description: Atom probe tomography (APT) is ideally suited to characterize and understand the interplay of chemical segregation and microstructure in modern multicomponent materials. Yet, the quantitative analysis typically relies on human expertise to define regions of interest. We introduce a computationally efficient, multistage machine learning strategy to identify chemically distinct domains in a semi automated way, and subsequently quantify their geometric and compositional characteristics. In our algorithmic pipeline, we first coarse grain the APT data into voxels, collect the composition statistics, and decompose it via clustering in composition space. The composition classification then enables the real space segmentation via a density based clustering algorithm, thus revealing the microstructure at voxel resolution. Our approach is demonstrated for a Sm(Co,Fe)ZrCu alloy. The alloy exhibits two precipitate phases with a plate-like, but intertwined morphology. The primary segmentation is further refined to disentangle these geometrically complex precipitates into individual plate like parts by an unsupervised approach based on principle component analysis, or a U-Net based semantic segmentation trained on the former. Following the chemical and geometric analysis, detailed chemical distribution and segregation effects relative to the predominant plate-like geometry can be readily mapped without resorting to the initial voxelization.

description: Challenges in nursing, including an ageing population with increasingly complex health needs, an aging and decreasing global nursing workforce, and depressed government budgets, impact on the quality and availability of nursing students’ clinical placements as part of their education. Development and implementation of innovative activities are essential to ensure that students are both personally and professionally prepared for nursing practice. Simulation is an educational strategy adopted in nursing education to promote the safety and competence of nurses entering the clinical environment, and it offers a response to the problems around clinical placement. The current study investigated the simulated nursing practice activity of students in their first year of nursing education. The aims of this study were to explore and describe the experiences of students as nurses and patients in role play simulation and to develop a substantive theory through which to understand these experiences; to influence national simulation standards, policies, and guidelines; and to impact on the development of role play simulation activities for students in undergraduate nursing institutions. The research design adopted a grounded theory approach: incorporating the core elements of grounded theory, which frame all steps in the study. Data was gathered through semi-structured interviews through a purposive sample of 16 students in a New Zealand nursing institution. Findings emerging from the data revealed a substantive theory, connection in simulated nursing practice, consisting of the central category, connection, and its four principal categories: 1. discovering connections, 2. connecting with peers, 3.

Unearthing vulnerability of supply provision in logistics networks to the black swan events: Applications of entropy theory and network analysis
Creators: name: Dumrak, Jantanee
Publisher: name: Torrens University Australia
Year: 2022
Subjects: Supply chains

description: Over the past two decades, the fragility of modern Logistics Networks (LNs) has been exposed by unexpected events with extreme impacts outside the realm of regular expectations, which are known as the black swan events. As a response to the growing dysfunctions of the global LNs due to the detrimental effects of the black swan events, this article develops a quantitative vulnerability assessment method by paying simultaneous attention to various structural properties of these networks. It adopts three prototypical examples of centrality indices known as betweenness, closeness, and eigenvector centrality. This work also develops a vulnerability index from the joint entropy of centrality values, which can be interpreted as a certain extent of risk to disruptions in supply provision in LNs. The proposed entropy-based vulnerability index enables a far more accurate analysis of vulnerability by measuring the degree of homogeneity and heterogeneity of centrality values. The suggested index is considered as an objective function that must be minimized to reduce the deleterious effects of the black swan events. To illustrate the proposed vulnerability assessment method, this paper analyzes a real-world global maritime network, concluding that the juxtaposition of centrality measures provides a richer insight into the vulnerability analysis of LNs. The results also favor the fact that increasing the homogeneity of a network through decentralization yields lower vulnerability and builds extra robustness into the networks.

description: For automated driving, higher levels of automation pose new challenges in terms of safety. In this paper, we develop a generic behavior safety framework that maintains a safe vehicle state even in case of system failures. It is applicable to different configurations of automated driving system architectures. We verify the designed generic behavior safety framework by applying it to two different architectures from both projects PRORETA 5 and UNICARagil. The previously defined safety requirements are met with both applications, which indicates that the developed generic safety framework is also valid for other configurations of automated driving systems.

