description: The predicted spatial development of helical structures along an expanding jet are used to model observed structures and motions in the 3C 120 jet. Proper motions of helical components associated with the pattern and of other components that move through the pattern provide estimates of flow and helical pattern speeds. Theoretical modeling allows determination of sound speeds as a function of jet viewing angle. Jet morphology argues against viewing angles larger than 12 deg. At a 12 deg viewing angle the most likely scenario involves a decline in jet sound speed from c/3 < a_j < c/1.7 at ~0.5 mas from the core to 0.1c < a_j < 0.25c at ~25 mas from the core accompanied by some acceleration in the jet flow from Lorentz factor < 5 to Lorentz factor > 7. At smaller viewing angles the jet sound speed is lower and at a 6 deg viewing angle the jet sound speed is about a factor 2 less but the flow Lorentz factor is comparable. The decline in radio intensity is on the order of what would be associated with isothermal jet expansion. Knot interknot intensity variations are greater than would be expected from adiabatic compressions associated with the helical twist and we infer the presence of a shock along the leading edge of the helical twist. Our results imply that the macroscopic heating of the expanding jet fluid is less than the microscopic energization of the synchrotron radiating relativistic electrons.

Ecological links between emergent macrophytes and associated periphyton and benthic communities in a coastal reservoir littoral zone
Creators: name: Wilson, Sandra Joan
Publisher: name: University of British Columbia
Year: 2010

description: A study conducted in Stave Reservoir, near Mission British Columbia, examined the linkages between flooded shoreline vegetation and associated periphyton and benthic communities in a coastal reservoir drawdown zone. Two native perennial species, woolgrass (Scirpus cyperinus) and lenticulate sedge (Carex lenticularis), and an annual agronomic species, fall rye (Secale cereale L.) were used in the study. A total of 108 pots containing either one of the plant species or barren substrate (i.e. no vegetation) were installed within three elevation bands in the inundated reservoir drawdown zone in June 2000. Samples were retrieved monthly over the period of inundation, with the final samples being removed in early September 2000. The effects of planting elevation, vegetation species and time on endpojnts including plant biomass and nutrient composition, periphyton density and biovolume, and benthos abundance were examined. Fall rye decomposed quickly, losing approximately 80% of its foliar biomass after one month of submergence. Woolgrass and sedge foliage decomposed much more slowly, losing only 30% and 55%, respectively, of their aboveground biomass by the final sample date. There was evidence that nitrogen was translocated from shoots to roots fairly quickly upon inundation in all three plant species. Phosphorus was lost rapidly from the fall rye foliage with no concurrent increase in the roots, suggesting that rather than being translocated to the roots, phosphorus was leached from the plant material. No trends were noted for phosphorus for the perennial species. The periphyton communities associated with all plants types were dominated by diatoms. The maximum diatom density was approximately 112,000 cells/m2 observed in the final sample period. Oligochaetes and chironomids were the most dominant benthic taxa, accounting for 63% of all benthic organisms. The presence of vegetation increased the number of benthic organisms by 3 times, and benthic taxa by 1.7 times in comparison to barren substrate. There was no significant difference in total benthos abundance between the three plant species; however, distinct groupings of benthic community composition associated with the control, fall rye and perennial plant species were noted using the nonmetric multidimensional scaling (NMS) ordination technique.

description: Ad creative is one of the main mediums for e-commerce advertising. In our approach we decouple this dynamic creative optimization into two stages, a cascaded structure that can trade off between effectiveness and efficiency. In the first stage, we train an automatic creative optimization architecture based on autoco to simulate complex interactions between creative elements. Although we obtained the ranking of different creatives under a sku, because we bucketed and merged historical data according to periods, this confuses the ctr diversity of the same ad creatives on different days and weakens the ability to separate ambiguous samples. Therefore, we propose a transformer-based rerank model. With the help of the rank model, we propose a distillation method to learn the relative order of ideas and extract the ranking knowledge to guide the rerank learning. The creative order soft labels under each sku are generated by the rank model to alleviate the dilemma that a large number of under-represented creatives cannot obtain real labels. Through the knowledge diffusion of rerank, the ambiguous samples are associated with the positive and negative samples. Cascade rerank and autoco to output the estimated value of the synthetic ad image. In the second stage, we designed a bandit model, and the bandit selected one of the output ad of the first stage for timely delivery. Experimental results show that our method can outperform competing baselines in terms of sctr. Online A/B testing shows that our method improves ctr by 10% compared to the baseline.

