description: First principles studies were performed in order to find out the possibility of inducing half-metallicity in Heusler Compound CoFeMnSb, by means of alloying it with 3d-transition metal elements. Proper alloying element is selected through the calculations of formation energies. These calculations were tested with different concentrations of alloying elements at different atomic sites. Among the selected transition metal elements Sc and Ti are proposed to be excellent alloying elements particularly at Mn site. By using these alloying elements complete half metallic behaviour is obtained in CoFeMn0.25Sc0.75Sb, CoFeMn0.75Ti0.25Sb, CoFeMn0.625Ti0.375Sb, CoFeMn0.50Ti0.50Sb, CoFeMn0.25Ti0.75Sb and CoFeTiSb alloys. Shifting of Co-Fe d-states towards lower energy region leads to zero density of states at Fermi level for the spin minority channel. Alloying effects on the electronic structure and magnetization are discussed in details. Thermodynamical stability of these new alloys are major part of this study. The Curie temperatures of CoFeMn0.25Sc0.75Sb and CoFeMn0.75Ti0.25Sb were found to be 324.5 K and 682 K; respectively, showing good candidature for spintronics applications. For understanding the bonding nature of constituent atom of CoFeMnSb, crystal orbital Hamiltonian populations have been analysed.
Skid road rehabilitation techniques for restoring productivity in the B.C. interior

Year: 2009

description: Ground based harvesting, or ground skidding, is still an acceptable harvesting method on gentler slopes and on less sensitive soils. Skid road rehabilitation is a relatively new treatment; for excavated and bladed trails, rehabilitation became a requirement on many sites under the 1995 Forest Practices Code. It will be required on all sites by June 15, 1998. In order to evaluate how trees have been growing on skidroad rehab, we have sampled sites in the east and west Kootenay that are as old as 1984. These sites are growing trees, and with improved techniques, applied to the least sensitive sites, we don't see any problems restoring soil productivity. More sensitive sites still need more study at this time. Successful skid road rehabilitation starts with a good understanding of the site condition and management constraints. Proper construction is key. Removal of woody debris and outsloping decompaction will ensure drainage restoration, along with regularly spaced, open waterbars. Replacing soil horizons in reverse order with minimal mixing will help restore topsoil, which is then protected and augmented with woody debris and slash loading similar to the surrounding area.

description: Islam and Competing Nationalisms: The Kurds and the Turks in the late Ottoman Era is a work, which traces how religion was intimately intertwined with nationalism during the crucial period of the late nineteenth century in the Modern Middle East. In this approach, I call into question the extent to which the principle of secularism and ethnicity serve as the only foundations of the modern nation state. Within the context of the late Ottoman Empire, my research foregrounds the differences between interpretations of Islam at the center and the myriad understandings of Islam adopted by those on the margins. I demonstrate how diverse Muslim communities (Arabs, Kurds and Turks) have linked their interpretations of 'authentic' religion to claims of 'ethnic superiority' during the process of nation building. I contend that this tension between the normative State interpretation of Islam and alternative visions was critical in shaping modern nationalism in the Middle East. This is significant for establishing how nationalism can in turn affect the range of religious interpretations. My work thus provides a new historically grounded theoretical foundation for recent debates on nationalism that have emerged in recent decades. My dissertation is based on a close examination of British archival records, Ottoman state records, Ottoman journals and other primary sources in Arabic, Kurdish (both Kurmanci and Sorani dialects), Persian and modern Turkish -- most of which I obtained during my yearlong field research as a Fulbright scholar.

description: Designing future farming systems which are resilient in an increasingly volatile and uncertain environment can be challenging. Scenario planning to inform farm systems design can help address this challenge. In the first phase of this wider scenario planning project, three distinct future world scenarios were developed. In this second phase of the scenario planning project, dairy farm systems for these future scenarios were developed over two workshops: a farmer workshop followed by an industry workshop where participants used mental models to conceptualise the future farm systems for each scenario. In general, the farm systems were most diverse under the consumer-driven Consumer is King (CK) scenario, and least diverse under the Government Dictates (GD) scenario (political chaos with trade dictated by governments). There was considerable overlap between farm systems under the CK and the highly regulatory Regulation Rules (RR) scenarios, but very little farm system overlap between the GD scenario and the other two scenarios. These future farm systems descriptions will play an important role in informing the quantitative modelling phase of this project. The approaches used to identify and describe the conceptual future farm systems were considered to be effective.

