description: The Formation of Catastrophically Cooling Outflows in Star-forming Regions via Non-equilibrium Radiative Cooling Multiwavelength surveys of star-forming regions suggest the presence of catastrophically cooling outflows, also sometimes accompanied by warm outflows and hot bubbles. Mechanical feedback from super star clusters in starburst regions can produce cooling galactic-scale outflows, but starburst-driven outflows predicted by the adiabatic fluid models cannot lead to very strong cooling seen in several star-forming galaxies such as M82 and NGC 2366. We therefore simulate starburst-driven outflows using time-dependent non-equilibrium radiative cooling functions of the MAIHEM non-equilibrium package in the framework of the hydrodynamics code FLASH in order to determine the existence domains of strongly radiative cooling, so called catastrophic cooling, in the parameter space of the gas metallicity, outflow mass-loading, outflow kinetic heating efficiency, and ambient density. Although the gas metallicity has a major role in cooling, radiative cooling is significantly enhanced by increasing mass-loading and decreasing kinetic heating efficiency. Our simulations indicate hot bubbles may appear even with both the adiabatic and substantially radiative cooling outflows. Our results demonstrate the significance of non-equilibrium radiative cooling for star-forming regions, where coolants could be responsible for the build-up of cold molecular hydrogen (H2) clumps that can trigger the formation of new stars as gravitational collapse occurs once the H2 clump’s mass exceeds the Jeans critical mass.

description: Active galactic nuclei (AGN) produce vast amounts of high energy radiation deep in their central engines. X-rays either escape the AGN or are absorbed and re-emitted mostly as IR. By studying the dispersion in the ratio of observed mid-IR luminosity to observed 2-10keV X-ray luminosity (R_{ir/x}) in AGN we can investigate the reprocessing material (possibly a torus or donut of dust) in the AGN central engine, independent of model assumptions. We studied the ratio of observed mid-IR and 2-10keV X-ray luminosities in a heterogeneous sample of 245 AGN from the literature. We found that when we removed AGN with prominent jets, ~90% of Type I AGN lay within a very tight dispersion in luminosity ratio (1

description: Automorphisms of the canonical core UHF-subalgebra F_n of the Cuntz algebra O_n do not necessarily extend to automorphisms of O_n. Simple examples are discussed within the family of infinite tensor products of (inner) automorphisms of the matrix algebras M_n. In that case, necessary and sufficient conditions for the extension property are presented. It is also addressed the problem of extending to O_n the automorphisms of the diagonal D_n, which is a regular MASA with Cantor spectrum. In particular, it is shown the existence of product-type automorphisms of D_n that are not extensible to (possibly proper) endomorphisms of O_n.

description: Local dissipation scales are a manifestation of the intermittent small-scale nature of turbulence. We report the first experimental evaluation of the distribution of local dissipation scales in turbulent pipe flows for a range of Reynolds numbers, 2.4x10^4<=Re_D<=7.0x10^4. Our measurements at the nearly isotropic pipe centerline and within the anisotropic logarithmic layer show excellent agreement with distributions that were previously calculated from numerical simulations of homogeneous isotropic box turbulence and with those predicted by theory. The reported results suggest a universality of the smallest-scale fluctuations around the classical Kolmogorov dissipation length.

Gender-based violence and COVID-19 : how the pandemic has shifted GBV policies, and implications for non-governmental organisations and non-profits
Creators: name: Botterill, Lindsay
Publisher: name: University of British Columbia
Year: 2024

