description: A pp-wave solution to 11-dimensional supergravity is given with precisely 26 supercharges. Its uniqueness and the absence of 11-dimensional pp-waves which preserve (precisely) 28 or 30 supercharges is discussed. Compactification on a spacelike circle gives a IIA configuration with all 26 of the supercharges. For this compactification, D0 brane charge does not appear in the supersymmetry algebra. Indeed, the 26 supercharge IIA background does not admit any supersymmetric D-branes. In an appendix, a 28 supercharge IIB pp-wave is presented along with its supersymmetry algebra.

description: Using micro level data from Cameroon this paper applies the theories of intrahousehold bargaining to models in which female farmers decide whether to take up cocoa marketing on their own or to rely on others to sell the product. We analyze the effect of marketing on control over the proceeds. We find that controlling both production and marketing provides higher bargaining power over proceeds compared to a situation in which the farmer participates only in production and delegate the task of marketing to another family member. Our data also indicate that in the cocoa sector of Cameroon, female farmers’ market participation is hindered by existing price discrimination, which in turn reduces their intrahousehold bargaining power. In other words, participating female farmers receive much lower prices for their produce than participating males. To generate higher revenue, female farmers hand over the marketing responsibility to a male in the family. Such non-participation results in lower control over the proceeds by the female farmer, as the individual doing the marketing can now claim a higher share in the revenue. Additionally we find that collective marketing contributes to eliminating price discrimination and promoting female market participation and thus their control over proceeds.

description: The interdisciplinary study of the flow of energy-matter-information in cardiac electrophysiology from the mathematical perspective and computational simulation, allowed to demonstrate characteristic aspects of complexity sciences and complex systems, such as non-linear dynamics, sensitivity of initial-conditions, autoorganization in non-equilibrium systems and emergence of patterns. This is particularly notable when considering a non-isotropic excitable medium, as occurs with the propagation and activation of electrical impulses in the heart, whose fibers not only change their orientation altering the speed depending on the thickness of the epicardium, myocardium and endocardium, but also present the properties of excitability, conductance, automatism, contractility and relaxation in the description of the normal and abnormal functioning of the heart when pumping blood to drive oxygen and other nutrients to tissues, remove waste products and transport substances, such as hormones, from one part of the body to another.The objectives of this thesis can be summarized in three main chapters: i) Introduction to the complexity sciences and complex systems from the physiological foundations of wave propagation in excitable media at cellular level and from anisotropic heart tissue; ii) Mathematical modeling of electrical activity with temporary dynamic systems, discrete and continuous models, such as automata and specific ionic models at the cellular level, and for cardiac tissue, with reaction-diffusion systems such as the bidomain and monodomain model, respectively; iii) Mathematical formulation of anisotropic conduction to perform simulations of electrophysiological models with code development in the Matlab® environment. Application software designed for the UACM Master’s Degree in Complexity Sciences and, analysis of international standards for the exchange of information between mathematical-computer models of the organisms components: organs, cellular systems, biochemical and endocrine systems.

description: We study the constraints on models with extra dimensions arising from local anomaly cancellation. We consider a five-dimensional field theory with a U(1) gauge field and a charged fermion, compactified on the orbifold S^1/(Z_2 x Z_2'). We show that, even if the orbifold projections remove both fermionic zero modes, there are gauge anomalies localized at the fixed points. Anomalies naively cancel after integration over the fifth dimension, but gauge invariance is broken, spoiling the consistency of the theory. We discuss the implications for realistic supersymmetric models with a single Higgs hypermultiplet in the bulk, and possible cancellation mechanisms in non-minimal models.

description: It has very recently been realized that coupling branes to higher dimensional quantum gravity theories and considering the consistency of what lives on the branes, one is able to understand whether such theories can belong either to the swampland or to the landscape. In this regard, in the present work, we study a warm inflation model embedded in the Randall-Sundrum braneworld scenario. It is explicitly shown that this model belongs to the landscape by supporting a strong dissipative regime with an inflaton steep exponential potential. The presence of extra dimension effects from the braneworld allow achieving this strong dissipative regime, which is shown to be both theoretically and observationally consistent. In fact, such strong dissipation effects, which decrease towards the end of inflation, together with the extra dimension effect, allow the present realization to simultaneously satisfy all previous restrictions imposed on such a model and to evade the recently proposed swampland conjectures. The present implementation of this model, in terms of an exponential potential for the scalar field, makes it also a possible candidate for describing the late-time Universe in the context of a dissipative quintessential inflation model and we discuss this possibility in the Conclusions.

