description: This paper is devoted to the leading twist exclusive bottomonia decays with double charmonium in the final state. Using models of the twist-2 charmonia distribution amplitudes the widths of these decays are calculated within light cone formalism. In addition, the processes under consideration are studied within nonrelativistic QCD. In our analysis we have found that the production of some of the $P$-wave charmonia mesons with $L_z \neq 0$ is allowed already at the leading twist approximation. This means that the selection rules which predict the suppression of such decays are violated. The mechanism which lies behind this violation is discussed.

description: Photonuclear reactions at energies covering the giant dipole resonance (GDR) region are analyzed with an approach based on nuclear photoabsorption followed by the process of competition between light particle evaporation and fission for the excited nucleus. The photoabsorption cross section at energies covering the GDR region is contributed by both the Lorentz type GDR cross section and the quasideuteron cross section. The evaporation-fission process of the compound nucleus is simulated in a Monte-Carlo framework. Photofission reaction cross sections are analyzed in a systematic manner in the energy range of $\sim$ 10-20 MeV for the actinides $^{232}$Th, $^{238}$U and $^{237}$Np. Photonuclear cross sections for the medium-mass nuclei $^{63}$Cu and $^{64}$Zn, for which there are no fission events, are also presented. The study reproduces satisfactorily the available experimental data of photofission cross sections at GDR energy region and the increasing trend of nuclear fissility with the fissility parameter $Z^2/A$ for the actinides.

description: Die "Do-it-all“-Mutter - Diskursive Strategien und post-feministische Allianzen in Elternzeitschriften. Der Artikel analysiert diskursive Strategien in aktuellen deutschen Elternzeitschriften. Es wird beobachtet, dass "Mutterschaft" zugleich mit konservativen Geschlechterrollen verbunden ist und in einen individualistischen postfeministischen Diskurs eingebettet ist. Es wird gezeigt, wie die analysierten Texte konservative Modelle von Mutterschaft und Geschlecht, insbesondere in Bezug auf die Mutter-Kind-Beziehung, die Frage der "Kompatibilität" von unbezahlter und bezahlter Arbeit und geschlechtsspezifischen Elternstellungen, in eine modern scheinende Rhetorik einkleiden. Durch die diskursiven Strategien und Allianzen werden die politischen und strukturellen Dimensionen von Care-Arbeit, Geschlechtergerechtigkeit und intersektionalen Aspekten durch den individualistischen Diskurs verdeckt. Diese Entpolitisierung wird ans Licht gebracht und damit Raum für neue feministische Perspektiven der Mutterschaft geschaffen.

Anhand von Forschungen zu bolivianischen Migrantinnen und im Sextourismus tätigen brasilianischen Frauen zeichnet der Beitrag die Bedeutung lokaler Kontexte und der Nord-Süd-Verhältnisse für die Migration und das Leben in Europa nach. Ausgehend von den Erfahrungen der Interviewten und im Anschluss an körperpraxeologische Ansätze wird untersucht, wie die Frauen Körperpraktiken und sexualisierte sowie exotisierende Repräsentationen gezielt für räumliche und soziale Mobilität einsetzen. Mit Bezug auf queertheoretische und dekoloniale Perspektiven werden nicht nur die durch Mobilitätsstrategien erzielten Handlungsspielräume der Interviewten, sondern auch die normative Bedeutung rassifizierter und klassistischer Sexualitätskonzepte für die Konstitution von Grenzregimen und ihrer gewaltvollen Effekte aufgezeigt.

In diesem Beitrag stellen wir ‚Western Code‘ trans*-Narrative in Frage, indem wir das koloniale Projekt der Medikalisierung, Pathologisierung und Disziplinierung von trans* Körpern beleuchten. Wir untersuchen zunächst verschiedene Kontrollsysteme – Biologisierung, Zeitlichkeit, Klassifizierung und Pathologisierung – die in Bezug auf (trans*)gender in ‘Western codes’ wirken. Danach befassen wir uns mit Aspekten trans*spezifischer Gesundheitsversorgung und ihres kolonialen Erbes. In beiden Abschnitten konzentrieren wir uns dabei auf „Unsichtbarkeitsfelder“ (in Deutschland und Südafrika) – die verborgenen Machtstrukturen, die das koloniale Projekt als das Problem anderer Leute verschleiern. In dem Versuch „Western Code“ trans* Narrative zu provinzialisieren und zu unter_brechen eröffnen wir am Ende alternative Erzählungen und Geschichten des Widerstands.

