description: Rendering photo-realistic image sequences using path tracing and Monte Carlo integration often requires sampling a large number of paths to get converged results. In the context of rendering multiple views or animated sequences, such sampling can be highly redundant. Several methods have been developed to share sampled paths between spatially or temporarily similar views. However, such sharing is challenging since it can lead to bias in the final images. Our contribution is a Monte Carlo sampling technique which generates paths, taking into account several cameras. First, we sample the scene from all the cameras to generate hit points. Then, an importance sampling technique generates bouncing directions which are shared by a subset of cameras. This set of hit points and bouncing directions is then used within a regular path tracing solution. For animated scenes, paths remain valid for a fixed time only, but sharing can still occur between cameras as long as their exposure time intervals overlap. We show that our technique generates less noise than regular path tracing and does not introduce noticeable bias.

description: The purpose of this study was to highlight the positions, political objectives and how Ecologist-Greens tried to direct their political campaign in the parliamentary elections of October 2009. To accomplish this, after initially outlining the origins of the ecological movement, i used the theory of discourse analysis of Laclau & Mouffe in order to demonstrate the functions of certain key signifiers in the construction of green word. Through this process the strategy of the party is outlined, its internal contradictions and it’s ongoing effort to establish itself as compact political party in a climate of polarization which undermines the it’s political survival.

description: Modern interactive rendering can rely heavily on precomputed static lighting on surfaces and in volumes. Scattering from volumetric media can be similarly treated using precomputation, but transport from volumes onto surfaces is typically ignored here. We propose a compact, efficient method to simulate volume-to-surface transport during lighting precomputation . We leverage a novel model of the spherical impulse response of light scattered (and attenuated) in volumetric media to simulate light transport from volumes onto surfaces with simple precomputed lookup tables. These tables model the impulse response as a function of distance and angle to the light and surfaces. We then remap the impulse responses to media with arbitrary, potentially heterogeneous scattering parameters and various phase functions. Moreover, we can compose our impulse response model to treat multiple scattering events in the volume (arriving at surfaces). We apply our method to precomputed volume-to-surface light transport in complex scenes, generating results indistinguishable from ground truth simulations. Our tables allow us to precompute volume-to-surface transport orders of magnitude faster than even an optimized path tracing-based solution would.

High-energy resolution in this study helps to reveal particle-hole asymmetry in the excitation spectra of CaRuO3 in contrast to that in SrRuO3. In addition, we observe signature of phonon excitations in the photoemission spectra of CaRuO3 at finite temperatures while these are weak in SrRuO3.

A Window on the Valley: A Study of the Free Black Community of Winchester and Frederick County, Virginia, 1785 - 1860
Creators: name: Ebert, Rebecca Aleene
Publisher: name: Digital Repository at the University of Maryland
Year: 1986

description: This is the first substantial study which has been undertaken on the
free black community of Winchester and Frederick County, Virginia.
It explains who the free blacks were, where they lived, how they
obtained their freedom, how they maintained it, how they constituted a
community, and how they interacted with slaves and whites.
These free blacks engaged in a variety of occupations; they did
not dominate any one field of employment. The population was predominately
young and individuals and families appeared to remain stable throughout
the era studied. In later years, female -headed households became
more common.
The records available on free blacks in Frederick County are limited.
Therefore, this investigation has been primarily through official records
generated by the local courts and state government. They have, however,
been sufficient to suggest a growing and viable group that was accepted
by and contributed to the larger community throughout the ante-bellum years.
Challenges in Implementing Human Resource Analytics

description: Digital transformation and artificial intelligence encourage HR professionals to concentrate on HR technology in order to develop skills and competencies for strategic advantage. Nowadays, HR professionals are involved in strategic decision-making as well as administrative responsibilities, necessitating the application of data analytics in human resources. HR analytics is a data-driven method that enables human resources professionals to make educated, evidence-based choices. An evidence-based choice can only be made with data, and it is difficult for HR professionals to translate HR data into strategic value. To properly integrate HR Analytics, HR professionals must first understand the problems they experience throughout implementation and application. This study seeks to identify the issues that HR professionals experience while applying HR analytics and to provide realistic solutions. HR has considerable hurdles in deploying HR analytics, including a lack of data analytics expertise, privacy and compliance, data variety, and technologies, among other things.

