description: Given a logarithmic $1$-form on the snc locus of a log canonical surface pair $(X, D)$ over a perfect field of characteristic $p \ge 7$, we show that it extends with at worst logarithmic poles to any resolution of singularities. We also prove the analogous statement for regular differential forms, under an additional tameness hypothesis. In addition, residue and restriction sequences for tamely dlt pairs are established. We give a number of examples showing that our results are sharp in the surface case, and that they fail in higher dimensions. On the other hand, our techniques yield a new proof of the characteristic zero Logarithmic Extension Theorem in any dimension.

description: The Institute of Medicine Future of Nursing report recommended the development of more nurse leaders at every level and across all settings.  The Accountable Care Act has led to a reformed healthcare system, placing a growing demand for nurse leaders.  The doctoral prepared nurse must be able to fulfill leadership roles to educate future generations of nurses, translate research into practice, and influence organization-level research to meet federal performance indicators. Study Aim: To analyze the mentoring elements provided in the mentoring elements provided in the mentoring relationship of doctorate nurses and their correlation to leadership and political skill development. Methods:  A population-based web-based retrospective cross-sectional design was used to measure the correlation between mentoring functions provided to guide leadership and political skill development in PhD and DNP prepared nurses (n=222) identified as Jonas Nurse Scholars.  Results: A response rate of 52% (n=115) was attained; 86 (75%) were PhD and 29 (25%) were DNP prepared nurses.  The respondents were predominately female (87%) with 21% in the 25-34 age range and 57% in the 35-44 age range and 70% were Caucasian and 29% were minority.  Of the 115 respondents, 64% (n=74) had a mentor of which 62% (n=46) reported being in an informal mentoring relationship.    This cadre of PhD and DNP prepared nurses were highly experienced with 49.6 % having > 16 years of experience and 67% working either full-time or part-time regardless of graduation status.  The most frequent psychosocial mentoring functions were role modeling and learning facilitation.  The most frequent career mentoring functions were coaching and advocacy closely followed by career development facilitation and strategies and systems advice.  Leadership skill development was correlated with the coaching mentoring function (r=.30, p. < 0.05). Political skill development was correlated with the career development mentoring function (r=.34, p. < 0.005).  PhD and DNP nurses were similar on the leadership scale with a mean score of 7.92 (scale range 1-10) and political skill scale with a mean score of 5.73 (scale range 1-7).  Conclusion: Both PhD and DNP prepared nurses identified as Jonas Nurse Scholars possess leadership and political skill as measured by industry standard instruments.  Mentoring is one strategy to support and further develop leadership and political skill in the doctoral prepared nurse.

description: A concise theoretical framework, the $\textit{partial}$ Gauss-Hermite quadrature (pGHQ), is established for constructing on-node lattices of the lattice Boltzmann (LB) method under a Cartesian coordinate system. Comparing with existing approaches, the pGHQ scheme has the following advantages: $\textbf{a).}$ extremely concise algorithm, $\textbf{b).}$ unifying the constructing procedure of symmetric and asymmetric on-node lattices, $\textbf{c).}$ covering full-range quadrature degree of a given discrete velocity set. We employ it to search the local optimal and asymmetric lattices for $\left\{ {n = 3,4,5,6,7} \right\}$ moment degree equilibrium distribution discretization on range $\left[ { - 10,10} \right]$. The search reveals a surprising abundance of available lattices. Through a brief analysis, the discrete velocity set shows a significant influence on the positivity of equilibrium distributions, which is considered as one major impact to the numerical stability of the LB method. Hence the results of the pGHQ scheme lay a foundation for further investigations on improving the numerical stability of the LB method by modifying the discrete velocity set. It also worths noting that pGHQ can be extended into the entropic LB model though it was proposed for the Hermite polynomial expansion LB theory.

