description: Bats are considered reservoirs of many lethal zoonotic viruses and have been implicated in several outbreaks of emerging infectious diseases, such as SARS-CoV, MERS-CoV, and SARS-CoV-2. It is necessary to systematically derive the expression patterns of bat virus receptors and their regulatory features for future research into bat-borne viruses and the prediction and prevention of pandemics. Here, we performed single-nucleus RNA sequencing (snRNA-seq) and single-nucleus assay for transposase-accessible chromatin using sequencing (snATAC-seq) of major organ samples collected from Chinese horseshoe bats (Rhinolophus affinis) and systematically checked the expression pattern of bat-related virus receptors and chromatin accessibility across organs and cell types, providing a valuable dataset for studying the nature of infection among bat-borne viruses.

description: For loop integrals, the standard method is reduction. A well-known reduction method for one-loop integrals is the Passarino-Veltman reduction. Inspired by the recent paper [1] where the tadpole reduction coefficients have been solved, in this paper we show the same technique can be used to give a complete integral reduction for any one-loop integrals. The differential operator method is an improved version of the PV-reduction method. Using this method, analytic expressions of all reduction coefficients of the master integrals can be given by algebraic recurrence relation easily. We demonstrate our method explicitly with several examples.

description: We report a non-blocking high-resolution digital delay line based on an asynchronous circuit design. Field programmable gate array logic primitives were used as a source of delay and optimally arranged using combinatorial optimization. This approach allows for an efficient trade-off of the resolution and a delay range together with minimized dead time operation. We demonstrate the method by implementing the delay line adjustable from 23 ns up to 1635 ns with a resolution of 10 ps. We present a detailed experimental characterization of the device focusing on thermal instability, timing jitter, and pulse spreading, which represent three main issues of the asynchronous design. We found a linear dependence of the delay on the temperature with the slope of 0.2 ps/K per a logic primitive. We measured the timing jitter of the delay to be in the range of 7 ps - 165 ps, linearly increasing over the dynamic range of the delay. We reduced the effect of pulse spreading by introducing pulse shrinking circuits, and reached the overall dead time of 4 ns - 22.5 ns within the dynamic range of the delay. The presented non-blocking delay line finds usage in applications where the dead time minimization is crucial, and tens of picoseconds excess jitter is acceptable, such as in many advanced photonic networks.

description: Hierarchy and centrality are two popular notions used to characterize the importance of entities in complex systems. Indeed, many complex systems exhibit a natural hierarchical structure, and centrality is a fundamental characteristic allowing to identify key constituents. Several measures based on various aspects of network topology have been proposed in order to quantify these concepts. While numerous studies have investigated whether centrality measures convey redundant information, how centrality and hierarchy measures are related is still an open issue. In this paper, we investigate the interaction between centrality and hierarchy using several correlation and similarity evaluation measures. A series of experiments is performed in order to evaluate the combinations of 6 centrality measures with 4 hierarchy measures across 28 diverse real-world networks with varying topological characteristics. Results show that network density and transitivity play a key role in shaping the pattern of relations between centrality and hierarchy measures.

