description: Asterias rubens is feeding at beds of Mytilus edulis and living on hard substrate between the mussels. The behaviour of Asterias rubens was studied in order to evaluate the choice of substrate without wave exposure, predators or prey available. In laboratory experiments, favoured selection of Fucus vesiculosus, Crassostrea gigas and covered stone was observed. Our observations showed preferential choice of shadowed substrate and revealed that presence of conspecifics did not affect the substrate choice of Asterias rubens juveniles. The experiments indicated that aggregation of individuals is not avoided, but no evidence is found for intended aggregation. The study demonstrated that the substrate choice behaviour of Asterias can’t be described as randomly.
description: Asterias rubens frisst an Betten von Mytilus edulis und lebt auf hartem Substrat zwischen den Muscheln. Das Verhalten von Asterias rubens wurde untersucht, um die Wahl des Substrats ohne Wellenexposition, Räuber oder Beute zu bewerten. In Laborexperimenten wurde eine bevorzugte Selektion von Fucus vesiculosus, Crassostrea gigas und bedecktem Stein beobachtet. Unsere Beobachtungen zeigten eine bevorzugte Wahl des beschatteten Substrats und zeigten, dass die Anwesenheit von Artgenossen die Substratwahl von Asterias rubens (juvenil) nicht beeinflusste. Die Experimente zeigten, dass eine Aggregation von Individuen nicht vermieden wird, aber es werden keine Hinweise auf eine beabsichtigte Aggregation gefunden. Die Studie zeigte, dass das Substratwahlverhalten von Asterias nicht als zufällig beschrieben werden kann.

description: We identify universal spatial fluctuations in systems with non trivial spin dynamics. To this end we calculate by exact numerical diagonalization a variety of experimentally relevant correlations between spinor amplitudes, spin polarizations and spin currents both in the bulk and near the boundary of a confined two-dimensional clean electron gas in the presence of spin-orbit interaction and a single magnetic impurity. We support or claim of universality with the excellent agreement between the numerical results and system-independent spatial correlations of a random field defined on both the spatial and spin degrees of freedom. A rigorous identity relating our universal predictions with response functions provides a direct physical interpretation of our results in the framework of linear response theory.

description: The aim of this study was to define the clinical, histopathologic, and prognostic features associated with simultaneous positivity for anti-dsDNA, -nucleosome, and -histone antibodies (3-pos) in Korean patients with biopsy-proven lupus nephritis (LN). The 102 patients included in the study had undergone kidney biopsy prior to the start of induction treatment, were treated with immunosuppressives, and followed-up for >12 months. In total, 44 (43.1%) of the 102 LN patients were 3-pos. Patients with 3-pos had a higher SLEDAI-2K score (p = .002), lower lymphocyte count (p = .004), and higher rates of proteinuria > 3.5 g/24 h (p = .039) and positivity for urinary sediments (p = .005) at the time of renal biopsy than non-3-pos patients. 3-pos patients had a more proliferative form of LN (p = .045) in the renal histopathologic findings, and as co-positivity gradually increased from 0 to 3, the total activity score in the renal biopsy findings increased significantly (p = .033). In addition, 3-pos patients had a more rapid eGFR decline than non-3-pos patients after a follow-up of 83.2 months (p = .016). Our findings suggest that 3-pos is related to severe LN and that 3-pos patients are more likely to experience a rapid decline of renal function than non-3-pos patients.KEY MESSAGEPatients with co-positivity for anti-dsDNA, -nucleosome, and -histone antibodies (3-pos) had higher disease activity and a worse renal histopathology than those without co-positivity.3-pos patients had a more rapid decline of renal function than non-3-pos patients.

description: Effective scaffolds for bone tissue-engineering are those that combine adequate mechanical and chemical performance with osseointegrative, angiogenetic and anti-bacterial modes of bioactivity. To address these requirements via a combined approach, we additively manufactured square strut scaffolds by robocasting precipitation-derived strontium/copper co-substituted diopside. Microstructure, mechanical performance, bioactivity, biocompatibility, and antibacterial activity were examined. The results show that the presence of strontium and copper in the diopside lattice reduces the grain size and increases the density of the ceramics. The compressive strength, hardness, and fracture toughness of the diopside showed improvement, attributed to a finer microstructure and improved sintering. Scaffolds had excellent compressive strength with a high porosity (68 to 72 %), which is attributed to the structure of the stacked square struts. All materials showed good in vitro bioactivity and favorable proliferation of osteogenic sarcoma cells, while strontium and copper co-doped materials exhibited the strongest anti-Escherichia coli activity. We show that across multiple indicators this system offers pathways towards high-performance bone substitutes.
title: How do Chinese international business students develop bridging social capital in Australia to improve their self-perception of their employability?

