description: This 3D reconstruction of a coral reef was made from a series of photos recorded in situ by the remotely operated underwater robot (ROV) Ariane of the French Oceanographic Fleet (FOF) during the CALADU-2019 cruise. The 3D reconstruction algorithms were developed by the "Unité des Systèmes sous-marins" from Ifremer. The 3D reconstruction was produced by the scientists, was cleaned by pix-factory (pix-factory.eu) and the 2D travelling video was generated by pix-factory. 
Scientists are now able to obtain digital reconstructions of an entire ecosystem, enabling them to work in precise detail on deep-sea populations. This georeferenced model is to scale. It is used to count the different species, to measure sizes and surfaces and to calculate densities. It also allows to obtain the depths at which the species are found.

description: [Objectives] This study aimed to provide a basis for the management of nitrogen, phosphorus and potassium nutrients in eum-orthic anthrosols and the fertilization of crops. [Methods] Using the indoor culture method, the contents of total nitrogen, available phosphorus and available potassium in eum-orthic anthrosols under three different moisture conditions: long-term drying, long-term logging and alternate drying and logging were analyzed and compared. [Results] The total nitrogen content was higher under the moisture condition of long-term drying. The minimum (0.60 g/kg) appeared on day 30, and the maximum (0.74 g/kg) appeared on day 120, increased by 8.8% compared with the minimum. The available phosphorus content was also higher under the moisture condition of long-term drying. The minimum (16.9 mg/kg) appeared on day 60, and the maximum (22.5 mg/kg) appeared on day 120, increased by 33.1% compared to the minimum. The available potassium content showed a downward trend under long-term logging, and was higher than those under the other two moisture conditions. The maximum (150 mg/kg) appeared on day 30, and the minimum (136 mg/kg) appeared on days 75 and 90, reduced by 9.3% compared with the maximum. [Conclusions] Water plays a positive role in activating nutrients. Different nutrients have different responses to different moisture conditions.

description: Every year 20–30 million metric tonnes of fish, one-third of the global fish catch, is used to produce aquafeeds. This practice is unsustainable and a critical threat to the viability of the global aquafeed industry. Efforts to find alternatives that totally match or improve the cost-effectiveness and nutritional performance of wild fish products, while reducing the burden on the natural environment, have failed, until recently. Now, an innovation using natural marine microbial processes has achieved this goal – a world-first success, improving the sustainability and cost-effectiveness of aquafeeds. The technology uses natural marine microbial processes to bio-convert plant wastes, such as bagasse or rice straw, into a bioactive product (Novacq™) that improves the growth and health of farmed prawns and eliminates the need for any wild harvest fishmeal in prawn feeds. The technology is patented and in full-scale commercial production by several licensees in a number of countries. The development of Novacq™ (an abbreviation of ‘novel aquafeed’ ingredient) is an example of why we need to rethink the way we produce aquafeeds. We need to continue to learn from nature how to produce sustainable aquafeeds and industrialise these processes in costeffective ways.

description: We measure an anomalous magnetoresistance peak within the lowest Landau level (nu = 1) minimum of a two-dimensional hole system on (110) GaAs. Self-consistent calculations of the valence band mixing show that the two lowest spin-index Landau levels anticross in a perpendicular magnetic field B consistent with where the experimental peak is measured, Bp. The temperature dependence of the anomalous peak height is interpreted as an activated behavior across this anticrossing gap. Calculations of the spin polarization in the lowest Landau levels predict a rapid switch from about -3/2 to +3/2 spin at the anticrossing. The peak position Bp is shown to be affected by the confinement electrostatics, and the utility of a tunable anticrossing position for spintronics applications is discussed.

