description: An involution $#$ on an associative ring $R$ is \textit{formally real} if a sum of nonzero elements of the form $r^# r$ where $r \in R$ is nonzero. Suppose that $R$ is a central simple algebra (i.e. $R=M_n(D)$ for some integer $n$ and central division algebra $D$) and $#$ is an involution on $R$ of the form $r^# = a^{-1} r^\ast a$, where $\ast$ is some transpose involution on $R$ and $a$ is an invertible matrix such that $a^\ast=\pm a$. In section 1 we characterize formal reality of $#$ in terms of $a$ and $\ast|_D$. In later sections we apply this result to the study of formal reality of involutions on crossed product division algebras. We can characterize involutions on $D=(K/F,Φ)$ that extend to a formally real involution on the split algebra $D \otimes_F K \cong M_n(K)$. Every such involution is formally real but we show that there exist formally real involutions on $D$ which are not of this form. In particular, there exists a formally real involution $#$ for which the hermitian trace form $x \mapsto \tr(x^#x)$ is not positive semidefinite.

description: Using the Kubo formalism, we demonstrate fractional quantum Hall features in a rotating Bose-Einstein condensate in a co-rotating two-dimensional optical lattice. The co-rotating lattice and trap potential allow for an effective magnetic field and compensation of the centrifugal potential. Fractional quantum Hall features are seen for the single-particle system and for few strongly interacting many-particle systems.

description: This paper summarizes our recent progress towards using single rubidium atoms trapped in an optical tweezer to encode quantum information. We demonstrate single qubit rotations on this system and measure the coherence of the qubit. We move the quantum bit over distances of tens of microns and show that the coherence is reserved. We also transfer a qubit atom between two tweezers and show no loss of coherence. Finally, we describe our progress towards conditional entanglement of two atoms by photon emission and two-photon interferences.

The Fractal Distribution of HII Regions in Disk Galaxies

description: It is known that the gas has a fractal structure in a wide range of spatial scales with a fractal dimension that seems to be a constant around Df = 2.7. It is expected that stars forming from this fractal medium exhibit similar fractal patterns. Here we address this issue by quantifying the degree to which star-forming events are clumped. We develop, test, and apply a precise and accurate technique to calculate the correlation dimension Dc of the distribution of HII regions in a sample of disk galaxies. We find that the determination of Dc is limited by the number of HII regions, since if there are < 100 regions available then a bias tending to underestimate the dimension is produced. The reliable results are distributed in the range 1.5 < Dc < 2.0 with an average value Dc = 1.81. This corresponds to a three-dimensional dimension of Df = 2.73, very similar to the value measured in the interstellar clouds. However, we get significant variations in the fractal dimension among galaxies, contrary to a universal picture sometimes claimed in literature. The fractal dimension exhibits a weak but significant correlation with the absolute magnitude and, to a lesser extent, with the galactic radius. The faintest galaxies tend to distribute their HII regions in more clustered (less uniform) patterns. The fractal dimension for the brightest HII regions within the same galaxy seems to be smaller than for the faintest ones suggesting some kind of evolutionary efffect, but the obtained correlation remains unchanged if only the brightest regions are taken into account.

description: We investigate the most general conditions under which a finite ferromagnetic long-range inter- acting spin chain achieves unitary fidelity and the shortest transfer time in transmitting an unknown input qubit. A deeper insight into system dynamics, allows us to identify an ideal system involving sender and receiver only. However, this two-spin ideal chain is unpractical due to the rapid decrease of the coupling strength with the distance. Therefore, we propose an optimization scheme for ap- proaching the ideal behaviour, while keeping the interaction strength still reasonably high. The procedure is scalable with the size of the system and straightforward to implement.

description: Signal formation mechanism of Piezoresponse Force Microscopy of piezoelectric surface layers and thin films on stiff and elastically matched substrates is analyzed and thickness dependence of effective piezoelectric response, object transfer function components and Rayleigh two-point resolution are derived. Obtained exact series and simple Pade approximations can be applied for the effective piezoresponse analytical calculations in the case of films capped on different substrates. The effective piezoresponse is thickness dependent for piezoelectric films on substrates with low dielectric permittivity (extrinsic size effect), whereas the thickness dependence is essentially suppressed for giant permittivity or metallic substrates. Thus implications of analysis for ferroelectric data storage and device applications are discussed.

