description: The propagation of traffic congestion along roads is a commonplace nonlinear phenomenon. When many roads are connected in a network, congestion can spill from one road to others as drivers queue to enter a congested road, creating further nonlinearities in the network dynamics. This paper considers the node model problem, which refers to methods for solving for cross-flows when roads meet at a junction. We present a simple hybrid dynamic system that, given a macroscopic snapshot of the roads entering and exiting a node, intuitively models the node's throughflows over time. This dynamic system produces solutions to the node model problem that are equal to those produced by many popular node models without intuitive physical meanings. We also show how the earlier node models can be rederived as executions of our dynamic system. The intuitive physical description supplied by our system provides a base for control of the road junction system dynamics, as well as the emergent network dynamics.

Reconfiguring a Metropolitan Region: Corporate Architectural Typologies in Portland, Oregon
Creators: Irazabal Zurita, Clara E.
Publisher: name: Columbia University
Year: 2002
Subjects: City planning

description: This presentation focuses on the tensions between different architectural traditions in Portland, a metropolitan region contained within an urban boundary. I examine two types in the production of recent residential and corporate architecture. Through the study of specific examples, I explore the intersection between urban planning premises and architectural physicality in the context of Portland‘s planning culture. I investigate how these two architectural types have originated as products of, or reactions to, several of the main planning discourses in the city. The result is a spatial environment where conflicting planning views are reflected in contrasting architectural typologies, resulting in reconfigurations of both the region and its building traditions, and where the political and/or theoretical disputes over planning concepts are localized, i.e., are assigned specific, often contrasting, spatial meanings and forms.

description: A BEC interacting with an optical field via a feedback mirror can be a realisation of the quantum Hamiltonian Mean Field (HMF) model, a paradigmatic model of long-range interactions in quantum systems. We demonstrate that the self-structuring instability displayed by an initially uniform BEC can evolve as predicted by the quantum HMF model, displaying quasiperiodic "chevron" dynamics for strong driving. For weakly driven self-structuring, the BEC and optical field behave as a two-state quantum system, regularly oscillating between a spatially uniform state and a spatially periodic state. It also predicts the width of stable optomechanical droplets and the dependence of droplet width on optical pump intensity. The results presented suggest that optical diffraction-mediated interactions between atoms in a BEC may be a route to experimental realisation of quantum HMF dynamics and a useful analogue for studying quantum systems involving long-range interactions.

description: The identification of orbital angular momentum (OAM) as a fundamental property of a beam of light nearly twenty-five years ago has led to an extensive body of research around this topic. The possibility that single photons can carry OAM has made this degree of freedom an ideal candidate for the investigation of complex quantum phenomena and their applications. Research in this direction has ranged from experiments on complex forms of quantum entanglement to the interaction between light and quantum states of matter. Furthermore, the use of OAM in quantum information has generated a lot of excitement, as it allows for encoding large amounts of information on a single photon. Here we explain the intuition that led to the first quantum experiment with OAM fifteen years ago. We continue by reviewing some key experiments investigating fundamental questions on photonic OAM and the first steps into applying these properties in novel quantum protocols. In the end, we identify several interesting open questions that could form the subject of future investigations with OAM.

description: We report the coexistence and properties of stable compact localized states (CLSs) and discrete solitons (DSs) for nonlinear spinor waves on a flatband network with spin-orbit coupling (SOC). The system can be implemented by means of a binary Bose-Einstein condensate loaded in the corresponding optical lattice. In the linear limit, the SOC opens a minigap between flat and dispersive bands in the system's bandgap structure, and preserves the existence of CLSs at the flatband frequency, simultaneously lowering their symmetry. Adding onsite cubic nonlinearity, the CLSs persist and remain available in an exact analytical form, with frequencies which are smoothly tuned into the minigap. Inside of the minigap, the CLS and DS families are stable in narrow areas adjacent to the FB. Deep inside the semi-infinite gap, both the CLSs and DSs are stable too.

