title: The Role of HPV E7 in Maintenance of Cell Transformation
Creators: name: Basukala, Om
Publisher: name: The Open University
Year: 2019

description: A hallmark feature of cervical cancers caused by the Human Papillomavirus is the continued and high-level expression of viral oncoproteins. These viral oncoproteins play a significant role in induction of malignancy by targeting several critical cell control pathways. One of the potentially important elements in this process is phosphorylation of E7 by Casein Kinase II (CKII) which induces S-phase entry and modulates association with pRB and other pocket proteins. Phosphorylation of E7 has also been known to enhance E7’s ability to interact with other cellular targets and thereby increasing the ability of E7 to enhance cell proliferation and induce malignancy. However, there is little information on the importance of this site in E7, once the tumour cells have become fully transformed. To determine this, we have generated genome edited cell lines at CKII phospho-acceptor site of HPV-18 E7 in C4-1 cervical tumour derived cells using CRISPR/Cas9. We show that the HPV-18 E7 S32A/S34A mutation abolishes CKII phosphorylation. Genome edited cells with this mutation continue to proliferate but are more slow-growing than wild type cells, reach lower saturation densities and are susceptible to low nutrient conditions. The invasive ability of these cells is markedly reduced, partly due to downregulation of matrix metalloproteases (MMPs). Mechanistically, we find that phosphorylation of E7 plays a direct role in the ability of E7 to activate AKT signaling, which in turn is required for optimal levels of MMP secretion. Using proteomic analysis, we identify Vangl1, planar cell polarity protein, as a novel CKII phospho-dependent interactor of E7. The steady levels of Vangl1 are downregulated in genome edited cells and it co-operates with HPV-16 E7 in BRK cell transformation assays, indicating Vangl1 being important for E7 transforming activity. Finally, I also show that HPV-E7 interacts with PTPN21, a non-receptor tyrosine phosphatase, via c-terminal region of E7. The interaction leads to destabilization of PTPN21 by high-risk E7, suggesting a potential role of E7 in affecting post-translation modifications of its targets. Thus, HPV E7 continue to play an important role in maintenance of transformed phenotype and targeting E7 phosphorylation could be a potential therapeutic strategy in HPV-induced malignancy.

description: The 2$ν$-mediated force has a range of microns, well beyond the atomic scale. The effective potential is built from the t-channel absorptive part of the scattering amplitude and depends on neutrino properties on-shell. We demonstrate that neutral aggregate matter has a weak charge and calculate the matrix of six coherent charges for its interaction with definite-mass neutrinos. Near the range of the potential the neutrino pair is non-relativistic, leading to observable absolute mass and Dirac/Majorana distinction via different r-dependence and violation of the weak equivalence principle.

description: A set of objective bar-classification methods have been applied to the Ohio State Bright Spiral Galaxy Survey (Eskridge et al. 2002). Bivariate comparisons between methods show that all methods agree in a statistical sense. Thus the distribution of bar strengths in a sample of galaxies can be robustly determined. There are very substantial outliers in all bivariate comparisons. Examination of the outliers reveals that the scatter in the bivariate comparisons correlates with galaxy morphology. Thus multiple measures of bar strength provide a means of studying the range of physical properties of galaxy bars in an objective statistical sense.

description: We characterize the bundle properties for three different strains of \textit{B. subtilis} bacteria with various numbers of flagella. Our study reveals that, surprisingly, the number of bundles is independent of the number of flagella, and the formation of three bundles is always the most frequent case. We assume that this relates to the fact that different mutants have the same body length. There is no significant difference between the bundle width and length for distinct strains, but the projected angle between the bundles increases with the flagellar number. Furthermore, we find that the swimming speed is anti-correlated with the projected angle between the bundles, and the wobbling angle between the swimming direction and cell body increases with the number of flagella. Our findings highlight the impact of geometrical properties of bacteria such as body length and bundle configuration on their motility.

