String Propagators in Time-Dependent and Time-Independent Homogeneous Plane Waves
Creators: name: Ryang, Shijong
Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: For a special time-dependent homogeneous plane wave background that includes a null singularity we construct the closed string propagators. We carry out the summation over the oscillator modes and extract the worldsheet spacetime structures of string propagators specially near the singularity. We construct the closed string propagators in a time-independent smooth homogeneous plane wave background characterized by the constant dilaton, the constant null NS-NS field strength and the constant magnetic field. By expressing them in terms of the hypergeometric function we reveal the background field dependences and the worldsheet spacetime structures of string propagators. The conformal invariance condition for the constant dilaton plays a role to simplify the expressions of string propagators.

Oblique frozen modes in periodic layered media

description: We study the classical scattering problem of a plane electromagnetic wave incident on the surface of semi-infinite periodic stratified media incorporating anisotropic dielectric layers with special oblique orientation of the anisotropy axes. We demonstrate that an obliquely incident light, upon entering the periodic slab, gets converted into an abnormal grazing mode with huge amplitude and zero normal component of the group velocity. This mode cannot be represented as a superposition of extended and evanescent contributions. Instead, it is related to a general (non-Bloch) Floquet eigenmode with the amplitude diverging linearly with the distance from the slab boundary. Remarkably, the slab reflectivity in such a situation can be very low, which means an almost 100% conversion of the incident light into the axially frozen mode with the electromagnetic energy density exceeding that of the incident wave by several orders of magnitude. The effect can be realized at any desirable frequency, including optical and UV frequency range. The only essential physical requirement is the presence of dielectric layers with proper oblique orientation of the anisotropy axes. Some practical aspects of this phenomenon are considered.

Development Paradigms and Peacebuilding Theories of Change : Analysing Embedded Assumptions in Development and Peacebuilding
Creators: name: JANTZI, TERRENCE L.

Publisher: name: American University
Year: 2023

description: Peacebuilding and development professionals typically draw on different theoretical frameworks for developing their programmes. Development professionals reference the paradigms of development whereas peacebuilding professionals reference theories of change. These two different frameworks make it difficult for these professionals to communicate across their disciplines, even though they are increasingly engaging in very similar forms of intervention. This article develops a framework for correlating the respective development paradigms with peacebuilding theories of change. It concludes by examining the implications for three practitioner-level issues: assimilative versus transformative models, the conundrum of practitioner imperialism, and the normative question of which model is correct.

description: In this review we discuss the relationship between random matrix theories and symmetric spaces. We show that the integration manifolds of random matrix theories, the eigenvalue distribution, and the Dyson and boundary indices characterizing the ensembles are in strict correspondence with symmetric spaces and the intrinsic characteristics of their restricted root lattices. Several important results can be obtained from this identification. In particular the Cartan classification of triplets of symmetric spaces with positive, zero and negative curvature gives rise to a new classification of random matrix ensembles. The review is organized into two main parts. In Part I the theory of symmetric spaces is reviewed with particular emphasis on the ideas relevant for appreciating the correspondence with random matrix theories. In Part II we discuss various applications of symmetric spaces to random matrix theories and in particular the new classification of disordered systems derived from the classification of symmetric spaces. We also review how the mapping from integrable Calogero--Sutherland models to symmetric spaces can be used in the theory of random matrices, with particular consequences for quantum transport problems. We conclude indicating some interesting new directions of research based on these identifications.

