description: The PATOF project builds on work ongoing at MAMI particle physics experiment A4. It produced a stream of valuable data for many years which already released scientific output of high quality and still provides a solid basis for future publications. Here, we report from our approach to make the data hoard of a dismounted project sustainable and publishable according to the FAIR principles which, finally, would make the data intelligible to, both, humans and machines. In addition to a complex central detector system recording electrons after their scattering off nuclear targets, several auxiliary systems were used to record parameters like beam position or environmental and slow-control data. The A4 data set consists of about 100 TB and 300 million files of different types (hierarchical folder structure and file format with minimal metadata provided create vague context). Recent work with consulting support from the HMC hub “Matter” helped to identify problems and potential solutions for a FAIRification of A4 data. We would now like to go beyond the support we can get from the hub and build a full “FAIR Metadata Factory” that can be used across the research field and beyond. The focus of PATOF is on making the data of A4 (and in the future of ALPS II, PRIMA, P2, and LUXE) fully publicly available. The project proposes to apply expertise in FAIR data management gained in PUNCH experiments to other disciplines. The results - including the generalisation of the FAIR Metadata Factory - will be openly available, with the perspective of establishing a “living cookbook” useful for any data project. PATOF will serve as a catalyst by having good connections to other research fields, to the NFDI, and also to related HMC applications.

description: Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive solid malignancies with poor survival rates. Only 20% of the patients are eligible for R0-surgical resection, presenting with early relapses, mainly in the liver. PDAC patients with hepatic metastases have a worse outcome compared to patients with metastases at other sites. Early detection of hepatic spread bears the potential to improve patient outcomes. Thus, this study sought for serum-based perioperative biomarkers allowing discrimination of early (EHMS ≤ 12 months) and late hepatic metastatic spread (LHMS > 12 months). Serum samples from 83 resectable PDAC patients were divided into EHMS and LHMS and analyzed for levels of inflammatory mediators by LEGENDplexTM, which was validated and extended by Olink® analysis. CA19-9 serum levels served as control. Results were correlated with clinicopathological data. While serum CA19-9 levels were comparable, Olink® analysis confirmed distinct differences between both groups. It revealed significantly elevated levels of factors involved in chemotaxis and migration of immune cells, immune activity, and cell growth in serum of LHMS-patients. Overall, Olink® analysis identified a comprehensive biomarker panel in serum of PDAC patients that could provide the basis for predicting LHMS. However, further studies with larger cohorts are required for its clinical translation.

description: Adult playfulness describes individual differences in (re)framing everyday situations as personally interesting, and/or entertaining, and/or intellectually stimulating. We aimed at extending initial evidence on the interconnectedness between language use and adult playfulness by asking 264 participants (M = 26.5 years, SD = 9.7; 66.7% women) to provide written descriptions of their understanding of playfulness (mean length: 30.6 words; SD = 24.1) and collected self-reports of their playfulness. We used the Linguistic Inquiry and Word Count methodology to quantitatively analyze the language use in these descriptions and tested the associations with individual differences in participants’ age, gender, and playfulness. While higher expressions in all measures of playfulness did go along with writing more content when describing playfulness (rs = 0.13 to 0.25), facet-wise analyses revealed differential findings (e.g., intellectual playfulness relates to using words describing cognitive processes); but the effects were small. We found that being a women and younger age were related to writing longer texts (0.13 ≤ rs ≤ 0.24), and we discovered additional associations between certain LIWC categories and age and gender. Our study expands the knowledge about adult playfulness and its manifestations in natural language use. We embed our findings into previous research and discuss limitations and potential approaches for replication studies.

