The pion production mechanism is explored based on the ultrarelativistic quantum molecular dynamics model (UrQMD) in which $\mathrm{\ensuremath{\Delta}}$-mass dependence of $\mathcal{M}$ matrix and momentum ${p}_{N\mathrm{\ensuremath{\Delta}}}$ $N\mathrm{\ensuremath{\Delta}}\ensuremath{\rightarrow}NN$ cross sections are taken into account. By analyzing time evolution rate density overlapped reg...

Let $H \xrightarrow{s} G$ denote that any edge-coloring of $H$ by $s$ colors contains a monochromatic $G$. The degree Ramsey number $r_{\Delta}(G;s)$ is defined to be $\min \{ \Delta(H): H G \}$, and the bipartite $br_{\Delta}(G;s)$ \textrm{ } \chi(H) = 2 \}$. In this note, we show $r_{\Delta}(K_{m,n};s)$ linear on $n$ with fixed $m$. We also evaluate for paths other trees.

Let $P$ be the isotropic nearest neighbor transition operator on a homogeneous tree. We consider $\lambda$-eigenfunctions of for $\lambda$ outside its $\ell^2$ spectrum, i.e., eigenfunctions with eigenvalue $\gamma=\lambda - 1$ Laplace $Delta=P- \mathbb I$, and also $\lambda-$polyharmonic functions, that is, union kernels $(Delta-\gamma I)^n$ $n\geqslant 0$. prove that, suitable Banach space ge...

BACKGROUND The literature describes contradictory data regarding the onset of the baroreflex reduction in spontaneously hypertensive rats. OBJECTIVE This investigation was undertaken to evaluate the baroreflex function in 13-week-old spontaneously hypertensive rats. METHODS Male Wistar Kyoto (n=15) and spontaneously hypertensive rats (n=15) aged 13 weeks were studied. Cannulas were inserted...

The partial oxidation of [Ni(II/II)(2)(RCS(2))(4)] (R = Et (1), n-Pr (2), and n-Bu (3)) with iodine affords the MMX chain compounds [Ni(II/III)(2)(RCS(2))(4)I](infinity) (R = Et (4), n-Pr (5), and n-Bu (6)), respectively. The crystal structures of 4-6 consist of neutral one-dimensional (1-D) chains with a repeating -Ni-Ni-I- unit. The room-temperature (RT) structure of 4 indicates a charge-pola...

The Brassica napus gene, Cel16, encodes a membrane-anchored endo-1,4-beta-glucanase with a deduced molecular mass of 69 kD. As for other membrane-anchored endo-1,4-beta-glucanases, Cel16 consists of a predicted intracellular, charged N terminus (methionine(1)-lysine(70)), a hydrophobic transmembrane domain (isoleucine(71)-valine(93)), and a periplasmic catalytic core (lysine(94)-proline(621)). ...

When [8-(14)C]-N(6)-(Delta(2)-isopentenyl) adenosine is incubated with the endosperm of corn (2 weeks after pollination), it is converted to [(14)C]-N(6)-(4-hydroxy-3-methylbut-2-trans-enyl) adenosine, trans-ribosylzeatin. This biosynthetic step, N(6)-(Delta(2)-isopentenyl) adenosine to ribosylzeatin, also occurs in the mycorrhizal fungus, Rhizopogon roseolus.