Capacity Bounds and Degrees of Freedom for MIMO Antennas Constrained by Q-Factor

description: The optimal spectral efficiency and number of independent channels for MIMO antennas in isotropic multipath channels are investigated when bandwidth requirements are placed on the antenna. By posing the problem as a convex optimization problem restricted by the port Q-factor a semi-analytical expression is formed for its solution. The antennas are simulated by method of moments and the solution is formulated both for structures fed by discrete ports, as well as for design regions characterized by an equivalent current. It is shown that the solution is solely dependent on the eigenvalues of the so-called energy modes of the antenna. The magnitude of these eigenvalues is analyzed for a linear dipole array as well as a plate with embedded antenna regions. The energy modes are also compared to the characteristic modes to validate characteristic modes as a design strategy for MIMO antennas. The antenna performance is illustrated through spectral efficiency over the Q-factor, a quantity that is connected to the capacity. It is proposed that the number of energy modes below a given Q-factor can be used to estimate the degrees of freedom for that Q-factor.

Hydrological ensembles to improve monthly flow predictions in the Magdalena – Cauca macrobasin, Colombia

Publisher: name: figshare
Year: 2019

description: Multi-model and multi-analysis procedures have shown that predictions made using ensembles that take into account different model structures and different meteorological forcing datasets are more skillful and reliable. To understand more about forcing data, model structures and interactions between them, the Bayesian Model Averaging (BMA) has been applied in hydrology mainly to forecast combinations among several hydrological models. In this regard, BMA was implemented in the Magdalena Cauca Macro Basin (MCMB) in Colombia (257,000 km2) using different ensemble structures (e.g., number and type of members) determining the weight of each member in each ensemble and quantifying their predictive ability using the Kling-Gupta Efficiency (KGE) deterministic metric.
The BMA was applied in the MCMB on a monthly timescale, obtaining the weights per member in ensembles developed to represent observed discharges in 88 streamflow gauges selected in the MCMB during the period 1981-2011. For each gauge station the best ensembles were selected from a set of possible combinations (e.g., 65,519 cases per gauge station) that comprised the hydrological and land surface models: VIC, wflow-hbv MESH and DWB, forced with three different meteorological datasets: quasi-observed, WFDEI and MSWEP; the EartH2Observe Tier-1 ensemble; and a set of global hydrological models (LISFLOOD, WaterGAP3 and HTESSEL) forced with MSWEP. Using BMA, the Gaussian mixture model was constructed by weighing the posterior distribution of individual hydrological models in the transformed space. The posterior probabilitymeasuring samples belonging to each specific hydrological model were treated as the weights.
The results of the best ensembles (TBE) for the 88 streamflow gauges selected in the MCMB showed increasesin the evaluated performance through KGE, in comparison with the best individual models (TBM). The 46.59 % of the stations reported KGE values during calibration higher than 0.81 using TBE, while in the case of TBM the percentage was lower (23.86 %). In the [0.61-0.80] range of the KGE, the results with the TBE reported a percentage of 29.22 % in comparison with a 42.05 % of TBM; similar results were also obtained in the ranges [0.41-0.60] and [0.21-0.40] of the KGE. A high diversity in the members of the ensembles was observed, yet for streamflow gauges nearby, and also from month to month, making it not clear a relationship between dry/wet season and members of the ensembles. Finally, the research evidenced that all the individual models and the ensembles analyzed have a poor performance in subbasins in the upper part of the Magdalena-Cauca watershed caused by flow regulation (not accounted for in any of the hydrological models analyzed) and also due to a poor estimation of the forcing precipitation field for both, gridded in-situ data and reanalysis, in a high relief terrain with lack of rainfall stations.

