Some properties of degenerate complete and partial Bell polynomials

Advances in Difference Equations, 2021
In this paper, we study degenerate complete and partial Bell polynomials and establish some new identities for those polynomials. In addition, we investigate the connections between modified degenerate complete and partial Bell polynomials, which are ...

On Sums Over Partially Ordered Sets [PDF]

The Electronic Journal of Combinatorics, 1999
We establish a general theorem for reducing sums of type $\sum_{y\ge x} g(y)$ where $g$ is a mapping from a partially ordered set into an abelian group. Conclusions concern the Möbius function, the principle of inclusion-exclusion, the Tutte polynomial and Crapo's beta invariant.

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

Pattern avoidance in partial permutations [PDF]

, 2011
Motivated by the concept of partial words, we introduce an analogous concept of partial permutations. A partial permutation of length n with k holes is a sequence of symbols $\pi = \pi_1\pi_2 ...

On Partial Sums in Cyclic Groups

, 2015
We are interested in ordering the elements of a subset A of the non-zero integers modulo n in such a way that all the partial sums are distinct. We conjecture that this can always be done and we prove various partial results about this problem.

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Impact of Radiation Therapy on Physical and Psychosocial Health of Adolescents and Young Adults: A Joint Report From the Children's Oncology Group AYA and Radiation Oncology Committees

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.

Approximation of solutions of the stochastic wave equation by using the Fourier series

Modern Stochastics: Theory and Applications, 2018
A one-dimensional stochastic wave equation driven by a general stochastic measure is studied in this paper. The Fourier series expansion of stochastic measures is considered.

Estimates for partial sums of continued fraction partial quotients [PDF]

Pacific Journal of Mathematics, 1986
Let \(\alpha =[0,a_ 1,a_ 2,...]\) be the representation of the irrational number \(\alpha\) as a regular continued fraction and let F be an arithmetic function. Put \(S_ N(F,\alpha):=\sum_{n\leq N}F(a_ n)\). Khinchin proved that if \(F(r)=O(r^{-\delta})\), \(r\to \infty\), for some positive \(\delta\), then \[ (1)\quad (1/N) S_ N(F,\alpha)=(1+o(1 ...
