description: One of the key applications for the emerging quantum simulators is to emulate the ground state of many-body systems, as it is of great interest in various fields from condensed matter physics to material science. Traditionally, in an analog sense, adiabatic evolution has been proposed to slowly evolve a simple Hamiltonian, initialized in its ground state, to the Hamiltonian of interest such that the final state becomes the desired ground state. Recently, variational methods have also been proposed and realized in quantum simulators for emulating the ground state of many-body systems. Here, we first provide a quantitative comparison between the adiabatic and variational methods with respect to required quantum resources on digital quantum simulators, namely the depth of the circuit and the number of two-qubit quantum gates. Our results show that the variational methods are less demanding with respect to these resources. However, they need to be hybridized with a classical optimization which can converge slowly. Therefore, as the second result of the paper, we provide two different approaches for speeding the convergence of the classical optimizer by taking a good initial guess for the parameters of the variational circuit. We show that these approaches are applicable to a wide range of Hamiltonian and provide significant improvement in the optimization procedure.

description: On 1 May 2004, EU made a historical enlargement by expanding from 15 to 25 members, and with another enlargement in 2007, EU is now a union of 27 member states. Following the new member states accession to the EU the next challenge for them is joining European Monetary Union and introducing the euro as a national legal currency. This thesis concentrated on the analysis on how the new member states handle the process of joining the Euro-zone with the main objective to examine whether there are any possible lessons that Croatia can apply to its EMU integration path. The thesis is mainly focused on analysing the Slovenian EMU integration process, as this member state has been identified by the Croatian Authorities and Croatian National Bank as the one whose experience Croatia should try to follow. The central questions that are discussed are weather Croatia is economically and politically capable to follow the Slovenian example, and, on the other side, weather the Slovenian example is the best one to follow i.e. should Croatia introduce euro by using the quick EMU entry strategy as Slovenia did. In order to answer those questions thesis focused on analysing and explaining different strategies for euro adoption chosen by the new member states with special emphasis on the strategy of quick EMU entry approach chosen by Slovenia. The thesis also concentrated on analysing the Slovenian political and economical path from Yugoslavia to the EU and especially on its economic performance and key economic indicators prior to introducing euro. Finally, with the aim to compare the economic performance between Slovenia and Croatia and define similarities/differences in their transition and EU accession process, the thesis gave a detailed overview of the Croatian current economical and political situation. After brief analysis of all pros and cons of an early euro adoption, the thesis concluded that following the experiences of small sized countries with opened economies and strong trade orientation towards the countries of the Euro-zone, such Slovenia is, would be a comprehensive and logical strategy for Croatia. Early euro adoption would provide more benefits than costs for Croatian economy and society in general. The thesis also concluded that Croatia should face no major problems when it comes to fulfilling most of the Maastricht criterion on time, in order to be able to adopt the euro in the shortest possible period as Slovenia did. However, the thesis also highlighted that in order to do so Croatia has to put a serious emphasis on improving certain aspects of its current macroeconomic situation, in particular the one concerning the percentage of state sector deficit in the GDP and the size of public debt.
The Inner Caustics of Cold Dark Matter Halos

description: We prove that a flow of cold collisionless particles from all directions in and out of a region necessarily forms a caustic. A corollary is that, in cold dark matter cosmology, galactic halos have inner caustics in addition to the more obvious outer caustics. The outer caustics are fold catastrophes located on topological spheres surrounding the galaxy. To obtain the catastrophe structure of the inner caustics, we simulate the infall of cold collisionless particles in a fixed gravitational potential. The structure of inner caustics depends on the angular momentum distribution of the infalling particles. We confirm a previous result that the inner caustic is a "tricusp ring" when the initial velocity field is dominated by net overall rotation. A tricusp ring is a closed tube whose cross section is a section of an elliptic umbilic catastrophe. However, tidal torque theory predicts that the initial velocity field is irrotational. For irrotational initial velocity fields, we find the inner caustic to have a tent-like structure which we describe in detail in terms of the known catastrophes. We also show how the tent caustic transforms into a tricusp ring when a rotational component is added to the initial velocity field.

