description: This paper introduces a new approach for the automated reconstruction - reassembly of fragmented objects having one surface near to plane, on the basis of the 3D representation of their constituent fragments. The whole process starts by 3D scanning of the available fragments. The obtained representations are properly processed so that they can be tested for possible matches. Next, four novel criteria are introduced, that lead to the determination of pairs of matching fragments. These criteria have been chosen so as the whole process imitates the instinctive reassembling method dedicated scholars apply. The first criterion exploits the volume of the gap between two properly placed fragments. The second one considers the fragments' overlapping in each possible matching position. Criteria 3,4 employ principles from calculus of variations to obtain bounds for the area and the mean curvature of the contact surfaces and the length of contact curves, which must hold if the two fragments match. The method has been applied, with great success, both in the reconstruction of objects artificially broken by the authors and, most importantly, in the virtual reassembling of parts of wall paintings belonging to the Mycenaic civilization (c. 1300 B.C.), excavated in a highly fragmented condition in Tyrins, Greece.

description: The resolution of the Maxwell's demon paradox linked thermodynamics with information theory through information erasure principle. By considering a demon endowed with a Turing-machine consisting of a memory tape and a processor, we attempt to explore the link towards the foundations of statistical mechanics and to derive results therein in an "operational" manner. Here, we present a derivation of the Boltzmann distribution in equilibrium as an example, without hypothesizing the principle of maximum entropy. Further, since the model can be applied to non-equilibrium processes, in principle, we demonstrate the dissipation-fluctuation relation to show the possibility in this direction.

description: We consider Bayesian estimation of a $p\times p$ precision matrix, when $p$ can be much larger than the available sample size $n$. It is well known that consistent estimation in such ultra-high dimensional situations requires regularization such as banding, tapering or thresholding. We consider a banding structure in the model and induce a prior distribution on a banded precision matrix through a Gaussian graphical model, where an edge is present only when two vertices are within a given distance. For a proper choice of the order of graph, we obtain the convergence rate of the posterior distribution and Bayes estimators based on the graphical model in the $L_{\infty}$-operator norm uniformly over a class of precision matrices, even if the true precision matrix may not have a banded structure. Along the way to the proof, we also compute the convergence rate of the maximum likelihood estimator (MLE) under the same set of condition, which is of independent interest. The graphical model based MLE and Bayes estimators are automatically positive definite, which is a desirable property not possessed by some other estimators in the literature. We also conduct a simulation study to compare finite sample performance of the Bayes estimators and the MLE based on the graphical model with that obtained by using a Cholesky decomposition of the precision matrix. Finally, we discuss a practical method of choosing the order of the graphical model using the marginal likelihood function.

description: (Abridged) The rotational evolution of isolated neutron stars is dominated by the magnetic field anchored to the solid crust of the star. Assuming that the core field evolves on much longer timescales, the crustal field evolves mainly though Ohmic dissipation and the Hall drift, and it may be subject to relatively rapid changes with remarkable effects on the observed timing properties. We investigate whether changes of the magnetic field structure and strength during the star evolution may have observable consequences in the braking index, which is the most sensitive quantity to reflect small variations of the timing properties that are caused by magnetic field rearrangements. By performing axisymmetric, long-term simulations of the magneto-thermal evolution of neutron stars with state-of-the-art microphysical inputs, we find that the effect of the magnetic field evolution on the braking index can be divided into three qualitatively different stages depending on the age and the internal temperature: a first stage that may be different for standard pulsars (with n~3) or low field neutron stars that accreted fallback matter during the supernova explosion (systematically n<3); in a second stage, the evolution is governed by almost pure Ohmic field decay, and a braking index n>3 is expected; in the third stage, at late times, when the interior temperature has dropped to very low values, Hall oscillatory modes in the neutron star crust result in braking indices of high absolute value and both positive and negative signs. Models with strong (1e14 G) multipolar or toroidal components, even with a weak (~1e12 G) dipolar field are consistent with the observed trend of the timing properties.

description: We report on observations of the optical variability of the radio-loud, narrow-line Seyfert 1 galaxy J0948+0022 on time scales ranging from minutes to years. Implications regarding recent suggestions that the object may constitute a prototype for an emerging class of blazar-like objects similar to FSRQs are discussed. The optical microvariability observed for J0948+0022 is found to be similar to that found for a typical LBL blazar. Based on observations of J0948+0022 in a flaring state and a significantly lower state, one can demonstrate that these rapid variations are most likely originating in the relativistic jet and not in the accretion disk

