description: Current radiation portal monitors at sea ports and international borders that employ standard radiation detection techniques are not very sensitive to nuclear contraband that is well shielded to absorb emanating radiation. Muon Tomography (MT) based on the measurement of multiple scattering of atmospheric cosmic ray muons traversing cargo or vehicles that contain high-Z material is a promising passive interrogation technique for solving this problem. We report on the design and construction of compact Micro-Pattern Gas Detectors for a small prototype MT station. This station will employ 10 tracking stations based on 30cm x 30cm low-mass triple-GEM detectors with 2D readout. Due to the excellent spatial resolution of GEMs it is sufficient to use a gap of only a few cm between tracking stations. Together with the compact size of the GEM detectors this allows the GEM MT station to be an order of magnitude more compact than MT stations using traditional drift tubes. We present details of the production and assembly of the GEM-based tracking stations in collaboration with CERN and the RD51 collaboration as well as the design of the initial front-end electronics and readout system.

description: Recently an alternative of DDoS attacks called shrew attacks or Reduction of Quality (RoQ) has been identified which is very much difficult to detect. The RoQ attacks can use source and destination IP address spoofing, and they do not have distinct periodicity, and may not filter the attack packets precisely. In this paper, we propose to design the MAC layer based defense architecture for RoQ attacks in Wireless LAN which includes the detection and response stages. The attackers are detected by checking the RTS CTS packets from the MAC layer and the corresponding attack flows are blocked or rejected. By our simulation results, we show that our proposed technique achieves reduces the attack throughput there by increasing the received bandwidth and reducing the packet loss of legitimate users.

subject: 510

description: This workshop continued the biannual series at Oberwolfach on Dynamical Systems that started as the “Moser & Zehnder meeting” in 1981. The main theme of the workshop were the new results and developments in the area of classical dynamical systems, in particular in celestial mechanics and Hamiltonian systems. Among the main topics were new results on Arnold diffusion, new global results on symplectic fixed point theory and the dynamics on Hamiltonian energy surfaces. A high point was Ginzburg’s solution of the Conley conjecture for aspherical symplectic manifolds generalizing recent results by N. Hinston. Another highlight was Mather’s report on Aubry Sets in Small Perturbations of Integrable Systems.
A study of rhabdomyosarcomas induced by nickel sulphide in rats.
Creators: name: Capstick, Valerie
Publisher: name: University of British Columbia
Year: 2011

description: The study of rhabdomyosarcomas induced by nickel sulphide was undertaken in order to investigate their growth and responsiveness characteristics and to evaluate their possible usefulness as experimental tumour systems. A study was also made on the carcinogenic specificity of nickel sulphide. Intramuscular injections of 0.5 to 20 mg. of Ni₃S₂ resulted in tumours after two to six months, which grew fairly rapidly, once palpable. On transplantation they proved to be highly malignant, causing 100 per cent takes within approximately two weeks and death of the host within three to eight weeks. Detailed histological study was performed on many sections of tumour and muscle in order to establish identity of the rhabdomyosarcomas and to observe such cytological phenomena as muscle degeneration, tissue disruption and development of anaplasia. The carcinogenic activity of Ni₃S₂ was emphasized by the rapidity of tumour induction observed after very low doses, while the difference in latent periods suggested some correlation between dose and response. Injections of Ni₃S₂ into body organs illustrated the extreme toxicity of the substance in individual tissues. Although results were somewhat inconclusive within the time limit of the experiment, the general tenor of the data suggested that Ni₃S₂ had a toxic rather than tumourigenic action on most tissues. The appearance of rhabdomyosarcomas when the compound was in contact with abdominal or leg musculature gave evidence that nickel sulphide might have some specificity for striated muscle. Preliminary experiments with NiS indicated that its carcinogenicity, if any, was considerably less than that of Ni₃S₂, with different solubility in muscle being a possible explanation. Several of the induced tumours were used for metabolic and experimental therapy studies with various compounds. Numerous experiments indicated that the tumour was essentially unreliable for such studies since growth rates and response were not reproducible in different tumour generations. However, some general trends were noted. Response to the corticoids ranged from residual to complete inhibition of many tumours during the period of treatment with Cortisol or cortisone. Subcutaneous injections of testosterone showed acceleration of growth in some tumour lines. Tests with the Vinca alkaloids suggested some correlation with clinical anti-tumour effects, indicating an increased effectiveness of both Vinblastine and Vincristine when administered during the first week after transplantation.

