description: Atmospheric parameters and oxygen abundances of 825 nearby FGK stars are derived using high-quality spectra and a non-LTE analysis of the 777 nm O I triplet lines. We assign a kinematic probability for the stars to be thin-disk (P1), thick-disk (P2), and halo (P3) members. We confirm previous findings of enhanced [O/Fe] in thick-disk (P2>0.5) relative to thin-disk (P1>0.5) stars with [Fe/H]-0.2. Nevertheless, we find that the kinematic membership criterion fails at separating perfectly the stars in the [O/Fe]-[Fe/H] plane, even when a very restrictive kinematic separation is employed. Stars with "intermediate" kinematics (P1<0.7, P2<0.7) do not all populate the region of the [O/Fe]-[Fe/H] plane intermediate between the mean thin-disk and thick-disk trends, but their distribution is not necessarily bimodal. Halo stars (P3>0.5) show a large star-to-star scatter in [O/Fe]-[Fe/H], but most of it is due to stars with Galactocentric rotational velocity V-200 km/s follow an [O/Fe]-[Fe/H] relation with almost no star-to-star scatter. Early mergers with satellite galaxies explain most of our observations, but the significant fraction of disk stars with "ambiguous" kinematics and abundances suggests that scattering by molecular clouds and radial migration have both played an important role in determining the kinematic and chemical properties of solar neighborhood stars.

Causal intricacies of bias in the research system

Causal model

description: Diversity and inclusion is an important topic in society, and is being studied in various fields, including studies of science itself. Many studies on diversity and inclusion in science analyse biases in various processes of research, such as prestige bias in peer review or gender bias in citations. However, bias as a concept is not always clearly defined in this context. We propose to define bias in this context as an unjustified direct causal effect. The proposed definition of bias is closely related to the notion of procedural fairness. In this context, disparity is another frequently used term, which we also define in terms of causal mechanisms. The proposed definition of disparity is closely related to the notion of distributive fairness. These causal foundations allow us to reason about bias, disparities, and various concepts of fairness and their implications, which relate to recent discussions in artificial intelligence. We discuss the implications of the proposed definitions for studying biases in the research system, and briefly reflect on potential effects of interventions to counter biases. We believe the proposed definitions contribute to a better appreciation of the causal intricacies and an improved understanding of policy implications of studies on bias.

description: Trichoderma reesei (Hypocrea jecorina) was developed as a microbial cell factory for the heterologous expression of fungal secondary metabolites. This was achieved by inactivation of sorbicillinoid biosynthesis and construction of vectors for the rapid cloning and expression of heterologous fungal biosynthetic genes. Two types of megasynth(et)ases were used to test the strain and vectors, namely a non-reducing polyketide synthase (nr-PKS, aspks1) from Acremonium strictum and a hybrid highly-reducing PKS non-ribosomal peptide synthetase (hr-PKS-NRPS, tenS + tenC) from Beauveria bassiana. The resulting engineered T. reesei strains were able to produce the expected natural products 3-methylorcinaldehyde and pretenellin A on waste materials including potato, orange, banana and kiwi peels and barley straw. Developing T. reesei as a heterologous host for secondary metabolite production represents a new method for waste valorization by the direct conversion of waste biomass into secondary metabolites.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We consider the color suppressed (nonfactorizable) amplitude for the decay mode $\bar{B_{d}^0} \rightarrow π^0 π^{0} $. We treat the $b$-quark in the heavy quark limit and the energetic light ($u,d,s$) quarks within a variant of Large Energy Effective Theory combined with an extension of chiral quark models. Our calculated amplitude for $\bar{B_{d}^0} \rightarrow π^0 π^{0} $ is suppressed by a factor of order $Λ_{QCD}/m_b$ with respect to the factorized amplitude, as it should according to QCD-factorization. Further, for reasonable values of the (model dependent) gluon condensate and the constituent quark mass, the calculated nonfactorizable amplitude for $\bar{B_{d}^0} \rightarrow π^0 π^{0} $ can easily accomodate the experimental value. Unfortunately, the color suppressed amplitude is very sensitive to the values of these model dependent parameters. Therefore fine-tuning is necessary in order to obtain an amplitude compatible with the experimental result for $\bar{B_{d}^0} \rightarrow π^0 π^{0} $.