description: We use MMT spectroscopy and deep Subaru Hyper Suprime-Cam (HSC) imaging to compare the spectroscopic central stellar velocity dispersion of quiescent galaxies with the effective dispersion of the dark matter halo derived from the stacked lensing signal. The spectroscopic survey (the Smithsonian Hectospec Lensing Survey) provides a sample of 4585 quiescent galaxy lenses with measured line-of-sight central stellar velocity dispersion ($σ_{\rm SHELS}$) that is more than 85% complete for $R < 20.6$, $D_{n}4000> 1.5$ and $M_{\star} > 10^{9.5}{\rm M}_{\odot}$. The median redshift of the sample of lenses is 0.32. We measure the stacked lensing signal from the HSC deep imaging. The central stellar velocity dispersion is directly proportional to the velocity dispersion derived from the lensing $σ_{\rm Lens}$, $σ_{\rm Lens} = (1.05\pm0.15)σ_{\rm SHELS}+(-21.17\pm35.19)$. The independent spectroscopic and weak lensing velocity dispersions probe different scales, $\sim3$kpc and $\gtrsim$ 100 kpc, respectively, and strongly indicate that the observable central stellar velocity dispersion for quiescent galaxies is a good proxy for the velocity dispersion of the dark matter halo. We thus demonstrate the power of combining high-quality imaging and spectroscopy to shed light on the connection between galaxies and their dark matter halos.

description: The ecological policy of European Union is in considerable grade based on the concept of sustainable development. It defines the main directions of industrial activities in this field, inclusive of enterprises in the agri-food sector. The dairy companies because of their production are polluting the natural environment with respect to the atmosphere, water and ground. The domestic companies have to make an effort leading to the ecologisation of production process, i.e. to initiate proenvironmental activities in their broad sense. This behaviour is connected with the necessity of adaptation to the requirements of the EU directives. The dairy companies began to implement these activities after Polish accession to the EU. / Synopsis. Polityka ekologiczna Unii Europejskiej, oparta w znacznej mierze o zasady zrównoważonego rozwoju, określa główne kierunki działań przedsiębiorstw produkcyjnych, w tym przedsiębiorstw sektora rolno-spożywczego. Przedsiębiorstwa mleczarskie w toku produkcji obciążają środowisko naturalne pod względem zanieczyszczenia zarówno atmosfery, jak i wód i gleby. Przedsiębiorstwa rodzime chcąc sprostać wymaganiom stawianym przez dyrektywy unijne muszą podejmować działania zmierzające do ekologizacji procesu produkcji, czyli do wprowadzania szeroko pojmowanych działań prośrodowiskowych w obrębie swojej jednostki. Przedsiębiorstwa mleczarskie po wstąpieniu Polski do UE takie działania zaczęły wdrażać.

description: Ten-eleven translocation (TET) proteins are DNA dioxygenases that mediate active DNA demethylation. TET3 is the most highly expressed TET protein in thymic developing T cells. TET3, either independently or in cooperation with TET1 or TET2, has been implicated in T cell lineage specification by regulating DNA demethylation. However, TET-deficient mice exhibit complex phenotypes, suggesting that TET3 exerts multifaceted roles, potentially by interacting with other proteins. We performed liquid chromatography with tandem mass spectrometry in primary developing T cells to identify TET3 interacting partners in endogenous, in vivo conditions. We discover TET3 interacting partners. Our data establish that TET3 participates in a plethora of fundamental biological processes, such as transcriptional regulation, RNA polymerase elongation, splicing, DNA repair, and DNA replication. This resource brings in the spotlight emerging functions of TET3 and sets the stage for systematic studies to dissect the precise mechanistic contributions of TET3 in shaping T cell biology.
Quantum Mott Transition and Multi-Furcating Criticality

