description: With the rapid growth of financial services, fraud detection has been a very important problem to guarantee a healthy environment for both users and providers. Conventional solutions for fraud detection mainly use some rule-based methods or distract some features manually to perform prediction. However, in financial services, users have rich interactions and they themselves always show multifaceted information. These data form a large multiview network, which is not fully exploited by conventional methods. Additionally, among the network, only very few of the users are labelled, which also poses a great challenge for only utilizing labeled data to achieve a satisfied performance on fraud detection. To address the problem, we expand the labeled data through their social relations to get the unlabeled data and propose a semi-supervised attentive graph neural network, namedSemiGNN to utilize the multi-view labeled and unlabeled data for fraud detection. Moreover, we propose a hierarchical attention mechanism to better correlate different neighbors and different views. Simultaneously, the attention mechanism can make the model interpretable and tell what are the important factors for the fraud and why the users are predicted as fraud. Experimentally, we conduct the prediction task on the users of Alipay, one of the largest third-party online and offline cashless payment platform serving more than 4 hundreds of million users in China. By utilizing the social relations and the user attributes, our method can achieve a better accuracy compared with the state-of-the-art methods on two tasks. Moreover, the interpretable results also give interesting intuitions regarding the tasks.

The non-Abelian feature of parton energy loss in energy dependence of jet quenching in high-energy heavy-ion collisions

Year: 2004
Subjects: subject: Nuclear Theory (nucl-th)

subject: FOS: Physical sciences

description: One of the non-Abelian features of parton energy loss is the ratio $ΔE_g/ΔE_q=9/4$ between gluon and quark jets. Since jet production rate is dominated by quark jets at high $x_T=2p_T/\sqrt{s}$ and by gluon jets at low $x_T$, high $p_T$ hadron suppression in high-energy heavy-ion collisions should reflect such a non-Abelian feature. Within a leading order perturbative QCD parton model that incorporates transverse expansion and Woods-Saxon nuclear distribution, the energy dependence of large $p_T\sim 5-20$ GeV/$c$ hadron suppression is found to be sensitive to the non-Abelian feasture of parton energy loss and could be tested by data from low energy runs at RHIC or data from LHC.

description: The phase behavior of fluids near weakly attractive substrates is studied by computer simulations of the coexistence curve of a Lennard-Jones (LJ) fluid confined in a slitlike pore. The temperature dependence of the density profiles of the LJ fluid is found to be very similar to the behavior of water near hydrophobic surfaces (Brovchenko et al. J.Phys.: Cond.Matt. v.16, 2004). A universal critical behavior of the local order parameter, defined as the difference between the local densities of the coexisting liquid and vapor phases at some distance z from the pore walls, Deltarho(z) = (rho_l(z) - rho_v(z))/2, is observed in a wide temperature range and found to be consistent with the surface critical behavior of the Ising model. Near the surface the dependence of the order parameter on the reduced temperature tau = (T_c - T)/T_c obeys a scaling law ~ tau^(beta_1) with a critical exponent beta_1 of about 0.8, corresponding to the ordinary surface transition. A crossover from bulk-like to surface-like critical behavior with increasing temperature occurs, when the correlation length is about half the distance to the surface. Relations between the ordinary and normal transitions in Ising systems and the surface critical behavior of fluids are discussed.

The church of Agios Georgios in Akraifnio used to be the main church of the village. It was abandoned when the new homonymous church was built. Some locals, who were interested in their village’s history, focused their efforts on the restoration of this monument. The need for a legal framework that would ensure that all this effort would be turned into a substantial action to protect and promote the monument soon arose, as the current legal framework does not encourage any voluntary initiative.

