description: A greenhouse experiment was conducted to determine the effects of transplant timing and terminal bud removal on the growth and development of sorrel (Hibiscus sabdariffa). Sorrel seedlings were transplanted 30, 45 and 60 days after germination and terminal buds removed 15 and 3 0 days after transplanting. Removal of terminal buds reduced plant height as well as the number of branches per plant. However, removing terminal buds 15 days after transplanting had a more severe effect on branching of sorrel plants than terminal bud removal 30 days after transplanting. Time of transplanting or terminal bud removal did not affect chlorophyll or xanthophyll content of sorrel. Stem diameter was significantly affected by both time of transplanting and terminal bud removal. Stem diameter ranged from 1.6 cm for plants transplanted 60 days after germination to 2.4 cm for sorrel transplanted 30 days after germination. Sorrel yield also followed a similar pattern. Dry weight of sorrel calyx was 4.6 grams per plant for 60-day transplants with terminal buds removed 30 days after transplanting to a high of 49.7 grams per plant for 30-day transplants with terminal buds removed 15 days after transplanting.

description: We present the first unrestricted, three-dimensional relativistic hydrodynamical calculations of the blob of gas associated with the jet producing a gamma-ray burst. We investigate the deceleration phase of the blob corresponding to the time when afterglow radiation is produced, concentrating on the transition in which the relativistic beaming 1/gamma goes from being less than theta, where gamma is the bulk Lorentz factor and theta is the angular width of the jet, to 1/gamma > theta. We study the time dependent evolution of the physical parameters associated with the jet, both parallel to the direction of motion and perpendicular to it. We calculate light curves for observers at varying angles with respect to the velocity vector of the blob, assuming optically thin emission that scales with the local pressure. Our main findings are that (i) gas ahead of the advancing blob does not accrete onto and merge with the blob material but rather flows around the blob, (ii) the decay light curve steepens at a time corresponding roughly to 1/gamma equals theta (in accord with earlier studies), and (iii) the rate of decrease of the forward component of momentum in the blob is well-fit by a simple model in which the gas in front of the blob exerts a drag force on the blob, and the cross sectional area of the blob increases quadratically with laboratory time (or distance).

description: Cellular automata are interacting classical bits that display diverse emergent behaviors, from fractals to random-number generators to Turing-complete computation. We discover that quantum cellular automata (QCA) can exhibit complexity in the sense of the complexity science that describes biology, sociology, and economics. QCA exhibit complexity when evolving under "Goldilocks rules" that we define by balancing activity and stasis. Our Goldilocks rules generate robust dynamical features (entangled breathers), network structure and dynamics consistent with complexity, and persistent entropy fluctuations. Present-day experimental platforms -- Rydberg arrays, trapped ions, and superconducting qubits -- can implement our Goldilocks protocols, making testable the link between complexity science and quantum computation exposed by our QCA.

Quantum wave packet revivals in circular billiards

description: We examine the long-term time-dependence of Gaussian wave packets in a circular infinite well (billiard) system and find that there are approximate revivals. For the special case of purely $m=0$ states (central wave packets with no momentum) the revival time is $T_{rev}^{(m=0)} = 8μR^2/\hbar π$, where $μ$ is the mass of the particle, and the revivals are almost exact. For all other wave packets, we find that $T_{rev}^{(m \neq 0)} = (π^2/2) T_{rev}^{(m=0)} \approx 5T_{rev}^{(m=0)}$ and the nature of the revivals becomes increasingly approximate as the average angular momentum or number of $m \neq 0$ states is/are increased. The dependence of the revival structure on the initial position, energy, and angular momentum of the wave packet and the connection to the energy spectrum is discussed in detail. The results are also compared to two other highly symmetrical 2D infinite well geometries with exact revivals, namely the square and equilateral triangle billiards. We also show explicitly how the classical periodicity for closed orbits in a circular billiard arises from the energy eigenvalue spectrum, using a WKB analysis.

