The optimal design of a binaural sparse-aperture system
Results in Physics, 2020 Optical sparse-aperture (OSA) can greatly improve the spatial resolution of optical system. However, its optical designs are complex. This paper proposes a binaural sparse-aperture system with a simple and symmetrical structure, which is composed of ...

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Noise-Power Estimation Based on Ratio of Stationary Noise to Input Signal for Noise Reduction
, 2014 This paper proposes a method for estimating noise-power spectrum and reducing stationary noise components in noisy speech signal. Noise reduction generally suppresses the stationary noise by applying a multiplicative gain calculated from the estimated ...

Laser Diode based THz-TDS System with 133 dB peak Signal-to-Noise Ratio
, 2023 Abstract Terahertz time-domain spectroscopy (THz-TDS) has emerged as a powerful and versatile tool in various scientific fields. These include – among others – imaging, material characterization, and layer thickness measurements. While THz-TDS has achieved significant success in research environments, the high cost and bulky nature of most ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.