The Roman Dodecahedron : A Comprehensive Scientific Inquiry
Creators: name: Ishihara, Masashi
Publisher: name: Zenodo
Year: 2025

description: The Roman dodecahedron, an enigmatic artifact dating from the 2nd to 3rd centuries CE, has puzzled archaeologists and historians for centuries. Found primarily in the northern territories of the Roman Empire, it is characterized by twelve pentagonal faces, each featuring circular holes of varying diameters, and small spherical protrusions at its vertices. This paper explores its possible functions, focusing on the hypothesis that it was used as a time-measuring device, particularly in military contexts. Through an extensive review of archaeological evidence, metallurgical analysis, and experimental studies, we assess its potential role in Roman frontier logistics, military operations, and technological innovation.

description: Encyclopedic knowledge graphs, such as Wikidata, host an extensive repository of millions of knowledge statements. However, domain-specific knowledge from fields such as history, physics, or medicine is significantly underrepresented in those graphs. Although few domain-specific knowledge graphs exist (e.g., Pubmed for medicine), developing specialized retrieval applications for many domains still requires constructing knowledge graphs from scratch. To facilitate knowledge graph construction, we introduce WAKA: a Web application that allows domain experts to create knowledge graphs through the medium with which they are most familiar: natural language.

description: En este articulo analizamos las ganancias potenciales en bienestar asociadas al establecimiento de un mercado de derechos sobre aqua para uso agricola. Frente a la tradicional asignacion administrativa del recurso, los intercambios voluntarios de derechos entre los distintos sectores agricolas confieren la flexibilidad necesaria para hacer frente a las sequias ciclicas que caracterizan el regimen hidrico de Baleares. Para simular el funcionamiento del mercado propuesto hemos contruido un Modelo de Equilibrio General Computable (CGE) que intenta aproximarse a la estructura economica y a la problematica hidrologica de Baleares. Los resultados obtenidos muestran como una reasignacion de los derechos sobre aqua entre los distinctos cultivos, puede, en primer lugar, aumentar la eficiencia asignativa y en el uso del recurso y, en segundo lugar, producir efectos ergionales positivos en terminos de empleo y renta agricola. Con todo ello, pretendemos mostrar, ademas, las posibilidades de aplicacion de los modelos de equilibrio general en el campo de la gestion hidraulica...We analyse the potential welfare gains of an agricultural water rights market. Compared to the traditional administrative allocation, the voluntary water exchanges between different agricultural sectors allow enough flexibility to cope with the cyclical draughts characteristic of the Balearic hydrological regime. To simulate the market an Applied General Equilibrium (CGE) model for the Balearic Islands is used. The simulations show that the reallocation of water rights between the different crops makes the use and allocation of the resource more efficient. Moreover, the regional effects in terms of agricultural income and employment are positive. In broad terms, this paper of illustration of the applicability of the general equilibrium models to the water management.

description: We report experimental results on the three dimensional Lagrangian acceleration in highly turbulent flows. Tracer particles are tracked optically using four silicon strip detectors from high energy physics that provide high temporal and spatial resolution. The components of the acceleration are shown to be statistically dependent. The probability density function (PDF) of the acceleration magnitude is comparable to a log-normal distribution. Assuming isotropy, a log-normal distribution of the magnitude can account for the observed dependency of the components. The time dynamics of the acceleration components is found to be typical of the dissipation scales whereas the magnitude evolves over longer times, possibly close to the integral time scale.

description: The acoustic vibrations of single monomers and dimers of gold nanoparticles were investigated by measuring for the first time their ultra-low frequency micro-Raman scattering. This experiment provides access not only to the frequency of the detected vibrational modes, but also to their damping rate, which is obscured by inhomogeneous effects in measurements on ensembles of nano-objects. This allows a detailed analysis of the mechanical coupling occurring between two close nanoparticles (mediated by the polymer surrounding them) in the dimer case. Such coupling induces the hybridization of the vibrational modes of each nanoparticle, leading to the appearance in the Raman spectra of two ultra-low frequency modes corresponding to the out-of-phase longitudinal and transverse (with respect to the dimer axis) quasi-translations of the nanoparticles. Additionally, it is also shown to shift the frequency of the quadrupolar modes of the nanoparticles. Experimental results are interpreted using finite-element simulations, which enable the unambiguous identification of the detected modes and, despite the simplifications made, lead to a reasonable reproduction of their measured frequencies and quality factors. The demonstrated feasibility of low frequency Raman scattering experiments on single nano-objects opens up new possibilities to improve the understanding of nanoscale vibrations, this technique being complementary with single nano-object time-resolved spectroscopy as it gives access to different vibrational modes.
Chiral Anomalies via Classical and Quantum Functional Methods

