description: Este artículo analiza algunas de las sentencias proferidas por la sección tercera del Consejo de Estado, en donde se han ordenado medidas de reparación simbólica a favor de las víctimas de graves violaciones de derechos humanos. Adicionalmente, se examina la iniciativa pedagógica “Sueños de Paz”, que es un proyecto creado en el año 2017 por los docentes de ciencias sociales del Colegio Luis Eduardo Mora Osejo, que busca aportar en la reparación simbólica de las víctimas del conflicto armado interno. Esta iniciativa, resalta la literatura como uno de los mecanismos que contribuye a la reparación simbólica de las víctimas, ya que permite la exteriorización de los sentimientos experimentados por quienes se vieron afectados por hechos victimizantes. Asimismo, favorece la no repetición, puesto que constituye una herramienta de sensibilización frente al dolor que producen las ejecuciones extrajudiciales.
description: This article analyzes some of the judgments issued by the third section of the Council of State, where symbolic reparation measures have been ordered in favor of the victims of serious human rights violations. In addition, the pedagogical initiative "Sueños de Paz" is examined, which is a project created in 2017 by the social science teachers of the Luis Eduardo Mora Osejo School, which seeks to contribute to the symbolic reparation of the victims of the internal armed conflict. This initiative, highlights literature as one of the mechanisms that contributes to the symbolic reparation of the victims, since it allows the externalization of the feelings experienced by those who were affected by victimizing acts. Likewise, it favors non-repetition, since it constitutes a tool for raising awareness of the pain produced by extrajudicial executions.

description: Extending nanostructures into the third dimension has become a major research avenue in modern magnetism, superconductivity and spintronics, because of geometry-, curvature- and topology-induced phenomena. Here, we introduce Co-Fe nanovolcanoes-nanodisks overlaid by nanorings-as purpose-engineered 3D architectures for nanomagnonics, fabricated by focused electron beam induced deposition. We use both perpendicular spin-wave resonance measurements and micromagnetic simulations to demonstrate that the rings encircling the volcano craters harbor the highest-frequency eigenmodes, while the lower-frequency eigenmodes are concentrated within the volcano crater, due to the non-uniformity of the internal magnetic field. By varying the crater diameter, we demonstrate the deliberate tuning of higher-frequency eigenmodes without affecting the lowest-frequency mode. Thereby, the extension of 2D nanodisks into the third dimension allows one to engineer their lowest eigenfrequency by using 3D nanovolcanoes with 30% smaller footprints. The presented nanovolcanoes can be viewed as multi-mode microwave resonators and 3D building blocks for nanomagnonics.

description: Constitution-making is a ubiquitous but poorly understood phe- nomenon. There is much speculation but relatively little evidence about the impact of different design processes on constitutional outcomes. Much of the debate reduces to the question of who is involved in the process and when. We consider two central issues in this regard. The first is the problem of institutional self-dealing, or whether governmen- tal organs that have something to gain from the constitutional outcome should be involved in the process. The second has to do with the mer- its of public involvement in the process. Both of these concerns have clear normative implications and both are amenable to straightforward social scientific analysis. This article surveys the relevant research on constitution-making, describes the conceptual issues involved in un- derstanding constitution-making, reviews the various claims regarding variation in constitution-making processes, and presents a set of base- line empirical results from a new set of data on the content and process of constitution-making.
A new approach to mass balance modeling: applications to igneous petrology
Creators: name: Ke, Peiwan
Publisher: name: University of British Columbia
Year: 2008

