Climatological Gravity Waves in the Middle and Upper Atmosphere of Mars Based on ACS/TGO Observations

open access: yesThe Astrophysical Journal, 2023
Gravity waves (GWs) are important for the vertical coupling of the Martian atmosphere. The middle atmosphere is the key region where GWs propagate to the upper thermosphere and generate momentum and energy exchange, but the knowledge of middle-atmosphere

Internal waves

open access: yesEos, Transactions American Geophysical Union, 1971
Progress in the United States in the study of oceanic internal waves has continued in both observational and theoretical areas. Whereas the theories are becoming more sophisticated all the time, their bearing on the observations remains peripheral and speculative.

Interaction of interfacial and internal waves

open access: yesFluid Dynamics Research, 1988
Reflection of internal waves at an interface between the mixed layer and a stratified fluid under the layer is investigated experimentally. Reflection coefficients of the internal waves and transmission coefficients of interfacial waves are obtained for the case in which the interfacial waves propagate along the interface. In order to reveal the energy

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.

Investigation of internal gravitational waves by an infrared camera of the entire sky over the territory of Yakutia

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2022
Internal gravitational waves are space-time fluctuations of air masses in the atmosphere. In addition to the longitudinal component, they also have a transverse component, which distinguishes them from ordinary acoustic waves.

Stokes waves modulation by internal waves [PDF]

open access: yesGeophysical Research Letters, 2007
The effect of subsurface currents induced by internal waves on nonlinear surface waves is theoretically analyzed. An analytical and numerical solution of the modulation equations are found under the conditions close to the group velocity resonance.

Rheumatoid Arthritis and Coronary Artery Calcium Progression: A Case Cohort Analysis From ELSA‐Brasil

open access: yesArthritis Care &Research, EarlyView.
Objective To investigate the association between rheumatoid arthritis (RA) and coronary artery calcium (CAC) prevalence, incidence, and progression over four years in adults without prior cardiovascular disease. Methods A case‐cohort study within the Brazilian Longitudinal Study of Adult Health (ELSA‐Brasil) included 585 participants (86 patients with ...

Anorectal Dysfunction in Systemic Sclerosis: Clinical Phenotypes and Functional Patterns

open access: yesArthritis 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.

To rate spread internal gravity waves

open access: yesНаука. Инновации. Технологии, 2022
Sometimes mistakenly assumed that gravity waves only have a frequency equal to Brunt - Vaisala. However, there is a wide range of wave frequencies are less than this value.

On the conditions of internal tide wave generation along the west coast of Mexico

open access: yesCiencias Marinas, 1996
Baines’ (1982) model was used to calculate the energy flux of the barotropic M2 waves to internal waves. An estimation of their amplitudes in a section where the continental shelf declines was calculated.