Perpetual Peacekeeping? Lessons from Rwanda on Structural Conflict Prevention in the New Aid Environment
Creators: name: LEANDER, SEBASTIAN SILVA
Publisher: name: American University
Year: 2023

description: This paper reviews the history of development assistance to Rwanda since the genocide of 1994 in the light of the lessons learnt from the pre-war experience. The study highlights the continued lack of analysis and understanding among donors of the impact of development assistance on structural causes of conflict. Where analysis exists, it is rarely linked to aid allocation decisions, and where actions are taken in this direction, they are rarely consistent across donors. The paper argues that the United Nations could play a role in bridging the gap between development and conflict prevention by extending some key political monitoring functions currently carried out as part of peacekeeping missions to post-conflict and fragile states that are not currently in crisis.

description: We develop theoretical arguments that demonstrate the possibility of metallic field-effect transistors (METFET's) in one-dimensional systems and particularly in armchair carbon nanotubes. A very inhomogeneous electric field, such as the field of a tunnelling tip, can penetrate the relatively weakly screened nanotubes and open an energy gap. As a consequence, an energy barrier forms that impedes electron flow and thus permits transistor action. This type of metallic field effect is advantageous because of the high conductance of the metallic tubes in the ON--state.

description: A few bacteria can use nitrogen from the atmosphere, but plants cannot. The successful transfer pf the genes responsible for nitrogen fixation from Klebsiella to Escherichia raised the possibility of using gene manipulation to create nitrogen-fixing crops. Ecological factors affect the efficiency of nitrogen fixation and reduce the energy devoted to produce ammonia. Introduction of hup genes into deficient Rhizobium would create superior strains, and the potential for environmental damage is minimum. To reduce the isolation of scientists working in Biological Nitrogen Fixation, the Caribbean Rhizobium Group (CRG) was established in 1984. Similar networks, supported by UNESCO (MIRCEN's) already exist. The initiation of BNFNET, a computer linkage conference, should facilitate the exchange of information and resources in the region.

description: Microfluidic chips provide unparalleled control over droplets and jets, which have advanced all natural sciences. However, microfluidic applications could be vastly expanded by increasing the per-channel throughput and directly exploiting the output of chips for rapid additive manufacturing. We unlock these features with in-air microfluidics, a new chip-free platform to manipulate microscale liquid streams in the air. By controlling the composition and in-air impact of liquid microjets by surface tension-driven encapsulation, we fabricate monodisperse emulsions, particles, and fibers with diameters of 20 to 300um at rates that are 10 to 100 times higher than chip-based droplet microfluidics. Furthermore, in-air microfluidics uniquely enables module-based production of three-dimensional (3D) multiscale (bio)materials in one step because droplets are partially solidified in-flight and can immediately be printed onto a substrate. In-air microfluidics is cytocompatible, as demonstrated by additive manufacturing of 3D modular constructs with tailored micro-environments for multiple cell types. Its in-line control, high throughput and resolution, and cytocompatibility make in-air microfluidics a versatile platform technology for science, industry, and health care.
Two-dimensional incompressible viscous flow around a small obstacle

description: In this work we study the asymptotic behavior of viscous incompressible 2D flow in the exterior of a small material obstacle. We fix the initial vorticity $ω_0$ and the circulation $γ$ of the initial flow around the obstacle. We prove that, if $γ$ is sufficiently small, the limit flow satisfies the full-plane Navier-Stokes system, with initial vorticity $ω_0 + γδ$, where $δ$ is the standard Dirac measure. The result should be contrasted with the corresponding inviscid result obtained by the authors in [Comm P.D.E. 28 (2003) 349-379], where the effect of the small obstacle appears in the coefficients of the PDE and not only on the initial data. The main ingredients of the proof are $L^p-L^q$ estimates for the Stokes operator in an exterior domain, a priori estimates inspired on Kato's fixed point method, energy estimates, renormalization and interpolation.

description: Die Terrassenlandschaft des Lech zwischen Landsberg und Schongau umfaßt wenigstens 16 scharf ausgeprägte würm- und postwürmglaziale Terrassenstufen. Die obersten (ältesten) sechs Stufen sind mit den Endmoränenständen des Lechgletschers zu parallelisieren, die zweitjüngste Stufe ist durch begrabene frührömische Funde relativ exakt datierbar. Die Grenze zwischen Spät- und Postglazial wird mit Hilfe bodenkundlicher Vergleichsuntersuchungen ermittelt. Die ungestörten Maximalbodenbildungen der einzelnen zeitlich fixierten Terrassenstufen werden beschrieben. Erhebliche Entwicklungsunterschiede zwischen den Böden der Niederterrassen und denen der Postglazialterrassen sind nur durch eine bereits im Spätglazial erfolgte, starke Bodenbildung erklärbar. Ein Vergleich von Acker- und Waldprofilen zeigt die starke Veränderung der Böden unter dem Einfluß der landwirtschaftlichen Bodennutzung.

