description: Componentization is an important, emerging approach to software modernization whereby a stovepipe system is restructured into components that can be reused in other systems.More significantly from the system maintenance perspective, selected components in the original system can be completely replaced, e.g.,the database or user interface. In some cases, a new architecture can be developed, for example to convert a monolithic system to the client/server paradigm, and the old components plugged into place along with some new ones. We update a 1994 publication in this conference series, where we proposed using process modeling and enactment technology to support both construction of systems from components and re-engineering of systems to permit component replacement. This paper describes our experience following that approach through two generations of component-oriented process models.

description: We report the first systematic measurements of the Raman scattering by electrons in elemental metals of Al, Mo, Nb, Os, Pb, Re, Ta, Ti, V, W and metallic compound La$B_6$. Experimental spectra are modelled on the base of the band structures, calculated within the density functional theory, taking properly into account the effects of electron-phonon scattering. The agreement between our measured and calculated spectra is excellent for the variety of metals, thus providing estimates for the electron-phonon coupling constants and temperature-dependent relaxation rates. The method can be applied for other metallic materials to evaluate an electron-phonon coupling as an alternative to the transport and optical measurements.

description: Background and aim: Accurate differentiation of patients with ulcerative colitis (UC) or Crohn’s disease (CD) is important for appropriate therapy and prognosis. This study was designed to explore the utility of proteinase 3 anti-neutrophil cytoplasmic antibodies (PR3-ANCA) in the diagnosis of Chinese patients with inflammatory bowel disease (IBD). Methods: Blood samples were collected from 216 Chinese patients, including 175 IBD and 41 colorectal polyps (disease control). Clinical characteristics were extracted from electronic medical records. Results: Serum PR3-ANCA were increased in UC patients compared to those with CD or colorectal polyps (p < .0001). PR3-ANCA was negative in colorectal polyps and there was no significant difference between CD and colorectal polyps (p > .05). Using the cut-off value of 20 chemiluminescent units (CU) provided by manufacturer, the positive rate of PR3-ANCA was higher in UC than CD (41.7% vs. 1.1%; p < .0001). Receiver operating characteristic (ROC) analysis demonstrated an area under the curve (AUC) of 0.89 (95% CI: 0.84–0.95; p < .0001) for differentiating UC from CD and suggested an optimized cutoff of 7.3 CU which improved sensitivity from 41.7% to 57.1%, while maintaining a specificity of 98.9%. PR3-ANCA in severe UC patients were higher than those with moderate UC (p < .05), no difference was found between those in remission or with mild or moderate activity (p > .05). Conclusions: Serum PR3-ANCA is a potentially useful clinical biomarker in Chinese patients with IBD. A modified cut-off value of 7.3 CU improves the performance for distinguishing UC from CD.

description: Recently announced magnetic models for four SPB and β Cep stars, along with magnetic detections for two additional stars, have potentially doubled the number of known magnetic SPB and βCep stars (see Grunhut et al., these proceedings). We have reanalyzed the published data and re-reduced archival low resolution spectropolarimetry collected with the FORS1/2 instruments at VLT on which the models were based, and compare them with high resolution data from the ESPaDOnS spectropolarimeter at CFHT, investigating previously noted inconsistencies between results from the two instruments.

description: Dla prawidłowego rozwoju psychicznego, emocjonalnego i uczuciowego dziecka konieczna jest jego ciągła więź i osobista relacja z każdym rodzicem. Utrzymywanie jej jest oczywistym prawem dziecka, ale również prawem, i zarazem obowiązkiem, rodziców, wynikającym z przepisów Kodeksu rodzinnego i opiekuńczego. Niestety często zdarza się utrudnianie spotkań rodzica niemieszkającego na co dzień z dzieckiem, przez rodzica, któremu sąd powierzył nad dzieckiem opiekę. W artykule omówione zostały praktyczne aspekty postępowania sankcyjnego przewidzianego w Kodeksie postępowania cywilnego służącego egzekucji prawa do kontaktów z dzieckiem, poprzez nałożenie, jako sankcji, sumy pieniężnej na rodzica, który wbrew dobru dziecka, utrudnia jego spotkania z drugim rodzicem (por. art. 59815–59821 k.p.c.). W trakcie rozważań zostało jednoznacznie podkreślone, że zadaniem sądu jest sankcjonowanie naruszenia nałożonego obowiązku w przedmiocie kontaktów z dzieckiem, nie zaś naruszenia konkretnego orzeczenia sądu regulującego kontakty. Ma to zaś istotny wpływ na niemożliwość umorzenia postępowania sankcyjnego, w przypadku wydania innego orzeczenia stanowiącego podstawę takiego obowiązku.

