description: The introduction of Information and Communication Technology (ICT) in transportation systems leads to several advantages (efficiency of transport, mobility, traffic management). However, it may bring some drawbacks in terms of increasing security challenges, also related to human behaviour. As an example , in the last decades attempts to characterize drivers' behaviour have been mostly targeted. This paper presents Secure Routine, a paradigm that uses driver's habits to driver identification and, in particular, to distinguish the vehicle's owner from other drivers. We evaluate Secure Routine in combination with other three existing research works based on machine learning techniques. Results are measured using well-known metrics and show that Secure Routine outperforms the compared works.

description: Inspired by the discovery of the doubly-charmed and doubly-charged $Ξ_{cc}^{++}$ baryon, in this present work, we investigate spin-1/2 and spin-3/2 mass spectra and magnetic moments of $ccu$ baryon in quark-diquark model with a nonrelativistic potential. In the quark-diquark picture, the three-body problem of the $ccu$ baryon is reduced to the two-body bound state problem. We obtained ground and radially excited mass spectra and magnetic moments of the ground state. Ground state mass spectra agree well with the results in the literature, especially with lattice QCD computations. Predictions for the magnetic moment are compatible with the literature. According to our results, $cu$ diquark clustering in the $Ξ_{cc}^{++}$ baryon is more favorable than the $cc$ diquark clustering.

Water quality modelling in estuaries

Publisher: name: University of British Columbia
Year: 2010

description: A tidally varying and a tidally averaged mass transport model are applied to the Fraser River Estuary to investigate the significance of tidal effects on the concentrations resulting from assumed effluent discharges. The tidally averaged model is due to Thomann [1963]. The tidally varying model is developed from first principles. A hydrodynamic model was used to determine the tidally induced temporal variation in the longitudinal velocity and cross-sectional area along the estuary. All models are "mathematical" and one-dimensional. Finite difference techniques are used to solve the underlying partial differential equations of all three models. The problems of stability and numerical dispersion are examined. Numerical dispersion is seen to result from the solution of the mass transport equation over a fixed space grid rather than along the advective characteristics. Advantages of solving the equation along the characteristics are: no numerical dispersion; the advective and dispersive transport processes are usefully separated; lateral dispersion can be partially assessed with a one-dimensional model; and time dependent behaviour in coefficient of longitudinal dispersion can be taken into account. The tidally varying flows along the estuary are seen to cause a variation in the initial dilution of a discharged effluent. This, together with the effects of tidal flow reversal produces spikes in the concentration profile along the estuary. The concentration of these spikes is then reduced by the dispersion process, the peak concentration during the first two tidal cycles being sensitive to the form and magnitude of the coefficient of longitudinal dispersion. Time dependent variations in this coefficient are considered. The effect of the lateral dispersion process on the estimated concentrations is also considered and secondary flows are tentatively explained in terms of the generation and advection of vorticity. The predicted peak tidally varying concentration was found to be significantly greater than the tidally averaged value.

 Galathea algae Baba, 1977a: 248 (Obi latoe, Ternate, and Seychelles, 0–4 m).— Baba, 1982b: 59 (Palau Islands and Yap Island, subtidal).— Peyrot-Clausade, 1989: 112 (Tuamotu Archipelago, 5–30 m).— Poupin, 1996: 20 (compilation of French Polynesia records).
 Material examined. Holotype: Japan. Off Tosa, Shimizu, Tosa Bay, 27 m, in seabeds, June 1959: 1 M 4.2 mm (ZLKU 7046).
 Paratype: Japan. Off Tosa, Shimizu, Tosa Bay, 27 m, in seabeds, June 1959: 1 F 4.1 mm (ZLKU 7046).
 Remarks. This species was described by Baba (1969), but was later synomized with G. spinosorostris (cf. Baba et al. 2008). However, the examination of the type material from Japan, and a comparison with the topotypic material of G. spinosorostris Dana 1852 from Hawaii (see also Remarks of this latter species) indicates that both species can be distinguished by morphologically and they should be considered as separate species. The two species can be distinguished by the following constant characters:
 - The P1 movable finger has a row of well-developed marginal spines in G. spinosorostris, whereas this finger is unarmed in G. algae.
 - The posteromedian margin of the abdominal somite 6 is convex in G. spinosorostris, instead of transverse in G. algae.
 Galathea algae is also closely related to G. cephyra n. sp. from New Caledonia and G. e u l i m e n e n. sp. from the western Indian Ocean (see below under Remarks of these species).
 No molecular data are available from G. algae.
 Distribution. So far known only from Japan, Tosa Bay, 27 m.

