Culex habilitator

description: Culex (Culex) habilitator Dyar en Knab, 1906
Although Van der Kuyp (1948, 1949, 1954) reported Cx. habilitator from land crab holes on Sint Maarten (Rolandus Channel and Lower Princess Quarter) often together with De. magnus, we did not find any. The identification of this species is problematic as adults look very similar to Cx. bahamensis, whereas the larvae resemble Cx. nigripalpus. Despite the fact that Van der Kuyp collected both larvae and adults, and therefore identification should be easy, his description of the larvae does not agree with diagnostic characters described by Bram (1967). The larvae of Van der Kuyp have “anal gills, about as long as the segment, with blunt tips” and are pictured with a double apical tuft on the siphon; the gills should be short, pointed, and the tuft should be triple.This suggests that the larvae actually fit the description of Cx. nigripalpus, a species that is sometimes found in crab holes as well (Belkin et al., 1970). Van der Kuyp’s adults do however resemble the few available descriptions of Cx. habilitator (Dyar, 1928; Lane, 1953 [erroneously noted as “habilitador” [sic]]; Bram, 1967). The fact that Cx. habilitator is present on many of the Lesser Antillean islands (Belkin&Heinemann, 1975, 1976; Schaffner, 2003) suggests that this species may be present on the Dutch Leeward Islands too. To determine whether Van der Kuyp’s records really represent this species, a reanalysis of the original material stored in the Smithsonian Institution is needed (National Museum of Natural History, Washington D.C., USA – NMNH).

description: The crystal structures of two ansa-titanocene tri-fluoro-methane-sulfonate complexes bearing the Me2Si(C5Me4)2 ligand are reported, namely [di-methylbis-(η5-tetra-methyl-cyclo-penta-dien-yl)silane](tri-fluoro-methane-sulfonato-κ2O,O')titanium(III) toluene monosolvate, [Ti(CF3O3S)(C20H30Si)]·C7H8, 1, and chlorido-[di-methyl-bis-(η5-tetra-methyl-cyclo-penta-dien-yl)silane](tri-fluoro-methane-sulfonato-κO)titanium(IV), [Ti(CF3O3S)(C20H30Si)Cl], 2. Both complexes display a bent metallocene unit, the metal atom being coordinated in a distorted tetra-hedral geometry, with the tri-fluoro-methane-sulfonate anion acting as a bidentate or monodentate ligand in 1 and 2, respectively. In 1, weak π-π stacking inter-actions involving the toluene solvent mol-ecules [centroid-to-centroid distance = 3.9491 (11) Å] are observed.

description: A study was undertaken to compare the survival efficacy of two native, previously characterized bacterial biovars viz. Bacillus subtilis BCU5 and Pseudomonas fluorescens PCU17 with Bacillus subtilis strain MTCC1789 and Pseudomonas fluorescens strain MTCC4828, procured from Institute of Microbial Technology, Chandigarh, India in cumin rhizosphere and bulk soil. All the four bacterial types were made rifampicin resistant and the mutants were applied as inoculants at the dosage of 6 log, 7 log and 8 log colony forming units (cfu) g-1 dry soil weight in pots containing cumin seedlings. The cfu of rhizosphere and bulk soil of pots was observed per week for four weeks. The results show that the initial population decline is a common feature of bioinoculants. In rhizosphere and bulk soil, the native bacterial biovars survived better than their procured counterparts. The population of P. fluorescens strain MTCC4828r in rhizosphere soil declined faster and reached below detection limit whereas the P. fluorescens biovar PCUr rhizosphere final population dropped to 3.1 log, 2.9 log and 2.13 log cfu g-1 soil dry weight with 8 log, 7 log and 6 log cfu g-1 soil dry weight inoculum treatment, respectively. In contrast to P. fluorescens strain MTCC4828r, the population of B. subtilis strain MTCC1789r stabilized after some decline and was comparable with B. subtilis biovar BCU5 population. Study concludes that the inoculant population decline in soil was the result of lower microbial load carrying capacity of soil than the provided inoculum densities. Also, the native bacteria survived better than procured ones in rhizosphere soil.

