Magnetic phase diagram of doped CMR manganites

open access: yes, 2002
The magnetic phase diagram of the colossal magnetoresistance (CMR) manganites is determined based on the Hamiltonian incorporating the double-exchange (DE) interaction between degenerate Mn $e_g$ orbitals and the antiferromagnetic (AF) superexchange ...

„Wir machen blau“ – Untersuchung der Inhaltsstoffe und Herstellung eines „Magischen Klebstiftes“ mit Farbwechseleffekt

open access: yesCHEMKON, EarlyView.
Der Klebestift UHU® „stic Magic Blue“ zeigt einen markanten Farbwechsel: Während die Klebemasse anfangs intensiv blau gefärbt ist, wird diese einige Zeit nach dem Auftragen farblos. Die Ursachen des Farbwechsels wurden mithilfe einfacher Experimente untersucht, die sich besonders für den Chemieunterricht eignen. Bei der farbgebenden Substanz handelt es

FastVentricle: Cardiac Segmentation with ENet

open access: yes, 2017
Cardiac Magnetic Resonance (CMR) imaging is commonly used to assess cardiac structure and function. One disadvantage of CMR is that post-processing of exams is tedious. Without automation, precise assessment of cardiac function via CMR typically requires

Transthyretin amyloid cardiomyopathy: Literature review and red‐flag symptom clusters for each cardiology specialty

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 955-967, April 2025.
Abstract Wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating ...

Prognostic role of high‐sensitivity cardiac troponin T in patients with cardiac sarcoidosis: insights from ILLUMINATE‐CS

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 869-878, April 2025.
Abstract Aims The prognostic role of high‐sensitivity cardiac troponin T (hs‐cTnT) as a biomarker in patients with cardiac sarcoidosis (CS) has yet to be fully determined, especially when compared with B‐type natriuretic peptide (BNP). Methods and Results In this post‐hoc analysis of the ILLUMINATE‐CS (ILLUstration of the Management and prognosIs of ...

Effects of lattice distortion and Jahn–Teller coupling on the magnetoresistance of La0.7Ca0.3MnO3 and La0.5Ca0.5CoO3 epitaxial films [PDF]

open access: yes, 1997
Studies of La0.7Ca0.3MnO3 epitaxial films on substrates with a range of lattice constants reveal two dominant contributions to the occurrence of colossal negative magnetoresistance (CMR) in these manganites: at high temperatures (T → TC, TC being the ...
