Amplitude Effect in Cepheid Variables [PDF]
Nature, 1945 IN the interesting review1 of the pulsation theory in his George Darwin Lecture of 1943 before the Royal Astronomical Society, Prof. S. Rosseland has indicated the importance of unharmonic oscillations in explaining the Cepheid characteristics, and brought out the effect of the amplitude in lengthening the pulsational period, pointed out by Kluyver2 in

Some Aspects of Variable Amplitude Fatigue [PDF]
International Journal of Metallurgy and Metal Physics, 2019 Fatigue crack growth behavior of selected aluminum alloys under variable amplitude loading is discussed in this study, based principally on experimental observations. The tests include single overloads tests in different environments, and tests using an aircraft wing loading spectrum.

Three-graviton amplitude in Berkovits–Vafa–Witten variables [PDF]
Physics Letters B, 2002 We compute the three-graviton tree amplitude in Type IIB superstring theory compactified to six dimensions using the manifestly (6d) supersymmetric Berkovits-Vafa-Witten worldsheet variables. We consider two cases of background geometry: the flat space example R6xK3, and the curved example AdS3xS3xK3 with Ramond flux, and compute the correlation ...

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

A two-step multiaxial racetrack filter algorithm for non-proportional load histories [PDF]
Fracture and Structural Integrity, 2017 The recently proposed multiaxial racetrack filter (MRF) is able to deal with general non-proportional multiaxial load histories. While only requiring a single user-defined scalar filter amplitude, the MRF is able to synchronously eliminate non-damaging ...

Sulla stima della vita a fatica di giunti saldati soggetti a carichi multiassiali ad ampiezza variabile [PDF]
Fracture and Structural Integrity, 2009 Nel presente articolo viene proposta una nuova metodologia di progettazione a fatica, basata sull’utilizzo del metodo delle Curve di Wöhler Modificate, per la previsione della vita a fatica di giunzioni saldate, sia in acciaio che in alluminio, soggette

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
