description: A common view in evolutionary biology is that mutation rates are minimised. However, studies in combinatorial optimisation and search have shown a clear advantage of using variable mutation rates as a control parameter to optimise the performance of evolutionary algorithms. Much biological theory in this area is based on Ronald Fisher's work, who used Euclidean geometry to study the relation between mutation size and expected fitness of the offspring in infinite phenotypic spaces. Here we reconsider this theory based on the alternative geometry of discrete and finite spaces of DNA sequences. First, we consider the geometric case of fitness being isomorphic to distance from an optimum, and show how problems of optimal mutation rate control can be solved exactly or approximately depending on additional constraints of the problem. Then we consider the general case of fitness communicating only partial information about the distance. We define weak monotonicity of fitness landscapes and prove that this property holds in all landscapes that are continuous and open at the optimum. This theoretical result motivates our hypothesis that optimal mutation rate functions in such landscapes will increase when fitness decreases in some neighbourhood of an optimum, resembling the control functions derived in the geometric case. We test this hypothesis experimentally by analysing approximately optimal mutation rate control functions in 115 complete landscapes of binding scores between DNA sequences and transcription factors. Our findings support the hypothesis and find that the increase of mutation rate is more rapid in landscapes that are less monotonic (more rugged). We discuss the relevance of these findings to living organisms.

description: In this work, we derived a semiclassical approximation for the matrix elements of a quantum propagator in coherent states (CS) basis that avoids complex trajectories, it only involves real ones. For that propose, we used the, symplectically invariant, semiclassical Weyl propagator obtained by performing a stationary phase approximation (SPA) for the path integral in the Weyl representation. After what, for the transformation to CS representation SPA is avoided, instead a quadratic expansion of the complex exponent is used. This procedure also allows to express the semiclassical CS propagator uniquely in terms of the classical evolution of the initial point, without the need of any root search typical of Van Vleck Gutzwiller based propagators. For the case of chaotic Hamiltonian systems, the explicit time dependence of the CS propagator has been obtained. The comparison with a \textquotedbl{}realistic\textquotedbl{} chaotic system that derives from a quadratic Hamiltonian, the cat map, reveals that the expression here derived is exact up to quadratic Hamiltonian systems.

description: Controlling the coupling between localized spins and itinerant electrons can lead to exotic magnetic states. A novel system featuring local magnetic moments and extended 2D electrons is the interface between LaAlO3 and SrTiO3. The magnetism of the interface, however, was observed to be insensitive to the presence of these electrons and is believed to arise solely from extrinsic sources like oxygen vacancies and strain. Here we show the existence of unconventional electronic phases in the LaAlO3/SrTiO3 system pointing to an underlying tunable coupling between itinerant electrons and localized moments. Using anisotropic magnetoresistance and anomalous Hall effect measurements in a unique in-plane configuration, we identify two distinct phases in the space of carrier density and magnetic field. At high densities and fields, the electronic system is strongly polarized and shows a response, which is highly anisotropic along the crystalline directions. Surprisingly, below a density-dependent critical field, the polarization and anisotropy vanish whereas the resistivity sharply rises. The unprecedented vanishing of the easy axes below a critical field is in sharp contrast with other coupled magnetic systems and indicates strong coupling with the moments that depends on the symmetry of the itinerant electrons. The observed interplay between the two phases indicates the nature of magnetism at the LaAlO3/SrTiO3 interface as both having an intrinsic origin and being tunable.

