The influence of supranational regimes has dramatically increased in the last decades. How this influence is manifested and which consequences it has had and continues to have on education is discussed in this paper. More specifically, the paper highlights lifelong learning and the Bologna process seen as projects, the explicit aims of which starkly contrast to their effects on such vital issues a
With a new surgical instrument, a haemostatic dissecting tool driven by ultrasonic energy, different surgical procedures is described within the neck, the chest, and abdomen both for open and laparo- and thoracoscopic procedures. Also orthopedic procedures are described. I also wrote the chapter 5: Esophageal resection with the Ultracision blade and shears.
As custom multicore architectures become more and more common for DSP applications, instruction selection and scheduling for such applications and architectures become important topics. In this paper, we explore the effects of defining the problem of finding an optimal instruction selection and scheduling as a constraint satisfaction problem (CSP). We incorporate methods based on sub-graph isomorp
A Surprisingly high degree of structural and compositional dynamics is observed in the system LiBH4-LiCl as a function of temperature and time. Rietveld refinement of synchrotron radiation powder X-ray diffraction (SR-PXD) data reveals that Cl- readily substitutes for BH4- in the Structure of LiBH4. Prolonged heating a sample of LiBH4-LiCl (1:1 molar ratio) above the phase transition temperature a
Nanovials, microarrays, and microfluidics are brought together for the exploration of complex biological problems.
We propose that the mechanical property of the interface between an implant and its surrounding tissues is critical for the host response and the performance of the device. The interfacial mechanics depends on several different factors related to the physical shape of the device and its surface as well as properties of the host tissue and the loading conditions of the device and surrounding tissue
The problem of recovering scene structure and camera motion from images has a number of inherent ambiguities. In this paper, configurations of points and cameras are analyzed for which the image points alone are insufficient to recover the scene geometry uniquely. Such configurations are said to be critical. For two views, it is well-known that a configuration is critical only if the two camera ce
A way to use adiabatic radiofrequency pulses and modulated magnetic-field gradient pulses, together constituting a "shim pulse," for NMR spectroscopy and imaging is demonstrated. These pulses capitalize on phase shifts derived from probe gradient coils to compensate for nonlinear intrinsic main magnetic field homogeneity for spectroscopy, as well as for deviations from linear gradients for imaging
The most common PID design methods in industry are based on formulas. This article will present some major advantages of instead using the power of computer based softwares for PID controller design. The Matlab based software used in this work was developed in 2007 and derives robust, IAE minimizing, PID controllers. The experiences of using this software are collected in this article and include
We present parameterized algorithms for the k-path problem, the p-packing of q-sets problem, and the q-dimensional p-matching problem. Our algorithms solve these problems with high probability in time exponential only in the parameter (k, p, q) and using polynomial space. The constant bases of the exponentials are significantly smaller than in previous works; for example, for the k-path problem th
III-V compound semiconductors are used in, among many other things, high-frequency electronics. They are also considered as a replacement for silicon in CMOS technology. Yet, a III-V transistor outperforming state-of-the-art silicon devices in VLSI-relevant metrics has not yet decisively been demonstrated. In this work, the limits of III-V FET performance, for both RF and VLSI applications, are ex
As more people move to cities and urban areas are growing, demand for urban transport increases. This leads not only to pressure on sustainability and climate goals, but also on the attractiveness and liveability of urban areas. Thus, it is necessary to decrease the use of private cars and create a modal shift towards more sustainable modes of transport, such as walking, cycling and public transpo
Ischemic stroke is a leading cause of death and disability worldwide. Currently, there is no treatment that can promote recovery in the chronic phase. It has been shown that neurogenesis occurs in ischemic striatum in rodents and probably also in humans. Moreover, blood-borne macrophages have been found to enhance spontaneous post- stroke recovery in mice. These findings have suggested potentia
