Given a finite dimensional special biserial algebra A with normed basis we obtain the dimension formulae of the first Hochschild homology groups of A and the vector space Alt(DA). As a consequence, an explicit dimension formula of the first Hochschild cohomology group of trivial extension TA = A × DA in terms of the combinatorics of the quiver and relations is determined.

Let G be a discrete group and (G,G+) an ordered group. Let (G,GF) be the minimal quasiordered group containing (G,G+). Let TG+ (G) and TGF (G) be the corresponding Toeplitz algebras,and γGF,G+ the natural C*-algebra morphism from TG+ (G) to TGF(G). This paper studies the connection between Ker γGF'G+ and the minimal closed ideal of TG+ (G). It is proved that if G is amenable and GF ≠ G+,then Ker γGF'G+ is exactly the minimal closed non-trivial ideal of TG+ (G). As an application,in the last part of this paper,a character of K-groups of Toeplitz algebras on ordered groups is clarified.

This article analyzes narratives of violence based on interviews with 43 marginalized young Danish people. Their narratives reveal that violence is not only experienced as singular, dramatic encounters; violence is also trivialized in their everyday lives. By drawing on anthropological perspectives...... on everyday violence, we propose a sensitizing framework that enables the exploration of trivialized violence. This framework integrates three perspectives on the process of trivialization: the accumulation of violence; the embodiment of violence; and the temporal and spatial entanglement of violence....... This analysis shows how multiple experiences of violence—as victim, witness, or perpetrator—intersect and mutually inform each other, thereby shaping the everyday lives and dispositions of the marginalized youth. The concept of trivialized violence is a theoretical contribution to cultural and narrative...

Full Text Available A graph $G$ is \\emph{trivially perfect} if for every induced subgraph the cardinality of the largest set of pairwise nonadjacent vertices (the stability number $\\alpha(G$ equals the number of (maximal cliques $m(G$. We characterize the trivially perfect graphs in terms of vertex-coloring and we extend some definitions to infinite graphs.
Amenable, transitive and faithful actions of groups acting on trees
Fima, Pierre
2012-01-01
We study under which condition an amalgamated free product or an HNN-extension over a finite subgroup admits an amenable, transitive and faithful action on an infinite countable set. We show that such an action exists if the initial groups admit an amenable and almost free action with infinite orbits (e.g. virtually free groups or infinite amenable groups). Our result relies on the Baire category Theorem. We extend the result to groups acting on trees.
Beyond formal groups: neighboring acts and watershed protection in Appalachia
Directory of Open Access Journals (Sweden)
Heather Lukacs
2016-09-01
Full Text Available This paper explores how watershed organizations in Appalachia have persisted in addressing water quality issues in areas with a history of coal mining. We identified two watershed groups that have taken responsibility for restoring local creeks that were previously highly degraded and sporadically managed. These watershed groups represent cases of self-organized commons governance in resource-rich, economically poor Appalachian communities. We describe the extent and characteristics of links between watershed group volunteers and watershed residents who are not group members. Through surveys, participant observation, and key-informant consultation, we found that neighbors – group members as well as non-group-members – supported the group's function through informal neighboring acts. Past research has shown that local commons governance institutions benefit from being nested in supportive external structures. We found that the persistence and success of community watershed organizations depends on the informal participation of local residents, affirming the necessity of looking beyond formal, organized groups to understand the resources, expertise, and information needed to address complex water pollution at the watershed level. Our findings augment the concept of nestedness in commons governance to include that of a formal organization acting as a neighbor that exchanges informal neighboring acts with local residents. In this way, we extend the concept of neighboring to include interactions between individuals and a group operating in the same geographic area.
Becoming Trivial: The Book Trailer

Kati Voigt

Full Text Available Despite the introduction of audiobooks and e-books, printed stories still are in high demand. However, in a globalized world which is more and more ruled by mass media and technology, it is increasingly difficult for writers and publishers to promote their books. The solution is almost ironic: popular media, which is assumed to decrease readership, is turned into a tool to increase the number of readers. In 2002 the book trailer emerged as a new web-based marketing strategy for the launch of new books. Since then the appearance of the book trailer has changed considerably. The article examines specific examples and highlights methods that establish the relationship between the content of the book and its representation in the book trailer. Although guidelines apply for the production of book trailers, such as constraints relating to time and content, there are no limitations for the imagination of the producers. A book trailer may be simple, supported only by music and pictures, but they may also be as complex as short films. Additionally, book trailers are not limited to the promotion of one specific genre or age group. Depending on the viral potential of social networks such as YouTube, Facebook, and Tumblr book trailers reach a global audience and, therefore, open up new markets. It can be argued, while book trailers have not yet reached the realm of the everyday, they will gradually come to the attention of academics and this article wants to present a starting point for this development.
Differences in evolutionary pressure acting within highly conserved ortholog groups
Directory of Open Access Journals (Sweden)
Aravind L
2008-07-01
Full Text Available Abstract Background In highly conserved widely distributed ortholog groups, the main evolutionary force is assumed to be purifying selection that enforces sequence conservation, with most divergence occurring by accumulation of neutral substitutions. Using a set of ortholog groups from prokaryotes, with a single representative in each studied organism, we asked the question if this evolutionary pressure is acting similarly on different subgroups of orthologs defined as major lineages (e.g. Proteobacteria or Firmicutes. Results Using correlations in entropy measures as a proxy for evolutionary pressure, we observed two distinct behaviors within our ortholog collection. The first subset of ortholog groups, called here informational, consisted mostly of proteins associated with information processing (i.e. translation, transcription, DNA replication and the second, the non-informational ortholog groups, mostly comprised of proteins involved in metabolic pathways. The evolutionary pressure acting on non-informational proteins is more uniform relative to their informational counterparts. The non-informational proteins show higher level of correlation between entropy profiles and more uniformity across subgroups. Conclusion The low correlation of entropy profiles in the informational ortholog groups suggest that the evolutionary pressure acting on the informational ortholog groups is not uniform across different clades considered this study. This might suggest "fine-tuning" of informational proteins in each lineage leading to lineage-specific differences in selection. This, in turn, could make these proteins less exchangeable between lineages. In contrast, the uniformity of the selective pressure acting on the non-informational groups might allow the exchange of the genetic material via lateral gene transfer.
A non-trivial mixing of electromagnetic and gravitational forces
Aldaya, V; Guerrero, J
2001-01-01
The minimal coupling principle is revisited in a group-cohomological setting. Promoting space-time translations to a "local" symmetry of the Lagrangian of the free particle once the ``kinematical'' symmetry group (either Galilei or Poincare) has been centrally extended by U(1) results in a new electromagnetic force of pure gravitational origin. This constitutes a preliminary attempt to a non-trivial mixing of space-time and internal gauge symmetries and/or interactions.

Non-trivial exponents in coarsening phenomena
Derrida, B.
1997-02-01
One of the simplest examples of stochastic automata is the Glauber dynamics of ferromagnetic spin models such as Ising or Potts models. At zero temperature, if the initial condition is random, one observes a pattern of growing domains with a characteristic size which increases with time like t {1}/{2}. In this self-similar regime, the fraction of spins which never flip up to time t decreases like t- θ where the exponent θ is non-trivial and depends both on the number q of states of the Potts model and on the dimension of space. This exponent can be calculated exactly in one dimension. Similar non-trivial exponents are also present in even simpler models of coarsening, where the dynamical rule is deterministic.
A classical cosmological model for triviality
Salehi, H; Rashidi, R
2004-01-01
The aim of this paper is to study the triviality of $\\lambda\\phi^{4}$ theory in a classical gravitational model. Starting from a conformal invariant scalar tensor theory with a self-interaction term $\\lambda\\phi^{4}$, we investigate the effect of a conformal symmetry breaking emerging from the gravitational coupling of the large-scale distribution of matter in the universe. Taking in this cosmological symmetry breaking phase the infinite limit of the maximal length (the size of the universe) and the zero limit of the minimal length (the Planck length) implies triviality, i.e. a vanishing coupling constant $\\lambda$. It suggests that the activity of the self-interaction term $\\lambda\\phi^{4}$ in the cosmological context implies that the universe is finite and a minimal fundamental length exists.
On Complex Supermanifolds with Trivial Canonical Bundle
Groeger, Josua
2016-01-01
We give an algebraic characterisation for the triviality of the canonical bundle of a complex supermanifold in terms of a certain Batalin-Vilkovisky superalgebra structure. As an application, we study the Calabi-Yau case, in which an explicit formula in terms of the Levi-Civita connection is achieved. Our methods include the use of complex integral forms and the recently developed theory of superholonomy.

Let A be a finite-dimensional algebra over an algebraically closed field. An indecomposable (right) ,4-module M is called generic provided M is infinite k-dimensional but finite length as (left) EndA(M)-module. Let R = A DA be the trivial extension algebra of A- Generic R-modules are constructed from generic A-modules using some functors between Mod A and Mod R. it is also proved that if A is a tame hereditary algebra, then R has only two generic modules.
Non-trivial topologies in quantum gravity
Hawking, S. W.
1984-09-01
This paper examines recent objections to the proposal that topologically non-trivial metrics could cause pure quantum states to decay into mixed states. It is shown that the Kaluza-Klein examples proposed by Gross in which this did not happen are special cases and that there are other Kaluza-Klein metrics in which it does. The objections of Banks, Peskin and Susskind about energy and momentum conservation arise because they assume that the evolution of density operator can be localized to a few Planck lengths. However, it is shown that energy and momentum are conserved only because of the asymptotic field equations and that this requires a large asymptotic region.
Trivial Lagrangians in the Causal Approach
Grigore, Dan-Radu
2015-01-01
We prove the non-uniqueness theorem for the chronological products of a gauge model. We use a cohomological language where the cochains are chronological products, gauge invariance means a cocycle restriction and coboundaries are expressions producing zero sandwiched between physical states. Suppose that we have gauge invariance up to order n of the perturbation theory and we modify the first-order chronological products by a coboundary (a trivial Lagrangian). Then the chronological products up to order n get modified by a coboundary also.
Seifert fibered homology spheres with trivial Heegaard Floer homology
Eftekhary, Eaman
2009-01-01
We show that among Seifert fibered integer homology spheres, Poincare sphere (with either orientation) is the only non-trivial example which has trivial Heegaard Floer homology. Together with an earlier result, this shows that if an integer homology sphere has trivial Heegaard Floer homology, then it is a connected sum of a number of Poincare spheres and hyperbolic homology spheres.
Higgs Mass Triviality Bounds on F(4) Lattices
Klomfass, Markus
In order to accurately describe the cutoff dependence of the Higgs mass triviality bound, the varphi ^4 theory is formulated on an F_4 lattice which preserves Lorentz invariance to a higher degree than the commonly used hypercubic lattice. We solve this model non-perturbatively by evaluating the linked cluster expansion through 12th order following the approach of Luscher and Weisz. The results are continued across the transition line into the broken phase by integrating the perturbative renormalization group equations. In the Goldstone phase, the renormalized coupling never exceeds 2/3 of the tree level unitarity bound when Lambda /m_{R}>= 2. Our results confirm recent Monte Carlo data and we obtain as an upper bound for the Higgs mass m_{R }/f_pi=2.45(7) at Lambda/m_{R }=2. Attempting to produce a heavier Higgs on the lattice, additional four-derivative terms are introduced in the naive action which serve to parameterize the leading order cutoff effects. Using a cluster reflection algorithm of the Swendsen-Wang-Wolff type, we simulate this action on an F_4 lattice in a region where the region where the effects of the new terms are expected to be maximal. As an upper bound we now obtain M _sigma/f_pi~ 2.8, an increase of about 20% compared to the simplest non-linear action. Despite triviality, the scalar sector may thus not be weakly interacting.
The Chow Motive of a Locally Trivial Fibration
Pompeyo-Gutiérrez, Carlos
2012-01-01
Guillet and Soul\\'e have shown that, for a fibration $\\pi: Y \\to X$ with fibre $Z$, locally trivial in the Zariski topology, we have a decomposition \\[ [Y] = [X] \\cdot [Z], \\] where $[\\cdot]$ denotes a class in the Grothendieck group $K_{0}(\\cl{M}_{Rat}(k))$ associated to the category of (pure effective) Chow motives $\\cl{M}_{Rat}(k)$ for a field $k$. By assuming some additional properties for the fibre $Z$, we construct an explicit isomorphism $h(Y) \\cong h(X) \\otimes h(Z)$ in the category $\\cl{M}_{Rat}(k)$, and we use it to prove, for this type of fibrations, some conjectures disscussed by Murre.

Zeta Functions Of Discrete Groups Acting On Trees
Clair, Bryan; Mokhtari-Sharghi, Shahriar
1999-01-01
This paper generalizes Bass' work on zeta functions for uniform tree lattices. Using the theory of von Neumann algebras, machinery is developed to define the zeta function of a discrete group of automorphisms of a bounded degree tree. The main theorems relate the zeta function to determinants of operators defined on edges or vertices of the tree. A zeta function associated to a non-uniform tree lattice with appropriate Hilbert representation is defined. Zeta functions are defined for infinite...
Quark splitting in non-trivial \\theta-vacuum
Xing, Hongxi; Yuan, Feng
2010-01-01
Quark splitting in non-trivial $\\theta$-vacuum with a given helicity is investigated in pQCD with a modified quark propagator. We found that the quark splitting functions were modified by the presence of a topologically non-trivial QCD background field, though there is no explicit helicity flip associated with the radiative processes. The interaction with the topological non-trivial field leads to the degeneracy of the quark splitting functions for left- and right-handed quarks. Such degeneracy can lead to imbalance of left- and right-handed quarks in quark jet showers. We also discuss phenomenological consequences of such imbalance if there exists non-trivial topological gluon field configuration in heavy-ion collisions.

The purpose of this study is to investigate the relationship among surface acting, mental health, and positive group affective tone. According to the prior theory, this study attempts to establish a comprehensive research framework among these variables, and furthermore tests the moderating effect of positive group affective tone. Data were collected from 435 employees in 52 service industrial companies by questionnaire, and this study conducted multilevel analysis. The results showed that surface acting will negatively affect the mental health. In addition, the positive group affective tone have significant moderating effect on the relationship among surface acting and mental health. Finally, this study discusses managerial implications and highlights future research suggestions.
The non-trivial effects of trivial errors in scientific communication and evaluation
Tüür-Fröhlich, Terje
2016-01-01
Thomson Reuters’ citation indexes i.e. SCI, SSCI and AHCI are said to be “authoritative”. Due to the huge influence of these databases on global academic evaluation of productivity and impact, Terje Tüür-Fröhlich decided to conduct case studies on the data quality of Social Sciences Citation Index (SSCI) records. Tüür-Fröhlich investigated articles from social science and law. The main findings: SSCI records contain tremendous amounts of “trivial errors”, not only misspellings and typos as previously mentioned in bibliometrics and scientometrics literature. But Tüür-Fröhlich's research documented fatal errors which have not been mentioned in the scientometrics literature yet at all. Tüür-Fröhlich found more than 80 fatal mutations and mutilations of Pierre Bourdieu (e.g. “Atkinson” or “Pierre, B. and “Pierri, B.”). SSCI even generated zombie references (phantom authors and works) by data fields’ confusion – a deadly sin for a database producer - as fragments of Patent Laws...

Hyperbolically embedded subgroups and rotating families in groups acting on hyperbolic spaces
Dahmani, F; Osin, D
2017-01-01
The authors introduce and study the notions of hyperbolically embedded and very rotating families of subgroups. The former notion can be thought of as a generalization of the peripheral structure of a relatively hyperbolic group, while the latter one provides a natural framework for developing a geometric version of small cancellation theory. Examples of such families naturally occur in groups acting on hyperbolic spaces including hyperbolic and relatively hyperbolic groups, mapping class groups, Out(F_n), and the Cremona group. Other examples can be found among groups acting geometrically on CAT(0) spaces, fundamental groups of graphs of groups, etc. The authors obtain a number of general results about rotating families and hyperbolically embedded subgroups; although their technique applies to a wide class of groups, it is capable of producing new results even for well-studied particular classes. For instance, the authors solve two open problems about mapping class groups, and obtain some results which are n...
Membership Problem in groups acting freely on Z^n-trees
Nikolaev, Andrey
2011-01-01
Groups acting freely on Z^n-trees (Z^n-free groups) play a key role in the study of non-archimedean group actions. Following Stallings' ideas, we develop graph-theoretic techniques to investigate subgroup structure of Z^n-free groups. As an immediate application of the presented method, we give an effective solution to the Uniform Membership Problem and the Power Problem in Z^n-free groups.
Non-trivial 2+1-Dimensional Gravity
Grigore, D R
2010-01-01
We analyze 2+1-dimensional gravity in the framework of quantum gauge theory. We find that Einstein gravity has a trivial physical subspace which reflects the fact that the classical solution in empty space is flat. Therefore we study massive gravity which is not trivial. In the limit of vanishing graviton mass we obtain a non-trivial massless theory different from Einstein gravity. We derive the interaction from descent equations and obtain the cosmological topologically massive gravity. However, in addition to Einstein and Chern-Simons coupling we need coupling to fermionic ghost and anti-ghost fields and to a vector-graviton field with the same mass as the graviton.

Trivial Low Energy States for Commuting Hamiltonians, and the Quantum PCP Conjecture
Hastings, M B
2012-01-01
We consider whether or not Hamiltonians which are sums of commuting projectors have "trivial" ground states which can be constructed by a local quantum circuit of bounded depth and range acting on a product state. While the toric code only has nontrivial ground states, commuting projector Hamiltonians which are sums of two-body interactions have trivial ground states. We define an "interaction complex" for a Hamiltonian, generalizing the interaction graph, and we show that if this complex can be continuously mapped to a 1-complex using a map with bounded diameter of pre-images then the Hamiltonian has a trivial ground state assuming one technical condition on the Hamiltonian (this condition holds for all stabilizer Hamiltonians, and we also prove the result for all Hamiltonians under an assumption on the 1-complex). While this includes cases considered by Ref., it also includes other Hamiltonians whose interaction complexes cannot be coarse-grained into the case of Ref. One motivation for this is the quantum ...
T-duality trivializes bulk-boundary correspondence
Mathai, Varghese
2015-01-01
Recently we introduced T-duality in the study of topological insulators. In this paper, we study the bulk-boundary correspondence for three phenomena in condensed matter physics, namely, the quantum Hall effect, the Chern insulator, and time reversal invariant topological insulators. In all of these cases, we show that T-duality trivializes the bulk-boundary correspondence.

Two-Level Fingerprinting Codes: Non-Trivial Constructions
Rochanakul, Penying
2011-01-01
We extend the concept of two-level fingerprinting codes, introduced by Anthapadmanabhan and Barg (2009) in context of traceability (TA) codes, to other types of fingerprinting codes, namely identifiable parent property (IPP) codes, secure-frameproof (SFP) codes, and frameproof (FP) codes. We define and propose the first explicit non-trivial construction for two-level IPP, SFP and FP codes.

Grube, M
2004-07-01
We investigated the correlation of belonging to an ethnic cultural minority and nonfatal suicidal acts (suicide attempts), suicidal ideation, and self-injurious behavior in a group of 494 psychiatric inpatients at the time of admission. The frequency of nonfatal suicidal acts was 15.3% in the group of immigrants ( n=111) and 8.9% in the group of German patients. This difference is significant, but the impact of belonging to the immigration group covaries with the impact of female gender and young age (below 45 years). If all three factors come together the risk of suicide attempts increases threefold. In the immigrant group alone, nonfatal suicidal acts were correlated with "transcultural conflicts". In the group of suicide attempters, we tried to assess the risk of suicide with the help of the "suicide risk list" (Pöldinger) and the suicidal intention with the help of the "suicide intention scale" (Pierce). Additionally, we investigated the method of suicide attempts and categorized them into two groups: "hard" and "weak" methods. We did not find any significant difference between immigrants and German patients concerning suicide risk, suicide intention, and choice of the method. Although there are some methodological shortcomings, we interpret our findings as an indication that immigrant inpatients are more involved in managing the additional stress which results from their immigration. Perhaps nonfatal suicidal behavior represents a risky, but insufficient attempt at "solving" transcultural problems in the immigrant group.
Acceptance and commitment group therapy (ACT-G) for health anxiety: a randomized controlled trial.
Eilenberg, T; Fink, P; Jensen, J S; Rief, W; Frostholm, L
2016-01-01
Severe health anxiety is frequent and costly, yet rarely diagnosed or treated. Earlier treatment studies show problems with recruitment, dropout and recovery. In the current study, the authors aimed to test the effect of acceptance and commitment group therapy (ACT-G) compared to waitlist in patients with severe health anxiety. During March 2010 to April 2012, 126 consecutively referred patients meeting research criteria for severe health anxiety were block-randomized (1:1) to ACT-G or a 10 months' waitlist (Clinicaltrials.gov, no. NCT01158430). Patients allocated to ACT-G were treated in seven groups of nine patients between December 2010 and October 2012 and received nine weekly 3-h group sessions and a booster session consisting of ACT techniques. The primary outcome was decided a priori as the mean change in self-reported illness worry on the Whiteley-7 Index (WI) from baseline to 10 months' follow-up. Secondary outcomes were improvement in emotional distress and health-related quality of life at 10 months' follow-up. Intention-to-treat analysis showed a statistically significant mean difference of 20.5 points [95% confidence interval (CI) 11.7-29.4, p accepted by the patients. ACT-G seems feasible, acceptable and effective in treating severe health anxiety.

Magnetic monopoles over topologically non trivial Riemann surfaces
Martin, I
1996-01-01
An explicit canonical construction of monopole connections on non trivial U(1) bundles over Riemann surfaces of any genus is given. The class of monopole solutions depend on the conformal class of the given Riemann surface and a set of integer weights. The reduction of Seiberg-Witten 4-monopole equations to Riemann surfaces is performed. It is shown then that the monopole connections constructed are solutions to these equations.

In this talk, we present three examples of new non-trivial vacuum structures that can occur in supersymmetric field theories, along with explicit models in which they arise. The first vacuum structure is one in which supersymmetry is broken at tree-level in a perturbative theory that also contains a supersymmetry-preserving ground state. Models realizing this structure are uniquely characterized by the fact that no flat directions appear in the classical potential, all vacua appear at finite distances in field space, and no non-perturbative physics is required for vacuum stability. The second non-trivial vacuum structure we discuss consists of large (and even infinite) towers of metastable vacua, and we show that models which give rise to such vacuum towers exhibit a rich set of instanton-induced vacuum tunneling dynamics. Finally, our third new non-trivial vacuum structure consists of an infinite number of degenerate vacua; this leads to a Bloch-wave ground state and a vacuum "band" structure. Models with su...

The context of care in assertive community treatment (ACT) can be precarious and generate ethical issues involving the principles of autonomy and paternalism. This focus group study examined case managers’ situated accounts of moral reasoning. Our findings show how they expressed strong moral...... obligation towards helping the clients. Their moral reasoning reflected a paternalistic position where, on different occasions, the potential benefits of their interventions would be prioritised at the expense of protecting the clients’ personal autonomy. The case managers’ reasoning emphasised situational...
Existence of non-trivial, vacuum, asymptotically simple spacetimes
Chrúsciel, P T
2002-01-01
We construct non-trivial vacuum spacetimes with a global I sup +. The construction proceeds by proving extension results for initial data sets across compact boundaries, adapting the gluing arguments of Corvino and Schoen. Another application of the extension results is the existence of initial data which are exactly Schwarzschild both near infinity and near each of the connected component of the apparent horizon. Finally, the construction allows one to add Einstein-Rosen bridges to time-symmetric initial data sets at points satisfying a local parity condition, with the perturbation of the metric localized in an arbitrarily small neighbourhood of the bridge.

Acceptance and Commitment Group Therapy (ACT-G) for health anxiety.
Eilenberg, Trine
2016-10-01
Health anxiety is prevalent (5-9%) in all healthcare settings and in the general population, may have an early onset, and a poor prognosis is seen in severe cases if untreated. Research shows that health anxiety is rarely diagnosed though it causes great suffering for the individual and constitutes a substantial socio-economic burden. Studies have shown that individual cognitive behavioural therapy can relieve health anxiety, but these studies are affected by methodological problems, among others, struggling with patients declining participation, high dropout rates, and some patients not responding to the treatment. Moreover, the impact of health anxiety on sick leave is only scarcely examined. This thesis examines the effect of a new treatment approach, group-based Acceptance & Commitment Therapy (ACT-G) for patients with severe health anxiety in an uncontrolled pilot study and a randomised controlled study (RCT) on ACT-G compared with a 10-month waitlist control condition (paper I and II). Also, the thesis comprises a study on sick leave in patients with health anxiety compared with the general population during a 5-year period and the effect of ACT-G on sick leave. The findings from this study are described in paper III. Patients (age 20-60 years) consecutively referred from general practitioners from Jutland and Funen in the period of March 2010 - April 2012 (approx. 2.5 million citizens) to the Research Clinic for Functional Disorders and Psychosomatics, Aarhus University Hospital, were included. The pilot study included 34 patients, the RCT on ACT-G included 126 patients. In the RCT, patients were block-randomised to either ACT-G and received treatment in 7 groups of each 9 patients in the period of December 2010 - October 2012, or to a 10-month waitlist control group. The primary outcome measure was the Whiteley-7 paper and pencil index for illness worrying. The last paper is based on data on sickness-related benefits from the DREAM social register of
Symmetric functions with non-trivial arity gap
Shtrakov, Sl
2010-01-01
Given an $n$-ary $k-$valued function $f$, $gap(f)$ denotes the essential arity gap of $f$ which is the minimal number of essential variables in $f$ which become fictive when identifying any two distinct essential variables in $f$. The class $G_{p,k}^n$ of all $n$-ary $k-$valued functions $f$ with $2\\leq gap(f)$ is explicitly determined by the authors and R. Willard. We prove that if $f\\in G_{p,k}^n$ is a symmetric function with non-trivial arity gap and $g=f(x_i=c_i)$ is a subfunction of $f$, where $c_i$ is a constant, then $g\\in G_{n-1,k}^{n-1}\\cup G_{2,k}^{n-1}$ or $g$ is a constant function.