description: We show that the mu problem and the strong CP problem can be resolved in the context of the gauged U(1)_R symmetry, realizing an automatic Peccei-Quinn symmetry. In this scheme, right-handed neutrinos can be introduced to explain small Majorana or Dirac neutrino mass. The U(1)_R D-term mediated SUSY breaking, called the U(1)_R mediation, gives rise to a specific form of the flavor-conserving superpartner masses. For the given solution to the mu problem, electroweak symmetry breaking condition requires the superpartners of the Standard Model at low energy to be much heavier than the gravitino. Thus dark matter candidate can be either gravitino or right-handed sneutrino. In the Majorana neutrino case, only gravitino is a natural dark matter candidate. On the other hand, in the Dirac neutrino case, the right-handed sneutrino can be also a dark matter candidate as it gets mass only from SUSY breaking. We discuss the non-thermal production of our dark matter candidates from the late decay of stau and find that the constraints from the Big Bang Nucleosynthesis can be evaded for a TeV-scale stau mass.

A Short Review on Jet Identification

Year: 2008
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: Jets can be used to probe the physical properties of the high energy density matter created in collisions at the Relativistic Heavy Ion Collider (RHIC). Measurements of strong suppression of inclusive hadron distributions and di-hadron correlations at high $p_{T}$ have already provided evidence for partonic energy loss. However, these measurements suffer from well-known geometric biases due to the competition of energy loss and fragmentation. These biases can be avoided if the jets are reconstructed independently of their fragmentation details - quenched or unquenched. In this paper, we discuss modern jet reconstruction algorithms (cone and sequential recombination) and their corresponding background subtraction techniques required by the high multiplicities of heavy ion collisions. We review recent results from the STAR experiment at RHIC on direct jet reconstruction in central Au+Au collisions at $\sqrt {s_{NN}}= 200$ GeV.

Is an Ultra-Cold Strongly Interacting Fermi Gas a Perfect Fluid?
Creators: name: Thomas, J. E.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Gases (cond-mat.quant-gas)
subject: FOS: Physical sciences

description: Fermi gases with magnetically tunable interactions provide a clean and controllable laboratory system for modeling interparticle interactions between fermions in nature. The s-wave scattering length, which is dominant a low temperature, is made to diverge by tuning near a collisional (Feshbach) resonance. In this regime, two-component Fermi gases are stable and strongly interacting, enabling tests of nonperturbative many-body theories in a variety of disciplines, from high temperature superconductors to neutron matter and quark-gluon plasmas. We have developed model-independent methods for measuring the entropy and energy of this model system, providing a benchmark for calculations of the thermodynamics. Our experiments on the expansion of rotating strongly interacting Fermi gases in the normal fluid regime reveal extremely low viscosity hydrodynamics. Combining the thermodynamic and hydrodynamic measurements enables an estimate of the ratio of the shear viscosity to the entropy density. A strongly interacting Fermi gas in the normal fluid regime is found to be a nearly perfect fluid, where the ratio of the viscosity to the entropy density is close to a universal minimum that has been conjectured by string theory methods.

description: It is known that Berry curvature of the band structure of certain crystals can lead to effective noncommutativity between spatial coordinates. Using the techniques of twisted quantum field theory, we investigate the question of the formation of a paired state of twisted fermions in such a system. We find that to leading order in the noncommutativity parameter, the gap between the non-interacting ground state and the paired state is {\it smaller} compared to its commutative counterpart. This suggests that BCS type superconductivity, if present in such systems, is more fragile and easier to disrupt.

description: Let $P$ be a polytope with rational vertices. A classical theorem of Ehrhart states that the number of lattice points in the dilations $P(n) = nP$ is a quasi-polynomial in $n$. We generalize this theorem by allowing the vertices of P(n) to be arbitrary rational functions in $n$. In this case we prove that the number of lattice points in P(n) is a quasi-polynomial for $n$ sufficiently large. Our work was motivated by a conjecture of Ehrhart on the number of solutions to parametrized linear Diophantine equations whose coefficients are polynomials in $n$, and we explain how these two problems are related.

