description: Toward an attempt to limit the global warming to 2 °C, there has been an increasing emphasis on devising suitable policies and practices for entrapment and storage of atmospheric CO2 to mitigate the detrimental effects of climatic change. Agriculture being a predominant global land use, C sequestration under different agro-ecosystems through appropriate management practices is an important option to combat the anthropogenic climate change. Conservation tillage along with residue management, stubble retention, mulching, organic farming and integrated nutrient management not only facilitates soil C storage but also improves soil health. Change in land-uses and cropping system also impart notable effects on soil C turnover. Biochar application is found effective in augmenting soil C stock and improving soil aggregation. Bioenergy plantations are also effective in sequestering C. Simulation models and remote sensing are innovative tools for predicting and mapping soil C status and identifying site-specific strategic policies to minimize the risk of land degradation and to maintain environmental sustainability. Therefore, the aim of this review is to disseminate ideas regarding current C status, identify researchable priorities and to deliberate pros and cons of agricultural management practices for better implementation of soil C sequestration strategies for mitigating the consequences of climate change.

description: We study the clustering of a model cyanobacterium \textit{Synechocystis} into microcolonies. The bacteria are allowed to diffuse onto surfaces of different hardness, and interact with the others by aggregation and detachment. We find that soft surfaces give rise to more microcolonies than hard ones. This effect is related to the amount of heterogeneity of bacteria's dynamics as given by the proportion of motile cells. A kinetic model that emphasizes specific interactions between cells, complemented by extensive numerical simulations considering various amounts of motility, describes the experimental results adequately. The high proportion of motile cells enhances dispersion rather than aggregation.

description: We expand a set of notions recently introduced providing the general setting for a universal representation of the quantum structure on which quantum information stands. The dynamical evolution process associated with generic quantum information manipulation is based on the (re)coupling theory of SU(2) angular momenta. Such scheme automatically incorporates all the essential features that make quantum information encoding much more efficient than classical: it is fully discrete; it deals with inherently entangled states, naturally endowed with a tensor product structure; it allows for generic encoding patterns. The model proposed can be thought of as the non-Boolean generalization of the quantum circuit model, with unitary gates expressed in terms of 3nj coefficients connecting inequivalent binary coupling schemes of n+1 angular momentum variables, as well as Wigner rotations in the eigenspace of the total angular momentum. A crucial role is played by elementary j-gates (6j symbols) which satisfy algebraic identities that make the structure of the model similar to "state sum models", employed in discretizing Topological Quantum Field Theories and quantum gravity. The spin network simulator can thus be viewed also as a Combinatorial QFT model for computation. The semiclassical limit (large j's) is discussed.

The role of relatedness in physical activity motivation, behaviour, and affective experiences : a self-determination theory perspective
Creators: name: McDonough, Meghan Heather
Publisher: name: University of British Columbia
Year: 2010

description: Self-Determination Theory (Deci & Ryan, 1985, 1991) suggests that meeting needs for autonomy, competence, and relatedness will affect the type of motivation (from amotivation to intrinsic motivation) experienced, along with cognitive, affective, and behavioural outcomes. Although relatedness should play an important role in motivation, limited research has examined the role of social constructs in this process. This project investigated antecedents and outcomes of relatedness and explored whether learning structure interventions facilitate relatedness and self-determination among adult dragon boaters. These aims were addressed in two studies. The first study involved a passive observation of 558 dragon boaters aged 19-83. Friendship quality, peer acceptance, social support, and age predicted relatedness. Autonomy, competence, relatedness, age, and gender significantly predicted self-determined motivation. Age and gender did not moderate these relationships. Self-determined motivation partially mediated the relationship between psychological needs (autonomy, competence, and relatedness) and positive and negative affect, while competence alone predicted physical self-worth, and physical activity. The second study was an 8-week intervention involving 210 paddlers from 12 dragon boat teams. Teams were randomly assigned to a cooperative or an individualistic learning intervention, and coaches were trained to conduct the intervention with their teams. Paddlers completed questionnaires at the beginning and end of the intervention period. Peer acceptance and psychological need fulfillment increased over the course of the 8 weeks similarly in both conditions. The only intervention effect was that autonomy was facilitated by the individualistic intervention. While expectations that the cooperative intervention would enhance social relationships and relatedness were not supported, mixed effects modeling analyses demonstrated a substantial within-team clustering effect, and found that changes in relatedness perceptions predicted changes in self-determined motivation. A replication of the mediator model test in Study 1 confirmed the role of self-determination as a partial mediator. Together these studies demonstrate the importance of relatedness in adult activity motivation, link social relationship constructs to relatedness and self-determination theory, and provide evidence that within-team clustering on social and motivational variables should be considered in research with in tact teams.

