ABSTRACT We use weak lensing observations to make the first measurement of characteristic depletion radius, one three radii that characterize region where matter is being depleted by growing haloes. The lenses are taken from halo catalogue produced extended halo-based group/cluster finder applied DESI Legacy Imaging Surveys DR9, while sources extracted DECaLS DR8 imaging data with fourier_quad pipeline. study masses $12 \lt \log (M_{\rm grp} \,[{\rm M_{\odot }}\, h^{-1}]) \le 15.3$ within...
Based on a large group/cluster catalog recently constructed from the DESI Legacy Imaging Surveys DR9 using an extended halo-based group finder, we measure and model group-galaxy weak lensing signals for groups/clusters in few redshift bins within range $0.1 \leqslant z<0.6$. Here, background shear are obtained based DECaLS survey shape derived with \textsc{Fourier\_Quad} method. We divide lens samples into 5 equispaced 7 mass bins, which allow us to probe dependence of hence resulting halo...
In this paper, we set out to construct a of reference mock galaxy redshift surveys (MGRSs) for the future Chinese Space-station Survey Telescope (CSST) observation, where subsequent survey selection effects can be added and evaluated. This MGRSs is generated using dark matter subhalos extracted from high-resolution Jiutian $N$-body simulation standard $\Lambda$CDM cosmogony with $\Omega_m=0.3111$, $\Omega_{\Lambda}=0.6889$, $\sigma_8=0.8102$. The has boxsize $1~h^{-1} {\rm Gpc}$, consists...
An improved complex network approach named weighted ego analysis (WENA) was employed to explore the hierarchical structure of global shipping network. First, it found that all centrality indices exhibited scale-free properties with obvious power-law distributions. That is, less than 30% ports had quite high values, which are powerful hubs system. Those very accessible showed significant preferential attachment such as 'rich-club' and 'Matthew' effect. Second, results WENA revealed its...

Background: Super-resolution (SR) refers to the use of hardware or software methods enhance resolution low-resolution (LR) images and produce high-resolution (HR) images. SR is applied frequently across a variety medical imaging contexts, particularly in enhancement neuroimaging, with specific techniques including microscopy—used for diagnostic biomarkers—and functional magnetic resonance (fMRI)—a neuroimaging method measurement mapping brain activity. This bibliometric analysis literature...
ABSTRACT Cluster cosmology depends critically on how optical clusters are selected from imaging surveys. We compare the conditional luminosity function (CLF) and weak-lensing (WL) halo masses between two different cluster samples at fixed richness, detected within same volume (0.1 &lt; z 0.34) using red-sequence halo-based methods. After calibrating our CLF deprojection method against mock galaxy samples, we measure 3D CLFs by cross-correlating with Sloan Digital Sky Survey photometric...
Effects of out-of-plane shear flows on fast magnetic reconnection in Hall magnetohydrodynamics approximation are studied a slab model with an initial Harris sheet equilibrium. It is found that the can also generate series perturbations significantly modify quadrupolar perturbation induced by effect reconnection. The modification to then considerably affects process. Particularly, along X-line either enhance or reduce rate, even altering X-point O-point and resulting secondary island. impact...

To support our analysis, utilize a realistic DESI Mock Galaxy Redshift (MGRS) generated from high-resolution Jiutian simulation. An extended halo-based group finder is applied...
Abstract A reliable technique is introduced to detect aerodynamic instability of compressors based on wavelet features and hidden Markov model (HMM). single sensor sufficient for stall warning if the position carefully selected.

Dynamic mode decomposition (DMD) is widely used in extracting the main features of high-dimensional nonlinear systems computational fluid dynamics. However, it cannot be directly applied to real compressors due limitations data acquisition over entire flow field. In order overcome this limitation, our paper proposes a time-delay-locked DMD algorithm. It combines idea phase locking, Hankel time-delay method, and method. Based on it, patterns are successfully extracted unsteady phenomena...
