Method Dependence in Thermal Conductivity and Aerodynamic Roughness Length Estimates on a Debris‐Covered Glacier

open access: yesJournal of Geophysical Research: Earth Surface, Volume 130, Issue 6, June 2025.
Abstract Rock debris partially covers glaciers worldwide, with varying extents and distributions, and controls sub‐debris melt rates by modifying energy transfer from the atmosphere to the ice. Two key physical properties controlling this energy exchange are thermal conductivity (k) $(k)$ and aerodynamic roughness length z0 $\left({z}_{0}\right ...

Prerequisites for a computational approach to Minoan chronology

open access: yesArchaeometry, Volume 67, Issue S1, Page 110-130, June 2025.
Abstract The paper examines the development, adoption, and limitations of the relative chronology system for Minoan pottery, initially established by Sir Arthur Evans and Duncan Mackenzie during the excavation of Knossos (1900–1906). Despite its weaknesses, this system remained largely unchanged due to its convenience rather than its accuracy.

Survival rates of planets in open clusters: the Pleiades, Hyades, and Praesepe clusters [PDF]

open access: yesAstronomy & Astrophysics, 2018
Context. In clustered environments, stellar encounters can liberate planets from their host stars via close encounters. Although the detection probability of planets suggests that the planet population in open clusters resembles that in the field, only a

Proustian Grief

open access: yesEuropean Journal of Philosophy, Volume 33, Issue 2, Page 721-736, June 2025.
Abstract Proust wrote vividly about grief, but he has not been recognised or studied as a philosopher of grief. It is time that he was. For a powerful and compelling philosophy of grief emerges from the pages of his magnum opus. Though philosophical work on Proust has not turned to this theory of grief, philosophers writing about grief have often drawn

Brown dwarfs in wide-field surveys

open access: yesEPJ Web of Conferences, 2011
In this invited talk, I briefly summarise early photometric and proper motion surveys carried out in the nearest and youngest open clusters to introduce the motivation behind the Galactic Cluster component of the UKIRT Infrared Deep Sky Survey ...

The advantages of using drones over space-borne imagery in the mapping of mangrove forests. [PDF]

open access: yesPLoS ONE, 2018
Satellite data and aerial photos have proved to be useful in efficient conservation and management of mangrove ecosystems. However, there have been only very few attempts to demonstrate the ability of drone images, and none so far to observe vegetation ...

Stellar twins determine the distance of the Pleiades [PDF]

open access: yesAstronomy & Astrophysics, 2016
Since the release of the Hipparcos catalog in 1997, the distance to the Pleiades open cluster has been heavily debated. The distance obtained from Hipparcos and those by alternative methods differ by 10 to 15 %. As accurate stellar distances are key to understanding stellar structure and evolution, this dilemma puts the validity of stellar evolution ...

Geometric and Spatial Analysis of Wing‐Like Intrusions as Outcrop Analogues for Subsurface Analysis

open access: yesBasin Research, Volume 37, Issue 3, May/June 2025.
Wing‐like intrusions are key features in sand injectite complexes, with geometries visible on seismic data. This study integrates field and digital mapping of two San Joaquin Basin outcrops and applies them as subsurface analogues. Results reveal complex geometries that enhance reservoir characterization and highlight the role of sub‐seismic intrusive ...

Artificial Mangrove Species Mapping Using Pléiades-1: An Evaluation of Pixel-Based and Object-Based Classifications with Selected Machine Learning Algorithms

open access: yesRemote Sensing, 2018
In the dwindling natural mangrove today, mangrove reforestation projects are conducted worldwide to prevent further losses. Due to monoculture and the low survival rate of artificial mangroves, it is necessary to pay attention to mapping and monitoring ...

Significant Seismic Risk Potential From Buried Faults Beneath Almaty City, Kazakhstan, Revealed From High‐Resolution Satellite DEMs

open access: yesEarth and Space Science, 2021
Major faults of the Tien Shan, Central Asia, have long repeat times, but fail in large (Mw 7+) earthquakes. In addition, there may be smaller, buried faults off the major faults which are not properly characterized or even recognized as active. These all
