Tracing Identity in a Fragmented Past: Multi‐Proxy Analysis of Human Skeletal Remains From Dungowan Creek, New South Wales, Australia

open access: yesArchaeometry, EarlyView.
ABSTRACT Human skeletal remains constitute critical archaeological evidence for reconstructing past societies, yet their investigation requires careful ethical, cultural, and legislative consideration. This paper reports on the discovery, recovery and analysis of a set of skeletal remains encountered during a cultural heritage management (CHM ...

Modeling Tidal Datums and Spatially Varying Uncertainty in the Texas and Western Louisiana Coastal Waters

open access: yesJournal of Marine Science and Engineering, 2019
Tidal datums are key components in NOAA’s Vertical Datum transformation project (VDatum), which enables effective vertical transformation of the water level between tidal, orthometric, and ellipsoid -based three-dimensional reference systems.

Spiders in the mosaic: How habitat heterogeneity and structure drive local spider diversity in a Mediterranean forest

open access: yesEcological Entomology, EarlyView.
We assessed alpha‐ and beta‐diversity patterns of spiders across different forests and across vegetation layers (ground, shrub, low canopy) at local spatial scales across various Mediterranean forest types. Across forests, alpha‐diversity increased with habitat heterogeneity, which also drove beta‐diversity patterns across plots .

Layered Radial Aquifer Model for Open‐Pit Mine Closure with Managed Aquifer Recharge

open access: yesGroundwater, EarlyView.
A radially symmetric layered aquifer model (unconfined–aquitard–confined) coupled to a pit‐lake water balance is developed to screen managed aquifer recharge (MAR) after open‐pit mine closure. Dimensionless type curves quantify trade‐offs between pit recovery time, pumping/recycling, and unconfined mounding as functions of aquifer time scales, aquitard

Converting NAD83 GPS heights into NAVD88 elevations with LVGEOID, a hybrid geoid height model for the Long Valley volcanic region, California [PDF]

open access: yes, 2008
A GPS survey of leveling benchmarks done in Long Valley Caldera in 1999 showed that the application of the National Geodetic Survey (NGS) geoid model GEOID99 to tie GPS heights to historical leveling measurements would significantly underestimate the

Demonstration of an instream flow model to accommodate a threatened tiger beetle in riverine dune habitat

open access: yesInsect Conservation and Diversity, EarlyView.
Burrows of the threatened Gibson's Big Sand Tiger Beetle in riverine dune habitats are susceptible to flooding through managed flows. HEC‐RAS modelling identified the flow thresholds above which flooding would occur for burrows and affect the beetle larvae. These findings provide instream flow guidelines for conserving this threatened species and guide

Tropical Fukaya Algebras

open access: yes, 2020
We introduce a tropical version of the Fukaya algebra of a Lagrangian submanifold and use it to show that tropical Lagrangian tori are weakly unobstructed.

Crystalline evolutions with rapidly oscillating forcing terms [PDF]

open access: yes, 2017
We consider the evolution by crystalline curvature of a planar set in a stratified medium, modeled by a periodic forcing term. We characterize the limit evolution law as the period of the oscillations tends to zero.

Ridge Preservation Compared With Spontaneous Healing in Extraction Sockets With Buccal Dehiscence: A Randomized Clinical Trial

open access: yesJournal of Periodontal Research, EarlyView.
Alveolar ridge preservation using a bone allograft and collagen membrane significantly limited hard and soft tissue dimensional changes and promoted buccal bone gain compared with spontaneous healing in sockets with buccal dehiscence defects. This approach reduced the need for additional bone grafting, despite higher short‐term postoperative morbidity.