Efficient Data Flow Constraint Analysis

Publisher: name: Karlsruhe
Year: 2018

description: Aktuelle Entwicklungen in der Software-Technik zeigen einen Trend zur Dezentralisierung von Software-Systemen. Mit dem Einsatz von Techniken wie Cloud-Computing oder Micro-Services fließen immer mehr Daten über öffentliche Netzwerke oder über die Infrastruktur von Drittanbietern. Im Gegensatz dazu führen aktuelle gesetzliche Änderungen wie die Datenschutz-Grundverordnung dazu, dass es für Software-Entwickler immer wichtiger wird sicherzustellen, dass die Datenflüsse ihrer Software gesetzliche Beschränkungen einhalten. Um dies trotz der stetig wachsenden Komplexität von Software-Systemen zu ermöglichen wurden verschiedene modellbasierte Ansätze auf Architekturebene vorgeschlagen. Ein Nachteil der meisten Ansätze ist jedoch, dass sie oftmals keine voll automatisierte Analyse bezüglich der Verletzung von Datenflussbeschränkungen ermöglichen. Oft sind keine automatisierten Analysen möglich oder Analysen müssen individuell für jedes Szenario entwickelt werden. Aus diesem Grund schlagen wir ein neues Metamodell zur Beschreibung der Datenflüssen von Softwaresystemen vor. Dieses Metamodell ist so entworfen, dass eine automatisierte Übersetzung von Instanzen in ein Programm der logischen Programmiersprache Prolog ermöglicht wird. Dieses Programm erlaubt dann die einfache Formulierung von Regeln zur automatisierten Prüfung der Einhaltung von Datenflussbeschränkungen. Ein wichtiger Aspekt für den Entwurf und die Implementierung unseres Ansatzes ist die Skalierbarkeit: Ziel ist es, sicherzustellen dass unser Ansatz effizient einsetzbar ist. Hierbei haben wir insbesondere Techniken zur Optimierung von Prolog Programmen entwickelt, deren Einsatzmöglichkeiten nicht nur auf unseren Ansatz beschränkt sind. Desweiteren haben wir eine umfangreiche Evaluation unseres Ansatzes durchgeführt. Hierbei haben wir die Genauigkeit, Skalierbarkeit sowie die Generizität unseres Ansatzes untersucht. Wir haben gezeigt, dass unser Ansatz für mehrere Arten von Szenarien genau arbeitet und dabei eine gute Skalierbarkeit aufweist. Es hat sich herausgestellt, dass unsere vorgestellten Optimierungen in manchen Fällen sogar zu einer Reduktion von exponentieller zu konstanter Laufzeit führen können.

description: We consider fibrations of genus 2 over complex surfaces. The purpose of this paper is primarily to provide a geometric description of the possible structures of the fibration on a neighborhood of a singular fiber. In particular it is shown that the "geometric data" of the singular fiber determines the fibration on its neighborhood up to a transversely holomorphic $C^{\infty}$-diffeomorphism. The method employed is quite flexible and it applies to good extent to fibrations of arbitrary genus.

description: The popular criteria of optimality for quickest change detection procedures are the Lorden criterion, the Shiryaev-Roberts-Pollak criterion, and the Bayesian criterion. In this paper a robust version of these quickest change detection problems is considered when the pre-change and post-change distributions are not known exactly but belong to known uncertainty classes of distributions. For uncertainty classes that satisfy a specific condition, it is shown that one can identify least favorable distributions (LFDs) from the uncertainty classes, such that the detection rule designed for the LFDs is optimal for the robust problem in a minimax sense. The condition is similar to that required for the identification of LFDs for the robust hypothesis testing problem originally studied by Huber. An upper bound on the delay incurred by the robust test is also obtained in the asymptotic setting under the Lorden criterion of optimality. This bound quantifies the delay penalty incurred to guarantee robustness. When the LFDs can be identified, the proposed test is easier to implement than the CUSUM test based on the Generalized Likelihood Ratio (GLR) statistic which is a popular approach for such robust change detection problems. The proposed test is also shown to give better performance than the GLR test in simulations for some parameter values.