Single-field perturbations satisfy an infinite number of consistency relations constraining the squeezed limit of correlation functions at each order in the soft momentum. These can be understood as Ward identities for an infinite set of residual global symmetries, or equivalently as Slavnov-Taylor identities for spatial diffeomorphisms. In this paper, we perform a number of novel, non-trivial checks of the identities in the context of single field inflationary models with arbitrary sound speed. We focus for concreteness on identities involving 3-point functions with a soft external mode, and consider all possible scalar and tensor combinations for the hard-momentum modes. In all these cases, we check the consistency relations up to and including cubic order in the soft momentum. For this purpose, we compute for the first time the 3-point functions involving 2 scalars and 1 tensor, as well as 2 tensors and 1 scalar, for arbitrary sound speed.

Poisson distributions for sharp-time fields antidote for triviality
Klauder, J R
1995-01-01
Standard lattice-space formulations of quartic self-coupled Euclidean scalar quantum fields become trivial in the continuum limit for sufficiently high space-time dimensions, and in particular the moment generating functional for space-time smeared fields becomes a Gaussian appropriate to that of a (possibly generalized) free field. For sharp-time fields this fact implies that the ground-state expectation functional also becomes Gaussian in the continuum limit. To overcome these consequences of the central limit theorem, an auxiliary, nonclassical potential is appended to the original lattice form of the model and parameters are tuned so that a generalized Poisson field distribution emerges in the continuum limit for the ground-state probability distribution. As a consequence, the sharp-time expectation functional is infinitely divisible, but the Hamiltonian operator is such, in the general case, that the generating functional for the space-time smeared field is not infinitely divisible in Minkowski space.

Urinary tract infection (UTI) in children involving renal parenchyma, upper collecting system or bladder is one of the major causes for consideration in the diagnosis and management of paediatric nuclear medicine. Acute pyelonephritis is one of the prime causes of morbidity associated with urinary tract infection in children which can lead to progressive renal damage. Technetium-99m dimercaptosuccinic acid (DMSA) is used extensively for the assessment of UTI in paediatrics. The radiopharmaceutical preparation could be influenced by several factors, most of them are trivial, but invariably have severe impact on the quality of the scintiphotographs. This communication is mainly to highlight some of the issues related to {sup 99}mTc-DMSA preparation and the possible precautionary measures that need to be taken to obviate unwarranted problems.

Dirac Fermions in Non-trivial Topology Black Hole Backgrounds
Gozdz, Marek; Rogatko, Marek
2010-01-01
We discuss the behaviour of the Dirac fermions in a general spherically symmetric black hole background with a non-trivial topology of the event horizon. Both massive and massless cases are taken into account. The analytical studies of intermediate and late-time behaviour of massive Dirac hair in the background of a black hole with a global monopole and dilaton black hole pierced by a cosmic string will be conducted. It was revealed that in the case of a global monopole swallowed by a static black hole the intermediate late-time behaviour depends on the mass of the Dirac field, the multiple number of the wave mode and the global monopole parameter. The late-time behaviour is quite independent of these factors and has the decay rate proportional to $t^{-5/6}$. As far as the black hole pierced by a cosmic string is concerned the intermediate late-time behaviour depends only on the hair mass and the multipole number of the wave mode while the late-time behaviour dependence is the same as in the previous case.

Non-trivial Supersymmetry Correlations between ATLAS and CMS Observations
Li, Tianjun; Nanopoulos, Dimitri V; Walker, Joel W
2012-01-01
We present definite correlations between the CMS 5 \\fb all-hadronic search employing the stransverse mass variable $M_{T2}$ and the ATLAS 5 \\fb all-hadronic and multijet supersymmetry (SUSY) searches, suggesting the possibility that both the ATLAS and CMS experiments are already registering a faint but legitimate SUSY signal at the LHC. We isolate this prospective mutual productivity beyond the Standard Model in the framework of the supersymmetric No-Scale Flipped $SU$(5) grand unified theory, supplemented with extra vector-like matter (flippons). Evident overproduction is observed in three CMS \\mt2 and four ATLAS hadronic and multijet signal regions, where a \\x2 fitting procedure of the CMS 5 \\fb \\mt2 search establishes a best fit SUSY mass in sharp agreement with corresponding ATLAS searches of equivalently heightened signal significance. We believe this correlated behavior across two distinct experiments at precisely the same SUSY mass scale to be highly non-trivial, and potentially indicative of an existi...
Exploring Euclidean Dynamical Triangulations with a Non-trivial Measure Term
Coumbe, Daniel
2014-01-01
We investigate a nonperturbative formulation of quantum gravity defined via Euclidean dynamical triangulations (EDT) with a non-trivial measure term in the path integral. We are motivated to revisit this older formulation of dynamical triangulations by hints from renormalization group approaches that gravity may be asymptotically safe and by the emergence of a semiclassical phase in causal dynamical triangulations (CDT). We study the phase diagram of this model and identify the two phases that are well known from previous work: the branched polymer phase and the collapsed phase. We verify that the order of the phase transition dividing the branched polymer phase from the collapsed phase is almost certainly first-order. The nontrivial measure term enlarges the phase diagram, allowing us to explore a region of the phase diagram that has been dubbed the crinkled region. Although the collapsed and branched polymer phases have been studied extensively in the literature, the crinkled region has not received the sam...
Hecke Transformations of Conformal Blocks in WZW Theory. I. KZB Equations for Non-trivial Bundles
Levin, A; Smirnov, A; Zotov, A
2012-01-01
We describe new families of the Knizhnik-Zamolodchikov-Bernard (KZB) equations related to the WZW-theory corresponding to the adjoint G-bundles over complex curves \\Sigma_{g,n} of genus g with n marked points. The bundles are defined by their characteristic classes - elements of H^2(\\Sigma_{g,n}, Z(G)), where Z(G) is a center of the simple complex Lie group G. The KZB equations are the horizontality condition for the projectively flat connection (the KZB connection) defined on the bundle of conformal blocks over the moduli space of curves. The space of conformal blocks has been known to be decomposed into a few sectors corresponding to the characteristic classes of the underlying bundles. The KZB connection preserves these sectors. In this paper we construct the connection explicitly and prove its flatness for elliptic curves with marked points. For the trivial bundles our construction provides the KZB connection proposed by Felder-Wieczerkowski.

Acceptance and commitment therapy has shown to be effective in chronic pain rehabilitation, and acceptance has been shown to be a key process of change. The influence of treatment dose on acceptance is not clear, and in particular, the effectiveness of a non-intensive treatment (acceptance and commitment therapy (ACT) group program for chronic pain. The study sought to compare, at both groups and individual patient levels, changes in acceptance with changes observed in previous ACT studies. Seventy-one individuals with chronic pain commenced a 9-week ACT-based group program at an outpatient chronic pain service. In addition to acceptance, outcomes included the following: pain catastrophizing, depression, anxiety, quality of life, and pain-related anxiety. To compare the current findings with previous research, effect sizes from seven studies were aggregated using the random-effects model to calculate benchmarks. Reliable change indices (RCIs) were applied to assess change on an individual patient-level. The ACT intervention achieved a statistically significant increase in acceptance and medium effect size (d = 0.54) at a group level. Change in acceptance was of a similar magnitude to that found in previous ACT studies that examined interventions with similar treatment hours (acceptance occurred in approximately one-third (37.2, 90% CI) of patients. Approximately three-quarters (74.3, 90% CI) demonstrated reliable change in at least one of the outcome measures. The low-intensity, group-based ACT intervention was effective at a group level and showed a similar magnitude of change in acceptance to previous ACT studies employing low-intensity interventions. Three-quarters of patients reported reliable change on at least one outcome measure.
Matching curated genome databases: a non trivial task

2008-10-01
Full Text Available Abstract Background Curated databases of completely sequenced genomes have been designed independently at the NCBI (RefSeq and EBI (Genome Reviews to cope with non-standard annotation found in the version of the sequenced genome that has been published by databanks GenBank/EMBL/DDBJ. These curation attempts were expected to review the annotations and to improve their pertinence when using them to annotate newly released genome sequences by homology to previously annotated genomes. However, we observed that such an uncoordinated effort has two unwanted consequences. First, it is not trivial to map the protein identifiers of the same sequence in both databases. Secondly, the two reannotated versions of the same genome differ at the level of their structural annotation. Results Here, we propose CorBank, a program devised to provide cross-referencing protein identifiers no matter what the level of identity is found between their matching sequences. Approximately 98% of the 1,983,258 amino acid sequences are matching, allowing instantaneous retrieval of their respective cross-references. CorBank further allows detecting any differences between the independently curated versions of the same genome. We found that the RefSeq and Genome Reviews versions are perfectly matching for only 50 of the 641 complete genomes we have analyzed. In all other cases there are differences occurring at the level of the coding sequence (CDS, and/or in the total number of CDS in the respective version of the same genome. CorBank is freely accessible at http://www.corbank.u-psud.fr. The CorBank site contains also updated publication of the exhaustive results obtained by comparing RefSeq and Genome Reviews versions of each genome. Accordingly, this web site allows easy search of cross-references between RefSeq, Genome Reviews, and UniProt, for either a single CDS or a whole replicon. Conclusion CorBank is very efficient in rapid detection of the numerous differences existing

A quantum phase transition between a topological and a trivial semi-metal in holography
Landsteiner, Karl; Sun, Ya-Wen
2015-01-01
We present a holographic model of a topological Weyl semi-metal state. Key ingredient is a time-reversal breaking parameter and a mass deformation. Upon varying the ratio of mass to time reversal breaking parameter the model undergoes a quantum phase transition from a topologically non-trivial state to a trivial one. The order parameter for this phase transition is the anomalous Hall effect (AHE). The results can be interpreted in terms of the holographic RG flow leading to restoration of time reversal at the end point of the RG flow in the trivial phase.

After a brief review of critical string theory in trivial backgrounds we begin with introduction to strings in non--trivial backgrounds and noncritical string theory. In particular, we relate the latter to critical string theory in a linear dilaton background. We then show how a black hole background arises from 2D string theory and discuss some of its properties. A time--dependant tachyon background is constructed by perturbing the CFT describing string theory in a linear dilaton background....

It is commonly thought that a state-dependent quantity, after being averaged over a classical ensemble of random Hamiltonians, will always become independent of the state. We point out that this is in general incorrect: if the ensemble of Hamiltonians is time-reversal invariant, and the quantity involves the state in higher than bilinear order, then we show that the quantity is only a constant over the orbits of the invariance group on the Hilbert space. Examples include fidelity and decoherence in appropriate models. (fast track communication)

After the classification of flag-transitive linear spaces,attention has now turned to line-transitive linear spaces.Such spaces are first divided into the point-imprimitive and the point-primitive,the first class is usually easy by the theorem of Delandtsheer and Doyen.The primitive ones are now subdivided,according to the O'Nan-Scotte theorem and some further work by Camina,into the socles which are an elementary abelian or non-abelian simple.In this paper,we consider the latter.Namely,T ≤ G ≤ Aut(T) and G acts line-transitively on finite linear spaces,where T is a non-abelian simple.We obtain some useful lemmas.In particular,we prove that when T is isomorphic to 3D4(q),then T is line-transitive,where q is a power of the prime p.
$AdS_2$ holography is (non-)trivial for (non-)constant dilaton
Grumiller, Daniel; Vassilevich, Dmitri
2015-01-01
We study generic two-dimensional dilaton gravity with a Maxwell field and prove its triviality for constant dilaton boundary conditions, despite of the appearance of a Virasoro algebra with non-zero central charge. We do this by calculating the canonical boundary charges, which turn out to be trivial, and by calculating the quantum gravity partition function, which turns out to be unity. We show that none of the following modifications changes our conclusions: looser boundary conditions, non-linear interactions of the Maxwell field with the dilaton, inclusion of higher spin fields, inclusion of generic gauge fields. Finally, we consider specifically the charged Jackiw--Teitelboim model, whose holographic study was pioneered by Hartman and Strominger, and show that it is non-trivial for certain linear dilaton boundary conditions. We calculate the entropy from the Euclidean path integral, using Wald's method and exploiting the chiral Cardy formula. The macroscopic and microscopic results for entropy agree with ...

We present transport and scanning SQUID measurements on InAs/GaSb double quantum wells, a system predicted to be a two-dimensional topological insulator. Top and back gates allow independent control of density and band offset, allowing tuning from the trivial to the topological regime. In the trivial regime, bulk conductivity is quenched but transport persists along the edges, superficially resembling the predicted helical edge-channels in the topological regime. We characterize edge conduction in the trivial regime in a wide variety of sample geometries and measurement configurations, as a function of temperature, magnetic field, and edge length. Despite similarities to studies claiming measurements of helical edge channels, our characterization points to a non-topological origin for these observations.

Previous studies have supported acceptance and commitment therapy (ACT) for reducing impairment related to various chronic conditions. ACT may possibly be beneficial for bipolar disorder (BD) with co-existing anxiety, which is associated with a poorer treatment outcome. Efforts are needed to identify suitable psychological interventions for BD and co-existing anxiety. In this open clinical trial, we included 26 patients with BD type 1 or 2 at an outpatient psychiatric unit specializing in affective disorders. The intervention consisted of a 12-session manualized group treatment that included psychoeducation, mindfulness, engaging in values-based behaviour, cognitive defusion, acceptance and relapse prevention modules. Participants completed four self-report questionnaires covering anxiety symptoms (Beck Anxiety Inventory - BAI), depressive symptoms (Beck Depression Inventory - BDI-II), quality of life (Quality of Life Inventory - QOLI) and psychological flexibility (Acceptance and Action Questionnaire - AAQ-2) before, during and after the treatment. At post-treatment, the participants reported significant improvements in all outcome measures, with large effects (Cohen's d between 0.73 and 1.98). The mean reduction in anxiety symptoms was 45%. At post-treatment, 96% of the patients were classified as responders on at least one of the outcome measures. A limitation is that the trial is uncontrolled. The results suggest that ACT has the potential to be an effective treatment for BD patients with co-existing anxiety. Further randomized studies are warranted.

We examined predictors of collective action among bystander group members in solidarity with a disadvantaged group by extending the dual pathway model of collective action, which proposes one efficacy-based and one emotion-based path to collective action (Van Zomeren, Spears, Fischer, & Leach, 2004). Based on two proposed functions of social identity performance (Klein, Spears, & Reicher, 2007), we distinguished between the efficacy of collective action at consolidating the identity of a protest movement and its efficacy at achieving social change (political efficacy). We expected identity consolidation efficacy to positively predict collective action tendencies directly and indirectly via political efficacy. We also expected collective action tendencies to be positively predicted by moral outrage and by sympathy in response to disadvantaged outgroup's suffering. These hypotheses were supported in two surveys examining intentions to protest for Palestine in Britain (Study 1), and intentions to attend the June 4th vigil in Hong Kong to commemorate the Tiananmen massacre among a sample of Hong Kong citizens (Study 2). The contributions of these findings to research on the dual pathway model of collective action and the different functions of collective action are discussed.

Full Text Available The article begins with a reflection on performative utterances, which are speech acts, to show that the right contributes to the creation of reality and subjectivity. Based on this argument examines five definitions of the situation of children demobilized from illegal armed groups in Colombia, named according to their effects psychoeducational: victimizing, pathologizing, criminalizing, idealizing and responsabilizing. Each definition is examined in terms of their philosophical affiliation, deterministic, nondeterministic or interactionist, its effects on the construction of the identity of minors and in his appeal to responsibility and legal insanity. At the end of the article shows the intervention proposals arising from each of the definitions and shows the role that restorative justice can play in building a model of care which confers responsibility to the children demobilized from illegal armed groups, and other victims of armed conflict, which guarantees the restitution of rights and also empowers them as key actors in redefining their social role and identity reconstruction.
High mobility group box 1 protein as a late-acting mediator of acute lung inflammation.
Lutz, Waldemar; Stetkiewicz, Jan
2004-01-01
Acute inflammatory lung injury is often a delayed complication of critical illness and is associated with increased mortality. High mobility group box 1 (HMGB1) protein, in addition to its role as a transcriptional regulator factor, has been identified as a late mediator of endotoxin lethality and might be also involved in the development and progression of acute lung injury. HMGB1 protein itself can cause an acute inflammatory response manifested by increased production of proinflammatory cytokines and neutrophil accumulation. The delayed kinetics of HMGB1 protein release indicate that this protein is a distal mediator of acute inflamatory lung injury. Anti-HMGB1 protein antibodies attenuated endotoxin-induced lung injury, but not the early release of TNF-alpha and IL-1beta, indicating that HMGB1 protein is a late mediator of endotoxin-induced acute lung injury. HMGB1 protein is not released by apoptotic cells but is passively released by necrotic or damaged somatic and immune cells and it functions as a major stimulus of necrosis-induced inflammation. HMGB1 protein is also released by activated monocytes/macrophages and induces delayed and biphasic release of proinflammatory mediators from these cells. HMGB1 protein failed to stimulate cytokines release in lymphocytes, indicating that cellular stimulation is specific. We would like to suggest that HMGB1 protein may be also a primary mediator of the inflammatory responses to lung cells injury caused by toxic environmental chemicals.

The crystal structure of HMGB1 box A bound to an unmodified AT-rich DNA fragment is reported at a resolution of 2 Å. A new mode of DNA recognition for HMG box proteins is found in which two box A domains bind in an unusual configuration generating a highly kinked DNA structure. High-mobility group protein 1 (HMGB1) is an essential and ubiquitous DNA architectural factor that influences a myriad of cellular processes. HMGB1 contains two DNA-binding domains, box A and box B, which have little sequence specificity but have remarkable abilities to underwind and bend DNA. Although HMGB1 box A is thought to be responsible for the majority of HMGB1–DNA interactions with pre-bent or kinked DNA, little is known about how it recognizes unmodified DNA. Here, the crystal structure of HMGB1 box A bound to an AT-rich DNA fragment is reported at a resolution of 2 Å. Two box A domains of HMGB1 collaborate in an unusual configuration in which the Phe37 residues of both domains stack together and intercalate the same CG base pair, generating highly kinked DNA. This represents a novel mode of DNA recognition for HMGB proteins and reveals a mechanism by which structure-specific HMG boxes kink linear DNA.

A two-valued fitness landscape is introduced for the classical Eigen's quasispecies model. This fitness landscape can be considered as a direct generalization of the so-called single- or sharply peaked landscape. A general, non-permutation invariant quasispecies model is studied, and therefore the dimension of the problem is [Formula: see text], where N is the sequence length. It is shown that if the fitness function is equal to [Formula: see text] on a G-orbit A and is equal to w elsewhere, then the mean population fitness can be found as the largest root of an algebraic equation of degree at most [Formula: see text]. Here G is an arbitrary isometry group acting on the metric space of sequences of zeroes and ones of the length N with the Hamming distance. An explicit form of this exact algebraic equation is given in terms of the spherical growth function of the G-orbit A. Motivated by the analysis of the two-valued fitness landscapes, an abstract generalization of Eigen's model is introduced such that the sequences are identified with the points of a finite metric space X together with a group of isometries acting transitively on X. In particular, a simplicial analog of the original quasispecies model is discussed, which can be considered as a mathematical model of the switching of the antigenic variants for some bacteria.

We study a phi/sub 4//sup 4/ planar euclidean quantum field theory with propagator 1/psup(2-epsilon/2), epsilon > 0. With the help of the tree expansion of Gallavotti and Nicolo, this non-renormalizable theory is shown to have a non-trivial ultraviolet-stable fixed point at negative coupling constant. The vicinity of the fixed point is discussed.

We study a model of opinion formation where the collective decision of group is said to happen if the fraction of agents having the most common opinion exceeds a threshold value, a \\textit{critical mass}. We find that there exists a unique, non-trivial critical mass giving the most efficient convergence to consensus. In addition, we observe that for small critical masses, the characteristic time scale for the relaxation to consensus splits into two. The shorter time scale corresponds to a direct relaxation and the longer can be explained by the existence of intermediate, metastable states similar to those found in [P.\\ Chen and S.\\ Redner, Phys.\\ Rev.\\ E \\textbf{71}, 036101 (2005)]. This longer time-scale is dependent on the precise condition for consensus---with a modification of the condition it can go away.
Quantum weights of monopoles and calorons with non-trivial holonomy
Diakonov, D
2004-01-01
The functional determinant is computed exactly for quantum oscillations about periodic instantons with non-trivial values of the Polyakov line at spatial infinity (or holonomy). Such instantons can be viewed as composed of the Bogomolnyi--Prasad--Sommerfeld (BPS) monopoles or dyons. We find the weight or the probability with which dyons occur in the pure Yang--Mills partition function. It turns out that dyons experience quantum interactions having the familiar "linear plus Coulomb" form but with the "string tension'' depending on the holonomy. We present an argument that at temperatures below the critical one computed from Lambda_QCD, trivial holonomy becomes unstable, with instantons ``ionizing'' into separate dyons. It may serve as a microscopic mechanism of the confinement-deconfinement phase transition.

We provide a set of prescriptions for implementing a quantum circuit model algorithm as measurement based quantum computing (MBQC) algorithm1, 2 via a large cluster state. As means of illustration we draw upon our numerical modeling experience to describe a large graph state capable of searching a logical 8 element list (a non-trivial version of Grover's algorithm3 with feedforward). We develop several prescriptions based on analytic evaluation of cluster states and graph state equations which can be generalized into any circuit model operations. Such a resulting cluster state will be able to carry out the desired operation with appropriate measurements and feed forward error correction. We also discuss the physical implementation and the analysis of the principal 3-qubit entangling gate (Toffoli) required for a non-trivial feedforward realization of an 8-element Grover search algorithm.

The appearance of being scientific can increase persuasiveness. Even trivial cues can create such an appearance of a scientific basis. In our studies, including simple elements, such as graphs (Studies 1-2) or a chemical formula (Study 3), increased belief in a medication's efficacy. This appears to be due to the association of such elements with science, rather than increased comprehensibility, use of visuals, or recall. Belief in science moderates the persuasive effect of graphs, such that people who have a greater belief in science are more affected by the presence of graphs (Study 2). Overall, the studies contribute to past research by demonstrating that even trivial elements can increase public persuasion despite their not truly indicating scientific expertise or objective support. © The Author(s) 2014.
Two-dimensional topological crystalline insulator phase in quantum wells of trivial insulators

2016-06-01
The realization of two-dimensional (2D) topological insulators (TIs) in HgTe/CdTe quantum wells (QWs) has generated an explosion of research on TIs and novel topologically nontrivial phases. Here we predict, based on first-principles calculations, that the newly discovered 2D topological crystalline insulators (TCIs) phase exists even in the QWs of trivial insulators, e.g. (Sn/Pb)Te and Na(Cl/Br), with mirror Chern number {n}{{M}}=-2. Tunable nontrivial energy gaps ranging from 4 to 238 meV are obtained, guaranteeing further room-temperature observations and applications. The combined effect of strain and electrostatic interaction that can be engineered by the cladding layers leads to a band inversion, resulting in the phase transition from trivial insulator to 2D TCIs. Our work provides a new strategy for engineering topological states in 2D materials.
Spinning Particle as a Non-trivial Rotating Super Black Hole with Broken N=2 Supersymmetry
Burinskii, A
1999-01-01
A non-trivial super black hole solution is considered as representing a combined model of the Kerr spinning particle and superparticle. Treatment is based on the broken N=2 supersymmetry in supergravity in analogue with Deser-Zumino model of broken supersymmetry in N=1 supergravity. There appears a non-linear realization of broken supersymmetry, which is very specific for the Kerr geometry and which leads to a family of the exact non-trivial rotating and charged super black hole solutions (super-Kerr-Newman solutions). Peculiarities of the super-Kerr-Newman solutions and in particular the appearance of the short ranging traveling waves of torsion and other fields, build of the nilpotent Grassmann variables, on the pure bosonic Kerr-Newman background are discussed.

