Winchcombe #meteorite, recovered from a driveway in Gloucestershire, England in 2021 has a complicated history | Eos | #geology

A Splashy Meteorite Was Forged in Multiple Collisions
The Winchcombe meteorite was recovered, largely from a driveway, just hours after it fell to Earth, preserving evidence that its early relatives could have filled Earth’s oceans.

windsurfers: Windsurfers network (1986)
A network of interpersonal contacts among windsurfers in southern California during the Fall of 1986. The edge weights indicate the perception of social affiliations majored by the tasks in which each individual was asked​ to sort cards with other surfer’s name in the order of closeness.
This network has 43 nodes and 336 edges.

On the block size spectrum of the multiplicative Beta coalescent
In this work we introduce the (exchangeable, but non-consistent) multiplicative $Λ$-coalescent, which accounts for the connected components (blocks) of the dynamic $Λ$-random graph. This is the random graph analogue of the classical $Λ$-coalescent studied in mathematical population genetics; it is an exchangeable and consistent random graph process. This work considers the case where $Λ$ is the beta measure. We prove a dynamic law of large numbers for the numbers of blocks containing $1,...…

Composition Tracking for Collisions Between Differentiated Bodies in REBOUND
Previous research suggests that impacts between planetary embryos and planetesimals during the late stages of planet formation can often determine the percentages of core and mantle material that compose the newly formed planets in a system. Previous studies have attempted to include the composition-changing effects of these collisions in N-body simulations of planet formation, often as post-processing codes. In this paper, we present the Differentiated Body Composition Tracker, a new post-proc…

Novel azimuthal observables from two-photon collision at $e^+e^-$ colliders
In this work we advocate a set of novel azimuthal-angle-related observables associated with exclusive hadron production from two-photon fusion at $e^+ e^-$ colliders, taking the $γγ\to ππ$ as a benchmark process. As a direct consequence of the linearly polarized quasi-real photons emitted off the electron and positron beams, the $\cos 2ϕ$ azimuthal asymmetry in dipion production is predicted within the transverse-momentum-dependent (TMD) factorization framework. In numerical analysis, we t…

A test of strangeness quantum number conservation in proton-proton collisions
The study delves into the production of (multi-)strange hadrons in proton-proton collisions at LHC. Novel observables are proposed to distinguish between EPOS4, based on core-corona separation between a thermalised QGP phase and a vacuum phase with global strangeness conservation, and PYTHIA8.3, based on microscopic interactions between Lund strings that conserve strangeness locally. Correlations between a $ϕ$ meson and (multi-)strange hadrons are shown to be an excellent discriminator between…

PCN: A Deep Learning Approach to Jet Tagging Utilizing Novel Graph Construction Methods and Chebyshev Graph Convolutions
Jet tagging is a classification problem in high-energy physics experiments that aims to identify the collimated sprays of subatomic particles, jets, from particle collisions and tag them to their emitter particle. Advances in jet tagging present opportunities for searches of new physics beyond the Standard Model. Current approaches use deep learning to uncover hidden patterns in complex collision data. However, the representation of jets as inputs to a deep learning model have been varied, and …
