We discuss the two-loop integrals necessary for evaluating massless 2 → 2 scattering amplitudes. As a test process, we consider the leading colour two-loop contribution to q ¯ q → q ′ ¯ q ′. We show that for physical scattering processes the two Smirnov-Veretin planar box graphs I1 and I2 are accompanied by factors of 1/(D − 4) thereby necessitating a knowledge of both I1 and I2 to O(ǫ). Using ...

Molecular dynamics simulations, computational alanine scanning and sequence analysis were used to investigate the structural properties of the Galpha(i1)/GoLoco peptide complex. Using these methodologies, binding of the GoLoco motif peptide to the Galpha(i1) subunit was found to restrict the relative movement of the helical and catalytic domains in the Galpha(i1) subunit, which is in agreement ...

In the tunnel limit, the current-phase relation of Josephson junctions can be expanded as I(φ) = I1 sinφ + I2 sin 2φ. Standard BCS theory predicts that I1RN ∼ ∆/e and I2/I1 ∼ D, where RN is the resistance of the junction in the normal state, ∆ is the superconducting gap, and D ≪ 1 is the junction transparency. In the cuprates, the experimental value of I1RN (I2/I1) is much smaller (larger) than...

i=1 t i) k (87) We now comment on how the derivation changes when n = 2 and k 3. The case n 3 and k = 2 follows as well due to the symmetric functional equation (Equation 12). Note that up to Eq. 57 the derivation is valid when n = 2. Furthermore, note that the sum in Eq. 56 consists now of one term where l = j 1 = 1. Thus, Eq. 56 and Eq. 57 yield, using x i = z ij1 y j1 + z in y n (n=2, j 1 = ...

Apolipoproteins C-I1 (apoC-11) and C-111 (apoC-111) are distributed among all the major lipoprotein classes, particularly very low density (VLDL) and high density lipoproteins (HDL). We have determined concentrations of apoC-I1 and apoC-111 in VLDL and HDL in subjects with a wide range of VLDL triglyceride and HDL cholesterol levels, and correlated these levels with fractional catabolic rates (...

will mean the sum of the values f (i1, i2, ..., ik) over all ”good” k-tuples (i1, i2, ..., ik) ; hereby, a k-tuple (i1, i2, ..., ik) is called ”good” if it satisfies iu ∈ {1, 2, ..., n} for every u ∈ {1, 2, ..., k} and also satisfies all the assertions A1, A2, ..., Al. Using this notation, we can write many typical sums in a simpler form: For instance, ∑ 1≤i≤n f (i) = i ∑ f (i) , and ∑ 1≤i<j≤n ...

Human glomerular epithelial cells produce matrix material e.g. collagen type IV. In vitro, the synthesis of collagen can be monitored by the incorporation of 3H-proline, a precursor molecule of the collagens. We report on the enhancement of collagen synthesis by glomerular epithelial cells with highly purified or recombinant I1-1. Since I1-1 is released from monocytes or glomerular mesangial ce...

In this note we explain a point left unexplained in [7], namely that for a sufficiently smooth m-linear Calderón-Zygmund operator bounded on a product of Lebesgue spaces we have (1) T ( f1, . . . , fm) = ∑ i1 · · ·∑ im λ1,i1 · · ·λm,imT (a1,i1 , . . . ,am,im) a.e., where a j,i j are H p j atoms, λ j,i j ∈ C, and f j = ∑i j λ j,i j a j,i j are H p j distributions. In some particular cases the pr...

Figure 1: Matching I1 and I2 using DNN flow. Each column shows the matching of different levels. In first row, parallelogram denotes the DNN feature image of I1, where dot represents the feature at that location. Line with arrow denotes the flow vector of the corresponding feature, while curve with arrow denotes guidance from high level to low level. In second row, the color rectangles show I1’...

1. Nuclei were isolated from rat liver and spleen by a standard technique which preserved the nuclear membrane. Electron microscopy, DNA/protein ratios and S'-nucleotidase determinations codfirmed the purity of the preparation. 2. Both liver and spleen nuclei specifically bound '251-labelled angiotensin I1 (ANG 11) with high affinity (Kd Z 1-0 nmol/l). Saralasin ANG I11 and ANG I1 competed with...
