The similarity measure is crucial to the performance of spectral clustering. The Gaussian kernel function based on the Euclidean distance is usual y adopted as the similarity measure. However, the Euclidean distance measure cannot ful y reveal the complex distribution data, and the result of spectral clustering is very sensitive to the scaling parameter. To solve these problems, a new manifold distance measure and a novel simulated anneal-ing spectral clustering （SASC） algorithm based on the manifold distance measure are proposed. The simulated annealing based on genetic algorithm （SAGA）, characterized by its rapid convergence to the global optimum, is used to cluster the sample points in the spectral mapping space. The proposed algorithm can not only reflect local and global consistency better, but also reduce the sensitivity of spectral clustering to the kernel parameter, which improves the algorithm’s clustering performance. To efficiently apply the algorithm to image segmentation, the Nystrom method is used to reduce the computation complexity. Experimental results show that compared with traditional clustering algorithms and those popular spectral clustering algorithms, the proposed algorithm can achieve better clustering performances on several synthetic datasets, texture images and real images.

Non-circular plots of whole genomes are natural representations of genomic data aligned along all chromosomes.Currently,there is no specialized graphical user interface(GUI)designed to produce non-circular whole genome diagrams,and the use of existing tools requires considerable coding effort from users.Moreover,such tools also require improvement,including the addition of new functionalities.To address these issues,we developed a new R/Shiny application,named shiny Chromosome,as a GUI for the interactive creation of non-circular whole genome diagrams.shiny Chromosome can be easily installed on personal computers for own use as well as on local or public servers for community use.Publication-quality images can be readily generated and annotated from user input using diverse widgets.shiny Chromosome is deployed at http://150.***.59.144:3838/shiny Chromosome/,http://shiny ***,and https://yimingyu.***.io/shiny Chromosome for online use.The source code and manual of shiny Chromosome are freely available at https://***/venyao/shiny Chromosome.

Due to the potential risk of antibiotics to the environment,the development of inexpensive,simple,and reliable antibiotic detection methods is significant but also faces challenges.In this work,several lanthanide-organic frameworks(LOFs),constructed from lanthanide ions(Eu3+and/or Tb3+)and 1,3,5-benzene-tricarboxylic acid(BTC),were synthesized by solvothermal method.LOF-S3 with comparable emission peaks of 5D4→7F5(Tb3+,545 nm)and 5D0→7F2(Eu3+,618 nm)was selected as a luminescent sensor.In this system,the highly efficient energy transferred from the organic linker to lanthanide ions and from Tb3+to Eu3+occurs.LOF-S3 sensor was capable of decoding antibiotics by distinguishable emission intensity ratios.Therefore,a two-dimensional decoded map of antibiotics was established.The linear relationship between antibiotic concentration and emission intensity ratio indicated the quantitative determination of antibiotics was feasible.As a typical analyte,the response mechanism of nalidixic acid(NA)was investigated in detail.The competition of NA and BTC for UV light absorption,as well as the binding propensity of NA and Tb,affected the organic linkers-to-lanthanide ions and Tb-to-Eu energy transfer,resulting in the change of fluorescence intensity ratio.The self-calibrating mixed-LOF sensor overcame the uncontrollable errors of the traditional absolute emission intensity method and generated stable luminescent signals in multiple cycles.Furthermore,the integration of LOF-S3 with polymer fibers enabled the formation of a LOF-polymer fibrous composite with fluorescence detection capability,which is a promising portable sensor for practical applications.

In this paper,we propose a new method to estimate the diffusion function in the jump-diffusion model.First,a threshold reweighted Nadaraya-Watson-type estimator is introduced.Then,we establish asymptotic normality for the estimator and conduct Monte Carlo simulations through two examples to verify the better finite-sampling properties.Finally,our estimator is demonstrated through the actual data of the Shanghai Interbank Offered Rate in China.