description: An overdetermined linear system of equations is proposed to investigate mass balance relationships in igneous systems. A chi square (x²) minimization technique is used to solve the set of linear equations. The x² technique is superior to R² techniques because it considers the analytical errors on measurement data. Singular Value Decomposition (SVD) is used to search for the x² optimal solution. The attributes of the x² technique are discussed. The x² minimization fitting technique, combined with SVD methods allows the confidence regions to be calculated and expressed by a geometric shape centered on the x² optimal solution. The geometric shape varies with the dimension of the linear system: one-dimensional cases yield a line fragment; two-dimensional cases yield an ellipse and the three dimensions require an ellipsoid. The size of the confidence regions is determined by the confidence limits and is related to the coefficient matrix of the linear problem. Model with smaller confidence regions are considered to be better than models associated with larger confidence regions where the same confidence limit is used. Therefore, the confidence region can be used to select the model that best explains chemical differentiation in igneous system. Synthetic data sets have been analyzed using the new program MASSBAL.0 which solves the mass balance problems using the principles of the x² technique and SVD. The x² technique presents a solution closer to the true one than does the traditional residual minimization fitting (R² technique). It overcomes the deficiencies that the R² technique has and appears to be a more robust and sensitive fitting technique. The x² technique has been applied to the apparent clinopyroxene paradox formed in lavas from Diamond Craters, Oregon. Three models are proposed to explain the chemical difference: a three phase model (01+P1+Px), a two phase model (O1+Pl) and a one phase model (01). The x² mass balance modeling results show that the three phase model (O1+Pl+Px) has the smallest minimum x² value and the most compact confidence region; thus it is preferred and clinopyroxene did participate in the fractionation process. The x² technique has also been applied to study the assimilation problem in Paricutin volcano and the fractionation problem in PLA group of Mount Meager volcanic complex. The mass balance calculations show that assimilation has play a major role in Paricutin volcano and about 15% xenolith has contaminated the magma. In PLA fractionation processes, plagioclase and amphibole are shown to have caused the chemical difference between lavas, although other phenocrysts ( biotite and pyroxene ) did not participate.

Stratigraphy, maturation and source rock potential of cretaceous strata in the Chilcotin-Nechako region of British Columbia
Creators: name: Hunt, Julie A.
Publisher: name: University of British Columbia
Year: 2008

description: The Chilcotin-Nechako region lies within the Intermontane Belt of British Columbia on the western edge of Stikinia and includes the Tyaughton Basin. Exposed within the region are Early Albian to Cenomanian sediments of the Skeena, Taylor Creek, Jackass Mountain and Battlement Ridge groups plus unnamed sediments of similar age and lithology. These sediments were deposited in one large, initially marine, basin (Nazko Basin) and are separated from older sediments by a major hiatus (Barremian to Aptian in the south and Berriasian to Valanginian in the north). Marine conditions persisted in the northern Chilcotin-Nechako region until at least Cenomanian time, and until the Maastrichtian in the central Chilcotin-Nechako region. In southern Chilcotin-Nechako region, marine conditions ceased in mid Albian time with the deposition of the Silverquick formation. Latest Albian - Cenomanian time marks the transition from a dominantly sedimentary to volcanic province. Volcanism was widespread throughout the Chilcotin-Nechako region until at least the Santonian (Kasalka and upper Kingsvale groups, Powell Creek formation, unnamed volcanics and possibly the Brian Boni Formation). In Central Chilcotin-Nechako region volcanism was succeeded by marine sedimentation in the Santonian which continued until Maastrichtian time, indicating marine conditions persisted on the mainland of British Columbia well beyond the previously documented Albian limit. Sediments in the Nazko Basin were sourced from the Omineca Belt and the Cache Creek Terrane to the east and the Insular Terrane to the west. In the southern region detritus was also provided by the Bridge River Terrane. New data from this study indicate mid to Late Cretaceous sediments within the Chilcotin-Nechako region are zeolite facies. This low grade of metamorphism isprobably due to comparatively low heat flow in the Chilcotin-Nechako region. When compared to equivalent strata exposed to the north, sediments within the Nazko Basin have markedly lower maturation values even though they have experienced the same amount of burial. Sediments with zeolite grade metamorphism have the potential to lie within the oil window and thus may contain significant hydrocarbon reserves. However, Rock-Eval pyrolysis and TOC analyses of outcrop and well samples indicate the overall hydrocarbon potential of the Chilcotin-Nechako region is low.

