description: Learning to see through data is central to contemporary forms of algorithmic knowledge production. While often represented as a mechanical application of rules, making algorithms work with data requires a great deal of situated work. This paper examines how the often-divergent demands of mechanization and discretion manifest in data analytic learning environments. Drawing on research in CSCW and the social sciences, and ethnographic fieldwork in two data learning environments, we show how an algorithm's application is seen sometimes as a mechanical sequence of rules and at other times as an array of situated decisions. Casting data analytics as a rule-based (rather than rule-bound) practice, we show that effective data vision requires would-be analysts to straddle the competing demands of formal abstraction and empirical contingency. We conclude by discussing how the notion of data vision can help better leverage the role of human work in data analytic learning, research, and practice.
Response-adaptive designs in clinical trials for targeting the best treatment : An overview

Publisher: name: American University
Year: 2023

description: Response-adaptive designs are increasingly being implemented in clinical trials, particularly early phase trials, and they have increasingly stimulated the work of researchers. This paper reviews a particular class of response-adaptive designs, which have a different property from the most adaptive designs in literature. These are response-adaptive designs targeting asymptotically the superior response, that is, treating with the superior treatment with prob- ability converging to one. The model underlying such designs is a randomly reinforced urn. In the context of clinical trials, this property is particularly attractive from an ethical point of view. This overview starts from the early paper of [8] until the recent work by [9].

description: This paper introduces and formalizes the Fraction Growth Conjecture (Cohoes–Erdős Bound), which establishes a sublinear bound on the number of unique denominators in optimal unit fraction decompositions. The conjecture proposes that as the denominator of a fraction increases, the number of terms required in its minimal decomposition grows at most logarithmically.

The paper provides rigorous theoretical justification using asymptotic analysis, additive number theory, and refinements to classical divisor function estimates, particularly improving upon Tenenbaum’s results. Computational validation up to ten thousand confirms that the number of unique denominators remains sublinear, supporting the conjecture. Additionally, connections to Farey sequences, Dirichlet divisor bounds, and Diophantine approximation are explored, along with broader implications for cryptography, combinatorial optimization, and computational number theory.

This work advances our understanding of unit fraction growth constraints and offers a novel refinement of classical asymptotic divisor estimates.

description: The trustworthiness of data science systems in applied and real-world settings emerges from the resolution of specific tensions through situated, pragmatic, and ongoing forms of work. Drawing on research in CSCW, critical data studies, and history and sociology of science, and six months of immersive ethnographic fieldwork with a corporate data science team, we describe four common tensions in applied data science work: (un)equivocal numbers, (counter)intuitive knowledge, (in)credible data, and (in)scrutable models. We show how organizational actors establish and re-negotiate trust under messy and uncertain analytic conditions through practices of skepticism, assessment, and credibility. Highlighting the collaborative and heterogeneous nature of real-world data science, we show how the management of trust in applied corporate data science settings depends not only on pre-processing and quantification, but also on negotiation and translation. We conclude by discussing the implications of our findings for data science research and practice, both within and beyond CSCW.

description: The marketing production interface is steeped in economic theory, but the principles integrating marketing and management have only recently been applied to the farm problem by extension economists. Further, past research mostly examined marketing or production problems separately. Complexity of issues and a price stabilizing farm policy nullified the need to examine these relationships and to integrate them into an extension program. In this paper the need for an integrated farm management/marketing (MM) program is examined. In this context, economic theory is briefly reviewed, reasons for the prior separation of MM programming for grain and livestock farmers are discussed, and the current interest in and the components of an integrated MM program are reviewed. A simple prescription for developing an integrated MM program is not provided in this paper. Instead, some of the issues are identified.

