description: It is shown that the matrix models which give non-perturbative definitions of string and M theory may be interpreted as non-local hidden variables theories in which the quantum observables are the eigenvalues of the matrices while their entries are the non-local hidden variables. This is shown by studying the bosonic matrix model at finite temperature, with T taken to scale as 1/N. For large N the eigenvalues of the matrices undergo Brownian motion due to the interaction of the diagonal elements with the off diagonal elements, giving rise to a diffusion constant that remains finite as N goes to infinity. The resulting probability density and current for the eigenvalues are then found to evolve in agreement with the Schroedinger equation, to leading order in 1/N. The quantum fluctuations and uncertainties in the eigenvalues are then consequences of ordinary statistical fluctuations in the values of the off-diagonal matrix elements. This formulation of the quantum theory is background independent, as the definition of the thermal ensemble makes no use of a particular classical solution. The derivation relies on Nelson's stochastic formulation of quantum theory, which is expressed in terms of a variational principle.

Measuring languageness: Fact-checking and debunking a few common myths
Creators: name: Tosco, Mauro
Publisher: name: DIVE-IN – An International Journal on Diversity and Inclusion
Year: 2021

description: The article critically discusses a few common objections to an intrinsic, language-internal definition of what constitutes a ‘language’ (and, conversely, a ‘dialect’). It argues that, contra postmodernism (1.), languages do exist, they can be counted and languageness can be measured independently and even notwithstanding the speakers’ beliefs and ideologies (2.). It further refutes as unsound all the common criticisms to intelligibility as a tool in assessing languageness: while deviations from common-sense assessments may be expected but are not really of concern to science (3.1.), intelligibility asymmetries (3.2.), apparent infinite graduality (3.3.) and dialect chains (3.4.) are only partial problems to be solved empirically. On the contrary, intelligibility can and is routinely measured in different sciences, and, when applied to language, it tends to dovetail with other criteria, such as dialectometry and the counting of isoglosses (4.).

description: We study the statistics and characteristics of rare intense events in two types of two dimensional Complex Ginzburg-Landau (CGL) equation based models. Our numerical simulations show finite amplitude collapse-like solutions which approach the infinite amplitude solutions of the nonlinear Schrödinger (NLS) equation in an appropriate parameter regime. We also determine the probability distribution function (PDF) of the amplitude of the CGL solutions, which is found to be approximately described by a stretched exponential distribution, $P(|A|) \approx e^{-|A|^η}$, where $η< 1$. This non-Gaussian PDF is explained by the nonlinear characteristics of individual bursts combined with the statistics of bursts. Our results suggest a general picture in which an incoherent background of weakly interacting waves, occasionally, `by chance', initiates intense, coherent, self-reinforcing, highly nonlinear events.

description: Among energy supply resources, crude oil has special importance as it supplies more than half of the world energy demands, today. In oil trade, transportation costs have significant effect on ultimate price like other commodities; therefore trade partners often try to select the nearest demand and supply resources. In the research reported herein, global oil trade flows were investigated during 2003 and role of distance as a transportation factor, in trade distribution was appraised. Accessible and relevant oil trade data for 115 countries were gathered. The study database consisted of 20 variables in four categories of trade, geographical, economical and political. Firstly, preliminary statistical analyses of the database were performed. Compared to other variables, country distances and gross domestic product showed higher correlation with national oil trade variables. Furthermore, simple modeling demonstrated that models in form of power had the best fit between oil trade variables, as dependent variables, and the others as independent variables. Moreover, multivariable oil trade models were developed and evaluated. Country distance, which is a geographic variable, was found as a significant decreasing factor in global oil trade. Gravity models for global oil trade were found as good descriptive models. The key variables of the models were gross domestic product of exporters and importers, and country distances which had positive and negative effect on growth of international trade. Finally, linear programming optimized oil trade and the results were compared with observed distribution. Comparison of observed and optimized distribution for the sea network showed possibility of improvements up to one third in total transportation cost.
Language reform, social imaginaries, interlocutor reference

