RNA Sequencing Resolves Cryptic Pathogenic Variants in Mitochondrial Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Mitochondrial diseases are the most common inherited metabolic disorders, characterized by pronounced clinical and genetic heterogeneity that complicates molecular diagnosis. Although DNA‐based sequencing approaches have become standard in genetic testing, up to half of patients remain without a definitive diagnosis.

Note: Parametric tuning of the Helmholtz coil and its optimal designs with thick winding pairs
AIP Advances, 2018 Thick winding pairs are generally utilized in high-power Helmholtz coil systems, where the coil-heating and insulation are usually of concern for their field uniformity.

THE DEBT OF OTOLOGY TO HELMHOLTZ. [PDF]
JAMA: The Journal of the American Medical Association, 1902 The influence of Helmholtz upon otology is almost incalculable, although signalized by no instrument like the ophthalmoscope with its epoch-making application and its huge clinical field. Reflectors of various kinds to illuminate the aural, nasal and pharyngeal cavities had been somewhat used before his day and received but moderate impulse directly ...

Resonance frequencies and sound absorption of Helmholtz resonators with multiple necks
Applied Acoustics, 2019 A new analytical model is proposed to calculate the resonance frequency and the input impedance of a Helmholtz resonator with multiple necks. Such resonators occur in practice, for example, when leaks are introduced as additional necks inside the wall of

Nonlinear interfaces: intrinsically nonparaxial regimes and effects [PDF]
, 2009 The behaviour of optical solitons at planar nonlinear boundaries is a problem rich in intrinsically nonparaxial regimes that cannot be fully addressed by theories based on the nonlinear Schrödinger equation.
