Multi‐institutional study on image quality for a novel CBCT solution on O‐ring linac
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Introduction This work presents a multi‐institutional study on image quality provided by a novel cone beam computed tomography (CBCT). The main goal is to investigate the consistency of imaging performance across multiple institutions.

Marcinkiewicz integrals with variable kernels on Hardy and weak Hardy spaces
Journal of Function Spaces and Applications, 2010 In this article, we consider the Marcinkiewicz integrals with variable kernels defined by μΩ(f)(x)=(∫0∞|∫|x−y|≤tΩ(x,x−y)|x−y|n−1f(y)dy|2dtt3)1/2, where Ω(x,z)∈L∞(ℝn)×Lq(Sn−1) for q > 1.

Arens Algebras and Matricial Spaces
Вестник КазНУ. Серия математика, механика, информатика, 2019 Let M be a finite von Neumann algebra equipped with a finite faithful normal trace and let Lp(M; ) be the corresponding noncommutative Lp space of -measurable operators associated with the couple (M; ), 1 ≤ p < ∞. Let MN be the algebra of all complex N

Some estimates for commutators of Littlewood-Paley g-functions
Open Mathematics, 2021 The aim of this paper is to establish the boundedness of commutator [b,g˙r]\left[b,{\dot{g}}_{r}] generated by Littlewood-Paley gg-functions g˙r{\dot{g}}_{r} and b∈RBMO(μ)b\in {\rm{RBMO}}\left(\mu ) on non-homogeneous metric measure space.

Planar Ultrametric Rounding for Image Segmentation [PDF]
, 2015 We study the problem of hierarchical clustering on planar graphs. We formulate this in terms of an LP relaxation of ultrametric rounding. To solve this LP efficiently we introduce a dual cutting plane scheme that uses minimum cost perfect matching as a ...

On projections and monotony in Lp -spaces
Manuscripta Mathematica, 1979 In this paper we investigate the connection between the range of nearest point projections in Lp -spaces and monotony properties of the projection operator. We show e.g.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background The dose‐averaged linear energy transfer (LETD) in proton therapy (PT) has in pre‐clinical studies been linked to the relative biological effectiveness (RBE) of protons. Until recently, the most common PT delivery method in prostate cancer has been double‐scattered PT, with LETD only available through dedicated Monte Carlo (MC ...

Approximation of the image of the Lp ball under Hilbert-Schmidt integral operator
Demonstratio Mathematica, 2023 In this article, an approximation of the image of the closed ball of the space Lp{L}_{p} (p>1p\gt 1) centered at the origin with radius rr under Hilbert-Schmidt integral operator F(⋅):Lp→LqF\left(\cdot ):{L}_{p}\to {L}_{q}, 1p+1q=1\frac{1}{p}+\frac{1}{q}=

Algebraic genericity of strict-order integrability [PDF]
, 2010 We provide sharp conditions on a measure µ defined on a measurable space X guaranteeing that the family of functions in the Lebesgue space Lp (µ, X) (p ≥ 1) which are not integrable with order q for any q > p (or any q < p) contains, except for zero ...

Schur and Fourier multipliers of an amenable group acting on non-commutative Lp-spaces [PDF]
Trans. Amer. Math. Soc. 367 (2015), no. 10, 6997-7013, 2013 Consider a completely bounded Fourier multiplier phi of a locally compact group G, and take 1 <= p <= infinity. One can associate to phi a Schur multiplier on the Schatten classes S_p(L^2 G), as well as a Fourier multiplier on Lp(LG), the non-commutative Lp-space of the group von Neumann algebra of G.