description: To evaluate the effect of gamma irradiations on morphological and biochemical variations of in vitro shoots, regenerated plants and rhizomes of ginger (Zingiber officinale Rosc.) var. Himgiri. In vitro established shoot cultures were treated with different doses of gamma irradiations (10–100 Gy). Nonirradiated shoots were used as controls. Radio sensitivity of shoots and in vitro growth parameters were recorded. Surviving shoots along with controls were multiplied, rooted and hardened. Irradiation effect on chromosomes was evaluated by comparing with controls. Various morphological and biochemical observations were recorded in regenerated plants and rhizomes and compared to controls. Irradiated shoots showed decline in survival percentage (95% in 10 Gy to 12.33% in 100 Gy) with increase in dose rate after 4 weeks of irradiation. Shoot survival significantly decreased with irradiation dose rate above 20 Gy. Shoot multiplication rate showed an increase from 1:2 in 1st subculture to 1:9 after 5th subculture, in 10 Gy irradiated cultures with 4.5 cm average length of shoots and 8.19 number of leaves after 5th subculture. Average rooting showed an increase from 15.55% after 2nd subculture to 100% after 5th subculture, in 10 Gy irradiated shoots; however, no multiplication and rooting was observed in higher doses. In vitro rooted shoots were subjected to hardening with 100 percent survival in a mixture comprised of soil, cocopeat and FYM. One-year-old hardened plants when observed for morphological variations showed nonsignificant variations in comparison to controls. Rhizomes obtained from 10 Gy irradiated plants showed enhanced concentration of 6-gingerol and reduced crude fiber content when compared with controls. Gamma irradiation doses up to 10 Gy resulted in nonsignificant phenotypic variations but can positively affect biochemical composition of rhizomes leading to development of biochemically improved mutant lines of ginger with increased 6-gingerol and lowered crude fiber content. Therefore, suggesting the lower doses of gamma irradiations for improvement of biochemical constituents in vegetatively propagated plants.

description: Companies in the manufacturing sector are confronted with an increasingly dynamic environment. Thus, corporate processes and, consequently, the supporting IT landscape must change. This need is not yet fully met in the development of information systems. While best-of-breed approaches are available, monolithic systems that no longer meet the manufacturing industry's requirements are still prevalent in practical use. A modular structure of IT landscapes could combine the advantages of individual and standard information systems and meet the need for adaptability. At present, however, there is no established standard for the modular design of IT landscapes in the field of manufacturing companies' information systems. This paper presents different ways of the modular design of IT landscapes and information systems and analyzes their objects of modularization. For this purpose, a systematic literature research is carried out in the subject area of software and modularization. Starting from the V-model as a reference model, a framework for different levels of modularization was developed by identifying that most scientific approaches carry out modularization at the data structure-based and source code-based levels. Only a few sources address the consideration of modularization at the level of the software environment-based and software function-based level. In particular, no domain-specific application of these levels of modularization, e.g., for manufacturing, was identified.

description: We study the system of two quantum dots lying on the central plane of a planar semiconductor microcavity. By solving the full Maxwell problem, we demonstrate that the rate of resonant excitation transfer between the two dots decays as $d^{-1/2}$ as a function of the distance $d$ at long distance. This very long-range mechanism is due to the leaky and guided modes of the microcavity, which act as effective radiative transfer channels. At short distance, the $d^{-3}$ dependence of the Förster mechanism, induced by the electrostatic dipole-dipole interaction, is recovered.

description: Due to increased data accessibility, data-centric approaches, such as machine learning, are getting more represented in the forming industry to improve resource efficiency and to optimise processes. Prior research shows, that a classification of the roundness of shaped rings, using machine learning algorithms, is applicable to radial-axial ring rolling. The accuracy of these predictions nowadays is still limited by the amount and quality of the data. Therefore, this paper will focus on how to make the best use of the limited amount of data, using transfer learning approaches. Since acquiring data for homogenised databases is time, energy and resource consuming, logged data gathered by the industry is often used in research. This paper takes both, industrial data from thyssenkrupp rothe erde Germany GmbH and a smaller dataset of an inhouse research plant, into account. Additionally, a synthetic dataset, created by generative adversarial networks, is considered. To accomplish an improvement of machine learning predictions using accessible data, three transfer learning approaches are investigated in order to extend existing models: (I) transferring from a radial-axial ring rolling mill to a different mill containing less available data with a ratio of 20:1, (II) learning from unlabelled data using an autoencoder and (III) training on synthetic data. The obtained improvements are further evaluated. Based on these results, future possible investigations are elaborated, in particular the consideration of transfer learning from the less complex cold ring rolling process.

description: The variety of multi-partite entangled states enables numerous applications in novel quantum information tasks. In order to compare the suitability of different states from a theoretical point of view classifications have been introduced. Accordingly, here we derive criteria and demonstrate how to experimentally discriminate an observed state against the ones of certain other classes of multi-partite entangled states. Our method, originating in Bell inequalities, adds an important tool for the characterization of multi-party entanglement.

