Estimates of the modulus of continuity of the logarithmic double layer potential

Математичні Студії
For the real part of the Cauchy-type integral, which is known to be the logarithmic double layer potential, we obtain estimates of the modulus of continuity in the closure of domain bounded by an Ahlfors-regular integration curve.

Local exact controllability of the age-dependent population dynamics with diffusion

Abstract and Applied Analysis, 2001
We investigate the local exact controllability of a linear age and space population dynamics model where the birth process is nonlocal. The methods we use combine the Carleman estimates for the backward adjoint system, some estimates in the theory of ...

The exact distribution of the Stein-rule estimator [PDF]

Journal of Econometrics, 1984
This paper derives the exact density of the Stein-rule estimator in the setting of the general linear regression. The derivation is facilitated by the author's development of new algebraic methods that involve an extension of the Weyl calculus. General formulae for the moments of the estimator are also provided.

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

Pediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

THE EXACT ERROR IN ESTIMATING THE SPECTRAL DENSITY AT THE ORIGIN

Journal of Time Series Analysis, 1996
Abstract. This paper derives expressions for the exact bias and variance of a general class of spectral density estimators at the zero frequency, building on the work of Neave (The exact error in spectrum estimates. Ann. Math. Statist. 42 (1971), 961–75) who studied the case where the mean of the series is assumed known.

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

An exact subspace method for fundamental frequency estimation [PDF]

2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013
In this paper, an exact subspace method for fundamental frequency estimation is presented. The method is based on the principles of the MUSIC algorithm, wherein the orthogonality between the signal and and noise subspace is exploited. Unlike the original MUSIC algorithm, the new method uses an exact measure of the angles between the subspaces.

Pediatric Idiopathic Multicentric Castleman Disease Is Often Severe But Responsive to Siltuximab

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Idiopathic multicentric Castleman disease (iMCD) is a potentially fatal immunologic disorder marked by widespread lymphadenopathy and inflammation. Siltuximab, an interleukin‐6 (IL‐6) inhibitor, is the only FDA‐approved treatment for adult patients with iMCD.

On the behaviour of derivative of algebraic polynomials in the regions with cusps

Applied Mathematics in Science and Engineering, 2022
In this paper, we study the behavior of derivatives of algebraic polynomials in bounded and unbounded regions of the complex plane. At the same time, both interior and exterior cusp points are allowed on the boundary of such regions. Bernstein-Walsh-type