description: In this research I ask: How effectively have Canadian federal and provincial policies shifted to meet the needs of Non-Governmental Organisations and non-profits in British Columbia that serve those who have experienced Intimate Partner Violence (IPV), following the COVID-19 pandemic? Secondly, what can be done to improve the situation? Little research currently exists on this subject, as Canada continues to recover from the implications of the pandemic. To best answer these questions, I examined Gender-Based Violence policies over the past several decades created by the federal government and provincial government of British Columbia. In particular, I employed a policy trajectory approach to consider whether policy adaptations were implemented to meet the increased needs of non-profits and NGOs as a result of challenges brought upon by COVID-19. In tandem with policy trajectory analysis, I utilised an intersectional feminist framework rooted in the scholarship of those like Angela Davis, Kimberlé Crenshaw, and Patricia Hill Collins, as well as supporting literature from Indigenous activists who wrote the MMIWG report, work of disability scholars, LGBTQ2S+ researchers, and others. The inclusion of these authors demonstrates the disproportionate experiences of partner violence, as well as the additional barriers members of marginalised communities face when seeking services. Importantly, I drew upon this work to highlight the ways in which government policies have failed to address gaps in support systems for survivors. Ultimately, the findings of my research have underlined the ways in which policies implemented during the pandemic were largely reactive. Instead, recommendations produced here suggest that governments must: (1) proactively engage with non-profits, survivors and other stakeholders to not only stop partner violence, but proactively prevent it; (2) governments at all levels must acknowledge their role within systems of oppression and work collaboratively with impacted communities to address barriers; and (3) government officials find ways to shift leadership to those on the frontlines, as well as survivors, to guide policy creation and consultation moving forward.

description: A mixed quantum mechanical and Monte Carlo method for calculating Auger spectra from nanoclusters is presented. The approach, based on a cluster method, consists of two steps. Ab initio quantum mechanical calculations are first performed to obtain accurate energy and probability distributions of the generated Auger electrons. In a second step, using the calculated line shape as electron source, the Monte Carlo method is used to simulate the effect of inelastic losses on the original Auger line shape. The resulting spectrum can be directly compared to 'as-acquired' experimental spectra, thus avoiding background subtraction or deconvolution procedures. As a case study, the O K-LL spectrum from solid SiO2 is considered. Spectra computed before or after the electron has traveled through the solid, i.e., unaffected or affected by extrinsic energy losses, are compared to the pertinent experimental spectra measured within our group. Both transition energies and relative intensities are well reproduced.

Complete resolution of sister chromatid intertwines requires the Polo-like kinase Cdc5 and the phosphatase Cdc14 in budding yeast
Creators: name: MASSARI, LUCIA FRANCESCA
Publisher: name: Universit� degli Studi di Milano
Year: 2018

description: During mitosis the newly replicated genetic material, organized in sister chromatids, is equally subdivided into the daughter cells through a fine-regulated process called chromosome segregation. Sister chromatids are held together and identified as sisters by cohesin. At the metaphase-to-anaphase transition, when all chromatids are correctly attached to the spindle, cohesin is cleaved and chromosome segregation initiates. Beside cohesin, all linkages between sister chromatids need to be removed to allow for their complete separation. Additional linkages include DNA linkages (or sister chromatid intertwines, SCIs), such as recombination intermediates and DNA catenanes. In Saccharomyces cerevisiae a mutant that lacks the activities of the Polo-like kinase Cdc5 and the phosphatase Cdc14, two major mitotic regulators, has been identified that proved to be particularly suitable for studying SCIs that persist in mitosis. The cdc5 cdc14 double mutant arrests with short and stable mitotic spindles and unseparated nuclei, despite having cleaved cohesin. In addition to having a spindle elongation defect, these cells are also impaired in the resolution of cohesin-independent linkages between chromatids. We found that these linkages mostly consist of DNA catenanes, that persist in cdc5 cdc14 cells at their terminal arrest and that are sufficient to counteract spindle elongation. Our results suggest that Cdc5 is required for their resolution. This finding, together with the knowledge that Cdc5 promotes Cdc14 activation and that both proteins are essential for spindle elongation and mitotic exit, allows us to speculate that they coordinate different aspects of chromosome segregation to guarantee genome integrity throughout mitosis.

