description: This paper proposes a self-adaptation mechanism to manage the resources allocated to the different species comprising a cooperative coevolutionary algorithm. The proposed approach relies on a dynamic extension to the well-known multi-armed bandit framework. At each iteration, the dynamic multi-armed bandit makes a decision on which species to evolve for a generation, using the history of progress made by the different species to guide the decisions. We show experimentally, on a benchmark and a real-world problem, that evolving the different populations at different paces allows not only to identify solutions more rapidly, but also improves the capacity of cooperative coevolution to solve more complex problems.

description: We introduce a simple model, a binary mixture of patchy particles, which has been designed to form a gel upon heating. Due to the specific nature of the particle interactions, notably the number and geometry of the patches as well as their interaction energies, the system is a fluid both at high and at low temperatures, whereas at intermediate temperatures the system forms a solid-like disordered open network structure, i.e. a gel. Using molecular dynamics we investigate the static and dynamic properties of this system.

description: Most millisecond pulsars with low-mass companions are in systems with either helium-core white dwarfs or non-degenerate ("black widow" or "redback") stars. A candidate counterpart to PSR J1816+4510 was identified by Kaplan et al. (2012) whose properties were suggestive of both types of companions although identical to neither. We have assembled optical spectroscopy of the candidate companion and confirm that it is part of the binary system with a radial velocity amplitude of 343+/-7 km/s, implying a high pulsar mass, Mpsr*sin^3i=1.84+/-0.11 Msun, and a companion mass Mc*sin^3i=0.192+/-0.012 Msun, where i is the inclination of the orbit. The companion appears similar to proto-white dwarfs/sdB stars, with a gravity log(g)=4.9+/-0.3, and effective temperature 16000+/-500 K. The strongest lines in the spectrum are from hydrogen, but numerous lines from helium, calcium, silicon, and magnesium are present as well, with implied abundances of roughly ten times solar (relative to hydrogen). As such, while from the spectrum the companion to PSR J1816+4510 is superficially most similar to a low-mass white dwarf, it has much lower gravity, is substantially larger, and shows substantial metals. Furthermore, it is able to produce ionized gas eclipses, which had previously been seen only for low-mass, non-degenerate companions in redback or black widow systems. We discuss the companion in relation to other sources, but find we understand neither its nature nor its origins. Thus, the system is interesting for understanding unusual stellar products of binary evolution, as well as, independent of its nature, for determining neutron-star masses.

description: Companies and their factories are in a state of permanent change. Factory planning is interested in anticipating the changes that will occur and thinking ahead structural adjustments by dimensioning the operating resources, personnel and space. Often incremental adjustments over the space are no longer sufficient, so that further investments become necessary. Large factory planning projects, such as a greenfield or expansion planning, usually require extensive capital, which has a huge impact on a company's liquidity. The correct evaluation of the economic efficiency of a factory planning project, i.e. the comparison of costs and revenues, is therefore essential. Investment feasibility studies can help companies choosing a proper project. In such an early phase, investments have to be planned and initiated under increasing uncertainty. However, with common methods and tools, a precise evaluation of the investments costs in an early planning phase is only possible to a limited extent. Consequently, the risk of misinvestment increases. Factory planning experts are therefore dependent on tools and methods that minimise this risk through a precise calculation of investment costs under uncertainties. This article addresses the related challenges, shows the need for an improved decision support, and give a first framework to face these challenges.

description: We present a detailed analysis of the UV spectrum of the calibration star Bd+28 4211 using high-quality spectra obtained with the HST and FUSE satellites. To this aim, we compare quantitatively the observed data with model spectra obtained from state-of-the-art NLTE metal line-blanketed model atmospheres and synthetic spectra calculated with TLUSTY and SYNSPEC. We thus determine in a self-consistent way the abundances of eleven elements with well-defined lines in the UV, namely those of C, N, O, F, Mg, Si, P, S, Ar, Fe, and Ni. The derived abundances range from about solar to 1/10 solar. We find that the overall quality of the derived spectral fits is very satisfying. Our spectral analysis can be used to constrain rather tigthly the effective temperature of Bd+28 to a value of teff = 82,000 +/- 5000 K. We also estimate conservatively that its surface gravity falls in the range log g = 6.2 -0.1/+0.3. Assuming that the Hipparcos measurement for Bd+28 is fully reliable and that our model atmospheres are reasonably realistic, we can reconcile our spectroscopic constraints with the available parallax measurement only if the mass of Bd+28 is significantly less than the canonical value of 0.5 msun for a representative post-EHB star.

