An improved algorithm for diffractive optical element with high imaging quality
Journal of the European Optical Society-Rapid PublicationsAn improved algorithm for diffractive optical element (DOE) with high imaging quality is proposed in this paper. The algorithm is designed based on amplitude division between signal and noise regions, further subdivides the noise region into two distinct

An evanescent-field optical microscope [PDF]
, 1991 The classic diffraction limit of resolution in optical microscopy (∼γ/2) can be overcome by detecting the diffracted field of a submicrometre‐size probe in its near field.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

OPTOGALVANIC DETECTION OF OPTICAL PUMPING
Le Journal de Physique Colloques, 1982 We have used an optogalvanic method to detect observables induced by optical pumping in metastable states of neon. As with optical methods signals are obtained due to electronic and nuclear orientation or alignment. Different mechanisms are discussed from which optogalvanic signals related to non-scalar observables may originate. Profiles obtained from

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

A novel inspection method for determining the cosmetic quality of automotive skin panels [PDF]
, 2013 The cosmetic quality of automotive skin panels affects the perceived valuation and quality of an automotive vehicle. The human eye is sensitive to optical distortions caused by geometric deviations and the severity of these distortions is related to ...
