description: The COSY-11 collaboration has conducted experiments aiming at the determination of the excitation function and phase-space population of the p p --> p p eta reaction close to the kinematical threshold. The precise data obtained with the stochastically cooled proton beam of the cooler synchrotron COSY and the high resolution zero-degree magnetic spectrometer allowed for the observation of the significant deviations - in the shape of the excitation function and two-particle invariant masses - from the predictions based on the assumption that the reaction phase space is homogenously populated. Comparison of the shape of the excitation function for the p p --> p p eta and p p --> p p eta-prime reaction allows to distinquish in the model independent way an influence originating from the proton-proton and proton-eta interaction. For the comparison the full data set from experiments performed at COSY and other laboratories is used.

description: AbstractComplexes, where a doubly reduced CO22− (carbonite) ligand is spanned between a nickel(II) centre and a transition metal(II) ion (TM=Fe, Co, Zn) have been accessed. In non‐coordinating solvents the carbonite ligand exhibits a flexible coordination behaviour as observed by NMR spectroscopy and supported by DFT calculations. In particular the [Ni‐CO2‐Fe] representative replicates the respective entity in an intermediate formed during CO2‐conversion by the enzyme [Ni,Fe]‐CODH in many ways (structure, spectroscopic properties, reactivity). Our investigations reveal that transition metal ions reduce the reduction potential of the carbonite unit but increase its tendency to undergo C−O bond cleavage. This may explain the choice of an iron(II) ion instead of a s‐ or p‐block‐based Lewis acid as part of the active site.

description: We use a bang-bang optimal control model to derive a rule of thumb for an optimal management of invasive weeds, in terms of the marginal benefits and costs of various control actions. Instead of determining the size of infestation under an optimal surveillance measure, the rule specifies the types of land where an invasive weed should be first prevented from establishment, and under what conditions control should be initiated. The types of land are modeled via the heterogeneous vulnerability of land to the weed and likely infestation. This easy-to-use rule is applied to determine how hawkweed should be controlled in Australia, across three potential control strategies: containment, eradication and no action. We investigate this rule-of-thumb in both deterministic and stochastic settings. With uncertainty, when calculating the threshold of when and how to act, we take into account the fact that delaying a control action will incur not only larger damage and a potentially larger spread but also a higher cost from uncertainty in the spread of the weed itself. The land value threshold is thus given by the unit cost of keeping a weed off a parcel of land times the difference between the interest rate and the current weed spread rate plus the effect of uncertainty. An application to hawkweed in Australia is provided. The rule specifies that hawkweed should be immediately eradicated in all types of agricultural lands they currently occupy where the potential damage is larger than 15AUD/ha/year. This generates a full eradication strategy under broad parameter values. Though the cost of removing hawkweeds is significant, it is overwhelmed by the damage if Hawkweeds spread to higher value agricultural land.
Improving the Efficiency of Self-Supervised Adversarial Training through Latent Clustering-based Selection

description: Compared to standard learning, adversarially robust learning is widely recognized to require a much larger training dataset. Recent works utilize external or synthetically generated unlabeled data in adversarial training using self-supervised learning. Despite achieving enhanced robustness, these methods typically require a considerable amount of additional data, leading to substantial memory consumption and convergence time. To address the space and computational challenges, we propose a novel Latent Clustering-based Selection scheme (LCS) to strategically select a small core subset of unlabeled data critical for obtaining better robustness. In particular, our method prioritizes selecting unlabeled data that are close to the model’s decision boundary, while balancing the ratio between the boundary and the remaining data points to avoid overfitting. Our experiments show that when incorporated into self-supervised adversarial training, our LCS scheme can significantly reduce the memory and time complexities while achieving comparable model robustness.

description: We have measured the angular and spatial clustering of 671 K<18.40, R-K>5 Extremely Red Objects (EROs) from a 0.98 square degree sub-region of the NOAO Deep Wide-Field Survey (NDWFS). Our study covers nearly 5 times the area and has twice the sample size of any previous ERO clustering study. The wide field of view and BwRIK passbands of the NDWFS allow us to place improved constraints on the clustering of z=1 EROs. We find the angular clustering of EROs is slightly weaker than in previous measurements, and w(1')=0.25+/-0.05 for K<18.40 EROs. We find no significant correlation of ERO spatial clustering with redshift, apparent color or absolute magnitude, although given the uncertainties, such correlations remain plausible. We find the spatial clustering of K<18.40, R-K>5 EROs is well approximated by a power-law, with r_0=9.7+/-1.1 Mpc/h in comoving coordinates. This is comparable to the clustering of 4L* early-type galaxies at z<1, and is consistent with the brightest EROs being the progenitors of the most massive ellipticals. There is evidence of the angular clustering of EROs decreasing with increasing apparent magnitude, when NDWFS measurements of ERO clustering are combined with those from the literature. Unless the redshift distribution of K>20 EROs is very broad, the spatial clustering of EROs decreases from r_0=9.7+/-1.1 Mpc/h for K<18.40 to r_0=7.5 Mpc/h for K>20 EROs.

