description: We present observations of interstellar rubidium toward o Per, zeta Per, AE Aur, HD 147889, chi Oph, zeta Oph, and 20 Aql. Theory suggests that stable 85Rb and long-lived 87Rb are produced predominantly by high-mass stars, through a combination of the weak s- and r-processes. The 85Rb/87Rb ratio was determined from measurements of the Rb I line at 7800 angstroms and was compared to the solar system meteoritic ratio of 2.59. Within 1-sigma uncertainties all directions except HD 147889 have Rb isotope ratios consistent with the solar system value. The ratio toward HD 147889 is much lower than the meteoritic value and similar to that toward rho Oph A (Federman et al. 2004); both lines of sight probe the Rho Ophiuchus Molecular Cloud. The earlier result was attributed to a deficit of r-processed 85Rb. Our larger sample suggests instead that 87Rb is enhanced in these two lines of sight. When the total elemental abundance of Rb is compared to the K elemental abundance, the interstellar Rb/K ratio is significantly lower than the meteoritic ratio for all the sight lines in this study. Available interstellar samples for other s- and r- process elements are used to help interpret these results.

description: Using large-scale quantum Monte Carlo simulations, we determine the ground state phase diagram of the spin-1/2 antiferromagnetic Heisenberg model on the honeycomb lattice for the most generic case of three varying interaction strengths along the different lattice directions. We identify continuous quantum phase transition lines that separate the long-range ordered antiferromagnetic regime from three distinct quantum-disordered phases, each characterized by dominant dimer-singlet formations. The finite-size behavior along these phase transition lines exhibits anomalously large corrections to scaling, which we relate to similar recent findings in certain dimerized quantum spin systems and to singular one-dimensional limits in the model parameter space. We also comment more generally on the non-universality of critical cumulant ratios in anisotropic systems and attempts to restore universality by varying the aspect ratio.

description: Loblolly pine (P. taeda) is the most important commercial tree species in the southern United States because of its good growth characteristics, desirable wood properties, and broad range . And in China, P. taeda is a major non-native plantation species especially in south China. The use of a breeding strategy has been used in the breeding program of loblolly pine in China since 1980s. Since the cp genome is paternally inherited, it may help to identify the paternity of the selected tree if the maternity is already known. Because of its simple structure, highly conserved sequence, and single parental (maternal or paternal) inheritance characters, the study of the cp genome has become a universal method for evolutionary, taxonomy, and phylogenetic analyses of plants In all conifers. And the cp genome of P. taeda may not be as conserved as previously believed,for nine mutational loci were detected in ycf1 of P. taeda. In recent years, research on chloroplasts has become increasingly in-depth; however, studies focusing on the chloroplast genome of Loblolly pine remain insufficiently comprehensive. Consequently, we utilized Loblolly pine needles to sequence its chloroplast genome, aiming for a more detailed understanding of the chloroplast gene sequences, genomic structure, and SNP variations. This work is intended to provide relevant gene site information for individual identification in Loblolly pine breeding.

description: Weak boson scattering processes provide particularly promising means for gaining insight into the mechanism of electroweak symmetry breaking at hadron colliders. Being very sensitive to interactions in the weak gauge boson sector, they will help to distinguish the Standard Model from various new physics scenarios such as extra-dimensional Higgsless models. To unambiguously identify signatures of new physics, precise predictions for experimentally accessible observables within realistic selection cuts are crucial, including next-to-leading order QCD corrections. Here, we review how flexible Monte-Carlo methods can be employed for precision analyses of weak boson scattering reactions within the Standard Model and beyond.

description: Learning personalization has proven its effectiveness in enhancing learner performance. Therefore, modern digital learning platforms have been increasingly depending on recommendation systems to offer learners personalized suggestions of learning materials. Learners can utilize those recommendations to acquire certain skills for the labor market or for their formal education. Personalization can be based on several factors, such as personal preference, social connections or learning context. In an educational environment, the learning context plays an important role in generating sound recommendations, which not only fulfill the preferences of the learner, but also correspond to the pedagogical goals of the learning process. This is because a learning context describes the actual situation of the learner at the moment of requesting a learning recommendation. It provides information about the learner current state of knowledge, goal orientation, motivation, needs, available time, and other factors that reflect their status and may influence how learning recommendations are perceived and utilized. Context aware recommender systems have the potential to reflect the logic that a learning expert may follow in recommending materials to students with respect to their status and needs. In this paper, we review the state-of-the-art approaches for defining a user learning-context. We provide an overview of the definitions available, as well as the different factors that are considered when defining a context. Moreover, we further investigate the links between those factors and their pedagogical foundations in learning theories. We aim to provide a comprehensive understanding of contextualized learning from both pedagogical and technical points of view. By combining those two viewpoints, we aim to bridge a gap between both domains, in terms of contextualizing learning recommendations.

