description: The study of open cluster metallicities helps to understand the local stellar formation and evolution throughout the Milky Way. Its metallicity gradient is an important tracer for the Galactic formation in a global sense. Because open clusters can be treated in a statistical way, the error of the cluster mean is minimized. Our final goal is a semi-automatic statistical robust method to estimate the metallicity of a statistically significant number of open clusters based on Johnson BV data of their members, an algorithm that can easily be extended to other photometric systems for a systematic investigation. This method incorporates evolutionary grids for different metallicities and a calibration of the effective temperature and luminosity. With cluster parameters (age, reddening and distance) it is possible to estimate the metallicity from a statistical point of view. The iterative process includes an intrinsic consistency check of the starting input parameters and allows us to modify them. We extensively tested the method with published data for the Hyades and selected sixteen open clusters within 1000pc around the Sun with available and reliable Johnson BV measurements. In addition, Berkeley 29, with a distance of about 15kpc was chosen. For several targets we are able to compare our result with published ones which yielded a very good coincidence (including Berkeley 29).

description: Correct development and maintenance of neuronal architecture is required for proper brain function. In this thesis, I found a natural product, ursolic acid, exhibits remarkable neuroprotective effects. UA prevents the neurodevelopmental and neurodegenerative defects in Caenorhabditis elegans. Mechanistically, the protective effects of UA against neurodegeneration act by modulating the sphingolipid metabolism to increase the production of sphingosine-1-phosphate, a neuroprotective sphingolipid. Specifically, enhanced S1P production in the intestine is essential for UA neuroprotection. Collectively, my results highlight the neuroprotective properties of UA and reveal a novel mechanism of UA neuroprotection that links intestinal sphingolipid metabolism modulation to neuronal health.

description: We discuss the alpha-muon sticking coefficient in the muon-catalysed d-t fusion in the framework of the Constrained Molecular Dynamics model. Especially the influence of muonic chaotic dynamics on the sticking coefficient is brought into focus. The chaotic motion of the muon affects not only the fusion cross section but also the muon-alpha sticking coefficient. Chaotic systems lead to lar ger enhancements with respect to regular systems because of the reduction of the tunneling region. Moreover they give smaller sticking probabilities than those of regular events. By utilizing a characteristic of the chaotic dynamics one can avoid losing the muon in the muCF cycle. W e propose that the application of the so-called microwave ionization of a Rydberg atom to the present case could lead to the enhancement of the reactivation process by using X-rays.

description: In 1990 rescue excavations by the University of Birmingham, funded jointly by Showerings Ltd and English Heritage, revealed over 2 ha. of a Romano-British roadside settlement beside the Fosse Way in Somerset. Fosse Lane can now take its place among the better known of the smaller towns and roadside settlements of Roman Britain. The excavations revealed evidence for a typical, agricultural and minor industrial centre, developing from the end of the 1st century AD and with its floruit in the 4th. Streets, plot layouts, plans of both timber-frame and stone buildings, and several small cemeteries were revealed, including one possibly Christian burial group
Value consensus, self-evaluation and interpersonal attraction
Creators: name: Archibald, W. Peter
Publisher: name: University of British Columbia
Year: 2011

description: In a previous study (Deutsch and Solomon, 1959) it had been hypothesized that if another evaluated an actor in a manner consistent with or similar to that actor's evaluation of himself, the other -would be positively attractive'; if the other's, evaluation were inconsistent with or dissimilar to the actor's evaluation of himself, the other would be negatively attractive. It was found, however, that equally consistent and inconsistent others were not equally positively and negatively attractive. This study attempted to provide an explanation for these results. It was suggested that the principal source of attraction toward the other in the previous study was not in the other's evaluation of the actor per se, but rather in the perception of the other's desire or lack of desire for group success, the experimental situation having been such that actor and other were interdependent for the success of their team in competition with another team. A similar experiment was conducted where it was found that males who regarded group success as being important were positively attracted toward others who desired group success and negatively attracted toward others who did not desire group success, regardless of whether or not the evaluations these others made of the subjects' performances were consistent with the subjects' own evaluations of their performances. While females with positive evaluations of their own performances were positively or negatively attracted toward others who did or did not desire group success, respectively, females with negative evaluations of their own performances were positively attracted toward those others whose evaluations of them were positive or supportive and negatively attracted toward those others whose evaluations of them were negative or non-supportive. Consistent with other findings in the field is the interpretation that females place much more importance upon supportive than upon competitive aspects of situations, and that the supportive rather than the competitive aspects are the issues which determine the attractiveness of others.