Culex nigripalpus

description: Culex (Culex) nigripalpus Theobald, 1901
Culex nigripalpus has been recorded for the first time from the Dutch Leeward Islands in our survey at two localities on Sint Maarten (2 ♀, 1 ♂, Rolandus Channel, 18°01’53.9“ N, 63°02’17.7” W, April 20th, 2018; 1 ♀, Belvedere, 18°03’26.9“ N, 63°02’14.4” W, April 20th, 2018, next to an open drain and small pond).
When Van der Kuyp sampled the Rolandus Channel in the late 1940s, Cx. nigripalpus was not observed (Van der Kuyp, 1953, 1954), but Cx. habilitator was recorded at this locality. The larvae of that species look very similar to those of Cx. nigripalpus. Therefore, Cx. nigripalpus may have been present during Van der Kuyp’s inventory but was misidentified as Cx. habilitator.

description: Motivated by applications to Bayesian inference for statistical models with orthogonal matrix parameters, we present polar expansion, a general approach to Monte Carlo simulation from probability distributions on the Stiefel manifold. To bypass many of the well-established challenges of simulating from the distribution of a random orthogonal matrix Q, we construct a distribution for an unconstrained random matrix X such that QX, the orthogonal component of the polar decomposition of X, is equal in distribution to Q. The distribution of X is amenable to Markov chain Monte Carlo (MCMC) simulation using standard methods, and an approximation to the distribution of Q can be recovered from a Markov chain on the unconstrained space. When combined with modern MCMC software, polar expansion allows for routine and flexible posterior inference in models with orthogonal matrix parameters. We find that polar expansion with adaptive Hamiltonian Monte Carlo is an order of magnitude more efficient than competing MCMC approaches in a benchmark protein interaction network application. We also propose a new approach to Bayesian functional principal component analysis which we illustrate in a meteorological time series application.

Culex quinquefasciatus

description: Culex (Culex) quinquefasciatus Say, 1923
Culex quinquefasciatus is strongly associated with urbanization, as it prefers artificial containers and polluted groundwater as larval habitats (Belkin et al., 1970). The species had been already introduced into the New World from Africa before 1800 (Belkin, 1962). As expected, Cx. quinquefasciatus was present in urban habitats on all three islands. Because of the complexity of the Cx. pipiens complex, of which Cx. quinquefasciatus is a member, we did not delve deeper into the identification of this species on the Dutch Leeward Islands. All (sub)tropical populations from the New World have been considered to be Cx. quinquefasciatus although Culex pipiens s.s. was also introduced to the Americas (Harbach, 2012). The two lack clear morphological differences and interbreed within their non-native range (Cornel et al., 2012). Only a genetic study of the Caribbean populations can reveal their identity.

Culex bisulcatus

description: Culex (Culex) bisulcatus (Coquillett, 1906)
Culex bisulcatus was synonymized with Cx. americanus (NeveuLemaire, 1902) by Dyar (1928), but restored by Stone (1967) as a valid species. Berlin (1969a: 30–34) re-analyzed the material of Van der Kuyp and concluded that the material belongs to Cx. bisulcatus. Material from the Leeward Islands matches the topotypic material from Guadeloupe, except for the number of setae on the 9th tergite lobe of the male genitalia, which are more numerous on those of the Leeward Islands (Berlin, 1969a). Up to now, this taxonomic problem has not been addressed using modern genetic analysis. Due to a lack of genetic reference material, we were unable to address this problem in the current study. In this study, larvae of Cx. bisulcatus were only observed in bromeliads on Saba. The species was previously also recorded on Sint Eustatius and Sint Maarten (Van der Kuyp, 1948, 1949, 1953, 1954), but was not retrieved from these locations despite considerable efforts. There are two possible explanations for this. First, climatological conditions were suboptimal for this species during our visit. This may be an explanation for Sint Eustatius, where most of the sampled phytotelmata were dry in comparison to the summer when they may be filled with water. Second, the number of bromeliads was strongly reduced due to urbanization and recent hurricanes on Sint Maarten (Richardson et al., 2015), as we observed many bromeliads on fallen branches. Despite sampling dozens of bromeliads on Sint Peter Hill and the South Reward, the only remaining habitat on Sint Maarten, no larvae were found.

description: We propose the additive functional Cox model to flexibly quantify the association between functional covariates and time to event data. The model extends the linear functional proportional hazards model by allowing the association between the functional covariate and log hazard to vary nonlinearly in both the functional domain and the value of the functional covariate. Additionally, we introduce critical transformations of the functional covariate which address the weak model identifiability in areas of information sparsity and discuss their impact on interpretation and inference. We also introduce a novel estimation procedure that accounts for identifiability constraints directly during model fitting. Methods are applied to the National Health and Nutrition Examination Survey 2003–2006 accelerometry data and quantify new and interpretable circadian patterns of physical activity that are associated with all-cause mortality. We also introduce a simple and novel simulation framework for generating survival data with functional predictors which resemble the observed data. The accompanying inferential R software is fast, open source, and publicly available. Our data application and simulations are fully reproducible through the accompanying vignette.

