As an advanced heat exchanger for aero-turbine applications, a tubular-type was developed. To ensure the optimum performance of exchanger, it is necessary to assess structural integrity tubes, considering assembly processes such as brazing. In this study, fatigue tests at room temperature and 1000 K were performed 0.135 mm-thick alloy 625 tubes (outer diameter 1.5 mm), which brazed grip specime...

Prior studies examining racial disparities in cutaneous melanoma have found that Black patients (BPs) present at a later stage than non-Hispanic White (NHWPs). However, previous not assessed whether there are differences the thickness of primary lesions between BPs and NHWPs, nor they examined detail socioeconomic status (SES) body location (PBL) as potential explanations for noted. This study ...

The surface of Inconel 625, a nickel-base alloy, was strengthened by vacuum electron beam scanning technology. evolution its microstructure analyzed backscatter diffraction (EBSD) and the friction wear tester (RETC). results show that FCC phase in 625 alloy is stripped islanded after treatment. austenite texture type changes finally forms typical cubic with certain strength S texture. With incr...

We here present a modeling study of the chromatin fiber functional organization. Multi-scale modeling is required to unravel the complex interplay between the fiber and the DNA levels. It suggests plausible scenarios, including both physical and biological aspects, for fiber condensation, its targeted decompaction, and transcription regulation. We conclude that a major role of the chromatin fib...

Since their first demonstration some 25 years ago, thermally poled silica fibers have been used to realize device functions such as electro-optic modulation, switching, polarization-entangled photons, and optical frequency conversion with a number of advantages over bulk free-space components. We have recently developed an innovative induction poling technique that could allow for the developme...