description: The focus of this report is to report choice modelling experiments that have tested the consistency of values across differently scoped dimensions of an environmental asset. The case study involved the Great Barrier Reef (GBR) in Australia, where a key policy question is to identify if protection values for one part of the reef can be transferred to different sections and scaled from local case studies to the whole reef area without adjustment. The study involved 12 split-samples in three CM experiments to assess values for the whole GBR, a regional section of the GBR and a local reef area while controlling for variations across populations, the scope of the choice tasks, and survey formats. The results demonstrate that issues of geographic scope and scale remain challenging in CM experiments. Contrary to expectations, the proportional values for different regions of the GBR remained consistent when geographic scope and scale increased, while absolute values declined. This was despite substantial efforts in designing and presenting the surveys to define the amenity of interest to respondents. The results indicate that it is difficult to identify single unit values for an environmental amenity that can be easily transferred and extrapolated across geographic regions and scales. However, there may be good theoretical reasons why marginal values for specific areas of interest in the GBR have much higher protection values, which then decline as larger and more general areas are considered.

description: The goal of this paper is speaker diarisation of videos collected 'in the wild'. We make three key contributions. First, we propose an automatic audio-visual diarisation method for YouTube videos. Our method consists of active speaker detection using audio-visual methods and speaker verification using self-enrolled speaker models. Second, we integrate our method into a semi-automatic dataset creation pipeline which significantly reduces the number of hours required to annotate videos with diarisation labels. Finally, we use this pipeline to create a large-scale diarisation dataset called VoxConverse, collected from 'in the wild' videos, which we will release publicly to the research community. Our dataset consists of overlapping speech, a large and diverse speaker pool, and challenging background conditions.
description: The dataset will be available for download from http://www.robots.ox.ac.uk/~vgg/data/voxceleb/voxconverse.html . The development set will be released in July 2020, and the test set will be released in October 2020

description: We give empirical welfare results for global greenhouse gas emission control, using the first multiparty model to combine tax-versus-trading under uncertainties with revenue recycling. Including multiple parties greatly reduces the welfare advantage of an emissions tax over emissions (permit) trading in handling abatement-cost uncertainties, from that shown by existing, single-party literature. But a tax has a different, much bigger advantage, from better handling uncertainties in business-as-usual emissions. Either mechanism's free emissions share, from tax thresholds or free permits, which lowers its possible welfare gain from revenue recycling, may however dominate any tax-versus-trading advantage. Moreover, political and practical constraints, such as the political unacceptability of no free emissions, the institutional unavailability of efficient emissions tax thresholds, and the unpopularity of recycling revenue as conventional tax cuts, make ideal welfare maximisation a poor guide for mechanism choice; and at optimal prices, trading currently tends to outperform taxation.
The Local Instability of Steady Astrophysical Flows with non Circular Streamlines with Application to Differentially Rotating Disks with Free Eccentricity

Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: We carry out a general study of the stability of astrophysical flows that appear steady in a uniformly rotating frame. Such a flow might correspond to a stellar pulsation mode or an accretion disk with a free global distortion giving it finite eccentricity. We consider perturbations arbitrarily localized in the neighbourhood of unperturbed fluid streamlines.When conditions do not vary around them, perturbations take the form of oscillatory inertial or gravity modes. However, when conditions do vary so that a circulating fluid element is subject to periodic variations, parametric instability may occur. For nearly circular streamlines, the dense spectra associated with inertial or gravity modes ensure that resonance conditions can always be satisfied when twice the period of circulation round a streamline falls within. We apply our formalism to a differentially rotating disk for which the streamlines are Keplerian ellipses, with free eccentricity up to 0.7, which do not precess in an inertial frame. We show that for small $e,$ the instability involves parametric excitation of two modes with azimuthal mode number differing by unity in magnitude which have a period of twice the period of variation as viewed from a circulating unperturbed fluid element. Instability persists over a widening range of wave numbers with increasing growth rates for larger eccentricities. The nonlinear outcome is studied in a follow up paper which indicates development of small scale subsonic turbulence.

