description: We consider an epidemiological SIR model with an infection rate depending on the recovered population. We establish sufficient conditions for existence, uniqueness, and stability (local and global) of endemic equilibria and consider also the stability of the disease-free equilibrium. We show that, in contrast with classical SIR models, a system with a recovery-dependent infection rate can have multiple endemic stable equilibria (multistability) and multiple stable and unstable saddle points of equilibria. We establish conditions for the occurrence of these phenomena and illustrate the results with some examples.

description: The purpose of this study is to estimate elasticities of substitution for apples imported from US, New Zealand and Chile. The study also tested the impact of NAFTA on the apple trade using trade data from 1988 to 2004. The assumptions of Armington model are used to model trade flow of apples employing Linear Approximate of Almost Ideal Demand System. NAFTA has a significant affect on the exporters' share of Canadian import market. Further, New Zealand is emerging one of the strong exporters of apples to Canada by gaining most of the share lost by other countries. Import demand of apples in the case of New Zealand and Chile are elastic while just above unit elastic in case of US. Apples imported from New Zealand were complements to those imported from Chile. The elasticities of substitution of New Zealand and Chile are statistically significant and slightly elastic while that of US is insignificant and inelastic. The rest of the world has elastic elasticities of substitution mainly due to the low share in Canadian imports of apples. Homotheticity could not be rejected that has important implications for international trade and CGE modeling. However, more evidence on testing of the Armington assumptions in trade flow investigations of fruits and vegetables are required.

description: Paper accepted in the Foundation Track of ACM/IEEE 24th International Conference on Model Driven Engineering Languages and Systems (MODELS), 2021. Architectural design decisions, such as service deployment and composition, plant layout synthesis, or production planning, are an indispensable and overarching part of an industrial manufacturing system design. In the fourth industrial revolution (Industry 4.0), frequent production changes trigger their synthesis, and preferably optimization. Yet, knowledge on architecture synthesis and optimization has been scattered around other domains, such as generic software engineering. We take a step towards synthesizing current knowledge on architectural design decisions in Industry 4.0. We developed a taxonomy describing architectural models, design decisions, and optimization possibilities. The developed taxonomy serves as a guideline for comparing different possibilities (e.g., application of different optimization algorithms) and selecting appropriate ones for a given context. Furthermore, we reviewed and mapped 30 relevant research works to the taxonomy, identifying research trends and gaps. We discuss interesting, and yet uncovered topics that emerged from our review.

description: The dynamics of light in Fabry-Perot cavities with varying length and input laser frequency are analyzed and the exact condition for resonance is derived. This dynamic resonance depends on the light transit time in the cavity and the Doppler effect due to the mirror motions. The response of the cavity to length variations is very different from its response to laser frequency variations. If the frequency of these variations is equal to multiples of the cavity free spectral range, the response to length is maximized while the response to the laser frequency is zero. Implications of these results for the detection of gravitational waves using kilometer-scale Fabry-Perot cavities are discussed.

description: Shared Mobility-on-Demand using automated vehicles can reduce energy consumption and cost for future mobility. However, its full potential in energy saving has not been fully explored. An algorithm to minimize fleet fuel consumption while satisfying customers travel time constraints is developed in this paper. Numerical simulations with realistic travel demand and route choice are performed, showing that if fuel consumption is not considered, the MOD service can increase fleet fuel consumption due to increased empty vehicle mileage. With fuel consumption as part of the cost function, we can reduce total fuel consumption by 7 percent while maintaining a high level of mobility service.