description: The magnetic fields, activity and dynamos of young solar-type stars can be empirically studied using time-series of spectropolarimetric observations and tomographic imaging techniques such as Doppler imaging and Zeeman Doppler imaging. In this paper we use these techniques to study the young Sun-like star EK Draconis (Sp-Type: G1.5V, HD 129333) using ESPaDOnS at the Canada-France-Hawaii Telescope and NARVAL at the Tèlescope Bernard Lyot. This multi-epoch study runs from late 2006 until early 2012. We measure high levels of chromospheric activity indicating an active, and varying, chromosphere. Surface brightness features were constructed for all available epochs. The 2006/7 and 2008 data show large spot features appearing at intermediate-latitudes. However, the 2012 data indicate a distinctive polar spot. We observe a strong, almost unipolar, azimuthal field during all epochs that is similar to that observed on other Sun-like stars. Using magnetic features, we determined an average equatorial rotational velocity, Ω_eq, of 2.50 +/- 0.08 rad/d. High levels of surface differential rotation were measured with an average rotational shear, ΔΩ, of 0.27 +0.24-0.26 rad/d. During an intensively observed 3-month period from December 2006 until February 2007, the magnetic field went from predominantly toroidal ( approx. 80%) to a more balanced poloidal-toroidal (approx. 40-60%) field. Although the large-scale magnetic field evolved over the epochs of our observations, no polarity reversals were found in our data.

Assignment of VAT Revenue and Decentralization of its Administration: The case of Ethiopia
Creators: name: Emiru, Alazar
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2009

description: This project tries to look at decentralization of VAT revenue and administration to sub national governments in Ethiopia in light of the international practices. It used individual in-depth interview to collect primary data from Ethiopian revenue and custom Authority (ERCA), Addis Ababa regional city administration tax office and ministry of finance and economic development (MOFED). The methods used for analysis were both qualitative and quantitative. The project discusses the problems in connection with decentralization of VAT administration and assignment of VAT revenue. The project suggests that decentralization of VAT administration needs capable and autonomous regional government and strong central government that could monitor and evaluate decentralization; and the assignment of VAT revenue also needs the central governments' follow up to minimize the distortions and should be applied in consistent with the constitution.

description:
A high abundance of arthropod cuticles in the fossil record are well preserved, even at the microstructural level. The age of these fossils is usually constrained chronostratigraphically, but incorporation of radioactive trace elements during fossilization makes cuticles also amenable to radiometric dating. Our study aimed to assess to what extent the current mineralogical, chemical, and isotopic composition of fossil cuticles can provide a record of the long-term diagenetic evolution.

We combined electron microprobe element mapping, Raman spectroscopy, and laser ablation ICP-MS analyses to study the exoskeleton of a fossil raninoid crab from Chattian (Late Oligocene) strata of the Doberg (near Bünde, NW Germany). The investigated exocuticle had been replaced by apatite, while the endocuticle mostly consists of uraniferous calcite (up to 500 ppm U), yielding a LA-ICPMS U-Pb age of 17.5 ± 1.4 Ma (Burdigalian, Late Early Miocene). This age is consistent with the view that the present mineralogy formed millions of years after the death of the individual. A Late Early Miocene age, however, was also obtained from another Oligocene raninoid crab cuticle from Bodenburg (100 km to the ESE), suggesting a possible regional geological significance of this age within the Lower Saxony Tectogene.

In conclusion, fossilized arthropod cuticle can remain a closed U-Pb system over geologic time scales. However, the fossil cuticles were altered by distinct geological events affecting the diagenetic conditions in depositional basins, such as, for instance, an increased fluid flow. The U-Pb system of arthropod fossil cuticles might allow for tracing these long-term diagenetic processes.

description: The performance of coastal altimetry over a wide continental shelf is assessed using multiple-year ocean current observations by moored Acoustic Doppler Current Profilers (ADCP) and high frequency (HF) radar on the West Florida Shelf. Across track, surface geostrophic velocity anomalies, derived from the XTRACK along-track sea level anomalies are compared with the near surface current vector components from moored ADCP observations at mid shelf. The altimeter derived velocity anomalies are also directly compared with the HF radar surface current vector radial components that are aligned perpendicular to the satellite track. Preliminary results indicate the potential usefulness of the along-track altimetry data in contributing to descriptions of the surface circulation on the West Florida Shelf and the challenges of such applications. On subtidal time scales, the root mean square difference (rmsd) between the estimated and the observed near surface velocity component anomalies is 8 11 cms-1, which is about the same magnitude as the standard deviations of the velocity components themselves. Adding a wind-driven Ekman velocity component generally helps to reduce the rmsd values.