Year: 2021

description: Ludwig Wittgenstein wrote that “to imagine a language means to imagine a form of life.” Here I suggest that the inverse is also true: to imagine a form of life involves imagining a language, or at least, a way of speaking. More specifically, I argue that those who imagine an alternative way life very often target the practices of interlocutor reference (reference to speaker and addressee of an utterance) for reform, apparently seeing such practices as in various ways constitutive of their social existence, including their relations with others. I discuss some of the ways in which thinking about language is constrained and shaped by the very character of language itself. I then turn to consider two cases in which advocates for social change sought to bring about a hoped-for future through reform of the practices of interlocutor reference.

description: Background to the PACE study

The PACE (Primary Assessment, Curriculum and Experience) project aimed to study the impact on English primary schools of the introduction, following the 1988 Education Reform Act, of the National Curriculum and its associated assessment procedures. Questionnaires and interviews with heads and infant teachers in forty-eight schools in eight varied areas, provided background data for a closer focus on nine schools. Children as well as teachers in primary school classes were interviewed. These randomly selected pupils formed a cohort who have taken part in the subsequent years of the study. New assessment procedures were also observed and analysed as they were introduced.

The project consisted of three phases: phase 1 (SN:3486) was carried out in 1990-1992, phase 2 (SN:3470) in 1993-1994 and phase 3(SN:3969) in 1995-1996.

Pupils of the original cohort, continued to be observed and interviewed, as did their teachers into year 6 (phase 3). In addition, teachers and heads in the wider sample of schools have again been interviewed; in this phase both Key Stage 1 and Key Stage 2 teachers provide material on the degree and kind of change experienced in primary schools during a period of unprecedented innovation.

 Phase One of the PACE Study (PACE 1)

This dataset consists of six files:

PACE Advance Questionnaire to Teachers and Headteachers 1990 (TQ01/1TQUEST)

PACE Headteacher Interviews 1990 (2HT INT 90)

PACE Reception and Year 1 Teacher Interviews 1990 (2T INT 90)

PACE Advance Questionnaire to Teachers and Headteachers 1992 (TQ06/6TQUEST)

PACE Headteacher Interviews 1992 (6HT INT 92)

PACE Year 1 and Year 2 Teacher Interviews 1992 (6T INT 92)

The aims of the survey are:

To analyse the responses of heads, teachers and children in infant schools to the National Curriculum and its assessment procedures

To examine the impact of the National Curriculum and its assessment procedures on the curriculum and pedagogy of the infant school

To evaluate the assessment procedures and the materials in use and to examine their effect on children

To develop an innovative `federated research' methodology, whereby the large-scale core project will provide a focus and context for smaller-scale studies, including teachers' action research

To provide a basis for a projected continuing study of the National Curriculum at junior school level.

description: Diese Arbeit untersucht anhand aktueller Literatur die Fähigkeit von Animationsfilmen, Emotionen und Empathie zu erzeugen und verständlich zu machen. Des Weiteren werden darausfolgende pädagogische Potenziale beleuchtet. Durch den gezielten Einsatz filmischer Mittel und den hohen Grad an Gestaltungsfreiheit können Animationsfilme nicht nur Emotionen und Empathie auslösen, sondern diese Reaktionen auch bewusst verstärken. Besonders die intensivierten und vereinfachten Designs der Animationsfiguren und Gesichter macht das Aufbringen von Empathie für diese leichter. Zusätzlich können visuelle Metaphern und Symbolfiguren abstrakte emotionale Konzepte veranschaulichen. Erlangtes Emotionswissen und -vokabular sowie empathisches Wissen kann bei Rezipienten auch zu Lernund Transfereffekten in deren Alltag führen. Die Arbeit zeigt, dass Animationsfilme bedeutendes Potenzial für die pädagogische Vermittlung von emotionalem und empathischem Wissen bieten, das sich allerdings nur in einem pädagogischen Kontext entfalten kann.

