description: We present a method to construct new tilting complexes from existing ones using tensor products, generalizing a result of Rickard. The endomorphism rings of these complexes are generalized matrix rings that are "componentwise" tensor products, allowing us to obtain many derived equivalences that have not been observed by using previous techniques. Particular examples include algebras generalizing the ADE-chain related to singularity theory, incidence algebras of posets and certain Auslander algebras or more generally endomorphism algebras of initial preprojective modules over path algebras of quivers. Many of these algebras are fractionally Calabi-Yau and we explicitly compute their CY dimensions. Among the quivers of these algebras one can find shapes of lines, rectangles and triangles.

description: A new approach to the design of massively parallel and interactive programming languages has been recently proposed using rv-systems (interactive systems with registers and voices) and Agapia programming. In this paper we present a few theoretical results on FISs (finite interactive systems), the underlying mechanism used for specifying control and interaction in these systems. First, we give a proof for the undecidability of the emptiness problem for FISs, by reduction to the Post Correspondence Problem. Next, we use the construction in this proof to get other undecidability results, e.g., for the accessibility of a transition in a FIS, or for the finiteness of the language recognized by a FIS. Finally, we present a simple proof of the equivalence between FISs and tile systems, making explicit that they precisely capture recognizable two-dimensional languages.

description: Australia was one of 193 countries that came together at the high-level United Nations (UN) Sustainable Development Summit in New York in September 2015 to commit to achieve the 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals (SDGs). The SDGs are a universal agenda, and their implementation is the shared responsibility of all countries at all stages of development, including OECD nations like Australia. Following a 2018 parliamentary inquiry into Australia’s SDG implementation, the Morrison Government and the Department of Prime Minister and Cabinet (PMAC) will require up-to-date knowledge on international best practice in governance, policy and planning for SDG implementation to inform its response to the 18 recommendations issued by the Australian Senate’s Foreign Affairs and Trade References Committee in February 2019. It is critical that the Australian government takes leadership in the implementation of the SDGs in part because of the political and constitutional peculiarities of Australia’s federal system of government. Only the Commonwealth has the capacity and authority to coordinate the various State and Territory jurisdictions and Local Government bodies. To date implementation of the SDG agenda has lacked leadership, prioritisation and coordination in Australia. Despite submitting its first Voluntary National Report under the SDGs in 2019, the Australian Government is yet to release a national SDG plan of action. The lack of planning and accountability mechanisms and lack of linked financing in the national budget are symptomatic of a deeper problem. In short an apparent lack of political will has meant that the SMART goal logic that many government agencies use for operationalising policy in an array of contexts is simply not present when it comes to the advancement of SDG implementation in Australia.

description: The investigation of multipotent stem/stromal cells (MSCs) in vitro represents an important basis for translational studies in large animal models. The study’s aim was to examine and compare clinically relevant in vitro properties of equine MSCs, which were isolated from abdominal (abd), retrobulbar (rb) and subcutaneous (sc) adipose tissue by collagenase digestion (ASCs-SVF) and an explant technique (ASCs-EXP). Firstly, we examined proliferation and trilineage differentiation and, secondly, the cardiomyogenic differentiation potential using activin A, bone morphogenetic protein-4 and Dickkopf-1. Fibroblast-like, plastic-adherent ASCs-SVF and ASCs-EXP were obtained from all sources. The proliferation and chondrogenic differentiation potential did not differ significantly between the isolation methods and localizations. However, abd-ASCs-EXP showed the highest adipogenic differentiation potential compared to rb- and sc-ASCs-EXP on day 7 and abd-ASCs-SVF a higher adipogenic potential compared to abd-ASCs-EXP on day 14. Osteogenic differentiation potential was comparable at day 14, but by day 21, abd-ASCs-EXP demonstrated a higher osteogenic potential compared to abd-ASCs-SVF and rb-ASCs-EXP. Cardiomyogenic differentiation could not be achieved. This study provides insight into the proliferation and multilineage differentiation potential of equine ASCs and is expected to provide a basis for future preclinical and clinical studies in horses.

