We know that our Uni.erse i. composed of only - 4.5% ＂known＂ matter; therefore, our understandi.g i. i.complete. Thi. can be seen di.ectly i. the case of neutri.o osci.lati.ns （wi.hout even consi.eri.g potenti.l other uni.erses）. Charm quarks have had consi.erable i.pact on our under- standi.g of known matter, and quantum chromodynami.s （QCD） i. the only local quantum fi.ld theory to descri.e strong forces. i. i. possi.le to learn novel lessons concerni.g strong dynami.s by measuri.g rates around the thresholds of [Q^-Q] states wi.h Q = b, c. Furthermore, these states provi.e us wi.h gateways towards new dynami.s （ND）, where we must transi.i.n from ＂accuracy＂ to ＂preci.i.n＂ eras. Fi.ally, we can make connecti.ns wi.h τ transi.i.ns and, perhaps, wi.h dark matter. Charm dynami.s acts as a bri.ge between the worlds of li.ht- and heavy-flavor hadrons （namely, beauty hadrons）, and fi.di.g regi.nal asymmetri.s i. many-body fi.al states may prove to be a ＂game changer＂. There are several di.ferent approaches to achi.vi.g these goals： for exam- ple, experi.ents such as the Super Tau-Charm Factory, Super Beauty Factory, and the Super Z~ Factory act as gatekeepers - and deeper thi.ki.g regardi.g symmetri.s.

H. pylori.was detected i. 63.2% of samples by PCR. The vacA gene was present i. 84.6% of cases, cagA i. 58.2%, and i.eA1 i. 29.7%. Among vacA vari.nts, s1 allele was most common (53.2%), followed by m1 (42.9%), m2 (37.7%), and s2 (13%) alleles.

The thermal analysi. of the annular rectangular profi.e fi.s wi.h vari.ble thermal properti.s i. i.vesti.ated by usi.g the homotopy analysi. method （HAM）. The thermal conducti.i.y and heat transfer coeffi.i.nt are assumed to vary wi.h a li.ear and power-law functi.n of temperature, respecti.ely. The effects of the thermal-geometri. fi. parameter and the thermal conducti.i.y parameter vari.ti.ns on the temperature di.tri.uti.n and fi. effi.i.ncy are i.vesti.ated for di.ferent heat transfer modes. Results from the HAM are compared wi.h numeri.al results of the fi.i.e di.ference method （FDM）. i. can be seen that the vari.ti.n of di.ensi.nless parameters has a si.ni.i.ant effect on the temperature di.tri.uti.n and fi. effi.i.ncy.
