An envelope method for analysing sequential pattern formation
We examine sequential spatial pattern formation in a tissue interaction model for skin organ morphogenesis. Pattern formation occurs as a front sweeps across the domain leaving in its wake a steady state spatial pattern.

Channel formation in draining suspensions
We analyse how particles adhering to a wall can create tree-like structures (or flat trees) by an erosive flow. We vary the physical and chemical properties of the fluid and highlight their influences on the patterns observed.

ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.

Perspectives on Intra- and Intercellular Trafficking of Hedgehog for Tissue Patterning
Intercellular communication is a fundamental process for correct tissue development. The mechanism of this process involves, among other things, the production and secretion of signaling molecules by specialized cell types and the capability of these ...

ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

Self-Adaptive pattern formation with battery-powered robot swarms
This paper presents a distributed, energy-Aware algorithm for an autonomous deployment of battery-powered robots in a specified pattern. While each robot gradually discharges and leaves the formation to recharge, the algorithm presented in this paper ...

Molecular Oblivious Robots: A New Model for Robots With Assembling Capabilities
Research in theoretical swarm robotics focuses on models that assign to robots a minimal set of capabilities. One of the models well investigated is certainly $\mathcal {OBLOT}$ , addressing the case of distributed robots that are, anonymous, without ...

ABSTRACT Background Osteosarcoma (OS) and Ewing sarcoma (EWS) are the most common primary bone cancers in children, but acute thrombosis is poorly characterized in this population. Our study evaluated the rates of venous thromboembolism (VTE) and associated risk factors in pediatric patients with bone sarcomas treated over a 10‐year period encompassing

ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...

OXYGEN GRADIENTS CAUSE PATTERN ORIENTATION IN DICTYOSTELIUM CELL CLUMPS [PDF]
We have investigated the formation of the prestalk-prespore pattern in Dictyottelium discoideum. Pattern formation occurs in clumps of Dictyostelium cells embedded in agar under a 100% oxygen atmosphere.