Educators' Perspectives Associated with School Garden Programs in Clark County, Nevada: Practices, Resources, Benefits and Barriers.
Creators: name: Murakami, Tomomi

Year: 2015

description: School garden programs have been utilized in the U.S. since their introduction at the end of the 19th century. The use of school gardens and the teaching style implemented in them are dependent on individual schools and teachers. Educators' attitudes, knowledge, and motivation for a school-based gardening program are crucial to implementing comprehensive school garden programs. To move toward an expansion of garden education, it is necessary to determine the concerns, resources, benefits or barriers that educators identify regarding the utilization of gardens to teach their students. The purpose of this pilot study was to determine principals' and teachers' perceived practices, resources, benefits, and barriers to the school garden programs in Clark County Nevada. The survey was sent to 250 teachers and administrators at schools in Clark County School District (CCSD) using an electronic web site link on an invitation to participated in the survey. One hundred and nineteen educators completed the survey and were used for the data analysis. Many educators with gardens perceive that students benefit from school garden programs; however, there are factors that can be improved for the implementation of school garden programs in CCSD to be a success. Current practices and important resources needed for school gardens as well as benefits of and barriers to the school garden programs will be presented. Recommendations will assist the suitability of school gardening in the future.

digital innovation hub

description: If Digital Innovation Hubs (DIHs), including makerspaces, stand the chance to be empowered as key drivers of local innovation in Africa, then they would certainly require government support as they do not exist in isolation but rather, form parts of countries on the continent. In that light, this report digs into the activities being undertaken by innovation hubs and hub networks for their development. The interesting finding in this report are beneficial as they create awareness on the policy advocacy actions in Europe, which would be beneficial when adopted in African spaces. Lastly, the report identifies the different approaches to policy advocacy actions and puts across a recommendation for a bottom-up multi-actor policy approach for hubs and hub networks in Africa.
DeSSpOt: an instrument for stellar spin orientation determination

description: We designed and constructed a special instrument to enable the determination of the stellar's spin orientation. The Differential image rotator for Stellar Spin Orientation, DeSSpOt, allows the simultaneous observations of two anti-parallel orientations of the star on the spectrum. On a high resolution échelle spectrum, the stellar rotation causes a slight line tilt visible in the spatial direction which is comparable to a rotation curve. We developed a new method, which exploits the variations in these tilts, to estimate the absolute position angle of the rotation axis. The line tilt is retrieved by a spectro-astrometric extraction of the spectrum. In order to validate the method, we observed spectroscopic binaries with known orbital parameters. The determination of the orbital position angle is equivalent to the determination of the stellar position angle, but is easier to to detect. DeSSpOt was successfully implemented on the high resolution Coudé spectrograph of the Thüringer Landessternwarte Tautenburg. The observations of Capella led to the determination of the orbital position angle.

description: In this paper we study Spectral Decomposition Theorem [1] and translate it to quantum language by means of the Wigner transform. We obtain a quantum version of Spectral Decomposition Theorem (QSDT) which enables us to achieve three distinct goals: First, to rank Quantum Ergodic Hierarchy levels [2,3]. Second, to analyze the classical limit in quantum ergodic systems and quantum mixing systems. And third, and maybe most important feature, to find a relevant and simple connection between the first three levels of quantum ergodic hierarchy (ergodic, exact and mixing) and quantum spectrum. Finally, we illustrate the physical relevance of QSDT applying it to two examples: Microwave billiards [4,5] and a phenomenological Gamow model type [6,7].

Sterile neutrino fits to dark matter mass profiles in the Milky Way and in galaxy clusters

description: In several recent papers it was claimed that SN 1987A data supports the existence of 4.0 eV and 21.4 eV active neutrino mass eigenstates, and it was shown that such large masses could be made consistent with existing constraints including neutrino oscillation data and upper limits on the neutrino flavor state masses, provided that there also exist a pair of sterile neutrino mass states whose masses are nearly degenerate with the active ones, plus a third active-sterile doublet that is tachyonic ($m^2 <0$). Here, independent evidence is presented for the existence of sterile neutrinos with the previously claimed masses based on fits to the dark matter distributions in the Milky Way galaxy and four clusters of galaxies. The fits are in excellent agreement with observations. In addition, sterile neutrinos having the suggested masses address the "cusp" problem and the missing satellites problem, as well as that of the "top down" scenario of structure formation -- previously a chief drawback of HDM particles. Nevertheless, the highly controversial nature of the claim, and the need for two free parameters in the dark matter fits, additional confirming evidence will be required before it can be considered proven.