description: IMPORTANT DEADLINES Submission of Full Paper: January 15th, 2021.
 Review Process Ends: until June 15th, 2021.
 Special Issue publication (expected): until September, 2021. SPECIAL ISSUE THEME Insights from behavioral sciences are reshaping the architecture of choice design. Nudges are small changes in supposedly irrelevant features in the choice framing to enhance the best option, without removing the other set of options, to promote the best self-interest of the individual (Thaler & Sunstein, 2008) . A nudge is neutral in the sense that individuals can opt-out of the nudge incentive without difficulty or relevant cost. However, in practice, nudges are strongly efficient to affect the decision-making process and, consequently, the final well-being level of the individuals (hopefully for the best). Currently, nudge initiatives are increasingly widespread. They are being used in very different ways and at different levels throughout the world to enhance the effectiveness of interventions to promote individual and social welfare (see, for instance, Behavioural Insights Team, 2018; John et al., 2020; Lehner et al., 2016; Lourenço et al., 2016; White, 2019; Whitehead et al., 2014). In this special call for papers, we aim to see how insights from behavioral science can help researchers and policymakers to understand the potential of choice architecture and nudging to respond to various challenges in management. For this special issue, we welcome submissions of all areas of management that address nudging or choice architecture.

description: Due to the low accuracy of object detection and recognition in many intelligent surveillance systems at nighttime, the quality of night images is crucial. Compared with the corresponding daytime image, nighttime image is characterized as low brightness, low contrast and high noise. In this paper, a bio-inspired image enhancement algorithm is proposed to convert a low illuminance image to a brighter and clear one. Different from existing bio-inspired algorithm, the proposed method doesn't use any training sequences, we depend on a novel chain of contrast enhancement and denoising algorithms without using any forms of recursive functions. Our method can largely improve the brightness and contrast of night images, besides, suppress noise. Then we implement on real experiment, and simulation experiment to test our algorithms. Both results show the advantages of proposed algorithm over contrast pair, Meylan and Retinex.

description:
Rocks exposed in alkaline magmatic complexes and associated rare metal deposits are a product of multistage formation. Petrographic, mineralogical and geochemical characteristics suggest that post-magmatic metasomatic mineral reactions triggered by high flux of magmatic volatiles are very common. Release of magmatic fluids and rock permeability are pressure dependent, which may exert a depth control on metasomatic reactions altering intrusion related vertical magmatic zonation along the intrusive conduit. Fenites attest to fluid release to the wall rocks. High permeability in the contact to the wall rock causes intensive fluid-rock interaction and metasomatic products observed across the contact at a given exposure level are the integrated product of fluid flux with a significant density driven vertical advective component. Alkaline rocks may thus reflect input from various mantle and crustal sources situated at lower levels of the intrusive system.

Here, we present results of a mineralogical and isotope geochemical investigation of samples from the complexes of Kovdor and Iivaara (Kola Alkaline Province), which are considered to represent different levels in both intrusive alkaline systems. Peridotitic and ijolitic rocks show substantial subsolidus mineral reactions. In both cases mineralogical as well as Sr and Nd isotopic signatures suggest a complex and multistage post-magmatic metasomatic evolution mainly driven by magmatic fluids, in which, however, input from the wall rocks across the contact into the complex cannot be ruled out.

description: Recently interesting observations on electron vortex beams, which have angular momentum about the center of the vortex beams, have been made. We have shown that the basic features of the electron vortex beams in a uniform magnetic field are understandable by using the classical motions of electrons. We have constructed a classical vortex-like motion by the collective motion of individual electrons in their cyclotron motions with a constant canonical angular momentum in the symmetric gauge, which models electron vortex beams, in a uniform magnetic field. With this model the various properties of circulating currents and the relation between energy and kinetic angular momentum in the electron vortex beams are well explained. We have also shown that the mismatch between the centers of the electron vortex beam and the classical cyclotron orbits naturally induces the parallel axis theorem and also the time-varying kinetic angular momentum of the electron vortex beam for certain distributions of classical electrons.

