description: In the computation of multiphase flow with mass transfer, the large disparity between the length and time scale of the mass transfer and the fluid flow demand excessive grid resolution for fully resolved simulation of such flow. We have developed a subscale description for the mass transfer in bubbly flow to alleviate the grid requirement needed at the interface where the mass gets transferred from one side to the other. In this fluid dynamics video, a simulation of the mass transfer from buoyant bubbles is done using a Front Tracking method for the tracking of interface and a subscale description for the transfer of mass from the bubble into the domain. After the mass is transferred from the bubble into the domain, mass is followed by solving an advection-diffusion equation on a relatively coarse Cartesian grid. More detail about the method can be found in our paper. This simulation shows 13 moving bubbles in a periodic domain, 3db X 3db X 48db, where db is the bubble diameter. The grid resolution is 64 X 64 X 1024, which results in about 21 cell across one bubble diameter. The flow non-dimensional governing parameters are Eo = 2.81 and Mo = 4.5 * 10^-7 with density and viscosity ratio of 0.1 and for the mass transfer we have Sc = 60. In the movie, bubbles are colored to show the mass boundary layer thickness, with blue showing a close to zero value and red showing the maximum value. Mass concentration inside the domain is colored from transparent blue for low value, 0, to solid red for high value, 1. Time is non-dimensionalized with sqrt(db/g).

description: After a decade of post-conflict stabilisation and recovery efforts — during which RAMSI played a key role in peacekeeping, policing, justice and economic management — responsibility for international assistance is being handed to bilateral and multilateral donor agencies delivering regular aid and development support. The Australian Government has been clear that this ‘transition’ reflects the success of intervention efforts in supporting ‘recovery’ across several fronts. But has Solomon Islands’ economy yet ‘recovered’ from the disruptions of the tensions? And what do recent patterns of growth mean for Solomon Islands’ future economic development?

description: Grain boundary segregations were investigated by Atom Probe Tomography in an Al-Mg alloy, a carbon steel and Armco\trademark Fe processed by severe plastic deformation (SPD). In the non-deformed state, the GBs of the aluminium alloy are Mg depleted, but after SPD some local enrichment up to 20 at.% was detected. In the Fe-based alloys, large carbon concentrations were also exhibited along GBs after SPD. These experimental observations are attributed to the specific structure of GBs often described as "non-equilibrum" in ultra fine grained materials processed by SPD. The grain boundary segregation mechanisms are discussed and compared in the case of substitutional (Mg in fcc Al) and interstitial (C in bcc Fe) solute atoms.

description: International economic development assistance to Solomon Islands has recently undergone an important ‘transition’. The Regional Assistance Mission to the Solomon Islands (RAMSI) ten-year post-conflict stabilisation intervention is coming to an end, and bilateral and multilateral donors have now taken over key RAMSI functions in economic management. The international community is moving its focus from stabilisation and security towards longer term development needs, under more conventional modalities of support (Coppel 2012).

description: A new two layer hierarchical routing protocol called Cluster Based Hierarchical Routing Protocol (CBHRP) is proposed in this paper. It is an extension of LEACH routing protocol. We introduce cluster head-set idea for cluster-based routing where several clusters are formed with the deployed sensors to collect information from target field. On rotation basis, a head-set member receives data from the neighbor nodes and transmits the aggregated results to the distance base station. This protocol reduces energy consumption quite significantly and prolongs the life time of sensor network. It is found that CBHRP performs better than other well accepted hierarchical routing protocols like LEACH in term of energy consumption and time requirement.

The Price of Peace: Public Finance Institutions and Social Order in Post-Conflict Countries
Creators: name: Haque, Tobias A.
Publisher: name: The Australian National University
Year: 2023

description: What impacts do attempts to reform public finance institutions have on social order in low-income post-conflict countries? International development agencies invest heavily in building and reforming public finance institutions in war-torn countries as part of broader development and state-building efforts. Improvements in the ways revenues are raised, budgets are prepared and executed, and funds flow through government financing systems are assumed to help address conflict pressures, by supporting strengthened state legitimacy via improved economic outcomes and better delivery of public services. The assumed relationship between public finance reform and social order has, however, been subject to little empirical examination and is increasingly challenged by theoretical and empirical literature. Recent evidence suggests that social order in fragile state settings depends more on the enrolment and placation of powerful actors through the distribution of economic rents than on economic growth or the effective delivery of services. In this thesis, I apply an historical institutionalist clustered case study approach to examine the impacts of major public finance reform initiatives on social order in three low-income, post-conflict settings (Solomon Islands over 2003-2014, Timor-Leste over 2000-2015, and Afghanistan over 2001-2021). I utilize Mushtaq Khan's 'political settlements' framework to show that in each case, efforts to reform public finance institutions weakened the capacity of political elites to distribute public sector rents to powerful actors, contributing to disorder and conflict pressures. This led to important second-order effects. Political elites, sensitive to conflict risks, sought to distort, undermine, or selectively apply imported public finance institutions to achieve rent extraction and distribution objectives. Imported public finance institutions thereby came to serve important functions very different from those initially intended. My findings highlight important incompatibilities between established development practice and the conflict mitigation objectives increasingly pursued by international development agencies working in fragile country settings.
Aging in the trap model as a relaxation further away from equilibrium

