description: We have estimated the critical exponent describing the divergence of the localization length at the metal-quantum spin Hall insulator transition. The critical exponent for the metal-ordinary insulator transition in quantum spin Hall systems is known to be consistent with that of topologically trivial symplectic systems. However, the precise estimation of the critical exponent for the metal-quantum spin Hall insulator transition proved to be problematic because of the existence, in this case, of edge states in the localized phase. We have overcome this difficulty by analyzing the second smallest positive Lyapunov exponent instead of the smallest positive Lyapunov exponent. We find a value for the critical exponent $ν=2.73 \pm 0.02$ that is consistent with that for topologically trivial symplectic systems.

description: Process models are important for supporting organizations in documenting, understanding and monitoring their business. When these process models become outdated, they need to be revised to accurately describe the new status quo of the processes in the organization. Process model repair techniques help at automatically revising the existing model from behavior traced in event logs. So far, such techniques have focused on identifying which parts of the model to change and how to change them, but they do not use knowledge from practitioners to inform the revision. As a consequence, fragments of the model may change in a way that defies existing regulations or represents outdated information that was wrongly considered from the event log. This paper uses concepts from theory revision to provide formal foundations for process model repair that exploits domain knowledge. Specifically, it conceptualizes (1) what are unchangeable fragments in the model and (2) the role that various traces in the event log should play when it comes to model repair. A scenario of use is presented that demonstrates the benefits of this conceptualization. The current state of existing process model repair techniques is compared against the proposed concepts. The results show that only two existing techniques partially consider the concepts presented in this paper for model repair.

description: Teaching intercultural communication presents many challenges, particularly at predominantly white institutions (PWI). Individuals who hold majority identities may have difficulty seeing their own culture or race and, relatedly, the value of intercultural communication for their lives. Additionally, students who hold marginalized or minoritized identities can feel the burden of being cultural ambassadors in classroom discussions, creating an inequitable labor burden. Moreover, students of all identities may experience discomfort related to conversations about culture. This semester-long assignment seeks to address those challenges by contextualizing culture in a way that can be applied to all students, regardless of the identities they hold. The Food for Thought assignment is a third-culture-building exercise designed to teach students about culture and intercultural communication through a communal dining experience. Any full-semester intercultural communication course of approximately 40 students, but can be adapted for any course with a cultural component (e.g. interpersonal communication or the basic/foundational course) by limiting dining to one or two class periods. The activity aims to help students learn about and foster community through third-culture building, to develop intercultural sensitivity and respect for cultural differences, to recognize and introspect on one’s own culture, and to connect lived experience to theory.

description: We present an SPH parameter study of the dynamical effect of photoionization from O--type stars on star--forming clouds of a range of masses and sizes during the time window before supernovae explode. Our model clouds all have the same degree of turbulent support initially, the ratio of turbulent kinetic energy to gravitational potential energy being set to $E_{\rm kin}/|E_{\rm pot}|$=0.7. We allow the clouds to form stars and study the dynamical effects of the ionizing radiation from the massive stars or clusters born within them. We find that dense filamentary structures and accretion flows limit the quantities of gas that can be ionized, particularly in the higher density clusters. More importantly, the higher escape velocities in our more massive (10$^{6}$M$_{\odot}$) clouds prevent the HII regions from sweeping up and expelling significant quantities of gas, so that the most massive clouds are largely dynamically unaffected by ionizing feedback. However, feedback has a profound effect on the lower--density 10$^{4}$ and 10$^{5}$M$_{\odot}$ clouds in our study, creating vast evacuated bubbles and expelling tens of percent of the neutral gas in the 3Myr timescale before the first supernovae are expected to detonate, resulting in clouds highly porous to both photons and supernova ejecta.

description: Radical-ion-pair reactions were recently shown to represent a rich biophysical laboratory for the application of quantum measurement theory methods and concepts. We here propose a concrete experimental test that can clearly discriminate among the fundamental master equations currently attempting to describe the quantum dynamics of these reactions. The proposed measurement based on photon statistics of fluorescing radical pairs is shown to be model-independent and capable of elucidating the singlet-triplet decoherence inherent in the radical-ion-pair recombination process.

