Abstract:

According to a beloved and now generally disbelieved story, the Cross upon which Jesus suffered was discovered some three hundred years after the event by the saintly Helena, mother of Constantine the Great, Rome's first Christian emperor. For centuries, this story enjoyed the greatest vogue, blossoming into a full-blown Legend of the Cross which traced its genealogy all the way back to the Garden of Eden. With the waning of the Middle Ages, however, came new criteria for evidence, and with them a scholarly predisposition to dismiss the discovery, as well as the legend, as pure bunkum. Put together all the pieces of the True Cross, it became common to say, and one could float a fine freighter.

Abstract:

True cross-rolling and pseudo cross-rolling (with only one change of the rolling direction after half of the total deformation degree) was investigated in an alloy AlMn1 up to 93% deformation. The texture formation was studied in terms of ODF. After true cross-rolling (multi-stage rolling) a strong two-component ideal orientation near (011)[322] was found with maximum densities up to 60 times random. Pseudo cross-rolling (two-stage rolling) resulted in weaker, but still strong deformation textures with maximum densities up to twenty times random which were intermediate between unidirectional and true cross-rolling textures. In both cases, the originally present cube texture decreased continuously with increasing deformation degree.

Abstract:

The classical calibration problem is primarily concerned with comparing an approximate measurement method with a very precise one. Frequently, both measurement methods are very noisy, so we cannot regard either method as giving the true value of the quantity being measured. Sometimes, it is desired to replace a destructive or slow measurement method, by a noninvasive, faster or less expensive one. The simplest solution is to cross calibrate one measurement method in terms of the other. The common practice is to use regression models, as cross calibration formulas. However, such models do not attempt to discriminate between the clutter and the true functional relationship between the cross calibrated measurement methods. A new approach is proposed, based on minimizing the sum of squares of the differences between the absolute values of the Fast Fourier Transform (FFT) series, derived from the readings of the cross calibrated measurement methods. The line taken is illustrated by cross calibration examples of simulated linear and nonlinear measurement systems, with various levels of additive noise, wherein the new method is compared to the classical regression techniques. It is shown, that the new method can discover better the true functional relationship between two measurement systems, which is occluded by the noise.

Abstract:

Whole-genome sequencing (WGS) is promising for the quality control of laboratory facilities for Mycobacterium tuberculosis (MTB) strains. We describe the clinical and laboratory characteristics of false positive versus true positive MTB cultures based on WGS, which were experienced in a real clinical setting. Strain harvest and DNA extraction from seven isolates from pre-extensive drug-resistant (pre-XDR) TB patients transferred to the Korea University Ansan Hospital were performed, and epidemiologic links and clinical information, including the phenotypic drug susceptibility test (pDST), were investigated. WGS was performed using Ion GeneStudio with an ION530tm chip (average sequencing depth, ~100-fold). In the phylogenetic tree, identical and different strains were distributed separately. Five of the seven isolates were identical; the remaining two isolates differed from the others. The images of the referred pre-XDR-TB patients with false positive MTB that were analyzed were of regions close to old TB scars. Further, the results of WGS gene mutation analysis for ethambutol, streptomycin, and fluoroquinolone resistance in all six patients were not concordant with the pDST results. WGS and clinical information were useful in differentiating laboratory cross-contamination from true positive TB, thereby avoiding the unnecessary treatment of false positive patients and delay in treating true positive TB patients, with reliable genotypic drug resistance results.

Abstract:

Likelihood-based cross-validation is a statistical tool for selecting a density estimate based on n i.i.d. observations from the true density among a collection of candidate density estimators. General examples are the selection of a model indexing a maximum likelihood estimator, and the selection of a bandwidth indexing a nonparametric (e.g. kernel) density estimator. In this article, we establish a finite sample result for a general class of likelihood-based cross-validation procedures (as indexed by the type of sample splitting used, e.g. V-fold cross-validation). This result implies that the cross-validation selector performs asymptotically as well (w.r.t. to the Kullback-Leibler distance to the true density) as a benchmark model selector which is optimal for each given dataset and depends on the true density. Crucial conditions of our theorem are that the size of the validation sample converges to infinity, which excludes leave-one-out cross-validation, and that the candidate density estimates are bounded away from zero and infinity. We illustrate these asymptotic results and the practical performance of likelihood-based cross-validation for the purpose of bandwidth selection with a simulation study. Moreover, we use likelihood-based cross-validation in the context of regulatory motif detection in DNA sequences.