description: The study seeks to investigate the impact of major determinants influencing marketing potential and consumer’s willingness to pay for organic vegetables in Punjab, Pakistan. In this regard, two districts (Lahore and Toba Tek Singh) were selected purposively. Information was collected for main organic vegetables. Convenient sampling technique was used to collect data because limited numbers of respondents were available. A sample size of 50 organic farmers (25 from each district) and 50 consumers (25 from each district) was selected. Multivariate regression analysis was employed to identify and evaluate the effects of marketing potential (farmers) and consumer’s willingness to pay for organic vegetables in the study area. According to selected organic vegetable growers’ potential existed for the organic vegetables farming in the country and major variables influencing significantly the market potential for organic vegetables as income, price, no pesticide residues whereas hygienic food and more nutrients in the organic vegetables affecting insignificantly the market potential for organic vegetables in the study area. The relationship between dependent variable (demand for organic vegetables) and independent variables (income, hygienic food, price, pesticide residues and more nutrients in the organic vegetables) was estimating by using regression model. On the other hand, consumer survey was conducted in order to delineate the effect of consumer’s willingness to pay for organic vegetables in selected area. The findings of the research depicted that no synthetic pesticide residues, appearance and prices of organic vegetables influencing significantly the consumer’s willingness to pay for organic vegetables whereas quality, long shelf life and taste affecting insignificantly the consumer’s willingness to pay for organic vegetables in the study area. The price of the organic vegetables should be low that’s why every consumer will purchase organic vegetables instead of conventional vegetables. It should be assured by the government that there are no pesticide residues in the organic vegetables. Farming community may be motivated to produce quality seeds of organic vegetables. A pilot farming program should be initiated with joint involvement of public and private sectors.

description: No abstracts are to be cited without prior reference to the author.Functional redundancy is a community property thought to be contributing to ecosystem resilience. It is argued that trophic (or other) functional groups with more species have more linkages and opportunities to buffer variation in abundance of individual species. We explored this concept with a 30- year time series of data on 83 species sampled in the IBTS trawl survey.

description: We study how decoherence increases the efficiency with which we can simulate the quantum dynamics of an anharmonic oscillator, governed by the Kerr effect. As decoherence washes out the fine-grained subPlanck structure associated with phase-space quantum interference in the closed quantum system, open quantum dynamics can be more efficiently simulated using a coarse-grained finite-difference numerical integration. We tie this to the way in which decoherence recovers the semiclassical truncated Wigner approximation (TWA), which strongly differs from the exact closed-system dynamics at times when quantum interference leads to cat states and more general superpositions of coherent states. The regression in quadrature measurement statistics to semiclassical dynamics becomes more pronounced as the initial amplitude of the oscillator grows, with implications for the quantum advantage that might be accessible as system size grows in noisy quantum devices. Lastly, we show that this regression does not have the form of a convex noise model, such as for a depolarizing noise channel. Instead, closed quantum system effects interact with the open system effects, giving rise to distinct open system behavior.

description: We consider CP asymmetries in neutral $B$ meson decays to $η' K_S$, $ϕK_S$, and $K^+ K^- K_S$. We use SU(3) relations to estimate or bound the contributions to these amplitudes proportional to $V_{ub}^*V_{us}$. Such contributions induce a deviation of the $S_f$ terms measured in these time dependent CP asymmetries from that measured for $ψK_S$. For the $K^+ K^- K_S$ mode, we estimate the deviation to be of order 0.1. For the $η' K_S$ mode, we obtain an upper bound on this deviation of order 0.3. For the $ϕK_S$ mode, we have to add a mild dynamical assumption to the SU(3) analysis due to insufficient available data, yielding an upper bound of order 0.25. These bounds may improve significantly with future data. While they are large at present compared to the usually assumed Standard Model contribution, they are obtained with minimal assumptions and hence provide more rigorous tests for new physics. If measurements yield $|S_f-S_{ψK}|$ that are much larger than our bounds, it would make a convincing case for new physics.

description: The Dyson-Schwinger (DS) equations for a quantum field theory in $D$-dimensional space-time are an infinite sequence of coupled integro-differential equations that are satisfied exactly by the Green's functions of the field theory. This sequence of equations is underdetermined because if the infinite sequence of DS equations is truncated to a finite sequence, there are always more Green's functions than equations. An approach to this problem is to close the finite system by setting the highest Green's function(s) to zero. One can examine the accuracy of this procedure in $D=0$ because in this special case the DS equations are just a sequence of coupled polynomial equations whose roots are the Green's functions. For the closed system one can calculate the roots and compare them with the exact values of the Green's functions. This procedure raises a general mathematical question: When do the roots of a sequence of polynomial approximants to a function converge to the exact roots of that function? Some roots of the polynomial approximants may (i) converge to the exact roots of the function, or (ii) approach the exact roots at first and then veer away, or (iii) converge to limiting values that are unequal to the exact roots. In this study five field-theory models in $D=0$ are examined, Hermitian $ϕ^4$ and $ϕ^6$ theories and non-Hermitian $iϕ^3$, $-ϕ^4$, and $-i ϕ^5$ theories. In all cases the sequences of roots converge to limits that differ by a few percent from the exact answers. Sophisticated asymptotic techniques are devised that increase the accuracy to one part in $10^7$. Part of this work appears in abbreviated form in Phys.~Rev.~Lett.~{\bf 130}, 101602 (2023).

