Abstract Reconstructing the genomes of bilaterian ancestors is central to our understanding animal evolution, where knowledge from ancient and/or slow-evolving lineages critical. Here we report a high-quality, chromosome-anchored reference genome for scallop Patinopecten yessoensis , bivalve mollusc that has with many ancestral features. Chromosome-based macrosynteny analysis reveals striking correspondence between 19 chromosomes and 17 presumed linkage groups at level conservation...
Bivalve molluscs are descendants of an early-Cambrian lineage superbly adapted to benthic filter feeding. Adaptations in form and behavior well recognized, but the underlying molecular mechanisms largely unknown. Here, we investigate genome, various transcriptomes, proteomes scallop Chlamys farreri, a semi-sessile bivalve with well-developed adductor muscle, sophisticated eyes, remarkable neurotoxin resistance. The scallop's large striated muscle is energy-dynamic not fully differentiated...
Echinoderms exhibit several fascinating evolutionary innovations that are rarely seen in the animal kingdom, but how these animals attained such features is not well understood. Here we report sequencing and analysis of genome extensive transcriptomes sea cucumber
Simultaneous measurement of pressure and temperature in seawater is realized based on polydimethylsiloxane (PDMS) sealed microfiber Mach-Zehnder interferometer (MZI). Benefitting from the high thermal-optic coefficient large elasticity PDMS, sensitivity robust structure can be obtained. In theoretical modeling, significant enhanced response fiber observed clearly, or sensitivities are calculated theoretically. experiment, PDMS MZI fabricated by a two-step sealing method. Using this MZI,...
It is significant to develop new methods for temperature and salinity measurement in seawater since they are two important parameters physical oceanography application. In this paper, a approach simultaneous of based on microfiber Mach-Zehnder (MZ) interferometer with knot resonator proposed. The typical transmission spectra show the combined effect MZ interference resonance. When change, both dip resonance shift linearly. Based linear relation, matrix established, sample can be obtained...
The salinity and temperature of seawater are important parameters in oceanography. Based on the directional coupler assembled by polyimide-coated micro/nanofibers, optical sensors with high sensitivity for simultaneous sensing proposed. Dependences sensitivities wavelength, salinity, investigated theoretically, which performances such sensor under general sea conditions can be evaluated. Results show that reach levels nm/‰ nm/°C, much higher than those fiber Bragg gratings, knot resonators,...
A simple, high-sensitivity, and low-cost optical sensor for the measurement of temperature salinity in seawater is demonstrated based on a microfiber directional coupler. The shifts sensing dips are highly sensitive to change with highest sensitivities at 930 pm/% -160 pm/°C coupler assembled by 3.79and 2.20-μm-diameter fibers. sensitivity can be further improved -1130 smaller fibers diameters 3.50 1.35 μm. To keep stable structure liquid, methodology coating using ethyl cellulose ethoce...
Gaofen-3 (GF-3), the first Chinese civil C-band synthetic aperture radar (SAR), was successfully launched by China Academy of Space Technology on 10 August 2016. Among its 12 imaging modes, wave mode is designed to monitor ocean surface waves over open ocean. An empirical retrieval algorithm significant height (SWH), termed Quad-Polarized WAVE for GF-3 (QPCWAVE_GF3), developed quad-polarized SAR measurements from in mode. QPCWAVE_GF3 model built using six image and spectrum related...
Combined with non-adiabatic tapering and mode field mismatch between two different fibers, a splicing point tapered fiber Mach-Zehnder interferometer is proposed. Theoretically, sensing units are carefully designed for dual-parameter sensing, exciting evolution in fibers analyzed shown dynamically. In experiment, transmission spectrum obtained sets of clear interference as designed. After simple capsulation, simultaneous measurement seawater temperature salinity realized sensitivities...
In this paper, an ultrahigh sensitivity sensing in aqueous solution for microfiber modal interferometer (MMI) is realized. The group refractive index (RI) difference between HE11 and HE12 mode will come down to 0 at a certain wavelength, resulting near wavelength. MMI with different diameters have their individual ultrasensitive wavelength band, which indicates the broad range of optional probing more liberal diameter condition on fiber fabrication. experimentation, infrared absorption band...
Despite the extensive use of distributed fiber optic sensing (DFOS) in monitoring underground structures, its potential detecting structural anomalies, such as cracks and cavities, is still not fully understood. To contribute to identification defects this study conducted a four-point bending test reinforced concrete (RC) beam uniaxial loading tests an RC specimen with local cavities. The experimental results revealed disparity DFOS strain spike profiles between these two anomalies....