Improvements of demosaicking and compression for single sensor digital cameras
Creators: name: Doutre, Colin Ray
Publisher: name: University of British Columbia
Year: 2011

description: Most consumer digital cameras captured colour images using a single light sensor and a colour filter array (CFA). This results in a mosaic image being captured, where at each pixel location either a red, green, or blue sample is obtained. The two missing colours at each location must be interpolated from the surrounding samples in a process known as demosaicking. In most current digital cameras, demosaicking is carried out in RGB colour space and later the image or video is converted to YCbCr 4:2:0 format and compressed with standard methods. Most previous research on demosaicking and compression in digital cameras has addressed the issues separately. That is, current demosaicking methods ignore the fact that the data will later be compressed, and compression techniques ignore the fact that the data was captured with a CFA. In this thesis we proposed two methods for optimizing the demosaicking and compression processes in digital cameras. First we propose a fast demosaicking method that directly produces an image in YCbCr 4:2:0 format (the colour format most commonly used in compression). This reduces the computational complexity relative to the conventional approach of performing demosaicking in the RGB space and later converting to YCbCr 4:2:0 format. Second, we propose two methods for compressing video captured with a CFA prior to demosaicking being performed. This allows us to take advantage of the smaller input data size, since demosaicking expands the number of samples by a factor of three. Our first CFA video compression method uses standard H.264, while our second method uses a modified motion compensation scheme that further increases compression efficiency by exploiting the properties of CFA data.

description: The prevalence of sedentary lifestyles has led to progressively more unhealthy individuals, which contributes to an unproductive workforce. To address these issues and the related expenditures due to healthcare and lost productivity, workplace health promotion programs have acknowledged the capacity of various physical activity interventions including pedometer-based walking programs. Employing an implementation intention approach to these programs and delivering these planning messages through email has potential to strengthen health promotion programs. The purpose of this study is to determine the impact that email-delivered implementation intentions have on physical activity behaviors of participants in a worksite pedometer program. Fifty-six employees at American University who participated in a six-week pedometer challenge were part of a randomized controlled experiment in which intervention group participants received planning emails that featured implementation intentions over the course of the challenge as well as six-weeks post challenge. The results of the study demonstrated a significantly greater increase in walking among intervention group participants during the pedometer program. It was concluded that the use of implementation intention emails may increase adherence to walking in association with a worksite pedometer challenge and that health promotion practitioners should include this approach when designing programs to increase physical activity.

description: An experiment with four levels of N-P-K-Mg fertilization was conducted to determine absorption curves of the macronutrients in Cucumis melo cv. *Honey Dew Green Flesh'. Tissue samples were taken beginning one month after planting and then at fifteen day intervals. Significant variations in nutrient concentrations were found during the crop vegetative growth. These variations were not affected by the levels of fertilization. Higher concentrations of N were observed at 30 and 45 days; K, 60 days; and P, Ca and Mg, 45 days after planting. After the maximum nutrient concentration was reached, the levels started a continuous decrease until the end of the vegetative phase. This pattern was observed for all the nutrients except for the Mg concentration in fruits, in which higher concentrations were observed at the end of the growth phase. Higher nutrient extraction was observed at 45 and 60 days after planting with average values of 47% for N, 62% for P, 57% for K, 51% for Ca and 33% for Mg.

description: Attention is focused on q-deformed quantum algebras with physical importance, i.e. $U_{q}(su_{2})$, $U_{q}(so_{4})$ and q-deformed Lorentz algebra. The main concern of this article is to assemble important ideas about these symmetry algebras in a consistent framework which shall serve as starting point for representation theoretic investigations in physics, especially quantum field theory. In each case considerations start from a realization of symmetry generators within the differential algebra. Formulae for coproducts and antipodes on symmetry generators are listed. The action of symmetry generators in terms of their Hopf structure is taken as q-analog of classical commutators and written out explicitly. Spinor and vector representations of symmetry generators are calculated. A review of the commutation relations between symmetry generators and components of a spinor or vector operator is given. Relations for the corresponding quantum Lie algebras are computed. Their Casimir operators are written down in a form similar to the undeformed case.

Publisher: name: American University
Year: 2023

description: Tidewatchers is an original work of fiction that explores those bonds of blood capable of enduring death. Set on an island in the tidewater region of Virginia, the novel follows the Loops, a family isolated first by their reputation and then by the death of Wavy Loop, the novel's twelve-year old narrator. What begins as a chronicle of Wavy's coming of age in a place on the verge of change becomes an examination of grief as the Loops mourn the life Wavy will never live and Wavy observes the lives she fears she has ruined with her death. Incorporating elements of the fantastic, Tidewatchers tells a story about adolescence, sisterhood, and loss; in doing so, it seeks to reveal the miraculous in what too often appears mundane: family.