'It was almost normal' : the significance of kid's days at Tasmania's Risdon Prison in maintaining connections between children and their incarcerated parents
Creators: name: Toohey, J-A
Publisher: name: University Of Tasmania
Year: 2023

description: It is unfortunate that in an era when progressive thinking is celebrated, human rights are on many people's agenda, and both government and non-government organisations are supposedly working to create a more sustainable life for those considered to be marginalised, the difficulties that families of prisoners face rarely take centre stage in political forums or policy debates. Imprisonment, essentially based on a model of retribution, is immune to the plight of families, caught up in the 'ripple effect' that extends well beyond the incarcerated family member. The following research examines the challenges encountered by the children of prisoners and considers the emotional, social and financial toll that arises as a result of parental incarceration as well as the potential risks of intergenerational criminality. Despite calls from lobby groups, no-one regularly monitors the parental status of prisoners - the collection of statistics is generally dependent upon researchers and non-government organisations. This study investigates Kids' Days at Tasmania's Risdon Prison. These special days are designed to improve contact and interaction between children and their imprisoned parents. Kids' Days recognise the rights of children to know and interact with their parents, and for parents, regardless of their status as prisoners, to know and interact with their children.

description: Recent work by Zymnis et al. proposes an efficient primal-dual interior-point method, using a truncated Newton method, for solving the network utility maximization (NUM) problem. This method has shown superior performance relative to the traditional dual-decomposition approach. Other recent work by Bickson et al. shows how to compute efficiently and distributively the Newton step, which is the main computational bottleneck of the Newton method, utilizing the Gaussian belief propagation algorithm. In the current work, we combine both approaches to create an efficient distributed algorithm for solving the NUM problem. Unlike the work of Zymnis, which uses a centralized approach, our new algorithm is easily distributed. Using an empirical evaluation we show that our new method outperforms previous approaches, including the truncated Newton method and dual-decomposition methods. As an additional contribution, this is the first work that evaluates the performance of the Gaussian belief propagation algorithm vs. the preconditioned conjugate gradient method, for a large scale problem.

description: Consider the $n!$ different unitary matrices that permute $n$ $d$-dimensional quantum systems. If $d\geq n$ then they are linearly independent. This paper discusses a sense in which they are approximately orthogonal (with respect to the Hilbert-Schmidt inner product) if $d\gg n^2$, or, in a different sense, if $d\gg n$. Previous work had shown pairwise approximate orthogonality of these matrices, but here we show a more collective statement, quantified in terms of the operator norm distance of the Gram matrix to the identity matrix.
 This simple point has several applications in quantum information and random matrix theory: (1) showing that random maximally entangled states resemble fully random states, (2) showing that Boson sampling output probabilities resemble those from Gaussian matrices, (3) improving the Eggeling-Werner scheme for multipartite data hiding, (4) proving that the product test of Harrow-Montanaro cannot be performed using LOCC without a large number of copies of the state to be tested, (5) proving that the purity of a quantum state also cannot be efficiently tested using LOCC, and (6, published separately) helping prove that poly-size random quantum circuits are poly-designs.

