description: Rendering large point clouds ordinarily requires building a hierarchical data structure for accessing the points that best represent the object for a given viewing frustum and level-of-detail. The building of such data structures frequently represents a large portion of the cost of the rendering pipeline both in terms of time and space complexity, especially when rendering is done for inspection purposes only. This problem has been addressed in the past by incremental construction approaches, but these either result in low quality hierarchies or in longer construction times. In this work we present OMiCroN -- Oblique Multipass Hierarchy Creation while Navigating -- which is the first algorithm capable of immediately displaying partial renders of the geometry, provided the cloud is made available sorted in Morton order. OMiCroN is fast, being capable of building the entire data structure in memory spending an amount of time that is comparable to that of just reading the cloud from disk. Thus, there is no need for storing an expensive hierarchy, nor for delaying the rendering until the whole hierarchy is read from disk. In fact, a pipeline coupling OMiCroN with an incremental sorting algorithm running in parallel can start rendering as soon as the first sorted prefix is produced, making this setup very convenient for streamed viewing.

description: We have reconsidered theoretical upper bounds on the scalar boson masses within the two-Higgs-doublet model (THDM), employing the well-known technical condition of tree-level unitarity. Our treatment provides a modest extension and generalization of some previous results of other authors. We present a rather detailed discussion of the solution of the relevant inequalities and offer some new analytic formulae as well as numerical values for the Higgs mass bounds in question. A comparison is made with the earlier results on the subject that can be found in the literature.

Accounting for periods of temporary disequilibrium leads to notably more stable risk measurement estimates.
Applying Messick’s framework to the evaluation data of distance/distributed intructional programs
Creators: name: Ruhe, Valeria
Publisher: name: University of British Columbia
Year: 2009

description: In the past twenty years, the literature of evaluation in distance education has evolved largely independently of the literature of program evaluation. A survey of evaluation models for distance instructional programs shows that these models have not included unintended consequences or value implications as explicit evaluation criteria. Consequently, using these models in program evaluation studies may tend to produce findings which are incomplete. Because it does include unintended consequences and value implications, Messick's (1989) framework on validity can be used to guide evaluation studies of distance instructional programs. In this mixed methods study, I will take an adapted version of Messick's (1989) framework for a "test-drive" by applying it to authentic evaluation data from three BC postsecondary courses--Modern Languages 400, Psychology 101 and MCSE (Microsoft Certified Systems Engineer). Qualitative findings will then be compared with survey findings to obtain an in-depth understanding of the workings of the three implementation systems. My findings demonstrate that the adapted Messick's (1989) framework can be very useful in guiding the evaluation of distance programs because it provides a comprehensive assessment of merit and worth. Moreover, the application of this framework resonates with Stake's (1995) responsive approach to evaluation, so that applying the framework brings an easy-to-use and reputable approach to program evaluation into the field of evaluation of distance education.
Are direct search experiments sensitive to all spin-independent WIMP candidates?

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

description: The common analysis of direct searches for spin-independent Weakly Interacting Massive Particles (WIMPs) assumes that a spin-independent WIMP couples with the same strength with both nucleons, \textit{i.e.} that the spin-independent interaction is also fully isospin-independent. Though in a fully isospin-dependent interaction scenario the spin-independent WIMP-nucleus cross section is strongly quenched, the leading experiments are still sensitive enough to set limits 1-2 orders of magnitude less stringent than those traditionally presented. In the isospin-dependent scenario the difference between the limits of CDMS-II and ZEPLIN-I is significantly reduced. Here, a model-independent framework is discussed and applied to obtain the current general model-independent limits.

description: The Two Higgs Doublet Model predicts the emergence of 3 distinct domain wall solutions arising from the breaking of 3 accidental global symmetries, $Z_2$, CP1 and CP2, at the electroweak scale for specific choices of the model parameters. We present numerical kink solutions to the field equations in all three cases along with dynamical simulations of the models in (2+1) and (3+1) dimensions. For each kink solution we define an associated topological current. In all three cases simulations produce a network of domain walls which deviates from power law scaling in Minkowski and FRW simulations. This deviation is attributed to a winding of the electroweak group parameters around the domain walls in our simulations. We observe a local violation of the neutral vacuum condition on the domain walls in our simulations. This violation is attributed to relative electroweak transformations across the domain walls which is a general feature emerging from random initial conditions.