Year: 2004

description: A realistic microscopic calculation of the unpolarized quark Generalized Parton Distribution (GPD) $H_q^3$ of the $^3He$ nucleus is presented. In Impulse Approximation, $H_q^3$ is obtained as a convolution between the GPD of the internal nucleon and the non-diagonal spectral function, describing properly Fermi motion and binding effects. The proposed scheme is valid at low values of $Δ^2$, the momentum transfer to the target, the most relevant kinematical region for the coherent channel of hard exclusive processes. The obtained formula has the correct forward limit, corresponding to the standard deep inelastic nuclear parton distributions, and first moment, giving the charge form factor of $^3He$. Nuclear effects, evaluated by a modern realistic potential, are found to be larger than in the forward case. In particular, they increase with increasing the momentum transfer when the asymmetry of the process is kept fixed, and they increase with the asymmetry at fixed momentum transfer. Another relevant feature of the obtained results is that the nuclear GPD cannot be factorized into a $Δ^2$-dependent and a $Δ^2$-independent term, as suggested in prescriptions proposed for finite nuclei. The size of nuclear effects reaches 8 % even in the most important part of the kinematical range under scrutiny. The relevance of the obtained results to study the feasibility of experiments is addressed.

description: We review the contributions of surface science methods to discover and improve 3D topological insulator materials, while illustrating with examples from our own work. In particular, we demonstrate that spin-polarized angular-resolved photoelectron spectroscopy is instrumental to evidence the spin-helical surface Dirac cone, to tune its Dirac point energy towards the Fermi level, and to discover novel types of topological insulators such as dual ones or switchable ones in phase change materials. Moreover, we introduce procedures to spatially map potential fluctuations by scanning tunneling spectroscopy and to identify topological edge states in weak topological insulators.

Report on the conference: Facilities, operation and maintenance of field railways in tourist and museum institutions

description: Abstract: From 30th June 2011 to 1st July 2011 a section 7 conference (regional studies and environmental education) regarding the facilities, operation and maintenance of field railways in tourist and museum institutions was organised by the „German Society for Moor and Peat“ (DGMT) in the „Alten Torfwerk“ in Diepenau-Essern. Particularly in northern Germany, but also at the Chiemsee, institutions meanwhile exist which not only collect and care for the field railways (whether locomotives or wagons) as well as possible, but also use these to transport interested guests. In many areas, however, there is a clear lack of cohesive collection and utilisation concepts. Furthermore questions regarding technical operation are not always conclusively regulated and insufficient thought has been given to statutory requirements. These problems become more acute as the number of field railway routes run by local associations increase as a result of the decline in Germany’s peat industry. The conference, which was held with the kind support of the „Moorbahn Uchter Moor“ association, was to take up issues regarding the planning and operation of field railways for purposes of tourism, as well as discussing the legal problems in connection with these matters. A fundamental purpose of the conference was to sensitise people for a differentiated approach towards the facilities and operation of field railways.

Vor allem im norddeutschen Raum, aber auch am Chiemsee, gibt es inzwischen Einrichtungen, die nicht nur Feldbahnen (ob Loks oder Waggons) sammeln und möglichst pflegen, sondern diese auch dazu nutzen, interessierte Gäste damit zu befördern. Dabei fehlen vielerorts schlüssige Sammlungs- und Nutzungskonzepte. Auch Fragen zum technischen Betrieb sind nicht immer ausreichend geklärt, rechtliche Anforderungen nicht umfassend berücksichtigt. Diese Probleme werden aktueller, da mit dem Rückgang der Torfindustrie in Deutschland durch örtliche Vereine betriebene Feldbahntrassen noch zunehmen. Die mit freundlicher Unterstützung des Vereins Moorbahn Uchter Moor stattgefundene Tagung sollte die mit der Planung und dem touristischen Betrieb von Feldbahnen zusammenhängenden Fragestellungen aufgreifen und rechtliche Problembereiche thematisieren. Grundsätzlich sollte die Tagung für einen differenzierteren Umgang mit der Anlage und dem Betrieb von Feldbahnen sensibilisieren.