description: We describe a quantum PAC learning algorithm for DNF formulae under the uniform distribution with a query complexity of $\tilde{O}(s^{3}/ε+ s^{2}/ε^{2})$, where $s$ is the size of DNF formula and $ε$ is the PAC error accuracy. If $s$ and $1/ε$ are comparable, this gives a modest improvement over a previously known classical query complexity of $\tilde{O}(ns^{2}/ε^{2})$. We also show a lower bound of $Ω(s\log n/n)$ on the query complexity of any quantum PAC algorithm for learning a DNF of size $s$ with $n$ inputs under the uniform distribution.

description: We study the LHC sensitivity to probe a long-lived heavy neutrino $N$ in the context of $Z'$ models. We focus on displaced vertex signatures of $N$ when pair produced via a $Z'$, decaying to leptons and jets inside the inner trackers of the LHC experiments. We explore the LHC reach with current long-lived particle search strategies for either one or two displaced vertices in association with hadronic tracks or jets. We focus on two well-motivated models, namely, the minimal $U(1)_{B-L}$ scenario and its $U(1)_{X}$ extension. We find that searches for at least one displaced vertex can cover a significant portion of the parameter space, with light-heavy neutrino mixings as low as $|V_{lN}|^2\approx 10^{-17}$, and $l=e,μ$ accessible across GeV scale heavy neutrino masses.

description: Motivated by experiments in electroconvection in nematic liquid crystals with homeotropic alignment we study the coupled amplitude equations describing the formation of a stationary roll pattern in the presence of a weakly-damped mode that breaks isotropy. The equations can be generalized to describe the planarly aligned case if the orienting effect of the boundaries is small, which can be achieved by a destabilizing magnetic field. The slow mode represents the in-plane director at the center of the cell. The simplest uniform states are normal rolls which may undergo a pitchfork bifurcation to abnormal rolls with a misaligned in-plane director.We present a new class of defect-free solutions with spatial modulations perpendicular to the rolls. In a parameter range where the zig-zag instability is not relevant these solutions are stable attractors, as observed in experiments. We also present two-dimensionally modulated states with and without defects which result from the destabilization of the one-dimensionally modulated structures. Finally, for no (or very small) damping, and away from the rotationally symmetric case, we find static chevrons made up of a periodic arrangement of defect chains (or bands of defects) separating homogeneous regions of oblique rolls with very small amplitude. These states may provide a model for a class of poorly understood stationary structures observed in various highly-conducting materials ("prechevrons" or "broad domains").

description: Despite the high technical relevance of early flame kernel development for the reduction of cycle-to-cycle variations in spark ignition engines, there is still a need for a better fundamental understanding of the governing in-cylinder phenomena in order to enable resilient early flame growth. To isolate the effects of small- and large-scale turbulent flow motion on the young flame kernel, a three-dimensional DNS database has been designed to be representative for engine part load conditions. The analysis is focussed on flame displacement speed and flame area in order to investigate effects of flame structure and flame geometry on the global burning rate evolution. It is shown that despite a Karlovitz number of up to 13, which is at the upper range of conventional engine operation, thickening of the averaged flame structure by small-scale turbulent mixing is not observed. After ignition effects have decayed, the flame normal displacement speed recovers the behavior of a laminar unstretched premixed flame under the considered unity-Lewis-number conditions. Run-to-run variations in the global heat release rate are shown to be primarily caused by flame kernel area dynamics. The analysis of the flame area balance equation shows that turbulence causes stochastic flame kernel area growth by affecting the curvature evolution, rather than by inducing variations in total flame area production by strain. Further, it is shown that in local segments of a fully-developed planar flame with similar surface area as the investigated flame kernels, temporal variations in flame area rate-of-change occur. Contrasting to early flame kernels, these effects can be exclusively attributed to curvature variations in negatively curved flame regions.

description: In this article we present a full description of the quantum Kerr Ising model---a linear optical network of parametrically pumped Kerr non-linearities. We consider the non-dissapative Kerr Ising model and, using variational techniques, show that the energy spectrum is primarily determined by the adjacency matrix in the Ising model and exhibits highly non-classical cat like eigenstates. We then introduce dissipation to give a quantum mechanical treatment of the measurement process based on homodyne detection via the conditional stochastic Schrodinger equation. Finally we identify a quantum advantage in comparison to the classical analogue for the example of two anti-ferromagnetic cavities.