description: Background: Type 1 diabetes in young children is a heavy parental burden. As part of pilot phase of the KIDSAP01 study, we conducted a baseline assessment in parents to study the association between hypoglycemia fear, parental well-being and child behavior. Methods: All parents were invited to fill in baseline questionnaires: hypoglycemia fear survey (HFS), WHO-5, Epworth Sleepiness Scale and Strength and Difficulties Questionnaire (SDQ). Results: 24 children (median age: 5-year, range 1-7 years, 63% male, mean diabetes duration: 3 ± 1.7 years) participated. 23/24 parents filled out the questionnaires. We found a higher score for the hypoglycemia fear behavior 33.9 ± 5.6 compared to hypoglycemia worry 34.6 ± 12.2. Median WHO-5 score was 16 (8 - 22) with poor well-being in two parents. Median daytime sleepiness score was high in five parents (>10). For six children a high total behavioral difficulty score (>16) was reported. Pro social behavior score was lower than normal in six children (<6). Parental well-being was negatively associated with HFS total (r = - 0.50, p

description: Ebolaviruses continue to pose a significant outbreak threat, and while Ebola virus (EBOV)-specific vaccines and antivirals have been licensed, efforts to develop candidates offering broad species cross-protection are continuing. The use of pseudotyped virus in place of live virus is recognised as an alternative, safer, high-throughput platform to evaluate anti-ebolavirus antibodies towards their development, yet it requires optimisation. Here, we have shown that the target cell line impacts neutralisation assay results and cannot be selected purely based on permissiveness. In expanding the platform to incorporate each of the ebolavirus species envelope glycoprotein, allowing a comprehensive assessment of cross-neutralisation, we found that the recently discovered Bombali virus has a point mutation in the receptor-binding domain which prevents entry into a hamster cell line and, importantly, shows that this virus can be cross-neutralised by EBOV antibodies and convalescent plasma.

description: e-Motions is an Eclipse-based visual timed model transformation framework with a Real-Time Maude semantics that supports the usual Maude formal analysis methods, including simulation, reachability analysis, and LTL model checking. e-Motions is characterized by a novel and powerful set of constructs for expressing timed behaviors. In this paper we illustrate the use of these constructs --- and thereby implicitly investigate their suitability to define real-time systems in an intuitive way --- to define and formally analyze two prototypical and very different real-time systems: (i) a simple round trip time protocol for computing the time it takes a message to travel from one node to another, and back; and (ii) the EDF scheduling algorithm.

description: Astrophysical fluids are generally turbulent and this preexisting turbulence must be taken into account for the models of magnetic reconnection which are attepmted to be applied to astrophysical, solar or heliospheric environments. In addition, reconnection itself induces turbulence which provides an important feedback on the reconnection process. In this paper we discuss both theoretical model and numerical evidence that magnetic reconnection gets fast in the approximation of resistive MHD. We consider the relation between the Lazarian & Vishniac turbulent reconnection theory and Lapenta's numerical experiments testifying of the spontaneous onset of turbulent reconnection in systems which are initially laminar.

An effective transition from one- to two-dimensional system is achieved by increasing the number of rows forming the arrays. We observe that, for a given disorder level, Anderson localization becomes weaker with increasing number of rows, hence the effective dimension.

Year: 2023

description: Research Infrastructures (RI) are facilities that offer resources and services for research communities to conduct research and promote innovation. RI can be a single site or distributed and include major scientific equipment, collections, archives or scientific data, computing systems and communication networks.Interoperability is an important aspect of Open Science (OS). It refers to the ability of different systems and organizations to work together and exchange information seamlessly. Interoperability involves establishing common standards, formats, and protocols that enable different systems or components to communicate with each other and exchange the data without loss or distortion of information. Data interoperability addresses challenges related to data compatibility, structure, semantics, and technical integration. It involves defining and adhering to shared data models, schema, and metadata standards, as well as utilizing common communication protocols and interfaces. In the context of OS, interoperability allows for the integration and interconnection of research infrastructures, reducing the fragmentation of the research and innovation ecosystem and avoiding the duplication of effort. Achieving interoperability across resources and services within RIs can present several challenges. Most of the interoperability challenges can be divided into two blocks, namely technical and social challenges.In conclusion, RIs are crucial for promoting scientific research and driving innovation in various fields. To maximize their impact, achieving interoperability is a key challenge that needs to be addressed. Centralized hubs of standards, such as common vocabularies and data formats, can facilitate communication and collaboration among research infrastructures. Improved communication and coordination among research infrastructures can also help prevent the duplication of effort and increase efficiency. These initiatives are essential for accelerating scientific progress, bridging gaps, and improving the usability of RIs.

