Effect of dysprosium on the radiation-shielding features of SiO2–PbO–B2O3 glasses

open access: yesOpen Physics, 2023
In a variety of applications using ionizing radiation, it is essential to ensure the safety of both individuals and equipment. To this end, excellent radiation shielding materials, including glasses and rare earth elements, such as Dy2O3, are currently ...

PHOTON-PHOTON INTERACTIONS [PDF]

open access: yesNuclear Physics A, 1981
Abstract A brief summary of the present status of photon-photon interactions is presented. Stress is placed on the use of two-photon collisions to test present ideas on the quark constituents of hadrons and on the theory of strong interactions.

Overcoming phonon-induced dephasing for indistinguishable photon sources [PDF]

open access: yes, 2012
Reliable single photon sources constitute the basis of schemes for quantum communication and measurement based quantum computing. Solid state single photon sources based on quantum dots are convenient and versatile but the electronic transitions that ...

High energy photon-photon collisions [PDF]

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1995
The collisions of high energy photons produced at an electron-positron collider provide a comprehensive laboratory for testing QCD, electroweak interactions, and extensions of the Standard Model. The luminosity and energy of the colliding photons produced by back-scattering laser beams is expected to be comparable to that of the primary $e^+e ...

Learning cellular morphology with neural networks

open access: yesNature Communications, 2019
Volume electron microscopy data of brain tissue can tell us much about neural circuits, but increasingly large data sets demand automation of analysis. Here, the authors introduce cellular morphology neural networks and successfully automate a range of ...

Compact coupler designs for quantum optical circuits produced by direct UV writing [PDF]

open access: yes, 2009
Integrated planar lightwave circuits (PLCs) provide a promising route to small-scale quantum optical networks [1]. Recent work on quantum logic gates using silica-based PLCs has highlighted the opportunities afforded by the ability to coherently ...

The attenuation of atmospheric Cerenkov photons [PDF]

open access: yes, 2002
Whilst the atmosphere places a limit on the successful applications of many branches of astronomy, it becomes an invaluable tool for the detection of very high energy γ-rays. This thesis is concerned with reducing the systematic uncertainties inherent to

Light source-detector pair positioning to optimize tagging efficiency of focused ultrasound-modulated photons in a backward detection mode

open access: yes, 2023
Focusing Ultrasound (FUS) can be used to modulate diffusing light in tissue. In this method, diffused photons are modulated in the ultrasound focus area.