Partial Optomechanical Refrigeration via Multimode Cold-Damping Feedback

description: We provide a fully analytical treatment for the partial refrigeration of the thermal motion of a quantum mechanical resonator under the action of feedback. As opposed to standard cavity optomechanics where the aim is to isolate and cool a single mechanical mode, the aim here is to extract the thermal energy from many vibrational modes within a large frequency bandwidth. We consider a standard cold-damping technique where homodyne read-out of the cavity output field is fed into a feedback loop that provides a cooling action directly applied on the mechanical resonator. Analytical and numerical results predict that low final occupancies are achievable independently of the number of modes addressed by the feedback as long as the cooling rate is smaller than the intermode frequency separation. For resonators exhibiting a few nearly degenerate pairs of modes cooling is less efficient and a weak dependence on the number of modes is obtained. These scalings hint towards the design of frequency resolved mechanical resonators where efficient refrigeration is possible via simultaneous cold-damping feedback.

A new Time-Of-Flight Mass Spectrometer (TOF-MS) for noble gas analysis

Publisher: name: Universität Bern
Year: 2015
Subjects: 530 Physics

description: Noble gas analysis in early solar system materials, which can provide valuable information about early solar system processes and timescales, are very challenging because of extremely low noble gas concentrations (ppt). We therefore developed a new compact sized (33 cm length, 7.2cm diameter, 1.3 L internal volume) Time-of-Flight (TOF) noble gas mass spectrometer for high sensitivity. We call it as Edel Gas Time-of-flight (EGT) mass spectrometer. The instrument uses electron impact ionization coupled to an ion trap, which allows us to ionize and measure all noble gas isotopes. Using a reflectron set-up improves the mass resolution. In addition, the reflectron set-up also enables some extra focusing. The detection is via MCPs and the signals are processed either via ADC or TDC systems. The objective of this work is to understand the newly developed Time-Of-Flight (TOF) mass spectrometer for noble gas analysis in presolar grains of the meteorites. Chapter 1 briefly introduces the basic idea and importance of the instrument. The physics relevant to time-of-flight mass spectrometry technique is discussed in the Chapter 2 and Chapter 3 will present the oxidation technique of nanodiamonds of the presolar grains by using copper oxide. Chapter 4 will present the details about EGT data analysis software. Chapter 5 and Chapter 6 will explain the details about EGT design and operation. Finally, the performance results will be presented and discussed in the Chapter 7, and whole work is summarized in Chapter 8 and also outlook of the future work is given.

description: In a recent Letter Bray and Blythe have shown that the survival probability P(t) of an A particle diffusing with a diffusion coefficient D_A in a 1D system with diffusive traps B is independent of D_A in the asymptotic limit t \to \infty and coincides with the survival probability of an immobile target in the presence of diffusive traps. Here we show that this remarkable behavior has a more general range of validity and holds for systems of an arbitrary dimension d, integer or fractal, provided that the traps are "compactly exploring" the space, i.e. the "fractal" dimension dw of traps' trajectories is greater than d. For the marginal case when dw = d, as exemplified here by conventional diffusion in 2D systems, the decay form is determined up to a numerical factor in the characteristic decay time.

description: Over the past few years it has been pointed out that direct inversion of accurate but approximate ground state densities leads to Kohn-Sham exchange-correlation (xc) potentials that can differ significantly from the exact xc potential of a given system. On the other hand, the corresponding wavefunction based construction of exchange-correlation potential as done by Baerends et al. and Staroverov et al. obviates such problems and leads to potentials that are very close to the true xc potential. In this paper, we provide an understanding of why the wavefunction based approach gives the exchange-correlation potential accurately. Our understanding is based on the work of Levy, Perdew and Sahni (LPS) who gave an equation for the square root of density (density amplitude) and the expression for the associated effective potential in the terms of the corresponding wavefunction. We show that even with the use of approximate wavefunctions the LPS expression gives accurate effective and exchange-correlation potentials. Based on this we also identify the source of difference between the potentials obtained from a wavefunction and those given by the inversion of the associated density. Finally, we suggest exploring the possibility of obtaining accurate ground-state density from an approximate wavefunction for a system by making use of the LPS effective potential.