description: Phenomenological theory of the Mott transition is presented. When the critical temperature of the Mott transition is much higher than the quantum degeneracy temperature, the transition is essentially described by the Ising universality class. Below the critical temperature, phase separation or first-order transition occurs. However, if the critical point is involved in the Fermi degeneracy region, a marginal quantum critical point appears at zero temperature. The originally single Mott critical point generates subsequent many unstable fixed points through various Fermi surface instabilities induced by the Mott criticality characterized by the diverging charge susceptibility or doublon susceptibility. This occurs in marginal quantum-critical region. Charge, magnetic and superconducting instabilitites compete severely under these critical charge fluctuations. The quantum Mott transition triggers multi-furcating criticality, which goes beyond the conventional concept of multicriticality in quantum phase transitions. Near the quantum Mott transition, the criticality generically drives growth of inhomogeneous structure in the momentum space with singular points of flat dispersion on the Fermi surface. The singular points determine the quantum dynamics of the Mott transition by the dynamical exponent $z=4$. We argue that many of filling-control Mott transitions are classified to this category. Recent numerical results as well as experimental results on strongly correlated systems including transition metal oxides, organic materials and $^3$He layer adsorbed on a substrate are consistently analyzed especially in two-dimensional systems.

description: Interferon lambda (IFN-λ, type III IFN, IL-28/29) is a family of antiviral cytokines that are especially important at barrier sites, including the maternal-fetal interface. Recent discoveries have identified important roles for IFN-λ during pregnancy, particularly in the context of congenital infections. Here, we provide a comprehensive review of the activity of IFN-λ at the maternal-fetal interface, highlighting cell types that produce and respond to IFN-λ in the placenta, decidua, and endometrium. Further, we discuss the role of IFN-λ during infections with congenital pathogens including Zika virus, human cytomegalovirus, rubella virus, and Listeria monocytogenes. We discuss advances in experimental models that can be used to fill important knowledge gaps about IFN-λ-mediated immunity.

description: We use the first 25% of the DEEP2 Galaxy Redshift Survey spectroscopic data to identify groups and clusters of galaxies in redshift space. The data set contains 8370 galaxies with confirmed redshifts in the range 0.7 <= z <= 1.4, over one square degree on the sky. Groups are identified using an algorithm (the Voronoi-Delaunay Method) that has been shown to accurately reproduce the statistics of groups in simulated DEEP2-like samples. We optimize this algorithm for the DEEP2 survey by applying it to realistic mock galaxy catalogs and assessing the results using a stringent set of criteria for measuring group-finding success, which we develop and describe in detail here. We find in particular that the group-finder can successfully identify ~78% of real groups and that ~79% of the galaxies that are true members of groups can be identified as such. Conversely, we estimate that ~55% of the groups we find can be definitively identified with real groups and that ~46% of the galaxies we place into groups are interloper field galaxies. Most importantly, we find that it is possible to measure the distribution of groups in redshift and velocity dispersion, n(sigma,z), to an accuracy limited by cosmic variance, for dispersions greater than 350km/s. We anticipate that such measurements will allow strong constraints to be placed on the equation of state of the dark energy in the future. Finally, we present the first DEEP2 group catalog, which assigns 32% of the galaxies to 899 distinct groups with two or more members, 153 of which have velocity dispersions above 350km/s. We provide locations, redshifts and properties for this high-dispersion subsample. This catalog represents the largest sample to date of spectroscopically detected groups at z~1.