description: A hypercode software engineering environment represents all plausible multimedia artifacts concerned with software development and evolution that can be placed or generated on-line,from source code to formal documentation to digital library resources to informal email and chat transcripts. A hypercode environment supports both internal (hypertext) and external (link server) links among these artifacts, which can be added incrementally as useful connections are discovered; project-specific hypermedia search and browsing; automated construction of artifacts and hyperlinks according the software process; application of tools to the artifacts according to the process workflow; and collaborative work for geographically dispersed teams. We present a general architecture for what we call hypermedia subwebs, and groupspace services operating on shared subwebs, based on World Wide Web technology which could be applied over the Internet or within an intranet. We describe our realization in OzWeb.

description: Let $T^{ab}=T^{ba}=0$ be a system of differential equations for the components of a metric tensor on $R^m$. Suppose that $T^{ab}$ transforms tensorially under the action of the diffeomorphism group on metrics and that the covariant divergence of $T^{ab}$ vanishes. We then prove that $T^{ab}$ is the Euler-Lagrange expression some Lagrangian density provided that $T^{ab}$ is of third order. Our result extends the classical works of Cartan, Weyl, Vermeil, Lovelock, and Takens on identifying field equations for the metric tensor with the symmetries and conservation laws of the Einstein equations.

description: We discuss the chiral phase diagram in the parameter space of lattice QCD with minimal-doubling fermions, which can be seen as lattice fermions with flavored chemical potential terms. We study strong-coupling lattice QCD with the Karsten-Wilczek formulation, which has one relevant parameter $μ_{3}$ as well as gauge coupling and a mass parameter. We find a nontrivial chiral phase structure with a second-order phase transition between chiral symmetric and broken phases. To capture the whole structure of the phase diagram, we study the related lattice Gross-Neveu model. The result indicates that the chiral phase transition also exists in the weak-coupling region. From these results we speculate on the $μ_{3}$-$g^{2}$ chiral phase diagram in lattice QCD with minimal-doubling fermions, and discuss their application to numerical simulations.

description: We present a method for rapid prototyping of new Bragg ultra-cold atom interferometer (AI) designs useful for assessing the performance of such interferometers. The method simulates the overall effect on the condensate wave function in a given AI design using two separate elements. These are (1) modeling the effect of a Bragg pulse on the wave function and (2) approximating the evolution of the wave function during the intervals between the pulses. The actual sequence of these pulses and intervals is then followed to determine the approximate final wave function from which the interference pattern can be calculated. The exact evolution between pulses is assumed to be governed by the Gross-Pitaevskii (GP) equation whose solution is approximated using a Lagrangian Variational Method to facilitate rapid prototyping. The method presented here is an extension of an earlier one that was used to analyze the results of an experiment [J.E. Simsarian, et al., Phys. Rev. Lett. 83, 2040 (2000)], where the phase of a Bose-Einstein condensate was measured using a Mach- Zehnder-type Bragg AI. We have developed both 1D and 3D versions of this method and we have determined their validity by comparing their predicted interference patterns with those obtained by numerical integration of the 1D GP equation and with the results of the above experiment. We find excellent agreement between the 1D interference patterns predicted by this method and those found by the GP equation. We show that we can reproduce all of the results of that experiment without recourse to an ad hoc velocity-kick correction needed by the earlier method, including some experimental results that the earlier model did not predict. We also found that this method provides estimates of 1D interference patterns at least four orders-of-magnitude faster than direct numerical solution of the 1D GP equation.

description: We introduce new architectural optimizations for asynchronous systems. These optimizations allow application of voltage scaling, to reduce power consumption while maintaining system throughput. In particular, three new asynchronous sequencer designs are introduced, which increase the concurrent activity of the system.We show that existing datapaths will not work correctly at the increased level of concurrency. To insure correct operation, modified latch and multiplexer designs are presented, for both dual-rail and single-rail implementations. The increased concurrency allows the opportunity for substantial system-wide power savings through application of voltage scaling.

description: We obtain a query lower bound for quantum algorithms solving the phase estimation problem. Our analysis generalizes existing lower bound approaches to the case where the oracle Q is given by controlled powers Q^p of Q, as it is for example in Shor's order finding algorithm. In this setting we will prove a log (1/epsilon) lower bound for the number of applications of Q^p1, Q^p2, ... This bound is tight due to a matching upper bound. We obtain the lower bound using a new technique based on frequency analysis.