description: The properties of the phonon-induced interaction between electrons are studied using the local density approximation (LDA). Restricting the electron momenta to the Fermi surface we find generally that this interaction has a pronounced peak for large momentum transfers and that the interband contributions between bonding and antibonding band are of the same magnitude as the intraband ones. Results are given for various symmetry averages of this interaction over the Fermi surface. In particular, we find that the dimensionless coupling constant in the d-wave channel $λ^d$, relevant for superconductivity, is only 0.022, i.e., even about ten times smaller than the small value of the s-wave channel. Similarly, the LDA contribution to the resistivity is about a factor 10 times smaller than the observed resistivity suggesting that phonons are not the important low-energy excitations in high-T$_c$ oxides.

description: In November 2014, Dr Arnoldus Tiniap from the West Papua provincial health department presented some of the results of the 2013 Integrated Bio-Behavioural Survey (IBBS), which is the most recent Tanah Papua–wide survey of HIV indicators, including HIV prevalence, knowledge of HIV, sexual behaviour and condom use. His presentation was a key component of the workshop 'Developing an HIV Prevention and Control Strategy for Papuans in Tanah Papua' (see Munro 2015).1 It has been seven years since the last IBBS was conducted in Tanah Papua, and the results were greatly anticipated by those in attendance. The results have yet to be made available beyond certain organisations in Indonesia, but this In Brief presents a recap of Dr Tiniap's workshop presentation to facilitate access to this important new data, and to encourage further research on particular themes.

description: We present CCD BV and JHK$_{s}$ 2MASS photometric data for the open cluster NGC 1513. We observed 609 stars in the direction of the cluster up to a limiting magnitude of $V\sim19$ mag. The star count method shows that the centre of the cluster lies at $α_{2000}=04^{h}09^{m}36^{s}$, $δ_{2000}=49^{\circ}28^{'}43^{''}$ and its angular size is $r=10$ arcmin. The optical and near-infrared two-colour diagrams reveal the colour excesses in the direction of the cluster as $E(B-V)=0.68\pm0.06$, $E(J-H)=0.21\pm0.02$ and $E(J-K_{s})=0.33\pm0.04$ mag. These results are consistent with normal interstellar extinction values. Optical and near-infrared Zero Age Main-Sequences (ZAMS) provided an average distance modulus of $(m-M)_{0}=10.80\pm0.13$ mag, which can be translated into a distance of $1440\pm80$ pc. Finally, using Padova isochrones we determined the metallicity and age of the cluster as $Z=0.015\pm 0.004$ ($[M/H]=-0.10 \pm 0.10$ dex) and $\log (t/yr) = 8.40\pm0.04$, respectively.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We reconsider the analysis done by Kazama and Yokoi in arXiv:0801.1561 (hep-th). We find that although the right vacuum of the theory is the one associated to massless normal ordering (MNO), phase space normal ordering (PNO) plays crucial role in the analysis in the following way. While defining the quantum energy-momentum (EM) tensor one needs to take into account the field redefinition relating the space-time field and the corresponding world-sheet coupling. We argue that for a simple off-shell ansatz for the background this field redefinition can be taken to be identity if the interaction term is ordered according to PNO. This definition reproduces the correct physical spectrum when the background is on-shell. We further show that the right way to extract the effective equation of motion from the Virasoro anomaly is to first order the anomaly terms according to PNO at a finite regularization parameter $\eps$ and then take the $\eps \to 0$ limit. This prescription fixes an ambiguity in taking the limit for certain bosonic and fermionic contributions to the Virasoro anomaly and is the natural one to consider given the above definition of the EM tensor.

