Coexistence of species in a fluctuating environment
Creators: name: Fitzpatrick, Gordon James
Publisher: name: University of British Columbia
Year: 2010

description: A dynamic model in which multiple consumers of a single nutrient may coexist in a fluctuating environment is given. Only one consumer can persist in a fixed environment, but coexistence may be produced by effects of a fluctuating environmental variable on nutrient utilization differing between consumers. An approximate solution is given for the non-autonomous Lotka-Volterra-Verhulst ordinary differential equations of the model together with heuristic sufficient conditions for construction of a persistent multispecies consumer community. Computational examples demonstrate persistence of an idealized example community for periodic and random environmental fluctuation. Two further examples demonstrate that environmental fluctuation can produce coexistence when environmental variables, standing crops, assimilation efficiencies, primary productivity, utilization rates, and respiration rates are comparable to a tropical grassland, and an oligotrophic temperate lake. The sensitivity of model solutions to functional variations of the component species may be rapidly and accurately calculated. This allows the identification and estimation of unknown species functional responses from time series data of biomasses and a measured environmental variable. Unknown functions of an environmental variable are approximated by a Tchebycheff polynomial expansion in that variable. Unknown coefficients of these expansions are the parameters of the model. These parameters are determined by the unconstrained minimization of the squared deviations of the logarithm of biomass observations and model differential equation solution using a Quasi-Newton algorithm. This least squares estimator was applied to a one year biomass time series of four zooplankton grazers, phytoplankton, and average lake temperature of a small oligotrophic lake. Application of the model to this grazer zooplankton community gives evidence of partial stabilization due to environmental fluctuation in a natural community. It is concluded that environmental variation, which is often assumed on theoretical grounds to be destabilizing, should rather be considered as one of the bases of community persistence.
Is null-point reconnection important for solar flux emergence?

description: The role of null-point reconnection in a 3D numerical MHD model of solar emerging flux is investigated. The model consists of a twisted magnetic flux tube rising through a stratified convection zone and atmosphere to interact and reconnect with a horizontal overlying magnetic field in the atmosphere. Null points appear as the reconnection begins and persist throughout the rest of the emergence, where they can be found mostly in the model photosphere and transition region, forming two loose clusters on either side of the emerging flux tube. Up to 26 nulls are present at any one time, and tracking in time shows that there is a total of 305 overall, despite the initial simplicity of the magnetic field configuration. We find evidence for the reality of the nulls in terms of their methods of creation and destruction, their balance of signs, their long lifetimes, and their geometrical stability. We then show that due to the low parallel electric fields associated with the nulls, null-point reconnection is not the main type of magnetic reconnection involved in the interaction of the newly emerged flux with the overlying field. However, the large number of nulls implies that the topological structure of the magnetic field must be very complex and the importance of reconnection along separators or separatrix surfaces for flux emergence cannot be ruled out.

description: Quality assessment of agricultural produce is a crucial step in minimizing food stock wastage. However, this is currently done manually and often requires expert supervision, especially in smaller seeds like corn. We propose a novel computer vision-based system for automating this process. We build a novel seed image acquisition setup, which captures both the top and bottom views. Dataset collection for this problem has challenges of data annotation costs/time and class imbalance. We address these challenges by i.) using a Conditional Generative Adversarial Network (CGAN) to generate real-looking images for the classes with lesser images and ii.) annotate a large dataset with minimal expert human intervention by using a Batch Active Learning (BAL) based annotation tool. We benchmark different image classification models on the dataset obtained. We are able to get accuracies of up to 91.6% for testing the physical purity of seed samples.
title: Hydrodynamics can determine the optimal route for microswimmer navigation

description: As compared to the well explored problem of how to steer a macroscopic agent, like an airplane or a moon lander, to optimally reach a target, optimal navigation strategies for microswimmers experiencing hydrodynamic interactions with walls and obstacles are far-less understood. Here, we systematically explore this problem and show that the characteristic microswimmer-flow-field crucially influences the navigation strategy required to reach a target in the fastest way. The resulting optimal trajectories can have remarkable and non-intuitive shapes, which qualitatively differ from those of dry active particles or motile macroagents. Our results provide insights into the role of hydrodynamics and fluctuations on optimal navigation at the microscale, and suggest that microorganisms might have survival advantages when strategically controlling their distance to remote walls.
Quantum boolean functions