description: We investigate the validity of the generalized second law (GSL) of gravitational thermodynamics in the framework of f(T) modified teleparallel gravity. We consider a spatially flat FRW universe containing only the pressureless matter. The boundary of the universe is assumed to be enclosed by the Hubble horizon. For two viable f(T) models containing $f(T)=T+μ_1{(-T)}^n$ and $f(T)=T-μ_2 T(1-e^{β\frac{T_0}{T}})$, we first calculate the effective equation of state and deceleration parameters. Then, we investigate the null and strong energy conditions and conclude that a sudden future singularity appears in both models. Furthermore, using a cosmographic analysis we check the viability of two models. Finally, we examine the validity of the GSL and find that for both models it is satisfied from the early times to the present epoch. But in the future, the GSL is violated for the special ranges of the torsion scalar T.

description: The driving force of the dynamical system can be decomposed into the gradient of a potential landscape and curl flux (current). The fluctuation-dissipation theorem (FDT) is often applied to near equilibrium systems with detailed balance. The response due to a small perturbation can be expressed by a spontaneous fluctuation. For non-equilibrium systems, we derived a generalized FDT that the response function is composed of two parts: (1) a spontaneous correlation representing the relaxation which is present in the near equilibrium systems with detailed balance; (2) a correlation related to the persistence of the curl flux in steady state, which is also in part linked to a internal curvature of a gauge field. The generalized FDT is also related to the fluctuation theorem. In the equal time limit, the generalized FDT naturally leads to non-equilibrium thermodynamics where the entropy production rate can be decomposed into spontaneous relaxation driven by gradient force and house keeping contribution driven by the non-zero flux that sustains the non-equilibrium environment and breaks the detailed balance.

description: This study aims to provide a comprehensive summary of the inactivation of airborne Escherichia coli [(E. coli), a gram-negative bacterium], Bacillus subtilis [(B. subtilis), a gram-positive bacterium], MS2 (a bacteriophage) virus, and Aspergillus versicolor [(A. versicolor), a fungus] with kinetic analysis utilizing microwave irradiation based on absorption material. The capacity of a microwave-absorbing material Fe3O4@SiC ceramic foam (Fe3O4@SiCcf) to inactivate bioaerosols when subjected to microwave (MW) irradiation (2450 MHz) for 25 seconds at various output powers (750, 550, 350, and 150 W) was determined. The airborne MS2 decreased by 4.5 logs at the microwave (MW) input energy density of 7.2 × 103 kJ/m3, while that for E. coli was at around 4.4 logs, and that for B. subtilis was at 4.3 logs. The activation energy (Ea) applied was 13.2 kJ/mol (E. coli), 14.6 kJ/mol (B. subtilis), and that for MS2 virus was 9.6 kJ/mol. By contrast, this study has shown that A. versicolor log inactivation efficiency was lower and Ea was higher than others, which were 3.6 logs and 16.7 kJ/mol, respectively. In addition, MW - Fe3O4@SiCcf improved the inactivation efficiency of airborne microorganisms significantly compared with no absorbing material. Through the comparative analysis of energy consumption, the rate of constant airborne inactivation through MW irradiation is higher than UV and Fenton. However, the energy efficacy per MW irradiation order is lower. In summary, Fe3O4@SiCcf ceramic form is an energy-efficient material for inactivating airborne microorganisms under MW irradiation.

description: Pricing is one of the most important, but underestimated tools, to enhance a company's profitability. Especially in the furniture sector, customers place a special interest in cost-efficient products and easy processes. Individualised and sustainable furniture can help to create a unique selling point and deliver real value to the customers. Therefore, a platform to create designs together is needed and can involve several stakeholders in the design and production phase. However, in order to include several stakeholders, the pricing and revenue model need to reflect individual needs and be a benefit to all. In this paper, the initial situation and potential revenue model options will be presented. Furthermore, multiple scenarios for practical use will be discovered and an overview given.

description: Rapid improvements in network bandwidth, cost, and ubiquity combined with the security hazards and high total cost of ownership of personal computers have created a growing market for thin-client computing. We introduce THINC, a remote display system architecture for high-performance thin-client computing in both LAN and WAN environments. THINC transparently maps high-level application display calls to a few simple low-level commands which can be implemented easily and efficiently. THINC introduces a number of novel latency-sensitive optimization techniques, including offscreen drawing awareness, command buffering and scheduling, non-blocking display operation, native video support, and server-side screen scaling. We have implemented THINC in an XFree86/Linux environment and compared its performance with other popular approaches, including Citrix MetaFrame, Microsoft Terminal Services, SunRay, VNC, and X. Our experimental results on web and video applications demonstrate that THINC can be as much as five times faster than traditional thin-client systems in high latency network environments and is capable of playing full-screen video at full frame rate.