Evaluation of methods for estimating the cross-correlation coefficient between closely spaced diversity antennas
Creators: name: Hynes, Christopher
Publisher: name: University of British Columbia
Year: 2011

description: A growing number of cellular handsets and other personal wireless communications devices use diversity combining and/or MIMO techniques in order to boost link performance and reliability and therefore must incorporate closely spaced antennas. The cross-correlation coefficient between such antennas in fading environments is a key predictor of the success of such schemes. In recent years, several methods for predicting this parameter based upon measurement or simulation of either their field or terminal characteristics have been proposed. Here, we compare the performance of such methods for the case of two closely spaced half-wavelength dipole antennas subject to the assumptions that (1) the angle of arrival distribution is uniformly distributed in three-dimensions, (2) the polarization of the incident waves are uncorrelated to each other and individually uncorrelated in different directions and (3) the cross-polarization power ratio is unity. We consider two diversity antenna configurations. In the first, one antenna is loaded while the other is terminated by an open circuit, e.g., as in the case of switched diversity schemes. In the second, both antennas are attached to matched loads, e.g., as in the case of diversity combining or MIMO schemes. The best results were obtained using isolated far-field pattern coherence when one antenna is open-circuited and both antennas have characteristics approaching those of minimal scattering antennas. However, our results also indicate that the majority of recently proposed methods for estimating the cross-correlation coefficient are surprisingly inaccurate, especially when both antennas are attached to matched loads. Furthermore, we conclude that the total efficiency of the antennas is just as important as their cross-correlation in determining the performance of a multiple antenna system.

description: The benefits of better food waste management extend to community-building, liveability and poverty reduction in cities. Waste-to-energy (WtE) technologies provide elegant solutions for food waste management with tangible and usable products including energy and fertiliser, and attractive environmental and social benefits. When combined with food security they provide a powerful case for city and rural communities alike. The majority of waste-to-energy facilities in the world are in Europe, Japan, and the US. In developing countries such as African nations, a very limited share of waste is recovered and reused, and only major or capital cities have waste management systems. In a number of these countries the use of waste to generate electricity could have a significant impact. Waste can make a very high contribution to providing electricity to citizens and alleviating energy poverty, especially in countries with little access to electricity and low electricity consumption per capita. For isolated, rural and less wealthy populations, the benefits of an effective circular economy are even more direct than for a Western urban population. The production of biogas from organic waste via anaerobic digestion is one such technology that fits perfectly in a circular economy and engenders the energy independence needed by these communities. This case study presentation gives an overview of the different waste-to-energy technology options that exist, and highlights some key innovations across the globe. A particular focus is novel approaches that have been used in developing countries, and the impacts on food loss and waste, livelihoods and food security.

description: The subject of moving curves (and surfaces) in three dimensional space (3-D) is a fascinating topic not only because it represents typical nonlinear dynamical systems in classical mechanics, but also finds important applications in a variety of physical problems in different disciplines. Making use of the underlying geometry, one can very often relate the associated evolution equations to many interesting nonlinear evolution equations, including soliton possessing nonlinear dynamical systems. Typical examples include dynamics of filament vortices in ordinary and superfluids, spin systems, phases in classical optics, various systems encountered in physics of soft matter, etc. Such interrelations between geometric evolution and physical systems have yielded considerable insight into the underlying dynamics. We present a succinct tutorial analysis of these developments in this article, and indicate further directions. We also point out how evolution equations for moving surfaces are often intimately related to soliton equations in higher dimensions.

title: Lipoxygenase Activity in Diatoms : A New Tool to Study the Antiproliferative Effects of Diatoms on Copepod Reproduction
Creators: name: Gerecht, Andrea Cornelia
Publisher: name: The Open University
Year: 2010

description: The deleterious effects of maternal diatom diets on copepod embryonic development have been puzzling the scientific community for the past 15 years. Since the discovery of the first anti-mitotic compounds, polyunsaturated aldehydes deriving from fatty acid oxidation,our knowledge of the oxylipin metabolism in diatoms has been continuously increasing. Not only have new oxylipin compounds been identified, but it is becoming apparent thatoxylipin metabolism is highly complex and specific.

This thesis contributes to the understanding of oxylipin metabolism in diatoms by studying the activity of diatom lipoxygenases, the enzymes responsible for the first oxidative step in transforming polyunsaturated fatty acids into oxylipins. Lipoxygenase activity was measured by a colorimetric and a polarographic assay, and its relationship to oxylipin production was examined. Lipoxygenase metabolism in diatoms was studied under natural conditions during a bloom at sea, under semi-natural conditions during a mesocosm experiment, and in the laboratory, with special emphasis on Skeletanema marinai. The effect of diatom oxylipin production on copepod reproductive success was also examined.