description: We determine all the normal subgroups of the group of C^r diffeomorphisms of R^n, r = 1,2,...,infinity, except when r=n+1 or n=4, and also of the group of homeomorphisms of R^n (r=0). We also study the group A_0 of diffeomorphisms of an open manifold M that are isotopic to the identity. If M is the interior of a compact manifold with nonempty boundary, then the quotient of A_0 by the normal subgroup of diffeomorphisms that coincide with the identity near to a given end e of M is simple.

description: We propose a new method to derive certain higher order estimates in quantum electrodynamics. Our method is particularly convenient in the application to the non-local semi-relativistic models of quantum electrodynamics as it avoids the use of iterated commutator expansions. We re-derive higher order estimates obtained earlier by Fröhlich, Griesemer, and Schlein and prove new estimates for a non-local molecular no-pair operator.

description: Without prior knowledge, distinguishing different languages may be a hard task, especially when their borders are permeable. We develop an extension of spectral clustering -- a powerful unsupervised classification toolbox -- that is shown to resolve accurately the task of soft language distinction. At the heart of our approach, we replace the usual hard membership assignment of spectral clustering by a soft, probabilistic assignment, which also presents the advantage to bypass a well-known complexity bottleneck of the method. Furthermore, our approach relies on a novel, convenient construction of a Markov chain out of a corpus. Extensive experiments with a readily available system clearly display the potential of the method, which brings a visually appealing soft distinction of languages that may define altogether a whole corpus.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We construct new M-theory solutions starting from those that contain 5 U(1) isometries. We do this by reducing along one of the 5-torus directions, then T-dualizing via the action of an O(4,4) matrix and lifting back to 11-dimensions. The particular T-duality transformation is a sequence of O(2,2) transformations embedded in O(4,4), where the action of each O(2,2) gives a Lunin-Maldacena deformation in 10-dimensions. We find general formulas for the metric and 4-form field of single and multiparameter deformed solutions, when the 4-form of the initial 11-dimensional background has at most one leg along the 5-torus. All the deformation terms in the new solutions are given in terms of subdeterminants of a 5x5 matrix, which represents the metric on the 5-torus. We apply these results to several M-theory backgrounds of the type AdS_r x X^{11-r}. By appropriate choices of the T-duality and reduction directions we obtain analogues of beta, dipole and noncommutative deformations. We also provide formulas for backgrounds with only 3 or 4 U(1) isometries and study a case, for which our assumption for the 4-form field is violated.

description: Temporal coherence is a fundamental property of macroscopic quantum systems, such as lasers in optics and Bose-Einstein condensates in atomic gases and it is a crucial issue for interferometry applications with light or matter waves. Whereas the laser is an "open" quantum system, ultracold atomic gases are weakly coupled to the environment and may be considered as isolated. The coherence time of a condensate is then intrinsic to the system and its derivation is out of the frame of laser theory. Using quantum kinetic theory, we predict that the interaction with non-condensed modes gradually smears out the condensate phase, with a variance growing as A t^2+B t+C at long times t, and we give a quantitative prediction for A, B and C. Whereas the coefficient A vanishes for vanishing energy fluctuations in the initial state, the coefficients B and C are remarkably insensitive to these fluctuations. The coefficient B describes a diffusive motion of the condensate phase that sets the ultimate limit to the condensate coherence time. We briefly discuss the possibility to observe the predicted phase spreading, also including the effect of particle losses.

description: Citizen energy in general and renewable energy communities (RECs) in particular are becoming key vehicles for decentralisation, but also for the democratisation of the energy system. These initiatives are now more diverse than ever and are likely to continue to act as incubators for significant projects in the transition to a renewable energy system. Beside the legal, regulatory, and financial challenges, there are several socio-economic and regulatory barriers that hinder the implementation of community energy projects. For this reason, policy learning and the dissemination of good/best practices that are transferable also to other contexts are important. This is an aspect that has not yet attracted much investigation, and only a few studies have explored the importance of transfer activities for the implementation of REC initiatives and their motives. This article aimed to address this knowledge gap by focussing on the transfer processes of best practices initiated in a particular region and discusses how these can be adapted and transferred to other contexts. We analysed the transfer case of a community renewable energy initiative, the multifunctional energy gardens, from the Netherlands to the German federal State of Thuringia, and extracted lessons with an overall validity for the transferability of drivers and success factors. We show how examples from other contexts with similar enabling conditions can represent significant foundations on which to build an effective strategy and what framework conditions are necessary to enhance the uptake of pervasive community energy initiatives in regions with low community energy development.
Relationships between seasonal biochemical changes and the reproductive cycle of the intertidal gastropod Thais lamellosa Gmelin (Gastropoda, Prosobranchia).
Creators: name: Lambert, Philip
Publisher: name: University of British Columbia
Year: 2011

