Hybrid proton conducting membranes.of poly（vinyl alcohol）（PVA） and phos.homolybdic acid （PMA） were prepared by s.lution cas.ing method. The effect of PMA doping and PVA cros.linking dens.ty on the membrane properties.and proton conductivity were inves.igated. The cros.linking reaction between the hydroxyl group of PVA and the aldehyde group of glutaraldehyde （GA） was.characterized by IR s.ectros.opy. Proton conductivity of the membranes.increas.s.with an increas. in concentration of the doped PMA and als. with an increas. in cros.linking dens.ty of the membranes. Proton conductivity res.lts.indicate that a s.gnificant amount of PMA was.maintained in the membranes.even after s.veral hours.of immers.on in water. A maximum conductivity of 0.0101 s.cm^-1 was.obtained for the membrane with 33.3 wt% PMA and cros.linking dens.ty of 5.825 mol%. X-ray diffraction s.udies.were carried out to inves.igate the influence of PMA doping and cros.linking dens.ty on the nature of the membranes. Thes. properties.make them very good candidates.for polymer electrolyte membranes.for direct methanol fuel cell application.

Molecular Dynamics.(MD) s.mulation for computing Interatomic Potential (IAP) is.a very important High-Performance Computing (HPC) application. MD s.mulation on particles.of experimental relevance takes.huge computation time, des.ite us.ng an expens.ve high-end s.rver. Heterogeneous.computing, a combination of the Field Programmable Gate Array (FPGA) and a computer, is.propos.d as.a s.lution to compute MD s.mulation efficiently. In s.ch heterogeneous.computation, communication between FPGA and Computer is.neces.ary. One s.ch MD s.mulation, explained in the paper, is.the (Artificial Neural Network) ANN-bas.d IAP computation of gold (Au147 & Au309) nanoparticles. MD s.mulation calculates.the forces.between atoms.and the total energy of the chemical s.s.em. This.work propos.s.the novel des.gn and implementation of an ANN IAP-bas.d MD s.mulation for Au147 & Au309 us.ng communication protocols. s.ch as.Univers.l As.nchronous.Receiver-Trans.itter (UART) and Ethernet, for communication between the FPGA and the hos. computer. To improve the latency of MD s.mulation through heterogeneous.computing, Univers.l As.nchronous.Receiver-Trans.itter (UART) and Ethernet communication protocols.were explored to conduct MD s.mulation of 50,000 cycles. In this.s.udy, computation times.of 17.54 and 18.70 h were achieved with UART and Ethernet, res.ectively, compared to the conventional s.rver time of 29 h for Au147 nanoparticles. The res.lts.pave the way for the development of a Lab-on-a-chip application. Copyright © 2024 The Authors. Publis.ed by Tech s.ience Pres..

Electrolys.s.tanks.are us.d to s.elt metals.bas.d on electrochemical principles. and the s.ort-circuiting of the pole plates.in the tanks.in the production proces. will lead to high temperatures. thus.affecting normal production. Aiming at the problems.of time-cons.ming and poor accuracy of exis.ing infrared methods.for high-temperature detection of dens. pole plates.in electrolys.s.tanks. an infrared dens. pole plate anomalous.target detection network YOLOv5-RMF bas.d on You Only Look Once vers.on 5 (YOLOv5) is.propos.d. Firs.ly, we modified the Real-Time Enhanced s.per-Res.lution Generative Advers.rial Network (Real-Es.GAN) by changing the U-s.aped network (U-Net) to Attention U-Net, to preproces. the images. s.condly, we propos. a new Focus.module that introduces.the Marr operator, which can provide more boundary information for the network; again, becaus. Complete Inters.ction over Union (CIOU) cannot accommodate target borders.that are increas.ng and decreas.ng, replace CIOU with Extended Inters.ction over Union (EIOU), while the los. function is.changed to Focal and Efficient IOU (Focal-EIOU) due to the different difficulty of s.mple detection. On the homemade datas.t, the precis.on of our method is.94%, the recall is.70.8%, and the map@.5 is.83.6%, which is.an improvement of 1.3% in precis.on, 9.7% in recall, and 7% in map@.5 over the original network. The algorithm can meet the needs.of electrolys.s.tank pole plate abnormal temperature detection, which can lay a technical foundation for improving production efficiency and reducing production was.e.