description: On 2008 May 14, the Burst Alert Telescope aboard the Swift mission triggered on a type-I X-ray burst from the previously unclassified ROSAT object 1RXH J173523.7-354013, establishing the source as a neutron star X-ray binary. We report on X-ray, optical and near-infrared observations of this system. The X-ray burst had a duration of ~2 h and belongs to the class of rare, intermediately long type-I X-ray bursts. From the bolometric peak flux of ~3.5E-8 erg/cm^2/s, we infer a source distance of D<9.5 kpc. Photometry of the field reveals an optical counterpart that declined from R=15.9 during the X-ray burst to R=18.9 thereafter. Analysis of post-burst Swift/XRT observations, as well as archival XMM-Newton and ROSAT data suggests that the system is persistent at a 0.5-10 keV luminosity of ~2E35 (D/9.5 kpc)^2 erg/s. Optical and infrared photometry together with the detection of a narrow Halpha emission line (FWHM=292+/-9 km/s, EW=-9.0+/-0.4 Angstrom) in the optical spectrum confirms that 1RXH J173523.7-354013 is a neutron star low-mass X-ray binary. The Halpha emission demonstrates that the donor star is hydrogen-rich, which effectively rules out that this system is an ultra-compact X-ray binary.

description: Resumo A ideia dos valores, a sua origem, natureza e formas de manifestação na sociedade, como via de contribuição para o entendimento da discussão do resgate de valores em face das novas tendências que se afirmam constitui-se num problema sempre actual e actuante na história do homem. A instituição dos valores morais socialmente aceites, a sua degradação em face do surgimento de novos comportamentos que gradualmente se afirmam como valores socialmente aceites e com força moral, constituiu uma problemática tanto para as gerações passadas, as actuais e as surgentes, entretanto irreversíveis. Não poucas vezes nos deparamos com esforços, em forma de programas ou projectos, para a manutenção e resgate de valores morais vigentes, no mundo em geral e na sociedade angolana em particular, o que constitui um falso problema, quando entendido a partir da natureza metamórfica dos valores. Sucede que com o decorrer dos tempos, as novas gerações manifestam comportamentos que muitas vezes chocam com os valores socialmente estabelecidos, o que leva educadores a manifestarem-se indignados com tais comportamentos, manifestando-se grandemente a favor do resgate de valores que se degradam. A questão que procuramos responder neste artigo é, se é possível resgatar valores socialmente desgastados por ineficiência promovida pela industrialização e pelas tecnologias, e se é possível, quais os valores que podem ou não ser resgatados. Palavras-chave: Resgate de valores, moral, social.

description: We investigate the behavior of the deflection of light rays by charged and rotating AdS black holes using the Gauss-Bonnet formalism. Taking weak field approximations and certain appropriate limits associated with AdS geometries, we compute and analyze such an optical quantity by varying the involved moduli space parameters. First, we study the charge and the AdS radius effects on the deflection angle of RN-AdS black holes. For small values of the impact parameter $b$, we find that the charge effect is relevant. Precisely, it decreases the deflection angle, while the AdS background one is not. For large values of $b$, however, these optical behaviors have been inverted and the deflection angle becomes an increasing function of the charge. In this way, the cosmological constant effect is remarked to be relevant showing linear variations of the deflection angle. Varying the charge, we find a critical impact parameter value $b_{c}$ where the charge effect is inverted. For rotating solutions, we show that the spinning parameter still decreases the deflection angle without any changing behavior observed in the charge effect. Evincing of the cosmological constant, we recover known results corresponding to charged and rotating ordinary black hole solutions. Examining the plasma effect, we reveal that the deflection angle keeps the same behavior being a decreasing function in terms of the frequency ratio.