description: We find a family of exact solutions of Einstein equations describing the field of a static axisymmetric thin disk living in six-dimensional space-time. In particular, we study the disks constructed (by cutting out the central part of the spacetime) from the conventional Schwarzschild and Chazy-Curzon solutions with simple extensions in the extra 2 dimensions. The disks are interpreted in terms of two counter-rotating streams of particles on free circular orbits. Two extra parameters -- the constants of motion resulting from projections of the particle-velocities' extra components -- are constrained by the requirement that the orbits within the disk be stable. The requirement is met just in cases when the radial profile of the disk orbital speed fits the rotation curves of many spiral galaxies. It thus turns out that the effective modification of the gravity law by extra dimensions could explain the observed flatness of these curves equally well as the usually given dark-matter interpretation. In the second part of the paper we show that the inclusion of extra dimensions also leads to better fits of the gravitational-lensing data for galaxy clusters, without changing results obtained in solar-system scales. Finally, we discuss whether the effect of extra dimensions could also be translated as following from the occurrence of extra matter ("Kaluza-Klein particles"). A comment on possible properties of such particles and a chance to detect them at LHC is given in the appendix.

description: A number of finite algorithms for constructing representation theoretic data from group multiplications in a finite group G have recently been shown to be related to amplitudes for combinatoric topological strings (G-CTST) based on Dijkgraaf-Witten theory of flat G-bundles on surfaces. We extend this result to projective representations of G using twisted Dijkgraaf-Witten theory. New algorithms for characters are described, based on handle creation operators and minimal multiplicative generating subspaces for the centers of group algebras and twisted group algebras. Such minimal generating subspaces are of interest in connection with information theoretic aspects of the AdS/CFT correspondence. For the untwisted case, we describe the integrality properties of certain character sums and character power sums which follow from these constructive G-CTST algorithms. These integer sums appear as residues of singularities in G-CTST generating functions. S-duality of the combinatoric topological strings motivates the definition of an inverse handle creation operator in the centers of group algebras and twisted group algebras.

description: Intraspecific variation in snake venom composition has been the subject of many studies, revealing the differences in venom proteomes according to age, diet, sex, and geographic region. Previous research on M. lebetinus venom mainly focused on protein purification, proteomic characterization, and biological activities. Although venom proteomes of its subspecies from different geographical areas were compared, it is a widespread species and there is limited knowledge regarding the individual venom variation of M. lebetinus in the same area. In this study, individual variation in M. lebetinus obtusa venom was investigated in terms of protein profiles, protease, phospholipase A2, ʟ-amino acid oxidase, hyaluronidase and phosphodiesterase, and hemolytic activities based on nine individuals collected in the province of Şanlıurfa (southeastern Türkiye). HPLC analysis indicated more striking differences compared to SDS-PAGE. Phosphodiesterase activity varied most between the individuals, followed by hyaluronidase and phospholipase A2. Hemolytic activity did not show significant alteration based on the blood agar method. The results of this initial study revealed that M. lebetinus venom shows variation between the individuals inhabiting the same habitat, which should be taken into account in the development of antivenoms and the clinical assessment of the bite cases.

description: The metal insulator transition of nano-scaled $VO_2$ devices is drastically different from the smooth transport curves generally reported. The temperature driven transition occurs through a series of resistance jumps ranging over 2 decades in amplitude, indicating that the transition is caused by avalanches. We find a power law distribution of the jump amplitudes, demonstrating an inherent property of the $VO_2$ films. We report a surprising relation between jump amplitude and device size. A percolation model captures the general transport behavior, but cannot account for the statistical behavior.

Steerable wavelet analysis of CMB structures alignment

description: This paper reviews the application of a novel methodology for analysing the isotropy of the universe by probing the alignment of local structures in the CMB. The strength of the proposed methodology relies on the steerable wavelet filtering of the CMB signal. One the one hand, the filter steerability renders the computation of the local orientation of the CMB features affordable in terms of computation time. On the other hand, the scale-space nature of the wavelet filtering allows to explore the alignment of the local structures at different scales, probing possible different phenomena. We present the WMAP first-year data analysis recently performed by the same authors (Wiaux et al.), where an extremely significant anisotropy was found. In particular, a preferred plane was detected, having a normal direction with a northern end position close to the northern end of the CMB dipole axis. In addition, a most preferred direction was found in that plane, with a northern end direction very close to the north ecliptic pole. This result synthesised for the first time previously reported anomalies identified in the direction of the dipole and the ecliptic poles axes. In a forthcoming paper (Vielva et al.), we have extended our analysis to the study of individual frequency maps finding first indications for discarding foregrounds as the origin of the anomaly. We have also tested that the preferred orientations are defined by structures homogeneously distributed in the sky, rather than from localised regions. We have also analysed the WMAP 3-year data, finding the same anomaly pattern, although at a slightly lower significance level.