description: This booklet that has caught your attention contains basic information about the AHEAD project sponsored by the EU’s TEMPUS grant. This project was carried out between University of Zagreb (and other Croatian partners) and four EU-based universities. The project was very ambitious and it is my pleasure to state that the great majority of the objectives were carried out with high quality during the 3 years project time span. The main results of the AHEAD project can be found in this booklet, and I would like to mention just a few of them: • A new MBA training started in Zagreb with international recognition • 61 subjects of 3 BSc/MSc trainings were reviewed and modified, • a study was created in order to determine the short – and long – term expert demand of the Croatian national economy, • computers, equipment and modern textbooks were purchased from European grant and • finally a personal note: it was spectacular to see the rapid development of University of Zagreb and generally the whole Croatia during the last 3 years. If our project contributed just a little bit to it, the effort certainly was worthwhile.
Redshift-Independent Distances to Type Ia Supernovae

description: We describe a procedure for accurately determining luminosity distances to Type Ia supernovae (SNe Ia) without knowledge of redshift. This procedure, which may be used as an extension of any of the various distance determination methods currently in use, is based on marginalizing over redshift, removing the requirement of knowing $z$ a priori. We demonstrate that the Hubble diagram scatter of distances measured with this technique is approximately equal to that of distances derived from conventional redshift-specific methods for a set of 60 nearby SNe Ia. This indicates that accurate distances for cosmological SNe Ia may be determined without the requirement of spectroscopic redshifts, which are typically the limiting factor for the number of SNe that modern surveys can collect. Removing this limitation would greatly increase the number of SNe for which current and future SN surveys will be able to accurately measure distance. The method may also be able to be used for high-$z$ SNe Ia to determine cosmological density parameters without redshift information.

description: Let ${\mathcal C}$ be a proper minor-closed family of graphs. We present a randomized algorithm that given a graph $G \in {\mathcal C}$ with $n$ vertices, finds a simple cycle of size $k$ in $G$ (if exists) in $2^{O(k)}n$ time. The algorithm applies to both directed and undirected graphs. In previous linear time algorithms for this problem, the runtime dependence on $k$ is super-exponential. The algorithm can be derandomized yielding a $2^{O(k)}n\log n$ time algorithm.

description: Crop producers have numerous marketing and risk management tools available. Research relating producers’ risk attitudes to their use of these tools has produced mixed results, and most studies focus on individual tools to the neglect of complementarities among them. Hence, little is known about the proportion in which these tools are used, e.g., the percentage of the crop that is forward sold as opposed to hedged. This study identifies some factors, including risk attitude, that impact the proportion of corn producers’ sales through spot markets, futures and options, and forward and production contracts using complementary survey and accounting data.

We present evidence on the impact of individual as well as regional characteristics on changes in fat, protein, alcohol and cigarette consumption, and on diversity of diet. The results from a dynamic empirical model suggest that among microeconomic determinants, initial levels of consumption, gender, holding a university degree, and having access to a garden plot have a significant impact on the changes in consumption behavior in Russia. Regarding the macroeconomic variables, economic growth has a significant impact on changes in fat and protein consumption and on alcohol use, while unemployment changes significantly impact protein intake, alcohol consumption and the diversity of diet.

description: Trade liberalization has been promoted by the World Bank and IMF based on the argument that openness to trade will contribute to economic growth and development. More specifically, trade liberalization was expected to reduce poverty and improve food availability for local consumption, and thereby contributing to the reduction of malnutrition and to the overall efforts of food security of a nation. Despite the lack of consensus, most developing countries took the challenge to liberalize their economies. Quarter of a century later, to our knowledge, there is little or no consensus about the empirical relationship between trade liberalization events and food availability/security. The purpose of this paper is to examine empirically the effect of trade liberalization on food availability in selected developing countries. An econometric analysis of panel data seems to suggest that trade liberalization exerted a negative short run effect on food availability in the sample countries. The overall (or net) results, however, fail to support the view that the medium to long run effect of trade liberalization on food availability is favorable. The results of the study provide further evidence on the ambiguity of the impacts of trade, and trade liberalization in particular, on food security.