description: In the quantum path integral formulation of a field theory model an anomaly arises when the functional measure is not invariant under a symmetry transformation of the Lagrangian. In this paper, generalizing previous work done on the point particle, we show that even at the classical level we can give a path integral formulation for any field theory model. Since classical mechanics cannot be affected by anomalies, the measure of the classical path integral of a field theory must be invariant under the symmetry. The classical path integral measure contains the fields of the quantum one plus some extra auxiliary ones. So, at the classical level, there must be a sort of "cancellation" of the quantum anomaly between the original fields and the auxiliary ones. In this paper we prove in detail how this occurs for the chiral anomaly.

description: Adaptive workloads can change on--the--fly the configuration of their jobs, in terms of number of processes. In order to carry out these job reconfigurations, we have designed a methodology which enables a job to communicate with the resource manager and, through the runtime, to change its number of MPI ranks. The collaboration between both the workload manager---aware of the queue of jobs and the resource allocation---and the parallel runtime---able to transparently handle the processes and the program data---is crucial for our throughput-aware malleability methodology. Hence, when a job triggers a reconfiguration, the resource manager will check the cluster status and return an action: an expansion, if there are spare resources; a shrink, if queued jobs can be initiated; or none, if no change can improve the global productivity. In this paper, we describe the internals of our framework and how it is capable of reducing the global workload completion time along with providing a smarter usage of the underlying resources. For this purpose, we present a thorough study of the adaptive workloads processing by showing the detailed behavior of our framework in representative experiments and the low overhead that our reconfiguration involves.

description: En France, prendre trois repas par jour constitue une caractéristique culturelle importante qui s’est développée au 19ème siècle sur le modèle bourgeois. Nous avons cherché à tester si ce modèle prévaut toujours et à analyser dans quelle mesure la structure familiale, le sexe, le revenu et la migration sont associés à la fréquence des repas. Cette recherche s’appuie sur l’analyse transversale des données recueillies en 2010 auprès de la cohorte SIRS (Santé, inégalités, ruptures sociales) sur un échantillon représentatif de 3006 adultes habitant l’agglomération parisienne. Les résultats ont confirmé que le modèle des trois repas reste fortement ancré dans les habitudes alimentaires parisiennes. Cependant, l’étude fait ressortir qu’un habitant sur quatre déclare ne faire que deux repas par jour. Elle met en évidence une différence entre hommes et femmes. Les femmes sont plus susceptibles que les hommes de faire trois repas quotidiens, ces derniers étant plus nombreux à prendre deux repas par jour. Pour les femmes, faire deux repas serait le signe d’une vulnérabilité économique et sociale.
A novel adaptive method for minimizing recurrent handoff delays in Mobile IPv6 networks
Creators: name: Siksik, May
Publisher: name: University of British Columbia
Year: 2010

description: Future wireless networks will be entirely based on the IP protocol. High degrees of portability available in an all-IP network will be possible only if we are able to address the insufficiencies of mobility management. One of the major insufficiencies affecting mobility management is the delay associated with the handoff process. During a handoff, the mobile node can become unreachable causing data destined to the node to be lost. As a result, it is important to minimize the delays associated with the handoff process. In this research, we evaluate various mobility management protocols and show that Mobile IPv6 is the most appropriate solution for micro-mobility management. We study the handoff process using Mobile IPv6 and characterize its phases. This characterization shows that move-detection delay is the bottleneck of the handoff process accounting for almost 60% of the combined Layer-2 and Layer-3 handoff delays. To minimize this delay, the router advertisement interval should be set as short as possible without exceeding its assigned bandwidth. This approach has been studied in previous work but only in the context of a single handoff. We propose an improved mobility analysis that assumes a more realistic model that incorporates recurrent handoffs likely to occur during Eager Cell Switching. We then derive an expression for bandwidth that accounts for the non-zero delay separating consecutive handoffs. Further, we use our analysis to provide a new adaptive mobility method capable of dynamically adjusting the advertisement interval as a function of the recurrent cell switching behavior and the available bandwidth. Finally, we verify this model using analysis and simulations using OPNET® and MATLAB® based simulators. Results show the reduction in move detection delay to be as much as 65% using the analysis and as much as 56% using simulation.