We find that merons can nucleate both inside and at the edge of the dots. In addition to these merons, our results show that electron density modulations can be also present inside the dots. An edge meron appears to have approximately a half integer winding number.

description: In the present paper, we first give a detailed study on the pQCD corrections to the leading-twist part of BSR. Previous pQCD corrections to the leading-twist part derived under conventional scale-setting approach up to ${\cal O}(α_s^4)$-level still show strong renormalization scale dependence. The principle of maximum conformality (PMC) provides a systematic way to eliminate conventional renormalization scale-setting ambiguity by determining the accurate $α_s$-running behavior of the process with the help of renormalization group equation. Our calculation confirms the PMC prediction satisfies the standard renormalization group invariance, e.g. its fixed-order prediction does scheme-and-scale independent. In low $Q^2$-region, the effective momentum of the process is small and to have a reliable prediction, we adopt four low-energy $α_s$ models to do the analysis. Our predictions show that even though the high-twist terms are generally power suppressed in high $Q^2$-region, they shall have sizable contributions in low and intermediate $Q^2$ domain. By using the more accurate scheme-and-scale independent pQCD prediction, we present a novel fit of the non-perturbative high-twist contributions by comparing with the JLab data.

description: Computing power is still the limiting factor in photorealistic real-time rendering. Foveated rendering improves perceived quality by focusing the rendering effort on where the user is looking at. Applying foveated rendering to real-time path tracing where we must work on a very small number of samples per pixel introduces additional challenges; the rendering result is thoroughly noisy and sparse in the periphery. In this paper we demonstrate foveated real-time path tracing system and propose a novel Visual-Polar space in which both real-time path tracing and denoising is done before mapping to screen space. When path tracing a regular grid of samples in Visual-Polar space, the screen space sample distribution follows the human visual acuity model, making both the rendering and denoising 2:5x faster with similar perceived quality. In addition, when using Visual- Polar space, primary rays stay more coherent, leading to improved utilization of the GPU resources and, therefore, making ray traversal 1.3 - 1.5x faster. Moreover, Visual-Polar space improves 1 sample per pixel denoising quality in the fovea. We show that Visual-Polar based path tracing enables real-time rendering for contemporary virtual reality devices even without dedicated ray tracing hardware acceleration.

description: Fumonisin B1 (FB1) and beauvericin (BEA) are fusariotoxins found to co-exist in food and feed commodities. The aim of this study is to evaluate the individual and combined effects of FB1 and BEA on bovine granulosa cell proliferation and steroid production. Granulosa cells (GC) from small bovine follicles (1-5 mm) were cultured for 48 hours in 10% fetal bovine serum followed by 48 hours in a serum-free medium containing 500 ng/ml of testosterone (as an estradiol precursor), 30 ng/ml of FSH and 30 ng/ml of IGF-I with and without FB1 (3 µM) and BEA (3 µM). At the end of the experiment, the numbers of GC were determined using a Coulter counter (Beckman Coulter, USA) and concentrations of progesterone and estradiol in the culture medium were determined by radioimmunoassay. FB1 and BEA, both individually and in combination, showed an inhibitory effect (P < 0.05) on GC proliferation. The number of GC decreased by 17.7%, 54.2% and 61.0% after exposure to FB1 (3 µM), BEA (3 µM) and FB1 (3 µM) plus BEA (3 µM) respectively. FB1 (3 µM) had no effect (P > 0.05) on estradiol and progesterone production, whereas BEA (3 µM), both alone and in combination with FB1 (3 µM), was found to decrease (P < 0.001) the production of both steroids drastically. In conclusion, this in vitro study indicates that FB1 and BEA, both individually and in combination, may affect GC proliferation to different extents and shows the drastic inhibitory effects of BEA on steroid production.