description: The seasonal variation in the major biochemical constituents of T. lamellosa Gmelin have been studied in relation to the reproductive cycle. Digestive gland, foot muscle and gonad were analysed for protein, glycogen, lipid and ash over a period of one year. In addition to biochemical analyses, histological sections of digestive gland and gonad were made throughout the same period. Histological data supplied information on feeding and gamete maturation. Two major periods of feeding activity occurred in April and August. Gametogenesis began in late summer and the peak spawning period was in March. Glycogen is at a maximum in the digestive gland at times of maximum feeding, but food is stored in the digestive gland in the form of lipid. Stored lipid is utilized by the animal during the winter. Glycogen is at a low level in all tissues and appears to be used primarily for lipid and yolk synthesis. The foot muscle does not store either lipid or glycogen to any appreciable extent. Under normal field conditions during the winter, the digestive gland index decreases as reserves are utilized, while the gonad size is maintained until spawning. Animals which are maintained through the same period under artificial summer conditions, show no loss in the digestive gland index, but a decrease in the size of the gonad. None of the oogonia reach maturity and the mature oocytes are resorbed. The starved animals resorb more material from the gonad than fed animals. The possible role of environmental factors in controlling reproduction is discussed.

description: Bias-tailoring allows quantum error correction codes to exploit qubit noise asymmetry. Recently, it was shown that a modified form of the surface code, the XZZX code, exhibits considerably improved performance under biased noise. In this work, we demonstrate that quantum low density parity check codes can be similarly bias-tailored. We introduce a bias-tailored lifted product code construction that provides the framework to expand bias-tailoring methods beyond the family of 2D topological codes. We present examples of bias-tailored lifted product codes based on classical quasi-cyclic codes and numerically assess their performance using a belief propagation plus ordered statistics decoder. Our Monte Carlo simulations, performed under asymmetric noise, show that bias-tailored codes achieve several orders of magnitude improvement in their error suppression relative to depolarising noise.

description: We report the results of a spectroscopic and polarimetric study of the massive, hydrogen-rich WN6h stars R144 (HD 38282 = BAT99-118 = Brey 89) and R145 (HDE 269928 = BAT99-119 = Brey 90) in the LMC. Both stars have been suspected to be binaries by previous studies (R144: Schnurr et al. 2008b; R145: Moffat 1989). We have combined radial-velocity (RV) data from these two studies with previously unpublished polarimetric data. For R145, we were able to establish, for the first time, an orbital period of 158.8 days, along with the full set of orbital parameters, including the inclination angle i, which was found to be i = 38 \pm 9 deg. By applying a modified version of the shift-and-add method developed by Demers et al. (2002), we were able to isolate the spectral signature of the very faint-line companion star. With the RV amplitudes of both components in R145, we were thus able to estimate their absolute masses. We find minimum masses M_WR sin^{3}i = (116 \pm 33) M_sol and M_O sin^{3}i = (48 \pm 20)$ M_sol for the WR and the O component, respectively. Thus, if the low inclination angle were correct, resulting absolute masses of the components would be at least 300 and 125 M_sol, respectively. However, such high masses are not supported by brightness considerations when R145 is compared to systems with known, very high masses such as NGC3603-A1 or WR20a. An inclination angle close to 90 degrees would remedy the situation, but is excluded by the currently available data. More and better data are thus required to firmly establish the nature of this puzzling, yet potentially very massive and important system. As to R144, however, the combined data sets are not sufficient to find any periodicity.