description: Data-driven cell tracking and segmentation methods in biomedical imaging require diverse and information-rich training data. In cases where the number of training samples is limited, synthetic computer-generated data sets can be used to improve these methods. This requires the synthesis of cell shapes as well as corresponding microscopy images using generative models. To synthesize realistic living cell shapes, the shape representation used by the generative model should be able to accurately represent fine details and changes in topology, which are common in cells. These requirements are not met by 3D voxel masks, which are restricted in resolution, and polygon meshes, which do not easily model processes like cell growth and mitosis. In this work, we propose to represent living cell shapes as level sets of signed distance functions (SDFs) which are estimated by neural networks. We optimize a fully-connected neural network to provide an implicit representation of the SDF value at any point in a 3D+time domain, conditioned on a learned latent code that is disentangled from the rotation of the cell shape. We demonstrate the effectiveness of this approach on cells that exhibit rapid deformations (Platynereis dumerilii), cells that grow and divide (C. elegans), and cells that have growing and branching filopodial protrusions (A549 human lung carcinoma cells). A quantitative evaluation using shape features and Dice similarity coefficients of real and synthetic cell shapes shows that our model can generate topologically plausible complex cell shapes in 3D+time with high similarity to real living cell shapes. Finally, we show how microscopy images of living cells that correspond to our generated cell shapes can be synthesized using an image-to-image model.

A brighter shade of pink: Magnus Hirschfeld, the third sex, and the sexual freedom movement in Germany
Creators: name: Mancini, Elena
Publisher: name: No Publisher Supplied
Year: 2007

description: Queer had a voice long before it became an avowed identity position in the late twentieth century. That voice belonged to Magnus Hirschfeld (1868-1935). Renowned mostly for his pioneering work as a sexologist and a gay rights activist, Hirschfeld embodied a liberal democratic ethic that allowed him to make significant contributions to some of the most pressing social issues of the late Wilhelmine and Weimar period. He devoted his life to sexual reform and social justice. Homosexuality, abortion rights, women's suffrage, the philosophical and political abolition of racism, and cultural cosmopolitanism were among the causes he embraced.Grounded in a cultural-historical approach that is sensitive to the significance of Hirschfeld's theoretical contributions and political advocacy for sexual equality, this study seeks to challenge the notion that the practical concerns of the gay and queer community are best served by queer theory. Taking issue with many queer theorists' all too facile dismissal of the emancipatory values of tolerance and Enlightenment universals in favor of the privileging of difference and narrow identity groups, my dissertation argues that a repudiation of Enlightenment universalism, most specifically the value of tolerance, will not advance the practical concerns--gay marriage, protection against hate crimes and full social and political enfranchisement--of the queer and gay community but rather ultimately lead such groups into a rights-deprived cul-de-sac. Far from advocating compromise or conformity within the queer community, my argument calls for a shift in emphasis and priorities within it that privileges equality and basic civil rights before defining narrow identity group interests. By illuminating Hirschfeld's coalitionist ethic--he formed crucial alliances with leaders of the Social Democratic Party and key organizers of minority group movements--cultural engagement, humanism and social outreach, my work not only recovers a significant piece of queer history but also furnish an ethos for the realization of practical goals within the queer community that has the potential of transforming current prejudices toward alternative sexual identities.

description: The purpose of this study is to help water utilities make more informed decisions about water reuse opportunities. We develop a new system model to optimize capture, storage, treatment, and conveyance of urban stormwater to infiltration ponds to supplement groundwater recharge. We compare the unit life cycle costs for different stormwater treatment trains through case study of Santa Clara County, CA. Key Findings include: a) There are opportunities to divert 12,000+ AFY from Coyote Creek and deliver to Los Gatos Recharge Ponds. This volume is >10x larger than volumes in previously identified projects. b) There is a highly nonlinear relationship among system cost, storage volume, treatment train selection, and total water deliveries to Los Gatos. c) Depending on system size and treatment train design, costs range from 2,000 – 7,000 $/MG, with substantially lower production costs than seawater desalination. d) The incremental benefit of storage is small between 0 – 10 MG.

description: Background: People with intellectual disabilities report similar everyday life stressors as the general population; however, they rate social stressors as having a significant negative impact on their wellbeing. This study investigated salient social stressors experienced by young people with intellectual disabilities. Method: Data was collected from thirteen college students with intellectual disabilities during three focus groups and analysed using Thematic Analysis. Results: Five themes were identified: understanding stress, pressure of increased responsibilities, stigma and exclusion, the company of others: fears and worries, support and resilience. The participants reflected on past and present sources of social stress and communicated their worries about social stress in the future. Conclusion: This study highlights the impact of social stress for these young people. It also identifies their understanding and coping skills. Future research could trial adapted psychological therapies with this population to help them manage these social stressors.