Reflectance modeling

description: Microfacet shading models in film and game production have long used a simple approximation to the Fresnel equations, published by Schlick in 1994. Recently a growing number of film studios have transitioned to using the full Fresnel reflectance equations in lieu of Schlick's approximation. This transition has been facilitated by Gulbrandsen's 2014 parameterization which uses reflectance and edge tint instead of eta and kappa. Our recent investigations have found some unexpected drawbacks to this approach. In this presentation, we will show that in the context of RGB rendering (still by far the most common modality in film production), the Fresnel equations are actually less physically principled than Schlick's approximation. In addition, they are less robust in practice and less amenable to authoring. Most surprisingly, as commonly used the Fresnel equations result in less accurate matches to measured materials, compared to Schlick's approximation. The presentation primarily discusses metal reflectance, since our investigations so far have focused on metals.

description: In the paper "Deformation theory of abelian categories", the last two authors proved that an abelian category with enough injectives can be reconstructed as the category of finitely presented modules over the category of its injective objects. We show a generalization of this to pretriangulated dg-categories with a left bounded non-degenerate t-structure with enough derived injectives, the latter being derived enhancements of the injective objects in the heart of the t-structure. Such dg-categories (with an additional hypothesis of closure under suitable products) can be completely described in terms of left bounded twisted complexes of their derived injectives.

description: Research on dynamical systems theory has demonstrated the vital role that higher levels of complexity play in the constructive management of complex conflicts. Requisite complexity theory proposes that there are stable individual complexity attributes that contribute to a dynamic complexity process that allows an individual to more effectively engage with complex and dynamic decision-making scenarios over time. However, to date, no research has empirically tested the relationships between these attributes and patterns of thought, affect and behavior in individuals engaging with complex tasks. This research examined the relationships between five proposed individual complexity attributes – cognitive complexity, perceived emotional complexity, tolerance for ambiguity, consideration for future consequences and behavioral repertoire – and level of integrative complexity, complexity of emotional experience and patterns of decision making while engaging with a complex conflict resolution simulation. Results provide initial support for the requisite complexity model, with cognitive complexity, perceived emotional complexity, tolerance for ambiguity and consideration for future consequences all demonstrating predictive validity for various aspects of the dynamic decision-making process. Implications for theory and practice are discussed, along with proposed avenues for future research.

description: During physical simulation of light transport, we separate materials between conductors and dielectrics. The former have a complex refractive index and are treated as opaque, the latter a real one and are treated as transparent. However, thin layers with a complex refractive index can become transparent if their thickness is small compared to the extinction coeffcient. This happens with thin metallic layers, but also with many pigments that are semiconductors: their extinction coeffcient (the imaginary part of their refractive index) is close to zero for part of the visible spectrum. Spectral effects inside these thin layers (attenuation and interference) result in dramatic color changes.

On Divergence of Decoherence Factor in Quantum Cosmology

description: To discuss the quantum to classical transition in quantum cosmology, we study the decoherence factor and the peak of the Wigner function, which respectively represent the degree of decoherence and the degree to which the classical motion of the Universe is defined, in a Robertson-Walker universe model coupled with a scalar field. It is known that the decoherence factor is divergent in some cases. This implies that perfect decoherence occurs, and classical correlation criterion fails. In this paper we discuss the divergence of the decoherence factor in some detail and obtain the constraints for decoherence factor to be convergent, making use of the arbitrariness defining the reduced density matrix. The result is discussed in connection with the arbitrariness of {\it system/environment} splitting.

description: The accurate reproduction of layered materials is an important part of physically-based rendering applications. Since no exact analytical model exists for any configuration of layer stacks, available models make approximations. In this paper, we propose to evaluate them with a numerical approach: we simulate BRDFs and BTDFs for layered materials in order to compare existing models against a common reference. We show that: (1) no single model always outperforms the others and (2) significant differences remain between simulated and modeled materials. We analyse the reasons for these discrepancies and introduce immediate corrections.

description: In this work, we experimentally report the acoustic realization the two-dimensional (2D) Su-Schrieffer-Heeger (SSH) model in a simple network of air channels. We analytically study the steady state dynamics of the system using a set of discrete equations for the acoustic pressure, leading to the 2D SSH Hamiltonian matrix without using tight binding approximation. By building an acoustic network operating in audible regime, we experimentally demonstrate the existence of topological band gap. More supremely, within this band gap we observe the associated edge waves even though the system is open to free space. Our results not only experimentally demonstrate topological edge waves in a zero Berry curvature system but also provide a flexible platform for the study of topological properties of sound waves.

