Confining sound is of significant importance for the manipulation and routing acoustic waves. We propose a Helmholtz resonator (HR) based subwavelength channel formed at interface two metamaterials, this purpose. The confinement quantified through (i) substantial reduction pressure, (ii) an increase in specific impedance (defined by ratio local pressure to velocity) - very large value outside c...

The photo shows the Isolator which was developed in 1925 by Hugo Gernsback to treat conditions such as attention-deficit hyperactivity disorder. 1 The patient would wear the diving bell-like apparatus. Outside sound was excluded and the eye holes 'focussed' one's attention on the task at hand. The Isolator came with its own oxygen supply to ensure the patient did not suffocate during treatment.

This paper provides valuable information about the functional aspects of the heart and cardiovascularsystem (CVS). The features extracted in this work by considering the heart signal as a sound signal can assist in formulating better techniques to diagnose cardiac disorder. The aim of this research is to develop signal analysis methods and provide a computerized cardiac auscultation system. In ...

A child was referred for an audiologic evaluation, to include auditory brainstem evoked response testing, due to inconsistent responses to sound and delayed speech and language development. Results were characteristic of auditory neuropathy. In view of subsequent decline in motor function, a genetics evaluation was conducted, revealing a mitochondrial disorder. A brief overview of mitochondrial...

Background: “Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections”, or PANDAS, is a syndrome characterized by acute-onset obsessive-compulsive disorder (OCD) and/or tics accompanied by the neuropsychiatric symptoms. This case is reported because of its rarity. Case report: A 6.5-year-old boy with swollen tonsils, high-grade fever and rash was admitted to Ami...

Tourette's syndrome (TS) is a neurodevelopmental disorder typically defined by multiple motor tics and at least one sound tic, beginning in childhood or in adolescence. Handwriting is one of the most impaired school activities for TS patients because of the presence of tics that hamper learning processes. In this paper, we present a case of handwriting tics in a TS patient highlighting the main...