The spectral energy distribution of self-gravitating protostellar disks

Year: 2001

description: The long wavelength emission of protostellar objects is commonly attributed to a disk of gas and dust around the central protostar. In the first stages of disk accretion or in the case of high mass protostars, the disk mass is likely to be sufficiently large, so that the disk self-gravity may have an impact on the dynamics and the emission properties of the disk. In this paper we describe the spectral energy distribution (SED) produced by a simple, non-flaring, self-gravitating accretion disk model. Self-gravity is included in the calculation of the rotation curve of the disk and in the energy balance equation, as a term of effective heating related to Jeans instability. In order to quantify in detail the requirements on the mass of the disk and on the accretion rate posed on the models by realistic situations, we compare the SEDs produced by these models with the observed SEDs of a small sample of well-studied protostellar objects. We find that relatively modest disks - even lighter than the central star - can lead to an interesting fit to the infrared SED of the FU Orionis objects considered, while in the case of T Tauri stars the required parameters fall outside the range suggested as acceptable by the general theoretical and observational scenario. On the basis of the present results, we may conclude that the contribution of a self-gravitating disk is plausible in several cases (in particular, for FU Orionis objects) and that, in the standard irradiation dominated disk scenario, it would help softening the requirements encountered by Keplerian accretion models.

description: We examine how the behavior of software developers changes in response to removing gamification elements from GitHub, an online platform for collaborative programming. We find that the unannounced removal of daily activity streak counters from the user profile pages was followed by significant changes in behavior. Long-running streaks of activity were abandoned and became less common. Weekend activity decreased and days in which developers made a single contribution became less common. Synchronization of streaking behavior in the platform’s social network also decreased, suggesting that gamification is a powerful channel for social influence. Software developers that were publicly pursuing a goal to make contributions for 100 days in a row abandon this quest following the removal of the streak counter. Our findings provide evidence for the significant impact of gamification on the behavior of developers. They urge caution: gamification can steer the behavior in unexpected and unwanted directions.

description: The issue of widening regional disparities is a growing concern for balanced development across the states as a development strategy. But, the balanced agricultural development is retarded due to wide regional disparity. In view of this, the study has attempted to measure the spatio-temporal disparities by constructing the composite agricultural development index (CADI) of the 17 major states and all India by assigning different weights to the indicators of agricultural development. This study also attempts to classify states according to their status of agricultural development. Wide disparities in the level of agricultural development had been observed across the states. But the coefficient of variation showed the declining trend indicating a convergent trend in the inter-state levels of agricultural development and narrowing down the disparities level across the states. Most of the states progressed between the early period of Green Revolution (1971-72) and the period of post Green Revolution (1985-86). It was observed that the states had changed their relative rank and absolute indices but holding the same category all the period except Assam, Jammu and Kashmir and Maharastra. The large imbalances exist in the agricultural development indicators across the states, which is the barrier for accentuating balanced development. Thus, for minimizing the inter-state disparities and to promote the balanced agricultural development, the resources should be distributed on the basis of equity, efficiency, productivity and sustainability.

description:
Sand, shaping both natural waterways and urban infrastructure, has recently seen a major surge in extraction, particularly in rapidly urbanizing regions like West Africa. To assess the organization, quantification, and socio-ecological implications of sand mining around Mali’s capital Bamako, we employed a mixed methods approach including structured and unstructured interviews, truck counts, turbidity analyses, and river depth measurements. Our study identified five artisanal systems for mining sand and gravel from the Niger River, using tied-up pirogues, single pirogues, carts, tractors, and trucks. Recent increases in extracted quantities, workforce size, and sand prices were observed, resulting in an estimated annual extraction of 4.86 million m³ in 2022, mainly sourced from upstream of Bamako. With extraction rates surpassing natural replenishment, the riverbed in the study communities of Gouni and Usine Toch has reportedly lowered by 1.4 m and 1.8 m during the last 50 years. Mining activities are highly informal, characterized by self-organization, low and irregular salaries, and unsafe working conditions, particularly for women. Economically, sand mining activities have created symbiotic relationships rather than conflicts with local farming, fishing and other livelihoods. Sand mining operations did not significantly affect the Niger River’s water turbidity, which varied primarily with seasonal rainfall fluctuations. Recent developments suggest that mining activities are accelerating, with mechanized practices likely to replace current artisanal methods and underlying social structures.