description: The aging regime of the trap model, observed for a temperature T below the glass transition temperature T_g, is a prototypical example of non-stationary out-of-equilibrium state. We characterize this state by evaluating its "distance to equilibrium", defined as the Shannon entropy difference ΔS (in absolute value) between the non-equilibrium state and the equilibrium state with the same energy. We consider the time evolution of ΔS and show that, rather unexpectedly, ΔS(t) continuously increases in the aging regime, if the number of traps is infinite, meaning that the "distance to equilibrium" increases instead of decreasing in the relaxation process. For a finite number N of traps, ΔS(t) exhibits a maximum value before eventually converging to zero when equilibrium is reached. The time t* at which the maximum is reached however scales in a non-standard way as t* ~ N^(T_g/2T), while the equilibration time scales as N^(T_g/T). In addition, the curves ΔS(t) for different N are found to rescale as ln t/ln t*, instead of the more familiar scaling t/t*.

Solomon Islands

description: "In this paper, I present a political-economy critique of culturally based explanations for uneven development progress in Solomon Islands. I argue that the behaviours frequently blamed for slowing economic development and social progress are primarily driven by perverse material incentives prevailing under existing policy and institutional settings. While various cultural factors doubtlessly influence behaviour, the behaviours that commentators and development practitioners are most concerned about are entirely consistent with traditional economic models emphasising the tendency of individuals to act in their material self-interest. Understanding poor outcomes in Solomon Islands as the result of perverse material incentives facing individuals, rather than a result of the local culture, is more useful from a policy perspective and avoids the unjustified problematising of Solomon Islands culture. By applying this framework, I identify a range of practical policy priorities to ameliorate existing perverse material incentives and accelerate development progress. The paper focuses on the causes of three key development problems facing Solomon Islands: weak political and policy cohesion, poor public administration, and limited private sector development ..." - page 1

description: The internal oxidation of Sn was investigated to understand the oxidation kinetics of monophase CuSn alloys. SnO2 particles were characterized by analytical transmission electron microscopy. The orientation relationship between SnO2 and Cu was determined with a special emphasis on the atomic scale structure of Cu/SnO2 interfaces (misfit dislocations and chemical structure). Habit planes with a pure oxygen plane terminating the SnO2 phase are greatly favored and large misfits promote the growth of plate shaped precipitates.

In this paper, we present the Bit Error Rate (BER) performance of different spreading codes (Walsh-Hadamard code, Orthogonal gold code and Golay complementary sequences) using Forward Error Correction (FEC) of the proposed system. The data is analyzed and is compared among different spreading codes in both coded and uncoded cases. It is found via computer simulation that the performance of the proposed coded system is much better than that of the uncoded system irrespective of the spreading codes and all the spreading codes show approximately similar nature for both coded and uncoded in all modulation schemes.

description: We investigate the emergence and evolution of shape coexistence in the neutron-deficient Lead isotopes within the interacting boson model (IBM) plus configuration mixing with microscopic input based on the Gogny energy density functional (EDF). The microscopic potential energy surface obtained from the constrained self-consistent Hartree-Fock-Bogoliubov method employing the Gogny-D1M EDF is mapped onto the coherent-state expectation value of the configuration-mixing IBM Hamiltonian. In this way, the parameters of the IBM Hamiltonian are fixed for each of the three relevant configurations (spherical, prolate and oblate) associated to the mean field minima. Subsequent diagonalization of the Hamiltonian provides the excitation energy of the low-lying states and transition strengths among them. The model predictions for the $0^{+}$ level energies and evolving shape coexistence in the considered Lead chain are consistent both with experiment and with the indications of the Gogny-EDF energy surfaces.

