description: Статья посвящена описанию технологии изготовления и использования небольшой коллекции костяных пряжек, выявленных среди богатого инвентаря неординарных погребений доно-волжской абашевской культуры Второго Липецкого кургана (раскопки 2011 г.). Все пряжки Липецкого кургана изготовлены из фрагментов компакты трубчатых костей крупных копытных. Трубчатая кость раскалывалась на длинные продольные пластины, из которых вырезались прямоугольные или подквадратные пластины меньших размеров. Затем углы заготовок либо срезали, либо стачивали на абразиве, добиваясь овальной или круглой формы изделий. На внешних и внутренних поверхностях всех пряжек зафиксированы разнонаправленные следы тонкого и очень тонкого абразива. После абразивной обработки заготовок, просверливались большие и маленькие отверстия. Как правило, сначала сверлились центральные отверстия в пряжках. Использовались лучковые сверла, оставившие следы своих муфт вокруг центральных отверстий. Подобные следы вращения вокруг отверстий встречаются на пряжках различных регионов. Пряжки после сверления отверстий окончательно обрабатывались тонким абразивом. На всех пряжках из погребений 2 Липецкого кургана зафиксированы следы сработанности. Использование пряжек происходило с разной интенсивностью. Соотношение осей сработанности обеих поверхностей пряжек позволяет реконструировать положение изделий при эксплуатации и считать их собственно поясными пряжками. В статье также приводится графическая реконструкция крепления костяных пряжек к ремням.
description: The paper describes the fabrication method and the use of a small collection of bone buckles discovered along with the luxurious grave goods from the uncommon burials of the Don-Volga Abashevo culture Second Lipetsk barrow (excavation of 2011). All buckles of Lipetsk kurgan made from fragments compact tubular bones of large ungulates. Tubular bone was split on long longitudinal plates, from which cut out rectangular or square plates smaller size. Then, angles or blanks cut or grind off by means an abrasive to achieve a circular or oval shape. On the external and internal surfaces of buckles fixed multidirectional traces of thin and very fine abrasive. After abrasive processing workpieces, large and small holes are drilled. As a rule, the central holes drilled into the buckle first. Buckles after drilling was worked up fine abrasive. Traces of wear visible on all the buckles from burials 2 of Lipetsk kurgan. Using of buckles occurred with varying intensity. The ratio the wear and tear, both surfaces of buckles allows you to reconstruct the position of items in operation and consider them as belt buckles. Graphic reconstruction of fixing bone buckles to the straps is given in the article as well.

description: Lonas annua (L.) Vines & Druce (Asteraceae), commonly known as African Daisy or Yellow Ageratum is a rare therophyte native to northwestern Africa (Algeria, Morocco, and Tunisia) and Italy (Sicily and Sardinia). In the present study, the chemical composition of the essential oil from aerial parts of Lonas annua was analyzed by GC-MS. No one report has been previously published on the essential oil of this species. The results showed the presence of large quantity of two unusual metabolites 2,3-dihydrofarnesol (41.64%), and acenaphthene (36.18%). Chemotaxonomic considerations were carried out in order to confirm the phylogenetic reconstructions of Anthemideae.

description: We address the question whether the lightest scalar mesons sigma and kappa are tetraquarks, as is strongly supported by many phenomenological studies. We present a search for possible light tetraquark states with J^PC=0^++ and I=0, 1/2, 3/2, 2 on the lattice. The spectrum is determined using the generalized eigenvalue method with a number of tetraquark interpolators at the source and the sink. In all the channels, we unavoidably find lowest scattering states pi(k)pi(-k) or K(k)pi(-k) with back-to-back momentum k=0,2*pi/L,.. . However, we find an additional light state in the I=0 and I=1/2 channels, which may be related to the observed resonances sigma and kappa with a strong tetraquark component. In the exotic repulsive channels I=2 and I=3/2, where no resonance is observed, we find no light state in addition to the scattering states.