DNA-Schadensantwort

description: Die Poly(ADP-Ribose)-Polymerase 1 (PARP1) spielt eine multifunktionale Rolle in der DNA-Schadensantwort (DDR) und gilt als Schlüsselprotein für die Aufrechterhaltung der genomischen Stabilität. Nach Exposition mit ionisierender Strahlung (IR) wurde bereits gezeigt, dass PARP1 mit mehreren zentralen Signalproteinen der DDR interagiert und einen direkten Einfluss auf die p53-vermittelte Schadensreaktion zu nehmen scheint. Die Reichweite der PARP1-vermittelten Antwort, und inwieweit die Interaktionen grundlegend für die Schadensantwort sind, sind jedoch noch nicht geklärt. Diese Arbeit soll dazu beitragen, die multifunktionale Rolle von PARP1 im Signalnetzwerk der DDR besser einordnen zu können. Im Rahmen der vorliegenden Arbeit wurde mittels CRISPR/Cas9 eine U2OS-basierte PARP1-Knockout Zelllinie generiert, die anschließend dazu diente, die Rolle von PARP1 in der DDR zu untersuchen. Durchgeführt wurden Vergleichsuntersuchungen der U2OS Wildtyp Zelllinie und der U2OS PARP1-Knockout Zelllinie unter basalen Bedingungen sowie unter Einfluss verschiedener Schadensarten. Genexpressionsanalysen sowie die Analyse der Zellzyklusverteilung nach Behandlung mit ionisierender Strahlung offenbarten deutliche Unterschiede in der DNA-Schadensantwort, die eine neue potenzielle Verbindung zwischen den Signalwegen von dem Sensorprotein PARP1, dem Transducer-Protein ATM und p53, einer der wichtigsten Effektorproteine in der DDR, aufzeigte. Es konnte ferner gezeigt werden, dass PARP1 einen größeren Einfluss auf die transkriptionelle Aktivität von p53 hat als bisher angenommen. Der Grund hierfür lässt sich auf Signalwege upstream von p53 zurückführen, die sich unter anderem auf die Interaktion von PARP1 mit ATM zurückführen lassen. Des Weiteren konnte festgestellt werden, dass eine fehlende Funktion von PARP1 einen permanenten G2-Arrest nach Schadensinduktion verursacht und den Zelltod der geschädigten Zellen maßgeblich beeinträchtigt. Letzteres lässt sich ebenfalls auf die durch PARP1 vermittelte p53-Aktivität zurückführen und darüber hinaus vermutlich auf den PARP1-abhängigen Zelltodmechanismus Parthanatos. Das Zusammenwirken von PARP1 und ATM scheint wesentlich beim Ablauf der DDR nach IR zu sein und beeinflusst hierbei die p53-abhängige Schadensantwort auf unterschiedlichen Ebenen. PARP1 spielt folglich eine wesentliche Rolle für eine funktionierende Schadensantwort nach ionisierender Strahlung. Der Einfluss von PARP1 auf ATM konnte in dieser Arbeit jedoch nicht auf funktioneller Ebene spezifiziert werden, sodass weitere Studien erforderlich sind, um die Interaktion von PARP1 und ATM im Kontext der DDR zu verifizieren.

description: Our scoping review extends the work of Evans et al. (2024) to specifically search and map the literature on ways in which trust is systematically measured in AI-based CDSS that predict clinical deterioration. We use clinical deterioration to refer to, or be used synonymously with, in-hospital or acute patient deterioration and to describe when a patient’s condition worsens resulting in increased risk of morbidity or mortality.21 In addition to this conceptual approach, we employ discrete clinical complications including sepsis, acute kidney injury (AKI), acute liver failure, cardiac arrest, respiratory failure, and shock when defining clinical deterioration.

The objective of this scoping review is to summarize the literature related to assessing and/or measuring trust in AI-based CDSSs that predict deterioration. We will categorize the articles on different ways the trust has been assessed or measured with regard to AI-based CDSS that predict deterioration and identify gaps/opportunities for future research.

