摘要: The concentrations, variations, distribution and anomaly of cobalt values in stream sediments from Papua New Guinea (PNG) were studied based on the results of the Papua New Guinea National-Scale Geochemical Baseline (PNG-NGB) project (2015–2018). The data were studied to understand the spatial distribution of cobalt and its prospecting potential in PNG. 1399 samples were collected covering approximately 128,000 km2 with sample density of approximately 1.1 site/100 km2.

摘要: Relation classification is an important semantic processing task in the field of natural language processing. The deep learning technology, which combines Convolutional Neural Network and Recurrent Neural Network with attention mechanism, has always been the mainstream and state-of-art method. The LSTM model based on recurrent neural network dynamically controls the weight by gating, which can better extract the context state information in time series and effectively solve the long-standing pro关键词: Relation classification;attention mechanism;BERT;LSTM

摘要: 抄録(#br)Dynamical behavior of carriers in graphene has attracted academic interests to investigate temporal evolutions of the massless Dirac Fermions and also technical needs to develop the next-generation optoelectronic devices. The comprehensive understanding has been conducted by direct observations of the electronic states by time- and angle-resolved photoemission spectroscopy (TARPES). TARPES measurements on the epitaxial quasi-crystalline bilayer graphene observed the transient voltage betw

摘要: To investigate whether polymorphism of MTHFR C677T or MTHFR A1298C is associated with recurrent implantation failure (RIF).;This is a systematic review and meta-analysis. Pubmed, EMBASE, and CNKI (China national Knowledge Infrastructure) were searched for case-control studies that evaluated the associations between MTHFR polymorphisms (MTHFR C677T and MTHFR A1298C) and RIF. The pooled odds ratios (ORs) with 95% confidence intervals (CIs) were reported to evaluate the strength of association.

摘要: A pilot-scale horizontal subsurface flow constructed wetland (HFCW) was established to investigate the feasibility of removing nutrients from natural water in Lake Xijiu, Jiangsu Province, China. The HFCW, planted with reeds (Phragmites communis) and irises (Iris tectorum Maxim), was operated for 227 days. The mean removal efficiency of NH4+-N was 36.7%, of total nitrogen (TN) 70.2%, of total phosphorus 75.3%, of permanganate index (CODMn) 35.8%, and of Chlorophyll a 70.0%.

摘要: PPy-Fe3O4/Kaolin was prepared with polypyrrole functionalized magnetic Kaolin by a simple, green, and low cost method to improve the agglomeration and low adsorption capacity of Kaolin. PPy-Fe3O4/Kaolin was employed to remove Hg2+ and the results were characterized by various methods. Relevant factors, including solution pH, dosage of adsorbent, concentration (C0), and temperature (T), were optimized by Response Surface Methodology (RSM) and Central Composite Designs (CCD).

摘要: Density‐dependent non‐monotonic species interactions are important in maintaining ecosystem stability and function, but empirical evidences are still rare. Rodents, as both seed dispersers and seed predators, have dual effects on plant regeneration and may result in non‐monotonic rodent‐plant interactions. According to the non‐monotonic models, the relative positive or negative effects of rodents on seedling establishment can be measured based on the positive or negative association of seedling 关键词: ecological non‐monotonicity;plant–animal interaction;relative mutualism or predation;rodent abundance per seed

摘要: Urban flooding now occurs frequently and low impact development (LID) has been widely implemented as an effective resilience strategy to improve storm water management. This study constructed the inundation curve to dynamically simulate the disaster, and established an inundation severity indicator (ISI) and cost-effectiveness indicator (CEI) to quantify the severity and cost effectiveness at each site. The study set 10 different density scenarios using a zonal approach. The results showed that 关键词: Inundation curve; Cost-benefit analysis; Stormwater management; Low impact development; Resilience

摘要: Background: Biological system complexity impedes the drug target identification by biological experiments. Thus drugs, rather than acting on target site only, can interact with the entire biological system. Study of this phenomenon, known as network pharmacology, provides grounds for biological target identification of new drugs or acts as a foundation for the discovery of new targets of present drugs. No publication is available on the interaction network of CAPE.

A general solution is assumed as a modified version of Fourier series supplemented with boundary-smoothing auxiliary terms. Effects of axial load and elastic foundation of the beam are taken into account in terms of potential energy in system Lagrangian.

摘要: Anammox bacteria tend to self-aggregate, and biofilm-based anammox processes are widely used as sustainable alternative methods for nitrogen removal from wastewater. However, the mechanism for the initial adhesion of anammox bacteria remains unclear. In this work, extracellular polymeric substances (EPS) were extracted separately from anammox granules and then characterized by multi-methods. The adhesion properties of anammox consortia to biotic and abiotic surfaces were examined separately befo关键词: Anammox; Biofilm; Extracellular polymeric substances (EPS); Nitrogen removal; Structure

摘要: Abstract:Degree distribution plays a great role in the performance of Luby transform codes. Typical degree distributions such as ideal soliton distribution and robust soliton distribution are easy to implement and widely used. Nevertheless, their adaptabilities are not always outstanding in various code lengths, especially in the case of short length. In this paper, our work is to optimize degree distributions for the short-length LT codes by using swarm intelligence algorithm, considering its c关键词: Fountain codes;LT code;Degree distribution;Differential evolution;Chicken swarm optimization

摘要: People often need to make intertemporal choices in their daily life, such as savings and spending, but their decisions are not always entirely rational. The purpose of this paper is to study the effect of hunger on intertemporal choices and the moderating effect of sensitivity to reward.,Two studies verified these two hypotheses. The first study confirmed the existence of the main effect by manipulating food aroma. In the second study, by manipulating hunger with images, the authors increased ex关键词: Discounts;Hunger;Intertemporal choices;Saving and spending;Sensitivity to reward

摘要: Owing to their nutritional and commercial values, the genomes of several citrus plants have been sequenced, and the genome of one close relative in the Rutaceae family, atalantia (Atalantia buxifolia), has also been sequenced. Here, we show a family-level comparative analysis of Rutaceae genomes. By using grape as the outgroup and checking cross-genome gene collinearity, we systematically performed a hierarchical and event-related alignment of Rutaceae genomes, and produced a gene list defining 关键词: Rutaceae; Whole-genome duplication; Genome alignment; Gene collinearity; Duplicated genes; Genome fractionation

摘要: Habitat loss and fragmentation often leads to defaunation of large‐bodied mammals, and their loss could trigger release from top‐down control or food resource competition for small mammal seed dispersers, which in turn may affect the effectiveness of seed dispersal by altering the number of dispersed seeds or the manner in which they are dispersed. Although rodents are primary seed dispersers in habitat subjected to defaunation, changes in seed dispersal effectiveness of rodents along mammalian 关键词: Defaunation; Forested area; Indirect effects; Isolation; Scatter‐hoarding rodent–oak interaction; Seed dispersal effectiveness; Thousand Island Lake