description: We give sharp point-wise bounds in the weight-aspect on fourth moments of modular forms on arithmetic hyperbolic surfaces associated to Eichler orders. Therefore we strengthen a result of Xia and extend it to co-compact lattices. We realize this fourth moment by constructing a holomorphic theta kernel on $\mathbf{G} \times \mathbf{G} \times \mathbf{SL}_{2}$, for $\mathbf{G}$ an indefinite inner-form of $\mathbf{SL}_2$ over $\mathbb{Q}$, based on the Bergman kernel, and considering its $L^2$-norm in the Weil variable. The constructed theta kernel further gives rise to new elementary theta series for integral quadratic forms of signature $(2,2)$.

description: From an EtOAc-soluble fraction of the roots of Paramignya trimera, one undescribed chromene derivative, paratrimerin Z (1), was isolated. Its structure was elucidated on the basis of NMR spectroscopic interpretation. The absolute configuration of 1 was determined by the specific rotation analysis of its acid-catalyzed hydrolysis product. Paratrimerin Z (1), at a concentration of 100 μM, did not show cytotoxicity against Hep3B human liver cancer cell line.
Alienation and aestheticism in the art of Leonard Cohen
Creators: name: Panter, Jack Bryan
Publisher: name: University of British Columbia
Year: 2011

description: The art of Leonard Cohen has been the subject of several recent literary studies and numerous short reviews. Often superficial features of his work distract those studying him and lead them to conclusions which do not account for a number of more important qualities which lie at the center of his art. Cohen's point of view, as it is manifested in his art, is frequently given only cursory attention and this leads to a misinterpretation of his work. The critical approach used in this thesis is designed to illuminate Cohen's position in relation to his art and account for the various apparently contradictory features noticed in his work. This study consists of an examination of Leonard Cohen's prose and poetry from a critical perspective centering on Cohen's "willed self-alienated" point of view. The self-alienated center of consciousness from which Cohen's work originates is delineated and its adequacy as a source of aesthetic and philosophical values discussed. The method of inquiry is mainly interpretive, but Cohen's art is also discussed in relation to several of the main themes and conventions of modern literature from an historical point of view. The basic conclusion of this study is that Cohen's "willed self-alienated" point of view is the source of what are called dynamic aesthetic values. Willed self-alienation may briefly be defined as a chosen mode of existence in which the individual maintains a continuous process of negation of virtually all forms, systems, beliefs, and habits which are in themselves "static" and therefore contrary to life. This process results in a capacity to be self-creative because the individual feels no allegiance to a particular self-conception. Cohen uses this point of view in his art in a way that allows him to exhibit a variety of apparently contradictory traits. This fragmentation of the consciousness at the center of the art must be grasped if Cohen's work is to be fully appreciated. The basic impulse of the willfully self-alienated individual is to "become" other than he is at any particular point in time. The temporal emphasis for such a mode of existence is, therefore, the present moment. An aesthetic perspective emerges directly out of this situation. The main temporal focus of aesthetic concerns is the present and, in the arts, "moments" of perfection. Cohen's willed self-alienation does not permit him to dwell in single perfect moments like Breavman in The Favorite Game. Cohen is concerned with the eternal or expanded moment of consciousness in which the individual is aware of his life and creative ability. The values which emerge from Cohen's art are directly related to a fusion of his willed self-alienated point of view and dynamic aestheticism.

description: Background: Hospital professionals are “dual agents” who may face dilemmas between their commitment to patients’ clinical needs and hospitals’ financial sustainability. This study examines whether and how hospital professionals balance or reconcile clinical and economic considerations in their decision-making in two countries with activity-based payment systems. Methods: We conducted 46 semi-structured interviews with hospital managers, chief physicians and practicing physicians in five German and five Israeli hospitals in 2018/2019. We used thematic analysis to identify common topics and patterns of meaning. Results: Hospital professionals report many situations in which activity-based payment incentivizes proper treatment, and clinical and economic considerations are aligned. This is the case when efficiency can be improved, eg, by curbing unnecessary expenditures or specializing in certain procedures. When considerations are misaligned, hospital professionals have developed a range of strategies that may contribute to balancing competing considerations. These include ‘reshaping management,’ such as better planning of the entire course of treatment and improvement of the coding; and ‘reframing decision- making,’ which involves working with averages and developing tool-kits for decision- making. Conclusion: Misalignment of economic and clinical considerations does not necessarily have negative implications, if professionals manage to balance and reconcile them. Context is important in determining if considerations can be reconciled or not. Reconciling strategies are fragile and can be easily disrupted depending on context. Creating tool-kits for better decision- making, planning the treatment course in advance, working with averages, and having interdisciplinary teams to think together about ways to improve efficiency can help mitigate dilemmas of hospital professionals.
Exactly unitary discrete representations of the metaplectic transform for linear-time algorithms

