description: Following the simple observation that the interconnection of a set of quantum optical input-output devices can be specified using structural mode VHSIC Hardware Description Language (VHDL), we demonstrate a computer-aided schematic capture workflow for modeling and simulating multi-component photonic circuits. We describe an algorithm for parsing circuit descriptions to derive quantum equations of motion, illustrate our approach using simple examples based on linear and cavity-nonlinear optical components, and demonstrate a computational approach to hierarchical model reduction.

An MDL framework for sparse coding and dictionary learning

description: The power of sparse signal modeling with learned over-complete dictionaries has been demonstrated in a variety of applications and fields, from signal processing to statistical inference and machine learning. However, the statistical properties of these models, such as under-fitting or over-fitting given sets of data, are still not well characterized in the literature. As a result, the success of sparse modeling depends on hand-tuning critical parameters for each data and application. This work aims at addressing this by providing a practical and objective characterization of sparse models by means of the Minimum Description Length (MDL) principle -- a well established information-theoretic approach to model selection in statistical inference. The resulting framework derives a family of efficient sparse coding and dictionary learning algorithms which, by virtue of the MDL principle, are completely parameter free. Furthermore, such framework allows to incorporate additional prior information to existing models, such as Markovian dependencies, or to define completely new problem formulations, including in the matrix analysis area, in a natural way. These virtues will be demonstrated with parameter-free algorithms for the classic image denoising and classification problems, and for low-rank matrix recovery in video applications.

description: We study the quantum transitions of a central spin surrounded by a collective-spin environment. It is found that the influence of the environmental spins on the absorption spectrum of the central spin can be explained with the analog of the Franck-Condon (FC) effect in conventional electron-phonon interaction system. Here, the collective spins of the environment behave as the vibrational mode, which makes the electron to be transitioned mainly with the so-called "vertical transitions" in the conventional FC effect. The "vertical transition" for the central spin in the spin environment manifests as, the certain collective spin states of the environment is favored, which corresponds to the minimal change in the average of the total spin angular momentum.

We introduce an analytical theory that yields an explicit formula for the response of an ensemble of NV- spins to an oscillating magnetic field, such as in NMR applications. We measure a detection bandwidth of 1.6 MHz and a sensitivity of 4.6 nT/Hz^(1/2), unprecedented in a detector with this active volume and close to the photon shot noise limit of our experiment.

description: Vancouver's Expo 86 was quite a party. It lasted for six months. Guests came from around the world; the final attendance figure of more than 20 million well exceeded that forecast. Visitors could explore pavilions and displays from nine provinces and territories, 54 countries, and major corporate exhibitors like General Motors (GM) and Canadian Pacific (CP). They could also amuse themselves on the many midway rides or dine at one of numerous fast food establishments, including a floating restaurant on False Creek nicknamed the "McBarge. When the decorations and the temporary pavilions came down, however, something very valuable remained -- over 200 acres of prime waterfront land. Now called Pacific Place, this tract of land is touted as one of the largest urban renewal projects in North America. The high-rise residential and commercial development under way here will greatly affect Vancouver's city form.

description: Fingerprint recognition is one of most popular and accuracy Biometric technologies. Nowadays, it is used in many real applications. However, recognizing fingerprints in poor quality images is still a very complex problem. In recent years, many algorithms, models...are given to improve the accuracy of recognition system. This paper discusses on the standardized fingerprint model which is used to synthesize the template of fingerprints. In this model, after pre-processing step, we find the transformation between templates, adjust parameters, synthesize fingerprint, and reduce noises. Then, we use the final fingerprint to match with others in FVC2004 fingerprint database (DB4) to show the capability of the model.

description: We present the growing mode solutions of cosmological perturbations to the second order in the matter dominated era. We also present several gauge-invariant combinations of perturbation variables to the second order in most general fluid context. Based on the solutions we study the Newtonian correspondence of relativistic perturbations to the second order. In addition to the previously known exact relativistic/Newtonian correspondence of density and velocity perturbations to the second order in the comoving gauge, here we show that in the sub-horizon limit we have the correspondences for density, velocity and potential perturbations in the zero-shear gauge and in the uniform-expansion gauge to the second order. Density perturbation in the uniform curvature gauge also shows the correspondence to the second order in the sub-horizon scale. We also identify the relativistic gravitational potential which shows exact correspondence to the Newtonian one to the second order.