description: Currently we routinely develop a complex neuronal network to explain observed but often paradoxical phenomena based upon biological recordings. Here we present a general approach to demonstrate how to mathematically tackle such a complex neuronal network so that we can fully understand the underlying mechanism. Using an oxytocin network developed earlier as an example, we show how we can reduce a complex model with many variables to a tractable model with two variables, while retaining all key qualitative features of the model. The approach enables us to uncover how emergent synchronous bursting could arise from a neuronal network which embodies all known biological features. Surprisingly, the discovered mechanisms for bursting are similar to those found in other systems reported in the literature, and illustrate a generic way to exhibit emergent and multi-time scale spikes: at the membrane potential level and the firing rate level.

description: A formal definition of the semantics of a domain-specific language (DSL) is a key prerequisite for the verification of the correctness of models specified using such a DSL and of transformations applied to these models. For this reason, we implemented a prototype of the semantics of a DSL for the specification of systems consisting of concurrent, communicating objects. Using this prototype, models specified in the DSL can be transformed to labeled transition systems (LTS). This approach of transforming models to LTSs allows us to apply existing tools for visualization and verification to models with little or no further effort. The prototype is implemented using the ASF+SDF Meta-Environment, an IDE for the algebraic specification language ASF+SDF, which offers efficient execution of the transformation as well as the ability to read models and produce LTSs without any additional pre or post processing.

description: WorkflowHub is the open-source registry for computational workflows and, more recently, lab protocols or Standard Operating Procedures, used in scientific research. The fundamental role of the WorkflowHub is to enhance the ability for researchers to collaborate by making their workflows visible, citable, and shareable. Thereby improving the accessibility of scientific knowledge. Underpinning this is the improvement in scientific reproducibility, transparency, and value of workflows that comes from using a registry that can make them FAIR (findable, accessible, interoperable and reusable).



WorkflowHub makes use of open standards such as the Common Workflow Language, RO-Crate, Bioschemas, and GA4GH’s TRS API.  This ecosystem integration ensures that workflows are easily discoverable, reusable, and interoperable with other tools and platforms. The Hub provides support for native git repositories and popular workflow management systems such as Galaxy and Nextflow. It integrates with services such as BBMRI-ERIC’s Life Monitor, which monitors workflow tests, and ELIXIR Bio.tools registry, to crosslink workflows with the tools they use.  



WorkflowHub is open to any workflow language and any community. Currently 20 languages are represented by 570+ workflows, and the 230+ teams registered include communities in bioscience, health, chemistry, climate change, biodiversity and astronomy. Workflows are registered for sharing amongst collaborators while they are being developed, and published with DOIs. Journals such as GigaScience have begun recommending the WorkflowHub.



WorkflowHub is led by ELIXIR and developed in partnership with the Australian BioCommons. The biweekly “WorkflowHub Club” community call guides the development of the platform.
Stability and multi-attractor dynamics of a toggle switch based on a two-stage model of stochastic gene expression

description: A toggle switch consists of two genes that mutually repress each other. This regulatory motif is active during cell differentiation and is thought to act as a memory device, being able to choose and maintain cell fate decisions. In this contribution, we study the stability and dynamics of a two-stage gene expression switch within a probabilistic framework inspired by the properties of the Pu/Gata toggle switch in myeloid progenitor cells. We focus on low mRNA numbers, high protein abundance and monomeric transcription factor binding. Contrary to the expectation from a deterministic description, this switch shows complex multi-attractor dy- namics without autoactivation and cooperativity. Most importantly, the four attractors of the system, which only emerge in a probabilistic two-stage description, can be identified with committed and primed states in cell differentiation. We first study the dynamics of the system and infer the mechanisms that move the system between attractors using both the quasi-potential and the probability flux of the system. Second, we show that the residence times of the system in one of the committed attractors are geometrically distributed and provide an analytical expression of the distribution. Most importantly we find that the mean residence time increases linearly with the mean protein level. Finally, we study the implications of this distribution for the stability of a switch and discuss the influence of the stability on a specific cell differentiation mechanism. Our model explains lineage priming and proposes the need of either high protein numbers or long term modifications such as chromatin remodeling to achieve stable cell fate decisions. Notably we present a system with high protein abundance that nevertheless requires a probabilistic description to exhibit multistability, complex switching dynamics and lineage priming.

Poster abstract:

As part of the Dutch Implementation Plan Investments Digital Research Infrastructure, three national-level Thematic Digital Competence Centres (TDCC) have been established for the scientific domains Life Sciences & Health (LSH), Natural & Engineering Sciences (NES) and Social Sciences & Humanities (SSH). The mission of the TDCCs is to tackle domain specific challenges in data driven science by a combination of network activities and dedicated project funding. 