description: In this paper we demonstrate robust estimation of the model parameters of a fully-linear data-driven BRDF model from a reflectance map under known natural lighting. To regularize the estimation of the model parameters, we leverage the reflectance similarities within a material class. We approximate the space of homogeneous BRDFs using a Gaussian mixture model, and assign a material class to each Gaussian in the mixture model. Next, we compute a linear solution per material class. Finally, we select the best candidate as the final estimate. We demonstrate the efficacy and robustness of our method using the MERL BRDF database under a variety of natural lighting conditions.

description: We consider a participatory budgeting problem in which each voter submits a proposal for how to divide a single divisible resource (such as money or time) among several possible alternatives (such as public projects or activities) and these proposals must be aggregated into a single aggregate division. Under $\ell_1$ preferences -- for which a voter's disutility is given by the $\ell_1$ distance between the aggregate division and the division he or she most prefers -- the social welfare-maximizing mechanism, which minimizes the average $\ell_1$ distance between the outcome and each voter's proposal, is incentive compatible (Goel et al. 2016). However, it fails to satisfy the natural fairness notion of proportionality, placing too much weight on majority preferences. Leveraging a connection between market prices and the generalized median rules of Moulin (1980), we introduce the independent markets mechanism, which is both incentive compatible and proportional. We unify the social welfare-maximizing mechanism and the independent markets mechanism by defining a broad class of moving phantom mechanisms that includes both. We show that every moving phantom mechanism is incentive compatible. Finally, we characterize the social welfare-maximizing mechanism as the unique Pareto-optimal mechanism in this class, suggesting an inherent tradeoff between Pareto optimality and proportionality.

The observable would be the node only. In this letter we critically analyze this scenario.

description: A way to assess rare aircraft incidents (e.g., runway excursion) is to identify contributing factors (e.g., late braking, long landing, inappropriate flare, unstable approach) and to build a dependency tree (e.g., long landing may be the result of an unstable approach not followed by a go around) that describes the causality between these factors. Probabilities are then fed into such models in order to evaluate the assessed risk. When estimating such probabilities, many sources can be of interest. Airlines have access to the comprehensive flight data records of their fleet; manufacturers push to collect data for the aircraft they build; air traffic control log radar tracks. Albeit not as complete as other flight data records, Mode S data is very attractive, esp. for academics, as the data is open, may be published without obfuscation and offers reproducible results to the community. Mode S also provides an indiscriminate source of information (not limited to an airline or to an aircraft type) that is of great help for putting in context flights matching unusual patterns. We propose to discuss the advantages and limitations of an analysis based only on Mode S data with a case study around the runway excursion risk assessment.

description: This study explored the ways in which the racial identities and lived experiences of Black male K-12 public and independent school leaders inform their professional lives and leadership. Through a qualitative phenomenological study, use of online descriptive survey, and in-depth semi-structured interviews, including the use of visual elicitation methods, with 14 Black male school leaders from across the United States, this research study provided structural and textural descriptions as well as a synthesis of meanings and essence of the experience and phenomenon of Black male K-12 school building-level leadership. This can be summarized as: (a) growing up as a Black boy; (b) leadership as ministry; (c) when a Black man is in the principal’s office; and (d) safeguarding the village. The research expands understanding of paradigms of critical race leadership and disrupts the normative educational leadership axiology. These leaders developed a range of strategies that enabled them to navigate the multidimensional aspects of their racial identity within a dominant White-racialized education system. Additionally, their articulation of action-oriented social justice leadership was influenced by their personal lived experiences, values, and sense of community.

description: A research program was initiated at the Highland Valley Copper mine in 1996 to test the effectiveness of biosolids application as a potential reclamation treatment on different waste materials and to assess the possible benefits and deleterious effects of the application of biosolids to waste areas. The test sites were located on tailings and waste rock areas of Bethlehem property. Two different application methods were tested: topdressing with biosolids at application rates ranging from 25 to 50 dry tonnes per hectare and incorporation of biosolids at application rates ranging from 100 to 200 dry tonnes per hectare. Control treatments were included in the study design to allow for comparison of biosolids treatment with standard reclamation treatments using annual application of chemical fertilizers during the first three to four years of vegetation establishment. Sites selected for the trial locations represented challenging reclamation sites where a till capping or other soil amendment had been prescribed to improve the water holding capacity of the sites. The biosolids research program included monitoring to assess the changes to soil, ground water and vegetation chemistry, and effects on vegetation cover and biomass production on the treated sites. Chemical data will be presented to identify chemical impacts to soil, water and foliar chemistry attributable to the application of biosolids.