description: Alexander Calhoun was the first public librarian in Calgary and the province of Alberta. He was born in Fenelon Falls, Ontario, in 1879 and attended Queen's University from 1898 to 1902 where he studied classics. After a short career as a teacher in Fort William (Thunder Bay). Calhoun became interested in the library profession in 1910. In February 1911, Calhoun moved to Calgary to begin work as the chief librarian of the new Carnegie funded public library which was still under construction. This study examines Calhoun's experience as the founding director of the Calgary Public Library, a position he held from 1911 to 1945. It also deals with other aspects of Calhoun's public life during a period of radical change as the economic boom of the early twentieth-century was followed by World War I. the Great Depression and World War IL

description: We consider a set of scalar fields, consisting of a single flat direction and one or several non-flat directions. We take our cue from the MSSM, considering separately D-flat and F-flat directions, but our results apply to any supersymmetric scenario containing flat directions. We study the field fluctuations during pure de Sitter Inflation, following the evolution of the infrared modes by numerically solving the appropriate Langevin equations. We demonstrate that for the Standard Model U(1), SU(2) or SU(3) gauge couplings, as well as for large enough Yukawa couplings, the fluctuations along the non-flat directions effectively block the fluctuations along the flat directions. The usual expected behaviour \propto N, with N the number of efolds, may be strongly violated, depending on the coupling strengths. As a consequence, those cosmological considerations, which are derived assuming that during inflation flat directions fluctuate freely, should be revised.

description: The deadly virus COVID-19 has affected not only the health of people but also the food value chain sector. The experience of the locked down period to curtail the spread of the virus was unexpected. It is therefore important to understand how small-scale farmers survived the period. This study examined the strategies employed by small-scale farmers in Osun State to adapt to the challenges resulting from COVID-19 lock down. Specifically, the study itemized types of crops grown by small-scale farmers, assessed the forms of challenges they faced during the COVID-19 pandemic, examined the perceived effects of these challenges on small-scale farming activities, and investigated the adaptation strategies employed by small-scale farmers during this time. Six communities in the local government were selected at random and a total of one hundred and twenty farmers from the communities were interviewed. A questionnaire was designed to collect the primary data. The data was analysed using descriptive statistics and the chi-square tools. Results showed that COVID-19 lock down period led to poor health status (mean=2.87), less transport available to convey farm produce (mean=2.70), and high cost with little/no access to farm inputs such as fertilizer, chemicals and seeds/seedlings (mean=2.62). The foremost effects of these challenges on small scale farming activities were poor marketing of agricultural produce (mean=4.52), decrease in farmers’ income (mean=4.51), and labour shortage (mean=4.39). The leading adaptation strategies employed by the farmers were planting of available grains instead of seeds (mean=2.85), reduced food consumption (mean=2.83), and the use of family labour (mean=2.80). The regression analysis showed that education (β=0.151), marital status (β =1.173), non-farm income (β=-6.790), and years of experience (β=-0.032) were significant (at p<0.05) factors influencing the adaptation strategies employed by the farmers. To effectively reduce the adverse effects of unexpected lockdowns on farmers in the future, it is recommended that outlets for necessary agricultural inputs should be made available in all farming communities.

description: Shape is one of the most important visual attributes to characterize objects, playing a important role in pattern recognition. There are various approaches to extract relevant information of a shape. An approach widely used in shape analysis is the complexity, and Fractal Dimension and Multi-Scale Fractal Dimension are both well-known methodologies to estimate it. This papers presents a comparative study between Fractal Dimension and Multi-Scale Fractal Dimension in a shape analysis context. Through experimental comparison using a shape database previously classified, both methods are compared. Different parameters configuration of each method are considered and a discussion about the results of each method is also presented.

description: Facial expression classification is a kind of image classification and it has received much attention, in recent years. There are many approaches to solve these problems with aiming to increase efficient classification. One of famous suggestions is described as first step, project image to different spaces; second step, in each of these spaces, images are classified into responsive class and the last step, combine the above classified results into the final result. The advantages of this approach are to reflect fulfill and multiform of image classified. In this paper, we use 2D-PCA and its variants to project the pattern or image into different spaces with different grouping strategies. Then we develop a model which combines many Neural Networks applied for the last step. This model evaluates the reliability of each space and gives the final classification conclusion. Our model links many Neural Networks together, so we call it Multi Artificial Neural Network (MANN). We apply our proposal model for 6 basic facial expressions on JAFFE database consisting 213 images posed by 10 Japanese female models.

