Internal gravity waves in geophysical fluids [PDF]
, 2007 In this second Chapter, we recall some basic notions on stably-stratified flows before focusing on internal gravity wave dynamics. In Section 1, we illustrate the occurence of stably-stratified flows in nature and, in Section 2, we derive the Boussinesq approximation. Except for a very brief presentation of the Kelvin-Helmholtz instability in Section 3,

Multimodal Locomotion of Soft Robots
Advanced Intelligent Systems, EarlyView.This review comprehensively surveys recent advances in multimodal locomotion within soft robotics. Typical locomotion modes are summarized and categorized. Furthermore, the underlying mechanisms enabling multimodal locomotion are discussed and classified into three primary categories: active control‐based, reconfiguration‐based, and environment ...

Worm‐Inspired Soft Robots With Modular Outfit‐Changing for Intelligent Multienvironment Adaptation
Advanced Intelligent Systems, EarlyView.This study proposes a worm‐inspired soft robot capable of locomotion across multiple environments through a modular “outfit‐changing” strategy. The robot integrates pneumatically actuated peristaltic segments with interchangeable external modules, enabling efficient motion on ground surfaces, within pipelines, through granular media, and underwater ...

Wave propagation into the middle atmosphere [PDF]
Recent observations of various types of waves propagating into the middle atmosphere are reviewed. Emphasis is made on the excitation processes in the lower atmosphere and their vertical propagation through the background flow as a function of the ...

An Alternative Approach to Spontaneous Photon Triplets Generation
Advanced Physics Research, EarlyView.Day by day, communication and computing technologies are progressing at a lightning speed, which is particularly true of the quantum version of these technologies (QIST). Increasingly, these technologies are emerging from unusual and sometimes bewildering quantum optical effects, which are based on exotic quantum physical theories.

A study of time-fractional model for atmospheric internal waves with Caputo-Fabrizio derivative.
PLoS ONEThe internal atmospheric waves are gravity waves and occur in the inner part of the fluid system. In this study, a time-fractional model for internal atmospheric waves is investigated with the Caputo-Fabrizio time-fractional differential operator.

Arthritis &Rheumatology, Accepted Article.Objective High intensity conditioning autologous hematopoietic stem cell transplantation (AHSCT) is standard of care for patients with advanced SSc. The role of reduced intensity conditioning (RIC) prior to AHSCT in this population remains unclear. We conducted this study to determine the long‐term outcomes of RIC AHSCT in SSc patients with cardiac ...

Effects of Ion Drag on Ionospheric Gravity Waves in the Presence of a Strong Constant Magnetic Field
AtmosphereA temporally periodic model is presented to describe the vertical profile of internal gravity waves in the F region of the Earth’s ionosphere where the waves are subject to a magnetic force due to the high concentration of ions. The configuration studied
