The Mother of All Bead Furnaces: Testing a Hypothesis about a Natural Draft Bead Furnace

EXARC Journal, 2019
As a part of the ongoing exploration of Viking Era glass bead production, the Dark Ages Re-creation Company (DARC) team perform new pilot experiments on a regular basis.

IMAGING OF FLUOROPHORES IN CHROMATOGRAPHIC BEADS, RECONSTRUCTION OF RADIAL DENSITY DISTRIBUTIONS AND CHARACTERISATION OF PROTEIN UPTAKING PROCESSES

Image Analysis and Stereology, 2010
A new adjustment calculus is presented to determine the true intraparticle distribution of bound protein within chromatographic beads from confocal fluorescence slice series.

Plating by glass-bead peening [PDF]

, 1971
Technique permits plating of primarily metallic substrates with either metals or nonmetals at normal temperature. Peening uses compressed air to apply concurrent streams of small glass beads and powdered plating material to the ...

Fluid-Induced Propulsion of Rigid Particles in Wormlike Micellar Solutions [PDF]

, 2014
In the absence of inertia, a reciprocal swimmer achieves no net motion in a viscous Newtonian fluid. Here, we investigate the ability of a reciprocally actuated particle to translate through a complex fluid that possesses a network using tracking methods

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

One-Bead Microrheology with Rotating Particles

, 2004
We lay the theoretical basis for one-bead microrheology with rotating particles, i.e, a method where colloids are used to probe the mechanical properties of viscoelastic media.

Effects of electromagnetic waves on the electrical properties of contacts between grains [PDF]

, 2007
A DC electrical current is injected through a chain of metallic beads. The electrical resistances of each bead-bead contacts are measured. At low current, the distribution of these resistances is large and log-normal.

Vacuolar transport and function of Saccharomyces cerevisiae sterol ester hydrolase Tgl1

FEBS Letters, EarlyView.
Tgl1, one of yeast sterol ester hydrolases, had been found on the lipid droplets where sterol esters are mainly stored. This study revealed that Tgl1 is transported into the vacuole depending on the ESCRT‐I–III complex, and that it exhibits intra‐vacuolar sterol ester hydrolase activity.

The bead process for beta ensembles

, 2019
The bead process introduced by Boutillier is a countable interlacing of the determinantal sine-kernel point processes. We construct the bead process for general sine beta processes as an infinite dimensional Markov chain whose transition mechanism is ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