description: A sample of edge-on spiral galaxies aimed at a study of the main structural and photometric parameters of edge-on galaxies both of early and late types is presented. The data were taken from the 2MASS in the J, H and K_s filters. The sample consists of 175 galaxies in the K_s-filter, 169 galaxies in the H-filter and 165 galaxies in the J-filter. We present bulge and disc decompositions of each galaxy image. All galaxies have been modelled with a Sersic bulge and exponential disc with the BUDDA v2.1 package. The main conclusions of our general statistical analysis of the sample are: (1) The distribution of the apparent bulge axis ratio q_b for the subsample with n < 2 can be attributed to triaxial, nearly prolate bulges that are seen from different projections, while n > 2 bulges seem to be oblate spheroids with moderate flattening. (2) For the sample galaxies, the effective radius of the bulge r_{e,b}, the disc scalelength h and the disc scaleheight z_0 are well correlated. However, there is a clear trend for the ratio r_{e,b}/h to increase with n. (3) There is a hint that the fundamental planes of discs, which links only disc parameters and the maximum rotational velocity of gas, are different for galaxies with different bulges. (4) The investigation of the Photometric Plane of sample bulges shows that the plane is not flat and has a prominent curvature towards small values of n. For bulges this fact was not noticed earlier. (5) The clear relation between the flattening of stellar discs h/z_0 and the relative mass of a spherical component, including a dark halo, is confirmed not for bulgeless galaxies but for galaxies with massive bulges.

description: One of the most challenging problems in understanding the structural phase transformations in Pu is to determine the energetically favored, continuous atomic pathways from one crystal symmetry to another. This problem involves enumerating candidate pathways and studying their energetics to garner insight into instabilities and energy barriers. The purpose of this work is to investigate the energetics of two transformation pathways for the delta to alpha' transformation in Pu that were recently proposed [Lookman et al., Phys. Rev. Lett. 100:145504, 2008] on the basis of symmetry. These pathways require the presence of either an intermediate hexagonal closed-packed (hcp) structure or a simple hexagonal (sh) structure. A subgroup of the parent fcc and the intermediate hexagonal structure, which has trigonal symmetry, facilitates the transformation to the intermediate hcp or sh structure. Phonons then break the translational symmetry from the intermediate hcp or sh structure to the final monoclinic symmetry of the alpha' structure. We perform simulations using the modified embedded atom method (MEAM) for Pu to investigate these candidate pathways. Our main conclusion is that the path via hcp is energetically favored and the volume change for both pathways essentially occurs in the second step of the transformation, i.e. from the intermediate sh or hcp to the monoclinic structure. Our work also highlights the deficiency of the current state-of-the-art MEAM potential in capturing the anisotropy associated with the lower symmetry monoclinic structure.

HIGH RESOLUTION MASS SPECTROMETRY STRATEGIES FOR THE IDENTIFICATION OF SMALL AND LARGE BIOACTIVE MOLECULES.
Creators: name: ALTOMARE, ALESSANDRA ANNA
Publisher: name: Universit� degli Studi di Milano
Year: 2015

description: Abstract The aim of the present thesis was to set-up and to apply an analytical approach based on proteomics for the identification of bioactive macromolecules contained in two complex bioactive matrices, bovine colostrum and panax ginseng, that could be exploited for nutraceutical and pharmaceutical applications. The approach starts with proteome characterization, followed by bioinformatics analysis aimed not only at addressing the biological activity of the identified proteins and at establishing protein-protein interaction, but also at predicting the bioactivity of the digested peptides arising from gastro-intestinal digestion. The knowledge generated by such an approach permits not only the production of a safe and high quality/standardized bioactive matrix, but also the set-up of suitable analytical protocols aimed at analyzing qualitatively and quantitatively the bioactive proteins. The goal was reached through an integrated analytical strategy based on a proteomic and bioinformatics approach and by applying innovative techniques for sample preparation, including affinity chromatography and the combinatorial peptide library technology (CPLL or PM, ProteoMiner), aimed at reducing the dynamic range of protein concentrations. In the first part of the work, the proteomic approach was used to generate an exhaustive protein data bank of bovine colostrum, including the minor protein components. By using a bioinformatics approach, a cluster of bioactive proteins effective for treating wound healing was identified. An integrated analytical strategy was then set-up for the quality control of the bioactive protein components of bovine colostrum (part II). Asian ginseng (Panax ginseng C. A. Meyer), one of the most highly regarded of herbal medicines in the Orient, was selected as the second matrix to be studied; a comprehensive proteomic analysis was carried out together with a bioinformatics approach for protein/peptide bioactive constituents (part III). Overall, this work contributes not only to mapping the Bovine Colostrum and Panax Ginseng proteomes, but also to setting-up a suitable analytical platform aimed at achieving a high standardization and an in-depth quality profiling of bovine colostrum in the manufacture of food supplements. The identification of proteins characterized by innovative functions through proteomic and bioinformatic approaches also permits the exploration of novel biological functions of Bovine Colostrum and Panax Ginseng. This innovative approach can be applied to the further exploration of various natural sources of bioactive macromolecules, which are claimed to have health benefits.

