Uncertainty of the 2D Resistivity Survey on the Subsurface Cavities

open access: yesApplied Sciences, 2021
We examined the uncertainty of the two-dimensional (2D) resistivity method using conceptual cavity models. The experimental cavity study was conducted to validate numerical model results.

Community-acquired infection presenting as a cavitary lung disease in an immunocompetent patient [PDF]

open access: yesYeungnam University Journal of Medicine, 2020
Achromobacter xylosoxidans is a gram-negative bacterium that can oxidize xylose. It is commonly found in contaminated soil and water but does not normally infect immunocompetent humans. We report a case of a cavitary lung lesion associated with community-

Combustion Characteristics of a Supersonic Combustor with a Large Cavity Length-to-Depth Ratio

open access: yesAerospace, 2022
The combustion characteristics of a hydrogen-fueled supersonic combustor featuring a large cavity length-to-depth ratio (i.e., 11) were examined by performing experimental trials while varying the fuel injector positions and equivalence ratios.

Tripartite entanglement and entanglement transfer in a hybrid cavity magnomechanical system

open access: yesOpen Physics, 2023
We propose to realize bipartite and tripartite entanglements transfer in a cavity magnomechanical system consisting of a microwave cavity with an yttrium iron garnet (YIG) sphere and a silicon-nitride membrane in it.

Cavity Click Chemistry: Cavity-Catalyzed Azide–Alkyne Cycloaddition

open access: yesThe Journal of Physical Chemistry A, 2023
Click chemistry, which refers to chemical reactions that are fast, selective, and with high product yields, has become a powerful approach in organic synthesis and chemical biology. Due to the cytotoxicity of the transition metals employed in click chemistry reactions, a search for novel metal-free alternatives continues.

Influence of cavity lifetime on high-finesse microcavity two-photon absorption photodetectors [PDF]

open access: yes, 2007
For optical pulse incidence as compared with continuous-wave incidence, the enhancement of two-photon absorption inside a high-finesse planar microcavity is reduced, the pulse inside the cavity and the cavity spectrum are broadened.

Cavity opto-mechanics

open access: yes2008 Conference on Lasers and Electro-Optics, 2007
The coupling of mechanical and optical degrees of freedom via radiation pressure has been a subject of early research in the context of gravitational wave detection. Recent experimental advances have allowed studying for the first time the modifications of mechanical dynamics provided by radiation pressure.

Investigating the Design and Simulation of a Tunable Optical Filter Based on Photonic Crystal Using Selective Optofluidic Infiltration [PDF]

open access: yesJournal of Optoelectronical Nanostructures, 2022
In this paper an optical filter based on 2D hexagonal photonic crystals that is suitable for the third window of optical communications is proposed. The structure consists of two waveguides including one L4 resonant cavity created by removing 4 holes ...

Cavity and entrance pore development in ant plant hypocotyls

open access: yesFrontiers in Plant Science, 2023
Some genera of Rubiaceae in South-eastern Asia are known as typical ant plants. They have large domatia, which form in well-developed hypocotyls in which ants nest.

Motion Induced Radiation from a Vibrating Cavity [PDF]

open access: yes, 1996
We study the radiation emitted by a cavity moving in vacuum. We give a quantitative estimate of the photon production inside the cavity as well as of the photon flux radiated from the cavity. A resonance enhancement occurs not only when the cavity length