description: In this paper we introduce the study of quantum boolean functions, which are unitary operators f whose square is the identity: f^2 = I. We describe several generalisations of well-known results in the theory of boolean functions, including quantum property testing; a quantum version of the Goldreich-Levin algorithm for finding the large Fourier coefficients of boolean functions; and two quantum versions of a theorem of Friedgut, Kalai and Naor on the Fourier spectra of boolean functions. In order to obtain one of these generalisations, we prove a quantum extension of the hypercontractive inequality of Bonami, Gross and Beckner.

Subjects: AGR/16 Microbiologia agraria

description: 60 strains (belonging to the genera Lactobacillus, Bifidobacterium, Leuconostoc and Enterococcus) were tested for their capacity to inhibit the growth of 3 strains of Campylobacter jejuni: Lactobacilli and bifidobacteria were left to grow in MRS or TPY broth at 37°C overnight in anaerobic conditions; Campylobacter jejuni was inoculated in blood agar plates at 37°C for 24-48 hours in microaerophilic conditions.
The inhibition experiments were carried out in vitro using ”Spot agar test” and “Well diffusion assay” techniques testing both cellular activity and that of the surnatant. 
11 strains proved to inhibit the growth of Campylobacter jejuni. These strains were subsequently analised analised in order to evaluate the resistance to particular situations of stress which are found in the gastrointestinal tract and during the industrial transformation processes (Starvation stress, osmotic stress, heat stress, resistance to pH and to bile salts).
Resistance to starvation stress: all strains seemed to resist the stress (except one strain).
Resistance to osmotic stress: all strains were relatively resistant to the concentrations of 6% w/v of NaCl (except one strain).
Resistance to heat stress: only one strain showed little resistance to the 55°C temperature. 
Resistance to pH: In the presence of a low pH (2.5), many strains rapidly lost their viability after approximately 1 hour.
Resistance to bile salts: Except for one strain, all strains seemed to be relatively resistant to the 2% w/v concentration of bile salts.
Afterward, strains were identified by using phenotipic and molecular techniques.
Phenotipic identification was carried out by using API 50 CHL (bioMérieux) and API 20 STREP identification system (bioMérieux); molecular identification with species-specific PCR: the molecular techniques confirmed the results by phenotipic identification.
For testing the antibiotic resistance profile, bacterial strains were subcultured in MRS or TPY broth and incubated  for 18 h at 37°C under anaerobic conditions. Antibiotics tested (Tetracycline, Trimethoprim, Cefuroxime, Kanamycin, Chloramphenicol, Vancomycin, Ampycillin, Sterptomycin, Erythromycin) were diluted to the final concentrations of: 2,4,8,16,32,64,128,256 mg/ml. Then, 20 μl fresh bacterial culture (final concentration in the plates approximately 106 cfu/ml) were added to 160 μl MRS or TPY broth and 20 μl antibiotic solution. As positive control the bacterial culture (20 ul) was added to broth (160 ul) and water (20 ul). 
Test was performed on plates P96, that after the inoculum were incubated for 24 h at 37oC, then the antibiotic resistance was determined by measuring the Optical Density (OD) at 620 nm with Multiscan EX. All strains showed a similar behaviour: resistance to all antibiotic tested. Further studies are needed.

description: An article published on Medical News Today in June 2022 presented a fundamental question in its title: Can an earlobe crease predict heart attacks? The author explained that end arteries supply the heart and ears. In other words, if they lose blood supply, no other arteries can take over, resulting in tissue damage. Consequently, some earlobes have a diagonal crease, line, or deep fold that resembles a wrinkle. In this paper, we take a step toward detecting this specific marker, commonly known as DELC or Frank's Sign. For this reason, we have made the first DELC dataset available to the public. In addition, we have investigated the performance of numerous cutting-edge backbones on annotated photos. Experimentally, we demonstrate that it is possible to solve this challenge by combining pre-trained encoders with a customized classifier to achieve 97.7% accuracy. Moreover, we have analyzed the backbone trade-off between performance and size, estimating MobileNet as the most promising encoder.

