Time‐of‐Day Impacts Uterine Circadian Rhythms and Response to Oxytocin: Comparison of Uterine Function in Melatonin‐Deficient C57BL/6 Versus Melatonin Proficient CBA/B6 Hybrid Mice

Journal of Pineal Research, Volume 78, Issue 2, March 2026.
ABSTRACT Reaching term gestation requires a complex interplay between the uterus and hormonal signals regulating its contractile profile. Most pregnancy‐associated hormones vary in their overall level of release throughout pregnancy, but also have a circadian release pattern, including progesterone, oxytocin, and melatonin. It remains poorly understood

Three-dimensional advanced numerical approaches to the seismic soil and structural response analyses [PDF]

, 2016
A 3D non-linear finite element approach is developed to study the free-field seismic ground response and the soil-structure interaction (SSI) phenomena at the Lotung site (Taiwan) during the earthquake event occurred on May 20 1986.

Sources of Subseasonal Predictability for Precipitation in South America Based on Model Experiments

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract This study investigates the sources of predictability underlying subseasonal precipitation skill over South America in existing subseasonal prediction systems. Using subseasonal re‐forecasts from the NCAR‐CESM2 model, we demonstrate that significant skill persists even when interannual variability is removed.

A Simple Model for Faraday Waves

, 1996
We show that the linear-stability analysis of the birth of Faraday waves on the surface of a fluid is simplified considerably when the fluid container is driven by a triangle waveform rather than by a sine wave. The calculation is simple enough to use in

The Influence of Interactive Sea Surface Temperatures on Self‐Aggregation in Channel Domain Radiative‐Convective Equilibrium

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Convective self‐aggregation describes the spontaneous organization of convection that occurs in radiative‐convective equilibrium (RCE) simulations. Here, we conduct RCE simulations coupled to 2‐ and 20‐m slab ocean models in a 3D channel domain to assess the influence of interactive sea surface temperatures (SST) on self‐aggregation.

Derivation of the Rayleigh-Plesset equation in terms of volume

, 2007
The most common nonlinear equations of motion for the pulsation of a spherical gas bubble in an infinite body of liquid arise in the various forms of the Rayleigh-Plesset equation, expressed in terms of the dependency of the bubble radius on the ...

Nonlinear Earthquake Response Analysis Using Causal Hysteretic Damping and Extended Rayleigh Damping

Journal of Physics: Conference Series
Abstract In dynamic design, damping considerably influences the response of structures, so it must be set appropriately. Stiffness-proportional damping is generally used as an inherent damping model, but this model tends to overestimate the damping of higher-order modes. Certain models can evaluate the damping of higher-order modes, such

Observation of Topological Chirality Switching Induced Freezing of a Skyrmion Crystal

Advanced Materials, Volume 38, Issue 9, 12 February 2026.
Using Lorentz Transmission electron microscopy, it is shown that in the insulating van der Waals ferromagnet, CrBr3, a magnetic field can cause Bloch skyrmionic bubbles to spontaneously switch their chirality. As achiral type‐II bubbles are an intermediate state, the bubbles rapidly elongate and shrink when switching, thereby inducing a freezing of the

Irreversible magnetization switching using surface acoustic waves

, 2013
An analytical and numerical approach is developped to pinpoint the optimal experimental conditions to irreversibly switch magnetization using surface acoustic waves (SAWs). The layers are magnetized perpendicular to the plane and two switching mechanisms

Rayleigh Damping Coefficients of Laminated Rubber Bearing

International Journal of Recent Technology and Engineering, 2019
In isolating the ground structure and the above ground structure from seismic loads, a significant device called laminated rubber bearing is usually found in structure. The complexity of the material which is made up from a combination of rubber and steel shim plates in alternate layer, has made it difficult to measure damping value.
