Pump‐Probe Imaging of Ultrafast Laser Percussion Drilling of Glass in Single Pulse, MHz‐ and GHz‐Burst Regimes

open access: yesAdvanced Materials Interfaces
A pump‐probe shadowgraphy study of femtosecond laser percussion drilling on glass samples is reported applying three different operating regimes, which are the standard repetitive single pulse, the MHz‐ and the GHz‐burst modes.

High amplitude sinusoidal pressure generator [PDF]

open access: yes, 1970
Generator is an inlet-area-modulated, gas-flow-through device utilizing hydrogen gas and a rotating disk for operation. Design enables generator to produce pressure oscillations as high as 120, 18, and 12 percent of the mean chamber pressure at ...

Thermal amplitude test [PDF]

open access: yesImmunohematology, 2013
Abstract The thermal amplitude test is performed to determine the reactivity of a cold autoantibody at varying temperatures: 4°C, 22°C, 30°C, and 37°C. Cold autoantibodies that are reactive at temperatures greater than 30°C have the potential to be clinically significant regardless of the antibody titer.

Acoustic Measures Capture Speech Dysfunction in Spinocerebellar Ataxia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Spinocerebellar ataxias (SCA) are hereditary cerebellar degenerative disorders with a common feature of dysarthria, involving impaired phonatory and articulatory control of speech, thereby affecting social communication. In this study, we investigated whether acoustic measures could objectively measure speech dysfunction and identify

Algebras for amplitudes [PDF]

open access: yesJournal of High Energy Physics, 2012
Abstract Tree-level amplitudes of gauge theories are expressed in a basis of auxiliary amplitudes with only cubic vertices. The vertices in this formalism are explicitly factorized in color and kinematics, clarifying the color-kinematics duality in gauge theory amplitudes.

Age‐Related Characteristics of SYT1‐Associated Neurodevelopmental Disorder

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We describe the clinical manifestations and developmental abilities of individuals with SYT1‐associated neurodevelopmental disorder (Baker‐Gordon syndrome) from infancy to adulthood. We further describe the neuroradiological and electrophysiological characteristics of the condition at different ages, and explore the associations ...
