description: Preference divergence is thought to contribute to reproductive isolation. Ecology can alter the way selection acts on female preferences, making them most likely to diverge when ecological conditions vary among populations. We present a novel mechanism for ecologically dependent sexual selection, termed ‘the ecological stage’ to highlight its ecological dependence. Our hypothesized mechanism emphasizes that males and females interact over mating in a specific ecological context, and different ecological conditions change the costs and benefits of mating interactions, selecting for different preferences in distinct environments and different male traits, especially when traits are condition dependent. We test key predictions of this mechanism in a sympatric three-spine stickleback species pair. We used a maternal half-sib split-clutch design for both species, mating females to attractive and unattractive males and raising progeny on alternate diets that mimic the specialized diets of the species in nature. We estimated the benefits of mate choice for an indicator trait (male nuptial colour) by measuring many fitness components across the lifetimes of both sons and daughters from these crosses. We analysed fitness data using a combination of aster and mixed models. We found that many benefits of mating with high-colour males depended on both species and diet. These results support the ecological stage hypothesis for stickleback. Finally, we discuss the potential role of this mechanism for other taxa and highlight its ability to enhance reproductive isolation as speciation proceeds, thus facilitating the evolution of strong reproductive isolation.This article is part of the theme issue ‘Towards the completion of speciation: the evolution of reproductive isolation beyond the first barriers'.

description: We report a detailed theoretical study of the bonding and conduction properties of an hydrogen molecule joining either platinum or palladium electrodes. We show that an atomic arrangement where the molecule is placed perpendicular to the electrodes is unstable for all distances between electrodes. In contrast, the configuration where the molecule bridges the electrodes is stable in a wide range of distances. In this last case the bonding state of the molecule does not hybridize with the leads and remains localized within the junction. As a result, this state does not transmit charge so that electronic transport is carried only through the anti-bonding state. This fact leads to conductances of 1 $G_0$ at most, where $G_0=2e^2/h$. We indeed find that G is equal to 0.9 and 0.6 $G_0$ for Pt and Pd contacts respectively.

description: We present Fe K$β$ X-ray emission (XES) and Fe K X-ray absorption spectra (XAS) of Iron(II)sulfide (FeS) and Iron(II)disulfide (FeS$_2$). While XES and XAS offer different discrimination capabilities for chemical speciation, depending on the valence states of the compounds probed, XES allows for using different excitation sources. The XES data was measured using polychromatic X-ray radiation with a full-cylinder von Hamos spectrometer being characterized by an energy window of up to 700 eV and a spectral resolving power of $E/ ΔE = 800$. The large energy window at a single position of the spectrometer components is made profit of to circumvent the instrumental sensitivity of wavelength-dispersive spectrometers to sample positioning. This results in a robust energy scale which is used to compare experimental data with ab initio valence-to-core calculations, which are carried out using the OCEAN package. To validate the reliability of the OCEAN package for the two sample systems, near edge X-ray absorption fine structure measurements of the Fe K absorption edge are compared to theory using the same input parameters as in the case of the X-ray emission calculations. Based on the example of iron sulfide compounds, the combination of XES experiments and OCEAN calculations allows unravelling the electronic structure of different transition metal sulfides and qualifying XES investigations for the speciation of different compounds.

description: In this paper we explore the clustering properties and the environment of the Extremely Red Objects (EROs; I-K>4mag) detected in a ~180arcmin^2 deep (Ks~20mag) Ks-band survey of a region within the Phoenix Deep Survey, an on-going multiwavelength program aiming to investigate the nature and the evolution of faint radio sources. Using our complete sample of 289 EROs brighter than Ks=20mag we estimate a statistically significant (~3.7sigma) angular correlation function signal with amplitude Aw=8.7^{+2.1}_{-1.7}x10^{-3} consistent with earlier work based on smaller samples. This amplitude suggests a clustering length in the range ro=12-17h^{-1}Mpc, implying that EROs trace regions of enhanced density. Using a novel method we further explore the association of EROs with galaxy overdensities by smoothing the K-band galaxy distribution using the matched filter algorithm of Postman et al. (1996) and then cross-correlating the resulting density maps with the ERO positions. Our analysis provides direct evidence that EROs are associated with overdensities at redshifts z>1. We also exploit the deep radio 1.4GHz data (limiting flux 60microJy) available to explore the association of EROs and faint radio sources and whether the two populations trace similar large scale structures. Cross-correlation of the two samples (after excluding 17EROs with radio counterparts) gives a 2sigma signal only for the sub-sample of high-z radio sources (z>0.6). Although the statistics are poor this suggests that it is the high-z radio sub-sample that traces similar structures with EROs.

