Abstract:
AbstractOn a theoretical basis, the possible relation is discussed between the ‘morphic resonance’ theory of Dr Rupert Sheldrake and its possible contribution to establishing homœopathy in a scientific frame. Sheldrake's hypotheses on ‘formative causation’ and morphic resonance initially influenced biological views on the processes of evolution and have been verified by psychological experiments.However, the theoretical background of Sheldrake's hypotheses may also be relevant to forming hypotheses on a yet unknown physical principle, which are to explain the working of homeopathic potencies.

Abstract:
We analyze the asymmetric delta-doping dependence of nonlinear electron mobility μ of GaAs|InxGa1-xAs double quantum-well pseudo-morphic modulation doped field-effect transistor structure. We solve the Schrodinger and Poisson's equations self-consistently to obtain the sub-band energy levels and wave functions. We consider scatterings due to the ionized impurities (IMP), alloy disorder (AL), and interface roughness (IR) to calculate μ for a system having double sub-band occupancy, in which the inter-sub-band effects play an important role. Considering the doping concentrations in the barriers towards the substrate and surface sides as Nd1 and Nd2, respectively, we show that variation of Nd1 leads to a dip in μ near Nd1=Nd2, at which the resonance of the sub-band states occurs. A similar dip in μ as a function of Nd1 is also obtained at Nd1=Nd2 by keeping (Nd1+Nd2) unchanged. By increasing the central barrier width and well width, the dip in μ becomes sharp. We note that even though the overall μ is governed by the IMP- and AL-scatterings, the dip in μ is mostly affected through substantial variation of the sub-band mobilities due to IR-scattering near the resonance. Our results of nonlinear electron mobility near the resonance of sub-band states can be utilized for the performance analysis of GaAs|InGaAs pseudo-morphic quantum-well field-effect transistors. Keywords: asymmetric double quantum wells, GaAs|InxGa1-xAs structures, nonlinear electron mobility, pseudo-morphic HEMT structures, resonance of sub-band states.

