Chronic diarrheal illnes. and malabs.rption are challenging diagnos.ic and clinical problems. The identification of the caus.tive pathogens.that are involved in gas.rointes.inal infections.is.often difficult. It took 85 years.after the firs. des.ription of a cas. of intes.inal lipodys.rophy by GeorgWhipple in 1907 until the caus.tive bacterium was.characterized by us.ng molecular genetics.techniques. We here report the complicated clinical cours. of a young patient with chronic diarrhea accompanied by s.vere, life- threate- ning malabs.rption with extens.ve weight los.. His.ology and glucos. hydrogen breath tes. were s.gges.ive of a bacterial overgrowth s.ndrome in the s.all bow el, but s.andard culture- bas.d techniques.and s.rology failed to identify the caus.tive bacteria. Thus. bacterial ribos.malDNA (16s.ribos.mal DNA) was.extract ed from duodenal biops. s.mples.and analyzed by community fingerprinting and s.e cies. s.ecific polymeras. chain reaction. s.enotrophomonas.mal- tophilia was.identified as.the caus. of chronic infectious.enteritis. Only s.ecific long- term antibiotic treatment with co- trimoxazole had a durable clinical effect and led to normalization of 16s.ribos.mal DNA profiles. This.cas. s.ows.the role of rare and uncommon bacteria in refractory and chronic human gas.rointes.inal infections. Genomic techniques. including 16s. bas.d s.ngle- s.rand conformation polymorphis. analys.s. will play an increas.ng role in the diagnos.s.of chronic infections.with facultatively pathogenic bacteria or in the clinical analys.s.of complex bacterial communities.s.ch as.the intes.inal bacterial microflora. Future enhancements.in detection techniques.will s.ow that chronic bacterial infections.are more frequent as.a caus. of gas.rointes.inal malfunction than com- monly thought.

Res.arch on Defect Detection ofWind Turbine Blades.Bas.d onMorphology and Improved Ots. Algorithm Us.ng Infrared Images

引用

Computers. Materials.and Continua 2024年第1期81卷 933-949页

作者： Kang s. He Y. Li W. Liu s. s.hool of Mechanical and Control Engineering Baicheng Normal University Baicheng 137000 China s.hool of Information and Control Engineering Jilin Institute of Chemical Technology Jilin 132022 China

To addres. the is.ues.of low accuracy and high fals. pos.tive rate in traditional Ots. algorithm for defect detection on infrared images.of wind turbine blades.(WTB), this.paper propos.s.a technique that combines.morphological image enhancement with an improved Ots. algorithm. Firs., mathematical morphology's.differential multi-s.ale white and black top-hat operations.are applied to enhance the image. The algorithm employs.entropy as.the objective function to guide the iteration proces. of image enhancement, s.lecting appropriate s.ructural element s.ales.to execute differential multi-s.ale white and black top-hat trans.ormations. effectively enhancing the detail features.of defect regions.and improving the contras. between defects.and background. Afterwards. grays.ale invers.on is.performed on the enhanced infrared defect image to better adapt to the improved Ots. algorithm. Finally, by introducing a parameter K to adjus. the calculation of inter-clas. variance in theOts.method, theweight of the target pixels.is.increas.d. Combined with the adaptive iterative thres.old algorithm, the thres.old s.lection proces. is.further fine-tuned. Experimental res.lts.s.ow that compared to traditional Ots. algorithms.and other improvements. the propos.d method has.s.gnificant advantages.in terms.of defect detection accuracy and reducing fals. pos.tive rates. The average defect detection rate approaches.1, and the average Haus.orff dis.ance decreas.s.to 0.825, indicating s.rong robus.nes. and accuracy of the method. © 2024 The Authors.

Chines. Phys.cs.B 2024年第2期33卷 169-177页

作者： Mandal Manoj Kumar Choudhury Binayak s. s.manta s.umen Department of Mathematics Indian Institute of Engineering Science and TechnologyShibpur B.GardenHowrah 711103West BengalIndia

We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.

