to report the oral findings, including dental anomalies, ectopic eruption of the maxillary permanent first molars and periodontal disease and soft tissue alterations, in a subject with apert syndrome. clinical and radiographic examination of a patient with apert syndrome, aged 21 years old, not previously submitted for orthodontic or orthognathic treatment. dental anomalies were present in a pa...

ackground and aim: it is important to evaluate the effect of the type of filling material on deformation and strength of tooth after filling and also the effect of filling depth on quality of restoration of a decayed tooth. material and methods: the orthopantomogram (opg) of the first and second molars of a 28-year-old man was made and the teeth were 3d modeled. the stress-deformation analysis ...

The selection of medical students in Singapore has been a contentious issue for more than 140 years. Initially, students were selected for Madras Medical College, the traditional source for medical officers in early Singapore, by a combination of an examination as well as an observed preceptorship at the General Hospital. With the establishment of the medical school in Singapore in 1905, the se...

Positive effects of competitor species richness on competitor productivity can be more pronounced at a scale that includes heterogeneity in 'bottom-up' environmental factors, such as the supply of limiting nutrients. The effect of species richness is not well understood in landscapes where variation in 'top-down' factors, such as the abundance of predators or herbivores, has a strong influence ...

A major focus of modern population genetics involves using polymorphism data in order to identify regions impacted by recent positive selection (so-called genomic scans). Recently, methodology has been proposed not to identify individual loci, but rather to quantify genomic recurrent hitchhiking (RHH) parameters using this same type of polymorphism data. I here examine to what extent genomic sc...

We study the distribution of the adaptive LASSO estimator (Zou (2006)) in finite samples as well as in the large-sample limit. The largesample distributions are derived both for the case where the adaptive LASSO estimator is tuned to perform conservative model selection as well as for the case where the tuning results in consistent model selection. We show that the finite-sample as well as the ...

In an attempt to determine if selection bias could be a reason that religious attendance and depression are related, the predictive value of elevated depressive symptoms for a decrease in future attendance at religious services was examined in a longitudinal panel of 1,673 Dutch adults. Religious attendance was assessed yearly over five years using the single question, "how often do you attend ...

There is growing belief that countries with better financing environments are associated with higher economic growth because they facilitate entrepreneurship and hence the Schumpeterian process of 'creative destruction'. This dissertation explores this hypothesis in more detail by understanding how the financing environment for new ventures impacts outcomes such as individuals' decision to beco...