description: Highly disordered superconductors, in the magnetic-field-driven insulating state, can show discontinuous current-voltage characteristics. Electron overheating has been shown to give a consistent description of this behavior, but there are other, more exotic, explanations including a novel, superinsulating state and a many-body localized state. We present AC-DC crossed-measurements, in which the application of a DC voltage is applied along our sample, while a small AC voltage is applied in the transverse direction. We varied the DC voltage and observed a simultaneous discontinuity in both AC and DC currents. We show that the inferred electron-temperature in the transverse measurement matches that in the longitudinal one, strongly supporting electron overheating as the source of observed current-voltage characteristics. Our measurement technique may be applicable as a method of probing electron overheating in many other physical systems, which show discontinuous or non-linear current-voltage characteristics.
The Effects Of Outsourcing Service On Institution Performance: (The Case Of Addis Ababa University)

description: The research examined the effects of outsourcing on the performance of organizations. Substantial uncertainties remain as to how outsourcing practices affect organizational outcomes, whether some practices have stronger effects than others, and whether complementary or synergies among such practices can further enhance organizational performance. The objectives of the study were to identify the reasons for outsourcing, to measure the effects of the outsourced activities on the organizations performance and to determine the key benefits gained and challenges faced from outsourcing noncore business functions. The methodology was based on Descriptive survey method with the procedures of quantitative and qualitative (mixed method) research designs to analyze the data collected from the selected campuses. The research employed the use of questionnaires which included the rating scale which was easier to administer to the respondents and also saved time. The key factors that influenced the choice to outsource a function/activity by management were to allow staff to concentrate on the core activities and to reduce cost. It also emerge that, the key benefits gained from both security and cleaning functions was to focus on core functions, reduce cost, increase flexibility and improve organizational performance. On the other hand the challenges faced while outsourcing those functions was the misalignment between the requirement of the AAU and the service provider, AAU did not set an evaluation criteria to measure the performance of the service provider and the challenges related to controlling the staffs during working hour. So using the above issues Setting well formulated service level agreement (SLA) in which a company helps to evaluate the service of a vendor and good service can be easily differentiated from bad service. The service provider needs to control the staffs during working hour using different controlling mechanisms such as giving rewards to staffs who are working properly. But the university also must establish formal groups in each campus who control and report the service provided by the service provider

description:
The aluminum oxide (Al2O3) corundum is of high economic interest, not least because of its rare gemstone varieties sapphire and ruby. Geochemical analyses are helpful to gain a better understanding of the geographical origin and distribution of corundum. In addition to trace elements, O-isotopes (δ18O) are a powerful tool to identify provenance of gem-quality corundum. High spatial resolution analysis by secondary ionization mass spectrometry (SIMS) plays an essential role for this because it can identify intracrystalline heterogeneity and thus more reliably identify genetic processes. However, accurate SIMS analysis requires suitable matrix-matched reference materials. Some in-house reference materials for corundum are currently in use by different SIMS labs, but these materials generally lack comprehensive chemical and isotopic characterization. Moreover, crystal-orientation effects can create bias in SIMS analysis. Therefore, it is timely to develop appropriate matrix-matched reference materials for SIMS analysis of corundum.

We have investigated O-isotopic homogeneity and composition of a synthetic laser ruby single-crystal. A rod of it was cut symmetrically from the interior to the rim and analyzed in bulk by laser-fluorination technique in two different laboratories. A preliminary average value of δ18O= +18.3‰ is reported, with no systematic variability across the rod. An adjacent slice of the rod was sectioned in four prominent crystallographic orientations confirmed by EBSD. SIMS results show homogeneous O-isotopic values independent of crystallographic orientation (2SD = 0.18‰ in δ18O, n = 4, six measurements on each orientation). Besides O-isotopes, abundances and homogeneity of key trace elements will be characterized by electron microprobe and SIMS.
The African Court's Interpretation of Article 56(6) of the African Charter: How Evidence Assessment has Complicated Access to the Court

