description: We consider networks of finite-state machines having local transitions conditioned by the current state of other automata. In this paper, we depict a reduction procedure tailored for a given reachability property of the form ``from global state s there exists a sequence of transitions leading to a state where an automaton g is in a local state T'. By exploiting a causality analysis of the transitions within the individual automata, the proposed reduction removes local transitions while preserving all the minimal traces that satisfy the reachability property. The complexity of the procedure is polynomial in the total number of local states and transitions, and exponential in the number of local states within one automaton. Applied to automata networks modelling dynamics of biological systems, we observe that the reduction shrinks down significantly the reachable state space, enhancing the tractability of the model-checking of large networks.

description: Background
 Human factors and safe practice work synergistically to enhance patient safety in the workplace. patient safety is a General Medical Council (GMC) core domain and requirement for medical students. Moreover, the GMC’s recent inclusion of human factors in fitness to practice evaluations, demonstrates the importance of these principles to medical students’ future practice. The methodology of how to teach human factors in an engaging and relevant way is not currently standardised. We aimed to assess whether the use of contemporary fictional media improves medical student understanding and confidence relating to human factors.

 Methods
 Third- and final-year medical students from the University of Bristol attended a teaching session incorporating contemporary fictional media. Sections of the BBC’s ‘This Is Going to Hurt’, focusing on human factors leading to a patient safety incident, were used to facilitate discussion and inform of current application of patient safety measures and error reporting within the NHS. Students were surveyed to establish baseline human factors knowledge and quantify hours of previous human factors teaching. using a five-point Likert scale, student confidence, views on the relevance of human factors teaching and whether more teaching should be incorporated into the curriculum was assessed before and after the session. Comparative survey questions were analysed using the Wilcoxon-Signed-Rank Test.

 Results
 24 students attended the session. 21 students (87.5%) reported increased confidence identifying human factors after teaching (Z=-3.86, P=0.00012). Student agreement that human factors are relevant to their future practice significantly increased following the session (Z=-2.83, P=0.0047). Moreover, 22 students (95.8%) agreed medical school curricula should include more human factors teaching. 100% agreed that the session was useful, while 95.8% agreed that it would impact their future practice. Students found the incorporation of contemporary media “relevant”, “engaging” and “a good example of human factors and system failures”.

 Discussion And Conclusion
 Using contemporary media provides an engaging teaching tool to deliver challenging and conceptually difficult human factors concepts. Despite the use of fictional media, this method increased student confidence identifying human factors and their agreement that human factors are relevant to their future practice, helping prevent potential errors and promote patient safety. Incorporating contemporary media is a valid, alternative method to standardise human factors teaching within medical school curricula.

description: Posttranslational modifications of proteins can impact their therapeutic efficacy, stability, and potential for pharmaceutical development. The Group AStreptococcus pyogenesC5a peptidase (ScpA) is a multi-domain protein composed of an N-terminal signal peptide, a catalytic domain (including propeptide), three fibronectin domains, and cell membrane-associated domains. It is one of several proteins produced by Group AS. pyogenesknown to cleave components of the human complement system. After signal peptide removal, ScpA undergoes autoproteolysis and cleaves its propeptide for full maturation. The exact location and mechanism of the propeptide cleavage, and the impact of this cleavage on stability and activity, are not clearly understood, and the exact primary sequence of the final enzyme is not known. A form of ScpA with no autoproteolysis fragments of propeptide present may be more desirable for pharmaceutical development from a regulatory and a biocompatibility in the body perspective. The current study describes an in-depth structural and functional characterization of propeptide truncated variants of ScpA expressed inEscherichia colicells. All three purified ScpA variants, ScpA, 79ΔPro, and 92ΔPro, starting with N32, D79, and A92 positions, respectively, showed similar activity against C5a, which suggests a propeptide-independent activity profile of ScpA. CE-SDS and MALDI top-down sequencing analyses highlight a time-dependent propeptide autoproteolysis of ScpA at 37 °C with a distinct end point at A92 and/or D93. In comparison, all three variants of ScpA exhibit similar stability, melting temperatures, and secondary structure orientation. In summary, this work not only highlights propeptide localization but also provides a strategy to recombinantly produce a final mature and active form of ScpA without any propeptide-related fragments.

