Antarctic krill (Euphausia superba) is Earth’s most abundant wild animal, and its enormous biomass vital to the Southern Ocean ecosystem. Here, we report a 48.01-Gb chromosome-level genome, whose large genome size appears have resulted from inter-genic transposable element expansions. Our assembly reveals molecular architecture of circadian clock uncovers expanded gene families associated with molting energy metabolism, providing insights into adaptations cold highly seasonal environment....
The Community Atmosphere Model (CAM) is ported, redesigned, and scaled to the full system of Sunway TaihuLight, provides peta-scale climate modeling performance. We refactored optimized complete code using OpenACC directives at first stage. A more aggressive finer-grained redesign then applied on CAM, achieve finer memory control usage, efficient vectorization compute communication overlapping. further improve CAM performance a 260-core processor range 28 184 Intel CPU cores, sustainable...
This paper reports our efforts on refactoring and optimizing the Community Atmosphere Model (CAM) Sunway TaihuLight supercomputer, which uses a many-core processor that consists of management processing elements (MPEs) clusters computing (CPEs). To map large code base CAM to millions cores system, we take OpenACC-based as major approach, apply source-to-source translator tools exploit most suitable parallelism for CPE cluster, fit intermediate variable into limited on-chip fast buffer. For...
Krill and salps are important for carbon flux in the Southern Ocean, but extent of their contribution consequences shifts dominance from krill to remain unclear. We present a direct comparison salp faecal pellets (FP) vertical at Antarctic Peninsula using combination sediment traps, FP production, content, microbial degradation, abundances. Salps produce 4-fold more than krill, both species contribute equally 300 m, accounting 75% total carbon. exported 72% while 80% retained mixed layer due...
Abstract Antarctic krill Euphausia superba , one of the most abundant species on planet, is a keystone Southern Ocean ecosystem. In present study, we analyzed RNA virome via metatranscription methods. The results showed that only 0.39% (49/12, 558) resultant unigenes could be assigned to known viral taxa, which were similar 17 viruses, including nine invertebrate two vertebrate three protozoan viruses and mycoviruses. However, detected possessed low amino acid similarity with counterparts in...
In this work an ultra-scalable algorithm is designed and optimized to accelerate a 3D compressible Euler atmospheric model on the CPU-MIC hybrid system of Tianhe-2. We first reformulate mesocale avoid long-latency operations, then employ carefully inter-node intra-node domain decomposition algorithms achieve balance utilization different computing units. Proper communication-computation overlap concurrent data transfer methods are utilized reduce cost movement at scale. A variety...
This paper presents a hybrid algorithm for the petascale global simulation of atmospheric dynamics on Tianhe-2, world's current top-ranked supercomputer developed by China's National University Defense Technology (NUDT). Tianhe-2 is equipped with both Intel Xeon CPUs and Phi accelerators. A key idea to enable flexible domain partition between an arbitrary number processors accelerators, so as achieve balanced efficient utilization entire system. We also present asynchronous concurrent data...
An interlayer favoring Li ion diffusion and polysulfide blocking for Li–S batteries was fabricated by using porous carbon nanosheets embedded with TiO<sub>2</sub> nanoparticles.
Organic fertilization, a critical agronomic practice for improving nutrient availability and crop growth, may increase the risk of phosphorus (P) loss. To investigate effect organic fertilization on P availability, growth loss, paddy field experiment was conducted in saline-alkaline soil. We designed four treatments: CK (no fertilizer), NPK (mineral NPKC1 NPKC2 fertilizer with low high levels fertilizer, respectively); amounts N, P2O5, K2O were equal NPK, NPKC1, treatments. Compared...
Abstract Antarctic krill is a key species in the Southern Ocean and subject to most extensive fishery Antarctic. The Norwegian Institute of Marine Research has conducted acoustic-trawl monitoring off South Orkneys annually since 2011 collaboration with fishing industry. Average biomass within 60000 km2 survey area ranged from 1.4 7.8 million tonnes period 2011–2020, strongly supporting that this among regions Scotia Sea consistently highest densities. There were no significant (p ≈ 0.18,...
Cadmium (Cd) exposure is a widespread problem in many parts of the world, but effective means to treat Cd still lacking. Hence, an engineered strain expressing metallothionein (MT) named Escherichia coli Nissle 1917 (EcN)-MT was constructed, and its potential treatment evaluated. The vitro studies showed that expressed by EcN-MT could significantly bind Cd. Further, vivo results indicated reduce 26.3% liver increase 24.7% feces, which greatly decreased malondialdehyde (MDA) levels increased...
Stencil computation arises from a broad set of scientific and engineering applications often plays critical role in the performance extreme-scale simulations. Due to memory bound nature, it is challenging task opti- mize stencil kernels on modern supercomputers with relatively high computing throughput whilst low data-moving capability. This work serves as demon- stration details algorithms, implementations optimizations real-world 3D nonhydrostatic atmospheric modeling newly announced...

The Western Subarctic Gyre (WSG) is a cyclonic upwelling gyre in the northwest subarctic Pacific, which region with high concentration of nutrients but low chlorophyll. We investigated community structure and spatial distribution phytoplankton this area by using HPLC-pigment CHEMTAX (a chemotaxonomy program) metabarcoding sequencing during summer 2021. showed significant differences between two methods. analyses identified eight major marine assemblages. Cryptophytes were contributors...
Stencils are among the most important and time-consuming kernels in many applications. While stencil optimization has been a well-studied topic on CPU platforms, achieving higher performance efficiency for evolving numerical stencils more recent multi-core many-core architectures is still an issue. In this paper, we explore number of different stencils, ranging from basic 7-point Jacobi to complex high-order used finer simulations. By optimizing analyzing those latest (the Intel Sandy Bridge...
Phosphorus (P) is an essential nutrient element of phytoplankton, as well a limiting factor for phytoplankton growth. It controls the succession blooms from diatoms to dinoflagellates, especially in East China Sea (ECS), where eutrophication serious. Most studies have only considered single aspect dissolved inorganic phosphorus (DIP) or organic (DOP). In contrast, we investigated growth interactions among major bloom-forming marine diatom Skeletonema costatum and dinoflagellates Prorocentrum...