description: A direct observation of the giant Zeeman splitting of the free excitons in (Ga,Fe)N is reported. The magnetooptical and magnetization data imply the ferromagnetic sign and a reduced magnitude of the effective p-d exchange energy governing the interaction between Fe^{3+} ions and holes in GaN, N_0 beta^(app) = +0.5 +/- 0.2 eV. This finding corroborates the recent suggestion that the strong p-d hybridization specific to nitrides and oxides leads to significant renormalization of the valence band exchange splitting.

Molecular genetic analysis of the saccharomyces cerevisiae Mat Locus
Creators: name: Porter, Susan Dorothy
Publisher: name: University of British Columbia
Year: 2010

description: The MAT∝ locus of the yeast Saccharomyces cerevisiae encodes two regulatory proteins responsible for determining the ∝cell type. The MAT∝1 gene encodes ∝1, a positive regulator of ∝cell-specific genes, whereas the MAT∝2 gene encodes a negative regulator of a cell-specific genes (∝2). MAT∝2. (in conjunction with the MATα1 gene) also determines the α/∝ diploid cell type by repressing haploid-specific genes. ∝2 exerts its effect at the transcriptional level in the ∝ cell by binding to a sequence located upstream of α cell-specific genes. The present study undertook to examine, through in vitro genetic manipulation, the structure/function relationship of the MAT∝ regulatory proteins, particularly∝2, in their role as gene regulators. The construction of mutant MAT∝2 genes containing termination codons at various points within the gene, and subsequent transformation of the mutant genes into mat∝2 yeast, indicated that the carboxy-terminal one-third of the gene product was necessary for full repressor activity in the haploid as well as in the diploid. A segment within the carboxy-terminal one-third of ∝2 displays some homology to the higher eukaryote homeo domain as well as to a prokaryotic bihelical DNA-binding structural motif. This region of the gene was subjected to semi-random missense mutagenesis in vitro and the mutant genes were analyzed by transformation into strains containing chimaeric genes that encode β-galactosidase from ∝2 and a1/∝2. repressible promoters. In this manner it was demonstrated that most of those residues in ∝2. which correspond to conserved amino acids in the prokaryotic DNA-binding structure and in the homeo domain are essential for the two repressor activities of ∝2. Several mutations more severely affected the ability of ∝2 to repress α-specific genes than haploid-specific genes. Analysis of the temperature dependence of the activities of some of the mutants was consistent with the existence of a helix-turn-helix structure at this region of the protein. Finally, further analysis of some of these mutants in vitro confirmed that the observed defect correlated with a loss of DNA-binding activity.

description: We present numerical simulations of the SU(2) Boltzmann-Vlasov equation including both hard elastic particle collisions and soft interactions mediated by classical Yang-Mills fields. We provide an estimate of the coupling of jets to a hot isotropic plasma, which is independent of infrared cutoffs. In addition, we investigate jet propagation in anisotropic plasmas, as created in heavy-ion collisions. The broadening of jets is found to be stronger along the beam line than in azimuth due to the creation of field configurations with B_t>E_t and E_z>B_z via plasma instabilities.

description: We show that quantum-interference-related phenomena, such as electromagnetically induced transparency, gain without inversion and enhanced refractive index may occur on electric-dipole forbidden transitions. Gain/dispersion characteristics of such transitions strongly depend upon the relative phase between the driving and probe fields. Unlike allowed transitions, gain/absorption behavior of forbidden transitions exhibit antisymmetric feature on the Rabi sidebands. Absorption/gain spectra possess extremely narrow sub-natural resonances.