description: We have designed honeycomb lattices for microwave photons with a frequency imbalance between the two sites in the unit cell. This imbalance is the equivalent of a mass term that breaks the lattice inversion symmetry. At the interface between two lattices with opposite imbalance, we observe topological valley edge states. By imaging the spatial dependence of the modes along the interface, we obtain their dispersion relation that we compare to the predictions of an ab initio tight-binding model describing our microwave photonic lattices.
Constraining Dark Energy by Combining Cluster Counts and Shear-Shear Correlations in a Weak Lensing Survey

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: We study the potential of a large future weak-lensing survey to constrain dark energy properties by using both the number counts of detected galaxy clusters (sensitive primarily to density fluctuations on small scales) and tomographic shear-shear correlations (restricted to large scales). We use the Fisher matrix formalism, assume a flat universe and parameterize the equation of state of dark energy by w(a)=w_0+w_a(1-a), to forecast the expected statistical errors from either observable, and from their combination. We show that the covariance between these two observables is small, and argue that therefore they can be regarded as independent constraints. We find that when the number counts and the shear-shear correlations (on angular scales l < 1000) are combined, an LSST (Large Synoptic Survey Telescope)-like survey can yield statistical errors on (Omega_DE, w_0, w_a) as tight as (0.003, 0.03, 0.1). These values are a factor of 2-25 better than using either observable alone. The results are also about a factor of two better than those from combining number counts of galaxy clusters and their power spectrum.

The worth of data in predicting aquitard continuity in hydrogeolgical design
Creators: name: James, Bruce Rennie
Publisher: name: University of British Columbia
Year: 2008

description: A Bayesian decision framework is developed for addressing data worth questions for hydrogeological design in heterogeneous geological environments. This framework is developed specifically for aiding hydrogeologists, dealing with groundwater contamination, in the design of exploration programs searching for aquitard discontinuities. It can be used to evaluate, and compare, the cost effectiveness of (a) patterns of precise point measurements (e.g. boreholes), which are often expensive, and (b) areal geophysical surveys which are imprecise, but usually less expensive. The framework consists of two basic modules: a geostatistical indicator algorithm for simulating aquitard heterogeneity and a numerical model for simulating contaminant transport. Bayesian decision analysis ties these two modules together. The Bayesian nature of the framework also provides a methodology for combining a conceptual understanding of the local geology with quantitative information. Indicator geostatistics allows the handling of hydrogeological parameters which behave in space as non-Gaussian random variables. The estimated worth of a measurement was found to be particularly sensitive to economic parameters. It was less sensitive to hydrogeological and geostatistical parameters. The framework was applied in a retrospective fashion to the design of a remediation program for soil contaminated by radioactive waste disposal at the Savannah River Site, in South Carolina. The cost effectiveness of different patterns of point measurements was studied. This study included determining the number and spacing of the most cost effective pattern. Contour maps were produced of the net worth of a single, point measurement. These contour maps can be used to design sequential sampling programs involving single or multiple measurements. Good potential was also shown for determining the cost effectiveness of an a real geophysical survey. The net worth of patterns of precise, point measurements was compared to that of an imprecise, a real seismic survey. These results indicate that the framework can be very valuable in determining if additional exploration is cost effective and in designing efficient exploration programs. Results also show that ignoring a conceptual understanding of geology can lead to erroneous data worth analysis. The framework could be modified to handle other data worth questions in hydrogeology or other disciplines, such as mining, or petroleum reservoir engineering.
The role of BMPR2 and SOX17 deficiency in endothelial dysfunction: implications for pulmonary arterial hypertension
Creators: name: Mahomed, Abdul Sattar Fakee
Publisher: name: Imperial College London
Year: 2022

