Alternation of must, have to, and need to in English as a lingua franca

open access: yesWorld Englishes, EarlyView.
Abstract This study explores the grammatical variability of modal auxiliary verbs in English as a lingua franca. Focusing on the ongoing change must, have to, and need to, this research utilizes two spoken corpora: the Vienna–Oxford International Corpus of English (VOICE) and the Asian Corpus of English (ACE).

Origin and Dynamical Evolution of Comets and their Reservoirs

open access: yes, 2005
This text was originally written to accompany a series of lectures that I gave at the `35th Saas-Fee advanced course' in Switzerland and at the Institute for Astronomy of the University of Hawaii. It reviews my current understanding of the dynamics of comets and of the origin and primordial sculpting of their reservoirs.

Separation of Polyamide 66 From Blends With Wool Through Selective Dissolution: Implications of the Presence of Dyes

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 33, September 5, 2026.
The study assesses dye impacts on PA66/wool recycling via selective PA66 dissolution in calcium chloride–ethanol–water and water reprecipitation. Acid dyes migrate into solvent, yielding color‐free, melt‐spinnable PA66 and reusable wool. Metal‐complex dyes remain, altering PA66 melt viscosity and requiring extraction or repurposing.

Synchrotron‐Based X‐Ray Tomography of Strontium Phosphate Chemical Gardens

open access: yesChemSystemsChem, Volume 8, Issue 5, September 2026.
Synchrotron‐based X‐ray tomography at the DanMAX beamline (MAX IV laboratory) is able to address challenges related to in situ observations at high spatial (sub‐micron) resolution in the field of chemical gardens or non‐equilibrium systems in general. The results therefore reflect a buoyancy‐linked mechanism of growth as well as the mineralization of ...

Renewing Concerns of Technical Complexity in Accidents Research: An Argument to Retain Perrow's “First Thesis”

open access: yesJournal of Contingencies and Crisis Management, Volume 34, Issue 3, September 2026.
ABSTRACT It has been 40 years since Charles Perrow published the landmark work Normal Accidents ([1984]1999), built largely on an analysis of the Three Mile Island (TMI) nuclear power plant accident. While still a highly influential framework in the study of complex systems, the status of the argument remains in flux.