Suppression of pions and kaons and enhancement for protons in central Au+Au collisions is observed. These results are found to be very similar in strength to that observed at mid-rapidity. Furthermore, we see a gradual decrease of the observed suppression towards more peripheral collisions.

description: Over 90 percent of interstate produce movements are by truck. In recent years, concerns have been raised regarding the adequacy of motor carrier services. Reasons for these concerns include the possibility of increased costs or service erosions resulting from relaxed economic regulations, an eroding road infrastructure, increasing congestion, more stringent safety regulations, demographic trends suggesting the onset of an increasingly severe driver shortage, and declines in rail capacity devoted to produce haulage. In this study, trends in the adequacy of trucking services for trucking during the 1980s was examined employing data sets developed by the USDA regarding haulage from five growing areas to six metropolitan areas across the United States, and a case study based on over 9,000 interviews with drivers hauling Florida produce, conducted between 1982 and 1989. The results of the study suggest that ther have been no erosions in service adquacies.

description: When a fs duration and hundreds of kA peak current electron beam traverses the vacuum and high-density plasma interface a new process, that we call relativistic transition radiation (R-TR) generates an intense $\sim100$ as pulse containing $\sim$ TW power of coherent VUV radiation accompanied by several smaller fs duration satellite pulses. This pulse inherits the radial polarization of the incident beam field and has a ring intensity distribution. This R-TR is emitted when the beam density is comparable to the plasma density and the spot size much larger than the plasma skin depth. Physically, it arises from the return current or backward relativistic motion of electrons starting just inside the plasma that Doppler up-shifts the emitted photons. The number of R-TR pulses is determined by the number of groups of plasma electrons that originate at different depths within the first plasma wake period and emit coherently before phase mixing.

We used traditional survival analysis methods (Fine-Gray models) and a data-driven approach (random survival forests for competing risks) which allowed us to account for the competing risk of death with up to 14 years of follow-up. Overall, the top five predictors across all groups were lower education, loneliness, lower wealth and income, and lower self-reported health. However, we observed variation in the leading predictors of dementia across racial/ethnic and gender groups. Our ranked lists may be useful for guiding future observational and quasi-experimental research that investigates understudied domains of risk and emphasizes life course economic and health conditions as well as disparities therein.
Build Scripts with Perfect Dependencies

Year: 2020
Subjects: subject: Programming Languages (cs.PL)
subject: FOS: Computer and information sciences

description: Build scripts for most build systems describe the actions to run, and the dependencies between those actions---but often build scripts get those dependencies wrong. Most build scripts have both too few dependencies (leading to incorrect build outputs) and too many dependencies (leading to excessive rebuilds and reduced parallelism). Any programmer who has wondered why a small change led to excess compilation, or who resorted to a "clean" step, has suffered the ill effects of incorrect dependency specification. We outline a build system where dependencies are not specified, but instead captured by tracing execution. The consequence is that dependencies are always correct by construction and build scripts are easier to write. The simplest implementation of our approach would lose parallelism, but we are able to recover parallelism using speculation.

description: We describe a cooperad structure on the simplicial bar construction on a reduced operad of based spaces or spectra and, dually, an operad structure on the cobar construction on a cooperad. We also show that if the homology of the original operad (respectively, cooperad) is Koszul, then the homology of the bar (respectively, cobar) construction is the Koszul dual. We use our results to construct an operad structure on the partition poset models for the Goodwillie derivatives of the identity functor on based spaces and show that this induces the `Lie' operad structure on the homology groups of these derivatives. We also extend the bar construction to modules over operads (and, dually, to comodules over cooperads) and show that a based space naturally gives rise to a left module over the operad formed by the derivatives of the identity.

