On prefix normal words and prefix normal forms
Theoretical Computer Science, 2017 A $1$-prefix normal word is a binary word with the property that no factor has more $1$s than the prefix of the same length; a $0$-prefix normal word is defined analogously. These words arise in the context of indexed binary jumbled pattern matching, where the aim is to decide whether a word has a factor with a given number of $1$s and $0$s (a given ...

Local dynamics of aperiodic chains with unidirectional couplings [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамикаChains of N unidirectionally coupled nonlinear first-order equations are considered, where the value of the last element is determined through the first element of the chain. The aim of this work is to investigate the local – in the neighborhood of

Stability and Hopf bifurcation periodic orbits in delay coupled Lotka-Volterra ring system
Open Mathematics, 2019 In this paper, we consider a class of delay coupled Lotka-Volterra ring systems. Based on the symmetric bifurcation theory of delay differential equations and representation theory of standard dihedral groups, properties of phase locked periodic ...

Normal form analysis of nonlinear oscillator equations with automated arbitrary order expansions [PDF]
Journal of Theoretical, Computational and Applied MechanicsArbitrary order expansions for the automatic reduction and solutions of nonlinear vibratory systems have been developed successfully within the realm of the direct parametrisation of invariant manifolds.

Normal forms in function fields [PDF]
Proceedings of the international symposium on Symbolic and algebraic computation, 1990 We consider function fields of functions of one variable augmented by the binary operation of composition of functions. It is shown that the straightforward axiomatization of this concept allows the introduction of a normal form for expressions denoting elements in such fields. While the description of this normal form seems relatively intuitive, it is

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with sickle cell disease (SCD) face multiple acute and chronic medical complications that may impact their quality of life as reported by patients themselves. Health‐related social needs (HRSNs), such as food and housing insecurity, are common in people with SCD, but the association between HRSNs and patient‐reported ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Combined oral contraceptive (COC) use in obese adult women dramatically increases the relative risk of developing a pulmonary embolism (PE). The risk of a PE in obese adolescent females taking contraceptives is currently unknown. The purpose of this investigation was to determine the effect of body mass index (BMI) and contraceptive

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer, with an overall survival now surpassing 90% in developed countries. However, treatments are not without adverse effects. In this study, we apply the severe toxicity‐free survival (STFS) framework to determine the prevalence of 21 physician‐defined severe ...