      Silicium-Komplexe können verwendet werden, um mit DNA-Duplexe

description: My work mainly includes two parts,
      one is GNA as a scaffold for molecular aggregates of
      chromophores, and the other one is the design of octahedral
      silicon complexes as DNA binders. In the first part of the
      thesis, simplified glycol nucleic acid (GNA) was used as the
      template for the helical assembly of covalently bound
      homochromophores and heterochromophores: perylene bisimide
      (B), phthalocyanine (Y), and porphyrin (P), and different
      numbers of chromophores could be stacking inside a duplex
      which led to functional artificial double-helical structures.
      In the second part of the thesis, the first examples of
      biologically active complexes based on octahedral silicon
      were designed, and silicon complexes with simple arenediol
      ligands and phenazinediol ligands were successfully
      synthesized. These kinds of siliconcomplexes could be used to
      intercalate with DNA duplexes, detect mismatched DNA base
      pairs, and stabilize the formation of the G-

description: In this thesis, some methods for
      the asymmetric synthesis of octahedral metal complexes were
      developed by using chiral auxiliaries. These chiral
      auxiliaries are coordinating bidentate ligands which control
      the metal-centered configuration in the course of ligand
      exchange reactions or dynamic equilibria. Afterwards, the
      chiral auxiliaries can be removed in an acid-induced fashion
      under complete retention of configuration. Additionally, we
      initially explored the applications of enantiomerically pure
      octahedral iridium complexes as catalysts for asymmetric
      transformations. In this direction, we focused on the
      asymmetric acyl transfer catalysis and synthesized different
      types of the catalysts for resolving racemic
      alcohols.

      zweizähnige Liganden, die bei Koordination die Konfiguration
      des Metallzentrums durch Ligandenaustausch- Reaktion oder
      dynamisches Gleichgewicht kontrollieren. Die chiralen
      Auxiliare können anschließend unter sauren Bedingungen
      abgespalten werden, wobei die Konfiguration des
      Metallzentrums erhalten bleibt Desweiteren wurden Anwendungen
      enantiomerenreiner Iridium-Komplexe für die asymmetrische
      Katalyse erforscht. Es wurde sich auf die asymmetrische
      Acyltransfer- Katalyse konzentriert. Verschiedene
      Katalysatoren wurden synthetisiert und für die kinetische
      Racematspaltung sekundärer Alkohole untersucht.

description: We describe a many-body quantum system which can be made to quantum compute by the adiabatic application of a large applied field to the system. Prior to the application of the field quantum information is localized on one boundary of the device, and after the application of the field this information has propagated to the other side of the device with a quantum circuit applied to the information. The applied circuit depends on the many-body Hamiltonian of the material, and the computation takes place in a degenerate ground space with symmetry-protected topological order. Such adiabatic quantum transistors are universal adiabatic quantum computing devices which have the added benefit of being modular. Here we describe this model, provide arguments for why it is an efficient model of quantum computing, and examine these many-body systems in the presence of a noisy environment.

description: We introduce a variational principle for field theories, referred to as the Hamilton-Pontryagin principle, and we show that the resulting field equations are the Euler-Lagrange equations in implicit form. Secondly, we introduce multi-Dirac structures as a graded analog of standard Dirac structures, and we show that the graph of a multisymplectic form determines a multi-Dirac structure. We then discuss the role of multi-Dirac structures in field theory by showing that the implicit Euler-Lagrange equations for fields obtained from the Hamilton-Pontryagin principle can be described intrinsically using multi-Dirac structures. Lastly, we show a number of illustrative examples, including time-dependent mechanics, nonlinear scalar fields, Maxwell's equations, and elastostatics.

description: In this paper, we present a new adaptive feature scaling scheme for ultrahigh-dimensional feature selection on Big Data. To solve this problem effectively, we first reformulate it as a convex semi-infinite programming (SIP) problem and then propose an efficient \emph{feature generating paradigm}. In contrast with traditional gradient-based approaches that conduct optimization on all input features, the proposed method iteratively activates a group of features and solves a sequence of multiple kernel learning (MKL) subproblems of much reduced scale. To further speed up the training, we propose to solve the MKL subproblems in their primal forms through a modified accelerated proximal gradient approach. Due to such an optimization scheme, some efficient cache techniques are also developed. The feature generating paradigm can guarantee that the solution converges globally under mild conditions and achieve lower feature selection bias. Moreover, the proposed method can tackle two challenging tasks in feature selection: 1) group-based feature selection with complex structures and 2) nonlinear feature selection with explicit feature mappings. Comprehensive experiments on a wide range of synthetic and real-world datasets containing tens of million data points with $O(10^{14})$ features demonstrate the competitive performance of the proposed method over state-of-the-art feature selection methods in terms of generalization performance and training efficiency.