description: Every maximally monotone operator can be associated with a family of convex functions, called the Fitzpatrick family or family of representative functions. Surprisingly, in 2017, Burachik and Martínez-Legaz showed that the well-known Bregman distance is a particular case of a general family of distances, each one induced by a specific maximally monotone operator and a specific choice of one of its representative functions. For the family of generalized Bregman distances, sufficient conditions for convexity, coercivity, and supercoercivity have recently been furnished. Motivated by these advances, we introduce in the present paper the generalized left and right envelopes and proximity operators, and we provide asymptotic results for parameters. Certain results extend readily from the more specific Bregman context, while others only extend for certain generalized cases. To illustrate, we construct examples from the Bregman generalizing case, together with the natural "extreme" cases that highlight the importance of which generalized Bregman distance is chosen.

description: We study charm production in ultra-relativistic heavy-ion collisions by using the Parton-Hadron-String Dynamics (PHSD) transport approach. The initial charm quarks are produced by the Pythia event generator tuned to fit the transverse momentum spectrum and rapidity distribution of charm quarks from Fixed-Order Next-to-Leading Logarithm (FONLL) calculations. The produced charm quarks scatter in the quark-gluon plasma (QGP) with the off-shell partons whose masses and widths are given by the Dynamical Quasi-Particle Model (DQPM) which reproduces the lattice QCD equation-of-state in thermal equilibrium. The relevant cross section are calculated in a consistent way by employing the effective propagators and couplings from the DQPM. Close to the critical energy density of the phase transition, the charm quarks are hadronized into $D$ mesons through coalescence and/or fragmentation depending on transverse momentum. The hadronized $D$ mesons then interact with the various hadrons in the hadronic phase with cross sections calculated in an effective lagrangian approach with heavy-quark spin symmetry. Finally, the nuclear modification factor $\rm R_{AA}$ and the elliptic flow $v_2$ of $D^0$ mesons from PHSD are compared with the experimental data from the STAR Collaboration for Au+Au collisions at $\sqrt{s_{\rm NN}}$ =200 GeV. We find that in the PHSD the energy loss of $D$ mesons at high $p_T$ can be dominantly attributed to partonic scattering while the actual shape of $\rm R_{AA}$ versus $p_T$ reflects the heavy quark hadronization scenario, i.e. coalescence versus fragmentation. Also the hadronic rescattering is important for the $\rm R_{AA}$ at low $p_T$ and enhances the $D$-meson elliptic flow $v_2$.

description: In the post-LIGO era, there has been a lot of focus on primordial black holes (PBHs) heavier than $\sim 10^{15}$g as potential dark matter (DM) candidates. We point out that the branch of the PBH family that disappeared - PBHs lighter than $\sim 10^9$g that ostensibly Hawking evaporated away in the early Universe - also constitute an interesting frontier for DM physics. Hawking evaporation itself serves as a portal through which such PBHs can illuminate new physics, for example by emitting dark sector particles. Taking a simple DM scalar singlet model as a template, we compute the abundance and mass of PBHs that could have provided, by Hawking evaporation, the correct DM relic density. We consider two classes of such PBHs: those originating from curvature perturbations generated by inflation, and those originating from false vacuum collapse during a first-order phase transition. For PBHs of both origins we compute the gravitational wave (GW) signals emanating from their formation stage: from second-order effects in the case of curvature perturbations, and from sound waves in the case of phase transitions. The GW signals have peak frequencies in the MHz-GHz range typical of such light PBHs. We compute the strength of such GWs compatible with the observed DM relic density, and find that the GW signal morphology can in principle allow one to distinguish between the two PBH formation histories.

description: We study the Polyakov loop and the $Z_2$ symmetry in the lattice $Z_2+$Higgs theory in 4D Euclidean space using Monte Carlo simulations. The results show that this symmetry is realised in the Higgs symmetric phase for large number of temporal lattice sites. To understand the dependence on the number of temporal sites, we consider a one dimensional model by keeping terms of the original action corresponding to a single spatial site. In this approximation the partition function can be calculated exactly as a function of the Polyakov loop. The resulting free energy is found to have the $Z_2$ symmetry in the limit of large temporal sites. We argue that this is due to $Z_2$ invariance as well as dominance of the distribution or density of states corresponding to the action.

