In order to study the effects of chemical modifications of the vinyl groups of heme on oxygen and carbon monoxide binding to myoglobin, apomyoglobins from horse heart were reconstituted with six different hemins with various side chains. Laser flash photolysis experiments of these reconstituted myoglobins showed that the combination rate constants for oxygen (k') and carbon monoxide (l') were c...

The effect of cation size on the rate and energy of electron transfer to [(M(+))(acceptor)] ion pairs is addressed by assigning key physicochemical properties (reactivity, relative energy, structure, and size) to an isoelectronic series of well-defined M(+)-acceptor pairs, M(+) = Li(+), Na(+), K(+). A 1e(-) acceptor anion, alpha-SiV(V)W(11)O(40)(5-) (1, a polyoxometalate of the Keggin structura...

Let K, D be convex centrally symmetric bodies in R. Let k < n and let dk(K, D) be the smallest Banach–Mazur distance between k-dimensional sections of K and D. Define ∆(k, n) = sup dk(K, D), where the supremum is taken over all n−dimensional convex symmetric bodies K, D. We prove that for any k < n ∆(k, n) ∼log n {√ k if k ≤ n k2 n if k > n , where A ∼log n B means that 1/(C log n) ·A ≤ B ≤ (C ...

An essential problem in music information retrieval is to determine the similarity between two given melodies; there are several melodic similarity measures that have been proposed, among others, the Mongeau-Sankoff measure. In this work we implemented a modified version of the Mongeau-Sankoff measure. We conducted an experimental study to compare the implemented measure with other similarity m...

It is well known that, when normalized by n, the expected length of a longest common subsequence of d sequences of length n over an alphabet of size σ converges to a constant γσ,d. We disprove a speculation by Steele regarding a possible relation between γ2,d and γ2,2. In order to do that we also obtain some new lower bounds for γσ,d, when both σ and d are small integers.

Foundations of Artiicial Intelligence presents a number of chapters from major players in artiicial intelligence (AI) that discuss fundamental assumptions underlying the dominant approaches to AI today. Perhaps the best parts of the book are the critiques: each chapter is followed by an in-depth critique that evaluates the utility of those assumptions in pursuing the goal of AI. But what is the...

We review the status of the leptonic decay constants f K and f ,⊥ K of the K and K * , respectively , and the SU(3) breaking quantities a 1 (K) and a ,⊥ 1 (K *), the first Gegenbauer-moments of the leading-twist distribution amplitudes of K and K *. We obtain new predictions from QCD sum rules which are relevant for the calculation of K and K * form factors, for instance T B→K * 1 , which deter...

Deterministic mathematical models of biochemical processes operate as if the empirically derived rate constants governing the dynamics are known with certainty. Our objective in this study was to explore the sensitivity of a deterministic model of blood coagulation to variations in the values of its 44 rate constants. This was accomplished for each rate constant at a given time by defining a no...

Let L/[0, k&1]. A family F is called an (n, k, L)-system (or (k, L)system, L-system for short) if F/( [n] k ) and |F & F$| # L holds for all distinct F, F$ # F. Define m(n, k, L) :=max[ |F | : F is (n, k, L)-system]. If there exist constants c, c$, : depending only on k and L, and satisfying cn<m(n, k, L)<c$n, then we define :(k, L) :=: which is called the exponent of (k, L)-system. Conjecture ...

Basing on the DFT calculations we propose new theoretical model which describes both surface tension σ of short chain n-alkanes at their normal boiling points and reaction rate constants with hydroxyl radicals OH• (at 297 ± 2 K) basis molecular orbital electronic characteristics. It has been shown that intermolecular dispersion attraction within liquid monolayer these compounds, as well k are d...