description: Rhizoma perennial peanut (RPP) is a perennial relative of the commercial peanut (A. hypooea) that is planted and perennates by means of rhizomes. Two cultivars,'Florigraze' and 'Arbrook', have been released by the University of Florida for use as a forage for well-drained soils of the tropics and subtropics. In clipping trials, dry matter (DM) production has ranged between 6 to 12 Mg ha-1. Forage quality is similar to alfalfa, with the whole plant crude protein (CP) between 12 to 18% and digestibility between 60 to 75%. Animal performance on RPP pastures (.9 to 1.0 kg d ) has been superior to that from most N-fertilized tropical grasses. Rhizoma perennial peanut persists well under a wide range of management systems for both hay production and grazing (rotational and continuous). Feeding trials and grazing studies indicated that RPP is suitable for dairy rations, backgrounding systems, creep grazing calves, and as limit-fed protein supplement.

description: The observed correlation between the far-infrared and radio luminosities of galaxies illustrates the close connection between star formation and cosmic-ray production. Intriguingly, recent gamma-ray observations indicate that recycled/millisecond pulsars (MSPs), which do not trace recent star formation, may also efficiently accelerate cosmic-ray electrons. We study the contribution of MSPs to the galactic non-thermal radio emission, finding that they can dominate the emission from massive quiescent galaxies. This model can explain recent LOFAR observations that found a peculiar radio excess in galaxies with high stellar masses and low star-formation rates. We show that MSP-based models provide a significantly improved fit to LOFAR data. We discuss the implications for the radio-FIR correlation, the observation of radio excesses in nearby galaxies, and local electron and positron observations.

Lattice gas cellular automata model for rippling and aggregation in myxobacteria

description: A lattice-gas cellular automaton (LGCA) model is used to simulate rippling and aggregation in myxobacteria. An efficient way of representing cells of different cell size, shape and orientation is presented that may be easily extended to model later stages of fruiting body formation. This LGCA model is designed to investigate whether a refractory period, a minimum response time, a maximum oscillation period and non-linear dependence of reversals of cells on C-factor are necessary assumptions for rippling. It is shown that a refractory period of 2-3 minutes, a minimum response time of up to 1 minute and no maximum oscillation period best reproduce rippling in the experiments of {\it Myxoccoccus xanthus}. Non-linear dependence of reversals on C-factor is critical at high cell density. Quantitative simulations demonstrate that the increase in wavelength of ripples when a culture is diluted with non-signaling cells can be explained entirely by the decreased density of C-signaling cells. This result further supports the hypothesis that levels of C-signaling quantitatively depend on and modulate cell density. Analysis of the interpenetrating high density waves shows the presence of a phase shift analogous to the phase shift of interpenetrating solitons. Finally, a model for swarming, aggregation and early fruiting body formation is presented.

description: We study the impact of conflict on both the extensive and the intensive margin of child labor in Afghanistan. We identify and test two main mechanisms. First, if conflict reduces a household income through a decline in parent's compensations, child labor may insure against the decrease in consumption (extensive margin). Second, a child may work longer hours if the marginal benefits of working under conflict is greater than its marginal cost, which may depend on the relative compensations between adults and children, and on the alternative activities (e.g. schooling). Using detailed conflict data from the Afghan War Diary we identify the effect of conflict relying on a shift-share IV strategy. We find that conflict increases the probability that girls work, but reduces the number of hours worked. Our results suggest that this is due to a decrease in household income and an increase in the relative compensations of adults.