description: We present velocity dispersion measurements of 20 Local Group stellar clusters (7 < log(age [yrs]) < 10.2) from integrated light spectra and examine the evolution of the stellar mass-to-light ratio, Upsilon_*. We find that the clusters deviate from the evolutionary tracks corresponding to simple stellar populations drawn from standard stellar initial mass functions (IMFs). The nature of this failure, in which Upsilon_* is at first underestimated and then overestimated with age, invalidates potential simple solutions involving a rescaling of either the measured masses or modeled luminosities. A range of possible shortcomings in the straightforward interpretation of the data, including subtleties arising from cluster dynamical evolution on the present day stellar mass functions and from stellar binarity on the measured velocity dispersions, do not materially affect this conclusion given the current understanding of those effects. Independent of further conjectures regarding the origin of this problem, this result highlights a basic failing of our understanding of the integrated stellar populations of these systems. We propose the existence of two distinct initial mass functions, one primarily, but not exclusively, valid for older, metal poor clusters and the other for primarily, but not exclusively, younger, metal rich clusters. The young (log(age [yrs])< 9.5) clusters are well-described by a bottom-heavy IMF, such as a Salpeter IMF, while the older clusters are better described by a top-heavy IMF, such as a light-weighted Kroupa IMF, although neither of these specific forms is a unique solution. The sample is small, with the findings currently depending on the results for four key clusters, but doubling the sample is within reach.

description: Intersubband polaritons are light-matter excitations originating from the strong coupling between an intersubband quantum well electronic transition and a microcavity photon mode. In this paper we study how the Coulomb electron-electron interaction and the Pauli saturation of the electronic transitions affect the physics of intersubband polaritons. We develop a microscopic many-body theory for the physics of such composite bosonic excitations in a microcavity-embedded two-dimensional electron gas. As a first application, we calculate the modification of the depolarization shifts and the efficiency of intersubband polariton-polariton scattering processes.

description: La contribution de l'économie comportementale (EC) consiste à éclairer la compréhension du comportement humain et à informer le processus de conception, d'élaboration et de mise en œuvre des politiques gouvernementales. 
La protection sociale est un exemple concret du champ de développement d'une politique publique sociale. Cet article examine l'apport de l'EC à la consécration de la protection sociale et plus particulièrement à la généralisation de l'assurance maladie obligatoire (AMO) au profit des travailleurs non-salariés (TNS).
À travers l'exploration d'un ensemble d'informations communiquées par les autorités gouvernementales marocaines au titre de la période allant de 2016 à 2020, nous cherchons à mener une réflexion sur l'économie comportementale et à apprécier sa valeur ajoutée sur la performance du système de protection sociale. En effet, l'EC permet de se doter de concepts efficaces susceptibles d'accroitre le nombre des citoyens adhérents à l'AMO et d'assurer ainsi le développement de ce mécanisme de prévoyance sociale.
Les premiers résultats très positifs de ce chantier ont dû être soutenus par des solutions issues de l'économie comportementale comme la proposition d'un choix unique et le recours à des incitations pour contourner les phénomènes comportementaux susceptibles de freiner la généralisation de l'AMO sur une population cible.
Separation of two contributions to the high energy emission of Cygnus X-1: Polarization measurements with INTEGRAL SPI

description: Operational since 2002 on-board the INTEGRAL observatory, the SPI spectrometer can be used to perform polarization measurements in the hard X-ray/soft gamma-ray domain (~ 130 keV - 8 MeV). However, this phenomenon is complex to measure at high energy and requires high fluxes. Cyg X-1 appears as the best candidate amongst the X-ray binaries since it is one of the brightest persistent sources in this energy domain. Furthermore, a polarized component has recently been reported above 400 keV from IBIS data. We have therefore dedicated our efforts to develop the required tools to study the polarization in the INTEGRAL SPI data and have first applied them to 2.6 Ms of Cyg X-1 observations, covering 6.5 years of the INTEGRAL mission. We have found that the high energy emission of Cyg X-1 is indeed polarized, with a mean polarization fraction of 76 % +/- 15 % at a position angle estimated to 42 +/- 3 degrees, for energies above 230 keV. The polarization fraction clearly increases with energy. In the 130-230 keV band, the polarization fraction is lower than 20 %, but exceeds 75 % between 370 and 850 keV, with the (total) emission vanishing above this energy. This result strongly suggests that the emission originates from the jet structure known to emit in the radio domain. The same synchrotron process could be responsible for the emission from radio to MeV, implying the presence of high energy electrons. This illustrates why the polarization of the high energy emission in compact objects is an increasingly important observational objective.

