Let \(q\) be an odd prime power, \(\mathbb{F}_q\) the finite field of order \(q\), \(m\) a positive integer, and \(R= \mathbb{F}_q[X]/(X^{2^m}-1)\). The author shows that the following \(m+1\) elements of \(R\) are idempotents, \[ e_0(X):=2^{-m}\sum_{j=0}^{2^m-1}X^j, \qquad e_i(X):=2^{i-m-1}\left(1+\sum_{k=i+1}^m S_k(X)-S_i(X)\right) \] for \(1\leq i ...

ABSTRACT Background Childhood aplastic anemia (AA) is a rare disease, and both the disease itself and its treatment cause significant morbidity. We aimed to determine the contemporary incidence of childhood AA in Finland, to compare the clinical characteristics of AA against inherited bone marrow failure syndromes (IBMFS) and refractory cytopenia of ...

On the symbol-pair distances of repeated-root constacyclic codes of length 2ps
Let p be an odd prime, and λ be a nonzero element of the finite field F p m . The λ -constacyclic codes of length 2 p s over F p m are classified as the ideals of quotient ring F p m [ x ] 〈 x 2 p s − λ 〉 in terms of their generator polynomials. Based on

Determining Parental Factors for Clinical Trial Attrition in Pediatric Acute Lymphoblastic Leukemia
ABSTRACT Background/Objectives Despite high enrollment rates on Children's Oncology Group (COG) protocols, attrition after initial consent is challenging, introducing bias and prolonging trial completion. While adult oncology literature has identified predictors of withdrawal, little is known about caregiver decision‐making for child participation in ...

Generating m-Ary Gray Codes and Related Algorithms
In this work, we systematize several implementations of the Gray code over an alphabet with m≥2 elements, which we present in C code so that they can be used directly after copying from the text. We consider two variants—reflected and modular (or shifted)

ABSTRACT Background Sickle cell disease (SCD) has undergone major changes in the last decades. Its prevalence has been steadily increasing and numerous advances have been made in the management of the disease. However, the effect in real‐life setting of these major changes is unknown, particularly in a Canadian environment. Procedure We aimed to assess

ABSTRACT Background Timely cancer diagnosis in children and adolescents is important to improving outcomes. We aimed to quantify time to diagnosis and assess variations by patient, demographic and system‐level factors. Procedure We conducted a population‐based study of individuals aged 0–19 years diagnosed with one of 12 cancers from 2010 to 2022 in ...

Bounds on Subspace Codes Based on Subspaces of Type (m,1) in Singular Linear Space
The Sphere-packing bound, Singleton bound, Wang-Xing-Safavi-Naini bound, Johnson bound, and Gilbert-Varshamov bound on the subspace codes n+l,M,d,(m,1)q based on subspaces of type (m,1) in singular linear space Fq(n+l) over finite fields Fq are presented.