description: Es wird immer schwieriger, vergleichende Studien über die zahlreichen Pollendiagramme eines Interglazials innerhalb Nordwesteuropas oder aber verschiedener Interglaziale dieses Raumes zu machen, und zwar wegen der Mannigfaltigkeit der Zonierungssysteme, die die einzelnen Autoren anwenden. Dennoch haben aber Iversen (1958) und Andersen (1966) gezeigt, daß in jedem der bisher untersuchten Interglaziale ähnliche Zyklen der Vegetationsentwicklung und der Bodenbildung abgelaufen sind. Die Verfasser legen dar, daß in jeder Interglazialzeit 4 Perioden der Vegetationsentwicklung festgestellt werden können und daß diese als natürliche biostratigraphische Zonen angesehen werden können, basierend auf dem Charakter der Pollengemeinschaften. Diese Perioden sind: Zone I, die Pre-temperate Zone, Betula und Pinus dominieren; Zone II, die Early-temperate Zone, Vorherrschaft der Bäume des Eichenmischwaldes; Zone III, die Late-temperate Zone, in zunehmendem Maße beherrscht durch spät einwandernde wärmeliebende Bäume, wie Carpinus und Abies; Zone IV, die Post-temperate Zone, wiederum beherrscht durch boreale Bäume, wie Pinus und Betula. Diese Zonierung kann für fast alle interglazialen Pollendiagramme Nordwesteuropas verwandt werden. Geringe Veränderungen der Vegetation, und zwar regional, lokal oder seral, können als Unterzonen beschrieben werden, ohne die Hauptzüge und den Zweck dieses Zonierungssystems zu stören.

The role of surface energy of boron nitride on gross melt fracture elimination of polymers
Creators: name: Seth, Manish
Publisher: name: University of British Columbia
Year: 2011

description: Experiments were carried out to measure the surface energy of boron nitride (BN) powders. A reliable procedure has been developed for measurement of surface energy of powders using the capillary rise technique based on Washburn's equation. It is measured by finding the contact angle from liquid penetration experiments with polar and non-polar liquids. Both the dispersive and non-dispersive components of surface energy are determined. The results of the surface energy of BN powders has been found to correlate well with the critical shear rate for the onset of melt fracture, indicating the importance of surface energy in the procedure of selecting an effective processing aid. In addition, experiments were carried out in both an Instron capillary rheometer equipped with a special annular die (Nokia Maillefer wire coating cross-head) and a parallel-plate rheometer to investigate the effect of a new processing additive (boron nitride powder in combination with a fluoroelastomer) on the rheology and processability of molten polymers. Metallocene polyethylenes with and without boron nitride (BN) and fluoroelastomer are tested in extrusion. First, it is demonstrated that BN is a superior processing aid compared to conventional fluoropolymer ones. Secondly, it is found that the combination of BN powders with a small amount of a fluoroelastomer improves even further the processability of molten polymers. They can essentially be processed at higher shear rates without exhibiting gross melt fracture. DSC and TGA experiments using polymer specimens with and without BN were also carried out to investigate the mechanism by which gross melt fracture is being eliminated in the presence of boron nitride.

This noise comes from a number of sources, from presence of extraneous signals to adjustments in signal amplification and shot noise in the circuits used for data collection. The noise needs to be removed in order to maximize the information gained about the patient using both manual and automatic analysis of the signals. Here we evaluate a number of new techniques for removal of that noise, and the associated problem of separating the original signal sources.

description: We discuss the modified gravity which may produce the current cosmic aceleration of the universe and eliminates the need for dark energy. It is shown that such models where the action quickly grows with the decrease of the curvature define the FRW universe with the minimal curvature. It is required the infinite time to reach the minimal curvature during the universe evolution. It is demonstrated that quantum effects of conformal fields may strongly suppress the instabilities discovered in modified gravity. We also briefly speculate on the modification of gravity combined with the presence of the cosmological constant dark energy.