It is found that Se substitution effectively suppresses local distortion, that can be responsible for the increased carrier mobility together with a change in the electronic structure. The results suggest a possible way to control thermoelectric properties by tuning of the local crystal structure of these materials.

description: The water cycle is not only a generator of ecosystem services and a critical driver of Earth system change. Itis also a system subject to intense human interferences. Hydropower development is well known to modify theamount and variability of discharge in river streams around the world. Furthermore, there is growing evidence ofimpacts of reservoir impoundment and flow regulation on other hydroclimatic variables such as potential and actualevapotranspiration, convective energy and soil moisture. In this study, we performed a trend analysis of severalhydrological variables based on the Budyko framework in a 1,630 -km2 hydrological basin in Central Colombiaand two of its upstream subbasins. Our aim was to detect any possible hydroclimatic effect of the impoundmentof the Prado Reservoir within the Prado River hydrological basin. The hydroelectric project comprises a singlereservoir with an installed capacity of 1,1 x 106 m3 and a hydroelectric station that came into operation in 1973.We gathered monthly observed data for precipitation, temperature, radiation and runoff and used it to calculateinitially potential and actual evapotranspiration, the aridity index and the evaporative ratio during the period of1952-2014.We calculated change before and after the construction of the dam for all these variables, and a runningcoefficient of variation (CV) for both precipitation and runoff, and used statistical tests such as Pettitt andWilcoxonsignificance tests to identify changes in the trend series. We found that after the commissioning of the project,precipitation and runoff simultaneously decreased in all basins. The changes in variation and magnitude of the CVof runoff in the downstream station reflected the effects of regulation, effect not observed in the subbasins upstreamof the project. On the contrary, no effect of the reservoir was found on basin-scale evapotranspiration, as it has beenfound in other heavily regulated basins worldwide: after performing a separation technique on evapotranspirationchange, we found that the residual change in evapotranspiration not related to climate variability, and attributed toother factors, was negligible. This may be explained by the fact that the construction of only one reservoir withinthe hydrological basin may not be sufficient to evidence an effect on net evapotranspiration from flow regulationfrom the entire basin.

description: We study the existence and stability of spherical membranes in curved spacetimes. For Dirac membranes in the Schwarzschild--de Sitter background we find that there exists an equilibrium solution. By fine--tuning the dimensionless parameter $ΛM^2,$ the static membrane can be at any position outside the black hole event horizon, even at the stretched horizon, but the solution is unstable. We show that modes having $l=0$ (and for $ΛM^2<16/243$ also $l=1$) are responsible for the instability. We also find that spherical higher order membranes (membranes with extrinsic curvature corrections), contrary to what happens in flat Minkowski space, {\it do} have equilibrium solutions in a general curved background and, in particular, also in the ``plain'' Schwarzschild geometry (while Dirac membranes do not have equilibrium solutions there). These solutions, however, are also unstable. We shall discuss a way of by--passing these instability problems, and we also relate our results to the recent ideas of representing the black hole event horizon as a relativistic bosonic membrane.

description: Magnons, the quanta of spin waves, could be used to encode information in beyond-Moore computing applications, and magnonic device components, including logic gates, transistors, and units for non-Boolean computing, have already been developed. Magnonic directional couplers, which can function as circuit building blocks, have also been explored, but have been impractical because of their millimetre dimensions and multi-mode spectra. Here, we report a magnonic directional coupler based on yttrium iron garnet single-mode waveguides of 350 nm width. We use the amplitude of a spin-wave to encode information and to guide it to one of the two outputs of the coupler depending on the signal magnitude, frequency, and the applied magnetic field. Using micromagnetic simulations, we also propose an integrated magnonic half-adder that consists of two directional couplers and processes all information within the magnon domain with aJ energy consumption.

An overview of forest soil rehabilitation in the BC interior
Creators: name: Bulmer, Charles Ernest
Publisher: name: The University of British Columbia
Year: 2009

description: Interest in forest soil rehabilitation has increased during the 1990's as a result of requirements within the Forest Practices Code (FPC) and because of recent investments made by Forest Renewal BC. Our understanding of what is required to successfully restore productivity to degraded forest soils is limited because (1) few research projects were initiated during the past decade, (2) the range of site types studied so far is limited, and (3) many of the questions we ask about these projects require information on long-term tree growth response, which can only be collected as fast as the trees grow. This paper outlines the history of forest soil rehabilitation in BC, discusses growth- limiting conditions that need to be overcome for success, and describes three groups of techniques for restoring productivity, including tillage, topsoil replacement, and reforestation / revegetation. This paper summarizes the results of a problem analysis carried out during 1996 to examine existing information and assess the need for new information to improve the results and cost-effectiveness of soil rehabilitation efforts.

