description: Discrete unified gas-kinetic scheme (DUGKS) is a multi-scale numerical method for flows from continuum limit to free molecular limit, and is especially suitable for the simulation of multi-scale flows, benefiting from its multi-scale property. To reduce integration error of the DUGKS and ensure the conservation property of the collision term in isothermal flow simulations, a Conserved-DUGKS (C-DUGKS) is proposed. On the other hand, both DUGKS and C-DUGKS adopt Cartesian-type discrete velocity space, in which Gaussian and Newton-Cotes numerical quadrature are used for calculating the macroscopic physical variables in low speed and high speed flows, respectively. While, the Cartesian-type discrete velocity space leads to huge computational cost and memory demand. In this paper, the isothermal C-DUGKS is extended to the non-isothermal case by adopting coupled mass and inertial energy distribution functions. Moreover, since the unstructured mesh, such as the triangular mesh in two dimensional case, is more flexible than the structured Cartesian mesh, it is introduced to the discrete velocity space of C-DUGKS, such that more discrete velocity points can be arranged in the velocity regions that enclose large number of molecules, and only a few discrete velocity points need to be arranged in the velocity regions with small amount of molecules in it. By using the unstructured discrete velocity space, the computational efficiency of C-DUGKS is significantly increased. A series of numerical tests in a wide range of Knudsen numbers, such as the Couette flow, lid-driven cavity flow, two-dimensional rarefied Riemann problem and the supersonic cylinder flows, are carried out to examine the validity and efficiency of the present method.

description: In-situ sorbent amendment is a relatively low-cost, low-impact approach for remediation of soil contaminated with heavy metals (HMs), and thus is considered a way to be favored in developing countries. In this study, materials of non-hazardous, alkaline agronomic and industrial by-products were used as sorbents to explore their capacity of in situ immobilization of multiple HMs in mining-impacted arable soil. These sorbents included fly ash (FA), biochar (BC) and apatite (AP) and they were implemented with varying ratios of combinations. Results of soil microcosm tests showed that after incubation for 90 days, concentrations of Pb, Zn, and Cd in their exchangeable forms determined by a sequential extraction method significantly decreased in amended soils, as opposed to the unamended control. Of the five sets of amendments, the composite of FA, BC, and AP resulted in the maximum reduction (up to 80%) in the mobility of Pb, Zn, and Cd in soils. The mechanisms underlying the immobilization of HMs in amended soils might involve processes of surface precipitation, ion exchange and complexation, in which the physicochemical properties of sorbent materials played an important role. The immobilization efficacy of sorbent amendments on HMs in soil was further supported by pot experiments in which significant inhibition of HM accumulation in the belowground and aboveground tissues of maize was observed after 50-day cultivation in amended soils as compared with control soil. Together, these results suggest that the application of cost-saving and environmentally friendly materials derived from wastes as sorbents to remediate soils contaminated with multiple HMs is promising for developing countries like Vietnam.

description: What happens when an organization that has been collecting data closes shop? Has their data been archived? Has it been disseminated to the academic community? Has all the metadata been kept with its associated data? This talk illustrates a case study of a data rescue in a Data Centre. We were informed that there was a series of datasets that needed a home because the government funding for this organization was withdrawn. The talk will include: the background of the Centre for Research in Canada (CRIC); how the rescue mission came about; the rescue mission itself; and the importance of data rescue. Then the question of whose responsibility it is to keep data alive will be discussed.

description: Rapid changes on the market, such as rising of the prices of energy and raw materials, the emergence of new competitors, impossibility of collection of receivables, impossibility of settling obligations to suppliers and business partners are significant difficulties that company must solve to for further survival, growth and development. In front of the management there are serious business actions which execution will achieve the desired goal or will lead company to the loss and, because of difficult business conditions, very fast to the bankruptcy. For production companies it is very important to analyze the changes that occur in the field of income and expenses. Adequate analysis can determine the change of the position of economic success of the enterprise in observed period. The results of these analysis show the economic efficiency of business, so as the elements on which management should focus its efforts. The analysis was conducted on domestic company on the basis of data obtained from official financial reports.

