Equationally defined classes of semigroups [PDF]

open access: yes, 2023
We apply, in the context of semigroups, the main theorem from~\cite{higjac} that an elementary class $\mathcal{C}$ of algebras which is closed under the taking of direct products and homomorphic images is defined by systems of equations.

Congruences of maximum regular subsemigroups of variants of finite full transformation semigroups [PDF]

open access: yes
Let X be the full transformation monoid over a finite set X, and fix some a ∈ X of rank r. The variant aX has underlying set X , and operation f * g = fag. We study the congruences of the subsemigroup P = Reg(aX) consisting of all regular elements of aX,

Algebras defined by equations [PDF]

open access: yes, 2019
We show that an elementary class of algebras is closed under the taking of homomorphic images and direct products if and only if the class consists of all algebras that satisfy a set of (generally simultaneous) equations.

Some weighted estimates for Littlewood-Paley functions and radial multipliers [PDF]

open access: yes, 2003
人間社会研究域学校教育系We prove some weighted estimates for certain Littlewood-Paley operators on the weighted Hardy spaces Hwp (0 < P ≤ 1) and on the weighted Lp spaces. We also prove some weighted estimates for the Bochner-Riesz operators and the spherical means.

𝐻^{𝑝}-classes on rank one symmetric spaces of noncompact type. I. Nontangential and probabilistic maximal functions [PDF]

open access: yes, 1986
Two kinds of H p {H^p} -classes of harmonic functions are defined on a general rank one symmetric space of noncompact type. The first one is introduced by using a nontangential maximal function.

Some remarks on normalized matching [PDF]

open access: yes, 1983
A new class of LYM orders is obtained, and several results about general LYM orders are proved. (1) Let A1 ⊂ A2 ⊂ … ⊂ Ar be a chain of subsets of [n] = {l,…,n}. Let 〈ai〉 and 〈bi〉 be two nondecreasing sequences with ai ⩽ bi for l ⩽ i ⩽ r.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Survival Outcomes and Complications Among Canadian Children With Retinoblastoma: A Population‐Based Report From CYP‐C

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.
