Incipient continent formation by shallow melting of an altered mafic protocrust

open access: yesNature Communications
Understanding how Earth’s continental nuclei first formed in the Archean eon (4.0–2.5 Ga) underpins our notions of early Earth geodynamics. Yet, the nature of Earth’s early protocrust and the primary mechanism for its transformation are poorly understood,

MinDet1: A deep learning-enabled approach for plagioclase textural studies

open access: yesVolcanica
Quantitative textural attributes, such as crystal size distributions or aspect ratios, provide important constraints on the thermal history of rocks.

Lunar reference timescale

open access: yesMetrologia
Abstract Setting up a relativistic lunar reference frame is of a prime importance in the context of future exploration missions to the Moon. If the procedure for building a consistent reference frame within the framework of the general theory of relativity is well established (see resolutions B.3 of International Astronomical Union ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Iranian EFL Learners’ Motivational Fluctuation in Task Performance over Different Timescales [PDF]

open access: yesJournal of English Language Teaching and Learning, 2017
Motivation for learning a new language does not have an all-or-none impact. It is gradually formed and fluctuated over time and on each timescale has varying levels of influence on a person’s endeavor to learn a language.

Shape Cognition and Temporal, Instrumental and Cognitive Constraints on Tonality. Public Peer Review of “Tonality: The Shape of Affect” by Mine Doğantan-Dack.

open access: yesEmpirical Musicology Review, 2013
One of the main aims of Mine Doğantan-Dack's article is to present a theory of the evolutionary emergence of tonality in music and its connections with affective states.

Time Matters: Conceptual and Methodological Considerations in Translation Timescapes

open access: yesChronotopos, 2019
Time is a fundamental concept and context in translation history that merits more specific consideration than it has generally been accorded by translation scholars.

Timescale and Stability in Adaptive Behaviour [PDF]

open access: yes, 2005
Recently, in both the neuroscience and adaptive behaviour communities, there has been growing interest in the interplay of multiple timescales within neural systems. In particular, the phenomenon of neuromodulation has received a great deal of interest within neuroscience and a growing amount of attention within adaptive behaviour research.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
