In Situ Atmospheric Plasma Treatment Enables First‐Layer Adhesion of PEEK on Borosilicate Glass for FDM‐Printed Non‐Assembly Mechanisms

Polymer Engineering &Science, EarlyView.
A printhead‐mounted plasma nozzle activates the PEEK melt and the borosilicate print‐bed at the instant of contact. Only this simultaneous in‐situ activation of both interfaces yields reliable first‐layer adhesion (0.22 MPa). ABSTRACT Fused deposition modeling of poly‐ether‐ether‐ketone (PEEK) requires a high‐temperature build plate, yet PEEK does not ...

Coupled diabatic and frictional forcing of single‐layer vortical flow

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A single‐layer balanced model is used to illustrate how diabatic and frictional forcing of a primary balanced vortical flow can be coupled self‐consistently, including the advection of potential vorticity by the induced transverse circulation. The coupling is illustrated in the context of a developing tropical cyclone, in which boundary‐layer dynamics ...

Anisotropic eddy-viscosity concept for strongly detached unsteady flows [PDF]

, 2007
The accurate prediction of the flow physics around bodies at high Reynolds number is a challenge in aerodynamics nowadays. In the context of turbulent flow modeling, recent advances like large eddy simulation (LES) and hybrid methods [detached eddy ...

Version [1.1] - [2D-xtDCR-LTBEM: A Fortran code for numerical solutions to the unsteady anisotropic-DCR equation of spatio-temporal coefficients]

SoftwareX
Variable coefficient equations are usually used as governing equations for modeling problems which are associated with Functionally Graded Materials (FGM). Version 1.1 - 2D-xtDCR-LTBEM is a Fortran code that can be used to find numerical solutions of two-

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Non‐Alzheimer Aβ deposits in the human CNS: Implications with hypoxia and related conditions

Brain Pathology, EarlyView.
An Aβ deposit in a non‐Alzheimer's brain from an individual who experienced hypoxia/energy failure. Abstract We recently reported the deposition of Aβ in the frontal cortex of individuals who died of acute coronavirus disease 2019 (COVID‐19), or who did not have COVID‐19 but had respiratory distress, or infants with severe cardiac malformations.

Real‐Time Rendering of Dynamic Line Sets using Voxel Ray Tracing

Computer Graphics Forum, EarlyView.
Abstract Real‐time rendering of dynamic line sets is relevant in many visualization tasks, including unsteady flow visualization and interactive white matter reconstruction from Magnetic Resonance Imaging. High‐quality global illumination and transparency are important for conveying the spatial structure of dense line sets, yet remain difficult to ...

Relics, writing, and devotion in early medieval Chelles

Early Medieval Europe, EarlyView.
The discovery in 1983 of a collection of relics with their medieval identificatory tags in the parish church of Chelles opened new avenues for research on devotional and writing practices in this Frankish royal foundation. This is the first systematic study of the corpus of relic labels that accompanied these sacred objects, particularly of the subset ...

The technological impact of diffusion in nanopores [PDF]

, 2005
The impact of nanopore diffusion on the performance of adsorption separation processes is reviewed. Zeolite membrane processes and kinetically selective cyclic adsorption processes depend for their selectivity on differences in intracrystalline diffusion