description: We study the quantum Zeno effect in the case of indirect measurement, where the detector does not interact directly with the unstable system. Expanding on the model of Koshino and Shimizu [Phys. Rev. Lett., 92, 030401, (2004)] we consider a realistic Hamiltonian for the detector with a finite bandwidth. We also take explicitly into account the position, the dimensions and the uncertainty in the measurement of the detector. Our results show that the quantum Zeno effect is not expected to occur, except for the unphysical case where the detector and the unstable system overlap.

description: In making an investment in an instrument, investors need to know how much risk they are taking. They have to assess whether the instrument is properly priced, or whether they are getting sufficient returns for the chance they are taking. The CAPM can be defined as ‘a mathematical model that seeks to explain the relationship between risk and return in a rational equilibrium market’ and ‘ an economic model for valuing stocks, securities, derivatives and/or assets by relating risk and expected return’. For this study, CAPM is tested using a basket of 20 randomly selected stocks from the Dow Jones Industrial index, a U.S. stock market index consisting of 30 large, industrial companies. The coverage period is from January 1997 to December 2006, which is prior to the credit crisis that engulfed the financial world back in 2007, to enable us to take a much deeper look at the CAPM. Inclusion of the post-crisis data could distort the resulting models, consequently leading to a biased evaluation of the model. The chosen proxy for the risk-free rate was the monthly rate of the 3-month Treasury Bill issued by the Treasury Department of the U.S. This would indeed be the most appropriate proxy for a risk-free rate as the U.S. is the leading economy of the world and most, if not all, of the debt instruments issued by its government are considered ‘risk-free’.

description: Business communication means both giving and receiving business information to achieve specific business objectives and concrete results. Any transfer of business information is also the transfer of feelings about any information we have. When we learn to listen to the feelings and needs of other people, we will achieve quality relationships. To achieve non-violent business communication, it is necessary to accept a partner or a party with all his or her virtues and vices. Non-violent business communication is a higher level of business culture based on honesty and clarity of the participants in communication, the sender trying to convey a message to volunteer to receive from the recipient, in an effort of the participants in the communication to stay human.

description: We report on simultaneous sub-second optical and X-ray timing observations of the low mass X-ray binary black hole candidate MAXI J1820+070. The bright 2018 outburst rise allowed simultaneous photometry in five optical bands ($ugriz_s$) with HiPERCAM/GTC (Optical) at frame rates over 100 Hz, together with NICER/ISS observations (X-rays). Intense (factor of two) red flaring activity in the optical is seen over a broad range of timescales down to $\sim$10 ms. Cross-correlating the bands reveals a prominent anti-correlation on timescales of $\sim$seconds, and a narrow sub-second correlation at a lag of $\approx$+165 ms (optical lagging X-rays). This lag increases with optical wavelength, and is approximately constant over Fourier frequencies of $\sim$0.3-10 Hz. These features are consistent with an origin in the inner accretion flow and jet base within $\sim$5000 Gravitational radii. An additional $\sim$+5 s lag feature may be ascribable to disc reprocessing. MAXI J1820+070 is the third black hole transient to display a clear $\sim$0.1s optical lag, which may be common feature in such objects. The sub-second lag $variation$ with wavelength is novel, and may allow constraints on internal shock jet stratification models.