description: The Gutenberg-Richter (GR) and the Omori-Utsu (OU) law describe the earthquakes' energy release and temporal clustering and are thus of great importance for seismic hazard assessment. 
Motivated by experimental results, which indicate stress-dependent parameters, we consider a combined global data set of 127 main shock-aftershock sequences and perform a systematic study of the relationship between main shock-induced stress changes and associated seismicity patterns. 
For this purpose, we calculate space-dependent Coulomb Stress (& UDelta;CFS) and alternative receiver-independent stress metrics in the surrounding of the main shocks. Our results indicate a clear positive correlation between the GR b-value and the induced stress, contrasting expectations from laboratory experiments and suggesting a crucial role of structural heterogeneity and strength variations. 
Furthermore, we demonstrate that the aftershock productivity increases nonlinearly with stress, while the OU parameters c and p systematically decrease for increasing stress changes. Our partly unexpected findings can have an important impact on future estimations of the aftershock hazard.

description: The obscuration of a celestial body that covers another one in the background will be called a ``hierarchical eclipse''. The most obvious case is that a star or a planet will be hidden from sight by the moon during a lunar eclipse. Four objects of the solar system will line up then. We investigate this phenomenon with respect to the region of visibility and periodicity. There exists a parallax field constraining the chances for observation. A historic account from the Middle Ages is preserved that we analyse from different viewing angles. Furthermore, we provide a list of events from 0 to 4000 AD. From this, it is apparent that Jupiter is most often involved in such spectacles because its orbit inclination is small. High-inclination orbits reduce the probability to have a coincidence of an occultation of that object with a lunar eclipse.

Vestibular contributions to target-directed reaching movements
Creators: name: Brunke, Kirstin Marie
Publisher: name: University of British Columbia
Year: 2010

description: Through the use of galvanic vestibular stimulation (GVS), vestibular input has been implicated in the online control of goal-directed actions. Deviations of hand trajectory towards the anode electrode have been observed when stimulation is delivered during movement (Bresciani et al., 2002a; Bresciani et al., 2002b; Mars et al., 2003). The purpose of this experiment was to investigate the role of vestibular information in the planning and execution of target-directed reaching movements. Ten participants sat in a chair fixed to a rotating platform and pointed to an illuminated target when an auditory tone sounded. On all trials, participants were moved from an initial reclined position to a final upright posture and vision of the scene was removed at the auditory tone. Target position could either be cued or uncued. On stimulation trials, a 2 mA, 1000 ms pulse of bipolar, binaural GVS was delivered at the start of the reaction time (RT) interval. Pointing movements were analyzed at the start of the movement, the time of target plane acquisition, and the trial end. Neither GVS nor cue type had an influence on initial pointing direction. At the target plane, anode left trajectories were significantly above and to the left of the no GVS and the anode right trajectories. By trial end, however, clear lateral deviations were present with anode left and anode right trajectories significantly to the left and to the right of the no GVS condition, respectively. These findings suggest that GVS may have little impact on action planning when there is a high degree of whole-body stability. On the other hand, once sufficient time has passed for online control processes to mediate the ongoing action, and a movement transition is imminent, there is an increased weighting of vestibular input.
B Star Rotational Velocities in h and chi Persei: A Probe of Initial Conditions During the Star-Formation Process