Spitzer Space Telescope evidence in NGC 6791: no super-mass-loss at super-solar metallicity to explain helium white dwarfs?

description: We use archival Spitzer Space Telescope photometry of the old, super-solar metallicity massive open cluster NGC 6791 to look for evidence of enhanced mass loss, which has been postulated to explain the optical luminosity function and low white dwarf masses in this benchmark cluster. We find a conspicuous lack of evidence for prolificacy of circumstellar dust production that would have been expected to accompany such mass loss. We also construct the optical and infrared luminosity functions, and demonstrate that these fully agree with theoretical expectations. We thus conclude that there is no evidence for the mass loss of super-solar metallicity red giants to be sufficiently high that they can avoid the helium flash at the tip of the red giant branch.

description: We conduct spectral observations of 138 superthin galaxies (STGs) with high radial-to-vertical stellar disk scales ratio with the Dual Imaging Spectrograph (DIS) on the 3.5m telescope at the Apache Point Observatory (APO) to obtain the ionized gas rotation curves with R ~ 5000 resolution. We also performed near infrared (NIR) H and Ks photometry for 18 galaxies with the NICFPS camera on the 3.5m telescope. The spectra, the NIR photometry and published optical and NIR photometry are used for modeling that utilizes the thickness of the stellar disk and rotation curves simultaneously. The projection and dust extinction effects are taken into account. We evaluate eight models that differ by their free parameters and constraints. As a result, we estimated masses and scale lengths of the galactic dark halos. We find systematic differences between the properties of our red and blue STGs. The blue STGs have a large fraction of dynamically under-evolved galaxies whose vertical velocity dispersion is low in both gas and stellar disks. The dark halo-to-disk scale ratio is shorter in the red STGs than in the blue ones, but in a majority of all STGs this ratio is under 2. The optical color $(r-i)$ of the superthin galaxies correlates with their rotation curve maximum, vertical velocity dispersion in stellar disks, and mass of the dark halo. We conclude that there is a threshold central surface density of 50 $M_{\odot}$\,pc$^{-2}$ below which we do not observe very thin, rotationally supported galactic disks.

description: We present a new approach to noncommutative real algebraic geometry based on the representation theory of $C^\ast$-algebras. An important result in commutative real algebraic geometry is Jacobi's representation theorem for archimedean quadratic modules on commutative rings, \cite[Theorem 5]{jacobi}. We show that this theorem is a consequence of the Gelfand-Naimark representation theorem for commutative $C^\ast$-algebras. A noncommutative version of Gelfand-Naimark theory was studied by I. Fujimoto. We use his results to generalize Jacobi's theorem to associative rings with involution.

description: Building-integrated photovoltaic (BIPV) technology has the potential to significantly contribute to the achievement of the demanding energy efficiency targets set by the EU, however, its market uptake has been hindered by the difficulties of the industry in providing holistic solutions complying with key demands from decision makers and endusers. This market deployment depends critically on the achievement of ambitious targets in terms of cost reduction, flexibility of design, high performance, reliability, aesthetics, standardization and compliance with legal regulations. BIPVBOOST will implement medium-term cost reduction roadmaps, addressing the whole BIPV value chain and will demonstrate in real operation conditions the contribution of the technology towards mass realization of nearly Zero Energy Buildings. BIPVBOOST will therefore contribute to lowering the cost of multifunctional BIPV systems, limiting the overall cost with respect to traditional, non-PV, construction solutions and non-integrated PV modules. At least 17 demonstrated innovative solutions will result from the successful implementation of the BIPVBOOST project. Together with the large involvement from industrial partners in the consortium, a sound basis will be to pursuit a 50% reduction of additional cost of BIPV modules in 2020 and 75% reduction in 2030, and thus a substantial increase of market deployment of BIPV technology.

description: In this work, an analytical model is presented that reproduces lateral changes in pn-junction voltage as a result of recombination at linear shaped defect. The model takes into account the majority charge carrier transport in the emitter and in the base as induced by a metal finger, an edge or any linear region with a high local recombination rate. It predicts the pn-junction voltage as a function of distance to the perturbation in one dimension. A comparison of the model with numerical device simulations using Quokka3 shows low deviation for the local voltage under the finger (< 2 mV) and at the edge (< 5 mV). The presented method to interpret the photoluminescence image of a wafer with a metal front grid is based on Fourier analysis. For each saturation current density at the metal, we can associate a predicted Fourier peak set obtained from the model. The saturation current density at the metal finger is obtained when the peaks of the photoluminescence image and the model correspond best. The model is also applied to the interpretation of photoluminescence images in the aim of evaluating the local saturation current density at the edge. In this case, photoluminescence images of the wafer edges are carried out at different illumination intensities. The pn-junction voltage profile towards the edge is calculated from the photoluminescence image of the wafer. For each illumination intensity, the saturation current density at the edge is obtained by adjusting the parameter of the model to the photoluminescence image. Finally, we obtain the saturation current density at the edge as a function of the carrier injection.