Supersymmetric quantum mechanics is constructed in a new non-Hermitian representation. Firstly, the map between the partner operators (±) is chosen antilinear. Secondly, both these components of a super-Hamiltonian $\\mathcal{H}$ are defined along certain topologically non-trivial complex curves r(±)() which spread over several Riemann sheets of the wave function. The non-uniqueness of our choice of the map $\\mathcal{T}$ between `tobogganic' partner curves r(+)() and r(−)() is emphasized.

Triviality of $\\phi^4_4$ in the broken phase revisited
Korzec, Tomasz
2015-01-01
We define a finite size renormalization scheme for $\\phi^4$ theory which in the thermodynamic limit reduces to the standard scheme used in the broken phase. We use it to re-investigate the question of triviality for the four dimensional infinite bare coupling (Ising) limit. The relevant observables all rely on two-point functions and are very suitable for a precise estimation with the worm algorithm. This contribution updates an earlier publication by analysing a much larger dataset.
Triviality of $\\varphi^4$ theory in a finite volume scheme adapted to the broken phase
Siefert, Johannes
2014-01-01
We study the standard one-component $\\varphi^4$-theory in four dimensions. A renormalized coupling is defined in a finite size renormalization scheme which becomes the standard scheme of the broken phase for large volumes. Numerical simulations are reported using the worm algorithm in the limit of infinite bare coupling. The cutoff dependence of the renormalized coupling closely follows the perturbative Callan Symanzik equation and the triviality scenario is hence further supported.

Trivial trauma and delayed rupture of a normal spleen: a case report
Directory of Open Access Journals (Sweden)
Sowers Nicholas
2011-12-01
Full Text Available Abstract Introduction Although a majority of splenic ruptures present acutely with a known mechanism of injury, a minority of patients present days to weeks following trauma with a delayed rupture. Also uncommon is the atraumatic rupture, the vast majority of which occur in patients with underlying splenic pathology. A handful of cases of apparently spontaneous rupture of a normal spleen are reported; however, there is debate about whether these actually represent delayed ruptures following a history of trauma that is not elicited. Although a few cases of delayed rupture of the spleen following trivial trauma have been reported, the majority of these present evidence of an underlying disease process. We found only two such cases that documented a normal spleen and three cases where underlying splenic pathology was not reported. We review the literature and discuss the phenomenon of delayed rupture of the normal spleen following trivial trauma. Case presentation A 27-year-old Caucasian man with no underlying splenic pathology presented with splenic rupture one week after playfully wrestling with his partner. The patient did not present at the time of the injury and only recalled it upon repeated questioning after computed tomography diagnosis. Conclusions This case lends support to the theory that the normal spleen can rupture some time after trivial trauma, which seems like a more plausible explanation than rupture without cause. However, given the dearth of similar reports in the literature, the possibility remains that the association we have observed is not causational.
Non-linear Dynamics in $QED_{3}$ and Non-trivial Infrared Structure
Mavromatos, Nikolaos E
1999-01-01
In this work we consider a coupled system of Schwinger-Dyson equations for self-energy and vertex functions in QED_3. Using the concept of a semi-amputated vertex function, we manage to decouple the vertex equation and transform it in the infrared into a non-linear differential equation of Emden-Fowler type. Its solution suggests the following picture: in the absence of infrared cut-offs there is only a trivial infrared fixed-point structure in the theory. However, the presence of masses, for either fermions or photons, changes the situation drastically, leading to a mass-dependent non-trivial infrared fixed point. In this picture a dynamical mass for the fermions is found to be generated consistently. The non-linearity of the equations gives rise to highly non-trivial constraints among the mass and effective (`running') gauge coupling, which impose lower and upper bounds on the latter for dynamical mass generation to occur. Possible implications of this to the theory of high-temperature superconductivity are...

Replication of Non-Trivial Directional Motion in Multi-Scales Observed by the Runs Test
Yura, Yoshihiro; Ohnishi, Takaaki; Yamada, Kenta; Takayasu, Hideki; Takayasu, Misako
Non-trivial autocorrelation in up-down statistics in financial market price fluctuation is revealed by a multi-scale runs test(Wald-Wolfowitz test). We apply two models, a stochastic price model and dealer model to understand this property. In both approaches we successfully reproduce the non-stationary directional price motions consistent with the runs test by tuning parameters in the models. We find that two types of dealers exist in the markets, a short-time-scale trend-follower and an extended-time-scale contrarian who are active in different time periods.

Full Text Available Introduction: Skull-based osteomyelitis is bony infection which generally originates from inadequately treated chronic infection, adjoining tissue infection or after trauma.Case: 11 month female child had a trivial fall while standing near a bucket. The child developed fracture of right clavicle and left orbital swelling which was inadequately treated. This resulted in in spread of infection to adjoining tissues, skull bones, sinuses and brain.Conclusion: Cranial base osteomyelitis is rare but dreaded condition which requires early diagnosis and prompt treatment to avoid mortality and morbidity in form of neurological deficits and permanent disability

We propose a predictive inert two-Higgs doublet model, where the standard model (SM) symmetry is extended by S{sub 3} x Z{sub 2} x Z{sub 12} and the field content is enlarged by extra scalar fields, charged exotic fermions and two heavy right-handed Majorana neutrinos. The charged exotic fermions generate a non-trivial quark mixing and provide one-loop-level masses for the first- and second-generation charged fermions. The masses of the light active neutrinos are generated from a one-loop-level radiative seesaw mechanism. Our model successfully explains the observed SM fermion mass and mixing pattern. (orig.)
Fermion Condensates and the Trivial Vacuum of Light-Cone Quantum Field Theory
Heinzl, T
1996-01-01
We discuss the definition of condensates within light-cone quantum field theory. As the vacuum state in this formulation is trivial, we suggest to abstract vacuum properties from the particle spectrum. The latter can in principle be calculated by solving the eigenvalue problem of the light-cone Hamiltonian. We focus on fermionic condensates which are order parameters of chiral symmetry breaking. As a paradigm identity we use the Gell-Mann-Oakes-Renner relation between the quark condensate and the observable pion mass. We examine the analogues of this relation in the `t~Hooft and Schwinger model, respectively. A brief discussion of the Nambu-Jona-Lasinio model is added.

Ab initio relativistic band structure calculations are performed for the frequency-dependent spin Hall conductivity of three- (3D), two- (2D) and one-dimensional (1D) materials such as bulk semiconductors, atomically thin crystals, and their nanoribbons. Besides the influence of the dimensionality we also study differences between trivial and topological insulators (TIs). The frequency dependence of the conductivity is governed by the band-structure details, while its static value scales with the spin-orbit interaction in 3D but is quantized in units of e2/h for 2D TIs. 1D topological edge states influence the conductivity mainly for vanishing frequencies.
Trivial symmetries in a 3D topological torsion model of gravity
Banerjee, Rabin; 10.1088/1742-6596/405/1/012028
2012-01-01
We study the gauge symmetries in a Mielke-Baekler type model of gravity in 2+1 dimensions. The model is built in a Poincare gauge theory framework where localisation of Poincare symmetries lead to gravity. However, explicit construction of gauge symmetries in the model through a Hamiltonian procedure yields an apparently different set of symmetries, as has been noted by various authors. Here, we show that the two sets of symmetries are actually equivalent in a canonical sense, their difference being just a set of trivial symmetries.

Mercury ion complexation reactions were carried out between 3 and various mercury(II) salts. 1H NMR studies showed that the role of solvent, the anion chosen and the initial reaction conditions were critical and that the formation of a “simple” mercury(II) complex was non-trivial. The mercury(II) ion can cause either (i) the formation of an ion-pair system, which have a characteristic doubling of all signals in the 1H NMR spectrum, (ii) a cleavage reaction to occur resulting in the reformatio...
Computing a Non-trivial Lower Bound on the Joint Entropy between Two Images
Energy Technology Data Exchange (ETDEWEB)
Perumalla, Kalyan S. [Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States)
2017-03-01
In this report, a non-trivial lower bound on the joint entropy of two non-identical images is developed, which is greater than the individual entropies of the images. The lower bound is the least joint entropy possible among all pairs of images that have the same histograms as those of the given images. New algorithms are presented to compute the joint entropy lower bound with a computation time proportional to S log S where S is the number of histogram bins of the images. This is faster than the traditional methods of computing the exact joint entropy with a computation time that is quadratic in S .
Non-trivial \\theta-Vacuum Effects in the 2-d O(3) Model
Bögli, Michael; Pepe, Michele; Wiese, Uwe-Jens
2011-01-01
We study \\theta-vacua in the 2-d lattice O(3) model using the standard action and an optimized constraint action with very small cut-off effects, combined with the geometric topological charge. Remarkably, dislocation lattice artifacts do not spoil the non-trivial continuum limit at \\theta\\ non-zero, and there are different continuum theories for each value of \\theta. A very precise Monte Carlo study of the step scaling function indirectly confirms the exact S-matrix of the 2-d O(3) model at \\theta = \\pi.
About the triviality of the higher derivative sector in the abelian Lee-Wick model
Fiorentini, D
2016-01-01
Canonical quantization is reviewed here for the Abelian Lee-Wick model by using the Dirac constraints method. New degrees of freedom associated to the (higher derivatives) Lee-Wick ghost are excluded from the (physical) space of observables by a new prescription, based on the Nielsen-type BRST-extended symmetry for the Lee-Wick mass term. We prove that this prescription is nothing but an effective form of implementing the cohomological triviality of the higher-derivative pure sector associated to the existence of a new exclusive higher-derivative BRST symmetry.
Existence of non-trivial, vacuum, asymptotically simple space-times
Chrúsciel, P T; Chrusciel, Piotr T.; Delay, Erwann
2002-01-01
We construct non-trivial vacuum space-times with a global Scri. The construction proceeds by proving extension results across compact boundaries for initial data sets, adapting the gluing arguments of Corvino and Schoen. Another application of the extension results is existence of initial data which are exactly Schwarzschild both near infinity and near each of the connected component of the apparent horizon. Finally the construction allows one to add Einstein-Rosen bridges to time-symmetric initial data sets at points satisfying a local parity condition, with the perturbation of the metric localized in an arbitrarily small neighbourhood of the bridge.

We propose a predictive inert two-Higgs doublet model, where the standard model (SM) symmetry is extended by S3⊗ Z2⊗ Z_{12} and the field content is enlarged by extra scalar fields, charged exotic fermions and two heavy right-handed Majorana neutrinos. The charged exotic fermions generate a non-trivial quark mixing and provide one-loop-level masses for the first- and second-generation charged fermions. The masses of the light active neutrinos are generated from a one-loop-level radiative seesaw mechanism. Our model successfully explains the observed SM fermion mass and mixing pattern.

Multichannel Scattering Problem with Non-trivial Asymptotic Non-adiabatic Coupling
Yakovlev, S L; Elander, N; Belyaev, A K
2016-01-01
The multichannel scattering problem in an adiabatic representation is considered. The non-adiabatic coupling matrix is assumed to have a non-trivial constant asymptotic behavior at large internuclear separations. The asymptotic solutions at large internuclear distances are constructed. It is shown that these solutions up to the first order of perturbation theory are identical to the asymptotic solutions of the re-projection approach, which was proposed earlier as a remedy for the electron translation problem in the context of the Born-Oppenheimer treatment.

Particle propagation in non-trivial backgrounds: a quantum field theory approach
Arteaga, Daniel
2007-01-01
The basic aim of the thesis is the study of the propagation of particles and quasiparticles in non-trivial backgrounds from the quantum field theory point of view. By "non-trivial background" we mean either a non-vacuum state in Minkowski spacetime or an arbitrary state in a curved spacetime. Starting with the case of a flat spacetime, the basic properties of the particle and quasiparticle propagation are analyzed using two different methods other than the conventional mean-field-based techniques: on the one hand, the quantum state corresponding to the quasiparticle excitation is explicitly constructed; on the other hand, the spectral representation of the two-point propagators is analyzed. Both methods lead to the same results: the energy and decay rate of the quasiparticles are determined by the real and imaginary parts of the retarded self-energy respectively. These general results are applied to two particular quantum systems: first, a scalar particle immersed in a thermal graviton bath; second, a simplif...
Classification of trivial spin-1 tensor network states on a square lattice
Lee, Hyunyong; Han, Jung Hoon
2016-09-01
Classification of possible quantum spin liquid (QSL) states of interacting spin-1/2's in two dimensions has been a fascinating topic of condensed matter for decades, resulting in enormous progress in our understanding of low-dimensional quantum matter. By contrast, relatively little work exists on the identification, let alone classification, of QSL phases for spin-1 systems in dimensions higher than one. Employing the powerful ideas of tensor network theory and its classification, we develop general methods for writing QSL wave functions of spin-1 respecting all the lattice symmetries, spin rotation, and time reversal with trivial gauge structure on the square lattice. We find 25 distinct classes characterized by five binary quantum numbers. Several explicit constructions of such wave functions are given for bond dimensions D ranging from two to four, along with thorough numerical analyses to identify their physical characters. Both gapless and gapped states are found. The topological entanglement entropy of the gapped states is close to zero, indicative of topologically trivial states. In D =4 , several different tensors can be linearly combined to produce a family of states within the same symmetry class. A rich "phase diagram" can be worked out among the phases of these tensors, as well as the phase transitions among them. Among the states we identified in this putative phase diagram is the plaquette-ordered phase, gapped resonating valence bond phase, and a critical phase. A continuous transition separates the plaquette-ordered phase from the resonating valence bond phase.
Non-compact Calabi-Yau spaces and other non-trivial backgrounds for 4-d superstrings
Kiritsis, Elias B; Lüst, Dieter
1993-01-01
A large class of new 4-D superstring vacua with non-trivial/singular geometries, spacetime supersymmetry and other background fields (axion, dilaton) are found. Killing symmetries are generic and are associated with non-trivial dilaton and antisymmetric tensor fields. Duality symmetries preserving N=2 superconformal invariance are employed to generate a large class of explicit metrics for non-compact 4-D Calabi-Yau manifolds with Killing symmetries.

Isolated traumatic oculomotor nerve palsy caused by a trivial fall is extremely rare. We report a case of this condition. A 49-year-old woman had distal radius fracture and ptosis on the same side after having a trivial domestic fall. She did not show any clinical or radiological signs of head injury. Computerized tomography revealed a calcified posterior petroclinoid ligament which has direct anatomical and pathological relation with the oculomotor nerve. PMID:25767590
Renormalization of multiple infinities and the renormalization group in string loops
Russo, J.; Tseytlin, A. A.
1990-08-01
There is a widespread belief that string loop massles divergences may be absorbed into a renormalization of σ-model couplings (space-time metric and dilaton). The crucial property for this idea to be consistently implemented to arbitrary order in string loops should be the renormalizability of the generating functional for string amplitudes. We make several non-trivial checks of the renormalizability by explicit calculations at genus 1, 2 and 3. The renormalizability becomes non-trivial at the log 2ɛ order. We show that the log 2 ɛ counterterms are universal (e.g. the same counterterms provide finiteness both of two-loop scattering amplitudes and of the three-loop partition function) and are related to the log ɛ counterterms (β-functions) in the standard way dictated by the renormalization group. This checks the consistency of the Fischler-Susskind mechanism and implies that the renormalization group acts properly at the string loop level.
Magnetic translation groups as group extension
Florek, Wojciech
1998-01-01
Extensions of a direct product T of two cyclic groups Z_n1 and Z_n2 by an Abelian (gauge) group G with the trivial action of T on G are considered. All possible (nonequivalent) factor systems are determined using the Mac Lane method. Some of resulting groups describe magnetic translation groups. As examples extensions with G=U(1) and G=Z_n are considered and discussed.

A Web-Based Version of a Trivial Game to Promote Galician Culture
Luaces, Miguel R.; Pedreira, Oscar; Places, Ángeles S.; Seco, Diego
We present in this paper the architecture and some implementation details of a web-based version of a Trivial game. Our implementation achieves such a high degree of interactivity between the players that they perceive the game as being played in real-time. More importantly, no plug-in or applet is used in the architecture of the system. These properties are achieved by means of a carefully designed architecture that uses AJAX (Asynchronous JavaScript and XML) for data exchange. Using this approach, it is possible to develop any type of web-based collaborative software with few load on the web server. In the paper, we analyze traditional architectures for web-based applications and we show how our approach overcomes their limitations. Furthermore, we proof the efficiency of our approach by means of an empirical comparison.
Non-trivial Inter-layer Degree Correlations in Heterogeneously Growing Multiplex Networks
Fotouhi, Babak
2014-01-01
The multiplex network growth literature has been confined to homogeneous growth hitherto, where the number of links that each new incoming node establishes is the same across layers. This paper focuses on heterogeneous growth. We first analyze the case of two preferentially growing layers and find a closed-form expression for the inter-layer degree distribution, and demonstrate that non-trivial inter-layer degree correlations emerge in the steady state. Then we focus on the case of uniform growth. Surprisingly, inter-layer correlations arise in the random case, too. Also, we observe that the expression for the average layer-2 degree of nodes whose layer-1 degree is k, is identical for the uniform and preferential schemes. Throughout, theoretical predictions are corroborated using Monte Carlo simulations.

Full Text Available A young female presented with blurred vision in the left eye after she rubbed her eye. On examination of both eyes, she had 360° thinning adjacent to the limbus, lipid deposition and superficial vascularization with a perforation in the left eye. The patient was diagnosed with bilateral Terrien′s marginal degeneration (TMD with perforation. Corneal topography of the right eye revealed high oblique astigmatism confirming the diagnosis. A peripheral patch graft was performed for the left eye. At 18 months postoperatively, the best-corrected visual acuity was 20/20 in both eyes. The graft was clear. Topography of right eye was stable, and the left eye had oblique astigmatism. Bilateral advanced TMD in a young patient presenting with corneal perforation following trivial trauma is extremely uncommon. Patch graft may be an option for restoring the globe integrity in such cases. Regular follow-up is necessary as the condition progresses slowly.
Trivial or Commendable? : Women’s Writing, Popular Culture, and Chick Lit
Directory of Open Access Journals (Sweden)
Ryan, Mary
2010-07-01
Full Text Available There are a number of similarities between popular culture and women's writing: both have been dismissed as trivial and worthless, have traditionally received little respect from critics, and have been scorned because of theis apparently "low-brow" appeal. Additionally, both were long excluded from the literary Canon. In contemporary culture, the intersection of popular culture and women's writing takes the form of chick lit, the contemporary genre of fiction starring female characters in their 20s and 30s as they make their way through their lives and tackle all the obstacles in their way. As well as outlining the characteristics and history of chick lit, this paper will discuss the negative reception that popular culture, women's writing, and chick lit has often been subjected to, and will show how studies are now emerging with the aim of demonstrating how such genres may have more worth and potential than is typically suggested.
Topologically non-trivial electronic and magnetic states in doped copper Kagome lattices
Guterding, Daniel; Jeschke, Harald O.; Valenti, Roser
We present a theoretical investigation of doped copper kagome materials based on natural minerals Herbertsmithite [ZnCu3(OH)6Cl2] and Barlowite[Cu4(OH)6FBr]. Using ab-initio density functional theory calculations we estimate the stability of the hypothetical compounds against structural distortions and analyze their electronic and magnetic properties. We find that materials based on Herbertsmithite present an ideal playground for investigating the interplay of non-trivial band-topology and strong electronic correlation effects. In particular, we propose candidates for the Quantum Spin Hall effect at filling 4/3 and the Quantum Anomalous Hall effect at filling 2/3. For the Barlowite system we point out a route to realize a Quantum Spin Liquid.

Effective action of heterotic compactification on K3 with non-trivial gauge bundles
Energy Technology Data Exchange (ETDEWEB)
Schasny, Martin
2012-10-15
In this thesis we study the heterotic string compactified on K3 with non-trivial gauge bundles. We focus on two backgrounds, the well-known standard embedding and abelian line bundles. Using a Kaluza-Klein reduction, the six-dimensional effective action is computed up to terms of order {alpha}'{sup 2} with special attention on the hypermultiplet sector. We compute the moduli dependent couplings of the matter fields and analyze the geometry of the hyperscalar sigma model. Moreover, we prove the consistency with six-dimensional supergravity and derive the appropriate D-term scalar potential. For the line bundle backgrounds we show that the gauge flux stabilizes some geometrical moduli and renders some abelian vector multiplets massive.

The effects of centrally acting muscle relaxants on the flexor reflex mediated by group II afferent fibers (group II flexor reflex) in anesthetized intact rats and on the intrathecal noradrenaline-HCl-induced facilitation of the group II flexor reflex in anesthetized spinal rats were investigated. In anesthetized intact rats, mephenesin, tolperisone-HCl, chlorpromazine-HCl and baclofen inhibited the group II flexor reflex dose-dependently, whereas the inhibitory effect of tizanidine-HCl was bell-shaped. The effect of diazepam tended to be saturated. In anesthetized spinal rats, mephenesin, tolperisone-HCl, chlorpromazine-HCl, diazepam and baclofen also depressed the group II flexor reflex, but tizanidine-HCl slightly increased it. The intrathecal noradrenaline-HCl-induced facilitation of the group II flexor reflex was not affected by mephenesin or diazepam, but was inhibited by tizanidine-HCl, tolperisone-HCl, chlorpromazine-HCl and baclofen. These results suggest that compounds with centrally acting muscle relaxant activity depress the group II flexor reflex in different manners, and the inhibition of descending noradrenergic tonic facilitation within the spinal cord participates in the depressant action of the group II flexor reflex produced by tolperisone-HCl, tizanidine-HCl, chlorpromazine-HCl and baclofen.

Full Text Available BACKGROUND: There is considerable interest in the potential of private sector subsidies to increase availability and affordability of artemisinin-based combination therapies (ACTs for malaria treatment. A cluster randomized trial of such subsidies was conducted in 3 districts in Kenya, comprising provision of subsidized packs of paediatric ACT to retail outlets, training of retail staff, and community awareness activities. The results demonstrated a substantial increase in ACT availability and coverage, though patient counselling and adherence were suboptimal. We conducted a qualitative study in order to understand why these successes and limitations occurred. METHODOLOGY/PRINCIPAL FINDINGS: Eighteen focus group discussions were conducted, 9 with retailers and 9 with caregivers, to document experiences with the intervention. Respondents were positive about intervention components, praising the focused retailer training, affordable pricing, strong promotional activities, dispensing job aids, and consumer friendly packaging, which are likely to have contributed to the positive access and coverage outcomes observed. However, many retailers still did not stock ACT, due to insufficient supplies, lack of capital and staff turnover. Advice to caregivers was poor due to insufficient time, and poor recall of instructions. Adherence by caregivers to dosing guidelines was sub-optimal, because of a wish to save tablets for other episodes, doses being required at night, stopping treatment when the child felt better, and the number and bitter taste of the tablets. Caregivers used a number of strategies to obtain paediatric ACT for older age groups. CONCLUSIONS/SIGNIFICANCE: This study has highlighted that important components of a successful ACT subsidy intervention are regular retailer training, affordable pricing, a reliable supply chain and community mobilization emphasizing patient adherence and when to seek further care.

Let C'=CⅨM be the trivial extension of a κ-linear category C by a C-bimodule M. It is proved that the left module category C'-Mod is equivalent to the right trivial extension category (C-Mod)[X(M0c-), which generalizes the classical theory on module category of trivial extensions of algebras. When,applying the above result to the ^-linear triangular matrix category,it is easy to describe the structure of its module category%设C是k-线性范畴,M是C-C双模,定义k-线性平凡扩张范畴C′=C(∝)M,首先证明其为平凡扩张代数的自然推广,其次证明左C′-模范畴等价于左C-模范畴关于张量函子M(O)c-的右平凡扩张范畴(C-Mod)(×)(M(O)c—),推广了经典的平凡扩张代数的模范畴理论.并将此结论应用到k-线性三角矩阵范畴,重新刻画其模范畴的结构.

We consider a system of dynamically-modulated photonic resonator lattice undergoing photonic transition, and show that in the ultra-strong coupling regime such a lattice can exhibit non-trivial topological properties, including topologically non-trivial band gaps, and the associated topologically-robust one-way edge states. Compared with the same system operating in the regime where the rotating wave approximation is valid, operating the system in the ultra-strong coupling regime results in one-way edge modes that has a larger bandwidth, and is less susceptible to loss. Also, in the ultra-strong coupling regime, the system undergoes a topological insulator-to-metal phase transition as one varies the modulation strength. This phase transition has no counter part in systems satisfying the rotating wave approximation, and its nature is directly related to the non-trivial topology of the quasi-energy space.