τοὐπὶ τῇ φακῇ μύρον (Sopater fr. 13, 1): Odysseus the Hedonist
Creators: name: Papachrysostomou, Athina
Publisher: name: Frammenti sulla Scena (online)
Year: 2021

description: The paper advances a new interpretation of the proverb τοὐπὶ τῇ φακῇ μύρον (“the perfume in the lentil-soup”) as attested in Sopater’s single surviving fragment from his play Nekyia, where it is used to satirically describe Odysseus. Sopater’s tiny fragment (one line and a half) reveals a mere, albeit strong, satirical tone towards Odysseus; yet, the essence of this satire is left entirely unexplained. Instead of the common view that the proverb presently conveys a notion of incongruity (as it does in other texts), the paper argues that here we need to allow for (if not implement) an alternative interpretation, that of hedonism. The argument in favour of this new interpretation is based on a number of ancient testimonies (including Aristotle’s) regarding both the proverb itself (provenance and gloss) and the later reception and misconstruing of Odysseus’ figure as a hedonist (as attested in ancient scholia on Homer, Athenaeus, and the comic tradition).

The competition-common enemy graph of a doubly partial order is also known to be an interval graph unless it contains a cycle of length 4 as an induced subgraph. In this paper, we show that the niche graph of a doubly partial order is not necessarily an interval graph. In fact, we prove that, for each integer n at least 4, there exists a doubly partial order whose niche graph contains an induced subgraph isomorphic to a cycle of length n. We also show that if the niche graph of a doubly partial order is triangle-free, then it is an interval graph.

Can a bot book that hotel for you? A survey of e-commerce web services for Austrian and German tourism

Publisher: name: Zenodo

Subjects: semantic technologies, e-commerce, web services, schema.org

description: E-commerce of tourism services has already been an indispensable part of the tourism industry. Given the recent developments in Artificial Intelligence, particularly in conversational AI technology, it is not hard to see that the Intelligent Personal Assistants like Amazon Alexa and Google Assistant will be major channels for booking hotel rooms or buying tickets for events. The web services that serve such tourism services are statically integrated into these AI applications in the current situation. Such a manual approach would not be comprehensive and scalable, assuming a high fragmentation and heterogeneity of services and service providers. Web services should be described semantically to enable automation, so intelligent applications can select correct web services and guide their users to reach their goals.
 In this survey, we provide a review of the web services for e-commerce in tourism, in order to identify (a) to what extent tourism services are bookable online (b) what is the level of fragmentation among the e-commerce web services. We provide the results based on the Destination Management Organizations (DMOs) in Austria and Tourism Marketing Organizations (TMOs) in Germany.

description: This article focuses on the mathematical problem of existence and uniqueness of BSDE with a random terminal time which is a general random variable but not a stopping time, as it has been usually the case in the previous literature of BSDE with random terminal time. The main motivation of this work is a financial or actuarial problem of hedging of defaultable contingent claims or life insurance contracts, for which the terminal time is a default time or a death time, which are not stopping times. We have to use progressive enlargement of the Brownian filtration, and to solve the obtained BSDE under this enlarged filtration. This work gives a solution to the mathematical problem and proves the existence and uniqueness of solutions of such BSDE under certain general conditions. This approach is applied to the financial problem of hedging of defaultable contingent claims, and an expression of the hedging strategy is given for a defaultable contingent claim or a life insurance contract.

description: Languaging is a manifestation of intelligent human action that enables selves toseek and to co-articulate  functional  fits  between  self  and  selected  aspects  of  theself'ssocial  and  cultural environments. Selves  have  open-ended  endogenous  tendencies  that  strive  for  articulation  in social situations. The final products of these tendencies–specific utterances–have functional capacities to enter into co-articulated relations with the other functioning components of larger-scale socio-affective-cognitive assemblages. Internal processes of microgenetic construction that have their origins in the pre-linguistic infra-structure of the self are corporeally schematized and entrained to and shaped by global order parameters, e.g., lexicogrammatical pattern.Intrinsic functional constraints  on languaging activity are the work of a complex  non-optimized system (the self) that draws on available resources in context-sensitive ways in order to yield social and cognitive outcomes.Infant proto-language is a guide to the emergence of these constraints.
The use of climatic data to estimate irrigation water requirements in the south central interior of British Columbia
Creators: name: O'Riordan, Jonathan
Publisher: name: University of British Columbia
Year: 2011