description: Attempting to achieve long-lasting and stable resistance using uniformly deployed rice varieties is not a sustainable approach. The real situation appears to be much more complex and dynamic, one in which pathogens quickly adapt to resistant varieties. To prevent disease epidemics, deployment should be customized and this decision will require interdisciplinary actions. This perspective article aims to highlight the current progress on disease resistance deployment to control bacterial blight in rice. Although the model system rice-Xanthomonas oryzae pv. oryzae has distinctive features that underpin the need for a case-by-case analysis, strategies to integrate those elements into a unique decision tool could be easily extended to other crops.

description: Ginkgo biloba L. – реликтовый вид голосеменных растений. Используется: – в лекарственных целях, для лечения и предупреждения проблем сосудов мозга; - для озеленения в групповых и одиночных посадках; – семена идут в пищу. Не смотря на прекрасные хозяйственно ценные характеристики, многочисленные данные о выращивании Гинко билоба в Подмосковье, растение до сих пор не районировано. Цель нашей работы – подтвердить возможность культивирования гинкго наших условиях, возможность создания массовых посадок этого растения как для сбора лекарственного сырья, так и целей озеленения. Ботанический сад Первого Московского государственного медицинского университета имени И.М. Сеченова располагается на берегу реки Москвы (55° 75' с.ш., 37° 53' в.д.). Климат умеренно-континентальный. Почвы сада наносные, супесчаные, заиленные речными отложениями, подстилаются чёрными юрскими глинами. Ginkgo biloba культивируется в ботаническом саду ПМГМУ им. И.М. Сеченова с 2008 г. Применив «Методику определения перспективности интродукции древесных растений» Уральского Государственного Лесотехнического университета, мы определили, что Гинкго билоба находится на уровне лиственницы сибирской, между сосной обыкновенной и елью сибирской и относится к классу средне перспективных и перспективных видов, Наши исследования грунтовой посадки Гинкго билоба 2008-2017 г. показали, что растения может развиваться в наших условиях и без повреждения переносить морозы до -30 °С., ледяной дождь, жару, смог. Для получения саженцев пригодны семена, полученные из южных регионов.

description: Определены средние многолетние сроки наступления основных фенологических фаз для видов Syringa vulgaris L. и S. villosa Vahl. и гибридной формой S. x chinensis Willd. в коллекции Никитского ботанического сада. Установлены значения биологических минимумов температур, необходимых изученным сиреням для возобновления вегетации и начала цветения. Выявлено, что зимой в условиях ЮБК сирени находятся в состоянии вынужденного покоя, т.к. повышение температуры воздуха выше биологического минимума, составляющего, в зависимости от таксона, от 5,1 до 6,2 °С в этот период вызывает у них кратковременное возобновление вегетации. Полученные уравнения регрессии являются математическими моделями, позволяющими, используя метеорологические данные, рассчитывать даты наступления указанных фенологических фаз в новых регионах интродукции.

description: In lungs the number of conducting airway generations as well as bifurcation patterns varies across species and shows specific characteristics relating to illnesses or gene variations. A method to characterize the topology of the mouse airway tree using scanning laser optical tomography (SLOT) tomograms is presented in this paper. It is used to test discrimination between two types of mice based on detected differences in their conducting airway pattern. Based on segmentations of the airways in these tomograms, the main spanning tree of the volume skeleton is computed. The resulting graph structure is used to distinguish between wild type and surfactant protein (SP-D) deficient knock-out mice.

description: Periodic mesoporous materials of the type (R'O) 3Si-R-Si(OR') 3 with benzene as an organic bridge and a crystal-like periodicity within the pore walls were functionalized with SO 3H or SO 3 - groups and investigated by small-angle neutron scattering (SANS) with in situ nitrogen adsorption at 77 K. If N 2 is adsorbed in the pores the SANS measurements show a complete matching of all of the diffraction signals that are caused by the long-range ordering of the mesopores in the benzene-PMO, due to the fact that the benzene-PMO walls possess a neutron scattering length density (SLD) similar to that of nitrogen in the condensed state. However, signals at higher q-values (>1 1/Å) are not affected with respect to their SANS intensity, even after complete pore filling, confirming the assumption of a crystal-like periodicity within the PMO material walls due to π-π interactions between the organic bridges. The SLD of pristine benzene-PMO was altered by functionalizing the surface with different amounts of SO3H-groups, using the grafting method. For a low degree of functionalization (0.81 mmol SO 3H·g -1) and/or an inhomogeneous distribution of the SO 3H-groups, the SLD changes only negligibly, and thus, complete contrast matching is still found. However, for higher amounts of SO 3H-groups (1.65 mmol SO 3H·g -1) being present in the mesopores, complete matching of the neutron diffraction signals is no longer observed proving that homogeneously distributed SO 3H-groups on the inner pore walls of the benzene-PMO alter the SLD in a way that it no longer fits to the SLD of the condensed N 2.