Long Range Hops and the Pair Annihilation Reaction A+A->0: Renormalization Group and Simulation

Year: 2003
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: A simple example of a non-equilibrium system for which fluctuations are important is a system of particles which diffuse and may annihilate in pairs on contact. The renormalization group can be used to calculate the time dependence of the density of particles, and provides both an exact value for the exponent governing the decay of particles and an epsilon-expansion for the amplitude of this power law. When the diffusion is anomalous, as when the particles perform Levy flights, the critical dimension depends continuously on the control parameter for the Levy distribution. The epsilon-expansion can then become an expansion in a small parameter. We present a renormalization group calculation and compare these results with those of a simulation.

description: We have performed a fully three-dimensional general relativistic magnetohydrodynamic (GRMHD) simulation of jet formation from a thin accretion disk around a Schwarzschild black hole with a free-falling corona. The initial simulation results show that a bipolar jet (velocity nearly 0.3c) is created as shown by previous two-dimensional axisymmetric simulations with mirror symmetry at the equator. The 3-D simulation ran over one hundred light-crossing time units which is considerably longer than the previous simulations. We show that the jet is initially formed as predicted due in part to magnetic pressure from the twisting the initially uniform magnetic field and from gas pressure associated with shock formation in the region around r = 3r_S. At later times, the accretion disk becomes thick and the jet fades resulting in a wind that is ejected from the surface of the thickened (torus-like) disk. It should be noted that no streaming matter from a donor is included at the outer boundary in the simulation (an isolated black hole not binary black hole). The wind flows outwards with a wider angle than the initial jet. The widening of the jet is consistent with the outward moving torsional Alfven waves (TAWs). This evolution of disk-jet coupling suggests that the jet fades with a thickened accretion disk due to the lack of streaming material from an accompanying star.

Up-and-Down Procedures for Approximating Optimal Designs Using Person-Response Functions

description: Algorithms developed for item selection in computerized adaptive testing are exclusively from the item response theory perspective, where responses are examined at the item level. They are limited when all item characteristics are not readily known. This paper illustrates an item selection algorithm using person response functions. When targeting a single percentile, median difficulty level can be an estimate of the person’s ability level. Often however, estimating more than one percentile or the entire person response function is desirable. This study considered optimal designs that either minimize the variance of one percentile estimate or a function of the variance-covariance ellipse jointly for all parameter estimates. Due to the problem that an optimal design for nonlinear models depends on unknown parameters, sequential up-and-down designs for approximating optimal designs are considered. Examples are provided to illustrate the efficiency of the procedures.

description: In a phase I clinical trial, we are interested in finding a dose J-L that will produce toxicity at an acceptable probability level r in the target population. In this paper, we investigate different estimators of the target dose 1-l to be used with the up-and-down Biased Coin Design (BCD) introduced by Durham and Flournoy (1994). These estimators of 1-l are derived using isotonic regression, maximum likelihood, weighted lea.c:;t squares and the simple empirical mean. Given a vector of probability of toxicity at the different doses,we show how to derive the exact distribution of these (and many other) estimators in the BCD setting. However, due to computational limitations, for modest samples (n > 15) the exact method becomes infeasible and bootstrap methods are used. A modified isotonic regression estimate is shown to perform very well, in terms of mean square error (MSE) and average time to converge, in all the scenarios we have studied. Key Words: Up-and-down design, isotonic regression, sequential estimation, quantal estimation, logistic regression, experimental design.

description: We have studied nodal tunneling into YBa2Cu3O7-x (YBCO) films under magnetic fields. The films' orientation was such that the CuO2 planes were perpendicular to the surface with the a and b axis at 450 form the normal. The magnetic field was applied parallel to the surface and perpendicular to the CuO2 planes. The Zero Bias Conductance Peak (ZBCP) characteristic of nodal tunneling splits under the effect of surface currents produced by the applied fields. Measuring this splitting under different field conditions, zero field cooled and field cooled, reveals that these currents have different origins. By comparing the field cooled ZBCP splitting to that taken in decreasing fields we deduce a value of the Bean critical current superfluid velocity, and calculate a Bean critical current density of up to 3*10^7 A/cm2 at low temperatures. This tunneling method for the determination of critical currents under magnetic fields has serious advantages over the conventional one, as it avoids having to make high current contacts to the sample.

