Arthritis Care &Research, EarlyView.Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.

On the Correlation Between the SAR Backscatter Modulation and Surface Waves Orbital Velocity
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingA challenging effect in the retrieval of ocean surface currents from synthetic aperture radar (SAR) is the so-called wave-induced Doppler velocity. This effect arises from the correlation between the modulation of the normalized radar cross section (NRCS)

Doppler Shift Compensation Schemes in VANETs [PDF]
Mobile Information Systems, 2015 Over the last decade vehicle-to-vehicle (V2V) communication has received a lot of attention as it is a crucial issue in intravehicle communication as well as in Intelligent Transportation System (ITS). In ITS the focus is placed on integration of communication between mobile and fixed infrastructure to execute road safety as well as nonsafety ...

On the recoil and Doppler shifts [PDF]
Journal of Modern Optics, 2010 The recoil shift due to the finite mass of an absorbing atom is, when viewed in the right way, simply part of the total Doppler shift. This is true both in the low speed and relativistic limits and also for the reflection of light from a low-mass mirror.

Measurement of the Relativistic Doppler Shift in Neon [PDF]
Physical Review Letters, 1985 The relativistic Doppler shift is measured by the counting of the frequency difference between two cw dye lasers. One laser is locked to a two-photon transition in a fast beam of neon, and the other is locked to the same two-photon transition in thermal neon. The experimental result is compared to the prediction of special relativity.