Subjects: subject: Probability (math.PR)

description: Let X be a spectrally negative self-similar Markov process with 0 as an absorbing state. In this paper, we show that the distribution of the absorption time is absolutely continuous with an infinitely continuously differentiable density. We provide a power series and a contour integral representation of this density. Then, by means of probabilistic arguments, we deduce some interesting analytical properties satisfied by these functions, which include, for instance, several types of hypergeometric functions. We also give several characterizations of the Kesten's constant appearing in the study of the asymptotic tail distribution of the absorbtion time. We end the paper by detailing some known and new examples. In particular, we offer an alternative proof of the recent result obtained by Bernyk, Dalang and Peskir [Ann. Probab. 36 (2008) 1777--1789] regarding the law of the maximum of spectrally positive Lévy stable processes.

Effects of various physical and chemical treatments on the in virtro rumen digestibility and chemical composition of four woods.
Creators: name: Huffman, James Grant
Publisher: name: University of British Columbia
Year: 2011

description: Samples of sawdust from poplar, alder and Douglas fir, were ground past screens ranging in size from 2.21 mm to 0.25 mm (60 mesh). A reduction in particle size significantly increased the in vitro rumen digestibility of poplar, but had little effect on the digestibility of alder or fir. The above woods, plus sludge (a by-product of the pulping process) were treated with NaOH solutions of 2, 4 and 6%. These solutions were used at three treatment periods of 0.5, 1.0 and 1.5 hours, and all treatments were carried out at 1.05 kg/sq cm and 121° C. NaOH treatment significantly increased the in vitro cellulose digestibility of all woods except fir. The optimum treatment conditions for increasing the in vitro cellulose digestibility of all woods were 4% NaOH at the 1.5 hour treatment period, except in the case of alder which was most digestible when treated with 2% NaOH for 1.5 hours. Gamma irradiation increased the in vitro cellulose digestibility of all woods. Alder and fir were most digestible when treated with 2 x 10⁸ rads, but poplar and sludge reached their peak digestibility when exposed to 1 x 10⁸ rads. Irradiation was found to decrease the cellulose and acid detergent fibre (ADF) content of all the woods studied. Acid detergent lignin (ADL) also decreased in response to irradiation in all woods except sludge. Irradiation had no effect on the ash content of any of the samples. Three methods of cellulose analysis were used on both untreated and irradiated wood, and there was a significant difference shown among the methods. The lowest values were obtained using Van Soests' KMnO₄ method, next were the results from Van Soests' 72% Hg₂SO₄ method, and the highest values were obtained using the Crampton and Maynard procedure for cellulose. Two lignin methods were also compared and it was found that the KMnO₄ lignin values were significantly higher than those obtained using the 72% H₂S0₄ method for lignin.

description: An 8-year-old male Rhodesian Ridgeback was presented with fever and severe thrombocytopenia. Clinical and laboratory examination, echocardiography, blood culture, and pathohistology revealed evidence of infective endocarditis, ischemic renal infarcts, and septic encephalitis. Treatment was started immediately but the dog’s condition worsened, and the dog had to be euthanized. The causative Streptococcus canis strain was detected by blood culture and MALDI-TOF MS and analyzed using whole-genome sequencing and multilocus sequence typing. Antibiotic susceptibility testing did not detect any resistance. The affected heart valve was analyzed using FISH imaging, which showed a streptococcal biofilm on the heart valve. Bacteria in biofilms are recalcitrant to antibiotic treatment. Early diagnosis could be beneficial to treatment outcome. Treatment of endocarditis could be improved by researching the optimal dosage of antibiotics in conjunction with the use of biofilm-active drugs.