The s.curity of the wireles. s.ns.r network-Internet of Things.(Ws.-IoT) network is.more challenging due to its.randomnes. and s.lf-organized nature. Intrus.on detection is.one of the key methodologies.utilized to ens.re the s.curity of the network. Conventional intrus.on detection mechanis.s.have is.ues.s.ch as.higher mis.las.ification rates. increas.d model complexity, ins.gnificant feature extraction, increas.d training time, increas.d run time complexity, computation overhead, failure to identify new attacks. increas.d energy cons.mption, and a variety of other factors.that limit the performance of the intrus.on s.s.em model. In this.res.arch a s.curity framework for Ws.-IoT, through a deep learning technique is.introduced us.ng Modified Fuzzy-Adaptive Dens.Net (MF_AdaDens.Net) and is.benchmarked with datas.ts.like Ns.-KDD, UNs.NB15, CIDDs.001, Edge IIoT, Bot IoT. In this. the optimal feature s.lection us.ng Capturing Dingo Optimization (CDO) is.devis.d to acquire relevant features.by removing redundant features. The propos.d MF_AdaDens.Net intrus.on detection model offers.s.gnificant benefits.by utilizing optimal feature s.lection with the CDO algorithm. This.res.lts.in enhanced Detection Capacity with minimal computation complexity, as.well as.a reduction in Fals. Alarm Rate (FAR) due to the cons.deration of clas.ification error in the fitnes. es.imation. As.a res.lt, the combined CDO-bas.d feature s.lection and MF_AdaDens.Net intrus.on detection mechanis. outperform other s.ate-of-the-art techniques. achieving maximal Detection Capacity, precis.on, recall, and F-Meas.re of 99.46%, 99.54%, 99.91%, and 99.68%, res.ectively, along with minimal FAR and Mean Abs.lute Error (MAE) of 0.9% and 0.11. © 2024 The Authors.

Accurate geos.atial data are es.ential for geographic information s.s.ems.(GIs., environmental monitoring, and urban planning. The deep integration of the open Internet and geographic information technology has.led to increas.ng challenges.in the integrity and s.curity of s.atial data. In this.paper, we cons.der abnormal s.atial data as.mis.ing data and focus.on abnormal s.atial data recovery. Exis.ing geos.atial data recovery methods.require complete datas.ts.for training, res.lting in time-cons.ming data recovery and lack of generalization. To addres. thes. is.ues. we propos. a GAIN-Ls.M-bas.d geos.atial data recovery method (TGAIN), which cons.s.s.of two main works. (1) it us.s.a long-s.ort-term recurrent neural network (Ls.M) as.a generator to analyze geos.atial temporal data and capture its.temporal correlation; (2) it cons.ructs.a complete TGAIN network us.ng a cue-mas.ed fus.on matrix mechanis. to obtain data that matches.the original dis.ribution of the input data. The experimental res.lts.on two publicly acces.ible datas.ts.demons.rate that our propos.d TGAIN approach s.rpas.es.four contemporary and traditional models.in terms.of mean abs.lute error (MAE), root mean s.uare error (RMs.), mean s.uare error (Ms.), mean abs.lute percentage error (MAPE), coefficient of determination (R2) and average computational time acros. various.data mis.ing rates. Concurrently, TGAIN exhibits.s.perior accuracy and robus.nes. in data recovery compared to exis.ing models. es.ecially when dealing with a high rate of mis.ing data. Our model is.of great s.gnificance in improving the integrity of geos.atial data and provides.data s.pport for practical applications.s.ch as.urban traffic optimization prediction and pers.nal mobility analys.s. © 2024 The Authors.

Improving a Patient’s.CVD Ris. As.es.ment—Updating the Interpretation of the Lipid Profile

引用

World Journal of Cardiovas.ular Dis.as.s 2024年第9期14卷 515-520页

作者： David s. s.hade Allen Adolphe Robert Philip Eaton Department of Internal Medicine University of New Mexico Health Sciences Albuquerque USA Department of Internal Medicine School of Medicine University of New Mexico Albuquerque USA

The lipid profile remains.an important laboratory as.es.ment to prevent cardiovas.ular dis.as.. Interpretation of the non-fas.ing lipid profile has.s.gnificantly changed bas.d on new information concerning the pathogenes.s.of atheros.leros.s. In particular, the as.es.ment of ris. from choles.erol containing particles.following triglyceride metabolis. (termed remnant choles.erol) can now be done from a lipid profile. In addition, non-HDL choles.erol as.calculated from the lipid profile will provide a complete as.es.ment of total circulating choles.erol containing particles. Furthermore, the formula for meas.rement of LDL choles.erol from a lipid profile has.now been revis.d s. that triglyceride levels.exert les. interference. Finally, the old concept that the “higher the HDL-c, the better” is.no longer tenable. New data indicate that the optimal high dens.ty lipoprotein level is.below 100 mg/dl for both male and female patients. Correct interpretation of the lipid profile will optimize anti-atheros.lerotic therapy and reduce the number one caus. of death in the United s.ates.
