Incomplete dominance of deleterious alleles contributes substantially to trait variation and heterosis in maize. [PDF]

PLoS Genetics, 2017
Deleterious alleles have long been proposed to play an important role in patterning phenotypic variation and are central to commonly held ideas explaining the hybrid vigor observed in the offspring of a cross between two inbred parents.

A Bit-Parallel Tabu Search Algorithm for Finding Es2-Optimal and Minimax-Optimal Supersaturated Designs

Computational and Mathematical Methods, 2023
We prove the equivalence of two-symbol supersaturated designs (SSDs) with N (even) rows, m columns, and smax=4t+i, where i∈0,2 and t∈ℤ≥0 and resolvable incomplete block designs (RIBDs) whose any two blocks intersect in at most N+4t+i/4 points. Using this

Design of a syringe extension device (Chloe SED®) for low-resource settings in sub-Saharan Africa: a circular economy approach

Frontiers in Medical Technology, 2023
Underfunded healthcare infrastructures in low-resource settings in sub-Saharan Africa have resulted in a lack of medical devices crucial to provide healthcare for all.

Comparison Between some Methods of Tackling the Lack of Experimental Units Needed for Application of Factorial Experiments [PDF]

المجلة العراقية للعلوم الاحصائية, 2011
Most of the time the researcher confronts a decrease in the experimental units required when applying a certain design, this problem appears especially when conducting the factorial experiments which mostly need great numbers of experimental units, to ...

Sirolimus for Extracranial Arteriovenous Malformations: A Scoping Review of the Evidence in Syndromic and Non‐Syndromic Cases

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Two Faces of NOTCH1 in Childhood Lymphoblastic T‐Cell Neoplasia: Prognostic Divergence of Mutational and Structural Aberrations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT In pediatric patients, T‐cell lymphoblastic lymphoma (T‐LBL) survival exceeds 80%. Relapse remains associated with limited curative options. Frontline treatment is largely extrapolated from T‐cell acute lymphoblastic leukemia (T‐ALL) treatment, reflecting the ongoing debate, whether both entities represent distinct diseases or variants within ...

Serological Benefit of SARS‐CoV‐2 Vaccination Relative to Infection in Children With Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.

On a Property of Incomplete Blocks

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1959
SUMMARY In a balanced incomplete block design, two orthogonal treatment contrasts may each be split up into inter- and intra-block components, all four components being mutually orthogonal. This property is shown to be closely related to the condition that the two components of a treatment contrast estimate the same thing.
