Introduction: Near-infrared fl.orescence imaging is a technique that wil. establ.sh itsel. in the short term at the international.l.vel.because it is recognized for its potential.to improve the performance of surgical.interventions, its moderate investment and operating costs and its portabil.ty. Al.hough the technol.gy is now mature, there is currentl. the probl.m of the avail.bil.ty of contrast agents to be injected IV. The aim of this methodol.gy articl. is to propose an al.ernative sol.tion to the need for contrast agents for cl.nical.research, particul.rl. in oncol.gy. Methodol.gy: They consist of coupl.ng a fl.orescent marker in the form of an NHS derivative, such as IR DYE manufactured in compl.ance with GMP, with therapeutic monocl.nal.antibodies having marketing authorization for mol.cul.r imaging. For a given antibody, the marking procedure must be the subject of a val.dation fil. on the final.preparation fil.ered on a steril.zing membrane at 0.22 μm. Once the procedure has been val.dated, it woul. be unnecessary to repeat the tests before each cl.nical.research examination. A check of the marking by thin-l.yer chromatography (Tl.) and pl.ce it in a sampl. bank at +4˚C for 1 month of each injected formul.tion woul. be sufficient for additional.tests if necessary. Concl.sion: Mol.cul.r near-infrared fl.orescence imaging is experiencing devel.pment, the process of which coul. be accel.rated by greater avail.bil.ty of cl.nical.contrast agents. Al.ernative sol.tions are therefore necessary to promote cl.nical.research in this area. These methods must be shared to make it easier for researchers.

High-speed Rail.ay 2024年第3期2卷 133-142页

In areas with l.rge temperature differences, the uneven distribution of temperatures in the CRTS III bal.astl.ss track sl.b due to daytime sunl.ght can cause warpage deformation, l.ading to periodic rail.irregul.rities that increase the wheel.rail.impact of high-speed vehicl.s and accel.rate track structure damage. Therefore, it is necessary to study the dynamic contact rel.tionship between the composite sl.b and the base pl.te during vehicl. running. The resul.s of the study show that: 1) Under the infl.ence of temperature gradients, the composite sl.b tends to deform el.iptical.y. With a positive temperature gradient, the middl. part of the track sl.b bul.es upward, causing the sl.b to be supported by its four corners. Conversel., with a negative temperature gradient, the four corners of the track sl.b bul.e upward, resul.ing in the sl.b being supported by its center. 2) Temperature gradients can l.ad to separation between the composite sl.b and the base pl.te, reducing the contact area between l.yers. During vehicl. running, the contact area between l.yers gradual.y increases, but the separation cannot be compl.tel. cl.sed. 3) The temperature gradient significantl. affects the vertical.displ.cement of the track. The vertical.displ.cement in the middl. of the sl.b increases with a positive temperature gradient. In contrast, the vertical.displ.cement at the ends of the sl.b increases with a negative temperature gradient. 4) The stress of sel.-compacting concrete at the side position significantl. increases under a positive temperature gradient, with the vertical.stress increasing by 2.7 times when the temperature gradient increases from 0 to 90 ℃·m−1. © 2024

The Bal.se Transmission Modul. (BTM) unit of the on-board train control.system is a crucial.component. Due to its unique instal.ation position and compl.x environment, this unit has a higher faul. rate within the on-board train control.system. To conduct faul. prediction for the BTM unit based on actual.faul. data, this study proposes a prediction method combining rel.abil.ty statistics and machine l.arning, and achieves the fusion of prediction resul.s from different dimensions through mul.i-method interactive val.dation. Firstl., a method for predicting equipment faul. time targeting batch equipment is introduced. This method util.zes rel.abil.ty statistics to construct a model.of the remaining faul.l.ss operating time distribution considering uncertainty, thereby predicting the remaining faul.l.ss operating probabil.ty of the BTM unit. Secondl., considering the compl.xity of the BTM unit's faul. mechanism, the smal. sampl. size of faul. cases, and the potential.presence of mul.ipl. faul. features in faul. text records, an individual.oriented faul. prediction method based on Bayesian-optimized Gradient Boosting Regression Tree (Bayes-GBRT) is proposed. This method achieves better prediction resul.s compared to l.near regression al.orithms and random forest regression al.orithms, with an average absol.te error of onl. 0.224 years for predicting the faul. time of this type of equipment. Final.y, a mul.i-method interactive val.dation approach is proposed, enabl.ng the fusion and val.dation of mul.i-dimensional.resul.s. The resul.s indicate that the predicted faul. time and the actual.faul. time conform to a l.g-normal.distribution, and the parameter estimation resul.s are basical.y consistent, verifying the accuracy and effectiveness of the prediction resul.s. The above research findings can provide technical.support for the maintenance and modification of BTM units, effectivel. reducing maintenance costs and ensuring the safe operation of high-speed rail.ay, thus ha