title: The Chemodynamic-Age Structure of the Local Population of Low-Mass Stars
Creators: name: Medan, Ilija
Publisher: name: Georgia State University
Year: 2024

description:
High-dimensional datatsets of local stars are now available thanks to large surveys. These data are useful for Galactic archaeology, which seeks to understand the history of the Milky Way. These studies predominantly utilize more massive stars, but low-mass stars dominate in the Galaxy and would provide the highest-resolution view of the local chemo-dynamical- age structure. Here we construct the novel methodologies needed to accomplish this to better constrain Milky Way models. First, we construct our dataset by developing a Bayesian cross-matching method that we apply to ~6 million high proper motion Gaia sources. The resulting catalog has a marginally higher match rate than internal Gaia DR2 matches and a significant improvement for Pan-STARRS (~20.8% to ~99.8% within the survey footprint). With these data, we develop a photometric-metallicity relationship that has an average precision of 0.12 dex for dwarfs with 3500 K and is largely free of systematic errors present in past studies due to the removal of unresolved binaries in this work. As a result, we devoted time to developing methods to detect binaries without using astrometry. Here we present this method, which would increase the number of local (d<200 >pc) low angular separation binaries by ~91%, and the results of a speckle imaging campaign. Finally, we combined the astrometric and photometric-metallicity data to get a detailed view of the chemo-dynamic-age structure of ~250,000 low-mass stars. Here we observe trends in metallicity and vertical velocity dispersion hypothesized to be due to differences in mean age. To test this, we develop a method to estimate the age distribution of sub-populations of stars using GALAH defined probability density functions of W vs. [M/H]. We estimate the probable age distribution for regions in the kinematic plane, where we see significant sub-structure; high angular momentum streams have higher concentrations of younger stars (Gyr), while the Hercules streams are dominated by older stars (8-10 Gyr). With these data, we preview a method for constraining test particle simulations to determine Galactic potential parameters. The methodologies presented here demonstrate the power of low-mass stars and how they can be used to better understand our Galaxy.

Datafication

description: Eingebettet in die Datafizierung sämtlicher gesellschaftlicher Bereiche, befinden sich auch die Geschichtswissenschaften und historisch arbeitenden Wissenschaften in einem rapiden, epochalem Wandel. Datafizierung betont dabei den epistemologischen und ontologischen Kulturwandel von einer Welt in der Daten ein eng definierter Teil des Outputs von Forschungsprozessen waren, zu einem neuen Status Quo in dem sämtliche Aspekte von Forschungsprozessen jeweils bereits durch Informations- und Kommunikationstechnologien (ICT) sowie Algorithmen computationel vermittelt sind. Eine solcherart gelagerte Datafizierung im weitere Sinn, in der menschliche Handlungsmacht (agency) und algorithmisches Handeln (actions) intrinsisch miteinander verflochten sind, setzt eine Datafizierung im engeren Sinn voraus, bei der durch einen Akt der Modellierung die Wirklichkeit auf diskrete Aussagen für die Verarbeitung durch Computer reduziert wird.

Das seit 2023 arbeitenden NFDI-(Nationale Forschungsdateninitiative)Konsortium 4Memory fokussiert auf die spezifischen Herausforderungen der Datafizierung für jegliche Art von historischen Fragestellungen und Kontexte, die einer historischen Kontextualisierung bedürfen. Aus unserem Verständnis der Datafizierung folgt auch, dass diese Herausforderungen nicht auf das Forschungsdatenmanagement (FDM) verengt werden können, sondern dass es für eine zeitgenössische Geschichtswissenschaft einer umfassenden Datenkultur bedarf. Im weiteren Sinne verstehen wir darunter eine Fachkultur, bei der (Forschungs-)daten und datengetriebener Methoden ein integraler Bestandteil wissenschaftlichen Arbeitens sind, die Arbeit mit und an Daten also nicht mehr als ein “netter” aber entbehrlicher Appendix zum “eigentlichen” Forschungsprozess verstanden wird. Daher benötigen wir auch eine gelebte alltägliche Datenkultur von Praktiken und Verantwortlichkeiten (auch rechtlich und ethisch) im Umgang mit Forschungsdaten bei deren Erzeugung, Bereitstellung und Nutzung mit Hilfe von computationellen Methoden und Werkzeugen.

Die Stärkung einer solchen Datenkultur ist das Ziel der von der Humboldt-Universität zu Berlin und dem Verband der Historikerinnen und Historiker Deutschlands verantwortete Task Area “Data Culture” des NFDI4Memory.