description: Although sexual dimorphism in morphological traits (SD) has been widely studied in many animal groups (including arthropods), its developmental mechanisms are poorly understood. As ontogenetic allometry describes whether size of a morphological trait significantly affects changes of its shape during ontogeny, comparison of allometric growth trends between sexes can reveal whether and how intersexual differences in developmental pathways influence the presence and patterns of SD in adults. We studied allometric relationships between 10 morphological traits (head length and width, gnathochilarium length and width, antennal length, trunk length, width and height, leg length, body mass) and body length in different ontogenetic stadia of both sexes of the Balkan endemic millipede Apfelbeckia insculpta (L. Koch, 1867) using bivariate and multivariate analyses. Our sample consisted of 61 males and 60 females belonging to two sub-adult groups (postembryonic stadia VIII and IX) and adults (postembryonic stadium X). All individuals were collected from Hadži Prodanova Pećina Cave (Serbia). We detected that all morphological traits share common slope between sub-adults and adults of the same sex. Significant SD in common slope was detected for head and gnathochilarium dimensions and body mass. Also, these traits, together with antennal and leg length, showed different allometric growth trends between sexes. Our data show that SD in morphological traits in adults is achieved through intersexual differences in growth rates, as well as through differences in allometric growth trends. This study suggests allometric scaling as key process in development of adult body plan in A. insculpta.

description: We consider a quantum mechanical system to model the effect of quantum fields on the evolution of the early universe. The system consists of an inverted oscillator bilinearly coupled to a set of harmonic oscillators. We point out that the role of noise may be crucial in the dynamics of the oscillator, which is analyzed using the theory of harmonic oscillators with random frequency. Using this analogy we argue that, due to the fluctuations around its mean value, a positive vacuum energy density would not produce an exponentially expanding but an oscillating universe, in the same fashion that an inverted pendulum is stabilized by random oscillations of the suspension point (stochastic Kapitza pendulum). The results emphasize the relevance of noise in the evolution of the scale factor.

Durch die Transgression der Moore wurden Kiefern an der Basis der Torfe eingebettet und befinden sich oft am Übergang von Niedermoor- zu Hochmoortorfen. Stubbenhorizonte innerhalb der Torfkörper dokumentieren Bewaldungsphasen der Moore. Durch dendrochronologische Untersuchungen wurden subfossile Kiefern von 40 Fundorten datiert und erstmalig eine Kiefernchronologie für Nordwestdeutschland aufgebaut. Die untersuchten Kiefernhölzer belegen zu bestimmten Zeitabschnitten gehäufte Absterbe- oder Keimungsphasen sowie signifikante Änderungen der Jahrringbreiten der Hölzer aus verschiedenen Mooren. Teilweise zeichnen sich auch bei den früher bearbeiteten subfossilen Eichen zeitparallel entsprechende Phasen ab, so dass diese Signale, klimatisch verursacht, als Abbild von Vernässungsphasen angesehen werden.

description: We give three methods for entangling quantum states in quantum dots. We do this by showing how to tailor the resonant energy (Foerster-Dexter) transfer mechanisms and the biexciton binding energy in a quantum dot molecule. We calculate the magnitude of these two electrostatic interactions as a function of dot size, interdot separation, material composition, confinement potential and applied electric field by using an envelope function approximation in a two-cuboid dot molecule. In the first implementation, we show that it is desirable to suppress the Foerster coupling and to create entanglement by using the biexciton energy alone. We show how to perform universal quantum logic in a second implementation which uses the biexciton energy together with appropriately tuned laser pulses: by selecting appropriate materials parameters high fidelity logic can be achieved. The third implementation proposes generating quantum entanglement by switching the Foerster interaction itself. We show that the energy transfer can be fast enough in certain dot structures that switching can occur on a timescale which is much less than the typical decoherence times.