description: We study a type of left-invariant structure on Lie groups, or equivalently on Lie algebras. We introduce obstructions to the existence of a hypo structure, namely the 5-dimensional geometry of hypersurfaces in manifolds with holonomy SU(3). The choice of a splitting g^*=V_1 + V_2, and the vanishing of certain associated cohomology groups, determine a first obstruction. We also construct necessary conditions for the existence of a hypo structure with a fixed almost-contact form. For non-unimodular Lie algebras, we derive an obstruction to the existence of a hypo structure, with no choice involved. We apply these methods to classify solvable Lie algebras that admit a hypo structure.

description: We report the discovery of 44.7 ms pulsations from the X-ray source CXOU J181335.1-174957 using data obtained with the XMM-Newton Observatory. PSR J1813-1749 lies near the center of the young radio supernova remnant G12.82-0.02, which overlaps the compact TeV source HESS J1813-178. This rotation-powered pulsar is the second most energetic in the Galaxy, with a spin-down luminosity of Edot = (6.8 +/- 2.7)E37 erg/s. In the rotating dipole model, the surface dipole magnetic field strength is B_s = (2.7 +/- 0.6)E12 G and the spin-down age of 3.3-7.5 kyr, consistent with the location in the small, shell-type radio remnant. At an assumed distance of 4.7 kpc by association with an adjacent young stellar cluster, the efficiency of PSR J1813-1749 in converting spin-down luminosity to radiation is approx. 0.03% for its 2-10 keV flux, approx. 0.1% for its 20-100 keV INTEGRAL flux, and approx. 0.07% for the >200 GeV emission of HESS J1813-178, making it a likely power source for the latter. The nearby young stellar cluster is possibly the birthplace of the pulsar progenitor, as well as an additional source of seed photons for inverse Compton scattering to TeV energies.

The palaeobiogeographical significance of the Silurian and Devonian trilobites of Japan

Publisher: name: University of Leicester
Year: 2022
Subjects: Uncategorized

description: Trilobites are widely represented in Siluro-Devonian strata of the South Kitakami, Hida Gaien and Kurosegawa Paleozoic terranes of Japan. This thesis presents a detailed systematic palaeontology of four groups of these trilobites: the Proetida (and Aulacopleurida), the Phacopidae, and the Encrinurinae. Proetids are represented by twelve species within eight genera, with three species under open nomenclature, and a single species of aulacopleurid; phacopids by six species – two in open nomenclature; and encrinurids by ten species within three genera, including three described under open nomenclature, and one new species.A palaeobiogeographical analysis of the Siluro-Devonian trilobites of Japan is presented, including six groups with detailed recent systematic analysis – the Proetida, Aulacopleurida, Phacopidae and Encrinurinae analysed herein – and the Illaenidae and Scutelluidae. It also presents preliminary palaeogeographical data on Japanese Siluro-Devonian trilobite groups that are less well-studied, the Cheiruridae, Calymenidae, Lichidae and Odontopleuridae.In terms of palaeogeographical signature, Silurian illaenids and scutelluids show generic and species links with the Australian part of the Gondwana palaeocontinent, but not – apparently – between the three Japanese terranes. By contrast, Silurian encrinurids appear to exhibit a pan-tropical signature. Devonian phacopids, and possibly proetids, suggest generic-level links with the North China palaeocontinent, Devonian cheirurids and calymenids suggest generic-level links South China and Australia, and Devonian lichids strong generic links with Australia.The disparity in biogeographical connections of different groups may in part reflect the fragmentary biostratigraphical record of Japanese trilobites, but also appears to reflect their lithofacies ranges and palaeoecology. This cautions against their use for palaeobiogeographical assessment without a more complete understanding of their palaeoenvironmental context.The Silurian and Devonian trilobites of Japan also have biostratigraphic significance, particularly in the Devonian, where trilobite biostratigraphy, along with detrital zircon geochronology, effectively constrains the age of the Naidaijin and Nakazato formations of the Kurosegawa and South Kitakami terranes respectively.
EFFECT OF INTERVAL SPRINTING ON SELECTED SPEED RELATED VARIABLES AMONG COLLEGE MEN STUDENTS

description: The purpose of the study was designed to examine the effect of interval sprinting on average speed and speed endurance among college men students.  For the purpose of the study, thirty college men students from Dr. Sivanthi Aditanar College of Physical Education, Tiruchendur, Tamilnadu, India were selected as subjects.  They were divided into two equal groups.  each group consisted of fifteen subjects.  Group I underwent interval sprinting for three days per week for twelve weeks.  Group II acted as control who did not undergo any special training programme apart from their regular physical education programme. The following variables, namely average speed and speed endurance were selected as criterion variables.  All the subjects of the two groups were tested on selected dependent variables namely average speed and speed endurance by using 50 mts run and 150 mts run at prior to and immediately after the training programme.