Dialoguing with Diversity: Towards an inclusive and egalitarian society

Publisher: name: DIVE-IN – An International Journal on Diversity and Inclusion
Year: 2021

description: ‘Diversity and inclusion’ has been widely recognized as a key principle to be promoted by institutions, corporations and administrations across the world. Yet actual promotion of diversity does not necessarily enhance egalitarian inclusion of marginalized people. It might operate to manage and/or tame differences in society and foster particular kinds of diversity—business-centered, expedient and pleasurable ones—while suppressing others. Through critical appraisal of the discourse and practice of the promotion of diversity, this paper will discuss several ways in which the apparent embracement of diversity deters the advancement of the tackling of lingering inequality and marginalization with some attention to the Japanese situation. Such critique does not negate the significance of diversity and inclusion, but on-going critical dialogue with diversity is indispensable to positively and productively advance and implement the inclusion of diversity towards the construction of egalitarian inclusive society.

description: Transit managers continue to strive for greater operating efficiency while maintaining an appropriate balance between cost effectiveness and customer service. Over the past decade, the use of heavy-duty buses smaller than the traditional forty-foot variety has expanded for several reasons. In some cases, smaller buses are perceived to cost less to acquire, maintain, and operate. Smaller buses may also be required to accommodate route maneuverability constraints, residential and commercial growth patterns, and off-peak empty bus syndrome. However, the availability of prior studies that considered the effectiveness of small buses has been limited. The objective of this research project was to develop a decision support tool to assist transit agencies with evaluating heavy-duty bus fleets and making vehicle acquisition and deployment choices. The product of this effort, the Bus Size Evaluation Tool (BSeT), is a user-friendly and easily-modifiable computer application designed within Microsoft Excel. Building off prior studies and earlier investigations that laid the groundwork for this research, BSeT was designed around a life-cycle cost calculator and a template of weighted factors to help transit agencies select buses that are best suited to satisfy their service obligations. The following research paper describes the research effort, details the process of developing the decision support tool, and offers guidelines for utilizing BSeT. It is important to note that the outcome of this project is not intended as a fleet optimization tool.

description: This paper proposes practical Demand Responsive Transit (DRT) system with a new reservation processing called “Insured Announced Time Reservation System (IATRS)”. DRT service has been expected as an alternative mode in public transportation which aims to improve mobility in a city. However, it was initially impractical because the routing system cannot assure reserved passengers that vehicles will arrive at the passengers’ destination by the announced arrival time. The developed IATRS for this new DRT service intends to ensure the announced arrival time by employing a slack time variable and a new proposed algorithm. The program composes of vehicle-choosing and routing algorithms. The vehicle-choosing algorithm decides which vehicle will accept the new reservation, while the routing algorithm designs the new route and schedule for the vehicle chosen to serve the new reservation. The system calculates and updates the route of the vehicle and returns the pick-up time to the customers immediately during reservation. Moreover, the vehicle will not delay the announced arrival time of passengers who have reserved already even if new passengers are added and the schedule of the vehicle is updated. In order to validate the proposed DRT service, one experiment was conducted in Kashiwa City, Japan in 2008. In the experiment in Kashiwa City, which is recognized as a commuters’ town of Tokyo metropolitan area, 3851 passengers used the about five DRT vehicles in 40 days (480 hours). It was shown that the characteristics of this system worked very well, and more than 44.7 percent of passengers were satisfied with the DRT service because they can make a reservation via personal computers and they were able to specify dependable arrival time or pick-up time. And 36.1 percent of passengers answered that their chances of going out increased by the introduction of DRT service. The result of Willingness To Pay (WTP) analysis is more than twice of fixed bus (353 yen / ride). In conclusion, the result of experiment showed the developed DRT service is a practical alternative mode for public transportation.