Increased oxylipin production was found with the onset of the stationary phase in culture and during the decline of the mesocosm bloom, which indicates a regulatory role foroxy lipins in bloom demise, even though this could not be verified at sea. Lipoxygenase activity and oxylipin production were highly variable and specific to the level of clones.The most important conclusion to be drawn from the present experiments is the lack ofcorrelation between lipoxygenase activity and oxylipin production. This strongly indicates that other compounds still need to be identitied and that we do not yet have a complete picture of oxylipin metabolism in diatoms.

We demonstrate the application of this framework to U(1) gauge theory in two spacetime dimensions, and find that near critical points in parameter space the approach is orders of magnitude more efficient at sampling topological quantities than more traditional sampling procedures such as Hybrid Monte Carlo and Heat Bath.

description: Feedback wurde durch die Veröffentlichung von Hatties „Visible Learning“ als einer der häufigsten untersuchten und gleichzeitig einer der wirksamsten Einflussfaktoren auf den Lernerfolg hervorgehoben. Hattie und Timperley veröffentlichten bereits ein Jahr zuvor ein Modell des möglichst wirksamsten Feedbacks. Der explizite Transfer in den Unterricht fehlt jedoch. Im Schulalltag der Sekundarstufe sind Feedbackmethoden zwar verbreitet, tragen dennoch oft nicht zu einer Qualitätsentwicklung des Feedbacks und des Feedback-Verhaltens der Lernenden bei. Gerade für Lernende mit besonderen Bedürfnissen gewinnt Feedback enorm an Bedeutung, wenn es von ihnen selbst zu ihrem individuellen Lernprozess gegeben wird. In der vorliegenden Arbeit wird die Idee zur Umsetzung von Feedback im Unterricht entwickelt, praktisch erprobt, evaluiert und mittels mehrerer Durchführungen verglichen. Es ergeben sich daraus Hinweise, dass sich sowohl das Feedback-Verhalten als auch das Selbstkonzept der Lernenden verändern kann.
title: Staphylococcus aureus virulence gene studies : a comparative microarray based approach
Creators: name: Mohamed, Deqa Hassan A.
Publisher: name: The Open University
Year: 2010

description: The development and application of a partial composite S. aureus virulence-associated gene micro array is described. Epidemic, pandemic and sporadic lineages of healthcare associated(HA-) and community-associated (CA-) S. aureus were compared. The clonal population structure was supported but further evidence for large-scale recombination events was obtained. Phage structural genes linked with the CA phenotype were identified and in silico analysis revealed these to be correlated with phage serogroup. CA strains generally carried a PVL-associated phage either of the A or Fb serogroup, whilst the HA strains predominantly carried sero group B phage. It is proposed that carriage of PVL associated phage rather than the specific pvl genes is correlated with the CA phenotype.These findings further support the role of the accessory genome in shaping the epidemiology of S. aureus.

The microarray was used to study gene expression in isogenic strains differing by a deletion in the agr locus. Microarray analysis revealed significant differences between the levels of expression of several genes of the normal and mutant strains. However, RNAIII levels in the non-mutant strain were found to be cell density independent, indicating that the expected quorum sensing mechanism was not functional.

Expression profiles of cells grown under biofilm simulating conditions were compared to their planktonic counterparts. Biofilm cells displayed a typical expression profile that was different from both the actively growing planktonic exponential cells and the planktonic stationary cells. The strongest feature of the biofilm state was high level expression of the haemolysin genes. This model therefore is amenable to exploitation in studies designed to improve our understanding of the mechanisms underlining biofilm survival and regulation after long periods of growth.

description: We present three-dimensional SPH calculations of giant planets embedded in gaseous disks. Our findings are collected into a map of parameter space, exhibiting four distinct regions: Type I migration, gap formation, triggered formation of more planets, and wholly unstable disks. For Type I migration of the planet due to secular interactions with the disk material, the migration rate depends linearly on the disk mass, and is independent of the initial planet mass. For more massive disks, the planet can disturb the disk strongly enough to trigger the collapse of gas into additional giant planets. When additional planets form, their interaction as point masses dominates the subsequent behavior of the system. This mechanism allows for the rapid formation of Jupiter-mass and higher planets. Migration due to interaction with the disk can significantly change the orbits of giant planets in gas disks.