description: Excerpt from the report: The objective of this study is to define an attainable high-level food consumption for the United States and to estimate the quantities of food involved. The definition of high-level food consumption developed here takes into account two principal considerations: (1) What foods people need nutritionally to sustain good health and (2) what foods people would like to consume as indicated by consumption in the higher income brackets. In brief, the measure of high-level food consumption for each individual is simply the higher rate of consumption obtained in the comparison between the estimated actual consumption and the minimum nutritional requirement. The implications of achieving the high level of food consumption are then analyzed: (1) To determine the effect on American dietaries, (2) to ascertain the income effects to the national economy and to agriculture. (3) to obtain a rough measure of the production adjustments involved. Finally, ways and means of achieving the high level of food consumption are reviewed and discussed.

description: We present a pilot search of CO emission in three H$_2$-absorbing, long-duration gamma-ray burst (GRB) host galaxies at z~2-3. We used the Atacama Large Millimeter/sub-millimeter Array (ALMA) to target the CO(3-2) emission line and report non-detections for all three hosts. These are used to place limits on the host molecular gas masses, assuming a metallicity-dependent CO-to-H$_2$ conversion factor ($α_{\rm CO}$). We find, $M_{\rm mol} < 3.5\times 10^{10}\,M_{\odot}$ (GRB\,080607), $M_{\rm mol} < 4.7\times 10^{11}\,M_{\odot}$ (GRB\,120815A), and $M_{\rm mol} < 8.9\times 10^{11}\,M_{\odot}$ (GRB\,181020A). The high limits on the molecular gas mass for the latter two cases are a consequence of their low stellar masses $M_\star$ ($M_\star \lesssim 10^{8}\,M_{\odot}$) and low gas-phase metallicities ($Z\sim 0.03\,Z_{\odot}$). The limit on the $M_{\rm mol}/M_\star$ ratio derived for GRB\,080607, however, is consistent with the average population of star-forming galaxies at similar redshifts and stellar masses. We discuss the broader implications for a metallicity-dependent CO-to-H$_2$ conversion factor, and demonstrate that the canonical Galactic $α_{\rm CO}$, will severely underestimate the actual molecular gas mass for all galaxies at $z>1$ with $M_\star < 10^{10}\,M_\odot$. To better quantify this we develop a simple approach to estimate the relevant $α_{\rm CO}$ factor based only on the redshift and stellar mass of individual galaxies. The elevated conversion factors will make these galaxies appear CO-"dark" and difficult to detect in emission, as is the case for the majority of GRB hosts. GRB spectroscopy thus offers a complementary approach to identify low-metallicity, star-forming galaxies with abundant molecular gas reservoirs at high redshifts that are otherwise missed by current ALMA surveys.

description: Stable cross-sections of multi-walled carbon nanotubes subjected to electron-beam irradiation are investigated in the realm of the continuum mechanics approximation. The self-healing nature of sp$^2$ graphitic sheets implies that selective irradiation of the outermost walls causes their radial shrinkage with the remaining inner walls undamaged. The shrinking walls exert high pressure on the interior part of nanotubes, yielding a wide variety of radial corrugation patterns ({\it i.e.,} circumferentially wrinkling structures) in the cross section. All corrugation patterns can be classified into two deformation phases for which the corrugation amplitudes of the innermost wall differ significantly.

