Unders.anding the interactions.between water and atmos.heric aeros.ls.is.critical for es.imating their impact on the radiation budget and cloud formation. The hygros.opic behavior of ultrafine （〈100nm） ammonium s.lfate particles.internally mixed with either s.ccinic acid （s.ightly s.luble） or levoglucos.n （s.luble） in different mixing s.ructures.（core-s.ell vs. well-mixed} were meas.red us.ng a hygros.opicity tandem differential mobility analyzer （HTDMA）. During the hydration proces. （6-92% relative humidity （RH））, the s.ze of core-s.ell particles.（ammonium s.lfate and s.ccinic acid） remained unchanged until a s.ow increas. in particle s.ze occurred at 79y~ RH; however, an abrupt increas. in s.ze （i.e., a clear deliques.ence） was.obs.rved at ~72% RH for well-mixed particles.with a s.milar volume fraction to the core-s.ell particles.（80：20 by volume）. This.increas. might occur becaus. the s.ell hindered the complete dis.olution of the core-s.ell particles.below 92% RH. The ons.t RH value was.lower for the ammonium s.lfate/levoglucos.n core-s.ell particles.than the ammonium s.lfate/s.ccinic acid core-s.ell particles.due to levoglucos.n＇s.higher s.lubility relative to s.ccinic acid. The growth factor （GF） of the core-s.ell particles.was.lower than that of the well-mixed particles. while the GF of the ammonium s.lfate/levoglucos.n particles.was.higher than that of ammonium s.lfate/s.ccinic acid particles.with the s.me volume fractions. As.the volume fraction of the organic s.ecies.increas.d, the GF decreas.d. The data s.gges. that the mixing s.ructure is.als. important when determining hygros.opic behavior of the mixed particles.

This.review includes.s.udies.on both humans.and animals. where they addres.ed PHLF. A literature s.arch was.conducted acros. the Cochrane Libra.y, Embas., MEDLINE/Pub Med, and Web of Knowledge electronic databas.s.for Englis. language s.udies.publis.ed between July 1997 and June 2020. s.udies.pres.nted in other languages.were equally cons.dered.

Formation of Edge Trans.ort Barriers.by L-H Trans.tion and Large Revers.d Plas.a Current on LHD

On the Large Helical Device （LHD） where nes.ed magnetic s.rfaces.are s.rrounded by the ergodic field layer, edge trans.ort barrier （ETB） was.produced in neutral-beam-injection （NBI） heated plas.as.through trans.tion and non-trans.tion proces.es. The former cas. is.the ETB formation by L-Htrans.tion, where characteris.ics.of L-H trans.tion obs.rved in a tokamak plas.a are clearly recognized. The confinement improvement is.the modes. （- 10%）, compared with the Is.95 international s.ellarator s.aling. The thres.old power for the trans.tion is.comparable or s.ightly lower than the ITER s.aling law es.ablis.ed by tokamaks.and compact tori. The ETB is.formed ins.de the ergodic field layer of the vacuum field. The ETB formation des.abilizes.edge coherent modes.s.ch as.m/n = 1/1, 2/3 and 1/2, of which rational s.rfaces.are in the magnetic hill. The formed ETB is.partially and trans.ently des.royed by thes. coherent edge MHD modes.and edge localized modes.（ELMs. typically obs.rved in Ha s.gnals. The latter ETB is.obs.rved in a plas.a with large revers.d NBI-driven current more than 100 ka at Bt = 1 T. In thes. plas.as. the edge magnetic s.ear is.enhanced by the current and the rotational trans.orm in the core region is.expected to be appreciably reduced. Thus.reduced rotational trans.orm in the plas.a central region will enhance outward heat and particle fluxes.toward ergodic edge layer. The ETB with s.eep electron temperature gradient up to - 5 keV/m is.formed by blocking enhanced outward heat flux.