description: The aim of this paper is to develop a mathematical framework for opto-elastography. In opto-elastography, a mechanical perturbation of the medium produces a decorrelation of optical speckle patterns due to the displacements of optical scatterers. To model this, we consider two optically random media, with the second medium obtained by shifting the first medium in some local region. We derive the radiative transfer equation for the cross-correlation of the wave fields in the media. Then we derive its diffusion approximation. In both the radiative transfer and the diffusion regimes, we relate the correlation of speckle patterns to the solutions of the radiative transfer and the diffusion equations. We present numerical simulations based on our model which are in agreement with recent experimental measurements.
Duplicial algebras and Lagrange inversion

description: We provide operadic interpretations for two Hopf subalgebras of the algebra of parking functions. The Catalan subalgebra is identified with the free duplicial algebra on one generator, and the Schröder subalgebra is interpreted by means of a new operad, which we call triduplicial. The noncommutative Lagrange inversion formula is then interpreted in terms of duplicial structures. The generic solution of the noncommutative inversion problem appears as the formal sum of all parking functions. This suggests that combinatorial generating functions derived by functional inversion should be obtainable by evaluating a suitable character on this generic solution. This idea is illustrated by means of the Narayana polynomials, of which we obtain bivariate "super-analogues" by lifting to parking functions a classical character of the algebra of symmetric functions. Other characters, such as evaluation of symmetric functions on a binomial element, are also discussed.

description: A central biological question is how natural organisms are so evolvable (capable of quickly adapting to new environments). A key driver of evolvability is the widespread modularity of biological networks--their organization as functional, sparsely connected subunits--but there is no consensus regarding why modularity itself evolved. While most hypotheses assume indirect selection for evolvability, here we demonstrate that the ubiquitous, direct selection pressure to reduce the cost of connections between network nodes causes the emergence of modular networks. Experiments with selection pressures to maximize network performance and minimize connection costs yield networks that are significantly more modular and more evolvable than control experiments that only select for performance. These results will catalyze research in numerous disciplines, including neuroscience, genetics and harnessing evolution for engineering purposes.
Dark energy from conformal symmetry breaking

description: The breakdown of conformal symmetry in a conformally invariant scalar-tensor gravitational model is revisited in the cosmological context. Although the old scenario of conformal symmetry breaking in cosmology containing scalar field has already been used in many earlier works, it seems that no special attention has been paid for the investigation on the possible connection between the breakdown of conformal symmetry and the existence of dark energy. In this paper, it is shown that the old scenario of conformal symmetry breaking in cosmology, if properly interpreted, not only has a potential ability to describe the origin of dark energy as a symmetry breaking effect, but also may resolve the coincidence problem.

