TL;DR: In this paper, a zero-inflated negative binomial mixed regression model is presented to analyze a set of pancreas disorder length of stay (LOS) data that comprised mainly same-day separations.
Abstract: In many biometrical applications, the count data encountered often contain extra zeros relative to the Poisson distribution. Zero-inflated Poisson regression models are useful for analyzing such data, but parameter estimates may be seriously biased if the nonzero observations are over-dispersed and simultaneously correlated due to the sampling design or the data collection procedure. In this paper, a zero-inflated negative binomial mixed regression model is presented to analyze a set of pancreas disorder length of stay (LOS) data that comprised mainly same-day separations. Random effects are introduced to account for inter-hospital variations and the dependency of clustered LOS observations. Parameter estimation is achieved by maximizing an appropriate log-likelihood function using an EM algorithm. Alternative modeling strategies, namely the finite mixture of Poisson distributions and the non-parametric maximum likelihood approach, are also considered. The determination of pertinent covariates would assist hospital administrators and clinicians to manage LOS and expenditures efficiently.

TL;DR: In-situ U-Th-Pb analyses by ion-microprobe on zircon in intact textural relationships are combined with backscatter and cathodoluminescence analysis and trace element analyses to provide evidence for growth episodes as mentioned in this paper.
Abstract: In-situ U-Th-Pb analyses by ion-microprobe on zircon in intact textural relationships are combined with backscatter and cathodoluminescence
imaging and trace element analyses to provide evidence for growth episodes of zircon. This approach helps: (a) to unravel
the polymetamorphic history of aluminous migmatitic and granitoid gneisses of the regional contact aureole around the Rogaland
anorthosite-norite intrusive complex; and (b) to constrain the age of M 2 ultrahigh-temperature (UHT) metamorphism and the subsequent retrograde M 3 event. All samples yield magmatic inherited zircon of c. 1035 Ma, some an additional group at c. 1050 Ma. This suggests that loss of Pb by volume diffusion in non-metamict zircon is not an important factor even under extreme
crustal conditions. Furthermore, the identical inheritance patterns in aluminous (garnet, cordierite ± osumilite-bearing)
migmatites and orthogneisses indicate a metasomatic igneous instead of a sedimentary protolith for the migmatite. Results
for the M 1 metamorphic event at c. 1000 Ma BP are consistent in all samples, including those from outside the orthopyroxene-in isograd. The latter do not show evidence
for zircon growth during the M 2 metamorphic episode.
Zircon intergrown with or included within M 2 metamorphic minerals (magnetite, spinel, orthopyroxene) give an age of 927 ± 7 Ma (2 σ, n = 20). The youngest observed results are found in zircon outside M 2 minerals, some overgrown by M 3 mineral assemblages (late garnet coronas, garnet + quartz and orthopyroxene + garnet symplectites) and yield a slightly younger
pooled age of 908 ± 9 Ma (2 σ, n = 6). These textures are relative time markers for the crystallization of zircon overgrowths during discrete stages of the
UHT event. These youngest age groups are consistent with the emplacement age of the Rogaland intrusive complex and the last
magmatic activity (Tellnes dyke intrusion), respectively. This is direct and conclusive evidence for UHT metamorphism in the
regional aureole being caused by the intrusions, and corrects earlier notions that the events are not linked. Trace element
behaviour of zircon (Tb/U and Y content) has been tracked through time in the samples and shows variations both within and
between samples. This heterogeneous behaviour at all scales appears to be common in metamorphic rocks and precludes the use
of ‘rules of thumb’ in the interpretation of zircon chemistry, but chemical tracers are useful for recognition of zircon growth
or recrystallization during metamorphism.

TL;DR: In this paper, a conceptual system framework for construction defect management that integrates ontology and augmented reality (AR) with building information modeling (BIM) is proposed to facilitate defect measures and rectifications as well as reduce the reoccurrence of the defect.