description: This work has been published as a full paper at SEAMS'21. In the context of self-adaptive systems, there are situations where human involvement in the adaptation process is beneficial or even necessary. For such ''human-in-the-loop'' adaptive systems, two major challenges, namely transparency, and controllability must be addressed to include the human in the self-adaptation loop. Transparency covers the context information about the adaptive system and its context while controllability targets the decision-making and adaptation operations. As existing human-in-the-loop adaptation approaches do not fully cover these aspects, we investigate alternative human-in-the-loop strategies by using a combination of digital twins and virtual reality (VR) interfaces. Based on the concept of the digital twin, we represent a self-adaptive system and its respective context in a virtual environment. For integrating the human in the decision-making and adaptation process, we have implemented and analyzed two different human-in-the-loop strategies in VR: a procedural control where the human can control the decision making-process and adaptations through VR interactions and a declarative control where the human specifies the goal state and the configuration is delegated to an AI planner. We evaluate our approach based on an autonomic robot system that is accessible through a VR interface.

description: The study attempted to examine the marketing system of fish seed aiming to determine the channel and marketing profit of market participants. For this study 20 hatchery operators, 80 nurserers, 20 fry traders and 90 pond fish farmers were selected from four districts of Bangladesh. Primary data were collected by survey method wherein various market participants were interviewed from the selected areas for eliciting information at various stages of fish seed marketing. Hatchery operator sells fish seed at their farm gate to nurserers and fry traders. In general, fish farmers receive fish seed from fry traders at their farms. For that reason, both hatchery operators and fish farmers had no marketing cost. The fry traders and r}urserers - the main intermediaries or market participants incurred marketing cost as they performed different marketing functions. Purchase and sale price were main determinants in making profit for market participants. The study revealed that government fish seed farms (GFSFs) produced good quality fish seed and accordingly their cost of production and sales price both were higher compared to private fish seed farms (PFSFs). As a result. marketing margin and profit for market participants who purchased seeds from GFSFs were also higher compared to those who purchased seeds from PFSFs. The seasonal price variation was observed in different months of a year due to changes in demand and supply of fish seed.

description: We present a novel method of robust probabilistic cosmic web particle classification in three dimensions using a supervised machine learning algorithm. Training data was generated using a simplified $Λ$CDM toy model with pre-determined algorithms for generating halos, filaments, and voids. While this framework is not constrained by physical modeling, it can be generated substantially more quickly than an N-body simulation without loss in classification accuracy. For each particle in this dataset, measurements were taken of the local density field magnitude and directionality. These measurements were used to train a random forest algorithm, which was used to assign class probabilities to each particle in a $Λ$CDM, dark matter-only N-body simulation with $256^3$ particles, as well as on another toy model data set. By comparing the trends in the ROC curves and other statistical metrics of the classes assigned to particles in each dataset using different feature sets, we demonstrate that the combination of measurements of the local density field magnitude and directionality enables accurate and consistent classification of halo, filament, and void particles in varied environments We also show that this combination of training features ensures that the construction of our toy model does not affect classification. The use of a fully supervised algorithm allows greater control over the information deemed important for classification, preventing issues arising from hyperparameters and mode collapse in deep learning models. Due to the speed of training data generation, our method is highly scalable, making it particularly suited for classifying large datasets, including observed data.

description: Millimeter wave (MmWave) communications is capable of supporting multi-gigabit wireless access thanks to its abundant spectrum resource. However, the severe path loss and high directivity make it vulnerable to blockage events, which can be frequent in indoor and dense urban environments. To address this issue, in this paper, we introduce intelligent reflecting surface (IRS) as a new technology to provide effective reflected paths to enhance coverage of mmWave signals. In this framework, we study joint active and passive precoding design for IRS-assisted mmWave systems, where multiple IRSs are deployed to assist the data transmission from a base station (BS) to a single-antenna receiver. Our objective is to maximize the received signal power by jointly optimizing the transmit precoding vector at the BS and the phase shift parameters used by IRSs for passive beamforming. Although such an optimization problem is generally non-convex, we show that, by exploiting some important characteristics of mmWave channels, an optimal closed-form solution can be derived for the single IRS case and a near-optimal analytical solution can be obtained for the multi-IRS case. Our analysis reveals that the received signal power increases quadratically with the number of reflecting elements for both the single IRS and multi-IRS cases. Simulation results are included to verify the optimality and near-optimality of our proposed solutions. Results also show that IRSs can help create effective virtual LOS paths and thus substantially improve robustness against blockages in mmWave communications.