description: In the New Economy, the network is considered as more important than the firm itself. In this paper the focus is on chain networks which include vertical networks among chain members, horizontal networks with peers, and networking with third parties. Networks have an important role in the diffusion and adoption of innovations, thus they are the locus of innovation. While previous research focused on the firm, we contribute to the understanding of innovations in chain networks, i.e. we investigate the innovation capacity in vertical networks and how networking with peers and third parties is influencing the innovation capacity of the vertical network. We propose that there is a positive relationship between the network connections the direct chain partners have with peers and third parties and the innovation capacity of the vertical network. Data were collected from 90 direct agrifood chains in the traditional food sector. Cluster analysis suggested three clusters of chains corresponding to three distinct levels of innovation capacity: low, medium and high. Via descriptive analysis and binary logistic regression the influence of networking with peers and third parties on the innovation capacity of the vertical network was investigated. Our results confirm our proposition. However, we found that the chain partners are either horizontally or vertically networking for innovation. Nevertheless, more networking within the chain and with peers and third parties is linked to higher levels of innovation capacity. Consequently, our study adds to the research in the field of the New Economy by deepening the understanding of how innovation capacity is developed in vertical networks. We can confirm that the network is very important for the development and implementation of innovations and that the innovation capacity of one firm is linked to the innovation capacity of its chain partners. For future research we propose to investigate the link between networking for innovation and types of innovation which can be achieved. Further, future research should explore further inter-organizational links in the chain network and explore wider networks than the direct chain.

description: This paper presents the results of a choice modeling survey of households in Queensland to assess values for reductions in national greenhouse emissions by 2020. The study is novel in two main ways. First, labeled alternatives were used to assess whether the types of broad management options for reducing net emissions (green power, alternative technologies or carbon capture) are significant in understanding preferences for reducing emissions. Second, the importance of the level and type of uncertainty involved in reductions is tested. They include (1) the uncertainty of achieving emissions reduction and (2) the uncertainty of international participation as the percentage of total global emissions covered by international agreements. The results of this survey identified how choice responses vary when the level of uncertainty associated with emissions reduction options are included within choice alternatives.

We aim at a fairly general description of rendezvous numbers in a metric space by using systematically the potential theoretic approach. In particular, we generalize and explain results on invariant measures, hypermetric spaces and maximal energy measures, when showing how more general proofs can be found to them.

Effect of clustering on the orientational properties of a fluid of hard right isosceles triangles

Year: 2022
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Recent studies have shown the fluid of hard right triangles to possess fourfold and quasi-eightfold (octatic) orientational symmetries. However, the standard density-functional theory for two-dimensional anisotropic fluids, based on two-body correlations, and an extension to incorporate three-body correlations, fail to describe these symmetries. To explain the origin of octatic symmetry we postulate strong particle clustering as a crucial ingredient. We use Scaled Particle Theory to analyze four binary mixtures of hard right triangles and squares, three of them being extreme models for a one-component fluid, where right triangles can exist as monomeric entities together with triangular dimers, square dimers or square tetramers. Phase diagrams exhibit a rich phenomenology, with demixing and three-phase coexistences. More important, under some circumstances the orientational distribution function of triangles has equally high peaks at relative particle angles 0, $π/2,$ and $π$, signalling fourfold, tetratic order, but also secondary peaks located at $π/4$ and $3π/4$, a feature of eightfold, octatic order. Also, we extend the binary mixture model to a quaternary mixture consisting of four types of clusters: monomers, triangular and square dimers, and square tetramers. This mixture is analyzed using Scaled Particle Theory under the restriction of fixed cluster fractions. Apart from the obvious tetratic phase promoted by tetramers, we found that, for certain cluster compositions, the total orientational distribution function of monomers can exhibit quasi-eightfold (octatic) symmetry. The study gives evidence on the importance of clustering to explain the peculiar orientational properties of liquid-crystal phases in some two dimensional fluids.

Molecular regulators of apical/basal polarity during mammary epithelial morphogenesis and invasive tumor progression
Creators: name: Somasiri, Aruna Mahendra
Publisher: name: University of British Columbia
Year: 2009

