K− over K+ multiplicity ratio for kaons produced in DIS with a large fraction of the virtual-photon energy

2018

The K$^{-}$ over K$^{+}$ multiplicity ratio is measured in deep-inelastic scattering, for the first time for kaons carrying a large fraction $z$ of the virtual-photon energy. The data were obtained by the COMPASS collaboration using a 160 GeV muon beam and an isoscalar $^6$LiD target. The regime of deep-inelastic scattering is ensured by requiring $Q^2>1$ (GeV/$c)^2$ for the photon virtuality and $W>5$ GeV/$c^2$ for the invariant mass of the produced hadronic system. Kaons are identified in the momentum range from 12 GeV/$c$ to 40 GeV/$c$, thereby restricting the range in Bjorken-$x$ to $0.010.75$. For very large values of $z$, $i.e.$ $z>0.8$, we observe the kaon multiplicity ratio to fall …

Multiplicity of ground states for the scalar curvature equation

2019

We study existence and multiplicity of radial ground states for the scalar curvature equation $$\begin{aligned} \Delta u+ K(|x|)\, u^{\frac{n+2}{n-2}}=0, \quad x\in {{\mathbb {R}}}^n, \quad n>2, \end{aligned}$$when the function $$K:{{\mathbb {R}}}^+\rightarrow {{\mathbb {R}}}^+$$ is bounded above and below by two positive constants, i.e. $$0 0$$, it is decreasing in (0, 1) and increasing in $$(1,+\infty )$$. Chen and Lin (Commun Partial Differ Equ 24:785–799, 1999) had shown the existence of a large number of bubble tower solutions if K is a sufficiently small perturbation of a positive constant. Our main purpose is to improve such a result by considering a non-perturbative situation: we ar…

Multiplicity and history have a detrimental effect on survival in patients with T1G3 bladder tumors selected for conservative treatment.

2008

Purpose: In the absence of Tis tumor we assessed whether history and multiplicity have a detrimental effect on conservative treatment in carefully selected patients with T1G3 bladder carcinoma. Materials and Methods: Between January 1976 and December 1999, 165 select patients with T1G3 bladder tumors were conservatively treated with transurethral resection plus adjuvant intravesical therapy. Patients with concomitant or previous Tis, previous T1G3, tumor size greater than 3 cm and more than 3 lesions were excluded from analysis. Repeat transurethral resection was not routinely performed. However, cytology had to be negative for atypia before the start of adjuvant intravesical therapy. Resul…