description: We derive a quantum state of the disoriented chiral condensate dynamically, considering small quantum fluctuations around a classical chiral condensate disoriented in a certain direction $ \vec n $ in isospace. The obtained nonisosinglet quantum state has the characteristic features; (i) it has the form of the squeezed state, (ii) the state contains not only the component of pion quanta in the direction $ \vec n $ but also the component in the perpendicular direction to $ \vec n $ and (iii) the low momentum pions in the state violate the isospin symmetry. With the quantum state, we calculate the probability of the neutral fraction depending on the time and the pion's momentum, and find that the probability has an unfamiliar form. For the low momentum pions, the parametric resonance mechanism works with the result that the probability of the neutral fraction becomes the well known form approximately and that the charge fluctuation is small.

description: Software development processes are very diverse, and the use of methods and practices varies in many facets. However, it is unclear for what reason single methods and practices are included in a development process and which phases they are meant to support. Based on a survey with 27 practitioners, we provide a mapping of methods and practices to different project phases and vice versa. Our results indicate that, when devising a development process, it is worth a thought if all phases of the software lifecycle are addressed and if the use of selected methods and practices is meaningful. This summary refers to the paper ''Towards Shaping the Software Lifecycle with Methods and Practices''. This paper was published as full research paper in the proceedings of the Joint International Conference on Software and System Processes and International Conference on Global Software Engineering and received the IEEE Best Industry Experience Paper Award.

description: We consider a triangle diagram for $B^0\to (J/ψπ^+π^-) K^+π^-$ where an $X(3872)$ peak has been observed experimentally. We demonstrate that a triangle singularity inherent in the triangle diagram creates a sharp peak in the $J/ψπ^+π^-$ invariant mass distribution when the final $(J/ψπ^+π^-)π$ invariant mass is at and around the $D^*\bar D^*$ threshold. The position and width of the peak is 3871.68 MeV (a few keV above the $D^{*0}\bar{D}^0$ threshold) and $\sim$0.4 MeV, respectively, in perfect agreement with the precisely measured $X(3872)$ mass and width: $3871.69\pm 0.17$ MeV and $< 1.2$ MeV. This remarkable agreement is virtually parameter-free. The result indicates that the considered mechanism has to be understood in advance when separating an $X(3872)$-pole contribution from $B^0\to (J/ψπ^+π^-) K^+π^-$ data; the separation yields an $X(3872)π$ lineshape that could be used to determine the $X(3872)$ mass. We suggest a method to set a constraint on the triangle mechanism by analyzing a charge analogous process $B^0\to (J/ψπ^0π^-) K^+π^0$ where a similar triangle singularity generates an $X^-(3876)$-like peak.

description: The CP-violating charge asymmetry in decays K+- --> π+- γγ, which is induced by the electromagnetic penguin operators, has been studied both in thestandard model and in its extensions. Because of a large enhancement of the Wilson coefficients of the electromagnetic penguin operators in the supersymmetric extensions of the standard model, a significant upper bound on this charge asymmetry could be expected, and thus high precision measurements of this interesting CP-violating quantity might explore new physics effects beyond the standard model.

description: This abstract summarizes the work published as an ICSE 2021 research track paper ''Supporting Quality Assurance with Automated Process-Centric Quality Constraints Checking'' available at https://doi.org/10.1109/ICSE43902.2021.00118 . We propose an approach that, on the one hand, assists in checking compliance with traceability requirements but, on the other hand, allows engineers to temporarily deviate from the prescribed software engineering process. Through the observation of developer activities in the form of changes to engineering artifacts in tools such as Jira or Jama, we build up a representation of the ongoing process progress. This tracking in the background does not force the software developer to work only on activities as defined in a process description. At the same time, it enables us to provide timely feedback to the developer on whether tasks fulfill all QA criteria. This approach lifts the burden off QA engineers in manually checking QA constraints, often a time-consuming, tedious, and error-prone task where feedback reaches developers usually very late. We evaluate our approach by applying it to two different case studies; one open source community system and a safety-critical system in the air-traffic control domain. Results from the analysis show that trace links are often corrected or completed after the fact and thus timely and automated constraint checking support has significant potential on reducing rework.
Practical Strategies for Integrating a Conversation Analyst in an Iterative Design Process

