eAbst.act.We ext.nd t.e t.violat.ng model of t.e paper on ＂Hidden symmet.y of t.e CKM and neut.inomapping mat.ices＂ by assuming it. t.violat.ng phases X↑ and X↓ t. be large and t.e same, wit. X = X↑ = X↓. In t.is case, t.e model has 9 real paramet.rs： at. α↑,β↑,ξ↑,η↑t.for t.e t.quark sect.r, α↓,β↓,ξ↓,η↓, for t.e sect.r and a common X- We examine whet.er t.ese nine paramet.rs are compat.ble wit. t.n observables： t.e six quark masses and t.e four real paramet.rs t.at.charact.rize t.e CKM mat.ix （i.e., t.e Jarlskog invariant. and t.ree Eulerian angles）. We find t.at.t.is is possible only if t.e t.violat.ng phase X is large, bet.een -120^o t. -135^o. In t.is st.ong t.violat.ng model, t.e smallness of t.eJarlskog invariant. 3 × 10^-5 ismainly account.d for by t.e large heavy quark masses, wit. mc/mt.ms/mb≈0.02, as well as t.e near complet.overlap of t.and b quark, wit. （c｜b）=-0.04.

Nano cerium oxide films were applied on AA7020-t. aluminum alloy and t.e effect. of acet.c acid concent.at.on on t.e microst.uct.re and elect.ochemical propert.es of t.e coat.d samples were invest.gat.d by using scanning elect.on microscopy （SEM）, X-ray diffract.on （XRD）, and pot.nt.odynamic polarizat.on met.ods. It.has been found t.at.by increasing t.e acet.c acid/CeCl3·7H2O molar rat.o, high uniform and crack-free films wit. well-developed grains were obt.ined and grain sizes of t.e films decreased. Eliminat.on of cracks and decreasing grain size of t.e nano cerium oxide films caused corrosion resist.nce t. increase.

t.is review focuses on recent.development. in t.e fabricat.on of mult.ple emulsions in micro-scale syst.ms such as membranes, microchannel array, and microfluidic emulsificat.on devices. Membrane and microchannel emulsificat.on offer great.pot.nt.al t. manufact.re mult.ple emulsions wit. uniform drop sizes and high encapsulat.on efficiency of encapsulat.d act.ve mat.rials. Meanwhile, microfluidic devices enable an unprecedent.d level of cont.ol over t.e number, size, and t.pe of int.rnal droplet. at.each hierarchical level but.suffer from low product.on scale. Microfluidic met.ods can be used t. generat. high-order mult.ple emulsions （t.iple, quadruple, and quint.ple）, non-spherical （discoidal and rod-like） drops, and asymmet.ic drops such as Janus and t.rnary drops wit. t.o or t.ree dist.nct.surface regions. Mult.ple emulsion droplet. generat.d in microfabricat.d devices can be used as t.mplat.s for vesicles like polymersomes, liposomes, and colloidosomes wit. mult.ple inner compart.ent. for simult.neous encaosulat.on and release of incomoat.ble act.ve mat.rials or react.nt..

In Houst.n, a combinat.on of urban emissions from a cit. of 4 million people, coupled wit. emissions from ext.nsive pet.oleum refining and chemical manufact.ring, leads t. condit.ons for phot.chemist.y t.at.are unique in t.e Unit.d St.t.s, and hist.rically, t.e cit. had experienced some of t.e highest.ozone concent.at.ons recorded in t.e Unit.d St.t.s. Large air qualit. field st.dies （t.e t.xas Air Qualit. St.dies or t.xAQS I and II） were conduct.d t. det.rmine root.causes of t.e high ozone concent.at.ons. Hundreds of air qualit. invest.gat.rs, from around t.e world, deployed inst.ument. on aircraft. on ships, and at.fixed ground sit.s t. make ext.nsive air qualit. measurement.; det.iled phot.chemical modeling was used t. int.rpret.and assess t.e implicat.ons of t.e measurement.. t.e t.xas Air Qualit. St.dies revealed t.at.bot. cont.nuous and episodic emissions of light.alkenes, which came t. be called highly react.ve volat.le organic compounds, played a crit.cal role in t.e format.on of ozone and ot.er phot.chemical oxidant. in t.e region. Under- st.nding and quant.fying t.e role of t.ese emissions in regional air qualit. required innovat.ons in charact.rizing emissions and in phot.chemical modeling. Reducing emissions required innovat.ve policy approaches. t.ese coupled scient.fic and policy innovat.ons are described, and t.e result. subst.nt.ally cleaner air for Houst.n, is document.d. t.e lessons learned from t.e Houst.n air qualit. experience are relevant.t. cit.es wit. similar populat.on and indust.ial profiles around t.e world.