Do Spirits Have a Place at the Negotiating Table?
Creators: name: Wolgamuth, Erin
Publisher: name: American University

description: In recent decades the field of conflict resolution has increasingly acknowledged culture, worldview, and localized peace-building mechanisms, as integral components of conflict analysis and practice techniques. Nonmaterial beings, like spirits, comprise a significant component of many global worldviews but have not yet been analyzed as a phenomenon by the conflict resolution field. The research question explored in this paper is whether spirits could contribute to conflict resolution as actors in their own right. Content analysis is used to explore cases from Zimbabwe, Madagascar, Mozambique, the United States, and Sri Lanka. I will demonstrate ultimately that spirits should be regarded as actors, much as humans are, in conflict contexts where they have relevant influence.

title: Designing high performance teams for projects : a study of 49 project teams in the UK construction industry
Creators: name: Jenner, Mark Steven
Publisher: name: The Open University
Year: 1997

description: Teams have been presented as a panacea to complex and turbulent business environments, but there are few examples of genuinely high-performing teams. This study considers the utility of work design as a means of improving the performance of project teams and thereby resolving this paradox. Grounded in quantitative methodology, and supported by relevant qualitative data, this study has used a single case experiment to examine the effects of multiple work design variables on the climate and performance of 49 construction project management teams. The single case environment provided an opportunity to study a large number of real work groups, executing broadly similar tasks, while controlling for the effects of organisational culture on social and work behaviour. The results indicated that three levels of intervention - transformational leadership, team organisation and team performance orientation - were influential in either (a) directly influencing project team performance or (b) creating a team climate which was itself predictive of desired outcomes, specifically the moderation of project complexity and higher levels of productivity. In particular, the results showed that the `inspiring a shared vision' leader practice was influential in explaining the perceived satisfaction of customers with project team performance. This provides empirical evidence that visionary leadership is an important determinant of high performance in complex, fluid and uncertain work environments, such as construction project management. Although task orientation and shared vision emerged as reasonably strong performance norms in the sample, it is generally difficult isolating the referent group norm(s) which explain(s) the variation in the performance of project teams working in myriad social, temporal and task conditions. Rather than attempting to manage group behaviour in realtime, therefore, the results of this study suggest that a coherent and integrated package of work design interventions can leverage exceptional value from project teams by helping each team to develop unique performance and behavioural strategies.

description: In this paper, we experimentally evaluate the zero-shot performance of GPT-4 against prior generations of GPT on the entire uniform bar examination (UBE), including not only the multiple-choice multistate bar examination (MBE), but also the open-ended multistate essay exam (MEE) and multistate performance test (MPT) components. On the MBE, GPT-4 significantly outperforms both human test-takers and prior models, demonstrating a 26% increase over ChatGPT and beating humans in five of seven subject areas. On the MEE and MPT, which have not previously been evaluated by scholars, GPT-4 scores an average of 4.2/6.0 when compared with much lower scores for ChatGPT. Graded across the UBE components, in the manner in which a human test-taker would be, GPT-4 scores approximately 297 points, significantly in excess of the passing threshold for all UBE jurisdictions. These findings document not just the rapid and remarkable advance of large language model performance generally, but also the potential for such models to support the delivery of legal services in society.This article is part of the theme issue ‘A complexity science approach to law and governance’.
Tumbling with a Limp: Local Asymmetry in Water's Hydrogen Bond Network and its Consequences

description: Ab initio molecular dynamics simulations of liquid water under equilibrium ambient conditions, together with a novel energy decomposition analysis, have recently shown that a substantial fraction of water molecules exhibit a significant asymmetry between the strengths of the two donor and/or the two acceptor interactions. We refer to this recently unraveled aspect as the "local asymmetry in the hydrogen bond network". We discuss how this novel aspect was first revealed, and provide metrics that can be consistently employed on simulated water trajectories to quantify this local heterogeneity in the hydrogen bond network and its dynamics. We then discuss the static aspects of the asymmetry, pertaining to the frozen geometry of liquid water at any given instant of time and the distribution of hydrogen bond strengths therein, and also its dynamic characteristics pertaining to how fast this asymmetry decays and the kinds of molecular motions responsible for this decay. Following this we discuss the spectroscopic manifestations of this asymmetry, from ultrafast X-ray absorption spectra to infrared spectroscopy and down to the much slower terahertz regime. Finally, we discuss the implications of these findings in a broad context and its relation to the current notions about the structure and dynamics of liquid water.
On the Weyl anomaly of Wilson surfaces

description: We compute the Weyl anomaly for an abelian Wilson surface by using a regularization that respects the gauge invariance. We then study the loop space on which lives a one-form connection. We restrict ourselves to the subsector consisting of only circular loops, and derive a Maxwell type action on this restricted loop space.