description: We designed and synthesised a reactive mesogen containing diphenylacetylene moiety in the mesogenic core and two polymerisable acrylate groups at both ends. By irradiating linearly polarised UV light on the conventional host LC mixture containing a small amount of the synthesised reactive mesogen in a sandwiched cell without an alignment layer, we demonstrated an in-situ photo-induced homogeneous alignment of liquid crystals without a pre-treated alignment layer, which was achieved by an irreversible polarisation-selective [2 + 2] photodimerization of diphenylacetylene moiety with linearly polarised UV irradiation at above the isotropic temperature of LC mixture. The resulting homogeneous alignment showed a superior initial dark state, negligible pretilt angle and excellent stabilities. Furthermore, the in-plane switching (IPS) LC cell prepared by this method exhibited a better dark state and electro-optic performance compared to that with conventional-rubbed polyimide alignment layer. The single photoirradiation process automatically resulted in a perfect alignment matching of optical axes between the top and bottom substrates in the LC cell, giving rise to an excellent dark state overcoming an intrinsic misalignment issue and complex fabrication process. The proposed in-situ alignment method is a promising candidate for cost-effective, green-manufacturing, and high-quality alignment technique in the manufacturing of high-resolution liquid crystal displays.

description: In this paper, we address the problem of distributing a large amount of bulk data to a sparse vehicular network from roadside infostations, using efficient vehicle-to-vehicle collaboration. Due to the highly dynamic nature of the underlying vehicular network topology, we depart from architectures requiring centralized coordination, reliable MAC scheduling, or global network state knowledge, and instead adopt a distributed paradigm with simple protocols. In other words, we investigate the problem of reliable dissemination from multiple sources when each node in the network shares a limited amount of its resources for cooperating with others. By using \emph{rateless} coding at the Road Side Unit (RSU) and using vehicles as data carriers, we describe an efficient way to achieve reliable dissemination to all nodes (even disconnected clusters in the network). In the nutshell, we explore vehicles as mobile storage devices. We then develop a method to keep the density of the rateless codes packets as a function of distance from the RSU at the desired level set for the target decoding distance. We investigate various tradeoffs involving buffer size, maximum capacity, and the mobility parameter of the vehicles.

description: To enlarge the perception range and reliability of individual autonomous vehicles, cooperative perception has been received much attention. However, considering the high volume of shared messages, limited bandwidth and computation resources in vehicular networks become bottlenecks. In this paper, we investigate how to balance the volume of shared messages and constrained resources in fog-based vehicular networks. To this end, we first characterize sum satisfaction of cooperative perception taking account of its spatial-temporal value and latency performance. Next, the sensing block message, communication resource block, and computation resource are jointly allocated to maximize the sum satisfaction of cooperative perception, while satisfying the maximum latency and sojourn time constraints of vehicles. Owing to its non-convexity, we decouple the original problem into two separate sub-problems and devise corresponding solutions. Simulation results demonstrate that our proposed scheme can effectively boost the sum satisfaction of cooperative perception compared with existing baselines.

Scaling approach to existence of long cycles in Casimir boxes

description: We analyse the concept of generalized Bose-Einstein condensation (g-BEC), known since 1982 for the perfect Bose gas (PBG) in the Casimir (or anisotropic) boxes. Our aim is to establish a relation between this phenomenon and two concepts: the concept of long cycles and the Off-Diagonal-Long-Range-Order (ODLRO), which are usually considered as some adequate way to describe the standard BEC on the ground state for the cubic boxes. First we show that these three criterions are equivalent in this latter case. Then, basing on a scaling approach, we revise formu- lation of these concepts to prove that the classification of the g-BEC into three types I,II,III, implies a hierarchy of long cycles (depending on their size scale) as well as a hierarchy of ODLRO which depends on the coherence length of the condensate.

description: The generalized Pareto distribution was introduced by Pickands (1975). Three methods of estimating the parameters of the generalized Pareto distribution were compared by Hosking and Wallis (1987) . The methods are maximum likelihood, method of moments and probability-weighted moments.
An alternate method of estimation for the generalized Pareto distribution, based on least square regression of expected order statistics (REOS), is developed and evaluated in this thesis . A Monte Carlo comparison is made between this method and the estimating methods considered by Hosking and Wallis (1987). This method is shown to be generally superior to the maximum likelihood, method of moments and probability-weighted moments.

