Reconsidering Read and Spontaneous Speech: Causal Perspectives on the Generation of Training Data for Automatic Speech Recognition

Information, 2023
Superficially, read and spontaneous speech—the two main kinds of training data for automatic speech recognition—appear as complementary, but are equal: pairs of texts and acoustic signals. Yet, spontaneous speech is typically harder for recognition. This

H1-antihistamine up-dosing in chronic spontaneous urticaria: patients' perspective of effectiveness and side effects--a retrospective survey study. [PDF]

PLoS ONE, 2011
BACKGROUND: The guidelines recommend that first line treatment of chronic spontaneous urticaria should be second generation non-sedating H(1)-antihistamines with a positive recommendation against the use of old sedating first generation antihistamines ...

Mechanisms of CO and CO₂ Production during the Low-Temperature Oxidation of Coal: Molecular Simulations and Experimental Research

Fire, 2023
The spontaneous combustion of coal caused by oxidation often leads to catastrophic fires. However, the understanding of oxidized carbon gas as a predictor of coal’s spontaneous combustion is still in its infancy.

De Novo Generation of a Unique Cervid Prion Strain Using Protein Misfolding Cyclic Amplification

mSphere, 2017
Substantial evidence supports the hypothesis that prions are misfolded, infectious, insoluble, and protease-resistant proteins (PrPRES) devoid of instructional nucleic acid that cause transmissible spongiform encephalopathies (TSEs).

Optimized hologram generation method for real-time spontaneous manipulation

AIP Advances, 2023
Aided by computer generated holography, holographic optical tweezers enable manipulation of particles and objects with exceptional versatility. The responsiveness of the manipulation is often hindered by the speed of holograph generation, especially when

A Brief Executive Language Screen for Frontal Aphasia

Brain Sciences, 2021
Aphasia assessment tools have primarily focused on classical aphasia type and severity, with minimal incorporation of recent findings that suggest a significant role of executive control operations in language generation.

Phosphosilicate Fiber-Based Low Quantum Defect Raman Fiber Laser with Ultrahigh Spectral Purity

Nanomaterials, 2022
The phosphosilicate fiber-based Raman fiber laser (RFL) has great potential in achieving low-quantum defect (QD) high-power laser output. However, the laser’s performance could be seriously degraded by the Raman-assisted four-wave mixing (FWM) effect and

High-Power Ultraflat Near-Infrared Supercontinuum Generation Pumped by a Continuous Amplified Spontaneous Emission Source

IEEE Photonics Journal, 2015
A high-power ultraflat near-infrared supercontinuum (SC) is generated in a section of photonic crystal fiber (PCF) pumped by an amplified spontaneous emission (ASE) source instead of continuous-wave (CW) and pulsed lasers.

An acoustic analysis of the rhythm of Yemeni Arabic

Journal of Modern Languages, 2019
Previous studies have found that different Arabic dialects display different degrees of stress-timing features forming a continuum that ranges from more stress-timed to less stress-timed Arabic dialects.

Critical Components for Spontaneous Activity and Rhythm Generation in Spinal Cord Circuits in Culture

Frontiers in Cellular Neuroscience, 2020
Neuronal excitability contributes to rhythm generation in central pattern generating networks (CPGs). In spinal cord CPGs, such intrinsic excitability partly relies on persistent sodium currents (INaP), whereas respiratory CPGs additionally depend on ...