Laboratory study on aerated stabilization basin operation at 3°C
Creators: name: Atwater, James Wesley
Publisher: name: University of British Columbia
Year: 2011

description: Aerated stabilization basins (ASB), like many other biological treatment systems, demonstrate a temperature dependency. A decrease in treatment efficiency usually results from a decreasing basin temperature and has often been related to a decrease in the reaction rate coefficient, K. This relationship to the reaction rate may well apply for other treatment systems, but it has not been clearly demonstrated for aerated stabilization basins. This study develops data on steady-state performance at 3° C in order to present a coherent reference point for future ASB temperature studies and to define performance characteristics at 3°C. The following performance criteria were documented in the study: 1. Substrate removal in terms of filtered substrate removal. (61 - 80 per cent COD removal and 76 -98 per cent BOD₅ removal for retention times of 1 - 16 days). 2. System treatment efficiency defined in terms of gross effluent COD and BOD₅. (23 - 50 per cent COD removal and 18 - 80 per cent BOD₅ removal for retention times of 1 - 16 days). 3. Net biological solids production (0.25 lbs/lb BODu or COD used). 4. Oxygen utilization requirements (0.123 lbs O₂/ lb COD removed and 0.143 lbs O₂/BOD₅ removed for retention times of 2 - 16 days. Endogenous respiration - 0.75 mg/hr/ gm MLSS). 5. Nitrogen transformation. (A transformation of Kjeldahl nitrogen in the biological solids to NH₃ nitrogen in the filtrate was found apparently as a function of retention time). 6. Post Settling. (One day's aeration with one day settling was found to give equivalent treatment as eight days aeration and one day settling). Data was obtained at two loadings to provide information on the influence of influent concentration on overall performance. Established in the experiment was that any of the common mathematical models used to describe ASB operation, McKinney's, Eckenfelder's, or first-order exponential, could predict system treatment efficiency at 3°C for retention times beyond two to four days. It was further shown that only the Chemostat model would describe the substrate removal measured in the study.

description: Photographs taken with less-than-ideal exposure settings often display poor visual quality. Since the correction procedures vary significantly, it is difficult for a single neural network to handle all exposure problems. Moreover, the inherent limitations of convolutions, hinder the models ability to restore faithful color or details on extremely over-/under- exposed regions. To overcome these limitations, we propose a Macro-Micro-Hierarchical transformer, which consists of a macro attention to capture long-range dependencies, a micro attention to extract local features, and a hierarchical structure for coarse-to-fine correction. In specific, the complementary macro-micro attention designs enhance locality while allowing global interactions. The hierarchical structure enables the network to correct exposure errors of different scales layer by layer. Furthermore, we propose a contrast constraint and couple it seamlessly in the loss function, where the corrected image is pulled towards the positive sample and pushed away from the dynamically generated negative samples. Thus the remaining color distortion and loss of detail can be removed. We also extend our method as an image enhancer for low-light face recognition and low-light semantic segmentation. Experiments demonstrate that our approach obtains more attractive results than state-of-the-art methods quantitatively and qualitatively.

Exponential error rates in multiple state discrimination on a quantum spin chain

Year: 2010
Subjects: subject: Quantum Physics (quant-ph)

description: We consider decision problems on finite sets of hypotheses represented by pairwise different shift-invariant states on a quantum spin chain. The decision in favor of one of the hypotheses is based on outputs of generalized measurements performed on local states on blocks of finite size. We assume existence of the mean quantum Chernoff distances of any pair of states from the given set and refer to the minimum of them as the mean generalized quantum Chernoff distance. We establish that this minimum specifies an asymptotic bound on the exponential decay of the averaged probability of rejecting the true state in increasing block size, if the mean quantum Chernoff distance of any pair of the hypothetic states is achievable as an asymptotic error exponent in the corresponding binary problem. This assumption is in particular fulfiled by shift-invariant product states (i.i.d. states). Further, we provide a constructive proof for the existence of a sequence of quantum tests in increasing block size, which achieves an asymptotic error exponent which is equal to the mean generalized quantum Chernoff distance of the given set of states up to a factor, which depends on the set itself. It can be arbitrary close to 1 and is not less than $1/m$ for $m$ being the number of different pairs of states from the set considered.

description: Theory is developed for linear-quadratic at infinity generating families for Legendrian knots in R^3. It is shown that the unknot with maximal Thurston--Bennequin invariant of -1 has a unique linear-quadratic at infinity generating family, up to fiber-preserving diffeomorphism and stabilization. From this, invariant generating family polynomials are constructed for 2-component Legendrian links where each component is a maximal unknot. Techniques are developed to compute these polynomials, and computations are done for two families of Legendrian links: rational links and twist links. The polynomials allow one to show that some topologically equivalent links with the same classical invariants are not Legendrian equivalent. It is also shown that for these families of links the generating family polynomials agree with the polynomials arising from a linearization of the differential graded algebra associated to the links.