The Quantum Recursive Granular theory of space, time and light
Creators: name: Rabbani, Hassan Rabbani
Publisher: name: Zenodo
Year: 2024
Subjects: • Quantum Granularity • Infinite dimensions • Light wave Collapse • Recursive time • Quantum Space Dynamics

description: In this work, I introduce a novel conceptual framework where space is envisioned as a granular structure akin to the tissues within the palm of a hand, consisting of discrete elements and infinite dimensions Particles and light, in their wave-like nature, interact with this granular space, where narrow regions render certain quantum states invisible. Light does not propagate through singular dimensions but instead traverses infinite dimensions, existing primarily within the quantum realm. This theory integrates a recursive quantum mechanism where time itself is both a quantum factor and a dimension, iterating in discrete steps. The framework explores the interaction between visible and invisible states of matter and light as they emerge from quantum granularity.

description: This study examines the mechanical behavior of a novel class of mechanical metamaterials alternating pentamode lattices and stiffening plates. The unit cell of such lattices consists of a sub-lattice of the face cubic-centered unit cell typically analyzed in the current literature on pentamode materials. The studied systems exhibit only three soft deformation modes in the infinitesimal stretch-dominated regime, as opposed to the five zero-energy modes of unconfined pentamode lattices. We develop analytical formulae for the vertical and bending stiffness properties and study the dependence of such quantities on the main design parameters: the lattice constant, the solid volume fraction, the cross-section area of the rods, and the layer thickness. A noteworthy result is that the effective compression modulus of the analyzed structures is equal to two thirds of the Young modulus of the stiffest isotropic elastic networks currently available in the literature, being accompanied by zero-rigidity against infinitesimal shear and twisting mechanisms. The use of the proposed metamaterials as novel seismic-isolation devices and impact-protection equipment is discussed by drawing comparisons with the response of alternative devices already available or under development.

description: Anti-Stokes photoluminescence of metal nanoparticles, in which emitted photons have a higher energy than the incident photons, is an indicator of the temperature prevalent within a nanoparticle. Previous work has shown how to extract the temperature from a gold nanoparticle under continuous-wave monochromatic illumination. We extend the technique to pulsed illumination and introduce pump-probe anti-Stokes spectroscopy. This new technique enables us not only to measure an effective electron temperature in a gold nanoparticle ($\sim 10^3$ K under our conditions), but also to measure ultrafast dynamics of a pulse-excited electron population, through its effect on the photoluminescence, with sub-picosecond time resolution. We measure the heating and cooling, all within picoseconds, of the electrons and find that, with our sub-picosecond pulses, the highest apparent temperature is reached $0.6$ ps before the maximum change in magnitude of the extinction signal

description: This paper explores the use of genetic algorithms for the design of networks, where the demands on the network fluctuate in time. For varying network constraints, we find the best network using the standard genetic algorithm operators such as inversion, mutation and crossover. We also examine how the choice of genetic algorithm operators affects the quality of the best network found. Such networks typically contain redundancy in servers, where several servers perform the same task and pleiotropy, where servers perform multiple tasks. We explore this trade-off between pleiotropy versus redundancy on the cost versus reliability as a measure of the quality of the network.

description: We propose a way to make arrays of optical frequency dipole-force microtraps for cold atoms above a dielectric substrate. Traps are nodes in the evanescent wave fields above an optical waveguide resulting from interference of different waveguide modes. The traps have features sought in developing neutral atom based architectures for quantum computing: ~ 1 mW of laser power yields very tight traps 150 nm above a waveguide with trap vibrational frequencies ~ 1 MHz and vibrational ground state sizes ~ 10 nm. The arrays are scalable and allow addressing of individual sites for quantum logic operations.