Revisiting the "radial-drift barrier" of planet formation and its relevance in observed protoplanetary discs

description: Context. To form metre-sized pre-planetesimals in protoplanetary discs, growing grains have to decouple from the gas before they are accreted onto the central star during their phase of fast radial migration and thus overcome the so-called "radial-drift barrier" (often inaccurately referred to as the "metre-size barrier"). Aims. To predict the outcome of the radial motion of dust grains in protoplanetary discs whose surface density and temperature follow power-law profiles, with exponent p and q respectively. We investigate both the Epstein and the Stokes drag regimes which govern the motion of the dust. Methods. We analytically integrate the equations of motion obtained from perturbation analysis. We compare these results with those from direct numerical integration of the equations of motion. Then, using data from observed discs, we predict the fate of dust grains in real discs. Results. When a dust grain reaches the inner regions of the disc, the acceleration due to the increase of the pressure gradient is counterbalanced by the increase of the gas drag. We find that most grains in the Epstein (resp. the Stokes) regime survive their radial migration if-p+q+1/2 \leq0 (resp. if q\leq 2/3). The majority of observed discs satisfies both-p+q+ 1/2 \leq0 and q\leq 2/3: a large fraction of both their small and large grains remain in the disc, for them the radial drift barrier does not exist.

description: The possibility of strong coupling between a single molecule and surface plasmons is analyzed on the basis of a microscopic classical description. It is predicted that strong single molecule - plasmon coupling can happen for a silver nanoparticle only in the UV range where the real part of the dielectric function of silver approaches a value of -1. A critical view is taken on an interpretation of spectroscopic data of composite layers of dye molecules and a metal film in terms of single molecule-plasmon coupling in a Kretschman configuration in some recent publications. It is shown that experimental results interpreted as a mixed (hybrid) radiation do not reveal strong coupling and can be explained without any coupling effects.

description: The three-dimensional data-driven Allen Gene Expression Atlas of the adult mouse brain consists of numerized in-situ hybridization data for thousands of genes, co-registered to the Allen Reference Atlas. We propose quantitative criteria to rank genes as markers of a brain region, based on the localization of the gene expression and on its functional fitting to the shape of the region. These criteria lead to natural generalizations to sets of genes. We find sets of genes weighted with coefficients of both signs with almost perfect localization in all major regions of the left hemisphere of the brain, except the pallidum. Generalization of the fitting criterion with positivity constraint provides a lesser improvement of the markers, but requires sparser sets of genes.

description: The focus of this study was to analyze and map linkages among actors in the innovation system of cattle marketing in northeastern Nigeria. Specifically, linkages/interactions between actors and those of the innovation system network were determined. A structured questionnaire was used to collect data from 48 respondents and a Focus Group Discussion (FGD) session involving sixteen (16) participants each was conducted in three out of the four Adamawa Agricultural Development Project (AADP) zones of Adamawa State. Analytical tools used were descriptive statistics such as means, tables, and charts while the inferential statistical tool used was the Social Network Analysis (SNA). The results of the FGD interaction sessions revealed that the sixteen (16) actors had ninety-nine (99) ties in the network; these were classified into nine (9) key and seven (7) non-key actors with each group performing specific roles in the system. Furthermore, the result of the social network analysis revealed a network density of 0.83, indicating that 83% of all direct linkages were present. However, the network cohesion was 0.40, showing that only 40.0% of the connections were reciprocated, which implied that about 40% of the actors are not well connected. The result further revealed that both extension agents/Village Based Agents and the cattle dealers association had the highest degree and closeness centrality (73% and 6 links each), implying that they are the actors with more connections, closest to others and thus directly able to influence the decisions of other actors in the network; they can also be considered as the most important channels/agents for the diffusion of innovations in the system. The result of the network diagram revealed that there were strong, weak, unidirectional and reciprocal links among actors in the system. A strong link signifies high/dense interaction while a weak link signifies low/loose interaction among actors. Furthermore, unidirectional links indicate a one-way interaction/communication process while a reciprocal link signifies a feedback communication process. The study concluded that there is a great potential for increasing the interconnectedness, interaction, and collaboration between actors in the network. It was recommended that actors in public and private sectors should link, collaborate and interact more to produce a denser network for faster and more effective diffusion of technologies. Furthermore, the use of social media is strongly advocated to further strengthen linkage and networking among/between actors in the innovation system.

