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.

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.
