Model-Based Engineering (MBE) aims at increasing the e↵ectiveness of engineering by using models as key artifacts in the development process. While empirical studies on the use and the e↵ects of MBE in industry generally exist, there is only little work targeting the embedded systems domain. We contribute to the body of knowledge with a study on the use and the assessment of MBE in that particu...

In model-based engineering (MBE), the abstraction power of models is used to deal with the ever increasing complexity of modern software systems. As models play a central role in MBE-based development processes, for the adoption of MBE in practical projects it becomes indispensable to introduce rigorous methods for ensuring the correctness of the models. Consequently, much effort has been spent...

Disturbance of oxygen-carbon dioxide homeostasis has an impact on cancer. Little is known about the effect of breath training on cancer patients. Here we report our 10-year experience with morning breathing exercises (MBE) in peer-support programs for cancer survivors.We performed a cohort study to investigate long-term surviving patients with lung cancer (LC) and nasopharyngeal cancer (NPC) wh...

We examine whether the previously documented pricing premium for firms’ equity when they meet or beat earnings expectations (MBE) is attributable to a reduction in the cost of equity capital via a reduction in information asymmetry. We measure the latter using the probability of informed trading (PIN) from Easley et al. (1997). We find that PIN decreases (increases) when firms meet or beat (mis...

We investigate a hybrid of two styles of algorithms for deriving bounds for optimization tasks over graphical models: non-iterative message-passing schemes exploiting variable duplication to reduce cluster sizes (e.g. MBE) and iterative methods that re-parameterize the problem’s functions aiming to produce good bounds even if functions are processed independently (e.g. MPLP). In this work we co...

A brief introduction to the MBE technique is presented with main attention to the elemental source MBE. A discussion on the effusion cell as beam source is shortly given starting from ideal cases to real cells homogeneity problems. A short review regarding the thermodynamic approach to the MBE is pointed out. Focusing on the possibility that, despite the fact that MBE processes occur under stro...

We have performed a comparison of magnetoresistance and structure of epitaxial and textured Fe/Cr superlattices grown by molecular-beam epitaxy ~MBE! and magnetron sputtering with either ~110! and ~100! orientations on a variety of substrates. MBE samples grown along the ~100! orientation, exhibit narrower rocking curves ~mosaic spread! and lower saturation resistivities than sputtered samples....

This paper presents a novel framework for HMM-based automatic phonetic segmentation that improves the accuracy of placing phone boundaries. In the framework, both training and segmentation approaches are proposed according to the minimum boundary error (MBE) criterion, which tries to minimize the expected boundary errors over a set of possible phonetic alignments. This framework is inspired by ...

BACKGROUND Microbial synthesis of oleochemicals derived from native fatty acid (FA) metabolism has presented significant advances in recent years. Even so, native FA biosynthetic pathways often provide a narrow variety of usually linear hydrocarbons, thus yielding end products with limited structural diversity. To overcome this limitation, we took advantage of a polyketide synthase-based system...

Sclerocarya birrea (A.Rich.) Hochst (Anacardiaceae) is a savannah tree that has long been used in sub-Saharan Africa as a medicinal remedy for numerous ailments. The purpose of this study was to increase the scientific knowledge about this plant by evaluating the total content of polyphenols, flavonoids, and tannins in the methanol extracts of the leaves and bark (MLE and MBE, respectively), as...
