1. Electrically evoked release of [3H]-noradrenaline ([3H]-NA) or [3H]-5-hydroxytryptamine ([3H]-5-HT) in slices of human and the rat neocortex was used to characterize presynaptic opioid receptors. 2. Release of [3H]-NA in rat neocortical slices was reduced only by the mu-receptor agonist DAMGO (pIC50: 7.27, CI95: [7.22, 7.32]; Imax: 77.6+/-1.6%;(More)
Augmenting probabilities to conditional logic yields an expressive mechanism for representing uncertainty. The principle of optimum entropy allows one to reason in probabilistic logic in an information-theoretic optimal way by completing the given information as unbiasedly as possible. In this paper, we introduce the MECoRe system that realises the core(More)
Keywords: Spectral geometry processing Vector bundles Computational topology Laplace operator Finite elements a b s t r a c t Computing the spectral decomposition of the Laplace–Beltrami operator on a manifold M has proven useful for applications such as shape retrieval and geometry processing. The standard operator acts on scalar functions which can be(More)
In the present work, we extend the theoretical and numerical discussion of the well-known Laplace–Beltrami operator by equipping the underlying manifolds with additional structure provided by vector bundles. Focusing on the particular class of flat complex line bundles, we examine a whole family of Laplacians including the Laplace–Beltrami operator as a(More)
BACKGROUND AND PURPOSE Patients with severe acute stroke are at high risk for systemic infections which are associated with an increase in morbidity and mortality; nevertheless current guidelines do not recommend prophylactic antibiotic therapy. Sensitive detection of pathogens in the blood is desirable to guide early antibiotic therapy. We studied the(More)
This publication is a contribution to basic research in image comparison using eigenvalue spectra as features. The differential-geometric approach of eigenvalue spectrum-based descriptors is naturally applicable to shape data, but so far little work has been done to transfer it to the setting of image data painted on a rectangle or general curved surface.(More)
A polyspecific, intrathecal humoral immune response against the neurotropic viruses, measles, rubella and varicella zoster virus, called “MRZ reaction” (MRZR), is present in the majority of patients with multiple sclerosis (MS). Neurosarcoidosis (NS) and acute disseminated encephalomyelitis (ADEM) are important clinical differential diagnoses of MS.(More)
Previous findings suggest an angiogenesis-regulating function of the p53 tumor suppressor protein in various malignancies. With several antiangiogenic agents entering the clinic, we assessed the value of the TP53 status in predicting angiogenesis in glioblastoma in vivo and examined underlying angiogenic-signaling pathways in vitro. We identified 26 TP53(More)
Designing soft robots is difficult, time-consuming, and non-intuitive. Soft robot design faces two main challenges: structure and control. This research uses generative encodings to grow structures and a vibrational mechanism to control locomotion. In this paper, we demonstrate the ability to successfully evolve soft robots that can move when vibrated. Soft(More)
OBJECTIVES Paraneoplastic neurological syndromes (PNSs) are rare disorders in association with cancer and sub-divided into "classical" and "non-classical" syndromes according to a 2004 consensus paper proposed by a panel of PNS experts. "Classical" PNSs are regarded to account for the vast majority of cases. However, systematic reports on clinical PNS(More)