description: The metaplectic transform (MT), a generalization of the Fourier transform sometimes called the linear canonical transform, is a tool used ubiquitously in modern optics, for example, when calculating the transformations of light beams in paraxial optical systems. The MT is also an essential ingredient of the geometrical-optics modeling of caustics that was recently proposed by the authors. In particular, this application relies on the near-identity MT (NIMT); however, the NIMT approximation used so far is not exactly unitary and leads to numerical instability. Here, we develop a discrete MT that is exactly unitary, and approximate it to obtain a discrete NIMT that is also unitary and can be computed in linear time. We prove that the discrete NIMT converges to the discrete MT when iterated, thereby allowing the NIMT to compute MTs that are not necessarily near-identity. We then demonstrate the new algorithms with a series of examples.

description: The structure of binary As_xS_{1-x} glasses is elucidated using modulated-DSC, Raman scattering, IR reflectance and molar volume experiments over a wide range (8%29.5%. Raman scattering supported by first principles cluster calculations reveal existence of both pyramidal (PYR, As(S1/2)3) and quasi-tetrahedral(QT, S=As(S1/2)3) local structures. The QT unit concentrations show a global maximum in the IP, while the concentration of PYR units becomes comparable to those of QT units in the phase, suggesting that both these local structures contribute to the width of the IP. The IP centroid in the sulfides is significantly shifted to lower As content x than in corresponding selenides, a feature identified with excess chalcogen partially segregating from the backbone in the sulfides, but forming part of the backbone in selenides. These ideas are corroborated by the proportionately larger free volumes of sulfides than selenides, and the absence of chemical bond strength scaling of Tgs between As-sulfides and As-selenides. Low-frequency Raman modes increase in scattering strength linearly as As content x of glasses decreases from x = 20% to 8%, with a slope that is close to the floppy mode fraction in flexible glasses predicted by rigidity theory. These results show that floppy modes contribute to the excess vibrations observed at low frequency. In the intermediate and stressed rigid elastic phases low-frequency Raman modes persist and are identified as boson modes. Some consequences of the present findings on the optoelectronic properties of these glasses is commented upon.

description: According to the classical special theory of relativity any nonstationary system moving with velocity $v$ must evolve (e.g., decay) $1/γ$ times slower than the system at rest, $γ=(1-v^2)^{-1/2}$ (the Einstein retardation ER). Quantum mechanics allows one to calculate the evolution of both systems separately and to compare them thus verifying ER. It is shown here that ER is not valid for a simple system: the spreading packet of the free spinless particle. Earlier it was shown that ER does not hold for some other systems. So one may state that ER is not a universal kinematic law in quantum mechanics.