title: EFFECTS OF THINNING REGIMES ON GENETIC VARIATION OF WHITE OAK (QUERCUS ALBA L.) IN UPLAND OAK FORESTS OF EASTERN KENTUCKY
Creators: name: Thunder, Rachel
Publisher: name: University of Kentucky Libraries
Year: 2020

description: This research assesses the effects of silvicultural thinnings, varying in residual basal area and number of thinnings, on genetic diversity and relatedness of white oak (Quercus alba L.). The objectives were to (1) develop microsatellite DNA markers (simple sequence repeats, SSRs) for assessing the genetic diversity of white oak and (2) determine if thinnings significantly change the degree of diversity and relatedness in white oak stands. For objective 1, 84 primer pairs from previously predicted genomic SSRs of white oak were evaluated for consistent PCR amplification and polymorphism. Twenty of the 84 primer pairs amplified consistently and were confirmed to be polymorphic. For objective 2, 16 markers were amplified across 225 white oak trees sampled from seven half-acre plots from a thinning experiment on the Daniel Boone National Forest. Measurements of heterozygosity, total and effective allele numbers, deviation from Hardy-Weinberg equilibrium, and pair-wise genetic relatedness were calculated using GenAlEx 6.5. Analysis suggests that thinning decreases observed heterozygosity relative to expected and relatedness between trees in thinned treatment plots compared to plots that were not thinned. Consideration of genetic effects should be made when thinning white oak stands to maintain genetic diversity while enhancing reproductive success and future stand establishment.

description: In electrovacuum stationary, asymptotically flat black holes in scalar-tensor theories of gravity are described by the Kerr-Newman family of solutions, just as in general relativity. We show that there exist two mechanisms which can render Kerr black holes unstable when matter is present in the vicinity of the black hole, as this induces an effective mass for the scalar. The first mechanism is a tachyonic instability that appears when the effective mass squared is negative, triggering the development of scalar hair --- a black hole version of "spontaneous scalarization". The second instability is associated with superradiance and is present when the effective mass squared is positive and when the black hole spin exceeds a certain threshold. The second mechanism is also responsible for a resonant effect in the superradiant scattering of scalar waves, with amplification factors as large as 10^5 or more.

description: Sustained dialogue and collaborative work between art historians and technologists has a great deal to offer both fields of inquiry. In this paper, we propose that effective collaborations in Digital Art History, however, require more than just a humanist and a technologist to succeed. Indeed, we find that there are four different roles that need to be filled: Humanist, Technologist, Data Steward, and Catalyst. Our approach is predicated on a few foundational convictions. First, we believe that art historians and technologists occupy distinct problem spaces. As we will outline, although these realms are distinct they are not of necessity in opposition to one another. Second, we bring to the fore essential questions about the status and function of data that must be addressed by the collaborators: what sort of data are being used? What counts as effective and compelling analysis of this data? Third, we recognize that there are certain structural impediments to collaboration, such as different reward structures and motivations. Finally, we assert that each of the participants must have a deep commitment to their particular engagement with the project, which requires sustained effort and the maintenance of disciplinary respect. We firmly believe that the most effective of these projects will not be based on technological solutionism, but rather will be founded in the most humanistic of tools: empathy and respect.

description: A spin- and time-dependent electron transport has been studied in a paramagnetic resonant tunneling diode using the self-consistent Wigner-Poisson method. Based on the calculated current-voltage characteristics in an external magnetic field we have demonstrated that under a constant bias both the spin-up and spin-down current components exhibit the THz oscillations in two different bias voltage regimes. We have shown that the oscillations of the spin-up (down) polarized current result from the coupling between the two resonance states: one localized in the triangular quantum well created in the emitter region and the second localized in the main quantum well. We have also elaborated the one-electron model of the current oscillations, which confirms the results obtained with the Wigner-Poisson method. The spin current oscillations can lower the effectiveness of spin filters based on the paramagnetic resonant tunneling structures and can be used to design the generators of the spin polarized current THz oscillations that can operate under the steady bias and constant magnetic field.