description: Strange modes have been found in the radial spectrum of many luminous stars, most recently in Cepheids and RR Lyrae. We show that there is nothing strange about these modes -- they must exist even in the adiabatic limit. With a change of variables and without approximation the adiabatic linear pulsation equation is reduced to a Schroedinger equation in which the radial coordinate is the local sound-traversal time. In this formulation, the narrow hydrogen partial ionization region is seen to act as a potential barrier, separating the star into two regions. Resonances between the two regions result in the strange modes, for which the ratio of interior to exterior amplitude is at a minimum. The relative location of the barrier changes with the stellar parameters, and this gives rise to avoided level-crossings along a sequence of models. 2 The appearance of strange modes and the associated level crossings are exhibited with an analytic toy-model with the potential barrier approximated by a delta function. This toy-model is readily extensible to nonadiabatic modes. Hydrodynamical calculations find that pure strange mode limit-cycles have extremely small photospheric velocities and luminosity variations in the milli-magnitude range. They are therefore expected to be difficult to observe.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: In the present work, a peculiar property of hash-based signatures allowing detection of their forgery event is explored. This property relies on the fact that a successful forgery of a hash-based signature most likely results in a collision with respect to the employed hash function, while the demonstration of this collision could serve as convincing evidence of the forgery. Here we prove that with properly adjusted parameters Lamport and Winternitz one-time signatures schemes could exhibit a forgery detection availability property. This property is of significant importance in the framework of crypto-agility paradigm since the considered forgery detection serves as an alarm that the employed cryptographic hash function becomes insecure to use and the corresponding scheme has to be replaced.

description: A method for computing the stress-energy tensor for the quantized, massless, spin 1/2 field in a general static spherically symmetric spacetime is presented. The field can be in a zero temperature state or a non-zero temperature thermal state. An expression for the full renormalized stress-energy tensor is derived. It consists of a sum of two tensors both of which are conserved. One tensor is written in terms of the modes of the quantized field and has zero trace. In most cases it must be computed numerically. The other tensor does not explicitly depend on the modes and has a trace equal to the trace anomaly. It can be used as an analytic approximation for the stress-energy tensor and is equivalent to other approximations that have been made for the stress-energy tensor of the massless spin 1/2 field in static spherically symmetric spacetimes.

description: Achieving sustainable development is regarded as a complex task and the SDGs have been designed to serve asguidelines for such goal. Since wetlands provide a wide range of environmental services to humanity, focusingon these ecosystems is crucial for achieving sustainable development in the countries in which the wetlands arelocated. The main objectives of this research were to: 1) Understand the SDG targets that should be prioritized inorder to achieve sustainable development in specific iconic wetlands around the world, 2) identify feed backs andsynergies across targets from a wetland perspective and 3) illustrate how wetland research can help achieve specificSDG targets. Data was collected on 36 wetlands across 5 continents and 17 countries by means of a questionnaireanswered by 40 wetland researchers of the Global Ecohydrological Network (GWEN– www.gwennetwork.se) anddesigned by a selected group of these researchers during a meeting held in April in Santa Marta, Colombia in April2018. Collected data were analyzed via both one-mode undirected and bipartite directed networks to answer thefirst two objectives.We found that of the 33 SDG targets that are wetland-related and that were previously selectedfor the study, four were considered a priority by at least 20 of the researchers: the Targets being 6.3 – “Improvewater quality”, 2.4 – “Ensure sustainable and resilient food production systems”, 8.4 – “Sustainable Consumptionand Production” and 12.2 – “Sustainable management of resources”. Furthermore, targets 12.2, 6.3 and 2.4resulted being the most influential by enabling and reinforcing the largest number of targets. However, target 2.4counteracted and constrained the largest amount of targets, but at a much smaller scale than when compared toits positive influence. The network analysis resulted in the identification of four wetland groups with distinctiveSDG-target bundles that researchers considered should be addressed as priority. We further illustrate for a particulariconic and degraded tropical wetland in Colombia, the Ciénaga Grande de Santa Marta, how hydrogeodesy (i.e.by Interferometric Synthetic Aperture Radar – InSAR) and ecohydrology studies can give valuable information tosome of these priority SDG targets in the region.