description: This document contains the first official version of the XChronos Synchronicity Diary, authored by Jaconaazar Souza Silva. It records a series of phenomenological and symbolic experiences related to altered perception of time, language, digital interfaces, and reality itself. Each entry is marked by a symbolic timestamp called a Crônon, and in some cases by Hexachronons and Metachronons—representing expanded or layered states of time consciousness. The diary combines subjective narrative with astrophysical data, digital phenomena, and semantic anomalies, offering a proposal for symbolic temporal mapping rooted in lived experience.

description: We present results of numerical simulations which examine the dynamical stability of known planetary systems, a star with two or more planets. First we vary the initial conditions of each system based on observational data. We then determine regions of phase space which produce stable planetary configurations. For each system we perform 1000 ~1 million year integrations. We examine upsilon And, HD83443, GJ876, HD82943, 47UMa, HD168443, and the solar system (SS). We find that the resonant systems, 2 planets in a first order mean motion resonance, (HD82943 and GJ876) have very narrow zones of stability. The interacting systems, not in first order resonance, but able to perturb each other (upsilon And, 47UMa, and SS) have broad regions of stability. The separated systems, 2 planets beyond 10:1 resonance, (we only examine HD83443 and HD168443) are fully stable. Furthermore we find that the best fits to the interacting and resonant systems place them very close to unstable regions. The boundary in phase space between stability and instability depends strongly on the eccentricities, and (if applicable) the proximity of the system to perfect resonance. In addition to million year integrations, we also examined stability on ~100 million year timescales. For each system we ran ~10 long term simulations, and find that the Keplerian fits to these systems all contain configurations which may be regular on this timescale.

description: A survey of archaeological specialists has found that, in early 2017, specialists appear to have recovered from the economic downturn of the previous decade, but are cautious about the possibility that there will be increased demand for their services in the near to medium future. This study, which has aimed to collect data from a wide variety of areas of specialist activity within archaeology, received information from 882 specialists. The synthetic results presented here allow for comparison between specialisms and across broad specialist areas. A parallel survey, for buildings history and garden history, is presented in a separate report. Comments received from respondents make it clear that not everyone who is working in this sector is doing this to earn a living, as some are delivering services on a voluntary basis.

description: Medical case notes (MCNs), like other forms of medical discourse provide information on a patient’s health condition and its treatment. However, previous studies on medical discourse have focused more on doctor – patient interaction than on doctor’s written communication, predominant of which is the medical case notes (MCNs). This study therefore, examined the exploration of co-operation in selected MCNs with a view to establishing the observance and non-observance of the conversational maxims; and the implicit meanings in MCNs. The study adopted the Gricean theoretical notion of implicature as its theoretical framework. Twenty medical case notes were purposively sampled from five privately owned hospitals in Ibadan and subjected to pragmatic analysis. The study revealed that the way language is employed by medical practitioners does not reflect an indiscriminate deployment of linguistic resources, but deliberate discursive practices that have definable shapes and implications for the profession. Our findings also showed that conversational maxims were both flouted and obeyed in the selected medical case notes. The study further observed that the recovery of implicatures was based on the non-observance of some maxims. A study of implicatures in medical case notes should assist in understanding medical discourse, and aid access to the intended meaning of the writer vis-à-vis the overall interpretation of the text. For adequate understanding of these texts by other medical personnel or any other authorized body, the study recommended the utilisation of contextual features in the interpretation of MCNs. Key words: Medical case notes, co-operative principle, implicatures, information and health

WHEN DEVELOPMENT MEETS CULTURE AND CONFLICT : THE CHALLENGES AND PARADOXES OF THE GOOD SAMARITAN

Subjects: classificationCode: 44
subject: Human society

description: This essay examines the nexus between development, culture and conflict. It finds that development is not so much a well-intentioned process to raise the well-being of poor people. Rather, it is the product of a political agenda that has transformed itself over time yet continues to be characterised by insufficient attention to the goals, cultural values and agency of those for whom development support is intended. The result is that development, even when well intentioned, can contribute to increased conflict. This paper finds that some of the approaches used in effective conflict resolution could usefully be incorporated into development theory and practice.