description: Intrarectal infection between men who have sex with men represents a predominant form of human immunodeficiency virus (HIV) transmission in developed countries. Currently there are no adequate small animal models that recapitulate intrarectal HIV transmission. Here we demonstrate that human lymphocytes generated in situ from hematopoietic stem cells reconstitute the gastrointestinal tract of humanized mice with human CD4+ T cells rendering them susceptible to intrarectal HIV transmission. HIV infection after a single intrarectal inoculation results in systemic infection with depletion of CD4+ T cells in gut-associated lymphoid tissue and other pathologic sequela that closely mimics those observed in HIV infected humans. This novel model provides the basis for the development and evaluation of novel approaches aimed at immune reconstitution of human gut-associated lymphoid tissue and for the development, testing, and implementation of microbicides to prevent intrarectal HIV-1 transmission.

description: Traditional network diagnosis methods of Client-Terminal Device (CTD) problems tend to be laborintensive, time consuming, and contribute to increased customer dissatisfaction. In this paper, we propose an automated solution for rapidly diagnose the root causes of network performance issues in CTD. Based on a new intelligent inference technique, we create the Intelligent Automated Client Diagnostic (IACD) system, which only relies on collection of Transmission Control Protocol (TCP) packet traces. Using soft-margin Support Vector Machine (SVM) classifiers, the system (i) distinguishes link problems from client problems and (ii) identifies characteristics unique to the specific fault to report the root cause. The modular design of the system enables support for new access link and fault types. Experimental evaluation demonstrated the capability of the IACD system to distinguish between faulty and healthy links and to diagnose the client faults with 98% accuracy. The system can perform fault diagnosis independent of the user's specific TCP implementation, enabling diagnosis of diverse range of client devices

description: In modern communication system, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as air or cables. A flexible signal modulation scheme is hence essential to wide range of applications based on flexible electronics. Here we report a fully bendable all-graphene modulator circuit with the capability to encode a carrier signal with quaternary digital information for the first time. By exploiting the ambipolarity and the nonlinearity in a graphene transistor, we demonstrated two types of quaternary modulation schemes: 4-ary amplitude-shift keying (4-ASK) and quadrature phase-shift keying (QPSK). Remarkably, 4-ASK and QPSK can be realized with just 1 and 2 all-graphene transistors, respectively, representing a drastic reduction in circuit complexity when compared with conventional digital modulators. In addition, the circuit is not only flexible but also highly transparent (~95% transmittance) owing to their all-graphene design with every component (channel, interconnects, load resistor, and source/drain/gate electrodes) fabricated from graphene films. Taken together, these results represent a significant step toward achieving a high speed communication system that can be monolithically integrated on a flexible and transparent platform.

description: Mean-field models of the mammalian cortex treat this part of the brain as a two-dimensional excitable medium. The electrical potentials, generated by the excitatory and inhibitory neuron populations, are described by nonlinear, coupled, partial differential equations, that are known to generate complicated spatio-temporal behaviour. We focus on the model by Liley {\sl et al.} (Network: Comput. Neural Syst. (2002) 13, 67-113). Several reductions of this model have been studied in detail, but a direct analysis of its spatio-temporal dynamics has, to the best of our knowledge, never been attempted before. Here, we describe the implementation of implicit time-stepping of the model and the tangent linear model, and solving for equilibria and time-periodic solutions, using the open-source library PETSc. By using domain decomposition for parallelization, and iterative solving of linear problems, the code is capable of parsing some dynamics of a macroscopic slice of cortical tissue with a sub-millimetre resolution.

description: We investigate stationary hidden Markov processes for which mutual information between the past and the future is infinite. It is assumed that the number of observable states is finite and the number of hidden states is countably infinite. Under this assumption, we show that the block mutual information of a hidden Markov process is upper bounded by a power law determined by the tail index of the hidden state distribution. Moreover, we exhibit three examples of processes. The first example, considered previously, is nonergodic and the mutual information between the blocks is bounded by the logarithm of the block length. The second example is also nonergodic but the mutual information between the blocks obeys a power law. The third example obeys the power law and is ergodic.