description: Climatic data observed at six meteorological recording stations in the south central Interior of British Columbia were used to analyse the temporal and geographical variations in the frequency, intensity and duration of various climatic phenomena that affect the supply and demand of water by growing crops. Rather than using average values, the relative frequencies of occurrence of each element or combination of elements were examined, in order that a more objective picture of the range of conditions experienced within the region during the growing season might be obtained. An inspection of the moisture supply patterns indicated that greater amounts of precipitation tended to occur during the earlier half of the growing season at most stations, the month of June experiencing a definite maximum. However, natural precipitation would appear to be less effective for plant growth than its absolute totals suggest, due to its tendency to be concentrated into a few days per month. An analysis of the occurrence of wet and dry spells during the growing season using two probability models supported these facts, the highest frequency of wet spells occurring in June, while the lower probabilities of wet spells in July and August indicated an increase in the length of dry spells during the second half of the growing season. Although it is known that at least four weather elements affect water loss by crops (radiation, temperature, wind and water pressure deficit), daily data were only available for two of these elements, namely air temperature and relative humidity. An examination of the relative frequencies of their occurrence showed that the evaporative power of the air remained relatively low until the end of June, after which it increased sharply as these two elements combined in such a manner that they intensified evaporation loss. This fact was further illustrated when their joint daily observations were combined in a frequency table, both July and August experiencing the highest relative frequencies of torrid days (hot days with low relative humidities). The conclusions were further verified when the actual amounts of irrigation water were computed at selected stations by estimating potential evapotranspiration rates from Penman's empirical formula and using the soil budget technique. At all stations except Lytton, little irrigation was required in most years until the beginning of July, unless the soils had low moisture storage capacities, but from July to September the required irrigation amounts were considerably higher, a fact that was due to both the increased dryness of the atmosphere and to the previous depletion of the readily available soil moisture.

description: Delayed cerebral ischemia (DCI) due to cerebral vasospasm following aneurysmal subarachnoid hemor‐rhage (aSAH) has long been recognized as a major source of morbidity and mortality. Early detection ofcerebral vasospasm and identification of patients who are likely to become symptomatic is crucial to guideaggressive medical and/or endovascular interventions. Magnetic resonance imaging using arterial spin-label(ASL) is a noninvasive mean for assessing cerebral blood flow and is based on direct magnetic labeling ofarterial blood water protons. The diagnostic role of ASL in acute ischemic stroke, epilepsy, and neurodege‐nerative disorders has been explained in multiple studies but its ability to predict vasospasm in aSAH hasnot been published before. The purpose of this study is to highlight the diagnostic implications of differentperfusion patterns of ASL in patients with aSAH which can be utilized to prevent DCI in such patientswhen other commonly used modalities are not available, contraindicated, or fail to detect vasospasm.

description: The inverse first-passage problem for a Wiener process $(W_t)_{t\ge0}$ seeks to determine a function $b{}:{}\mathbb{R}_+\to\mathbb{R}$ such that \[τ=\inf\{t>0| W_t\ge b(t)\}\] has a given law. In this paper two methods for approximating the unknown function $b$ are presented. The errors of the two methods are studied. A set of examples illustrates the methods. Possible applications are enlighted.

On a non-isothermal model for nematic liquid crystals

Subjects: subject: Analysis of PDEs (math.AP)

description: A model describing the evolution of a liquid crystal substance in the nematic phase is investigated in terms of three basic state variables: the {\it absolute temperature} $\teta$, the {\it velocity field} $\ub$, and the {\it director field} $\bd$, representing preferred orientation of molecules in a neighborhood of any point of a reference domain. The time evolution of the velocity field is governed by the incompressible Navier-Stokes system, with a non-isotropic stress tensor depending on the gradients of the velocity and of the director field $\bd$, where the transport (viscosity) coefficients vary with temperature. The dynamics of $\bd$ is described by means of a parabolic equation of Ginzburg-Landau type, with a suitable penalization term to relax the constraint $|\bd | = 1$. The system is supplemented by a heat equation, where the heat flux is given by a variant of Fourier's law, depending also on the director field $\bd$. The proposed model is shown compatible with \emph{First and Second laws} of thermodynamics, and the existence of global-in-time weak solutions for the resulting PDE system is established, without any essential restriction on the size of the data.