description: Automation and industrial robots enable today's enterprises to increase productivity. Due to current challenges, such as a shortage of skilled workers, the trend is toward using industrial robots more and more in high-mix low-volume production. For this, enterprises must be able to develop and deploy robotic applications for various products, variants, and tasks easily and quickly. In previous works, we demonstrated the increased flexibility and efficiency of robot programming via a skills-based software framework. In this paper, we expand this framework by considering the overall development and deployment procedure of robotic applications. In addition to modular programming, we address the development of the necessary hardware for the robotic application. Here, we focus on the design of the gripper system. As an exemplary use case we present the handling and testing of variant-rich electronic products. Finally, based on the introduced framework, we show our first implementation results to realize this use case.

description: With only six known examples, M-dwarf debris disks are rare, even though M dwarfs constitute the majority of stars in the Galaxy. After finding a new M dwarf debris disk in a shallow mid-infrared observation of NGC 2547, we present a considerably deeper Spitzer-MIPS image of the region, with a maximum exposure time of 15 minutes per pixel. Among sources selected from a previously published membership list, we identify nine new M dwarfs with excess emission at 24 micron tracing warm material close to the snow line of these stars, at orbital radii of less than 1 AU. We argue that these are likely debris disks, suggesting that planet formation is under way in these systems. Interestingly, the estimated excess fraction of M stars appears to be higher than that of G and K stars in our sample.

description: Quantum field theories are the cornerstones of modern physics, providing relativistic and quantum mechanical descriptions of physical systems at the most fundamental level. Simulating real-time dynamics within these theories remains elusive in classical computing. This provides a unique opportunity for quantum simulators, which hold the promise of revolutionizing our simulation capabilities. Trapped-ion systems are successful quantum-simulator platforms for quantum many-body physics and can operate in digital, or gate-based, and analog modes. Inspired by the progress in proposing and realizing quantum simulations of a number of relativistic quantum field theories using trapped-ion systems, and by the hybrid analog-digital proposals for simulating interacting boson-fermion models, we propose hybrid analog-digital quantum simulations of selected quantum field theories, taking recent developments to the next level. On one hand, the semi-digital nature of this proposal offers more flexibility in engineering generic model interactions compared with a fully-analog approach. On the other hand, encoding the bosonic fields onto the phonon degrees of freedom of the trapped-ion system allows a more efficient usage of simulator resources, and a more natural implementation of intrinsic quantum operations in such platforms. This opens up new ways for simulating complex dynamics of e.g., Abelian and non-Abelian gauge theories, by combining the benefits of digital and analog schemes.

description: Quantum transport properties in quantum Hall wires in the presence of spatially correlated random potential are investigated numerically. It is found that the potential correlation reduces the localization length associated with the edge state, in contrast to the naive expectation that the potential correlation increases it. The effect appears as the sizable shift of quantized conductance plateaus in long wires, where the plateau transitions occur at energies much higher than the Landau band centers. The scale of the shift is of the order of the strength of the random potential and is insensitive to the strength of magnetic fields. Experimental implications are also discussed.

description: Job shop scheduling problems (JSSPs) have been the subject of intense studies for decades because they are often at the core of significant industrial planning challenges and have a high optimization potential. As a result, the scientific community has developed clever heuristics to approximate optimal solutions. A prominent example is the shifting bottleneck heuristic, which iteratively identifies bottlenecks in the current schedule and uses this information to apply targeted optimization steps. In recent years, deep reinforcement learning (DRL) has gained increasing attention for solving scheduling problems in job shops and beyond. One design decision when applying DRL to JSSPs is the observation, i.e., the descriptive representation of the current problem and solution state. Interestingly, DRL solutions do not make use of explicit notions of bottlenecks that have been developed in the past when designing the observation. In this paper, we investigate ways to leverage a definition of bottlenecks inspired by the shifting bottleneck heuristic for JSSPs with DRL to increase the effectiveness and efficiency of model training. To this end, we train two different DRL base models with and without bottleneck features. However, our results indicate that previously developed bottleneck definitions neither increase training efficiency nor final model performance.