Challenges with measuring tissue factor antigen and activity in human plasma

name: Sachetto, Ana T. A.
Publisher: name: Elsevier
Year: 2024

description: Tissue factor (TF) is a transmembrane protein that in association with its ligand factor (F) VII/FVIIa activates blood coagulation. TF is highly procoagulant and even very small amounts can activate blood coagulation. Levels of TF-positive extracellular vesicles (EVs) are increased in blood in diseases associated with thrombosis. However, it is challenging to accurately quantify the very low levels of TF in blood. Activity-based assays have higher sensitivity and specificity than antigen-based assays. Many anti-human TF antibodies have been generated but they differ in their affinity for TF and bind to different epitopes. They can be divided into two groups: those that compete with FVIIFVIIa binding to TF and those that bind to both TF and the TF-FVII/VIIa complex. Commercial enzyme-linked immunosorbent assays (ELISA) are commonly used to measure TF antigen in plasma but have low sensitivity and specificity for the detection of TF antigen in plasma. Flow cytometry is used to measure TF antigen on EVs but also has low sensitivity and specificity. Functional TF activity assays should be performed in the presence and absence of an inhibitory anti-TF antibody to distinguish between TF-dependent and TF-independent FXa generation because FVIIa can activate FX in the absence of TF. Tissue factor pathway inhibits the TF-FVIIa complex and reduces TF activity of isolated EVs. Two commercial assays are available for the measurement of TF activity of EVs isolated from human plasma. Measurement of TF activity of EVs isolated from plasma may be a useful biomarker of thrombotic risk in different diseases.

description: Gehsteigvorziehungen verbessern die Sichtbarkeit von querenden FußgängerInnen und Fahrzeugen auf Straßen mit Parkstreifen. Sie verkürzen die Querungslänge und bieten eine sichere Aufstellfläche für den Fußverkehr. Im ersten Teil dieser Arbeit werden die nationalen Normen und Richtlinien aus Österreich, Deutschland und der Schweiz über Gehsteigvorziehungen an ungeregelten Kreuzungen verglichen. Im zweiten Teil werden 100 bestehende Wiener Gehsteigvorziehungen überprüft, um herauszufinden, woran es liegt, wenn die erforderlichen Sichtweiten nicht erreicht werden; was 81 von 100 Mal der Fall war. Die meisten Gehsteigvorziehungen waren schmäler als der angrenzende Parkstreifen, oft wären die erforderlichen Sichtweiten bei Erweiterung der Gehsteigvorziehung bis zum Fahrbahnrand erreicht worden. Im nächsten Schritt wurde mittels Videoanalyse FußgängerInnenverhalten analysiert, um die Ansätze in den Richtlinien für Gehsteigvoziehungen zu evaluieren. Die Anhaltepunkte von FußgängerInnen wurden erfasst und die Distanz zur Gehsteigkante und zur Fahrbahn gemessen. Die Verteilung der Anhaltepunkte war breit gestreut, es zeigte sich eine Tendenz zur Orientierung an der Gehsteigkante. Zum Abschluss dieser Arbeit werden Empfehlungen ausgesprochen, wie zukünftige Richtlinien über Gehsteigvorziehunge aussehen könnten.
description: Curb extensions improve the visibility of pedestrians and vehicles on streets with on-street parking. They shorten the crossing distance and provide a secure waiting area for pedestrians. In the first part of this thesis, the national guidelines of Austria, Germany and Switzerland about curb extensions at non signalized crossings are compared. In the second part, 100 existing curb extensions in Vienna are reviewed in order to identify the main problems, where the required sight distances are not achieved; which was the case in 81 of the 100 sites. Most of the recorded curb extensions did not reach out to the lane, but were smaller than the adjacent parking lane. Many would have reached the required sight distances if they were extended to the lane. In a next step, pedestrian behaviour was observed by a video analysis to evaluate the approach of the guidelines of how to design curb extensions. The stopping points of pedestrians were recorded and set in relation to both, the curb an the lane. The distribution of stopping points did not focus clearly on one point, but showed that pedestrians rather orient themselves at the curb than at the lane. The thesis ends with recommendations about how future guidelines about curb extensions could look like.

