This.s.udy pres.nts.the res.lts.of an experimental inves.igation that compares.the mechanical properties. fracture behavior, creep, and s.rinkage of a chemically-bas.d s.lf-cons.lidating concrete （s.C） mix with that of a corres.onding conventional concrete （CC） mix. The CC and s.C mix des.gns.followed conventional proportioning in terms.of aggregate type and content, cement content, air content, water-cementitiuos.materials.（w/cm） ratio, and workability. Then, us.ng only chemical admixtures. the authors.converted the CC mix to an s.C mix with all of the neces.ary pas.ing, filling, flowability, and s.ability requirements.typically found in s.C. The high fluidity was.achieved with a polycarboxylate-bas.d high-range water-reducing admixture, while the enhanced s.ability was.accomplis.ed with an organic, polymer-bas.d vis.os.ty-modifying admixture. The comparis.n indicated that the s.C and CC mixes.had virtually identical tens.le s.litting s.rengths. flexural s.rengths. creep, and s.rinkage. However, the s.C mix s.owed higher compres.ive s.rengths.and fracture energies.than the corres.onding CC mix.

During the pas. decade, robotic s.rgical s.s.ems.have been increas.ngly utilized to perform highly complex s.rgical procedures. In fact, the robotic-as.is.ed approach to the treatment of many gynecological and urological s.rgical procedures.has.become the s.andard-of-care. The us. of robotic s.rgical s.s.em in thoracic s.rgery is.in its.early development. Video-as.is.ed thoracos.opic s.rgery （VATs. was.propelled forward in the early 1990＇s.without full appreciation for long-term cons.quences. increas.d cos. or therapeutic benefit. The trend in robotic-as.is.ed thoracic s.rgery is.projected to s.rpas. the adoption of VATs.and to mirror that of other robotic s.rgical s.bs.ecialties.

One-hundred years.have pas.ed s.nce the original des.ription of the commonly des.ribed phenomenon of pers.s.ent abdominal s.mptoms.being triggered by an acute enteric infection. This.firs. account was.generated out of as.ute obs.rvations.by s.r Arthur Hurs. in World War I. Additional des.riptions.followed from military and non-military practitioners.adding the evidence which has.trans.tioned this.recognized condition from as.ociation to caus.tion. While mechanis.ic unders.anding is.an area of active purs.it, this.his.orical accounting of a centuries.progres. highlights.important advances.and contributions.of military medicine and s.ientis.s.to advances.benefiting global populations.

The frugivorous.＂true＂ fruit fly, Bactrocera tryoni （Queens.and fruit fly）, is.pres.med to have a nonres.urced-bas.d lek mating s.s.em. This.is.largely untes.ed, and contrary data exis.s.to s.gges. Bactrocera tryoni may have a res.urce-bas.d mating s.s.em focus.d on fruiting hos. plants. We tes.ed the mating s.s.em ofBactrocera tryoni, and its.clos. s.bling Bactrocera neohumeralis. in large field cages.us.ng laboratory reared flies. We us.d obs.rvational experiments.that allowed us.to determine if：（i） mating pairs.were aggregated or nonaggregated; （ii） mating s.s.em was.res.urce or nonres.urce bas.d; （iii） flies.utilized pos.ible landmarks.（tall trees.over s.ort） as.mate-rendezvous.s.tes. and （iv） males.called females.from male-dominated leks. We recorded nearly 250 Bactrocera tryoni mating pairs.acros. all experiments. revealing that：（i） mating pairs.were aggregated; （ii） mating nearly always.occurred in tall trees.over s.ort; （iii） mating was.nonres.urce bas.d; and （iv） that males.and females.arrived at the mate-rendezvous.s.te together with no evidence that males.preceded females. Bactrocera neohumeralis.copulations.were much more infrequent （only 30 mating pairs.in total）, but for thos. pairs.there was.a s.milar preference for tall trees.and no evidence of a res.urce-bas.d mating s.s.em. s.me as.ects.of Bactrocera tryoni mating behavior align with theoretical expectations.of a lekking s.s.em, but others.do not. Until evidence for unequivocal female choice can be provided （as.predicted under a true lek）, the mating s.s.em ofBactrocera tryoni is.bes. des.ribed as.a nonres.urce bas.d, aggregation s.s.em for which we als. have evidence that land-marking may be involved.

Cultured beef is.a method where s.em cells.from s.eletal mus.le of cows.are cultured in vitro to gain edible mus.le tis.ue. For large-s.ale production of cultured beef, the culture technique needs.to become more efficient than today＇s.2-dimens.onal（2D） s.andard technique that was.us.d to make the firs. cultured hamburger. Options.for efficient large-s.ale production of s.em cells.are to culture cells.on microcarriers. either in s.s.ens.on or in a packed bed bioreactor, or to culture aggregated cells.in s.s.ens.on. We dis.us. the pros.and cons.of thes. s.s.ems.as.well as.the pos.ibilities.to us. the s.s.ems.for tis.ue culture. Either of the production s.s.ems.needs.to be optimized to achieve an efficient production of cultured beef. It is.anticipated that the optimization of large-s.ale cell culture as.performed for other s.em cells.can be trans.ated into s.cces.ful protocols.for bovine s.tellite cells.res.lting in res.urce and cos. efficient cultured beef.

In clas.ic community detection, it is.as.umed that communities.are exclus.ve, in the s.ns. of either s.ft clus.ering or hard clus.ering. It has.come to attention in the recent literature that many real-world problems.violate this.as.umption, and thus.overlapping community detection has.become a hot res.arch topic. The exis.ing work on this.topic us.s.either content or link information, but not both of them. In this.paper, we deal with the is.ue of overlapping community detection by combining content and link information. We develop an effective s.lution called s.bgraph overlapping clus.ering (s.C) and evaluate this.new approach in comparis.n with s.veral peer methods.in the literature that us. either content or link information. The evaluations.demons.rate the effectivenes. and promis. of s.C in dealing with large s.ale real datas.ts.

Vas.ular injury or interruption may play a role in vertebrate limb teratogenes.s. s.nce 5fluoro- 2'- deoxyuridine (FdU) can caus. vas.ular injury in the murine limb and s.ull prior to the appearance of s.eletal malformations.in thes. s.ructures. we s.udied the effects.of this.chemical on s.eletal development in the chick embryo and noted any vas.ular injury. The yolk s.cs.of day three ehick embryos.(Hamburger and Hamilton s.ates.17-19) were injected with s.lutions.of vary concentrations.of FdU in s.line. The embryos.developed until the 10th day of incubation when they were fixed for s.udy. Uninjected, s.line injected, and s.am injected control embryo were s.milarly fixed. Upon gros. ins.ection, frequent diffus. and s.ccular hernatomas. as.well as.fluid-filled blis.ers. were noted in the limbs.of embryos.treated with FdU.
