An End Degree for Digraphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT In this paper we define a degree for ends of infinite digraphs. The well‐definedness of our definition in particular resolves a problem by Zuther. Furthermore, we extend our notion of end degree to also respect, among others, the vertices dominating the end, which we denote as combined end degree.

Sonographic localisation of lymph nodes suspicious of metastatic breast cancer to surgical axillary levels

open access: yesJournal of Medical Radiation Sciences, Volume 72, Issue 1, Page 119-138, March 2025.
Sonographic imaging is used to identify the presence, number and location of malignant lymph nodes. Axillary lymph nodes suspicious of harbouring breast cancer metastasis can be localised to three surgical axillary levels. This paper will unpack the axillary anatomy, muscular sonographic landmarks, surgical axillary lymph node levels and the ...

The end of the INF-Treaty: Context and consequences. Egmont European Security Brief No. 111 July 2019 [PDF]

open access: yes, 2019
On 2 August both the US and the Russian Federation will no longer be restrained by the Intermediate-Range Nuclear Forces (INF) Treaty (1987). Early this century it gradually became clear that Russia wanted to step out of the Treaty, by which it felt ...

Surveying immune and inflammatory alterations in periodontitis among individuals with Down syndrome: A preliminary cross‐sectional study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Individuals with Down syndrome (DS) are particularly vulnerable to early‐onset and rapidly progressing periodontitis, yet the local immune‐inflammatory alterations that contribute to this susceptibility are not fully understood. This study aimed to characterize cytokine profiles in gingival crevicular fluid (GCF) from individuals ...

A Nonlinear Quantitative Model for Measuring Concentration Ratios From Raman Intensities

open access: yesJournal of Raman Spectroscopy, EarlyView.
Estimating concentration from Raman intensity ratios is complicated by cross‐contributions from overlapping peaks, causing measured ratios to deviate from the linear behavior assumed in conventional quantitative models. This nonlinear method fully accounts for cross‐contributions, allowing estimation of concentration over several orders of magnitude ...