description: As database technology is applied to more and more application areas, user queries on a database become more and more complex. Existing query optimization techniques were not developed for dealing with complex queries and may suffer from some serious problem such as intolerably long optimization time and poor optimizing results. To tackle this challenge, we introduce a new technique to improve the quality of complex query optimization in this paper. The key idea is to exploit the common subqueries that often appear in a complex query and reuse the optimization work done for each common subquery. An algorithm to identify common subqueries efficiently and generate a high-quality execution plan for a given complex query is proposed. The complexity of the algorithm is analyzed. Experiments demonstrate that this proposed polynomial-time technique is quite promising in optimizing complex queries for a database management system.

description: The mucus layer is a hydrogel network that covers mucosal surfaces of the human body. Mucus has important protective properties that are related to its unique rheological properties, which are based on mucins being the main glycoprotein constituents. Mucin macromolecules entangle with one another and form a physical network that is instrumental for many important defense functions. Mucus derived from various human or animal sources is poorly defined and thus not suitable for many application purposes. Herein, a synthetic route is fabricated to afford a library of compositionally defined mucus-inspired hydrogels (MIHs). MIHs are synthesized by thiol oxidation to render disulfide bonds between the crosslinker ethoxylated trimethylolpropane tri(3-mercaptopropionate) (THIOCURE ETTMP 1300) and the linear precursors, dithiolated linear polyglycerol (LPG(SH)2) or polyethylene glycol (PEG(SH)2) of different molecular weights. The mixing ratio of linear polymers versus crosslinker and the length of the linear polymer are varied, thus delivering a library of compositionally defined mucin-inspired constructs. Their viscoelastic properties are determined by frequency sweeps at 25 and 37 °C and compared to the corresponding behavior of native human mucus. Here, MIHs composed of a 10:1 ratio of LPG(SH)2 and ETTMP 1300 are proved to be the best comparable to human airway mucus rheology.

Navigating sustainability, affordability, and livability in Vancouver's Broadway Plan
Creators: name: Belotti, Giulia
Publisher: name: University of British Columbia
Year: 2024

description: Within urban environments, land use emerges as a vital component in climate mitigation strategies. As cities seek solutions to reduce GHG emissions, transit-oriented development (TOD) is increasingly recognized as a promising approach, given that transportation is a major emitter in urban areas. However, densification and TOD are subjects of intense debate and controversy. This research sheds light on urban residents’ perceptions of transit-oriented development, focusing on the Broadway Plan, a transit-oriented initiative recently approved by the City of Vancouver, as a case study. Through non-participant observation of public hearings and semi-structured interviews, common patterns in the perceptions of residents, community groups, and experts towards transit-oriented development were identified. The NIMBY (Not In My Backyard), YIMBY (Yes In My Backyard), and PHIMBY (Public Housing In My Backyard) archetypes were employed to better grasp such complexity, allowing for the identification of trends and tendencies in resident’s arguments. The study reveals that people’s lived experiences significantly shape their attitudes toward development, influencing their vision of an ideal city and the policy direction they believe local governments should take. Moreover, the research highlights the exclusive nature of public hearings as an engagement process, suggesting the need for reshaping such methods to foster more inclusive participation. The findings underscore the disparity in access to local institutions faced by marginalized populations, limiting their influence on shaping their cities. Recognizing the importance of equity, this research advocates adopting an equity lens in engagement and transit-oriented development to achieve both climate and housing goals, while ensuring that no current or future resident is left behind.
The Milky Way is not special:accreted stars also inhabit the Lithium Spite Plateau
Creators: name: Simpson, Jeffrey
Publisher: name: Zenodo
Year: 2021

