Sensor detects hydrocarbon oil contaminants in fluid lines [PDF]

open access: yes, 1966
Sensor with ultraviolet light monitors and detects hydrocarbon oil contaminants present in fluid lines. The light causes the oil particles to fluoresce. This light emitted by the oil particle is detected by a photocell which is relatively insensitive to ...

Renormalization of interactions of ultracold atoms in simulated Rashba gauge fields

open access: yes, 2011
Interactions of ultracold atoms with Rashba spin-orbit coupling, currently being studied with simulated (artificial) gauge fields, have nontrivial ultraviolet and infrared behavior.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Increasing the response of PIN photodiodes to the ultraviolet [PDF]

open access: yes, 1972
Solid state device uses sapphire windows and avoids coatings which absorb ultraviolet radiation and ultimately alter detector geometry. Ultimate solution for ultraviolet response is geometry with maximum peripheral area and horizontal field structure to ...

Spitzer Observations of Centaurus A: Infrared Synchrotron Emission from the Northern Lobe

open access: yes, 2006
We present measurements obtained with the Spitzer Space Telescope in five bands from 3.6-24 microns of the northern inner radio lobe of Centaurus A, the nearest powerful radio galaxy. We show that this emission is synchrotron in origin.

Light, including ultraviolet [PDF]

open access: yesJournal of Autoimmunity, 2010
Ultraviolet (UV) light is intricately linked to the functional status of the cutaneous immune system. In susceptible individuals, UV radiation can ignite pathogenic inflammatory pathways leading to allergy or autoimmunity. In others, this same UV radiation can be used as a phototherapy to suppress pathogenic cutaneous immune responses.

Rapid screening of staphylokinase protein variants using an unpurified cell‐free expression system

open access: yesFEBS Open Bio, EarlyView.
An unpurified cell‐free protein synthesis (CFPS) platform enables rapid functional screening of staphylokinase variants. Direct plasminogen‐activation assays performed in microplate format provide real‐time activity readouts, allowing rapid identification and ranking of variants with improved or reduced fibrinolytic activity without protein ...

Pr3+‐Based Visible‐to‐Ultraviolet Upconversion. A minireview

open access: yesAdvanced Physics Research
Optical upconversion materials doped with lanthanides, such as Yb3+‐Er3+, Yb3+‐Ho3+, and Yb3+‐Tm3+ coped systems, have been intensively studied over the past two decades because they can convert long‐wavelength and low‐energy near‐infrared photons into ...

Topical Delivery of Carvedilol Loaded Nano-Transfersomes for Skin Cancer Chemoprevention

open access: yesPharmaceutics, 2020
The β-blocker carvedilol has been shown to prevent skin carcinogenesis in vitro and in vivo. Since systemic absorption of the β-blocker may cause cardiovascular disturbance, we developed a carvedilol loaded transfersome for skin-targeted delivery ...

D = 5 maximally supersymmetric Yang-Mills theory diverges at six loops

open access: yes, 2012
The connection of maximally supersymmetric Yang-Mills theory to the (2,0) theory in six dimensions has raised the possibility that it might be perturbatively ultraviolet finite in five dimensions.