In the second section, as part of a larger canid genome project, we will exploit NGS data to investigate the transcript-level differences between the wolf and the dog genome that can be correlated to domestication.
Tukey-order with models on Pawlikowski's theorems

description: In J. Symbolic Logic,51(4): 957-968, 1986, Pawlikowski proved that, if $r$ is a random real over $\mathbf{N}$, and $c$ is Cohen real over $\mathbf{N}[r]$, then (a) in $\mathbf{N}[r][c]$ there is a Cohen real over $\mathbf{N}[c]$, and (b) $2^ω\cap\mathbf{N}[c]\notin\mathcal{N}\cap\mathbf{N}[r][c]$, so in $\mathbf{N}[r][c]$ there is no random real over $\mathbf{N}[c]$. To prove this, Pawlikowski proposes the following notion: Given two models $\mathbf{N}\subseteq \mathbf{M}$ of ZFC, we associate with a cardinal characteristic $\mathfrak{x}$ of the continuum, a sentence $\mathfrak{x}_\mathbf{N}^\mathbf{M}$ saying that in $\mathbf{M}$, the reals in $\mathbf{N}$ give an example of a family fulfilling the requirements of the cardinal. So to prove (a) and (b), it suffices to prove that (a') $\mathrm{cov}(\mathcal{M})_{\mathbf{N}[c]}^{\mathbf{M}[c]}\Rightarrow\mathrm{cof}(\mathcal{M})_{\mathbf{N}}^{\mathbf{M}}\Rightarrow\mathrm{cov}(\mathcal{N})_{\mathbf{N}}^{\mathbf{M}}$, and (b') $\mathrm{cov}(\mathcal{M})_\mathbf{N}^\mathbf{M}\Rightarrow\mathrm{add}(\mathcal{M})_{\mathbf{N}}^{\mathbf{M}}\Rightarrow\mathrm{non}(\mathcal{M})_{\mathbf{N}[c]}^{\mathbf{M}[c]}\Rightarrow\mathrm{cov}(\mathcal{N})_{\mathbf{N}[c]}^{\mathbf{M}[c]}$. In this paper, we introduce the notion of Tukey-order with models, which expands the concept of Tukey-order introduced by Vojtáš (Israel Math. Conf. Proc. 6: 619-643, 1991) to prove expressions of the form $\mathfrak{x}_\mathbf{N}^\mathbf{M}\Rightarrow\mathfrak{y}_\mathbf{N}^\mathbf{M}$. In particular, we show (a') and (b') using Tukey-order with models.

description: In this paper, a dynamic-programming approach to the coupled translational and rotational control of thruster-driven spacecraft is studied. To reduce the complexity of the problem, dynamic-programming-based optimal policies are calculated using decoupled position and attitude dynamics with generalized forces and torques as controls. A quadratic-programming-based control allocation is then used to map the controls to actuator commands. To control the spacecraft in the event of thruster failure, both the dynamic programming policies and control allocation are reconfigured to cope with the losses in controls. The control allocation parameters are adjusted dynamically to ensure the satellite always approaches the target from the side with two operative thrusters to achieve a stable control. The effectiveness of the proposed dynamic programming control is compared with a Lyapunov-stable control method, which shows that the proposed method is more fuel-efficient in tracking the same path.

description: We study flavour violation in a supersymmetric SO(10) implementation of the type II seesaw mechanism, which provides a predictive realization of triplet leptogenesis. The experimental upper bounds on lepton flavour violating processes have a significant impact on the leptogenesis dynamics, in particular they exclude the strong washout regime. Requiring successful leptogenesis then constrains the otherwise largely unknown overall size of flavour-violating observables, thus yielding testable predictions. In particular, the branching ratio for mu -> e gamma lies within the reach of the MEG experiment if the superpartner spectrum is accessible at the LHC, and the supersymmetric contribution to epsilon_K can account for a significant part of the experimental value. We show that this scenario can be realized in a consistent SO(10) model achieving gauge symmetry breaking and doublet-triplet splitting in agreement with the proton decay bounds, improving on the MSSM prediction for alpha_3(m_Z), and reproducing the measured quark and lepton masses.