description: Native Americans make up only 2% of the population, yet have one of the highest suicide rates of any ethnic or racial group in the United States. High suicide rates in Native American communities can be attributed to a number of factors including historical trauma, genocide, and lack of access to healthcare. The purpose of this study was to explore the experiences of Native Americans who had a nonfatal suicide attempt and their encounter with healthcare providers prior to receiving the Caring Contacts intervention.
description: Five hundred and fifty-four Native American participants provided responses to three qualitative questions from the Client Satisfaction Questionnaire- 8 prior to receiving a culturally adapted suicide intervention. Thematic Analysis was used to interpret and identify patterns of meaning in the words of the Native participants. Through team analysis of the transcripts, an understanding of the participant’s experiences was developed. Thematic Analysis, with its idiographic focus, allowed for insight into the Native participants’ experience and how they make sense of their experiences as a Native person that has attempted suicide. The information provided during the baseline interviews of the Native participants allowed for extrapolation of meaningful themes related to Communication (subthemes: Counseling, Characteristics of Communication, and Role of Staff Communication), Access (subthemes: Care Received, Access to Medications, and Access to Services), and Connection (subthemes: Provider-Patient Relationship, Coping Skills, Provider Consistency, and Culturally Congruent Care). The themes informed the patient perspective of the healthcare received.
description: Healthcare workers, specifically nurses, may be the first person a Native person engages with post suicide attempt. It is imperative that nurses and all healthcare workers provide care to the Native patient after a suicide attempt that is culturally sensitive and void of stigma associated with suicide, race, ethnicity, and culture.

description: Nowadays, there is a growing demand for inclusive education of both children with and without Special Learning Disabilities in the mainstream school, while the deficiencies in teachers’ knowledge on issues of Special Education, hinder their proper addressing of those educational specificities. Consequently, considerable efforts have been made recently by various institutional and non-institutional programs with the aim of improving and strengthening the teachers’ ability to overcome their weaknesses as well as enhancing and updating their skills via training (Hatzidimou, 2011). The purpose of this study is to investigate whether and how training reinforces the role of the teacher in order to be more effective in inclusive education of both students with and without Special Learning Disabilities. In order to achieve this purpose, are examined some views of University Professors, who are specialized in Special Education and in particular on Special Learning Disabilities and have participated in relevant training programs as trainers. Furthermore, are studied views of primary school teachers, who have been trained on Special Education and whose students with and without Specific Learning Disabilities are taught inclusively.

description: Going beyond the simplified gluonic cascades, we introduce both gluon and quark degrees of freedom for partonic cascades inside the medium. We then solve the set of coupled evolution equations numerically with splitting kernels calculated for static, exponential, and Bjorken expanding media to arrive at medium-modified parton spectra for quark and gluon initiated jets. Using these, we calculate the inclusive jet $R_{AA}$ where the phenomenologically driven combinations of quark and gluon jet fractions are included. Then, the rapidity dependence of the jet $R_{AA}$ is examined. We also study the path-length dependence of jet quenching for different types of expanding media by calculating the jet $v_2$. Additionally, we study the sensitivity of observables on effects from nuclear modification of parton distribution functions, vacuum-like emissions in the plasma, and the time of the onset of the quenching. All calculations are compared with recently measured data.

description: We show that the existence of cosmic strings can be strongly constrained by the next generation of gravitational lensing surveys at radio frequencies. We focus on cosmic string loops, which simulations suggest would be far more numerous than long (horizon-sized) strings. Using simple models of the loop population and minimal assumptions about the lensing cross section per loop, we estimate the optical depth to lensing and show that extant radio surveys such as CLASS have already ruled out a portion of the cosmic string model parameter space. Future radio interferometers, such as LOFAR and especially SKA, may constrain $Gμ/c^2 < 10^{-9}$ in some regions of parameter space, outperforming current constraints from pulsar timing and the CMB by up to two orders of magnitude. This method relies on direct detections of cosmic strings, and so is less sensitive to the theoretical uncertainties in string network evolution that weaken other constraints.

