Root-to-shoot signaling is use. by plants to coordinate.shoot de.e.opme.t with the.conditions e.pe.ie.ce. by the.roots. A mobile.and biologically active.compound, the.bps signal, is ove.-produce. in roots of an Arabidopsis thaliana mutant calle. bypass1 （bpsl）, and might also be.a normally produce. signaling mole.ule.in wild-type.plants. Our goal is to ide.tify the.bps signal che.ically, which will the. allow us to asse.s its production in normal plants. To ide.tify any signaling mole.ule. a bioassay is re.uire., and he.e.we.de.cribe.the.de.e.opme.t of a robust, simple. and quantitative.bioassay for the.bps signal. The.de.e.ope. bioassay follows the.growth-re.ucing activity of the.bps signal using the.pCYCB1;I：：GUS ce.l cycle.marke.. Wild-type.plants carrying this marke., and provide. the.bps signal through e.the. grafts or me.abolite.e.tracts, showe. re.uce. ce.l division. By contrast, control grafts and tre.tme.t with control e.tracts showe. no change.in pCYCB1;I：：GUS e.pre.sion. To de.e.mine.the.che.ical nature.of the.bps signal, e.tracts we.e.tre.te. with RNase.A, Prote.nase.K, or he.t. None.of the.e.tre.tme.ts diminishe. the.activity of bpsl e.tracts, sug- ge.ting that the.active.mole.ule.might be.a me.abolite. This bioassay will be.use.ul for future.bioche.ical fractionation and analysis dire.te. toward bps signal ide.tification.

Atmosphe.ic variable.(te.pe.ature. ve.ocity, e.c.) are.ofte. de.ompose. into balance. and unbalance. compone.ts that re.re.e.t low-fre.ue.cy and high-fre.ue.cy wave., re.pe.tive.y. Such de.ompositions can be.de.ine., for instance. in te.ms of e.ge.mode. of a line.r ope.ator. Traditionally the.e.de.ompositions ignore.phase.change. of wate. since.phase.change. cre.te.a pie.e.ise.line.r ope.ator that diffe.s in diffe.e.t phase.(cloudy ve.sus non-cloudy). He.e.we.inve.tigate.the.following que.tion: How can a balance.–unbalance. de.omposition be.pe.forme. in the.pre.e.ce.of phase.change.? A me.hod is de.cribe. he.e.motivate. by the.case.of small Froude.and Rossby numbe.s,in which case.the.asymptotic limit yie.ds pre.ipitating quasi-ge.strophic e.uations with phase.change.. Facilitate. by its ze.o-fre.ue.cy e.ge.value. the.balance. compone.t can be.found by pote.tial vorticity(PV) inve.sion, by solving an e.liptic partial diffe.e.tial e.uation(PDe., which include. He.viside.discontinuitie. due.to phase.change.. The.me.hod is also compare. with two simple. me.hods: one.which ne.le.ts phase.change., and one.which simply tre.ts the.raw pre.sure.data as a stre.mfunction. Te.ts are.shown for both synthe.ic, ide.lize. data and data from We.the. Re.e.rch and Fore.asting(WRF) mode. simulations. In comparisons, the.phase.change.me.hod and no-phase.change.me.hod produce.substantial diffe.e.ce. within cloudy re.ions, of approximate.y 5K in pote.tial te.pe.ature. due.to the.pre.e.ce.of clouds and phase.change. in the.data. A the.re.ical justification is also de.ive. in the.form of a e.liptic PDe.for the.diffe.e.ce. in the.two stre.mfunctions.

The.ability to sme.l is important for prote.tion from dange. and quality of life. e.e. in childre.. Although sme.l loss is rare.in childre., it can be.indicative.of some.childhood dis-orde.s and may be.use.ul for unde.standing some.disorde.s. This pape. re.ie.s the.me.hods and re.ults of be.avioral te.ting olfaction in childre., with an e.phasis on odor ide.tification, the.most common me.hod of asse.sing the.se.se.of sme.l in both childre. and adults. The.Pe.diatric Sme.l Whe.l? is de.cribe. as a re.ative.y ne. and powe.ful tool for te.ting olfaction in childre. as young as 4 ye.rs of age. An e.ample.of its use.in te.ting childre. with a childhood disorde.s (autism spe.trum disorde., ASD) is provide. in addition to a re.ie. of the.lite.ature.on sme.l function in ASD.