TDCC-LSH is coordinated by Health-RI and builds on the DTL and Health-RI networks. The TDCC-LSH programme is based upon the TDCC-LSH Roadmap that has been formulated by the LSH research community. TDCC-LSH has three main ambitions:  a) Harmonisation of good data stewardship and data access practices, b) Enhancement of the interoperability of digital solutions and resources, and c) Strengthening the capacity and expertise base in digital research.   

The TDCC-LSH projects and activities connect stakeholder groups in the field of data-driven health & life sciences research, consisting of (inter)national infrastructure initiatives as well as communities of bioinformaticians, Ethical, Legal and Societal Implications (ELSI) specialists, data scientists, data stewards and research software engineers active across the broad LSH domain. On a national level we align with the local DCCs established at many research organisations and with the Dutch national agenda on Open Science. Internationally we align e.g. with ELIXIR (a.o. via the ELIXIR RDM Community and the Food & Nutrition Community) as well as with EOSC, where we are co-leading the work on data stewardship.

Hybrid SARIMA-ELM-based Data Traffic Forecasting: The Case of UMTS Network in Addis Ababa, Ethiopia
Creators: name: Getinet Tesfaye
Publisher: name: Zenodo
Year: 2018

description: In Universal Mobile Telecommunications Service (UMTS) network planning, data traffic demand is one critical input in deciding dimension of network elements. Past data collected from deployed UMTS network can be used to forecast future demand. In the context of ethio telecom, the sole telecom service provider in Ethiopia, the future demand forecast is, however, based on number of subscribers growth forecast obtained from marketing section. This approach assumes uniform data demand per subscriber to obtain the total data demand. Understandably, it does not utilize the data growth information which is already available in the network.

Forecasting the traffic demand based on historical data from network can enhance the marketing inputs and the traffic model accuracy. In this regard, taking data from ethio telecom’s UMTS network, a prior research has used Seasonal Autoregressive Integrated Moving Average (SARIMA) model to forecast a one month data traffic demand. However, the research did not consider the non-linearity observed in the data traffic. This thesis handles this non-linearity via a hybrid model that accounts the linearity with SARIMA model and the non-linearity via Extreme Learning Machine (ELM) model; here after called the hybrid SARIMA-ELM model.

description: The emission of fundamental and harmonic frequency radio waves of type II radio bursts are assumed to be products of three-wave interaction processes of beam-excited Langmuir waves. Using a particle-in-cell code, we have performed simulations of the assumed emission region, a CME foreshock with two counterstreaming electron beams. Analysis of wavemodes within the simulation shows self-consistent excitation of beam driven modes, which yield interaction products at both fundamental and harmonic emission frequencies. Through variation of the beam strength, we have investigated the dependence of energy transfer into electrostatic and electromagnetic modes, confirming the quadratic dependence of electromagnetic emission on electron beam strength.

description: Context: Hydrogen peroxide (HOOH) was recently detected toward ρOph A. Subsequent astrochemical modeling that included reactions in the gas phase and on the surface of dust grains was able to explain the observed abundance, and highlighted the importance of grain chemistry in the formation of HOOH as an intermediate product in water formation. This study also predicted that the hydroperoxyl radical HO2, the precursor of HOOH, should be detectable. Aims: We aim at detecting the hydroperoxyl radical HO2 in ρOph A. Methods: We used the IRAM 30m and the APEX telescopes to target the brightest HO2 lines at about 130 and 260 GHz. Results: We detect five lines of HO2 (comprising seven individual molecular transitions). The fractional abundance of HO2 is found to be about 1e-10, a value similar to the abundance of HOOH. This observational result is consistent with the prediction of the above mentioned astrochemical model, and thereby validates our current understanding of the water formation on dust grains. Conclusions: This detection, anticipated by a sophisticated gas-grain chemical model, demonstrates that models of grain chemistry have improved tremendously and that grain surface reactions now form a crucial part of the overall astrochemical network.

description: We present specific-heat data on the type-II superconductors V3Si, LuNi2B2C and NbSe2 which were acquired with a low-temperature thermal analysis (DTA) technique. We compare our data with available literature data on these superconductors. In the first part we show that the DTA technique allows for fast measurements while providing a very high resolution on the temperature scale. Sharp features in the specific heat such as at the one at the transition to superconductivity are resolved virtually without instrumental broadening. In the second part we investigate the magnetic-field dependence of the specific heats of V3Si and LuNi2B2C at a fixed temperature T=7.5K to demonstrate that DTA techniques also allow for sufficiently precise measurements of absolute values of cp even in the absence of a sharp phase transition. The corresponding data for V3Si and LuNi2B2C are briefly discussed.

description: A particle bounded in a potential with finite range is described by using an $f$-deformed quantum oscillator approach. Finite range of this potential can be considered as a controllable deformation parameter. The non-classical quantum statistical properties of this deformed oscillator can be manipulated by nonlinearities associated to the finite range.

