We consider the growth functions βΓ(n) of amalgamated free products Γ = A ∗C B, where A ∼= B are finitely generated, C is free abelian and |A/C| = |A/B| = 2. For every d ∈ N there exist examples with βΓ(n) ' nβA(n). There also exist examples with βΓ(n) ' e. Similar behaviour is exhibited among Dehn functions. For Slava Grigorchuk, in friendship, with great respect. The first purpose of this not...

We investigate the strange and flavor-singlet electric and magnetic form factors of the nucleon within the framework of the SU(3) chiral quark-soliton model. Isospin symmetry is assumed and the symmetry-conserving SU(3) quantization is employed, rotational and strange-quark mass corrections being included. For the experiments G0, A4, and HAPPEX II we predict the quantitiesG0E+βG 0 M andG s E+βG...

We compared the enhancement effect between a newly synthesized tissue-specific contrast agent, [Gd-DOTA-FPβG], and a commercially available agent, [Gd(DOTA)](-), in a murine model of liver tumor using a clinical magnetic resonance imaging scanner. The colon cancer cell lines with and without β-glucuronidase (βG) expression were implanted into the liver of mice. Self-synthesized gadolinium-based...

CPT-11 is a camptothecin analog used for the clinical treatment of colorectal adenocarcinoma. CPT-11 is converted into the therapeutic anti-cancer agent SN-38 by liver enzymes and can be further metabolized to a non-toxic glucuronide SN-38G, resulting in low SN-38 but high SN-38G concentrations in the circulation. We previously demonstrated that adenoviral expression of membrane-anchored beta-g...

We give a more precise characterisation of the end of the electroweak phase transition in the framework of the effective 3d SU(2)-Higgs lattice model than has been given before. The model has now been simulated at βG = 12 and 16 for M ∗ H = 70 GeV and Higgs masses above the critical mass up to lattices 80 and the data have been used for reweighting. The breakdown of finite volume scaling of the...

Critical cellulase and hemicellulase activities are identified for hydrolysis of ionic liquid (IL) pretreated poplar and switchgrass; hemicellulase rich substrates with largely amorphous cellulose. Enzymes from Aspergillus nidulans were expressed and purified: an endoglucanase (EG) a cellobiohydrolase (CBH), an endoxylanase (EX) and an acetylxylan esterase (AXE). β-Xylosidase (βX) from Selenomo...

This study was part of a farmer-led initiative that fosters transformation in agriculture through improved soil health, benefitting farmer profitability, supporting stable food supply, and preserving the environment. study’s objective to measure effect management strategies on microbial community distribution activity. Four farmers Kansas were accepted into program conduct on-farm comparisons s...

For a discrete group G and a discrete G-space X, we identify the Stone-Čech compactifications βG and βX with the sets of all ultrafilters on G and X, and apply the natural action of βG on βX to characterize large, thick, thin, sparse and scattered subsets of X. We use G-invariant partitions and colorings to define G-selective and G-Ramsey ultrafilters on X. We show that, in contrast to the set-...

Let X be a compact Riemann surface of genus ≥ 2 of constant negative curvature −1. An extremal disk is an embedded (resp. covering) disk of maximal (resp. minimal) radius. A surface containing an extremal disk is an extremal surface. This paper gives formulas enumerating extremal surfaces of genus ≥ 4 up to isometry. We show also that the isometry group of an extremal surface is always cyclic o...