description: We present a structural analysis of nearby galaxies in spiral-spiral pairs in optical BVRI bands and compare with the structures of isolated spiral galaxies and galaxies in ongoing mergers. We use these comparisons to determine how galaxy structure changes during galaxy interactions and mergers. We analyze light concentration (C), asymmetry (A), and clumpiness (S) parameters, and use the projections of CAS parameter space to compare these samples. We find that the CAS parameters of paired galaxies are correlated with the projected separations of the pair. For the widest and closest pairs, the CAS parameters tend to be similar to those of isolated and ongoing major mergers (ULIRGs), respectively. Our results imply that galaxy CAS morphology is a robust quantity that only changes significantly during a strong interaction or major merger. The typical time-scale for this change in our paired sample, based on dynamical friction arguments, is short, t ~ 0.1 - 0.5 Gyr. We find average enhancement factors for the spiral pair asymmetries and clumpiness values of ~2.2 and 1.5. The S parameter, which is related to star formation activity, has a moderate level of enhancement suggesting that this activity in modern spirals depends more on internal processes than on external conditions. We furthermore test the statistical criterion for picking up interacting galaxies in an automated way by using the A-S projection plane. The diversity of our spiral pair sample in the CAS space suggests that structural/SF/morphological properties of interacting galaxies change abruptly only when the interaction becomes very strong and that the criteria for finding galaxies involved in major mergers from Conselice (2003) is effective.

title: Medicalisation and Resistance in Post-Emergency India 1977-2020
titleType: Subtitle
Creators: name: Price, Rianna
Publisher: name: Lancaster University
Year: 2024

description: This thesis represents the first comprehensive history of the
 medicalisation of queerness in the post-Emergency context in India
 (1970-2020). It is also the first history of resistance to medicalised
 narratives and practice. Through analysing institutional records,
 specifically psychiatric studies, and queer-created sources, such as print
 media, online blogs, and oral testimony, the thesis traces the
 relationships between medicine, culture, and queerness in the

 Indian context. The thesis uses previously unused source bases to create a
 queer-led history of both medicalisation and resistance to pathologised
 narratives and curative practice. From this, the thesis explicates the
 role of the family in medicalisation – a perspective missing from studies
 focused exclusively on psychiatric materials. In exploring the role of the
 family and the medical practitioner, the thesis deconstructs pathologised
 understandings and attitudes,

 and reconstructs curative practice inside the clinic and the home. In
 doing so, it provides a nuanced understanding of the myriad forms of
 violence faced by queer individuals, as well as theoretical constructions
 to analyse the harms faced by the community.

 Additionally, the thesis contextualises the medicalisation of queerness
 within broader events. It engages with the legacy of colonial homophobia
 and the legal battles surrounding Section 377 of the Indian Penal Code.
 Moving beyond this, I argue that the interventions of the Emergency
 (1975-1977) paved the way for subsequent queer medicalisation. Similarly,
 the economic liberalisation of the 1990s provided access, support, and
 resources for an urban, English-speaking, queer elite who created
 publications that resisted medicalisation and

 criminalisation. Furthermore, the thesis reflects on the rise of Hindutva
 politics and the resurgence of medicalised narratives veiled in concerns
 about the nation. Through this queercentred approach, we see how histories
 of medicalisation must include accounts and narratives of resistance to
 pathologisation to understand how medicalisation extends beyond

 the clinic.

description: We explore the use of the stochastic resolution-of-the-identity (sRI) with the phaseless auxiliary-field quantum Monte Carlo (ph-AFQMC) method. sRI is combined with four existing local energy evaluation strategies in ph-AFQMC, namely (1) the half-rotated electron repulsion integral tensor (HR), (2) Cholesky decomposition (CD), (3) tensor hypercontraction (THC), or (4) low-rank factorization (LR). We demonstrate that HR-sRI achieves no scaling reduction, CD-sRI scales as $\mathcal O(N^3)$, and THC-sRI and LR-sRI scale as $\mathcal O(N^2)$, albeit with a potentially large prefactor. Furthermore, the walker-specific extra memory requirement in CD is reduced from $\mathcal O(N^3)$ to $\mathcal O(N^2)$ with sRI, while sRI-based THC and LR algorithms lead to a reduction from $\mathcal O(N^2)$ extra memory to $\mathcal O(N)$. Based on numerical results for one-dimensional hydrogen chains and water clusters, we demonstrated that, along with the use of a variance reduction technique, CD-sRI achieves cubic-scaling {\it without overhead}. In particular, we find for the systems studied the observed scaling of standard CD is $\mathcal O(N^{3-4})$ while for CD-sRI it is reduced to $\mathcal O(N^{2-3})$. Once a memory bottleneck is reached, we expect THC-sRI and LR-sRI to be preferred methods due to their quadratic-scaling memory requirements and their quadratic-scaling of the local energy evaluation (with a potentially large prefactor). The theoretical framework developed here should facilitate large-scale ph-AFQMC applications that were previously difficult or impossible to carry out with standard computational resources.