description: We consider several semidefinite programming relaxations for the max-$k$-cut problem, with increasing complexity. The optimal solution of the weakest presented semidefinite programming relaxation has a closed form expression that includes the largest Laplacian eigenvalue of the graph under consideration. This is the first known eigenvalue bound for the max-$k$-cut when $k>2$ that is applicable to any graph. This bound is exploited to derive a new eigenvalue bound on the chromatic number of a graph. For regular graphs, the new bound on the chromatic number is the same as the well-known Hoffman bound; however, the two bounds are incomparable in general. We prove that the eigenvalue bound for the max-$k$-cut is tight for several classes of graphs. We investigate the presented bounds for specific classes of graphs, such as walk-regular graphs, strongly regular graphs, and graphs from the Hamming association scheme.

description: Cyber threat intelligence is the provision of evidence-based knowledge about existing or emerging threats. Benefits from threat intelligence include increased situational awareness, efficiency in security operations, and improved prevention, detection, and response capabilities. To process, correlate, and analyze vast amounts of threat information and data and derive intelligence that can be shared and consumed in meaningful times, it is required to utilize structured, machine-readable formats that incorporate the industry-required expressivity while at the same time being unambiguous. To a large extent, this is achieved with technologies like ontologies, schemas, and taxonomies. This research evaluates the coverage and high-level conceptual expressivity of cyber-threat-intelligence-relevant ontologies, sharing standards, and taxonomies pertaining to the who, what, why, where, when, and how elements of threats and attacks in addition to courses of action and technical indicators. The results confirm that little emphasis has been given to developing a comprehensive cyber threat intelligence ontology, with existing efforts being not thoroughly designed, non-interoperable, ambiguous, and lacking proper semantics and axioms for reasoning.

description: Let A be a finitely presented associative monomial algebra. We study the category qgr(A) which is a quotient of the category of graded finitely presented A-modules by the finite-dimensional ones. As this category plays a role of the category of coherent sheaves on the corresponding noncommutative variety, we consider its bounded derived category. We calculate the categorical entropy of the Serre twist functor this derived category and show that it is equal to logarithm of the entropy of the algebra A itself. Moreover, we relate these two kinds of entropy with the topological entropy of the Ufnarovski graph of A and the entropy of the path algebra of the graph. If A is a path algebra of some quiver, the categorical entropy is equal to the logarithm of the spectral radius of the quiver's adjacency matrix.

Leagile Strategies for Optimizing the Delivery of Prefabricated House Building Projects

description: Australian housing supply has not been responded at a rate commensurate with its growing demand. Residential housing sector is facing this serious shortage issue by actively developing and effectively using new construction material, processes and practices for sustaining its competitive advantage over other construction sectors in the Australian context. The Construction 2020 report confirmed prefabrication/off-site manufacturing (OSM) as a critical vision for the Australian construction industry’s future, as OSM provides opportunities for not only increased productivity and safety, but also decreased cost. It also has the capability of meeting the growing housing demand within the extant level of skilled labour. By combining lean and agile concepts, OSM’s supply responsiveness and efficiency can be intensified. The current research studies the association between demand–supply housing imbalance factors using mixed methods from literature and interviews. Literature has documented four main factors that drive this imbalance: (1) housing completion time; (2) cost of a finished house; (3) customer preferences and (4) level of skilled labour. Interviews with 13 industry professionals identified the four main leagile strategies used to deliver prefabricated building projects. Literature and interview findings supported the development and validation of multicriteria decision-making (MCDM) model comprising and incorporating these factors (and subfactors) and the four leagile strategies. The choice of the appropriate strategy to address the studied factors within the Australian context was optimized using analytic hierarchy process (AHP). The results from the AHP model show the suitability of applying each strategy at different degrees as influenced by the tested factors.

description: The description of Wigner-friend scenarios -- in which external agents describe a closed laboratory containing a friend making a measurement -- remains problematic due to the ambiguous nature of quantum measurements. One option is to endorse assumptions leading to observer-dependent facts, given that the friend's measurement outcome is not defined from the point of view of the external observers. We introduce in this work a model in a relativistic context showing that these assumptions can also lead to measurement records that depend on the inertial reference frame in which the agents make their observations. Our model is based on an entangled pair shared by the friend and a distant agent performing space-like separated measurements. An external observer at rest relative to the closed laboratory and observers in a moving frame do not agree on the observed records, which are not Lorentz transforms of one another.

