American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Substantial data supports the use of rapid exome and genome sequencing (rES/rGS) in Neonatal Intensive Care Units (NICU), but fewer studies have examined the impact of rES/rGS in other pediatric critical care units. We evaluated the impact on diagnostic yield and time to diagnosis following a single‐center hospital policy change allowing ...

A chip-based optoelectronic-oscillator frequency comb
eLightMicroresonator-based Kerr frequency combs (“Kerr microcombs”) constitute chip-scale frequency combs of broad spectral bandwidth and repetition rate ranging from gigahertz to terahertz.

Single ion fluorescence excited with a single mode of an UV frequency comb
Nature Communications, 2017 Frequency combs are useful tools in high precision measurement including atomic transitions and atomic clocks. Here the authors demonstrate direct frequency comb spectroscopy to shorter wavelengths by probing a transition frequency in a trapped Mg+ ion ...

, 2006 We have developed the full theory of a synchronously pumped type I optical parametric oscillator (SPOPO). We derive expressions for the oscillation threshold and the characteristics of the generated mode-locked signal beam. We calculate the output quantum fluctuations of the device, and find that, in the degenerate case (coincident signal and idler set

A Fast Method for Selecting Bio Sourced Materials of Interest in a Candle Formulation
Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT As consumer demand shifts towards more sustainable and nontoxic alternatives, the candle industry is exploring unconventional bio‐based and recycled materials as substitutes for paraffin. Four raw materials, that is rice bran wax (RBW), sugarcane wax (SCW), hydrogenated rapeseed oil (HRO), and waste cooking oil (WCO) were assessed based on ...

Physical Review Research, 2020 We report on experimental and theoretical demonstrations of an optical comb spectrum based on a combination of cascaded stimulated Raman scattering and four-wave mixing mediated by Raman-induced nonresonant Kerr-type nonlinearity.

Electro-optic dual-comb interferometry over 40-nm bandwidth
, 2016 Dual-comb interferometry is a measurement technique that uses two laser frequency combs to retrieve complex spectra in a line-by-line basis. This technique can be implemented with electro-optic frequency combs, offering intrinsic mutual coherence, high ...

We identify a new class of time periodic attractor solutions in scalar field cosmology, which we term Cosmological Frequency Combs (CFC). These solutions arise in exponential quintessence models with a phantom matter background and exhibit coherent phase-locked oscillations in the scalar field's normalized variables.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...