The analysis of covariance was used to analyze the significant difference if any among the groups. The .05 level of confidence was fixed as the level of significance to test the ‘F’ ratio obtained by the analysis of covariance, which was considered appropriate. The results of the study showed that there was a significant difference between interval sprinting group and control group on average speed and speed endurance. And also, it was found that there was a significant improvement on selected criterion variables such as average speed and speed endurance due to interval sprinting.

We conjecture that this relation holds non-perturbatively and at arbitrarily high energy.

description: In the summer of 2019, preliminary archaeological investigations were performed at the North Courtyard group of Las Abejas. The site represents a middle-level settlement unit within the cultural landscape of the Three Rivers Region. The North Courtyard group comprises five residential structures situated at the northernmost margin of the site. While previous work was performed on the site, there is very little information regarding the formation and occupation of this group. Excavations were undertaken within the center of the courtyard and each of the surrounding structures with the intention of providing a meaningful understanding of the role of the group’s occupants relative to the rest of the site. The purpose of this report is to present the data collected and to begin to define the social organization of the site at a local scale.

For proper submersions (with smooth fibres) we construct a push-forward map in differential equivariant K-theory. Finally, we construct a non-degenerate intersection pairing with values in C/Z for the subclass of smooth orbifolds which can be written as global quotients by a finite group action. We construct a real subfunctor of our theory, where the pairing restricts to a non-degenerate R/Z-valued pairing.

description: We investigated the relationship between supermassive black hole (SMBH) mass and host starburst luminosity in Seyfert galaxies and Palomar-Green QSOs, focusing on the host galaxy morphology. Host starburst luminosity was derived from the 11.3 micron polycyclic aromatic hydrocarbon luminosity. We found that the SMBH masses of elliptical-dominated host galaxies are more massive than those of disk-dominated host galaxies statistically. We also found that the SMBH masses of disk-dominated host galaxies seem to be suppressed even under increasing starburst luminosity. These findings imply that final SMBH mass is strongly regulated by host galaxy morphology. This can be understood by considering the radiation drag model as the SMBH growth mechanism, taking into account the radiation efficiency of the host galaxy.

Catch-22 : man in an alien society
Creators: name: Barbour, Michael McKay
Publisher: name: University of British Columbia
Year: 2011

description: This paper examines social relationships and pressures of contemporary society as shown in Joseph Heller's novel Catch-22. Through a brief study of conceptual limitations within Heller's characters it demonstrates that they exist within a totally self-enclosed system divorced from reality but supported by complex justifications. Within this social matrix is seen the heroic strivings of Yossarian to save a world he believes to have gone mad. As the study progresses, it shows that Yossarian and his friends do not in fact share the same conceptual basis as their apparent society. Their satiric efforts are seen to be useless to a society convinced of its own justifications for evil, and destructive to their own potentialities for human-beingness. The ultimate goal of society is seen to be a physical and spiritual fascism in which no dissent is possible. Escape and death are shown to be the true alternatives for those who would maintain their individuality and ethics.

Since, after conscripting the Indian Constitution, the Indian Laws also address and obey the guidelines for human rights and environmental safety laws. Well, the Indian personal laws are fair to everyone, equal to every religion, adhere the things own specific with the laws and regulate the Hindu, Muslims, Sikhs, Christians and follows all the religion with utmost respect. Ancient India was represented traditional law and had historical legal practice which appeared as the institution in different states of India where irrespective culture and tradition treated and embodied religious charters to exchange temporary and semi-permanent characters.

