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.

A research about the effect of sound waves on standing waves by using Ruben’s Tube. [PDF]
, 2009 Sound waves are longitudinal waves. In a longitudinal wave, particles of medium vibrations are paralel to the direction of propagation of the wave. Using this nature of sound waves, Ruben’s tube has been created. In Ruben’s Tube, by the help of pressure,

Analytical Investigation of the Effects of Topographic Irregularities on Peak Pressure due to Blast Waves [PDF]
Journal of Structural and Construction Engineering, 2015 Effects of propagation and scattering of high pressure waves same as blast waves are always interested for researchers. In this paper, the additional air pressure due to blast waves near topographic irregularities is considered.

Grid metastructures for ultrabroadband acoustic cloaking
AIP Advances, 2013 Structural grids (grid metastructures) supporting discrete pressure waves similar to the pressure waves in continuous media are considered. The grids consist of links capable of transmitting longitudinal pressure waves and nodes providing equal pressures

Simulation of thermoacoustic waves by a pressure-based algorithm for compressible flows
, 2012 A modified SIMPLEC method which can solve compressible flows at low Mach number is introduced and used to study thermoacoustic waves induced by a rapid change of temperature at a solid wall and alternating-direction flows generated by thermoacoustic ...

Probing the relationship between electromagnetic ion cyclotron waves and plasmaspheric plumes near geosynchronous orbit [PDF]
, 2010 Plasmaspheric plumes created during disturbed geomagnetic conditions have been suggested as a major cause of increased occurrences of electromagnetic ion cyclotron (EMIC) waves at these times.

Anorectal Dysfunction in Systemic Sclerosis: Clinical Phenotypes and Functional Patterns
Arthritis Care &Research, EarlyView.Objective The aim of this study was to characterize specific physiologic defects in anorectal dysfunction in systemic sclerosis (SSc) using anorectal manometry (ARM), evaluate associations with gastrointestinal (GI) and extraintestinal clinical phenotypes, and explore potential serologic markers for risk stratification.
