description: Rolling tachyon backgrounds, arising from open strings on unstable branes in bosonic string theory, can be related to a simple statistical mechanical model - Coulomb gas of point charges in two dimensions confined to a circle, the Dyson gas. In this letter we describe a statistical system that is dual to non-BPS branes in superstring theory. We argue that even though the concept of time is absent in the statistical dual sitting at equilibrium, the notion of time can emerge at the large number of particles $N \to \infty$ limit.

description: The European bullhead (Cottus gobio) is a fish species listed in the Annex II of the Habitat Directive of the European Union, but their status and population trends have not been estimated so far. In general, estimations for a larger region are rarely possible, mainly due to lack of data. Here, we use a data set from the Office for Wildlife Management consisting of >1300 surveys from 659 different lakes or river sections across South Tyrol, of which 98 sites have been fished multiple times. 
Across the region that covers 7400 km² of the Central European Alps, most monitored populations (78%) increased in density with an average increase of 7 ±3% per year. The few populations with negative population trends were not geographically clustered. We conclude that bullhead populations have predominantly increased across the province, most probably due to improved water quality and habitat availability over the last few decades and despite the ongoing stocking measures of brown trout throughout the study area.

description: Quantum non-Gaussian states represent an important class of highly non-classical states whose preparation requires quantum operations or measurements beyond the class of Gaussian operations and statistical mixing. Here we derive criteria for certification of quantum non-Gaussianity based on probability of vacuum in the original quantum state and a state transmitted through a lossy channel with transmittance T. We prove that the criteria hold for arbitrary multimode states, which is important for their applicability in experiments with broadband sources and single-photon detectors. Interestingly, our approach allows to detect quantum non-Gaussianity using only one photodetector instead of complex multiplexed photon detection schemes, at the cost of increased experimental time. We also formulate a quantum non-Gaussianity criterion based on the vacuum probability and mean photon number of the state and we show that this criterion is closely related to the criteria based on pair of vacuum probabilities. We illustrate the performance of the obtained criteria on the example of realistic imperfect single-photon states modeled as a mixture of vacuum and single-photon states with background Poissonian noise.

A personality study of successful male and female athletes and professionals

Publisher: name: University of British Columbia

description: The hypotheses that there would be no significant differences between successful male and female individuals in law, medicine and athletics on six selected personality traits and five socio-cultural factors were tested by administering Cattell's 16 PF Form C. and a socio-cultural questionnaire. Cattell's 16 PF data obtained from: twenty-eight male athletes, twenty-nine female athletes, twenty male professionals and twelve female professionals (professionals being lawyers and doctors), was analyzed using a one-way analysis of variance. Results indicated that there were no significant differences among the four groups on the six personality traits examined: emotional stability, assertiveness, conscientiousness, tough-mindedness, self-assuredness and self-sufficiency. A Chi Square statistic was used to analyze the data from the socio-cultural questionnaire. The results indicated that there were no significant differences among the four groups on birth order, family size and culture. Significant differences were observed for athletic experience (p ≤ .00001) and educational experience (p ≤ .008). These differences, however, were anticipated as the criteria for selection of subjects was based on their achievement in athletics and education.

description: We present a detailed analysis of the intergalactic metal-line absorption systems in the archival HST/STIS and FUSE ultraviolet spectra of the low-redshift quasar PKS1302-102 (z_QSO = 0.2784). We supplement the archive data with CLOUDY ionization models and a survey of galaxies in the quasar field. There are 15 strong Lya absorbers with column densities logN_HI > 14. Of these, six are associated with at least CIII 977 absorption (logN(C^++) > 13); this implies a redshift density dN_CIII/dz = 36+13/-9 (68% confidence limits) for the five detections with rest equivalent width W_r > 50 mA. Two systems show OVI 1031,1037 absorption in addition to CIII (logN(O^+5) > 14). One is a partial Lyman limit system (logN_HI = 17) with associated CIII, OVI, and SiIII 1206 absorption. There are three tentative OVI systems that do not have CIII detected. For one OVI doublet with both lines detected at 3 sigma with W_r > 50 mA, dN_OVI/dz = 7+9/-4. We also search for OVI doublets without Lya absorption but identify none. From CLOUDY modeling, these metal-line systems have metallicities spanning the range -4 < [M/H] < -0.3. The two OVI systems with associated CIII absorption cannot be single-phase, collisionally-ionized media based on the relative abundances of the metals and kinematic arguments. From the galaxy survey, we discover that the absorption systems are in a diverse set of galactic environments. Each metal-line system has at least one galaxy within 500 km/s and 600 h^-1 kpc with L > 0.1 L_*.