description: In dieser Arbeit wurde eine
      konventionelle RT-PCR für die wichtigsten nosokomial
      übertragbaren hämorrhagische Fieber auslösenden Viren
      (Marburg-, Ebola-, Lassa-, Krim-Kongo Hämorrhagisches Fieber
      Virus) mit einer real-time RT-PCR auf dem Roche LightCycler
      verglichen. Dabei zeigte sich, dass die konventionelle RT-PCR
      der real-time RT-PCR in Punkto Sensitivität und Performance
      deutlich überlegen ist. Es konnte gezeigt werden, dass die
      konventionelle RT-PCR ein hoch-sensitives Verfahren ist, bei
      dem sich zudem die Richtigkeit des Ergebnisses durch die
      Integrierung einer internen Kontrolle ohne
      Sensitivitätsverlust verifizieren lässt. Außerdem wurden die
      RT-PCR Protokolle so ausgelegt, dass sie gleichzeitig in
      einem PCR-Cycler laufen können. Des Weiteren wurde getestet,
      ob die Reaktionsansätze für die Multiplex RT-PCR zur
      Komplettierung vorpipettiert für ihren Einsatz bereit
      gehalten werden können. Die Funktionalität konnte für
      mindestens ein Jahr sichergestellt werden.
description: Haemorrhagic fevers are caused by
      a wide range of viruses. Some of them are known to spread
      easily by person to person contact and are able to cause
      nosocomial infections with high fatality rates. This applies
      especially to arenaviruses (Lassa fever and more
      exceptionally the Junin and Machupo vi-rus), a bunyavirus
      (Crimean-Congo haemorrhagic fever) and the Filoviridae (Ebola
      and Marburg viruses). Because these diseases occur initially
      with non-specific influenza-like symptoms like fever,
      headache, myalgia etc. clinical dia-gnosis can be difficult.
      Therefore a quick, sensitive and specific diagnostic me-thod
      is needed to confirm or rule out infection. Since the viruses
      are endemic in developing countries the method should also be
      as cheap as possible. The Re-verse-Transcription PCR combines
      these characteristics best. In this thesis RT-PCR protocols
      were developed that were used to detect all viruses mentioned
      above in one single run (except Ebola-bundibugyo which was
      discovered after the practical part). An internal control was
      implemented to minimize the risk of false-negative
      results.

description: Im Rahmen dieser kumulativen
      Doktorarbeit werden Studien mit sichtbarem Licht und
      Terahertzlicht an Halbleiter-Quantenfilmen beschrieben, wobei
      Experimente mit Hilfe einer mikroskopischen Theorie
      analysiert werden. Nach einer Einleitung in Kapitel 1 werden
      die theoretischen Grundlagen in Kapitel 2 dargelegt. Hiernach
      folgt die Beschreibung von zwei Arten von Experimenten: In
      Kapitel 3 wird Terahertzspektroskopie an Quantenfilmen
      beschrieben, bei denen das sichtbare Licht in erster Linie
      mit den Quantenfilmen wechselwirkt. In Kapitel 4 besteht
      zusätzlich eine starke Kopplung des sichtbaren Lichtes mit
      einer Kavität. Beide Themen sind aufgrund der Ähnlichkeiten
      von Exzitonen mit atomaren Systemen von grundsätzlichem
      Interesse. Ein sehr fundamentaler Effekt, der beide Themen
      verbindet, ist der AC-Stark-Effekt: Er beschreibt das
      Aufspalten von Spektrallinien durch die Anwesenheit eines
      elektrischen Feldes. In Atomen wird dies Rabiaufspaltung
      genannt. Kapitel 3 beschreibt Experimente mit
      terahertzinduzierter Rabiaufspaltung. In Kapitel 4 wird
      Terahertzspektroskopie an Exziton-Polaritonen beschrieben.
      Diese entstehen, wenn Quantenfilme an eine Kavität koppeln.
      Die 1s-Exzitonenresonanz spal- tet auf in tiefere und höhere
      Exziton-Polaritonen. Eine Zusammenfassung und ein Ausblick
      werden in Kapitel 5 gegeben.
description: In this Thesis, studies with
      optical and terahertz light on semiconductor quantum wells
      are presented. Experiments are analyzed by means of a
      microscopic theory. A short introduction in chapter 1 is
      followed by the theoretical basis in chapter 2. After, two
      kinds of experiments are shown: Chapter 3 is devoted to
      terahertz spectroscopy on bare quantum wells. In chapter 4,
      the optical light couples in addition to a micro cavity. Both
      topics are of fundamental interest due to the similarity of
      excitons with atomic systems. A basic effect connecting both
      topics is the AC Stark effect: It describes the splitting of
      spectral lines due to the presence of an electric field. For
      atomic systems, this is called Rabi splitting. Chapter 3
      describes experiments with terahertz-induced Rabi splitting.
      In chapter 4, terahertz spectroscopy on exciton-polaritons is
      described. These appear due to the coupling of the quantum
      wells to a micro cavity: The 1s-exciton resonance splits into
      lower and higher exciton-polaritons. Concluding remarks and a
      short outlook are given in chapter 5.