description: Immediately prior to the COVID-19 pandemic international education contributed over $37 billion to the Australian economy. Most students came from China and chose an Australian education because they expected it would improve their career prospects. However, evidence shows that even prior to COVID-19, international students were struggling to find opportunities to develop their employability, leading to dissatisfaction with their investment. Australia’s third largest export industry may be at risk unless the problem of international student employability is addressed. Social capital is a key factor of employability, however international students are stripped of their social capital as soon as they arrive in Australia, instantly compromising their employability. The purpose of this research was to gain a deeper understanding of the challenges that six international Chinese business students at the University of Sydney experienced as they rebuilt their social capital in Australia, and how they overcame those challenges to improve their self-perception of their employability. Interpretative Phenomenological Analysis (IPA) was used as the methodological approach as it allowed an in-depth exploration and interpretation of the meaning that the participants made of those experiences. The research found the challenges were a result of the tensions between the cultural expectations of Australians and the participants’ Confucian heritage upbringing. The participants were able to navigate these tensions by having a growth mindset—they reframed challenges as learning opportunities. This enabled them to develop their bridging social capital, improve their employability and achieve their goal of finding work in Australia.

description: Retrieving relevant items that match users' queries from billion-scale corpus forms the core of industrial e-commerce search systems, in which embedding-based retrieval (EBR) methods are prevailing. These methods adopt a two-tower framework to learn embedding vectors for query and item separately and thus leverage efficient approximate nearest neighbor (ANN) search to retrieve relevant items. However, existing EBR methods usually ignore inconsistent user behaviors in industrial multi-stage search systems, resulting in insufficient retrieval efficiency with a low commercial return. To tackle this challenge, we propose to improve EBR methods by learning Multi-level Multi-Grained Semantic Embeddings(MMSE). We propose the multi-stage information mining to exploit the ordered, clicked, unclicked and random sampled items in practical user behavior data, and then capture query-item similarity via a post-fusion strategy. We then propose multi-grained learning objectives that integrate the retrieval loss with global comparison ability and the ranking loss with local comparison ability to generate semantic embeddings. Both experiments on a real-world billion-scale dataset and online A/B tests verify the effectiveness of MMSE in achieving significant performance improvements on metrics such as offline recall and online conversion rate (CVR).
Informed RRT*: Optimal Sampling-based Path Planning Focused via Direct Sampling of an Admissible Ellipsoidal Heuristic

description: Rapidly-exploring random trees (RRTs) are popular in motion planning because they find solutions efficiently to single-query problems. Optimal RRTs (RRT*s) extend RRTs to the problem of finding the optimal solution, but in doing so asymptotically find the optimal path from the initial state to every state in the planning domain. This behaviour is not only inefficient but also inconsistent with their single-query nature. For problems seeking to minimize path length, the subset of states that can improve a solution can be described by a prolate hyperspheroid. We show that unless this subset is sampled directly, the probability of improving a solution becomes arbitrarily small in large worlds or high state dimensions. In this paper, we present an exact method to focus the search by directly sampling this subset. The advantages of the presented sampling technique are demonstrated with a new algorithm, Informed RRT*. This method retains the same probabilistic guarantees on completeness and optimality as RRT* while improving the convergence rate and final solution quality. We present the algorithm as a simple modification to RRT* that could be further extended by more advanced path-planning algorithms. We show experimentally that it outperforms RRT* in rate of convergence, final solution cost, and ability to find difficult passages while demonstrating less dependence on the state dimension and range of the planning problem.