description: Моделирование искусственных фитоценозов обеспечивает не только охрану, воспроизводство популяций определенных видов в условиях, которые максимально приближенны к их требованиям, но и сохранение фрагментов природной растительности, в том числе степной. Выявление особенностей структурно-функциональной организации популяций, в частности раритетных, дает возможность прогнозировать не только ее состояние в будущем, но и представление о процессах, которые происходят в экосистеме в целом. Исследованы базовые характеристики (возрастная структура, плотность) интродукционных популяций вида, который в пределах Донбасса редко встречается, но не подлежит охране, – Clematis lathyrifolia Bess. ex Reichenb. в условиях экспериментальной степи в Донецком ботаническом саду. Определена возможность использования изменения некоторых популяционных параметров как индикаторов, отражающих направление развития степных фитоценозов. Установлено, что плотность, возрастной состав популяций C. lathyrifolia могут иметь индикаторное значение, отражают процессы трансформации степных растительных сообществ. Могут быть использованы как биомаркеры направления трансформации степных фитоценозов на плакорных участках (средне-, и хорошо развитые черноземы) в условиях слабой антропогенной нагрузки, как индикатор смены степной растительности лугово-степными и луговыми фитоценозами.

description: We present a 350 micron APEX/SABOCA map of IRAS 05399-0121/SMM 1, which is a dense double-core system in Orion B9. We combined these data with our previous LABOCA 870-micron data. The spatial resolution of the new SABOCA image, ~3400 AU, is about 2.6 times better than provided by LABOCA. We also make use of Spitzer infrared observations to characterise the star-formation activity in the source. The source is filamentary and remains a double-core system on the 3400 AU scale probed here, where the projected separation between IRAS 05399 and SMM 1 is 0.14 pc. The broadband spectral energy distribution of IRAS 05399 suggests that it is near the Stage 0/I borderline. A visual inspection of the Spitzer/IRAC images provides hints of a quadrupolar-like jet morphology around IRAS 05399, supporting the possibility that it is a binary system. The temperature map reveals warm spots towards IRAS 05399 and the southeastern tip of the source. These features are likely to be imprints of protostellar or shock heating, while external heating could be provided by the nearby high-mass star-forming region NGC 2024. A simple analysis suggests that the density profile at the position of SMM 1 has the form ~r^-(2.3_{-0.9}^{+2.2}). The source splitting into two subcores along the long axis can be explained by cylindrical Jeans-type fragmentation but the steepness of the density profile is shallower than what is expected for an isothermal cylinder. The difference between the evolutionary stages of IRAS 05399 (protostellar) and SMM 1 (starless) suggests that the former has experienced a phase of rapid mass accretion, supported by the very long outflow it drives. The protostellar jet from IRAS 05399 might have influenced the nearby core SMM 1.

description: A steady traffic growth has posed a threat to the fatigue safety of existing bridges. Uncertainties in traffic flows add to the challenge of an accurate fatigue safety assessment. This article utilizes a stochastic traffic load model to evaluate the fatigue reliability of orthotropic steel bridge decks. The traffic load model is simulated by site-specific weigh-in-motion measurements. A response surface method is presented to solve the time-consuming problem caused by hotspot stress simulations in the finite element model. Applications of the stochastic traffic load model for probabilistic modeling and fatigue reliability assessment are demonstrated in the case study of a steel box-girder bridge. Numerical results indicate that the growth rate of the gross vehicle weight leads to a rapid decrease of the fatigue reliability in comparison to the traffic volume growth. Even though the traffic volume growth is rapid, the control of overloaded trucks in comparison to the traffic volume is an effective way to ensure the fatigue safety of the steel bridges.