description: We perform N-body simulations on some of the most massive galaxies extracted from a cosmological simulation of hierarchical structure formation with total masses in the range $10^{12} M_{\odot} < M_{tot} < 3\times 10^{13} M_{\odot}$ from $4\geq z \geq 0$. After galactic mergers, we track the dynamical evolution of the infalling black holes (BHs) around their host's central BHs. From 11 different simulations, we find that, of the 86 infalling BHs with masses > $10^4 M_{\odot}$, 36 merge with their host's central BH, 13 are ejected from their host galaxy, and 37 are still orbiting at $z=0$. Across all galaxies, 33 BHs are kicked to a higher orbit after close interactions with the central BH binary or multiple, after which only one of them merged with their hosts. These orbiting BHs should be detectable by their anomalous (not Low Mass X-ray Binary) spectra. The X-ray luminosities of the orbiting massive BHs at z=0 are in the range $10^{28}-10^{43}$ $\mathrm{erg}~\mathrm{s}^{-1}$, with a currently undetectable median value of $10^{33}$ $\mathrm{erg}~\mathrm{s}^{-1}$. However, the most luminous $\sim$5\% should be detectable by existing X-ray facilities.

description: Having achieved remarkable improvement in access to basic education, India now faces an issue of low school progression beyond primary school. This paper attempts to investigate the schooling investment decisions by identifying the determinants of school progression in Andhra Pradesh state in India. The sequential logit model estimation using a panel data from cohort study which follows nearly 1,000 children from 2002 to 2013 sheds light on the dynamic aspect of schooling at different stages in primary and secondary education. The main findings are: (i) child’s reading and writing skills at 12 years old have persistent positive effects on school progression, (ii) job opportunities in terms of wage of unskilled workers show positive effects on school progression on boys while job opportunities in terms of presence of factory in locality show positive impact on school progression of both boys and girls, (iii) girls from households with less wealth and high dependency ratio, and the eldest girls in the household are more likely to drop out of school and marry at the age of 19.
title: Phylogenetics and Phylogeography in the Planktonic Diatom Genus Chaetoceros
Creators: name: De Luca, Daniele
Publisher: name: The Open University
Year: 2019

description: The initial aims of this thesis were to assess the systematics of the planktonic diatom genus Chaetoceros and the phylogeographic patterns of selected species in this genus across spatial and temporal scales. As expected in every experiment, some initial ideas have been pursued as they were; others have taken a different route and led to different questions. Consequently, the systematics of Chaetoceros has become a multigene phylogeny and a revision of the classical taxonomic scheme for the family Chaetocerotaceae (Chapter II). Then, the phylogeographic approach, initially meant as a Sanger sequencing of a few genes from specimens collected around the world, turned into the analysis of the C. curvisetus cryptic species complex by using an approach which combines haplotype networks and metabarcoding data (Chapter IV). The mapping of this complex against a temporal metabarcoding dataset (MareChiara, Gulf of Naples, IT) has become a story of concerted evolution and has been extended to different Chaetoceros species and supported by a single strain 18S-V4 high throughput sequencing (Chapter V). Amid these experiments, the potential of metabarcoding data for biological recording was explored and tested in the whole genus Chaetoceros to assess diversity and distribution (Chapter III). Such data were integrated with classical ones from public repositories and literature and used to produce, among the other results, distribution maps of Chaetoceros species.