Introduction Functional somatic syndromes (FSS) are common in adolescents, characterised by severe disability and reduced quality of life. Behavioural treatments such as acceptance and commitment therapy (ACT) has shown promising results in children and adolescents with FSS, but has focused on specific syndromes such as functional pain. The current study will compare the efficacy of group-based ACT with that of enhanced usual care (EUC) in adolescents with a range of FSS operationalised by the unifying construct of multiorgan bodily distress syndrome (BDS). Methods and analysis A total of 120 adolescents aged 15–19 and diagnosed with multiorgan BDS, of at least 12 months duration, will be assessed and randomised to either: (1) EUC: a manualised consultation with a child and adolescent psychiatrist and individualised treatment plan or (2) manualised ACT-based group therapy plus EUC. The ACT programme consists of 9 modules (ie, 27 hours) and 1 follow-up meeting (3 hours). The primary outcome is physical health, assessed by an Short Form Health Survey (SF-36) aggregate score 12 months after randomisation. Secondary outcomes include self-reported symptom severity, symptom interference, depression and anxiety, illness worry, perceived stress and global improvement; as well as objective physical activity and bodily stress response measured by heart rate variability, hair cortisol and inflammatory biomarkers. Process measures are illness perception, illness-related behaviour and psychological flexibility. Ethics and dissemination The study is conducted in accordance with Helsinki Declaration II. Approval has been obtained from the Science Ethics Committee of the Central Denmark Region and the Danish Data Protection. The results will be sought to be published according to the CONSORT statement in peer-reviewed journals.

Identity fusion theory suggests that merging groups into one's personal identity should result in heightened levels of group agency. Research on the self-expansion model complementarily indicates that including others into the self is linked to a greater feeling of self-efficacy. Across three correlational studies, we examined whether personal and group identity fusion is associated with stronger feelings of personal agency, and we propose that relatively stable feelings of clarity of self-concept would mediate this association. Individuals strongly fused with a country (Studies 1-3) and family (Study 2) exhibited greater feelings of agency and goal-adherence, and self-concept clarity emerged as a significant mediator of this association when controlling for group identification measures.
Resonant Transparency and Non-Trivial Non-Radiating Excitations in Toroidal Metamaterials
Fedotov, V. A.; Rogacheva, A. V.; Savinov, V.; Tsai, D. P.; Zheludev, N. I.

Engaging strongly resonant interactions allows dramatic enhancement of functionalities of many electromagnetic devices. However, resonances can be dampened by Joule and radiation losses. While in many cases Joule losses may be minimized by the choice of constituting materials, controlling radiation losses is often a bigger problem. Recent solutions include the use of coupled radiant and sub-radiant modes yielding narrow asymmetric Fano resonances in a wide range of systems, from defect states in photonic crystals and optical waveguides with mesoscopic ring resonators to nanoscale plasmonic and metamaterial systems exhibiting interference effects akin to electromagnetically-induced transparency. Here we demonstrate theoretically and confirm experimentally a new mechanism of resonant electromagnetic transparency, which yields very narrow isolated symmetric Lorentzian transmission lines in toroidal metamaterials. It exploits the long sought non-trivial non-radiating charge-current excitation based on interfering electric and toroidal dipoles that was first proposed by Afanasiev and Stepanovsky in [J. Phys. A Math. Gen. 28, 4565 (1995)]. PMID:24132231
Applications Of Topological Field Theory To String Propagation On Non-trivial Backgrounds
Melnikov, I V
2005-01-01
We study several aspects of the classical (gs → 0) limit of string theory. The first of these examines localized tachyon condensation in type II string theory on spacetime non- supersymmetric orbifolds C3/ZN a,b,c . By applying topological field theory methods to the N = (2,2) supersymmetric world-sheet theory, we find that the IR limit of the RG flow associated with tachyon condensation has a non- trivial chiral ring associated to non-geometric discrete vacua. The second part is devoted to studying D-branes in Calabi-Yau manifolds. We present a general method, based on simple notions of classical field theory, for treating bulk symmetries in a field theory on a space with a boundary. We apply this method to the N = (2,2) bulk supersymmetric non- linear sigma model and identify boundary conditions that preserve N = 2 world- sheet supersymmetry. This allows us to classify the possible BPS branes in Calabi-Yau three-folds in the large radius limit. Finally, in the third part we use topologi...
New and trivial C P symmetry for extended A4 flavor
Nishi, C. C.
2016-05-01
The combination of νμ-ντ exchange together with C P conjugation in the neutrino sector (known as CPμ τ symmetry or μ τ reflection) is known to predict the viable pattern θ23=4 5 ° , a maximal Dirac C P phase, and trivial Majorana phases. We implement such a C P symmetry as a new C P symmetry in theories with A4 flavor. The implementation in a complete renormalizable model leads to a new form for the neutrino mass matrix that leads to further predictions: a normal hierarchical spectrum with a lightest mass and mβ β (0 ν 2 β ) of only few meV, and either ν1 or ν2 has opposite C P parity. An approximate Lμ-Lτ symmetry arises naturally and controls the flavor structure of the model. The light neutrino masses are generated by the extended seesaw mechanism with six right-handed neutrinos (RHNs). The requirement of negligible one-loop corrections to light neutrino masses, the validity of the extended seesaw approximation, and not too long-lived beyond-the-Standard-Model states to comply with big bang nucleosynthesis essentially restricts the parameters of the model to a small region: three relatively light right-handed neutrinos at the GeV scale, heavier neutrinos at the electroweak scale, and Yukawa couplings smaller than the electron Yukawa. Such small Yukawa couplings render these RHNs unobservable in terrestrial experiments.
Gauged Nambu-Jona Lasinio Studies of the Triviality of Quantum Electrodynamics
Kim, S; Lombardo, M P; Kogut, John B.; Lombardo, Maria-Paola
2002-01-01
By adding a small, irrelevant four fermi interaction to the action of noncompact lattice Quantum Electrodynamics (QED), the theory can be simulated with massless quarks in a vacuum free of lattice monopoles. The lattice theory possesses a second order chiral phase transition which we show is logarithmically trivial, with the same systematics as the Nambu-Jona Lasinio model. The irrelevance of the four fermi coupling is established numerically. The widths of the scaling windows are examined in both the coupling constant and bare fermion mass directions in parameter space. For vanishing fermion mass we find a broad scaling window in coupling. By adding a small bare fermion mass to the action we find that the width of the scaling window in the fermion mass direction is very narrow. Only when a subdominant scaling term is added to the leading term of the equation of state are adequate fits to the data possible. The failure of past studies of lattice QED to produce equation of state fits with adequate confidence l...
Topologically trivial and nontrivial edge bands in graphene induced by irradiation

2016-08-01
We proposed a minimal model to describe the Floquet band structure of two-dimensional materials with light-induced resonant inter-band transition. We applied it to graphene to study the band features caused by the light irradiation. Linearly polarized light induces pseudo gaps (gaps are functions of wavevector), and circularly polarized light causes real gaps on the quasi-energy spectrum. If the polarization of light is linear and along the longitudinal direction of zigzag ribbons, flat edge bands appear in the pseudo gaps, and if it is in the lateral direction of armchair ribbons, curved edge bands can be found. For the circularly polarized cases, edge bands arise and intersect in the gaps of both types of ribbons. The edge bands induced by the circularly polarized light are helical and those by linearly polarized light are topologically trivial ones. The Chern number of the Floquet band, which reflects the number of pairs of helical edge bands in graphene ribbons, can be reduced into the winding number at resonance.

Let G be a finitely generated infinite pro-p group acting on a pro-p tree such that the restriction of the action to some open subgroup is free. Then we prove that G splits as a pro-p amalgamated product or as a pro-p HNN-extension over an edge stabilizer. Using this result we prove under certain conditions that free pro-p products with procyclic amalgamation inherit from its free factors the property of each 2-generated subgroup being free pro-p. This generalizes known pro-p results, as well as some pro-p analogs of classical results in abstract combinatorial group theory.

Energy landscape of the finite-size mean-field 2-spin spherical model and topology trivialization
Mehta, Dhagash; Hauenstein, Jonathan D.; Niemerg, Matthew; Simm, Nicholas J.; Stariolo, Daniel A.
2015-02-01
Motivated by the recently observed phenomenon of topology trivialization of potential energy landscapes (PELs) for several statistical mechanics models, we perform a numerical study of the finite-size 2-spin spherical model using both numerical polynomial homotopy continuation and a reformulation via non-Hermitian matrices. The continuation approach computes all of the complex stationary points of this model while the matrix approach computes the real stationary points. Using these methods, we compute the average number of stationary points while changing the topology of the PEL as well as the variance. Histograms of these stationary points are presented along with an analysis regarding the complex stationary points. This work connects topology trivialization to two different branches of mathematics: algebraic geometry and catastrophe theory, which is fertile ground for further interdisciplinary research.
Modulated amplitude waves with non-trivial phase in quasi-1D inhomogeneous Bose–Einstein condensates

Torres, Pedro J., E-mail: ptorres@ugr.es

We consider a 1D nonlinear Schrödinger equation (NLSE) which describes the mean field dynamics of an elongated Bose–Einstein condensate and prove the existence of modulated amplitude waves with non-trivial phase and minimal spatial period tending to infinite. The proof combines the theory of local continuation of non-degenerate periodic solutions with a property of the Ermakov–Pinney equation. - Highlights: • A rigorous proof of the existence of rotating MAWs in an inhomogeneous BEC. • No condition on the sign or the magnitude of the trap or the scattering length. • Non-trivial phase leads to a singular ODE for the amplitude. • The proof combines a local continuation theorem and properties of rotation numbers.
General formulae for the su{sub q}(2) 6-j symbols simply obtained thanks to trivial q-identities

The analytical formulae for the su{sub q}(2) 6-j symbols are easily obtained, without the use of any su{sub q}(2)3-j symbol formula. With respect to the checking up on two compatible sets of trivial identities, already successful in the su(2) case , the process becomes still simpler because each set reduces into a single q-numbers identity.

Full Text Available In portions of South Asia, vectors and patients co-infected with dengue (DENV and chikungunya (CHIKV are on the rise, with the potential for this occurrence in other regions of the world, for example the United States. Therefore, we engineered an antiviral approach that suppresses the replication of both arboviruses in mosquito cells using a single antiviral group I intron. We devised unique configurations of internal, external, and guide sequences that permit homologous recognition and splicing with conserved target sequences in the genomes of both viruses using a single trans-splicing Group I intron, and examined their effectiveness to suppress infections of DENV and CHIKV in mosquito cells when coupled with a proapoptotic 3' exon, ΔN Bax. RT-PCR demonstrated the utility of these introns in trans-splicing the ΔN Bax sequence downstream of either the DENV or CHIKV target site in transformed Aedes albopictus C6/36 cells, independent of the order in which the virus specific targeting sequences were inserted into the construct. This trans-splicing reaction forms DENV or CHIKV ΔN Bax RNA fusions that led to apoptotic cell death as evidenced by annexin V staining, caspase, and DNA fragmentation assays. TCID50-IFA analyses demonstrate effective suppression of DENV and CHIKV infections by our anti-arbovirus group I intron approach. This represents the first report of a dual-acting Group I intron, and demonstrates that we can target DENV and CHIKV RNAs in a sequence specific manner with a single, uniquely configured CHIKV/DENV dual targeting group I intron, leading to replication suppression of both arboviruses, and thus providing a promising single antiviral for the transgenic suppression of multiple arboviruses.
Non-trivial reputation effects on social decision making in virtual environment
Duradoni, Mirko; Guazzini, Andrea
2016-01-01
Reputation systems are currently used, often with success, to ensure the functioning of online services as well as of e-commerce sites. Despite the relationship between reputation and material cooperative behaviours is quite supported, less obvious appears the relationship with informative behaviours, which are crucial for the transmission of reputational information and therefore for the maintenance of cooperation among individuals. The purpose of this study was to verify how reputation affects cooperation dynamics in virtual environment, within a social dilemma situation (i.e., where there are incentives to act selfishly). The results confirm that reputation can activate prosocial conducts, however it highlights also the limitations and distortions that reputation can create.
Group actions on C*-algebras, 3-cocycles and quantum field theory

We study group extensions Δ→Γ→Ω, where Γ acts on a C*-algebra A. Given a twisted covariant representation π, V of the pair A, Δ we construct 3-cocycles on Ω with values in the centre of the group generated by V(Δ). These 3-cocycles are obstructions to the existence of an extension of Ω by V(Δ) which acts on A compatibly with Γ. The main theorems of the paper introduce a subsidiary invariant Λ which classifies actions of Γ on V(Δ) and in terms of which a necessary and sufficient condition for the the cohomology class of the 3-cocycle to be non-trivial may be formulated. Examples are provided which show how non-trivial 3-cocycles may be realised. The framework we choose to exhibit these essentially mathematical results is influenced by anomalous gauge field theories. We show how to interpret our results in that setting in two ways, one motivated by an algebraic approach to constrained dynamics and the other by the descent equation approach to constructing cocycles on gauge groups. In order to make comparisons with the usual approach to cohomology in gauge theory we conclude with a Lie algebra version of the invariant Λ and the 3-cocycle.

Inhaled short-acting beta-agonist (SABA) medication is commonly used in asthma patients to rapidly reverse airway obstruction and improve acute symptoms. We performed a genome-wide association study of SABA medication response using gene-based association tests. A linear mixed model approach was first used for single-nucleotide polymorphism associations, and the results were later combined using GATES to generate gene-based associations. Our results identified SPATA13-AS1 as being significantly associated with SABA bronchodilator response in 328 healthy African Americans. In replication, this gene was associated with SABA response among the two separate groups of African Americans with asthma (n=1073, P=0.011 and n=1968, P=0.014), 149 healthy African Americans (P=0.003) and 556 European Americans with asthma (P=0.041). SPATA13-AS1 was also associated with longitudinal SABA medication usage in the two separate groups of African Americans with asthma (n=658, P=0.047 and n=1968, P=0.025). Future studies are needed to delineate the precise mechanism by which SPATA13-AS1 may influence SABA response.
Understanding communication among deaf students who sign and speak: a trivial pursuit?
Marschark, Marc; Convertino, Carol M; Macias, Gayle; Monikowski, Christine M; Sapere, Patricia; Seewagen, Rosemarie
2007-01-01
Classroom communication between deaf students was modeled using a question-and-answer game. Participants consisted of student pairs that relied on spoken language, pairs that relied on American Sign Language (ASL), and mixed pairs in which one student used spoken language and one signed. Although the task encouraged students to request clarification of messages they did not understand, such requests were rare, and did not vary across groups. Face-to-face communication was relatively poor in all groups. Students in the ASL group understood questions more readily than students who relied on oral communication. Although comprehension was low for all groups, those using oral communication provided more correct free responses, although the numbers were low; no significant differences existed for multiple-choice responses. Results are discussed in terms of the possibility that many deaf students have developed lower criteria for comprehension, and related challenges for classroom communication access.
Unitary Representations of Gauge Groups
Huerfano, Ruth Stella
I generalize to the case of gauge groups over non-trivial principal bundles representations that I. M. Gelfand, M. I. Graev and A. M. Versik constructed for current groups. The gauge group of the principal G-bundle P over M, (G a Lie group with an euclidean structure, M a compact, connected and oriented manifold), as the smooth sections of the associated group bundle is presented and studied in chapter I. Chapter II describes the symmetric algebra associated to a Hilbert space, its Hilbert structure, a convenient exponential and a total set that later play a key role in the construction of the representation. Chapter III is concerned with the calculus needed to make the space of Lie algebra valued 1-forms a Gaussian L^2-space. This is accomplished by studying general projective systems of finitely measurable spaces and the corresponding systems of sigma -additive measures, all of these leading to the description of a promeasure, a concept modeled after Bourbaki and classical measure theory. In the case of a locally convex vector space E, the corresponding Fourier transform, family of characters and the existence of a promeasure for every quadratic form on E^' are established, so the Gaussian L^2-space associated to a real Hilbert space is constructed. Chapter III finishes by exhibiting the explicit Hilbert space isomorphism between the Gaussian L ^2-space associated to a real Hilbert space and the complexification of its symmetric algebra. In chapter IV taking as a Hilbert space H the L^2-space of the Lie algebra valued 1-forms on P, the gauge group acts on the motion group of H defining in an straight forward fashion the representation desired.

Path integrals don't really exist, but it is very useful to dream that they do exist, and figure out the consequences. Apart from describing much of the physical world as we now know it, these dreams also lead to some highly non-trivial mathematical theorems and theories. We argue that even though non-trivial flat connections on S^3 don't really exist, it is beneficial to dream that one exists (and, in fact, that it comes from the non-existent Chern-Simons path integral). Dreaming the right way, we are led to a rigorous construction of a universal finite-type invariant of rational homology spheres. We show that this invariant recovers the Rozansky invariants and that it is essentially equal to the LMO (Le-Murakami-Ohtsuki) invariant. This is part I of a 4-part series, containing the introductions and answers to some frequently asked questions. Theorems are stated but not proved in this part, and it can be viewed as a "research announcement". Part II of this series will be titled "Invariance and Universality",...

Many names of plant secondary compounds that have been isolated and identified in the course of phytochemical investigations are based either on the vernacular or Latin names of the source plants, are constructed according to rules of chemical nomenclature, or consist of in-between forms. Trivial names, based on the specific epithets of biological organisms, occasionally create confusion because such epithets are used in numerous combinations and, therefore, could potentially be used when naming chemical entities from radically different sources. Such an example of ambiguous naming is represented with the case of corymbosin, a name that was assigned to two chemically distinct compounds that were isolated and reported simultaneously in 1967 from two different spermatophyte taxa: a terpene glucoside from Turbina corymbosa and a flavone from Webera corymbosa. The flavone is more widespread and has been reported so far from 15 taxa, whereas the glucoside has thus far only been isolated from the original source species. Furthermore, glycosides named corymbosins K1-K4 were isolated in 2006 from Knoxia corymbosa. This article emphasizes the need to adhere to strict principles when naming secondary constituents and suggests that a practice should be applied that is similar to the application of the priority rules used in botanical nomenclature for homonyms. The use of the trivial name, corymbosin, should be applied only to the more widespread tricetin-7,3',4',5'-tetramethyl ether by rules of conservation.

Full Text Available Rabbit Hemorrhagic disease virus (RHDV, a calicivirus of the Lagovirus genus, and responsible for rabbit hemorrhagic disease (RHD, kills rabbits between 48 to 72 hours post infection with mortality rates as high as 50-90%. Caliciviruses, including noroviruses and RHDV, have been shown to bind histo-blood group antigens (HBGA and human non-secretor individuals lacking ABH antigens in epithelia have been found to be resistant to norovirus infection. RHDV virus-like particles have previously been shown to bind the H type 2 and A antigens. In this study we present a comprehensive assessment of the strain-specific binding patterns of different RHDV isolates to HBGAs. We characterized the HBGA expression in the duodenum of wild and domestic rabbits by mass spectrometry and relative quantification of A, B and H type 2 expression. A detailed binding analysis of a range of RHDV strains, to synthetic sugars and human red blood cells, as well as to rabbit duodenum, a likely gastrointestinal site for viral entrance was performed. Enzymatic cleavage of HBGA epitopes confirmed binding specificity. Binding was observed to blood group B, A and H type 2 epitopes in a strain-dependent manner with slight differences in specificity for A, B or H epitopes allowing RHDV strains to preferentially recognize different subgroups of animals. Strains related to the earliest described RHDV outbreak were not able to bind A, whereas all other genotypes have acquired A binding. In an experimental infection study, rabbits lacking the correct HBGA ligands were resistant to lethal RHDV infection at low challenge doses. Similarly, survivors of outbreaks in wild populations showed increased frequency of weak binding phenotypes, indicating selection for host resistance depending on the strain circulating in the population. HBGAs thus act as attachment factors facilitating infection, while their polymorphism of expression could contribute to generate genetic resistance to RHDV at the
Triviality of hierarchical O(N) spin model in four dimensions with large N
Watanabe, H
2003-01-01
The renormalization group transformation for the hierarchical O(N) spin model in four dimensions is studied by means of characteristic functions of single-site measures, and convergence of the critical trajectory to the Gaussian fixed point is shown for a sufficiently large N. In the strong coupling regime, the trajectory is controlled by the help of the exactly solved O(\\infty) trajectory, while, in the weak coupling regime, convergence to the Gaussian fixed point is shown by power decay of the effective coupling constant.
FAST TRACK COMMUNICATION: A trivial observation on time reversal in random matrix theory
Kaplan, L.; Leyvraz, F.; Pineda, C.; Seligman, T. H.
2007-12-01
It is commonly thought that a state-dependent quantity, after being averaged over a classical ensemble of random Hamiltonians, will always become independent of the state. We point out that this is in general incorrect: if the ensemble of Hamiltonians is time-reversal invariant, and the quantity involves the state in higher than bilinear order, then we show that the quantity is only a constant over the orbits of the invariance group on the Hilbert space. Examples include fidelity and decoherence in appropriate models.
When is Menzerath-Altmann law mathematically trivial? A new approach.
Ferrer-i-Cancho, Ramon; Hernández-Fernández, Antoni; Baixeries, Jaume; Dębowski, Łukasz; Mačutek, Ján
2014-12-01
Menzerath's law, the tendency of Z (the mean size of the parts) to decrease as X (the number of parts) increases, is found in language, music and genomes. Recently, it has been argued that the presence of the law in genomes is an inevitable consequence of the fact that Z=Y/X, which would imply that Z scales with X as Z ∼ 1/X. That scaling is a very particular case of Menzerath-Altmann law that has been rejected by means of a correlation test between X and Y in genomes, being X the number of chromosomes of a species, Y its genome size in bases and Z the mean chromosome size. Here we review the statistical foundations of that test and consider three non-parametric tests based upon different correlation metrics and one parametric test to evaluate if Z ∼ 1/X in genomes. The most powerful test is a new non-parametric one based upon the correlation ratio, which is able to reject Z ∼ 1/X in nine out of 11 taxonomic groups and detect a borderline group. Rather than a fact, Z ∼ 1/X is a baseline that real genomes do not meet. The view of Menzerath-Altmann law as inevitable is seriously flawed.
Hecke Transformations of Conformal Blocks in WZW Theory. I. KZB Equations for Non-Trivial Bundles

Full Text Available We describe new families of the Knizhnik-Zamolodchikov-Bernard (KZB equations related to the WZW-theory corresponding to the adjoint $G$-bundles of different topological types over complex curves $Sigma_{g,n}$ of genus $g$ with $n$ marked points. The bundles are defined by their characteristic classes - elements of $H^2(Sigma_{g,n},mathcal{Z}(G$, where $mathcal{Z}(G$ is a center of the simple complex Lie group $G$. The KZB equations are the orizontality condition for the projectively flat connection (the KZB connectiondefined on the bundle of conformal blocks over the moduli space of curves. The space of conformal blocks has been known to be decomposedinto a few sectors corresponding to the characteristic classes of the underlying bundles. The KZB connection preserves these sectors.In this paper we construct the connection explicitly for elliptic curves with marked points and prove its flatness.
Exploring the cognitive components of solving non-trivial physics problems
Korsunsky, Boris Mikhaylovich
This study explores the cognitive mechanisms of problem solving in physics and the students' problem-solving strategies. Based on the review of prior research and on the author's own experience, a theory of problem-solving skills is proposed. This theory suggests the existence of a meaningful dichotomy between the students' rigid knowledge and their bisociation skills. The goals of the study are to test the proposed theory and to gain further insight into the nature of students' difficulties and the strategies that help successful solvers to overcome those difficulties. To conduct the study, a large group of AP Physics C students was given several physics tasks to solve. The participants' interactions with the tasks were observed and recorded in several different ways. The data collected are analyzed in conjunction with the background information provided by the students. Correlation statistics and linear regression models are used to determine the factors relevant to individuals' success in problem solving. The written comments and the protocols of student interviews are analyzed qualitatively, using the narrative summary and the cluster methods. The results support the idea of rigid knowledge and bisociation being two distinct sets of skills essential to problem solving; the notion of bisociation as the main factor limiting one's problem-solving success is also supported. In addition, specific behaviors associated with both successful and unsuccessful problem-solving processes were identified and analyzed. Based on the findings of the study, new approaches to teacher training, curriculum development, educational research and classroom practice are proposed.

In this paper, the automorphism group of a generalized extraspecial p-group G is determined, where p is a prime number. Assume that |G| = p 2n+m and |ζG| = p m , where n 1 and m 2. (1) When p is odd, let Aut G G = {α∈ AutG | α acts trivially on G }. Then Aut G G⊿AutG and AutG/Aut G G≌Z p-1 . Furthermore, (i) If G is of exponent p m , then Aut G G/InnG≌Sp(2n, p) × Z p m-1 . (ii) If G is of exponent p m+1 , then Aut G G/InnG≌ (K Sp(2n-2, p))×Z p m-1 , where K is an extraspecial p-group of order p 2n-1 . In particular, Aut G G/InnG≌ Z p × Z p m-1 when n = 1. (2) When p = 2, then, (i) If G is of exponent 2 m , then AutG≌ Sp(2n, 2) × Z 2 × Z 2 m-2 . In particular, when n = 1, |AutG| = 3 · 2 m+2 . None of the Sylow subgroups of AutG is normal, and each of the Sylow 2-subgroups of AutG is isomorphic to H K, where H = Z 2 × Z 2 × Z 2 × Z 2 m-2 , K = Z 2 . (ii) If G is of exponent 2 m+1 , then AutG≌ (I Sp(2n-2, 2)) × Z 2 × Z 2 m-2 , where I is an elementary abelian 2-group of order 2 2n-1 . In particular, when n = 1, |AutG| = 2 m+2 and AutG≌ H K, where H = Z 2 × Z 2 × Z 2 m-1 , K = Z 2 .