title: Eared Grebe Nesting Ecology and Chronology Along the Great Salt Lake, Utah
Creators: name: Delahoussaye, Leah M.
Publisher: name: Utah State University
Year: 2019

description: Eared Grebes (Podiceps nigricollis) are migratory birds that build their nests over water and in large groups called colonies. Their typical breeding range is in central southern Canada and northern United States; however, a previously uncertain number of Eared Grebes (grebes) also nest around the Great Salt Lake (GSL), Utah, at the southern edge of their breeding range. Little is known about the habitat requirements for grebe nesting colonies at such low latitudes and if they are different from colonies found elsewhere. My objectives for this research were to determine the status of the grebe nesting population as well as their habitat characteristics along the GSL in freshwater wetlands. I found over 4,280 grebe nests distributed among 35 colonies. Grebes built nests by mounding submerged aquatic vegetation (SAV) beginning the first week of June. The results from my habitat study show that grebes prefer to nest in areas with an average water depth of 48 cm, high invertebrate density, and abundant areas of floating SAV. Water depth and vegetation type at colony sites as well as timing of nesting and average number of eggs per nest of GSL colonies differed from colonies located at more northern latitudes. The differences in nesting could be attributed to the need to wait for SAV to grow and form mats on the water’s surface, or a need to wait for their food source to reach harvestable size.

After grebes leave their nesting grounds, they stop at the GSL where they prepare for their final migration southward by consuming their fill of brine shrimp (Artemia franciscana). Brine shrimp are tiny invertebrates that are well-adapted to salty environments; they produce hard-walled eggs called cysts which are of great economic value and are commercially harvested from the GSL. I compared cyst viability, which is the percentage of cysts in a condition conducive to hatching, for cysts that had passed through the digestive tract of grebes and cysts samples obtained from the GSL. Only 30% of the cysts that had passed through grebes were viable, whereas 63% of cysts from the GSL were viable.
title: Isentropic Efficiency and Theoretical Analysis of the Planetary Rotor Expander

Publisher: name: Utah State University

description: Expanders allow pressurized fluids to undergo a pressure decrease in a controlled environment via volumetric growth to extract fluid energy. There are many types of expanders, and the objective of this thesis is to model the efficiencies of the planetary rotor expander (PRE), a century-old design undeveloped due to insufficient manufacturing capabilities (until recently). Geometric relationships are derived and mathematical models are generated to determine the efficiency of the PRE as a function of design variables. Two industrially relevant case studies show that, to maximize isentropic efficiency, the planetary rotor expander (PRE) rotational frequency is maximized and rotor geometry optimized.

description: The propagation of gamma-rays over cosmological distances is the subject of extensive theoretical and observational research at GeV and TeV energies. The mean free path of gamma-rays in the cosmic web is limited above 100 GeV due to the production of electrons and positrons on the cosmic optical and infrared backgrounds. Electrons and positrons cool in the intergalactic medium while gyrating in its magnetic fields, which could cause either its global heating or the production of lower-energy secondary gamma-rays. The energy distribution of gamma-rays surviving the cosmological journey carries observed absorption features that gauge the emissivity of baryonic matter over cosmic time, constrain the distance scale of $Λ$CDM cosmology, and limit the alterations of the interaction cross section. Competitive constraints are in particular placed on the cosmic star-formation history as well as on phenomena expected from quantum gravity and string theory, such as the coupling to hypothetical axion-like particles or the violation of Lorentz invariance. Recent theoretical and observational advances offer a glimpse of the multi-wavelength and multi-messenger path that the new generation of gamma-ray observatories is about to open.

title: Electronic Transmutation: An Aid for the Rational Design of New Chemical Materials Using the Knowledge of Bonding and Structure of Neighboring Elements
Creators: name: Lundell, Katie A.
Publisher: name: Utah State University
Year: 2019

description: Everything in the universe is made up of elements from the periodic table. Each element has its own role that it plays in the formation of things it makes up. For instance, pencil lead is graphite. A series of honeycomb-like structures made up of carbon stacked on top of one another. Carbon’s neighbor to the left, boron doesn’t like to form such stacked honeycomb-like structures. But, what if there was a way to make boron act like carbon so it did like to form such structures? That question is the basis of the electronic transmutation concept presented in this dissertation. Electronic transmutation states that an element, such as boron, can behave structurally like carbon (form stacked honeycomb structures) if you make them valence (outer most) isoelectronic (“iso”- same; “electronic”- electrons), so both would have the same number of outer most electrons. As a result, chemists would have a new tool to aid in the rational design of new materials.