description: We provide an initial framework regarding priorities for government programs to reduce the natural-disaster vulnerability of farm households in the Philippines. We begin with the likelihood that climate change will increase the probability of flooding, since rainfall is expected to both increase and be more concentrated (more storms). We then turn to a conceptual framework for understanding resilience at the household level and evidence from the PCED Social Protection Survey about coping strategies of farm households. The framework can be used to shed light on pros and cons of alternative public policies to reduce household vulnerability, including the role of discounting. In particular, we highlight the limited coping tools available to low-income households. This helps to strengthen the case for preventative polices that lower the probability and/or severity of damages. The inability of poor households to cope with increased exposure to risks, however, does not necessarily imply that social insurance programs should be expanded. Inasmuch as disaster risk management policies at the national level are typically without coherent foundations, we provide tentative indications of how the farm level risk-management framework can be expanded to the national level.

description: This paper investigates the adoption of VietGAHP, a set of guidelines for best practices in pig production, and evaluates impacts using quantitative and qualitative indicators. It tackles the following specific research questions: 1) What is the extent of adoption of VietGAHP among smallholder pig producers? 2) Is there a difference in performance between VietGAHP adopters and non-adopters? Outcomes from adoption and compliance with VietGAHP are assessed using reduction in mortality as a metric for efficacy. Cost-benefit comparisons are also made to illustrate economic outcomes as a measure of effectiveness. We employ statistical t-tests for mean comparison of outcomes between VietGAHP adopters and non-adopters and across exposed and control sites. Our study shows productivity gains from practice and behavioral changes elicited from adoption and compliance with VietGAHP outweigh the costs of doing so, at least at the household level. The observed economic and market incentives could boost the adoption of VietGAHP if these incentives are sustained with appropriate institutions in place. Scalability could be facilitated by exposure via demonstration effects. Peer-to-peer learning is an effective strategy in enhancing capacity for uptake. With exposure being strongly linked to uptake, regardless of gender of respondents, training opportunities for non-exposed groups are worthwhile to pursue.

The required inherent structures and transition states for the construction of disconnectivity graphs are found by combination of conjugate gradient and eigenvector-following methods. We show that it is possible to controllably induce new structures as well as reorder and stabilize existing structures that are characteristic of higher-lying minima. Moreover, it is shown that the selected structures can have experimentally relevant lifetimes.

description: We report strongly correlated electronic band structure calculations of the recently discovered double-layer high-temperature superconductor La$_3$Ni$_2$O$_7$ under pressure. Our calculations reveal dual nature of Ni-$d$ electrons with almost localized $d_{z^2}$ orbitals due to onsite Coulomb repulsion and very flat hybridization bands of Ni-$d_{x^2-y^2}$ and Ni-$d_{z^2}$ quasiparticles near the Fermi energy. We find that the quasiparticle effective mass are greatly enhanced by the Hund's rule coupling and their lifetimes are inversely proportional to the temperature, which explains the experimentally observed strange metal behavior in the normal state. We also find strong antiferromagnetic spin correlations of Ni-$d$ electrons, which may provide the pairing force of quasiparticles for the high-temperature superconductivity. These give a potential explanation of two key observations in experiment and connect the superconducting La$_3$Ni$_2$O$_7$ with cuprate high-temperature superconductors. The presence of flat bands and the interplay of orbital-selective Mott, Hund, and Kondo physics make La$_3$Ni$_2$O$_7$ a unique platform for exploring rich emergent quantum many-body phenomena in the future.

description: Social cohesion is an important determinant of community well-being, especially in times of distress such as disasters. This study investigates the phenomena of emergent social cohesion, which is characterized by abrupt, temporary and extensive social ties with the goal of sharing and receiving information regarding a particular event influencing a community. In the context of disasters, emergent social cohesion, enabled by social media usage, could play a significant role in improving the ability of communities to cope with disruptions in recent disasters. In this study, we employed a network reticulation framework to examine the underlying mechanisms influencing emergent social cohesion on social media while communities cope with disaster-induced disruptions. We analysed neighbourhood-tagged social media data (social media data whose users are tagged by neighbourhoods) in Houston, TX, USA, during Hurricane Harvey to characterize four modalities of network reticulation (i.e. enactment, activation, reticulation and performance) giving rise to emergent social cohesion. Our results show that, unlike regular social cohesion, communication history and physical proximity do not significantly affect emergent social cohesion. The results also indicate that weak social ties play an important role in bridging different social network communities, and hence reinforce emergent social cohesion. The findings can inform public officials, emergency managers and decision-makers regarding the important role of neighbourhood-tagged social media, as a new form of community infrastructure, for improving the ability of communities to cope with disaster disruptions through enhanced emergent social cohesion.