Special entangled quantum systems and the Freudenthal construction
Creators: name: Vrana, Péter
name: Lévay, Péter
Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We consider special quantum systems containing both distinguishable and identical constituents. It is shown that for these systems the Freudenthal construction based on cubic Jordan algebras naturally defines entanglement measures invariant under the group of stochastic local operations and classical communication (SLOCC). For this type of multipartite entanglement the SLOCC classes can be explicitly given. These results enable further explicit constructions of multiqubit entanglement measures for distinguishable constituents by embedding them into identical fermionic ones. We also prove that the Plucker relations for the embedding system provide a sufficient and necessary condition for the separability of the embedded one. We argue that this embedding procedure can be regarded as a convenient representation for quantum systems of particles which are really indistinguishable but for some reason they are not in the same state of some inner degree of freedom.

description: The ontology Metadata4Ing is developed within the NFDI Consortium NFDI4Ing with the aim of providing a thorough framework for the semantic description of research data, with a particular focus on engineering sciences and neighbouring disciplines. This ontology allows a thorough description of the whole data generation process (experiment, observation, simulation), embracing the object of investigation, all sample and data manipulation procedures, a summary of the data files and the information contained, and all personal and institutional roles. The subordinate classes and relations can be built according to the two principles of inheritance and modularity. Inheritance means that a subclass inherits all properties of its superordinate class, possibly adding some new ones. Modularity means that all expansions are independent of each other; this makes possible for instance to generate expanded ontologies for any possible combinations of method × object of research.

Bosonization and even Grassmann Variables
Creators: name: M.B. Barbaro
name: A. Molinari
name: F. Palumbo
Publisher: name: INFN Open Access Repository
Year: 1996

description: We test a new approach to bosonization in relativistic field theories and many-body systems, based on the use of fermionic composites as integration variables in the Berezin integral defining the partition function of the system. The method appears promising since at zeroth order it correctly describes the propagators of the composites, which can be evaluated in a number of significant cases. Still to be established is a general procedure for deriving the free action of the composites starting from the one of the constituents. To shed light on this problem and to explore further features of the method we study a simplified version of the BCS model. In this simple case the action of the composites can indeed be obtained: whether this result can be generalized it remains hewever to be seen. Yet an interesting property of the wave operators appearing in the free actions of bilinear composites already emerges from the simple problem we have treated: here the wave operators do not describe any time evolution, even though they generate the right propagators. This outcome relates to the basic properties of the integrals over the even elements of a Grassmann algebra where the composites live, which entails that the propagators are no longer the inverse of the wave operators.
Wavelet and Multiscale Methods

Subjects: subject: Konferenzschrift

description: Various scientific models demand finer and finer resolutions of relevant features. Paradoxically, increasing computational power serves to even heighten this demand. Namely, the wealth of available data itself becomes a major obstruction. Extracting essential information from complex structures and developing rigorous models to quantify the quality of information leads to tasks that are not tractable by standard numerical techniques. The last decade has seen the emergence of several new computational methodologies to address this situation. Their common features are the nonlinearity of the solution methods as well as the ability of separating solution characteristics living on different length scales. Perhaps the most prominent examples lie in multigrid methods and adaptive grid solvers for partial differential equations. These have substantially advanced the frontiers of computability for certain problem classes in numerical analysis. Other highly visible examples are: regression techniques in nonparametric statistical estimation, the design of universal estimators in the context of mathematical learning theory and machine learning; the investigation of greedy algorithms in complexity theory, compression techniques and encoding in signal and image processing; the solution of global operator equations through the compression of fully populated matrices arising from boundary integral equations with the aid of multipole expansions and hierarchical matrices; attacking problems in high spatial dimensions by sparse grid or hyperbolic wavelet concepts. This workshop proposed to deepen the understanding of the underlying mathematical concepts that drive this new evolution of computation and to promote the exchange of ideas emerging in various disciplines.

Subjects: subject: Konferenzschrift
subject: 510

description: The mini-workshop on ”Projective Normality of Smooth Toric Varieties” focused on the question of whether every projective embedding of a smooth toric variety is projectively normal. Equivalently, this question asks whether every lattice point in kP is the sum of k lattice points in P when P is a smooth (lattice) polytope. The workshop consisted of morning talks on different aspects of the problem, and afternoon discussion groups where participants from a variety of different backgrounds worked on specific examples and approaches.
Convex and Algebraic Geometry