description: In the context of sustainable management, organizational resilience is gaining importance. Manufacturing companies are increasingly exposed to external disturbances. At the same time, corporate functions today are usually geared towards efficient execution. A positioning in this trade-off between efficient achievement of goals and the prevention of impacts of disturbances is necessary. Crisis-resistant product development is of particular importance, as innovative products offer a promising opportunity to create competitive advantages and thus secure the company's existence or even enable a company to increase its market share in the event of a crisis. Based on a literature review and its structured consolidation, this paper presents design elements of product development for positioning in this trade-off. The overall dimensions of the design elements are strategy, organization, resources, product, as well as project management. The approach is transferable to other corporate functions.

description: The economic, social and ecological crises of recent years have shown that a change in our understanding of production and value creation is necessary. A more even distribution of production capacities can promote social and economic stability. The ability to produce locally unavailable products or spare parts at short notice (e.g. manufacturing medical-products during the pandemic) avoids CO2 emissions due to transport and increases local production sovereignty and resilience. This means that production structures need to become more dynamic and responsive for spontaneous demand. Increasing local production at the place of need seems to be a solution that addresses the problems raised. When looking at currently available local production structures, small and medium-sized enterprises can be found at most locations. Unfortunately there is still a lack of productivity compared to industrial production in this enterprises. One form of overarching organisation and corporate culture that is largely established as standard in industry is the Lean Business Model. The introduction of such a strategy offers potentials for increasing the productivity and performance of a company regardless of its size. However, the methods and principles are not consistently applied in small and medium-sized enterprises. In the context of this work, studies were identified that deal with the feasibility of implementing Lean Methods in the manufacturing sector worldwide. The results were bundled into a new data model and subjected to a secondary analysis. The aim is to obtain a complete assessment of all lean implementation methods according to VDI2870 Holistic Production Systems. The suitability of the implementability in small and medium-sized enterprises is extended by an evaluation with regard to the target dimensions time, costs and quality. This creates a new possibility for strategic operationalisation of the Lean Methods for manufacturing companies.

description: The crises of recent years revealed the vulnerability of our global and linearly aligned value chains, and new concepts are being sought to meet ecological, economic and social demands. The possibility of producing locally at the place of need in adaptable and highly dynamic manufacturing networks is increasingly coming into focus. However, such structures would have to be built up laboriously, whereas an existing network of small and medium-sized enterprises is available in many industrial nations. Cross-Company Production (CCP) in such local networks could help to address the problems mentioned. Another recent phenomenon is the shift of development processes into the digital sphere and its simultaneous opening up to the public. Open development processes can offer considerable advantages by bundling the wisdom of the crowd across company boundaries, however the digital platforms for collaboration do not have their own product capacities. The interaction of Co-Creation Communities (CCC) and Cross-Company Production (CPP) networks could counter this shortcoming. To ensure cost-efficient production and success on the market, an early exchange of knowledge between development and production is targeted in every company through highly standardised processes in the field of Planning Preparation (PP) a subdivision of Operations Planning and Scheduling (OPS). In the new value creation constellation this exchange is limited, as high fluctuation, various developers and numerous companies involved lead to new challenges. In this approach, a meta synthesis of known innovation and product development processes was performed to gain a better understanding of their structure and to identify measures fulfilling the tasks of Planning Preparation (PP). Aligned with the principles of Cooper's Stage-Gate Process a basis of measures is built up. After that each measure is valued according to relevance and involvement for the introduced entities creating an overview of general measures. Finally, the need for a distributed and agile Planning Preparation (PP) is derived.