description: Electric field is a thermodynamic force that can drive collisional inter-ion-species transport in a multicomponent plasma. In an inertial confinement fusion (ICF) capsule, such transport causes fuel ion separation even with a target initially prepared to have equal number densities for the two fuel ion species. Unlike the baro-diffusion driven by ion pressure gradient and the thermo-diffusion driven by ion and electron temperature gradients, electro-diffusion has a critical dependence on the charge-to-mass ratio of the ion species. Specifically, it is shown here that electro-diffusion vanishes if the ion species have the same charge-to-mass ratio. An explicit expression for the electro-diffusion ratio is obtained and used to investigate the relative importance of electro- and baro-diffusion mechanisms. In particular, it is found that electro-diffusion reinforces baro-diffusion in the deuterium and tritium mix, but tends to cancel it in the deuterium and helium-3 mix.

description: This paper develops goodness of fit statistics that can be used to formally assess Markov random field models for spatial data, when the model distributions are discrete or continuous and potentially parametric. Test statistics are formed from generalized spatial residuals which are collected over groups of nonneighboring spatial observations, called concliques. Under a hypothesized Markov model structure, spatial residuals within each conclique are shown to be independent and identically distributed as uniform variables. The information from a series of concliques can be then pooled into goodness of fit statistics. Under some conditions, large sample distributions of these statistics are explicitly derived for testing both simple and composite hypotheses, where the latter involves additional parametric estimation steps. The distributional results are verified through simulation, and a data example illustrates the method for model assessment.

description: The quarrying industry, which largely consists of less digitized SMEs, is an integral part of the German economy. More than 95% of the primary raw materials produced are used by the domestic construction industry. Quarrying companies operate demand-oriented with short planning horizons at several locations simultaneously. Due to the low level of digitization and the reluctance to share data, untapped efficiency potential in data-based demand forecasting and capacity planning arises. The situation is aggravated by the fact that SMEs have a heterogeneous mobile machinery so as not to become dependent on individual suppliers, and that transport distances of over 50 kilometers are uneconomical due to high transport costs and low material values. Within the research project PROmining a data-centric platform which improves demand forecast accuracy and multi-site capacity utilization is developed. One of the core functionalities of this platform is an industry-specific demand forecasting model. Against this background, this paper presents a methodology for establishing this forecasting model. To this end, expected demands of secondary industry sectors will be analyzed to improve mid-term volume-forecasting accuracy for the local quarrying industry. The data-centric platform will connect demand forecasting data with relevant key performance indicators of multi-site asset utilization. Following this methodology, operational planning horizons can be extended while significantly improving overall production efficiency. Thus, quarrying businesses are enabled to respond to fluctuating demand volumes effectively and can increase their personnel and machine utilization across multiple quarry sites.

description: The asymmetric intermolecular Heck reaction should prove to be very useful in organic synthesis, as the Heck reaction itself is a carbon-carbon bond-forming reaction, and tolerates a variety of functional groups. To make such an intermolecular reaction asymmetric would eliminate the need for classical resolution techniques, and a variety of achiral substrates could be combined to make chiral products. Much synthetic work has been devoted to the preparation of novel chiral ligands for the asymmetric intermolecular Heck reaction between 2,3-dihydrofuran and a variety of aryl triflates. A wide variety in the regioselectivity and enantioselectivity of the reaction has been seen, due to the use of different palladium sources, ligands, bases, solvents, and temperatures. Some researchers have proposed mechanisms to account for the asymmetric intermolecular Heck reaction, but these mechanisms are found to be contradictory in some respects. One set of Heck reaction conditions has been selected, and the mechanism of the Heck reaction under those conditions has been investigated more thoroughly, through the use of deuterium labelling, time studies, and NMR studies. Four deuterated dihydrofurans have been synthesized, each requiring a different synthetic pathway to be developed. The products from the Heck reaction with each of the four deuterated dihydrofurans have been characterized. Based on the structures of the products, it is possible to deduce the mechanisms of their formation under the Heck reaction conditions. Once the mechanism of product formation was known, the Heck reaction has been followed over time, to monitor the enantiopurity of the products. One of the products of the Heck reaction has been found capable of binding to the palladium (0) catalyst, causing an alteration in the ligand set around the metal, and thereby affecting the regioselectivity and enantioselectivity of the reaction. The results of all these studies are thought to be consistent with the data found in the literature, and give a more complete understanding of the mechanism of the asymmetric Heck reaction.