Subjects: subject: Konferenzschrift
subject: 510

description: The subjects of convex and algebraic geometry meet primarily in the theory of toric varieties. Toric geometry is the part of algebraic geometry where all maps are given by monomials in suitable coordinates, and all equations are binomial. The combinatorics of the exponents of monomials and binomials is sufficient to embed the geometry of lattice polytopes in algebraic geometry. Recent developments in toric geometry that were discussed during the workshop include applications to mirror symmetry, motivic integration and hypergeometric systems of PDE’s, as well as deformations of (unions of) toric varieties and relations to tropical geometry.
An investigation of the luminosity-metallicity relation for a large sample of low-metallicity emission-line galaxies

description: (abridged) We present 8.2m VLT spectroscopic observations of 28 HII regions in 16 emission-line galaxies and 3.6m ESO telescope spectroscopic observations of 38 HII regions in 28 emission-line galaxies. These emission-line galaxies were selected mainly from the Data Release 6 (DR6) of the Sloan Digital Sky Survey (SDSS) as metal-deficient galaxy candidates. We collect photometric and high-quality spectroscopic data for a large uniform sample of star forming galaxies including new observations. Our aim is to study the luminosity-metallicity (L-Z) relation for nearby galaxies, especially at its low-metallicity end and compare it with that for higher-redshift galaxies. From our new observations we find that the oxygen abundance in 61 out of the 66 HII regions of our sample ranges from 12+logO/H=7.05 to 8.22. Our sample includes 27 new galaxies with 12+logO/H<7.6 which qualify as extremely metal-poor star-forming galaxies (XBCDs). Among them are 10 HII regions with 12+logO/H<7.3. The new sample is combined with a further 93 low-metallicity galaxies with accurate oxygen abundance determinations from our previous studies, yielding in total a high-quality spectroscopic data set of 154 HII regions. 9000 more galaxies with oxygen abundances, based mainly on the Te-method, are compiled from the SDSS. Our data set spans a range of 8 mag with respect to its absolute magnitude in SDSS g (-12>Mg>-20) and nearly 2 dex in its oxygen abundance (7.0<12+logO/H<8.8), allowing us to probe the L-Z relation in the nearby universe down to the lowest currently studied metallicity level. The L-Z relation established on the basis of the present sample is consistent with previous ones obtained for emission-line galaxies.

description: The relativistic corrections to the static potential, i.e. the O(1/m) correction, the O(1/m^2) spin-dependent and momentum-dependent corrections are investigated in SU(3) lattice gauge theory. These corrections are relevant ingredients of an effective field theory for heavy quarkonium called potential nonrelativistic QCD. Utilizing the multilevel algorithm for the field strength correlator on the quark-antiquark source, these corrections are determined at the distances ranged from 0.25 to 1.2 fm. A reasonable scaling behavior and long-range nonperturbative contributions are observed.

description: We report on a cosmic ray test of the FINUDA drift chambers performed inside the FINUDA detector without a magnetic field. From an accurate study of the drift cell space^-time relations we determine both the spatial resolution and the mechanical alignment of the chambers. The chambers operate with a non-saturated 70;% He - 30% iC_4H_10 as mixture and the drift cells are modeled using GARFIELD. After alignment of the drift chamber system, we find a spatial resolution averaged over the entire drift cell and over all angles of incidence of about 140 μm.

The reduction of cupric salts in aqueous solutions by carbon monoxide.
Creators: name: Byerley, John Joseph
Publisher: name: University of British Columbia
Year: 2011

description: The kinetics of the carbon monoxide reduction of Cu(II) to Cu(I) in aqueous solutions were studied at 120°C and carbon monoxide pressures up to 1360 atm. The reduction was followed spectrophoto-metrically in a high pressure titanium cell specifically developed for studying reactions between transition metal ions and gaseous reducing agents. The observed kinetics in acetate-buffered solutions yield a rate law of the form [ Formula omitted ] The rate law describes a reaction that occurs by two parallel paths, one of which is effectively independent of pressure and is accounted for by a stable carbon monoxide complex, described by Cu(CO)+. The pressure-dependent path contains both a pH-dependent and pH-independent reaction. The observed kinetics are consistent with the following mechanism which includes the insertion of a carbon monoxide molecule between a copper ion and a co-ordinated water molecule. [ Formulas omitted ] The effect of complexing was found to be quite minor. This was further verified by studies in sulphate and perchlorate solutions.

description: Equilibrium statistical mechanics studies random fields distributed according to a Gibbs probability measure. Such random fields can be equipped with a stochastic dynamics given by a Markov process with the correspondingly high-dimensional state space. One particular case are stochastic partial differential equations suitably regularized. Another common version is to consider the evolution of random fields taking only values 0 or 1. The workshop was concerned with an understanding of qualitative properties of such high-dimensional Markov processes. Of particular interest are nonreversible dynamics for which the stationary measures are determined only through the dynamics and not given a priori (as would be the case for reversible dynamics). As a general observation, properties on a large scale do not depend on the precise details of the local updating rules. Such kind of universality was a guiding theme of our workshop.