description: We present a case study of an iterative design process that includes a conversation analyst. We discuss potential benefits of conversation analysis for design, and we describe our strategies for integrating the conversation analyst in the design process. Since the analyst on our team had no previous exposure to design or engineering, and none of the other members of our team had any experience with conversation analysis, we needed to build a foundation for our interaction. One of our key strategies was to pair the conversation analyst with a designer in a highly interactive collaboration. Our tactics have been effective on our project, leading to valuable results that we believe we could not have obtained using another method. We hope that this paper can serve as a practical guide to those interested in establishing a productive and efficient working relationship between a conversation analyst and the other members of a design team.

description: When we are confronted with performance issues in a general-purpose language, like Java, it is a given to us that we have various tools and techniques at our disposal to help us. But is such support also needed when using model transformation languages? To address this question, we conducted a quantitative online survey as part of a mixed methods study with 84 respondents to our questionnaire. Our results show that a certain performance is desired but not always achieved. The developers would like to improve the performance, but they lack insights on how a transformation is performed. As a first step to mitigate this issue, we compiled a list of information regarding the models used, the transformations applied and their execution deemed to be helpful by the participants. Additionally, we used hypotheses tests to investigate possible influencing factors that cause participants to try to improve the performance of transformations. The main relevant factors found in our study are the satisfaction with the execution time, the size of the models used, the relevance of whether a certain execution time is not exceeded in the average case, and the knowledge of how a transformation engine executes a transformation.

description: Elliptical galaxy nuclei are the sites of the largest black holes known, but typically show little or no nuclear activity. We investigate this extreme quiescence using Chandra X-ray Observatory observations of the giant elliptical galaxies NGC 1399, NGC 4472, and NGC 4636. The unique Chandra imaging power enables us to place upper limits of 7.3, 15 and 28 X 10^-9 the Eddington luminosity for the 0.1-1 billion solar mass black holes in NGC 1399, NGC 4472, and NGC 4636, respectively. The corresponding radiative efficiencies in this band are 4.1, 24, and 620 X 10^-6 using Bondi accretion rates derived from the Chandra hot interstellar gas surface brightness profiles. These limits are inconsistent with basic advection-dominated accretion flow (ADAF) models for NGC 1399 and NGC 4472, indicating accretion onto the black hole at 10% of the Bondi rate.

description: Industrial control systems (e.g. programmable logic control\-lers, PLC or distributed control systems, DCS) cyclically execute control algorithms to automated production processes. Nowadays, for many applications their deployment is moving from dedicated embedded controllers into more flexible container environments, thus becoming ''Virtual PLCs''. It is difficult to update such containerized Virtual PLCs during runtime by switching to a newer instance, which requires transferring internal state. Former research has only proposed dynamic update approaches for single embedded controllers, while other work introduced special Kubernetes (K8s) state replication approaches, which did not support cyclic real-time applications. We propose a dynamic update mechanism for Virtual PLCs deployed as K8s microservices. This approach is based on a purpose-built K8s Operator and allows control application updates without halting the production processes. Our experimental validation shows that the approach can support the internal state transfer of large industrial control applications (100.000 state variables) within only 15 percent of the available cycle slack time. Therefore, the approach creates vast opportunities for updating applications on-the-fly and migrating them between nodes in a cloud-native fashion.

description: A detailed compilation of uncertainties in the MSbar bottom quark mass m_b(m_b) obtained from low-n spectral sum rules at order alpha_s^2 is given including charm mass effects and secondary b production. The experimental continuum region above 11.1 GeV is treated conservatively. An inconsistency of the PDG averages for the electronic partial widths of Upsilon(4S) and Upsilon(5S) is pointed out. From our analysis we obtain m_b(m_b)=4.20\pm 0.09 GeV. The impact of future CLEO data is discussed.
