja. Henkirikoksissa myrkkyä käytetään vain harvoin, Yle listasi tapauksia tältä vuosituhannelta.

Logical Approaches to Non-deterministic Polynomial Time over Semirings
We provide a logical characterization of non-deterministic polynomial time defined by BSS machines over semirings via existential second-order logic interpreted in the semiring semantics developed by Grädel and Tannen. Furthermore, we show that, similarly to the classical setting, the satisfiability problem of propositional logic in the semiring semantics is the canonical complete problem for this version of NP. Eventually, we prove that the true existential first-order theory of the semiring …

Second-timescale Glints from Satellites and Space Debris Detected with Tomo-e Gozen
A search for second-timescale optical transients is one of the frontiers of time-domain astronomy. However, it has been pointed out that reflections of sunlight from Earth-orbiting objects can also produce second-timescale ``glints.'' We conducted wide-field observations at 2 frames per second using Tomo-e Gozen on the 1.05 m Kiso Schmidt telescope. We identified 1554 point-source glints that appeared in only one frame (0.5 sec). Their brightness ranges from 11 to 16 mag, with fainter glints be…

Infinite-Dimensional Stochastic Differential Equations and Diffusion Dynamics of Coulomb Random Point Fields
We consider the stochastic dynamics of infinite particle systems in $\mathbb{R}^d$ interacting through the $d$-dimensional Coulomb potential. For arbitrary inverse temperature $β>0$ and all dimensions $d\ge2$, we construct solutions to the associated infinite-dimensional stochastic differential equations (ISDEs). Our main results establish the existence of strong solutions and their pathwise uniqueness. The resulting labeled process is an $(\mathbb{R}^d)^N$-valued diffusion with no invariant m…