Publisher: name: Zenodo
Year: 2010

description: Recently the Finnish Social Science Data Archive (FSD) has taken part in a pilot project by the National Digital Library which intends to develop organisations' readiness to "make the transition into an electronic operating environment". The project conducted a series of surveys in late 2009 measuring the organisations' data management quality and maturity. At FSD we would want to believe that we already operate electronically. This presentation summarises the findings of the report. The Digital Library project aims to create a centralised long-term preservation solution for the digital cultural objects, and later, for research data too. The project participants vary from large national institutions to regional museums and private archives. Finding a single solution that would ensure long-term preservation and dissemination will be a challenge. Sharing of competence, building partnerships and monitoring international development are crucial for success. This presentation seeks to answer the following questions: How does a national data archive do when compared to libraries, traditional archives and museums ("LAMs")? What could be the mutual benefits of actively working with the LAMs in the field of long-term preservation? Metadata used in and by the LAMs differ notably from research data documentation. How to approach other metadata formats than DDI?

description: Tidal radii of remote globular clusters (R_{GC}>= 35 kpc) are used to provide constraints of the mass profile of the Milky Way galaxy that are independent of kinematic data. The available data are consistent with the profile of an isothermal sphere with circular velocity V_c = 220 +/- 40 km/s in the radial range 35 kpc < R_{GC} < 100 kpc, in good agreement with all recent estimates. The more robust constraint at large distances from the galactic center is provided by NGC 2419, yelding an enclosed mass of ~ 1.3 (+2.9/-1.0) * 10**12 M_{sun} at R_{GC}= 90 kpc.

description: Traffic sign recognition feature is widely employed in industry today by researchers working in artificial intelligence and machine learning fields targeted to create an autonomous driving assistance system. This will help the driver’s human eye specifically the maneuvering capabilities which can’t be presumed to be consistent for high accuracy for all weather condition challenges. Road safety, in particular, hinges on the accurate human eye perception of road signs. This research paper illustrates a novel approach for traffic image classification using Deep Learning Model to distinguish the different classes of traffic signs using data augmentation offered by Keras Deep Learning Library for shifting traffic signs images. This will help us recreate a dataset similar to images captured during bad climatic, foggy or windy conditions or badly captured images due to fast moving cars with limitation in camera angles from roads. We will be introducing these pictures on a state-of-the-art architectures pre-trained transfer learning model such as VGG19, ALEXNET and RESNET50 as they provide better accuracy and operational speed to create a best fit model. The model generated a 98% accuracy in German sign recognition benchmark.

description: The concept of biased data is well known and its practical applications range from social sciences and biology to economics and quality control. These observations arise when a sampling procedure chooses an observation with probability that depends on the value of the observation. This is an interesting sampling procedure because it favors some observations and neglects others. It is known that biasing does not change rates of nonparametric density estimation, but no results are available about sharp constants. This article presents asymptotic results on sharp minimax density estimation. In particular, a coefficient of difficulty is introduced that shows the relationship between sample sizes of direct and biased samples that imply the same accuracy of estimation. The notion of the restricted local minimax, where a low-frequency part of the estimated density is known, is introduced; it sheds new light on the phenomenon of nonparametric superefficiency. Results of a numerical study are presented.

Barriers to Data Sharing: New Evidence from a US Survey

Year: 2010

description: Recent studies demonstrate that the majority of social science data is not preserved or shared through social science data archives and other formal archival arrangements. This motivates further investigation about the various ways researchers share their data (including more "informal" data sharing) and the factors that underlie their data sharing behavior. We developed a survey to collect information from principal investigators (PIs) of federally funded research grants in the US about their experiences with data sharing (n=1,021). We also collected information about various factors that might be related to data sharing behavior including: normative data sharing practices in their discipline, perceived barriers to data sharing, rank/tenure, institutional type, gender and so on. We find that while only 12% of the PIs have archived their data, 45% have shared their data outside the immediate research team. Being in a discipline that favors data sharing is positively associated with the likelihood that a PI shares his or her research data. Perceived barriers to data sharing reduce the likelihood one shares data. Other factors associated with data sharing include rank/tenure status and duration of the grant. Implications for data archives are also discussed.