Le modèle de prix hédonique a été utilisé pour déterminer les prix marginaux implicites des attributs du riz local et du riz importé. Les données aussi bien quantitatives que qualitatives ont été collectées auprès d’un échantillon de 233 ménages consommateurs de riz repartis dans deux départements du Bénin (Collines et Littoral). Il ressort des résultats que pour le riz importé, les prix marginaux implicites sont de 45,3FCFA pour l’absence de corps étrangers, 46,25FCFA pour la disponibilité toute l’année, 51,66 FCFA pour la blancheur, 16,21FCFA pour l’arôme et 14,11FCFA pour la cohésion des grains. Quant au riz local, les consommateurs sont disposés à payer marginal pour bénéficier des attributs tels que la cohésion (18,88 FCFA) et la forte capacité de gonflement (13,84FCFA). Pour les autres attributs tels que la disponibilité en période pré récolte, la disponibilité en période de récolte ou de post-récolte et le goût, les prix marginaux implicites sont négatifs pour le riz local : - 48,24 ; -39,94 et -51,56FCFA respectivement. Plusieurs efforts restent donc à faire pour changer cette tendance.

description: Crowd synchrony, which corresponds to the synchronization of different and independent oscillators that interact with each other via a common intermediate, is ubiquitous in many fields. Here, we experimentally demonstrate the effect of crowd synchrony, analogous to that of the Millennium Bridge, by resorting to coupled lasers. When the number of lasers is below a critical number, there is no synchronization, but after reaching the critical number, the lasers instantaneously synchronize. We show that the synchronization of the lasers as a function of their number follows a first-order-like transition, and that our experimental results are in good agreement with those predicted by theoretical models.

description: Studies affirm that developing countries will be hardest it by the dynamics of climate change given that they have to contend with extreme poverty levels and waning levels of economic growth. Climate variability will impact on water resources, land, forests and ecosystems, all of which will threaten livelihoods and food security. In developing countries the effects of climate change will manifest as increased and deeper exposure to vulnerabilities, with the previously attained development gains being compromised. Together these factors will impact on the achievement of the MDGs. Although Africa contributes negligibly to Greenhouse Gas (GHG) emissions, it will be worst affected due to its geographical location, its dependence on climate-sensitive resources and its overall inherent limitations financially, institutionally and human resource wise. Although most of Africa will feel the adversity that climate change will engender, certain African countries are at greater risk than others given their vulnerability and their subdued development credentials. We use a number of proxy variables as indicators of countries sliding further down the development stakes due to increased risk from climate change expounded as decreases in income or economic growth or increased expenditure on food that will siphon off development funds. The paper will look at the impact of climate change in developing countries and in Africa as a whole, with an analysis of why certain African countries will be worse off from the after-effects of climate change. Lastly, policy options will be briefly touched on.

description: The Eridanus galaxies follow the well-known radio-FIR correlation. Majority (70%) of these galaxies have their star formation rates below that of the Milky Way. The galaxies having a significant excess of radio emission are identified as low luminosity AGNs based on their radio morphologies obtained from the GMRT observations. There are no powerful AGNs (L{20cm} > 10^{23} W Hz^{-1}) in the group. The two most far-infrared and radio luminous galaxies in the group have optical and HI morphologies suggestive of recent tidal interactions. The Eridanus group also has two far-infrared luminous but radio-deficient galaxies. It is believed that these galaxies are observed within a few Myr of the onset of an intense star formation episode after being quiescent for at least a 100 Myr. The upper end of the radio luminosity distribution of the Eridanus galaxies (L_{20cm} ~ 10^{22} W Hz^{-1}) is consistent with that of the field galaxies, other groups, and late-type galaxies in nearby clusters.

description: Five-dimensional field theories compactified on an S^1/Z_2 orbifold naturally include local brane kinetic terms at the orbifold fixed points at the tree as well as the quantum level. We study the quantization of these theories before the Kaluza--Klein reduction and derive the relevant Ward and Slavnov-Taylor identities that result from the underlying gauge and Becchi-Rouet-Stora symmetries of the theory. With the help of these identities, we obtain a generalization of the equivalence theorem, where the known high-energy equivalence relation between the longitudinal Kaluza-Klein gauge modes and their respective would-be Goldstone bosons is extended to consistently include the energetically suppressed terms in the high-energy scatterings. Demanding perturbative unitarity, we compute upper limits on the number of the Kaluza-Klein modes. We find that these limits weakly depend on the size of the brane kinetic terms.

