Faults as Volumetric Weak Zones in Reservoir-Scale Hydro-Mechanical Finite Element Models—A Comparison Based on Grid Geometry, Mesh Resolution and Fault Dip

Energies, 2020
An appropriate representation of faults is fundamental for hydro-mechanical reservoir models to obtain robust quantitative insights into the spatial distribution of stress, strain and pore pressure.

Refining point-cloud neighborhood construction for improved classificationGithubZenodoZenodo

Science of Remote Sensing
3D point clouds enable us to capture the structure of our environment in high detail. In the context of urban areas, point clouds allow us to segment single objects, detect changes, and generate detailed maps of highly complex scenes.

Zwischen Flexibilisierung und Stillstand. Raumzeitliche Arrangements und soziale Ungleichheiten in der Auslagerung von Hausarbeit über städtische Lieferdienste [PDF]

Geographica Helvetica
In the course of the Covid-19 pandemic, class diagnostic narratives surrounding an emerging servant economy gained traction also in Europe. Especially grocery and food-delivery services in larger cities became emblematic for an urban middle class ...

Ba[C(CN)3]2 and Pb[C(CN)3]2: Two Remarkably Different Heavy Main‐Group Metal Bistricyanomethanides

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 8, 25 May 2026.
Metathesis reactions of either barium dichloride, BaCl2, or lead dichloride, PbCl2, respectively, with Ag[C(CN)3] in water yielded single crystals of anhydrous Ba[C(CN)3]2 and Pb[C(CN)3]2. Ba[C(CN)3]2 crystallizes in the monoclinic space group P21/n (no. 14) with the lattice parameters a = 437.98(3) pm, b = 1685.36(11) pm, c = 1398.87(9) pm, β = 96.541(

A workflow for building and calibrating 3-D geomechanical models &ndash a case study for a gas reservoir in the North German Basin [PDF]

Solid Earth, 2013
The optimal use of conventional and unconventional hydrocarbon reservoirs depends, amongst other things, on the local tectonic stress field. For example, wellbore stability, orientation of hydraulically induced fractures and – especially in fractured ...

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, Volume 309, Issue 4, Page 864-911, April 2026.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.