Rain attenuation at 74 Ghz
Creators: name: McNicol, John Duncan
Publisher: name: University of British Columbia
Year: 2010

description: A millimetric wave transmission link of the radar type has been established at the University of British Columbia campus. It operates at 74 GHz and has a 1.8 km total transmission length. The RF source is an unmodulated klystron and a phase-locked receiver is used to detect the received signal. The main objective is to measure the excess path attenuation due to precipitation. For this purpose a weather station has been constructed. It consists of 5 tipping-bucket rain gauges distributed along the path and apparatus for the measurement of temperature and wind velocity. The level of the microwave signal and the outputs of the weather sensors are transmitted to a central station. There, initial processing and data recording on magnetic tape are performed on a continuous basis by a Nova 840 minicomputer. Subsequently, data is further processed on an IBM 370. Of the 1400 hours of data recorded during a four month period, approximately 25 hours included simultaneous rain and microwave data and were sufficiently "reliable" to analyse. The processed experimental data are compared with the theory of Ryde and Ryde over the range of rain rates observed (0 to 10 mm/hour).

description: Reading code is an essential activity in software maintenance and evolution. Several studies with human subjects have investigated how different factors, such as the employed programming constructs and naming conventions, can impact code readability, i.e., what makes a program easier or harder to read and apprehend by developers, and code legibility, i.e., what influences the ease of identifying elements of a program. These studies evaluate readability and legibility by means of different comprehension tasks and response variables. In this paper, we examine these tasks and variables in studies that compare programming constructs, coding idioms, naming conventions, and formatting guidelines, e.g., recursive vs. iterative code. To that end, we have conducted a systematic literature review where we found 54 relevant papers. Most of these studies evaluate code readability and legibility by measuring the correctness of the subjects' results (83.3%) or simply asking their opinions (55.6%). Some studies (16.7%) rely exclusively on the latter variable.There are still few studies that monitor subjects' physical signs, such as brain activation regions (5%). Moreover, our study shows that some variables are multi-faceted. For instance, correctness can be measured as the ability to predict the output of a program, answer questions about its behavior, or recall parts of it. These results make it clear that different evaluation approaches require different competencies from subjects, e.g., tracing the program vs. summarizing its goal vs. memorizing its text. To assist researchers in the design of new studies and improve our comprehension of existing ones, we model program comprehension as a learning activity by adapting a preexisting learning taxonomy. This adaptation indicates that some competencies are often exercised in these evaluations whereas others are rarely targeted.

description: Gap solitons near a band edge of a spatially periodic nonlinear PDE can be formally approximated by solutions of Coupled Mode Equations (CMEs). Here we study this approximation for the case of the 2D Periodic Nonlinear Schrödinger / Gross-Pitaevskii Equation with a non-separable potential of finite contrast. We show that unlike in the case of separable potentials [T. Dohnal, D. Pelinovsky, and G. Schneider, J. Nonlin. Sci. {\bf 19}, 95--131 (2009)] the CME derivation has to be carried out in Bloch rather than physical coordinates. Using the Lyapunov-Schmidt reduction we then give a rigorous justification of the CMEs as an asymptotic model for reversible non-degenerate gap solitons and even potentials and provide $H^s$ estimates for this approximation. The results are confirmed by numerical examples including some new families of CMEs and gap solitons absent for separable potentials.

description: We model a quantum sensor network using techniques from quantum state discrimination. The interaction between a qubit detector and the environment is described by a unitary operator, and we will assume that at most one detector does interact. The task is to determine which one does or if none do. This involves choosing an initial state of the detectors and a measurement. We consider global measurements in which all detectors are measured simultaneously. We find that an entangled initial state can improve the detection probability, but this advantage decreases as the number of detectors increases.