description: Many taxa show substantial differences in lifespan between the sexes. However, these differences are not always in the same direction. In mammals, females tend to live longer than males, while in birds, males tend to live longer than females. One possible explanation for these differences in lifespan is the unguarded X hypothesis, which suggests that the reduced or absent chromosome in the heterogametic sex (e.g. the Y chromosome in mammals and the W chromosome in birds) exposes recessive deleterious mutations on the other sex chromosome. While the unguarded X hypothesis is intuitively appealing, it had never been subject to a broad test. We compiled male and female longevity data for 229 species spanning 99 families, 38 orders and eight classes across the tree of life. Consistent with the unguarded X hypothesis, a meta-analysis showed that the homogametic sex, on average, lives 17.6% longer than the heterogametic sex. Surprisingly, we found substantial differences in lifespan dimorphism between female heterogametic species (in which the homogametic sex lives 7.1% longer) and male heterogametic species (in which the homogametic sex lives 20.9% longer). Our findings demonstrate the importance of considering chromosome morphology in addition to sexual selection and environment as potential drivers of sexual dimorphism, and advance our fundamental understanding of the mechanisms that shape an organism's lifespan.

description: Due to increasing scarcity of freshwater resources available for irrigated agriculture and escalating demand of food around the world, it will be necessary to produce more food with less water. Since, more irrigated land is devoted to rice than to any other crops in the world, wastage of water resource should be minimized (IRRI, 2003). Rice has been grown in low land areas under flooded conditions which required 3000-5000 liters of water for producing one kg rice. To address the problems of water scarcity, researchers had been looking for ways to decrease water consumption. One method to save water in irrigated rice cultivation is the intermittent drying of the rice fields instead of keeping them continuously flooded which is alternate wetting and drying irrigation (AWDI). For up scaling AWD, it is better to start with support for wider practices. Five case studies were conducted at Muktagacha, Phulpur, Trishal upazillas of Mymensingh district and Nalitabari and Nokla upazillas of Sherpur district in Bangladesh. It is seen that overall yield increased 11.7 percent by applying AWD where as it was 12.36 percent at DAE demonstration (DAE, 2010). It also can reduce irrigation use (29 to 34%) and pumping cost significantly. DAE demonstration experience through NATP showed that by using AWD, irrigation reduced 33 percent and cost reduced about 27.98 percent (DAE, 2010). BCR of applying AWD is 1.30 meaning is AWD application is beneficial for farmers. It can be concluded from FGD and IFDC’s research that: AWD demonstration saved amount of water, time and labour; yield of rice is higher in AWD plot than traditional practice. Finally undertaking massive dissemination of AWD programs through DAE staffs at the field level and print and electronic media such as TV, News paper, etc. are required.

Paradoxical Architecture : An Argument for the Anti-logic and the Absurd
Creators: name: Chang, Yau Ching Norain
Publisher: name: The University of British Columbia
Year: 2020

description: The project of paradoxical architecture aims to destabilize the current linear pragmatism architecture is bound by. We are experiencing an unprecedented rate of change in all aspects of our lives; climate change, technological development, commerce fluctuations, political landscapes and policy to name a few. In a world of constant changes, we must abandon the linear causal logic we deploy in our everyday decisions. I propose an alternative approach to logic; the anti-logic, a paradoxical way of thinking. Paradoxes are logic devices that can provide a new untouched landscape of opportunity in decision making strategies that exist in a space above the rational, in other words a surrational way. Rational logic is insufficient and therefore design needs to explore the surrational, the wildly unreasonable, the seemingly illogical and the self contradictory. Paradoxical Architecture applies the ethos of paradoxes and surrational logic to architectural approaches. This is a serial designed through surrationalism to create architectural paradoxes. And surprisingly, this approach may yield useful and pragmatic results.

description: Using canonical Monte Carlo simulations, we introduce a new numerical procedure for comparing the entropic exponents of polymers with different constraints and/or topologies. Setting up competitions between polymer segments which can exchange monomers according to their free energies, we obtain the universal exponents of partition functions, independently of any knowledge of the non-universal part. The method is successfully tested for closed polymer loops decorated with sliding rings. We also investigate the entropic exponents of loops with a fixed knot type, in which case we are limited by strong finite--size effects.