description: In this paper we study polynomial maps of vector spaces and their eigenvectors and eigenvalues. The new quantity called complanart is defined. Complanarts determine complanarity of solution vectors of systems of polynomial equations. Evaluation of complanart is reduced to evaluation of resultants. As in linear case, the pattern of eigenvectors defines the phase diagram of associated differential equation. Theory of such differential equations arise naturally as extension of Lyapunov's theory of stability for solutions of differential equations. The results of this work have a number of potential applications: from solving non-linear differential equations and calculating non-linear exponents to taking non-Gaussian integrals.

title: Overall Life Satisfaction of Ileostomates: Conventional Brooke Ileostomy Versus Modified Kock Pouch
Creators: name: Briscoe, Sandra Sisson
Publisher: name: Utah State University
Year: 1988

description: The purpose of this thesis is to analyze various aspects of quality of life and to determine if there is a difference in quality of life offered by a conventional ileostomy versus a continent ileostomy.
An instrument was developed to measure several factors thought to influence quality of life as well as several structural/demographic variables. This instrument was designed for persons with a conventional ileostomy and was modified for persons who had undergone conversion surgery from conventional to continent ileostomy.
Analysis of variance was performed to determine differences in quality of life for persons with a conventional, conversion, or original continent ileostomy. In addition to an overall quality of life measure, measures for specific areas: self esteem, family relationships, marriage relationships and a composite measure, were tested. No difference was detected for the three types of ileostomy for these variables.
Analysis of variance was also performed on variables measuring specific aspects of life such as social activities and travel. This identified several differences in the ileostomy types which the analysis of the more general variables failed to detect. Those who had conversion surgery from conventional to continent ileostomies answered each question twice, comparing life with no ileostomy to life with a conventional, then comparing life with a conventional ileostomy to life with a continent. Three analyses were performed on the resulting data: sign test, chi-square test, and Fisher's exact test. The use of these three tests showed differences in results concerning quality of life and differences in the statistical power of the tests. Both aspects are discussed. Significant improvement in quality of life for almost every aspect tested was seen for this group.
Finally, principal component analysis was applied to the set of variables measuring specific aspects of quality of life and several new variables developed from the resulting factors. Analysis of variance was performed on these, as well as the original quality of life measures to determine which of the structural/demographic variables had an effect on quality of life.

description: We present an 880 micron Submillimeter Array (SMA) detection of the submillimeter galaxy SXDF850.6. SXDF850.6 is a bright source (S(850 micron) = 8 mJy) detected in the SCUBA Half Degree Extragalactic Survey (SHADES), and has multiple possible radio counterparts in its deep radio image obtained at the VLA. Our new SMA detection finds that the submm emission coincides with the brightest radio emission that is found ~8" north of the coordinates determined from SCUBA. Despite the lack of detectable counterparts in deep UV/optical images, we find a source at the SMA position in near-infrared and longer wavelength images. We perform SED model fits to UV-optical-IR photometry (u, B, V, R, i', z', J, H, K, 3.6 micron, 4.5 micron, 5.8 micron, and 8.0 micron) and to submm-radio photometry (850 micron, 880 micron, 1100 micron, and 21 cm) independently, and we find both are well described by starburst templates at a redshift of z ~= 2.2 (+/- 0.3). The best-fit parameters from the UV-optical-IR SED fit are a redshift of z = 1.87 (+0.15/-0.07), a stellar mass of M_star = 2.5 +2.2/-0.3 x 10^11 M_sun, an extinction of A_V = 3.0 (+0.3/-1.0) mag, and an age of 720 (+1880/-210) Myr. The submm-radio SED fit provides a consistent redshift of z ~ 1.8-2.5, an IR luminosity of L_IR = (7-26) x 10^12 L_sun, and a star formation rate of 1300-4500 M_sun/yr. These results suggest that SXDF850.6 is a mature system already having a massive amount of old stellar population constructed before its submm bright phase and is experiencing a dusty starburst, possibly induced by major mergers.