description: Double-cropping of soybeans and wheat is often promoted by extension personnel. This paper seeks to explain how the decision to adopt double-cropping is made, using a Tobit regression model. Tobit makes use of more of the information in the data set than do logit or probit and explains not only the decision to double-crop but also the rate of adoption. The paper considers factors such as profit and risk perceptions and risk which have not been included in the past models used to explain adoption of technology. The results show that risk perception is important. Contrary to the findings of some other adoption studies, this decision is not influenced by human capital factors. The farmers who double-crop are more highly leveraged and appear to do so both to achieve higher income and as part of a risk diversification strategy. This is consistent with the importance of the location factor, measured as the average number of growing degree days at the farm's location. Growing degree days is a proxy for the actual distribution of returns from double-cropping and is the main factor explaining this decision. Extensive adoption of double-cropping in cooler regions of the Midwest must await technological advances that can increase the profitability of double-cropping by reducing the growing season for wheat and/or beans.

description: The current pandemic, caused by the outbreak of a novel coronavirus (COVID-19) in December 2019, has led to a global emergency that has significantly impacted economies, healthcare systems and personal wellbeing all around the world. Controlling the rapidly evolving disease requires highly sensitive and specific diagnostics. While real-time RT-PCR is the most commonly used, these can take up to 8 hours, and require significant effort from healthcare professionals. As such, there is a critical need for a quick and automatic diagnostic system. Diagnosis from chest CT images is a promising direction. However, current studies are limited by the lack of sufficient training samples, as acquiring annotated CT images is time-consuming. To this end, we propose a new deep learning algorithm for the automated diagnosis of COVID-19, which only requires a few samples for training. Specifically, we use contrastive learning to train an encoder which can capture expressive feature representations on large and publicly available lung datasets and adopt the prototypical network for classification. We validate the efficacy of the proposed model in comparison with other competing methods on two publicly available and annotated COVID-19 CT datasets. Our results demonstrate the superior performance of our model for the accurate diagnosis of COVID-19 based on chest CT images.
Spatial structure of neutron Cooper pair in low density uniform matter

description: We analyze spatial structure of the neutron Cooper pair in superfluid low-density uniform matter by means of BCS calculations employing a bare force and the effective Gogny interaction. It is shown that the Cooper pair exhibits a strong spatial di-neutron correlation in a wide range of neutron density $ρ/ρ_0\approx 10^{-4}-0.5$. This feature is related to the crossover behavior between the pairing of the weak coupling BCS type and the Bose-Einstein condensation of bound neutron pairs. We also show that the zero-range delta interaction can describe the spatial structure of the neutron Cooper pair if the density dependent interaction strength and the cut-off energy are appropriately chosen. Parameterizations of the density-dependent delta interaction satisfying this condition are discussed.

description: wo-dimensional (2D) materials unique properties and their promising applications in post-silicon microelectronics have attracted significant attention in the past decade. Recently, ferromagnetic order with out-of-plane easy axis in a monolayer of CrI3 has been observed and reported, with a Curie temperature of 45 K. Here we study, using density functional theory (DFT) calculations, how hydrogen and oxygen adsorption affects the structural, electronic, and magnetic properties of a CrI3 monolayer. Our results show that while the structure remains almost unchanged by the adsorption of hydrogen, adsorption of oxygen completely distorts it. We have also found that both the adsorption of hydrogen and oxygen atoms significantly influences the electronic and magnetic properties of the monolayer. While hydrogen quenches the magnetic moments of Cr atoms, oxygen introduces an impurity band in the gap. Interestingly, we find a strong enhancement of the Curie temperature by full hydrogenation, while the results are not conclusive for O. This result suggests a simple and effective approach to manipulate the electronic and magnetic properties of 2D magnets for spintronics applications.