description: From past experiments the average power density spectrum (PDS) of GRBs with unknown redshift was found to be modelled from 0.01 to 1 Hz with a power-law, f^(-alpha), with alpha broadly consistent with 5/3. Recent analyses of the Swift/BAT catalogue showed analogous results in the 15-150 keV band. We carried out the same analysis on the bright GRBs detected by BeppoSAX/GRBM and Fermi/GBM. The BeppoSAX/GRBM data, in the energy range 40-700 keV and with 7.8 and 0.5-ms time resolutions, allowed us to explore for the first time the average PDS at very high frequencies (up to 1 kHz) and reveal a break around 1-2 Hz, previously found in CGRO/BATSE data. The Fermi/GBM data, in the energy band 8-1000 keV, allowed us to explore for the first time the average PDS within a broad energy range. Our results confirm and extend the energy dependence of the PDS slope, according to which harder photons have shallower PDS.

Classical singularity is avoided and replaced by a quantum bounce in this model. It is shown that, quantum gravity effects predict a threshold scale below which no horizon can form as the collapse evolves towards the bounce.

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We introduce a characterization of disclination lines in three dimensional nematic liquid crystals as a tensor quantity related to the so called rotation vector around the line. This quantity is expressed in terms of the nematic tensor order parameter $\mathbf{Q}$, and shown to decompose as a dyad involving the tangent vector to the disclination line and the rotation vector. Further, we derive a kinematic law for the velocity of disclination lines by connecting this tensor to a topological charge density as in the Halperin-Mazenko description of defects in vector models. Using this framework, analytical predictions for the velocity of interacting line disclinations and of self-annihilating disclination loops are given and confirmed through numerical computation.

description: The time evolution of a single particle in a harmonic trap with time dependent frequency omega(t) is well studied. Nevertheless here we show that, when the harmonic trap is opened (or closed) as function of time while keeping the adiabatic parameter mu = [d omega(t)/dt]/omega(t)^2 fixed, a sharp transition from an oscillatory to a monotonic exponential dynamics occurs at mu = 2. At this transition point the time evolution has a third-order exceptional point (EP) at all instants. This situation, where an EP of a time-dependent Hermitian Hamiltonian is obtained at any given time, is very different from other known cases. Our finding is relevant to the dynamics of a single ion in a magnetic, optical, or rf trap, and of diluted gases of ultracold atoms in optical traps.

description: A new Maple toolchain for generating rigid body dynamics in symbolic form for robot manipulators is presented. The peculiarity compared to existing tools lies in the framework of Bash scripts controlling the full workflow of the toolchain with a high degree of automation. The optimized Matlab code generated by Maple is automatically converted to function files with proper documentation and input assertions. This renders manual post-processing of the results unnecessarily. The focus of the paper is on the implemented unit-testing framework according to the method of test-driven development. By providing the test framework together with the generated code in a stand-alone version, a good test coverage and a good software quality can be achieved. The results of the open source project provide a basis for dynamics simulations for robot dimensional synthesis or in model-based control of robot manipulators in research or in industrial context. The general software approach can be applied to other fields where theoretical models are derived with Maple.

description: We discuss inclusive production of open charm in proton-proton scattering at LHC. The calculation is performed within the $k_t$-factorization approach. Different models of unintegrated gluon distributions (UGDF) from the literature are used. The theoretical transverse momentum as well as (pseudo)rapidity distributions of charmed mesons are compared with recent experimental data of ATLAS, ALICE and LHCb collaborations. Only the calculation with Kimber-Martin-Ryskin (KMR) UGDF gives results comparable to experimental ones. All other popular models of UGDF significantly underpredict experimental data. Several sources of uncertainties of the theoretical predictions are also studied in details. In addition we discuss correlations between $D$ and $\bar D$ mesons. Good description of experimental distribution in invariant mass and in relative azimuthal angle between $D$ and $\bar D$ mesons is achieved for the KMR UGDF. The considered correlation observables measured by the LHCb experiment were not discussed in other approaches in the literature.

