Sub-kHz lasing of a CaF_2 Whispering Gallery Mode Resonator Stabilized Fiber Ring Laser

, 2012
We utilize a high quality calcium fluoride whispering-gallery-mode resonator to stabilize a simple erbium doped fiber ring laser with an emission frequency of 196 THz (wavelenght 1530 nm) to a linewidth below 650 Hz.

Neuromorphic Photonic Processing and Memory With Spiking Resonant Tunneling Diode Neurons and Neural Networks

Advanced Intelligent Systems, EarlyView.
This work shows resonant tunneling diode‐based opto‐electronic spiking neurons enabling fast edge detection in time series, a two‐layer photonic spiking neural network for complex classification, and a depth‐tunable photonic spiking memory system. Neuromorphic computing—modeled after the functionality and efficiency of biological neural systems—offers ...

Cryogenic setup for trapped ion quantum computing

, 2016
We report on the design of a cryogenic setup for trapped ion quantum computing containing a segmented surface electrode trap. The heat shield of our cryostat is designed to attenuate alternating magnetic field noise, resulting in 120~dB reduction of 50 ...

Clinical, Genetic, and Pathologic Variability in Myelodysplastic Syndromes and Precursor Conditions Across Race, Ethnicity, and Sex

American Journal of Hematology, EarlyView.
ABSTRACT The epidemiology of myelodysplastic syndromes/neoplasms (MDS) is challenging to define due to inconsistent reporting, complex diagnostic procedures, and evolving diagnostic criteria. Using the National MDS Natural History Study—a prospective cohort with centrally adjudicated histopathology and genetic variant review—we characterized the ...

Navigating the Post‐BCMA/GPRC5D Landscape: Efficacy of Selinexor, Bortezomib, and Dexamethasone After Sequential Immunotherapy Failure in Penta‐Refractory Multiple Myeloma—A Multicenter Analysis

American Journal of Hematology, EarlyView.
ABSTRACT Patients with relapsed/refractory multiple myeloma (RRMM) who are penta‐drug refractory, defined as resistant to two proteasome inhibitors, two immunomodulatory agents, and an anti‐CD38 monoclonal antibody, face a dismal prognosis, particularly after exposure to T‐cell–redirecting therapies.

Direct Measurement of the Proton Magnetic Moment

, 2012
The proton magnetic moment in nuclear magnetons is measured to be $\mu_p/\mu_N \equiv g/2 = 2.792\,846 \pm 0.000\,007$, a 2.5 ppm (parts per million) uncertainty.

The Clinical Spectrum and Neurodevelopmental Pathogenesis of KPTN‐Related Disorder in a Mouse Model

Annals of Neurology, EarlyView.
Objective Pathogenic variants in Kaptin (KPTN) cause KPTN‐related disorder (KRD). KPTN modulates mTOR signaling activation within the KICSTOR complex in response to cellular amino acid levels. We define the clinical spectrum and investigate the developmental pathogenesis of KRD.

Frequency Measurements of Superradiance from the Strontium Clock Transition

Physical Review X, 2018
We present the first characterization of the spectral properties of superradiant light emitted from the ultranarrow, 1-mHz-linewidth optical clock transition in an ensemble of cold ^{87}Sr atoms. Such a light source has been proposed as a next-generation

Frequency stability improvement for piezoresistive micromechanical oscillators via synchronization

AIP Advances, 2017
Synchronization phenomenon first discovered in Huygens’ clock shows that the rhythms of oscillating objects can be adjusted via an interaction. Here we show that the frequency stability of a piezoresistive micromechanical oscillator can be enhanced via ...
