Whirling domains of geometric patterns seen after pressure on the eyeball, known as phosphenes, have been observed for over 2000 years, but their source of origin remains a mystery. The study tested the feasibility of phosphene generation in the cortex through the action of decreased retinal input. This decrease is elicited by the retinal ischemia that accompanies prolonged pressure. A simple W...

The analysis of circulating tumor cells (CTCs) is an emerging field for estimating the metastatic relapse and tumor burden of cancer patients. However, the isolation of CTCs is still challenging due to their ambiguity, rarity, and heterogeneity. Here, we present an anti-CD45 antibody based dual-patterned immunofiltration (DIF) device for the enrichment of heterogeneous CTC subtypes by effective...

An experiment in forced vibration was conducted to study the fluidinduced rotordynamic force on an impeller whirling along a trajectory eccentric to its undeflected position. The prescribed whi l trajectory of the rotor is a circular orbit of a b e d radius. The force measured is a combination of a steady radial force due to volute asymmetries and an unsteady force due to the eccentric motion o...

Fluctuating hearing loss and vertigo are the typical presentations of Meniere's disease. However, it is unusual that fluctuating hearing loss and vertigo are caused by vertebral artery occlusion or cerebral infarction. Here, we described the case of a 54-year-old male patient with hypertension and diabetes mellitus who presented with fluctuating hearing loss in his left ear and severe whirling-...

How abstract are the ideas required to address biological movement? Consider the question posed by Arthur Winfree (1987, p. 253), the foremost theoretician on temporal order in biology and chemistry: “How does a gymnast calculate forces and rates for hundreds of muscles with millisecond precision while whirling from one maneuver to the next?” For Winfree, the answer is not forthcoming in the la...

In the paper, a new low-order parametric force model for an electrical machine with eccentric rotor is developed and verified. The model is designed for an electrical machine equipped with both the parallel stator windings and rotor cage, and, therefore, accounts for the equalising currents in the stator and rotor windings separately and also for their influence on each other. Furthermore, the ...

Myxobolus cerebralis is the causative agent of whirling disease in salmonid fishes. In 2016, this invasive parasite was detected Alberta, Canada, for first time, initiating a comprehensive 3 yr monitoring program to assess where had spread within province. As part program, qPCR-based test developed facilitate detection environmental stages M. and from oligochaete host, Tubifex tubifex. During ~...