description: The ESA Gaia astrometric mission has enabled the remarkable discovery that a large fraction of the stars within a few kiloparsecs of the Sun appear to be debris from a single in-falling system, the so-called Gaia-Sausage-Enceladus. One exciting feature of this result is that it gives astronomers for the first time a large sample of easily observable, unevolved stars that formed in an extra-Galactic environment, which can be compared to stars that formed within our Milky Way. In this talk I will discuss using these stars to investigate the “Spite Plateau” – the near-constant lithium abundance observed in metal-poor dwarf stars across a wide range of metallicities (-3 < [Fe/H] < -1). In particular our aim was to test whether the stars that formed in Gaia-Sausage-Enceladus show a different Spite Plateau to Milky Way stars that inhabit the disk and halo. Individual galaxies could have different Spite Plateaus – e.g., the interstellar medium could be more depleted in lithium in a lower galactic mass system due to it having a smaller reservoir of gas. We find that the Gaia-Sausage-Enceladus stars show the same lithium abundance as other likely accreted stars and in situ Milky Way stars, strongly suggesting that the “lithium problem” is not a consequence of the formation environment. This result fits within the growing consensus that the Spite Plateau, and more generally the “cosmological lithium problem” – the observed discrepancy between the amount of lithium in warm, metal-poor dwarf stars in our Galaxy, and the amount of lithium predicted to have been produced by Big Bang Nucleosynthesis – is the result of lithium depletion processes within stars.

The Southern Stellar Stream Spectroscopic Survey

Year: 2021

description: The Southern Stellar Stream Spectroscopic Survey (S5) is an ongoing international collaboration to map the newly discovered stellar streams of the Milky Way halo with the fiber-fed AAOmega spectrograph on the Anglo-Australian Telescope (AAT). S5 is the first systematic program pursuing a complete census of known streams in the Southern Sky, providing a uniquely powerful sample for understanding the building blocks of the Milky Way's stellar halo, the progenitors and formation of stellar streams, the mass and shape of the Milky Way's halo, and ultimately the nature of dark matter. The survey started in Summer 2018 and has mapped ~20 streams with over 50 nights on AAT, collecting around ~ 100k stellar spectra. Some of the key results include the detection that the ATLAS stream and Aliqa Uma streams are likely one stream that has been perturbed by Sagittarius, detection of the fastest hypervelocity star S5-HVS1, the detection of the lowest metallicity stellar stream and the characterization of chemical abundances of individual streams. In this talk I will review some of the recent results from the survey, including the recent data release.

description: In this paper we consider nonnegatively curved finite dimensional Alexandrov spaces with a non-collapsing condition, i.e., such that unit balls have volumes uniformly bounded from below away from zero. We study the relation between the isoperimetric profile, the existence of isoperimetric sets, and the asymptotic structure at infinity of such spaces. In this setting, we prove that the following conditions are equivalent: the space has linear volume growth; it is Gromov--Hausdorff asymptotic to one cylinder at infinity; it has uniformly bounded isoperimetric profile; the entire space is a tubular neighborhood of either a line or a ray. Moreover, on a space satisfying any of the previous conditions, we prove existence of isoperimetric sets for sufficiently large volumes, and we characterize the geometric rigidity at the level of the isoperimetric profile. Specializing our study to the $2$-dimensional case, we prove that unit balls have always volumes uniformly bounded from below away from zero, and we prove existence of isoperimetric sets for every volume, characterizing also their topology when the space has no boundary. The proofs exploit a variational approach, and in particular apply to Riemannian manifolds with nonnegative sectional curvature and to Euclidean convex bodies. Up to the authors' knowledge, most of the results are new even in these smooth cases.