description: Background: Pulmonary arterial hypertension (PAH) is characterized by endothelial cell dysfunction and obliterative lung vascular remodelling, culminating in right-sided heart failure and death. Bone morphogenetic protein receptor type 2 (BMPR2) is firmly established as a PAH-risk gene, whereby deficiency of functional BMPR2 is known to disrupt endothelial homeostasis. In addition, mutations in the SRY-box transcription factor 17 (SOX17) gene have recently been associated with development of the disease. However, given its only recent implication in PAH, the understanding of SOX17 deficiency in endothelial dysfunction is in its infancy. Blood flow-induced shear stress is well documented as a regulator of endothelial function and the transcriptome. Emerging, albeit limited evidence, suggests that the dysfunctional endothelium in PAH, including due to loss of BMPR2, exhibit defective shear stress responsiveness. Therefore, this project sought to investigate the effects BMPR2 and SOX17 deficiency on the regulation of shear-induced gene expression (selected PAH/endothelial function markers). Approach and results: siRNA-mediated BMPR2-silenced (siBMPR2) human pulmonary artery endothelial cells (HPAECs) or that of non-targeting control treated cells (siControl) were exposed to PAH-relevant shear stress profiles; laminar or bidirectional oscillatory flow (1Hz) at 1.5, 15 or 90 dyne/cm2 or cultured under static conditions. Under laminar flow (15 dyne/cm2) BMPR2 knockdown led to decreased shear-induced (relative to static siControl) production of several genes including, cyclooxygenase 2 (COX2), interleukin (IL)6 and IL8, compared with siControl cells. Notably these observations selectively occurred under shear magnitudes of 15 dyne/cm2 (and not 1.5 or 90 dyne/cm2) and almost exclusively under laminar flow. SOX17 knockdown in HPAECs (static) resulted in the identification of marked overexpression of angiostatic chemokines, C-X-C motif chemokine ligand 10 (CXCL10) and CXCL11, driven by excessive nuclear factor kappa B (NF-κB) p65 activity, compared with siControl HPAECs. In addition, SOX17 silencing upregulated mRNA of a diverse array of markers, most of which have previously been described in the pathobiology of PAH, for example, EDN1 (endothelin-1). Monolayer integrity of SOX17-silenced HPAECs was also reduced, as determined by real-time impedance measurements. Conclusion: The application of specific shear stress profiles disrupts pulmonary endothelial gene regulation under conditions of reduced BMPR2. SOX17 loss in HPAECs induces mediators and characteristics of endothelial dysfunction previously established in PAH, in particular the upregulation of angiostatic factors CXCL10 and CXCL11.
Development of new fluoride and HF transfer reactions
Creators: name: Mulryan, Daniel
Publisher: name: Imperial College London

description: The element fluorine is becoming increasingly pervasive in modern life. It is commonly incorporated into pharmaceutical and agrochemical compounds, inert materials, polymers, refrigerant gases, aerosols and electrolytes amongst other applications. But the current fluorine industry has three major problems. These are: the dwindling supply of fluoride containing mineral resources; the safety and practicality concerns of handling toxic fluorinating or hydrofluorinating agents; and the environmental impacts of many ‘single-use’ fluorinated products. The development of fluorine (F2), fluoride (F-) and hydrogen fluoride (HF) transfer technologies can alleviate all three of these key issues through the formation of a fluorine cycle. Within this thesis, three new catalytic systems for the transfer of fluoride or hydrogen fluoride between organic substrates are presented. The systems cover the fluoride metathesis of perfluoroarenes with carbonyl derivatives; the hydrofluorination of alkynes through the reaction of perfluoroarenes with protic nucleophiles and the shuttling of hydrogen fluoride between fluoroalkanes and alkynes. For each system a scope of substrates is presented along with mechanistic insights through kinetic analysis and computational modelling (DFT). This work represents a proof of principle that will hopefully aid the future development of fluorine recycling technologies that are necessary for the future sustainability of the fluorine industry.

description: We use density-functional theory with the local-density approximation to study the structural and ferroelectric properties of SrTiO$_3$ under misfit strains. Both the antiferrodistortive (AFD) and ferroelectric (FE) instabilities are considered. The rotation of the oxygen octahedra and the movement of the atoms are fully relaxed within the constraint of a fixed in-plane lattice constant. We find a rich misfit strain-induced phase transition sequence and is obtained only when the AFD distortion is taken into account. We also find that compressive misfit strains induce ferroelectricity in the tetragonal low temperature phase only whilst tensile strains induce ferroelectricity in the orthorhombic phases only. The calculated FE polarization for both the tetragonal and orthorhombic phases increases monotonically with the magnitude of the strains. The AFD rotation angle of the oxygen octahedra in the tetragonal phase increases dramatically as the misfit strain goes from the tensile to compressive strain region whilst it decreases slightly in the orthorhombic (FO4) phase. This reveals why the polarization in the epitaxially strained SrTiO$_3$ would be larger when the tensile strain is applied, since the AFD distortion is found to reduce the FE instability and even to completely suppress it in the small strain region. Finally, our analysis of the average polar distortion and the charge density distribution suggests that both the Ti-O and Sr-O layers contribute significantly to the FE polarization.