Acceptance and commitment therapy (ACT) is a developing approach for chronic pain. The current study was designed to pilot test a brief, widely inclusive, local access format of ACT in a UK primary care setting. Seventy-three participants (68.5% women) were randomized to either ACT or treatment as usual (TAU). Many of the participants were aged 65 years or older (27.6%), were diagnosed with fibromyalgia (30.2%) and depression (40.3%), and had longstanding pain (median = 10 years). Standard clinical outcome measures included disability, depression, physical functioning, emotional functioning, and rated improvement. Process measures included pain-related and general psychological acceptance. The recruitment target was met within 6 months, and 72.9% of those allocated to ACT completed treatment. Immediately post treatment, relative to TAU, participants in ACT demonstrated lower depression and higher ratings of overall improvement. At a 3-month follow-up, again relative to TAU, those in ACT demonstrated lower disability, less depression, and significantly higher pain acceptance; d = .58, .59, and .64, respectively. Analyses based on intention-to-treat and on treatment "completers," perhaps predictably, revealed more sobering and more encouraging results, respectively. A larger trial of ACT delivered in primary care, in the format employed here, appears feasible with some recommended adjustments in the methods used here (Trial registration: ISRCTN49827391). This article presents a pilot randomized controlled trial of ACT for chronic pain in a primary care setting in the United Kingdom. Both positive clinical outcomes and ways to improve future trials are reported. Copyright © 2013 American Pain Society. All rights reserved.
On Segal-Bargmann analysis for finite Coxeter groups and its heat kernel
Sontz, Stephen Bruce
2009-01-01
We prove identities involving the integral kernels of three versions of the Segal-Bargmann transform associated to a Coxeter group (defined by a finite root system) acting on a finite dimensional, real Euclidean space (one of these kernels having been introduced around the same time by Ben Said and Orsted and independently by Soltani) and the Dunkl heat kernel of the Dunkl Laplacian associated with the same Coxeter group, due to Rosler. All but one of our relations are originally due to Hall in the context of standard Segal-Bargmann analysis on Euclidean space. Hall's results (trivial Dunkl structure and arbitrary finite dimension) as well as our own results in mu-deformed quantum mechanics (non-trivial Dunkl structure, dimension one) are particular cases of the results proved here. So we can understand all of these versions of the Segal-Bargmann transform associated to a Coxeter group as Hall type transforms. In particular, we define an analogue of Hall's "Version C" generalized Segal-Bargmann transform whic...

The quantum spin Hall insulators predicted ten years ago and now experimentally observed are instrumental for a break- through in nanoelectronics due to non-dissipative spin-polarized electron transport through their edges. For this transport to persist at normal conditions, the insulators should possess a sufficiently large band gap in a stable topological phase. Here, we theoretically show that quantum spin Hall insulators can be realized in ultra-thin films constructed from a trivial band insulator with strong spin-orbit coupling. The thinnest film with an inverted gap large enough for practical applications is a centrosymmetric sextuple layer built out of two inversely stacked non-centrosymmetric BiTeI trilayers. This nontrivial sextuple layer turns out to be the structure element of an artificially designed strong three-dimensional topological insulator Bi2Te2I2. We reveal general principles of how a topological insulator can be composed from the structure elements of the BiTeX family (X = I, Br, Cl), which opens new perspectives towards engineering of topological phases.

Bieberbach groups with symmetric point group are polycyclic. The properties of the groups can be explored by computing their homological functors. In this paper, some homological functors of a Bieberbach group with symmetric point group, such as the Schur multiplier and the G-trivial subgroup of the nonabelian tensor square, are generalized up to finite dimension and are represented in the form of direct product of cyclic groups.
Noether's problem for $p$-groups with an abelian subgroup of index $p$
Michailov, Ivo M
2012-01-01
Let $K$ be a field and $G$ be a finite group. Let $G$ act on the rational function field $K(x(g):g\\in G)$ by $K$ automorphisms defined by $g\\cdot x(h)=x(gh)$ for any $g,h\\in G$. Denote by $K(G)$ the fixed field $K(x(g):g\\in G)^G$. Noether's problem then asks whether $K(G)$ is rational over $K$. In this paper, we give a positive answer to the Noether's problem for all $p$-groups with an abelian subgroup of index $p$ and with a trivial $p$-th lower central subgroup, provided that $K$ contains sufficient roots of unity.
Basic Questions on Artin-Tits groups
Godelle, Eddy
2011-01-01
This paper is a short survey on four basic questions on Artin-Tits groups: the torsion, the center, the word problem, and the cohomology ($K(\\pi,1)$ problem). It is also an opportunity to prove three new results concerning these questions: (1) if all free of infinity Artin-Tits groups are torsion free, then all Artin-Tits groups will be torsion free; (2) If all free of infinity irreducible non-spherical type Artin-Tits groups have a trivial center then all irreducible non-spherical type Artin-Tits groups will have a trivial center; (3) if all free of infinity Artin-Tits groups have solutions to the word problem, then all Artin-Tits groups will have solutions to the word problem. Recall that an Artin-Tits group is free of infinity if its Coxeter graph has no edge labeled by $\\infty$.

Most individuals possess more than one relevant social identity, but these social identities can be more or less incompatible. Research has demonstrated that incompatibility between an established social identity and a potential new social identity impedes the integration into the new group. We argue that incompatibility is a strong risk factor for disidentification, i.e., a negative self-defining relation to a relevant group. The current research investigates the impact of incompatibilities on disidentification in the acculturation context. We propose that incompatibility between one’s cultural identities increases the disidentification with the receiving society. It has, however, been shown that the motivation to be a group member serves as a buffer against negative integration experiences. Moreover, research from the intercultural domain has shown that intrinsic and extrinsic motivation has specific effects for members of cultures that differ in self-construal. In a European sample of High school exchange students (Study 1, N = 378), it was found that incompatibility was positively related to disidentification, but only for less (but not more) intrinsically motivated newcomers. In an Asian sample of international university students (Study 2, N = 74), it was found that incompatibility was also positively related to disidentification, but only for less (but not more) extrinsically motivated newcomers. Thus, the findings demonstrate that the effect of incompatibility between social identities on disidentification can be buffered by motivation. The results suggest that, depending on cultural self-construal, individuals have different resources to buffer the negative effect of incompatibility on the social identity. PMID:28326055

The Biopharmaceutics Classification System (BCS) allows compounds to be classified based on their in vitro solubility and intestinal permeability. The BCS has found widespread use in the pharmaceutical community to be an enabling guide for the rational selection of compounds, formulation for clinical advancement, and generic biowaivers. The Pediatric Biopharmaceutics Classification System (PBCS) Working Group was convened to consider the possibility of developing an analogous pediatric-based classification system. Because there are distinct developmental differences that can alter intestinal contents, volumes, permeability, and potentially biorelevant solubilities at different ages, the PBCS Working Group focused on identifying age-specific issues that need to be considered in establishing a flexible, yet rigorous PBCS. We summarized the findings of the PBCS Working Group and provided insights into considerations required for the development of a PBCS. Through several meetings conducted both at The Eunice Kennedy Shriver National Institute of Child Health, Human Development-US Pediatric Formulation Initiative Workshop (November 2011) and via teleconferences, the PBCS Working Group considered several high-level questions that were raised to frame the classification system. In addition, the PBCS Working Group identified a number of knowledge gaps that need to be addressed to develop a rigorous PBCS. It was determined that for a PBCS to be truly meaningful, it needs to be broken down into several different age groups that account for developmental changes in intestinal permeability, luminal contents, and gastrointestinal (GI) transit. Several critical knowledge gaps were identified, including (1) a lack of fully understanding the ontogeny of drug metabolizing enzymes and transporters along the GI tract, in the liver, and in the kidney; (2) an incomplete understanding of age-based changes in the GI, liver, and kidney physiology; (3) a clear need to better understand
On primordial groups for the Green ring
Raggi-Cardenas, Alberto; Romero, Nadia
2009-01-01
Consider the Mackey functor assigning to each finite group G the Green ring of finitely generated kG-modules, where k is a field of characteristic p>0. Thevenaz foresaw in 1988 that the class of primordial groups for this functor is the family of k-Dress groups. In this paper we prove that this is true for the subfunctor defined by the Green ring of finitely generated kG-modules of trivial source.

The paper is devoted to study the structure of Hawaiian groups of some topological spaces. We present some behaviors of Hawaiian groups with respect to product spaces, weak join spaces, cone spaces, covering spaces and locally trivial bundles. In particular, we determine the structure of the $n$-dimensional Hawaiian group of the $m$-dimensional Hawaiian earring space, for all $1\\leq m\\leq n$.

Workers from the law enforcement and healthcare sectors tend to normalize or mute their victimization from workplace violence (WPV). This study aims to assess the impact of the trivialization of WPV on psychological consequences for workers who have been affected by a WPV incident. The second aim is to assess the moderating effect of sex on the trivialization of WPV. The third and overarching aim is to assess the moderating effect of professional identity on the relations between individual and organizational factors and psychological consequences following a WPV incident. The findings are based on a convenience sample of 377 (204 female and 173 male) workers from the law enforcement and healthcare sectors. Individual factors (sex, age, professional identity, prior victimization, witnessing WPV, injuries, and trivialization of violence) and perceived support factors (colleagues' support and employer's support) were used as predictor variables of psychological consequences in hierarchical linear regression models. Sex was used as a moderator of trivialization while professional identity was used as a moderator of all predictors. When individual and social support factors were controlled for, normalizing violence was negatively associated with psychological consequences while perceiving a taboo associated with complaining about WPV was positively associated for all participants. When these relations were moderated by the sex of the participants and then by their professional identity, normalization was found to decrease psychological consequences only for male healthcare workers. To help employees cope with WPV, organizations should promote strategies adapted to profession and sex differences. For male healthcare workers, normalization as a cognitive coping strategy should be formally recognized. For both professions and sexes, organizational strategies that counter the perceived taboo of complaining about violence should be reinforced.
The equation x^{p}y^{q} = z^{r} and groups that act freely on Λ-trees

Let G be a group that acts freely on a Λ-tree, where Λ is an ordered abelian group, and let x,y,z be elements in G. We show that if xpyq = zr with integers p, q, r ≥ 4, then x, y and z commute. As a result, the one-relator groups with xpyq = zr as relator, are examples of hyperbolic and CAT( − 1) groups which do not act freely on any Λ-tree.

Characteristic Classes and Integrable Systems for Simple Lie Groups
Levin, A; Smirnov, A; Zotov, A
2010-01-01
This paper is a continuation of our previous paper \\cite{LOSZ}. For simple complex Lie groups with non-trivial center, i.e. classical simply-connected groups, $E_6$ and $E_7$ we consider elliptic Modified Calogero-Moser systems corresponding to the Higgs bundles with an arbitrary characteristic class. These systems are generalization of the classical Calogero-Moser (CM) systems related to a simple Lie groups and contain CM systems related to some (unbroken) subalgebras. For all algebras we construct a special basis, corresponding to non-trivial characteristic classes, the explicit forms of Lax operators and Hamiltonians.
An analogue to Dixon's theorem for automaton groups
Godin, Thibault
2017-01-01
International audience; Dixon's famous theorem states that the group generated by two random permutations of a finite set is generically either the whole symmetric group or the alternating group. In the context of random generation of finite groups this means that it is hopeless to wish for a uniform distribution – or even a non-trivial one – by drawing random permutations and looking at the generated group. Mealy automata are a powerful tool to generate groups, including all finite groups an...

We prove that the Griffiths group of 3-cycles homologous to zero modulo algebraic equivalence, on a generic hypersurfaces of dimension 7 and degree 3 is not finitely generated, even when tensored with Q. Using this and a result of Nori, we give examples of varieties for which some Griffiths group is not finitely generated (modulo torsion) but whose corresponding intermediate Jacobian is trivial.

We try to use scale-invariance and the 1/N expansion to construct a non-trivial 4d O(N) scalar field model with controlled UV behavior and naturally light scalar excitations. The principle is to fix interactions at each order in 1/N by requiring the effective action for arbitrary background fields to be scale-invariant. We find a line of non-trivial UV fixed-points in the large-N limit, parameterized by a dimensionless coupling. Nether action nor measure is scale invariant, but the effective action is. Scale invariance makes it natural to set a mass deformation to zero. The model has phases where O(N) invariance is unbroken or spontaneously broken. Masses of the lightest excitations above the unbroken vacuum are found. Slowly varying quantum fluctuations are incorporated at order 1/N. We find the 1/N correction to the potential, beta function of mass and anomalous dimensions of fields that preserve a line of fixed points for constant backgrounds.
On elliptic Calogero-Moser systems for complex crystallographic reflection groups
Etingof, Pavel; Ma, Xiaoguang; Veselov, Alexander
2010-01-01
To every irreducible finite crystallographic reflection group (i.e., an irreducible finite reflection group G acting faithfully on an abelian variety X), we attach a family of classical and quantum integrable systems on X (with meromorphic coefficients). These families are parametrized by G-invariant functions of pairs (T,s), where T is a hypertorus in X (of codimension 1), and s in G is a reflection acting trivially on T. If G is a real reflection group, these families reduce to the known generalizations of elliptic Calogero-Moser systems, but in the non-real case they appear to be new. We give two constructions of the integrals of these systems - an explicit construction as limits of classical Calogero-Moser Hamiltonians of elliptic Dunkl operators as the dynamical parameter goes to 0 (implementing an idea of arXiv:hep-th/9403178), and a geometric construction as global sections of sheaves of elliptic Cherednik algebras for the critical value of the twisting parameter. We also prove algebraic integrability ...

The reaction of the real aerobic activated sludge taken from the Sofia Waste Water Treatment Plant (SWWTP) and treated with the xenobiotics pentachlorphenol (PCP) (0.16 mMol), ortho-nitrophenol (oNP) (0.58 mMol) and with a combination of PCP (0.08 mMol), oNP (0.29 mMol) has been investigated in a model detoxification process. The adaptive changes are studied in the microbial structure level and at the level of changes in the qualitative and quantitative parameters of the macro-organisms in the activated sludge (consuments of 1 and 2 level). The presence of several different taxonomic groups has been shown by other researchers to be essential in the detoxification process. The quantitative changes in these taxonomic and physiological groups of micro-organisms are studied. The number of micro-organisms from Pseudomonas, Acinetobacter and the bacteria from the xenobiotic-catabolizing complex considerably increased with the individual and the combined effect of the xenobiotics oNP, PCP and oNP PCP. At the same time the toxic shock leads to a remarkable reduction of NH[sub 3] releasing, nitrifying bacteria and those from family Enterobacteriaceae. It is ascertained that the number of Ciliata, Flagellata apochromata, Oligochaeta and Rotatoria is strongly decreased in the series of samples treated with xenobiotics. The leading role of micro-organisms in the real detoxification of hazardous pollutants was experimentally confirmed by research.
A remark on the motivic Galois group and the quantum coadjoint action
Grosse, H; Grosse, Harald; Schlesinger, Karl-Georg
2004-01-01
It was suggested by Kontsevich that the Grothendieck-Teichmueller group GT should act on the Duflo isomorphism of su(2) but the corresponding realization of GT turned out to be trivial. We show that a solvable quotient of the motivic Galois group - which is supposed to agree with GT - is closely related to the quantum coadjoint action on U_q(sl_2) for q a root of unity, i.e. in the quantum group case one has a nontrivial realization of a quotient of the motivic Galois group. From a discussion of the algebraic properties of this realization we conclude that in more general cases than U_q(sl_2) it should be related to a quantum version of the motivic Galois group. Finally, we discuss the relation of our construction to quantum field and string theory and explain what we believe to be the "physical reason" behind this relation between the motivic Galois group and the quantum coadjoint action. This might be a starting point for the generalization of our construction to more involved examples.

The spacing intervals of adjacent Riemann zeta zeros(non-trivial) exhibit fractal(irregular) fluctuations generic to dynamical systems in nature such as fluid flows, heart beat patterns, stock market price index, etc., and are associated with unpredictability or chaos. The power spectra of such fractal space-time fluctuations exhibit universal inverse power law form and signify long-range correlations, identified as self-organized criticality . A cell dynamical system model developed by the author for turbulent fluid flows provides a unique quantification for the observed power spectra in terms of the statistical normal distribution, such that the variance represents the statistical probability densities. Such a result that the additive amplitudes of eddies when squared, represent the statistical probabilities is an observed feature of the subatomic dynamics of quantum systems such as an electron or photon. Self-organized criticality is therefore a signature of quantum-like chaos in dynamical systems. The mod...

The formation, structure and electronic properties of SnSe2-Bi2Se3 van der Waals heterostructures were studied. Both heterostructures, SnSe2 on Bi2Se3 and Bi2Se3 on SnSe2, were grown epitaxially with high crystallinity and sharp interfaces. Their electron band structures are of trivial and topological insulators, respectively. The Dirac surface states of Bi2Se3 survive under the SnSe2 overlayer. One triple layer of SnSe2 was found to be an efficient spacer for separating a Bi2Se3 topological-insulator slab into two and creating the corresponding topological surface states.

This paper characterizes the quasilocal fields from the class of Henselian valued fields with totally indivisible value groups, which possess finite separable extensions of nontrivial defect. We show that, for any prime number $q$, a divisible subgroup $T$ in the multiplicative group of complex numbers is realizable as the Brauer group of such a quasilocal field of residual characteristic $q$ unless $q = 2$ and the $2$-component of T$ is trivial.
A quasi-isometric embedding theorem for groups

We also discuss some applications to compression functions of Lipschitz embeddings into uniformly convex Banach spaces, F{\\o}lner functions, and elementary classes of amenable groups.

3-manifold groups are virtually residually p
Aschenbrenner, Matthias
2010-01-01
Given a prime $p$, a group is called residually $p$ if the intersection of its $p$-power index normal subgroups is trivial. A group is called virtually residually $p$ if it has a finite index subgroup which is residually $p$. It is well-known that finitely generated linear groups over fields of characteristic zero are virtually residually $p$ for all but finitely many $p$. In particular, fundamental groups of hyperbolic $3$-manifolds are virtually residually $p$. It is also well-known that fundamental groups of $3$-manifolds are residually finite. In this paper we prove a common generalization of these results: every $3$-manifold group is virtually residually $p$ for all but finitely many~$p$. This gives evidence for the conjecture (Thurston) that fundamental groups of $3$-manifolds are linear groups.

Product-free subsets of profinite groups
Bardestani, Mohammad
2012-01-01
Gowers in his paper on quasirandom groups studies a question of Babai and Sos asking whether there exists a constant $c > 0$ such that every finite group $G$ has a product-free subset of size at least $c|G|$. Answering the question negatively, he proves that for sufficiently large prime $p$, the group $\\mathrm{PSL}_2(\\mathbb{F}_p)$ has no product-free subset of size $cn^{8/9}$, where $n$ is the order of $\\mathrm{PSL}_2(\\mathbb{F}_p)$. We will consider the problem for compact groups and in particular for profinite groups $\\SL_k(\\ZZ_p)$ obtain lower and upper exponential bounds for the supremal measure of the product-free sets. The proof involves establishing a lower bound for the dimension of non-trivial representations of the finite groups $\\SL_k(\\Z{p^n})$.

Full Text Available The article discusses the poem by Afanasy Fet “Whisper, timid breathing…” in the edition of 1856, which became a classic. The poetic dictionary of the poem is more than rather banal. Such lexemes as nightingale, stream, kiss, tears, became more than trivial to the Fet’s time. Moreover, the connection between these lexemes and the theme of love and night landscape is quite predictable in this poem. Meanwhile, the poem was perceived by the contemporaries of its author as the most famous poetic written by Fet — as a kind of “motto” and a sign of his lyrics, This fact is evidenced by numerous references in literary criticism and by parodies. Two features give this text the distinct personality. Firstly, the author updates connotative meanings of lexemes, giving them the character of trope (nightingale — lover, breath — an attribute not only of the heroine, but also of spiritualized nature, dawn refers not only to real dawn in the morning nature, but also to the “flash” in the souls of lovers or metaphorical semantics of “the second row” (in the general context with nightingale, rose, being a metaphor of the dawn, is associated with lthe heroine — compare these images with the nightingale and the rose in Persian poetry, familiar to Fet. The text reveals connotative language capabilities. Soб the two plans of the poem — the world of lovers and the world of nature — discover the similarities and merge with each other. Secondly, the absolutely nontrivial character of the poem is determined by the use of the impersonal sentences: usually fixing the static situation, in Fet’s text they acquire the ability to describe the dynamics, the sequence of actions. Semantics comes into fruitful conflict with the syntax: each part in the complex sentence captures a static picture. But as as whole they represent the movement — from a quiet conversation to an emotional outburst, from night to morning.
Topologically twisted renormalization group flow and its holographic dual
Nakayama, Yu
2016-01-01
Euclidean field theories admit more general deformations than usually discussed in quantum field theories because of mixing between rotational symmetry and internal symmetry (a.k.a topological twist). Such deformations may be relevant, and if the subsequent renormalization group flow leads to a non-trivial fixed point, it generically gives rise to a scale invariant Euclidean field theory without conformal invariance. Motivated by an ansatz studied in cosmological models some time ago, we develop a holographic dual description of such renormalization group flows in the context of AdS/CFT. We argue that the non-trivial fixed points require fine-tuning of the bulk theory in general, but remarkably we find that the $O(3)$ Yang-Mills theory coupled with the four-dimensional Einstein gravity in the minimal manner supports such a background with the Euclidean AdS metric.
Quasi hope algebras, group cohomology and orbifold models
Dijkgraaf, R.; Pasquier, V.; Roche, P.
1991-01-01
We construct non trivial quasi Hopf algebras associated to any finite group G and any element of H3( G, U(1)). We analyze in details the set of representations of these algebras and show that we recover the main interesting datas attached to particular orbifolds of Rational Conformal Field Theory or equivalently to the topological field theories studied by R. Dijkgraaf and E. Witten. This leads us to the construction of the R-matrix structure in non abelian RCFT orbifold models.

Let X be a Hopf manifolds with an Abelian fundamental group. E is a holomorphic vector bundle of rank r with trivial pull-back to W = Cn - {0}. We prove the existence of a non-vanishing section of L(×) E for some line bundle on X and study the vector bundles filtration structure of E. These generalize the results of D. Mall about structure theorem of such a vector bundle E.

Conditions under which a function generates a multiresolution analysis are investigated. The definition of the spectral function of a shift invariant space is generalized from $\\mathbb{R}^n$ to a locally compact abelian group and the union density and intersection triviality properties of a multiresolution analysis are characterized in terms of the spectral functions. Finally, all multiresolution analysis conditions are characterized in terms of the scaling and the spectral functions.
A (k+1)-Slope Theorem for the k-Dimensional Infinite Group Relaxation
Basu, Amitabh; Köppe, Matthias; Molinaro, Marco
2011-01-01
We prove that any minimal valid function for the k-dimensional infinite group relaxation that is piecewise linear with at most k+1 slopes and does not factor through a linear map with non-trivial kernel is extreme. This generalizes a theorem of Gomory and Johnson for k=1, and Cornuejols and Molinaro for k=2.
Transitive conformal holonomy groups
Alt, Jesse
2011-01-01
For $(M,[g])$ a conformal manifold of signature $(p,q)$ and dimension at least three, the conformal holonomy group $\\mathrm{Hol}(M,[g]) \\subset O(p+1,q+1)$ is an invariant induced by the canonical Cartan geometry of $(M,[g])$. We give a description of all possible connected conformal holonomy groups which act transitively on the M\\"obius sphere $S^{p,q}$, the homogeneous model space for conformal structures of signature $(p,q)$. The main part of this description is a list of all such groups which also act irreducibly on $\\R^{p+1,q+1}$. For the rest, we show that they must be compact and act decomposably on $\\R^{p+1,q+1}$, in particular, by known facts about conformal holonomy the conformal class $[g]$ must contain a metric which is locally isometric to a so-called special Einstein product.

2002-01-01
Diagonal invariant ideals of Toeplitz algebras defined on discrete groups are introduced and studied. In terms of isometric representations of Toeplitz algebras associated with quasi-ordered groups, a character of a discrete group to be amenable is clarified. It is proved that when G is Abelian, a closed two-sided non-trivial ideal of the Toeplitz algebra defined on a discrete Abelian ordered group is diagonal invariant if and only if it is invariant in the sense of Adji and Murphy, thus a new proof of their result is given.

The dermatology acting internship.
Stephens, John B; Raimer, Sharon S; Wagner, Richard F
2011-07-15
Acting internships are an important component of modern day medical school curriculum. Several specialties outside of internal medicine now offer acting internship experiences to fourth year medical students. We have found that a dermatology acting internship is a valuable experience for fourth year medical students who are interested in pursuing a residency in dermatology. Our experience with the dermatology acting internship over the 2010-2011 academic year is described.