description: Linear mixed-effects models play a fundamental role in statistical methodology. A variety of Markov chain Monte Carlo (MCMC) algorithms exist for fitting these models, but they are inefficient in massive data settings because every iteration of any such MCMC algorithm passes through the full data. Many divide-and-conquer methods have been proposed to solve this problem, but they lack theoretical guarantees, impose restrictive assumptions, or have complex computational algorithms. Our focus is one such method called the Wasserstein Posterior (WASP), which has become popular due to its optimal theoretical properties under general assumptions. Unfortunately, practical implementation of the WASP either requires solving a complex linear program or is limited to one-dimensional parameters. The former method is inefficient and the latter method fails to capture the joint posterior dependence structure of multivariate parameters. We develop a new algorithm for computing the WASP of multivariate parameters that is easy to implement and is useful for computing the WASP in any model where the posterior distribution of parameter belongs to a location-scatter family of probability measures. The algorithm is introduced for linear mixed-effects models with both implementation details and theoretical properties. Our algorithm outperforms the current state-of-the-art method in inference on the functions of the covariance matrix of the random effects across diverse numerical comparisons.

description: The signal contribution function (SCF) in multivariate curve resolution evaluates signal portions of specific components either in absolute or in relative form related to the integrated signal of all components. In 1999, Gemperline used the summed signal data, and in 2001, Tauler worked with the square-summed relative signal in order to determine the profiles that minimize, respectively maximize, the signal contribution. These profiles approximate the bands of all feasible profiles. Here, Gemperline's approach using the entrywise 1-matrix norm is proved to provide accurate bounds for two-component systems. This revives the approach of summed mass or absorption values with its potentially better chemical interpretability.

description: Recent advances in mathematical programming have made mixed integer optimization a competitive alternative to popular regularization methods for selecting features in regression problems. The approach exhibits unquestionable foundational appeal and versatility, but also poses important challenges. Here, we propose MIP-BOOST, a revision of standard mixed integer programming feature selection that reduces the computational burden of tuning the critical sparsity bound parameter and improves performance in the presence of feature collinearity and of signals that vary in nature and strength. The final outcome is a more efficient and effective L0 feature selection method for applications of realistic size and complexity, grounded on rigorous cross-validation tuning and exact optimization of the associated mixed integer program. Computational viability and improved performance in realistic scenarios is achieved through three independent but synergistic proposals. Supplementary materials including additional results, pseudocode, and computer code are available online.

description: The lauded Renewable Energy Independent Power Producer Procurement Program (REIPPPP) has achieved much in stimulating private sector investment in the renewable energy market in South Africa. Yet, 95% of electricity generated is still from a single source, the state-owned utility Eskom. This paper set out to explore the policy sphere governing electricity generation and identifying possible avenues that can contribute to a more vibrant solar energy market in the most solar abundant province of South Africa, the Northern Cape Province. Licensed mines were identified as low hanging fruit due to a large policy overlap and leeway within existing mining policy. A solar audit of these areas was performed, based on accepted multi-criteria decision analysis techniques, and found that a potential 369 TWh to 679 TWh per annum can be generated, exceeding South Africa's current electricity usage.

description: A quartz crystal microbalance with dissipation monitoring (QCM-D) was employed for in situ investigations of the effect of temperature and light on the conformational changes of a poly (triethylene glycol acrylate-co-spiropyran acrylate) (P (TEGA-co-SPA)) copolymer containing 12–14% of spiropyran at the silica–water interface. By monitoring shifts in resonance frequency and in acoustic dissipation as a function of temperature and illumination conditions, we investigated the evolution of viscoelastic properties of the P (TEGA-co-SPA)-rich wetting layer growing on the sensor, from which we deduced the characteristic coil-to-globule transition temperature, corresponding to the lower critical solution temperature (LCST) of the PTEGA part. We show that the coil-to-globule transition of the adsorbed copolymer being exposed to visible or UV light shifts to lower LCST as compared to the bulk solution: the transition temperature determined acoustically on the surface is 4 to 8 K lower than the cloud point temperature reported by UV/VIS spectroscopy in aqueous solution. We attribute our findings to non-equilibrium effects caused by confinement of the copolymer chains on the surface. Thermal stimuli and light can be used to manipulate the film formation process and the film’s conformational state, which affects its subsequent response behavior.