CFD Simulation of Heat Enhancement in Internally Helical Grooved Tubes
Creators: name: Pirbastami, Sogol
Publisher: name: University of Nevada, Las Vegas
Year: 2015

description: Heat exchanger devices are widely used in industries, air conditioning systems, refrigeration, etc. These devices have a major role in energy conservation; therefore, increasing the performance of heat exchangers helps save energy, costs and materials. The technique to increase the heat transfer performance is called heat augmentation, which can be applied to pipe surfaces and other surfaces which are used in heat exchangers to improve thermal performance. These techniques are categorized into 3 groups: passive, active and compound technique. In this study a helically machined rectangular groove on the inside of a 2.0 m tube with a diameter of 7.1mm was studied for the heat augmentation effect.
A Computational Fluid Dynamics (CFD) investigation has been carried out to study the heat transfer enhancement in a smooth tube and in four grooved tubes with different pitch sizes (7.1, 12.7, 50 and 130 (mm)). The simulations were performed in the Reynolds number range of 4000-20000. The current CFD predicted values were compared with previously collected experimental data . First, the CFD simulation was run for different groove pitches (203, 254 and 305) to compare them with the published experimental work. The results of these simulations for Nu numbers and friction factors showed good agreement with the experimental values. The primary focus of this study involves evaluating the effect of groove pitch on heat transfer and friction factors. A thermal enhancement factor is defined to evaluate the performance of the internally grooved tubes. By decreasing the pitch size from 130 to 7.1 (mm) at the same Reynolds number, both Nusselt number and friction factor increase. Also, by increasing the Reynolds number, the Nusselt number, as expected, becomes greater. The highest Nusselt number is obtained for smaller pitch size of 7.1 and 12.7 (mm) but at the penalty of a greater pressure drop compared to smooth tubes. It is observed that there is an optimum value of the enhancement factor (?) at about Re = 15,000 for all investigated grooves and enhancement up to 20% is obtained for grooved tubes with 7.1 mm pitch size.
The heat transfer properties of grooved tubes revealed that the CFD simulations can be used to improve future design considerations, which leads to improvement of performance in heat exchanger devices.

description: The uniqueness, value and "fragile" nature of museum exhibits are the main criteria for prohibiting the public from having tactile contact with them, as this could damage them and deprive the experts of valuable knowledge and interpretations. However, a number of our fellow citizens, the Visually Impaired (PWD), use the tactile perception of the morphology of an object as the main means of accessing relevant information, including those regarding the cultural reserve. Modern 3D digitization and printing technologies offer in recent years an alternative method of tangible approach to the cultural stock, through 3D printed copies. In the context of the APTOS project, an attempt was made to strengthen the possibilities of contact of the visually impaired with the cultural reserve, following an interdisciplinary approach with the aim of developing, standardizing and evaluating an innovative methodology, for the tactile exploration of intelligent replicas of exhibits in combination with audio descriptions. This announcement will present the approach followed, the participation of the visually impaired in the various stages of planning, implementation and evaluation of the project, as well as the final pilot systems implemented with exhibits of the Epigraphic Museum and with the tactile map of the permanent exhibition. Finally, a mention will be made to 3D printed smart replicas of cultural objects as a means of enhancing access to culture not only by the visually impaired but also by the general public, during and after the visit to a cultural space.

description: Abstract: EU law incentivises drug marketing authorisation holders (MAHs) to find new uses for their compounds (research known as “repositioning”) by offering them an extra year of market protection if the new use is authorised. This extra year, known as the “+1”, was enacted on limited evidence, and no study has examined its effect since it began. Yet, several leading commentators suggest lengthening the +1. This study assesses the effectiveness of the +1 by analysing all the relevant instances of MAHs repositioning their drugs before and after the +1 came into effect. The results show that: (i) 42.2% of MAHs repositioned their drugs before the +1 came into effect, and (ii) once the +1 did come into effect, it did not increase the percentage of MAHs that repositioned their drugs. This study finds that the +1 failed to increase repositioning and then proceeds to consider reform options, including repealing the law. In doing so, this study takes the first steps towards an evidence-based policy for the topic.

description: The History of Art is in the midst of its own big bang. Amit Sood, the head of the Google Cultural Institute and Art Project, announced such in February 2016 at the Innovation Conference TED in Vancouver. Through its “Arts & Culture” program, Google already offers virtual tours of over one thousand museums and cultural institutions throughout the world, and also provides access to more than six million high-resolution digitized works of art (it should be noted that these figures continue to rise steeply).

description: Research has been devoted in the past few years to relevance feedback as an effective solution to improve performance of information retrieval systems. Relevance feedback refers to an interactive process that helps to improve the retrieval performance. In this paper we propose the use of relevance feedback to improve document image retrieval System (DIRS) performance. This paper compares a variety of strategies for positive and negative feedback. In addition, feature subspace is extracted and updated during the feedback process using a Principal Component Analysis (PCA) technique and based on user's feedback. That is, in addition to reducing the dimensionality of feature spaces, a proper subspace for each type of features is obtained in the feedback process to further improve the retrieval accuracy. Experiments show that using relevance Feedback in DIR achieves better performance than common DIR.

