Artificial Intelligence in Systemic Sclerosis: Clinical Applications, Challenges, and Future Directions

open access: yesArthritis 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.

The performance of wind profiling radars for wind field monitoring in airport areas compared to other remote sensing and in-situ systems

open access: yesMeteorologische Zeitschrift, 1997
Many meteorological services operate ground-based observing systems for wind shear warning. In this study, wind shear data from a 1 GHz profiler at the airport Zurich was compared with data obtained from the ground-based AMETIS 1 system.

Fighting wind shear

open access: yesEos, Transactions American Geophysical Union, 1983
A “coherent and sustained program” of improved radar detection of weather, pilot training, and better communication between pilots and air controllers can greatly reduce the risk of wind shear to airplanes landing or taking off, according to a National Research Council (NRC) committee.Wind shear, characterized by winds rapidly changing direction and ...

Additional acceleration of solar-wind particles in current sheets of the heliosphere [PDF]

open access: yes, 2015
Particles of fast solar wind in the vicinity of the heliospheric current sheet (HCS) or in a front of interplanetary coronal mass ejections (ICMEs) often reveal very peculiar energy or velocity profiles, density distributions with double or triple peaks,

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Identification and Analysis of Wind Shear Within the Transiting Frontal System at Xining International Airport Using Lidar

open access: yesRemote Sensing
The principal factor contributing to the restricted accuracy of wind shear detection resides in the rapid oscillations of the wind field and the intricate characteristics of wind shear. The abrupt alterations in wind speed and direction over a short span