description: We present a conceptually new framework for describing jet evolution in the dense medium produced in ultra-relativistic nucleus-nucleus collisions using perturbative QCD and its implementation into the Monte Carlo event generator JEWEL. The rescattering of hard partons in the medium is modelled by infrared continued pQCD matrix elements supplemented with parton showers. The latter approximate higher order real-emission matrix elements and thus generate medium-induced gluon emissions. The interplay between different emissions is governed by their formation times. The destructive interference between subsequent scattering processes, the non-Abelian version of the Landau-Pomeranchuk-Migdal effect, is also taken into account. In this way the complete radiation pattern is consistently treated in a uniform way. Results obtained within this minimal and theoretically well constrained framework are compared with a variety of experimental data susceptible to jet-quenching effects at both RHIC and the LHC. Overall, a good agreement between data and simulation is found. This new framework also allows to identify and quantify the dominant uncertainties in the simulation, and we show some relevant examples for this.

description: The results of a search for an excited bottom-quark b* in pp collisions at sqrt(s)=7 TeV, using 4.7/fb of data collected by the ATLAS detector at the LHC are presented. In the model studied, a single b*-quark is produced through a chromomagnetic interaction and subsequently decays to a W boson and a top-quark. The search is performed in the dilepton and lepton+jets final states, which are combined to set limits on b*-quark couplings for a range of b*-quark masses. For a benchmark with unit size chromomagnetic and Standard Model-like electroweak b* couplings, b*-quarks with masses less than 870 GeV are excluded at the 95% credibility level.

Surface roughness effect on boundary layer and shock-induced separation on transonic compressor profile

Publisher: name: Zenodo

description: This research was conducted at the transonic wind tunnel in the Institute of Fluid-Flow Machinery, Polish Academy of Science (IMP PAN), in collaboration with Rolls-Royce Deutschland. The primary objective of this study is to experimentally investigate the effects of surface texturing on a fan profile, specifically on the suction side boundary layer in high-speed flows. To simulate the shock boundary layer interaction (SBLI) on the suction side of a typical fan profile, a single-passage test section was designed and manufactured. Various surface textures were analyzed for 100mm chord profiles, with an arithmetic average roughness (Ra) ranging from 0.17μm to 1.48μm, assessed using a 2D Stylus diamond at the Institute of Manufacturing and Materials Technology, Gdansk University of Technology. The research involves profile pressure measurements, high-speed/Schlieren visualization, and LDA boundary layer measurements both upstream and downstream of the passage shockwave.
The results indicated generally slight differences between the presented cases. The probable reason for this is the low roughness heights, which are still within the laminar sub-layer. However, a common characteristic peak at 300Hz was observed. The rough profile (with Ra 1.48) exhibited an unstable and forceful shockwave, noticeable in the low-frequency bandwidth (within the range of 60 to 100Hz), indicating a change in the separation bubble dynamics beneath the shockwave. Additionally, some disturbances were observed in the boundary layer upstream of the shock wave.

description: A three-dimensional meteorological micro-scale model was combined with a forestry windthrow tool to study the risk of urban trees under stormy conditions. The numerical results for an isolated individual tree are compared to general findings from forestry and pulling experiments in the field. It was found that the model is suitable to capture the critical wind speed in the right order of magnitude which causes strong hazards to trees. The new tool was applied to a limited real city environment during storm "Xavier", where significant and extensive tree damage have been observed. A comparison of the numerical results with the observations demonstrates a very reasonable agreement not only for the onset of windthrow but also for the right areal distribution during different phases of the storm.

description: A treatment of conditional clauses from the point of view of such terms as real-unreal conditions or similar is unsatisfactory if the first requirement for the language is that of communication. This essay presents the problem of conditional clauses from the perspective of signification and of the propositions that are expressed by such constructions. Signification is founded on the relation between antecedent and consequence. The final meanings are given by the interaction between the relation on the one hand and context and intentionality of the speaker on the other. The author distinguishes among more general meanings such as wishes or influence, more concrete meanings such as formulations of laws and norms, and rhetorical uses and argumentation. Hypotheses are treated separately from the field of grammar and located in the field of rhetoric.
description: El tratamiento del periodo condicional bajo la optica de terminos como condicionales reales o irreales u otros similares es insuficiente cuando la primera exigencia que se plantea a la lengua es la de la comunicacion. Este trabajo presenta el problema del periodo condicional desde la perspectiva de la significacion y las proposiciones que expresan estas construcciones sintacticas. La significacion es fundamentada en la relacion que se establece entre el antecedente y la consecuencia. Anadiendo la intencionalidad del hablante y el contexto se llega a significados que van desde lo mas generales como deseos o influencia, a los mas concretos como la formulacion de leyes y normas o a los mas retoricos como los usos argumentativos. La hipotesis se saca del plano de la gramatica y se localiza en el de la retorica.