In unserem Vortrag stellen wir unsere Ansätze und konkreten Maßnahmen für die Förderung einer gelebten Datenkultur am Beispiel eines konkreten historischen Forschungsprozesses vor und zur Diskussion.
title: Modelling of Airwake Hazards for Helicopter Flight Simulation
Creators: name: Henriquez Huecas, Sergio
Publisher: name: University of Liverpool Repository
Year: 2023

description: This thesis summarises the work performed in the use of flight simulation to assess the impact of wake encounters and turbulence on the safety of helicopter operations. An initial literature search is presented, revealing a lack of previous research regarding the impact of wind turbine wakes on helicopter operations and a lack of accurate and easy to implement modelling tools for the assessment of the impact of turbulence on rotorcraft handling. The work is divided in two main parts: In the first part, following a literature review, results of flight simulation tests representing the accidental crossing of a wind turbine wake by a helicopter are presented. Encounters are of a ‘mild’ severity, flight safety was not compromised and resulted mainly in excursions in the yaw axis and deviations in roll. The pilot workload required in the recovery of from the initial encounter was strongly related to the aircraft’s handling qualities, especially yaw to pitch and yaw to roll cross couplings. The second part of the thesis details the development and implementation of a new turbulence modelling method for flight simulation. The model is based on an adaptation of a synthetic eddy method (SEM). It generates a random turbulence field surrounding the aircraft by filling a control volume with turbulence generating eddies which are displaced by ambient flow; this is the first time this type of modelling has been implemented in real-time piloted flight simulation. The induced turbulence automatically cross correlates disturbances across all aircraft elements and can be adjusted by changing strength, shape and size of eddies and combining series of eddies with different properties. Average frequency of the induced turbulence is proportional to the cube root of the number of eddies; increasing the frequency results in increased computational costs. Nevertheless, the SEM turbulence generator can produce real time disturbances within the 0.1 – 1Hz frequency range which has the most impact on pilot workload. Offline and piloted simulation was used to evaluate the model and compare against a precomputed wake using a Mann turbulence model. Results show that SEM induced turbulence can impact handling in similar manners as the precomputed wake, while offering random turbulence in real time.

In particular, we deduce that over an algebraically closed field of characteristic zero, all classes of H^2_ét(M,G_m) come from Azumaya algebras.

description: Tidal interactions between Planet and its satellites are known to be the main phenomena, which are determining the orbital evolution of the satellites. We suggest in the current research to take into consideration the additional well-known effect of differential rotation which obviously takes place in the gaseous or fluid convection zone of primary giant Planet (indeed, the aforementioned effect exists even not depending on the orbital evolution of satellites around host Planet). Nevertheless, estimations for the contribution of the aforementioned effect of differential rotation in the Uranus system (including all its most massive satellites) let us exclude using such effect from calculations of mutual evolution of the eccentricity e along with the semi-major axis a for all satellites of Uranus (Planet of ice-type). It means that the Uranus can be considered in the analytic exploration of governing equations as to be the appropriate candidate for applying the modern ansatz [Efroimsky, 2015] (tidal dissipation effect depending on the tidal-flexure frequency) in regard to estimations of eccentricity e along with semi-major axis a for satellites of Uranus. We can see from the results of calculations in Section 3 that the combined system of governing equations (in the sense of combined contributions to the tidal dissipation from Uranus + from satellite) yields the really observed magnitudes of decelerations for semi-major axises of all the satellites of Uranus. Meanwhile, internal heat generation effects in the satellites (due to tidal dissipation effect) are much more than those which definitely take place in the Uranus, excepting the case of Ariel.