description: MicroRNAs (miRNAs) are small 21-25 nucleotide regulatory non-coding RNAs that modulate gene expression in eukaryotic organisms. miRNAs are complementary to the 3′-untranslated regions of mRNA and act as post-transcriptional regulators of gene expression, exhibiting remarkable stability in extracellular fluids such as blood. Turkey (Meleagris gallopavo) farming is a species economically relevant but the lack of efficient protocols for the evaluation of commercial turkeys prevents to measure the impact of industry practices on birds productivity and welfare. In order to identify potential molecular biomarkers for monitoring stress in turkey’s handling, we investigated by TaqMan qPCR the abundance of five circulating miRNA, namely miR-22, miR-155, miR-181a, miR-204 and miR-365, previously demonstrated to be involved in stress in chicken due to feed deprivation. Road transportation related procedures were selected as stressful model for this study. The serum of twenty healthy animals was collected before and after 2h transportation. Our results demonstrated that miR-22, miR-155 and miR-365 are statistically more expressed after road transportation. Receiver-operator characteristics (ROC) analysis was used to estimate the diagnostic value of these miRNAs to evaluate the stress in animals. The serum level of miR-22, miR-155 and miR-365 can discriminate stressed from non-stressed animals with an AUC=0.763, 0.710 and 0.704, respectively, and the average expression of their combination has the same specificity (AUC=0.745). miR-22, miR-155 and miR-365 are stress-specific markers and can be considered as suitable biomarkers to identify turkeys stressed by road transportation.

description: In this paper we study the cosmological CPT-violation and its implications in baryo/leptogenesis and CMB polarization. We propose specifically a variant of the models of gravitational leptogenesis. By performing a global analysis with the Markov Chain Monte Carlo (MCMC) method, we find the current CMB polarization observations from the three-year WMAP (WMAP3) and the 2003 flight of BOOMERANG (B03) data provide a weak evidence for our model. However to verify and especially exclude this type of mechanism for baryo/leptogenesis with cosmological CPT-violation, the future measurements on CMB polarization from PLANCK and CMBpol are necessary.

description: We discuss high-order calculations in perturbative effective field theory for fermions at low energy scales. The Fermi-momentum or $k_{\rm F} a_s$ expansion for the ground-state energy of the dilute Fermi gas is calculated to fourth order, both in cutoff regularization and in dimensional regularization. For the case of spin one-half fermions we find from a Bayesian analysis that the expansion is well-converged at this order for ${| k_{\rm F} a_s | \lesssim 0.5}$. Further, we show that Pad{é}-Borel resummations can improve the convergence for ${| k_{\rm F} a_s | \lesssim 1}$. Our results provide important constraints for nonperturbative calculations of ultracold atoms and dilute neutron matter.

A structure conduct performance assessment of alternative Canada-United States Air Services Agreements
Creators: name: Roberts, Tony Selwyn
Publisher: name: University of British Columbia
Year: 2009

description: Canada and the United States have the largest, bilateral trade relationship of any two nations. Fittingly, they also exchange the largest volume of international air travellers of any pair of countries. The terms under which Canada-United States air transportation are provided are set forth in the Canada-United States Bilateral Air Services Agreement. The current Agreement was founded upon the consumer demands and industry operating practices that prevailed in 1966. Although the Agreement was substantially modified in 1974, the essence of the regime has been rendered obsolete by the developments of transborder airline market characteristics. Canada and the United States have recognised that a new bilateral air services agreement is a necessity. Three general strategies have been proposed as the bases for a new regime: the specified rights option, the open border option, and the cabotage rights option. Specified rights is the genre of the current regime: all routes having entry strictly controlled. The open border option would entail complete freedom for either country’s carriers to contest all transborder routes. Cabotage rights allow carriers to contest any market within or between the two countries. A new agreement has yet to be achieved. The delay in finding an acceptable scheme has been the difficulty in meeting both major objectives for the new policy: efficiency and equity. This report examines the alternative schemes for a new Canada-United States air services regime. The structure-conduct-performance paradigm of industrial analysis is utilised to evaluate the nature of the distribution of benefits that would arise following the adoption of the various alternatives. The report concludes that the adoption of a phased-in, open border regime would best meet the twin objectives of efficiency enhancement and equity of opportunity.