description: Dynamical mean-field theory (DMFT) has been employed in conjunction with density functional theory (DFT+DMFT) to investigate the metal-insulator transition (MIT) of strongly correlated $3d$ electrons due to quantum confinement. We shed new light on the microscopic mechanism of the MIT and previously reported anomalous subband mass enhancement, both of which arise as a direct consequence of the quantization of V $xz(yz)$ states in the SrVO$_3$ layers. We therefore show that quantum confinement can sensitively tune the strength of electron correlations, leading the way to applying such approaches in other correlated materials.

description: This paper has two purposes. One is to demonstrate contextuality analysis of systems of epistemic random variables. The other is to evaluate the performance of a new, hierarchical version of the measure of (non)contextuality introduced in earlier publications. As objects of analysis we use impossible figures of the kind created by the Penroses and Escher. We make no assumptions as to how an impossible figure is perceived, taking it instead as a fixed physical object allowing one of several deterministic descriptions. Systems of epistemic random variables are obtained by probabilistically mixing these deterministic systems. This probabilistic mixture reflects our uncertainty or lack of knowledge rather than random variability in the frequentist sense.

description: The $\mathcal{H}_\infty$ control problem is studied for linear constant coefficient descriptor systems. Necessary and sufficient optimality conditions are derived in terms of deflating subspaces of even matrix pencils for index one systems as well as for higher index problems. It is shown that this approach leads to a more robust method in computing the optimal value $\gamma$ in contrast to other methods such as the widely used Riccati based approach. The results are illustrated by a numerical example.
Energy harvesting from ship vibration
Creators: name: Yao, Yao
Publisher: name: University of British Columbia
Year: 2010

description: Advances in low power electronic devices design open up the possibility of self powering a small wireless device from harvested ambient power. In a ship environment, low level vibration is considered as an appropriate power source to extract energy. After a survey of three mechanisms to convert mechanical motion to electricity, electromagnetic conversion was chosen as a mechanism of energy harvesting in this thesis. One of the major drawbacks of today's energy harvesters is that they are designed to provide power of only a few milliwatts and no power conversion control is integrated. Since the power requirement in this thesis is 0.3W, maximum power conversion becomes a critical objective in the harvester design. To achieve this objective, at first, a mathematical model of the electromagnetic converter (linear generator) with a resistive load was developed and the relations of system parameters to power output were deduced. Based on these relations, the design principles of the harvested are summarized into two steps: i) tune the natural frequency of the linear generator to match the main frequency of the vibration spectrum, ii) tune some electrical parameters to maintain the induced voltage at a optimal value which makes the electrical damping factor close to the mechanical damping factor. A power management circuit was designed to condition the power flow to a supercapacitor. The relations deducted with a resistive load still holds in the capacitive load circuitry and thus spring constant and duty cycle of a DC-DC converter become two adjustable variables to control the power. An algorithm " MCCT " makes sure the energy harvester performs maximum power conversion under any conditions based on adjustment of the two variables. Finally, the performance of the energy harvester is assessed under various disturbance scenarios by simulation.

description: We present formulas for the construction of optimal H∞ controllers that can be implemented in a numerically robust way. We base the formulas on the γ-iteration developed in [6]. The controller formulas proposed here avoid the solution of algebraic Riccati equations with their problematic matrix inverses and matrix products. They are also applicable in the neighborhood of the optimal γ, where the classical formulas may call for the inverse of singular or ill-conditioned matrices. The advantages of the new formulas are demonstrated by several numerical examples.

