Approximate Injectivity [PDF]

open access: yesApplied Categorical Structures, 2017
In a locally $λ$-presentable category, with $λ$ a regular cardinal, classes of objects that are injective with respect to a family of morphisms whose domains and codomains are $λ$-presentable, are known to be characterized by their closure under products, $λ$-directed colimits and $λ$-pure subobjects.

An easy and safe method of subconjunctival injection of antimetabolites in glaucoma surgery

open access: yesExploration of Medicine, 2023
Aim: The use of 5-fluorouracil in glaucoma surgery is associated with a high risk of corneal complications, as even minimal doses of the drug at the ocular surface inhibit corneal epithelial cell division and lead to corneal epitheliopathy and erosion ...

ON INJECTIVITY AND P-INJECTIVITY, IV [PDF]

open access: yesBulletin of the Korean Mathematical Society, 2003
[For part I cf. J. Math. Kyoto Univ. 27, 439-452 (1987; Zbl 0655.16012).] A left \(A\)-module \(M\) is called \(p\)-injective if for every principal left ideal \(P\) of \(A\), every \(A\)-homomorphism from \(P\) to \(M\) can be extended to \(A\) to \(M\).

Aspiration in injections: should we continue or abandon the practice? [version 3; referees: 2 approved]

open access: yesF1000Research, 2017
Aspiration during any kind of injection is meant to ensure that the needle tip is at the desired location during this blind procedure. While aspiration appears to be a simple procedure, it has generated a lot of controversy concerning the perceived ...

MOVPE-Grown Quantum Cascade Laser Structures Studied by Kelvin Probe Force Microscopy

open access: yesCrystals, 2020
A technique for direct study of the distribution of the applied voltage within a quantum cascade laser (QCL) has been developed. The detailed profile of the potential in the laser claddings and laser core region has been obtained by gradient scanning ...

Long wavelength VCSEL-by-VCSEL optical injection-Locking [PDF]

open access: yes, 2009
VCSEL-by-VCSEL optical injection-locking to obtain high cut-off frequencies of 1.3 μm Vertical-Cavity Surface-Emitting Lasers (VCSELs) is demonstrated. A detailed physical explanation of the underlying mechanism is presented.

A Fault Injection Environment for Microprocessor-based Board [PDF]

open access: yes, 1998
Evaluating the faulty behaviour of low-cost microprocessor-based boards is an increasingly important issue, due to their usage in many safety critical systems. To address this issue, the paper describes a software-implemented fault injection system based

Study on Premixed Combustion in a Diesel Engine with Ultra-multihole Nozzle

open access: yesJournal of Combustion, 2011
This study proposed a new low-temperature premixed combustion mode to achieve the simultaneous reduction of NOx and soot emissions in a volume production diesel engine of CA6DF by reconstructing key systems. Some developments of this diesel engine are as