Codependent VAR Models and the Pseudo-Structural Form

description: This paper investigates whether codependence restrictions can be uniquely imposed on VAR and VEC models via the so-called pseudo-structural form used in the literature. Codependence of order q is given if a linear combination of autocorrelated variables eliminates the serial correlation after q lags. Importantly, maximum likelihood estimation and likelihood ratio testing are only possible if the codependence restrictions can be uniquely imposed. Applying the pseudo-structural form, our study reveals that this is not generally the case, but that unique imposition is guaranteed in several important special cases. Moreover, we discuss further issues, in particular upper bounds of the codependence order.

description: Two deterministic reaction-diffusion models are introduced to simulate a general molecular mechanism, which can produce a variety of different pigmentation patterns on the shells of molluscs. We focused on the reconstruction of patterns observed on the surface of shells collected in the Wadden Sea of Northern Germany, which include horizontal and vertical stripes, as well as oblique lines and dots. The patterns were analyzed in respect to their parameter sensitivity and varying initial conditions. We show that the models have high potential to reproduce very different patterns with only modest changes in the parameters. Such theoretical approaches can be used to understand the mechanisms involved in pigmentation.
description: Zwei deterministische Reaktions-Diffusions-Modelle werden eingeführt, um einen allgemeinen molekularen Mechanismus zu simulieren, der eine Vielzahl unterschiedlicher Pigmentierungsmuster auf den Schalen von Weichtieren erzeugen kann. Wir konzentrierten uns auf die Rekonstruktion von Mustern, die auf der Oberfläche von im norddeutschen Wattenmeer gesammelten Muscheln beobachtet wurden, die horizontale und vertikale Streifen sowie schräge Linien und Punkte umfassen. Die Muster wurden hinsichtlich ihrer Parameterempfindlichkeit und variierenden Anfangsbedingungen analysiert. Wir zeigen, dass die Modelle ein hohes Potenzial haben, sehr unterschiedliche Muster mit nur geringfügigen Änderungen der Parameter zu reproduzieren. Solche theoretischen Ansätze können verwendet werden, um die an der Pigmentierung beteiligten Mechanismen zu verstehen.

description: We study an SU(3) gauge theory with Nf=8 degenerate flavors of light fermions in the fundamental representation. Using the domain wall fermion formulation, we investigate the light hadron spectrum, chiral condensate and electroweak S parameter. We consider a range of light fermion masses on two lattice volumes at a single gauge coupling chosen so that IR scales approximately match those from our previous studies of the two- and six-flavor systems. Our results for the Nf=8 spectrum suggest spontaneous chiral symmetry breaking, though fits to the fermion mass dependence of spectral quantities do not strongly disfavor the hypothesis of mass-deformed infrared conformality. Compared to Nf=2 we observe a significant enhancement of the chiral condensate relative to the symmetry breaking scale F, similar to the situation for Nf=6. The reduction of the S parameter, related to parity doubling in the vector and axial-vector channels, is also comparable to our six-flavor results.

description: As wireless devices boom, and bandwidth-hungry applications (e.g., video and cloud uploading) get popular, today's Wireless Local Area Networks (WLANs) become not only crowded but also stressed at throughput. Multi-user Multiple-Input and Multiple-Output (MU-MIMO), an advanced form of MIMO, has gained attention due to its huge potential in improving the performance of WLANs. This paper surveys random access based MAC protocols for MU-MIMO enabled WLANs. It first provides background information about the evolution and the fundamental MAC schemes of IEEE 802.11 Standards and Amendments, and then identifies the key requirements of designing MU-MIMO MAC protocols for WLANs. After that, the most representative MU-MIMO MAC proposals in the literature are overviewed by benchmarking their MAC procedures and examining the key components, such as the channel state information acquisition, de/pre-coding and scheduling schemes. Classifications and discussions on important findings of the surveyed MAC protocols are provided, based on which, the research challenges for designing effective MU-MIMO MAC protocols, as well as the envisaged MAC's role in the future heterogeneous networks, are highlighted.

description: Hyperentanglement, defined as the simultaneous entanglement in several independent degrees of freedom (DOFs) of a quantum system, is a fascinating resource in quantum information processing with its outstanding merits. Here we propose heralded hyperentanglement concentration protocols (hyper-ECPs) to concentrate an unknown partially less polarization-spatial hyperentangled Bell state with available linear optics and common single-photon detectors. By introducing time-delay DOFs, the schemes are highly efficient in that the success of the scheme can be accurately heralded by the detection signatures, and postselection techniques or photon-number-resolving detectors, necessary for previous experiments, are not required. Additionally, our linear optical architectures allow certain states, where concentration fails, to be recyclable, and a trick makes the success probabilities of our schemes higher than those of previous linear optical hyper-ECPs.

