Effect of confining pressure on fracture characteristics and mineralogical behavior of tight sandstone specimens after hydraulic fracturing

Deep Underground Science and Engineering, EarlyView.
Hydraulic fracturing in tight sandstone and fracture propagation characteristics using backscattered electron‐scanning electron microscope (BSE‐SEM) images. Abstract This study focuses on hydraulic fracturing experiments conducted under triaxial conditions on tight sandstone specimens from Shivpuri district, Madhya Pradesh, India.

Chromatin Conformation Links Putative Enhancers in Intracranial Aneurysm–Associated Regions to Potential Candidate Genes

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background We previously showed that intracranial aneurysm (IA)–associated single‐nucleotide polymorphisms are enriched in promoters and putative enhancers identified in the human circle of Willis, on which IAs develop, suggesting a role for promoters ...

First detection of phase-dependent colliding wind X-ray emission outside the Milky Way [PDF]

, 2007
After having reported the detection of X-rays emitted by the peculiar system HD5980, we assess here the origin of this high-energy emission from additional X-ray observations obtained with XMM-Newton.

Anthropologist, heal thyself: Toward an anthropology of healing through relational interbeing

Feminist Anthropology, EarlyView.
Abstract I call for an anthropology that confronts its own woundedness. Anthropologists often bear witness to suffering but rarely examine how our own grief, trauma, and institutional distress shape the affective tone of our work. Drawing on fieldwork with Runa (Quechua) women affected by forced sterilization in Peru and guided by my collaborator and ...

Topology‐aware anatomical segmentation of the Circle of Willis: HUNet unveils the vascular network

IET Image Processing
This research investigates the Circle of Willis, a critical vascular structure vital for cerebral blood supply. A modified novel dual‐pathway multi‐scale hierarchical upsampling network (HUNet) is presented, tailored explicitly for accurate segmentation ...

The Incidence of Berry Aneurysm in the Iranian Population: An Autopsy Study [PDF]

Intracranial berry aneurysms are the most common kind of aneurysms in the brain, and are caused by head trauma in 1% of cases. They may remain asymptomatic for a long time or may rupture and cause intracranial hemorrhage.

Immersed boundary method predictions of shear stresses for different flow topologies occuring in cerebral aneurysms [PDF]

, 2010
A volume-penalizing immersed boundary method is presented that facilitates the computation of incompressible fluid flow in complex flow domains. We apply this method to simulate the flow in cerebral aneurysms, and focus on the accuracy with which the ...

Membership‐Making in Diverse Societies: Revisiting the Idea of Society as a Common Possession

Journal of Applied Philosophy, EarlyView.
ABSTRACT The traditional aim of Western social democracy has been to create a society that is a ‘common possession’ of its members (in T.H. Marshall's words). Social democratic politics has therefore been both society‐making and membership‐making, orienting people to a shared society as an object of attachment and loyalty, and nurturing membership ...
