Under tension, confined elastic layers can exhibit various modes of mechanical instabilities, including cavitation, fingering and fringe instabilities. While the cavitation has been extensively studied, the fingering and fringe instabilities have not been well understood, and the relations and interactions of these instabilities have not been explored yet. In this paper, we systematically study...

A good piano fingering is essential for pianists to play a piece fluently. Some examples of algorithms to generate a piano fingering automatically can be found in the literature. However, the existing methods can only generate fingerings for small, monophonic piano pieces for the right hand, minimising the difficulty. In this paper, we develop a variable neighbourhood search (VNS) algorithm tha...

Using air to displace a viscous fluid contained in a Hele-Shaw cell can create a fingering pattern at the interface between the fluids if the capillary number exceeds a critical value. This Saffman-Taylor instability is revisited for the inverse case of a viscous fluid displacing air when partially wettable hydrophilic particles are lying on the walls. Though the inverse case is otherwise stabl...

We present an experimental study of the fingering patterns in a Hele-Shaw cell occurring when a gel-like material forms at the interface between aqueous solutions of a cationic surfactant (cetyltrimethylammonium bromide) and an organic salt (salicylic acid), two solutions known to form a highly elastic wormlike micellar fluid when mixed homogeneously. A variety of fingering instabilities are ob...

Music lessons are a repetitive process of giving feedback on a student’s performance techniques. The manner in which performance skills are improved depends on the particular instrument, and therefore, it is important to consider the unique characteristics of the target instrument. In this paper, we investigate the common mistakes of beginner flute players and propose a hierarchical approach to...

This paper presents a frequency-domain technique for estimating the plucking point on a guitar string from an acoustically recorded signal. It also includes an original method for detecting the fingering point, based on the plucking point information.

Pasteurella multocida is a rare cause of neonatal bacterial meningitis. We describe such a case and verify two household cats as the source of infection using repetitive-element PCR (rep-PCR) molecular fingering.