description: Creating a brand involves a process in which many characteristics of a brand are defined, resulting in the brand being accepted and preferred by the target consumer group. Attributes must differentiate the brand from competitors’ brands, which by their diversity influence consumer’s senses. Through the senses people as individuals become aware of companies, products and brands, making a particular perception. Each sense has certain functions and marketing potentials, which in synergy achieve full experience of brand identity. When it comes to food buying behavior, preference of a consumer for a particular brand is not always its biochemical value of health probity. Psycho-physical factors play major role with the consumers - positive sensory stimulation, which is primarily affected by the pleasant smell and taste (aroma), an attractive natural color and appearance, freshness, texture and special nutritive value.

Reproducibility of Computational Results: Opening Code and Data
Creators: name: Stodden, Victoria
Publisher: name: Zenodo
Year: 2010

description: Scientific computation is emerging as absolutely central to the scientific method, but the prevalence of very relaxed practices is leading to a credibility crisis. Reproducible computational research, in which all details of computations — code and data — are made conveniently available to others, is a necessary response to this crisis. Questions emerge regarding scientists' incentives and motivations to share. This talk presents results from a survey of computational scientists to determine the factors that facilitate code and data sharing and those that create barriers. One major result finds that sharing is done for reasons other than direct personal gain, but when scientists choose not to reveal data or code this is due to perceived personal impact. A second major finding is the prominence of Intellectual Property concerns with regard to not sharing code and data. Solutions to the various barriers are discussed, including how the "Reproducible Research Standard" (Stodden 2008), which proposes a licensing structure consonant with scientific norms, can thus encourage open sharing in scientific research.

description: (Abridged) Our aim is to identify analogues of gas giant planets, as companions at wide separations of very young stars. To identify these objects, we cross correlated the Visible and Infrared Survey Telescope for Astronomy (VISTA) Hemisphere Survey (VHS) and the United Kingdom Infrared Telescope Infrared Deep Sky Survey Galactic Clusters Survey (UKIDSS GCS) catalogues to search for common proper motion companions to 1195 already known members of Upper Scorpius (USco; age $\sim$5-10 Myr, distance $\sim$145 pc). We present the discovery and spectroscopic characterisation of two very wide substellar companions of two early-M stars in Upper Scorpius: USco1621 B and USco1556 B. We obtained optical and near-infrared low-resolution spectroscopy of the candidates to characterise their spectral energy distribution and confirm their membership to the association. We also acquired adaptive optics images of the primaries and secondaries to search for signs of binarity and close companions. We determined a spectral type of M8.5 in the optical for both companions, along with L0 and L0.5 in the near-infrared for USco1621 B and USco1556 B, respectively. The spectra of the two companions show evident markers of youth. The comparison with theoretical evolutionary models gives estimated masses of 0.015$\pm$0.002 and 0.014$\pm$0.002 M$_{\odot}$, with temperatures of 2270$\pm$90 and 2240$\pm$100 K, respectively. The physical separations between the components of both systems are 2880$\pm$20 and 3500$\pm$40 AU for USco1621 and USco1556 systems, respectively. We did not find any additional close companion in the adaptive optics images. The probability that the two secondaries are physically bound to their respective primaries, and not chance alignments of USco members, is 86%, and the probability that none of them are physically related is 1.0%.

description: We have written a Fortran programme BCVEGPY, which is an event generator for the hadronic production of the $B_c$ meson through the dominant hard subprocess $gg\to B_c(B_c^*) +b+\bar{c}$. To achieve a compact programme, we have written the amplitude of the subprocess with the particle helicity technique and made it as symmetric as possible, by decomposing the gluon self couplings and then applying the symmetries. To check the programme, various cross sections of the subprocess have been computed numerically and compared with those in the literature. BCVEGPY is written in a PYTHIA-compatible format, thus it is easy to implement in PYTHIA.