description: We report the discovery of the scattered emission from a hidden broad-line region (BLR) in a Seyfert 2 galaxy, Mrk 573, based on our recent spectropolarimetric observation performed at the Subaru Telescope. This object has been regarded as a type 2 AGN without a hidden BLR by the previous observations. However, our high quality spectrum of the polarized flux of Mrk 573 shows prominent broad (~3000 km/s) H_alpha emission, broad weak H_beta emission, and subtle Fe II multiplet emission. Our new detection of these indications for the presence of the hidden BLR in the nucleus of Mrk 573 is thought to be owing to the high signal-to-noise ratio of our data, but the possibility of a time variation of the scattered BLR emission is also mentioned. Some diagnostic quantities such as the IRAS color, the radio power, and the line ratio of the emission from the narrow-line region of Mrk 573 are consistent with the distributions of such quantities of type 2 AGNs with a hidden BLR. Mrk 573 is thought to be an object whose level of the AGN activity is the weakest among the type 2 AGNs with a hidden BLR. In terms of the systematic differences between the type 2 AGNs with and without a hidden BLR, we briefly comment on an interesting Seyfert 2 galaxy, Mrk 266SW, which may possess a hidden BLR but has been treated as a type 2 AGNs without a hidden BLR.

description: The district of Pulau Burung is situated on peatland plantation under the regency of Indragiri Hilir in the province of Riau. Most of the local people work as coconut farmers. Today, as the mismanagement of peatland agriculture has become increasingly alarming, there is an urgent need to identify the viable method of sustainable agriculture practice in peatland region. Unlike other agriculture practices in peatland that causes the area to be highly flammable, land fire in Pulau Burung has been consistently preventable. This not only enables the community to thrive, but also to improve the social, economy, and environmental aspects of their district. To assess their condition, Tay Juhana Foundation (TJF) conducted interviews with 29 respondents from five villages in Pulau Burung District.

description: Polymorphic Batesian mimics exhibit multiple protective morphs that each mimic different noxious models. Here, we study the genomic transitions leading to the evolution of different mimetic wing patterns in the polymorphic Mocker Swallowtail Papilio dardanus. We generated a draft genome (231 Mb over 30 chromosomes) and re-sequenced individuals of three morphs. Genome-wide SNP analysis revealed elevated linkage disequilibrium and divergence between morphs in the regulatory region of engrailed, a developmental gene previously implicated in the mimicry switch. The diverged region exhibits a discrete chromosomal inversion (of 40 kb) relative to the ancestral orientation that is associated with the cenea morph, but not with the bottom-recessive hippocoonides morph or with non-mimetic allopatric populations. The functional role of this inversion in the expression of the novel phenotype is currently unknown, but by preventing recombination, it allows the stable inheritance of divergent alleles enabling geographic spread and local co-existence of multiple adaptive morphs.

This calculation uses quenched lattice QCD and Luescher's finite box method. Operators for the h and pi+a1 states are used in a correlation matrix which was expanded by varying the smearing and fuzzing levels at source and sink points. Scattering phase shifts for a discrete set of relative pi+a1 momenta are determined using eigenvalues of the correlation matrix and formulae derived by Luescher. The phase shift data is very sparse, but fits to a Breit-Wigner model are made, resulting in a decay width of about 80 MeV.

description: We consider the time-dependent analysis of $B_d\to K_S\ell\ell$ taking into account the time-evolution of the $B_d$ meson and its mixing into $\bar{B}_d$. We discuss the angular conventions required to define the angular observables in a transparent way with respect to CP conjugation. The inclusion of time evolution allows us to identify six new observables, out of which three could be accessed from a time-dependent tagged analysis. We also show that these observables could be obtained by time-integrated measurements in a hadronic environment if flavour tagging is available. We provide simple and precise predictions for these observables in the SM and in NP models with real contributions to SM and chirally flipped operators, which are independent of form factors and charm-loop contributions. As such, these observables provide robust and powerful cross-checks of the New Physics scenarios currently favoured by global fits to $b\to s\ell\ell$ data. In addition, we discuss the sensitivity of these observables with respect to NP scenarios involving scalar and tensor operators, or CP-violating phases. We illustrate how these new observables can provide a benchmark to discriminate among the various NP scenarios in $b\to sμμ$. We discuss the extension of these results for $B_s$ decays into $f_0$, $η$ or $η'$.