description: Providing students with learning opportunities based on real-life situations has beenfound to enhance student learning. With this aim, two Open University post-graduatecourses introduced collaborative activities modelled on workplace situations. Theactivities employed wikis: a lightweight, web-based collaborative authoringenvironment. The purpose of this research has been to investigate the role of a wiki insupporting the collaborative learning activities, and to assess how the wiki influencedstudent engagement with the activities.The dissertation draws data from the three presentations of Open University courses’56 wikis produced by almost 240 students. The base data includes wiki content andstudent discussions. Issues identified in the base data were further explored throughpost-course questionnaires and interviews. An iterative inductive qualitative analysiswas applied to analyse students' perceptions and experiences with the wikis. Activitytheory was used to place these within the context of the activities.The wikis enabled all student groups to author collaboratively the documents requiredby their courses. Writing the documents benefited the students because it prompteddiscussion and personal reflection; both of which many students reported as enhancingtheir learning. The students particularly valued the wiki’s role as a central repositorythat helped them achieve these two benefits. The research shows that wikis cansupport collaborative activities among students and lead to enhanced learningopportunities. The key findings suggest that a wiki’s simplicity enabled students toengage easily with the collaborative learning activities. However, a wiki’s lack ofinherent structure hindered their progress until they had worked out how to organisetheir use of the wiki. The insights from the research are presented as guidelines for educators intending toincorporate wiki supported collaborative learning activities into their courses. Theguidelines have two aims: first, to help educators facilitate speedy induction andparticipation of the students in the collaborative activities; second, to ensure the wiki isused effectively by students to increase their collaborative learning opportunities.

description: The effect of bond randomness on the spin-gapped ground state of the spin-1 bond-alternating antiferromagnetic Heisenberg chain is discussed. By using the loop cluster quantum Monte Carlo method, we investigate the stability of topological order in terms of the recently proposed twist order parameter [M. Nakamura and S. Todo: Phys. Rev. Lett. 89 (2002) 077204]. It is observed that the dimer phases as well as the Haldane phase of the spin-1 Heisenberg chain are robust against a weak randomness, though the valence-bond-solid-like topological order in the latter phase is destroyed by introducing a disorder stronger than the critical value.

Land‐based literacies in local naturecultures: Walking, reading, and storying the forests in rural Colombia
Creators: name: Posada, Tatiana Becerra

Publisher: name: Wiley
Year: 2024

description: Land‐based literacies scholars have worked to expand understandings of literacies to include often marginalized cultures who understand literacy as resulting from human and more‐than‐human relations. In this article, we contribute to this broadening of literacies with an analysis of how nature influences the meaning‐making practices of rural, subaltern communities in the Global South. Our inspiration stems from indigenous scholars who have advanced indigenous and relational epistemologies, seeking to bridge the nature/culture divide that remains prevalent in Western thinking. The central question that guides this article is: How are Land‐based literacies produced through the felt and sensed relationships with nature, history and culture in the Callemar community? Drawing on micro‐analysis of participant‐generated video data from two walks with Colombian youth and adults from the Callemar community, we illustrate ways naturecultures, specifically the assemblages of Land, collective memory and cultural practices, produce Land‐based literacies. We describe Land‐ walking, including forest‐ and creek‐crossing practices, as literacies that require reading and meaning‐making with the Land, and that which allow individuals to relate to other beings and thrive in the changing landscape of their rural community. Our description and discussion of Land‐based literacies in this rural community poses important implications for informing pluriversal literacies pedagogies that draw on local knowledges and contexts to make literacy learning more relevant and equitable. Furthermore, we describe the relevance of Land‐based literacies for sustainable stewardship of the Land during times of drastic environmental change.
Divesting power : EC comitology, GMO approvals, and the abdication of power by member states
Creators: name: Papić, Marko
Publisher: name: University of British Columbia
Year: 2010