Child labour and economic growth in Kenya

Publisher: name: figshare

Subjects: Economics

description: In 2017, the International Labour Organization reiterated that elimination of worst forms
of child labour has been recognized to be critical pertaining to social and economic
development sustainability. Child labour will continue to persist from now on and several
decades to come in the Kenyan economy if not curbed. Kenya’s Gross Domestic Product
increased rapidly from 18.7 billion US $ in 2005, to 63.8 billion US $ in 2015. Child
labour rose steadily from 2.4 million child labourers in 2005 to 3.7 million child
labourers in 2015, despite positive increment in Kenya’s Gross Domestic Product in
Kenya from 2005 to 2015. From trends discussed in chapter one, it appears that positive
increases in economic growth levels alone cannot be the only means to help in reducing
or eliminating child labour in Kenya. Kenya’s Gross Development Product has been
increasing since 1980 to 2017 amidst fluctuations. Despite positive growth in Kenya’s
Gross Domestic Product, there is still an increase in child labour. This study sought to
determine the relationship between economic growth and child labour in Kenya. This was
first undertaken by determining the causality between economic growth and child labour
in Kenya. The Toda-Yamamoto modified Granger causality (non-causality) model was
fitted with time series data for the period 1980 to 2017. The estimated results revealed
that there was no causality running from child labour to GDP in Kenya. Furthermore,
there was causality running from GDP to child labour in Kenya. To establish the
existence of a long run relationship between economic growth and child labour in Kenya,
the unrestricted conditional error correction model was used in which economic growth
was the dependent variable. The explanatory variables were child labour, investment in
human capital, international trade openness, population growth and foreign direct
investment. The estimation results revealed that a long run relationship existed between
economic growth and child labour in Kenya. To determine the short run effects of child
labour to economic growth in Kenya, the restricted error correction model was used in
which economic growth was the dependent variable. The estimation results revealed that
the coefficient of child labour was statistically significant in affecting economic growth
of Kenya in the short run. From the empirical results, it was concluded that there was no
causality running from child labour to GDP in Kenya where GDP was the dependent
variable, and also there was causality running from GDP to child labour in Kenya where
child labour was the dependent variable. From the empirical results, it was inferred that a
long run relationship existed between economic growth and child labour in Kenya.
Lastly, the empirical results revealed that there were short run effects of child labour on
economic growth in Kenya.

description: ADM was at the center of two large global price-fixing conspiracies. Buyers were overcharged $116 to $378 million in the United States. Market structure and corporate management style facilitated these cartels. The criminal prosecutions and defendants' legal strategies were both laudatory, but civil plaintiffs were shortchanged. ADM has undergone severe management restructuring, but the effectiveness of apprehending global cartels with national legal enforcement is questionable.
Rational Lagrangian fibrations on punctual Hilbert schemes of K3 surfaces

description: A rational Lagrangian fibration f on an irreducible symplecitc variety V is a rational map which is birationally equivalent to a regular surjective morphism with Lagrangian fibers. By analogy with K3 surfaces, it is natural to expect that a rational Lagrangian fibration exists if and only if V has a divisor D with Bogomolov--Beauville square 0. This conjecture is proved in the case when V is the punctual Hilbert scheme of a generic algebraic K3 surface S. The construction of f uses a twisted Fourier--Mukai transform which induces a birational isomorphism of V with a certain moduli space of twisted sheaves on another K3 surface M, obtained from S as its Fourier--Mukai partner.

description: The space of Lie algebra cohomology is usually described by the dimensions of components of certain degree even for the adjoint module as coefficients when the spaces of cochains and cohomology can be endowed with a Lie superalgebra structure. Such a description is rather imprecise: these dimensions may coincide for cohomology spaces of distinct algebras. We explicitely describe the Lie superalgebras on the space of cohomology of the maximal nilpotent subalgebra of any simple finite dimensional Lie algebra. We briefly review related results by Grozman, Penkov and Serganova, Poletaeva, and Tolpygo. We cite a powerful Premet's theorem complementary to the Borel-Weil-Bott theorem. We mention relations with the Nijenhuis bracket and nonholonomic systems.
