The features of the Paleozoic-Mesozoic complexes of Kiber Cape (Chukotka, Arctic Russia): a structural-deforma-tion analysis

Известия высших учебных заведений: Геология и разведка, 2017
Three major regional deformation stages of Central Chukotka tectonic evolution were determined in Paleozoic-Mesozoic deposits of Kiber Cape. The research was based on a structural analysis of the linear and planar elements.

Fatigue Crack Initiation and Growth in Nanocrystalline Ni at Multiple Length‐Scales

Advanced Engineering Materials, EarlyView.
Overview of miniaturized in situ SEM fatigue setup and resultant fatigue crack growth data for nanocrystalline Ni. The presented study focuses on the analysis of fatigue crack growth rate (FCGR) in focused ion beam‐notched microcantilevers prepared from nanocrystalline (NC) Ni as a model material.

Collision-stimulated abortive termination model predicts reduced protein output at high initiation rates. [PDF]

, 2019
(A) Schematic of different abortive termination models simulated in (B). ka denotes the nonzero rate of abortive termination of ribosomes from indicated configurations. In the TJ model, ribosomes do not abort translation. In the SAT model, only ribosomes

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

Advanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation

Visual cueing for collision avoidance system [PDF]

, 2012
The modern Traffic Alert and Collision Avoidance System (TCAS) used in airlines today is the TCAS II. It provides pilots with both Traffic Advisory (TA) and Resolution Advisory (RA) which in turn reduces the incidence of mid-air collisions.

Optimising the care of the trapped patient following a motor vehicle collision: A UK-Based Delphi consensus study

Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine
Background Motor vehicle collisions (MVCs) are a leading cause of injury and death worldwide. Up to 40% of casualties may become trapped and entrapment is associated with delayed care and worse outcomes.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Efficient and Reliable Self‐Collision Culling Using Unprojected Normal Cones [PDF]

, 2017
We present an efficient and accurate algorithm for self‐collision detection in deformable models. Our approach can perform discrete and continuous collision queries on triangulated meshes.