Halos of Modified Gravity

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We describe how a certain simple modification of general relativity, in which the local cosmological constant is allowed to depend on the space-time curvature, predicts the existence of halos of modified gravity surrounding spherically-symmetric objects. We show that the gravitational mass of an object weighed together with its halo can be much larger than its gravitational mass as seen from inside the halo. This effect could provide an alternative explanation of the dark-matter phenomenon in galaxies. In this case, the local cosmological constant in the solar system must be some six orders of magnitude larger than its cosmic value obtained in the supernovae type Ia experiments. This is well within the current experimental bounds, but may be directly observable in the future high-precision experiments.

description: Context. The molecular composition of interstellar ice mantles is defined by gas-grain processes in molecular clouds, with the main components being $H_2O$, $CO$, and $CO_2$. $CH_3OH$ ice is detected towards the denser regions, where large amounts of $CO$ freeze out and get hydrogenated. Heating from nearby protostars can further change the ice structure and composition. Despite the several observations of icy features towards molecular clouds and along the line of site of protostars, it is not yet clear if interstellar ices are mixed or if they have a layered structure. Aims. We aim to examine the effect of mixed and layered ice growth in ice mantle analogues, with focus on the position and shape of methanol infrared bands, so future observations could shed light on the structure of interstellar ices in different environments. Methods. Mixed and layered ice samples were deposited on a cold substrate kept at T = 10 K using a closed-cycle cryostat placed in a vacuum chamber. The spectroscopic features were analysed by FTIR spectroscopy. Different proportions of the most abundant four molecules in ice mantles, namely $H_2O$, $CO$, $CO_2$, and $CH_3OH$, were investigated, with special attention on the analysis of the $CH_3OH$ bands. Results. We measure changes in the position and shape of the CH and CO stretching bands of $CH_3OH$ depending on the mixed or layered nature of the ice sample. Spectroscopic features of methanol are also found to change due to heating. Conclusions. A layered ice structure best reproduces the $CH_3OH$ band position recently observed towards a pre-stellar core and in star-forming regions. Based on our experimental results, we conclude that observations of $CH_3OH$ ices can provide information about the structure of interstellar ices, and we expect JWST to put stringent constraints on the layered or mixed nature of ices in different interstellar environments.

description: We propose a class of models in which the $η$-problem of supersymmetric hybrid inflation is resolved using a Heisenberg symmetry, where the associated modulus field is stabilized and made heavy with the help of the large vacuum energy during inflation without any fine-tuning. The proposed class of models is well motivated both from string theory considerations, since it includes the commonly encountered case of no-scale supergravity Kaehler potential, and from the perspective of particle physics since a natural candidate for the inflaton in this class of models is the right-handed sneutrino which is massless during the inflationary epoch, and subsequently acquires a large mass at the end of inflation. We study a specific example motivated by sneutrino hybrid inflation with no-scale supergravity in some detail, and show that the spectral index may lie within the latest WMAP range, while the tensor-to-scalar ratio is very small.

