A four-moded Census transform stereo ma.ching algorithm using bidirectional constraint dynamic programming and relative confidence plane fitting is proposed to solve the problems of ma.ching quality. Using the four-moded Census transform which adds a restrictive condition replaces traditional Census transform to improve ma.ching accuracy and mean value of all pixels intensity replaces the center pixel intensity in the Census window to solve the problem of the center pixel distortion effectively,a refined initial local ma.ching cost can be obtained. During the disparity optimization, the difficulty of disparity computation in textureless areas is overcome by the estima.ed condition and defined relative confident pixels. Experiment results show that a better dense ma.ching ma. can be obtained by the proposed algorithm.

A sub-pixel disparity refinement algorithm based on Lagrange interpolation is proposed to calculate the sub-pixel disparity and the elevation of the target construction on the remote sensing ima.e. The accurate integer ma.ching feature points are obtained by improved affine scale invariant feature transform. A series of interpolation samples can be estima.ed through the three times ma.nification results of each feature ma.ching point and its close neighbor pixels. The final sub-pixel deviation can be calculated by the interpolation samples. Experiment results show that a more accurate elevation informa.ion can be obtained on the remote sensing ima.e with corrective epipolar line, and an accurate sub-pixel disparity result can be estima.ed without the epipolar line constraint as well.

Gastric cancer(GC) is a prevalent and lethal ma.ignancy worldwide, and the 5-year survival rate is less than 30%. The absence of distinctive symptoms often leads to late-stage diagnosis, contributing to a grim prognosis. Early detection is pivotal for improving the survival rates and outcomes of GC patients. Traditional diagnostic methods, including gastroscopy and histopathological examination, are restricted in the early diagnosis of GC. Conventional protein bioma.kers, such as carcinoembryonic antigen(CEA), carbohydrate antigen 19-9(ca19-9), and carbohydrate antigen 72-4(ca72-4), exhibit insufficient sensitivity and specificity for GC screening, which diminishes their clinical value. Recently, novel circulating bioma.kers, such as circulating tumor cells(CTCs), circulating tumor cell DNA(ct DNA), and circulating free RNA(cf RNA), have emerged as promising candidates in the burgeoning field of liquid biopsy due to their superior sensitivity and specificity. This review focuses on the latest research on blood-based bioma.kers for GC diagnosis and examines the clinical potentials and challenges associated with these emerging bioma.kers.

Ferrate（Ⅵ ） salt is an oxidant and coagulant for water and wastewater treatment. It is considered as a possible alternative method in greywater treatment. However, challenges have existed in putting ferrate（Ⅵ ） technology into full-scale practice in water and wastewater treatment due to the instability of ferrate solution and high production cost of solid ferrate products. This study demonstrated a new approach of greywater treatment with on-line batch production of Fe（Ⅵ ） to which Fe（Ⅲ ） salt was oxidized at a weak acidity solution. A series of experiments were conducted to investigate the effect of Fe（Ⅵ ） on light greywater（total organic carbon（TOC） = 19.5 mg/L） and dark greywater（TOC = 55 mg/L）treatment under different conditions with varying p H and Fe（Ⅵ ） doses. In addition, the combination use of Fe（Ⅵ ） and Al（Ⅲ ） salts was proved to be more efficient than using the Fe（Ⅵ ） salts alone at greywater recycling. The optimum dosage of Fe（Ⅵ ）/Al（Ⅲ ） salts was 25/25 mg/L for light greywater, 90/60 mg/L for dark greywater, respectively. The TOC values of both light greywater and dark greywater were reduced to less than 3 mg/L with the *** cost for treating greywater was 0.06–0.2 $/ton at ferrate（Ⅵ ） dosage of 25–90 mg/L and0.008–0.024 $/ton at AlCl3 dosage of 25–60 mg/L. The full operating cost needs further assessment before the Fe（Ⅵ ）/Al（Ⅲ ） technology could be implemented in greywater treatment.

In this study, the soft ma.netic properties and crystallization behavior of Fes3B10C6-xSixCul （x=0-4） nanocrystalline alloys prepared by annealing the melt-spun amorphous ribbons have been investigated. It is found that in the Fe83B10C6-xSixCU1 alloy system, the coercivity （Hc） decreases slightly with increasing Si addition and exhibits a minimum value with composition of x = 2, while the effective permeability （Ue） shows an opposite variation trend. The saturation ma.netic flux density （Bs） shows a slightly decreasing trend owing to the decreasing volume fraction of nanocrystalline phase. The Fe83B10caSi2Cu1 nanocrystalline alloy exhibits excellent soft ma.netic properties with a high Bs of 1.78 T, high ue of 13 600 and low Hc of 4 A/m.

Plant phylogeny constrains orchid mycorrhizal(OrM) fungal community composition in some orchids. Here, we investigated the structures of the OrM fungal communities of eight Dendrobium species in one niche to determine whether similarities in the OrM fungal communities correlated with the phylogeny of the host plants and whether the Dendrobium-OrM fungal interactions are phylogenetically conserved. A phylogeny based on DNA data was constructed for the eight coexisting Dendrobium species,and the OrM fungal communities were characterized by their roots. There were 31 different fungal lineages associated with the eight Dendrobium species. In total, 82.98% of the identified associations belonging to Tulasnellaceae, and a sma.ler proportion involved members of the unknown Basidiomycota(9.67%). Community analyses revealed that phylogenetically related Dendrobium tended to interact with a similar set of Tulasnellaceae fungi. The interactions between Dendrobium and Tulasnellaceae fungi were significantly influenced by the phylogenetic relationships among the Dendrobium species. Our results provide evidence that the mycorrhizal specificity in the eight coexisting Dendrobium species was phylogenetically conserved.