description: Projected rotational velocities have been measured for 216 B0--B9 stars in the rich, dense h and chi Persei double cluster, and compared with the distribution of rotational velocities for a sample of field stars having comparable ages and masses. For stars that are relatively little evolved from their initial locations on the Zero Age Main Sequence (3-5 solar masses) the mean vsini measured for the h and chi Per sample is slightly more than 2 times larger than the mean determined for field stars of comparable mass, and the cluster and field vsini distributions differ with a high degree of significance. For somewhat more evolved stars with masses in the range 5-9 solar masses, the mean vsini in h and chi Per is 1.5 times that of the field; the vsini distributions differ as well, but with a lower degree of statistical significance. For stars that have evolved significantly from the ZAMS (those with masses in the range 9-15 solar masses), the cluster and field star means and distributions are only slightly different. We argue that both the higher rotation rates and the pattern of rotation speeds as a function of mass that differentiate main sequence B stars in h and chi Per from their field analogs were likely imprinted during the star formation process. We speculate that these differences may reflect the effects of the higher accretion rates that theory suggests are characteristic of regions that give birth to dense clusters, namely: (a) higher initial rotation speeds; (b) higher initial radii along the stellar birthline, resulting in greater spinup between the birthline and the ZAMS; and (c) a more pronounced maximum in the birthline radius-mass relationship that results in differentially greater spinup for stars that become mid- to late- B stars on the ZAMS.

description: Epitaxial films evolve on time and length scales that are inaccessible to atomistic computer simulation methods like molecular dynamics (MD). To numerically predict properties for such systems, a common strategy is to employ kinetic Monte Carlo (KMC) simulations, for which one needs to know the transition rates of the involved elementary steps. The main challenge is thus to formulate a consistent model for the set of transition rates and to determine its parameters. Here we revisit a well-studied model system, the epitaxial film growth of the fullerene C$_{60}$ on an ordered C$_{60}$ substrate(111). We implement a systematic multiscale approach in which we determine transition rates through MD simulations of specifically designed initial configurations. These rates follow Arrhenius' law, from which we extract energy barriers and attempt rates. We discuss the issue of detailed balance for the resulting rates. Finally, we study the morphology of subatomic and multilayer film growth and compare simulation results to experiments. Our model enables further studies on multi-layer growth processes of C$_{60}$ on other substrates.

description: The importance of agricultural technology in enhancing production and productivity can be realized when yield increasing technologies are widely been used and diffused. Standing from this logical ground, this paper aimed at identifying the determinants of agricultural technology adoption decision and examining the impact of adoption on farm income. Cross sectional data was collected through semi-structured questionnaire administered on 270 randomly selected smallholder farmers. Probit and Ordinary Least Square (OLS) regression models were employed. Consistent with the findings of previous studies, regression results showed that agricultural technology adoption decision of farm households has been determined by irrigation use, land ownership right security, credit access, distance to the nearest market, plot distance from the home stead, off-farm participation and tropical livestock unit. The regression result also revealed that agricultural technology adoption has a positive and significant effect on farm income by which adopters are better-offs than non-adopters.

description: For years, cannabis has been largely used for its mind-altering properties. However, the discovery of its medicinal and therapeutic attributes has led to increased medicinal use. With recent legalization of cannabis in Canada, there is an evolving proliferation of the commercial availability of cannabis-containing products, and changes to patterns of use amongst adults are anticipated. Research into the potential harmful effects from increased use due to legalization have begun in humans; however, to our knowledge, investigations into the environmental occurrence and outcomes in fish and wildlife have been largely overlooked. Increasingly potent cannabis strains are also entering both commercial and medicinal sectors thus adding to the potential risk that this product poses to the environment. Indeed, emerging evidence reveals that current wastewater treatment has limited ability to remove bioactive components of cannabis thus allowing their entry into aquatic ecosystems Furthermore, there is very little known regarding the effects, mechanisms and impacts of cannabis exposure in exposed biota, and is currently limited to a few lab-based and field-based studies in a handful of fish species (e.g. zebrafish). This review will discuss the therapeutic uses of cannabis and its constituents, as well as examine its environmental fate and potential to affect aquatic ecosystems in Canada.

description: Traditional data-driven deep learning models often struggle with high training costs, error accumulation, and poor generalizability in complex physical processes. Physics-informed deep learning (PiDL) addresses these challenges by incorporating physical principles into the model. Most PiDL approaches regularize training by embedding governing equations into the loss function, yet this depends heavily on extensive hyperparameter tuning to weigh each loss term. To this end, we propose to leverage physics prior knowledge by ``baking'' the discretized governing equations into the neural network architecture via the connection between the partial differential equations (PDE) operators and network structures, resulting in a PDE-preserved neural network (PPNN). This method, embedding discretized PDEs through convolutional residual networks in a multi-resolution setting, largely improves the generalizability and long-term prediction accuracy, outperforming conventional black-box models. The effectiveness and merit of the proposed methods have been demonstrated across various spatiotemporal dynamical systems governed by spatiotemporal PDEs, including reaction-diffusion, Burgers', and Navier-Stokes equations.