description: We generalize the experimental success criterion for quantum teleportation/memory in continuous-variable quantum systems to be suitable for non-unit-gain condition by considering attenuation/amplification of the coherent-state amplitude. The new criterion can be used for a non-ideal quantum memory and long distance quantum communication as well as quantum devices with amplification process. It is also shown that the framework to measure the average fidelity is capable of detecting all Gaussian channels in quantum domain.

Structure, evolution, and petroleum potential of the Queen Charlotte Basin
Creators: name: Lyatsky, Henry
Publisher: name: University of British Columbia
Year: 2008

description: This study focuses on the structure and evolution of the Tertiary Queen Charlotte sedimentary basin and its petroleum potential. The study is based on integrated geological basin analysis, which involves compiling all relevant geological, geophysical, and geochemical data; interpreting them using a multidisciplinary approach; and creating a petroleum-exploration model for the basin. The Queen Charlotte Basin lies offshore, and its geologic structure was interpreted from gravity, magnetic, and seismic data. Potential-field trend patterns are similar to physiographic lineaments. Regional faults are the Kitkatla, Principe Laredo/Banks Island, and Sandspit. Their crosscutting relationships, lack of strike-slip displacements, and presence of through going Oligocene dikes, all preclude substantial strike-slip movements in the basin during the Neogene. The origin of the basin by large extension and strike-slip faulting is ruled out; a model based on block tectonics is offered instead. The similarity of orthogonal, Tertiary fault networks within the basin with Mesozoic or older networks on its flanks, suggests the inheritance of the main structural characteristics of the basin from pre-Tertiary time. Themosaic of fault-bounded blocks was formed no later than the Late Jurassic; since then, block faulting and structural inversion have occurred repeatedly. Tertiary extension was too small to obliterate the older fault pattern. Large plutons lie beneath eastern Queen Charlotte Sound, on trend with the Neogene Anahim volcanic belt on the mainland. These features reflect the passage of the region over a mantle hot spot in the Miocene, which may have also caused the renewal of tectonic activity. Igneous heating and hydrothermal-fluid circulation occurred locally, whereas burial-related conductive heating was regional in scale. Petroleum potential is associated chiefly with Mesozoic rocks beneath Queen Charlotte Sound. Source rocks occur in the Upper Triassic-Lower Jurassic interval, and reservoirs in the Cretaceous units. Tertiary rocks form a regional seal. The Hecate Strait area lacks thick Mesozoic rocks, but the Queen Charlotte Sound area contains Mesozoic source and reservoir rocks, overlain by a Tertiary seal. The Cretaceous stratigraphic interval, which may contain large block structures, should be the primary target for future petroleum activity.

Optimal conversion of Bose condensed atoms into molecules via a Feshbach resonance

description: In many experiments involving conversion of quantum degenerate atomic gases into molecular dimers via a Feshbach resonance, an external magnetic field is linearly swept from above the resonance to below resonance. In the adiabatic limit, the fraction of atoms converted into molecules is independent of the functional form of the sweep and is predicted to be 100%. However, for non-adiabatic sweeps through resonance, Landau-Zener theory predicts that a linear sweep will result in a negligible production of molecules. Here we employ a genetic algorithm to determine the functional time dependence of the magnetic field that produces the maximum number of molecules for sweep times that are comparable to the period of resonant atom-molecule oscillations, $2πΩ_{Rabi}^{-1}$. The optimal sweep through resonance indicates that more than 95% of the atoms can be converted into molecules for sweep times as short as $2πΩ_{Rabi}^{-1}$ while the linear sweep results in a conversion of only a few percent. We also find that the qualitative form of the optimal sweep is independent of the strength of the two-body interactions between atoms and molecules and the width of the resonance.