description: We present time-resolved, ultraviolet (UV) spectroscopy of the SW Sex star DW UMa in the high state. We confirm that, shortward of 1500 Å, the high-state, UV continuum level is lower than the white dwarf (WD)-dominated low-state level. We also do not see the WD contact phases in the high state eclipse light curves. These results confirm our earlier finding that the WD in this system is hidden from view in the high state. Based on this, we caution that eclipse mapping of high-inclination SW Sex stars in the high state may yield incorrect or misleading results. In the context of DW UMa, we demonstrate explicitly that distance estimates obtained by recent eclipse mapping studies cannot be reconciled with the WD-dominated low-state spectrum. We also show that the fluxes of the UV emission lines in the high state drop near orbital phase 0.5. This is the first detection of a UV counterpart to the class-defining phase 0.5 absorption seen in the optical emission lines of SW Sex stars.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Graphene antidot lattices (GALs) are two-dimensional (2D) monolayers with periodically placed holes in otherwise pristine graphene. We investigate the electronic properties of symmetric and asymmetric GAL structures having hexagonal holes, and show that anisotropic 2D GALs can display a dimensional crossover such that effectively one-dimensional (1D) electronic structures can be realized in two-dimensions around the charge neutrality point. We investigate the transport and thermoelectric properties of these 2D GALs by using non-equilibrium Green function (NEGF) method. Dimensional crossover manifests itself as transmission plateaus, a characteristic feature of 1D systems, and enhancement of thermoelectric efficiency, where thermoelectric figure of merit, $zT$, can be as high as 0.9 at room temperature. We also study the transport properties in the presence of Anderson disorder and find that mean free paths of effectively 1D electrons of anisotropic configuration are much longer than their isotropic counterparts. We further argue that dimensional crossover due to broken symmetry and enhancement of thermoelectric efficiency can be nanostructuring strategy virtually for all 2D materials.

description: As job redundancy has been recognized as an effective means to improve performance of large-scale computer systems, queueing systems with redundancy have been studied by various authors. Existing results include methods to compute the queue length distribution and response time but only when the service discipline is First-Come-First-Served (FCFS). For other service disciplines, such as Processor Sharing (PS), or Last-Come-First-Served (LCFS), only the stability conditions are known. In this paper we develop the first methods to approximate the queue length distribution in a queueing system with redundancy under various service disciplines. We focus on a system with exponential job sizes, i.i.d. copies, and a large number of servers. We first derive a mean field approximation that is independent of the scheduling policy. In order to study the impact of service discipline, we then derive refinements of this approximation to specific scheduling policies. In the case of Processor Sharing, we provide a pair and a triplet approximation. The pair approximation can be regarded as a refinement of the classic mean field approximation and takes the service discipline into account, while the triplet approximation further refines the pair approximation. We also develop a pair approximation for three other service disciplines: First-Come-First-Served, Limited Processor Sharing and Last-Come-First-Served. We present numerical evidence that shows that all the approximations presented in the paper are highly accurate, but that none of them are asymptotically exact (as the number of servers goes to infinity). This makes these approximations suitable to study the impact of the service discipline on the queue length distribution. Our results show that FCFS yields the shortest queue length, and that the differences are more substantial at higher loads.

description: A tanulmány a V4-es országokban a szarvasmarha-külkereskedelem versenyelőnyeit és hátrányait vizsgálja az EU-27 keretein belül. A vizsgálat az élő és fagyasztott-hűtött szarvasmarha-külkereskedelemre is kiterjed. Azon mutatók alapján, amelyek az export- és importoldalt is vizsgálják (Relatív kereskedelmi előny index – RTA, Relatív versenyképesség – RC), a vizsgált országoknak 2009-ig versenyelőnye volt, majd 2010-től Magyarország, 2011-től pedig Szlovákia kimutatható versenyhátrányba került a vizsgált piacokon. A csak az exportot figyelembe vevő mutatók (Balassa-index, Relatív exportelőny logaritmusa – lnRXA) szerint viszont csak Lengyelországnak volt versenyelőnye az EU-csatlakozás után. A kutatásban meghatározásra került a módosított egységnyi érték mutató (MUVD), ami a 2004-es csatlakozás utáni évben a vizsgált országokban negatív értékeket vett fel, tehát az import átlagára egyre magasabbá vált az exporthoz képest ezekben az országokban. Mind a négy vizsgált országban megállapítható a negatív tendencia az MUVD-mutatót tekintve, különösen a 2008-as válság utáni időszakban. A 2008-ban kezdődő válság mind a négy vizsgált országot érintette, legnagyobb negatív hatása Magyarország esetében volt megfigyelhető. Azonban az MUVD-mutató 2011-es jelentős mértékű javulása reményt keltő lehet a magyar szarvasmarhahús külpiacán.-------------------This paper looks at the competitiveness of the foreign trade of beef and beef cattle of V4 countries within EU27. The analyses cover live cattle and chilled-frozen beef. The indicators which examine export and import together (Relative trade advantage - RTA, Relative competitiveness - RC) show a competitive advantage until 2009 in all examined countries. There is a competitive disadvantage from 2010 in Hungary and from 2011 in Slovakia. The indicator which examines only exports (Balassa-index, Logarithm of the relative export advantage – lnRXA) shows a competitive advantage only in Poland after the EU accession. The fourth applied indicator was the Modified unit value different (MUVD) index which marks negative values after the EU accession in the examined countries. That means the average price of imports was higher than the average price of exports. The negative trend of the MUVD indicator is established in V4 countries especially after the financial crisis in 2008. This concerned all examined countries and the most negative effect was in Hungary which is illustrated by poor values of competitiveness indicators. However the increase in the MUVD indicator in 2011 offers hope for the foreign trade of the Hungarian beef sector.
Clumpy filaments of the Chamaeleon I cloud: C18O mapping with the SEST