A Study of Violence Use Within a Female Prisoner Population. Exploring the Influence of Experiencing Intimate Partner Violence

Year: 2024
Subjects: classificationCode: 520103
subject: Forensic psychology

description: The aim of the research undertaken, is to explore violence perpetration in a population of female prisoners who have experienced violence from an intimate partner. A sample of 15 women in prison participated in interviews. Reflexive Thematic Analysis was used to analyse data. 

Six main themes represent shared ideas about how participants believe their experience of violence from an intimate partner relates to their own use of violence. The themes are Lack of Safety, Violence and Power Imbalance, Limits and Lack of Options, Low Self-worth, Internal Experience of Violence, and Violence and Identity. 

Findings are discussed in relation to the evidence base. The extent to which traditional violence models fully explain violence used by women in the current study appears to be limited. It is suggested that trauma models may provide a better fit for understanding violence in this sample of women, and that this has implications for assessment, treatment, and care. The complex context within which violence is both experienced and used by women in the current sample, is raised as critical to understanding their behaviour, which also has implications for systems of care and support.

description: We present tunneling measurements of sub-micron metal/insulator/graphene planar tunnel junctions up to room temperature. We observe a gate independent gap, as previously observed only by low temperature STM[Y. Zhang et al., Nat. Phys. 4, 627 (2008)]. No gap appears at temperatures above 150K, which is four times smaller than the theoretically expected $T_{c}$, from the accepted mean field model[T. O. Wehling et al. Phys. Rev. Lett. 101, 216803 (2008)]. We show that taking into account an additional vibrational effect of out-of-plane phonon soft modes the gap may disappear from the measurements at temperatures much lower than the calculated $T_{c}$.

description: BackgroundLight-to-moderate alcohol consumption has been reported to be cardio-protective among apparently healthy individuals; however, it is unclear whether this association is also present in those with disease. To examine the association between alcohol consumption and prognosis in individuals with pre-existing cardiovascular disease (CVD), we conducted a series of meta-analyses of new findings from three large-scale cohorts and existing published studies.MethodsWe assessed alcohol consumption in relation to all-cause mortality, cardiovascular mortality, and subsequent cardiovascular events via de novo analyses of 14,386 patients with a previous myocardial infarction, angina, or stroke in the UK Biobank Study (median follow-up 8.7 years, interquartile range [IQR] 8.0-9.5), involving 1640 deaths and 2950 subsequent events, and 2802 patients and 1257 deaths in 15 waves of the Health Survey for England 1994-2008 and three waves of the Scottish Health Survey 1995, 1998, and 2003 (median follow-up 9.5 years, IQR 5.7-13.0). This was augmented with findings from 12 published studies identified through a systematic review, providing data on 31,235 patients, 5095 deaths, and 1414 subsequent events. To determine the best-fitting dose-response association between alcohol and each outcome in the combined sample of 48,423 patients, models were constructed using fractional polynomial regression, adjusting at least for age, sex, and smoking status.ResultsAlcohol consumption was associated with all assessed outcomes in a J-shaped manner relative to current non-drinkers, with a risk reduction that peaked at 7 g/day (relative risk 0.79, 95% confidence interval 0.73-0.85) for all-cause mortality, 8 g/day (0.73, 0.64-0.83) for cardiovascular mortality and 6 g/day (0.50, 0.26-0.96) for cardiovascular events, and remained significant up to 62, 50, and 15 g/day, respectively. No statistically significant elevated risks were found at higher levels of drinking. In the few studies that excluded former drinkers from the non-drinking reference group, reductions in risk among light-to-moderate drinkers were attenuated.ConclusionsFor secondary prevention of CVD, current drinkers may not need to stop drinking. However, they should be informed that the lowest risk of mortality and having another cardiovascular event is likely to be associated with lower levels of drinking, that is up to approximately 105g (or equivalent to 13 UK units, with one unit equal to half a pint of beer/lager/cider, half a glass of wine, or one measure of spirits) a week.