description: We have studied the irreversibility of the magnetization induced by thermal cycles in La0.5Ca0.5MnO3 manganites, which present a low temperature state characterized by the coexistence of phases. The effect is evidenced by a decrease of the magnetization after cycling the sample between 300 and 50 K. We developed a phenomenological model that allows us to correlate the value of the magnetization with the number of cycles performed. The experimental results show excellent agreement with our model, suggesting that this material could be used for the development of a device to monitor thermal changes. The effect of thermal cycling is towards an increase of the amount of the non ferromagnetic phase in the compounds and it might be directly related with the strain at the contact surface among the coexisting phases.

description: The Northern Ireland Family Expenditure Survey (NIFES) was conducted in Northern Ireland from 1967-1998, and was the counterpart to the Family Expenditure Survey (FES), which was conducted annually in Great Britain from 1957-2001 (see under GN 33057). The FES/NIFES provided reliable data on expenditure and income in relation to household characteristics. The results of the survey show how expenditure patterns of different kinds of households vary, and the extent to which individual members of a household contribute to the household income. Although originally commissioned to provide expenditure details for the calculation of weights for the Retail Price Index, the FES/NIFES collected much additional information was also collected on the characteristics of co-operating households and the incomes of their members. It thus became a multi-purpose survey, and provided a unique fund of important economic and social data.

From 1968 the Great Britain FES incorporated a sample drawn from the NIFES to become the UK FES. The FES was replaced in 2001 by a new survey series, the Expenditure and Food Survey (EFS) (see under GN 33334), covering the whole of the UK. The EFS is an amalgamation of the previous National Food Survey (NFS) (see under GN 33071) and UK FES.
Natural R-Parity, μ-term, and Fermion Mass Hierarchy From Discrete Gauge Symmetries

description: In the minimal supersymmetric Standard Model with seesaw neutrino masses we show how R-parity can emerge naturally as a discrete gauge symmetry. The same discrete symmetry explains the smallness of the μ-term (the Higgsino mass parameter) via the Giudice--Masiero mechanism. The discrete gauge anomalies are cancelled by a discrete version of the Green--Schwarz mechanism. The simplest symmetry group is found to be Z_4 with a charge assignment that is compatible with grand unification. Several other Z_N gauge symmetries are found for N=10,12,18,36 etc, with some models employing discrete anomaly cancellation at higher Kac-Moody levels. Allowing for a flavor structure in Z_N, we show that the same gauge symmetry can also explain the observed hierarchy in the fermion masses and mixings.

description: We discuss axion dark matter detection via two mechanisms: spontaneous decays and resonant conversion in neutron star magnetospheres. For decays, we show that the brightness temperature signal, rather than flux, is a less ambiguous measure for selecting candidate objects. This is owing principally to the finite beam width of telescopes which prevents one from being sensitive to the total flux from the object. With this in mind, we argue that the large surface-mass-density of the galactic centre or the Virgo cluster centre offers the best chance of improving current constraints on the axion-photon coupling via spontaneous decays. For the neutron star case, we first carry out a detailed study of mixing in magnetised plasmas. We derive transport equations for the axion-photon system via a controlled gradient expansion, allowing us to address inhomogeneous mass-shell constraints for arbitrary momenta. We then derive a non-perturbative Landau-Zener formula for the conversion probability valid across the range of relativistic and non-relativistic axions and show that the standard perturbative resonant conversion amplitude is a truncation of this result in the non-adiabatic limit. Our treatment reveals that that infalling dark matter axions typically convert non-adiabatically in magnetospheres. We describe the limitations of one-dimensional mixing equations and explain how three-dimensional effects activate new photon polarisations, including longitudinal modes and illustrate these arguments with numerical simulations in higher dimensions. We find that the bandwidth of the radio signal is dominated by Doppler broadening from the relative motion of the neutron star with respect to the observer. Therefore, we conclude that the radio signal from the resonant decay is weaker than previously thought, which means one relies on local density peaks to probe weaker axion-photon couplings.