description: We exploit the SDSS galaxy groups catalogue of Yang et al. to study how the gas-phase metallicities of star-forming galaxies depend on environment. We find that satellite and central galaxies follow a qualitatively similar stellar mass (M_*) - gas-phase metallicity relation. Satellites, though, have higher gas-phase metallicities than equally massive centrals, and this difference increases with decreasing M_*. We also find that the gas-phase metallicity of satellites increases with halo mass at fixed stellar mass. This increment is more pronounced for less massive galaxies. We also show that low mass satellite galaxies have higher gas-phase metallicities than central galaxies of the same stellar metallicity. This difference becomes negligible for more massive galaxies of roughly solar metallicity. We demonstrate that the observed differences in gas-phase metallicity between centrals and satellites at fixed M_* are not a consequence of stellar mass stripping (advocated by Pasquali et al. in order to explain similar differences but in stellar metallicity), nor to the past star formation history of these galaxies as quantified by their surface mass density or gas mass fraction. Rather, we argue that these trends probably originate from a combination of three environmental effects: (i) strangulation, which prevents satellite galaxies from accreting new, low metallicity gas which would otherwise dilute their ISM, (ii) ram-pressure stripping of the outer gas disk, thereby inhibiting radial inflows of low-metallicity gas, and (iii) external pressure provided by the hot gas of the host halo which prevents metal-enriched outflows from escaping the galaxies.

description: We present a method to estimate Gibbs distributions with \textit{spatio-temporal} constraints on spike trains statistics. We apply this method to spike trains recorded from ganglion cells of the salamander retina, in response to natural movies. Our analysis, restricted to a few neurons, performs more accurately than pairwise synchronization models (Ising) or the 1-time step Markov models (\cite{marre-boustani-etal:09}) to describe the statistics of spatio-temporal spike patterns and emphasizes the role of higher order spatio-temporal interactions.

Von weiblicher Genitalbeschneidung betroffene Patientinnen in der Gynäkologie: Empfehlungen für eine kultursensible Betreuung und Prävention

description: GynäkologInnen in Deutschland sehen sich zunehmend mit beschnittenen Frauen und Mädchen konfrontiert. Entsprechenden Selbstregulierungen medizinischer Fachgesellschaften zur Behandlung beschnittener Frauen lassen sich zwar medizinische und berufsethische Orientierungen entnehmen, doch reichen diese für einen kultursensibel gestalteten ÄrztIn-PatientIn-Kontakt nicht aus. Daher werden auf der Basis kultureller und religiöser Hintergrundinformationen Handlungsempfehlungen für eine fachgerechte und kultursensible Betreuung betroffener Frauen und Mädchen vorgestellt. Aus ethischer Sicht ist weibliche Genitalbeschneidung (FGC) als nicht-einwilligungsfähiger Eingriff, der gravierend und u. U. irreversibel die körperliche und psychische Integrität und Gesundheit berührt, nicht vertretbar. Um weitere FGCs zu vermeiden, sollten GynäkologInnen „familiensystemisch“ vorgehen und zudem nach Geburt eines Mädchens die Zusammenarbeit mit der Pädiatrie anbahnen. Bei Vorliegen einer FGC sind die Folgen zu behandeln und eine Rekonstruktion des Genitals anzubieten. Nach der Geburt den FGC-Ausgangszustand wiederherzustellen, untersagt das Nicht-Schadens-Prinzip. Die vorliegende kultursensible Ergänzung einschlägiger Selbstregulierungen zeigt, dass nur konkrete Selbstregulierungsmaßnahmen zu Akzeptanz und Wirksamkeit führen können. Flankierend sollten das Gesundheitswesen, der Bildungssektor und die Sozial- und Entwicklungshilfepolitik gemeinsam mit den Sozial- und Kulturwissenschaften Konzepte zur Prävention von FGC entwickeln und erproben.