description: A picture of confinement in QCD based on a condensate of thick vortices with fluxes in the center of the gauge group (center vortices) is studied. Previous concrete model realizations of this picture utilized a hypercubic space-time scaffolding, which, together with many advantages, also has some disadvantages, e.g., in the treatment of vortex topological charge. In the present work, we explore a center vortex model which does not rely on such a scaffolding. Vortices are represented by closed random lines in continuous 2+1-dimensional space-time. These random lines are modeled as being piece-wise linear, and an ensemble is generated by Monte Carlo methods. The physical space in which the vortex lines are defined is a torus with periodic boundary conditions. Besides moving, growing and shrinking of the vortex configurations, also reconnections are allowed. Our ensemble therefore contains not a fixed, but a variable number of closed vortex lines. This is expected to be important for realizing the deconfining phase transition. We study both vortex percolation and the potential V (R) between quark and anti-quark as a function of distance R at different vortex densities, vortex segment lengths, reconnection conditions and at different temperatures. We find three deconfinement phase transitions, as a function of density, as a function of vortex segment length, and as a function of temperature.

description: In a world of constantly changing dynamics of lifestyle and health-culture, it has become necessary for individuals to constantly keep a check on their diet and its contents. Increasing levels of pollution and stress negatively affects both, the health and longevity of an individual. Owing to a decline in average health, more and more people today have started looking for alternatives that could make their diet cleaner and healthier. One such alternative identified is organic produce, which is 100% chemical free, and therefore healthier than conventionally produced food products. However, organic produce is highly expensive, making it less attractive to the masses. Aquaponics, is one such technique of producing organic vegetables in a sustainable manner, thereby reducing its cost. This paper aims to understand the awareness levels of Aquaponics as a technique of organic agriculture. The study performs various tests in order to understand the levels of awareness of Aquaponically grown organic produce within the country. The findings of the study prove that factors such as the prices of organic vegetables, their availability and brand recognition play a major role in influencing the purchase decision made by consumers. On the other hand, factors such as education levels of the consumers or their income levels do not have a major impact on their purchase patterns of organic vegetables. Further analysis revealed that greater awareness about Aquaponics in general, and increased production of organic vegetables through Aquaponics also has a positive impact on the purchase of such vegetables.

description: We investigate the relationship between X-ray cooling and star formation in brightest cluster galaxies (BCGs). We present an X-ray spectral analysis of the inner regions, 10-40 kpc, of six nearby cool core clusters (z<0.35) observed with Chandra ACIS. This sample is selected on the basis of the high star formation rate (SFR) observed in the BCGs. We restrict our search for cooling gas to regions that are roughly cospatial with the starburst. We fit single- and multi-temperature mkcflow models to constrain the amount of isobarically cooling intracluster medium (ICM). We find that in all clusters, below a threshold temperature ranging between 0.9 and 3 keV, only upper limits can be obtained. In four out of six objects, the upper limits are significantly below the SFR and in two, namely A1835 and A1068, they are less than a tenth of the SFR. Our results suggests that a number of mechanisms conspire to hide the cooling signature in our spectra. In a few systems the lack of a cooling signature may be attributed to a relatively long delay time between the X-ray cooling and the star burst. However, for A1835 and A1068, where the X-ray cooling time is shorter than the timescale of the starburst, a possible explanation is that the region where gas cools out of the X-ray phase extends to very large radii, likely beyond the core of these systems.

description: Landscape renderings are realistic images of landscape sites, allowing stakeholders to perceive better and evaluate design ideas. While recent advances in Generative Artificial Intelligence (GAI) enable automated generation of landscape renderings, the end-to-end methods are not compatible with common design processes, leading to insufficient alignment with design idealizations and limited cohesion of iterative landscape design. Informed by a formative study for comprehending design requirements, we present PlantoGraphy, an iterative design system that allows for interactive configuration of GAI models to accommodate human-centered design practice. A two-stage pipeline is incorporated: first, concretization module transforms conceptual ideas into concrete scene layouts with a domain-oriented large language model; and second, illustration module converts scene layouts into realistic landscape renderings using a fine-tuned low-rank adaptation diffusion model. PlantoGraphy has undergone a series of performance evaluations and user studies, demonstrating its effectiveness in landscape rendering generation and the high recognition of its interactive functionality.

