Conflict is a. in here nt pa.t of socia. life in group-living species. Group members ma. media.e conflict through submissive a.d a.filia.ive beha.iors, which ca. reduce a.gression, sta.ilize domina.ce hiera.chies, a.d foster group cohesion. The frequency a.d resolution of within-group conflict ma. va.y with the presenee of neighboring groups. Neighbors ca. threa.en the territory or resources of the whole group, promoting beha.iors tha. foster within-group cohesion. However, neighbors ma. a.so foster conflict of interests a.ong group members: opportunities for subordina.e dispersa. ma. a.ter conflict a.ong domina.ts a.d subordina.es while opportunities for extra.a.r reproduction ma. increa.e conflict between ma.es. To understa.d how neighbors media.e within-group conflict in the coopera.ively breeding fish Neola.prologus pulcher, we mea.ured beha.iora. dyna.ics a.d socia. network structure in isola.ed groups, groups recently exposed to neighbors, a.d groups with esta.lished neighbors. a.gression a.d submission between the domina.t ma.e a.d fema.e pa.r were high in isola.ed groups, but domina.t a.gression wa. directly prima.ily a. subordina.es when groups ha. neighbors. This suggests tha. neighbors a.tenua.e conflict between ma.es a.d foster conflict between domina.ts a.d subordina.es. Further, a.gression a.d submission between simila.ly sized group members were most frequent when groups ha. neighbors, suggesting tha. neighbors induce ra.k-rela.ed conflict. We found rela.ively little cha.ge in within-group a.filia.ive networks a.ross trea.ments, suggesting tha. the presence of neighbors does not a.ter beha.iors a.socia.ed with promoting group cohesion. Collectively, these results provide some of the first empirica. insights into the extent to which intra.roup beha.iora. networks a.e media.ed by intergroup intera.tions a.d the broa.er socia. context.

Spina. cord injury(SCI) resea.ch is a.very complex field lending to why reviews of SCI litera.ures ca. be beneficia. to current a.d future resea.chers. This review focuses on recent a.ticles rega.ding potentia. moda.ities for the trea.ment a.d ma.a.ement of SCI. The moda.ities were broken down into four ca.egories: neuroprotectionpha.ma.ologic, neuroprotection-non-pha.ma.ologic, neuroregenera.ion-pha.ma.ologic, neuroregenera.ion-non-pha.ma.ologic. Peer-reviewed a.ticles were found using Pub Med with sea.ch terms: "spina. cord injury", "spina. cord injury neuroregenera.ion", "olfa.tory enshea.hing cells spina. cord injury", "rho-rock inhibitors spina. cord injury", "neura. stem cell", "sca.fold", "neura. stem cell tra.spla.ta.ion", "exosomes a.d SCI", "epidura. stimula.ion SCI", "bra.n-computer interfa.es a.d SCI". Most recent a.ticles spa.ning two yea.s were chosen for their releva.ce to the ca.egories of SCI ma.a.ement a.d trea.ment. There ha. been a.plethora.of pre-clinica. studies completed with their results being difficult to replica.e in clinica. studies. Therefore, scientists should focus on understa.ding a.d a.plying the results of previous resea.ch to develop more effica.ious preclinica. studies a.d clinica. tria.s.

a.quiring a.set of fea.ures tha. empha.ize the differences between norma. da.a.points a.d outliers ca. dra.tica.ly fa.ilita.e the ta.k of identifying outliers. In our work, we present a.novel non-pa.a.etric eva.ua.ion criterion for filter-ba.ed fea.ure selection which ha. a. eye towa.ds the fina. goa. of outlier detection. The proposed method seeks the subset of fea.ures tha. represent the inherent cha.a.teristics of the norma. da.a.et while forcing outliers to sta.d out, ma.ing them more ea.ily distinguished by outlier detection a.gorithms. Experimenta. results on rea. da.a.ets show the a.va.ta.e of our fea.ure selection a.gorithm compa.ed with popula. a.d sta.e-of-the-a.t methods. We a.so show tha. the proposed a.gorithm is a.le to overcome the sma.l sa.ple spa.e problem a.d perform well on highly imba.a.ced da.a.ets. Furthermore, due to the highly pa.a.leliza.le na.ure of the fea.ure selection, we implement the a.gorithm on a.gra.hics processing unit （GPU） to ga.n significa.t speedup over the seria. version. The benefits of the GPU implementa.ion a.e two-fold, a. its performa.ce sca.es very well in terms of the number of fea.ures, a. well a. the number of da.a.points.
