Disks of Stars in the Galactic Center Triggered by Tidal Disruption Events

The Astrophysical Journal Letters, 2022
Abstract In addition to a supermassive black hole (SMBH), the central parsec of the Milky Way hosts over 100 massive, high-velocity young stars whose existence, and organization of a subset of them in one, or possibly two, misaligned disks, is puzzling. Due to a combination of low medium density and strong tidal forces in the vicinity of

Periodic tidal forcing and seismic response in the diverse tectonic settings of the Andaman–Sumatra subduction zone, Sunda Arc

Frontiers in Earth Science
Tidal modulation of seismicity is globally reported in fluid-rich environments of hydrothermal systems, particularly in oceanic or coastal settings. Specifically, the short-period and high-amplitude stress variations caused by ocean tidal loading within ...

Weak faults at megathrust plate boundary respond to tidal stress

Earth, Planets and Space, 2021
Lateral spatial variations of weak portions at the plate boundary in subduction zones have been estimated primarily by the distribution of slow earthquakes mainly occurring around seismogenic zones.

Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

Advanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Tidal turbulence in medium depth water, primarily a model study

, 2023
Tidal energy is considered to be one important future source of renewable energy. There is presently a strong development in new technology, and there is an emerging need to e.g., describe the turbulence intensity and its characteristics in a tidal ...

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Tremor burst and triggering processes in Cascadia after the 2022 Hunga Tonga-Hunga Ha’apai volcanic eruption

Geomatics, Natural Hazards & Risk
Episodic Tremors and Slip (ETS) are highly susceptible and sensitive to external stress perturbations. The tidal and remote triggering phenomena of tremors are well-documented globally, however, the significance of the delayed triggering mechanism ...

Different Fault Response to Stress during the Seismic Cycle

Applied Sciences, 2021
Seismic prediction was considered impossible, however, there are no reasons in theoretical physics that explicitly prevent this possibility. Therefore, it is quite likely that prediction is made stubbornly complicated by practical difficulties such as ...

Tidally triggered galaxy formation. II - Galaxy number counts [PDF]

The Astrophysical Journal, 1993
A model is presented for the evolution of the galaxy luminosity function in which the distribution of the galaxy masses, star formation time scales, and star formation turn-on redshifts is derived from the initial power spectrum of density fluctuations. The mass function of galaxy halos is very steep at low masses.

Synchronization‐Dissipation in the Cardiorespiratory System

Advanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.
