Digital optical phase conjugation of fluorescence in turbid tissue [PDF]

open access: yes, 2012
We demonstrate a method for phase conjugating fluorescence. Our method, called reference free digital optical phase conjugation, can conjugate extremely weak, incoherent optical signals. It was used to phase conjugate fluorescent light originating from a

Making beads and bead making: an introduction

open access: yesAzania: Archaeological Research in Africa
Beads are a prominent category of material culture in the African past. Crosscutting their study across temporal periods and geographical areas are some general methodological and theoretical convergences: the categorisation of beads in terms of materials and methods of manufacture, an emphasis on provenance and distribution, and the analysis of beads ...

Pseudomonas aeruginosa Aggregate Formation in an Alginate Bead Model System Exhibits In Vivo-Like Characteristics

open access: yesApplied and Environmental Microbiology, 2017
Alginate beads represent a simple and highly reproducible in vitro model system for diffusion-limited bacterial growth. In this study, alginate beads were inoculated with Pseudomonas aeruginosa and followed for up to 72 h.

Numerical Analysis of Bead Magnetophoresis from Flowing Blood in a Continuous-Flow Microchannel: Implications to the Bead-Fluid Interactions

open access: yesScientific Reports, 2019
In this work, we report a numerical flow-focused study of bead magnetophoresis inside a continuous-flow microchannel in order to provide a detailed analysis of bead motion and its effect on fluid flow.

Forced motion of a probe particle near the colloidal glass transition

open access: yes, 2004
We use confocal microscopy to study the motion of a magnetic bead in a dense colloidal suspension, near the colloidal glass transition volume fraction $\phi_g$.

Active Carboxylic Acid-Terminated Alkanethiol Self-Assembled Monolayers on Gold Bead Electrodes for Immobilization of Cytochromes c [PDF]

open access: yes, 2002
It is extremely difficult to immobilize cytochrome c (cyt c) on carboxylic acid-terminated alkanethiol self-assembled monolayers (HOOC-SAM) on gold bead electrodes prepared in a hydrogen flame.

Detection of HLA Antibodies in Organ Transplant Recipients – Triumphs and Challenges of the Solid Phase Bead Assay

open access: yesFrontiers in Immunology, 2016
This review outlines the development of human leukocyte antigen (HLA) antibody detection assays and their use in organ transplantation in both antibody screening and crossmatching. The development of sensitive solid phase assays such as the enzyme-linked

Testing Roman Glass in the Flame

open access: yesEXARC Journal, 2023
Glass made during the Romano British period was recycled throughout the Late Roman and Early Medieval periods. Studies have shown that British beadmakers of the fifth and early sixth centuries AD made a large proportion of their beads using Roman period ...