description: We propose a new method to solve the Killing spinor equations of eleven-dimensional supergravity based on a description of spinors in terms of forms and on the Spin(1,10) gauge symmetry of the supercovariant derivative. We give the canonical form of Killing spinors for N=2 backgrounds provided that one of the spinors represents the orbit of Spin(1,10) with stability subgroup SU(5). We directly solve the Killing spinor equations of N=1 and some N=2, N=3 and N=4 backgrounds. In the N=2 case, we investigate backgrounds with SU(5) and SU(4) invariant Killing spinors and compute the associated spacetime forms. We find that N=2 backgrounds with SU(5) invariant Killing spinors admit a timelike Killing vector and that the space transverse to the orbits of this vector field is a Hermitian manifold with an SU(5)-structure. Furthermore, N=2 backgrounds with SU(4) invariant Killing spinors admit two Killing vectors, one timelike and one spacelike. The space transverse to the orbits of the former is an almost Hermitian manifold with an SU(4)-structure and the latter leaves the almost complex structure invariant. We explore the canonical form of Killing spinors for backgrounds with extended, N>2, supersymmetry. We investigate a class of N=3 and N=4 backgrounds with SU(4) invariant spinors. We find that in both cases the space transverse to a timelike vector field is a Hermitian manifold equipped with an SU(4)-structure and admits two holomorphic Killing vector fields. We also present an application to M-theory Calabi-Yau compactifications with fluxes to one-dimension.

description: We analyze a sample of 12 HST-selected edge-on protoplanetary disks for which the vertical extent of the emission layers can be constrained directly. We present ALMA high angular resolution continuum images (0.1arcsec) of these disks at two wavelengths, 0.89mm and 2.06mm (respectively ALMA bands 7 and 4), supplemented with archival band 6 data (1.33mm) where available. For most sources, the millimeter continuum emission is more compact than the scattered light, both in the vertical and radial directions. Six sources are resolved along their minor axis in at least one millimeter band, providing direct information on the vertical distribution of the millimeter grains. For the second largest disk of the sample, the significant difference in vertical extent between band 7 and band 4 suggests efficient size-selective vertical settling of large grains. Furthermore, the only Class I object in our sample shows evidence of flaring in the millimeter. Along the major axis, all disks are well resolved. Four of them are larger in band 7 than in band 4 in the radial direction, and three have a similar radial extent in all bands. For all disks, we also derive the millimeter brightness temperature and spectral index maps. We find that the disks are likely optically thick and that the dust emission reveals low brightness temperatures in most cases (<10K). The integrated spectral indices are similar to those of disks at lower inclination. The comparison of a generic radiative transfer disk model with our data shows that at least 3 disks are consistent with a small millimeter dust scale height, of a few au (measured at r=100au). This is in contrast with the more classical value of h_g\sim10au derived from scattered light images and from gas line measurements. These results confirm, by direct observations, that large (millimeter) grains are subject to significant vertical settling in protoplanetary disks.

description: We study a joint facility location and cost planning problem in a competitive market under random utility maximization (RUM) models. The objective is to locate new facilities and make decisions on the costs (or budgets) to spend on the new facilities, aiming to maximize an expected captured customer demand, assuming that customers choose a facility among all available facilities according to a RUM model. We examine two RUM frameworks in the discrete choice literature, namely, the additive and multiplicative RUM. While the former has been widely used in facility location problems, we are the first to explore the latter in the context. We numerically show that the two RUM frameworks can well approximate each other in the context of the cost optimization problem. In addition, we show that, under the additive RUM framework, the resultant cost optimization problem becomes highly non-convex and may have several local optima. In contrast, the use of the multiplicative RUM brings several advantages to the competitive facility location problem. For instance, the cost optimization problem under the multiplicative RUM can be solved efficiently by a general convex optimization solver or can be reformulated as a conic quadratic program and handled by a conic solver available in some off-the-shelf solvers such as CPLEX or GUROBI. Furthermore, we consider a joint location and cost optimization problem under the multiplicative RUM and propose three approaches to solve the problem, namely, an equivalent conic reformulation, a multi-cut outer-approximation algorithm, and a local search heuristic. We provide numerical experiments based on synthetic instances of various sizes to evaluate the performances of the proposed algorithms in solving the cost optimization, and the joint location and cost optimization problems.