description: Consider an elliptic self-adjoint pseudodifferential operator $A$ acting on $m$-columns of half-densities on a closed manifold $M$, whose principal symbol is assumed to have simple eigenvalues. Relying on a basis of pseudodifferential projections commuting with $A$, we construct an almost-unitary pseudodifferential operator that diagonalizes $A$ modulo an infinitely smoothing operator. We provide an invariant algorithm for the computation of its full symbol, as well as an explicit closed formula for its subprincipal symbol. Finally, we give a quantitative description of the relation between the spectrum of $A$ and the spectrum of its approximate diagonalization, and discuss the implications at the level of spectral asymptotics.

description: We obtain the corrections in $1/n$ and in $1/\ln n$ ($n$ is the principal quantum number of the bound state) of the decay constants of scalar and pseudoscalar currents in two and four dimensions in the large $N_c$. We obtain them from the operator product expansion provided a model for the large $n$ mass spectrum is given. In the two-dimensional case the spectrum is known and the corrections obtained in this paper are model independent. We confirm these results by confronting them with the numerical solution of the 't Hooft model. We also consider a model at finite $N_c$ and obtain the associated decay constants that are consistent with perturbation theory. This example shows that that the inclusion of perturbative corrections, or finite $N_c$ effects, to the OPE does not constrain the slope of the Regge trajectories, which remain a free parameter for each different channel.

description: Dubbing puppet videos to make the characters (e.g. Kermit the Frog) convincingly speak a new speech track is a popular activity with many examples of well-known puppets speaking lines from films or singing rap songs. But manually aligning puppet mouth movements to match a new speech track is tedious as each syllable of the speech must match a closed-open-closed segment of mouth movement for the dub to be convincing. In this work, we present two methods to align a new speech track with puppet video, one semi-automatic appearance-based and the other fully-automatic audio-based. The methods offer complementary advantages and disadvantages. Our appearance-based approach directly identifies closed-open-closed segments in the puppet video and is robust to low-quality audio as well as misalignments between the mouth movements and speech in the original performance, but requires some manual annotation. Our audio-based approach assumes the original performance matches a closed-open-closed mouth segment to each syllable of the original speech. It is fully automatic, robust to visual occlusions and fast puppet movements, but does not handle misalignments in the original performance. We compare the methods and show that both improve the credibility of the resulting video over simple baseline techniques, via quantitative evaluation and user ratings.

Publisher: name: Zenodo
Year: 2024

description: The Indian railway system is widely used across the country. It ensures that individuals of all socioeconomic backgrounds may travel in style. It's great for moving jute, cement, gasoline, and other bulky items from one end of the nation to the other. Using an exponential growth technique this research analyzes the financial performance of Indian Railways from 2019 to 2023, highlighting trends in revenue, expenditure, profitability, and financial sustainability. All of the information for this research came from publicly available sources, such as the Indian Railways' annual reports. Through quantitative analysis of five years of data, this study aims to provide insights into the operational efficiencies and challenges faced by Indian Railways. The findings indicate significant trends in freight and passenger earnings, subsidies, and investment requirements, informing policymakers and stakeholders of the railway's financial health and future directions.
Wormhole calculus without averaging from $O(N)^{q-1}$ tensor model

description: The SYK model has a wormhole-like solution after averaging over the fermionic couplings in the nearly $AdS_2$ space. Even when the couplings are fixed the contribution of these wormholes continues to exist and new saddle points appear which are interpreted as "half-wormholes". In this paper, we will study the fate of these wormholes in a model without quenched disorder namely a tensor model with $O(N)^{q-1}$ gauge symmetry whose correlation function and thermodynamics in the large $N$ limit are the same as that of the SYK model. We will restate the factorization problem linked with the wormhole threaded Wilson operator, in terms of global charges or non-trivial cobordism classes associated with disconnected wormholes. Therefore for the partition function to factorize especially at short distances, there must exist certain topological defects which break the global symmetry associated with wormholes and make the theory devoid of global symmetries. We will interpret these wormholes with added topological defects as our "half-wormholes". We will also comment on the late time behavior of the spectral form factor, particularly its leading and sub-leading order contributions coming from higher genus wormholes in the gravitational sector. Finally we will show how, the other non-trivial saddles from "half-wormhole" dominate and give rise to unusual thermodynamics in the bulk sector due to non-perturbative effects.