description: Unter dem Motto „Global denken – lokal handeln!“ wurde 1992 im Rahmen der UNO-Umweltkonferenz in Rio de Janeiro das Lokale-Agenda-21-Programm zur Verwirklichung nachhaltiger Entwicklungsziele beschlossen. Alle Kommunen sind seither dazu aufgerufen, neue Formen der Kooperation zwischen lokaler Verwaltung, Bürgerschaft und zivilgesellschaftlichen Organisationen anzuregen, mit dem Ziel, eine langfristige Nachhaltigkeitsstrategie für ihre Kommune zu entwickeln und dabei nachhaltige Entwicklungs- und Lernprozesse anzustoßen. Nach einer Boom-Periode zu Beginn der 2000er Jahre, in der es in zahlreichen deutschen Kommunen gelang, entsprechende Initiativen zu starten, zeigte sich bald, dass viele Städte und Gemeinden letztendlich überfordert waren, dieser ressourcenaufwendigen und komplexen Aufgabe dauerhaft gerecht zu werden. Dies wirft die Frage auf, welche Voraussetzungen gegeben sein müssen, um eine Lokale-Agenda-21-Strategie in eine Kommune langfristig umzusetzen. Wie am „Erfolgsfall“ der Stadt Heidelberg gezeigt werden kann, spielen hierfür neben günstigen strukturellen Gegebenheiten und institutionellen Vorkehrungen v. a. kooperationsorientierte Akteurskonstellationen und Interaktionsbeziehungen eine zentrale Rolle. Auf Basis halbstandardisierter Interviews mit zentralen Akteuren der Lokalen-Agenda-21 in Heidelberg lassen sich die komplexen Interaktionsbeziehungen zwischen Politik, Verwaltung und zivilgesellschaftlichen Akteuren nachzeichnen und Faktoren für einen langfristigen Agenda-Erfolg identifizieren.

description: The new 8.4m LBT adaptive secondary AO system, with its novel pyramid wavefront sensor, was used to produce very high Strehl (75% at 2.16 microns) near infrared narrowband (Br gamma: 2.16 microns and [FeII]: 1.64 microns) images of 47 young (~1 Myr) Orion Trapezium theta1 Ori cluster members. The inner ~41x53" of the cluster was imaged at spatial resolutions of ~0.050" (at 1.64 microns). A combination of high spatial resolution and high S/N yielded relative binary positions to ~0.5 mas accuracies. Including previous speckle data, we analyse a 15 year baseline of high-resolution observations of this cluster. We are now sensitive to relative proper motions of just ~0.3 mas/yr (0.6 km/s at 450 pc) this is a ~7x improvement in orbital velocity accuracy compared to previous efforts. We now detect clear orbital motions in the theta1 Ori B2/B3 system of 4.9+/-0.3 km/s and 7.2+/-0.8 km/s in the theta1 Ori A1/A2 system (with correlations of PA vs. time at >99% confidence). All five members of the theta1 Ori B system appear likely as a gravitationally bound "mini-cluster". The very lowest mass member of the theta1 Ori B system (B4; mass ~0.2 Msun) has, for the first time, a clearly detected motion (at 4.3+/-2.0 km/s; correlation=99.7%) w.r.t B1. However, B4 is most likely in an long-term unstable (non-hierarchical) orbit and may "soon" be ejected from this "mini-cluster". This "ejection" process could play a major role in the formation of low mass stars and brown dwarfs.

A Bayesian Approach to Forecasting Solar Cycles Using a Fokker-Planck Equation

description: A Bayesian method for forecasting solar cycles is presented. The approach combines a Fokker--Planck description of short--timescale (daily) fluctuations in sunspot number (\citeauthor{NobleEtAl2011}, 2011, \apj{} \textbf{732}, 5) with information from other sources, such as precursor and/or dynamo models. The forecasting is illustrated in application to two historical cycles (cycles 19 and 20), and then to the current solar cycle (cycle 24). The new method allows the prediction of quantiles, i.e. the probability that the sunspot number falls outside large or small bounds at a given future time. It also permits Monte Carlo simulations to identify the expected size and timing of the peak daily sunspot number, as well as the smoothed sunspot number for a cycle. These simulations show how the large variance in daily sunspot number determines the actual reliability of any forecast of the smoothed maximum of a cycle. For cycle 24 we forecast a maximum daily sunspot number of $166\pm 24$, to occur in March 2013, and a maximum value of the smoothed sunspot number of $66\pm5$, indicating a very small solar cycle.
