A nruj me ntsis monotonic muaj nuj nqi yog txhaj , txij li qhov xwm txheej no x1 < x2 implies uas f(x1) < f(x2) (yog f nce) lossis f(x1) > f(x2) (yog f txo).
Puas yog monotonic ua haujlwm bijective?
Strictly Monotone Real Function is Bijective.
Yuav ua li cas tsis yog monotonic ua haujlwm txhaj tshuaj?
Cov haujlwm monotonic no tuaj yeem tsis yog txhaj tshuaj. Yuav txhaj tshuaj muaj nuj nqi yuav tsum yog hom muaj zog ntawm monotony.
Yuav ua li cas txhaj tshuaj?
Hauv kev ua lej, ib qho kev txhaj tshuaj (tseem hu ua kev txhaj tshuaj, lossis ib-rau-ib txoj haujlwm) yog ua haujlwm f uas qhia cov ntsiab lus sib txawv rau cov ntsiab lus sib txawv ; uas yog, f(x1)=f(x2) implies x1=x 2Hauv lwm lo lus, txhua lub ntsiab lus ntawm lub luag haujlwm lub codomain yog cov duab ntawm feem ntau ntawm nws lub npe.
Puas monotonic ua haujlwm tas mus li?
Kev ua haujlwm uas ua kom txaus siab rau qee yam muaj zog monotonicity, thiab kwv yees cov txiaj ntsig nruab nrab, yog pointwise nruam. Tej monotone pointwise nruam muaj nuj nqi yog uniformly nruam. Kev ua haujlwm tsis tu ncua kuj tau txais.

Qhov twg tsis yog-insulin txhaj tshuaj yog txhaj ib zaug ib lub lim tiam?
FDA tau pom zoo txhaj tshuaj ib zaug ib lim piam Ozempic (semaglutide) rau kev siv rau hom 2 mob ntshav qab zib. Ozempic, tus GLP-1 agonist, tau pom qhov txo qis A1c tseem ceeb (ze li 2%!) nrog rau kev poob phaus hauv kev sim tshuaj . Yuav txhaj tshuaj ntshav qab zib li cas rau ib lub lis piam?
Puas yog exponential muaj nuj nqi txuas ntxiv?
Yog li nco ntsoov txhua lub zog ua haujlwm yog txuas ntxiv. Tom qab ntawd tag nrho cov exponential functions yog nruam piv txwv f ntawm x sib npaug 3 rau x g ntawm x sib npaug 10 rau x, h ntawm x sib npaug e rau x. Tag nrho cov haujlwm no tag nrho cov exponential functions yog txuas mus rau txhua qhov chaw .
Dab tsi yog qhov tshuaj txhaj tshuaj tiv thaiv qib siab?
(1) Feem ntau. Lo lus "kev tsim nyog cov nqi txhaj tshuaj tertiary" txhais tau tias txhua tus nqi them lossis tshwm sim (txawm tias tsis them nyiaj rau tus as-qhauj) rau ib qho tshuaj txhaj tshuaj tertiary (tshwj tsis yog cov tshuaj hydrocarbon uas rov qab tau) uas yog siv.
Puas yog tshuaj aspirin inhibits platelet muaj nuj nqi?
Cov tshuaj tiv thaiv kab mob ntawm cov tshuaj aspirin (acetylsalicylic acid) yog vim inhibition ntawm platelet muaj nuj nqi los ntawm acetylation ntawm platelet cyclooxygenase (COX) ntawm lub luag haujlwm tseem ceeb amino acid serine529 . Yuav ua li cas yog cov tshuaj aspirin ntawm platelet muaj nuj nqi?
Kuv puas tuaj yeem muaj covid yog tias kuv txhaj tshuaj tiv thaiv?
Cov neeg feem coob uas tau txais COVID-19 yog tsis tau txhaj tshuaj. Txawm li cas los xij, txij li cov tshuaj tiv thaiv tsis tau zoo 100% tiv thaiv kab mob, qee cov neeg uas tau txhaj tshuaj tag nrho tseem yuav tau txais COVID-19 . Kuv yuav tsum tau kuaj tus kab mob COVID-19 sai npaum li cas yog tias txhaj tshuaj tiv thaiv?