description: We prove explicit rationality-results for Asai- $L$-functions, $L^S(s,Π',{\rm As}^\pm)$, and Rankin-Selberg $L$-functions, $L^S(s,Π\timesΠ')$, over arbitrary CM-fields $F$, relating critical values to explicit powers of $(2πi)$. Besides determining the contribution of archimedean zeta-integrals to our formulas as concrete powers of $(2πi)$, it is one of the advantages of our approach, that it applies to very general non-cuspidal isobaric automorphic representations $Π'$ of ${\rm GL}_n(\mathbb A_F)$. As an application, this enables us to establish a certain algebraic version of the Gan--Gross--Prasad conjecture, as refined by N.\ Harris, for totally definite unitary groups. As another application we obtain a generalization of a result of Harder--Raghuram on quotients of consecutive critical values, proved by them for totally real fields, and achieved here for arbitrary CM-fields $F$ and pairs $(Π,Π')$ of relative rank one.

description: We systematically review some standard issues and also the latest developments of modified gravity in cosmology, emphasizing on inflation, bouncing cosmology and late-time acceleration era. Particularly, we present the formalism of standard modified gravity theory representatives, like $F(R)$, $F(\mathcal{G})$ and $F(T)$ gravity theories, but also several alternative theoretical proposals which appeared in the literature during the last decade. We emphasize on the formalism developed for these theories and we explain how these theories can be considered as viable descriptions for our Universe. Using these theories, we present how a viable inflationary era can be produced in the context of these theories, with the viability being justified if compatibility with the latest observational data is achieved. Also we demonstrate how bouncing cosmologies can actually be described by these theories. Moreover, we systematically discuss several qualitative features of the dark energy era by using the modified gravity formalism, and also we critically discuss how a unified description of inflation with dark energy era can be described by solely using the modified gravity framework. Finally, we also discuss some astrophysical solutions in the context of modified gravity, and several qualitative features of these solutions. The aim of this review is to gather the different modified gravity techniques and form a virtual modified gravity "toolbox", which will contain all the necessary information on inflation, dark energy and bouncing cosmologies in the context of the various forms of modified gravity.

title: Shining a Light on Brain Cancer: Utilising Photodynamic Therapy in the Treatment of Glioblastoma
titleType: Other
Creators: name: Nicely, Lynden
Publisher: name: University of Dundee
Year: 2023

description: Photo diagnosis is used intraoperatively to identify glioblastoma (GBM) tumour and achieve a greater extent of resection. Patients are given a ‘pink drink’ of 5-aminolevulinic acid (5ALA), a photosensitiser, which is preferentially taken up by cancer cells and fluoresces under certain light frequencies. It has been shown that the use of photosensitisers and light in this process may cause cell death, encouraging the investigation of photodynamic therapy as a potential treatment for GBM.

While the potential of photodynamic therapy (PDT) as a diagnostic option is evolving, PDT’s progress in neuro-oncology remains in its infancy. Although reactive oxygen species (ROS) generation has been proposed to be an important factor contributing to cell death in PDT treatment, limited evidence is available to confirm this. We aim to establish the mechanism of cell death observed in primary GBM 2D and 3D cells upon exposure to light and photosensitiser and confirm the efficacy of PDT therapy using an in vitro cell culture system.

Primary patient derived glioma cell lines and 3D stem neurospheres were exposed to 630nm LED laser irradiation with the use of 5-ALA photosensitiser. Cell kill was assessed using microscopy and an MTS cell viability assay quantified by a 96-well Tecan plate reader. N- acetyl-L-Cysteine (NAC), L-Buthionine-sulfoximine (BSO) and assays using CellROX photosensitiser were used to investigate ROS as a mechanism of cell kill.

Results show that cell death was not caused by 5ALA and irradiation alone, however, the combined effect of the two incurred cell death in cell lines tested with evidence of ROS playing a role in the mechanism of cell death.