description: The ontology Metadata4Ing is developed within the NFDI Consortium NFDI4Ing with the aim of providing a thorough framework for the semantic description of research data, with a particular focus on engineering sciences and neighbouring disciplines. This ontology allows a thorough description of the whole data generation process (experiment, observation, simulation), embracing the object of investigation, all sample and data manipulation procedures, a summary of the data files and the information contained, and all personal and institutional roles. The subordinate classes and relations can be built according to the two principles of inheritance and modularity. Inheritance means that a subclass inherits all properties of its superordinate class, possibly adding some new ones. Modularity means that all expansions are independent of each other; this makes possible for instance to generate expanded ontologies for any possible combinations of method × object of research. The new version 1.2.0 simplifies the specification of parameters by variables Allows to assign string values to variables Offers the possibility to model value ranges uses qudt terms for unit and quantity kind switches to prov:Agent and prov:Organisation (replacing foaf:Person and foaf:Organisation) updates JSON-LD context file, the documentation, the README and the metadata of the ontology adds a citation.cff file

description: The ability to monitor the progress of students academic performance is a critical issue to the academic community of higher learning. A system for analyzing students results based on cluster analysis and uses standard statistical algorithms to arrange their scores data according to the level of their performance is described. In this paper, we also implemented k mean clustering algorithm for analyzing students result data. The model was combined with the deterministic model to analyze the students results of a private Institution in Nigeria which is a good benchmark to monitor the progression of academic performance of students in higher Institution for the purpose of making an effective decision by the academic planners.

Subjects: subject: Konferenzschrift
subject: 510

description: Many of the various aspects of Noncommutative Geometry were represented in the talks. This includes in particular index theory on foliated spaces, a number of results on spectral triples, noncommutative manifolds and deformation theory, Hopf cyclic theory and K-theoretic and L2 - invariants attached to certain classes of groups. The connections to physics were covered in three talks on quantum field theory on noncommutative spaces such as the Moyal plane, one of the talks giving an attractive survey of the results and techniques in that domain.
Monitoring the wave function by time continuous position measurement

Publisher: name: arXiv
Year: 2009

description: We consider a single copy of a quantum particle moving in a potential and show that it is possible to monitor its complete wave function by only continuously measuring its position. While we assume that the potential is known, no information is available about its state initially. In order to monitor the wave function, an estimate of the wave function is propagated due to the influence of the potential and continuously updated according to the results of the position measurement. We demonstrate by numerical simulations that the estimation reaches arbitrary values of accuracy below 100 percent within a finite time period for the potentials we study. In this way our method grants, a certain time after the beginning of the measurement, an accurate real-time record of the state evolution including the influence of the continuous measurement. Moreover, it is robust against sudden perturbations of the system as for example random momentum kicks from environmental particles, provided they occur not too frequently.

Evolutionary implications of the new triple-alpha nuclear reaction rate for low mass stars

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Context: Ogata et al. (2009; hereafter OKK) presented a theoretical determination of the triple-alpha nuclear reaction rate. Their rate differs from the NACRE rate by many orders of magnitude at temperatures relevant for low mass stars. Aims: We explore the evolutionary implications of adopting the OKK triple-alpha reaction rate in low mass stars and compare the results with those obtained using the NACRE rate. Methods: The triple-alpha reaction rates are compared by following the evolution of stellar models at 1 and 1.5 Msol with Z=0.0002 and Z=0.02. Results: Results show that the OKK rate has severe consequences for the late stages of stellar evolution in low mass stars. Most notable is the shortening--or disappearance--of the red giant phase. Conclusions: The OKK triple-alpha reaction rate is incompatible with observations of extended red giant branches and He burning stars in old stellar systems.

Homotopy Theory
Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2007
Subjects: subject: Konferenzschrift
subject: 510

description: Algebraic topology in general and homotopy theory in particular is in an exciting period of growth and transformation, driven in part by strong interactions with algebraic geometry, mathematical physics, and representation theory, but also driven by new approaches to our classical problems. This workshop was a forum to present and discuss the latest result and ideas in homotopy theory and the connections to other branches of mathematics. Central themes of the workshop were derived algebraic geometry, homotopical invariants for ring spectra such as topological Hochschild homology, interactions with modular representation theory, group actions on spaces and the closely-related study of the classifying spaces of groups.

Subjects: subject: Konferenzschrift
subject: 510

description: Analysis of coagulation and fragmentation is crucial to understanding many processes of scientific and industrial importance. In recent years this has led to intensified research activities in the areas of differential equations, probability theory, and combinatorics. The purpose of the workshop was to bring together people from these different areas working on various aspects of coagulation and fragmentation. We believe that the insights resulting from the interactions which have been stimulated that week should lead to further advances both in the development of mathematical techniques and in new applications.