description: A systematic approach to evaluate Concentrating Solar Power (CSP) plant fleet deployment and sustainable water resource use in arid regions is presented. An overview is given of previous work carried out. Once CSP development scenarios, suitable areas for development, and the water demand from CSP operations were evaluated, appropriate spatiotemporal CSP performance models were developed. The resulting consumptive patterns and the impact of variable resource availability on CSP plant operation are analysed. This evaluation considered the whole of South Africa, with focus on the areas identified as suitable for CSP, in order to study the impact on local water resources. It was found that the hydrological limitations imposed by variable water resources on CSP development are severe. The national annual theoretical net generation potential of wet-cooled Parabolic Trough decreased from 11,277 to 120 TWh, and that of wet-cooled Central Receiver decreased from 12,003 to 170 TWh. Dry cooled versions also experience severe limitations, but to a lesser extent-the national annual theoretical net generation potential of Parabolic Trough decreased from 11,038 to 512 TWh, and that of Central Receiver decreased from 11,824 to 566 TWh. Accordingly, policy guidelines are suggested for sustainable CSP development and water resource management within the context of current South African water use regulation.

description: Recent advances in mathematical programming have made mixed integer optimization a competitive alternative to popular regularization methods for selecting features in regression problems. The approach exhibits unquestionable foundational appeal and versatility, but also poses important challenges. Here, we propose MIP-BOOST, a revision of standard mixed integer programming feature selection that reduces the computational burden of tuning the critical sparsity bound parameter and improves performance in the presence of feature collinearity and of signals that vary in nature and strength. The final outcome is a more efficient and effective L 0 feature selection method for applications of realistic size and complexity, grounded on rigorous cross-validation tuning and exact optimization of the associated mixed integer program. Computational viability and improved performance in realistic scenarios is achieved through three independent but synergistic proposals. Supplementary materials including additional results, pseudocode, and computer code are available online.

Psorophora pygmaea

description: Psorophora (Grabhamia) pygmaea (Theobald, 1903)
Van der Kuyp (1953, 1954) recorded Ps. pygmaea from the Rolandus Channel on Sint Maarten. During the 2018 survey, this species was not observed at this location, but was found in shallow ponds on a flooded lawn in the Belvedere district, but only during the rainy season. The species is known to require recently flooded plains for their eggs to hatch (Belkin et al., 1970), which explains why they were not observed during the dry season. Sint Maarten has lowlands with poorly drained mineral soils, in strong contrast with the soils of Sint Eustatius and Saba which consist of better drained sandy-loam and are more steep (Veenenbos, 1955). This makes it unlikely that rainwater pools form long enough for the larvae of Ps. pygmaea to develop on Sint Eustatius and Saba.

description: In homogeneous catalysis, the application of organic solvent nanofiltration (OSN) has become a well-known alternative to common recycling methods. Even though some OSN membranes are commercially available, their classification and the scope of application have to be determined for the specific solvent mixture. The commercial membrane Evoniks DuraMem® 300 was tested in a mixture of ethanol, ethyl acetate, and cyclohexane with magnesium triflate as possible catalyst. The cross permeate fluxes were measured for two transmembrane pressures and the hydrodynamic radii of the components were determined. Some of the components in the ternary mixture are retained, which makes the membrane also suitable for fractioning thereof. © 2019 The Authors. Published by WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

description: Urban climate is determined by a variety of factors, whose knowledge can help to attenuate heat stress in the context of ongoing urbanization and climate change. We study the influence of city size and urban form on the Urban Heat Island (UHI) phenomenon in Europe and find a complex interplay between UHI intensity and city size, fractality, and anisometry. Due to correlations among these urban factors, interactions in the multi-linear regression need to be taken into account. We find that among the largest 5,000 cities, the UHI intensity increases with the logarithm of the city size and with the fractal dimension, but decreases with the logarithm of the anisometry. Typically, the size has the strongest influence, followed by the compactness, and the smallest is the influence of the degree to which the cities stretch. Accordingly, from the point of view of UHI alleviation, small, disperse, and stretched cities are preferable. However, such recommendations need to be balanced against e.g. positive agglomeration effects of large cities. Therefore, trade-offs must be made regarding local and global aims.