description: Hot cavity resonant ionization laser ion sources (RILIS) provide a multitude of radioactive ion beams with high ionization efficiency and element selective ionization. However, in hot cavity RILIS there still remains isobaric contaminations in the extracted beam from surface ionized species. An ion guide-laser ion source (IG-LIS) has been implemented that decouples the hot isotope production region from the laser ionization volume. A number of IG-LIS runs have been conducted to provide isobar free radioactive ion beams for experiments. Isobar suppression of up to 106 has been achieved, however, IG-LIS still suffers from an intensity loss of 50-100X as compared to hot cavity RILIS. Operating parameters for IG-LIS are being optimized and design improvements are being implemented into the prototype for robust and efficient on-line operation. Recent SIMION ion optics simulation results and the ongoing development status of the IG-LIS are presented.

But often there are strings attached to the access, usage and reporting of data, even if the data are "free." Researchers may compile a dataset but what rights do they have for the use of those data? This paper will outline some of the issues and considerations of which data professionals in the social science need to be aware. Copyright, licensing, redistribution and intellectual property rights are now important issues that data users, and those who support them, need to understand early on in the research process.

description: This paper uses supervised learning, random search and deep reinforcement learning (DRL) methods to control large signalized intersection networks. The traffic model is Cellular Automaton rule 184, which has been shown to be a parameter-free representation of traffic flow, and is the most efficient implementation of the Kinematic Wave model with triangular fundamental diagram. We are interested in the steady-state performance of the system, both spatially and temporally: we consider a homogeneous grid network inscribed on a torus, which makes the network boundary-free, and drivers choose random routes. As a benchmark we use the longest-queue-first (LQF) greedy algorithm. We find that: (i) a policy trained with supervised learning with only two examples outperforms LQF, (ii) random search is able to generate near-optimal policies, (iii) the prevailing average network occupancy during training is the major determinant of the effectiveness of DRL policies. When trained under free-flow conditions one obtains DRL policies that are optimal for all traffic conditions, but this performance deteriorates as the occupancy during training increases. For occupancies > 75% during training, DRL policies perform very poorly for all traffic conditions, which means that DRL methods cannot learn under highly congested conditions. We conjecture that DRL's inability to learn under congestion might be explained by a property of urban networks found here, whereby even a very bad policy produces an intersection throughput higher than downstream capacity. This means that the actual throughput tends to be independent of the policy. Our findings imply that it is advisable for current DRL methods in the literature to discard any congested data when training, and that doing this will improve their performance under all traffic conditions.

Undetermined genus and species
Material examined: a single small columnal (OPH212).
Description: columnal of heptagonal facet with radiate crenulae poorly preserved (Fig. 6F), diameter 0.75 mm, height 0.50 mm.
Remarks: Heptagonal shape, or 7 crenular units on articular facets, is a frequent condition in hyocrinid columnals (Mironov & Sorokina, 1998; Roux & Lambert, 2011) but unknown in other extant stalked crinoid families. Moreover, symmetry 6–7 is more common in juvenile stalks and tends to disappear during growth by adjunction of new crenular units and generalization of circular articular facets. The small size of this columnal suggests that it belongs to a juvenile specimen which cannot be attributed at the genus rank.

description: This article examines density estimation by combining a parametric approach with a nonparametric factor. The plug-in parametric estimator is seen as a crude estimator of the true density and is adjusted by a nonparametric factor. The nonparametric factor is derived by a criterion called local L_2-fitting. A class of estimators that have multiplicative adjustment is provided, including estimators proposed by several authors as special cases, and the asymptotic theories are developed. Theoretical comparison reveals that the estimators in this class are better than, or at least competitive with, the traditional kernel estimator in a broad class of densities. The asymptotically best estimator in this class can be obtained from the elegant feature of the bias function.

