Gaussian pulse dynamics in gain media with Kerr nonlinearity

, 2011
Using the Kantorovitch method in combination with a Gaussian ansatz, we derive the equations of motion for spatial, temporal and spatiotemporal optical propagation in a dispersive Kerr medium with a general transverse and spectral gain profile.

Spatiotemporal dynamics of a passively mode-locked Nd:GdVO₄laser

Optics Express, 2007
By examining beam patterns, temporal pulse forms, and radio-frequency spectra as functions of resonator configuration and pump power, we found that a passively mode-locked Nd:GdVO4 laser exhibited four main regimes of operation that were single-transverse-mode Q-switched mode locking (QSML), single-transverse-mode continuous-wave mode locking (CWML ...

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 ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Spatiotemporal dynamics and optical vortices in a photorefractive phase-conjugate resonator [PDF]

A truncated modal expansion approach is used to study the spatiotemporal dynamics of a phase-conjugate resonator as a function of Bragg detuning. The numerical results reveal a rich variety of behaviors.

Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

Biological Reviews, EarlyView.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

Dynamics of bubble absorption over porous membranes in an immersed medium

Droplet, EarlyView.
The dynamics of a bubble interacting with a flat, porous superhydrophobic membrane underwater has been illustrated. Abstract Porous superhydrophobic (SHP) membranes are gaining considerable attention due to their excellent underwater absorption and drag reduction properties. They exploit the Cassie‒Baxter state of wetting to remove the bubble in a fast