Abstract:

Tom Ruys’s article in the latest issue of the American Journal of International Law is an erudite study of the prohibition on the use of force in UN Charter Article 2(4). Ruys makes many points with which I wholeheartedly agree. In note 241, he says that the case for cross-border drone attacks by the United States “verges on stretching criteria for necessity, proportionality, and armed attack to the point of absurdity . . . .” He is also right to reject emerging claims that the defense of necessity provides a basis for the lawful resort to force. Indeed, there is much that is truly excellent about the article—just not, unfortunately, its central thesis.

Abstract:

Abstract Recent analyses of genomic sequence data suggest cross-species gene flow is common in both plants and animals, posing challenges to species tree estimation. We examine the levels of gene flow needed to mislead species tree estimation with three species and either episodic introgressive hybridization or continuous migration between an outgroup and one ingroup species. Several species tree estimation methods are examined, including the majority-vote method based on the most common gene tree topology (with either the true or reconstructed gene trees used), the UPGMA method based on the average sequence distances (or average coalescent times) between species, and the full-likelihood method based on multilocus sequence data. Our results suggest that the majority-vote method based on gene tree topologies is more robust to gene flow than the UPGMA method based on coalescent times and both are more robust than likelihood assuming a multispecies coalescent (MSC) model with no cross-species gene flow. Comparison of the continuous migration model with the episodic introgression model suggests that a small amount of gene flow per generation can cause drastic changes to the genetic history of the species and mislead species tree methods, especially if the species diverged through radiative speciation events. Estimates of parameters under the MSC with gene flow suggest that African mosquito species in the Anopheles gambiae species complex constitute such an example of extreme impact of gene flow on species phylogeny.

Abstract:

The True Cross, understood by the Christian faithful as the wood on which Christ was crucified, was legendarily discovered by Helena, the mother of Byzantine Emperor Constantine I, in 362 CE in Jerusalem. This discovery established imperial Byzantine control of the Cross and its relics, limiting their movement out of Byzantium. With the Crusader sack of Constantinople in 1204, reliquaries of the True Cross became more accessible. Many were taken west into the treasuries of Western European churches, where they can still be found today. The reception of these objects varied, but often, western viewers imposed new identities on these reliquaries by refashioning them or assigning them new narratives. One such reliquary of the True Cross that traveled from Byzantium to the west is now known as the Croce degli Zaccaria. In the pages that follow I will examine how the Byzantine identity of this reliquary was perceived as it moved through the medieval world.

Abstract:

AbstractWe demonstrate analytically that cross-sectional variation in the effects of events, i.e., in true abnormal returns, necessarily produces event-induced variance increases, biasing popular tests for mean abnormal returns in short-horizon event studies. We show that unexplained cross-sectional variation in true abnormal returns plausibly produces nonproportional heteroskedasticity in cross-sectional regressions, biasing coefficient standard errors for both ordinary and weighted least squares. Simulations highlight the resulting biases, the necessity of using tests robust to cross-sectional variation, and the power of robust tests, including regression-based tests for nonzero mean abnormal returns, which may increase power by conditioning on relevant explanatory variables.

Abstract:

Abstract We present a method for 3D measurement of fiber cross sectional morphology from handsheets. An automated procedure is used to acquire 3D datasets of fiber cross sectional images using an automated microtome and light microscopy. The fiber cross section geometry is extracted using digital image analysis. Simple sample preparation and highly automated image acquisition and image analysis are providing an efficient tool to analyze large samples. It is demonstrated that if fibers are tilted towards the image plane the images of fiber cross sections are always larger than the true fiber cross section geometry. In our analysis the tilting angles of the fibers to the image plane are measured. The resulting fiber cross sectional images are distorted to compensate the error due to fiber tilt, restoring the true fiber cross sectional shape. We use an approximated correction, the paper provides error estimates of the approximation. Measurement results for fiber wall thickness, fiber coarseness and fiber collapse are presented for one hardwood and one softwood pulp.

Full text

Abstract:

This paper addresses the issue of the sensitivity of 3‐D prestack depth migration (PSDM) with respect to the acquisition geometry of 3‐D seismic surveys. Using the theoretical framework of PSDM, I show how acquisition‐related imaging artifacts—the acquisition footprints—can arise. I then show how the acquisition footprint can be suppressed in two steps by (1) partitioning the 3‐D survey into minimal data sets, each to be migrated separately, and (2) applying a robust variable‐geometry PSDM quadrature. The validity of the method is demonstrated on synthetic parallel and antiparallel multistreamer data and cross‐spread data. The proposed two‐step solution can play an important role in projects where amplitude integrity and fidelity are paramount, e.g., quantitative interpretation and time‐lapse surveying. The concept of minimal data also fills a gap in understanding the relation between acquisition and imaging.