description: Colloids that interact via a short-range attraction serve as the primary building blocks for a broad range of self-assembled materials. However, one of the well-known drawbacks to this strategy is that these building blocks rapidly and readily condense into a metastable colloidal gel. Using computer simulations, we illustrate how the addition of a small fraction of purely repulsive self-propelled colloids, a technique referred to as active doping, can prevent the formation of this metastable gel state and drive the system toward its thermodynamically favored crystalline target structure. The simplicity and robust nature of this strategy offers a systematic and generic pathway to improving the self-assembly of a large number of complex colloidal structures. We discuss in detail the process by which this feat is accomplished and provide quantitative metrics for exploiting it to modulate self-assembly. We provide evidence for the generic nature of this approach by demonstrating that it remains robust under a number of different anisotropic short-ranged pair interactions in both two and three dimensions. In addition, we report on a novel microphase in mixtures of passive and active colloids. For a broad range of self-propelling velocities, it is possible to stabilize a suspension of fairly monodisperse finite-size crystallites. Surprisingly, this microphase is also insensitive to the underlying pair interaction between building blocks. The active stabilization of these moderately-sized monodisperse clusters is quite remarkable and should be of great utility in the design of hierarchical self-assembly strategies. This work further bolsters the notion that active forces can play a pivotal role in directing colloidal self-assembly.

description: Predicting the spatial configuration of gas molecules in nanopores of shale formations is crucial for fluid flow forecasting and hydrocarbon reserves estimation. The key challenge in these tight formations is that the majority of the pore sizes are less than 50 nm. At this scale, the fluid properties are affected by nanoconfinement effects due to the increased fluid-solid interactions. For instance, gas adsorption to the pore walls could account for up to 85% of the total hydrocarbon volume in a tight reservoir. Although there are analytical solutions that describe this phenomenon for simple geometries, they are not suitable for describing realistic pores, where surface roughness and geometric anisotropy play important roles. To describe these, molecular dynamics (MD) simulations are used since they consider fluid-solid and fluid-fluid interactions at the molecular level. However, MD simulations are computationally expensive, and are not able to simulate scales larger than a few connected nanopores. We present a method for building and training physics-based deep learning surrogate models to carry out fast and accurate predictions of molecular configurations of gas inside nanopores. Since training deep learning models requires extensive databases that are computationally expensive to create, we employ active learning (AL). AL reduces the overhead of creating comprehensive sets of high-fidelity data by determining where the model uncertainty is greatest, and running simulations on the fly to minimize it. The proposed workflow enables nanoconfinement effects to be rigorously considered at the mesoscale where complex connected sets of nanopores control key applications such as hydrocarbon recovery and CO2 sequestration.

description: Excitations of impurity complexes in semiconductors can not only provide a route to fill the terahertz gap in optical technologies, but can also connect local quantum bits to scale up solid-state quantum-computing devices. However, taking into account both the interactions among electrons/holes, and the host band structures, is challenging. Here we combine first-principles band-structure calculations with quantum-chemistry methodology to evaluate the ground and excited states of a pair of phosphorous donors in silicon within s single framework. We use a broken-symmetry Hartree-Fock approach, followed by a time-dependent Hartree-Fock method to compute the excited states. Our Hamiltonian for each valley includes an anisotropic kinetic energy term, which splits the 2p_0 and 2p_+- transitions of isolated donors by ~4 meV, in good agreement with experiments. Our single-valley calculations show the optical response is a strong function of the optical polarisation, and suggest the use of valley polarisation to control optics and reduce oscillations in exchange interactions. When taking into account all valleys, including valley-orbital interactions, we find a gap opens between the 1s to 2p transition and low-energy charge-transfer states within 1s manifolds (which become optically allowed because of inter-donor interactions). In contrast to the single-valley case, we find charge-transfer excited states also in the triplet sector, thanks to the valley degrees of freedom. These states have a qualitatively correct energy as compared with the previous experiments; additionally, we predict new excitations below 20 meV that have not been analysed previously. A statistical average of nearest-neighbour pairs at different separations suggests that THz radiation could be used to excite pairs spin-selectively. Our approach can readily be extended to other donors and to other semiconducting hosts.

