    Missing Persons: Cherokee\u27s Parrot and Chatterton\u27s Poet

    Get PDF
    This essay explores the problematic nature of selfhood in the detective genre as established by Edgar Allan Poe\u27s Murders in the Rue Morgue (1841) and most recently reformulated in two metaphysical detective novels, Jean Echenoz\u27s Cherokee (1983) and Peter Ackroyd\u27s Chatterton (1987). Poe\u27s detective Auguste Dupin is described as having a Bi-Part Soul, which permits him to vacate himself in order to construct the narrative solution to a crime. This duality, in the postmodern detective novel, is transformed into an irrevocable dislocation of the subject. Cherokee\u27s onomastic devalorization of the story\u27s characters and simulation of the human subject in the figure of the parrot Morgan create an indeterminacy that renders traditional conceptions of the self obsolete or irrelevant. Chatterton, whose point of departure is the infamous eighteenth-century forger Thomas Chatterton, uses the issue and example of pastiche to problematize the notion of the constitution of a subject in language and time. Both Cherokee and Chatterton take advantage of the subjective presuppositions of the detective genre in order to delineate the intricate problems of selfhood as a postmodern concern

    Novel Methods for Modern NMR Spectroscopy - Optimized Pulses and New Experiments

    Get PDF
    Die NMR-Spektroskopie verdankt ihre Flexibilität der Vielzahl möglicher NMR-Experimente. Im Rahmen dieser Arbeit wurden NMR Pulse, die Bausteine der Experimente, mit Methoden der Optimal Control Theory optimiert und mehrere neue Experimente entwickelt: Das CLIP-COSY, ein homonukleares Korrelationsexperiment, wird vorgestellt. Verbesserungen und theoretische Betrachtungen zum ASAP-HSQC, einem heteronuklearen Korrelationsexperiment, werden beschrieben. Abschließend werden Experimente zur Analyse inhomogener und anisotroper Proben, die die Messung von RDCs vereinfachen, präsentiert

    Patent Protection for a Method of Ratoon Rice Management in Supporting Food Security

    Pursuant to Article 25 Universal Declaration of Human Rights (1945) that: “Everyone has the right to a standard of living, adequate health and well-being of himself and his family including the right for food”. Essentially food security can be described as” a phenomenon relating to individual food security which exists when all people at all the times have physical , social and economic access to sufficient, safe and nutritious food which meet their dietary needs and food preferences for an active and healthy life”. However, since 2009 the food security situation has worsened and continuous to pose a serious threat especially in the developing nations. The internationally agreed target from the World Food Summit of 1996 to halve hunger by 2015 was not met. Despite progress in some countries, United Nations Food and Agricultural Organization (FAO)’s estimates in 1997-1999 there 865 million people were undernourished, 777 million in developing countries, 27 million in transition countries and 11 million in the industrialized countries. Even if the target is met, it would still leave 400 million people under nourished. The fact that in the year 2017 there was 19, 4 million Indonesian people who did not meet their required food needs.Pursuant to Article 33 paragraph 3 of the 1945 Constitution (UUD1945) stated that: “The earth, the water and all the wealth contained therein are controlled by the State and used as much as possible for the welfare of the people. Production branches that are important and affect the livelihood of many people controlled by the State shall be used for the greatest prosperity of the people.” This paper will argue that the Method of Ratoon’s Rice Management will benefit in supporting Food Security because it has many advantages over the conventional rice cultivation. The Patent right as legalized monopoly is sought to prevent the abuse of this invention by irresponsible parties

    DAC-Less amplifier-less generation and transmission of QAM signals using sub-volt silicon-organic hybrid modulators

    Get PDF
    We demonstrate generation and transmission of optical signals by directly interfacing highly efficient silicon-organic hybrid (SOH) modulators to binary output ports of a field-programmable gate array. Using an SOH Mach-Zehnder modulator (MZM) and an SOH IQ modulator we generate ON-OFF- keying and binary phase-shift keying signals as well as quadrature phase-shift keying and 16-state quadrature amplitude modulation (16QAM) formats. Peak-to-peak voltages amount to only 0.27 V-pp for driving the MZM and 0.41 V-pp for the IQ modulator. Neither digital-to-analog converters nor drive amplifiers are required, and the RF energy consumption in the modulator amounts to record-low 18 fJ/bit for 16QAM signaling

    Ultra-short silicon-organic hybrid (SOH) modulator for bidirectional polarization-independent operation

    Get PDF
    We propose a bidirectional, polarization-independent, recirculating IQ-modulator scheme based on the silicon-organic hybrid (SOH) platform. We demonstrate the viability of the concept by using an SOH Mach-Zehnder modulator, operated at 10 GBd BPSK and 2ASK-2PSK

    40 Gbit/s silicon-organic hybrid (SOH) phase modulator

    Get PDF
    A 40 Gbit/s electro-optic modulator is demonstrated. The modulator is based on a slotted silicon waveguide filled with an organic material. The silicon organic hybrid (SOH) approach allows combining highly nonlinear electro-optic organic materials with CMOS-compatible silicon photonics technology
