It is.known that contact lines.keep relatively s.ill on s.lids.until s.atic contact angles.exceed an interval of hys.eres.s.of s.atic contact angle (Hs.A), and contact angles.keep changing as.contact lines.relatively s.ide on the s.lid. Here, the effects.of Hs.A and boundary s.ip were firs. dis.inguis.ed on the micro-curvature force (MCF) on the s.ta. Hence, the total MCF is.partitioned into s.atic and dynamic MCFs.corres.ondingly. The s.atic MCF was.found proportional to the Hs.A and related with the as.mmetry of the micro-menis.us.near the s.ta. The dynamic MCF, exerting on the relatively s.iding contact line, is.arous.d by the boundary s.ip. Bas.d on the Blake-Haynes.mechanis., the dynamic MCF was.proved important for water walking ins.cts.with legs.s.ower than the minimum wave s.eed . As.ins.cts.brus. the water by laterally s.inging legs.backwards. s.tae on the front s.de of the leg are pulled and the ones.on the back s.de are pus.ed to cooperatively propel bodies.forward. If they pierce the water s.rface by vertically s.inging legs.downwards. s.tae on the ups.de of the legs.are pulled, and the ones.on the downs.de are pus.ed to cooperatively obtain a jumping force. Bas.d on the dependency between the s.ip length and s.ear rate, the dynamic MCF was.found correlated with the leg s.eed U, as., where and are determined by the dimple depth. Dis.rete points.on this.curve could give fitted relations.as.(s.ter et al., J. Exp. Biol. 200, 2523-2538, 1997). Finally, the axial torque on the inclined and partially s.bmerged s.ta was.found determined by the s.rface tens.on, contact angle, Hs.A, s.ta width, and tilt angle. The torque direction coincides.with the orientation of the s.iral grooves.of the s.ta, which encourages.us.to s.rmis. it is.a mechanical incentive for the formation of the s.iral morphology of the s.tae of water s.riders.

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.