description: In many scientific settings data can be naturally partitioned into variable groupings called views. Common examples include environmental (1st view) and genetic information (2nd view) in ecological applications, chemical (1st view) and biological (2nd view) data in drug discovery. Multi-view data also occur in text analysis and proteomics applications where one view consists of a graph with observations as the vertices and a weighted measure of pairwise similarity between observations as the edges. Further, in several of these applications the observations can be partitioned into two sets, one where the response is observed (labeled) and the other where the response is not (unlabeled). The problem for simultaneously addressing viewed data and incorporating unlabeled observations in training is referred to as multi-view transductive learning. In this work we introduce and study a comprehensive generalized fixed point additive modeling framework for multi-view transductive learning, where any view is represented by a linear smoother. The problem of view selection is discussed using a generalized Akaike Information Criterion, which provides an approach for testing the contribution of each view. An efficient implementation is provided for fitting these models with both backfitting and local-scoring type algorithms adjusted to semi-supervised graph-based learning. The proposed technique is assessed on both synthetic and real data sets and is shown to be competitive to state-of-the-art co-training and graph-based techniques.

description: Silicon carbide MOSFETs have increasingly been recognized as advantageous compared to conventional silicon IGBTs; however, they face significant challenges due to a high defect density in the raw material. To optimize semiconductor efficiency, it is critical to minimize both conduction and switching losses. Conduction losses are influenced by on-state resistance and device breakdown voltage, while switching losses are dependent on switching speed, which is constrained by turn-off voltage overshoot and system stray inductance. Therefore, the reduction of stray inductance is paramount for decreasing both types of losses. This work presents a comprehensive analysis of the current state of the art, outlining essential device characteristics and limitations. It identifies the distribution of stray inductance in the DC-link and power module as significant constraints. While DC-snubber circuits are discussed as a potential solution, their effectiveness decreases at higher currents due to increased damping losses. An active controlled snubber is introduced, and its operational principles in conjunction with a half-bridge configuration are described. This setup facilitates a substantial reduction in stray inductance during MOSFET and diode turn-off, resulting in negligible losses during turn-on. The analytical description of the operational mechanism reveals opportunities for zero-current switching of the auxiliary switch. The derived model is validated through empirical measurements and is employed to predict behavior in subsequent switching events. Comparative analysis with a similar DC-snubber configuration indicates that the active snubber exhibits alternating yet stable voltage behavior, with a maximum snubber voltage much lower as with a conventional DC-snubber. Three-phase inverters designed for switching frequencies of 10 kHz and 30 kHz demonstrate a potential increase in output power of 35% for non-optimized semiconductors and 59% for optimized MOSFETs. Furthermore, the introduced configuration is utilized to actively drive a small LC-filter, evaluating its applicability under constraints on maximum voltage slope. A dependency between snubber voltage and the timing of filter pulses has been identified. In comparison to a state-of-the-art IGBT setup with similar output power, a reduction in switching losses by a factor of 20 was observed, accompanied by a concurrently lower voltage slope. However, the time constants of the snubber circuit limit the minimization of the LC-filter.

description: The thesis describes the work of Isabelle Eberhardt, a travel writer who explores Algeria and Tunisia between 1897 and 1904. The establishment of the original edition of her texts presents several problems considering that quite a number of publishers modified them. The analysis of the editions that are available today and the consultation of manuscripts retained in the Archives nationales d'outre-mer in Aix-en-Provence, allowed to obtain some helpful clarification on this subject, even if the situation remains delicate. Isabelle Eberhardt travels to the islamic Maghreb with the intention of living in Algeria for good, in the desire to construct her new identity, write publishable texts, learn more about local traditions. The diversity of projects means that there is a personal involvement as well a literary and scientific intention. The research method used by our writer during her journeys has been investigated and summerized by the alternation of engagement and estrangement. Eberhardt's poetics is equally clear and it is based on the valorization of the lieu's vitality as well as on the definition of an existential and living space. The texts are the product of a formation process knowledge-based and with a literary purpose. They have been analyzed with a critical and interpretative approach. Isabelle Eberhardt's experience and the values that it promotes make possible a rapprochement with the studies exploring connections between literature and geography.