Parallel reduction in expression, but no loss of functional constraint, in two opsin paralogs within cave populations of Gammarus minus (Crustacea : Amphipoda)

description: Background: Gammarus minus, a freshwater amphipod living in the cave and surface streams in the eastern USA, is a premier candidate for studying the evolution of troglomorphic traits such as pigmentation loss, elongated appendages, and reduced eyes. In G. minus, multiple pairs of genetically related, physically proximate cave and surface populations exist which exhibit a high degree of intraspecific morphological divergence. The morphology, ecology, and genetic structure of these sister populations are well characterized, yet the genetic basis of their morphological divergence remains unknown. Results: We used degenerate PCR primers designed to amplify opsin genes within the subphylum Crustacea and discovered two distinct opsin paralogs (average inter-paralog protein divergence ≈ 20%) in the genome of three independently derived pairs of G. minus cave and surface populations. Both opsin paralogs were found to be related to other crustacean middle wavelength sensitive opsins. Low levels of nucleotide sequence variation (< 1% within populations) were detected in both opsin genes, regardless of habitat, and dN/dS ratios did not indicate a relaxation of functional constraint in the cave populations with reduced or absent eyes. Maximum likelihood analyses using codon-based models also did not detect a relaxation of functional constraint in the cave lineages. We quantified expression level of both opsin genes and found that the expression of both paralogs was significantly reduced in all three cave populations relative to their sister surface populations. Conclusions: The concordantly lowered expression level of both opsin genes in cave populations of G. minus compared to sister surface populations, combined with evidence for persistent purifying selection in the cave populations, is consistent with an unspecified pleiotropic function of opsin proteins. Our results indicate that phototransduction proteins such as opsins may have retained their function in cave-adapted organisms because they may play a pleiotropic role in other important processes that are unrelated to vision.

description: In the past decade, technological advancements have led to changes in the economy with important implications for the strategic management of new ventures. In this paper, we argue that the dynamics of competition, success, and failure for new ventures have been significantly altered by the convergence of electronic technologies and the growing importance of knowledge- based assets. We proceed from the traditional argument that relates first-mover advantage positively and liabilities of newness negatively to entrepreneurial success. The extremely high failure rate of new firms suggests that traditional startups have typically been overwhelmed by liabilities of newness. We then argue that two features of firms competing in the new economy – knowledge-based assets and “virtual embeddedness” – work to diminish the effects of the liabilities of newness and increase returns to first movers, consequently increasing the probability of success for pioneering new ventures.

Factors Influencing Female Entrepreneurship in India

description: Women’s entrepreneurship, whilst increasing in size and quality across the world, still lags behind in India where many of those enterprises created are low tech micro enterprises which often employ only the entrepreneur themselves. This it has been suggested is due to a variety of factors, such as male prejudice which makes it hard to be taken seriously by funders, a lack of confidence in themselves, lack of access to support and cultural issues in general, for example where women are expected to look after the children. Using both quantitative and qualitative data from a questionnaire and interviews with three diverse female entrepreneurs, it was found that men still had a negative view of female entrepreneurship in India, a view shared by some women also. More specific problems included awareness of help and support and some not wanting to accept help as a sign of weakness. Support from friends and family was mixed, but was useful when offered. Women were broadly positive and confident about their skills and abilities whereas men’s views were more polarised toward female entrepreneurs. Suggestions for improving the situation included more support programs nationally and locally as has been successful elsewhere, but crucially making people more aware of the programmes. Networking, availability of mentors and awareness raising using positive case studies could be used effectively. Reducing male bias it was suggested could begin in university education or even before where entrepreneurship programmes could also be made available to increase the number of those who might start high growth technology businesses rather than micro enterprises.

description: We present a newly developed facility, comprised of a combinatorial laser molecular beam epitaxy system and an in-situ scanning tunneling microscopy (STM). This facility aims at accelerating the materials research in a highly efficient way, by advanced high-throughput film synthesis techniques and subsequent fast characterization of surface morphology and electronic states. Compared with uniform films deposited by conventional methods, the so-called combinatorial thin films will be beneficial to determining the accurate phase diagrams of different materials due to the improved control of parameters such as chemical substitution and sample thickness resulting from a rotarymask method. A specially designed STM working under low-temperature and ultra-high vacuum conditions is optimized for the characterization of combinatorial thin films, in an XY coarse motion range of 15 mm $\times$ 15 mm and with sub-micrometer location precision. The overall configuration as well as some key aspects like sample holder design, scanner head, and sample/tip/target transfer mechanism are described in detail. The performance of the device is demonstrated by synthesizing high-quality superconducting FeSe thin films with gradient thickness, imaging surfaces of highly oriented pyrolytic graphite, Au (111), Bi2Sr2CaCu2O8+δ (BSCCO) and FeSe. In addition, we have also obtained clean noise spectra of tunneling junctions and the superconducting energy gap of BSCCO. The successful manufacturing of such a facility opens a new window for the next generation of equipment designed for experimental materials research.