Subjects: Demand and Price Analysis

description: Recent empirical research and development in the cattle industry suggest several reasons to suspect structural change in economic relationships determining cattle prices. Standard forecasting models may ignore structural change and may produce biased and misleading forecasts. Vector autoregressive (VAR) models that allow parameters to vary with time are used to forecast quarterly cattle prices. The VAR procedures are flexible in that they allow the identification of structural change that begins at an a priori unknown point and occurs gradually. The results indicate that the lowest RMSE for out-of-sample forecasts of cattle prices is obtained using a gradually switching VAR model. However, differences between the gradually switching VAR model and a univeriate ARIMA model are not strongly significant. Impulse response functions indicate that adjustments of cattle prices to new information have become faster in recent years.

description: An econometric model of the dairy industry was used to estimate the effects on farmers, consumers, and taxpayers of nationwide adoption of the California nonfat solids standards for fluid milk. It was estimated that adoption of the California standards would raise farm-level milk prices by 1 to 5 percent in the short run and by 1 to 2 percent in the long run. The average retail price of fluid milk would rise by 9 to 13 cents per gallon. Dairy program costs fall under most scenarios, but could rise if surpluses fall to levels that would trigger increases in the support price.

Many wholesalers have established or are seriously considering the establishment of broad programs to assist retail grocers in becoming more efficient and effective operators. This is a summary of questionnaires returned by 1,695 independent grocers giving their views on wholesaler assistance programs. The retailers covered in the survey were customers of eight wholesalers selected to represent houses with different points of view on the extent to which retailer assistance should be offered. Completed returns were received from 1,439 grocers to whom questionnaires were sent and 256 interviews were made among grocers who did not respond by mail.

description: Most existing point-based colocation methods are global measures (e.g., join count statistic, cross K function, and global colocation quotient). Most recently, a local indicator such as the local colocation quotient is proposed to capture the variability of colocation across areas. Our research advances this line of work by developing a simulation-based statistic test for the local indicator of colocation quotient (LCLQ). The study applies the indicator to examine the association of land use facilities with crime patterns. Moreover, we use the street network distance in addition to the traditional Euclidean distance in defining neighbors since human activities (including facilities and crimes) usually occur along a street network. The method is applied to analyze the colocation of three types of crimes and three categories of facilities in a city in Jiangsu Province, China. The findings demonstrate the value of the proposed method in colocation analysis of crime and facilities, and in general colocation analysis of point data.

description: Recreation demand studies have traditionally utilized a two-step valuation method, estimating condtional recreation participation probabilities and then intensity of use decisions. These two steps of analysis are combined to estimate the use value of natural resource recreation sites. The purpose of this paper is to provide a method by which use value can be estimated solely from the participation decision. The one-step resource valuation method allows estimation of use values from coefficients of the logistic regression recreation participation equation. The benefits of the method are the reduced data and effort required to value natural resource areas.

description: This article examines the development of legal and penal systems in the Central Asian khanates from the 16th to the 19th centuries. Through a comprehensive literature review and analysis, it explores the foundations of law, the structure of punishment systems, and the methods of reward in the Bukhara, Khiva, and Kokand khanates. The study highlights the interplay between Sharia law, customary practices, and khan's decrees in shaping the legal landscape. It also investigates the gradual changes in these systems over time, influenced by internal dynamics and external pressures, particularly from the Russian Empire. The findings reveal a complex legal framework that reflected the social, cultural, and political realities of Central Asia during this period.

Transaction prices were significantly affected by the percentage of cattle expected to grade choice times the choice-to-select carcass price spread, finish uniformity, average weight, dressing percentage, breed, number of cattle purchased by a single packer on a given day, the packer, the feedyard, the day-of-the-week the cattle were sold, and the number of bids received. Asking prices were significantly affected by many of the same factors. Asking and transaction prices reflected approximately 25 percent of the packer value differentials for expected carcass quality grades.

description: For the first time we show that the quasiclassical limit of the symmetry constraint of the KP hierarchy leads to the generalized Zakharov reduction of the dispersionless KP (dKP) hierarchy which has been proved to be result of symmetry constraint of the dKP hierarchy recently. By either regarding the constrained dKP hierarchy as its stationary case or taking the dispersionless limit of the KP hierarchy with self-consistent sources directly, we construct a new integrable dispersionless hierarchy, i.e., the dKP hierarchy with self-consistent sources and find its associated conservation equations (or equations of Hamilton-Jacobi type). Some solutions of the dKP equation with self-consistent sources are also obtained by hodograph transformations.

