More Than Effects in Skin: Ultraviolet Radiation-Induced Changes in Immune Cells in Human Blood

open access: yesFrontiers in Immunology, 2021
Cells of the skin and circulation are in constant two-way communication. Following exposure of humans to sunlight or to phototherapy, there are alterations in the number, phenotype and function of circulating blood cells.

A Sunlight-pumped Two-dimensional Thermalized Photon Gas [PDF]

open access: yes, 2022
The Liouville theorem states that the phase-space volume of an ensemble in a closed system remains constant. While gases of material particles can efficiently be cooled by sympathetic or laser cooling techniques, allowing for large phase-space compression, for light both the absence of an internal structure, as well as the usual non-conservation of ...

On-line or Process Viscometry – A Review

open access: yesApplied Rheology, 1999
Process viscometry has many advantages in terms of saving time and gaining more immediate information about a process. However, it can also has disadvantages in terms of compromises that must be made in taking a stream of liquid and passing it through a ...

Micro-optical Tandem Luminescent Solar Concentrators [PDF]

open access: yes, 2017
Traditional concentrating photovoltaic (CPV) systems utilize multijunction cells to minimize thermalization losses, but cannot efficiently capture diffuse sunlight, which contributes to a high levelized cost of energy (LCOE) and limits their use to ...

An examination of the use of rotational viscometers for the quality control of non-Newtonian liquid products in factories

open access: yesApplied Rheology, 2001
A frequent task undertaken by quality-control personnel in typical consumer-goods factories is the measurement of the viscosity of liquid products. The problem often faced in this task is how to strike the correct balance between the complete rheological

The Action of Sunlight [PDF]

open access: yesNature, 1922
IN NATURE of December 15 Sir Oliver Lodge is good enough to refer me to some experiments on the antiseptic action of sunlight which he carried out long ago in association with the late Prof. Marshall Ward. I have not yet been able to see the memoir to which Sir Oliver Lodge refers, but I believe that I am already well acquainted with it, and have been ...

Passive Micron-scale Time-of-Flight with Sunlight Interferometry [PDF]

open access: yesarXiv, 2022
We introduce an interferometric technique for passive time-of-flight imaging and depth sensing at micrometer axial resolutions. Our technique uses a full-field Michelson interferometer, modified to use sunlight as the only light source. The large spectral bandwidth of sunlight makes it possible to acquire micrometer-resolution time-resolved scene ...

Anomalous Reflection Under Ambient Sunlight: Accessing In-Plane Radiation Pressure for Solar Sailing [PDF]

open access: yesarXiv, 2023
Harnessing solar radiation pressure is key to transforming space exploration with multiple low cost sunlight propelled spacecraft to outer reaches of space. By controlling the direction of sunlight momentum transfer new missions and better maneuvering in space can be accessed.

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

open access: yesFEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...