Implementing One-Click Caustics in Corona Renderer
Creators: name: Šik, Martin
name: Krivánek, Jaroslav
Publisher: name: The Eurographics Association
Year: 2019

description: This paper describes the implementation of a fully automatic caustics rendering solution in Corona Renderer. The main requirement is that the technique be completely transparent to the user, should not need any parameter setting at all, and be fully integrated into the interactive and progressive rendering workflow. We base our approach on an efficient subset of the vertex connection and merging algorithm, specifically a multiple importance sampling combination of path tracing and photon mapping. We rely on Metropolis sampling to guide photon paths into the relevant parts of the scene. While these underlying ideas have appeared in existing research work, numerous previously unaddressed issues and edge cases arise when one applies these ideas in practice. These include unreliable convergence of the Metropolis sampler in scenes with many light sources of different sizes and intensities, the ''caustic in a stadium'' problem (i.e., efficient rendering of small caustics in extremely large scenes), etc. We present the solutions we have developed to address such issues, yielding what we call ''one-click caustics rendering''. User feedback suggests that our approach substantially improves usability over methods previously implemented in comercially available software, all requiring the user to set various technical parameters.

description: We compute the probability density distribution of maxima for a scalar random field in the presence of local non-gaussianities. The physics outcome of this analysis is the following. If we focus on maxima whose curvature is larger than a certain threshold for gravitational collapse, our calculations illustrate how the fraction of the Universe's mass in the form of primordial black holes (PBHs) changes in the presence of local non-gaussianities. We find that previous literature on the subject exponentially overestimate, by many orders of magnitude, the impact of local non-gaussianities on the PBH abundance. We explain the origin of this discrepancy, and conclude that, in realistic single-field inflationary models with ultra slow-roll, one can obtain the same abundance found with the gaussian approximation simply changing the peak amplitude of the curvature power spectrum by no more than a factor of two. We comment about the relevance of non-gaussianities for second-order gravitational waves.

description: We propose a deep-learning based method for the removal of shades, projected shadows and highlights from a single picture of a quasi-planar surface captured in natural lighting conditions with any kind of camera device. To achieve this, we train an encoder-decoder to process physically based materials, rendered under various lighting conditions, to infer its spatially-varying albedo. Our network processes relatively small image tiles (512x512 pixels) and we propose a solution to handle larger image resolutions by solving a Poisson system across these tiles.

Cellular Dynamical Mean Field Theory of the Periodic Anderson Model

description: We develop a cluster dynamical mean field theory of the periodic Anderson model in three dimensions, taking a cluster of two sites as a basic reference frame. The mean field theory displays the basic features of the Doniach phase diagram: a paramagnetic Fermi liquid state, an antiferromagnetic state and a transition between them. In contrast with spin density wave theories, the transition is accompanied by a large increase of the effective mass everywhere on the Fermi surface and a substantial change of the Fermi surface shape across the transition. To understand the nature and the origin of the phases near the transition, we investigate the paramagnetic solution underlying the antiferromagnetic state, and identify the transition as a point where the $f$ electrons decouple from the conduction electrons undergoing an orbitally selective Mott transition. This point turns out to be intimately related to the two impurity Kondo model quantum critical point. In this regime, non local correlations become important and result in significant changes in the photoemission spectra and the de Haas-van Alphen frequencies. The transition involves considerable $f$ spectral weight transfer from the Fermi level to its immediate vicinity, rather than to the Hubbard bands as in single site DMFT.