At the same time, the properties of knowledge obtained from only a finite subset of this body are described by modal logic S4. The main technical result is a sound and complete bi-modal logical system that describes properties of these two modalities and their interplay.

description: Harnessing the properties of vortices in superconductors is crucial for fundamental science and technological applications; thus, it has been an ongoing goal to locally probe and control vortices. Here, we use a scanning probe technique that enables studies of vortex dynamics in superconducting systems by leveraging the resonant behavior of a raster-scanned, magnetic-tipped cantilever. This experimental setup allows us to image and control vortices, as well as extract key energy scales of the vortex interactions. Applying this technique to lattices of superconductor island arrays on a metal, we obtain a variety of striking spatial patterns that encode information about the energy landscape for vortices in the system. We interpret these patterns in terms of local vortex dynamics and extract the relative strengths of the characteristic energy scales in the system, such as the vortex-magnetic field and vortex-vortex interaction strengths, as well as the vortex chemical potential. We also demonstrate that the relative strengths of the interactions can be tuned and show how these interactions shift with an applied bias. The high degree of tunability and local nature of such vortex imaging and control not only enable new understanding of vortex interactions, but also have potential applications in more complex systems such as those relevant to quantum computing.

description: Near neighbor search (NNS) is a powerful abstraction for data access; however, data indexing is troublesome even for approximate indexes. For intrinsically high-dimensional data, high-quality fast searches demand either indexes with impractically large memory usage or preprocessing time. In this paper, we introduce an algorithm to solve a nearest-neighbor query $q$ by minimizing a kernel function defined by the distance from $q$ to each object in the database. The minimization is performed using metaheuristics to solve the problem rapidly; even when some methods in the literature use this strategy behind the scenes, our approach is the first one using it explicitly. We also provide two approaches to select edges in the graph's construction stage that limit memory footprint and reduce the number of free parameters simultaneously. We carry out a thorough experimental comparison with state-of-the-art indexes through synthetic and real-world datasets; we found out that our contributions achieve competitive performances regarding speed, accuracy, and memory in almost any of our benchmarks.

description: In this paper, we study the ergodicity of invariant sublinear expectation of sublinear Markovian semigroup. For this, we first develop an ergodic theory of an expectation-preserving map on a sublinear expectation space. Ergodicity is defined as any invariant set either has $0$ capacity itself or its complement has $0$ capacity. We prove, under a general sublinear expectation space setting, the equivalent relation between ergodicity and the corresponding transformation operator having simple eigenvalue $1$, and also with Birkhoff type strong law of large numbers if the sublinear expectation is regular. For sublinear Markov process, we prove that its ergodicity is equivalent to the Markovian semigroup having eigenvalue $1$ and it is simple in the space of bounded measurable functions. As an example we show that $G$-Brownian motion $\{B_t\}_{t\geq 0}$ on the unit circle has an invariant expectation and is ergodic if and only if ${\mathbb E}(-(B_1)^2)<0$. Moreover, it is also proved in this case that the invariant expectation is regular and the canonical stationary process has no mean-uncertainty under the invariant expectation.

description: A key challenge for modern Bayesian statistics is how to perform scalable inference of posterior distributions. To address this challenge, variational Bayes (VB) methods have emerged as a popular alternative to the classical Markov chain Monte Carlo (MCMC) methods. VB methods tend to be faster while achieving comparable predictive performance. However, there are few theoretical results around VB. In this paper, we establish frequentist consistency and asymptotic normality of VB methods. Specifically, we connect VB methods to point estimates based on variational approximations, called frequentist variational approximations, and we use the connection to prove a variational Bernstein-von Mises theorem. The theorem leverages the theoretical characterizations of frequentist variational approximations to understand asymptotic properties of VB. In summary, we prove that (1) the VB posterior converges to the Kullback-Leibler (KL) minimizer of a normal distribution, centered at the truth and (2) the corresponding variational expectation of the parameter is consistent and asymptotically normal. As applications of the theorem, we derive asymptotic properties of VB posteriors in Bayesian mixture models, Bayesian generalized linear mixed models, and Bayesian stochastic block models. We conduct a simulation study to illustrate these theoretical results.