description: A quasi-linear theory is presented for how randomly forced, barotropic velocity fluctuations cause an exponentially-growing, large-scale (mean) magnetic dynamo in the presence of a uniform shear flow, $\vec{U} = S x \vec{e}_y$. It is a "kinematic" theory for the growth of the mean magnetic energy from a small initial seed, neglecting the saturation effects of the Lorentz force. The quasi-linear approximation is most broadly justifiable by its correspondence with computational solutions of nonlinear magneto-hydrodynamics, and it is rigorously derived in the limit of large resistivity, $η\rightarrow \infty$. Dynamo action occurs even without mean helicity in the forcing or flow, but random helicity variance is then essential. In a sufficiently large domain and with small wavenumber $k_z$ in the direction perpendicular to the mean shearing plane, a positive exponential growth rate $γ$ can occur for arbitrary values of $η$, the viscosity $ν$, and the random-forcing correlation time $t_f$ and phase angle $θ_f$ in the shearing plane. The value of $γ$ is independent of the domain size. The shear dynamo is "fast", with finite $γ> 0$ in the limit of $η\rightarrow 0$. Averaged over the random forcing ensemble, the mean magnetic field grows more slowly, if at all, compared to the r.m.s. field (or magnetic energy). In the limit of small Reynolds numbers ($η, \ ν\rightarrow \infty$), the dynamo behavior is related to the well-known alpha--omega {\it ansatz} when the forcing is steady ($t_f \rightarrow \infty$) and to the "incoherent" alpha--omega {\it ansatz} when the forcing is purely fluctuating.

description: The European Commission set out the goal of carbon neutrality by 2050, which shall be achieved by fostering the twin transition - sustainability through digitalization. A keystone in this transition is the implementation of a prospering Circular Economy (CE). However, product information required to establish a flourishing CE is hardly available or even accessible. The Digital Product Passport (DPP) offers a solution to that problem but in the current discussion, two separate topics are focused on: its architecture and its application on batteries. The content of the DPP has not been an essential part of the discussion, although access to high-quality data about a product's state, composition and ecological footprint is required to enable sustainable decision-making. Therefore, this paper presents a classification of product data for circularity in the manufacturing industry to emphasize the discussion about the DPP's content. Developed through a systematic literature review combined with a case-study-research based on common operational information systems, the classification comprises three levels with 62 data points in four main categories: (1) Product information, (2) Utilization information, (3) Value chain information and (4) Sustainability information. In this paper, the potential content structure of a DPP is demonstrated for a use case in the machinery sector. The contribution to the science and operations community is twofold: Building a guideline for DPP developers that require scientific input from available real-world data points as well as motivating manufacturers to share the presented data points enabling a circular product information management.

description: The continuously increasing amount of production data and the advancing development of digitization solutions promote advanced data analytics as a promising approach for failure management. Beyond the consideration of single units, examining the end-to-end value chain, including development, production, and usage, offers potential for failure in management-related investigations. Nonetheless, challenges regarding data integration from different entities along the value creation process, data volume and formats handling, effective analytics, and decision support arise. The CRISP-DM approach has become a widely established reference as a conceptual framework for data-driven solutions. However, the linkage between existing failure management procedures and the subsequent development of data-driven solutions needs to be specified. Accordingly, this paper presents a cross-value chain Data Enabled Failure Management Process (DEFMP). The central element is a process model to implement a cross-value chain data-enabled failure management, considering established quality management and data analytics approaches. Based on available failure, product, and process knowledge along the value chain, a path towards developing a comprehensive decision support system is shown. DEFMP combines a reactive failure process with a data-driven approach to incorporate data analytics for proactive improvements. Using DEFMP, the failure management process of a commercial vehicle manufacturer is adapted. With this, partial automation of failure management is made possible. In addition, the potential for improvements is identified and prioritized.

description: The growth rate of solar activity in the early phase of a solar cycle has been known to be well correlated with the subsequent amplitude (solar maximum). It provides very useful information for a new solar cycle as its variation reflects the temporal evolution of the dynamic process of solar magnetic activities from the initial phase to the peak phase of the cycle. The correlation coefficient between the solar maximum (Rmax) and the rising rate (βa) at Δm months after the solar minimum (Rmin) is studied and shown to increase as the cycle progresses with an inflection point (r = 0.83) at about Δm = 20 months. The prediction error of Rmax based on βa is found within estimation at the 90% level of confidence and the relative prediction error will be less than 20% when Δm \geq 20. From the above relationship, the current cycle (24) is preliminarily predicted to peak around October 2013 with a size of Rmax =84 \pm 33 at the 90% level of confidence.