description: We propose a new method to numerically calculate higher-order correlation functions of primordial fluctuations generated from any early-universe scenario. Our key-starting point is the realization that the tree-level In-In formalism is intrinsically separable. This enables us to use modal techniques to efficiently calculate and represent non-Gaussian shapes in a separable form well suited to data analysis. We prove the feasibility and the accuracy of our method by applying it to simple single-field inflationary models in which analytical results are available, and we perform non-trivial consistency checks like the verification of the single field consistency relation. We also point out that the i epsilon prescription is automatically taken into account in our method, preventing the need for ad-hoc tricks to implement it numerically.

description: Transition metal-phtahalocyanine(Pc) compound, TPP[Fe(Pc)(CN)$_2$]$_2$, which is one of molecular conductors of charge transfer type with 3/4-filled conduction band consisting of LUMO of Pc molecules, shows characteristic features in transport and magnetic properties resulting from localized magnetic moments $S=1/2$ associated with Fe$^{+3}$ atoms. We construct an effective tight-binding model of this system and study the mechanism of exchange interaction, $J$, between $d$ and $π$ electrons based on both second order perturbation of transfer integrals between $d$ and $π$ orbitals and numerical diagonalization. It is found that there is no hybridization between $d$-orbitals and LUMO of $π$-orbitals and then super-exchange interaction in the Anderson model does not exist. Instead, processes associated with Hund's rule both on $d$ and $π$ orbitals, which may be called "the double Hund's exchange mechanism", turn out to play important roles and the sign of resultant $J$ can be either ferromagnetic or antiferromagnetic depending on model parameters because of competition among various processes. By taking account of magnetic anisotropy due to spin-orbit interactions and comparing with experimental results, it is indicated that $J$ is antiferromagnetic and of the order of 100K.

description: Abstract: Mitotic catastrophe (MC) is an important oncosuppressive mechanism that serves to eliminate cells that become polyploid or aneuploid due to aberrant mitosis. Previous studies have demonstrated that the activation and catalytic function of caspase-2 are key steps in MC to trigger apoptosis and/or cell cycle arrest of mitotically defective cells. However, the molecular mechanisms that regulate caspase-2 activation and its function are unclear. Here, we identify six new phosphorylation sites in caspase-2 and show that a key mitotic kinase, Aurora B kinase (AURKB), phosphorylates caspase-2 at the highly conserved residue S384. We demonstrate that phosphorylation at S384 blocks caspase-2 catalytic activity and apoptosis function in response to mitotic insults, without affecting caspase-2 dimerisation. Moreover, molecular modelling suggests that phosphorylation at S384 may affect substrate binding by caspase-2. We propose that caspase-2 S384 phosphorylation by AURKB is a key mechanism that controls caspase-2 activation during mitosis.

description: Abstract: Background: By 2050, worldwide dementia prevalence is expected to triple. Affordable, scalable interventions are required to support protective behaviours such as physical activity, cognitive training and healthy eating. This paper outlines the theory-, evidence- and person-based development of ‘Active Brains’: a multi-domain digital behaviour change intervention to reduce cognitive decline amongst older adults. Methods: During the initial planning phase, scoping reviews, consultation with PPI contributors and expert co-investigators and behavioural analysis collated and recorded evidence that was triangulated to inform provisional ‘guiding principles’ and an intervention logic model. The following optimisation phase involved qualitative think aloud and semi-structured interviews with 52 older adults with higher and lower cognitive performance scores. Data were analysed thematically and informed changes and additions to guiding principles, the behavioural analysis and the logic model which, in turn, informed changes to intervention content. Results: Scoping reviews and qualitative interviews suggested that the same intervention content may be suitable for individuals with higher and lower cognitive performance. Qualitative findings revealed that maintaining independence and enjoyment motivated engagement in intervention-targeted behaviours, whereas managing ill health was a potential barrier. Social support for engaging in such activities could provide motivation, but was not desirable for all. These findings informed development of intervention content and functionality that appeared highly acceptable amongst a sample of target users. Conclusions: A digitally delivered intervention with minimal support appears acceptable and potentially engaging to older adults with higher and lower levels of cognitive performance. As well as informing our own intervention development, insights obtained through this process may be useful for others working with, and developing interventions for, older adults and/or those with cognitive impairment.