Black Hole Excision with Multiple Grid Patches

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

description: When using black hole excision to numerically evolve a black hole spacetime with no continuous symmetries, most 3+1 finite differencing codes use a Cartesian grid. It's difficult to do excision on such a grid, because the natural $r = \text{constant}$ excision surface must be approximated either by a very different shape such as a contained cube, or by an irregular and non-smooth "LEGO(tm) sphere" which may introduce numerical instabilities into the evolution. In this paper I describe an alternate scheme, which uses multiple $\{r \times (\text{angular coordinates}) \}$ grid patches, each patch using a different (nonsingular) choice of angular coordinates. This allows excision on a smooth $r = \text{constant}$ 2-sphere. I discuss the key design choices in such a multiple-patch scheme, including the choice of ghost-zone versus internal-boundary treatment of the interpatch boundaries, the number and shape of the patches, the details of how the ghost zones are "synchronized" by interpolation from neighboring patches, the tensor basis for the Einstein equations in each patch, and the handling of non-tensor field variables such as the BSSN $\tildeΓ^i$. I present sample numerical results from a prototype implementation of this scheme. This code simulates the time evolution of the (asymptotically flat) spacetime around a single (excised) black hole, using 4th-order finite differencing in space and time. Using Kerr initial data with $J/m^2 = 0.6$, I present evolutions to $t \gtsim 1500m$. The lifetime of these evolutions appears to be limited only by outer boundary instabilities, not by any excision instabilities or by any problems inherent to the multiple-patch scheme.

description: Urban water management (UWM) strategies are difficult to implement in the urban space due to conflicting professional objectives and lack of communication tools. We explore stakeholders, objectives and indicators for urban water management and urban planning to make UWM relevant for other urban disciplines. Stakeholder analysis was applied to systematically identify stakeholders and their objectives by screening literature published in professional journals and conference proceedings. The literature study was supplemented with three workshops. Similar sets of planning objectives and stakeholders were identified in the two analyses. Fourteen stakeholders were identified, from the utility to legal stakeholders. We identified 17 objectives and nine sub-objectives, that can be divided into four overall groups; welfare for citizens, environmental protection, economic growth and technical objectives. Our results are relevant for a variety of UWM projects, providing a common terminology when discussing objectives between stakeholders and enabling an exploration of multifunctional UWM strategies.

The local universality of Muttalib-Borodin ensembles when the parameter $θ$ is the reciprocal of an integer

description: The Muttalib-Borodin ensemble is a probability density function for $n$ particles on the positive real axis that depends on a parameter $θ$ and a weight $w$. We consider a varying exponential weight that depends on an external field $V$. In a recent article, the large $n$ behavior of the associated correlation kernel at the hard edge was found for $θ=\frac{1}{2}$, where only few restrictions are imposed on $V$. In the current article we generalize the techniques and results of this article to obtain analogous results for $θ=\frac{1}{r}$, where $r$ is a positive integer. The approach is to relate the ensemble to a type II multiple orthogonal polynomial ensemble with $r$ weights, which can then be related to an $(r+1)\times (r+1)$ Riemann-Hilbert problem. The local parametrix around the origin is constructed using Meijer G-functions. We match the local parametrix around the origin with the global parametrix with a double matching, a technique that was recently introduced.

description: Robert Mackintosh Duncan was my great uncle. He was the son of Alexander and Mary Duncan, of Whitehillock, Cabrach, Banffshire. He was born on 25th March 1891. He was serving in battle in Northern France but went missing during the battle on 21st March 1918. He was later found dead by German soldiers and buried by the Germans on 10th April 1918 at Foisney-le-Petit. It is unknown how he died or where he is buried. He is commemorated at the Pozieres Memorial. His service number is 202866.