description: Esej jest poświęcony perspektywie zdolności Marthy Nussbaum. Jest to złożona wizja etyki społecznej, którą badam jako utopijną teorię wychowania. Ma ona trzy fundamenty filozoficzne. Pierwszym jest filozofia moralna Immanuela Kanta, według której każda jednostka powinna być traktowana jako cel sam w sobie. Drugim – postulat Karola Marksa, by wyzwolić ludzkie potencjały, zduszone przez alienację. Trzeci stanowi koncepcja praw kobiet i mniejszości, jaką prezentuje w swoich dziełach John Stuart Mill. Jednak refleksja Nussbaum wykracza daleko poza teorie powstałe w XVIII i XIX wieku, odnosząc się do współczesnego świata i wyrażając dzisiejsze postulaty emancypacyjne. Przedstawia ona listę dziesięciu podstawowych „zdolności” jednostek, których realizację powinno umożliwić sprawiedliwe społeczeństwo. Są to: życie, zdrowie, integralność fizyczna, rozum praktyczny, afiliacja, kontrola nad środowiskiem, zmysły, zabawa i wyobraźnia, a także bliskość z naturą. W integralności cielesnej chodzi o prawa reprodukcyjne oraz o dostosowanie środowiska do potrzeb osób z niepełnosprawnościami. Edukacja i wychowanie mają usuwać przeszkody w realizacji wszystkich zdolności. Wyobraźnia i logiczne myślenie rozwijają umiejętność postawienia się w sytuacji kogoś innego, a więc przeciwdziałają dyskryminacji. Celem sprawiedliwego społeczeństwa jest emancypacja wszystkich ludzi, co wymaga określonych ekonomicznych reguł. Stawia ona na kulturę humanistyczną, która byłaby dostępna dla wszystkich, uświadamiając ludziom bogactwo ich potencjałów.

description: We present a new on-the-fly (OTF) mapping of CO(J=3-2) line emission with the Atacama Submillimeter Telescope Experiment (ASTE) toward the 8' x 8' (or 10.5 x 10.5 kpc at the distance of 4.5 Mpc) region of the nearby barred spiral galaxy M 83 at an effective resolution of 25''. Due to its very high sensitivity, our CO(J=3-2) map can depict not only spiral arm structures but also spur-like substructures extended in inter-arm regions. This spur-like substructures in CO(J=3-2) emission are well coincident with the distribution of massive star forming regions traced by Halpha luminosity and Spitzer/IRAC 8 um emission. We have identified 54 CO(J=3-2) clumps as Giant Molecular-cloud Associations (GMAs) employing the CLUMPFIND algorithm, and have obtained their sizes, velocity dispersions, virial masses, and CO luminosity masses. We found that the virial parameter alpha, which is defined as the ratio of the virial mass to the CO luminosity mass, is almost unity for GMAs in spiral arms, whereas there exist some GMAs whose alpha are 3 -- 10 in the inter-arm region. We found that GMAs with higher $α$ tend not to be associated with massive star forming regions, while other virialized GMAs are. Since alpha mainly depends on velocity dispersion of the GMA, we suppose the onset of star formation in these unvirialized GMAs with higher alpha are suppressed by an increase in internal velocity dispersions of Giant Molecular Clouds within these GMAs due to shear motion.

Behind the candelabra : preventing child sexual abuse in Tasmania
Creators: name: Guerzoni, Michael Andre
Publisher: name: University Of Tasmania
Year: 2023

description: Clergy-child sexual abuse in Christian Church institutions is a prevalent criminological issue in the 21st Century. Research from academic and governmental inquiry collectively has focussed on building knowledge of clerical offenders, victims/survivors, victimisation, crime prevention, and institutional responses to abuse; particularly within the American and Irish Roman Catholic contexts. This scholarship has been fundamental in bringing care and justice to survivors and offenders, as well as in the development and implementation of child protection legislation, policies, screening requirements, training, and compensation schemes in religious and non-religious organisations around the Western world. In recent years, scholarship has moved from the previously normative focus on 'offenders with deviant sexual interests' in understanding child abuse to identifying and exploring the role of institutional cultures and environments in abuse events. By highlighting the malleable nature of individual behaviours and desires when subject to surrounding influences and variables, it has been shown how church cultures and environments precipitate child sexual abuse events; leading the otherwise normal‚ÄövÑvp person to abuse or be complicit in church secrecy. The commonality of susceptibility to sexual offending, and the role of organisational culture and environments in this process, press for an examination of the micro-level context of church organisations: what is occurring at the everyday parish today, and how this activity is influenced by clerical cultures and congregational situational factors. This dissertation provides empirical research on the child protective clerical cultures operative within the Anglican Diocese of Tasmania. Drawing from a sample of 34 clerics (29 male, 5 female) and document analysis of Diocesan policies and legislation, inquiry is directed towards understanding the clerical habitus (predispositions that guide individual beliefs and behaviours) in respect to child sexual abuse and child protection, and how this shapes clergy's everyday safe ministry practices. These reported practices are then analysed through the lens of situational crime prevention techniques to analyse the feasibility of their efficiency in minimising abuse events. The dissertation then seeks to identify clerical cultures towards child protection in Tasmania, to test the presence of an interconnection between these cultures, Diocesan structures (policies and training), and the clerical child protective habitus. In understanding the cognition, conduct and culture of clergy in the Tasmanian Anglican Church, recommendations are offered on how to make church life safer places for children.