Oscillator phase noise is one of the bottlenecks that limits the self-interference(SI)cancellation capability of full-duplex systems.In this paper,we propose a method for the suppression of common phase error(CPE)and intercarrier interference(ICI)induced by the phase noise in full-duplex orthogonal frequency division multiplexing(OFDM)systems.First,we regard the effect of CPE as a portion of the SI channel and perform estimation,reconstruction and elimination in the time domain.Then,the ICI signal is estimated and suppressed in the frequency domain.Additionally,by analysing the performance of proposed algorithm,we further develop an iterative mechanism to reduce the parameter estimation error and improve SI cancellation capability.Simulation results show that the proposed method has a significant SI cancellation capability improvement over the traditional SI cancellation schemes.

Anumber of therapies have been developed in the past decades.About two thirds of patients can be seizure free with antiepileptic drugs.1 Other patients are drug resistant,some of whom are good candidates for epileptic focus resection and become seizure free after surgery.2 The treatment for drug-resistant patients who are not eligible for resection is still challenging.Traditionally,these patients can receive palliative surgery such as callosotomy and multiple subpial transection,3,4 but the long-term outcomes of these procedures are not satisfactory.5-7 In the past decades,neuromodulation techniques have been applied in the treatment of epilepsy.Much evidence has been accumulated about the therapeutic effects of vagus nerve stimulation for epilepsy.In contrast to peripheral nerve stimulation,brain stimulation techniques have also been developed for patients with epilepsy recently.

Background:1,2,3,4,6-penta-O-galloyl-beta-D-glucose(PGG)is a natural polyphenolic compound derived from multiple medicinal plants with favorable anticancer activity.Methods:In this study,the mechanisms of PGG against gastric cancer were explored through network pharmacology and molecular docking.First,the targets of PGG were searched in the Herbal Ingredients’Targets(HIT),Similarity Ensemble Approach(SEA),and Super-PRED databases.The potential targets related to gastric cancer were predicted from the Human Gene Database(GeneCards)and DisGeNET databases.The intersecting targets of PGG and gastric cancer were obtained by Venn diagram and then subjected to protein-protein interaction analysis to screen hub targets.Functional and pathway enrichment of hub targets were analyzed through Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway databases.The differential expression and survival analysis of hub targets in gastric cancer were performed based on The Cancer Genome Atlas database.Finally,the affinity of PGG with hub targets was visualized by molecular docking.Results:Three hub targets were screened,including mitogen-activated protein kinase 14(MAPK14),BCL2 like 1(BCL2L1),and vascular endothelial growth factor A(VEGFA).MAPK14 had a higher expression,while BCL2L1 and VEGFA had lower expression in gastric cancer than in normal conditions.Enrichment analysis indicated enrichment of these hub targets in MAPK,neurotrophin,programmed death-ligand 1(PD-L1)checkpoint,phosphatidylinositol 3-kinases/protein kinase B(PI3K-Akt),Ras,and hypoxia-inducible factor-1(HIF-1)signaling pathways.Conclusion:Therefore,network pharmacology and molecular docking analyses revealed that PGG exerts a therapeutic efficacy on gastric cancer by multiple targets(MAPK14,BCL2L1,and VEGFA)and pathways(MAPK,PD-L1 checkpoint,PI3K-Akt,Ras,and HIF-1 pathways).

In contrast to typical planktonic hydromedusae,Cladonema medusae are mostly benthic,with specialised adhesive branches to adhere to the substrate.In this study,a Cladonema species discovered in a laboratory aquarium in Fuzhou,China,was confirmed as a new species,based on morphological and molecular analyses.The species was named Cladonema multiramosum sp.nov.Its medusa is distinct from that of congeners possessing substantially more adhesive branches(8-24,rarely 5-7),and tiny branches on the upper radial canals.The validity of C.multiramosumum sp.***.was also supported by molecular phylogenetic analyses based on the mitochondrial 16S rDNA sequence.However,C.multiramosum sp.***.medusa also displayed considerable phenotypic plasticity with respect to its radial canals,tentacles,stinging branches per tentacle,oral tentacles,manubrium,and gonads,hindering species identification based solely on morphology.Although some morphological characteristics of hydroids(filiform tentacles and medusa buds)and nematocysts could also be used as diagnostic characters in the genus Cladonema,this information is unavailable for some Cladonema species.Thus,the taxonomy within the genus Cladonema was re-evaluated based mainly on the morphological characteristics of the medusa.Further revision of the genus Cladonema should be made when supplementary information on the life cycle and DNA barcoding are updated.