description: We consider solutions to the linear wave equation on a (maximally extended) Schwarzschild spacetime, assuming only that the solution decays suitably at spatial infinity on a complete Cauchy hypersurface. (In particular, we allow the support of the solution to contain the bifurcate event horizon.) We prove uniform decay bounds for the solution in the exterior regions, including the uniform bound Cv_+^{-1}, where v_+ denotes max{v,1} and v denotes Eddington-Finkelstein advanced time. We also prove uniform decay bounds for the flux of energy through the event horizon and null infinity. The estimates near the event horizon exploit an integral energy identity normalized to local observers. This estimate can be thought to quantify the celebrated red-shift effect. The results in particular give an independent proof of the classical uniform boundedness theorem of Kay and Wald, without recourse to the discrete isometries of spacetime.

description: The optimal cost of a three-qubit Fredkin gate is 5 two-qubit entangling gates, and the overhead climbs to 8 when restricted to controlled-not (CNOT) gates. By harnessing higher-dimensional Hilbert spaces, we reduce the cost of a three-qubit Fredkin gate from 8 CNOTs to 5 nearest-neighbor CNOTs. We also present construction of an n-control-qubit Fredkin gate with 2n+3 CNOTs and 2n single-qudit operations. Finally, we design deterministic and nondeterministic three-qubit Fredkin gates in photonic architectures. The cost of a nondeterministic three-qubit Fredkin gate is further reduced to 4 nearest-neighbor CNOTs, and the success of such a gate is heralded by a single-photon detector. Our insights bridge the gap between the theoretical lower bound and the current best result for the n-qubit quantum computation.

Learning outcomes approach in British Columbia’s colleges and university colleges
Creators: name: Sunell, Susanne
Publisher: name: University of British Columbia
Year: 2009

description: This study investigated the suitability of adopting a learning outcomes approach as a strategy for educational reform in British Columbia's colleges and university colleges. It focused on the views of institutional and department administrators during the initial implementation phase through a questionnaire (n=313), interviews (n=58) and the analysis of provincial documents. Study participants had varied reactions to a learning outcomes approach ranging from strong support to overt resistance. Proponents viewed it as a philosophical shift from teaching to learning involving themes such as transparency, integrated curricula, holistic curricula, and a learner-centered focus. However, many viewed learning outcomes as being similar to their current approach. Opponents viewed the approach as being too simplistic, too limiting and unsupported by evidence. Its central position in the reform agenda was questioned. The barriers to its implementation included competing priorities, lack of resources, faculty workload, organizational culture, pedagogical issues, concerns about the vocationalization of postsecondary education and its perceived relationship to the provincial government's accountability movement. Approximately one third of respondents who had made changes identified them as valuable to their programs and courses. However, respondents from academic areas had less involvement, less interest in integration and perceived it as less valuable than respondents from applied areas. The value of the approach resonated at the theoretical level, but often disappeared in the practice context particularly at the course level. It was viewed as being particularly valuable in applied areas, but was most often described as a refinement. The learning outcomes approach was too abstract to provide a vision for reform. While there have been changes in specific courses and programs, the policy did not have a provincial impact from a pedagogical or accountability perspective. The term has been integrated into many organizational documents, but it is unclear if these changes translated into more relevant learning experiences or more valid assessment approaches. The discussions generated about best practices have been the greatest impact of the policy. It forced faculty members to challenge and defend their educational practices. This may be the ultimate legacy of the learning outcomes policy in British Columbia.
Nuclear spirals in galaxies: gas response to asymmetric potential. I. Linear theory
Creators: name: Maciejewski, Witold
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Nuclear spirals can provide a wealth of information about the nuclear potential in disc galaxies. They are unlikely to form in nuclei with solid-body rotation, yet they are present in a majority of galactic centres. Their morphology varies depending on whether a central massive black hole (MBH) is present or absent in the galaxy. In this paper I consider predictions of the linear theory for waves induced in gas by asymmetric gravitational potential, which are applicable to the nuclear spirals observed in galaxies. Generation and propagation of waves is governed by dynamical resonances, and inclusion of a MBH can move or even create resonances, greatly altering the extent and shape of the nuclear spiral. I will use predictions of the linear theory presented here as a guideline when interpreting hydrodynamical models in the second paper of this series. I also comment on modifications that self-gravity in gas imposes on the induced waves.