description: Many motion tracking systems require solving inverse problem to compute the tracking result from original sensor measurements, such as images from cameras and signals from receivers. For real-time motion tracking, such typical solutions as the Gauss-Newton method for solving their inverse problems need an initial value to optimize the cost function through iterations. A powerful initializer is crucial to generate a proper initial value for every time instance and, for achieving continuous accurate tracking without errors and rapid tracking recovery even when it is temporally interrupted. An improper initial value easily causes optimization divergence, and cannot always lead to reasonable solutions. Therefore, we propose a new initializer based on random-forest to obtain proper initial values for efficient real-time inverse problem computation. Our method trains a random-forest model with varied massive inputs and corresponding outputs and uses it as an initializer for runtime optimization. As an instance, we apply our initializer to IM3D, which is a real-time magnetic 3D motion tracking system with multiple tiny, identifiable, wireless, occlusion-free passive markers (LC coils). During run-time, a proper initial value is obtained from the initializer based on sensor measurements, and the system computes each position of the actual markers and poses by solving the inverse problem through an optimization process in real-time. We conduct four experiments to evaluate reliability and performance of the initializer. Compared with traditional or naive initializers (i.e., using a static value or random values), our results show that our proposed method provides recovery from tracking loss in a wider range of tracking space, and the entire process (initialization and optimization) can run in real-time.

description: In a recent Letter [T. Dornheim et al., Phys. Rev. Lett. 121, 255001 (2018)] we have presented the first ab initio results for the dynamic structure factor $S(\mathbf{q},ω)$ of the uniform electron gas for conditions ranging from the warm dense matter regime to the strongly correlated electron liquid. This was achieved on the basis of exact path integral Monte Carlo data by stochastically sampling the dynamic local field correction $G(\mathbf{q},ω)$. In this paper, we introduce in detail this new reconstruction method and provide several practical demonstrations. Moreover, we thoroughly investigate the associated imaginary-time density--density correlation function $F(\mathbf{q},τ)$. The latter also gives us access to the static density-response function $χ(\mathbf{q})$ and static local field correction $G(\mathbf{q})$, which are compared to standard dielectric theories like the widespread random phase approximation. In addition, we study the high-frequency limit of $G(\mathbf{q},ω)$ and provide extensive new results for the dynamic structure factor for different densities and temperatures. Finally, we discuss the implications of our findings for warm dense matter research and the interpretation of experiments.

description: Bestvina and Feighn showed that a morphism S --> T between two simplicial trees that commutes with the action of a group G can be written as a product of elementary folding operations. Here a more general morphism between simplicial trees is considered, which allow different groups to act on S and T. It is shown that these morphisms can again be written as a product of elementary operations: the Bestvina-Feighn folds plus the so-called `vertex morphisms'. Applications of this theory are presented. Limits of infinite folding sequences are considered. One application is that a finitely generated inaccessible group must contain an infinite torsion subgroup.

description: The bat algorithm (BA) has been shown to be effective to solve a wider range of optimization problems. However, there is not much theoretical analysis concerning its convergence and stability. In order to prove the convergence of the bat algorithm, we have built a Markov model for the algorithm and proved that the state sequence of the bat population forms a finite homogeneous Markov chain, satisfying the global convergence criteria. Then, we prove that the bat algorithm can have global convergence. In addition, in order to enhance the convergence performance of the algorithm, we have designed an updated model using the dynamical system theory in terms of a dynamic matrix, and the parameter ranges for the algorithm stability are then obtained. We then use some benchmark functions to demonstrate that BA can indeed achieve global optimality efficiently for these functions.