description: This paper focuses on the development of a participatory planning approach for local energy sustainability. The characteristics of a complex problem were reviewed to establish that the problem of sustainable energy at a local government level is complex. In order to better manage complex problems, the literature shows that soft operational research or problem-structuring methods need to be applied, and hence these methods were used as a starting point for developing a participatory planning approach. The requirements for a planning approach were elicited, namely that the approach must be participative and inclusive, holistic, simple and transparent. In addition, the approach must include the identification and assessment of risks as part of the deliberation process, the development of a realistic action plan must be attainable at the end of the stakeholder engagement, the approach must be dynamic, and should be formalised with clear institutional arrangements. A novel participatory approach, namely EDAS-to Explore, Design and Act for Sustainability-was then developed, applied, and evaluated as part of a case study with a local municipality in theWestern Cape Province of South Africa. The insights are relevant not only for local governments, but for any institution on a journey towards sustainability.
Paneth cell-microbiota crosstalk orchestrates intestinal homeostasis

description: Paneth cells are specialized intestinal epithelial cells that are the primary source of lysozyme, a β-1,4-N-acetylmuramoylhydrolase that targets bacterial cell walls. Paneth cell metaplasia in the distal colon and aberrant lysozyme production have been linked to Inflammatory Bowel Disease (IBD) and other gastrointestinal diseases. However, the causal relationship between Paneth cell defects and disease pathogenesis is not well understood. First, the role of abnormal lysozyme production in perpetuating colonic inflammation was investigated. Targeted disruption of Paneth cell-produced lysozyme protected mice from DSS-induced colitis by eliciting a type 2 immune response. Lysozyme deficiency impaired innate immune responses to microbe-associated molecular patterns and facilitated the expansion of lysozyme-sensitive bacterial species, notably Ruminococcus gnavus, a pathobiont enriched in IBD patients. Ectopic lysozyme production in the colonic epithelium, a hallmark of IBD, abrogated the lysozyme-sensitive bacteria and exacerbated colitis in mice. While R. gnavus colonization of antibiotics-treated Lyz1-/- mice elicited a type 2 immune response and impeded experimental colitis, it drove a pro-inflammatory response in antibiotics-treated WT mice. Thus, Paneth cell-specific lysozyme defines the microbial landscape, which modulates the inflammatory response. Determining and understanding the molecular cues that enable Paneth cells to participate in this immune surveillance would have a significant consequence on human health and disease. Single-cell RNA sequencing of Paneth cells from different microbial milieus revealed regional and functional heterogeneity in subsets of Paneth cells dictated by commensal microbiota and sensitivity to antibiotics-induced dysbiosis while robustly altered by an enteric pathogen. The induction of CD74 in subsets of Paneth cells after Salmonella infection was also found in murine enteritis models caused by enteric pathogens, exaggerated TNF production, allogeneic T cell transplantation, or radiation. In addition, these CD74-expressing Paneth cell subsets exhibited profound secretion of atypical antimicrobial peptides and reactive oxygen species and communicated with immune cells to regulate the inflammatory response. Ablating MyD88-mediated bacterial sensing in Paneth cells diminished the inflammation-activated Paneth cell subset and systemic inflammation. Thus, microbiota-driven Paneth cell heterogeneity modulates the host’s inflammatory response. Together, this study highlights the reciprocal crosstalk present between Paneth cells and gut microbiota and its subsequent regulation of the intestinal inflammatory tone.

description: A deep drilling campaign was performed at Lake Van (Turkey) to enhance the understanding of the paleoenvironmental conditions of the Middle East. Cores were collected, and the sediments are mainly composed of clayey silts and tephra deposits. Spectral gamma ray data were acquired (0–210 m below lake floor), and the uranium data were used for cyclostratigraphic studies to estimate the sedimentation rates and the time of deposition. Detection and analysis of climate cycles require continuous sedimentation and cannot be applied to these sediments which include numerous tephra layers. Therefore, these layers were removed, and a synthetic log was created (cumulative thickness of the tephra ≈50 m; remaining lacustrine sediments ≈160 m). High amplitudes were detected and correlated to Milanković cycles. Their evolution was analyzed using the sliding window technique. The sedimentation rates varied from 22 to 33 cm/ka in the upper section. The sediments between the lake floor and a depth of 210 m were deposited over a period of 587 ka. Our results agree with core interpretations (e.g., correlation of total organic carbon with marine isotope stages) which suggest a time span of deposition of 600 ka. High-frequency cycles were detected and correlated with interstadials from the North Greenland δ18O record for the past 75 ka. The two datasets agreed closely. We conclude that climate signals, even on sub-Milanković scale, are imprinted in uranium of these sediments, and cyclostratigraphic methods are applicable if event layers are subtracted from the sediment record.