description: Comitology procedure is the main decision-making mechanism of the European Community (EC) and from empirical records to date it appears to be an extremely efficient way of reaching consensus amongst the Member States. However, when attempting to reach a decision regarding the approval of Genetically Modified Organisms (GMO), the Comitology procedure consistently fails and Member States divest their decision-making responsibility to the Commission This paper analyzes the decision-making dynamics that lead to such a decision. It argues that the external pressures on the Member States and the Commission prevent deliberation and consensual solutions. Furthermore, the Comitology procedure itself exacerbates the conflict between states and prevents deliberative methods from being utilized. Member States strategically divest themselves from the responsibility to make decisions and "pass-the-buck" to the Commission. The paper concludes that the issue of GMO approvals should be taken out of Comitology as further failure will increase dissatisfaction of the European institutions and lead to more democratic deficit.

description: Wittmann Antal a m agyar reform kor egyik kiemelkedő egyénisége, Mosonmagyaróvár város neves polgára volt. Nem túlzás azt állítani, hogy korszakalkotó m unkásságot hagyott maga után. Az elmúlt 180 évben egyetlen gazdász sem végzett az Alma Materben, aki szellemi örökségéből ne hordana valamennyit a tarsolyában. Az agrártudományok és a termelési gyakorlat területén hatása európai léptékű. A városban utcát neveztek el róla. Em lékének az utódok szobor felállításával tisztelegnek. -------------- Antal Wittman, an outstanding personality of the Hungarian reformer age, was a notable citizen of Mosonmagyaróvár. It is no exaggeration to say that he left behind an epoch-making work. In the past 180 years no farmer left his Alma Mater without some of his spiritual inheritance in the bag. His influence in the fields of agricultural science and production methods can be measured on a European scale. A street is named after him in his city. His spiritual descendents raised his statue in his honor.

description: Predator–prey interactions heavily influence the dynamics of many ecosystems. An increasing body of evidence suggests that rapid evolution and coevolution can alter these interactions, with important ecological implications, by acting on traits determining fitness, including reproduction, anti-predatory defence and foraging efficiency. However, most studies to date have focused only on evolution in the prey species, and the predator traits in (co-)evolving systems remain poorly understood. Here, we investigated changes in predator traits after approximately 600 generations in a predator–prey (ciliate–bacteria) evolutionary experiment. Predators independently evolved on seven different prey species, allowing generalization of the predator's evolutionary response. We used highly resolved automated image analysis to quantify changes in predator life history, morphology and behaviour. Consistent with previous studies, we found that prey evolution impaired growth of the predator, although the effect depended on the prey species. By contrast, predator evolution did not cause a clear increase in predator growth when feeding on ancestral prey. However, predator evolution affected morphology and behaviour, increasing size, speed and directionality of movement, which have all been linked to higher prey search efficiency. These results show that in (co-)evolving systems, predator adaptation can occur in traits relevant to foraging efficiency without translating into an increased ability of the predator to grow on the ancestral prey type.
Initial test of a Bayesian approach to solar flare prediction

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: A test of a new Bayesian approach to solar flare prediction (Wheatland 2004a) is presented. The approach uses the past history of flaring together with phenomenological rules of flare statistics to make a prediction for the probability of occurrence of a large flare within an interval of time, or to refine an initial prediction (which may incorporate other information). The test of the method is based on data from the Geostationary Observational Environmental Satellites (GOES), and involves whole-Sun prediction of soft X-ray flares for 1976-2003. The results show that the method somewhat over-predicts the probability of all events above a moderate size, but performs well in predicting large events.
