Predictive Value of Modified Lung Ultrasound Score for Late Respiratory Diseases in Premature Infants: A Retrospective Cohort Analysis

open access: yesJournal of Clinical Ultrasound, EarlyView.
This study is to assess the predictive value of the modified lung ultrasound score (mLUS) for late respiratory diseases in premature infants born before 32 weeks of gestation. It is recommended that the use of mLUS scoring be promoted in clinical practice for the early screening of high‐risk preterm infants.

L’interprétation stochastique du sociogramme et le problème des choix exceptionnels; A statistical interpretation of the sociogram and the determination of exceptional choice [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2012
The mutual designation of a preferred member among a group, be it for presidency, a special mandate or even for psychosocial purposes, proceeds frequently by Moreno’s sociogram technique: in its simpler form, each member votes for some other member, and ...

Properly Colored Cycles in Edge‐Colored Balanced Bipartite Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT Let G n , n c ${G}_{n,n}^{c}$ denote a (not necessarily properly) edge‐colored balanced bipartite graph on 2 n $2n$ vertices, that is, in which every edge is assigned a color. A cycle C $C$ in G n , n c ${G}_{n,n}^{c}$ is called properly colored if any two consecutive edges of C $C$ have distinct colors. A properly colored cycle‐factor of G n ,

Another Proof of the Generalized Tutte—Berge Formula for f $f$‐Bounded Subgraphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT Given a nonnegative integer weight f ( v ) $f(v)$ for each vertex v $v$ in a multigraph G $G$, an f $f$‐bounded subgraph of G $G$ is a multigraph H $H$ contained in G $G$ such that d H ( v ) ≤ f ( v ) ${d}_{H}(v)\le f(v)$ for all v ∈ V ( G ) $v\in V(G)$.

The Independence Ratio of 4‐Cycle‐Free Planar Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT We prove that every n $n$‐vertex planar graph G $G$ with no triangle sharing an edge with a 4‐cycle has independence ratio n ∕ α ( G ) ≤ 4 − ε $n\unicode{x02215}\alpha (G)\le 4-\varepsilon $ for ε = 1 ∕ 30 $\varepsilon =1\unicode{x02215}30$. This result implies that the same bound holds for 4‐cycle‐free planar graphs and planar graphs with no ...