description: We study continuous groups of generalized Kerr-Schild transformations and the vector fields that generate them in any n-dimensional manifold with a Lorentzian metric. We prove that all these vector fields can be intrinsically characterized and that they constitute a Lie algebra if the null deformation direction is fixed. The properties of these Lie algebras are briefly analyzed and we show that they are generically finite-dimensional but that they may have infinite dimension in some relevant situations. The most general vector fields of the above type are explicitly constructed for the following cases: any two-dimensional metric, the general spherically symmetric metric and deformation direction, and the flat metric with parallel or cylindrical deformation directions.

description: We display a logarithmic divergence in the density matrix of a scalar field in the presence of an Einstein-Yang-Mills black hole in four dimensions. This divergence is related to a previously-found logarithmic divergence in the entropy of the scalar field, which cannot be absorbed into a renormalization of the Hawking-Bekenstein entropy of the black hole. As the latter decays, the logarithmic divergence induces a non-commutator term $\nd{δH}ρ$ in the quantum Liouville equation for the density matrix $ρ$ of the scalar field, leading to quantum decoherence. The order of magnitude of $\nd{δH}$ is $μ^2/M_P$, where $μ$ is the mass of the scalar particle.

description: We identify a set of dynamical maps of open quantum system, and refer to them as "$ ε$-Markovian" maps. It is constituted of maps which, in a higher dimensional system-environment Hilbert space, possibly violate Born approximation but only a "little". We characterize the "$ε$-nonmarkovianity" of a general dynamical map by the minimum distance of that map from the set of $ε$-Markovian maps. We analytically derive an inequality which gives a bound on the $ ε$-nonmarkovianity of the dynamical map, in terms of an entanglement-like resource generated between the system and its "immediate" environment. In the special case of a vanishing $ε$, this inequality gives a relation between the $ε$-nonmarkovianity of the reduced dynamical map on the system and the entanglement generated between the system and its immediate environment. We numerically investigate the behavior of the similar distant based measures of non-Markovianity for classes of amplitude damping and phase damping channels.

description: $GL_h(n) \times GL_h(m)$-covariant $h$-bosonic algebras are built by contracting the $GL_q(n) \times GL_q(m)$-covariant $q$-bosonic algebras considered by the present author some years ago. Their defining relations are written in terms of the corresponding $R_h$-matrices. Whenever $n=2$, and $m=1$ or 2, it is proved by using U_h(sl(2)) Clebsch-Gordan coefficients that they can also be expressed in terms of coupled commutators in a way entirely similar to the classical case. Some U_h(sl(2)) rank-1/2 irreducible tensor operators, recently contructed by Aizawa in terms of standard bosonic operators, are shown to provide a realization of the $h$-bosonic algebra corresponding to $n=2$ and $m=1$.

description: In this article we prove Bohr inequalities for sense-preserving $K$-quasiconformal harmonic mappings defined in $\mathbb{D}$ and obtain the corresponding results for sense-preserving harmonic mappings by letting $K\to\infty$. One of the results includes the sharpened version of a theorem by Kayumov $\textit{et. al.}$ ($\textit{Math. Nachr.}$, 291 (2018), no. 11--12, 1757--1768). In addition Bohr inequalities have been established for uniformly locally univalent holomorphic functions, and for $\log(f(z)/z)$ where $f$ is univalent or inverse of a univalent function.

Proposal for a New Michelson-Morley Experiment Using a Single Whispering Spherical Mode Resonator

description: A new Michelson-Morley experiment is proposed by measuring the beat frequency of two near degenerate modes with orthogonal propagation in a single spherical resonator. The unique properties of the experiment allow: 1. Substantial common mode rejection of some noise sources: 2. Simple calculation of the signal if Special Relativity is violated. We show that optimum filtering may be used to increase the signal to noise ratio, and to search for a preferred direction of the speed of light. Using this technique we show that a sensitivity limit of order 7.10^-19 is possible by integrating data over one month. We propose methods to veto systematic effects by correlating the output of more than one experiment.