Monte Carlo simulation of stoquastic Hamiltonians

Year: 2014
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Stoquastic Hamiltonians are characterized by the property that their off-diagonal matrix elements in the standard product basis are real and non-positive. Many interesting quantum models fall into this class including the Transverse field Ising Model (TIM), the Heisenberg model on bipartite graphs, and the bosonic Hubbard model. Here we consider the problem of estimating the ground state energy of a local stoquastic Hamiltonian $H$ with a promise that the ground state of $H$ has a non-negligible correlation with some `guiding' state that admits a concise classical description. A formalized version of this problem called Guided Stoquastic Hamiltonian is shown to be complete for the complexity class MA (a probabilistic analogue of NP). To prove this result we employ the Projection Monte Carlo algorithm with a variable number of walkers. Secondly, we show that the ground state and thermal equilibrium properties of the ferromagnetic TIM can be simulated in polynomial time on a classical probabilistic computer. This result is based on the approximation algorithm for the classical ferromagnetic Ising model due to Jerrrum and Sinclair (1993).

description: We systematically analyze a broad class of dual heterotic and F-theory models that give four-dimensional supergravity theories, and compare the geometric constraints on the two sides of the duality. Specifically, we give a complete classification of models where the heterotic theory is compactified on a smooth Calabi-Yau threefold that is elliptically fibered with a single section and carries smooth irreducible vector bundles, and the dual F-theory model has a corresponding threefold base that has the form of a P^1 bundle. We formulate simple conditions for the geometry on the F-theory side to support an elliptically fibered Calabi-Yau fourfold. We match these conditions with conditions for the existence of stable vector bundles on the heterotic side, and show that F-theory gives new insight into the conditions under which such bundles can be constructed. In particular, we find that many allowed F-theory models correspond to vector bundles on the heterotic side with exceptional structure groups, and determine a topological condition that is only satisfied for bundles of this type. We show that in many cases the F-theory geometry imposes a constraint on the extent to which the gauge group can be enhanced, corresponding to limits on the way in which the heterotic bundle can decompose. We explicitly construct all (4962) F-theory threefold bases for dual F-theory/heterotic constructions in the subset of models where the common twofold base surface is toric, and give both toric and non-toric examples of the general results.

description: In this paper we introduce the notion of $\mathcal I^{\mathcal K}$-Cauchy function, where $\mathcal I$ and $\mathcal K$ are ideals on the same set. The $\mathcal I^{\mathcal K}$-Cauchy functions are a generalization of $\mathcal I^*$-Cauchy sequences and $\mathcal I^*$-Cauchy nets. We show how this notion can be used to characterize complete uniform spaces and we study how $\mathcal I^{\mathcal K}$-Cauchy functions and $\mathcal I$-Cauchy functions are related. We also define and study $\mathcal I^{\mathcal K}$-divergence of functions.

Strategic Leadership and Innovation: Navigating the Challenges of Modern Business Management
Creators: name: Rasmita Karki
Publisher: name: Zenodo

Subjects: Innovation; strategic leadership; business management; organizational culture; modern business.

description: Abstract: This paper discussed the important role of strategic leadership in the innovation process in contemporary business management. On this regard, strategic leadership can be viewed as a leading force or driver for innovation. The study aimed at answering how leadership involvement influences the adoption of new ideas and the degree of innovation amongst professionals. It applied a quantitative research design using a validated survey instrument, with 50 respondents from different industries. The questions included measurements for the openness of the respondents to innovation, their creativeness in solving problems, and their leadership involvement in their organizations. Data gathered from the surveys were analyzed in terms of the distribution of the levels of innovations of the respondents and how leadership involvement correlated with innovation adoption. The findings of the study obtained a very significant difference in the level of innovation, grouped into five classes of diffusers, including Innovators, Early Adopters, Early Majority, Late Majority, and Laggards/Traditionalists. To be more specific, among them, 20% were Innovators, while 30% of the respondents were Early Adopters, 20% were Early Majority, 20% Late Majority, and the remaining 10% were Laggards/Traditionalists. This distribution suggests that, while a significant portion of the population is easily open to new ideas and tends to try them first, there is another equally significant fraction that remains more circumspect and more likely to continue doing things the conventional way. Leadership involvement was very strongly correlated with increased innovation. This means that the more the respondents were involved in organizational leadership matters, the higher they scored on the innovation scale, thus denoting a greater disposition toward new ideas and an initiator of change within their respective teams. Using these data, the researchers rejected two null hypotheses: first, there is no significant difference in the level of innovation among the respondents; and second, there is no significant relationship between leadership involvement and adoption of new ideas. The study concludes that strategic leadership development and a culture supportive and rewarding of innovation are prerequisites for any organization in the current fast-moving and changing business environment. It enables the business to harness its resources to better navigate modern markets and sustain long-term success. This includes recommendations for programs on leadership training focused on innovation and initiatives that encourage creative thinking and experimentation within teams.
Identifying the Shocks behind Business Cycle Asynchrony in Euroland
Creators: name: Trenkler, Carsten