description: Confidence intervals are a standard technique for analyzing data. When applied to time series, confidence intervals are computed for each time point separately. Alternatively, we can compute confidence bands, where we are required to find the smallest area enveloping $k$ time series, where $k$ is a user parameter. Confidence bands can be then used to detect abnormal time series, not just individual observations within the time series. We will show that despite being an NP-hard problem it is possible to find optimal confidence band for some $k$. We do this by considering a different problem: discovering regularized bands, where we minimize the envelope area minus the number of included time series weighted by a parameter $α$. Unlike normal confidence bands we can solve the problem exactly by using a minimum cut. By varying $α$ we can obtain solutions for various $k$. If we have a constraint $k$ for which we cannot find appropriate $α$, we demonstrate a simple algorithm that yields $O(\sqrt{n})$ approximation guarantee by connecting the problem to a minimum $k$-union problem. This connection also implies that we cannot approximate the problem better than $O(n^{1/4})$ under some (mild) assumptions. Finally, we consider a variant where instead of minimizing the area we minimize the maximum width. Here, we demonstrate a simple 2-approximation algorithm and show that we cannot achieve better approximation guarantee.

description: 3C 454.3 is a flat spectrum radio quasar (FSRQ) known for its high variability across the electromagnetic spectrum, showing structural and flux variability in its pc-scale jet, and correlated variability among frequency bands. This study aims to identify the structure, dynamics, and radiative processes common to the innermost regions of the blazar 3C 454.3. We investigate whether any jet component can be associated with $γ-$ray emission and variability. We analyze the relationship between the variable $γ-$ray emission and pc-scale jet properties in 3C 454.3 by combining $γ-$ray data spanning twelve years with contemporaneous VLBA multi-epoch images at 15 and 43 GHz. Spearman rank correlation tests are conducted to determine if the flux variability of any jet component is associated with $γ-$ray variability. Core emission at 43 and 15 GHz strongly correlates with $γ-$ray emission. The 43 GHz core (Q0) contributes around 37$\%$ of the observed $γ-$ray variability, while the 15 GHz core (K0) accounts for 30$\%$. A quasi-stationary component at 43 GHz, at a projected distance of 4.6 pc, correlates with the $γ-$ray flux, accounting for 20$\%$ of its emission between 2016 and 2021. We found a mobile component (Q3 between 2010.18 and 2011.16) at 43 GHz with a projected distance between 0.8 and 2.3 pc and apparent velocity of $β_{app} = 9.9 \pm 1.1$ c, accounting for approximately 28% of the $γ-$ray emission. The observed simultaneous variability in emission regions beyond the central parsec strongly suggests synchrotron self-Compton (SSC) as the primary mechanism for $γ-$ray production in these regions. Our findings demonstrate the existence of multiple $γ-$ray emission regions within the blazar jet but also suggest that some of these regions are non-stationary over time.

All of the computer programs described in this paper have been written for use on microcomputers and so the feasibility of using microcomputers is also discussed. Finally, numbers of various forms have been considered for primality with special attention given to Mersenne and Fermat numbers. It is hoped that some of the information contained in this paper may provide worthwhile enrichment ideas for mathematics educators.

title: Numerical Methods (Finite Element) for Time-Dependent Partial Differential Equations
Creators: name: Watanabe, Masaji
Publisher: name: Utah State University
Year: 1982

description: This paper surveys reasons why the Ritz method and the Galerkin method are not efficient and why these methods can not be applied directly, for time dependent problems. It also introduces methods that are used for those problems. For a linear boundary value problem defined by a positive definite symmetric (self-adjoint) operator, the existence and the convergence of the Ritz approximation are guaranteed. In non-symmetric case, Lax-Milgram lemma assures the existence and the convergence of the Galerkin approximation for H1/2(Ω)-elliptic operator. Since time dependent problems are hyperbolic or parabolic, the existence and the convergence of approximations by those methods are not guaranteed. Moreover, those methods were originally developed for boundary value problems. Thus new techniques are introduced in order to extend those methods to initial-boundary value problems.