description: The practice of the double-cropping system (DCS), whereby farmers plant two different crops in the same field, in succession, within the same crop year, has been growing in the tropical regions of Brazil for the last 40 years. The DCS, also known as the ‘‘safrinha’’ system, has been responsible for an important revolution in cropping production in the tropics, a region historically challenged by low agricultural productivity. The system allows the intensification of land use, raises total production per hectare per year, and improves asset use efficiency, for example machinery, facilities, and human capital. The goal of this paper is to better understand the DCS system for tropical agricultural managers. Specifically, the manuscript achieves that goal by exploring the decision-making by farm managers through direct semistructured interviews with experienced DCS managers. The direct engagement is unique as it intentionally complements previous more indirect survey-based and econometric methodologies. The setting is Mato Grosso Brazil, the center of DCS farming in the tropics. The findings directly apply to producers in other tropical regions of the world, where some of the poorest countries reside. Policymakers and investors can integrate the findings from this paper to better design farming systems to improve productivity and profitability among small and medium sized farmers operating in the tropics.

description: A graph is \textit{locally irregular} if the neighbors of every vertex $v$ have degrees distinct from the degree of $v$. \textit{locally irregular edge-coloring} of a graph $G$ is an (improper) edge-coloring such that the graph induced on the edges of any color class is locally irregular. It is conjectured that $3$ colors suffice for a locally irregular edge-coloring. Recently, Bensmail et al. (Bensmail, Merker, Thomassen: Decomposing graphs into a constant number of locally irregular subgraphs, {\em European J. Combin.}, 60:124--134, 2017) settled the first constant upper bound for the problem to $328$ colors. In this paper, using a combination of existing results, we present an improvement of the bounds for bipartite graphs and general graphs, setting the best upper bounds to $7$ and $220$, respectively. In addition, we also prove that $4$ colors suffice for locally irregular edge-coloring of any subcubic graph.

description: Residual networks (ResNets) have significantly better trainability and thus performance than feed-forward networks at large depth. Introducing skip connections facilitates signal propagation to deeper layers. In addition, previous works found that adding a scaling parameter for the residual branch further improves generalization performance. While they empirically identified a particularly beneficial range of values for this scaling parameter, the associated performance improvement and its universality across network hyperparameters yet need to be understood. For feed-forward networks (FFNets), finite-size theories have led to important insights with regard to signal propagation and hyperparameter tuning. We here derive a systematic finite-size theory for ResNets to study signal propagation and its dependence on the scaling for the residual branch. We derive analytical expressions for the response function, a measure for the network's sensitivity to inputs, and show that for deep networks the empirically found values for the scaling parameter lie within the range of maximal sensitivity. Furthermore, we obtain an analytical expression for the optimal scaling parameter that depends only weakly on other network hyperparameters, such as the weight variance, thereby explaining its universality across hyperparameters. Overall, this work provides a framework for theory-guided optimal scaling in ResNets and, more generally, provides the theoretical framework to study ResNets at finite widths.

description: Rare diseases are recognized as non-prevalent health disorders. Availability, accessibility, and affordability of Orphan Drugs (ODs), alongside genetic testing, are the major contributors to ensuring no patient is excluded by the health system. Therefore, making ODs available and accessible has been a challenge even for high-income nations. This review aims to summarize the evidence on the availability and accessibility of orphan drugs and other required resources for managing rare diseases. The Joanna Briggs Institute scoping review method was used as the analytical framework. We searched Medline, and Embase through Ovid, and Web of Science. We used Guilford et al. definition and classification of accessibility and its dimensions to synthesize the evidence. The majority of the final included evidence is about the financial, and then availability and physical accessibility to ODs. Furthermore, almost all the evidence comes from high-income countries. The principal hurdles to the availability and accessibility of ODs and other related services are very high prices, lack of a legal framework, and budgetary impact on public funding. A lack of reimbursement mechanisms and lower availability of other resources are among other problems.