Investigation of steady-state and time-dependent luminescence properties of colloidal InGaP quantum dots

description: Quantum dots play a promising role in the development of novel optical and biosensing devices. In this study, we investigated steady-state and time-dependent luminescence properties of InGaP/ZnS core/shell colloidal quantum dots in a solution phase at room temperature. The steady state experiments exhibited an emission maximum at 650 nm with full width at half maximum of ~ 85 nm, and strong first-excitonic absorption peak at 600 nm. The time-resolved luminescence measurements depicted a bi-exponential decay profile with lifetimes of τ1\sim 47 ns and τ 2\sim 142 ns at the emission maximum. Additionally, luminescence quenching and lifetime reduction due to resonance energy transfer between the quantum dot and an absorber are demonstrated. Our results support the plausibility of using these InGaP quantum dots as an effective alternative to highly toxic conventional Cd or Pb based colloidal quantum dots for biological applications.

description: [abridged] Aims. The aim of this paper is to assess the impact of the interstellar medium (ISM) physics on Lyman-alpha (Lya) radiation transfer and to quantify how galaxy orientation with respect to the line of sight alters observational signatures. Methods. We compare the results of Lya radiation transfer calculations through the ISM of a couple of idealized galaxy simulations with different ISM models. Results. First, the small-scale structuration of the ISM plays a determinant role in shaping a galaxys Lya properties.The artificially warm, and hence smooth, ISM of G1 yields an escape fraction of 50 percent at the Lya line center, and produces symmetrical double-peak profiles. On the contrary, in G2, most young stars are embedded in thick star-forming clouds, and the result is a 10 times lower escape fraction. G2 also displays a stronger outflowing velocity field, which favors the escape of red-shifted photons, resulting in an asymmetric Lya line. Second, the Lya properties of G2 strongly depend on the inclination at which it is observed: From edge-on to face-on, the line goes from a double-peak profile with an equivalent width of -5 Angstrom to a 15 times more luminous red-shifted asymmetric line with EW 90 Angstrom. Conclusions. Lya radiation transfer calculations can only lead to realistic properties in simulations where galaxies are resolved into giant molecular clouds, putting these calculations out of reach of current large scale cosmological simulations. Finally, we find inclination effects to be much stronger for Lya photons than for continuum radiation. This could potentially introduce severe biases in the selection function of narrow-band Lya emitter surveys, which could indeed miss a significant fraction of the high-z galaxy population.

description: The use of polarized $^3$He ions in storage rings opens a new window to investigate nuclear forces, because the spin-dependent part of the differential cross section of the observed reactions must stem in first order from the neutron spin. Thus, nuclear polarized $^3$He$^{2+}$ beams can be regarded as an ideal substitute for polarized neutron beams. Polarized $^3$He ions were used in the 1960’s, but either the nuclear polarization and/or the usable intensity of the corresponding ion sources was rather small. Since then, several groups around the world have been working on the realization of an efficient polarized $^3$He ion source for injection into storage rings. Current concepts are based on the rapid ionization of optically-pumped polarized $^3$He gas with polarization values up to 0.8. Nevertheless, most of the different ionization processes tested so far result in large polarization losses.A new approach at the Institute for Nuclear Physics in the Research Center Jülich promises to overcome the recent limitations with an intense (>10 μA) polarized $^3$He$^{1+}$ beam with a polarization up to P ~ 0.9 that can be used for stripping injection to feed storage rings. The method itself is similar to “optical pumping”, but instead of laser beams single radio-wave pulses are used to induce transitions within the hyperfine substates in the Zeeman region of a $^3$He$^{1+}$ beam at 4 keV. The corresponding photons are coherent and monochromatic, and the induced transitions at an energy level of 10$^{−8}$ eV interfere with each other. Based on this phenomenon, the three substates of the F = 1 state can be pumped into a single substate with $m_F =$ +1 or -1. The corresponding polarization will be measured after acceleration to about 100 MeV due to the known analyzing powers of elastic scattering on protons with an existing polarimeter behind the cyclotron JULIC. In principle, this technique can be expanded to other ions, even heavy ions, and may open the door for a new generation of polarized ion sources or polarized fuel, thus increasing the energy output of future fusion reactors.

description: We perform time- and angle-resolved photoemission spectroscopy of a prototypical topological insulator Bi$_2$Se$_3$ to study the ultrafast dynamics of surface and bulk electrons after photo-excitation. By analyzing the evolution of surface states and bulk band spectra, we obtain their electronic temperature and chemical potential relaxation dynamics separately. These dynamics reveal strong phonon-assisted surface-bulk coupling at high lattice temperature and total suppression of inelastic scattering between the surface and the bulk at low lattice temperature. In this low temperature regime, the unique cooling of Dirac fermions in TI by acoustic phonons is manifested through a power law dependence of the surface temperature decay rate on carrier density.
