Detec.ing genotype-by-environment (GE) interac.ion effec.s or yield stability is one of the most important c.mponents for c.op trial data analysis, espec.ally in historic.l c.op trial data. However, it is statistic.lly c.allenging to disc.ver the GE interac.ion effec.s bec.use many published data were just entry means under eac. environment rather than repeated field plot data. In this study, we propose a new methodology, whic. c.n be used to impute replic.ted trial data sets to reveal GE interac.ions from the original data. As a demonstration, we used a data set, whic. inc.udes 28 potato genotypes and six environments with three replic.tions to numeric.lly evaluate the properties of this new imputation method. We c.mpared the phenotypic.means and predic.ed random effec.s from the imputed data with the results from the original data. The results from the imputed data were highly c.nsistent with those from the original data set, indic.ting that imputed data from the method we proposed in this study c.n be used to reveal information inc.uding GE interac.ion effec.s harbored in the original data. Therefore, this study c.uld pave a way to detec. the GE interac.ions and other related information from historic.l c.op trial reports when replic.tions were not available.

This paper adopts the NGI-ADP soil model to c.rry out finite element analysis,based on whic. the effec.s of soft c.ay anisotropy on the diaphragm wall deflec.ions in the brac.d exc.vation were *** than one thousand finite element c.ses were numeric.lly analyzed,followed by extensive parametric.*** models were developed via ensemble learning methods(ELMs),inc.uding the e Xtreme Gradient Boosting(XGBoost),and Random Forest Regression(RFR)to predic. the maximum lateral wall deformation(δhmax).Then the results of ELMs were c.mpared with c.nventional soft c.mputing methods suc. as Dec.sion Tree Regression(DTR),Multilayer Perc.ptron Regression(MLPR),and Multivariate Adaptive Regression Splines(MARS).This study presents a c.tting-edge applic.tion of ensemble learning in geotec.nic.l engineering and a reasonable methodology that allows engineers to determine the wall deflec.ion in a fast,alternative way.

The field of researc. on pain originating from various bone diseases is expanding rapidly, with new mec.anisms and targets asserting both peripheral and c.ntral sites of ac.ion. The sc.pe of researc. is broadening from bone biology to neurosc.enc.,neuroendoc.inology, and immunology. In partic.lar, the roles of primary sensory neurons and non-neuronal c.lls in the peripheral tissues as important targets for bone pain treatment are under extensive investigation in both pre-c.inic.l and c.inic.l settings. An understanding of the peripheral mec.anisms underlying pain c.nditions assoc.ated with various bone diseases will aid in the appropriate applic.tion and development of optimal strategies for not only managing bone pain symptoms but also improving bone repairing and remodeling, whic. potentially c.res the underlying etiology for long-term func.ional rec.very. In this review, we foc.s on advanc.s in important prec.inic.l studies of signific.nt bone pain c.nditions in the past 5 years that indic.ted new peripheral neuronal and non-neuronal mec.anisms, novel targets for potential c.inic.l interventions, and future direc.ions of researc..

Pt/c.c.talysts were prepared by ethylene glyc.l （EG） method in weakly ac.dic.solutions adjusted by sodium c.trate （Nasc.t）, sodium ac.tate （NaAc. and sodium hydroxide （NaoH）, separately. The effec.s of alkalizing agent, pH and temperature were investigated by transmission elec.ron mic.osc.py （TEM） and c.. The c.mposition and struc.ure of Pt/c.c.talyst prepared at optimal c.nditions of 140℃ and pH=6.7 adjusted by Nasc.t was further c.arac.erized by X-ray photoelec.ron mic.osc.py （XPS） and X-ray diffrac.ion （XRD）, respec.ively. The average partic.e size of Pt/c.c.talyst prepared using Na3c.t is 2.1 nm, smaller than that of Pt/c.c.talyst （2.9 nm） prepared using NaAc. muc. smaller than that of Pt/c.c.talyst （100 nm） prepared using NaoH. The elec.roc.talytic.ac.ivity of Pt/c.c.talysts prepared using Na3c.t and NaAc.for ethanol oxidation are 456.6 and 419.2 mA/mgPt, c.mparative to those of Pt/c.c.talyst prepared by typic.l EG method and c.mmerc.al E-TEK Pt/c.c.talyst.

It is generally believed that a thermally grown oxide (Too) layer of alumina provides enhanc.d protec.ion to the metallic.bond c.at in thermal barrier c.ating (TBc. systems at elevated temperatures. However, in an air-plasma-sprayed (APS) TBc.system with c.-32Ni-21c.-8Al-0.5Y (wt%) bond c.at, the TGo layer formed upon thermal exposure in air was predominantly c.romia and spinels, whic. would not effec.ively protec. the bond c.at at above 1000°c. In addition, mixed oxides of c.romia, spinel and nic.el oxide formed heterogeneously between the c.ramic.c.ating and c.Nic.AlY bond c.at, whic. would promote c.ac. initiation and lead to premature TBc.failure. A heat treatment in a low-pressure c.ndition was applied to the as-sprayed TBc.system, with the aim to produc. an alumina layer as well as reduc. the amount of detrimental oxides. The influenc. of this low-pressure oxidation treatment (LPoT) on the bond c.at c.c.ic.oxidation behaviour of the TBc.system was also investigated.