description: In der vorliegenden Arbeit wurde die Sicherheit und Zuverlässigkeit der Nebenschilddrüsenchirurgie beim Hyperparathyreoidismus mit intraoperativer Bestimmung des intakten Parathormons (Parathormonschnelltest) untersucht. Im Zeitrahmen zwischen 1/2004 und 12/2008 wurden an der universitären Klinik für viszerale Chirurgie und Medizin bei 194 operierten Patienten 150 Adenome, 39 Hyperplasien, sowie 5 Doppeladenome der Nebenschilddrüsen gefunden. Das intakte Parathormons (iPTH) im Serum wurde zu Beginn der Operation, nach Präparation der vergrösserten Nebenschilddrüse bei noch erhaltenem Gefässstiel, sowie 5, 10 und 15 Minuten nach der Parathyreoidektomie gemessen. Für den Erfolg der Operation wurde ein Abfall des iPTH um mehr als 50% vom Ausgangswert innerhalb der ersten 5 Minuten, sowie um mehr als 60% innerhalb der ersten 10 Minuten festgelegt. Bei solitären Adenomen der Nebenschilddrüse kam es bereits 5 Minuten nach der Parathyreoidektomie zu einem durchschnittlichen Abfall des iPTH um 61±19% vom Ausgangswert und nach 10 Minuten um 73±17%. Bei einer Hyperplasie der Nebenschilddrüse blieb dieser schnell eintretende steile Abfall des iPHT aus, der Rückgang des iPHT-Spiegels war zögerlich und erreichte erst nach subtotaler Parathyreoidektomie Normalwerte. In dem vorliegenden Patientengut wurden drei falsch-negative sowie ein falsch-positiver Befund beobachtet. Prognostisch ergibt sich für ein solitäres Adenom unserem Patientengut eine Sensitivität von 96% und eine Spezifität von 91% für den 10 Minuten-Wert. Der prädiktive Wert des positiven Tests beträgt 97%. Die vorliegende Arbeit zeigt, dass mit Hilfe der intraoperativen iPTH-Messung die Sicherheit in der Chirurgie des Parathyreoidismus gesteigert werden kann, vor allem beim Vorliegen eines Doppeladenoms oder bei schwierigen Rezidiveingriffen.

description: Coleoptile/mesocotyl elongation influence seedling emergence and establishment, is major causes of maize deep-seeding tolerance (DST). Detailed analyses on molecular basis underlying their elongation mediated by brassinosteroid under deep-seeding stress (DSS) could provide meaningful information for key factors controlling their elongation. Here we monitored transcriptome and phytohormones changes specifically in elongating coleoptile/mesocotyl in response to DSS and 24-epibrassinolide (EBR)-signaling. Phenotypically, contrasting maize evolved variant organs to positively respond to DST, longer coleoptile/mesocoty of K12/W64A was a desirable organ for seedling under DSS. Applied-EBR improved maize DST, and their coleoptiles/mesocotyls were further elongated. 15,607/20,491 differentially expressed genes (DEGs) were identified in W64A/K12 coleoptile, KEGG analysis showed plant hormone signal transduction, starch and sucrose metabolism, valine, leucine, and isoleucine degradation were critical processes of coleoptile elongation under DSS and EBR signaling, further highly interconnected network maps including 79/142 DEGs for phytohormones were generated. Consistent with these DEGs expression, interactions, and transport, IAA, GA3, ABA, and Cis-ZT were significantly reduced while EBR, Trans-ZT, JA, and SA were clearly increased in coleoptile under DSS and EBR-signaling.

description: The present paper addresses the swing equation with additional delayed damping as an example for pendulum-like systems. In this context, it is proved that recurring sub- and supercritical Hopf bifurcations occur if time delay is increased. To this end, a general formula for the first Lyapunov coefficient in second order systems with additional delayed damping and delay-free nonlinearity is given. In so far the paper extends results about stability switching of equilibria in linear time delay systems from Cooke and Grossman. In addition to the analytical results, periodic solutions are numerically dealt with. The numerical results demonstrate how a variety of qualitative behaviors is generated in the simple swing equation by only introducing time delay in a damping term.