description: A mathematical model and methodology are presented in this paper that can be used to determine the sustainability of a bus service. To formulate the optimization model, an entire bus route in a suburban area is considered on which many eligible stop locations are distributed realistically as discrete points such as intersections or entrances to housing developments. The objective total profit function is maximized by optimizing the number and locations of stops, the headway, and the fare. The number of passengers for the service is dependent on passengers’ access distance, wait time, in-vehicle time, and fare. The solution methodology is applied to an example that uses a bus route in suburban Woodbridge, NJ to demonstrate its effectiveness. The sensitivity of the total profit and of the amount of passengers served to various parameters is analyzed.

description: Secondo i contesti in cui la ‘diversità’ viene collocata, essa assume ruoli e significati differenti: un conto è una diversità di ‘sostanze’, che non hanno nulla in comune (tante sfere incomunicabili), e un altro conto è una diversità di ‘somiglianze’, dove ogni cosa è simile e diversa rispetto a ogni altra cosa (reti di connessioni). Un boschetto in mezzo a palazzi di un quartiere semiperiferico di Torino viene assunto come esemplificazione di un intrico di somiglianze e differenze, il quale sopravvive in mezzo a forme geometriche coesistenti nella loro staticità. Resilienza del divenire rispetto all’essere, delle somiglianze-differenze (SoDif) rispetto all’identità, è il tema su cui l’autore invita a riflettere.

description: The Youth Cohort Study (YCS) is a major programme of longitudinal research designed to monitor the behaviour and decisions of representative samples of young people aged sixteen upwards as they make the transition from compulsory education to further or higher education, or to the labour market. It tries to identify and explain the factors which influence post-16 transitions, for example, educational attainment, training opportunities, experiences at school. To date the YCS covers thirteen cohorts and over forty surveys. The first cohort was first surveyed in 1985 and the thirteenth in 2007. The questionnaires have been designed, over the years, to be broadly comparable, but external changes and shifts in policy interest have brought about changes - some minor, some fundamental. Cohorts One to Twelve cover England and Wales but a change to the methodology means that from Cohort Thirteen, data cover England only. For further details of the methodology and coverage, see the documentation.

The UK Data Archive currently holds data for the cohorts listed below:
Cohort One (SN 3093) surveyed those eligible to leave school in 1983-84

Cohort Two (SN 3094) surveyed those eligible to leave school in 1984-85

*Cohort Three (SN 3012) surveyed those eligible to leave school in 1985-86

Cohort Four (SN 3107) surveyed those eligible to leave school in 1987-88

Cohort Five (SN 3531) surveyed those eligible to leave school in 1989-90

Cohort Six (SN 3532) surveyed those eligible to leave school in 1990-91

Cohort Seven (SN 3533) surveyed those eligible to leave school in 1992-93

Cohort Eight (SN 3805) surveyed those eligible to leave school in 1995-96

Cohort Nine (SN 4009) surveyed those eligible to leave school in 1996-97

Cohort Ten (SN 4571) surveyed those eligible to leave school in 1998-99

Cohort Eleven (SN 5452) surveyed those eligible to leave school in 2000-01

Cohort Twelve (SN 5830) surveyed those eligible to leave school in 2002-03

Cohort Thirteen (SN 6024) surveyed those eligible to leave school in 2005-06

description: We propose that higher-dimensional extended objects (p-branes) are created by super-Planckian scattering processes in theories with TeV scale gravity. As an example, we compute the cross section for p-brane creation in a (n+4)-dimensional spacetime with asymmetric compactification. We find that the cross section for the formation of a brane which is wounded on a compact submanifold of size of the fundamental gravitational scale is larger than the cross section for the creation of a spherically symmetric black hole. Therefore, we predict that branes are more likely to be created than black holes in super-Planckian scattering processes in these manifolds. The higher rate of p-brane production has important phenomenological consequences, as it significantly enhances possible detection of non-perturbative gravitational events in future hadron colliders and cosmic rays detectors.

