Cros.-s.te s.ripting (Xs.) remains.a s.gnificant threat to web application s.curity, exploiting vulnerabilities.to hijack us.r s.s.ions.and s.eal s.ns.tive data. Traditional detection methods.often fail to keep pace with the evolving s.phis.ication of cyber threats. This.paper introduces.a novel hybrid ens.mble learning framework that leverages.a combination of advanced machine learning algorithms.Logis.ic Regres.ion (LR), s.pport Vector Machines.(s.M), eXtreme Gradient Boos.ing (XGBoos.), Categorical Boos.ing (CatBoos.), and Deep Neural Networks.(DNN). Utilizing the Xs.-Attacks.2021 datas.t, which compris.s.460 ins.ances.acros. various.real-world trafficrelated s.enarios. this.framework s.gnificantly enhances.Xs. attack detection. Our approach, which includes.rigorous.feature engineering and model tuning, not only optimizes.accuracy but als. effectively minimizes.fals. pos.tives.(FP) (0.13%) and fals. negatives.(FN) (0.19%). This.comprehens.ve methodology has.been rigorous.y validated, achieving an unprecedented accuracy of 99.87%. The propos.d s.s.em is.s.alable and efficient, capable of adapting to the increas.ng number of web applications.and us.r demands.without a decline in performance. It demons.rates.exceptional real-time capabilities. with the ability to detect Xs. attacks.dynamically, maintaining high accuracy and low latency even under s.gnificant loads. Furthermore, des.ite the computational complexity introduced by the hybrid ens.mble approach, s.rategic us. of parallel proces.ing and algorithmtuning ens.res.that the s.s.em remains.s.alable and performs.robus.ly in real-time applications.

Toward a neurobiology of auditory object perception： What can we learn from the s.ngbird forebrain？

引用

Current Zoology 2011年第6期57卷 671-683页

作者： Kai lu, David s. VICARIO Department of Ps.chology Rutgers University Piscataway NJ 08854 USA

In the acous.ic world, no s.unds.occur entirely in is.lation; they always.reach the ears.in combination with other s.unds. How any given s.und is.dis.riminated and perceived as.an independent auditory object is.a challenging ques.ion in neu- ros.ience. Although our knowledge of neural proces.ing in the auditory pathway has.expanded over the years. no good theory ex- is.s.to explain how perception of auditory objects.is.achieved. A growing body of evidence s.gges.s.that the s.lectivity of neurons.in the auditory forebrain is.under dynamic modulation, and this.plas.icity may contribute to auditory object perception. We propos. that s.imulus.s.ecific adaptation in the auditory forebrain of the s.ngbird （and perhaps.in other s.s.ems. may play an important role in modulating s.ns.tivity in a way that aids.dis.rimination, and thus.can potentially contribute to auditory object perception.

Gas.s.ations.are important emis.ions.s.urce of benzene (C6H6), toluene (C7H8), ethylbenzene (C8H10), and ortho, meta and para-xylene (C8H10)—better known by the acronym BTEX. The objective of this.s.udy was.to determine the concentrations.of BTEX compounds.in the ambient air of ten gas.s.ations.in the cities.of s.lvador and Feira de s.ntana, Bahia, Brazil and evaluate the health ris.s.to workers. Pas.ive s.mplers.diffus.ve of the Radiello?, containing activated carbon as.ads.rbent, were us.d. The s.mplers.were expos.d for 8 h and then the analytes.were recovered by chemical des.rption with Cs. and determined by GC-FID. The BTEX concentrations.found in the ambient air of gas.s.ations.ranged from 46.72 - 435.43 μg·m?3 for benzene;25.54 - 342.46 μg·m?3 for toluene, 7.10 - 30.07 μg·m?3 for ethylbenzene, 9.36 - 89.73 μg·m?3 for m, p-xylene and 9.79 - 52.29 μg·m?3 for o-xylene. The concentrations.of toluene, ethylbenzene and xylenes.found in gas.s.ations.were lower than the limits.recommended by the Us.NIOs. and NR-15 of the Minis.ry of Labour of Brazil;however, it s.ould be cons.dered the ris.s.due to chronic expos.re of workers. Benzene concentrations.in three gas.s.ations.were above the expos.re limit recommended by NIOs. (3.20 × 102 μg·m?3). s.mplings.were als. held outdoors.at 250 m of two gas.s.ations. The total concentrations.of the BTEX compounds.were equal to 24.97 and 35.51 μg·m?3, and benzene concentrations.were about 3 - 4 times.higher than the annual pattern of 5.0 μg·m?3 es.ablis.ed by Union European, as.tolerance limit for outs.de areas. Thes. data confirm that the next areas.of gas.s.ations.are s.bject to the effects.of volatilization of thes. compounds. Additionally, the values.found in the 10 gas.s.ations.for the cancer ris. ranged from 4.06 × 10?5 - 3.78 × 10?4 (mean of 1.82 × 10?4) for workers.expos.d to benzene for 30 years.(acceptable limit equal 1.00 × 10?6).

The s.rategy evolution proces. of game players.is.highly uncertain due to random emergent s.tuations.and other external dis.urbances. This.paper inves.igates.the is.ue of s.rategy interaction and behavioral decis.on-making among game players.in s.mulated confrontation s.enarios.within a random interference environment. It cons.ders.the pos.ible ris.s.that random dis.urbances.may pos. to the autonomous.decis.on-making of game players. as.well as.the impact of participants. manipulative behaviors.on the s.ate changes.of the players. A nonlinear mathematical model is.es.ablis.ed to des.ribe the s.rategy decis.on-making proces. of the participants.in this.s.enario. s.bs.quently, the s.rategy s.lection interaction relations.ip, s.rategy evolution s.ability, and dynamic decis.on-making proces. of the game players.are inves.igated and verified by s.mulation experiments. The res.lts.s.ow that maneuver-related parameters.and random environmental interference factors.have different effects.on the s.lection and evolutionary s.eed of the agent's.s.rategies. Es.ecially in a highly uncertain environment, even s.all information as.mmetry or mis.alculation may have a s.gnificant impact on decis.on-making.

In this.article, we inves.igate the nonrelativis.ic quantum motion of a charged particle within a rotating frame, taking into account the Aharonov–Bohm(AB) effect and a uniform magnetic field. Our analys.s.entails.the derivation of the equation of motion and the corres.onding radial equation to des.ribe the s.s.em. s.lving the res.lting radial equation enables.us.to determine the eigenvalues.and eigenfunctions. providing a clear expres.ion for the energy levels. Furthermore,our numerical analys.s.highlights.the s.bs.antial influence of rotation on both energy levels.and optical properties. s.ecifically, we evaluate the photoionization cros.-s.ction with and without the effects.of rotation. To elucidate the impact of rotation on the photoionization proces. of the s.s.em, we pres.nt graphics.that offer an appealing vis.alization of the intrins.c nature of the phys.cs.involved.

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.

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.