Droplet microfluidics to prepare magnetic polymer vesicles and to confine the heat in magnetic hyperthermia

description: In this work, we present two types of microfluidic chips involving magnetic nanoparticles dispersed in cyclohexane with oleic acid. In the first case, the hydrophobically coated nanoparticles are self-assembled with an amphiphilic diblock copolymer by a double-emulsion process in order to prepare giant magnetic vesicles (polymersomes) in one step and at a high throughput. It was shown in literature that such diblock copolymer W/O/W emulsion droplets can evolve into polymersomes made of a thin (nanometric) magnetic membrane through a dewetting transition of the oil phase from the aqueous internal cores usually leading to "acorn-like" structures (polymer excess) sticking to the membranes. To address this issue and greatly speed up the process, the solvent removal by evaporation was replaced by a "shearing-off" of the vesicles in a simple PDMS chip designed to exert a balance between a magnetic gradient and viscous shear. In the second example, a simple oil-in-oil emulsion chip is used to obtain regular trains of magnetic droplets that circulate inside an inductor coil producing a radio-frequency magnetic field. We evidence that the heat produced by magnetic hyperthermia can be converted into a temperature rise even at the scale of nL droplets. The results are compared to heat transfer models in two limiting cases: adiabatic vs. dissipative. The aim is to decipher the delicate puzzle about the minimum size required for a tumor "phantom" to be heated by radio-frequency hyperthermia in a general scope of anticancer therapy.

External Tonehole Interactions in Woodwind Instruments

description: The classical Transfer-Matrix Method (TMM) is often used to calculate the input impedance of woodwind instruments. However, the TMM ignores the possible influence of the radiated sound from toneholes on other open holes. In this paper a method is proposed to account for external tonehole interactions. We describe the Transfer-Matrix Method with external Interaction (TMMI) and then compare results using this approach with the Finite Element Method (FEM) and TMM, as well as with experimental data. It is found that the external tonehole interactions increase the amount of radiated energy, reduce slightly the lower resonance frequencies, and modify significantly the response near and above the tonehole lattice cutoff frequency. In an appendix, a simple perturbation of the TMM to account for external interactions is investigated, though it is found to be inadequate at low frequencies and for holes spaced far apart.
title: Cultivating human beings, not human doings : challenging discourses of self care
Creators: name: Little, J. Nicole
Publisher: name: Strathprints - University of Strathclyde
Year: 2016

description: To what do we owe the project of human doings over human beings? Self-care has long been sanctioned as the root of Child and Youth Care (CYC) practitioner resilience. This argument is faulty in its individualistic and "doing" ways. Instead, the author proposes that we need to connect with vulnerability and love as a means to accomplish self and other-care. Critiquing contemporary discourses of self-care, the author draws on Buddhist philosophy and Radically Open Dialectical Behaviour Therapy (RO-DBT) as a means to deconstruct this.

Decoding billions of integers per second through vectorization

description: In many important applications -- such as search engines and relational database systems -- data is stored in the form of arrays of integers. Encoding and, most importantly, decoding of these arrays consumes considerable CPU time. Therefore, substantial effort has been made to reduce costs associated with compression and decompression. In particular, researchers have exploited the superscalar nature of modern processors and SIMD instructions. Nevertheless, we introduce a novel vectorized scheme called SIMD-BP128 that improves over previously proposed vectorized approaches. It is nearly twice as fast as the previously fastest schemes on desktop processors (varint-G8IU and PFOR). At the same time, SIMD-BP128 saves up to 2 bits per integer. For even better compression, we propose another new vectorized scheme (SIMD-FastPFOR) that has a compression ratio within 10% of a state-of-the-art scheme (Simple-8b) while being two times faster during decoding.