description: This document was developed to provide a standard operating procedure (SOP) on clinical data processing for creating virtual cohorts for in-silico models. The SOP is designed for SIMCor partners as well as for the scientific community. Hence, it formulates procedures and workflows for the processing of clinical data (in particular, imaging data) in the view of generating virtual cohorts. Given the heterogeneity of data, general recommendations are provided, rather than precise steps, with specific illustrations based on the SIMCor use case: transcatheter aortic valve implantation (TAVI). Standards and guidelines for data quality, data formats and data exchange were applied, when they existed. Confronting the current workflow with the evolving practice as the project continues may lead to updates, thus subsequent iterations are foreseen.

description: A small molecular weight cationic copper(I) complex showing high luminescence quantum yield based on a thermally activated delayed fluorescence mechanism is immobilized between two 1 nm thin silicate layers. Partial ion exchange of the emitter into a synthetic layered silicate (fluorohectorite) yields an ordered heterostructure with two types of strictly alternating interlayers: a monolayer of the cationic emitter and a monolayer of hydrated Na+ cations. Osmotic swelling of the latter produces dispersions of double-stacks in which the emitter monolayer is encapsulated between two silicate layers. The electrostatic attraction of the emitter interlayer with the oppositely charged silicate layers exerts electrostatic pressure on the emitter. Compared to crystalline salt, rigid confinement for the encapsulated emitter provides improved thermal stability and increased emission quantum yield at ambient temperature. The suspension of delaminated, micrometer-sized double-stacks of 3.9 nm thickness allows for easy solution processing of low-cost optoelectronic devices, such as light-emitting electrochemical cells and organic light-emitting diodes.

description: Recently, we have presented some simple arguments supporting the existence of certain complementarity between thermodynamic quantities of temperature and energy, an idea suggested by Bohr and Heinsenberg in the early days of Quantum Mechanics. Such a complementarity is expressed as the impossibility of perform an exact simultaneous determination of the system energy and temperature by using an experimental procedure based on the thermal equilibrium with other system regarded as a measure apparatus (thermometer). In this work, we provide a simple generalization of this latter approach with the consideration of a thermodynamic situation with several control parameters.

TLC, 1H-NMR and LC-MS chemical profiles of this mushroom compared with other three genera of wild Sanghuang mushroom extracts were investigated. The TLC, 1H-NMR and LC-MS profiles of TL663 and Sanghuangporus sanghuang (SS664) were similar and significantly different from other mushrooms. These two samples indicated the same TLC chromatograms by showing prominent bands of 1 − 4 when observed under UV 254 nm and having sharp aldehyde proton signals of 3-carboxaldehyde indole type in 1H-NMR spectra. From LC-MS analyses, peaks of isolated compounds 1 − 4 and indole-3-carboxaldehyde (5) in TL663 extract and peaks of protocatechuic acid (6), caffeic aldehyde (7), caffeic acid (8) and 3,4-dihydroxybenzalacetone (9) phenolic acids in TL663 fraction were identified.

description: Parasitic isolates of Saprolegnia diclina Humphrey from Coho salmon (Oncorhynchus kitsutch Walbaum) were grown under controlled laboratory conditions to test the effect of environmental parameters on growth. This study points out the significance of medium selection and methods of determining growth in introducing variability into the results of experimental studies of parasitic Saprolegniaceae. The results indicate that there is a significant effect of temperature and pH on growth and morphological development while the effects of phosphate concentration, aeration and nitrogen sources appear to be as significant but vary with medium used or method in determining growth.

