To understand the ecology of juvenile chum salmon during early marine life after their downstream migration, we developed a quantitative PCR-based environmental DNA (eDNA) method specific for chum salmon and investigated the spatiotemporal distribution of eDNA in Otsuchi Bay, Iwate, Japan.Indoor aquarium experiments demonstrated the following chara
A high-power ultraflat near-infrared supercontinuum (SC) is generated in a section of photonic crystal fiber (PCF) pumped by an amplified spontaneous emission (ASE) source instead of continuous-wave (CW) and pulsed lasers.A low-power ASE seed at 1 μm is amplified to be 90.9 W by two fiber amplifiers and then emitted from a 10-μm-core
Trust establishment is an important tool to improve cooperation and enhance security in wireless sensor networks.The core of trust establishment is trust TEA TREE PURE-CASTILE SOAP estimation.If a trust estimation method is not robust against attack and misbehavior, the trust values produced will be meaningless, and system performance will be degra
One new genus and three new species Imaging Drum of Lygistorrhinidae in early Eocene Cambay amber from India are described, which significantly increases our knowledge about this group in the Eocene.Lygistorrhina indica n.sp.is the oldest fossil known from this extant genus.Indorrhina sahnii n.gen.et sp.shows morphological similarities to each of t