Indirect speech acts are frequently used in verbal communication, the interpretation of them is of great importance in order to meet the demands of the development of students' communicative competence. This paper, therefore, intends to present Searle' s indirect speech acts and explore the way how indirect speech acts are interpreted in accordance with two influential theories. It consists of four parts. Part one gives a general introduction to the notion of speech acts theory. Part two makes an elaboration upon the conception of indirect speech act theory proposed by Searle and his supplement and development of illocutionary acts. Part three deals with the interpretation of indirect speech acts. Part four draws implication from the previous study and also serves as the conclusion of the dissertation.
Group dualities, T-dualities, and twisted K-theory
Mathai, Varghese
2016-01-01
This paper explores further the connection between Langlands duality and T-duality for compact simple Lie groups, which appeared in work of Daenzer-Van Erp and Bunke-Nikolaus. We show that Langlands duality gives rise to isomorphisms of twisted K-groups, but that these K-groups are trivial except in the simplest case of SU(2) and SO(3). Along the way we compute explicitly the map on $H^3$ induced by a covering of compact simple Lie groups, which is either 1 or 2 depending in a complicated way on the type of the groups involved. We also give a new method for computing twisted K-theory using the Segal spectral sequence, giving simpler computations of certain twisted K-theory groups of compact Lie groups relevant for D-brane charges in WZW theories and rank-level dualities. Finally we study a duality for orientifolds based on complex Lie groups with an involution.

This project is currently under contract for research through the Department of Homeland Security until 2011. The group I was responsible for studying has to remain confidential so as not to affect the current project. All dates, reference links and authors, and other distinguishing characteristics of the original group have been removed from this report. All references to the name of this group or the individual splinter groups has been changed to 'Group X'. I have been collecting texts from a variety of sources intended for the use of recruiting and radicalizing members for Group X splinter groups for the purpose of researching the motivation and intent of leaders of those groups and their influence over the likelihood of group radicalization. This work included visiting many Group X websites to find information on splinter group leaders and finding their statements to new and old members. This proved difficult because the splinter groups of Group X are united in beliefs, but differ in public opinion. They are eager to tear each other down, prove their superiority, and yet remain anonymous. After a few weeks of intense searching, a list of eight recruiting texts and eight radicalizing texts from a variety of Group X leaders were compiled.
Short Conjugators in Solvable Groups
Sale, Andrew W
2011-01-01
We give an upper bound on the size of short conjugators in certain solvable groups. Diestel-Leader graphs, which are a horocyclic product of trees, are discussed briefly and used to study the lamplighter groups. The other solvable groups we look at can be recognised in a similar vein, as groups which act on a horocyclic product of well known spaces. These include the Baumslag-Solitar groups BS(1,q) and semidirect products of Z^n with Z^k. Results can also be applied to the conjugacy of parabolic elements in Hilbert modular groups and to elements in 3-manifold groups.

Quantum measurement act as a "speech act"

The reduction of the state vector is in this perspective an intersubjectice -- or better a-subjective -- symbolic process. I then give some perspectives on applications to the ``Mind-Body problem''.

Assume that each completely irrational noncommutative torus is realized as an inductive limit of circle algebras, and that for a completely irrational noncommutative torus Aω of rank m there are a completely irrational noncommutative torus Aρ of rank m and a positive integer d such that tr(Aω) = 1/d. tr(Aρ). It is proved that the set of all C*-algebras of sections of locally trivial C*-algebra bundles over S2 with fibres Aω has a group structure, denoted by πs1(Aut(Aω)), which is isomorphic to Z. if d > 1 and {0} if d > 1. Let Bcd be a cd-homogeneous C*-algebra over S2 × T2 of which no non-trivial matrix algebra can be factored out. The spherical noncommutative torus Scdρ is defined by twisting C*(T2 × Zm-2) in Bcd C*(Zm-2) by a totally skew multiplier ρ on T2 × Zm-2. It is shown that Scdρ Mp∞ is isomorphic to C(S2) C*(T2 × Zm-2,ρ) Mcd(C) Mp∞ if and only if the set of prime factors of cd is a subset of the set of prime factors of p.

We compute explicitly the action of the group of affine diffeomorphisms on the relative homology of two remarkable origamis discovered respectively by Forni (in genus 3) and Forni-Matheus (in genus 4). We show that, in both cases, the action on the non trivial part of the homology is through finite groups. In particular, the action on some 4-dimensional invariant subspace of the homology leaves invariant a root system of $D_4$ type. This provides as a by-product a new proof of (slightly stronger versions of) the results of Forni and Matheus: the non trivial Lyapunov exponents of the Kontsevich-Zorich cocycle for the Teichmuller disks of these two origamis are equal to zero.
The signed permutation group on Feynman graphs
Purkart, Julian
2016-08-01
The Feynman rules assign to every graph an integral which can be written as a function of a scaling parameter L. Assuming L for the process under consideration is very small, so that contributions to the renormalization group are small, we can expand the integral and only consider the lowest orders in the scaling. The aim of this article is to determine specific combinations of graphs in a scalar quantum field theory that lead to a remarkable simplification of the first non-trivial term in the perturbation series. It will be seen that the result is independent of the renormalization scheme and the scattering angles. To achieve that goal we will utilize the parametric representation of scalar Feynman integrals as well as the Hopf algebraic structure of the Feynman graphs under consideration. Moreover, we will present a formula which reduces the effort of determining the first-order term in the perturbation series for the specific combination of graphs to a minimum.

We describe Green's relations on the semigroups $\\mathscr{B}(G)$, $\\mathscr{B}^+(G)$, $\\bar{\\mathscr{B}}(G)$ and $\\bar{\\mathscr{B}}\\,^+(G)$, their bands and show that they are simple, and moreover the semigroups $\\mathscr{B}(G)$ and $\\mathscr{B}^+(G)$ are bisimple. We show that for a commutative linearly ordered group $G$ all non-trivial congruences on the semigroup $\\mathscr{B}(G)$ (and $\\mathscr{B}^+(G)$) are group congruences if and only if the group $G$ is archimedean. Also we describe the structure of group congruences on the semigroups $\\mathscr{B}(G)$, $\\mathscr{B}^+(G)$, $\\bar{\\mathscr{B}}(G)$ and $\\bar{\\mathscr{B}}\\,^+(G)$.

Written by one of the subject’s foremost experts, this book focuses on the central developments and modern methods of the advanced theory of abelian groups, while remaining accessible, as an introduction and reference, to the non-specialist. It provides a coherent source for results scattered throughout the research literature with lots of new proofs. The presentation highlights major trends that have radically changed the modern character of the subject, in particular, the use of homological methods in the structure theory of various classes of abelian groups, and the use of advanced set-theoretical methods in the study of undecidability problems. The treatment of the latter trend includes Shelah’s seminal work on the undecidability in ZFC of Whitehead’s Problem; while the treatment of the former trend includes an extensive (but non-exhaustive) study of p-groups, torsion-free groups, mixed groups, and important classes of groups arising from ring theory.

Reduction of the Hall-Paige conjecture to sporadic simple groups
Wilcox, Stewart
2010-01-01
A complete mapping of a group $G$ is a permutation $\\phi:G\\rightarrow G$ such that $g\\mapsto g\\phi(g)$ is also a permutation. Complete mappings of $G$ are equivalent to tranversals of the Cayley table of $G$, considered as a latin square. In 1953, Hall and Paige proved that a finite group admits a complete mapping only if its Sylow-2 subgroup is trivial or non-cyclic. They conjectured that this condition is also sufficient. We prove that it is sufficient to check the conjecture for the 26 sporadic simple groups and the Tits group.

Full Text Available O problema da determinação da ação humana ocupou a filosofia durante séculos. O presente ensaio procura contribuir para esse debate através da proposta de duas teses filosóficas. A primeira tese defende que toda a ação humana se organiza numa estrutura de espera de algo que determine a consciência. Toda a iniciativa e todo o ato voluntário dependem de algo que surge no fluxo de consciência. Neste sentido, o sujeito parece ser visitado do exterior por algo que irá iniciar o comportamento. Em defesa desta tese apresentam-se relatos fenomenológicos do processo de decisão, registos históricos de eventos mentais como visitações, representações literárias e teorias filosóficas do tempo. Em particular, mostra-se que as teorias sobre a dimensão corpuscular ou granular do tempo e do fluxo da consciência são especialmente relevantes para a explicação da capacidade de atuação dos seres humanos. Em complemento, propõe-se um inventário dos grandes temas que organizam a ação. Trabalham-se conteúdos culturais ligados às universidades, à internet e à literatura. Defende-se uma segunda tese filosófica segundo a qual os seres humanos só se interessam maioritariamente por si mesmos. O ensaio termina com a defesa da ideia de que a filosofia, a ciência e a religião não têm meios racionais para explicar a atuação humana, restando apenas a abordagem sapiencial. As várias linhas de pensamento deste ensaio são unificadas pela ideia de que a trivialidade da vida humana esconde problemas intelectuais dignos de investigação. Palavras-chave: determinação do comportamento; autodeterminação; Bestimmung; Selbsbestimmung; sobretons psíquicos; teoria granular da consciência; fenomenologia da ação.

On combining significances. Some trivial examples
Krasnikov, N V
2010-01-01
For Poisson distribution $Pois(n, \\lambda)$ with $\\lambda \\gg 1$, $n \\gg 1$ we propose to determine significance as $S = \\frac{n_{obs}-\\lambda}{\\sqrt{\\lambda}}$. The significance $S$ coincides up to sign with often used significance. For experiments which measure the same quantities the natural but not unique rule for significance combining is $S_{comb}(S_1, S_2) = \\frac{S_1\\sigma_1+S_2\\sigma_2}{\\sqrt{\\sigma^2_1+\\sigma^2_2}}$, where $\\sigma_1$ and $\\sigma_2$ are variations. We also propose the rule for significances combining for the case with systematic errors.

Full Text Available BACKGROUND: Asthma and rhinitis often coexist, which potentially increases the disease severity and can negatively impact a patients' quality of life. However, there are few reports based on data obtained from the International Study of Asthma and Allergies in Childhood examining asthma severity in combination with rhinitisrelated symptoms. OBJECTIVE: To demonstrate whether current rhinitis and current rhinoconjunctivitis are associated with the development of asthma or its increasing severity in Brazilian adolescents. METHODS: The prevalence of current asthma was correlated with the prevalence of current rhinitis and current rhinoconjunctivitis in adolescents (13 to 14 year olds from 16 Brazilian centers (based on Spearman's rank correlation index. The influence of current rhinitis and current rhinoconjunctivitis on asthma presentation was also evaluated using the chi-squared test and was expressed as odds ratios with 95% confidence intervals (95%CI. RESULTS: A significant positive correlation was observed between the prevalence of current asthma and current rhinitis (rs = 0.82; 95%CI: 0.60-0.93, p< 0.0001 and between the prevalence of current asthma and current rhinoconjunctivitis (rs = 0.75; 95%CI: 0.47-0.89, p < 0.0001. Current rhinitis was associated with a significantly increased risk of current asthma and of more severe asthma. Similar results were observed for current rhinoconjunctivitis. CONCLUSION: In this epidemiologic study of Brazilian adolescents, the presence of current rhinitis and current rhinoconjunctivitis was associated with a high risk of developing asthma and increased asthma severity. The mutual evaluation of rhinitis and asthma is necessary to establish an adequate treatment plan.

@@ Historically,re-selection,pedigree,and mass selection breeding methods have been used to develop open-pollinated cultivars of Upland cotton (Gossypium hirsutum L.).Due to the predominance of these breeding methods,we hypothesize that modern cultivars,as opposed to obsolete cultivars,have accumulated additive genetic effects over time.
Gauge theories with non-trivial backgrounds
Binosi, Daniele
2014-01-01
We review our most recent results in formulating gauge theories in the presence of a background field on the basis of symmetry arguments only. In particular we show how one can gain full control over the dependence on the background field of the effective action, and how the so-called background field method emerges naturally from the requirement of invariance under the BRST and antiBRST symmetries.

In recent years the amount of digital data in the world has risen immensely. But, the more information exists, the greater is the possibility of its unwanted disclosure. Thus, the data privacy protection has become a pressing problem of the present time. The task of individual privacy-preserving is being thoroughly studied nowadays. At the same time, the problem of statistical disclosure control for collective (or group) data is still open. In this paper we propose an effective and relatively simple (wavelet-based) way to provide group anonymity in collective data. We also provide a real-life example to illustrate the method.

New insights in particle dynamics from group cohomology
Aldaya, V; Guerrero, J
2002-01-01
The dynamics of a particle moving in background electromagnetic and gravitational fields is revisited from a Lie group cohomological perspective. Physical constants characterizing the particle appear as central extension parameters of a group which is obtained from a centrally extended kinematical group (Poincare or Galilei) by making some subgroup local. The corresponding dynamics is generated by a vector field inside the kernel of a pre-symplectic form which is derived from the canonical left-invariant 1-form on the extended group. A non-relativistic limit is derived from the geodesic motion via an Inoenue-Wigner contraction. A deeper analysis of the cohomological structure reveals the possibility of a new force associated with a non-trivial mixing of gravity and electromagnetism leading to, in principle, testable predictions.

The Advanced Communications Technology Satellite (ACTS) to be launched in 1993 is briefly introduced. Its multibeam antenna, consisting of electrically similar 30 GHz receive and 20 GHz transmit offset Cassegrain systems, both utilizing orthogonal polarizations, is described. Dual polarization is achieved by using one feed assembly for each polarization in conjunction with nested front and back subreflectors, the gridded front subreflector acting as a window for one polarization and a reflector for the other. The antennas produce spot beams with approximately 0.3 degree beamwidth and gains of approximately 50 dbi. High surface accuracy and high edge taper produce low sidelobe levels and high cross-polarization isolation. A brief description is given of several Ka-band components fabricated for ACTS. These include multiflare antenna feedhorns, beam-forming networks utilizing latching ferrite waveguide switches, a 30 GHz HEMT low-noise amplifier and a 20 GHz TWT power amplifier.

We present preliminary results from a study of the neutral hydrogen (HI) properties of an X-ray selected sample of nearby loose galaxy groups. This forms part of a multi-wavelength investigation (X-ray, optical and radio) of the formation and evolution of galaxies within a group environment. Some initial findings of an ATNF Parkes Multibeam wide-area neutral hydrogen imaging survey of 17 nearby galaxy groups include two new, potentially isolated clouds of HI in the NGC 1052 and NGC 5044 groups and significant amounts of HI within the group virial radii of groups NGC 3557 and IC 1459 - two groups with complex X-ray structures that suggest they may still be in the act of virialisation. Here we present ATCA high-resolution synthesis-imaging follow-up observations of the distribution and kinematics of HI in these four groups.

Service dogs are sanctioned by the Americans with Disabilities Act as having protected rights allowing them to assist owners with disabilities. These dogs are appearing with increasing frequency in healthcare settings, and it is important for healthcare providers to understand the rules and regulations given to service animals and owners. We discuss processes that transpired when a service dog was brought into a psychodynamic psychotherapy group. The purpose of this paper is to highlight the unintended consequences of the Americans with Disabilities Act of 2010 as it concerns service dogs and the impact on the group process. Problems resulting from the introduction of service dogs into therapy groups should be anticipated and explicitly discussed in the course of the group's transactions.

On the Defect Group of a 6D SCFT
Del Zotto, Michele; Park, Daniel S; Rudelius, Tom
2015-01-01
We use the F-theory realization of 6D superconformal field theories (SCFTs) to study the corresponding spectrum of stringlike, i.e. surface defects. On the tensor branch, all of the stringlike excitations pick up a finite tension, and there is a corresponding lattice of string charges, as well as a dual lattice of charges for the surface defects. The defect group is data intrinsic to the SCFT and measures the surface defect charges which are not screened by dynamical strings. When non-trivial, it indicates that the associated theory has a partition vector rather than a partition function. We compute the defect group for all known 6D SCFTs, and find that it is just the abelianization of the discrete subgroup of U(2) which appears in the classification of 6D SCFTs realized in F-theory. We also explain how the defect group specifies defining data in the compactification of a (1,0) SCFT.

Uproar over Milk Substitutes Act.
1993-11-15
Health policy activists lobbied 7 years for the Infant Milk Substitutes, Feeding Bottles and Infant Food Bill. Proponents of the bill say that it basically curtails unethical marketing practices, not the sales of baby foods, and argue that it was conceived to reduce the trend of mothers over-diluting commercial milk in order to reduce household expenses as well as stem the potential erosion of knowledge on locally available weaning foods. Even though the bill will become an Act only after its rules and regulations have been finalized, the government has already banned baby food advertisements on television and in other electronic media under its control. Women's groups now argue that the bill tends to focus almost exclusively upon the welfare of children and compromises the position of women who can not lactate adequately. Moreover, they hold that the bill may be used to compel wives to stay out of the formal workforce so that they may feed their babies. The intention of the bill may be meaningless without complementary legislation addressing the problems of working mothers. Specifically, amendments to the Maternity Benefits Act of 1961 would extend maternity leave to 4 months after delivery and lengthen the duration of nursing breaks. It is, however, feared that these changes may reduce employment prospects for women.

Full Text Available Speech Act Theory (SAT, a theory in pragmatics, is an attempt to describe what happens during linguistic interactions. Inherent within SAT is the idea that language forms and intentions are relatively formulaic and that there is a direct correspondence between sentence forms (for example, in terms of structure and lexicon and the function or meaning of an utterance. The contention offered in this paper is that when such a correspondence does not exist, as in indirect speech utterances, this creates challenges for English second language speakers and may result in miscommunication. This arises because indirect speech acts allow speakers to employ various pragmatic devices such as inference, implicature, presuppositions and context clues to transmit their messages. Such devices, operating within the non-literal level of language competence, may pose challenges for ESL learners.

All of the 4000 infants who die daily in India have been bottle fed. Most of these infants die from infections which are typically caused by bottle feeding. Considerable research has shown that human breast milk ideally suits babies' needs. Human breast milk protects infants from several infections and allergies, such that the breastfed infant is 25 times less likely than the bottle fed infant to die due to diarrhea and pneumonia. Comparative studies have even found breastfed babies to have higher IQs than bottle fed ones. Detrimental maternity home practices, adverse social factors, and the unethical and aggressive marketing strategy adopted by the manufacturers of infant milk substitutes and feeding bottles are the major factors responsible for the erosion of the practice of breastfeeding. These factors are discussed. The Infant Milk Substitutes, Feeding Bottles, and Infant Foods Act prohibits the advertisement and promotion of feeding bottles and infant milk substitutes by unethical marketing strategies. Violations of the act are punishable by imprisonment and a heavy fine. The act and the need for its passage are discussed.
Group selection in behavioral evolution.
Rachlin, Howard
2017-09-09
How may patterns of behavior change over an organism's lifetime? The answer is that they evolve (behavioral evolution) as species evolve over generations (biological evolution). In biological evolution, under certain conditions, groups of cooperative organisms would be selected over groups of non-cooperative organisms, even when cooperation imposes a cost to individuals. Analogously, in behavioral evolution, patterns of acts may be selected even when each individual act in the pattern is costly. Although there is considerable debate among biologists whether the conditions for group selection are met in biological evolution, it is argued here that they are met in behavioral evolution (as well as in cultural evolution). The article shows how selection of patterns can explain the learning of self-control and altruism. Copyright © 2017 Elsevier B.V. All rights reserved.

The Wilson Renormalisation Group Applied to the Potential in NN Scattering

Nonrelativistic two-body scattering by a short-ranged potential is studied using the renormalisation group. Two fixed points are identified: a trivial one and one describing systems with a bound state at zero energy. The eigenvalues of the linearised renormalisation group are used to assign a systematic power-counting to terms in the potential near each of these fixed points. The expansion around the nontrivial fixed point defines a power counting scheme which is equivalent to the effective-range expansion.

The individual...... the individuals evaluate, interpret and act (Bourdieu 1984), and how this affects their choice to walk. Therefore it could be questioned if whether an assessment of the physical environment is sufficient to identify all the factors that influence the individual perception of ‘walkability’, or if other influencing...
Admissible groups, symmetric factor sets, and simple algebras
Directory of Open Access Journals (Sweden)
R. A. Mollin
1984-01-01
Full Text Available Let K be a field of characteristic zero and suppose that D is a K-division algebra; i.e. a finite dimensional division algebra over K with center K. In Mollin [1] we proved that if K contains no non-trivial odd order roots of unity, then every finite odd order subgroup of D* the multiplicative group of D, is cyclic. The first main result of this paper is to generalize (and simplify the proof of the above. Next we generalize and investigate the concept of admissible groups. Finally we provide necessary and sufficient conditions for a simple algebra, with an abelian maximal subfield, to be isomorphic to a tensor product of cyclic algebras. The latter is achieved via symmetric factor sets.

Leaning on the derived results conducted by Central Mindanao University Phil-LiDAR 2.B.11 Image Processing Component, the paper attempts to provides the application of the Light Detection and Ranging (LiDAR) derived products in arriving quality Landcover classification considering the theoretical approach of data analysis principles to minimize the common problems in image classification. These are misclassification of objects and the non-distinguishable interpretation of pixelated features that results to confusion of class objects due to their closely-related spectral resemblance, unbalance saturation of RGB information is a challenged at the same time. Only low density LiDAR point cloud data is exploited in the research denotes as 2 pts/m2 of accuracy which bring forth essential derived information such as textures and matrices (number of returns, intensity textures, nDSM, etc.) in the intention of pursuing the conditions for selection characteristic. A novel approach that takes gain of the idea of object-based image analysis and the principle of allometric relation of two or more observables which are aggregated for each acquisition of datasets for establishing a proportionality function for data-partioning. In separating two or more data sets in distinct regions in a feature space of distributions, non-trivial computations for fitting distribution were employed to formulate the ideal hyperplane. Achieving the distribution computations, allometric relations were evaluated and match with the necessary rotation, scaling and transformation techniques to find applicable border conditions. Thus, a customized hybrid feature was developed and embedded in every object class feature to be used as classifier with employed hierarchical clustering strategy for cross-examining and filtering features. This features are boost using machine learning algorithms as trainable sets of information for a more competent feature detection. The product classification in this

Conversation, speech acts, and memory.
Holtgraves, Thomas
2008-03-01
Speakers frequently have specific intentions that they want others to recognize (Grice, 1957). These specific intentions can be viewed as speech acts (Searle, 1969), and I argue that they play a role in long-term memory for conversation utterances. Five experiments were conducted to examine this idea. Participants in all experiments read scenarios ending with either a target utterance that performed a specific speech act (brag, beg, etc.) or a carefully matched control. Participants were more likely to falsely recall and recognize speech act verbs after having read the speech act version than after having read the control version, and the speech act verbs served as better recall cues for the speech act utterances than for the controls. Experiment 5 documented individual differences in the encoding of speech act verbs. The results suggest that people recognize and retain the actions that people perform with their utterances and that this is one of the organizing principles of conversation memory.
The Cherenkov Radiation for Non-Trivial Systems; La Radiacion Cherenkov en Sistemas No Triviales

2002-07-01
The charge pathways and the dielectric properties of the medium are two essential aspects to be considered in the study of the emission of Cherenkov radiation. We described the evolution of the Cherenkov wavefront when the charges follow circular or helical pathways. Also we derive expressions for the refractive Index in different transparent media (solid, liquid or gas), focusing our attention on optically active plasmas. The optical analogies between the plasma and the birefringent crystals is studied in detail. Finally, we list some examples of plasmas, which can be considered emitters of Cherenkov radiation.

Canonical group quantization and boundary conditions
Energy Technology Data Exchange (ETDEWEB)
Jung, Florian
2012-07-16
In the present thesis, we study quantization of classical systems with non-trivial phase spaces using the group-theoretical quantization technique proposed by Isham. Our main goal is a better understanding of global and topological aspects of quantum theory. In practice, the group-theoretical approach enables direct quantization of systems subject to constraints and boundary conditions in a natural and physically transparent manner -- cases for which the canonical quantization method of Dirac fails. First, we provide a clarification of the quantization formalism. In contrast to prior treatments, we introduce a sharp distinction between the two group structures that are involved and explain their physical meaning. The benefit is a consistent and conceptually much clearer construction of the Canonical Group. In particular, we shed light upon the 'pathological' case for which the Canonical Group must be defined via a central Lie algebra extension and emphasise the role of the central extension in general. In addition, we study direct quantization of a particle restricted to a half-line with 'hard wall' boundary condition. Despite the apparent simplicity of this example, we show that a naive quantization attempt based on the cotangent bundle over the half-line as classical phase space leads to an incomplete quantum theory; the reflection which is a characteristic aspect of the 'hard wall' is not reproduced. Instead, we propose a different phase space that realises the necessary boundary condition as a topological feature and demonstrate that quantization yields a suitable quantum theory for the half-line model. The insights gained in the present special case improve our understanding of the relation between classical and quantum theory and illustrate how contact interactions may be incorporated.

