Torture and scepticism in Papua New Guinea witch hunts Torture et scepticisme dans les chasses aux sorcières en Papouasie‐Nouvelle‐Guinée

Journal of the Royal Anthropological Institute, EarlyView.
For over a century, anthropologists have documented the many institutions that exist to respond to witchcraft and the uncanny that it names: oracles that attempt to produce certainty by naming the witch; moots in which grievances are aired; trials in magistrates’ courts that attempt to satisfy the community while preserving the life of the accused ...

Dislocation Reduction by Glide in Epitaxial IV-VI Layers on Si Substrates [PDF]

, 2018
It is explained with a simple model why the reduction of threading dislocation (TD) densities in epitaxial lattice and thermal expansion mismatched IV-VI layers such as PbSe(111) on Si(111) substrates follows a 1/h 2 dependence where h is the thickness ...

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds

Journal of Anatomy, EarlyView.
The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Microscopic phase field and Peierls-Nabarro modeling of dislocation dissociation, glide, and twinning in FCC systems [PDF]

, 2014
In this study, a 3D microscopic dynamic phase field (PF) approach is developed to model dislocation processes in FCC single crystals. Being based on two order parameters per glide plane, this approach is formally similar to existing static Peierls ...

Dislocation Reactions in a Crystal of Soft Particles in the Form of a Transversely Compressed Bundle of Carbon Nanotubes

C
Properties of defects in crystals composed of soft particles, such as colloids, differ markedly from those in metals. In this work, dislocation reactions in a bundle of carbon nanotubes (CNTs) are investigated using relaxational molecular dynamics.

Periodontitis and Diabetes: Mechanistic Evidence of a Circular Relationship

Journal of Periodontal Research, EarlyView.
This narrative review aimed to explore the underlying mechanisms that connect periodontitis to diabetes (and vice versa) and that influence disease susceptibility, progression and response to treatment. ABSTRACT The circular relationship between periodontitis and diabetes mellitus is one of the most established oral‐systemic links.

Divergent evolution of slip banding in CrCoNi alloys

Nature Communications
Metallic materials under high stress often exhibit deformation localization, manifesting as slip banding. Over seven decades ago, Frank and Read introduced the well-known model of dislocation multiplication at a source, explaining slip band formation ...