We apply the dual projection technique to uncover some properties of the noncommutative Maxwell-Chern-Simons theory up to first-order in the noncommutative parameter. A duality between this theory and a model similar to the ordinary self-dual model is estabilished. The correspondence of the basic fields is obtained and the equivalence of algebras and equations of motion are directly verified. We also comment on previous results in this subject.

description: We study the role of recombination, as practiced by genetically-competent bacteria, in speeding up Darwinian evolution. This is done by adding a new process to a previously-studied Markov model of evolution on a smooth fitness landscape; this new process allows alleles to be exchanged with those in the surrounding medium. Our results, both numerical and analytic, indicate that for a wide range of intermediate population sizes, recombination dramatically speeds up the evolutionary advance.

description: This study empirically examines the impact of capital fight and its macroeconomic determinants on agricultural growth in Nigeria from 1970 -2013. Data generated were analyzed using Unit root test, co-integration test, regression analysis. The study result found negative and insignificant relationship(P>0.05) between total capital flight and agricultural growth; meaning that capital flight has no direct impact on agricultural growth or the impact on agricultural growth is shadowed by the other macroeconomic variables in the system. Also, the stock of gross external debt (EXD) variable showed positive and statistically significant relationship (P<0.05) with agricultural growth. The result shows that a unit change in EXD will bring about 24% change in the growth of agriculture provided other factors are kept constant. Political instability (POL) variable has negative and significant effect on agricultural growth in Nigeria. The study recommends that Nigeria’s judicious use of the income accruing from loans and Foreign Direct Investment (FDI) is paramount if Agricultural growth is to be enhanced. Furthermore, the overall peace, security of lives and property and guaranty of investment by the government is essential therefore; Government should take concerted step to improve security of life and property in the country.

The developing countries are more and more involved in this process. Creating groups is associated with changes in the direction of trade flows. The main objective of the study is to identify the agri-food trade direction of the South-South regional trade groupings (CACM, CAN, EAC, MERCOSUR) taking into account selected indicators of regional trade interdependence. The agri-food trade in the all tested groupings was increasingly directed towards the member states rather than tertiary countries. The differences amongh the groups are related to changes in the direction of trade. Specialization of trade direction strengthened in the CACM and CAN countries, remained unchanged for the EAC countries, and declined in MERCOSUR. / Synopsis. Charakterystyczną cechą współczesnych międzynarodowych relacji handlowych jest rosnąca liczba regionalnych porozumień handlowych. W procesie tym coraz częściej uczestniczą kraje tzw. globalnego Południa. Utworzenie ugrupowania wiąże się między innymi ze zmianą kierunku przepływów handlowych. Głównym celem opracowania jest identyfikacja kierunku handlu rolno-żywnościowego regionalnych ugrupowań handlowych relacji Południe-Południe (CACM, CAN, EAC, MERCOSUR) w świetle wybranych wskaźników regionalnych współzależności handlowych. W wyniku przeprowadzonej analizy stwierdzono, że handel rolno-żywnościowy we wszystkich badanych ugrupowaniach w większym stopniu ukierunkowany jest na kraje członkowskie niż na kraje trzecie. Różnice pomiędzy ugrupowaniami dotyczą zmian tego ukierunkowania. Specjalizacja kierunkowa umacniała się w przypadku CACM i CAN, pozostawała bez zmian dla krajów EAC, a zmniejszyła się dla MERCOSUR.

description: We present cosmological parameter constraints as estimated using the Bayesian BeyondPlanck (BP) analysis framework. This method supports seamless end-to-end error propagation from raw time-ordered data to final cosmological parameters. As a first demonstration of the method, we analyze time-ordered Planck LFI observations, combined with selected external data (WMAP 33-61GHz, Planck HFI DR4 353 and 857GHz, and Haslam 408MHz) in the form of pixelized maps which are used to break critical astrophysical degeneracies. Overall, all results are generally in good agreement with previously reported values from Planck 2018 and WMAP, with the largest relative difference for any parameter of about 1 sigma when considering only temperature multipoles between 29

