Insights into the genesis of thick halite in the Kuqa Depression (Tarim Basin, China): New mineralogical, lithological and geochemical evidence

open access: yesThe Depositional Record, EarlyView.
Halite thickness in Mbr 2 of the Kumugeliemu can reach 1000 m. The thick halite is associated with sedimentary rock with shallow water fabrics. The thick halite was formed in a shallow‐sea water environment. The ‘Multiple transgression‐salt‐forming’ model was established.

Whitney stratifications and the continuity of local Lipschitz Killing curvatures [PDF]

open access: yesarXiv, 2015
We prove that local Lipschitz Killing curvatures of definable sets in a polynomially bounded o-minimal structure are continuous along strata of Whitney stratifications and locally Lipschitz if the stratifications are (w)- regular.

Late Pleistocene to Holocene sedimentation in the Great Blue Hole (Lighthouse Reef, Belize): Results from a 30 m long core

open access: yesThe Depositional Record, EarlyView.
A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes

Effects of Isothermal Stratification Strength on Vorticity Dynamics for Single-Mode Compressible Rayleigh-Taylor Instability [PDF]

open access: yesarXiv, 2018
The effects of isothermal stratification strength on vorticity dynamics for single-mode Rayleigh-Taylor instability (RTI) are examined using two dimensional fully compressible wavelet-based direct numerical simulations. The simulations model low Atwood number ($A=0.04$) RTI development for four different stratification strengths, corresponding to Mach ...

Stronger effect of temperature on body growth in cool than in warm populations suggests lack of local adaptation

open access: yesEcography, EarlyView.
Body size is a key functional trait that has declined in many biological communities, partly due to changes in individual growth rates in response to climate warming. However, our understanding of growth responses in natural populations is limited by relatively short time series without large temperature contrasts and unknown levels of adaptation to ...

Three instability stratifications of the stack of Higgs bundles on a smooth projective curve [PDF]

open access: yesarXiv, 2019
We study three instability stratifications of the stack of twisted Higgs bundle of a fixed rank and degree on a smooth complex projective curve. The first is the Harder-Narasimhan (HN) stratification, defined by the instability type of the Higgs bundle.

Global phylogenetic and functional structure of rodent assemblages

open access: yesEcography, EarlyView.
Exploring the global patterns of phylogenetic and functional structure of assemblages is key to describe the distribution of biodiversity on Earth and to predict how communities and ecosystem functioning may be affected by anthropogenic pressures. Rodent communities have been studied in this regard in the past, but previous work largely focused on ...

On the stratification by orbit types II [PDF]

open access: yesarXiv, 2017
When we have a proper action of a Lie group on a manifold, it is well known that we get a stratification by orbit types and it is known that this stratification satisfies the Whitney (b) condition. In a previous article we have seen that the stratification satisfies the strong Verdier condition.

Assessing benthos through predator stomach contents: spatiotemporal modeling of abundance and habitat use

open access: yesEcography, EarlyView.
In shelf ecosystems, benthic invertebrates facilitate nutrient recycling and the transfer of energy to higher trophic levels. However, large‐scale monitoring through direct sampling (e.g. using benthic grabs or bottom trawls) can be costly in terms of time and labor.
