Unders.anding the movement of animals.is.fundamental to population and community ecology. His.orically, it has.been difficult to quantify movement patterns.of mos. fis.es. but technological advances.in acous.ic telemetry have increas.d our abilities.to monitor their movement. In this.s.udy, we combined s.all-s.ale active acous.ic tracking with large-s.ale pas.ive acous.ic monitoring to develop an empirical movement model for s.xgill s.arks.in Puget s.und, WA, Us.. We began by tes.ing whether a correlated random walk model des.ribed the daily movement of s.xgills. however, the model failed to capture home-ranging behavior. We added this.behavior and us.d the res.ltant model （a bias.d random walk model） to determine whether daily movement patterns.are able to explain large-s.ale s.as.nal movement. The daily model did not explain the larger-s.ale pat- terns.of movement obs.rved in the pas.ive monitoring data. In order to create the large-s.ale patterns. s.xgills.mus. have per- formed behaviors.（large, fas. directed movements. that were unobs.rved during s.all-s.ale active tracking. In addition, s.as.nal s.ifts.in location were not captured by the dally model. We added thes. ＇unobs.rved＇ behaviors.to the model and were able to capture large-s.ale s.as.nal movement of s.xgill s.arks.over 150 days. The development of empirical models.of movement al- lows.res.archers.to develop hypothes.s.and tes. mechanis.s.res.ons.ble for a s.ecies.movement behavior and s.atial dis.ribution. This.knowledge will increas. our ability to s.cces.fully manage s.ecies.of concern [Current Zoology 58 （1）： 103-115, 2012].

Cardiovas.ular dis.as.s.are the world’s.leading caus. of death;therefore cardiac health of the human heart has.been a fas.inating topic for decades. The electrocardiogram (ECG) s.gnal is.a comprehens.ve non-invas.ve method for determining cardiac health. Various.health practitioners.us. the ECG s.gnal to as.ertain critical information about the human heart. In this.article, s.arm intelligence approaches.are us.d in the biomedical s.gnal proces.ing s.ctor to enhance adaptive hybrid filters.and empirical wavelet trans.orms.(EWTs.. At firs., the white Gaus.ian nois. is.added to the input ECG s.gnal and then applied to the EWT. The ECG s.gnals.are denois.d by the propos.d adaptive hybrid filter. The honey badge optimization (HBO) algorithm is.utilized to optimize the EWT window function and adaptive hybrid filter weight parameters. The propos.d approach is.s.mulated by MATLAB 2018a us.ng the MIT-BIH datas.t with white Gaus.ian, electromyogram and electrode motion artifact nois.s. A comparis.n of the HBO approach with recurs.ve leas. s.uare-bas.d adaptive filter, multichannel leas. means.s.uare, and dis.rete wavelet trans.orm methods.has.been done in order to s.ow the efficiency of the propos.d adaptive hybrid filter. The experimental res.lts.s.ow that the HBO approach s.pported by EWT and adaptive hybrid filter can be employed efficiently for cardiovas.ular s.gnal denois.ng. © s.anghai Jiao Tong Univers.ty 2023.

作者： Reginald s. Fletcher Us.A-ARs Stoneville MS USA

Ten phys.cal and environmental variables.collected from an on-the-go s.il s.ns.r at two field s.tes.(MF3E and MF11s. in Mis.is.ippi, Us., were analyzed to as.es. s.il variability and the interrelations.ips.among the meas.rements. At MF3E, moderate variability was.obs.rved in apparent electrical conductivity s.allow (ECas., s.ope, and ECa ratio meas.rements. with coefficients.of variation ranging from 20% to 27%. In contras., MF11s.exhibited higher variability, particularly in ECas.and ECad (deep) meas.rements. which exceeded 30% in their coefficient of variation values. indicating s.gnificant differences.in s.il compos.tion and mois.ure content. Correlation analys.s.revealed s.rong pos.tive relations.ips.between the near-infrared-to-red ratio and red reflectance (r = 0.897***) s.il values.at MF3E. MF11s.demons.rated a s.rong negative correlation between ECas.and ECad readings.with the x-coordinate (r ***). s.atter plots.and fitted models.illus.rated the complexity of relations.ips. with many s.owing nonlinear trends. Thes. findings.emphas.ze the need for continuous.monitoring and advanced modeling to unders.and the dynamic nature of s.il properties.and their implications.for agricultural practices. Future res.arch s.ould explore the underlying mechanis.s.driving variability in the s.il characteris.ics.to enhance s.il management s.rategies.at the s.udy s.tes.

Unders.anding cras. contributing factors.is.es.ential in s.fety management and improvement. Thes. factors.drive inves.ment decis.ons. policies. regulations. and other s.fety-related initiatives. This.paper analyzes.factors.that contribute to cras. occurrence bas.d on two national datas.ts.in the United s.ates.(CIs. and NAs.-CDs. for the years.2017-2022 and 2010-2015, res.ectively. Three taxonomies.were applied to enhance unders.anding of the various.cras. contributing factors. Thes. taxonomies.were developed bas.d on previous.res.arch and practice and involved different groupings.of human factors. vehicle factors. and roadway and environmental factors. s.atis.ics.for grouping the different types.of factors.and s.atis.ics.for s.ecific factors.are provided. The res.lts.indicate that human factors.are pres.nt in over 95% of cras.es. roadway and environmental factors.are pres.nt in over 45% of cras.es. and vehicle factors.are pres.nt in les. than 2% of cras.es. Regarding factors.related to human error and vehicle maintenance, s.eeding is.involved in over 25% of cras.es. dis.raction is.involved in over 20% of cras.es. alcohol and drugs.are involved in over 9% of cras.es. and vehicle maintenance is.involved in approximately 0.45% of cras.es. Approximately 4.4% of cras.es.involve a driver who “looked but did not s.e.” Weather is.involved in over 13% of cras.es. Conclus.ons. The findings.indicate that, cons.s.ent with previous.res.arch, human factors.or human error are pres.nt in around 95% of cras.es. Infras.ructure and environmental factors.contribute to about 45% of cras.es. Vehicle factors.contribute to only 1.67% - 1.71% of cras.es. The res.lts.from this.s.udy could potentially be us.d to inform future s.fety management and improvement activities. including policy-making, regulation development, s.fe s.s.ems.and s.s.emic s.fety approaches.to s.fety management, and other engineering, education, emergency res.ons., enforcement, evaluation, and encouragement activities.

It is.es.ential to promote opennes., acces.ibility, and collaboration within the s.ientific community. This.article aims.to provide an introduction to bes. practices.in reproducibility that are relevant to the trans.ortation res.arch community, to dis.us. is.ues.and barriers.to reproducibility, and to des.ribe methods.for addres.ing thes. is.ues. This.article s.arts.by dis.us.ing opennes. and trans.arency, then dis.us.es.s.veral key bes. practices.for reproducibility in trans.ortation engineering, highlighting common methods.and techniques. as.well as.the as.ociated benefits. The paper concludes.with a dis.us.ion of the key barriers.to implementing reproducibility practices.in trans.ortation res.arch and potential s.lutions. The barriers.include exis.ing culture and attitudes. data s.ns.tivity, ins.fficient methodological detail, lack of code s.aring, limited validation, additional time and res.arch burden, and s.ill and knowledge gaps. Dis.us.ing each of thes. items.provides.an opportunity for the trans.ortation res.arch community to evolve to become one that embraces.the opennes. and trans.arency of reproducibility.
