A proof of Menger's Theorem by contraction

open access: yesDiscussiones Mathematicae Graph Theory, 2002
The author gives a very short proof of the classical Menger theorem concerning the number of disjoint \(AB\)-paths of a finite graph for two subsets \(A\) and \(B\) of its vertex set.

Radikale Kaskadenreaktion, welche die Kreuzkupplung von Olefinen mit der Smiles‐Truce‐Umlagerung kombiniert

open access: yesAngewandte Chemie, Volume 138, Issue 23, 1 June 2026.
Wir stellen eine kobaltkatalysierte Radikalkaskade vor, die zwei Alken Ausgangsstoffe effizient miteinander verbindet und so in einem einzigen Schritt mehrere Bindungen aufbaut. Der Prozess beginnt mit einem kobaltkatalysierten Wasserstoffatomtransfer an eine Styrol‐Doppelbindung, gefolgt von einer Giese‐Addition.

Tolerability and Feasibility of Minimally Invasive Canine Skin Sampling: Excellent Tolerability Meets Transcriptomic Challenges

open access: yesVeterinary Dermatology, Volume 37, Issue 3, Page 375-385, June 2026.
ABSTRACT Background Advances in transcriptomics have driven the demand for minimally invasive, reproducible and high‐yield skin sampling methods, particularly for studying inflammatory skin diseases in companion animals. Hypothesis/Objectives We tested tolerability, feasibility and RNA quantity and quality of three minimally invasive skin sampling ...

Impact of a 12‐week high‐intensity interval training intervention on cardiac structure and function after COVID‐19 at 12‐month follow‐up

open access: yesExperimental Physiology, Volume 111, Issue 6, Page 2975-2986, 1 June 2026.
Abstract In patients previously hospitalised for COVID‐19, a 12‐week high‐intensity interval training (HIIT) intervention has previously been shown to increase left ventricular mass (LVM) immediately after the intervention. In the present study, we examined the effects of the same HIIT scheme on LVM, pulmonary diffusing capacity, symptom severity and ...

CMR‐derived left ventricular pressure‐volume loops enhance individualized assessment of disease severity and prognosis in pulmonary arterial hypertension in adults

open access: yesPhysiological Reports, Volume 14, Issue 11, June 2026.
Abstract In pulmonary arterial hypertension (PAH), increased pulmonary vascular resistance (PVR) causes right ventricular pressure overload and left ventricular (LV) underfilling. We investigated LV mechanics and their prognostic value in PAH using cardiovascular magnetic resonance (CMR)‐derived LV pressure‐volume (PV) loops.

概率度量空间的性质与集值映象的不动点

open access: yes四川大学学报. 自然科学版, 1988
最近作者在文[3]中对Menger PM—空间中的集值映象及其不动点理论曾作过某些讨论.本文的目的有二:一是建立Menger PM—空间的某些基本性质;二是借助于这些性质进一步研究该空间中的集值映象不动点的存在性问题.本文所得的结果改进和发展了文[3,4,5,7,9,12]中的主要结果.