MÉTHODOLOGIE : Nous avons effectué notre revue de littérature à l’aide des bases de données Pubmed, Cinhal, Cochrane et Psychinfo. Parmi les 117 articles trouvés, nous en avons sélectionné quatre : une méta-analyse, une revue systématique et méta-analyse, ainsi que deux revues systématiques. Les textes sélectionnés étaient en langue anglaise et datés de 2019 à 2022. Nous avons ensuite analysé et associé les résultats des HUG à ceux obtenus au travers de la revue de littérature. RÉSULTATS : L’utilisation de l’aromathérapie par inhalation ou massage semble montrer son efficacité sur de faibles douleurs et une forte anxiété pour des dilatations inférieures à cinq centimètres et comprises entre huit et dix centimètres. Diverses huiles essentielles semblent adaptées telles que la lavande et la rose principalement, bien que l’orange, la camomille, la menthe poivrée et la sauge aient démontré une action significative. Cette méthode augmente la satisfaction des femmes lors de l’accouchement et semble les aider à surmonter efficacement l’accouchement avec le suivi individualisé de la.le sage-femme. CONCLUSION : L’aromathérapie démontre des résultats encourageants dans la gestion de la douleur et de l’anxiété au cours de la phase de latence. Davantage d’études aux méthodologies plus homogènes permettraient d’émettre des recommandations pour la pratique.

description: In some bicategories, the 1-cells are `morphisms' between the 0-cells, such as functors between categories, but in others they are `objects' over the 0-cells, such as bimodules, spans, distributors, or parametrized spectra. Many bicategorical notions do not work well in these cases, because the `morphisms between 0-cells', such as ring homomorphisms, are missing. We can include them by using a pseudo double category, but usually these morphisms also induce base change functors acting on the 1-cells. We avoid complicated coherence problems by describing base change `nonalgebraically', using categorical fibrations. The resulting `framed bicategories' assemble into 2-categories, with attendant notions of equivalence, adjunction, and so on which are more appropriate for our examples than are the usual bicategorical ones. We then describe two ways to construct framed bicategories. One is an analogue of rings and bimodules which starts from one framed bicategory and builds another. The other starts from a `monoidal fibration', meaning a parametrized family of monoidal categories, and produces an analogue of the framed bicategory of spans. Combining the two, we obtain a construction which includes both enriched and internal categories as special cases.

Electron Heat Flux in the Solar Wind: Generalized Approaches to Fluid Transport with a Variety of Skewed Velocity Distributions

description: In the solar corona and solar wind, electron heat conduction is an important process that transports energy over large distances and helps determine the spatial variation of temperature. High-density regions undergoing rapid particle-particle collisions exhibit a heat flux described well by classical Spitzer-Harm theory. However, much of the heliosphere is closer to a more collisionless state, and there is no standard description of heat conduction for fluid-based (e.g., magnetohydrodynamic) models that applies generally. Some proposed models rely on electron velocity distributions that exhibit negative values of the phase-space density. In this paper, we explore how positive-definite velocity distributions can be used in fluid-based conservation equations for the electron heat flux along magnetic-field lines in the corona and solar wind. We study both analytic forms of skewed distributions (e.g., skew-normal distributions, two-sided bi-Maxwellians, and constant-collision-time electrostatic solutions) and empirical fits to measurements of core, halo, and strahl electrons in interplanetary space. We also present example solutions to a generalized conservation equation for the heat flux in the solar wind, with some limiting cases found to resemble known free-streaming approximations. The resulting values of the electron heat flux vary as a function of radial distance and Knudsen number in ways that resemble observed data. We note that this model does not include the effects of kinetic instabilities (which may impose saturation limits when active), so for now its regime of applicability is limited to collisionless heat-flux evolution away from the known instability boundaries in parameter space.

