Mechanically‐Gated Stochastic Resonance for All‐Optical Acoustic Sensing in Noisy Environments

open access: yesAdvanced Science, EarlyView.
A mechanically‐gated stochastic resonance (MGSR) sensing system is demonstrated, wherein stochastic resonance is enabled by an all‐optical bistable fiber Bragg grating feedback loop and gated by mechanical resonance. Under ambient noise, the system generates bistable outputs satisfying the Kramers escape‐rate condition, yielding signal‐to‐noise ratio ...

Atomic Scale Control of Thermal Conductivity in LaMnO3/SrMnO3 Superlattices

open access: yesAdvanced Electronic Materials, EarlyView.
Interface‐dominated cross‐plane thermal transport in [(LaMnO3)m/(SrMnO3)n]10 superlattices can be controlled by the octahedral rotation/tilt angle φOOR of the MnO6 octahedra, which as well is controlled by the “m/n” ratio. ABSTRACT We report atomic scale structure and phonon thermal transport in (LaMnO3)m/(SrMnO3)n/SrTiO3(100) superlattices (LMO/SMO ...

Self-induced seismicity due to fluid circulation along faults [PDF]

open access: yes, 2013
International audienceIn this article, we develop a system of equations describing fluid migration, fault rheology, fault thickness evolution and shear rupture during a seismic cycle, triggered either by tectonic loading or by fluid injection.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Experimental and numerical simulation on the sliding process of roof rock blocks triggered by dynamic disturbance

open access: yesUnderground Space, 2023
With the excavation of underground opening, the roof rock block may fall under external dynamic disturbance. In this paper, the roof rock mass was simplified as a rock block system composed of trapezoidal rock blocks.

Analysis of Surface Runoff and Ponding Infiltration Patterns Induced by Underground Block Caving Mining—A Case Study

open access: yesApplied Sciences
Surface subsidence induced by underground mining in mining areas significantly alters surface topography and hydrogeological conditions, forming depressions and fissures, thereby affecting regional runoff-ponding processes and groundwater infiltration ...

Numerical Simulation on Damage and Failure Mechanism of Rock under Combined Multiple Strain Rates

open access: yesShock and Vibration, 2018
During underground hard-rock mining, the drilling and blasting method currently remains the most economical excavation method, and the rock may experience a multistrain-rate spectrum under quasi-static, dynamic, and rheological loading conditions and ...

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...
