The social triad—a group of three people—is one of the simplest and most fundamental social groups. Extensive network and social theories have been developed to understand its structure, such as triadic closure and social balance. Over the course of a triadic closure—the transition from two ties to three among three users, the strength dynamics of its social ties, however, are much less well un...

In the past, most researchers focused on the efficacy of tie-strength in various applications for both online and offline social networks. However, how tie-strength can help in the analysis of online social networks was a commonly neglected issue. The massive size and recording properties of online social networks offer the possibility to measure tie-strength objectively. In this study, we exam...

Bow-tie antenna is one of wideband antennas [1]. It has been reported that the bow-tie antenna has been miniaturized by adding folded elements [2]. In this paper, it is shown that bending the bow-tie antenna with folded elements is effective method for miniaturization. The bent bow-tie antenna with folded elements can be more miniaturized than conventional bow-tie antenna with folded elements, ...

Objective To compare the outcomes of securing full-thickness skin grafting (FTSG) with through-and-through mattress suturing versus the classic tie-over and pressure dressing and identify the associated risk factors of graft failure. Methods A single-institution, retrospective case series of patients who had undergone excision of head and neck skin lesions requiring FTSG over a 10-year period...

BACKGROUND Skin grafting is a frequent surgical procedure used to reconstruct a soft-tissue deficit. Tie-over bolster dressing is the traditional technique made to fix the graft to the recipient area. This dressing does not always provide satisfactory results in some difficult body areas, with poor skin graft taking as an outcome. Here, we used a soft "polyurethane sponge" as a compressive tool...

Models of dynamic networks - networks that evolve over time - have manifold applications. We develop a discrete-time generative model for social network evolution that inherits the richness and flexibility of the class of exponential-family random graph models. The model - a Separable Temporal ERGM (STERGM) - facilitates separable modeling of the tie duration distributions and the structural dy...

Many schools in large urban districts have more applicants than seats. Centralized school assignment algorithms ration seats at over‐subscribed using randomly assigned lottery numbers, non‐lottery tie‐breakers like test scores, or both. The New York City public high match illustrates the latter, scores and other criteria to rank city's screened schools, combined with tie‐breaking rest. We show ...

Terrestrial laser scanners have become a standard piece of surveying equipment, used in diverse fields like geomatics, manufacturing and medicine. However, the processing of today’s large point clouds is time-consuming, cumbersome and not automated enough. A basic step of post-processing is the registration of scans from different viewpoints. At present this is still done using artificial targe...

This paper develops a new test, the trinomial test, for pairwise ordinal data samples to improve the power of the sign test by modifying its treatment of zero differences between observations, thereby increasing the use of sample information. Simulations demonstrate the power superiority of the proposed trinomial test statistic over the sign test in small samples in the presence of tie observat...

BACKGROUND Endothelial receptor tyrosine kinases include 3 members of the vascular endothelial growth factor receptor (VEGFR) family and 2 members of the angiopoietin receptor (Tie) family. In addition, the VEGF(165) isoform binds to neuropilin-1 (NP-1), a receptor for collapsins/semaphorins. The importance of these receptors for vasculogenesis and angiogenesis has been shown in gene-targeted m...