CANGAROO-III Search for Gamma Rays from SN 1987A and the Surrounding Field

Subjects: subject: Astrophysics (astro-ph)

description: Optical images of SN 1987A show a triple ring structure. The inner (dust) ring has recently increased in brightness and in the number of hot spots suggesting that the supernova shock wave has collided with the dense pre-existing circumstellar medium, a scenario supported by radio and X-ray observations. Such a shocked environment is widely expected to result in the acceleration of charged particles, and the accompanying emission of very high energy gamma-rays. Here, we report the results of observations made in 2004 and 2006 which yield upper limits on the TeV gamma-ray flux, which are compared with a theoretical prediction. In addition, we set upper limits on the TeV flux for four high energy objects which are located within the same field of view of the observation: the super-bubble 30 Dor C, the Crab-like pulsar PSR B0540$-$69, the X-ray binary LMC X-1, and the supernova remnant N157B.

description: We present Spitzer rest-frame mid-infrared spectroscopy of twelve z~2 mm-bright type 1 QSOs, selected from unlensed and lensed QSO samples and covering a range of AGN optical luminosities L_5100=10^45 to 10^47 erg/s. On top of the AGN continuum, we detect PAH emission from luminous star formation in nine objects individually as well as in the composite spectrum for the full sample. PAH luminosity and rest frame far-infrared luminosity correlate and extend the similar correlation for lower luminosity local QSOs. This provides strong evidence for intense star formation in the hosts of these mm-bright QSOs, sometimes exceeding 1000 Msun/yr and dominating their rest frame far-infrared emission. The PAH-based limit on star formation rates is lower for luminous z~2 QSOs that are not preselected for their mm emission. Partly dependent on systematic changes of the AGN dust covering factor and the dust spectral energy distribution of the AGN proper, the spectral energy distributions of mm-faint high-z QSOs may be AGN dominated out to rest frame far-infrared wavelengths. Towards the most luminous high-z QSOs, there is a flattening of the relation between star formation and AGN luminosity that is observed for lower redshift QSOs. No QSO in our sample has a PAH-measured star formation rate in excess of 3000 Msun/yr.

description: The susceptibility of nickel-based superalloys to processing-induced crack formation during laser powder-bed additive manufacturing is studied. Twelve different alloys -- some of existing (heritage) type but also other newly-designed ones -- are considered. A strong inter-dependence of alloy composition and processability is demonstrated. Stereological procedures are developed to enable the two dominant defect types found -- solidification cracks and solid-state ductility dip cracks -- to be distinguished and quantified. Differential scanning calorimetry, creep stress relaxation tests at 1000$^\circ$C and measurements of tensile ductility at 800$^\circ$C are used to interpret the effects of alloy composition. A model for solid-state cracking is proposed, based on an incapacity to relax the thermal stress arising from constrained differential thermal contraction; its development is supported by experimental measurements using a constrained bar cooling test. A modified solidification cracking criterion is proposed based upon solidification range but including also a contribution from the stress relaxation effect. This work provides fundamental insights into the role of composition on the additive manufacturability of these materials.
Ground-dwelling invertebrate communities in mountain grasslands in South Tyrol (Italy): Surveying changes in abundances, diversity, and sex ratio
Creators: name: Steinwandter, Michael

Publisher: name: Zenodo
Year: 2023

description: There are few studies of ground-dwelling invertebrates from alpine grasslands, often with only one or a few samplings per growing season. However, to get a comprehensive picture of the faunal community present, sampling over a full season is required. Here we present data on ground-dwelling macro-invertebrate communities from two differently managed mountain grasslands (i.e., an intensively managed hay meadow and an extensively grazed dry pasture). Both sites were monitored continuously over a full growing season (April to early December) using pitfall traps.
We found considerable differences in abundances of the entire ground-dwelling communities and in Araneae species diversity between the two grassland types, with the pasture having the lower abundances (i.e., activity densities as individuals per sampling day) but higher spider species diversity. We still found clear effects of management, most likely due to differences in habitat structure and presumably also in prey availability. Sex ratios of spiders did not differ much between the grasslands, however, a negative effect of mowing on the abundances of Araneae and adult Coleoptera was found. Management intensity negatively affected invertebrate abundances and species diversity, but not population dynamics.
Assessment and collection of corporate income tax in Quebec, Ontario and Alberta : the problems of an independent approach in a federal jurisdiction
Creators: name: Young, Claire F. L.
Publisher: name: University of British Columbia
Year: 2010