description: Additional file 1: Supplementary Fig. 1. IHC validation by comparison of antibodies. The panels demonstrate a confirmation of all prostein stainings obtained by MSVA-460R by the independent antibody EPR4795(2). Using MSVA-460R, a granular, predominantly perinuclear staining was seen in epithelial cells of the prostate (A), stomach surface (B), respiratory epithelium (C), the adenohypophysis (D), and of pancreatic islets (E), as well as in some monocytic cells of the spleen (F) while staining was lacking in the first trimenon placenta (G) and the testis (H). Using clone EPR4795(2), identical cell types stained in the prostate (I), stomach (K), respiratory epithelium (L), adenohypophysis (M), pancreatic islets (N), and in the spleen (O). A cytoplasmic staining in the placenta (P) and in testicular cells of the spermatogenesis (Q) was only seen by EPR4795(2) and therefore considered an antibody-specific cross-reactivity of EPR4795(2). The images A-H and I-Q are from consecutive tissue sections.

description: The Ca II infrared triplet around 8540 A is a good candidate for observing chromospheric magnetism. We show results from combining a radiation hydrodynamic simulation with a Stokes synthesis code. The simulation shows interesting time-varying behavior of the Stokes V profiles as waves propagate through the lines' formation regions. Disappearing and reappearing lobes in the Stokes V profiles as well as profile asymmetries are closely related to the atmospheric velocity gradients.

description: A simple measure is proposed that estimates the volume of trade distortion caused by the agricultural policies of trading countries. The index, called a TDS (Trade Distorted by support), would be useful for trade analysts to compare the trade impact of agricultural support policies across countries and commodities. The TDS index can be calculated largely from existing information on agricultural support. A TDS index might also be used to assess damages in trade dispute settlement cases.
Partial Reform of World Rice Trade: Implications for the U.S. Rice Sector

subject: simulation model

description: This paper analyzes the consequences for the United States of a partial reform of world rice trade. It is argued that likely trade reform would occur in the japonica rice producing countries of Japan, South Korea, Taiwan, and the European Community. Multilateral rice trade liberalization would have strong effects for medium grain rice in the United States. The strength of these effects might not be felt for a couple of years after the liberalization has begun because of minimal Japanese imports in the first couple of years of liberalization. U.S. rice millers will likely benefit more than producers. California producers would be the major beneficiaries of more open world rice markets.

description: The pace of political-economic change in former East Bloc nations of Europe defies accurate prediction. Some events such as more price-directed markets are predictable enough but integration of former East Bloc countries into the European Community remains a matter of speculation. Analysis indicates that the economics of agriculture favors acceptance by the European Community of members of the European Free Trade Association before former members of the. East Bloc. Analysis also indicates the considerable agricultural production potential of Central and East Europe will be unleased first by market-directed economies and later by integration with the EC -- if the latter occurs. US consumers gain more than producers lose so the economic welfare of Americans is raised modestly.