description: We describe an algorithm for comparing two RNA secondary structures coded in the form of trees that introduces two new operations, called node fusion and edge fusion, besides the tree edit operations of deletion, insertion, and relabeling classically used in the literature. This allows us to address some serious limitations of the more traditional tree edit operations when the trees represent RNAs and what is searched for is a common structural core of two RNAs. Although the algorithm complexity has an exponential term, this term depends only on the number of successive fusions that may be applied to a same node, not on the total number of fusions. The algorithm remains therefore efficient in practice and is used for illustrative purposes on ribosomal as well as on other types of RNAs.
Removal of heavy metals using granular coal
Creators: name: Riaz, Muhammad
Publisher: name: University of British Columbia

description: In view of very high toxicity potential of some heavy metals to aquatic life, there is a need for critical evaluation of known methods and development of new methods for purifying water and waste-water containing heavy metals. In this study, batch tests were performed to evaluate the relative efficiencies of six British Columbia coals in removing heavy metals (copper, lead, mercury and zinc) from water. On the basis of batch test data obtained, the best two coals, Kaiser Coal-Stock Pile Refuse and Kaiser Coal-Special Plant Feed, were tested on a continuous flow laboratory scale. The emphasis was placed on metal concentrations of 2 mg/1 and less for copper, lead and zinc and 5 vg/1 for mercury. The effects of adsorbate concentration, flow rate through the column (contact time), and pH of the solution on the adsorptive capacity of coal were investigated. A solution containing 0.5 mg/1 of each of copper, lead and zinc was tested to investigate the ability of the coal to remove metals from a mixture of many metals. The adsorptive capacity of the best two coals was also compared with some commercially available adsorbents. On the basis of capacity and rate of adsorption, Kaiser Coal-Stock Pile Refuse was found to be the best of the six coals tested. For the specific testing conditions in this investigation, the better metal-removing efficiency of coal as compared with activated carbon and nitrohumic acid indicate that the coal may be a feasible alternate to purify effluents containing heavy metals

THE ROLE OF THE HYPOXIA INDUCIBLE FACTOR (HIF-1?) IN MYOGENESIS
Creators: name: RESMINI, GIULIA

description: Regeneration of skeletal muscle is a complex process that requires the activation of quiescent adult stem cells, the satellite cells, which are resident in hypoxic niches in the tissue. This process is mainly regulated through a group of transcription factors known as the hypoxia-inducible factors (HIFs). In particular, HIF-1? activation has been described as beneficial for the cell to overcome an hypoxic insult, while it has been observed that its chronic activation completely inhibits skeletal muscle differentiation. Therefore, oxygen deprivation and HIF-1? may play a role in activating the initial steps of the regeneration process. Herein, we investigated whether a 24h pre-conditioning under physical (1% O2) or chemical (IOX2 and FG-4592, two commercial PHDs inhibitors) hypoxic culture conditions could alter the differentiation of C2C12 myoblasts. In this thesis work we report that a controlled stimulus can trigger HIF-1?, activating MyoD through the non-canonical Wnt/?-catenin pathway and resulting in muscle hypertrophy. In particular, results show that both an hypoxic and a chemical pre-conditioning promotes the increase of all differentiation markers and the up-regulation of the non-canonical WNT pathway involved in myogenesis. Moreover, HIF-1? silencing significantly reduced cell differentiation, down-regulating MyoD and MHC as well as the expression of WNT7a. Finally, we studied the mechanism of WNT7a activation mediated by HIF-1?. Our results showed that HIF-1? activation induced an enhancement of WNT7a promoter activity, therefore we focused on the identification of the HIF-1? binding sequences localized on WNT7a promoter. Two different regions of over-lapping were identified by ChIP experiments, validating that HIF-1? directly binds WNT7a promoter and regulates its gene expression. In conclusion, we demonstrated the crucial role played by HIF-1? during skeletal muscle differentiation, and our results revealed that PHDs inhibitors could be used to mimic the effects obtained under hypoxic conditions. In addition, we define HIF-1? as a new possible candidate to induce the activation of WNT7a, which characterized the hypertrophic phenotype of the skeletal muscle. Altogether these results support the notion that HIF-1? plays a pivotal role in activating the regeneration process and may suggest new perspective for novel therapeutic targets in the treatment of several muscle diseases.