description: Factories are characterised by a long life cycle and substantial investment costs. In particular, factory planning and reorganisation lead to capital-intensive investments and have a significant influence on the liquidity of companies. Reliable data are the basic prerequisite for a valid economic assessment of intended factory planning projects. However, especially in early planning phases, the available data are often uncertain and inaccurate. This problem significantly impedes the early and precise dimensioning of operating resources, production areas and employees as well as their cost calculation for planned factories. This also increases the risk of erroneous cost-benefit estimates and potential misinvestments. As a result, an early economic assessment and cost estimate for planned factories is essential. Until now, a holistic approach that can quickly and precisely determine investment costs of different planning variants in an early factory planning phase with only limited and uncertain information is not yet available. In order to close this research gap, a holistic approach for calculating investment costs in an early stage of factory planning is in development within the framework of "ELIAS", a collaborate research project of the Institute of Production Systems and Logistics at Leibniz University Hannover and the GREAN GmbH. The central objective of this research project is the software-based development of an investment cost calculator in order to carry out an economic efficiency assessment for potential factory planning projects at an early stage. This article provides both a brief summary of the need and innovative capability of the research idea and the structured procedure for creating a planning tool that closes the research gap described above. By this means, companies are supported in making future-proof decisions at an early stage despite uncertain and inaccurate data.

description: Due to globally distributed value chains, manufacturing companies are increasingly operating in production networks. The management of these often historically grown networks requires the coordination of many tangible and intangible flows, including the transfer of knowledge between sites. In order to remain competitive in a dynamic market environment, the transfer of in-house production knowledge is essential. In practice, the systematic identification of knowledge transfer needs poses a major challenge for industrial managers, one reason being the high complexity of production networks and thus the large number of knowledge transfer possibilities in the network. However, the transfer of knowledge is always time-consuming and costly. An obstacle is to identify if there is a significant need to initiate a knowledge transfer. For this purpose, it should be examined weather the performance within the production network differs significantly or not. This paper presents an approach to measure performance differences in global production networks to identify knowledge transfer needs. Therefore, a hierarchical performance measurement system, consisting of key performance indicators (KPIs) and focusing on four performance dimensions (quality, time, flexibility, and efficiency), is introduced. Depending on the hierarchical level of the production network (workstation, production system or factory segment), a specific set of KPIs is selected and calculated based on production data acquired by different information systems. In a next step, statistically significant deviations are identified using statistical process control (SPC). Control charts are used to examine the stability and thus to identify knowledge transfer needs. The analytical approach is validated with data from a real industrial case study.

Preliminary data of the stress investigations on aluminum and steel alloys have been obtained by the automatic processing of the interference pattern using a notebook computer. A phase-shift compensation technique in real-time reflection interferometry is used to measure the out-of-plane stress release surface displacement surrounding a small scratch (25 um depth and 0.5 mm width) in a plate with residual stress of around 50 MPa. Comparison between theoretical models for a rectangular and triangular shaped scratch with the experimental data are presented.

description: Today more than ever, companies are forced to regularly initiate projects in their factories in order to ensure competitiveness through constant adaptation and change. Such projects are controlled and managed individually. Implementing many projects frequently leads to situations however, in which different projects overlap regarding their planning and control. Deviation in the projects’ duration and scope further intensifies this effect. To manage environments consisting of projects with different scopes and timelines, companies make use of models for multi-project management (MPM). Due to their aim for general validity, existing models for MPM generally lack a specific focus on the targets and tasks of the factory environment. A new process model is therefore needed to effectively and efficiently plan and control a multi-project environment in the factory. Therefore, the project context and the interdependencies of the model’s tasks shall also be taken into account. In order to build a process model for multi-project management, according to the requirements of the factory, insights from MPM as well as the production environment are needed. In this article an overview of the approach is given and first findings are presented. Based on analogies between models of MPM and production planning and control (PPC), an exemplary excerpt of a combined know-how catalogue is shown, laying the foundation for the further development of a holistic process model.

The interplay between compact and molecular structures in tetraquarks

Publisher: name: arXiv
Year: 2022
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Due to the cluster reducibility of multiquark operators, a strong interplay exists in tetraquarks between the compact structure, resulting from the direct confining forces acting on quarks and gluons, and the molecular structure, dominated by the mesonic clusters. This issue is studied within an effective field theory approach, where the compact tetraquark is treated as an elementary particle. The key ingredient of the analysis is provided by the primary coupling constant of the compact tetraquark to the two mesonic clusters. Under the influence of this coupling, an initially formed compact tetraquark bound state evolves towards a new structure, where a molecular configuration is also present. In the strong-coupling limit, the evolution may end with a shallow bound state of the molecular type. The strong-coupling regime is also favored by the large-$N_c$ properties of QCD. The interplay between compact and molecular structures may provide a natural explanation of the existence of many shallow bound states.