description: Within the $t$--$J$ model Hamiltonian we present a RVB mean field theory directly in terms of dopant particles. We apply this theory to $\mathrm{Na}_{x}\mathrm{CoO_{2}}\cdot y% \mathrm{H_{2}0}$ and show that the resulting phase diagram $T_c$ versus doping is in qualitative agreement with the experimental results.

description: In the fabrication of micro electrode arrays (MEAs) photolithographic methods common in semiconductor manufacturing are needed due to feature sizes down to a few microns. Due to wide availability, reasonable device costs and suitable performance, optical UV-lithography utilizing chrome masks is the most common patterning method [1]. The drawback of this method is, however, the need for a new set of relatively expensive masks for each new MEA design. Depending on the layers and fabrication processes used, several photolithographic steps and thus several masks might be needed for one MEA design, rising the mask costs per one MEA design to thousands of euro. Manufacturing and shipping of new masks cause also delays to MEA development process. To cut mask costs and time needed for prototyping or even commercial production of new MEA designs, we suggest a concept where the modified part of the design is patterned using maskless direct writing method. The concept and an economical self built digital exposure device [2] for direct writing are introduced in the following chapters.
A size of ~1 AU for the radio source Sgr A* at the centre of the Milky Way

description: Although it is widely accepted that most galaxies have supermassive black holes (SMBHs) at their centers^{1-3}, concrete proof has proved elusive. Sagittarius A* (Sgr A*)^4, an extremely compact radio source at the center of our Galaxy, is the best candidate for proof^{5-7}, because it is the closest. Previous Very Long Baseline Interferometry (VLBI) observations (at 7mm) have detected that Sgr A* is ~2 astronomical unit (AU) in size^8, but this is still larger than the "shadow" (a remarkably dim inner region encircled by a bright ring) arising from general relativistic effects near the event horizon^9. Moreover, the measured size is wavelength dependent^{10}. Here we report a radio image of Sgr A* at a wavelength of 3.5mm, demonstrating that its size is \~1 AU. When combined with the lower limit on its mass^{11}, the lower limit on the mass density is 6.5x10^{21} Msun pc^{-3}, which provides the most stringent evidence to date that Sgr A* is an SMBH. The power-law relationship between wavelength and intrinsic size (The size is proportional to wavelength^{1.09}), explicitly rules out explanations other than those emission models with stratified structure, which predict a smaller emitting region observed at a shorter radio wavelength.

Obscured AGN and the X-ray, Optical and Far-Infrared Number Counts of AGN in the GOODS Fields

description: The deep X-ray, optical, and far-infrared fields that constitute GOODS are sensitive to obscured AGN (N_H>10^{22} cm^{-2}) at the quasar epoch (z~2-3), as well as to unobscured AGN as distant as z~7. Luminous X-ray emission is a sign of accretion onto a supermassive black hole and thus reveals all but the most heavily obscured AGN. We combine X-ray luminosity functions with appropriate spectral energy distributions for AGN to model the X-ray, optical and far-infrared flux distributions of the X-ray sources in the GOODS fields. A simple model based on the unified paradigm for AGN, with ~3 times as many obscured AGN as unobscured, successfully reproduces the z-band flux distributions measured in the deep HST ACS observations on the GOODS North and South fields. This model is also consistent with the observed spectroscopic and photometric redshift distributions once selection effects are considered. The previously reported discrepancy between observed spectroscopic redshift distributions and the predictions of population synthesis models for the X-ray background can be explained by bias against the most heavily obscured AGN generated both by X-ray observations and the identification of sources via optical spectroscopy. We predict the AGN number counts for Spitzer MIPS 24 um and IRAC 3.6-8 um observations in the GOODS fields, which will verify whether most AGN in the early Universe are obscured in the optical. Such AGN should be very bright far-infrared sources and include some obscured AGN missed even by X-ray observations.