description: Numerical evidence is given for non-ergodic (non-mixing) behavior, exhibiting ideal transport, of a simple non-integrable many-body quantum system in the thermodynamic limit, namely kicked $t-V$ model of spinless fermions on a ring. However, for sufficiently large kick parameters $t$ and $V$ we recover quantum ergodicity, and normal transport, which can be described by random matrix theory.

description: Supernumerary Robotic Limbs (SRLs) can make physical activities easier, but require cooperation with the operator. To improve cooperation between the SRLs and the operator, the SRLs can try to predict the operator's intentions. A way to predict the operator's intentions is to use his/her Facial Expressions (FEs). Here we investigate the mapping between FEs and Supernumerary Robotic Arms (SRAs) commands (e.g. grab, release). To measure FEs, we used a optical sensor-based approach (here inside a HMD). The sensors data are fed to a SVM able to predict FEs. The SRAs can then carry out commands by predicting the operator's FEs (and arguably, the operator's intention). We ran a data collection study (N=10) to know which FEs assign to which robotic arm commands in a Virtual reality Environment (VE). We researched the mapping patterns by (1) performing an object reaching - grasping - releasing task using ''any'' FEs; (2) analyzing sensors data and a self-reported FE questionnaire to find the most common FEs used for a given command; (3) classifying the FEs in FEs groups. We then ran another study (N=14) to find the most effective combination of FEs groups / SRAs commands by recording task completion time. As a result, we found that the optimum combinations are: (i) Eyes + Mouth for grabbing / releasing; and (ii) Mouth for extending / contracting the arms (i.e. a along the forward axis).

Focusing and the Holographic Hypothesis

description: The ``screen mapping" introduced by Susskind to implement 't Hooft's holographic hypothesis is studied. For a single screen time, there are an infinite number of images of a black hole event horizon, almost all of which have smaller area on the screen than the horizon area. This is consistent with the focusing equation because of the existence of focal points. However, the {\it boundary} of the past (or future) of the screen obeys the area theorem, and so always gives an expanding map to the screen, as required by the holographic hypothesis. These considerations are illustrated with several axisymmetric static black hole spacetimes.

description: We study local and non-local Polyakov Nambu-Jona-Lasinio models and analyze their respective phase transition diagram. We construct hybrid stars using the zero temperature limit of the local and non-local versions of Nambu-Jona-Lasinio model for quark matter and the modern GM1(L) parametrization of the non-linear relativistic mean field model for hadronic matter. We compare our models with data from PSR J1614-2230 and PSR J0343+0432 and also from GW170817 and its electromagnetic counterpart GRB170817A and AT2017gfo. We study observational signatures of the appearance of a mixed phase as a result of modeling a phase transition that mimics the Gibbs formalism and compare the results with the sharp first-order phase transition obtained using the Maxwell construction. We also study in detail the $g$-mode associated with discontinuities in the equation of state, and calculate non-radial oscillation modes using relativistic Cowling approximation.

Deformation of Okamoto-Painlevé Pairs and Painlevé equations

description: In this paper, we introduce the notion of generalized rational Okamoto-Painlevé pair (S, Y) by generalizing the notion of the spaces of initial conditions of Painlevé equations. After classifying those pairs, we will establish an algebro-geometric approach to derive the Painlevé differential equations from the deformation of Okamoto-Painlevé pairs by using the local cohomology groups. Moreover the reason why the Painlevé equations can be written in Hamiltonian systems is clarified by means of the holomorphic symplectic structure on S - Y. Hamiltonian structures for Okamoto-Painlevé pairs of type $\tilde{E}_7 (= P_{II})$ and $\tilde{D}_8 (= P_{III}^{\tilde{D}_8})$ are calculated explicitly as examples of our theory.

description: Macbeath gave a formula for the number of fixed points for each non-identity element of a cyclic group of automorphisms of a compact Riemann surface in terms of the universal covering transformation group of the cyclic group. We observe that this formula generalizes to determine the fixed-point set of each non-identity element of a cyclic group of automorphisms acting on a closed non-orientable surface with one exception; namely, when this element has order 2. In this case the fixed-point set may have simple closed curves (called ovals) as well as fixed points. In this note we extend Macbeath's results to include the number of ovals and also determine whether they are twisted or not.