Subjects: FIS/05 Astronomia e astrofisica

description: The quality of astronomical sites is the first step to be considered to have the best performances from the telescopes. In particular, the efficiency of large telescopes in UV, IR, radio etc. is critically dependent on atmospheric transparency. It is well known that the random optical effects induced on the light propagation by turbulent atmosphere also limit telescope’s performances. Nowadays, clear appears the importance to correlate the main atmospheric physical parameters with the optical quality reachable by large aperture telescopes. The sky quality evaluation improved with the introduction of new techniques, new instrumentations and with the understanding of the link between the meteorological (or synoptical parameters and the observational conditions thanks to the application of the theories of electromagnetic waves propagation in turbulent medias: what we actually call astroclimatology. At the present the site campaigns are evolved and are performed using the classical scheme of optical seeing properties, meteorological parameters, sky transparency, sky darkness and cloudiness. New concept are added and are related to the geophysical properties such as seismicity, microseismicity, local variability of the climate, atmospheric conditions related to the ground optical turbulence and ground wind regimes, aerosol presence, use of satellite data. The purpose of this project is to provide reliable methods to analyze the atmospheric properties that affect ground-based optical astronomical observations and to correlate them with the main atmospheric parameters generating turbulence and affecting the photometric accuracy. The first part of the research concerns the analysis and interpretation of longand
short-time scale meteorological data at two of the most important astronomical sites located in very different environments: the Paranal Observatory in the Atacama Desert (Chile), and the Observatorio del Roque de Los Muchachos(ORM) located in La Palma (Canary Islands, Spain). The optical properties of airborne dust at ORM have been investigated collecting outdoor data using a ground-based dust monitor. Because of its dryness, Paranal is a suitable observatory for near-IR observations, thus the extinction properties in the spectral range 1.00-2.30 um have been investigated using an empirical method. Furthermore, this PhD research has been developed using several turbulence profilers in the selection of the site for the European Extremely Large Telescope(E-ELT). During the campaigns the properties of the turbulence at different heights at Paranal and in the sites located in northern Chile and Argentina have been studied. This given the possibility to characterize the surface layer turbulence at Paranal and its connection with local meteorological conditions.
CTbend: A Bayesian open-source framework to model pointing corrections for Cherenkov telescopes

description: The pointing of Cherenkov telescopes is subject to imperfections which are, for example, related to the bending of the telescopes mechanical structure. These imperfections must be measured, modeled, and finally corrected to achieve an optimal telescope pointing precision. The measurement of pointing deviations is often performed while the telescope points to different stars and a CCD camera monitors the offsets of the star images to the center of the focal plane. Outliers in these measurements can propagate into the pointing model and lead to imprecise model predictions. CTbend is a simple and standalone open-source framework that uses a Bayesian analysis with an outlier resilient likelihood function to model the pointing of Cherenkov telescopes with parametric standard models like TPoint. The framework is described in the following.

Slow-roll inflation with a Gauss-Bonnet correction

description: We consider slow-roll inflation for a single scalar field with an arbitrary potential and an arbitrary nonminimal coupling to the Gauss-Bonnet term. By introducing a combined hierarchy of Hubble and Gauss-Bonnet flow functions, we analytically derive the power spectra of scalar and tensor perturbations. The standard consistency relation between the tensor-to-scalar ratio and the spectral index of tensor perturbations is broken. We apply this formalism to a specific model with a monomial potential and an inverse monomial Gauss-Bonnet coupling and constrain it by the 7-year Wilkinson Microwave Anisotropy Probe data. The Gauss-Bonnet term with a positive (or negative) coupling may lead to a reduction (or enhancement) of the tensor-to-scalar ratio and hence may revive the quartic potential ruled out by recent cosmological data.

Hereditary transthyretin-related amyloidosis: clinical and physiopathologic profile and natural history

Subjects: MED/11 Malattie dell'apparato cardiovascolare

description: Background. Hereditary transthyretin (TTR)-related amyloidosis (ATTR) is mainly considered a neurologic disease. We assessed the phenotypic and genotypic spectrum of ATTR in a non-endemic, Caucasian area and evaluated  prevalence, genetic background and disease profile of cases with an exclusively cardiac phenotype, highlighting possible hints for the differential diagnosis with hypertrophic cardiomyopathy (HCM) and senile systemic amyloidosis (SSA)  
Methods and Results. In this Italian multicenter study, 186 patients with ATTR were characterized at presentation. Thirty patients with SSA and 30 age-gender matched HCM patients were used for comparison. Phenotype was classified as: exclusively cardiac (n= 31, 17%), exclusively neurologic (n= 46, 25%), mixed cardiac/neurologic (n=109, 58%).  
Among the 8 different mutations responsible for an exclusively cardiac phenotype, Ile68Leu was the most frequent (23/31). Five patients with an exclusively cardiac phenotype developed mild abnormalities at neurological examination but no symptoms during a 36 [14−50] month follow-up. Exclusively cardiac phenotype was characterized by male gender, age > 65 years, heart failure symptoms, concentric left ventricular (LV) “hypertrophy” and moderately depressed LV ejection fraction. This profile was similar to SSA but relatively distinct from HCM. Compared to patients with a mixed phenotype, patients with a exclusively cardiac phenotype showed a more pronounced cardiac involvement on both echocardiogram and ECG.  
Conclusion. A clinically relevant subset of Caucasian ATTR patients present with an exclusively cardiac phenotype, mimicking HCM or SSA. Echocardiographic and ECG findings are useful to differentiate  ATTR from  HCM but not  from SSA. The role of liver transplantation in these patients is questionable.

