Liveine tsa maiketsetso, bohlale ba maiketsetso bo ka pepesa bomenemene

Makasine Khokahano Khemistri e hatisitse liphetho tsa tlhahlobo ea lik'hemik'hale tsa veine e khubelu.

Liunivesithi tsa Geneva le Bordeaux li khonne ho tseba, ka nepo ea 100%, leibole ea lik'hemik'hale tsa veine e khubelu ea lik'hamphani tse supileng tse kholo tse hlahisang veine sebakeng sa Bordeaux.

Liphetho li ile tsa fumanoa ka lebaka la tšebeliso ea Artificial Intelligence.

Ho loants'a veine ea maiketsetso

Liphetho tsena, tse hatisitsoeng koranteng ea 'Communications Chemistry', li bula tsela bakeng sa lisebelisoa tse ncha tse ka bang teng ho loants'a boqhetseke veine, le lisebelisoa tsa ho bolela esale pele ho tataisa ho etsa liqeto lekaleng la veine. 

Veine e 'ngoe le e 'ngoe e entsoe ka motsoako o motle le o rarahaneng oa limolek'hule tse likete. Maemo a tsona a feto-fetoha ho latela sebopeho sa morara, ho ipapisitse le sebopeho, sebopeho sa mobu, mefuta e fapaneng ea morara le litloaelo tsa moetsi oa veine. Phapang ena, leha e le nyane, e ka ba le tšusumetso e kholo tatsong ea veine. Ka liphetoho tsa boemo ba leholimo, litloaelo tse ncha tsa bareki le keketseho ea tlhahiso ea veine ea maiketsetso, tlhokahalo ea ho ba le lisebelisoa tse sebetsang tsa ho tseba hore na veine ke efe e se e le bohlokoa haholo.

Chromatography ea khase

E 'ngoe ea mekhoa e sebelisoang ke 'gas chromatography'., e kenyeletsang ho arola likarolo tsa motsoako ka kamano pakeng tsa lisebelisoa tse peli. Mokhoa ona, ka ho khetheha, o hloka hore motsoako o fete ka har'a tube e tšesaane haholo e bolelele ba limithara tse 30, mona likarolo tse nang le kamano e kholo le thepa ea tube li tla arohana butle-butle ho tse ling; Karohano e 'ngoe le e' ngoe e tla ngoloa ke 'mass spectrometer', e tla hlahisa chromatogram, e khonang ho lemoha 'lihloro' tse ka tlas'a likarohano tsa limolek'hule.

Tabeng ea veine, ka lebaka la limolek'hule tse ngata tse e qapang, litlhōrō tsena li ngata haholo, e leng se etsang hore tlhahlobo e feletseng le e feletseng e be thata haholo. Ka tšebelisano 'moho le sehlopha sa Stephanie Marchand, ho tsoa Setsing sa Saense ea Morara le Veine ea Univesithi ea Bordeaux, sehlopha sa lipatlisiso sa Alexandre Pouget se fumane tharollo ea bothata bona, se kopanyang li-chromatogram le lisebelisoa tsa bohlale tsa maiketsetso.

Chromatograms le Artificial Intelligence

Li-chromatogram li tsoa ho veine e khubelu e 80 ho tloha ho li-vintage tse leshome le metso e 'meli, pakeng tsa 1990 le 2007., le libaka tse supileng sebakeng sa Bordeaux. Lintlha tsena tse tala li ile tsa sebetsoa ka ho sebelisa mochine oa ho ithuta, sebaka sabohlale ba maiketsetso moo li-algorithms li ithutang ho khetholla mekhoa e iphetang ka lihlopha tsa tlhahisoleseling. Mokhoa ona o re lumella ho ela hloko li-chromatogram tse felletseng tsa veine e 'ngoe le e' ngoe, e ka kenyelletsang lintlha tse fihlang ho 30.000, le ho akaretsa chromatogram e 'ngoe le e' ngoe ka likhokahanyo tse peli X le Y, ts'ebetso ena e bitsoa phokotso ea boholo.

Ka ho beha likhokahano tse ncha kerafong, bafuputsi ba ile ba khona ho bona 'maru' a supileng a lintlha mme ba fumana hore e 'ngoe le e' ngoe ea tsena e ne e bokella li-vintage tsa thepa e le 'ngoe ho ipapisitse le ho tšoana ha bona ka lik'hemik'hale. Ka tsela ena bafuputsi ba ile ba khona ho bontša hore k'hamphani ka 'ngoe e na le tekeno ea eona ea lik'hemik'hale.

Nakong ea litlhahlobo tsa bona, bafuputsi ba ile ba fumana seo boitsebiso ba lik'hemik'hale tsa veine tsena e ne e se defie hlohlelletsoa ke ho kopana ha limolek'hule tse itseng, empa ho tsoa ho lik'hemik'hale tse pharaletseng. "Liphetho tsa rona li bonts'a hore hoa khoneha ho tseba tšimoloho ea veine e nepahetseng ea 100%, ka ho sebelisa mekhoa ea phokotso ea li-dimensionality ho li-chromatogram tsa khase - Pouget, eo hape a etelletseng lipatlisiso pele - thuto e fana ka tsebo e ncha mabapi le likarolo tsa boitsebahatso. kutlo dintho tsa veine. E boetse e bula tsela bakeng sa nts'etsopele ea lisebelisoa tsa ho ts'ehetsa ts'ebetso ea ho etsa liqeto, joalo ka ho boloka boitsebahatso le ponahatso ea sebaka, le ho loants'a maqheka a maiketsetso."