In total, more than 1500 ro-torsional HOOD transitions have been assigned between 6 and 120 cm$^{-1}$. We succeeded to analyze the accidental interaction between the torsional sub-states by measuring several perturbed transitions. In addition to the set of Watsonian parameters for each tunneling component, only two interaction constants were required to describe the spectrum. The $K_a$- and $J$-dependance of the torsional splitting could be determined also for the perturbed states.

description: Lithium-ion batteries are seen as a key technology for powering electric vehicles and energy storage. Still, their high cost and energy-intensive manufacturing process remain a significant barrier to wider adoption. Due to the high moisture sensitivity of certain processed materials, the operation of dry rooms is required, constituting a critical contributor to cost and energy consumption in lithium-ion battery production. As the operating costs for these dry rooms strongly depend on the volume and adjusted humidity of the air, it is vital to choose an appropriate operation strategy already in the planning and designing phase of the factories. In this regard, simulation tools can effectively support the planning process by providing predictive information on the production system. The simulation model presented in this paper offers an approach to optimize the material and energy consumption associated with the production of lithium-ion batteries while also considering current material-related production challenges regarding moisture. By calculating a time-resolved material flow, the model enables to identify individual process times and storage durations depending on the chosen production layout. This allows for a material-specific dimensioning of the buffers and supports the dry room design. Hence, the data generated by the model can serve as a basis for planning more cost- and energy-efficient production environments.

description: Chromatin loop extrusion by Structural Maintenance of Chromosome (SMC) complexes is thought to underlie intermediate-scale chromatin organization inside cells. Motivated by a number of experiments suggesting that nucleosomes may block loop extrusion by SMCs, such as cohesin and condensin complexes, we introduce and characterize theoretically a composite loop extrusion factor (composite LEF) model. In addition to an SMC complex that creates a chromatin loop by encircling two threads of DNA, this model includes a remodeling complex that relocates or removes nucleosomes as it progresses along the chromatin, and nucleosomes that block SMC translocation along the DNA. Loop extrusion is enabled by SMC motion along nucleosome-free DNA, created in the wake of the remodeling complex, while nucleosome re-binding behind the SMC acts as a ratchet, holding the SMC close to the remodeling complex. We show that, for a wide range of parameter values, this collection of factors constitutes a composite LEF that extrudes loops with a velocity, comparable to the velocity of remodeling complex translocation on chromatin in the absence of SMC, and much faster than loop extrusion by an isolated SMC that is blocked by nucleosomes.

description: The growing rate of consumption has drawn attention to measurable environmental impacts leading to the development of sustainability tools that can inform environmental, economic and social decisions. Façade glass is a widely used material that is highly recyclable material and is an important material for sustainable assessments as it promotes ideas of Circular Economy if it is done properly after taking into account the quantification of environmental impact associated with recycling activities. Design of sustainable products requires having a lifecycle perspective, including analyzing various End-of-Life (EoL) scenarios. This paper aims to investigate scenarios of when glass is disposed to demonstrate the applicability of glass in a Circular Economy. Life Cycle impact Assessment (LCA) and Circular Economy (CE) literature is critically reviewed to identify progress in research, methodologies employed and areas that require more research which this paper aims to resolve. It was determined recovery, also known as EoL, strategies for glass used in the Australian built environment lacked research despite the growing imperative of sustainable consumption. A typical glazing unit in a facade system was selected for assessment along with three (3) disposal scenarios. Quantifying the environmental impacts are to be interpreted in a LCA along with glass recovery strategies involving recycling, landfill and/or incineration with heat recovery. A CE assessment is performed by interpreting LCA environment impacts associated with the activities required to achieve circularity in a typical apartment in Sydney, Australia. This provides insights supports decision-makers who seek sustainable consumption through ideas of Circular Economy.

description: The present work intends to join and respond to the excellent and thoroughly documented rovibrational study of [X.-G. Wang and T. Carrington, Jr., J. Chem. Phys. 154, 124112 (2021)] that used an approach tailored for floppy dimers with an analytic dimer Hamiltonian and a non-product basis set including Wigner $D$ functions. It is shown in the present work that the GENIUSH black-box-type rovibrational method can approach the performance of the tailor-made computation for the example of the floppy methane-water dimer. Rovibrational transition energies and intensities are obtained in the black-box-type computation with `only' 2-3 times larger basis set sizes and in an excellent numerical agreement in comparison with the more efficient tailor-made approach.