Fast load flow algorithms
Creators: name: Jalali-Kushki, Hossein
Publisher: name: University of British Columbia
Year: 2010

description: New, fast and reliable algorithms for solving load-flow problems are presented in this thesis. Each of these algorithms iteratively solves a set of linear equations in terms of voltage magnitude squared and phase angles, and converges onto the final solution in a few iterations. Although the line losses of the system are used in deriving the equations of the basic line-loss load-flow algorithm, knowledge of their (approximate) values is not a prerequisite to using the algorithm. The basic line-loss load-flow algorithm is slightly modified to give an incremental-change line-loss algorithm which proves to be always preferable to the basic algorithm. By exploiting the weak interdependence between active power and voltage magnitude, and between reactive power and phase angle, two decoupled versions of the incremental-change line-loss algorithm were also developed. All these algorithms have constant gradient characteristics, and their storage requirements are, at most, the same as those of the standard Newton-Raphson algorithm. If need be, the storage requirements can be reduced to those of the triangularized Y-matrix iterative algorithms. Tests on various systems indicate fast and reliable convergence characteristics better than those of the Newton-Raphson algorithm and comparable, to those obtained by Stott and Alsac with their decoupled Newton-Raphson load-flow algorithm.

description: We discuss the Pauli Hamiltonian including the spin-orbit interaction within an U(1) x SU(2) gauge theory interpretation, where the gauge symmetry appears to be broken. This interpretation offers new insight into the problem of spin currents in the condensed matter environment, and can be extended to Rashba and Dresselhaus spin-orbit interactions. We present a few outcomes of the present formulation: i) it automatically leads to zero spin conductivity, in contrast to predictions of Gauge symmetric treatments, ii) a topological quantization condition leading to voltage quantization follows, and iii) spin interferometers can be conceived in which, starting from a arbitrary incoming unpolarized spinor, it is always possible to construct a perfect spin filtering condition.

Electrosynthesis and characterization of structured catalysts

Year: 2012
Subjects: CHIM/01 Chimica analitica

description: In this research work the optimization of the electrochemical system of LDHs as catalytic precursors on FeCrAlY foams was carried out. 
Preliminary sintheses were performed on flat surfaces in order to easily characterize the deposited material. From the study of pH evolution vs time at different cathodic potentials applied to a Pt electrode, the theoretical best working conditions for the synthesis of single hydroxides and LDH compounds was achieved. 
In order to define the optimal potential for the synthesis of a particular LDH compound, the collected data were compared with the interval of precipitation determined by titration with NaOH. However, the characterization of the deposited material on Pt surfaces did not confirm the deposition of a pure  and homogeneous LDH phase during the synthesis. Instead a sequential deposition linked to the pH of precipitation of the involved elements is observed. The same behavior was observed during the synthesis of the RhMgAl LDH on FeCrAlY foam as catalytic precursor. Several parameters were considered in order to optimize the synthesis.. The development of electrochemical cells with different feature, such as the counter electrode dimensions or the contact between the foam and the potentiostat, had been carried out in order to obtain a better coating of the foam. The influence of the initial pH of the electrolyte solution, of the applied potential, of the composition of the electrolytic solution were investigated in order to improve a better coating of the catalyst support. Catalytic tests were performed after the calcination of the deposited foam for the CPO and SR reactions, showing an improve of performances along with optimization of the precursors synthesis conditions.