description: This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.

description: In recent years, new algorithms and cryptographic protocols based on the laws of quantum physics have been designed to outperform classical communication and computation. We show that the quantum world also opens up new perspectives in the field of complex networks. Already the simplest model of a classical random network changes dramatically when extended to the quantum case, as we obtain a completely distinct behavior of the critical probabilities at which different subgraphs appear. In particular, in a network of N nodes, any quantum subgraph can be generated by local operations and classical communication if the entanglement between pairs of nodes scales as 1/N^2.

Very Fast X-Ray Variabiity in BL Lac Objects: The Athena Prospect

description: BL Lacs for represent an extreme blazar subclass of with a relativistic jet closely aligned with our line-of-sight and characterized by non-thermal continuum emission across the entire spectrum, superluminal motion, almost featureless optical spectra and strong flux variability in all spectral bands. The latter property is crucial in discerning the innermost structure of these sources which is overwhelmed by the strong, relativistic boosted jet emission. While the fastest, subhour variability in the flaring states is widely explained in the framework of the shock-in-jet scenario (the variability triggered by the interaction of the relativistic shock front and jet turbulent inhomogeneities), those observed in lower states can be related to the instabilities in the innermost area of the accretion disc. The latter are of the particular importance: asides providing important information about the triggering instable processes, these instances also allow us to evaluate masses of the central supermassive black holes (SMBHs). In lower X-ray states of BL Lacs, such variability is more evident and easier to detect since it is not overwhelmed by the tremendous nonthermal jet emission generated near the front of the propagating shock. However, the instrumental capabilities of the current space X-ray missions are still not sufficient to reveal the subhour flux variability in lower states owing to the faintness of BL Lacs in those periods. Moreover, the planned X-ray Integral Field Unit at Athena is very important in recording high signal-to-noise 0.2-12 keV spectra within the short time intervals and study very fast spectral variability, which provides us with another powerful tool for the further progress in our understanding of the instable processes in the SMBH vicinity.
Non-Abelian k-Vortex Dynamics in N=1^* theory and its Gravity Dual

description: We study magnetic flux tubes in the Higgs vacuum of the N=1^* mass deformation of SU(N_c), N=4 SYM and its large N_c string dual, the Polchinski-Strassler geometry. Choosing equal masses for the three adjoint chiral multiplets, for all N_c we identify a "colour-flavour locked" symmetry, SO(3)_{C+F} which leaves the Higgs vacuum invariant. At weak coupling, we find explicit non-Abelian k-vortex solutions carrying a Z_{N_c}-valued magnetic flux, with winding, 0 < k < N_c. These k-strings spontaneously break SO(3)_{C+F} to U(1)_{C+F} resulting in an S^2 moduli space of solutions. The world-sheet sigma model is a nonsupersymmetric CP^1 model with a theta angle θ_{1+1} = k(N_c-k)θ_{3+1} where θ_{3+1} is the Yang-Mills vacuum angle. We find numerically that k-vortex tensions follow the Casimir scaling law T_k \propto k (N_c-k) for large N_c. In the large N_c IIB string dual, the SO(3)_{C+F} symmetry is manifest in the geometry interpolating between AdS_5 x S^5 and the interior metric due to a single D5-brane carrying D3-brane charge. We identify candidate k-vortices as expanded probe D3-branes formed from a collection of k D-strings. The resulting k-vortex tension exhibits precise Casimir scaling, and the effective world-sheet theta angle matches the semiclassical result. S-duality maps the Higgs to the confining phase so that confining string tensions at strong 't Hooft coupling also exhibit Casimir scaling in N=1^* theory in the large N_c limit.

description: The Giessen Boltzmann-Uehling-Uhlenbeck transport model is extended and applied to the antiproton-nucleus interactions in a wide beam momentum range. The model calculations are compared with the experimental data on $\bar p$-absorption cross sections on nuclei with an emphasis on extraction of the real part of an antiproton optical potential. The possibility of the cold compression of a nucleus by an antiproton in-flight is also considered.
