This paper is a first step in constructing the category of braided sets and its closest relative, Yang–Baxter sets. Our main emphasis on construction morphisms extensions problem important for possible constructions new solutions equation braid equation. result description family $$B \otimes C$$ \times , given two linear (set-theoretic) $$(B, R^B)$$ $$(C, R^C)$$

the synthesis and single-crystal x-ray structure determination of the title compound [(bipy) , pb(0 ,cme) (o clo )] (1) and [(bipy) pb(clo ) ] (2) is described. compound (i) crystallizes in the triclinic space group p1(2), a= 7.384(2), b= 12.824(3), c= 10.622(6) a, ?= 73.41(2), ?= 80.98(2), ?= 73.68(2)', z= 2, and r =0.033 for 3408 independent reflections .compound (2) crystallizes in the ...

objective(s) curative treatment of breast cancer patients using chemotherapy often fails as a result of intrinsic or acquired resistance of the tumor to the drug. erk is one of the main components of the ras/raf/mek/erk cascade, which mediates signal from cell surface receptors to transcription factors to regulate different gene expression. in this study, cytotoxicity and the expression of erk1...

For bounded non-negative operators A and B, Furuta showed 0 ≤ A ≤ B implies A r 2BA r 2 ≤ (A r 2BA r 2 ) s+r t+r (0 ≤ r, 0 ≤ s ≤ t). We will extend this as follows: 0 ≤ A ≤ B ! λ C (0 < λ < 1) implies A r 2 (λB + (1− λ)C)A r 2 ≤ {A r 2 (λB + (1 − λ)C)A r 2 } s+r t+r , where B ! λ C is a harmonic mean of B and C. The idea of the proof comes from Jensen’s inequality for an operator convex functio...

this study examines changes in the urinary 1-hydroxypyrene (1-ohp) concentration as a polycyclic aromatic hydrocarbon (pah) metabolite related to smoking among eight volunteers. the study subjects consisted of 8 participants (2 smokers, 4 ex-smokers and 2 non-smokers; mean age 23, range 21 ~ 24 years old) in a smoking cessation program. three urine samples were collected each week for 4 weeks f...