description: The sector of cooperative banking in Europe has occupied an important position in the banking system for many years, though its role in individual countries differs. Despite the reduction of the number of cooperative banks between 2004-2011, the number of their outposts increased. In recent years, members and customers of cooperative banks have grown dynamically. The cooperative banks increased the quantity of engaged and possessed assets. In the years 2004-2011, the discussed banks doubled their deposits (to 3,9 bln euro) and granted more than two times the number of loans (worth about 4 bln euro). / Synopsis. Sektor bankowości spółdzielczej w Europie zajmuje ważną pozycję w systemie bankowym od wielu lat, choć jego rola w poszczególnych krajach jest zróżnicowana. Pomimo zmniejszenia liczby banków spółdzielczych w latach 2004-2011, liczba ich placówek wzrosła. W ostatnich latach dynamicznie przybyło członków i klientów banków spółdzielczych. Banki spółdzielcze zwiększyły ilość zatrudnionych i posiadanych aktywów. W latach 2004-2011 omawiane banki podwoiły swoje depozyty (do 3,9 bln euro) i udzieliły ponad dwukrotnie wyższych kredytów (o wartości 4,0 bln euro).

description: We consider model A dynamics for a heating quench from the disordered (confined) into the ordered (deconfined) phase of SU(3) lattice gauge theory. For $4 N_σ^3$ lattices the exponential growth factors of low-lying structure function modes are calculated. The linear theory of spinodal decompositions is compared with the data from an effective model and the Debye screening mass is estimated from the critical mode. Further, the quench leads to competing vacuum domains, which make the equilibration of the QCD vacuum after the heating non-trivial. We investigate the influence of such domains on the gluonic energy density.

description: Ces dernières années ont été marquées par la signature de nombreux accords de commerce préférentiel prévoyant une réduction des entraves aux échanges entre pays. Un bon nombre d’entre eux incluaient des dispositions relatives aux mesures non tarifaires. Ce travail de recherche examine si les exigences techniques figurant dans les accords entre pays du Nord et du Sud ont un impact sur le commerce international. Plus précisément, les auteurs analysent dans quelle mesure l’harmonisation des règlementations techniques crée ou renforce une structure d’échanges du type «centre-périphérie» potentiellement dommageable pour l’intégration des pays du Sud au sein de l’économie mondiale. Les résultats empiriques de l’étude confirment cette conjecture.

description: La certification, quoique difficile et coûteuse, pourrait être dans certains cas une opportunité pour les petits agriculteurs, mais qu’en est-il réellement ? A Madagascar, au milieu des années 2000, le standard privé GlobalGAP a émergé dans la filière litchi en raison d’une demande de litchis certifiés de la part des importateurs européens. Toutefois, après une courte période d’engouement, le nombre de producteurs a rapidement chuté suite au retrait des bailleurs. Nous exploitons cette « expérience naturelle » pour évaluer l’impact de la certification GlobalGAP sur les performances commerciales des producteurs de litchis certifiés. Bien que nos résultats suggèrent un effet moyen positif significatif sur les quantités commercialisées comme sur les prix reçus par les producteurs, nous montrons que cet impact n’est pas distribué de manière homogène dans la population des producteurs certifiés et que seul un petit nombre d’entre eux bénéficie véritablement des effets de la certification. Cette situation pourrait toutefois évoluer si la filière malgache se trouvait contrainte de prendre des mesures pour garantir la conformité de ses produits avec les réglementations européennes. Elle pourrait alors se segmenter entre exportateurs certifiés ayant accès au marché européen et exportateurs non certifiés cantonnés aux marchés moins exigeants.
Double Distribution of Dark Matter Halos with respect to Mass and Local Overdensity

description: We present a double distribution function of dark matter halos, with respect to both object mass and local over- (or under-) density. This analytical tool provides a statistical treatment of the properties of matter surrounding collapsed objects, and can be used to study environmental effects on hierarchical structure formation. The size of the "local environment" of a collapsed object is defined to depend on the mass of the object. The Press-Schechter mass function is recovered by integration of our double distribution over the density contrast. We also present a detailed treatment of the evolution of overdensities and underdensities in Einstein-deSitter and flat LCDM universes, according to the spherical evolution model. We explicitly distinguish between true and linearly extrapolated overdensities and provide conversion relations between the two quantities.
