Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part I Reproducibility of diet inference using different instruments

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.

SARchaeological Prospection: Synthetic Aperture Radar for the Reconstruction and Mapping of Temperate Floodplain Environments

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Temperate river floodplains present a significant challenge for archaeologists, as cultural and palaeoenvironmental remains are often difficult to locate but can be exceptionally well preserved, especially where groundwater levels are high. In these alluvial environments, the deposition of thick, fine‐grained sediments has potential to deeply ...

Speckle Observations With PISCO in Calern (France): II. Astrometric Measurements of Visual Double Stars in 2017–2018 and New or Revised Orbits for A1913 AB, A1710, COU1394, BU1185, A122, A570, HU577, COU812, HU332, A2095 AB, and A884

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We present relative astrometric measurements of visual double stars, made in 2017–2018 with the speckle camera PISCO at the 1‐m Epsilon telescope of the C2PU facility (Observatoire de la Côte d'Azur, Calern site). Our observing list contains orbital couples as well as double stars whose motion is still uncertain.

Uncertainties in Ground‐Based Visual Double Star Measures—II Accuracy of Measures

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Letchford and White 2025, Paper I, determined the uncertainties in ground‐based historic measures of double stars. In this paper, the accuracy of 26,205 ground‐based measures of 857 visual double stars, made since ∼$$ \sim $$1780, is determined relative to space‐based measures based on positions and proper motion from the HIPPARCOS (via ASCC ...

Continuous purification of a parvovirus using two aqueous two‐phase extraction steps

open access: yesBiotechnology Progress, EarlyView.
Abstract Aqueous two‐phase systems (ATPS) are a liquid–liquid extraction method that offers low‐cost, continuous‐adaptable virus purification. A two‐step ATPS using polyethylene glycol (PEG) and sodium citrate that recovered 66% of infectious porcine parvovirus with 2.0 logs of protein removal and 1.0 logs of DNA removal in batch has now been run ...

A Browser‐Based Tool for Assessing Accuracy of Isothermal Titration Calorimetry‐Derived Parameters: Kd, ΔH°, and n

open access: yesChemBioChem, EarlyView.
Accurate Kd determination is crucial for drug discovery and diagnostics. Accuracy confidence intervals (ACI)‐ITC, a browser‐based tool, calculates ACI for isothermal titration calorimetry (ITC)‐derived parameters, considering systematic errors in concentration and heat measurements.
