Lagrangian analysis of two flavours of Central European heatwaves: Formation under omega blocking versus initiation by subtropical ridges

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate whether Central European heatwaves (HWs) forming under omega blocking differ from those enabled by subtropical ridges, in terms of both air‐mass origin and processes warming air parcels along their way. Using ERA5‐based backward trajectories and a Lagrangian temperature anomaly decomposition, we identify significant differences in the ...

Study on the Movement of Overlying Rock Strata and Surface Movement in Mine Goaf under Different Treatment Methods Based on PS-InSAR Technology

open access: yesApplied Sciences
The goaf treatment of underground metal mines is an important link in mining, and it is particularly important to master the laws of overlying rock strata and surface movement of goaf.

Distance sampling: comparing walked transects and road transects for rock ptarmigan densities and population trends

open access: yesWildlife Biology, EarlyView.
We compared population trends for rock ptarmigan Lagopus muta densities (2003‒2019) derived from walked transects and driven road transects in Mosfellsheiði and Slétta in southwest and northeast Iceland, respectively. The walked transects were laid out according to a random rule.

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Simulation of the Liquid–Solid Coupling in the Distribution Law of Water-Conducted Fractures in Weakly Cemented Overburden Strata as Exemplified by Daliuta Coal Mine in Western China

open access: yesGeofluids
Based on the engineering background of the Daliuta mining area, the distribution of fractures and movement of water within weakly cemented overlying strata were studied with a physical simulation of liquid–solid coupling and a COMSOL numerical simulation

Study on deformation zoning of overlying strata and simulation of rock pressure behavior in longwall top coal caving mining

open access: yesMeitan kexue jishu
At present, longwall top coal caving (LTCC) mining is main mining method for safety and efficiency mines with extremely-thick coal seam in China. However, the deformation movement law of overlying strata on LTCC face directly affects rock pressure ...

THE ANALOG CITY: Maintaining Everyday Life Through Repair and Jugaad

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Urban scholarship consistently discusses improvisation and heterogeneity as central to urban life in the global South. In this article, I bring together scholarship on urban improvisation and the digital world of smart cities to understand the city as analog.

A quasi-Hertzian stress field from an internal source: A possible working model for the Vredefort structure [PDF]

open access: yes
The Vredefort structure is a large domal feature about 110 km southeast of Johannesburg, South Africa, situated within and almost central to the large intracratonic Witwatersrand Basin. This structure consists of an Archean core of ca. 45 km in diameter,