description: The statistics of discovered exoplanets suggest that planets form efficiently. However, there are fundamental unsolved problems, such as excessive inward drift of particles in protoplanetary disks during planet formation. Recent theories invoke dust traps to overcome this problem. We report the detection of a dust trap in the disk around the star Oph IRS 48 using observations from the Atacama Large Millimeter/submillimeter Array (ALMA). The 0.44-millimeter-wavelength continuum map shows high-contrast crescent-shaped emission on one side of the star originating from millimeter-sized grains, whereas both the mid-infrared image (micrometer-sized dust) and the gas traced by the carbon monoxide 6-5 rotational line suggest rings centered on the star. The difference in distribution of big grains versus small grains/gas can be modeled with a vortex-shaped dust trap triggered by a companion.

description: Active high-lift systems of future civil aircraft allow noise reduction and the use of shorter runways. Powering high-lift systems electrically have a strong impact on the design requirements for the electrical power supply of the aircraft. The active high-lift system of the reference aircraft designconsideredinthispaperconsistsofa?exibleleading-edgedevicetogetherwithacombination of boundary-layer suction and Coanda-jet blowing. Electrically driven compressors distributed along the aircraft wings provide the required mass?ow of pressurized air. Their additional loads signi?cantly increase the electric power demand during take-off and landing, which is commonly provided by electric generators attached to the aircraft engines. The focus of the present study is a feasibility assessment of alternative electric power supply concepts to unburden or eliminate the generator coupled to the aircraft engine. For this purpose, two different concepts using either fuel cells or batteries are outlined and evaluated in terms of weight, ef?ciency, and technology availability. The most promising, but least developed alternative to the engine-powered electric generator is the usage of fuel cells. The advantages are high power density and short refueling time, compared to the battery storage concept.

description: The small carpenter bees (genus Ceratina Latreille), carpenter bees (genus Xylocopa
 Latreille) are known to be polylectic and are efficient pollinators of different economically
 important agricultural and horticultural crops. They are cavity nesters. The present study in
 Sundarbans Biosphere Reserve, documents a few nests of cavity nesting bees like Ceratina sp.,
 Xylocopa sp. bees in log of the mangrove plants which were used as fencing in brinjal and bean
 farms. The nesting details include length and width of the nest, number of brood cells and also
 number of larva and adults. The study compared the community structure of bees like species
 richness, diversity, evenness, density etc. in two different kinds of farms, with reference to the
 fencing material used, whether artificial or natural. The results highlighted the importance of
 biofencing in supporting the sustenance of cavity nesting bees and how a small shift to artificial
 fencing items like nylon nets and plastic poles can lead to a local decline in bee populations
 negatively impacting the pollination service. Farmer surveys gauging the perceptions on
 farming practices indicated the dire need to create awareness on the value of pollinators,
 especially the non-apis wild bees.

description: We present 32 epochs of optical (3300-9700 Å) spectrophotometric observations of the nearby quintessential "normal" type Ia supernova (SN Ia) SN 2011fe in the galaxy M101, extending from -15 to +97 d with respect to B-band maximum, obtained by the Nearby Supernova Factory collaboration. SN 2011fe is the closest (μ= 29.04) and brightest (Bmax = 9.94 mag) SN Ia observed since the advent of modern large scale programs for the intensive periodic followup of supernovae. Both synthetic light curve measurements and spectral feature analysis attest to the normality of SN 2011fe. There is very little evidence for reddening in its host galaxy. The homogeneous calibration, intensive time sampling, and high signal-to-noise ratio of the data set make it unique. Thus it is ideal for studying the physics of SN Ia explosions in detail, and for furthering the use of SNe Ia as standardizable candles for cosmology. Several such applications are shown, from the creation of a bolometric light curve and measurement of the 56Ni mass, to the simulation of detection thresholds for unburned carbon, direct comparisons with other SNe Ia, and existing spectral templates.

