Shield tilings

open access: yesCoRR, 2023
We provide a complete description of the edge-to-edge tilings with a regular triangle and a shield-shaped hexagon with no right angle. The case of a hexagon with a right angle is also briefly discussed.

Uncertainty quantification and sensitivity analysis of a nuclear thermal propulsion reactor startup sequence

open access: yesFrontiers in Nuclear Engineering
The research presented in this article describes progress in applying stochastic methods, uncertainty quantification, parametric studies, and variance-based sensitivity analysis (also known as Sobol sensitivity analysis) to a full-core model of a nuclear

A computational fluid dynamic analysis of the effect of weld nozzle geometry changes on shielding gas coverage during gas metal arc welding [PDF]

open access: yes, 2013
Three geometry changes to the inner bore of a welding nozzle and their effects on weld quality during gas metal arc welding (GMAW) were investigated through the use of computational fluid dynamic (CFD) models and experimental trials. It was shown that an

Durability assessment of mechanochemically activated geopolymer concrete with a low molarity alkali solution

open access: yesCase Studies in Construction Materials
The prevailing practices of geopolymer concrete (GC) preparation use a high concentration of alkali activators, which is uneconomical. It is imperative to develop GC of low-concentration activators with enhanced durability for field implementation ...

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

THE PILE SHIELD. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1902
It has often happened, even in the best hands, that the patient has been severely burned, when the ordinary clamp and cautery method has been employed in the operation for piles, causing the surgeon no end of annoyance. To avoid this, I have devised a little instrument that eliminates such accidents; this instrument is small, inexpensive, portable ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Numerical and experimental analysis of thermal behaviour of high voltage power cable in unfilled ducts

open access: yesScientific Reports
The work addresses the topic of the thermal study of high-voltage power cables installed inside plastic pipes in the absence of filling. The presence of air inside the pipe creates an insulating layer that does not favor heat exchange and makes the ...
