Effect of noise-induced wavelength fluctuation in tunable diode lasers on narrow-linewidth absorption measurements.

Tunable diode laser absorption spectroscopy is being widely used to make sensors for diagnostic purposes in various engineering applications. Since the wavelength of many diode lasers used in such sensors is sensitive to the driving current, even noise as small as a few μA in the driving current can cause a wavelength fluctuation of ∼±0.5  pm, which is large enough to interfere with sensitive absorption measurements. Although these fluctuations are small, they can cause significant systematic error ...

Orphan drugs: major development challenges at the clinical stage.

Biotechnology has provided powerful tools to assist in research and development (R&D) for rare diseases. However, orphan drug development presents several major challenges and obstacles, such as low disease prevalence, disease severity, small and heterogeneous patient populations, difficulties in patient recruitment, and limited knowledge of the natural history of disease, among others. Several strategies can be used to plan for and overcome these clinical and regulatory challenges, namely improved clinical...

Mechanistic machine learning: how data assimilation leverages physiologic knowledge using Bayesian inference to forecast the future, infer the present, and phenotype.

We introduce data assimilation as a computational method that uses machine learning to combine data with human knowledge in the form of mechanistic models in order to forecast future states, to impute missing data from the past by smoothing, and to infer measurable and unmeasurable quantities that represent clinically and scientifically important phenotypes. We demonstrate the advantages it affords in the context of type 2 diabetes by showing how data assimilation can be used to forecast future glucose valu...

Attitudes of publics who are unwilling to donate DNA data for research.

With the use of genetic technology, researchers have the potential to inform medical diagnoses and treatment in actionable ways. Accurate variant interpretation is a necessary condition for the utility of genetic technology to unfold. This relies on the ability to access large genomic datasets so that comparisons can be made between variants of interest. This can only be successful if DNA and medical data are donated by large numbers of people to 'research', including clinical, non-profit and for-profit res...

Floquet Engineering of Multiorbital Mott Insulators: Applications to Orthorhombic Titanates.

We consider driving multiorbital Mott insulators using laser radiation. We derive general expressions for periodically driven spin-orbital models using time-dependent perturbation theory in the strong interaction limit. We show that the effective exchange interactions of the Floquet spin-orbital Hamiltonian are highly tunable via variations of the frequency, amplitude, and polarization of the laser. We also take the effect of a finite bandwidth of excitations into account and study possible heating effects....