Abstract:

The problem of determining true stress-strain curves from flat tensile specimens beyond the onset of necking has been investigated based on finite element analyses under consideration of experimental accessible data using digital image correlation (DIC). The displacement field on the specimen surface is determined by in-situ deformation field measurement. A three-dimensional finite element study with different stress-strain-curves has been carried out to develop a formula, with which it is possible to calculate the true stress subject to the strain in the necking region. The method has been used to evaluate the true stress-strain curve with a so-called micro flat tensile specimen, which is normally used to determine the material properties in the material gradient around thin weldments.

Abstract:

Bending performances of aluminum square tube beams reinforced by aluminum plates under three point bending loads have been evaluated using experimental tests combined with theoretical and finite element analyses. Basic properties of aluminum materials used for initial input data of the finite element simulation were obtained from the true stress-true strain curves of specimens which had bean extracted from the Al tube beams. True stresses were determined from applied loads and cross-sectional area records of a tensile specimen with a rectangular cross-section by real-time photographing. True strains were obtained from in-situ local elongation measurements of the specimen gage portion by the multi-point scanning laser extensometer. Four kinds of aluminum tube beam specimens adhered by aluminum plates were employed. The bending deformation behaviors up to the maximum load described by the numerical simulation were in good agreement with experimental ones. An aluminum tube beam strengthened by aluminum plate on the upper web showed an excellent bending capability.

Abstract:

Although sexual orientation (SO) is perceptually ambiguous, people are able to detect it with above-chance accuracy from faces and, sometimes, from voices. Despite a multitude of “gaydar” studies, it is unclear (1) whether vocal or facial signals carry more SO information, (2) whether raters refer to target’s SO instead of gender-role conformity when forming SO impressions, and (3) whether there are any differences for female and male targets. We collected face photographs, voice recordings, and self-reported gender-role conformity of 18 lesbian/gay and straight female and male target persons each. Study 1 (rating of SO) showed that faces led to higher accuracies than voices, which was especially true for female targets. Study 2 (rating of gender-role conformity) showed that the link between self-reported and attributed SO was mediated by self-reported and attributed gender-role conformity. Results support the centrality of gender-role conformity, more than that of SO, in impression formation.

Abstract:

There is something extremely paradoxical about the modern world. Different societies have become increasingly interdependent, the solutions to the problems facing them impossible to separate, yet at the same time the diversity of those societies is very marked, whether it stems from their growing disparity in terms of development or from the desire of individuals and communities to affirm their identity. As the twentieth century draws to a close, the challenge is to lay the foundations of the true spirit of human fellowship required to reduce disparities and inequality while respecting differences and identities.

Abstract:

Probabilities of discrepancy between minima of cross-validation, Vapnik bounds and true risksTwo known approaches to complexity selection are taken under consideration:n-fold cross-validation and structural risk minimization. Obviously, in either approach, a discrepancy between the indicated optimal complexity (indicated as the minimum of a generalization error estimate or a bound) and the genuine minimum ofunknown true risksis possible. In the paper, this problem is posed in a novel quantitative way. We state and prove theorems demonstrating how one can calculate pessimistic probabilities of discrepancy between these minima for given for given conditions of an experiment. The probabilities are calculated in terms of all relevant constants: the sample size, the number of cross-validation folds, the capacity of the set of approximating functions and bounds on this set. We report experiments carried out to validate the results.

Abstract:

AbstractIn this study of the Ethiopian Orthodox Mäsqäl festival, we have chosen to focus upon the multiple ways in which diverse and even contradictory social messages have been dramatized through this celebration throughout its more than five hundred years of recorded history. While portrayals of imperial power are perhaps the most obvious features of the festival, they were only one aspect of Mäsqäl celebrations. Other issues of rank and hierarchy were portrayed in various means including the construction, lighting and circling of the bonfire and the distribution and division of food. However, these images of a clearly organized and broadly acknowledged social and political order were challenged, not only by 'crises' which came to the surface at the time of the ritual, but also in clearly ritualized games and battles, which dramatized and expressed the tensions that were a constant feature of any social-political system.

Abstract:

True allergic reactions are IgE-mediated immune reactions and are also termed type I reactions, where the spectrum of presentation may range from urticaria to severe anaphylactic shock. Currently, 3% of the patients who use sulfonamide antibiotics develop an allergic reaction, with the most common being the development of a maculopapular rash. Sulfonamides are chemical compounds that can be further divided into 3 groups based on differences in their structural makeup. Several cases reviewing the cross-reactivity between sulfonamide antibiotics and nonantibiotics have suggested an increased risk of cross-reactivity and therefore recommend other treatment strategies to avoid a possible anaphylactic reaction; however, other reports argue that patients with a history of sulfonamide allergy who received sulfonamide nonantibiotics did not experience any adverse reactions. Pertinent data extracted from these studies are reviewed and evaluated.