description: The study was conducted to characterize farm mechanization and determine its economic effects on rice production, income and employment. Ninety rice farmers were randomly selected and classified into three types: high, intermediate, and low-mechanized farms. The results of the study show that highly mechanized farms commonly own pumps, hand tractors, power tillers, and threshers while low mechanized farms tend to rent out their farm operations. The mean horsepower values tend to be higher in land preparation and threshing. The higher the level of mechanization, the higher the output and income per hectare: highly-mechanized farms with PhP 40,446; intermediate farms with PhP36,936; and low-mechanized farms, PhP 19,965. The study also reveals that farm mechanization has a negative effect on farm labor employment. Highly mechanized farms employ the lowest number of farm labor in man-days but employ the highest number of labor on post-production activity, specifically threshing.

description: Following the presentation of the XMM-LSS X-ray source detection package by Pacaud et al., we provide the source lists for the first 5.5 surveyed square degrees. The catalogues pertain to the [0.5-2] and [2-10] keV bands and contain in total 3385 point-like or extended sources above a detection likelihood of 15 in either band. The agreement with deep logN-logS is excellent. The main parameters considered are position, countrate, source extent with associated likelihood values. A set of additional quantities such as astrometric corrections and fluxes are further calculated while errors on the position and countrate are deduced from simulations. We describe the construction of the band-merged catalogue allowing rapid sub-sample selection and easy cross-correlation with external multi-wavelength catalogues. A small optical CFHTLS multi-band subset of objects is associated wich each source along with an X-ray/optical overlay. We make the full X-ray images available in FITS format. The data are available at CDS and, in a more extended form, at the Milan XMM-LSS database.

description: This paper investigates the relationship between retail and wholesale prices of milkfish (Chanoschanos), tilapia (Tilapianilotica), and tiger prawn (Peneaus monodon) using techniques that recognize the role of seasonal factors for testing orders of integration of and the existence of cointegration between these prices. This paper finds that seasonality plays an important role in explaining movements in the prices of these farmed species. This is so because, with the exception of the wholesale price of tiger prawn, unit roots occur at all frequencies for all of the prices that were examined. None of the pairs of prices were found to be cointegrated at all frequencies. However, the retail and wholesale prices of tilapia were found to be cointegrated at zero and annual frequencies. These findings suggest that regressions on the levels of retail and wholesale prices of milkfish and tiger prawn could lead to spurious results. Hence, price formation based on level of prices for these two aquaculture species can send wrong signals to the market stakeholders, i.e., producers, middlemen, and consumers.

description: Generalized parton distributions (GPDs) provide a new and powerful framework for a complete description of the nucleon structure. They can provide a three-dimensional picture of how the quarks and gluons form a nucleon. GPDs can be probed experimentally in hard exclusive meson production or deeply virtual Compton scattering (DVCS). The COMPASS experiment at CERN is a unique place to study these reactions. At COMPASS, a high energy polarized positive or negative muon beam is scattered off a polarized or unpolarized fixed target. First results for exclusive rho^0 meson production are shown. The transverse target spin asymmetry for exclusively produced rho^0 on a transversely polarized deuteron target has been measured. Prospects for future measurements of DVCS and exclusive meson production at COMPASS will be shown. The experiment will use the existing COMPASS spectrometer with a new target, a new recoil detector and extended calorimetry. Simulations for different models and a test of the recoil detector have been performed.

