Threshold hypergraphs

Discrete Mathematics, 1985
Threshold graphs were introduced by \textit{V. Chvátal} and \textit{P. L. Hammer} [Ann. Discrete Math. 1, 145-162 (1977; Zbl 0384.90091)]. They gave three equivalent characterizations of these graphs. These characterizations were generalized for hypergraphs by \textit{M. Ch. Golumbic} [Combinatorics, Keszthely 1976, Colloq. Math.

The Role of Invasive Procedures in the Treatment of Complicated Gastrointestinal Graft‐Versus‐Host Disease in Pediatric Patients

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Gastrointestinal graft‐versus‐host disease (GI GVHD) following hematopoietic stem cell transplant is typically managed with medical therapy, but surgery and angioembolization may be warranted in selected cases with life‐threatening complications.

An investigation of thresholds in air pollution-mortality effects [PDF]

, 2004
In this paper we introduce and implement new techniques to investigate threshold effects in air pollution-mortality relationships. Our key interest is in measuring the dose-response relationship above and below a given threshold level where we allow for ...

Balancing with Thresholds

, 2017
The paper presents a general formal framework representing the role of balancing of values in interpretation of statutory rules. The model developed here is an extension of the model of teleological interpretation, where a given interpretive outcome is justified if it satisfies a given goal (or a set of goals).

Ethnic Differences in the Association Between SOD2 rs4880 and Hepatotoxicity in Pediatric Acute Lymphoblastic Leukemia: A Report From the REDIAL Consortium

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Treatment‐associated hepatotoxicity (TAH) is a common complication of pediatric acute lymphoblastic leukemia (ALL) treatment, but genetic risk factors remain poorly understood. We evaluated the SOD2 rs4880 variant in 544 children with ALL at Texas Children's Hospital. After adjusting for demographic and clinical covariates, the rs4880 C allele

Error threshold in finite populations

, 1998
A simple analytical framework to study the molecular quasispecies evolution of finite populations is proposed, in which the population is assumed to be a random combination of the constiyuent molecules in each generation,i.e., linkage disequilibrium at ...

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.

Critical period for Italian ryegrass (Lolium perenne L. spp. multiflorum) control in winter wheat in North Carolina

Weed Technology
Field studies were conducted in North Carolina to determine the critical period of weed control (CPWC) for Italian ryegrass in winter wheat. Soft red winter wheat was planted in late fall in 2017 and 2018 in no-till fields near Salisbury, NC.

Video Shot Boundary Detection based on Multifractal Analisys [PDF]

Telfor Journal, 2011
Extracting video shots is an essential preprocessing step to almost all video analysis, indexing, and other content-based operations. This process is equivalent to detecting the shot boundaries in a video.