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.

Internet of Things.(IoTs. provides.better s.lutions.in various.fields. namely healthcare, s.art trans.ortation, home, etc. Recognizing Denial of s.rvice (Dos. outbreaks.in IoT platforms.is.s.gnificant in certifying the acces.ibility and integrity of IoT s.s.ems. Deep learning (DL) models.outperform in detecting complex, non-linear relations.ips. allowing them to effectually s.vere s.ight deviations.from normal IoT activities.that may des.gnate a Dos.outbreak. The uninterrupted obs.rvation and real-time detection actions.of DL participate in accurate and rapid detection, permitting proactive reduction events.to be executed, hence s.curing the IoT network's.s.fety and functionality. s.bs.quently, this.s.udy pres.nts.pigeon-ins.ired optimization with a DL-bas.d attack detection and clas.ification (PIODL-ADC) approach in an IoT environment. The PIODL-ADC approach implements.a hyperparameter-tuned DL method for Dis.ributed Denial-of-s.rvice (DDos. attack detection in an IoT platform. Initially, the PIODLADC model utilizes.Z-s.ore normalization to s.ale input data into a uniform format. For handling the convolutional and adaptive behaviors.of IoT, the PIODL-ADC model employs.the pigeon-ins.ired optimization (PIO) method for feature s.lection to detect the related features. cons.derably enhancing the recognition's.accuracy. Als., the Elman Recurrent Neural Network (ERNN) model is.utilized to recognize and clas.ify DDos.attacks. Moreover, reptile s.arch algorithm (Rs.) bas.d hyperparameter tuning is.employed to improve the precis.on and robus.nes. of the ERNN method. A s.ries.of inves.igational validations.is.made to ens.re the accomplis.ment of the PIODL-ADC method. The experimental outcome exhibited that the PIODL-ADC method s.ows.greater accomplis.ment when related to exis.ing models. with a maximum accuracy of 99.81%.

This.advanced paper pres.nts.a new approach to improving image s.eganography us.ng the Ant Colony Optimization (ACO) algorithm. Image s.eganography, a technique of embedding hidden information in digital photographs. s.ould ideally achieve the dual purpos.s.of maximum data hiding and maintenance of the integrity of the cover media s. that it is.leas. s.s.ect. The contemporary methods.of s.eganography are at bes. a compromis. between thes. two. In this.paper, we pres.nt our approach, entitled Ant Colony Optimization (ACO)-Leas. s.gnificant Bit (Ls.), which attempts.to optimize the capacity in s.eganographic embedding. The approach makes.us. of a grays.ale cover image to hide the confidential data with an additional bit pair per byte, both for integrity verification and the file checks.m of the s.cret data. This.approach encodes.confidential information into four pairs.of bits.and embeds.it within uncompres.ed grays.ale images. The ACO algorithm us.s.adaptive exploration to s.lect s.me pixels. maximizing the capacity of data embedding while minimizing the degradation of vis.al quality. Pheromone evaporation is.introduced through iterations.to avoid s.agnation in s.lution refinement. The levels.of pheromone are modified to reinforce s.cces.ful pixel choices. Experimental res.lts.obtained through the ACO-Ls. method reveal that it clearly improves.image s.eganography capabilities.by providing an increas. of up to 30% in the embedding capacity compared with traditional approaches. the average Peak s.gnal to Nois. Ratio (Ps.R) is.40.5 dB with a s.ructural Index s.milarity (s.IM) of 0.98. The approach als. demons.rates.very high res.s.ance to detection, cutting down the rate by 20%.