description: This presentation highlights a draft chapter of my doctoral thesis that examines the evidentiary practices of the African Court on Human and Peoples’ Rights in determining admissibility of applications and how these practices have impacted the Court’s accessibility. It specifically interrogates how the Court assesses evidence in determining whether there is compliance with one of the seven admissibility conditions, namely, the requirement (in article 56(6) of the African Charter on Human and Peoples’ Rights) to file applications within reasonable time after exhaustion of local remedies. Through a temporal analysis of the Court’s caselaw from 2013 to 2022, the paper demonstrates that the African Court’s earlier case law (2013-2018) adopted a flexible approach to evidence questions in determining reasonableness of time taken to file cases but has adopted a rigid approach in the recent past (2019-2022). The paper shows that there are unique challenges that prospective applicants face in accessing the Court and this stricter approach to evidence in determining whether applications have been filed timeously has only compounded these access challenges. This shift in the Court’s approach to evidence has resulted in more cases being declared inadmissible on account of undue delay in approaching the Court. Even with the two distinct evidentiary approaches, the paper shows that the Court has in some instances oscillated between its initial flexible approach to evidence and the more recent stricter approach, resulting in inconsistencies in the decisions of the Court. To address these negative developments in the jurisprudence of the Court, the paper concludes by exploring some alternatives to the Court’s stricter approach to evidence in establishing compliance with article 56(6) of the African Charter and makes suggestions on how to address inconsistencies in the Court’s decisions on this admissibility condition.

The Limpopo Belt in southern Africa represents a high-grade gneiss terrane located between the Kaapvaal Craton to the south and the Zimbabwe Craton to the north, and is subdivided into 3 zones: (i) Northern Marginal Zone (reworked part of the Zimbabwe Craton), (ii) Southern Marginal Zone (reworked part of the Pietersburg Block, forming the northern edge of the Kaapvaal Craton), (iii) Central Zone (a polymetamorphic gneiss terrane in between). Results of combined U-Pb dating and Hf isotope analyses of zircon grains from ca. 30 granitoids (TTG’s, sanukitoids, biotite granite, hybride granites) from the Pietersburg Block, Southern Marginal Zone and Central Zone indicate that most granitoids were formed periodically during the Meso- to Neoarchean between 2.97 and 2.62 Ga (from south to north), and plot on a unique crustal array with 176Lu/177Hf = 0.002. This array and the geological-geographic background suggest emplacement of granitoids from different sources (slab melting, enriched mantle wedge and minor crust) over a period of ca. 350 Ma, most likely during successive closure of wide oceanic basin (>10.000 km[1]) located between the Zimbabwe and proto-Kaapvaal Craton. Opening of this basin started ca. 70 Ma earlier, as suggested by Hf model ages of ca. 3.05 Ga, and closure by continent collision occurred at 2.62 Ga. We note that the derived timing for Archean ocean formation and closure is similar to that of modern Wilson cycles (ca. 340 Ma[2]).

Violence and Desire in the Tropics: Libidinal Politics in the Putumayo Writings of Roger Casement

description: In 1910 the British Foreign Office tasked Roger Casement, then-British Consul-General in Rio de Janeiro, with investigating reports of forced labor and systemic violence in the wild rubber extraction zone of the Putumayo. Published the following year, Casement’s official account accused Peruvian and Colombian rubber extractors of exploiting indigenous labor through abduction, torture, sexual violence, and murder. This paper probes the relationships between economic logics of labor and extraction and these spectacular extremes of violence, comparing extractors’ acts with Casement’s own political writings. Individual acts of violence in the Putumayo, while apparently anti-economic in their destruction of natural and indigenous life, ideologically appropriated all indigenous production and reproduction to the extractive system. Meanwhile, Casement’s private diaries from his expedition suggest that homoerotic desire and Irish nationalistic sentiment structured his sympathy for indigenous victims, which took public form in his imaginations of civilized rescue. I argue that rubber violence and Casement’s colonial humanitarianism both channeled individual desires into material and political forms, exemplifying the mutual production of desire and domination in early twentieth-century colonialism.