description: The Chamaeleon I dark cloud (Cha I} has been mapped in C18O J=1-0 with an angular resolution of 1 arcmin using the SEST telescope. The large scale structures previously observed with lower spatial resolution in the cloud turn into a network of clumpy filaments. The automatic Clumpfind routine developed by Williams et al. 1994 is used to identify individual clumps in a consistent way. Altogether 71 clumps were found and the total mass of these clumps is 230 Mo. The dense 'cores' detected with the NANTEN telescope (Mizuno et al. 1999) and the very cold cores detected in the ISOPHOT serendipity survey (Toth et al. 2000) form parts of these filaments but decompose into numerous 'clumps' The filaments are preferentially oriented at right angles to the large-scale magnetic field in the region. We discuss the cloud structure, the physical characteristics of the clumps and the distribution of young stars. The observed clump mass spectrum is compared with the predictions of the turbulent fragmentation model of Padoan & Nordlund 2002. An agreement is found if fragmentation has been driven by very large-scale hypersonic turbulence, and if it has had time to dissipate into modestly supersonic turbulence in the interclump gas by the present time.

Shortcut to geostrophy in wave-driven rotating turbulence: the quartetic instability

description: We report on laboratory experiments of wave-driven rotating turbulence. A set of wavemakers produces inertial-wave beams that interact nonlinearly in the central region of a water tank mounted on a rotating platform. The forcing thus injects energy into inertial waves only. For moderate forcing amplitude, part of the energy of the forced inertial waves is transferred to subharmonic waves, through a standard triadic resonance instability. This first step is broadly in line with the theory of weak turbulence. Surprisingly however, stronger forcing does not lead to an inertial-wave turbulence regime. Instead, most of the kinetic energy condenses into a vertically invariant geostrophic flow, even though the latter is unforced. We show that resonant quartets of inertial waves can trigger an instability -- the ``quartetic instability'' -- that leads to such spontaneous emergence of geostrophy. In the present experiment, this instability sets in as a secondary instability of the classical triadic instability.

description: We explore the X-ray properties of a subset of the optically selected SDSS cluster sample of Goto et al. (2002), by analysing seven public XMM-{\em Newton} pointings, with exposure times ranging from $\sim$ 4 to 46 ksec. There are in total 17 SDSS clusters out of which only eight are detected at X-ray wavelengths with $\rm f_{0.5-2keV}\magcir 1.2 \times 10^{-14}$ ergs cm$^{-2}$ s$^{-1}$. For the remaining 9 SDSS clusters we estimate their 3$σ$ luminosity upper limits (corresponding to $L_x\mincir 5\times 10^{42}$ ergs/sec in the 0.5-2 keV band). This relatively low luminosity suggests that if real structures, these galaxy aggregations correspond to poor groups of galaxies. Using the SDSS photometric catalogue we also derive the cluster optical $r$-band luminosities. The resulting scaling relations ($L_{\rm opt}-L_x$, $L_{\rm opt}-T_x$) are consistent with those of other recent studies.