Non-linear waves in a Quark Gluon Plasma

description: Recent measurements at RHIC suggest that a nearly perfect fluid of quarks and gluons is produced in AA collisions. Moreover the passage of supersonic partons through this medium seems to produce waves. These waves might pile up and form Mach cones, which would manifest themselves in the so called away-side jets, forming a broad structure in the angular distribution of the particles recoiling against a trigger jet of moderate energy. In most of the theoretical descriptions of these phenomena, the hydrodynamic equations are linearized for simplicity. We propose an alternative explanation for the observed broadening of the away-side peak. It is based on hydrodynamics but it is a consequence of the non-linearities of the equations, which instead of simple waves may lead to localized waves or even solitons. We investigate in detail the consequences of including the non-linear terms. We use a simple equation of state for the QGP and expand the hydrodynamic equations around equilibrium configurations. The resulting differential equations describe the propagation of perturbations in the energy density. We solve them numerically and find that localized perturbations can propagate for long distances in the plasma. Under certain conditions our solutions mimick the propagation of Korteweg - de Vries solitons.

description: Dans  cette  contribution,  nous  souhaitons  mettre  en relief le  rôle joué  par  la  matérialité dans la constitution des formes sémiotiques. La notion de matérialité dépasse les aspects relatifs  à  la  constitution  de  la  face  signifiante  des  signes  pris isolément,  et  oriente l’attention  vers  l’agentivité  des  matériaux  à  l’œuvre dans  tout  type  d’interaction symbolique. Ainsi, la réflexion sur les formes sémiotiques inclut d’autres processus et «objets» sémiotiques, allant du vivant jusqu’aux sémioses anthropiques. Dans ce cadre, nous nous attarderons sur la relation entre d’un côté, la notion d’«hyperobjet», élaborée par  le  philosophe  Timothy  Morton  dans  l’enceinte  du  matérialisme  et  du  réalisme spéculatif à visée écologique, et de l’autre, celle de «constructionde niche», attestée dans les recherches en anthropologie évolutionniste et en biosémiotique.

description: In an attempt to understand why the dominating magnetic field observed in the von-Kármán-Sodium (VKS) dynamo experiment is axisymmetric, we investigate in the present paper the ability of mean field models to generate axisymmetric eigenmodes in cylindrical geometries. An $α$-effect is added to the induction equation and we identify reasonable and necessary properties of the $α$ distribution so that axisymmetric eigenmodes are generated. The parametric study is done with two different simulation codes. We find that simple distributions of $α$-effect, either concentrated in the disk neighbourhood or occupying the bulk of the flow, require unrealistically large values of the parameter $α$ to explain the VKS observations.
Some factors affecting the distribution and abundance of the chiselmouth (Acrocheilus alutaceus)
Creators: name: Moodie, Gordon Eric Edmund
Publisher: name: University of British Columbia
Year: 2011

description: Some features of the biology of Acrochellus alutaceus were investigated with the purpose of explaining the rarity and disjunct distribution of the species in British Columbia. Two populations were compared, one in a lacustrine environment, in which the species is often rare, the other in a riverine environment, in which the species is usually common. Age and growth analysis of the two populations showed that in the river population growth continued for one year longer than in the lake population. Maximum age attained in both populations was 6 years. Observations of feeding behavior in the field and laboratory suggested that the unusual lower jaw of the fish is an adaptation to scraping Aufwuchs, chiefly filamentous algae, from smooth substrates. Analysis of diet in the two habitats showed a much more restricted diet in the river. It is concluded that the growth of the type of food consumed by Acrocheilus and the occurence of a substrate suitable for feeding will be most abundant and commonly found in warm rivers. The temperature required for spawning by Acrocheilus is probably higher than that of other local cyprinids. This may also limit the distribution of the species. In both habitats, diet changes with age; young fish lack the scraper-like lower jaw and eat principally insects,. Diatoms ingested with filamentous algae probably provide the chief source of nutrition. Filamentous algae undergoes little or no digestive breakdown. The possibility of interspecific competition for food and spawning sites in the lake is discussed.
