Little research has addressed the heterogeneity and mortality risk in body mass index (BMI) trajectories among older populations. Applying latent class trajectory models to 9,538 adults aged 51 to 77 years from the US Health and Retirement Study (1992–2008), we defined 6 latent BMI trajectories: normal weight downward, normal weight upward, overweight stable, overweight obesity, class I obese u...

An upward drawing of a rooted tree T is a planar straight-line drawing of T where the vertices of T are placed on a set of horizontal lines, called layers, such that for each vertex u of T , no child of u is placed on a layer vertically above the layer on which u has been placed. In this paper we give a linear-time algorithm to obtain an upward drawing of a given rooted tree T on the minimum nu...

Background and aim: Considering the widespread development of implants in dental treatment plans, linear measurements on panoramic radiography are of especial importance. In the present study we investigated the effect of head misalignment up to 15° around vertical and horizontal axes on the magnification rate of digital panoramic radiography in each part of upper and lower jaws. Materia...

In this paper we present a new characterization of switch-regular upward embeddings, a concept introduced by Di Battista and Liotta in 1998. This characterization allows us to define a new efficient algorithm for computing upward planar drawings of embedded planar digraphs. If compared with a popular approach described by Bertolazzi, Di Battista, Liotta, and Mannino, our algorithm computes draw...

During the early years of the 1981-87 decline in Indiana land values, there were reports of decreasing numbers of sales and increasing amounts of land for sale. This situation was reversed about 1987 and continues today as indicated by a majority of Purdue land values survey respondents who believe there is less land on the market now than a year ago and that sales have picked up. The same or l...

We propose a timed extension of LOTOS, denoted TLOTOS, which is upward compatible with the standard LOTOS. It means first that a timed behaviour expression which does not use any language extension will have the same semantics as in standard LOTOS. In addition, we have pushed this upward compatibility one step beyond by requiring and obtaining that all the familiar equivalence laws of standard ...

We give a complete characterization of the class of upward monotone generalized quantifiers Q1 and Q2 over countable domains that satisfy the scheme Q1x Q2y ! Q2y Q1x . This generalizes the characterization of such quantifiers over finite domains, according to which the scheme holds iff either Q1 is 9 or Q2 is 8 (excluding trivial cases). Our result shows that in infinite domains, there are mor...

Title of Document: Upward Flame Spread Over Discrete Fuels Colin H. Miller, Master of Science, 2014 Directed By: Dr. Michael J. Gollner, Assistant Professor, Department of Fire Protection Engineering Upward flame spread over discrete fuels has been analyzed through experimental research on vertical arrays of alternating lengths of PMMA and insulation. By manipulating the lengths of the PMMA fue...

We consider upward planar drawings of directed graphs in the plane (UP), and on standing (SUP) and rolling cylinders (RUP). In the plane and on the standing cylinder the edge curves are monotonically increasing in y-direction. On the rolling cylinder they wind unidirectionally around the cylinder. There is a strict hierarchy of classes of upward planar graphs: UP ⊂ SUP ⊂ RUP. In this paper, we ...

Upward-going muon events in MACRO allow measurement of the ux in the range E 10 to 100 GeV. The ratio of total observed to expected events is 0:74 0:036stat 0:046sys 0:13theor, which when combined with the observed zenith angle distribution ( 1:0 cos 0:1) agrees with the no-oscillation model to no better than 0.1%. The data are in signi cantly greater agreement with the $ vacuum oscillation mod...