description: The security of the Internet of Things (IoT) has attracted much attention due to the growing number of IoT-oriented security incidents. IoT hardware and software security vulnerabilities are exploited affecting many companies and persons. Since the causes of vulnerabilities go beyond pure technical measures, there is a pressing demand nowadays to demystify IoT "security complex" and develop practical guidelines for both companies, consumers, and regulators. In this paper, we present an initial study targeting an unexplored sphere in IoT by illuminating the potential of crowdsource ethical hacking approaches for enhancing IoT vulnerability management. We focus on Bug Bounty Programs (BBP) and Responsible Disclosure (RD), which stimulate hackers to report vulnerability in exchange for monetary rewards. We carried out a qualitative investigation supported by literature survey and expert interviews to explore how BBP and RD can facilitate the practice of identifying, classifying, prioritizing, remediating, and mitigating IoT vulnerabilities in an effective and cost-efficient manner. Besides deriving tangible guidelines for IoT stakeholders, our study also sheds light on a systematic integration path to combine BBP and RD with existing security practices (e.g., penetration test) to further boost overall IoT security.

description: The accession to the EU was certainly the most comprehensive change of economic environment since Slovenia gained its independence. Therefore the paper tries to present an overview of the national food industry economic development in the period before the EU accession and the first five years of the EU membership. Based on a framework of economic indicators the paper tries to answer some of the most recurrent questions related to the restructuring process of Slovenian food industry in the last decade. Results confirm that the economic restructuring which had been hindered in the Slovenian food industry during the last decade has been triggered radically after EU accession. This brought to the termination of favourable economic conditions in the highly protected domestic market and deteriorated radically the business performance, and only those food companies which will restructure proactively will sustain in the EU markets.

We call them the finite and infinite Q-systems according to the number of functions and equations. The finite Q-systems appear as the thermal equilibrium conditions (the Sutherland-Wu equation) for certain statistical mechanical systems. Some infinite Q-systems appear as the relations of the normalized characters of the KR modules of the Yangians and the quantum affine algebras. We give two types of power series formulae for the unique solution (resp. the unique canonical solution) for a finite (resp. infinite) Q-system. As an application, we reformulate the Kirillov-Reshetikhin conjecture on the multiplicities formula of the KR modules in terms of the canonical solutions of Q-systems.

description: A model for the symmetric coupling of two self-oscillators is presented. The nonlinearities cause the system to vibrate in two modes of different symmetries. The transition between these two regimes of oscillation can occur by two different scenarios. This might model the release of vortices behind circular cylinders with a possible transition from a symmetric to an antisymmetric Benard-von Karman vortex street.

description: The ^18F(p, alpha)^15O reaction is recognized as one of the most important reaction for nova gamma-ray astronomy as it governs the early =< 511 keV emission. However, its rate remains largely uncertain at nova temperatures due to unknown low-energy resonance strengths. In order to better constrain this reaction rate, we have studied the one-nucleon transfer reaction, D(^18F,p alpha)^15N, at the CRC-RIB facility at Louvain La Neuve.

D Meson Production in Neutrino DIS and Polarized Strange Quark Distribution

description: Semi-inclusive $D / \Dbar$ meson productions in neutrino deep inelastic scattering are studied including ${\cal O}(α_s)$ corrections. Supposing a future neutrino factory, cross sections and spin asymmetries in polarized processes are calculated by using various parametrization models of polarized parton distribution functions. We suggest that $\Dbar$ production is promising to directly extract the strange quark distribution.

Quasinormal modes of a massless Dirac field in de Rham-Gabadadze-Tolley massive gravity

description: The quasinormal modes of a massless Dirac field in the de Rham-Gabadadze-Tolley (dRGT) massive gravity theory with asymptotically de Sitter spacetime are investigated using the Wentzel- Kramers-Brillouin (WKB) approximation. The effective potential for the massless Dirac field due to the dRGT black hole is derived. It is found that the shape of the potential depends crucially on the structure of the graviton mass and the behavior of the quasinormal modes is controlled by the graviton mass parameters. Higher potentials give stronger damping of the quasinormal modes. We compare our results to the Schwarzschild-de Sitter case. Our numerical calculations are checked using Pad$\acute{e}$ approximation and found that the quasinormal mode frequencies converge to ones with reasonable accuracy.

description: It is shown that the numbers of off-diagonal solutions to the U_q(X^{(r)}_N) Bethe equation at q=0 coincide with the coefficients in the recently introduced canonical power series solution of the Q-system. Conjecturally the canonical solutions are characters of the KR (Kirillov-Reshetikhin) modules. This implies that the numbers of off-diagonal solutions agree with the weight multiplicities, which is interpreted as a formal completeness of the U_q(X^{(r)}_N) Bethe ansatz at q=0.

