Provisioning a Silk Road City: Herd Management Strategies at the Urban Site of Dzhankent, Kazakhstan

Archaeometry, EarlyView.
ABSTRACT This study presents evidence for herd management at the early medieval city of Dzhankent in southern Kazakhstan. Located along the Northern Silk Road, Dzhankent was a key trading node linking northern and southern areas between the 9th and 10th centuries ce.

Exogenous carbonaceous material on Phobos

Astronomy & Astrophysics
Aims. We analyze Mars Express (MeX)/OMEGA Phobos’ data in the 2.5–3.9 μm range to investigate the presence of organic material. Methods. We applied a thermal correction to the OMEGA data and identified regions of interest (ROIs) to extract mean spectra ...

Ecological variability of Hippopotamus antiquus from the late Early–Middle Pleistocene of Megalopolis Basin (Greece): Evidence for dynamic habitats in a glacial microrefugium

Boreas, EarlyView.
This study investigates the ecology of the extinct European Hippopotamus from the late Early–Middle Pleistocene (c. 900–400 ka) sequence of the Megalopolis Basin, a glacial microrefugium for temperate taxa in southern Greece. Using stable carbon (δ13C) and oxygen (δ18O) isotope analyses and microwear analyses of Hippopotamus dental elements, we ...

Метеороїд [Meteoroid]

, 2018
МЕТЕОРО́ЇД За визначенням Міжнар. астроном. союзу, М. – твердий об'єкт, що рухається в міжпланет. просторі, розміром значно менший за астероїд, але суттєво більший за атом. Лондон. королів. астроном. товариство запропонувало ін. формулювання, згідно з яким М. – тіло діаметром від... ⚠️ Цей запис містить лише бібліографічні метадані.

Solar System material reaching neighboring star systems

Astronomy & Astrophysics
Context. In our Solar System, few macroscopic objects have been observed to be moving in hyperbolic orbits and, thus, they must have originated from interstellar space. Some meteoroids are also suspected to have an interstellar origin.

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

Computer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

Mass distribution of lyrid meteoroids

, 2020
Long-term visual observations of the Lyrid meteoroid shower have been analyzed to determine the mass distribution of Lyrid meteoroids. The value of the parameter S has been confirmed to be less than 1.8, which is normally assumed for meteoroid streams ...

Affinification: A Fine Approximation of Deformations

Computer Graphics Forum, EarlyView.
Abstract We introduce affinification, a novel method for accelerating physics‐based animation of elastic solids. During a time‐dependent simulation, our method automatically partitions the space into affine and elastic regions depending on the deformation.
