Design of active magnetic bearing rotors and their control method for passing through fourth bending critical speed

Mechanical Engineering Journal, 2019
These days, centrifugal compressors and other industrial turbomachines tend to be faster, downsized, and reduced in cost. If a technology can be established for operation of machines over higher critical speed using an active magnetic bearing, the number

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Pressure transient analysis for detecting leakages along active and abandoned wells

Scientific Reports
Leakage out of the target formation is a major risk associated with subsurface wellbores. This study explores feasibility of leakage detection with pressure transient analysis (PTA) in multiple potential leakage scenarios, including induced fractures and

A Comparative Evaluation of Active Cooling and Passive Insulation Technologies for Thaw Mitigation During Permafrost Drilling

Applied Sciences
Permafrost thawing induced by heat transfer from circulating drilling fluid poses a significant threat to wellbore integrity and drilling safety in Arctic hydrocarbon exploration. The absence of clear application boundaries for the two primary mitigation

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