description: We investigate the possiblity to detect Earth-like planets, in the visible and the near infrared domains, with ground based Extremely Large Telescopes equipped with adaptive systems capable of providing high Strehl ratios. From a detailed analysis of the speckle noise, we derive analytical expressions of the signal to noise ratio on the planet flux, for direct and differential imaging, in the presence of the speckle noise and the photon noise of the residual stellar halo. We find that a 100m telescope would detect an Earth at a distance of 10pc, with a signal to noise ratio of 5, in an integration time of 12 hours. This requires to control the instrumental aberrations with a precision better than 1 nanometer rms, and to reach an image dynamics of $1.2{\rm x}10^{6}$ at $0\farcs 1$ radius. Under the same conditions, a telescope of 30m would require a dynamics of $1.3{\rm x}10^{7}$ for a positive detection

description: Data from a western Kansas feedlot were analyzed to estimate the quantitative impacts of price and performance variables on profits per head from finishing cattle. Sale prices, feeder prices, and corn prices had the most impact on profit variability over time. Differences in sale prices, feeder prices, and feed conversions were important in explaining the difference in steer and heifer profits over time. Results suggest that breakeven prices should be calculated for a range of fed cattle, feeder, and corn prices, and that these three variables need to be stochastic in representative farm modeling efforts.

description: Three variational approaches, the hyperspherical-harmonics, Gaussian-basis and Lagrange-mesh methods involving different coordinate systems, are compared in studies of $0^+$ bound-state energies in 3$α$ models. Calculations are performed with different versions of the shallow Ali-Bodmer potential (with and without Coulomb) and with the deep Buck-Friedrich-Wheatley potential. All three methods yield very accurate energies. Their advantages and drawbacks are evaluated. The implications of the disagreement between the obtained results and the experimental $^{12}$C energies in $3α$ models with Coulomb interaction are discussed.

description: Local conformal symmetry introduces the conformal curvature (Weyl tensor) that gets split into its (gravito-) electric and magnetic (tensor) parts. Newtonian tidal forces are expected from the gravitoelectric field, whereas general-relativistic frame-dragging effects emerge from the gravitomagnetic field. The symmetric, traceless gravitoelectric and gravitomagnetic tensor fields can be visualized by their eigenvectors and eigenvalues. In this essay, we depict the gravitoelectric and gravitomagnetic fields around a slowly rotating black hole. This suggests that the phenomenon of ultra-fast outflows observed at the centers of active galaxies may give evidence for the gravitomagnetic fields of spinning supermassive black holes. We also question whether the current issues in our contemporary observations might be resolved by the inclusion of gravitomagnetism on large scales in a perturbed FLRW model.

description: Ανέκαθεν, οι παράκτιες ζώνες αποτελούσαν και αποτελούν νευραλγικές περιοχές για τα αστικά περιβάλλοντα. Το Ηράκλειο ως μία από τις σημαντικότερες ελληνικές πόλεις δεν αποτελεί εξαίρεση, καθώς η παράκτια ζώνη και ιδίως το λιμάνι του διαθέτει πλούσιο ιστορικό υπόβαθρο. Ωστόσο, η τωρινή κατάσταση της περιοχής μεταξύ του παλαιού και του σύγχρονου λιμένα επιδεικνύει αρκετές παθογένειες: η παραλιακή λεωφόρος αποκόπτει την πόλη από τη θάλασσα, τα ιστορικά στοιχεία και τα μνημεία της περιοχής παραμένουν αναξιοποίητα και αποκρυμμένα και η περιοχή δεν είναι κατάλληλα εξοπλισμένη ώστε να εκπληρώσει τις δυνατότητες της. Για αυτό τον λόγο προτείνουμε την αναδιαμόρφωση της περιοχής, τη συνομιλία με την ιστορία του τόπου και την ανάδειξη της καθώς και την προσφορά δημόσιων, ανοιχτών και φυτεμένων χώρων που η πόλη έχει τόσο ανάγκη. Τέλος, επιπρόσθετος στόχος αποτελεί η δημιουργία μίας κοιτίδας πολιτισμού, η οποία θα εκφράζεται μέσω ενός συγκροτήματος-τοπόσημου και ορισμένων αθλητικών εγκαταστάσεων.