description: Acylphloroglucinols are well-known Eucalyptus secondary metabolites which exhibit a variety of structures and bioactivities. The investigation of a crude acetone extract of Eucalyptus camaldulensis leaves led to the isolation of two new acylphloroglucinols, eucalypcamals O and P (1 and 2) together with seven phloroglucinols (3–9), and a benzene derivative (10). Their chemical structures were elucidated by 1D and 2D nuclear magnetic resonance (NMR) spectroscopy and mass spectroscopy. The absolute configurations of compounds 1 and 2 were established by comparison of experimental and calculated electronic circular dichroism (ECD) data. In the putative biosynthetic pathway, eucalypcamals O and P should be derived from hetero-Diels-Alder reaction between grandinol and trans-isoeugenol.
title: Transcendent experience or the transcendence of experience? An analysis of transcendent realization in Shankara, Ibn Arabi and Meister Eckhart
Creators: name: Shah-Kazemi, Reza
Publisher: name: University of Kent
Year: 2021

description: This research aims at investigating the nature, meaning and implications of 'transcendent realization', that which is held to be the summit of spiritual realization by three renowned and highly influential mystics; Shankara. from the Hindu tradition, Ibn Arabi, from the Islamic tradition and Meister Eckhart, from the Christian tradition. The central methodological principle of the analysis is interntionalityl the opening chapter situates and discusses this principle in relation to the phenomenological method, while also highlighting the importance of the concept of transcendence for the contemporary discussion in comparative mysticism between the 'contextualist' school of Steven Katz and the 'Pure Consciousness' school of Robert Forman. Three chapters follow, dealing in turn with each of the three mystics, analyzing in some depth their respective pronouncements on transcendence; this theme is explored in both doctrinal and realizational terms: what transcendence means objectively, and how it is assimilated, realized or attained subjectively, with what pre-conditions and with what ramifications. The penultimate chapter brings together those features of transcendence shared in common bu the three mystics; differences as well as similarities are analyzed here. The final chapter consists in a critique of recent scholarly approaches to mysticism. In the light of the conclusions presented in this thesis, the reductive aspect of these approaches - their failure to take into account fully the nature and implications of trascendence with regard to mystical experience - is clearly discerned. The central conclusion of the thesis is that transcendent realization consists in the realization of identity with the Absolute, an identity which strictly transcends the individual, and by that very token transcends all possible 'experience' defined in relation to the individual; it also necessarily transcends all contextual factors that presuppose the individual as the ground of their mediating influence. The realization of this transcendent identity is incommunicable as regards its intrinsic nature but can be extrinsically described as the realization of the unique and undifferentiable Essence of 'Being-Consciousness-Bliss'.

description: In the search of cytotoxic dihydrochalcones, this investigation led to the isolation of seven compounds (1-7) from Eriosema glomeratum and the preparation of eight derivatives (8-15). The cytotoxicity of samples was evaluated against lung (A549), breast (MCF-7), and cervical (HeLa) human cancer cells. The CH2Cl2/MeOH extract of the aerial part had strong cytotoxicity against all cells [IC50 11.2 (MCF-7), 8.4 (HeLa) and 13.1 (A549) μg/mL]. A strong activity was also displayed by the n-hexane fraction on MCF-7 (IC50 11.2 μg/mL). The precursor 3 and the derivative 8 were specifically found as strong cytotoxic agents toward MCF-7 (7.6 μM) and HeLa (3.1 μM), respectively and were more effective than the positive control. Derivatives 8 (3.1 μM) and 9 (21.3 μM) against HeLa were most potent than their precursor 3 (23.7 μM). This is the first preparation of 8-14 as well as the cytotoxicity of 3, 4, 8-15, fractions, and extract.
Hypothetical cosmogonic conception of the World order in the Tagar culture