description: The production of biofuels and the establishment of a biofuels industry in South Africa have largely been hampered by the structure, procedures and requirements as set out in the Industrial Biofuel Strategy. This article sketches the industry by means of a game theoretic representation. A model is developed that represents the rational strategies of various role players in the industry with respect to investor decision making. In reality this did not occur and the article develops and documents a variable, σ, which in turn helps to represent the current state of affairs. The study explains why current investment decisions in the industry have been made and why certain role players remain indifferent towards any commitment.

We construct a set of cardinality continuum such that: all continuous images of the set into the Cantor cube are null-additive, it contains a homeomorphic copy of a set that is not null-additive, and it has the property $γ$, a strong combinatorial covering property. We also construct a nontrivial subset of the Cantor cube with the property $γ$ that is not null additive. Set-theoretic assumptions used in our constructions are far milder than used earlier by Galvin--Miller and Bartoszyński--Recław, to obtain sets with analogous properties. We also consider products of Sierpiński sets in the context of combinatorial covering properties.

Characterization of an atmospheric pressure ion lens for electrospray ionization sources in mass spectrometry
Creators: name: Manisali, Irina
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this project is to characterize the properties of an atmospheric pressure ion lens used to facilitate and improve the operation of electrospray ionization (ESI) sources for mass spectrometry (MS). This work is in part motivated by the inefficient transmission of ions from atmospheric pressure into vacuum, characteristic of current electrospray ion source designs. The first chapter of this thesis will be an introduction to the basic theory and the historical developments of ESI sources for MS from early designs to today's commercial geometries. The second chapter of this thesis summarizes previous research that has been done with respect to atmospheric pressure electrostatic devices for ESI sources, including work done in our laboratory. The objective of the present project is also described in more detail in this section. Descriptions of the instruments and their operation, as well as the experimental procedures used in this project are presented in the third chapter. The fourth chapter presents some of the results and it attempts to explain the observed trends with the help of simulations. The results show that the mechanism of the ion lens is not trivial. The effect 6f the ion lens is different for analytes of various charge states and is highly dependent on a number of instrumental and environmental parameters. The size and shape of the lens is also important. The ion lens was shown to stabilize the electrospray, as well as improve the signal-to-noise ratio (S/N) in some instances, while at other times it was difficult to observe any effect at all. Future work that may help optimize the operation of the ion lens is discussed in the final chapter.

description: We use the $1/N_c$ expansion of QCD to analyse the spectrum of positive parity resonances with strangeness $S = 0, -1, -2$ and -3 in the 2--3 GeV mass region, supposed to belong to the $[\textbf{56},4^+]$ multiplet. The mass operator is similar to that of $[\textbf{56},2^+]$, previously studied in the literature. The analysis of the latter is revisited. In the $[\textbf{56},4^+]$ multiplet we find that the spin-spin term brings the dominant contribution and that the spin-orbit term is entirely negligible in the hyperfine interaction, in agreement with constituent quark model results. More data are strongly desirable, especially in the strange sector in order to fully exploit the power of this approach. We discuss possibilities of extending the calculations to other excited baryons belonging to the N=2 or the N=4 band.

description: Limpets (Patella vulgata L.) are renowned for their powerful attachments to rocks on wave-swept seashores. Unlike adult barnacles and mussels, limpets do not adhere permanently; instead, they repeatedly transition between long-term adhesion and locomotive adhesion depending on the tide. Recent studies on the adhesive secretions (bio-adhesives) of marine invertebrates have expanded our knowledge on the composition and function of temporary and permanent bio-adhesives. In comparison, our understanding of the limpets' transitory adhesion remains limited. In this study, we demonstrate that suction is not the primary attachment mechanism in P. vulgata; rather, they secrete specialized pedal mucus for glue-like adhesion. Through combined transcriptomics and proteomics, we identified 171 protein sequences from the pedal mucus. Several of these proteins contain conserved domains found in temporary bio-adhesives from sea stars, sea urchins, marine flatworms and sea anemones. Many of these proteins share homology with fibrous gel-forming glycoproteins, including fibrillin, hemolectin and SCO-spondin. Moreover, proteins with potential protein and glycan degrading domains could have an immune defence role or assist degrading adhesive mucus to facilitate the transition from stationary to locomotive states. We also discovered glycosylation patterns unique to the pedal mucus, indicating that specific sugars may be involved in transitory adhesion. Our findings elucidate the mechanisms underlying P. vulgata adhesion and provide opportunities for future studies on bio-adhesives that form strong attachments and resist degradation until necessary for locomotion.