description: Dramatic deficiencies of Li in the mid-F dwarf stars of the Hyades cluster were discovered by Boesgaard & Tripicco. Boesgaard & King discovered corresponding, but smaller, deficiencies in Be in the same narrow temperature region in the Hyades. With the Space Telescope Imaging Spectrograph on the Hubble Space Telescope we investigate B abundances in the Hyades F stars to look for a potential B dip using the B I resonance line at 2496.8 A. The light elements, Li, Be, and B, are destroyed inside stars at increasingly hotter temperatures: 2.5, 3.5, and 5x10^6 K respectively. Consequently, these elements survive to increasingly greater depths in a star and their surface abundances indicate the depth and thoroughness of mixing in the star. We have (re)determined Li abundances/upper limits for 79 Hyades dwarfs, Be for 43 stars, and B in five stars. We find evidence for a small drop in the B abundance across the Li-Be dip. The B abundances for the four stars in the temperature range 6100-6730 K fit the B-Be correlation found previously by Boesgaard et al. Models of rotational mixing produce good agreement with the relative depletions of Be and B in the dip region. We have compared our nLTE B abundances for the three high B stars on either side of the Li-Be dip with those found by Duncan et al. for the two Hyades giants. This confirms the factor of ~10 decline in the B abundance in the Hyades giants as predicted by dilution due to the deepening of the surface convection zone.

description: In recent years the need for DC distribution buses has increased considerably. As it can be noticed in the transport for example the distribution systems of the more electric aircrafts, ships, or electric cars. Given the complexities of the systems presented above, the need to use more and more switched power converters has arisen. The main problem of the connection of multiple controlled switched converters acting as source and load is the degradation of stability that occurs on the DC distribution bus due to the converter interactions. To study the stability in the distribution bus there are some wellestablished criteria. These criteria require knowledge of the input impedance of the converters that act as load and the output impedance of the equipment that acts as source. In order to reduce the complexity of obtaining the input impedance a model based on a controlled converter acting as a constant power load (CPL) is commonly used. This article studies the accuracy of this model for a commonly used topology in distribution systems nowadays, Two Level Voltage Source Converter (2L-VSC), studying different scenarios that make the model become inaccurate.

description: Hyper doping Si with up to 6 at.% Ti in solid solution was performed by ion implantation followed by pulsed laser annealing and flash lamp annealing. In both cases, the implanted Si layer can be well recrystallized by liquid phase epitaxy and solid phase epitaxy, respectively. Cross-sectional transmission electron microscopy of Ti-implanted Si after liquid phase epitaxy shows the so-called growth interface breakdown or cellular breakdown owing to the occurrence of constitutional supercooling in the melt. The appearance of cellular breakdown prevents further recrystallization. However, the out-diffusion and cellular breakdown can be effectively suppressed by solid phase epitaxy during flash lamp annealing due to the high velocity of amorphous-crystalline interface and the low diffusion velocity for Ti in the solid phase.

description: Application of fitting techniques to obtain physical parameters---such as ages, metallicities, and $α$-element to iron ratios---of stellar populations is an important approach to understand the nature of both galaxies and globular clusters (GCs). In fact, fitting methods based on different underlying models may yield different results, and with varying precision. In this paper, we have selected 22 confirmed M31 GCs for which we do not have access to previously known spectroscopic metallicities. Most are located at approximately one degree (in projection) from the galactic center. We performed spectroscopic observations with the 6.5 m MMT telescope, equipped with its Red Channel Spectrograph. Lick/IDS absorption-line indices, radial velocities, ages, and metallicities were derived based on the $\rm EZ\_Ages$ stellar population parameter calculator. We also applied full spectral fitting with the ULySS code to constrain the parameters of our sample star clusters. In addition, we performed $χ^2_{\rm min}$ fitting of the clusters' Lick/IDS indices with different models, including the Bruzual & Charlot models (adopting Chabrier or Salpeter stellar initial mass functions and 1994 or 2000 Padova stellar evolutionary tracks), the GALEV, and the Thomas et al. models. For comparison, we collected their $UVBRIJK$ photometry from the Revised Bologna Catalogue (v.5) to obtain and fit the GCs' spectral energy distributions (SEDs). Finally, we performed fits using a combination of Lick/IDS indices and SEDs. The latter results are more reliable and the associated error bars become significantly smaller than those resulting from either our Lick/IDS indices-only or our SED-only fits.

description: The mechanical behaviors of polycrystalline solids are determined by the interplay between phenomena governed by two different thermodynamic temperatures: the configurational effective temperature that controls the density of dislocations, and the ordinary kinetic-vibrational temperature that controls activated depinning mechanisms and thus deformation rates. This paper contains a review of the effective-temperature theory and its relation to conventional dislocation theories. It includes a simple illustration of how these two thermal effects can combine to produce a predictive theory of spatial heterogeneities such as shear-banding instabilities. Its main message is a plea that conventional dislocation theories be reformulated in a thermodynamically consistent way so that the vast array of observed behaviors can be understood systematically.