Here, we present a new 'balanced estimator' for entropy functionals Shannon, Rényi and Tsallis) specially devised to provide a compromise between low bias and small statistical errors, for short data series. This new estimator out-performs other currently available ones when the data sets are small and the probabilities of the possible outputs of the random variable are not close to zero. Otherwise, other well-known estimators remain a better choice. The potential range of applicability of this estimator is quite broad specially for biological and digital data series.

description: For pulsars in globular clusters, we suggest using observations of the relativistic time delay of their radiation in the gravitational eld of a massive body (the Shapiro effect) located close to the line of sight to detect and identify invisible compact objects and to study the distribution of both visible and dark matter in globular clusters and various components of the Galaxy. We have derived the dependences of the event probability on the Galactic latitude and longitude of sources for two models of the mass distribution in the Galaxy: the classical Bahcall-Soneira model and the more recent Dehnen-Binney model. Using three globular clusters (M15, 47 Tuc, Terzan 5) as an example, we show that the ratios of the probability of the events due to the passages of massive Galactic objects close to the line of sight to the parameter f2 for pulsars in the globular clusters 47 Tuc and M15 are comparable to those for close passages of massive objects in the clusters themselves and are considerably higher than those for the cluster Terzan 5. We have estimated the rates of such events. We have determined the number of objects near the line of sight toward the pulsar that can produce a modulation of its pulse arrival times characteristic of the effect under consideration; the population of brown dwarfs in the Galactic disk, whose concentration is comparable to that of the disk stars, has been taken into account for the first time.

description: In this work we present SIMS and ECV analysis to study the junction profile of selective emitter after a treatment by 532 nm laser. Initial emitter is obtained in low pressure diffusion tube of POCL3 and has a junction depth of 0.463µm and surface concentration of 1.32 1020 cm-3. Different laser intensity are used to optimize the final profile of selective emitter. The junctions are characterized by four point probe for sheet resistance measurement and their profile measured by SIMS and ECV. In the wide spectra of laser intensity used, from 2.8 to 6A corresponding to a power of 0.02 to 0.70W, we have found the optimized profile to use in the solar cell structure. Surface concentration profile and junction depth are compared for each laser treatment with the as diffused profile.

description: In this work, the partially-firing-through pastes which offer a shallow contact with silver incompletely penetrate through the poly-Si layer in tunnel oxide passivated contact (TOPCon) solar cells were investigated. The relevance between firing peak temperature and penetration depth of silver metallization, and the interface between Ag and poly-Si were studied by using transmission electron microscopy (TEM) and energy dispersive X-Ray spectroscopy (EDX). Transmission line measurement (TLM) was applied for contact resistance measurement of Ag-Si, and the lowest average contact resistance as low as 2.7 mΩ.cm2. To evaluate the quality of poly-Si/SiOx passivated contacts (also well-known as the carrier-selective contacts), the poly-Si films prepared with various PH3/SiH4 flow ratios were characterized by quasi steady-state photo conductance (QSSPC) measurement, the best passivation quality was obtained with a PH3/SiH4 flow ratio of 0.5:1 for giving an implied open-circuit voltage (iVoc) of 720 mV. Industrialsized TOPCon solar cells were fabricated by using various silver pastes, and the best cell prepared with a firing peak temperature of 740 °C achieved a conversion efficiency of 22.2%. The partially-firing-through silver pastes are proven to be promising candidates for firing metallization of poly-Si passivated solar cells.

description: Starting from a knowledge of certain identities in the Lagrangian description, the diffeomorphism transformations of metric and connection are obtained for both the second order (metric) and the first order (Palatini) formulations of gravity. The transformation laws of the connection and the metric are derived independently in the Palatini formulation in contrast to the metric formulation where the gauge variation of the connection is deduced from the gauge variation of the metric.

description: The concept of Open Science (OS) embraces a great number of practices targeted to promote more transparent and reproducible scientific processes. This, combined with the implementation of public engagement processes from the research community, drives us to a more collaborative and accesible science, where the chance of generating systemic and disruptive innovations can grow exponentially. In this work we show how a group of researchers have designed a methodology for assisting engineering researchers in the adoption of Open Science. This methodology is being applied along the full research cycle to produce six research outputs in the Photovoltaic (PV) field: a PV ageing model, an in-situ repairing methodology for PV modules, a PV-assisted irrigation system, PV heat pumps, a novel micro-concentrator system. and three-terminal tandem solar cells based on silicon and perovskites. We show how we are putting an Open Science approach into action in such research activities, so that PV innovations are better aligned with the society’s expectations, needs and values, enabling at the time more reproducible, transparent and collaborative science.

