FEBS Open Bio, EarlyView.Phenotypic plasticity in a newly established set of EGFR inhibitor‐adapted NSCLC cell lines during adaptation and in established cell lines. Here, we introduce novel sublines of the EGFR‐mutant non‐small cell lung cancer (NSCLC) cell lines HCC827 and HCC4006 adapted to the EGFR kinase inhibitors gefitinib (HCC827rGEFI2μm, HCC4006rGEFI1μm), erlotinib ...

The Boundedness on Mixed Hardy Spaces
Journal of Function Spaces, 2020 The boundedness of operators on Hardy spaces is usually given by atomic decomposition. In this paper, we obtain the boundedness of singular integral operators in mixed Journé class on mixed Hardy spaces by a direct method.

Weighted inequalities for singular integral operators on the half-line [PDF]
, 2014 We prove weighted estimates for singular integral operators which operate on function spaces on a half-line. The class of admissible weights includes Muckenhoupt weights and weights satisfying Sawyer's one-sided conditions.

Long‐term stability analysis of beam shape in a robotic radiosurgery system
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose This study aimed to investigate the long‐term stability of CyberKnife beam profile parameters and assess their compliance with existing quality assurance (QA) guidelines. We evaluated beam profiles in both standard and diagonal planes over 3.5 years post‐installation to detect potential issues and ensure consistent beam quality.

Analogue Sochocky formulae for integral operators with additional logarithmic singularity
Журнал Белорусского государственного университета: Математика, информатика, 2018 In this paper we prove the limit formulas for singular integrals of the form. Limit values of such integrals are expressed in terms of singular integral operators and also integral operators.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose This study aims to develop a CycleGAN based denoising model to enhance the quality of low‐dose PET (LDPET) images, making them as close as possible to standard‐dose PET (SDPET) images. Methods Using a Philips Vereos PET/CT system, whole‐body PET images of fluorine‐18 fluorodeoxyglucose (18F‐FDG) were acquired from 37 patients to ...

Compositions of singular integral operators
Journal of Functional Analysis, 1982 AbstractThe composition of two Calderón-Zygmund singular integral operators is given explicitly in terms of the kernels of the operators. For φ ϵ L1(Rn) and ε = 0 or 1 and ∝ φ = 0 if ε = 0, let Ker(φ) be the unique function on Rn + 1 homogeneous of degree −n − 1 of parity ε that equals φ on the hypersurface x0 = 1.

Algebraic Properties of Cauchy Singular Integral Operators on the Unit Circle
, 2016 In this paper we study algebraic properties of singular integral operators with Cauchy kernel on the $L^{2}$ space of the unit circle. We give an operator equation characterization for this class of Cauchy singular integral operators.