The two expressions are actually consistent with each other, but the new one represents a more stringent condition for entanglement and, in our opinion, better explains the original idea of EPR.

Here we address this issue for the first time, using molecular dynamics simulations to investigate the shear-rate dependence of the viscosity of supercooled water as described by the TIP4P/Ice model. We show the existence of a distinct cross-over from Newtonian to non-Newtonian behavior characterized by a power-law shear-thinning regime. The viscosity reduction is due to the decrease in the connectivity of the hydrogen-bond network. Moreover, the shear thinning intensifies as the degree of supercooling increases, whereas the cross-over flow rate is approximately inversely proportional to the Newtonian viscosity. These results stimulate further investigation into possible fundamental relations between these nonequilibrium effects and the quasi-static Newtonian viscosity behavior of supercooled water.

description: Previous studies indicate hypocalcaemia as a potential diagnostic and prognostic marker of corona-virus disease 2019 (COVID-19). Our aim was to investigate these relations in more detail in a large test cohort and an independent validation cohort. We retrospectively included 2792 COVID-19 suspected patients that presented to the emergency department (ED) of two hospitals. Plasma calcium and ionized plasma calcium levels were compared between COVID-19 positive and negative patients, and between severe and non-severe COVID-19 patients using univariate and multivariate analyses in the first hospital (N = 1363). Severe COVID-19 was defined as intensive care unit (ICU) admission or death within 28 d after admission. The results were validated by repeating the same analyses in the second hospital (N = 1429). A total of 693 (24.8%) of the enrolled patients were COVID-19 positive, of whom 238 (34.3%) had severe COVID-19. In both hospitals, COVID-19 positive patients had lower plasma calcium levels than COVID-19 negative patients, regardless of correction for albumin, in univariate and multivariate analysis (Δ0.06–0.13 mmol/L, p N = 567, p Plasma calcium concentrations were lower in COVID-19 positive than COVID-19 negative patients but we found no association with disease severity in multivariate analyses. Further understanding of plasma calcium perturbation may facilitate the development of new preventive and therapeutic modalities for the current pandemic.
Parity-violating Electron Deuteron Scattering and the Proton's Neutral Weak Axial Vector Form Factor
Creators: name: SAMPLE Collaboration

description: We report on a new measurement of the parity-violating asymmetry in quasielastic electron scattering from the deuteron at backward angles at Q2= 0.038 (GeV/c)2. This quantity provides a determination of the neutral weak axial vector form factor of the nucleon, which can potentially receive large electroweak corrections. The measured asymmetry A=-3.51 +/- 0.57(stat) +/- 0.58(sys)ppm is consistent with theoretical predictions. We also report on updated results of the previous experiment at Q2=0.091 (GeV/c)2, which are also consistent with theoretical predictions.

Illusions perdues et le Swedenborgisme Balzacien entre Le serf arbitre de Luther et Le libre arbitre d'Érasme
Creators: name: Sadovska, Evelina
Publisher: name: University of British Columbia
Year: 2011