description: Terahertz emission spectroscopy of ultrathin multilayers of magnetic and heavy metals has recently attracted much interest. This method not only provides fundamental insights into photoinduced spin transport and spin-orbit interaction at highest frequencies but has also paved the way to applications such as efficient and ultrabroadband emitters of terahertz electromagnetic radiation. So far, predominantly standard ferromagnetic materials have been exploited. Here, by introducing a suitable figure of merit, we systematically compare the strength of terahertz emission from X/Pt bilayers with X being a complex ferro-, ferri- and antiferromagnetic metal, that is, dysprosium cobalt (DyCo$_5$), gadolinium iron (Gd$_{24}$Fe$_{76}$), Magnetite (Fe$_3$O$_4$) and iron rhodium (FeRh). We find that the performance in terms of spin-current generation not only depends on the spin polarization of the magnet's conduction electrons but also on the specific interface conditions, thereby suggesting terahertz emission spectroscopy to be a highly surface-sensitive technique. In general, our results are relevant for all applications that rely on the optical generation of ultrafast spin currents in spintronic metallic multilayers.
Strain-induced polar discontinuities in two-dimensional materials from combined first-principles and Schrödinger-Poisson simulations

description: The local application of mechanical stress in piezoelectric materials gives rise to boundaries across which the electric polarization changes. Polarization charges appear along such polar discontinuities and the ensuing electric fields drive a charge reconstruction with the accumulation of free carriers at the boundaries. This is particularly relevant for two-dimensional materials that can sustain very large strains and display record piezoelectric responses. Here we show by first-principles simulations the emergence of one-dimensional wires of free electrons and holes along strain interfaces, taking SnSe as a paradigmatic material. We complement this by developing a Schrödinger-Poisson approach specifically designed for two-dimensional materials that it is able to reproduce the ab-initio results and also to extend them to regimes of parameters and system sizes that would be unaffordable in first principles calculations. This model allows us to assess the degree of tunability for the free charge in the wires coming from strain values and profiles, and to obtain the critical size at which the interfaces start to be metallic.

description: Mild traumatic brain injury (MTBI) is a global health concern contributing to morbidity and disability, with pediatric patients facing unique vulnerabilities due to developmental and psychosocial factors. The impact of MTBI is exacerbated in rural and underserved communities, where limited healthcare access hampers effective management and optimal outcomes. Addressing current gaps in care through a comprehensive knowledge update is essential for the development of targeted solutions.

To provide a thorough understanding of the subject, a comprehensive search was conducted on the National Library of Medicine PubMed database using specific search terms related to MTBI, rural/underserved areas, and pediatric populations up to December 2022. Fifteen articles, not covered in previous reviews, were identified and categorized into four key topics: epidemiology, care practices, socioeconomic factors, and the role of telehealth.

Incidence rates of pediatric MTBI are notably higher in rural regions, among minorities, and in children aged 0–4 years, with a concerning upward trend. Healthcare utilization patterns in rural areas favor emergency departments for initial injury assessment, emphasizing the need for tailored management guidelines in resource-constrained settings. A consensus challenge in rural communities is the lack of recognition of the severity of MTBI, hindering timely care provision. Additionally, low parental education and income are associated with decreased MTBI knowledge and poorer outcomes. Telehealth protocols show promise in improving care delivery, particularly in triage/consultation and rehabilitation, thus addressing the geographic and financial barriers to healthcare access in rural and remote settings.

Pediatric MTBI patients in rural and underserved regions face heightened risks of injury, compounded by geographic and financial healthcare barriers, resulting in suboptimal outcomes. Globally, under-reporting of MTBI has impeded a comprehensive understanding of its epidemiology. To address these challenges, ongoing education initiatives targeted at rural caregivers, schools, and low-income populations are crucial for enhancing community awareness. Furthermore, the judicious inclusion of telehealth in triage and treatment protocols holds significant potential for bridging gaps in care delivery across diverse acuity settings.

description: We perform a global Bayesian analysis of currently available neutrino data, putting data from oscillation experiments, neutrinoless double beta decay ($0νββ$), and precision cosmology on an equal footing. We evaluate the discovery potential of future $0νββ$ experiments and the Bayes factor of the two possible neutrino mass ordering schemes for different prior choices. We show that the indication for normal ordering is still very mild and does not strongly depend on realistic prior assumptions or different combinations of cosmological data sets. We find a wide range for $0νββ$ discovery potential, depending on the absolute neutrino mass scale, mass ordering and achievable background level.