description: This paper reviews and analyses methods used to identify neighbours in 6D space and estimate the corresponding phase-space density. It compares SPH methods to 6D Delaunay tessellation on statical and dynamical realisation of single halo profiles, paying attention to the unknown scaling, S_G, used to relate the spatial dimensions to the velocity dimensions. The methods with local adaptive metric provide the best phase-space estimators. They make use of a Shannon entropy criterion combined with a binary tree partitioning and with SPH interpolation using 10-40 neighbours. Local scaling implemented by such methods, which enforces local isotropy of the distribution function, can vary by about one order of magnitude in different regions within the system. It presents a bimodal distribution, in which one component is dominated by the main part of the halo and the other one is dominated by the substructures. While potentially better than SPH techniques, since it yields an optimal estimate of the local softening volume (and the local number of neighbours required to perform the interpolation), the Delaunay tessellation in fact poorly estimates the phase-space distribution function. Indeed, it requires, the choice of a global scaling S_G. We propose two methods to estimate S_G that yield a good global compromise. However, the Delaunay interpolation still remains quite sensitive to local anisotropies in the distribution. We also compare 6D phase-space density estimation with the proxy, Q=rho/sigma^3, where rho is the local density and 3 sigma^2 is the local 3D velocity dispersion. We show that Q only corresponds to a rough approximation of the true phase-space density, and is not able to capture all the details of the distribution in phase-space, ignoring, in particular, filamentation and tidal streams.

description: This article aims at reengineering of PDF-based complex documents, where specifications of the Object Management Group (OMG) are our initial targets. Our motivation is that such specifications are dense and intricate to use, and tend to have complicated structures. Our objective is therefore to create an approach that allows us to reengineer PDF-based documents, and to illustrate how to make more usable versions of electronic documents (such as specifications, technical books, etc) so that end users to have a better experience with them. The first step was to extract the logical structure of the document in a meaningful XML format for subsequent processing. Our initial assumption was that, many key concepts of a document are expressed in this structure. In the next phase, we created a multilayer hypertext version of the document to facilitate browsing and navigating. Although we initially focused on OMG software specifications, we chose a general approach for different phases of our work including format conversions, logical structure extraction, text extraction, multilayer hypertext generation, and concept exploration. As a consequence, we can process other complex documents to achieve our goals.

description: While being invented for precision measurement of single atomic transitions, frequency combs have also become a versatile tool for broadband spectroscopy in the last years. In this paper we present a novel and simple approach for broadband spectroscopy, combining the accuracy of an optical fiber-laser-based frequency comb with the ease-of-use of a tunable external cavity diode laser. This scheme enables broadband and fast spectroscopy of microresonator modes and allows for precise measurements of their dispersion, which is an important precondition for broadband optical frequency comb generation that has recently been demonstrated in these devices. Moreover, we find excellent agreement of measured microresonator dispersion with predicted values from finite element simulations and we show that tailoring microresonator dispersion can be achieved by adjusting their geometrical properties.
Particles and motion in Spinoza's physics

description: The central aim of my thesis is to enquire into Spinoza's theory of the structure of the physical universe. It is generally accepted that from a scientific point of view Spinoza regarded the universe as consisting of particles in motion. My major concern is with the nature of these particles and what role they play in his cosmology. My basic method of enquiry is to consider, as far as this is possible, Spinoza's statements about the structure of matter as a scientific theory, a system of physics. Chapter Two is a brief survey of Spinoza's scientific activities, by way of providing background. In Chapter Three I explore the physical theory presented in Part Two of the Principles of Cartesian Philosophy with particular emphasis on the basic premisses of that theory, and the problems arising from those basic premisses. In Chapters Four, Five, and Six, the physical theory of the Ethics is discussed, with particular attention to Spinoza's theory of individuals and his ideas on motion. Chapter Seven is a fairly detailed discussion of the nature of the simplest bodies in Spinoza's system. Chapter Eight is a discussion of Spinoza's concept of the universe as a system composed of particles in motion, with particular emphasis on his ideas on the continuum. My major conclusion is that as far as scientific explanation is concerned, the Spino-zistic physics is very similar to the Cartesian physics as presented in the Principles of Cartesian Philosophy. This conclusion is based on five considerations: (1) the general character of the physics of the Ethics is quite compatible with the Cartesian physics with one apparent exception: I give an explanation of this apparent discrepancy; (2) Spinoza's deep concern with the problems of the continuum can only be explained if the basic premisses of his physics are the same as that of the Cartesian physics; (3) the same applies to his denial of the existence of the vacuum; (4) there is nothing that indicates that Spinoza's scientific method if radically different from that underlying the Principles of Cartesian Philosophy; (5) the one instance of Spinoza's outrightly condemning the Cartesian physics is based on a fundamental metaphysical issue and has no direct bearing on that physics qua physics. The major implication of my conclusion is that many of Spinoza's points of doctrine cannot be fully understood unless they are interpreted in the context of the Cartesian cosmology.

