The estimation of spectroscopic and photometric redshifts (spec-z and photo-z) is crucial for the future cosmological surveys. It can directly affect several powerful measurements of the Universe, e.g. weak lensing and galaxy clustering. In this work, we explore the accuracies of spec-z and photo-z that can be obtained in the China Space Station Optical Surveys (CSS-OS), which is a next-generation space survey, using neural network. The 1-dimensional Convolutional Neural Networks (1-d CNN) and Multi-Layer Perceptron (MLP, a simplest form of Artificial Neural Network) are employed to derive the spec-z and photo-z, respectively. The mock spectral and photometric data used for training and testing the networks are generated based on the COSMOS catalog. The networks have been trained with noisy data by creating Gaussian random realizations to reduce the statistical effects, resulting in similar redshift accuracy for both high-SNR (signal to noise ratio) and low-SNR data. The probability distribution functions (PDFs) of the predicted redshifts are also derived via Gaussian random realizations of the testing data, and then the best-fit redshifts and 1-σ errors also can be obtained. We find that our networks can provide excellent redshift estimates with accuracies ∼0.001 and 0.01 on spec-z and photo-z, respectively. Compared to existing photo-z codes, our MLP has similar accuracy but is more efficient in the training process. The fractions of catastrophic redshifts or outliers can be dramatically suppressed comparing to the ordinary template-fitting method. This indicates that the neural network method is feasible and powerful for spec-z and photo-z estimations in the future cosmological surveys. Copyright © 2021, The Authors. All rights reserved.

This study uses archival high frequency continuum data to expand the search for Hypercompact HII regions and determine the conditions at which they appear, as this stage high mass star formation is short-lived and rare. We use 23 GHz continuum data taken towards methanol masers, which are an excellent signpost for very young embedded high-mass protostars. We have searched for high-frequency, optically thick radio sources to identify HC HII region candidates. The data cover 128 fields that include 141 methanol masers identified by the Methanol Multibeam (MMB) survey. We have detected 68 high-frequency radio sources and conducted a multi-wavelength analysis to determine their nature. This has identified 49 HII regions, 47 of which are embedded in dense clumps fourteen of which do not have a 5 GHz radio counterpart. We have identified 13 methanol maser sites that are coincident with radio sources that have a steep positive spectral index. The majority of these are not detected in the mid-infrared and have been classified as protostellar or young stellar objects in the literature and we therefore consider to be good HC HII region candidates, however, further work and higher resolution data are needed to confirm these candidates. © 2023, CC BY.

Sustainable peroxymonosulfate activation by 1T/2H-MoS 2 cathode for enhanced removal of organic pollutants: Performance and nonradical activation mechanism based on surface Mo-peroxymonosulfate complexes

MoS 2 is an effective catalyst for peroxymonosulfate (PMS) activation, but its poor reusability hinders the practical application. To address this issue, we immobilized multiphasic 1T/2H-MoS 2 onto a carbon fiber cloth (1T/2H-MoS 2 @CFC) and utilized it as the cathode to sustainably activate PMS because electrons supplied by cathode can regenerate Mo catalytic sites. In addition, the electrochemical 1T/2H-MoS 2 @CFC cathode/PMS system manifests enhanced removal performance of aqueous organic pollutants by coupling PMS activation with electrosorption of organics. Through integrated experimental and theoretical investigations, we found that negative polarization of 1T/2H-MoS 2 makes the electrostatic potential of Mo active sites in 1T/2H-MoS 2 more positive and l S-O of adsorbed HSO 5 − longer, while positive polarization does the opposite. Accordingly, 1T/2H-MoS 2 cathode attains higher PMS activation efficiency than the anode and induces formation of nonradical surface Mo-PMS complexes, differing from the activation pathway induced by 1T/2H-MoS 2 anode which involves •OH, SO 4 •- and 1 O 2 . Finally, the degradation performance of 1T/2H-MoS 2 @CFC cathode/PMS system in different real water matrices was assessed and it was found to perform effectively in all cases. Our findings offer an efficient and economical electrochemical oxidative system for water decontamination.

Seldom could metals and alloys maintain excellent properties in cryogenic condition, such as the ductility, owing to the restrained dislocation ***, a face-centered-cubic(FCC) CoCrFeNi highentropy alloy(HEA) with great ductility is investigated under the cryogenic environment. The tensile strength of this alloy can reach a maximum at 1,251±10 MPa, and the strain to failure can stay at as large as 62% at the liquid helium temperature. We ascribe the high strength and ductility to the low stacking fault energy at extremely low temperatures,which facilitates the activation of deformation ***, the FCC→HCP(hexagonal close-packed) transition and serration lead to the sudden decline of ductility below 77 K. The dynamical modeling and analysis of serrations at 4.2 and 20 K verify the unstable state due to the FCC→HCP transition. The deformation twinning together with phase transformation at liquid helium temperature produces an adequate strain-hardening rate that sustains the stable plastic flow at high stresses, resulting in the serration feature.