Abstract:
Der Fluoreszenz-Resonanz-Energie-Transfer ist ein Phänomen, welches erstmals 1948 von Theodor Förster beschrieben wurde. Mit der Entwicklung von Fluoreszenzproteinen konnten in Kombination mit Mikroskopietechniken Einblicke in zellbiologische Vorgänge gewonnen werden, die durch biochemische oder physiologische Experimente nicht möglich sind. Dabei spielt die hohe zeitliche und räumliche Auflösung eine wichtige Rolle. Auf dem Forschungsgebiet der GPCR, welche die größte Gruppe von Membranproteinen bei den Säugetieren darstellen, wurden insbesondere Erkenntnisse über Konformationsänderungen der Rezeptoren, die Kinetik der Rezeptoraktivierung und die Interaktion mit intrazellulären Signalproteinen gewonnen. Der µ-Opioidrezeptor gehört zur Familie der GPCR und stellt aufgrund seiner analgetischen Wirkungen eine wichtige pharmakologische Zielstruktur dar. Das Ziel dieser Arbeit war sowohl den Rezeptor als auch seine Signalwege mittels FRET-Mikroskopie zu untersuchen. Zunächst sollte ein intramolekularer FRET-Sensor des µ-Opioidrezeptors entwickelt werden, dazu wurden basierend auf den Kenntnissen über die Tertiärstruktur und dem Aufbau bereits bekannter GPCR-Sensoren verschiedene Rezeptorkonstrukte kloniert. Bei den Konstrukten wurden entweder zwei Fluoreszenzproteine oder ein Fluoreszenzprotein und ein Fluorophor-bindendes Tetracysteinmotiv kombiniert. Auch die Positionen der eingefügten Sequenzen wurden in den intrazellulären Domänen variiert, da der Rezeptor auf die Modifikationen mit beeinträchtigter Membranlokalisation reagierte. Durch die Optimierung wurden Rezeptoren konstruiert, die an der Zellmembran lokalisiert waren. Jedoch zeigte keines der Rezeptorkonstrukte Funktionalität im Hinblick auf die Rezeptoraktivierung. Im zweiten Teil wurden die pharmakologischen Effekte der Metabolite von Morphin am humanen µ-Opioidrezeptor systematisch analysiert. Dazu wurde die Fähigkeit der Metabolite, Gi-Proteine zu aktivieren und β-Arrestin2 zu rekrutieren, mittels FRET-basierter Messungen an lebenden Zellen untersucht. Außerdem wurde die Affinität der Metabolite zum humanen µ Opioidrezeptor anhand der Verdrängung eines radioaktiven Liganden analysiert. Meine Experimente identifizierten eine Gruppe mit stark agonistischen und eine mit schwach agonistischen Eigenschaften. Die starken Partialagonisten aktivieren den Rezeptor bereits bei nanomolaren Konzentrationen, während die schwachen Metabolite den Rezeptor erst bei Konzentrationen im mikromolaren Bereich aktivieren. Die Metabolite Normorphin, Morphin-6-Glucuronid und 6-Acetylmorphin zeigen geringere Potenz als Morphin bei der Gi-Aktivierung aber überraschenderweise höhere Potenz und Effizienz für die β-Arrestin-Rekrutierung. Dies deutet auf eine bevorzugte Aktivierung von β-Arrestin2 hin. Die aus diesen Studien gewonnenen Ergebnisse liefern Hinweise darauf, welche Metabolite bei der Signalverarbeitung am µ Opioidrezeptor in vivo beteiligt sind
Fluorescence resonance energy transfer was first described by Theodor Förster in 1948. The discovery and development of intrinsic fluorescent proteins revolutionized cell and molecular biology. The FRET-technique allows the analysis of protein-protein interactions and intramolecular conformational changes. In this method, its high temporal and spatial resolution plays a crucial role. Especially in the research field of GPCR, which are the largest family of membrane proteins in mammals, insights into receptor conformational changes, kinetics of receptor activation and the interaction with intracellular proteins were obtained. The µ-opioid receptor belongs to the GPCR family and is involved in analgesia. Therefore, the receptor is an important pharmacological target. Its pharmacological properties were extensively analyzed in the current thesis by FRET. Engineering of an intramolecular MOR-biosensor was initially planned. Based on the knowledge about the tertiary receptor structure and earlier GPCR-sensors, different receptor constructs were cloned. For each receptor construct either two fluorescent proteins or one fluorescent protein and one fluorophore binding tetracysteine motif were combined. The insertion of the additional amino acid sequences prevented the membrane localization for some constructs. Hence, the insertion site of the amioacid sequences was varied in the intracellular loops. Ultimately, the optimization resulted in some membrane localized receptor constructs with the tetracysteine motif in the third intracellular loop. Nevertheless, none of the receptor constructs was functional in terms of measurable conformational change upon receptor activation. In the second part of this thesis, the pharmacological effects of morphine and its metabolites were studied. The analgesic effects of morphine are mainly mediated via the activation of the µ opioid receptor. This receptor activates inhibitory G-proteins and induces the recruitment of β-arrestin2. Therefore I analyzed activation of these two pathways induced by morphine metabolites using FRET-microscopy in living cells. Furthermore, radioligand binding studies were used to determine the affinity of each compound to the human µ-opioid receptor. This approach identified two groups of metabolites, which were classified into strong and weak ligands. Strong partial agonists showed efficacies in the nanomalar range. In contrast, weak metabolites activated µ opioid receptor pathways in the micromolar range. Normorphine, morphine-6-glucuronide and 6 acetylmorphine had lower potencies regarding Gi-protein activation but higher potencies and efficacies for β-arrestin2 recruitment than morphine. These findings indicate that these metabolites are biased towards β-arrestin2 pathways

Abstract:
The texts examined in Chapter 4 explore islands in geo(morpho)logical space-time. The chapter begins by discussing how the relational poetics of Darwin’s and Wallace’s writings ask readers to reimagine planetary space as a discontinuous multiplicity of shifting islands. The notion of a geopoetic resonance between the material energies of the physical world and the poetic energies of language guides the analyses of three literary responses to Darwin, Wallace, and their successors. H. G. Wells’s The Island of Doctor Moreau (1896) and ‘Aepyornis Island’ (1894) figure islands as beleaguered territories haunted by the spectre of human extinction. However, their geopoetic descriptions of volcanism and coral suspend these evolutionary narratives. A century later, Amitav Ghosh’s The Hungry Tide explores the radical poetic implications of Darwin and Wallace’s archipelagic thinking. In the novel, the human element intersects with other living forms, physical geography, and textual spaces to form a mutable landscape shaped by conflicts.