description: De l'antiquité jusqu'aux nos jours, la question du libre arbitre, étant un des problèmes fondamentaux de la philosophie et de la théologie, a toujours évoqué de vives discussions parmi ses adhérents et ses adversaires. Le but de ce projet est d'examiner l'attitude de l'un des plus grands romanciers du XIX ième siècle, Honoré de Balzac, vis-à-vis de la question du libre arbitre en comparant les idées philosophiques de l'auteur qui se manifestent dans un de ses romans les plus connus, Illusions perdues, avec les doctrines théologiques représentées dans Du serf arbitre de Luther qui nie l'existence du libre arbitre; dans Du libre arbitre d'Érasme, qui, au contraire, soutient le libre arbitre de l'homme; et finalement dans les œuvres mystiques d'Emmanuel Swedenborg, le philosophe et visionnaire suédois qui a beaucoup influencé la vie et les œuvres de Balzac. Cette analyse comparative démontre que, malgré le fatalisme apparent des plusieurs éléments des Illusions perdues, Balzac, comme Swedenborg, croit au libre arbitre de l'homme en soutenant la théorie dite compatibiliste selon laquelle le libre arbitre et le déterminisme sont des idées compatibles l'une avec l'autre.

description: We present optical measurements of phononic excitations in La$_{2/3}$Ca$_{1/3}$MnO$_{3}$ (LCMO) and La$_{2/3}$Sr$_{1/3}$MnO$_{3}$ (LSMO) thin films covering the full temperature range from the metallic ferromagnetic to the insulating paramagnetic phase. All eight phonons expected for the R$\bar{3}$c symmetry in LSMO and 17 out of the expected 25 phonons for the Pnma symmetry in LCMO have been determined. Close to the ferromagnetic-to-paramagnetic transition both compounds reveal an anomalous behavior but with different characteristics. Anomalies in the phononic spectra are a manifestation of the coupling of lattice degrees of freedom (DOF) to electronic DOF. Specifically, the low-frequency external group proves to be an indicator for lattice modifications induced by electronic correlations. The enhanced electron-phonon coupling in LCMO is responsible for Fano-like interference effects of distinct phonon modes with electronic continuum excitations: we observe asymmetric phonon line shapes, mode splitting and spectral weight transfer between modes.

description: Vaccine effectiveness against COVID-19 needs to be assessed in diverse real-world population settings. A cohort study of 805,741 residents in Skåne county, Southern Sweden, aged 18–64 years, of whom 26,587 received at least one dose of the BNT162b2 vaccine. Incidence rates of COVID-19 were estimated in sex- and age-adjusted analysis and stratified in two-week periods with substantial community spread of the disease. The estimated vaccine effectiveness in preventing infection ≥7 days after second dose was 86% (95% CI 72–94%) but only 42% (95% CI 14–63%) ≥14 days after a single dose. No difference in vaccine effectiveness was observed between females and males. Having a prior positive test was associated with 91% (95% CI 85–94%) effectiveness against new infection among the unvaccinated. A satisfactory effectiveness of BNT162b2 after the second dose was suggested, but with possibly substantially lower effect before the second dose.

description: Napiergrass (Pen11isetum purpureum Schumach.) (2n=28) has proven to be an excellent male parent in crosses with cytoplasmic male-sterile lines of pearl millet (P. g/aucum (L.) K. Schum.) (2n= 14) 'for the development of superior interspecific Pen11isetum forage hybrids (IPFH). These hybrids (3x=21) are sexually propagated and combine the leafiness and forage quality of pearl millet with the high dry matter yield and perennial nature of napiergrass. Three lPFH (101, 102, and -.103 developed by W. H. Hanna) and local photoperiod-sensitive forage sorghum Millo Blanco (Sorghum bicolor (L) M~nch) were compared at cutting intervals (CI) of 45, 65, and 85 days, equivalent to seven, five, and four harvests, respectively, at two locations (Oxisol and Ultisol) in Puerto Rico. Across locations, dry forage yields (DFY) of the lPFH averaged 6.0, 10.4, and 16.0 t ha-1 at the 45-, 65-, and 85- day CI, respectively, representing 119, 79, and 127 % more DFY than that of Millo Blanco. From the data obtained, it appears that the optimum time for harvesting these grasses is 65 days. At this stage, the DFY were 5.8, 9.5, 11.4, and 10.3 t ha-I for Millo Blanco and the three IPFH, respectively. The in vitro dry matter digestibility for the same CI ranged from 42 to 52 % and 'the crude protein content from 6 to 11 % . The perennial nature of the interspecific hybrids plus their production of excellent quality forage attest to their potential as valuable new forage grasses for the tropics.