description: Self-organizing maps (SOMs) are a technique that has been used with high-dimensional data vectors to develop an archetypal set of states (nodes) that span, in some sense, the high-dimensional space. Noteworthy applications include weather states as described by weather variables over a region and speech patterns as characterized by frequencies in time. The SOM approach is essentially a neural network model that implements a nonlinear projection from a high-dimensional input space to a low-dimensional array of neurons. In the process, it also becomes a clustering technique, assigning to any vector in the high-dimensional data space the node (neuron) to which it is closest (using, say, Euclidean distance) in the data space. The number of nodes is thus equal to the number of clusters. However, the primary use for the SOM is as a representation technique, that is, finding a set of nodes which representatively span the high-dimensional space. These nodes are typically displayed using maps to enable visualization of the continuum of the data space. The technique does not appear to have been discussed in the statistics literature so it is our intent here to bring it to the attention of the community. The technique is implemented algorithmically through a training set of vectors. However, through the introduction of stochasticity in the form of a space--time process model, we seek to illuminate and interpret its performance in the context of application to daily data collection. That is, the observed daily state vectors are viewed as a time series of multivariate process realizations which we try to understand under the dimension reduction achieved by the SOM procedure.

description: We present the findings of the first years of activity of the Lombardy registry of sinonasal cancers (SNC), which was started at the end of 2007. The registry collects all potential cases of primary malignant epithelial neoplasm of the nasal cavity and accessory sinuses, verifies clinical records, and interviews the patients or their next-of-kin to investigate exposures to known SNC carcinogens. Case ascertainment is complete for the year 2008: we recorded 31 verified cases among men and 24 among women. The age-standardized regional incidence rates were 0.8 and 0.5 ? 100,000 in men and women, respectively. For 87 cases diagnosed in 2008-2010 period we obtained an interview. In 34 cases (32 M and 2 F), we documented occupational exposure to wood dust (61.8%), leather dust (29.4%), bitumen fumes (5.9%), and hexavalent chromium compounds (2.9%). For these subjects compensation claims were undertaken. In 4 cases we found leisure-time exposures. In 49 cases (56.3%) no evidence of exposure to known SNC carcinogens was found.

 Galathea anepipoda Baba, 1990: 953, fig. 12 (Madagascar, 85–150 m).—Baba et al. 2008: 65 (in part, compilation).
 Galathea balssi.— Tirmizi & Javed, 1993: 47, fig. 21 (off Somali Republic, Mozambique Channel, and central part of Indian Ocean, 47–165 m) (not Galathea balssi Miyake & Baba, 1967).
Dubious identifications:
 Galathea orientalis.— Tirmizi, 1966: 182, figs 6–8 (Red Sea, South Arabian Sea, 29–100 m).
 Galathea anepipoda.— Baba, 2005: 74, 243 (Sagami Bay, Japan, 366–732 m, Kei Islands, 245 m).— Dong & Li, 2010: 2, fig. 1 (East China Sea, 106–110 m) (possibly G. paleroi n.sp.).
 Material examined. Mozambique. MAINBAZA, Stn CP3132, 25°11.24`S, 35°01.51’E, 101–102 m, 10 Abril 2009: 1 ov. F 3.3 mm (MNHN-IU-2013-8306).
Madagascar. ATIMO VATAE, Stn CP3512, 25°15'S, 47°17'E, 140–144 m, 29 April 2010: 1 ov. F 3.4 mm (MNHN-IU-2010-4022).—Stn CP3620, 25°47'S, 46°02'E, 133–178 m, 15 May 2010: 1 ov. F 3.2 mm (MNHN-IU- 2013-8307).
 Remarks. The specimens illustrated by Tirmizi & Javed (1993), and identified as G. balssi, probably belong to G. anepipoda. Further analyses should confirm the identity of these specimens, as well as other material collected by Tirmizi (1966), Baba (2005) and Dong & Li (2010). The descriptions and illustrations provided by these authors suggest that they do not belong to G. anepipoda. The genetic divergence between G. anepipoda and G. balssi is quite large (13.1% COI) (Tab. 1).
 Distribution. Western Indian Ocean from the Red Sea to Madagascar and Mozambique, 47– 165 m. The records from Japan and East China Sea should be revised.