Evil acts not evil people: their characteristics and contexts.
Horne, Michael
2008-11-01
The problem of evil has vexed philosophers and theologians for centuries and anthropologists, sociologists, psychoanalysts and analytical psychologists in more recent times. Numerous theories have been proposed but there is still little agreement on such basic questions as the nature of evil, what constitutes and motivates an evil act, and how we resolve conflicts between individuals and groups in which evil acts are being committed. I am proposing that evil should be used as an adjective, and not as a noun. As such it should be employed to qualify acts of persons rather than their character. This change would enable us to eschew foundational explanations of evil and, therefore, to examine evil acts in their contexts and so better discern their nature and motivation. I will contend that evil acts begin when an individual makes, or members of a group make, assertions about the 'naturalness' of their own acts and, correspondingly, the 'unnaturalness' of the acts of others. I will suggest that this results from the anxiety that ensues when they cannot adequately signify their experience of these acts. When this occurs, those so treated are dispossessed of their 'personhood', allowing members of the 'natural' group to violate their 'boundaries' with impunity. These violations can range from the relatively innocuous such as being ignored to the extreme such as genocide. I am asserting that all these acts should be termed evil as they derive from the same semiotic process of 'naturalizaton'. I will discuss ways of preventing individuals or groups from embarking on the process of 'naturalization' and describe the types of contexts that might reduce or eliminate the commission of evil acts by those already engaged in their perpetration. To demonstrate these ideas I will use examples from my personal experience, from analytic theory and from the 'troubles' in Northern Ireland.
Duality group actions on fermions
Pantev, Tony; Sharpe, Eric
2016-11-01
In this short paper we look at the action of T-duality and string duality groups on fermions, in maximally-supersymmetric theories and related theories. Briefly, we argue that typical duality groups such as SL(2 , ℤ) have sign ambiguities in their actions on fermions, and propose that pertinent duality groups be extended by ℤ2, to groups such as the metaplectic group. Specifically, we look at duality groups arising from mapping class groups of tori in M theory compactifications, T-duality, ten-dimensional type IIB S-duality, and (briefly) four-dimensional N = 4 super Yang-Mills, and in each case, propose that the full duality group is a nontrivial ℤ2 extension of the duality group acting on bosonic degrees of freedom, to more accurately describe possible actions on fermions. We also walk through U-duality groups for toroidal compactifications to nine, eight, and seven dimensions, which enables us to perform cross-consistency tests of these proposals.

Sur les Automorphismes de Groupes Libres et de Groupes de Surface
Paulin, Frédéric
2011-01-01
The special linear groups, the mapping class groups of surfaces, the outer autormorphism groups of free groups appear in numerous domains. Their analogies, developped in particular in K. Vogtmann's work, have been written about a lot. In this report, we concentrate on the contractible spaces on which these groups act in an analogous way, on the common properties of their subgroups, and on the similar (or conjecturally similar) properties of their asymptotic geometry.

Among a sample of Belgian high school boys, the author attempted to determine on the basis of social identity theory (H. Tajfel & J. C. Turner, 1979) whether an outgroup's relevancy in intergroup comparisons influences the amount of intergroup discrimination. Relevancy was manipulated by the use of 2 trivial categorization dimensions that were orthogonally crossed. In 1 of the crossed categorization conditions, this procedure resulted in the formation of 4 groups, whereas in the 2nd condition, only 2 of these groups were effectively formed. Nevertheless, the participants in both conditions were instructed to evaluate 4 groups--either 4 actual groups (1st condition) or 2 actual and 2 hypothetical groups (2nd condition). In both conditions, the intergroup evaluations exhibited the same pattern--that is, they did not differentiate their ingroups from the partly overlapping groups but were clearly biased against the double outgroup.
Topological Groups and Dugundji Compacta
Uspenskiĭ, V. V.
1990-02-01
A compact space X is called a Dugundji compactum if for every compact Y containing X, there exists a linear extension operator \\Lambda:\\ C(X)\\to C(Y) which preserves nonnegativity and maps constants into constants. It is known that every compact group is a Dugundji compactum. In this paper we show that compacta connected in a natural way with topological groups enjoy the same property. For example, in each of the following cases, the compact space X is a Dugundji compactum:1) X is a retract of an arbitrary topological group;2) X=\\beta P, where P is a pseudocompact space on which some \\aleph_0-bounded topological group acts transitively and continuously.Bibliography: 57 titles.

When Gideon Welles, U.S. Secretary of the Navy, sat down to write his diary entry on September 26, 1862, his thoughts turned once more to colonization. President Lincoln was an ardent proponent of colonization, “the government-promoted settlement of black Americans in Africa or some other location......” and based on the recurring cabinet discussions, Welles understood that “Great Britain, Denmark and perhaps other powers would take them [the black population].” Since at least 1860, Denmark had encouraged the American government to send the “quite uncivilized (…) Africans liberated” from slave ships to St...... and the United States signed an act on July 19, 1862, wherein the U.S. Navy agreed to unload “all negroes, mulattoes, or persons of color, delivered from on board vessels seized in the prosecution of the slave trade.” Yet, despite the two countries’ mutual interests in employing “laborers of African Extraction...

The holder consist of: a stationary base portion capable of being fixed to a cutter head of an excavation machine and having an integral extension therefrom with a bore hole therethrough to accommodate a pin shaft; a movable portion coextensive with the base having a pin shaft integrally extending therefrom that is insertable in the bore hole of the base member to permit the moveable portion to rotate about the axis of the pin shaft; a recess in the movable portion of the holder to accommodate a shank of a bit; and a biased spring disposed in adjoining openings in the base and moveable portions of the holder to permit the moveable portion to pivot around the pin shaft during cutting action of a bit fixed in a turret to allow front, mid and back positions of the bit during cutting to lessen creation of small chip amounts and resharpen the bit during excavation use.

The author understands the interpreting act as an attempt to perceive what happens in the transference/countertransference field and not just what happens in the patient's mind. Interpretation transcends mere intellectual communication. It is also an experience in which analysts' emotions work as an important instrument in understanding their patients. Interpretation is seen to possess manifest as well as latent content; the latter would contain the analysts' feelings, emotions and personality. The unconscious content of an interpretation does not inconvenience or preclude the development of the analytic process, but, on the contrary, it allows new associative material to emerge, and it transforms the analytic session into a human relationship. Analysts' awareness of this content derived from patients' apperceptions is a significant instrument for understanding what is happening in the analytic relationship, and what transpires in these sessions provides fundamental elements for analysts' self-analysis. Some clinical examples demonstrate these occurrences in analytic sessions, and how they can be apprehended and used for a better understanding of the patient. The author also mentions the occurrence of difficulties during the analytic process. These difficulties are often the result of lapses in an analyst's perception related to unconscious elements of the relationship.

The benefits that will be offered by the NASA-sponsored communication spacecraft ACTS which is scheduled for launch in 1992 are described together with examples of demonstrations on proposed data, video, and voice applications supported by the advanced ACTS technologies. Compared to existing satellite service, the ACTS will provide lower cost, better service, greater convenience, and improved service reliability of telecommunications to customers around the world. In addition, the pioneering ACTS technology will provide many capabilities qualitatively different from those of current satellite systems, such as on-demand assignment, frequency reuse, and the flexible targeting of spot beams directly to the very-small-aperture terminals at customer premises.

We rewrite the recently derived cubic action of Double Field Theory on group manifolds http://dx.doi.org/10.1007/JHEP02(2015)001 in terms of a generalized metric and extrapolate it to all orders in the fields. For the resulting action, we derive the field equations and state them in terms of a generalized curvature scalar and a generalized Ricci tensor. Compared to the generalized metric formulation of DFT derived from tori, all these quantities receive additional contributions related to the non-trivial background. It is shown that the action is invariant under its generalized diffeomorphisms and 2D-diffeomorphisms. Imposing additional constraints relating the background and fluctuations around it, the precise relation between the proposed generalized metric formulation of DFT{sub WZW} and of original DFT from tori is clarified. Furthermore, we show how to relate DFT{sub WZW} of the WZW background with the flux formulation of original DFT.

Watson-Crick pairing, the Heisenberg group and Milnor invariants.
Gadgil, Siddhartha
2009-07-01
We study the secondary structure of RNA determined by Watson-Crick pairing without pseudo-knots using Milnor invariants of links. We focus on the first non-trivial invariant, which we call the Heisenberg invariant. The Heisenberg invariant, which is an integer, can be interpreted in terms of the Heisenberg group as well as in terms of lattice paths. We show that the Heisenberg invariant gives a lower bound on the number of unpaired bases in an RNA secondary structure. We also show that the Heisenberg invariant can predict allosteric structures for RNA. Namely, if the Heisenberg invariant is large, then there are widely separated local maxima (i.e., allosteric structures) for the number of Watson-Crick pairs found.

Spreading of cooperative behaviour across interdependent groups
Jiang, Luo-Luo
2013-01-01
Recent empirical research has shown that links between groups reinforce individuals within groups to adopt cooperative behaviour. Moreover, links between networks may induce cascading failures, competitive percolation, or contribute to efficient transportation. Here we show that there in fact exists an intermediate fraction of links between groups that is optimal for the evolution of cooperation in the prisoner's dilemma game. We consider individual groups with regular, random, and scale-free topology, and study their different combinations to reveal that an intermediate interdependence optimally facilitates the spreading of cooperative behaviour between groups. Excessive between-group links simply unify the two groups and make them act as one, while too rare between-group links preclude a useful information flow between the two groups. Interestingly, we find that between-group links are more likely to connect two cooperators than in-group links, thus supporting the conclusion that they are of paramount impor...

Constructive Tensorial Group Field Theory II: The $U(1)-T^4_4$ Model
Lahoche, Vincent
2015-01-01
In this paper we continue our program of non-pertubative constructions of tensorial group field theories (TGFT). We prove analyticity and Borel summability in a suitable domain of the coupling constant of the simplest super-renormalizable TGFT which contains some ultraviolet divergencies, namely the color-symmetric quartic melonic rank-four model with Abelian $U(1)$ gauge invariance, nicknamed $U(1)-T^4_4$. We use a multiscale loop vertex expansion. It is an extension of the loop vertex expansion (the basic constructive technique for non-local theories) which is required for theories that involve non-trivial renormalization.

Right to life -as the prohibition of intentionally and arbitrarily taking life, even with authorization of the concerned one- is an internationally recognized right. In many countries, debate regarding euthanasia is more centered in its convenience, social acceptability and how it is regulated, than in its substantial legitimacy. Some argue that euthanasia should be included as part of clinical practice of health professionals, grounded on individual's autonomy claims-everyone having the liberty to choose how to live and how to die. Against this, others sustain that life has a higher value than autonomy, exercising autonomy without respecting the right to life would become a serious moral and social problem. Likewise, euthanasia supporters some-times claim a 'right to live with dignity', which must be understood as a personal obligation, referred more to the ethical than to the strictly legal sphere. In countries where it is already legalized, euthanasia practice has extended to cases where it is not the patient who requests this but the family or some healthcare professional, or even the legal system-when they think that the patient is living in a condition which is not worthy to live. Generalization of euthanasia possibly will end in affecting those who need more care, such as elder, chronically ill or dying people, damaging severely personal basic rights. Nature, purpose and tradition of medicine rule out the practice of euthanasia, which ought not be considered a medical act or legitimately compulsory for physicians. Today's medicine counts with effective treatments for pain and suffering, such as palliative care, including sedative therapy, which best preserves persons dignity and keeps safe the ethos of the medical profession.
Pride, Shame and Group Identification
Directory of Open Access Journals (Sweden)
Alessandro eSalice
2016-04-01
Full Text Available Self-conscious emotions such as shame and pride are emotions that typically focus on the self of the person who feels them. In other words, the intentional object of these emotions is assumed to be the subject that experiences them. Many reasons speak in its favor and yet this account seems to leave a question open: how to cash out those cases in which one genuinely feels ashamed or proud of what someone else does?This paper contends that such cases do not necessarily challenge the idea that shame and pride are about the emoting subject. Rather, we claim that some of the most paradigmatic scenarios of shame and pride induced by others can be accommodated by taking seriously the consideration that, in such cases, the subject group-identifies with the other. This is the idea that, in feeling these forms of shame or pride, the subject is conceiving of herself as a member of the same group as the subject acting shamefully or in an admirable way. In other words, these peculiar emotive responses are elicited in the subject insofar as, and to the extent that, she is (or sees herself as being a member of a group – the group to which those who act shamefully or admirably also belong.By looking into the way in which the notion of group identification can allow for an account of hetero-induced shame and pride, this paper attempts to achieve a sort of mutual enlightenment that brings to light not only an important and generally neglected form of self-conscious emotions, but also relevant features of group identification. In particular, it generates evidence for the idea that group identification is a psychological process that the subject does not have to carry out intentionally in the sense that it is not necessarily triggered by the subject’s conative states like desires or intentions.

A gap theorem for the ZL-amenability constant of a finite group
Directory of Open Access Journals (Sweden)
Yemon Choi
2016-12-01
Full Text Available It was shown in [A. Azimifard, E. Samei, N. Spronk, JFA 256 (2009] that the ZL-amenability constant of a finite group is always at least~$1$, with equality if and only if the group is abelian. It was also shown in [A. Azimifard, E. Samei, N. Spronk, op cit.] that for any finite non-abelian group this invariant is at least $301/300$, but the proof relies crucially on a deep result of D. A. Rider on norms of central idempotents in group algebras.Here we show that if $G$ is finite and non-abelian then its ZL-amenability constant is at least $7/4$, which is known to be best possible. We avoid use of Rider's reslt, by analyzing the cases where $G$ is just non-abelian, using calculations from [M. Alaghmandan, Y. Choi, E. Samei, CMB 57 (2014], and establishing a new estimate for groups with trivial centre.

Group typicality, group loyalty and cognitive development.
Patterson, Meagan M
2014-09-01
Over the course of childhood, children's thinking about social groups changes in a variety of ways. Developmental Subjective Group Dynamics (DSGD) theory emphasizes children's understanding of the importance of conforming to group norms. Abrams et al.'s study, which uses DSGD theory as a framework, demonstrates the social cognitive skills underlying young elementary school children's thinking about group norms. Future research on children's thinking about groups and group norms should explore additional elements of this topic, including aspects of typicality beyond loyalty.

Full Text Available Let n be an integer. A group G is said to be n-abelian if the map phi_n that sends g to g^n is an endomorphism of G. Then (xy^n=x^ny^n for all x,y in G, from which it follows [x^n,y]=[x,y]^n=[x,y^n]. It is also easy to see that a group G is n-abelian if and only if it is (1-n-abelian. If nneq 0,1 and G is an n-abelian group, then the quotient group G/Z(G has finite exponent dividing n(n-1. This implies that every torsion-free n-abelian group is abelian. We denote by B_n and C_n the classes of all groups G for which phi_n is a monomorphism and an epimorphism of G, respectively. Then B_0=C_0 contains only the trivial group, B_1=C_1 is the class of all groups, and B_-1=C_-1 is the class of all abelian groups. Furthermore, with |n|>1, G is in B_n if and only if G is an n-abelian group having no elements of order dividing |n|. Similarly, G is in C_n if and only if G is n-abelian and for every g in G there exists an element x in G such that g=x^n. We also set A_n=B_ncap C_n. In this paper we give a characterization for groups in B_n and for groups in C_n. We also obtain an arithmetic description of the set of all integers n such that a group G is in A_n.

Sociological studies into alcohol use seem to find it difficult to deal with the substance itself. Alcohol tends to be reduced to a symbol of a social process and in this way the sociological research loses sight of effects beyond the social. This paper suggests a new theoretical approach...... to the study of alcohol and teenagers' (romantic) relationships, inspired by actor-network theory (ANT). The central feature of ANT is to search for relationships, or rather networks, between all things relevant to the phenomenon. All material and semantic structures, things, persons, discourses, etc....... that influence a given situation are described as actants and are entered into the analysis. The aim of this paper is to propose a way of including materiality in sociological analyses of alcohol and to explore ways of using focus group interview material in ANT-inspired analysis.

Diffusion processes through social groups' dynamics
Apolloni, Andrea
2011-01-01
Axelrod's model describes the dissemination of a set of cultural traits in a society constituted by individual agents. In a social context, nevertheless, individual choices toward a specific attitude are also at the basis of the formation of communities, groups and parties. The membership in a group changes completely the behavior of single agents who start acting according to a social identity. Groups act and interact among them as single entities, but still conserve an internal dynamics. We show that, under certain conditions of social dynamics, the introduction of group dynamics in a cultural dissemination process avoids the flattening of the culture into a single entity and preserves the multiplicity of cultural attitudes. We also considered diffusion processes on this dynamical background, showing the conditions under which information as well as innovation can spread through the population in a scenario where the groups' choices determine the social structure.
Discourse, Statement and Speech Act

Full Text Available Being a component of socio-cultural interaction discourse constitutes a sophisticated cohesion of language form, meaning and performance, i.e. communicative event or act. Cohesion with event and performance let us treat discourse as a certain lifeform, appealing both to communicative interaction and pragmatic environment using the methodology of studies of E. Benveniste, M. Foucault, I. Kecskes, J.R. Searle et al. In linguistics and other fields of humanitarian knowledge the notion of discourse facilitates the integration of studies in humanities. Principles of integration, incorporation into broad humanitarian context reveal some topics of discourse-speech act-utterance interaction which leads to substantive solutions of a number of linguistic topics, in particular, that of an utterance. Logicians determine utterance through proposition; linguists - through sentence, while speech act theory does it by means of illocutionary act. Integrated in a discourse or its part, utterance makes up their integral constituents although not unique ones. In relation to speech acts, utterance happens to be the unique definitional domain synchronically modelling and denoting speech act by means of propositional content. The goal of the research is to show the conditions of interaction and correlation of discourse, speech act and utterance as linguistic constructions, reveal some similarities and differences of their characteristics and prove the importance of the constructive role of utterance as a minimal unit of speech production. Discourse-speech act-utterance correlation supports the utterance role of a discrete unit within syntactic continuum, facing both language and speech: still, it belongs exclusively neither to language nor speech, but specifies their interaction in course of speech activity exposing simultaneously its nature of an ‘atom of discourse’ and creating the definitional domain of a speech act.

In the secondary comparisons involving only short-acting reversible contraception users, the continuation probability was higher in the preference group compared with the randomized group (P = .04). However, the short-acting reversible contraception randomized group and short-acting reversible contraception preference group had statistically equivalent rates of unintended pregnancy (P = .77). Seventy-eight percent of randomized long-acting reversible contraception users were happy/neutral with their initial method, compared with 89% of randomized short-acting reversible contraception users (P 90%). Even in a typical population of women who presented to initiate or continue short-acting reversible contraception, long-acting reversible contraception proved highly acceptable. One year after initiation, women randomized to long-acting reversible contraception had high continuation rates and consequently experienced superior protection from unintended pregnancy compared with women using short-acting reversible contraception; these findings are attributable to the initial technology and not underlying factors that often bias observational estimates of effectiveness. The similarly patterned experiences of the 2 short-acting reversible contraception cohorts provide a bridge of generalizability between the randomized group and usual-care preference group. Benefits of increased voluntary uptake of long-acting

Group theories: relevance to group safety studies.
Benevento, A L
1998-01-01
Promoting safety in the workplace has been attempted in a variety of ways. Increasingly, industries are using groups such as safety teams and quality circles to promote worker safety. Group influences on individual behavior and attitudes have long been studied in the social psychology literature, but the theories have not been commonly found outside the psychology arena. This paper describes the group theories of group polarization, risky shift, social loafing, groupthink and team think and attempts to apply these theories to existing studies that examine work group influences on safety. Interesting parallels were found but only one study examined group influences as their primary focus of research. Since groups are increasingly used for safety promotion, future research on safety that studies group influences with respect to current group theories is recommended.

We investigate the existence of black hole and soliton solutions to four dimensional, anti-de Sitter (adS), Einstein-Yang-Mills theories with general semisimple connected and simply connected gauge groups, concentrating on the so-called "regular" case. We here generalise results for the asymptotically flat case, and compare our system with similar results from the well-researched adS $\\mathfrak{su}(N)$ system. We find the analysis differs from the asymptotically flat case in some important ways: the biggest difference is that for $\\Lambda<0$, solutions are much less constrained as $r\\rightarrow\\infty$, making it possible to prove the existence of global solutions to the field equations in some neighbourhood of existing trivial solutions, and in the limit of $|\\Lambda|\\rightarrow\\infty$. In particular, we can identify non-trivial solutions where the gauge field functions have no zeroes, which in the $\\mathfrak{su}(N)$ case proved important to stability.

Full Text Available This paper intends to describe the range of forms women’s resistance to globalisation takes, emphasising diverse strategies from everyday acts, the development of practical alternative resources, organising in women’s groups or trades unions, mass demonstrations and symbolic defiance. Recognising that it is the women of the South, in particular, who bear the brunt of the impact of neoliberal ‘free market’ economic policies, it hoped to be sensitive to the struggles for survival that might frame the urgency of resistance amongst women of the South, and make links with some of the strategies of activist women in the more privileged North.

Identifying methods to increase cooperation and efficiency in public goods provision is of vital interest for human societies. The methods that have been proposed often incur costs that (more than) destroy the efficiency gains through increased cooperation. It has for example been shown that inter-group conflict increases intra-group cooperation, however at the cost of collective efficiency. We propose a new method that makes use of the positive effects associated with inter-group competition but avoids the detrimental (cost) effects of a structural conflict. We show that the mere comparison to another structurally independent group increases both the level of intra-group cooperation and overall efficiency. The advantage of this new method is that it directly transfers the benefits from increased cooperation into increased efficiency. In repeated public goods provision we experimentally manipulated the participants' level of contribution feedback (intra-group only vs. both intra- and inter-group) as well as the provision environment (smaller groups with higher individual benefits from cooperation vs. larger groups with lower individual benefits from cooperation). Irrespective of the provision environment groups with an inter-group comparison opportunity exhibited a significantly stronger cooperation than groups without this opportunity. Participants conditionally cooperated within their group and additionally acted to advance their group to not fall behind the other group. The individual efforts to advance the own group cushion the downward trend in the above average contributors and thus render contributions on a higher level. We discuss areas of practical application.

To examine the effects of a 1-day acceptance and commitment therapy (ACT) workshop on the mental health of clinically distressed health care employees, and to explore ACT's processes of change in a routine practice setting. A quasi-controlled design, with participants block allocated to an ACT intervention or waiting list control group based on self-referral date. Participants were 35 health care workers who had self-referred for the ACT workshop via a clinical support service for staff. Measures were completed by ACT and control group participants at pre-intervention and 3 months post-intervention. Participants allocated to the waitlist condition went on to receive the ACT intervention and were also assessed 3 months later. At 3 months post-intervention, participants in the ACT group reported a significantly lower level of psychological distress compared to the control group (d = 1.41). Across the 3-month evaluation period, clinically significant change was exhibited by 50% of ACT participants, compared to 0% in the control group. When the control group received the same ACT intervention, 69% went on to exhibit clinically significant change. The ACT intervention also resulted in significant improvements in psychological flexibility, defusion, and mindfulness skills, but did not significantly reduce the frequency of negative cognitions. Bootstrapped mediation analyses indicated that the reduction in distress in the ACT condition was primarily associated with an increase in mindfulness skills, especially observing and non-reactivity. These findings provide preliminary support for providing brief ACT interventions as part of routine clinical support services for distressed workers. A 1-day ACT workshop delivered in the context of a routine staff support service was effective for reducing psychological distress among health care workers. The brief nature of this group intervention means it may be particularly suitable for staff support and primary care mental

Mixed Waste Working Group report
Energy Technology Data Exchange (ETDEWEB)
1993-11-09
The treatment of mixed waste remains one of this country`s most vexing environmental problems. Mixed waste is the combination of radioactive waste and hazardous waste, as defined by the Resource Conservation and Recovery Act (RCRA). The Department of Energy (DOE), as the country`s largest mixed waste generator, responsible for 95 percent of the Nation`s mixed waste volume, is now required to address a strict set of milestones under the Federal Facility Compliance Act of 1992. DOE`s earlier failure to adequately address the storage and treatment issues associated with mixed waste has led to a significant backlog of temporarily stored waste, significant quantities of buried waste, limited permanent disposal options, and inadequate treatment solutions. Between May and November of 1993, the Mixed Waste Working Group brought together stakeholders from around the Nation. Scientists, citizens, entrepreneurs, and bureaucrats convened in a series of forums to chart a course for accelerated testing of innovative mixed waste technologies. For the first time, a wide range of stakeholders were asked to examine new technologies that, if given the chance to be tested and evaluated, offer the prospect for better, safer, cheaper, and faster solutions to the mixed waste problem. In a matter of months, the Working Group has managed to bridge a gap between science and perception, engineer and citizen, and has developed a shared program for testing new technologies.
Introduction to Sporadic Groups

Luis J. Boya
2011-01-01
Full Text Available This is an introduction to finite simple groups, in particular sporadic groups, intended for physicists. After a short review of group theory, we enumerate the 1+1+16=18 families of finite simple groups, as an introduction to the sporadic groups. These are described next, in three levels of increasing complexity, plus the six isolated ''pariah'' groups. The (old five Mathieu groups make up the first, smallest order level. The seven groups related to the Leech lattice, including the three Conway groups, constitute the second level. The third and highest level contains the Monster group M, plus seven other related groups. Next a brief mention is made of the remaining six pariah groups, thus completing the 5+7+8+6=26 sporadic groups. The review ends up with a brief discussion of a few of physical applications of finite groups in physics, including a couple of recent examples which use sporadic groups.