description: Both in the design and deployment of blockchain solutions many performance-impacting configuration choices need to be made. We introduce BlockSim, a framework and software tool to build and simulate discrete-event dynamic systems models for blockchain systems. BlockSim is designed to support the analysis of a large variety of blockchains and blockchain deployments as well as a wide set of analysis questions. At the core of BlockSim is a Base Model, which contains the main model constructs common across various blockchain systems organized in three abstraction layers (network, consensus and incentives layer). The Base Model is usable for a wide variety of blockchain systems and can be extended easily to include system or deployment particulars. The BlockSim software tool provides a simulator that implements the Base Model in Python. This paper describes the Base Model, the simulator implementation, and the application of BlockSim to Bitcoin, Ethereum and other consensus algorithms. We validate BlockSim simulation results by comparison with performance results from actual systems and from other studies in the literature. We close the paper by a BlockSim simulation study of the impact of uncle blocks rewards on mining decentralization, for a variety of blockchain configurations.

description: A key theme for the UK's Survey Question Bank (SQB) (www.surveyney.ac.uk/sqb) - the successor to the former Question Bank (Qb) run from the University of Surrey - is the push to build an online community of users. The SQB is delivering a range of strategies across the 'traditional-through-innovative' spectrum to get users involved in the service. Traditional features include the 'top-down' delivery of news via mailing lists and newsfeeds. The service has also used twitter (www.twitter.com/surveynetacuk) and Methodspace (www.methodspace.com/groups/surveyresourcesnetwork) to encourage greater 'bottom-up' activity. Most innovatively, the service will soon introduce an interactive element to its forthcoming survey question database, allowing users to comment on survey questions.nbsp;Later in 2010, the SQB will be investigating how it might house a 'grey literature' repository so that users might find a home for their previously unpublished resources/tools, papers, presentations etc. This presentation will describe these strategies and review early successes and failures.

description: The transformation of dilapidated houses in rural areas is not only a livelihood project related to the broad masses of rural people, but also a major project to win the battle against poverty. Luquan Yi and Miao Autonomous County, Yunnan Province, located in the high mountain and gorge area along Jinsha River, is one of the key counties of poverty alleviation and development with a wide range of poverty and a deep degree of poverty. The incidence of poverty is 22.21%. Housing security is the focus, difficulty and emphasis of poverty alleviation in this county, the number of dilapidated houses is large, the type is complex, the transformation is difficult, and the implementation cost is high. Since the beginning of 2017, Luquan County has faced difficulties, explored in depth, pioneered and innovated, and completed the renovation of 54801 dilapidated houses in an all-round way. It created a road full of characteristics and effectiveness of rural dilapidated housing transformation, and explored a set of effective scientific identification and accurate transformation models for rural dilapidated housing worthy of reference and promotion. Successful renovation of dilapidated houses, combined with industrial poverty alleviation, education poverty alleviation, health poverty alleviation and other accurate poverty alleviation measures, have made Luquan County win a decisive victory in the fight against poverty. By the end of December 2018, the incidence of poverty in the county had dropped to 0.54 percent, and 115 poor villages (including 83 extremely poor villages) had successfully shaken off poverty.This paper analyzes and summarizes the concrete methods, main effects, characteristics and bright spots, successful experience, and reference significance of the scientific identification and precise transformation mode of rural dilapidated houses in this county, so as to provide a necessary reference for the transformation of rural dilapidated houses in Yunnan Province and even poor counties in similar provinces (cities and districts).

subject: Britain, Cobbett, Rural poverty

description: In the late 18th and 19th centuries, the problem of poverty in the English countryside was relatively serious. The radical Cobbett pays attention to the rural society and elaborates on the tax burden, the polarization of rural society and the poverty of agricultural workers in a series of works, not only promoting the parliamentary reforms in 1832 but also arousing widespread concern on rural poverty from the society at that time. By drawing on the research of the famous radical Cobbett from domestic and foreign academic circles, based on many original materials such as newspapers, books and pamphlets in the 19th century, this article combs Cobbett’s account of rural poverty in modern Britain and analyzes its value.