Robert Mackintosh Duncan was one of 17 men from the Cabrach who lost their lives in battle during the First World War. They and others who died in subsequent conflicts are commemorated at the Cabrach Memorial Cairn situated at Inverharroch in the Lower Cabrach and the war memorial at Cabrach Church.
Antidumping and the global financial crisis : The impact on Latin America and the Caribbean

description: Global antidumping activity peaked in 2001, with 366 petitions initiated world-wide, and rapidly diminished to just 163 cases in 2007. With the onset of the current major world-wide recession some observers feared that antidumping usage would climb dramatically; however while antidumping activity was up by 28% in 2008 (to 208 cases initiated, according to WTO statistics), the rise was not nearly commensurate with the financial distress, and new antidumping initiations for the first three quarters of 2009 –at 154 cases– are on pace to show little change for the full year compared to the previous one (based on data from Bown’s Global Antidumping Database). However, antidumping has largely become a problem of the developing world, both in terms of major importing country users (e.g., the three largest users in 2008 were India, Brazil, and Turkey, the three largest users in 2009 so far have been Pakistan, India, and Argentina), and of targets (with China by far the largest exporting country hit by antidumping petitions, but Thailand, Taiwan and Indonesia the next largest targets of cases filed in 2008).

description: The subjective quality of transmitted speech is traditionally assessed in a controlled laboratory environment according to ITU-T Rec. P.800. In turn, with crowdsourcing, crowdworkers participate in a subjective online experiment using their own listening device, and in their own working environment. Despite such less controllable conditions, the increased use of crowdsourcing micro-task platforms for quality assessment tasks has pushed a high demand for standardized methods, resulting in ITU-T Rec. P.808. This work investigates the impact of the number of judgments on the reliability and the validity of quality ratings collected through crowdsourcing-based speech quality assessments, as an input to ITU-T Rec. P.808 . Three crowdsourcing experiments on different platforms were conducted to evaluate the overall quality of three different speech datasets, using the Absolute Category Rating procedure. For each dataset, the Mean Opinion Scores (MOS) are calculated using differing numbers of crowdsourcing judgements. Then the results are compared to MOS values collected in a standard laboratory experiment, to assess the validity of crowdsourcing approach as a function of number of votes. In addition, the reliability of the average scores is analyzed by checking inter-rater reliability, gain in certainty, and the confidence of the MOS. The results provide a suggestion on the required number of votes per condition, and allow to model its impact on validity and reliability.

description: In this research work, the Air pollution Tolerance Index of fifteen species collected from three different locations like Residential area, Industrial area and Heavy traffic area in Virudhunagar has been evaluated by analyzing biochemical parameters like Ascorbic acid, Chlorophyll, pH and Relative water content. The high values of Air pollution Tolerance Index were recorded in Moringa olifera, Azardiracta indica, Delonix regia, Mangifera indica, Eugenia jambolana and Fiscus religiosa for winter and summer season. The Air pollution Tolerance Index of plant species was also calculated by their Anticipated Performance Index together with other socio-economic and biochemical parameters. According to Anticipated performance index of most tolerant plant species for green belt development were Mangifera indica & Fiscus religiosa for road side and Azardiracta indica & Eugenia jambolona for industrial area.
On the detectability of lightcurves of Kuiper Belt objects

description: We present a statistical study of the detectability of lightcurves of Kuiper Belt objects (KBOs). Some Kuiper Belt objects display lightcurves that appear "flat", i.e., there are no significant brightness variations within the photometric uncertainties. Under the assumption that KBO lightcurves are mainly due to shape, the lack of brightness variations may be due to (1) the objects have very nearly spherical shapes, or (2) their rotation axes coincide with the line of sight. We investigate the relative importance of these two effects and relate it to the observed fraction of "flat" lightcurves. This study suggests that the fraction of KBOs with detectable brightness variations may provide clues about the shape distribution of these objects. Although the current database of rotational properties of KBOs is still insufficient to draw any statistically meaningful conclusions, we expect that, with a larger dataset, this method will provide a useful test for candidate KBO shape distributions.