Abstract:

Measuring cosmic shear in wide-field imaging surveys requires accurate knowledge of the redshift distribution of all sources. The clustering-redshift technique exploits the angular cross-correlation of a target galaxy sample with unknown redshifts and a reference sample with known redshifts. It represents an attractive alternative to colour-based methods of redshift calibration. Here we test the performance of such clustering redshift measurements using mock catalogues that resemble the Kilo-Degree Survey (KiDS). These mocks are created from the MICE simulation and closely mimic the properties of the KiDS source sample and the overlapping spectroscopic reference samples. We quantify the performance of the clustering redshifts by comparing the cross-correlation results with the true redshift distributions in each of the five KiDS photometric redshift bins. Such a comparison to an informative model is necessary due to the incompleteness of the reference samples at high redshifts. Clustering mean redshifts are unbiased at |Δz|< 0.006 under these conditions. The redshift evolution of the galaxy bias of the reference and target samples represents one of the most important systematic errors when estimating clustering redshifts. It can be reliably mitigated at this level of precision using auto-correlation measurements and self-consistency relations, and will not become a dominant source of systematic error until the arrival of Stage-IV cosmic shear surveys. Using redshift distributions from a direct colour-based estimate instead of the true redshift distributions as a model for comparison with the clustering redshifts increases the biases in the mean to up to |Δz|∼0.04. This indicates that the interpretation of clustering redshifts in real-world applications will require more sophisticated (parameterised) models of the redshift distribution in the future. If such better models are available, the clustering-redshift technique promises to be a highly complementary alternative to other methods of redshift calibration.

Abstract:

AbstractExperimentation is an increasingly popular method among political scientists. While experiments are highly advantageous for creating internally valid conclusions, they are often criticized for being low on external validity. Critical to questions of external validity are the types of subjects who participate in a given experiment, with scholars typically arguing that samples of adults are more externally valid then student samples. Despite the vociferousness of such arguments, these claims have received little empirical treatment. In this paper we empirically test for key differences between student and adult samples by conducting four parallel experiments on each of the three samples commonly used by political scientists. We find that our student and diverse, national adult sample behave consistently and in line with theoretical predictions once relevant moderators are taken into account. The same is not true for our adult convenience sample.

Abstract:

This study used elemental and stable isotope composition to characterize Slovenian truffles and used multi-variate statistical analysis to classify truffles according to species and geographical origin. Despite the fact that the Slovenian truffles shared some similar characteristics with the samples originating from other countries, differences in the element concentrations suggest that respective truffle species may respond selectively to nutrients from a certain soil type under environmental and soil conditions. Cross-validation resulted in a 77% correct classification rate for determining the geographical origin and a 74% correct classification rate to discriminate between species. The critical parameters for geographical origin discriminations were Sr, Ba, V, Pb, Ni, Cr, Ba/Ca and Sr/Ca ratios, while from stable isotopes δ18O and δ13C values are the most important. The key variables that distinguish T. magnatum from other species are the levels of V and Zn and δ15N values. Tuber aestivum can be separated based on the levels of Ni, Cr, Mn, Mg, As, and Cu. This preliminary study indicates the possibility to differentiate truffles according to their variety and geographical origin and suggests widening the scope to include stable strontium isotopes.

Abstract:

The article deals with the problem of determining the ultimate load for the eccentrically loaded steel columns with variable-cross section.The purpose of the research work is to offer an evaluation technique and practical calculation of load-bearing ability of the beam-columns with variable cross-section on the basis of numerical research, which will allow to consider the true form of element deflection curve, the effect of cross-section form, physical nonlinearity of the material, and variety of element boundary conditions. The distinctive characteristic of the suggested method is usage of the discrete models for cross-sectional parts, for the true stress-strain curves of the materials, and for the other input data. The method was tested and the results were compared to known theoretical solutions and national standards. To establish the reliability of the developed method, the experimental study of steel columns with variable cross-section was conducted. The suggested method allows to obtain column curves tables of lowering coefficients for these elements, that can be used in practice of civil engineering, and are convenient with national standards and Eurocode.

Abstract:

The directors of the Dutch West India Company gambled their reputations and capital in a decades-long scheme to conquer and pacify Brazil, and in the end, they lost. This essay explores the various religious elements of that scheme or “mission,” as it was also called: establishing the Dutch Reformed Church as the colony’s public church, spreading the message of the “true religion,” attacking sin and reforming sinners. Coupled with a general, widespread sense of anti-Catholicism and anti-clericalism among the Dutch in Europe and America, these reform efforts exacerbated differences between the conquerors and conquered and contributed to Portuguese discontent in the years before the 1645 revolt.