description: Askola Peters
 Askola Peters, 1969: 253. (Type-species: Askola froehlichi Peters).
 Discussion: Askola can be distinguished from the other genera of Leptophlebiidae by the following combination of characters, in the imago: 1) hind wings absent; 2) MA fork slightly asymmetrical, MP fork symmetrical; 3) vein ICu1 of fore wings joined at base to vein CuA; 4) claws of a pair dissimilar, one apically hooked and the other blunt; 5) penes divided, tubular, slender, apically pointed, and without appendages or spines (Figs. 28–36); and 6) female with egg guide prolonged to middle of abdominal sternum IX and 7) female sternum IX deeply cleft apically. In the nymph: 1) hind wing pads absent; 2) anteromedian emargination of labrum with two small denticles; 3) denticles of tarsal claws progressively larger apically; 4) dorsal and ventral portions of abdominal gills I–VII equal and plate-like, with the apical half of each plate bordered with finger-like processes; 5) posterolateral spines present on abdominal segments V–IX or VI–IX.
The generic description of the male imago needs to be emended with the following characters to include the variations reported for the new species: 1) eyes separated (Fig 8) or meeting (Figs. 2, 6 and 11) on meson of head; 2) wings hyaline (Fig 27) or spotted (Figs. 1, 25, 26), costal cross veins basad to bullae absent (Fig. 27) or present (Figs. 25–26); 3) penes extending (Figs. 28, 34) or not (Fig 31) beyond posterior margin of styliger plate.

New Model for the QCD Analytic Running Coupling

description: As an elaboration of the analytic approach to Quantum Chromodynamics (QCD), a new model for the QCD analytic running coupling is proposed. A self-evident advantage of the new analytic running coupling (NARC) is that it incorporates the infrared enhancement and the ultraviolet asymptotic freedom in a single expression. It is essential that additional parameters are not introduced in the theory. The absence of unphysical singularities in the physical region $q^2>0$ and a fairly well loop and scheme stability are the remarkable features of the NARC. By making use of practically the same values of $Λ_{QCD}$ in the approach developed, one succeeded in description of various physical phenomena, from quark confinement to the $τ$ lepton decay. This undoubtedly implies that the new analytic running coupling substantially involves both the nonperturbative and the perturbative behavior of Quantum Chromodynamics.

description: With the increasing demand for green energy, the cheap tea waste is recycled to produce three-dimensional framework of porous carbon nanosheets materials with commercial value and excellent electrochemical properties. The TPCN-6 materials were prepared by simultaneous pyrolysis/activation. The density and pore structure of the material depend on the activation concentration. Due to the microporous structure and reasonable pore size distribution of the porous carbon, the TPCN material shows a high specific capacitance of 482.1 F g-1 at 1 A g-1 and perfect cycling stability (retaining 87.6% after 6000 cycles at 10 A g-1) in 6 M KOH aqueous electrolyte. The optimum symmetric supercapacitor device base on TPCN-6//TPCN-6 diaplayed a supreme energy density of 19.1 Wh kg-1 and power density of 325 W kg-1. What's more, it offers a potential way to recycle tea waste into high-valued product in large-scale with disposing of biological waste to relieve environmental concerns.

description: Additive manufacturing strives to combine any combination of materials into three dimensional functional structures and devices, ultimately opening up the possibility of 3D printed machines. It remains difficult to actuate such devices, thus limiting the scope of 3D printed machines to passive devices or necessitating the incorporation of external actuators that are manufactured differently. Here we explore 3D printed hybrid thermoplast/conducter bilayers, that can be actuated by differential heating caused by externally controllable currents flowing through their conducting faces. We uncover the functionality of such actuators and show that they allow to 3D print, in one pass, simple flexible robotic structures that propel forward under step-wise applied voltages. Moreover, exploiting the thermoplasticity of the non-conducting plastic parts at elevated temperatures, we show how strong driving leads to irreversible deformations - a form of 4D printing - which also enlarges the range of linear response of the actuators. Finally, we show how to leverage such thermoplastic relaxations to accumulate plastic deformations and obtain very large deformations by alternatively driving both layers of a bilayer; we call this ratcheting. Our strategy is scalable and widely applicable, and opens up a new approach to reversible actuation and irreversible 4D printing of arbitrary structures and machines.