description: PV hybrid mini-grids have emerged as a viable solution for providing reliable, environmentally friendly electricity to remote communities. An affordable and grid-quality supply of electricity can open new possibilities for socioeconomic progress. As part of a joint program between South Africa and Germany’s state of Lower Saxony, a PV hybrid mini-grid is designed and developed in the municipality of Upper Blinkwater in Eastern Cape, South Africa Successful implementation of mini-grids requires the right technology, access to financing and consumer-friendly payment system, an appropriate regulatory environment, social facilitation, institutional implementation, environmental impact evaluation, human capitalization and training, and implementing a robust, reliable, and sustainable Monitoring and Evaluation Framework (MEF). The aim of this work is to design a systematic approach to the development of a sustainable MEF for PV hybrid mini-grids by integrating cutting-edge technologies and SMART methods in a scalable platform of replicable solutions towards connecting the mini-grid with diverse stakeholders with enhanced observability of both generation and consumption profiles.

description: To monitor massive multi-array operational plants in real-time, an inexpensive and effective monitoring system is indispensable. We propose an approach based on machine learning techniques which analyze historical power and irradiance data of PV arrays and do not require additional sensors. The developed system currently monitoring 150 plants including 7028 arrays is deployed on a Spark-cluster distributed platform such that the detection and diagnosis process can be finished within 5 minutes. The system demonstrates good performance. The fault detection accuracy is over 96%.

description: This study evaluated the level and distribution of educational attainments among male and female household heads in the Philippines. Estimates of average years of schooling (AYS) and education Gini coefficients show that the level and distribution of educational attainments for both subgroups were improving from 1991 to 2012. The study particularly found that females are becoming more educated than their counterparts at the turn of the millennium. Education Gini decomposition analysis then identified the withinmales educational disparity as the main contributor (about 59–73% contribution) to the country’s overall education inequality. Sex-disaggregated effects of education on the economic growth of Philippine provinces were also explored using panel and instrumental-variable (IV) regression analyses. Results suggest that improving both male and female schooling is growthenhancing, while it is growth-retarding for provinces with widening male-female AYSgap. And since the AYSgap has reversed in 2000, it is seen that the country would further reap economic benefits from a more-educated female workforce.

description: This paper looks into the relationship between typhoon exposure and inequality in per capita income and per capita expenditure of households in the Philippines by comparing the change in the Theil L and Theil T inequality indexes between 2009 and 2012 across different exposure groups. A decomposition analysis of the Theil index was also undertaken to establish the relative contributions of within-exposure group inequality and between-exposure groups inequality to total inequality. Conforming to the paper’s hypothesis, the group that has the highest exposure to typhoons was found to experience a worsening of both income and expenditure inequality while the group with the least exposure showed no change in expenditure inequality and an improvement in income equality. The result supports the importance of implementing policies that increase the resilience of local communities in the Philippines. Apart from short-term financial damages, exposure to adverse weather may also bring an added burden of worsening economic inequality.

Topologically Massive Gauge Theories and their Dual Factorised Gauge Invariant Formulation

description: There exists a well-known duality between the Maxwell-Chern-Simons theory and the self-dual massive model in 2+1 dimensions. This dual description has been extended to topologically massive gauge theories (TMGT) in any dimension. This Letter introduces an unconventional approach to the construction of this type of duality through a reparametrisation of the master theory action. The dual action thereby obtained preserves the same gauge symmetry structure as the original theory. Furthermore, the dual action is factorised into a propagating sector of massive gauge invariant variables and a sector with gauge variant variables defining a pure topological field theory. Combining results obtained within the Lagrangian and Hamiltonian formulations, a new completed structure for a gauge invariant dual factorisation of TMGT is thus achieved.