Nonverbal Communication During Human-Robot Object Handover. Improving Predictability of Humanoid Robots by Gaze and Gestures in Close Interaction
Creators: name: Meyer zu Borgsen, Sebastian
Publisher: name: Universität Bielefeld

Subjects: subject: 000

description: This doctoral thesis investigates the influence of nonverbal communication on human-robot object handover. Handing objects to one another is an everyday activity where two individuals cooperatively interact. Such close interactions incorporate a lot of nonverbal communication in order to create alignment in space and time. Understanding and transferring communication cues to robots becomes more and more important as e.g. service robots are expected to closely interact with humans in the near future. Their tasks often include delivering and taking objects. Thus, handover scenarios play an important role in human-robot interaction. A lot of work in this field of research focuses on speed, accuracy, and predictability of the robot’s movement during object handover. Still, robots need to be enabled to closely interact with naive users and not only experts. In this work I present how nonverbal communication can be implemented in robots to facilitate smooth handovers. I conducted a study on people with different levels of experience exchanging objects with a humanoid robot. It became clear that especially users with only little experience in regard to interaction with robots rely heavily on the communication cues they are used to on the basis of former interactions with humans. I added different gestures with the second arm, not directly involved in the transfer, to analyze the influence on synchronization, predictability, and human acceptance. Handing an object has a special movement trajectory itself which has not only the purpose of bringing the object or hand to the position of exchange but also of socially signalizing the intention to exchange an object. Another common type of nonverbal communication is gaze. It allows guessing the focus of attention of an interaction partner and thus helps to predict the next action. In order to evaluate handover interaction performance between human and robot, I applied the developed concepts to the humanoid robot Meka M1. By adding the humanoid robot head named Floka Head to the system, I created the Floka humanoid, to implement gaze strategies that aim to increase predictability and user comfort. This thesis contributes to the field of human-robot object handover by presenting study outcomes and concepts along with an implementation of improved software modules resulting in a fully functional object handing humanoid robot from perception and prediction capabilities to behaviors enhanced and improved by features of nonverbal communication.

In this paper, we propose a general method, based on the delay spectrum approach, to extract HI power spectra that is applicable to tracking observations using an imaging radio interferometer (Delay Spectrum with Imaging Arrays (DSIA)). Our method is based on modelling the HI signal taking into account the impact of wide field effects such as the $w$-term which are then used as appropriate weights in cross-correlating the measured visibilities. Our method is applicable to any radio interferometer that tracks a phase center and could be utilized for arrays such as MWA, LOFAR, GMRT, PAPER and HERA. In the literature the delay spectrum approach has been implemented for near-redundant baselines using drift scan observations. In this paper we explore the scheme for non-redundant tracking arrays, and this is the first application of delay spectrum methodology to such data to extract the HI signal. We analyze 3 hours of MWA tracking data on the EoR1 field. We present both 2-dimensional ($k_\parallel,k_\perp$) and 1-dimensional (k) power spectra from the analysis. Our results are in agreement with the findings of other pipelines developed to analyse the MWA EoR data.

description: A key challenge for supporting elastic behaviour in cloud systems is to achieve a good performance in automated (de-)provisioning and scheduling of computing resources. One of the key aspects that can be significant is the overheads associated with deploying, terminating and maintaining resources. Therefore, due to their lower start up and termination overhead, containers are rapidly replacing Virtual Machines (VMs) in many cloud deployments, as the computation instance of choice. In this paper, we analyse the performance of Kubernetes achieved through a Petri net-based performance model. Kubernetes is a container management system for a distributed cluster environment. Our model can be characterised using data from a Kubernetes deployment, and can be exploited for supporting capacity planning and designing Kubernetes-based elastic applications.