Compact Groups of Galaxies in Sloan Digital Sky Survey and LAMOST Spectral Survey: I. The Catalogs

description: A compact group (CG) is a kind of special galaxy system where the galaxy members are separated at the distances of the order of galaxy size. The strong interaction between the galaxy members makes CGs ideal labs for studying the environmental effects on galaxy evolution. The traditional photometric selection algorithm biases against the CG candidates at low redshifts, while the spectroscopic identification technique is affected by the spectroscopic incompleteness of sample galaxies and typically biases against the high redshift candidates. In this study, we combine these two methods and select CGs in the main galaxy sample of the Sloan Digital Sky Survey, where we also have taken the advantages of the complementary redshift measurements from the LAMOST spectral and GAMA surveys. We have obtained the largest and most complete CG samples to date. Our samples include 6,144 CGs and 8,022 CG candidates, which are unique in the studies of the nature of the CGs and the evolution of the galaxies inside.

Belinfante Tensors Induced by Matter-Gravity Couplings

description: We show that any generally covariant coupling of matter fields to gravity gives rise to a conserved, on-shell symmetric energy-momentum tensor equivalent to the canonical energy-momentum tensor of the flat-space theory. For matter fields minimally coupled to gravity our algorithm gives the conventional Belinfante tensor. We establish that different matter-gravity couplings give metric energy-momentum tensors differing by identically conserved tensors. We prove that the metric energy-momentum tensor obtained from an arbitrary gravity theory is on-shell equivalent to the canonical energy-momentum tensor of the flat-space theory.

description: Porous silicon layers were embedded with ZnTe using the isothermal close space sublimation technique. The presence of ZnTe was demonstrated using cross-sectional energy dispersive spectroscopy maps. ZnTe embedded samples present intense room temperature photoluminescence along the whole visible range. We ascribe this PL to ZnTe nanocrystals of different sizes grown on the internal pore surface. Such crystals, with different orientations and sizes, were observed in transmission electron microscopy images, while transmission electron diffraction images of the same regions reveal ZnTe characteristic patterns.

description: A class of numerical methods to determine Pollicott-Ruelle resonances in chaotic dynamical systems is proposed. This is achieved by relating some existing procedures which make use of Pade approximants and interpolating exponentials to both the memory function techniques used in the theory of relaxation and the filter diagonalization method used in the harmonic inversion of time correlation functions. This relationship leads to a theoretical framework in which all these methods become equivalent and which allows for new and improved numerical schemes.

System size dependence of strangeness production at 158 AGeV

Subjects: subject: Nuclear Experiment (nucl-ex)

description: Strange particle production in A+A interactions at 158 AGeV is studied by the CERN experiment NA49 as a function of system size and collision geometry. Yields of charged kaons, phi and Lambda are measured and compared to those of pions in central C+C, Si+Si and centrality-selected Pb+Pb reactions. An overall increase of relative strangeness production with the size of the system is observed which does not scale with the number of participants. Arguing that rescattering of secondaries plays a minor role in small systems the observed strangeness enhancement can be related to the space-time density of the primary nucleon-nucleon collisions.

description: We show that the apparently periodic Charap-Duff Yang-Mills `instantons' in time-compactified Euclidean Schwarzschild space are actually time independent. For these solutions, the Yang-Mills potential is constant along the time direction (no barrier) and therefore, there is no tunneling. We also demonstrate that the solutions found to date are three dimensional monopoles and dyons. We conjecture that there are no time-dependent solutions in the Euclidean Schwarzschild background.