description: During breast cancer progression, the mammary gland undergoes architectural changes marked by a disruption of epithelial apical/basal polarity. In infiltrating lobular carcinomas (ILC) this disruption is marked by a loss of adherens (AJ) and tight (TJ) junctions. However, in the more prevalent infiltrating ductal carcinomas (IDC), AJ often remain while TJ are lost or disorganized. Thus, the loss of TJ polarity may be an important component of invasive, cancer progression. Because TJs and the basement membrane (BM) are critical components of apical and basal polarity, I chose to study the importance of polarity changes during breast cancer progression. To identify the molecular regulators of TJ dynamics in the normal breast I used a 3D hierarchical model of mammary epithelial cell morphogenesis in vitro. In this hierarchy, functional AJ were initially formed and then the TJs were formed. These TJs were not polarized and the TJ scaffolding protein ZO-1 co-localized with the AJ protein β-catenin at AJs. Upon addition of a soluble BM, ZO-1 was released from the AJ complex and the TJ complex migrated apically. This apical polarization of the TJ was mediated, at least in part, by interactions of the α6β4 integrin with laminin in the BM. The ETV6-NTRK3 (EN) fusion protein is expressed in secretory breast carcinomas (SBC) and two proteins, Podocalyxin and the Integrin-linked kinase (ILK), are involved in modulating cell-cell junctions. Thus, I examined the effects of these three genes on cell polarity. Forced expression of EN in normal epithelial cells induced cell proliferation without affecting TJ polarity, further explaining the non-metastatic phenotype of SBC. Podocalyxin was highly expressed in a subset of ductal tumors that become metastatic. When podocalyxin was expressed in a well-differentiated breast cancer cell line, TJs and polarity were perturbed, resulting a phenotype similar to IDC. When ILK was expressed in normal epithelial cells, they completely lost both TJs and AJs initiating an epithelial to mesenchymal transformation, hence an ILC phenotype. These data suggest that the establishment of polarized TJs is critical for normal mammary epithelial architecture, while changes to this architecture, at least in part, contribute to invasive breast tumor progression.

description: The focus of this report is to test if protection values at a particular GBR site may be easily transferred to other case studies of interest in the region. The research involved valuing three local case studies in the GBR and testing how values were consistent across site and population characteristics. The sites were chosen to reflect substantial heterogeneity in extent, ecological composition and condition, while values were assessed for both local and distant populations. The results are encouraging, indicating that although significant heterogeneity was identified with the mixed logit models, values were robust to various site and population differences. No significant difference in protection values between the three local case studies could be identified, and there was no significant difference in values between the local population and the Brisbane population. However, some evidence for distance effects was identified for the Brisbane population, with closer sites valued more highly. As well, potential losses were valued more highly (in absolute terms) than potential gains. The implication of these results is that protection values are likely to be higher for closer reef areas with risks of losses than these with opportunities for improvements.

description: This paper investigates regional cluster of organic grassland farms with respect to technical efficiency. The data-base consists of organic grassland and mixed farms in Germany from 1994/95 to 2005/06. In a first step five inputs and one output are analyzed by means of a stochastic frontier production function, allowing for heteroscedasticity and technical effects. The selection of determinants of technical efficiency is based on location theory. Since organic farming has regional centers, technical efficiency (TE) of organic farms is found to be affected by regional variables (such as agglomeration effects). In a second step we identified regional clusters of organic farms and analyzed the technical efficiency of the regional clusters. The results show that organic farms in distinct regions show different efficiency performance - suggesting that there are agglomeration and urbanization effects in the organic market.

description: A number of studies have examined the effects of distance decay and the influence it might have on both use and non-use values. However, the relationship between environmental values and distance effects is less clear cut when iconic or special assets are involved. In this report, the effects of distance decay on protection values of the Great Barrier Reef in Australia are explored using two split sample choice experiments. The results suggest that the Townsville (local) population had larger use values than the Brisbane (distant) population. However, for iconic resources, where perceptions of responsibility, substitutes and information are reasonably consistent across population groups, non-use values remain constant across spatially different population groups.

description: Synthetic photonic lattice with temporally controlled potentials is a versatile platform for realizing wave dynamics associated with physical areas of optics and quantum physics. Here, discrete optics in one-dimensionally synthetic photonic lattice is investigated systematically, in which the light behavior is highly similar to those in evanescently coupled one-dimensional discrete waveguides. Such a synthetic dimension is constructed with position-dependent periodic effective gauge fields based on Aharonov-Bohm effect arising from the phase accumulations of the fiber loops. By tuning the phase accumulations and coupling coefficient of the coupler, the band translation and gap property can be modulated which further results in the impulse and tailored Gaussian wave packet responses as well as Talbot recurrences. In addition, Bloch oscillations and Anderson localization can also be obtained when the phase accumulations are linearly changed and weakly modulated in random, respectively. The periodic effective gauge fields configuration in our protocol enables SPL to be a research platform for one-dimensional dynamically modulated elements or even non-Hermitian waveguides.

