Pediatric Blood &Cancer, EarlyView.ABSTRACT Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a rare pediatric CD30‐positive T‐cell lymphoproliferative disorder with an excellent prognosis, but its genomic drivers are poorly defined. We report three children with skin‐limited disease demonstrating striking molecular heterogeneity, including NPM::ALK, NUP214::FRK, and a novel ...

Bernstein operators of second kind and blending systems
Journal of Numerical Analysis and Approximation Theory, 2017 We consider the fundamental polynomials associated with the Bernstein operators of second kind. They form a blending system for which we study some shape preserving properties. Modified operators are introduced; they have better interpolation properties.

Sign changes in linear combinations of derivatives and convolutions of Polya frequency functions
International Journal of Mathematics and Mathematical Sciences, 1979 We obtain upper bounds on the number of sign changes of linear combinations of derivatives and convolutions of Polya frequency functions using the variation diminishing properties of totally positive functions.

KP solitons, total positivity, and cluster algebras. [PDF]
Proc Natl Acad Sci U S A, 2011 Soliton solutions of the KP equation have been studied since 1970, when Kadomtsev and Petviashvili [Kadomtsev BB, Petviashvili VI (1970) Sov Phys Dokl 15:539–541] proposed a two-dimensional nonlinear dispersive wave ...

Personalized Zebrafish Models for Fusion‐Positive Pediatric Sarcomas
Pediatric Blood &Cancer, EarlyView.ABSTRACT Clinical sequencing efforts have revolutionized our approaches to categorizing pediatric cancers in real time. This has dramatically improved our ability to profile pediatric tumors, identify actionable vulnerabilities, and influence clinical care.

The Role of “Adult‐Onset” Cancer Predisposition Genes in Pediatric Cancer: A Comprehensive Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Current literature estimates that 10% of pediatric cancers are caused by pathogenic or likely pathogenic (P/LP) germline variants in cancer predisposition genes (CPGs). Variants in CPGs thought to increase cancer risk exclusively during adulthood are referred to as “adult‐onset” CPGs (aoCPGs).

Double Bruhat Cells And Total Positivity [PDF]
, 1998 This paper continues algebraic study of total positivity in semisimple algebraic groups undertaken in [3, 4]. The classical theory of total positivity studies matrices whose all minors are nonnegative. Recently, G.

Total positivity criteria for partial flag varieties [PDF]
, 2011 For a simply-connected complex algebraic group G of type A, D, or E, we prove (see C. Geiss et al. (2008) [12], Conjecture 19.2) a new family of total positivity criteria for partial flag varieties G/P, where P is a parabolic subgroup of ...
