چکیده
We separate many of the basic fragments of classical logic which are used in reverse constructive mathematics. A group of related Kripke and topological models is used to show that various fragments of the Weak Law of the Excluded Middle, the Limited Principle of Omniscience, and Markov’s Principle, including Weak Markov’s Principle, do not imply each other. §

Separating Fragments of Wlem, LPO, and MP
We separate many of the basic fragments of classical logic which are used in constructive reverse mathematics. A group of related Kripke and topological models is used to show that various fragments of the Weak Law of the Excluded Middle, the Limited Principle of Omniscience, and Markov’s Principle, including Weak Markov’s Principle, do not imply each other.
متن کاملResonance Raman spectroscopy reveals pH-dependent active site structural changes of lactoperoxidase compound 0 and its ferryl heme O-O bond cleavage products.
The first step in the enzymatic cycle of mammalian peroxidases, including lactoperoxidase (LPO), is binding of hydrogen peroxide to the ferric resting state to form a ferric-hydroperoxo intermediate designated as Compound 0, the residual proton temporarily associating with the distal pocket His109 residue. Upon delivery of this "stored" proton to the hydroperoxo fragment, it rapidly undergoes O...
متن کاملTwo-dimensional conformation-dependent electrophoresis (2D-CDE) to separate DNA fragments containing unmatched bulge from complex DNA samples.
DNA fragments containing mispaired and modified bases, bulges, lesions and specific sequences have altered conformation. Methods for separating complex samples of DNA fragments based on conformation but independent of length have many applications, including (i) separation of mismatched or unmatched DNA fragments from those perfectly matched; (ii) simultaneous, diagnostic, mismatch scanning of ...
متن کاملLactoperoxidase and human airway host defense.
The lactoperoxidase (LPO) antibiotic system is a well-characterized component of mammary and salivary gland secretions. Because LPO has been shown to function in ovine airways, human airway tissue and secretions were examined for the presence of LPO and its substrate, the anion thiocyanate (SCN-). In addition, human airway secretions were tested for LPO-mediated antibacterial activity, and LPO'...
متن کاملH2O2-mediated cross-linking between lactoperoxidase and myoglobin: elucidation of protein-protein radical transfer reactions.
The H(2)O(2)-dependent reaction of lactoperoxidase (LPO) with sperm whale myoglobin (SwMb) or horse myoglobin (HoMb) produces LPO-Mb cross-linked species, in addition to LPO and SwMb homodimers. The HoMb products are a LPO(HoMb) dimer and LPO(HoMb)(2) trimer. Dityrosine cross-links are shown by their fluorescence to be present in the oligomeric products. Addition of H(2)O(2) to myoglobin (Mb), ...