description: Seven provinces in Canada have entered tax collection agreements with the federal government whereby that government collects corporate income tax on their behalf. Quebec, Ontario and Alberta have not entered such agreements and levy and collect corporate income tax pursuant to their own legislation and within their own administrative systems. This thesis will examine the problems resulting from the independent approaches taken by Quebec, Ontario and Alberta, as they affect the corporate taxpayer. The problems fall into three categories. First, provincial adoption of the Income Tax Act (Canada), while assuring some similarity between the federal and provincial systems, can have adverse consequences for the corporate taxpayer. Secondly, differences between the legislation of Canada, Quebec, Ontario and Alberta create inconsistencies that present difficulties for the corporate taxpayer. Thirdly, differences in the administrative systems of the three provinces and the federal government increase the cost to the corporate taxpayer and create compliance problems for it. The thesis concludes that the future of the Canadian corporate income tax system will involve even more provincial independence and, therefore, measures to alleviate some of the problems are discussed. These include a new approach to co-operative federalism, an examination of the efficacy of more provincial autonomy and tax harmonization. This analysis shows that the corporate taxpayer would benefit from more cooperation between the federal and provincial governments together with a degree of harmonization of the tax bases.

description: In this paper we present how Semantic Web Service technology can be used to overcome process and data heterogeneity in a B2B integration scenario. While one partner uses standards like RosettaNet for product purchase and UNIFI ISO 20022 for electronic payments in its message exchange process and message definition, the other one operates on non-standard proprietary solution based on a combination of WSDL and XML Schema. For this scenario we show the benefits of semantic descriptions which are used within the integration process to enable rule- based data and process mediation of services. We illustrate this dynamic integration process on the WSMX - a middleware platform conforming to the principles of a Semantic Service Oriented Architecture.
The subterranean ant Strumigenys argiola (Insecta, Formicidae) newly reported from South Tyrol, Italy

description: Strumigenys argiola (Emery, 1869) is reported for the first time from South Tyrol. Several gynes were captured using pitfall traps and workers were collected with the Berlese method from soil core samples. The records originated from five different sites and we consider the species as likely occurring in a wider area of low altitudes in the Adige/Etsch valley. It is possible that the species has extended its distribution northwards colonizing the region more recently. The fact that the sites of record were all human-made (one river dam, one recently abandoned and one managed vineyard) underlines the potential of this cryptic and subterranean species to colonize also anthropogenically influenced sites.

description: This proceedings paper from 2004 contains figures of discharges in different gap lengths at the same potential that are not available elsewhere. The 2004 abstract: The evolution of streamers is known to depend on gas composition and electrode geometry, on polarity and size of the voltage and also on the electric circuit that produces the high voltage pulse. To characterize the phenomena better and to compare with theory, a new larger experimental setup with vacuum enclosure has been built. We here present first results in this setup on positive streamers in air at fixed voltage and varying electrode distance. While next to the emitting anode tip, a similar number of streamers seems to emerge due to multiple branching, more streamers seem to survive over a fixed distance, when the gap is shorter. When lowering the voltage, streamers branch less at all distances from the anode tip or do not branch at all beyond a certain distance.

