On the average Steiner distance of graphs with prescribed properties
Discrete Applied Mathematics, 1997 The Steiner distance of a set \(S\) of vertices in a connected graph \(G\), \(d_G(S)\), is the number of edges in a smallest Steiner tree for \(S\). The average Steiner distance \(\mu _n(G)\) of \(G\) is the average of the Steiner distances of all \(n\)-subsets of \(V(G)\).

The Anatomical Record, EarlyView.Abstract Maternal and neonatal morbidity and mortality have declined dramatically during the last century. Historical data are therefore important sources to study the evolutionary selection pressures related to childbirth and how they have fluctuated over time.

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis
The Anatomical Record, EarlyView.Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.

Geometric Models of Local Optimization of Highway Networks that Improve the Configuration of Tracing in Functional Zones [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesThe article discusses the improvement of methods for discrete local optimization of highway tracing in the context of planning urban transport networks. Tracing and building the optimal configuration of the highway network is one of the key tasks in city

Analysis of some statistics for increasing tree families [PDF]
Discrete Mathematics & Theoretical Computer Science, 2004 This paper deals with statistics concerning distances between randomly chosen nodes in varieties of increasing trees. Increasing trees are labelled rooted trees where labels along any branch from the root go in increasing order.

The Anatomical Record, EarlyView.Abstract The Australasian crocodylian fossil record is dominated by the extinct endemic clade Mekosuchinae, with known members spanning the Eocene‐to‐Holocene. This diverse clade exhibited high morphological disparity, from early members superficially similar to Crocodylus, to more terrestrial forms later in the clade's evolutionary history.

British Educational Research Journal, EarlyView.Abstract This study examines the under‐theorized political role and identity of Chinese international students, who emerge as significant actors caught between U.S. soft power ambitions and rising geopolitical suspicion. Amid escalating U.S.‐China tensions, these students are forced to confront environments shaped by competing geopolitical discourses ...