description: Background: Beyond prostate-specific antigen (PSA), other biomarkers for prostate cancer (PCa) detection are available and need to be evaluated for clinical routine. Objective: The aim of the study was to evaluate the Prostate Health Index (PHI) density (PHID) in comparison with PHI in a large Caucasian group >1,000 men. Methods: PHID values were used from available patient data with PSA, free PSA, and [-2]pro-PSA and prostate volume from 3 former surveys from 2002 to 2014. Those 1,446 patients from a single-center cohort included 701 men with PCa and 745 with no PCa. All patients received initial or repeat biopsies. The diagnostic accuracy was evaluated by receiver operating characteristic (ROC) curves comparing area under the ROC curves (AUCs), precision-recall approach, and decision curve analysis (DCA). Results: PHID medians differed almost 2-fold between PCa (1.12) and no PCa (0.62) in comparison to PHI (48.6 vs. 33; p always <0.0001). However, PHID and PHI were equal regarding the AUC (0.737 vs. 0.749; p = 0.226), and the curves of the precision-recall analysis also overlapped in the sensitivity range between 70 and 100%. DCA had a maximum net benefit of only similar to 5% for PHID versus PHI between 45 and 55% threshold probability. Contrary, in the 689 men with a prostate volume <= 40 cm(3), PHI (AUC 0.732) showed a significant larger AUC than PHID (AUC 0.69, p = 0.014). Conclusions: Based on DCA, PHID had only a small advantage in comparison with PHI alone, while ROC analysis and precision-recall analysis showed similar results. In smaller prostates, PHI even outperformed PHID. The increment for PHID in this large Caucasian cohort is too small to justify a routine clinical use.
A systematic review of the factors impacting job satisfaction of new nurse graduates engaging in a hospital-based nurse residency program
Creators: name: Majekodunmi, Taiwo
Publisher: name: No Publisher Supplied

description: Purpose of the Project: This systematic review examined whether job satisfaction is enhanced among new nurse graduates participating in NRPs during their first two years of employment. It aimed to assess how job satisfaction is influenced by NRPs, along with the impact on retention rates and the perceived skill levels of NGNs within the first 12 months in acute care settings. Methods: This review used a three-step systematic approach based on the Joanna Briggs Institute (JBI) to retrieve quantitative studies examining participants in NGNs contributing to NRPs. Using JBI critical appraisal tools, articles were appraised, and a narrative synthesis was used.Results: Initially, 150 records were identified including 110 from Medline and 40 from CINAHL. After removing duplicates and ineligible records (n = 65), 105 records were screened, 31 records were excluded based on relevance. The remaining 74 reports were assessed for eligibility. Ultimately, 64 reports were excluded based on further criteria, leaving 10 studies included in the final review. The overall retention rate was 91%, indicating that NRPs could contribute to increased job satisfaction. NRPs significantly improved job satisfaction, contributing to a 91% retention rate for NGNs. While enhancing job satisfaction, NRPs also aimed to boost the perceived competence of NGNs. Implications: NRPs provide a valuable tactic for helping NGNs improve job satisfaction and retention and thus reduce turnover costs for healthcare organizations. Future research should focus on identifying the specific components of NRPs that lead to higher job satisfaction and consider developing universal competency measures to standardize outcomes.Keywords: nurse residency programs, new graduate nurses, retention, competency, systematic review, job satisfaction

description: We classify all negatively curved $\R^n \rtimes \R$ up to quasiisometry. We show that all quasiisometries between such manifolds (except when they are biLipschitz to the real hyperbolic spaces) are almost similarities. We prove these results by studying the quasisymmetric maps on the ideal boundary of these manifolds.

The application of landscape productivity and environmental modelling to improve plantation site selection and yield prediction
Creators: name: Mummery, DC
Publisher: name: University Of Tasmania
Year: 2023