description: Context: Knowledge about the coronal magnetic field is important to the understanding the structure of the solar corona. We compute the field in the higher layers of the solar atmosphere from the measured photospheric field under the assumption that the corona is force-free. Aims: Here we develop a method for nonlinear force-free coronal magnetic field medelling and preprocessing of photospheric vector magnetograms in spherical geometry using the optimization procedure. Methods: We describe a newly developed code for the extrapolation of nonlinear force-free coronal magnetic fields in spherical coordinates over a restricted area of the Sun. The program uses measured vector magnetograms on the solar photosphere as input and solves the force-free equations in the solar corona. We develop a preprocessing procedure in spherical geometry to drive the observed non-force-free data towards suitable boundary conditions for a force-free extrapolation. Results: We test the code with the help of a semi-analytic solution and assess the quality of our reconstruction qualitatively by magnetic field line plots and quantitatively with a number of comparison metrics for different boundary conditions. The reconstructed fields from the lower boundary data with the weighting function are in good agreement with the original reference fields. We added artificial noise to the boundary conditions and tested the code with and without preprocessing. The preprocessing recovered all main structures of the magnetogram and removed small-scale noise. The main test was to extrapolate from the noisy photospheric vector magnetogram with and without preprocessing. The preprocessing was found to significantly improve the agreement between the extrapolated and the exact field.

description: We give a causal inference scheme using quantum observations alone for a case with both temporal and spatial correlations: a bipartite quantum system with measurements at two times. The protocol determines compatibility with 5 causal structures distinguished by the direction of causal influence and whether there are initial correlations. We derive and exploit a closed-form expression for the space-time pseudo-density matrix (PDM) for many times and qubits. This PDM can be determined by light-touch coarse-grained measurements alone. We prove that if there is no signalling between two subsystems, the reduced state of the PDM cannot have negativity, regardless of initial spatial correlations. In addition, the protocol exploits the time asymmetry of the PDM to determine the temporal order. The protocol succeeds for a state with coherence undergoing a fully decohering channel. Thus coherence in the channel is not necessary for the quantum advantage of causal inference from observations alone.

Essays on economic development, violence and infrastructure

description: The purpose of this thesis is to develop a deeper understanding of the relationship between economic development, infrastructure development - with a particular focus on roads and electricity - and potentially mitigating factors such as insurrectional violence and corrup- tion. My approach is empirical. For Chapters 1 and 2, I digitalised archival road maps and collected satellite night light data to produce objective measures of development programs output. In Chapter 3, we use household electricity consumption data of rural Rwandan communities. Leveraging this data, I shed light on the effectiveness of development pro- grams, public or private, local or regional, using various econometric approaches, ranging from Instrumental Variable to OLS. In the first chapter, I explore the link between infrastructure development programs and violence. I examine empirically the direct and indirect effects of physical road building and road spending programs on violence in Iraq from 2003 to 2016 using both an instrumental variable (IV) and a first-difference and approach. In the second chapter, I try to answer the following questions: does corruption affect economic development? If so, to what extent and why? I delve into the Iraqi setting and leverage the data collected for Chapter 1 to measure corruption. First, I build a novel in- dex of corruption per district. Then I proceed to test the relationship between this index of leakage and health and literacy outcomes. Using an event-study approach, I compare the differential impact of development programs on illiteracy and child malnutrition in cor- rupt and non-corrupt Iraqi districts and find that corruption alters development programs’ efficiency. In the third and last chapter, we study electricity consumption behaviours of rural com- munities connected to a distributed nanogrid system in Rwanda. We use a novel household level electricity consumption dataset of over 4,000 users in close to 80 communities in Rwanda collected by a solar nanogrid system provider to identify a sharing behaviour.