In recent decades, ships' ballast water and associated sediments have been recognized globally as significant vectors for the dissemination of non-indigenous species, which has attracted extensive attention due to its ecological and economic impacts. The characteristics of production of resting cysts in the dinoflagellate life cycle further increases the risk of biological invasions through ballast tank sediments. Despite extensive research which has characterized the species diversity of dinoflagellate cysts within ballast tank sediments, the possibility and importance of invasions caused by different ribosomal types of the same species have been paid little attention. In this study, two cultures of dinoflagellates were established through cyst germination from the ballast tank sediments collected from two ships ("THETIS" and "WARIYANAREE") arriving at the Jiangyin Port (China) and identified as Wangodinium sinense Z. Luo, Zhangxi Hu, Yingzhong Tang and H.F. Gu by comprehensive phylogenetic analysis of rDNA sequences (including LSU, SSU, and ITS1-5.8S-ITS2). Despite the rDNA sequences of the isolates showing a generally high similarity to reference sequences, the LSU D1-D6 sequences contained up to 11 stable single nucleotide polymorphisms (SNPs), while SSU and ITS1-5.8S-ITS2 sequences exhibited up to five and two divergence sites, respectively. Moreover, phylogenetic analyses based on partial LSU and SSU rDNA sequences further indicated that strains germinated from ships' ballast tank sediments formed a strongly supported sister clade to the strains previously isolated from Chinese and Korean waters, representing a novel ribo-type distinct from Chinese and Korean strains. Detailed morphological observations using light microscopy (LM) and scanning electron microscopy (SEM) did not find differences between our isolates and the holotype of the species in key diagnostic characteristics including the position and shape of the nucleus and chloroplasts, as well as the A

Ground anchor drilling is a promising technology for investigating the mechanical properties and environmental variability of lunar regolith in low-gravity environments, with minimal demands for reactive cutting. This study explores the interaction behavior during ground anchor drilling of lunar regolith by employing a coupled approach that integrates the Material Point Method (MPM) and the Continuous–Discontinuous Element Method (CDEM), considering the interactions among numerous particles and blocks. The numerical parameters are calibrated based on experimental penetration resistance data of lunar regolith simulant. The numerical approach effectively captures key mechanical properties of the simulant, such as particle flow and scattering patterns, anchor penetration effects, and disturbance-related ultimate bearing characteristics. Additionally, this study examines the influence of inter-particle friction and compactness on penetration resistance. By combining the Golden Section Search Method (GSSM) with ground anchor drilling simulations, an inverse analysis model for penetration resistance is developed, allowing for the determination of mechanical parameters of the lunar regolith simulant. The feasibility of this parameter inversion method is verified, providing valuable insights for engineering applications in lunar exploration and construction.

Very metal-poor (VMP) stars record the signatures of early accreted galaxies, making them essential tools for unraveling the early stages of Galaxy formation. Understanding the origin of VMP stars requires comprehensive studies of their chemical compositions and kinematics, which are currently lacking. Hence, we conduct a chemodynamical analysis of 352 VMP stars selected from one of the largest uniform high-resolution VMP star samples, jointly obtained from LAMOST and Subaru. We apply a friends-of-friends clustering algorithm to the master catalog of this high-resolution sample, which consists of 5778 VMP stars. It results in 131 dynamically tagged groups with 89 associated with known substructures in the Milky Way, including Gaia-Sausage-Enceladus (GSE), Thamnos, Helmi streams, Sequoia, Wukong, Pontus, and the very metal-poor disk (VMPD). Our findings are: (i) the VMPD shows lower Zn abundances than the rest, which indicates that it could be a relic of small stellar systems;(ii) Sequoia shows moderately high r-process abundances;(iii) Helmi streams show deficiencies in carbon and light neutron-capture elements;(iv) the fraction of carbon-enhanced metal-poor stars with no enhancement in heavy elements (CEMP-no stars) seems low in the VMPD and the Helmi streams;and (v) a subgroup in GSE exhibits a very high fraction of r-process enhanced stars, with four out of five showing [Eu/Fe]> +1.0. The abundance patterns of other elements in VMP substructures largely match the whole VMP sample. We also study large-scale correlations between abundance ratios and kinematics without classifying stars into substructures, but it does not yield significant correlations once the overall chemical evolution is considered for most elements. © 2024, CC BY.