description: The area planted to Eucalyptus globulus (Labill.) in southern Australia has increased rapidly. However, robust site selection and productivity prediction models have only become available recently for this species. The silvicultural and management questions being explored with these models cover a range of temporal and spatial scales. The models themselves are complex, data intensive and highly non-linear in their function. This raises a number of important issues that affect model application. These issues are explored with a series of applied examples. Firstly, what is the effect of patchy input data of limited extent? Models designed using sampling plot data on which soils data are recorded are now applied across broad landscape extents to make site selection decisions and regional productivity estimates. The work in this thesis shows in separate examples how terrain analysis can be used to supplement input surfaces, including surfaces related to waterlogging and soil nutrition. An approach is developed for dealing with poorly defined soils variables such as soil depth and used to categorise regional forest productivity based not only on the expected yield but the co-efficient of variation in that yield. In a further example this approach is used to define appropriate site surveying procedures for plantation land assessment. In addition to examining the effect of model predictive accuracy on the quality of spatial inputs, input data grain size is examined to identify the scale sensitivity of the model. This is important because the same forest growth models are used to predict the yield of individual forest plots and to make continental scale predictions. The results indicate that forest productivity models like PROMOD are not scale dependent and even with the use of broad-scale input data provide unbiased estimates of mean productivity. However, a comparison using fine-scale data (10 x 10 metre) shows that sub-grid variance at large scales (1000 x 1000 metre) can be very large, particularly for soil variables that can change abruptly over short distances. Just as spatial input variables vary in quality and scale so may the temporal (particularly weather) variables supplied to models. Using rainfall representation in models as an example, an analysis of the intrinsic input data variability allows a more sophisticated consideration of site selection that includes risk evaluation as a criteria. Furthermore, it was shown that incorporating the distributional characteristics of rainfall markedly affects the prediction of the risk associated with a particular plantation development.

description: Recent work in gravitational lensing and catastrophe theory has shown that the sum of the signed magnifications of images near folds, cusps and also higher catastrophes is zero. Here, it is discussed how Lefschetz fixed point theory can be used to interpret this result geometrically. It is shown for the generic case as well as for elliptic and hyperbolic umbilics in gravitational lensing.

description: We study the free energy of the directed polymer in random environment in dimension 1+1 and 1+2. For dimension 1, we improve the statement of Comets and Vargas concerning very strong disorder by giving sharp estimates on the free energy at high temperature. In dimension 2, we prove that very strong disorder holds at all temperatures, thus solving a long standing conjecture in the field.

Minimally Allowed Neutrinoless Double Beta Decay Rates From Approximate Flavor Symmetries

Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Neutrinoless double beta decay ($β\beta0ν$) is among the only realistic probes of Majorana neutrinos. In the standard scenario, dominated by light neutrino exchange, the process amplitude is proportional to $m_{ee}$, the $e-e$ element of the Majorana mass matrix. Naively, current data allows for vanishing $m_{ee}$, but this should be protected by an appropriate flavor symmetry. All such symmetries lead to mass matrices inconsistent with oscillation phenomenology. I perform a spurion analysis to break all possible Abelian symmetries that guarantee vanishing $β\beta0ν$ rates and search for minimally allowed values. I survey 230 broken structures to yield $m_{ee}$ values and current phenomenological constraints under a variety of scenarios. This analysis also extracts predictions for both neutrino oscillation parameters and kinematic quantities. Assuming reasonable tuning levels, I find that $m_{ee}>4\times 10^{-6}$ eV at 99% confidence. Bounds below this value might indicate the Dirac neutrino nature or the existence of new light (eV-MeV scale) degrees of freedom that can potentially be probed elsewhere.

description: Glycosylation is a highly complex process to produce a diverse repertoire of cellular glycans that are attached to proteins and lipids. Glycans are involved in fundamental biological processes, including protein folding and clearance, cell proliferation and apoptosis, development, immune responses, and pathogenesis. One of the major types of glycans, N-linked glycans, is formed by sequential attachments of monosaccharides to proteins by a limited number of enzymes. Many of these enzymes can accept multiple N-linked glycans as substrates, thereby generating a large number of glycan intermediates and their intermingled pathways. Motivated by the quantitative methods developed in complex network research, we investigated the large-scale organization of such N-linked glycosylation pathways in mammalian cells. The N-linked glycosylation pathways are extremely modular, and are composed of cohesive topological modules that directly branch from a common upstream pathway of glycan synthesis. This unique structural property allows the glycan production between modules to be controlled by the upstream region. Although the enzymes act on multiple glycan substrates, indicating cross-talk between modules, the impact of the cross-talk on the module-specific enhancement of glycan synthesis may be confined within a moderate range by transcription-level control. The findings of the present study provide experimentally-testable predictions for glycosylation processes, and may be applicable to therapeutic glycoprotein engineering.
