Making vertebrate fossil radiocarbon dates more useful for global scientific research

open access: yesJournal of Quaternary Science, Volume 40, Issue 8, Page 1309-1335, November 2025.
ABSTRACT Radiocarbon dating of bones is essential for reconstructing timelines of species' occurrences, domestication, extinction, migrations, and interactions with Quaternary environments. Many studies compile these chronologies at continental to global scales by aggregating radiocarbon dates from various sources, often balancing data quantity and ...

An Evidential Framework for Localization of Sensors in Indoor Environments

open access: yesSensors, 2020
Indoor localization has several applications ranging from people tracking and indoor navigation, to autonomous robot navigation and asset tracking. We tackle the problem as a zoning localization where the objective is to determine the zone where the ...

On the nature of sn stars. I. A detailed abundance study [PDF]

open access: yes, 2014
The sn stars present sharp Balmer lines, sharp metallic lines and broad coreless He I lines. Initially Abt & Levato proposed a shell-like nature to explain the sn stars, although this scenario was subsequently questioned.

Market Potential, Road Accessibility, and Firm Births: Evidence From 20 Years of Road Investment

open access: yesJournal of Regional Science, Volume 65, Issue 4, Page 984-1016, September 2025.
ABSTRACT This paper investigates the causal effects of road accessibility, measured by market potential, on firm births in Portuguese municipalities between 1991 and 2016, a period marked by significant road improvements. We address the endogeneity of market potential by employing instrumental variables within Poisson Pseudo‐maximum Likelihood ...

Is strong CP invariance due to a massless up quark?

open access: yes, 2002
A standing mystery in the Standard Model is the unnatural smallness of the strong CP violating phase. A massless up quark has long been proposed as one potential solution.

Chemical constitutions in the Colour Index™: A century of colourant classification

open access: yesColoration Technology, Volume 141, Issue 4, Page 427-472, August 2025.
Abstract This article details how the Colour Index™ (CI) system categorises and unambiguously labels commercial dyes and pigments based upon their chemical constitutions. It outlines the current process by which colourants that are new to the market find a place within CI and acquire generic identifiers.