description: The vapor-liquid equilibrium (VLE) of the Mie potential, where the dispersive exponent is constant (m = 6) while the repulsive exponent n is varied between 9 and 48, is systematically investigated by molecular simulation. For systems with planar vapor-liquid interfaces, long-range correction expressions are derived, so that interfacial and bulk properties can be computed accurately. The present simulation results are found to be consistent with the available body of literature on the Mie fluid which is substantially extended. On the basis of correlations for the considered thermodynamic properties, a multicriteria optimization becomes viable. Thereby, users can adjust the three parameters of the Mie potential to the properties of real fluids, weighting different thermodynamic properties according to their importance for a particular application scenario. In the present work, this is demonstrated for carbon dioxide for which different competing objective functions are studied which describe the accuracy of the model for representing the saturated liquid density, the vapor pressure and the surface tension. It is shown that models can be found which describe simultaneously the saturated liquid density and vapor pressure with good accuracy, and it is discussed to what extent this accuracy can be upheld as the model accuracy for the surface tension is further improved.

description:
Accurate determination of denudation rates is crucial for the quantification of Earth surface processes like soil formation and the consumption of CO2 during silicate weathering. In situ 10Be is the most widely used proxy to quantify denudation rates over millennial timescales, but this system is severely limited in settings where quartz is absent. In contrast, the meteoric cosmogenic 10Be/9Be ratio is independent of quartz presence, but one important parameter that must be known is the 9Be concentration ([9Be]) of the underlying parental bedrock. In lithologically homogenous catchments, an average upper continental crust 9Be value is commonly assumed.

However, this approach may not be appropriate in the lithologically heterogeneous catchments that we encountered along a N-S (26°S to 38°S latitude) gradient in Chile. By sampling ~100 hand-sized pebbles per catchment from the riverbed near the catchment mouth, we investigated the variability in [9Be] of different rock types from each catchment, and calculated area-weighted mean parental [9Be] via a combination with the distribution of lithologies in the catchments. We assessed the consistency of denudation rates calculated from the meteoric 10Be/9Be (Dmet) against denudation rates derived from the in situ technique (Dinsitu).

Current data from 7 catchments shows that Dmet are in very good agreement with previously published Dinsitu along Chile: a peak in D of around 0.25 mm/yr at 34°S latitude, and consistent decreases to <0.1 mm/yr in N and S directions was reproduced. This supports the versatility of the meteoric 10Be/9Be proxy and encourages its application in catchments containing multiple lithologies.

Additive Deformations of Hopf Algebras

description: Additive deformations of bialgebras in the sense of Wirth are deformations of the multiplication map of the bialgebra fulfilling a compatibility condition with the coalgebra structure and a continuity condition. Two problems concerning additive deformations are considered. With a deformation theory a cohomology theory should be developed. Here a variant of the Hochschild cohomology is used. The main result in the first partad of this paper is the characterization of the trivial deformations, i.e. deformations generated by a coboundary. Starting with a Hopf algebra, one would expect the deformed multiplications to have some analogue of the antipode, which we call deformed antipodes. We prove, that deformed antipodes always exist, explore their properties, give a formula to calculate them given the deformation and the antipode of the original Hopf algebra and show in the cocommutative case, that each deformation splits into a trivial part and into a part with constant antipodes.

description:
Previous bulk sulfur isotope measurements of Eoarchean peridotites from south of the Isua Supracrustal Belt in southern West Greenland have revealed evidence for the presence of recycled surface material in the form of nonzero Δ33S values [1]. In order to confirm these results, identify potential heterogeneity related to multiple sulfur sources, and confirm the Eoarchean origins of the sulfides in these rocks, we combined petrography and mineral chemistry with in-situ multiple sulfur and lead isotope analyses of sulfide minerals via SIMS. Sulfides measured by SIMS were found to be composed primarily of pentlandite and pyrrhotite, with some pentlandite-like compositions consistent with horomanite, which is crystallographically distinct from pentlandite. Our in-situ isotope results confirm the existence of predominantly sediment-derived (positive Δ33S) material recycled from Earth’s surface in these rocks. Average SIMS Δ33S results for measured samples were generally in good agreement with previously measured bulk rock data. The lead isotope compositions confirm an Eoarchean age of the sulfides and show the typical high-µ signature that is observed in other Eoarchean rocks from the area [2]. We observe that highly unradiogenic 207Pb/206Pb isotope ratios in some sulfides plot close to the least radiogenic Pb isotope compositions measured in galenas from Isua.