Full Text Available This essay attempts to take up the challenge of the human subject’s understanding in light of contemporary ›systemic‹ superstructures and above all the achievements of Artificial Intelligence. For the construction of a respective theory of human understanding, a number of significant impetuses arise as soon as the argument regarding the conditio humana – in contrast to the one-sided conception of man as an actively interpreting subject – takes into account the fundamental passivity of its condition, as well as its need for comprehensibility. The theory has to consider how the understanding of being a subject develops in acts of comprehension, i.e. the ›self‹ as a secondary formation. (The essay outlines parts of such a theory referencing H. Plessner.The fruitful consequences of such an undertaking are situated in three areas: (1 The complex processes of construction in all modes of understanding. (2 The imposition or demand to understand (versus a complete moralization, i.e. ›understanding‹ as a bestowed kindness or as pertaining to the extend of one’s character. (3 The primordial situation for human beings is that there are already interpretations and ascriptions; from that results the structural susceptibility to ideology within the hermeneutical process (the homo interpretativus is at once the homo ideologicus. To this ideology which masks the real interrelations belongs essentially the ideology of hermeneutical concepts and metaphors themselves which circulatein our times in everyday speech. Considering these three areas, also helps to escape a new fundamentalism which certain hermeneutical modes of thinking harbour within themselves (›anthropologoumena‹ in place of a necessary social theory.

The NASA Advanced Communications Technology Satellite (ACTS) was conceived to help maintain U.S. leadership in the world's communications-satellite market. This experimental satellite is expected to be launched by NASA in 1992 and to furnish the technology necessary for establishing very small aperture terminal digital networks which provide on-demand full-mesh connectivity, and 1.544-MBPS services with only a single hop. Utilizing on-board switching and processing, each individual voice or data circuit can be separately routed to any location in the network. This paper provides an overview of the ACTS and discusses the value of the technology for future communications systems.

We show that through appropriate contractions the solutions found in the $G_2$-heterotic case converge to the heterotic solutions on 6-dimensional inner non-K\\"ahler spaces previously found by the authors and, moreover, to new heterotic solutions with non-constant dilaton in dimension 5. All solutions satisfy the heterotic equations of motion up to the first order of $\\alpha^{\\prime}$.

We carry out a Lie group analysis of the Sachs equations for a time-dependent axisymmetric non-rotating spacetime in which the Ricci tensor vanishes. These equations, which are the first two members of the set of Newman-Penrose equations, define the characteristic initial-value problem for the spacetime. We find that the equations admit a five-dimensional equivalence Lie algebra. The initial value function that allows the equations to admit a non-trivial Lie symmetry separates into three disjoint equivalence classes.

Full Text Available Since 2001 and 7/7 the search to find out why and how Muslims born in Europe join political and violence orientated Islamist groups has occupied policy makers and social scientist. The search has produced explanations that suggest social grievance, Islam and physiological problems are the motivations for why some Muslims join and act on behalf of Islamist groups in the UK. However, the approaches tend not to focus the role emotions generated from events that involve Muslim suffering play in some individuals becoming interested in acquiring and acting upon them. These events are often experienced variously by Muslims living in Europe through the media and are used by Islamist groups as resources to recruit. Consequently, this paper is based on interviews carried out with Islamists in the UK and tentatively discusses two process that take into account the emotional effect of events that concern Muslims in order to make sense of how some Muslims become compelled to acquire extreme ideas, act upon extreme ideas (independently or behalf of a group or join Islamist groups.

2013-01-01
Full Text Available BACKGROUND: The text deals with terminology issues from an interdisciplinary point of view. It is based on two diﬀerent disciplines, law and kinanthropology, in an area of their overlap. AIM: The aim of the author is to point out some possible legislative problems, which could arise due to the current reading of the sport supporting act (Act no. 115/2001. The second aim of the author is to contribute to the discussion of kinantropologists (possibly also the educational researchers and lawyers and to stress the importance of the systematic approach to terminology formulation. METHODS: The author uses the method of language interpretation. We also use the basic analytical methods, induction and deduction, while we stress the systematic approach to the term formulation. RESULTS: The analysis of the sport supporting act terminology shows some specific legislative problems, which could arise due to the definition of sport in the sport supporting act. The author discusses a possible alternative solution. CONCLUSION: According to the opinion of the author, clear, obvious and unified terminology of kinantropologists as specialists in their discipline should represent a source, from which other sciences could derive their terminology. Defined and inexpert terminology used in other disciplines should not be used as an argument for its adopting in kinanthropology.

Stress and nurses' horizontal mobbing: moderating effects of group identity and group support.
Topa, Gabriela; Moriano, Juan A
2013-01-01
Horizontal mobbing is a process of systematic and repeated aggression towards a worker by coworkers. Among others, stress has been pointed out as one of the antecedents that favors the onset of horizontal mobbing, whereas group support to the target could act as a buffer. Moreover, the social identity approach emphasizes that group identity is an antecedent of group support. This study explores the interaction of group support and group identity in the explanation of horizontal mobbing in a sample (N = 388) of registered nurses and licensed practical nurses employed at two large hospitals in Madrid and Navarre (Spain). The results show that stress is positively associated to horizontal mobbing, whereas group support and group identity were negative predictors of horizontal mobbing. Furthermore, the combination of low group identity and low group support precipitated HM among nurses.
Match statistics related to winning in the group stage of 2014 Brazil FIFA World Cup.

Identifying match statistics that strongly contribute to winning in football matches is a very important step towards a more predictive and prescriptive performance analysis. The current study aimed to determine relationships between 24 match statistics and the match outcome (win, loss and draw) in all games and close games of the group stage of FIFA World Cup (2014, Brazil) by employing the generalised linear model. The cumulative logistic regression was run in the model taking the value of each match statistic as independent variable to predict the logarithm of the odds of winning. Relationships were assessed as effects of a two-standard-deviation increase in the value of each variable on the change in the probability of a team winning a match. Non-clinical magnitude-based inferences were employed and were evaluated by using the smallest worthwhile change. Results showed that for all the games, nine match statistics had clearly positive effects on the probability of winning (Shot, Shot on Target, Shot from Counter Attack, Shot from Inside Area, Ball Possession, Short Pass, Average Pass Streak, Aerial Advantage and Tackle), four had clearly negative effects (Shot Blocked, Cross, Dribble and Red Card), other 12 statistics had either trivial or unclear effects. While for the close games, the effects of Aerial Advantage and Yellow Card turned to trivial and clearly negative, respectively. Information from the tactical modelling can provide a more thorough and objective match understanding to coaches and performance analysts for evaluating post-match performances and for scouting upcoming oppositions.

Point groups in the Vibron model
Energy Technology Data Exchange (ETDEWEB)
Leviatan, A.
1989-08-01
The question of incorporating the notion of point groups in the algebraic Vibron model for molecular rotation--vibration spectra is addressed. Boson transformations which act on intrinsic states are identified as the algebraic analog of the discrete point group transformations. A prescription for assigning point group labels to states of the Vibron model is obtained. In case of nonlinear triatomic molecules the Jacobi coordinates are found to be a convenient possible choice for the geometric counterparts of the algebraic shape parameters. The work focuses on rigid diatomic and triatomic molecules (linear and bent).

Ordered groups and infinite permutation groups
1996-01-01
The subjects of ordered groups and of infinite permutation groups have long en joyed a symbiotic relationship. Although the two subjects come from very different sources, they have in certain ways come together, and each has derived considerable benefit from the other. My own personal contact with this interaction began in 1961. I had done Ph. D. work on sequence convergence in totally ordered groups under the direction of Paul Conrad. In the process, I had encountered "pseudo-convergent" sequences in an ordered group G, which are like Cauchy sequences, except that the differences be tween terms of large index approach not 0 but a convex subgroup G of G. If G is normal, then such sequences are conveniently described as Cauchy sequences in the quotient ordered group GIG. If G is not normal, of course GIG has no group structure, though it is still a totally ordered set. The best that can be said is that the elements of G permute GIG in an order-preserving fashion. In independent investigations around that t...
Isometry groups of proper metric spaces
Niemiec, Piotr
2012-01-01
Given a locally compact Polish space X, a necessary and sufficient condition for a group G of homeomorphisms of X to be the full isometry group of (X,d) for some proper metric d on X is given. It is shown that every locally compact Polish group G acts freely on GxY as the full isometry group of GxY with respect to a certain proper metric on GxY, where Y is an arbitrary locally compact Polish space with (card(G),card(Y)) different from (1,2). Locally compact Polish groups which act effectively and almost transitively on complete metric spaces as full isometry groups are characterized. Locally compact Polish non-Abelian groups on which every left invariant metric is automatically right invariant are characterized and fully classified. It is demonstrated that for every locally compact Polish space X having more than two points the set of proper metrics d such that Iso(X,d) = {id} is dense in the space of all proper metrics on X.
Local Groups Online: Political Learning and Participation
Kavanaugh, Andrea; Zin, Thanthan; Schmitz, Joseph; Rosson, Mary Beth; Kim, B. Joon; Carroll, John M.
Voluntary associations serve crucial roles in local communities and within our larger democratic society. They aggregate shared interests, collective will, and cultivate civic competencies that nurture democratic participation. People active in multiple local groups frequently act as opinion leaders and create “weak” social ties across groups. In Blacksburg and surrounding Montgomery County, Virginia, the Blacksburg Electronic Village (BEV) community computer network has helped to foster nearly universal Internet penetration. Set in this dense Internet context, the present study investigated whether and how personal affiliation with local groups enhanced political participation in this high information and communication technology environment. This paper presents findings from longitudinal survey data which indicate that as individuals’ uses of information technology within local formal groups increase over time, so do their levels and types of involvement in the group. Furthermore, these increases most often appear among people who serve as opinion leaders and maintain weak social ties in their communities. Individuals’ changes in community participation, interests and activities, and Internet use suggest ways in which group members act upon political motivations and interests across various group types.

Quantum groups: Geometry and applications
Energy Technology Data Exchange (ETDEWEB)
Chu, C.S. [Lawrence Berkeley Lab., CA (United States). Theoretical Physics Group
1996-05-13
The main theme of this thesis is a study of the geometry of quantum groups and quantum spaces, with the hope that they will be useful for the construction of quantum field theory with quantum group symmetry. The main tool used is the Faddeev-Reshetikhin-Takhtajan description of quantum groups. A few content-rich examples of quantum complex spaces with quantum group symmetry are treated in details. In chapter 1, the author reviews some of the basic concepts and notions for Hopf algebras and other background materials. In chapter 2, he studies the vector fields of quantum groups. A compact realization of these vector fields as pseudodifferential operators acting on the linear quantum spaces is given. In chapter 3, he describes the quantum sphere as a complex quantum manifold by means of a quantum stereographic projection. A covariant calculus is introduced. An interesting property of this calculus is the existence of a one-form realization of the exterior differential operator. The concept of a braided comodule is introduced and a braided algebra of quantum spheres is constructed. In chapter 4, the author considers the more general higher dimensional quantum complex projective spaces and the quantum Grassman manifolds. Differential calculus, integration and braiding can be introduced as in the one dimensional case. Finally, in chapter 5, he studies the framework of quantum principal bundle and construct the q-deformed Dirac monopole as a quantum principal bundle with a quantum sphere as the base and a U(1) with non-commutative calculus as the fiber. The first Chern class can be introduced and integrated to give the monopole charge.

Frobenius groups of automorphisms and their fixed points
Khukhro, Evgenii I; Shumyatsky, Pavel
2010-01-01
Suppose that a finite group $G$ admits a Frobenius group of automorphisms $FH$ with kernel $F$ and complement $H$ such that the fixed-point subgroup of $F$ is trivial: $C_G(F)=1$. In this situation various properties of $G$ are shown to be close to the corresponding properties of $C_G(H)$. By using Clifford's theorem it is proved that the order $|G|$ is bounded in terms of $|H|$ and $|C_G(H)|$, the rank of $G$ is bounded in terms of $|H|$ and the rank of $C_G(H)$, and that $G$ is nilpotent if $C_G(H)$ is nilpotent. Lie ring methods are used for bounding the exponent and the nilpotency class of $G$ in the case of metacyclic $FH$. The exponent of $G$ is bounded in terms of $|FH|$ and the exponent of $C_G(H)$ by using Lazard's Lie algebra associated with the Jennings--Zassenhaus filtration and its connection with powerful subgroups. The nilpotency class of $G$ is bounded in terms of $|H|$ and the nilpotency class of $C_G(H)$ by considering Lie rings with a finite cyclic grading satisfying a certain `selective ni...

Locally minimal topological groups

A Hausdorff topological group $(G,\\tau)$ is called locally minimal if there exists a neighborhood $U$ of 0 in $\\tau$ such that $U$ fails to be a neighborhood of zero in any Hausdorff group topology on $G$ which is strictly coarser than $\\tau.$ Examples of locally minimal groups are all subgroups of Banach-Lie groups, all locally compact groups and all minimal groups. Motivated by the fact that locally compact NSS groups are Lie groups, we study the connection between local minimality and the NSS property, establishing that under certain conditions, locally minimal NSS groups are metrizable. A symmetric subset of an abelian group containing zero is said to be a GTG set if it generates a group topology in an analogous way as convex and symmetric subsets are unit balls for pseudonorms on a vector space. We consider topological groups which have a neighborhood basis at zero consisting of GTG sets. Examples of these locally GTG groups are: locally pseudo--convex spaces, groups uniformly free from small subgroups (...

The forms of the invariant primitive tensors for the simple Lie algebras A{sub l}, B{sub l}, C{sub l} and D{sub l} are investigated. A new family of symmetric invariant tensors is introduced using the non-trivial cocycles for the Lie algebra cohomology. For the A{sub l} algebra it is explicitly shown that the generic forms of these tensors become zero except for the l primitive ones and that they give rise to the l primitive Casimir operators. Some recurrence and duality relations are given for the Lie algebra cocycles. Tables for the 3- and 5-cocycles for su(3) and su(4) are also provided. Finally, new relations involving the d and f su(n) tensors are given. (orig.). 34 refs.

We give a new construction of higher arithmetic Chow groups for quasi-projective arithmetic varieties over a field. Our definition agrees with the higher arithmetic Chow groups defined by Goncharov for projective arithmetic varieties over a field. These groups are the analogue, in the Arakelov context, of the higher algebraic Chow groups defined by Bloch. The degree zero group agrees with the arithmetic Chow groups of Burgos. Our new construction is shown to be a contravariant functor and is endowed with a product structure, which is commutative and associative.

Full Text Available The objective of this article lies in the understanding of the learning process that occurs in cross-functional groups in automotive companies in light of the Transactive Memory System (TMS. The specific objectives describe the working methodology applied for the operation of multifunctional groups and its relation to learning; the main factors that facilitate group learning and the moments which there was evidence of group learning. The research methodology used is qualitative and exploratory approaches due to the fact those approaches has been less explored in the academic environment. Two different organizations were investigated: the first one is a multinational which works with a strategy of offering complete innovation product, and the other with strategy of offering incremental innovative products for the automotive industry. The results indicated that the fact TMS acts as an important facilitator of group learning.

Group signatures try to combine security (no framing, no cheating and privacy(anonymity, unlinkability.A group digital signature is a digital signature with enhanced privacy features that allows members of a given group to anonymously sign messages on behalf of the group, producing a group signature. However, in the case of dispute the identity of the signature's originator can be revealed by a designated entity (group manager. The present paper describes the main concepts about group signatures, along with a brief state of the art and shows a personal cryptographic library implemented in Java that includes two group signatures.

The group Lasso is an extension of the Lasso for feature selection on (predefined) non-overlapping groups of features. The non-overlapping group structure limits its applicability in practice. There have been several recent attempts to study a more general formulation, where groups of features are given, potentially with overlaps between the groups. The resulting optimization is, however, much more challenging to solve due to the group overlaps. In this paper, we consider the efficient optimization of the overlapping group Lasso penalized problem. We reveal several key properties of the proximal operator associated with the overlapping group Lasso, and compute the proximal operator by solving the smooth and convex dual problem, which allows the use of the gradient descent type of algorithms for the optimization. We have performed empirical evaluations using the breast cancer gene expression data set, which consists of 8,141 genes organized into (overlapping) gene sets.

A fast-acting valve actuator utilizes a spring driven pneumatically loaded piston to drive a valve gate. Rapid exhaust of pressurized gas from the pneumatically loaded side of the piston facilitates an extremely rapid piston stroke. A flexible selector diaphragm opens and closes an exhaust port in response to pressure differentials created by energizing and de-energizing a solenoid which controls the pneumatic input to the actuator as well as selectively providing a venting action to one side of the selector diaphragm.
Language change in a multiple group society
Pop, Cristina-Maria; Frey, Erwin
2013-08-01
The processes leading to change in languages are manifold. In order to reduce ambiguity in the transmission of information, agreement on a set of conventions for recurring problems is favored. In addition to that, speakers tend to use particular linguistic variants associated with the social groups they identify with. The influence of other groups propagating across the speech community as new variant forms sustains the competition between linguistic variants. With the utterance selection model, an evolutionary description of language change, Baxter [Phys. Rev. EPLEEE81539-375510.1103/PhysRevE.73.046118 73, 046118 (2006)] have provided a mathematical formulation of the interactions inside a group of speakers, exploring the mechanisms that lead to or inhibit the fixation of linguistic variants. In this paper, we take the utterance selection model one step further by describing a speech community consisting of multiple interacting groups. Tuning the interaction strength between groups allows us to gain deeper understanding about the way in which linguistic variants propagate and how their distribution depends on the group partitioning. Both for the group size and the number of groups we find scaling behaviors with two asymptotic regimes. If groups are strongly connected, the dynamics is that of the standard utterance selection model, whereas if their coupling is weak, the magnitude of the latter along with the system size governs the way consensus is reached. Furthermore, we find that a high influence of the interlocutor on a speaker's utterances can act as a counterweight to group segregation.

Much is still unclear about the effects of diversity, however. We review the 1997-2005 literature on work group diversity to assess the state of the art and to identify key issues for future research. This review points to the need for more complex conceptualizations of diversity, as well as to the need for more empirical attention to the processes that are assumed to underlie the effects of diversity on group process and performance and to the contingency factors of these processes.

Let be a group and $A = \\text{Aut}(G)$ be the group of automorphisms of . Then, the element $[g, ] = g^{-1}(g)$ is an autocommutator of $g \\in G$ and $ \\in A$. Hence, for any natural number the -th autocommutator subgroup of is defined as $K_{m}(G)=\\langle [g,_{1},\\ldots,_{m}]|g\\in G,_{1},\\ldots,_{m}\\in A\\rangle$, where $[g, _{1}, _{2},\\ldots, _{m}] = [[g,_{1},\\ldots,_{m−1}], _{m}]$. In this paper, we introduce the new notion of -nilpotent groups and classify all abelian groups which are -nilpotent groups.

It is proved that there is no chaotic group actions on any topological space with free arc.In this paper the chaotic actions of the group like G×F,where F is a finite group,are studied.In particular,under a suitable assumption ,if F is a cyclic group,then the topological space which admits a chaotic action of Z×F must admit a chatotic homeomorphism.A topological space which admits a chaotic group action but admits no chaotic horneomorphism is constructed.

Robert Steinberg's Lectures on Chevalley Groups were delivered and written during the author's sabbatical visit to Yale University in the 1967-1968 academic year. The work presents the status of the theory of Chevalley groups as it was in the mid-1960s. Much of this material was instrumental in many areas of mathematics, in particular in the theory of algebraic groups and in the subsequent classification of finite groups. This posthumous edition incorporates additions and corrections prepared by the author during his retirement, including a new introductory chapter. A bibliography and editorial notes have also been added. This is a great unsurpassed introduction to the subject of Chevalley groups that influenced generations of mathematicians. I would recommend it to anybody whose interests include group theory. -Efim Zelmanov, University of California, San Diego Robert Steinberg's lectures on Chevalley groups were given at Yale University in 1967.

Pharmaceuticals and antibiotics co-occur in the aquatic environment but mixture studies to date have mainly focused on pharmaceuticals alone or antibiotics alone, although differences in mode of action may lead to different effects in mixtures. In this study we used the Bacterial Luminescence Toxicity Screen (BLT-Screen) after acute (0.5 h) and chronic (16 h) exposure to evaluate how non-specifically acting pharmaceuticals and specifically acting antibiotics act together in mixtures. Three models were applied to predict mixture toxicity including concentration addition, independent action and the two-step prediction (TSP) model, which groups similarly acting chemicals together using concentration addition, followed by independent action to combine the two groups. All non-antibiotic pharmaceuticals had similar EC50 values at both 0.5 and 16 h, indicating together with a QSAR (Quantitative Structure-Activity Relationship) analysis that they act as baseline toxicants. In contrast, the antibiotics' EC50 values decreased by up to three orders of magnitude after 16 h, which can be explained by their specific effect on bacteria. Equipotent mixtures of non-antibiotic pharmaceuticals only, antibiotics only and both non-antibiotic pharmaceuticals and antibiotics were prepared based on the single chemical results. The mixture toxicity models were all in close agreement with the experimental results, with predicted EC50 values within a factor of two of the experimental results. This suggests that concentration addition can be applied to bacterial assays to model the mixture effects of environmental samples containing both specifically and non-specifically acting chemicals.

In 1989, Malaysia amended its penal code to provide that inducing an abortion is not an offense if the procedure is performed by a registered medical practitioner who has determined that continuation of the pregnancy would risk the life of the woman or damage her mental or physical health. Additional amendments include a legal description of the conditions which constitute the act of rape. Among these conditions is intercourse with or without consent with a woman under the age of 16. Malaysia fails to recognize rape within a marriage unless the woman is protected from her husband by judicial decree or is living separately from her husband according to Muslim custom. Rape is punishable by imprisonment for a term of 5-20 years and by whipping.

This article describes the history and the prevailing orientations of group psychotherapy in Italy (psychoanalytically oriented, psychodrama, CBT groups) and particularly group analysis. Provided free of charge by the Italian health system, group psychotherapy is growing, but its expansion is patchy. The main pathways of Italian training in the different group psychotherapy orientations are also presented. Clinical-theoretical elaboration on self development, psychopathology related to group experiences, and the methodological attention paid to objectives and methods in different clinical groups are issues related to group therapy in Italy. Difficulties in the relationship between research and clinical practice are discussed, as well as the empirical research network that tries to bridge the gap between research and clinical work in group psychotherapy. The economic crisis in Italy has led to massive cuts in health care and to an increasing demand for some forms of psychological treatment. For these reasons, and because of its positive cost-benefit ratio, group psychotherapy is now considered an important tool in the national health care system to expand the clinical response to different forms of psychological distress.
Renormalization group approach to a p-wave superconducting model

We present in this work an exact renormalization group (RG) treatment of a one-dimensional p-wave superconductor. The model proposed by Kitaev consists of a chain of spinless fermions with a p-wave gap. It is a paradigmatic model of great actual interest since it presents a weak pairing superconducting phase that has Majorana fermions at the ends of the chain. Those are predicted to be useful for quantum computation. The RG allows to obtain the phase diagram of the model and to study the quantum phase transition from the weak to the strong pairing phase. It yields the attractors of these phases and the critical exponents of the weak to strong pairing transition. We show that the weak pairing phase of the model is governed by a chaotic attractor being non-trivial from both its topological and RG properties. In the strong pairing phase the RG flow is towards a conventional strong coupling fixed point. Finally, we propose an alternative way for obtaining p-wave superconductivity in a one-dimensional system without spin–orbit interaction.

Full Text Available International Society of Blood Transfusion has recently recognized 33 blood group systems. Apart from ABO and Rhesus system, many other types of antigens have been noticed on the red cell membranes. Blood grouping and cross-matching is one of the few important tests that the anaesthesiologist orders during perioperative period. Hence, a proper understanding of the blood group system, their clinical significance, typing and cross-matching tests, and current perspective are of paramount importance to prevent transfusion-related complications. Nonetheless, the knowledge on blood group system is necessary to approach blood group-linked diseases which are still at the stage of research. This review addresses all these aspects of the blood groups system.
Stochastic Lie group integrators
Malham, Simon J A
2007-01-01
We present Lie group integrators for nonlinear stochastic differential equations with non-commutative vector fields whose solution evolves on a smooth finite dimensional manifold. Given a Lie group action that generates transport along the manifold, we pull back the stochastic flow on the manifold to the Lie group via the action, and subsequently pull back the flow to the corresponding Lie algebra via the exponential map. We construct an approximation to the stochastic flow in the Lie algebra via closed operations and then push back to the Lie group and then to the manifold, thus ensuring our approximation lies in the manifold. We call such schemes stochastic Munthe-Kaas methods after their deterministic counterparts. We also present stochastic Lie group integration schemes based on Castell--Gaines methods. These involve using an underlying ordinary differential integrator to approximate the flow generated by a truncated stochastic exponential Lie series. They become stochastic Lie group integrator schemes if...