description: The catalogue of the vascular plants of South Tyrol: additions and corrections (11)
The ongoing floristic mapping and the constant revision of herbarium specimens result in an increase of new – mainly, but not only, allochthonous – taxa in the flora of South Tyrol, but also make adjustments or corrections of previously published data necessary. In the 11th edition of this series the newly discovered native taxa Carex digitata subsp. pallens and Primula integrifolia are presented, as well as Poa humilis with uncertain indigenous status. 
With regard to allochthonous taxa – among them garden escapes and taxa introduced by different pathways – the following can be added to the flora of South Tyrol, some of which are already considered to be established: Allium neapolitanum, Arbutus unedo, Astilbe ×rosea, Berberis julianae, Bromus riparius, Brunnera macrophylla, Cardamine occulta, Chimonanthus praecox, Cistus eriocephalus, Cotoneaster acutifolius, Datura innoxia, D. wrightii, Dianthus giganteus, Diospyros lotus, Eriobotrya japonica, Euphorbia epithymoides, Gleditsia triacanthos, Glyceria grandis, Guizotia abyssinica, Leucanthemella serotina, Mimulus ringens, Noccaea praecox, Oenothera oehlkersii, Phlox paniculata, Pinus wallichiana, Stachys byzantina, Trifolium resupinatum (s.str.), Tulipa gesneriana.
The following native or archeophytic species could be either reconfirmed or definitely confirmed for the flora of South Tyrol: Arabis auriculata, Asparagus tenuifolius, Bolboschoenus laticarpus, Hieracium zizianum, Ophrys apifera, Ornithogalum divergens, Scandix pecten-veneris, Sorbus aucuparia subsp. glabrata. The same holds for the non-native species Bupleurum gerardi and Poncirus trifoliata. In the case of Legousia hybrida, the previously doubted historical presence could be verified.
Important new distribution data and a new status assessment, respectively, are given for the following species: Bromus diandrus, Carex pseudocyperus, Crepis pulchra, Festuca stenantha, Festuca supina, Festuca trichophylla, Poa glauca, Poa remota, Ranunculus peltatus, and Verbascum crassifolium.

description: Observations of the expansion rate of the universe at late times disagree by a factor of 1.5-2 with the prediction of homogeneous and isotropic models based on ordinary matter and gravity. We discuss how the departure from linearly perturbed homogeneity and isotropy due to structure formation could explain this discrepancy. We evaluate the expansion rate in a dust universe which contains non-linear structures with a statistically homogeneous and isotropic distribution. The expansion rate is found to increase relative to the exactly homogeneous and isotropic case by a factor of 1.1-1.3 at some tens of billion of years. The timescale follows from the cold dark matter transfer function and the amplitude of primordial perturbations without additional free parameters.

Multi-objective Test Case Selection Through Linkage Learning-based Crossover

description: Test Case Selection (TCS) aims to select a subset of the test suite to run for regression testing. The selection is typically based on past coverage and execution cost data. Researchers have successfully used multi-objective evolutionary algorithms (MOEAs), such as NSGA-II and its variants, to solve this problem. These MOEAs use traditional crossover operators to create new candidate solutions through genetic recombination. Recent studies in numerical optimization have shown that better recombinations can be made using machine learning, in particular link-age learning. Inspired by these recent advances in this field, we propose a new variant of NSGA-II, called L2-NSGA, that uses linkage learning to optimize test case selection. In particular, we use an unsupervised clustering algorithm to infer promising patterns among the solutions (subset of test suites). Then, these patterns are used in the next iterations of L2-NSGA to create solutions that preserve these inferred patterns. Our results show that our customizations make NSGA-II more effective for test case selection. The test suite sub-sets generated by L2-NSGA are less expensive and detect more faults than those generated by MOEAs used in the literature for regression testing.

description: In this paper we present a demo implementation of an event driven system, which aims to enable execution of Semantic Web Services. Our demo infrastructure is based on the Web Service Modeling Ontology (WSMO) [Roman et al., 2004]. The implementation follows research carried out by the Web Services Modeling Execution1 working group. WSMX is a Service Oriented Architecture (SOA) and allows an agent acting on behalf of a user to talk to WSMX enabling discovery, selection, mediation and invocation of formally described Web Services to carry out specific client tasks. Through the implementation of WSMX we aim to prove the viability of WSMO and although the first implementation of the system remains incomplete in terms of the required functionality, all components are in place and the system is capable of executing simple scenarios. Through continuous open source development 2 we aim to enhance WSMX with the intended functionality for all defined conceptual components.