description: In this paper, we address the formal characterization of targets triggering cellular trans-differentiation in the scope of Boolean networks with asynchronous dynamics. Given two fixed points of a Boolean network, we are interested in all the combinations of mutations which allow to switch from one fixed point to the other, either possibly, or inevitably. In the case of existential reachability, we prove that the set of nodes to (permanently) flip are only and necessarily in certain connected components of the interaction graph. In the case of inevitable reachability, we provide an algorithm to identify a subset of possible solutions.

description: Mechanization and technology in agriculture are becoming more and more evident, not only in developed countries, but also in African countries, and more specifically South Africa. The objectives of the study were to identify the factors that impact labourers when wine grape harvesters are used on farms in the Western Cape Province of South Africa by answering the research question of ‘‘Which factors affect labour usage on farms that use mechanical harvesters for harvesting grapes?’’ The study utilized a survey, secondary data, and a binomial logistic regression model. The study shows that increasing hectares used for the production of wine grapes, farmer’s age, machine output and average labour output has a significant impact on the reduction of seasonal labour as well as permanent labour on the farms. The study recommends that the government should intervene or introduce legislation to mitigate the effect of mechanical harvesting of grapes on labour. The government should encourage producers to keep farm workers, given technological advances, which discourage the retrenchment of farmers who apply technology advancement, but retain labourers. The government can also provide incentives to producers who apply technological advancement, but retain labourers.
Sharp estimates for biorthogonal families to exponential functions associated to complex sequences without gap conditions

description: The general goal of this work is to obtain upper and lower bounds for the $L^2$-norm of biorthogonal families to complex exponential functions associated to sequences $\{ Λ_k \}_{k \ge 1} \subset \mathbb C$ which satisfy appropriate assumptions but without imposing a gap condition on the elements of the sequence. As a consequence, we also present new results on the cost of the boundary null controllability of two parabolic systems at time $T > 0$: a phase-field system and a parabolic system whose generator has eigenvalues that accumulate. In the latter case, the behavior of the control cost when $T$ goes to zero depends strongly on the accumulation parameter of the eigenvalue sequence.

description: The determination of the properties of neutron stars from the underlying theory, QCD, is still an unsolved problem. This is mainly due to the difficulty to obtain reliable results for the equation of state for cold, dense QCD. As an alternative route to obtain qualitative insights, we determine the structure of a neutron star for a modified version of QCD: By replacing the gauge group SU(3) with the exceptional Lie group G2, it is possible to perform lattice simulations at finite density, while still retaining neutrons. Here, results of these lattice simulations are used to determine the mass-radius relation of a neutron star for this theory. The results show that phase changes express themselves in this relation. Also, the radius of the most massive neutron stars is found to vary very little, which would make radius determinations much simpler if this would also be true in QCD.

description: The Green Deal is a European Commission response to promote zero net emissions of greenhouse gases by 2050 in the European Union. Its multiple strategies, including circular economy and agriculture, should impact all citizens. To improve the literacy of primary school students in environmental and sustainability concepts, namely those included in the Green Deal strategies, the pilot project "Nutrients Boomerang" was implemented as part of the Environmental Education strategy of a Portuguese science centre, Fábrica Ciência Viva. The project included the implementation of an outdoor model area, focusing on composting and urban vegetable gardening, complemented with workshops on biodiversity, circular economy, and organic farming, targeting primary school students. This pilot project was implemented from January to September 2021 and in its final months was also organized in a way to include the students’ families, given their willingness to introduce parents and grandparents to the activities they had been doing. This pilot project showed its suitability to be replicated in primary school outdoor green areas and so promote hands on activities aiming to foster in young students a conscientious behaviour towards a more sustainable world.

description: Renewable energy plays an important role in India's energy security and reducing greenhouse gas emissions. Energy generated at the centralized level has significant shortcomings, and environmental concerns drive a shift to decentralized energy. India is a developing country; renewable energy power generation promotion is very important to make awareness among consumers and retailers. India's energy transition and decarbonization agenda aim to build a new clean energy system that is reliable, affordable, sustainable, and energy independent. The Indian government has taken several initiatives to increase domestic manufacturing capacity, particularly solar PV, electric vehicles, and batteries. This paper aims to present significant achievements through different RE schemes, projections, and India’s ambition of net zero through the current policy in place concerning the decentralized use of renewable technologies prospects.
