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.

Immunizat.on wit. adjuvant.plus ant.gen induces durable t.cell immunit. and is a mainst.y of vaccines. Here, t.e consequence of separat.ng ant.gen st.mulat.on of t.cells from t.e adjuvant.response was st.died in a re-t.ansfer model. Effect.r CD8 t.cells in recipient.mice were exposed t. lipopolysaccharide （LPS）, t.e t.ll-like recept.r 4 （t.R4） ligand, which significant.y increased persist.nce. While accumulat.on in lymphoid and non-lymphoid organs was evident. t.is result.depended upon t.e t.ming of LPS administ.at.on and t.e presence of t.e t.R4 adapt.r t.IF in t.e recipient.mice. Int.rest.ngly, t.ere was very lit.le impact.of t.e LPS response on subset.different.at.on, which rat.er appeared t. be programmed by ant.gen and cost.mulat.on. t. discern fact.rs t.at.limit.accumulat.on, int.rleukin 10 （IL-IO） was t.rget.d since it.is a product.of t.R4 t.iggering and mit.gat.s inflammat.on. Blockade of IL-IO increased accumulat.on even t.ough t.e effect.r CD8 t.cells were well past.t.e priming phase, but.upon recall int.rferon-y secret.on was not.affect.d as would be expect.d when IL-IO is present.during priming. t.us, t.e adjuvant.alt.red microenvironment.is effect.ve not.only in t.e presence of ant.gen but.also during a window of effect.r CD8 t.cell st.sis, suggest.ng t.at.pat.ogen-associat.d molecular pat.ern molecules released during co-infect.on, ot.by vaccines, could alt.r t.e survival fat. of specific effect.r t.cells.

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.

A new numerical approach based on a mult.block, mult.grid, local refinement.met.od has been developed. t.e mult.block st.uct.re makes grid generat.on for complex geomet.ies easier,mult.grid t.chniques significant.y accelerat. t.e rat. of convergence and t.e local refinement.met.od provides high spat.al resolut.on of boundary lay6r and separat.d vort.cal flows wit. much reduced comput.r memory and CPU t.me. Sample t.ree-dimensional flow comput.t.ons for complex geomet.ies are present.d t. illust.at. t.e advant.ges in t.rm of memory savings and reduct.ons of CPU t.me in obt.ining high spat.al resolut.on solut.ons. High spat.al resolut.on in t.e inner viscous layer is achieved by using t.e values of y+ for t.e first.grid cent.rs rom t.e wall in t.e order of 1 t. 7. t.e required solut.on resolut.on in t.e dominant.y viscous flow region (boundary layer, vort.x core, or t.ree-dimensional separat.d zone) dict.t.s t.e accept.ble spacing of grid cells in t.at.region. It.is very desirable t. be able t. reduce grid spacing locally in t.e crit.cal region wit.out.changing t.e overall grid. t.e local refinement.t.chnique doubles grid numbers in all t.ree direct.ons for every level of refinement. Mult.ple levels of local grid refinement.wit. moderat. grid st.et.hing can be used t. provide fine grid spacing in rapidly changing flow regions such as near t.e wall, vort.x core and separat.d shear layer. t.us, t.e met.od provides t.e required fine spat.al resolut.on in t.e dominant.y viscous region which is relat.vely small compared t. t.e ent.re comput.t.onal domain. t.is also avoids t.e used of excessively large aspect.rat.os of t.e grid cells near t.e rapidly changing now regions t.us reduces t.uncat.on error and improves robust.ess. Furt.ermore, t.e result. of numerical experiment.t.on indicat. t.at.t.e present.mult.grid local refinement.t.chnique provides very effect.ve numerical communicat.ons across t.e fine and coarse grid int.rfaces because t.e finer mesh is embedde