Abstract:
Visual and auditory processes represent sensory information, but do not evaluate its importance for survival or success. Interactions between perceptual/cognitive and evaluative reinforcement/emotional/motivational mechanisms accomplish this. Cognitive-emotional resonances support conscious feelings, knowing their source, and controlling motivation and responses to acquire valued goals. Also explained is how emotions may affect behavior without being conscious, and how learning adaptively times actions to achieve desired goals. Breakdowns in cognitive-emotional resonances can cause symptoms of mental disorders such as depression, autism, schizophrenia, and ADHD, including explanations of how affective meanings fail to organize behavior when this happens. Historic trends in the understanding of cognition and emotion are summarized, including work of Chomsky and Skinner. Brain circuits of conditioned reinforcer learning and incentive motivational learning are modeled, including the inverted-U in conditioning as a function of interstimulus interval, secondary conditioning, and attentional blocking and unblocking. How humans and animals act as minimal adaptive predictors is explained using the CogEM model’s interactions between sensory cortices, amygdala, and orbitofrontal cortex. Cognitive-emotional properties solve phylogenetically ancient Synchronization and Persistence Problems using circuits that are conserved between mollusks and humans. Avalanche command circuits for learning arbitrary sequences of sensory-motor acts, dating back to crustacea, increase their sensitivity to environmental feedback as they morph over phylogeny into mammalian cognitive and emotional circuits. Antagonistic rebounds drive affective extinction. READ circuits model how life-long learning occurs without associative saturation or passive forgetting. Affective memories of opponent emotions like fear vs. relief can then persist until they are disconfirmed by environmental feedback.

Abstract:
Arrhythmogenic cardiomyopathy (AC) is a rare non-ischaemic cardiomyopathy with a prevalence in of 1:200 to 1:5000. In the 1980s, the disorder was demonstrated to be a major cause of sudden death (SD) in the young and athletes, thus emphasizing the need for early diagnosis for disqualification from sport activity. Pre-participation screening using ECG is effective in detecting ECG abnormalities which raise suspicion of the disease, requiring additional second- and third-level investigations to obtain a definite diagnosis. Cardiac magnetic resonance (CMR), which can detect both morpho-functional and tissue abnormalities, is probably the best tool for assessing doubtful cases. The rarer left ventricular variant (‘non-ischaemic left ventricular scar’) is not detected by ECG at first-level pre-participation screening, which presents a major challenge for SD prevention. Risk stratification consensus criteria recommend use of an implantable cardioverter defibrillator (ICD). Use of pre-participation screening and automated external defibrillators (AEDs), working together should help to prevent SD. Since at least 60% of cases are heredofamilial and usually present desmosome gene mutations, genetic investigation should be carried out in the proband and cascade genetic screening should be offered to first-degree family members for primary prevention. Basic research into the AC pathogenic mechanisms is in progress, and there is clinical and experimental evidence that exercise with right ventricular overload may favour onset and progression of AC, at least in genotype-positive patients. Reduction of sports activity will not only prevent abrupt onset of ventricular arrhythmias with the risk of SD, but may also delay phenotype expression.

Abstract:
Abstract Principal parametric resonances of elastic plates actuated by periodic in-plane stresses effected by embedded piezoelectric wires are investigated to describe the morphing scenarios of flexible, ultra-lightweight panels. A mechanical model of elastic plate including geometric nonlinearities and the parametric actuation provided by the piezoelectric wires, is adopted to formulate the nonlinear equation of motion. A bifurcation analysis is carried out by means of an asymptotic approach based on the method of multiple scales leading to a comprehensive parametric study on the effect of the wires width on the morphing regions (i.e., parametric instability regions) associated with the principal parametric resonances. The threshold voltages triggering the onset of the principal parametric resonances of the lowest three symmetric modes are also calculated as a function of the wires size so as to determine the voltage requirements for the morphing activation.