description: In renal transplantation, complement is involved in ischemia reperfusion injury, graft rejection and dysfunction. However, it is still unclear how induction of complement and its activation are initiated. Using allograft biopsies of a well-characterized cohort of 28 renal transplant patients with no rejection (Ctrl), delayed graft function (DGF), acute T-cell-mediated (TCMR) or antibody-mediated rejection (ABMR) we analyzed differences in complement reaction. For that mRNA was isolated from FFPE sections, quantified with a multiplex gene expression panel and correlated with transplant conditions and follow-up of patients. Additionally, inflammatory cells were quantified by multiplex immunohistochemistry. In allograft biopsies with TCMR and ABMR gene expression of C1QB was 2-4 fold elevated compared to Ctrl. In TCMR biopsies, mRNA counts of several complement-related genes including C1S, C3, CFB and complement regulators CFH, CR1 and SERPING1 were significantly increased compared to Ctrl. Interestingly, expression levels of about 75% of the analyzed complement related genes correlated with cold ischemia time (CIT) and markers of inflammation. In conclusion, this study suggest an important role of complement in transplant pathology which seems to be at least in part triggered by CIT. Multiplex mRNA analysis might be a useful method to refine diagnosis and explore new pathways involved in rejection.

description: The gauge invariant degrees of freedom of matrix models based on an N x N complex matrix, with U(N) gauge symmetry, contain hidden free particle structures. These are exhibited using triangular matrix variables via the Schur decomposition. The Brauer algebra basis for complex matrix models developed earlier is useful in projecting to a sector which matches the state counting of N free fermions on a circle. The Brauer algebra projection is characterized by the vanishing of a scale invariant laplacian constructed from the complex matrix. The special case of N=2 is studied in detail: the ring of gauge invariant functions as well as a ring of scale and gauge invariant differential operators are characterized completely. The orthonormal basis of wavefunctions in this special case is completely characterized by a set of five commuting Hamiltonians, which display free particle structures. Applications to the reduced matrix quantum mechanics coming from radial quantization in N=4 SYM are described. We propose that the string dual of the complex matrix harmonic oscillator quantum mechanics has an interpretation in terms of strings and branes in 2+1 dimensions.

Quantification of tectonic controls on the distribution and architecture of deep-water facies during the growth of the toe-thrusts region of the Niger Delta
Creators: name: Pizzi, Marco
Publisher: name: Imperial College London

description: Using 3D seismic data, the deep-water fold and thrust belt of the southern lobe of the Niger Delta has been investigated over an area of 4500 km2 to document, for the first time, the detailed growth history of a thrust array and how it controlled the distribution and architecture, through time, of the coeval deep-water sedimentary systems. Quantification of the growth of each structure has been achieved using line-length balancing and yielded measures of cumulative shortening and strain, and their evolving rates, along and across strike and through time. This has enabled a new model for thrust growth to be proposed and linked to the observed change in stratigraphic architecture. The results show that all thrusts nucleated coevally in the study area as small segments, deforming at low strain rates, which caused the deflection of early leveed channels. The progressive lateral propagation and linkage of the segments, along with an increase in strain rates, caused the spatial restriction of the slope channels, until it induced the deposition of ponded lobes and the alteration of the channel architectures into erosional forms. The later decrease in strain rates and smoothing of the topography linked to the deposition of channelized sheets within shallow-ponded basins. These observations lead to the development of a predictive facies model where the occurrence of a specific facies (the architecture) is explained depending on when and where (along strike) a channel (or flow) interacts with a given fold. The specific location where channels cross structures, in turn, is dictated by how deformation is partitioned between structures across-strike, and by the particular distribution of strain rates along-strike. Distribution and architecture are effectively two linked variables which depend on a set of evolving parameters during the growth of a thrust array; the cumulative strain, strain rates and degree of fault linkage.