THE POLE OF THE ECLIPTIC

description: The article analyses two works by V.E. Larichev, where he reveals a potential occult astral aspect of the petroglyphs dating back to the Tagar culture of the late I millennium BCE in Northern Khakassia, namely, in the foothills of the Kuznetsk Alatau at the southern submontane extremity of Chetvyorty Sunduk. Professor Larichev’s astral compositions provide the opportunity for further archaeo-astronomical research. The characters of the pictorial petroglyphic compositions represent ancient cosmic symbols of not only the Tagar culture, but also of many Eurasian peoples’ cultures. This is the cosmic unity which joined minds of ancient representatives of various Eurasian cultures and generated in each of them the idea of a Heroic epos, Heroes bearing different names, but the plotline being actually the same, including fighting, development and defeating similar enemies. The plot is the same and it was suggested by the circumpolar pattern of the northern stellar sky, similar for all the inhabitants of the northern hemisphere of the Earth at the same Age. The petroglyphs of Chetvyorty Sunduk prove ancient people’s knowledge of such phenomena as the precession, the motion of the celestial pole among stars and the location of the pole of the ecliptic near Draco’s «head».

PID for repositories

description: Presentation slides "PIDs for research (data) repositories"; presentation held Thursday January 28, 2021, 11:00 - 11:30 UTC at PIDapalooza 2021. Abstract “Every day, once a day, give yourself a present. Don't plan it. Don't wait for it. Just let it happen. It could be [...] a catnap in your office chair, [...] two cups of good, hot black coffee… or PIDs for research repositories.” (an almost original quotation from Twin Peaks)

 The re3data COREF project invites all participants to join us with a delicious piece of cake and a nice cup of coffee or tea to discuss the topic of PIDs for research (data) repositories. There will be pie charts and people are allowed to take notes on their table cloths. Of course we are interested in everyone’s opinion and will collect them via polling throughout the session. We are excited to discuss with the community how y’all would use a PID to refer to a repository and how references to repositories can be improved.

description: In the article presents the results of the multidisciplinary study conducted with the help of archaeological, physical and astronomical methods. The aim of the study was to analyze and interpret marks and drawings applied to the surface of the vessel of the Bronze Age (Srubna culture) found near the Staropetrovsky village in the northeast of the Donetsk region (the Central Donbass). The carried out calculations and measurements possible to prove that Staropetrovsky vessel is the most ancient water clock, discovered on the territory of Europe, and have approximately the same age as the oldest known ancient Egyptian water clock. Such vessels water clocks were needed for Srubna population to rituals related to the determined time of day and to mark sundial, which had recently been discovered in the Northern Black Sea Coast. Staropetrovsky vessel has marks of heliacal rising of Sirius and it is an ancient astronomical auxiliary instrument for determining the time at night.

description: The index of Erodible Fraction (EF) component against wind is well known as a criteria of soil wind erodibility. This study was conducted to estimate the index of EF by utilizing support vector machine (SVM), artificial neural network (ANN) and genetic algorithm (GA-ANN) methods. For this reason, 95 soil samples were collected 10 cm above the soil surface of Allahabad plain in Qazvin province. Then the percentage of aggregates with a diameter of less than 0.84 mm, pH, EC, soil saturation capacity, SAR, equivalent calcium carbonate, organic matter, clay, sand and silt were measured and used in SVM, ANN and GA-ANNs model construction and testing. Results revealed that the EF had a significant correlation at the level of 1% with five soil characteristics, including pH, EC, SAR, clay and organic matter. On the other hand, the ANNs model developed for EF prediction had higher accuracy (R2 = 0.49) than the GA-ANNs model (R2 = 0.37) and SVMs model (0.02). All models were approximately overestimated and the GMER values for SVMs, ANNs and GA-ANNs models were 1.11, 1.15 and 1.08, respectively. However, according to the Akaike information criterion (AIC), all of them had similar power model estimation. Although SVMs offer good accuracy and perform fast prediction in this study, it did not perform well. This issue may be related to the complexity of the relationship between EF and soil properties.