Abstract:
It is often important, for diagnostic purposes, to evaluate quantitatively the motion undergone by a biological structure, starting from a viable tomographic imaging technique, such as Computed Tomography (CT) or Magnetic Resonance (MR). This is often associated with the need of the clinical personnel to perform an evaluation of a risk factor associated with pathology, e.g. ventricle performance [1]. As of today, the problem has been approached by using the magnetic resonance (MR) tagging technique [2] or experimentally by determining the location of a series of surgically implanted markers in each temporal phase [3]. The latter procedure is naturally very invasive, while MR tagging requires the use of sophisticated MR sequences that are rarely employed in standard care. Multi-detector row computer tomography (CT) scanners (routinely used in cardiac pathology diagnosis) as well as routine cine-MR sequences, on the other hand, allow dynamic imaging of the heart and large vessels with cardiac gating. In order to exploit these dynamic sequences, we have developed a tag-less method to estimate local strains from dynamic tomography gated images.

Abstract:
The paper proposes a numerical approach for the analysis of the blood flow in human aorta under real operating conditions. An ad-hoc procedure is developed for importing the aorta geometry from magnetic resonance imaging in order to have a patient based analysis. The aortic flow is simulated accounting for the dynamic behavior of the flow resulting from the heart pulse and for the non-Newtonian properties of blood. Fluid – structure analysis is carried out to address the mutual influence of the flow transient nature and the aorta walls’ deformation on the pressure flow field and tissue’s stresses. Finite element method approach is used for the structural analysis of the aorta walls which are assumed as a linear elastic isotropic material; nevertheless, different regions are introduced to account for the Young modulus variation from the ascending aorta to the common iliac arteries. Mesh morphing techniques are adopted to simulate the wall deformation and a two equation turbulence model is adopted to include the turbulence effects. The proposed numerical approach is validated against the measurements carried out on magnetic resonance imaging scanner and a good agreement is found in terms of aorta wall maximum and minimum deformation during the cardiac cycle. Therefore, the fluid-structure analysis can provide an important tool to extend the insight of the aortic system from magnetic resonance imaging techniques and improve the understanding of arteriosclerosis and the related phenomena as well as their dependence on flow structure and tissue stresses.

Abstract:
The vortex street is a unique type of unsteady flow separation seen commonly in flow over a bluff body with a characteristic periodic wake. A consequence of the periodic flow is that the drag and lift forces acting on the body also oscillate periodically. When the wake shedding frequency is near a structural frequency, flow induced resonance will occur. The continuing interest in the study of vortex street generation is propelled by the ever-present nature of these flows in a variety of applications including aerodynamics, hydrodynamics and underwater acoustics. Recent advances in material science and the development of high power density actuators have led to the study of adaptive structure technology wherein the vorticity of periodic flows can be actively controlled by changing the ‘bluffness’ or shape of the body. In this paper, the development and experimental testing of a two-dimensional shape-variable flow control surface are discussed in relation to the generation and manipulation of periodic flow separation. Two series of wind tunnel tests were designed to evaluate the potential of the morphing structure that replaced a section of the trailing edge of a symmetric airfoil. The test section successfully demonstrated a smooth transition between three prescribed trailing edge profiles ranging from sharp to blunt. Unsteady pressure spectra were measured near the trailing edge for three different shape profiles over a range of speeds between 50 and 110 ft/s. The measured pressure spectra amplitudes were compared to previously-published surface pressure spectra of a similar, two-dimensional, blunt edge foil. A second set of tests was performed to measure the resulting flow field in the direction transverse to the flow and downstream from the airfoil. Velocity measurements were made using a traversing hot-wire probe at three trailing edge configurations and speeds of 50, 70 and 90 ft/s. The corresponding Reynolds number based on wake thickness ranged from 3.9–9.8 × 104. Measured vortex shedding frequencies varied between approximately 50 to 130 Hz at the different trailing edge profiles. This type of change in the vortex shedding frequency can be used to reduce flow-induced vibration and its associated noise generation by avoiding shedding frequencies at operating speeds that coincide with airfoil resonances.
