OBJECTIVES: Acute Type A aortic dissection remains a life-threatening disease, but there are indications that its surgical mortality is decreasing. The aim of this report was to study how surgical mortality has changed and what influences those changes.METHODS: Nordic Consortium for Acute Type A Aortic Dissection is a retrospective database comprising 1159 patients (mean age 61.6 ± 12.2 years, 68%
Contemporary entrepreneurial education (EE) has global reach and impact, with a growing number of entrepreneurship courses, specializations, and degrees in all parts of the world. There is no longer a question of the significance and demand for EE in the higher education system. At the same time, the interest in scientific knowledge and proven experience of “what works” has accelerated, resulting
Segmentation of grey matter in magnetic resonance images of the spinal cord is an important step in assessing disease state in neurological disorders such as multiple sclerosis. However, manual delineation of spinal cord tissue is time-consuming and susceptible to variability introduced by the rater. We present a novel segmentation method for spinal cord tissue that uses fully convolutional encode
Global supply chain management concerns the management of sourcing, manufacturing, and distribution that take place in different countries before a product is sold and delivered to the final buyers. From the view of the focal manufacturing firm, a global supply chain consists of three key parts: the upstream supply network, the manufacturing network of plants belonging to the focal firm, and the d
This paper is concerned with the estimation of unknown drift functions of stochastic differential equations (SDEs) from observations of their sample paths. We propose to formulate this as a non-parametric Gaussian process regression problem and use an Ito-Taylor expansion for approximating the SDE. To address the computational complexity problem of Gaussian process regression, we cast the model in
Besides friction and wear, airborne particle emission has become a central parameter when evaluating disc brake performance due to its potential adverse health effects as component of ambient air pollution. The pad friction material of brake system is composed of a mixture of ingredients grouped into four material categories: abrasives, reinforcing fibres, lubricants, and fillers. Some other ingre
Cell-based therapies represent a new therapeutic approach for stroke. In 2007, investigators from academia, industry leaders, and members of the National Institutes of Health crafted recommendations to facilitate the translational development of cellular therapies as a novel, emerging modality for stroke from animal studies to clinical trials. This meeting was called Stem Cell Therapies as an Emer
Spindle cell lipomas (SCL) and pleomorphic lipomas (PL) are today considered a single tumor entity (SCLPL). Atypical SCLPL, in contrast, represents a recently recognized related but distinct entity. Here we explored the correlation between genomic features and morphological aspects of SCLPL and atypical SCLPL and the role of the RB1 gene in tumor development. Seventy-one samples from 68 patients w

Ecosystem services from forestry are highly valuable and may be limited by ungulate browsing. Thus, I investigated the impact and seasonality of browsing on Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) using seasonal exclosures. Slightly more than 10 % of the pine trees were browsed at the top shoot, compared to spruce where top shoot browsing was almost non-existent. Pines that h
There exists a lack of laser-based remote sensing methods that give signals with high intensity and directionality. According to previous research, mirrorless lasing can meet these requirements; however, neither the dependence on the gain medium geometry nor the light-matter interaction responsible for the emission has been investigated in detail. This thesis project examined the sideways lasing e

Accounting for the estimated number of undescribed species, Gelechioidea are thought to be among the most species-rich superfamilies of Lepidoptera, with 18,500 described species, including numerous pests of economically significant crops such as cotton, tomato and wheat. Family-level topology of the superfamily and the extent and the number of accepted families have received important revisions t
In this study, a serial production system consisting of two machines and an intermediate finite buffer is considered. The machines have random processing times, and each machine contains one unit of a common critical component that is subject to random breakdown. Broken components must be replaced from an inventory of ready-for-use spare parts to restore machine functionality. This inventory is re
Physiological studies on olfaction frequently ignore the airborne quantities of stimuli reaching the sensory organ. We used a gas chromatography-calibrated photoionization detector to estimate quantities released from standard Pasteur pipette stimulus cartridges during repeated puffing of 27 compounds and verified how lack of quantification could obscure olfactory sensory neuron (OSN) affinities.
Recent literature has highlighted the creation of multiple equivalences as an important factor underpinning the rise of market-based mechanisms for environmental regulation. Extending these insights into the field of renewable energy policy, this article focuses on one example of this trend – namely the principle of technology neutrality as applied under the Flemish tradable green certificate sche
Dissolved organic matter (DOM) is a master variable in aquatic systems. Modern fluorescence techniques couple measurements of excitation emission matrix (EEM) spectra and parallel factor analysis (PARAFAC) to determine fluorescent DOM (FDOM) components and DOM quality. However, the molecular signatures associated with PARAFAC components are poorly defined. In the current study we characterized riv
