An Improved Interactive Streaming Algorithm for the Distinct Elements Problem

open access: yes, 2014
The exact computation of the number of distinct elements (frequency moment $F_0$) is a fundamental problem in the study of data streaming algorithms. We denote the length of the stream by $n$ where each symbol is drawn from a universe of size $m$.

Inpatient Food Insecurity and Pediatric Hematology Oncology Hospitalization Outcomes

open access: yesPediatric 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.

INTEGRATION OF MULTIPLE LOG DATA FOR ACCURATE POROSITY AND PERMEABILITY ESTIMATION, NIGER DELTA BASIN [PDF]

open access: yesGeological Behavior
The use of well logs is significant to obtain accurate and improved porosity, permeability and watersaturation. This accounts for the ability of the wells to store and transmit fluid (hydrocarbon) and itsavailability potential. Three wells (OB-14, OB-15,

Categorical data analysis using a skewed Weibull regression model

open access: yes, 2017
In this paper, we present a Weibull link (skewed) model for categorical response data arising from binomial as well as multinomial model. We show that, for such types of categorical data, the most commonly used models (logit, probit and complementary log-

Feasibility and Safety of High‐Dose Proton Re‐Irradiation in Recurrent Pediatric Central Nervous System Tumors: A Single‐Institution Retrospective Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Pediatric central nervous system (CNS) tumors often recur despite multimodality therapy. Although re‐irradiation (re‐RT) has historically been limited by concerns for severe late toxicities, modern techniques have renewed interest in this approach. Proton therapy provides dosimetric advantages that may enable curative re‐treatment with

Dense clusters of primes in subsets [PDF]

open access: yes, 2014
We prove a generalization of the author's work to show that any subset of the primes which is `well-distributed' in arithmetic progressions contains many primes which are close together.

Moderate deviations for the determinant of Wigner matrices

open access: yes, 2013
We establish a moderate deviations principle (MDP) for the log-determinant $\log | \det (M_n) |$ of a Wigner matrix $M_n$ matching four moments with either the GUE or GOE ensemble.

Feasibility and Preliminary Efficacy of Integrative Neuromuscular Training for Childhood Cancer Survivors: A Pilot Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...

Research Status and Development Direction of Well Log Cyclostratigraphy

open access: yesCejing jishu
Well log cyclostratigraphy has become the foundation for studying many key scientific issues in the field of geosciences by identifying, extracting, and interpreting astronomical cycles recorded by geophysical logs. This paper analyzes the driving forces

Petrophysical Properties of an Iraqi Carbonate Reservoir Using Well Log Evaluation

open access: yesIraqi Journal of Chemical and Petroleum Engineering, 2020
This research was aimed to determine the petrophysical properties (porosity, permeability and fluid saturation) of a reservoir. Petrophysical properties of the Shuiaba Formation at Y field are determined from the interpretation of open hole log data of ...
