description: Smartphone based travel data collection has become an important tool for the analysis of transportation systems. Interest in sharing travel survey data has gained popularity in recent years as "Open Data Initiatives" by governments seek to allow the public to use these data, and hopefully be able to contribute their findings and analysis to the public sphere. The public release of such precise information, particularly location data such as place of residence, opens the risk of privacy violation. At the same time, in order for such data to be useful, as much spatial resolution as possible is desirable for utility in transportation applications and travel demand modeling. This paper evaluates geographic random perturbation methods (i.e. Geo-indistinguishability and the Donut geomask) in protecting the privacy of respondents whose residential location may be published. We measure the performance of location privacy methods, preservation of utility and randomness in the distribution of perturbation distances with varying parameters. It is found that both methods produce distributions of spatial perturbations that conform closely to common probability distributions and as a result, that the original locations can be inferred with little information and a high degree of precision. It is also found that while Achieved K-estimate anonymity increases linearly with desired anonymity for the Donut geomask, Geo-Indistinguishability is highly dependent upon its privacy budget factor (epsilon) and is not very effective at assuring desired Achieved K-estimate anonymity.

description: Die Porenzemente im Marbach-Oolith des Oberen Muschelkalks im Steinbruch Brigachtal-Klengen (Schwarzwald-Baar-Kreis, Baden-Württemberg) wurden näher untersucht. Ziel der Untersuchungen war es, Erkenntnisse über Senkung und Hebung der Gesteine nach deren Ablagerung zu gewinnen und die Entstehung der Porenzemente mit Hilfe eines Senkungs-Hebungsdiagramms in eine logische Abfolge zu bringen. Die meisten der interpartikulären Porenräume, der Intrapartikelporen, moldischen Poren und Schirmporen der Kalksteine wurden im Laufe der Senkung und Hebung von kalzitischen, z.T. auch dolomitischen Zementen verschlossen. Während und nach der Zementation kam es zu Lösungsprozessen, so dass heute im Marbach-Oolith Porosität auftritt. Es kam außerdem zu einer komponentenselektiven Rekristallisation, die eine Deformation der Ooide zur Folge hatte.

description: Flow-based generative models, conceptually attractive due to tractability of both the exact log-likelihood computation and latent-variable inference, and efficiency of both training and sampling, has led to a number of impressive empirical successes and spawned many advanced variants and theoretical investigations. Despite their computational efficiency, the density estimation performance of flow-based generative models significantly falls behind those of state-of-the-art autoregressive models. In this work, we introduce masked convolutional generative flow (MaCow), a simple yet effective architecture of generative flow using masked convolution. By restricting the local connectivity in a small kernel, MaCow enjoys the properties of fast and stable training, and efficient sampling, while achieving significant improvements over Glow for density estimation on standard image benchmarks, considerably narrowing the gap to autoregressive models.

description: Background: The widespread use of electronic health records (EHRs) has led to a growing number of large routine primary care data collection projects globally, making these records a valuable resource for health services and epidemiological and clinical research. This scoping review aims to comprehensively assess and compare strengths and limitations of all German primary care data collection projects and relevant research publications that extract data directly from practice management systems (PMS). Methods: A literature search was conducted in the electronic databases in May 2021 and in June 2022. The search string included terms related to general practice, routine data, and Germany. The retrieved studies were classified as applied studies and methodological studies, and categorised by type of research, subject area, sample of publications, disease category, or main medication analysed. Results: A total of 962 references were identified, with 241 studies included from six German projects in which databases are populated by EHRs from PMS. The projects exhibited significant heterogeneity in terms of size, data collection methods, and variables collected. The majority of the applied studies (n = 205, 85%) originated from one database with a primary focus on pharmacoepidemiological topics (n = 127, 52%) including prescription patterns (n = 68, 28%) and studies about treatment outcomes, compliance, and treatment effectiveness (n = 34, 14%). Epidemiological studies (n = 77, 32%) mainly focused on incidence and prevalence studies (n = 41, 17%) and risk and comorbidity analysis studies (n = 31, 12%). Only 10% (n = 23) of studies were in the field of health services research, such as hospitalisation. Conclusion: The development and durability of primary care data collection projects in Germany is hindered by insufficient public funding, technical issues of data extraction, and strict data protection regulations. There is a need for further research and collaboration to improve the usability of EHRs for health services and research.