description: The evolution of Ca$_{2-x}$Na$_{x}$CuO$_{2}$Cl$_{2}$ from Mott insulator to superconductor was studied using angle-resolved photoemission spectroscopy. By measuring both the excitations near the Fermi energy as well as non-bonding states, we tracked the doping dependence of the electronic structure and the chemical potential with unprecedented precision. Our work reveals failures in the conventional quasiparticle theory, including the broad lineshapes of the insulator and the apparently paradoxical shift of the chemical potential within the Mott gap. To resolve this, we develop a model where the quasiparticle is vanishingly small at half filling and grows upon doping, allowing us to unify properties such as the dispersion and Fermi wavevector with the behavior of the chemical potential.

description: Tunable diode laser induced fluorescence (TDLIF) measurements are discussed and quantitatively evaluated for nitrogen admixtures in argon plasma under the influence of a strong magnetic field. TDLIF measurements were used to evaluate light-transport properties in a strongly magnetized optically thick argon/nitrogen plasma under different pressure conditions. Therefore, a coupled system of rate balance equations was constructed to describe laser pumping of individual magnetic sub-levels of $\mathrm{2p_8}$ state through frequency-separated sub-transitions originating from $\mathrm{1s_4}$ magnetic sub-levels. The density distribution (alignment) of $\mathrm{2p_8}$ multiplet was described by balancing laser pumping with losses including radiative decay, transfer of excitation between the neighboring sub-levels in the $\mathrm{2p_8}$ multiplet driven by neutral collisions (argon and nitrogen) and quenching due to electron and neutral collisions. Resulting $\mathrm{2p_8}$ magnetic sub-level densities were then used to model polarization dependent fluorescence, considering self-absorption, which could be directly compared with polarization-resolved TDLIF measurements. This enables to estimate the disalignment rate constant for the $\mathrm{2p_8}$ state due to collisions by molecular nitrogen. A comparison to molecular theory description is given providing satisfactory agreement. The presented measurement method and model can help to describe optical emission of argon and argon-nitrogen admixtures in magnetized conditions and provides a basis for further description of optical emission spectra in magnetized plasmas.

description: Using the example of the MAB Biosphere Preserve “Mittlere Elbe”, this article demonstrates how an “optimal” land-use pattern – a pattern aimed at combining ecological, economic and social objectives in an adequate way – can be determined. The focus is on the definition of alternative nature conservation approaches, the scenario technique, the definition of landscape functions, the utility analysis and the adaptive conjoint analysis. In addition, the authors demonstrate which quantitative methods can be used to obtain the information needed for utility and conjoint analyses on the ecological and economic effects of the conservation scenarios as well as on the weighting of the landscape functions, and how they can be integrated. Finally, it is shown that the conflict between ecological and economic objectives cannot only be reduced by a regional differentiation of the extent of resource protection – as shown in the literature –, but also by a spatial variation of the type of environment conservation.

description: Investment decisions are, as a rule, characterized by uncertainty, irreversibility and flexibility. Simple net present value calculations will not account for these features. In many situations even flexible investment planning with decision trees, which represents the most advanced method of traditional investment appraisal, does not have the capacity to solve practical decision problems adequately. One handicap is a realistic and manageable representation of stochastic variables. It has long been known that stochastic simulation procedures offer a nearly unlimited capacity to represent distributions and stochastic processes. However, a standard simulation will not allow for the consideration of flexibility. The problem is that with a simple forward moving simulation of stochastic paths it is not clear at potential investment dates whether waiting or investing represents the optimal strategy. In this paper we show how stochastic simulation procedures can be integrated successfully into a backward recursive programming approach. The resulting modus operandi can be called “Bounded Recursive Stochastic Simulation” (BRSS). We use this efficient combination of simulation and dynamic programming to answer the question whether farmers should buy sales contracts which guarantee fixed prices for rye in the future. The results of the model affirm the importance of uncertainty and flexibility for investment decisions. They also show that the actual conditions offered by the wholesale buyer are not economically attractive for farmers, unless they are extremely risk averse. Thus, model results coincide with the empirical evidence that farmers do not enter these contracts.

description: We investigate the effect of school closure and subsequent reopening on the transmission of COVID-19, by considering Denmark, Norway, Sweden, and German states as case studies. By comparing the growth rates in daily hospitalisations or confirmed cases under different interventions, we provide evidence that the effect of school closure is visible as a reduction in the growth rate approximately 9 days after implementation. Limited school attendance, such as older students sitting exams or the partial return of younger year groups, does not appear to significantly affect community transmission. A large-scale reopening of schools while controlling or suppressing the epidemic appears feasible in countries such as Denmark or Norway, where community transmission is generally low. However, school reopening can contribute to significant increases in the growth rate in countries like Germany, where community transmission is relatively high. Our findings underscore the need for a cautious evaluation of reopening strategies that ensure low classroom occupancy and a solid infrastructure to quickly identify and isolate new infections.