description: The production of biofuels in many countries is largely driven by the government strategy and incentives that are in place. In South Africa the first round of the development of such a draft strategy took place in 2005 while the official stance on biofuels was finalized in December of 2007. During the policy development process various governmental departments had strategic goals and targets that they all were required to achieve. The achievement of these strategic targets and goals is also risky and the various departments that have some form of involvement in the biofuels industry need to decide on how much risk they are willing to take. This article sketches the game that the various governmental departments played as well as the risks that they were faced with when writing the Industrial Biofuels Strategy. In establishing a Nash Equilibrium and when comparing this to the current state of affairs in the industry an investigation is launched as to what has caused the governmental department to divert so strongly from this position. A variable Z is defined and included in the model in order to explain the current state of affairs. The Z variable is also analyzed further in order to bring some form of structure to the debate on the government’s stance on the issue.

description: Global biofuel production has risen substantially in recent years, driven primarily by government support for biofuel industries. The stated motivations for these initiatives are numerous and have varied over time. Soybeans are the only field crop produced in sufficient quantities in KwaZulu-Natal (KZN) that the South African (SA) industrial biofuel strategy identifies as a potential biodiesel feedstock. Preliminary results from a mixed integer linear programming model support the notion of Funke et al. (2009), who contend that the incentives and commitments outlined by the industrial biofuel strategy are inadequate to both establish and sustain a domestic biodiesel industry.

description: We study the phase diagram of a one-dimensional extended Hubbard model with antiferromagnetic exchange interaction analytically and numerically. The bosonization and transfer-matrix renormalization group methods are used in the corresponding coupling regimes. At half-filling, the system is a Mott insulator with a finite spin excitation gap if the on-site Coulomb repulsion is fairly smaller than the antiferromagnetic exchange J. This Mott-insulator is characterized by the bond-charge-density-wave order or spontaneously dimerization. In the weak-coupling regime where the spin-charge separation holds approximately, the critical point separating the gapless and gapped spin liquid phases is U_c\sim J/2. However, as J increases, the spin-charge couplings become important and the critical point U_c is significantly suppressed and eventually tends to zero as J\to \infty. Away from half-filling, the charge gap completely collapses but the spin gap persists.

description: Byte-addressable persistent memory, such as Intel/Micron 3D XPoint, is an emerging technology that bridges the gap between volatile memory and persistent storage. Data in persistent memory survives crashes and restarts; however, it is challenging to ensure that this data is consistent after failures. Existing approaches incur significant performance costs to ensure crash consistency. This paper introduces Crafty, a new approach for ensuring consistency and atomicity on persistent memory operations using commodity hardware with existing hardware transactional memory (HTM) capabilities, while incurring low overhead. Crafty employs a novel technique called nondestructive undo logging that leverages commodity HTM to control persist ordering. Our evaluation shows that Crafty outperforms state-of-the-art prior work under low contention, and performs competitively under high contention.

description: Reliable data on private sector agricultural research and development is globally scarce, particularly in developing countries. In South Africa, it has been observed that research performance by the public sector via the Agricultural Research Council has declined in recent years and consequently, the private sector has embarked on a much larger role in South Africa’s agriculture research than before. However, the extent of this engagement remains unknown as data quantifying private sector agricultural R&D is limited. This study identified 51 private firms that perform agriculture related research activities and attempts to gather primary data to determine the nature and extent of private R&D in South Africa. However due to the large number of non-responses, the study covers only 19% of these firms. Nevertheless, the study found that the participation of the private sector in agriculture research in the past decade has increased; in terms of research expenditure by more than 100% and number of research personnel by more than 50%. It emerged that the nature of research done by the private sector locally is mainly adaptive research - focused on testing imported technology to ensure registration and certification for use on the local market as opposed to developing ‘own’ innovations. The most influencing government policy initiatives in the participation of the private sector in South Africa’s agriculture R&D have been deregulation of agriculture markets and liberalization of agricultural trade, which have increased the spill-in of agriculture technologies to South Africa. The study recommends that, in order to ensure sustainability and efficiency of private sector research, collaboration between the public sector and private sector as well as international organizations will be crucial.

description: The propensity for synchronization is studied in a complex network of asymmetrically coupled units, where the asymmetry in a given link is determined by the relative age of the involved nodes. In growing scale-free networks synchronization is enhanced when couplings from older to younger nodes are dominant. We describe the requirements for such an effect in a more general context and compare with the situations in non growing random networks with and without a degree ordering.

