title: Scale dependent niche conservatism found in fish communities of the largest freshwater lake in China
title: Scale dependent niche conservatism found in fish communities of the largest freshwater lake in China

description: Investigations to niche evolution lead to controversial results in ecological studies: the competitive exclusion principle (CEP) predicts that closely-related species should be sufficiently divergent to coexist, whereas niche conservatism (NC) suggests that closely-related species should be more ecologically similar. Here, we employ stable isotope ratios (δ13C, δ15N) to estimate trophic niches and test niche evolution in fish communities of Poyang Lake, central China. At a broad scale involving 57 species, by examining the relationship between trophic niche differences along genetic distances and testing phylogenetic signals, we found trophic differences were positively associated with genetic distances, showing strong phylogenetic signals. We then focused on 7 Cultrinae species at local scale comparing trophic niche differences within and between sister species, closely-related species, and distantly-related species, and found that trophic differences between distantly-related species were significantly larger than those between closely-related species, supporting NC. However, trophic differences between sister species were larger than those between closely-related species, suggesting the importance of CEP but not NC. Therefore, our findings suggest that niche evolution operates in a scale-dependent manner: at a broad spatial and deep phylogenetic scale, NC may be present, whereas at a small local scale, CEP may be more applicable.

title: Modeling solar corona with implicit high-order reconstructed discontinuous Galerkin scheme
title: Modeling solar corona with implicit high-order reconstructed discontinuous Galerkin scheme

description: The present study aims to apply an implicit high-order reconstructed discontinuous Galerkin scheme (rDG(P1P2)) to simulate the steady-state solar corona. In this scheme, a piecewise quadratic polynomial solution, P2, is obtained from the underlying piecewise linear DG solution, P1, by the least-squares reconstruction with weighted essentially non-oscillatory (WENO) limiter. The reconstructed quadratic polynomial solution is then used for the computation of the fluxes and source terms. In addition, implicit time integration method with large time steps is considered in this work. The resulting large linear algebraic system of equations from the implicit discretization is solved by the cellwise relaxation implicit scheme which can make full use of the compactness of DG scheme. The code of the implicit high-order rDG scheme is developed in Fortran language with message passing interface parallelization in Cartesian coordinates. To validate this code, we first test a problem with exact solution, which confirms the expected third-order accuracy. Then we simulate the solar corona, and compare the modeled results with the observations. We find that there is an overall agreement between the simulated results and the observations, which demonstrates the capability of the developed scheme.

title: A General Simulation System for Housekeeping Platform and Payload Function Interfaces

description: The Housekeeping Platform and Payload Function Interfaces Simulation System (HPPFISS) is a crucial development assurance system utilized in the development of satellite platforms. Its primary function is to test the functionality and performance of On-board Data Handling (OBDH) products to ensure their correctness and robustness. However, different satellite platforms have varying interface simulation system requirements, necessitating the development or redevelopment of interface simulation systems for each task. To address this issue, a universal HPPFISS with strong versatility is proposed in this article. The system can be directly applied to various development tasks through simple configuration operations, reducing the investment in simulation systems and accelerating development progress. The HPPFISS is based on the concept of reconfigurable design, ensuring its generality at the program, hardware, and FPGA levels. Testing has been conducted to verify the feasibility and universality of the system proposed in this article.

title: A demo dataset of genotype and phenotype for ALGWAS

description: The genotypic file requires a header row, which shows the names of individuals. The first row shows the names of molecular markers or SNPs. For each SNP, the genotypes, e.g., AA, AT, TT, are required to transformed to integer format as 0, 1 or 2 based on allelic frequency. For example, A is the major allele that AA and TT will be transformed to 0 and 2, the AT is transformed to 1. It means the copy number of minor alleles for a line at a SNP locus, relative to major allele. The phenotype file must contain a header row, which represents the names of traits. The first column shows the names of the individuals (Table 2). The trait values are numeric and missing values are indicated as NA, following the R coding requirement.

title: “明安图射电频谱日像仪图像的强度定标方法”论文的图像

description: The files are figures for manuscript "Intensity Calibration Method for the Mingantu Spectral Radioheliograph Images". The radio brightness temperature is an important parameter to describe the solar physical process. It plays a very important role in the study of different radio radiation mechanisms, solar magnetic field and the acceleration of non-thermal electrons in the solar burst process. Therefore the image of radioheliograph must be calibrated for brightness temperature. This paper will introduce a method suitable for radioheliograph image calibration. The solar radio image contains the structure information of the solar disk. The radio radius and intensity of the quiet solar disk in the image can be obtained by fitting the first kind of Bessel function with the visibilities of short baselines of the radioheliograph. Then the calibration factor Gc of the image can be calculated by using Rayleigh-Kings law and solar radio flux, so as to realize the calibration of the MUSER image.