description: Статья посвящена анализу системы образования в Российской Федерации. Раскрыты проблемы российской системы обучения и тенденции ее развития. В целях соответствия Болонской системе возникла необходимость реформирования сферы образования, а именно изменения структуры и содержания образования, а также обеспечения гарантий качества образования. Новые модели современного высшего образования отвечают определенным требованиям, представленным во ФГОС. Трансформируя и адаптируя систему к современным образовательным реалиям, приходится сталкиваться с рядом проблем. Главная из них коммерциализация высшего образования, что приводит к выпуску социального продукта, сформированного в соответствии с потребностями заказчика, и классовому расслоению общества. Анализ статистических данных образовательной сферы позволил затронуть вопросы относительно необходимости внедрения более инновационных образовательных программ и высокого качества подготовки студентов в современной образовательной системе России. Недофинансирование и слабое управление в сфере образования России серьезно влияют на его качество, которое в последнее время существенно падает, поскольку большая часть средств, выделенных государством, направлена на реформу системы, но не на повышение качества образования.The article is devoted to the analysis of the education system in the Russian Federation. The problems of the Russian training system and the trends of its development are disclosed. In order to comply with the Bologna system, the need arose to reform the sphere of education, namely, changes in the structure and content of education, as well as guaranteeing the quality of education. New models of modern higher education meet certain requirements presented in the Federal State Educational Standard. Transforming and adapting the system to modern educational realities, one has to face a number of problems. The main one is the commercialization of higher education, which leads to the release of a social product, formed in accordance with the needs of the customer, and the class stratification of society. The analysis of educational statistics made it possible to raise questions regarding the need to introduce more innovative educational programs and the high quality of student preparation in the modern educational system of Russia. Underfunding and poor governance in the field of education in Russia seriously affect its quality, which has recently dropped significantly, since most of the funds allocated by the state are aimed at reforming the system, but not at improving the quality of education.

description: We consider 1D discrete Schrödinger operators with aperiodic potentials given by a Sturmian word, which is a natural generalisation of the Fibonacci Hamiltonian. Via a standard approximation by periodic potentials, we establish Hausdorff convergence of the corresponding spectra for the Schrödinger operators on the axis as well as for their compressions to the half-axis. Based on the half-axis results, we study the finite section method, which is another operator approximation, now by compressions to finite but growing intervals, that is often used to solve operator equations approximately. We find that, also for this purpose, the aperiodic case can be studied via its periodic approximants. Our results on the finite section method of the aperiodic operator are illustrated by confirming a result on the finite sections of the special case of the Fibonacci Hamiltonian.

description: In this paper, we propose a novel subspace learning framework for one-class classification. The proposed framework presents the problem in the form of graph embedding. It includes the previously proposed subspace one-class techniques as its special cases and provides further insight on what these techniques actually optimize. The framework allows to incorporate other meaningful optimization goals via the graph preserving criterion and reveals a spectral solution and a spectral regression-based solution as alternatives to the previously used gradient-based technique. We combine the subspace learning framework iteratively with Support Vector Data Description applied in the subspace to formulate Graph-Embedded Subspace Support Vector Data Description. We experimentally analyzed the performance of newly proposed different variants. We demonstrate improved performance against the baselines and the recently proposed subspace learning methods for one-class classification.

description: To investigate Casimir electromagnetic interaction in $N$ bodies, we implement multiple $δ$-function plates with electric and magnetic properties. We use their optical properties to study the Casimir energy between the plates by implementing multiple scattering formalism. We initially solve Green's functions for two and three plates configurations to obtain their reflection coefficients. Further, the coefficients are implemented in multiple scattering formalism, and a simple method was obtained to depict energy density distribution in the multiple scattering expansions using diagrammatic loops. The Casimir energy for $N$ bodies depends on multiple scattering parameter $Δ$; this parameter was distributed into nearest neighbour scattering and next-to-nearest neighbour scattering terms represented by different loops depending on reflection, transmission and propagation distance. In this manner, the Casimir energy density was generalized to $N$ plates by identifying a systematic pattern in the representation of diagrammatic loops.

description: In hot climatic regions, some kind of cooling system is necessary to avoid warmth and humidity. Many of the available cooling systems are not economic and sustainable. In this study, sustainable and feasible space/room cooling systems have been experimentally analyzed. A solar operated cooling system with two options have been designed and their performances are compared. Phase Change Material (PCM) is proposed to store thermal energy instead of a costly battery. A 1200-watt compressor and fin-type condenser are used to construct the vapor compression system. When the incoming air is passed through the cooling coil, it gets cool. For this cooling coil, 50 feet copper tube is used. The front side copper tube diameter of the fan is 3/8 inch and the backside tube diameter is 1/2 inch. It took about 35 minutes and 5 minutes to minimize the room temperature at the desired level in the case of the stand fan and duct fan, respectively. Furthermore, the stand fan and duct fan systems reduced 3 °C and 6 °C of the outside temperature, respectively.