description: The advancement of concrete 3D printing (C3DP) technology has revolutionized the construction industry, offering unique opportunities for innovation and efficiency. At the heart of this process lies a comprehensive digital chain that integrates various stages, from initial design to post-processing. This article provides an overview of this digital chain, explaining each crucial step. The chain begins with design, utilizing Design for Additive Manufacturing (DFAM) concept and parametric modeling to create optimized structures. Path generation follows, determining the precise toolpath for extruding concrete layers. Simulations, both numerical and analytical, ensure the design's integrity and feasibility. Several articles have addressed parametric modeling, process and numerical simulation, and the post-processing phase. However, none has proposed an updated methodology for the workflow. This study aims to propose a robust digital chain for C3DP technology, using one platform (3Dexperience) and seamless data transfer between applications. These steps provide insights into the structural performance of printed components, enabling necessary adjustments and optimizations. In essence, the digital chain coordinates a seamless workflow that transforms digital designs into concrete structures, unlocking the full potential of C3DP and paving the way for innovative and efficient construction.

description: Mutations in tumor protein p53 play an important role in many human cancers, they are observed in about 50% of all tumors. p53 mutants cause various changes in cellular behavior and function. Accurate computational prediction of the mutant roles can help in clinical decision making for the affected patients. Structure-based prediction of thermodynamic stability, activity, and disease potential of protein mutants are frequently used in the analysis of structure-function relationships in proteins. One of the major challenges of this approach is caused by ambiguities in the structures of investigated proteins, e.g., when multiple structures are available or when the structures are partial. The effects of such ambiguities are investigated using the example of p53 protein. Structure based machine learning models were applied to predict changes in thermodynamic stability of p53 mutants using several different experimental and modeled protein structures. The results show that while structural ambiguities may affect the performance of structure-based function prediction models, the overall function predictions may be correct even when the structure quality is low. This finding has significant implications for using function prediction in the clinically relevant areas, where high quality structures of proteins of interest are frequently unavailable.

description: It is shown that the polarization of hyperons observed in high energy collisions using unpolarized hadron beams and unpolarized nucleon or nuclear targets is closely related to the left-right asymmetries observed in single spin inclusive hadron production processes. The relationship is most obvious for the production of the hyperons which have only one common valence quark with the projectile. Examples of this kind are given. Further implications of the existence of large polarization for hyperon which has two valence quarks in common with the projectile and their consequences are discussed. A comparison with the available data is made. Further tests are suggested.

description: Background: Catheter ablation has become one of the main treatment strategies in patients with premature ventricular complexes (PVC). The successful mapping and ablation can be performed with an ablation catheter without additional diagnostic catheters. Hypothesis: We hypothesize that using a single catheter for PVC ablation may decrease complications, procedure time, and fluoroscopy exposure while maintaining comparable success rates. Methods: Sixty-nine consecutive patients with PVC were treated with a single catheter approach compared to a historical cohort, in which a conventional setup was used. Propensity score matching was conducted with a 1:1 ratio. Outcome parameters included acute procedural success with elimination of all premature ventricular contractions after catheter ablation, procedural data as well as complication rates. Results: Patients treated with a single catheter approach had shorter total procedure (60 minutes [IQR: 47,5–69,0 minutes] vs. 90 minutes [IQR 60–120 minutes]; p = 0.001) and fluoroscopy times (218 seconds [IQR: 110,5–446 seconds] vs. 310 seconds [IQR 190–640 seconds]; p = 0.012), which consecutively leads to a reduction of radiation exposure signified by a lower dose area product (155 cGycm² [IQR 74.4–334.5 cGycm²] vs. 368.4 cGycm² [IQR: 126–905.4 cGycm²]; p value 0.009). Acute procedural success rates were comparable in both groups (54 [84.3%] in the single catheter approach group and 58 [90.6%] in the conventional group; p: 0.287). Conclusion: A single catheter approach for the treatment of PVC is associated with a reduction of procedure- and fluoroscopy time, as well as a lesser radiation exposure, while maintaining equivalent acute success and complication rates compared with a conventionally used catheter setup.

description: The fluid species composition plays a vital role in the wall heat transfer prediction and can be significantly impacted by non-adiabatic effects in the vicinity of cooled wall structures. This research work presents an approach to incorporate the underlying physical impact of a temperature dependency in the chemical reaction rates into the flamelet combustion modeling concept. By evaluating the local Damkoehler number, the newly developed methodology dynamically switches between reactive and frozen chemistry to model the regime of slow kinetic processes. It is validated against finite rate simulations for three 2D test cases subjected to a thermal wall boundary condition.