“Buddha-Nature” (Foxing 佛性) in Zhanranʼs (湛然) Adamantine Scalpel Treatise (Jinʼgangpi Lun 金剛錍論),with special focus on its congruence with the Saddharmapundarika (Miaofalianhua Jing 妙法蓮華經) and Mahaparinirvana Sutras (Niepan Jing 涅槃經)

description: Despite the existence of voluminous research on the concept of Buddha-Nature foxing佛性, and the Adamantine Scalpel Treatise or Jin’gangpi-Lun金剛錍論 (c.780A.D.) of Zhanran 湛然 (711–782 A.D.), little attention has been given to the way in which Zhanran’s ‘innovations’ can be interpreted as extensions of, or natural conclusions derived from the Mahāparinirvāṇa (Niepan Jing涅槃經) and Saddharmapuṇḍarīka Sūtras (Miaofalianhua Jing妙法蓮華經). The dominant narrative within scholarly literature contends that Zhanran’s claim for the Buddha-Nature of the insentient, directly conflicts with statements in the Mahāparinirvāṇa, and that Buddha-Nature as term and concept is absent from the Saddharmapuṇḍarīka Sūtra altogether. On the basis of this narrative, it is concluded that Zhanran’s concept of insentient Buddha-Nature is to be traced from exegetical tradition, or non-buddhist sources rather than from these sūtras themselves. Returning to the above scriptures qua primary sources, this study attempts an exegetical reappraisal of Zhanran’s concept of Buddha-Nature, by demonstrating the confluence between these scriptures and Zhanran’s treatise. Via a textual analysis of the two sūtras and Zhanran’s Jin’gangpi, this study endeavours to reveal the intertextual set of meanings Zhanran inherited from earlier Tiantai tradition, and establish not only his consistency with this hermeneutic, but the dialogic relation understood to exist between the two sūtras. By raising questions about the sources underlying Zhanran’s arguments, I respond to the concerns of Buddhists as inheritors of his ideas, and re-examine the conclusions of scholarship by offering an overview of the textual and conceptual parameters in which Zhanran’s ideas must necessarily be viewed. This reassessment contributes to our broader understanding of Chinese intellectual trends, and offers a model for the relation of the thesis and antithesis dichotomy.
Analytical Condition for Synchrony in a Neural Network with Two Periodic Inputs

description: In this study, we apply a mean field theory to the neural network model with two periodic inputs in order to clarify the conditions of synchronies. This mean field theory yields a self-consistent condition for the synchrony and enables us to study the effects of synaptic connections for the behavior of neural networks. Then, we have obtained a condition of synaptic connections for the synchrony with the cycle time $T$. The neurons in neural networks receive sensory inputs and top-down inputs from outside of the network. When the network neurons receive two or more inputs, their synchronization depends on the conditions of inputs. We have also analyzed this case using the mean field theory. As a result, we clarified the following points: (1) The stronger synaptic connections enhance the shorter synchrony cycle of neurons. (2) The cycle of the synchrony becomes longer as the cycle of external inputs becomes longer. (3) The relationships among synaptic weights, the properties of input trains, and the cycle of synchrony are expressed by one equation, and there are two areas for asynchrony. In association with the third point, the yielded equation is so simple for calculation that they can easily provide us feasible and infeasible conditions for synchrony.

description: The self-enrichment scenario for globular clusters (GC) requires large amounts of residual gas after the initial formation of the first stellar generation. Recently, Krause et al. (2012) found that supernovae may not be able to expel that gas, as required to explain their present day gas-free state, and suggested that a sudden accretion on to the dark remnants, at a stage when type II supernovae have ceased, may plausibly lead to fast gas expulsion. Here, we explore the consequences of these results for the self-enrichment scenario via fast rotating massive stars (FRMS). We analyse the interaction of FRMS with the intra-cluster medium (ICM), in particular where, when and how the second generation of stars may form. From the results, we develop a timeline of the first approximately 40 Myr of GC evolution. The results of Paper I imply three phases during which the ICM is in a fundamentally different state, namely the wind bubble phase (lasting 3.5 to 8.8 Myr), the supernova phase (lasting 26.2 to 31.5 Myr), and the dark remnant accretion phase (lasting 0.1 to 4 Myr): (i) Quickly after the first generation massive stars have formed, stellar wind bubbles compress the ICM into thin filaments. No stars may form in the normal way during this phase, due to the high Lyman-Werner flux density. If the first generation massive stars have however equatorial ejections, as we proposed in the FRMS scenario, accretion may resume in the shadow of the equatorial ejecta. The second generation stars may then form due to gravitational instability in these discs that are fed by both the FRMS ejecta and pristine gas. [...]
