Investigating relationships among strontium, barium, and seasonality in wild baboons
Archaeometry, EarlyView.Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

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.

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.

INTERSTELLAR METEOROIDS WITH ALMOST HYPERBOLIC ORBITS
Odessa Astronomical Publications, 2017 Opportunities for detecting interstellar meteoroids with implicit hyperbolic orbits are explored. It is indicated that the idea of their interstellar origin is based on the distribution of hyperbolic orbits of meteoric particles according to elongation ...

Chelyabinsk Meteoroid Acoustic Effects [PDF]
Radio physics and radio astronomy, 2017 Purpose: The parameters (period, time delay, celerity, duration, and the rate of attenuation) of the acoustic signal which was generated during the Chelyabinsk meteoroid passage and explosion on February 15, 2013 are investigated along with atmospheric parameters.

Mass distribution of lyrid meteoroids [PDF]
, 2010 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.

, 2004 International audienceDetermining the velocity of meteoroids as they enter the Earth's atmosphere is very important since the value is fundamental in calculating the orbit of the meteoroid and hence eventually its origin.

Modeling the Meteoroid Environment Far from the Ecliptic Plane
The Planetary Science JournalWe describe a new version (numbered 3.1) of NASA’s Meteoroid Engineering Model, in which we extend the model to handle locations that lie more than a few degrees in latitude off the ecliptic plane.