On the super replication price of unbounded claims

description: In an incomplete market the price of a claim f in general cannot be uniquely identified by no arbitrage arguments. However, the ``classical'' super replication price is a sensible indicator of the (maximum selling) value of the claim. When f satisfies certain pointwise conditions (e.g., f is bounded from below), the super replication price is equal to sup_QE_Q[f], where Q varies on the whole set of pricing measures. Unfortunately, this price is often too high: a typical situation is here discussed in the examples. We thus define the less expensive weak super replication price and we relax the requirements on f by asking just for ``enough'' integrability conditions. By building up a proper duality theory, we show its economic meaning and its relation with the investor's preferences. Indeed, it turns out that the weak super replication price of f coincides with sup_{Q\in M_Φ}E_Q[f], where M_Φ is the class of pricing measures with finite generalized entropy (i.e., E[Φ(\frac{dQ}{dP})]

description: The paper aims to investigate the economies of scale of Water Users’ Associations (WUA) in Tunisia. During the last years there has been a lot of discussion in Tunisia about the optimal size of WUAs, which allows more efficient management of the water resources at the local level. In this work we propose to see if the size of the WUA in the governorate of Nabeul (Central-Eastern part of Tunisia) would have to increase or decrease in order to maximize their efficiency. Apart from this qualification we also quantify the scale efficiency and scale elasticity of the WUA using Data Envelopment Analysis (DEA) models. The results show that the output space (volume of water distributed and number of ha managed and irrigated) of the WUA that attain a high level of scale efficiency is highly diverse, indicating that the number of ha irrigated and the volume of water distributed are not explaining the differences in the scale efficiency of WUA. The calculation of scale elasticity of the WUA shows that 41% of the WUA are operating at decreasing returns to scale (DRS) while 16% and 43% operate at constant (CRS) and increasing (IRS) returns to scale, respectively. The scale orientation was found to be depending on the output density rather than on the output size. Thus, WUA located in more irrigation-intensified areas were found to be IRS oriented. WUA operating at CRS were found to have the minimum costs, which is in line with the theoretical predictions that suggest that the average productivity is maximized when the scale efficiency is equal to 1.

description: In this paper, we introduce a novel suspect-and-investigate framework, which can be easily embedded in a drone for automated parking violation detection (PVD). Our proposed framework consists of: 1) SwiftFlow, an efficient and accurate convolutional neural network (CNN) for unsupervised optical flow estimation; 2) Flow-RCNN, a flow-guided CNN for car detection and classification; and 3) an illegally parked car (IPC) candidate investigation module developed based on visual SLAM. The proposed framework was successfully embedded in a drone from ATG Robotics. The experimental results demonstrate that, firstly, our proposed SwiftFlow outperforms all other state-of-the-art unsupervised optical flow estimation approaches in terms of both speed and accuracy; secondly, IPC candidates can be effectively and efficiently detected by our proposed Flow-RCNN, with a better performance than our baseline network, Faster-RCNN; finally, the actual IPCs can be successfully verified by our investigation module after drone re-localization.

description: This paper approaches the soil and water management (SWMGT) adoption estimation from the perspective of the modern evaluation theory. As a result, the analytical procedure adopted for the study follows the Average Treatment Effect (ATE) estimation framework. The data gathered for the analysis are part of the baseline data collected from a sample of 572 households in 20 villages in Maradi (Niger Republic) and katsina (Nigeria). Results show that about 45 percent of the respondents have adopted the soil and water management (SWMGT) practices, out of 398 (70%) households that had knowledge or were aware of the SWMGT options. The joint exposure and adoption rates from three different models have been estimated at 39%. Results for joint exposure and adoption (within the SWMGT exposed sub-population) rate are also similar for the three models (59%) with similar range of 95% confidence interval (between 52% and 65%). With the intervention of the SSACP through the 2 IAR4D, it is expected that the adoption rate could be increased by at least 14% if an effective awareness of these SWMGT practices through the Innovation Platform system is undertaken. Key words: Adoption, Exposure, Average treatment Effect, Innovation Platform, Integrated Agricultural Research for Development.