title: On Myth & Music, Legend & Landscape, Science, Stars, & Story; A Portfolio of Compositions: An Animist Aesthetic Argument on Symbolist Sound-Synergies, with Musings on Messiaen and the Taoism of Takemitzu, in the work of Mulvany.

description:
The accompanying portfolio contains eight major works for disparate forces: Brú na Sídhe is a work for Large Orchestra; Bog Bodies is a work commissioned for a heterogenous Quintet; Gáeth Ard Úar is a work written for a Solo Bass/Contrabass Clarinet in B-flat; a Piano Trio, SzyzygyS, follows; a work entitled Blackwater is written for Solo Guitar; a diptych, named Sigil, written for a Dectet of Harp and Vibraphone with double String Quartet, follows; then, O Unworn World for a ten part Choral ensemble is presented as a meditation on a poem by Patrick Kavanagh; and, the last of the works in the portfolio, is a String Quartet entitled Wodwo. These pieces are conceived using an aesthetic guide provided by two substantially different composers: Tōru Takemitsu and Olivier Messiaen. The connection with these composers is explored in a chapter entitled the Aesthetic Review, Chapter One; and, indeed, throughout the commentaries provided in the subsequent chapters dealing with each of the works in the order stated. It is noted that, while these composers provide a guide to the formulation and execution, and even the subject matter, of ideas in music, it is not the case that the music will sound in any way similar to either of these composers. The divergent techniques of composition described within are substantiated with reference to these composers, and fall into three broadly defined categories: the Constructivist, the Impressionist, and the Deductivist approaches to style. The works also contain a similar approach to the subject matter of the inspiration. A thread of Pagan Spirituality and Mythology can be traced through all of the works, to varying degrees. They contain, in addition, a preponderance on duality as a concept; the duality of Science and Natural Spirituality; the duality of defined and undefined sounds; and the duality of composer and performer. With these works, the composer wishes to demonstrate a mastery of compositional techniques and a thorough and methodical approach to the realisation of a conceptual framework.

Comb-like models for transport along spiny dendrites

description: We suggest a modification of a comb model to describe anomalous transport in spiny dendrites. Geometry of the comb structure consisting of a one-dimensional backbone and lateral branches makes it possible to describe anomalous diffusion, where dynamics inside fingers corresponds to spines, while the backbone describes diffusion along dendrites. The presented analysis establishes that the fractional dynamics in spiny dendrites is controlled by fractal geometry of the comb structure and fractional kinetics inside the spines. Our results show that the transport along spiny dendrites is subdiffusive and depends on the density of spines in agreement with recent experiments.

Parametrization of coronal heating: spatial distribution and observable consequences

description: We investigate the difference in the spatial distribution of the energy input for parametrizations of different mechanisms to heat the corona of the Sun and possible impacts on the coronal emission. We use a 3D MHD model of a solar active region as a reference and compare the Ohmic-type heating in this model to parametrizations for alternating current (AC) and direct current (DC) heating models, in particular, we use Alfven wave and MHD turbulence heating. We extract the quantities needed for these two parametrizations from the reference model and investigate the spatial distribution of the heat input in all three cases, globally and along individual field lines. To study differences in the resulting coronal emission we employ 1D loop models with a prescribed heat input based on the heating rate we extracted along a bundle of field lines. On average, all heating implementations show a roughly drop of the heating rate with height. This also holds for individual field lines. While all mechanism show a concentration of the energy input towards the low parts of the atmosphere, for individual field lines the concentration towards the footpoints is much stronger for the DC mechanisms than for the Alfven wave AC case. In contrast, the AC model gives a stronger concentration of the emission towards the footpoints. This is because the more homogeneous distribution of the energy input leads to higher coronal temperatures and a more extended transition region. The significant difference in the concentration of the heat input towards the foot points for the AC and DC mechanisms, and the pointed difference in the spatial distribution of the coronal emission for these cases shows that the two mechanisms should be discriminable by observations. Before drawing final conclusions, these parametrizations should be implemented in new 3D models in a more self-consistent way.
