We consider a compression problem in a multi-source status-updating system through a representative two-source scenario. The status updates are generated by two independent sources following heterogeneous Poisson processes. These updates are then compressed into binary strings and sent to the receiv...

This paper presents the research studies carried out on the application of lattice Boltzmann method (LBM) to computational aeroacoustics (CAA). The Navier-Stokes equation-based solver faces the difficulty of computational efficiency when it has to satisfy the high-order of accuracy and spectral reso...

Recent investigations have identified two-dimensional black phosphorene (BP), a semiconductor material, as a promising candidate for thermoelectric applications. However, its thermoelectric performance requires further enhancement. Through first-principle calculations combined with semi-classical Bo...

The viability of the star count (Wolf) method is assessed as a means of constraining the near-infrared (NIR) extinction law toward the Corona Australis molecular cloud. Using deep JHK _S photometry from the VISIONS survey, extinction maps with 1′ spatial resolution are constructed. The derived extin...

Chitinases play an important role in biological decomposition of chitin. A large number of chitinases have been isolated from microorganisms. Although every member of the enzymes is different from each other, they have some common structures, such as signal peptides, catalytic domains and chitin-bin...

ABSTRACT Background Hearing loss, characterized by significant genetic heterogeneity, is a widespread global disorder. Mutations in the OTOG and OTOGL genes have recently been implicated in non‐syndromic sensorineural hearing loss. However, the mutation spectrum of OTOGL and its functional relevance...
