A Compact Low-Loss Broadband Polarization Independent Silicon 50/50 Splitter
IEEE Photonics Journal, 2021 We present a low-loss, compact, polarization insensitive 3-dB optical power-splitter for submicron silicon waveguides. The splitter is optimized over a broad wavelength span ranging from 1300 to 1700 nm through finite difference time domain simulations ...

Boundary‐independent polar nonsense‐mediated decay [PDF]
EMBO reports, 2002 Nonsense‐mediated decay (NMD) is an RNA surveillance mechanism that degrades mRNAs containing premature termination (nonsense) codons. The second signal for this pathway in mammalian cells is an intron that must be at least ∼55 nucleotides downstream of the nonsense codon.
