Codes over certain rings

Information and Control, 1972
A cyclic code over a finite field may be viewed as an ideal in the group algebra of a cyclic group over a finite field. As a possible extension to this case the paper considers linear cyclic codes over the residue ring of integers \(\mathbb Z_m\) as ideals in the group ring \(\mathbb Z_nC_n\). The group ring is semisimple if and only if \((m,n)=1\) and

GENERALIZED REED-MULLER CODES OVER GALOIS RINGS

Advances in Mathematics: Scientific Journal, 2022
A Galois ring may be considered as a common generalization of a finite field and a prime power integer residue ring. The generalized Reed-Muller codes over finite fields were introduced by Kasami et al. and the generalized Reed-Muller codes over prime power integer residue rings were constructed by M. Bhaintwal and S. K. Wasan.

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

Pediatric 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.

Optimal Generalized Quasi-Polycyclic Codes over ${\mathbb{F}}_{\mathit{q}}+\mathit{u}{\mathbb{F}}_{\mathit{q}}$

Mathematics
This paper develops a structural and constructive theory of right generalized quasi-polycyclic (GQPC) codes over the finite chain ring R=Fq+uFq with u2=0, extending the existing field-based GQPC framework to a ring-theoretic setting.

Quantum codes from linear codes over finite chain rings [PDF]

Quantum Information Processing, 2017
In this paper, we provide two methods of constructing quantum codes from linear codes over finite chain rings. The first one is derived from the Calderbank-Shor-Steane (CSS) construction applied to self-dual codes over finite chain rings. The second construction is derived from the CSS construction applied to Gray images of the linear codes over finite

Preferences of Pediatric Patients and Their Caregivers for Chemotherapy‐Induced Nausea and Vomiting Control Endpoints: A Mixed Methods Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Although not always achieved, complete chemotherapy‐induced nausea and vomiting (CINV) control is the conventional goal of CINV prophylaxis. In this two‐center, mixed‐methods study, we sought to understand the preferences of adolescent patients and family caregivers for CINV control endpoints.

γ-Dual Codes over Finite Commutative Chain Rings

Axioms
In this article, the notion of γ-dual codes over finite chain rings is introduced as an extension of dual codes over finite chain rings. Various characteristics and properties of γ-dual codes over finite chain rings are explored.

Inpatient Food Insecurity and Pediatric Hematology Oncology Hospitalization Outcomes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Children with cancer and blood disorders are at risk for food insecurity (FI). We aimed to describe the association of inpatient food insecurity (IFI) and hospitalization outcomes among patients admitted to the pediatric hematology oncology service. Of 325 caregivers screened for IFI, 60 (18.6%) screened positive.

‘They Need to Hear You Say It’: Healthcare Professionals’ Perspectives on Barriers and Enablers to End‐of‐Life Discussions With Adolescents and Young Adults With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...