description: High energy resolution photoelectron spectroscopy of conduction electrons in the vicinity of the Fermi-edge in Al and Au at the excitation energy of 880 and 7940 eV was carried out using synchrotron radiation. For the excitation energy of 7940 eV, the observed Fermi energy of Al shows a remarkable shift to higher binding energy as compared with that of Au, with accompanying broadening. This is due to the recoil effect of the emitted photoelectrons. The observed spectra are well reproduced by a simple model of Bloch electrons based on the isotropic Debye model.

description: Furcaperla Cn-G, unassociated female (Fig. 8.) Material examined. 1 female (CAU): China, Guangxi Zhuang Autonomous Region, Fangchenggang City, Shangsi County, Shiwandashan National Forest Park, N 21°54.4’, E 107°54.2’, light trap, 2016. V.26, leg. Xingyue Liu. Description of the female (Fig. 8). Forewing length 17.2 mm, hindwing length 15.1 mm. General color pale brown, but the specimen is teneral. Head pale brown with a dark brown quadrate area in ocellar triangle, triocellate, anterior ocellus inconspicuous. M-line pale with a small dark median spot around anterior ocellus. Head slightly wider than pronotum. Antennae brown to dark brown, pedicel dark brown. Palpi brownish. Pronotum darkest in middle third with distinct rugosities. Subgenital plate short and wide, apically slightly notched; posterior margin with two widely divided groups of long hairs. Posterior margin of sternum 9 slightly produced and arcuate. Remarks. This female from Guangxi Zhuang Autonomous Region can not be identified as any of the above two species. The female subgenital plate is similar to F. bifurcata and F. jiangxiensis but it apparently differs from the latter two by the reduced and inconspicuous anterior ocellus. In F. bifurcata and F. jiangxiensis, anterior ocellus is obvious.

Tra disegno descrittivo convenzionale e disegno d'illustrazione

description: Nella pratica progettuale contemporanea sembra essersi consolidata una sorta di doppia polarità tra due tipi di rappresentazione dell’architettura quella finalizzata alla descrizione dell’edificio in direzione della sua realizzazione (si tratta di disegni altamente convenzionali, articolati in piante, sezioni, prospetti alla scala opportuna) e quella volta alla illustrazione del progetto, generalmente finalizzata alla sua presentazione pubblica (in soprattutto rappresentazione tridimensionale, prospettiva, rendering fotorealistico, fotomontaggio).
Questi due tipi di rappresentazione sembrano ricoprire il territorio del disegno di architettura contemporaneo – e basta guardare il modo in cui nelle riviste e nelle monografie di architettura vengono pubblicati i progetti per trovare conferma a questa osservazione.
Eppure nel lavoro di alcuni architetti contemporanei è possibile ritrovare dei disegni che non sono direttamente riconducibili a una delle due polarità sopra individuate - disegni che tendono a ‘forzarne’ le regole spostando l’attenzione sul processo piuttosto che sul prodotto mostrando in qualche modo il progetto nel suo farsi.
La ricerca intende riconoscere, in questa area ‘indeterminata’ della rappresentazione architettonica, quei tipi di disegno la cui costruzione coincide con una certa fase del processo progettuale: disegni che ‘emergono’ insieme con il progetto, e non ne costituiscono una illustrazione a posteriori, configurandosi come una vera e propria forma di ragionamento.
Il lavoro ha preso il via dalla selezione di una serie di disegni, individuati nella produzione di un numero ristretto di architetti contemporanei, in cui sembrava possibile scorgere quel carattere di ‘sperimentalità’ che li rendeva di non immediata classificazione.
Parallelamente si è iniziato ad indagare il modo in cui il disegno, inteso come pratica progettuale, viene definito nell’ambito della teoria architettonica in modo da registrarne le trasformazioni che più in generale investono la progettazione architettonica.