Type species
Pseudarietites silesiacus Frech, 1902: 63; by monotypy.
Genus diagnosis
Genus of the subfamily Pseudarietitinae with a circular or depressed whorl profile with raised ventral keel paralleled by two longitudinal grooves. Sculpture with simple ribs.
Genus composition
Central Europe (Frech 1902; Schmidt 1924; Vöhringer 1960): Pseudarietites silesiacus Frech, 1902; Pseudarietites westfalicus Schmidt, 1924; Pseudarietites subtilis Vöhringer, 1960; Pseudarietites serratus Vöhringer, 1960.
South China (Ruan 1981): Pseudarietites rotatilis Ruan, 1981.
Remarks
Pseudarietites differs from Paprothites in the presence of ventral furrows and a raised keel. Paralytoceras, unlike Pseudarietites, has a combination of sharp ribs and spiral lines. Rodingites gen. nov. has a more strongly compressed whorl profile with acute venter and a very prominent attached keel.

description: Trithemis annulata (Palisot de Beauvois, 1807) is first reported for the Region of Trentino-Alto Adige/Südtirol in the central eastern Alps. A large breeding population was observed at Lake Caldaro in August and September 2023, along with two solitary males at other lakes. No other records of T. annulata were made at 16 other locations within the region. This represents the first record of this species within the Alps and thus exemplifies the rapid range expansion this species has undertaken across Europe during recent years.

Additional material
GERMANY • 1 specimen; Rhenish Mountains, Oberrödinghausen, railway cutting; Hangenberg Limestone, bed 1; Weyer 1993–1994 Coll.; MB.C.31222.
Description
Holotype GPIT-PV-63964 is the larger of only two fragments available (Fig. 115C). It is part of a specimen only about 10 mm in diameter, consisting of only one whorl segment. The conch is apparently rather widely umbilicate and the whorl profile is crescent-shaped. There is a broad, weakly serrated keel on the middle of the venter. On the flank there are coarse, rounded ribs with a concave course; they already disappear on the outer venter at some distance from the keel.
Remarks
It is not completely clear that Pseudarietites serratus belongs to this genus; however, the form of the venter with two longitudinal grooves and the keel between the grooves speak for this attribution. The specimen illustrated by Korn (1988b) as “ Paralytoceras cf. serratum ” is poorly preserved and it is not clear if it belongs to this species. Because of the insufficient material, the species can only tentatively be attributed to Pseudarietites.
Pseudarietites serratus differs from the other species of the genus in the broad, crescent-shaped whorl section and the noded keel.

description: We present an experimental and theoretical study of the polarized photoluminescence spectrum of single semiconductor quantum dots in various charge states. We compare our high resolution polarization sensitive spectral measurements with a new many-carrier theoretical model, which was developed for this purpose. The model considers both the isotropic and anisotropic exchange interactions between all participating electron-hole pairs. With this addition, we calculate both the energies and polarizations of all optical transitions between collective, quantum dot confined charge carrier states. We succeed in identifying most of the measured spectral lines. In particular, the lines resulting from singly-, doubly- and triply- negatively charged excitons and biexcitons. We demonstrate that lines emanating from evenly charged states are linearly polarized. Their polarization direction does not necessarily coincide with the traditional crystallographic direction. It depends on the shells of the single carriers, which participate in the recombination process.

Scaling properties at the interface between different critical subsystems: The Ashkin-Teller model

description: We consider two critical semi-infinite subsystems with different critical exponents and couple them through their surfaces. The critical behavior at the interface, influenced by the critical fluctuations of the two subsystems, can be quite rich. In order to examine the various possibilities, we study a system composed of two coupled Ashkin-Teller models with different four-spin couplings epsilon, on the two sides of the junction. By varying epsilon, some bulk and surface critical exponents of the two subsystems are continuously modified, which in turn changes the interface critical behavior. In particular we study the marginal situation, for which magnetic critical exponents at the interface vary continuously with the strength of the interaction parameter. The behavior expected from scaling arguments is checked by DMRG calculations.
