Chronologie, périodisation, polychronie : les temps de l’histoire de l’art médiéval

open access: yesPerspective, 2008
Establishing the chronology of works of art is one of the first objectives of art history. For the Middle Ages in general, the dearth of written documents means that the work itself is an important source, providing researchers with stylistic ...

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.

A limpet's eye view of post‐glacial isostasy: fixed biological indicators provide new sea‐level index points for the Mid‐Holocene relative highstand in eastern Northern Ireland

open access: yesBoreas
Empirical data for Holocene relative sea level (RSL) changes around the coast of north‐eastern Ireland are sparse. Fixed biological indicators (FBIs), in the form of bioerosional marks made by limpets (Patella) and endolithic traces of other intertidal ...

The WAIS Divide deep ice core WD2014 chronology – Part 2: Annual-layer counting (0–31 ka BP)

open access: yes, 2015
. We present the WD2014 chronology for the upper part (0–2850 m; 31.2 ka BP) of the West Antarctic Ice Sheet (WAIS) Divide (WD) ice core. The chronology is based on counting of annual layers observed in the chemical, dust and electrical conductivity ...

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

open access: yesAdvanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

THE RELATIONSHIP BETWEEN SOLAR AND VOLCANIC ACTIVITY AND THE CHRONOLOGY OF ARCHAEOLOGICAL CULTURES OF EURASIA IN THE 4TH–1ST MILLENNIA BC

open access: yesJournal of Ancient History and Archaeology
A well-known problem of archaeological chronology is that radiocarbon chronology differs from historical chronology. Historical chronology of the Bronze Age corresponds to dendrochronology and radiocarbon chronology in case of using Bayesian statistics ...