description: This paper investigates which shocks drive asynchrony of business cycles in the euro area. Thereby, it unites two strands of literature, those on common features and on structural VAR analysis. In particular, we show that the presence of a common cycle implies collinearity of structural impulse responses. Several Wald tests are applied to the latter hypothesis. Results reveal that differences in the GDP dynamics in several peripheral countries compared to a euro zone core are triggered by idiosyncratic, and to a lesser extent also world, shocks. Additionally, real shocks prove relevant rather than nominal ones.

A non-equilibrium quantum Landauer principle

description: Using the operational framework of completely positive, trace preserving operations and thermodynamic fluctuation relations, we derive a lower bound for the heat exchange in a Landauer erasure process on a quantum system. Our bound comes from a non-phenomenological derivation of the Landauer principle which holds for generic non-equilibrium dynamics. Furthermore the bound depends on the non-unitality of dynamics, giving it a physical significance that differs from other derivations. We apply our framework to the model of a spin-1/2 system coupled to an interacting spin chain at finite temperature.

description: This study examines the complex structure of prey and predator interactions, which are regulated by a variety of factors. Here, we are focusing on the prey size preference of the starfish Asterias rubens and its prey, the bivalve Mytilus edulis and its dependency on the size of the predator. Both species co-occur in the Wadden Sea of Sylt, Germany, where our experiment took place. In the course of this study we found that individuals of Asterias rubens favor mid-sized individuals of Mytilus edulis independently of their own size. Furthermore, our study revealed that medium-sized sea stars show the highest amount of activity in general.
description: Diese Studie untersucht die komplexe Struktur von Beute- und Räuberinteraktionen, die durch eine Vielzahl von Faktoren reguliert werden. Hier konzentrieren wir uns auf die Beutegrößenpräferenz des Seesterns Asterias rubens und seiner Beute, der Muschel Mytilus edulis und deren Abhängigkeit von der Größe des Räubers. Beide Arten kommen gemeinsam im Wattenmeer von Sylt vor, wo unser Experiment stattfand. Im Rahmen dieser Studie fanden wir heraus, dass Individuen von Asterias rubens unabhängig von ihrer eigenen Größe mittelgroße Individuen von Mytilus edulis bevorzugen. Darüber hinaus zeigte unsere Studie, dass mittelgroße Seesterne im Allgemeinen die höchste Aktivität aufweisen.

description: We investigate indirect constraints on the top partner within the minimal fermionic top partner model. By performing a global fit of the latest Higgs data, $B_s \to μ^+μ^-$ measurements and the electroweak precision observables we find that the top partner with the mass up to 830 GeV is excluded at $2σ$ level. Our bound on the top partner mass is much stronger than the bounds obtained from the direct searches at the LHC. Under the current constraints the fine-tuning measure is less than 9% and the branching ratio of $T \to tZ$ is bounded between 14% and 25%. We also find that precise measurements of Higgs couplings at 240 GeV TLEP will constrain the top partner mass in multi-TeV region.

description: In the presence of magnetic helicity, inverse transfer from small to large scales is well known in magnetohydrodynamic (MHD) turbulence and has applications in astrophysics, cosmology, and fusion plasmas. Using high resolution direct numerical simulations of magnetically dominated self-similarly decaying MHD turbulence, we report a similar inverse transfer even in the absence of magnetic helicity. We compute for the first time spectral energy transfer rates to show that this inverse transfer is about half as strong as with helicity, but in both cases the magnetic gain at large scales results from velocity at similar scales interacting with smaller-scale magnetic fields. This suggests that both inverse transfers are a consequence of a universal mechanisms for magnetically dominated turbulence. Possible explanations include inverse cascading of the mean squared vector potential associated with local near two-dimensionality and the shallower $k^2$ subinertial range spectrum of kinetic energy forcing the magnetic field with a $k^4$ subinertial range to attain larger-scale coherence. The inertial range shows a clear $k^{-2}$ spectrum and is the first example of fully isotropic magnetically dominated MHD turbulence exhibiting weak turbulence scaling.