description: The double meson production in ultraperipheral heavy ions collisions is addressed, focusing on the particular case of rho-J/Psi from two-photon reactions. The cross section at photon level is obtained using distinct parameterizations for the gluon distribution on the light meson. The resulting estimates for the nuclear case are presented and discussed. As a by product, we estimate the double rho production cross section using the Pomeron-exchange factorization relations.

description: The emergent electric field (EEF) is a fictitious electric field acting on conduction electrons through the Berry phase mechanism. The EEF is generated by the dynamics of noncollinear spin configurations and becomes nonzero even in one dimension. Although the EEF has been studied for several one-dimensional chiral magnets, most of the theoretical studies were limited with respect to the strength and direction of the magnetic fields. Furthermore, the effect of edges of the system has not been clarified, whereas it can be crucial in nano- and micro-scale samples. Here, we perform a theoretical study on the momentum-frequency profile of the EEF in a one-dimensional chiral magnet while changing the strength and direction of the magnetic field for both bulk and finite-size chains with edges. As the bulk contributions, we find that the EEF is resonantly enhanced at the magnetic resonance frequencies; interestingly, the higher resonance modes are more clearly visible in the EEF response than in the magnetic one. Furthermore, we show that the EEF is amplified along with the solitonic feature of the spin texture introduced by the static magnetic field perpendicular to the chiral axis. We also show that the static magnetic field parallel to the chiral axis drives the EEF in the field direction, in addition to much slower drift motion in the opposite direction associated with the Archimedean screw dynamics, suggesting a DC electric current generation. As the edge contributions, we find additional resonance modes localized at the edges of the system that are also more clearly visible in the EEF response than the magnetic one. Our results reveal that the emergent electric phenomena in one-dimensional chiral magnets can be tuned by the magnetic field and the sample size, and provide not only a good probe of the magnetic resonances but also a platform for the applications to electronic devices.

description: In a diquark-diquark-antiquark picture of pentaquarks, we use two interpolating currents to calculate the mass of the recently measured $Ξ^{--}$ state in the framework of QCD sum rules. We show that, even though yielding similar values for $m_{Ξ^{--}}$ (and close to the experimental value), these currents differ from each other in what concerns the strength of the pole, convergence of the OPE and sensitivity to the continuum threshold parameter.

description: This paper estimates the shadow price of CO2 from burning maize straw in the Chinese agricultural sector and explores the policy implications for decision makers. Using a parametric quadratic directional distance function, we evaluate the production inefficiency and shadow prices of CO2 reduction for 7 major maize provinces in China from 1996-2014. The efficiency improves over time. In 2014, Shandong province ranks the top with full efficiency considering both economic and environmental impacts. The average efficiency will increase by 9% if conservation practices are adopted by assuming 10% decrease in yield and 50% decrease in burnt crop residue under conservation practices compared to conventional practices. The shadow price of CO2 from burning crop residue is estimated to range from 0-0.913 yuan/ha (or US$152/t) with an average of 0.45yuan/kg (or US$75/t). The downward slope of marginal abatement cost implies a rational of abating CO2 from the most polluted area. The abatement costs analysis imply that the whole society will benefit if the transaction cost of promoting adoption of conservation practices is less than 385 yuan/ha. This government offset would compensate farmers for yield reductions in favor of implementing conservation practices that would substantially reduce CO2 emissions.

description: Japanese laser interferometric gravitational wave detectors, TAMA300 and LISM, performed a coincident observation during 2001. We perform a coincidence analysis to search for inspiraling compact binaries. The length of data used for the coincidence analysis is 275 hours when both TAMA300 and LISM detectors are operated simultaneously. TAMA300 and LISM data are analyzed by matched filtering, and candidates for gravitational wave events are obtained. If there is a true gravitational wave signal, it should appear in both data of detectors with consistent waveforms characterized by masses of stars, amplitude of the signal, the coalescence time and so on. We introduce a set of coincidence conditions of the parameters, and search for coincident events. This procedure reduces the number of fake events considerably, by a factor $\sim 10^{-4}$ compared with the number of fake events in single detector analysis. We find that the number of events after imposing the coincidence conditions is consistent with the number of accidental coincidences produced purely by noise. We thus find no evidence of gravitational wave signals. We obtain an upper limit of 0.046 /hours (CL $= 90 %$) to the Galactic event rate within 1kpc from the Earth. The method used in this paper can be applied straightforwardly to the case of coincidence observations with more than two detectors with arbitrary arm directions.