description: The noncritical $D=4$ $W_3$ string is a model of $W_3$ gravity coupled to two free scalar fields. In this paper we discuss its BRST quantization in direct analogy with that of the $D=2$ (Virasoro) string. In particular, we calculate the physical spectrum as a problem in BRST cohomology. The corresponding operator cohomology forms a BV-algebra. We model this BV-algebra on that of the polyderivations of a commutative ring on six variables with a quadratic constraint, or, equivalently, on the BV-algebra of (polynomial) polyvector fields on the base affine space of $SL(3,C)$. In this paper we attempt to present a complete summary of the progress made in these studies. [...]

description: We report a performance comparison of Zr, Bi, Ti, and Ga as metal contacts on solution-grown CsPbBr3 single-crystal gamma-ray detectors. The same CsPbBr3 single crystal was repeatedly deposited with different metal contacts for the evaluation of gamma spectral performance to eliminate crystal-to-crystal variation. Leakage current as low as 2-3 nA at-200 V with detector thickness 2-3 mm was consistently achieved with Zr, Bi, Ti, and Ga as Schottky contact metal, which is comparable to the leakage current level of a commercial cadmium zinc telluride (CZT) detector. Gamma energy spectra with a prominent photopeak at 662 keV were consistently acquired with all studied metal contacts. The best resolution at 662 keV is 11% with a peak-to-Compton valley ratio of 2, indicating an improved spectrum shape than previous results. Through Americium-241 (241Am) alpha spectra acquisition, the hole mobility of the CsPbBr3 single crystal is evaluated to be 1.78 cm2 V-1 s-1. We also discussed issues related with the CsPbBr3 gamma detector architecture and interface layers, commonly encountered during CsPbBr3 gamma detector fabrication, that is, impact of electron/hole transport layer and surface oxide layer on gamma detector spectral performance, comparison of different metal-perovskite-metal structures. The persistent CsPbBr3 gamma spectral performance marks the good reproducibility of CsPbBr3 gamma detectors, further enabling CsPbBr3 detector field applications.

description: KNO3 -Sorbitol (KNSB) is a simple, cheap and safe solid propellant that is used extensively in the student and amateur rocketry communities. During Ballistic Evaluation Motor (BEM) tests with different propellant compositions it was found that ignition was not achieved with fine KNO3 . This prompted the design of a laser ignition study to investigate the KNSB combustion behaviour. Propellant samples with varying compositions were ignited with a 1064 nm laser. Samples with a fine particle distribution and surfactant showed a different flame structure, and one sample extinguished. Findings were used to improve the fine composition, which led to successful firings.

description: In the frame of the LYRA Program, funded by the Italian Space Agency, the LM-10-MIRA engine has been successfully tested. The engine has a vacuum thrust of 10-tons and has been developed by a joint Avio-KBKhA propulsion team in the frame of a dedicated ASI-Roscosmos inter-agencies agreement. After the experimental test campaign, further improvement for flight application have been identified, including the improvement of the efficiency and new technologies for of injector head manufacturing. The `lesson learned\' allowed ASI to promote further activities in collaboration with Avio. In particular, two main activities have been developed, the first one aimed to reduce the methane line pressure drop and the second one related to the optimization of the methane/oxygen interfaces. The results have been implemented on a subscale version of the injector head. The present work describes the improvements obtained and confirmed by the results of the subscale experimental test campaign.

description: Thrusters\' plume interactions with spacecraft can have a very important impact in their different subsystems (thermal, power generation, GNC). Moreover, with the current trend of increasing the optical instruments, it is even more relevant to study its effects as a source of heat and contamination on the exposed components. It is also always relevant to determine the forces and torques that the impingement can induce on the overall spacecraft. Therefore, prediction of the plume impingement effects during the design phases is becoming more relevant in order to find the best geometrical system configuration and components accommodation. There already exist different advanced tools based on computational fluid dynamics (CFD) and Direct Simulation Monte Carlo (DSMC) methods that allow performing detailed analysis. However, they are complex and time consuming, and could not be the best option to use during the preliminary design phases but in final phases to consolidate the results. In early stages of the design, there is needed to multiple configurations in a very short time to adapt the design to the constraints imposed by all the subsystems and several trade-offs need to be performed. The present work intends to provide an efficient alternative approach that allows evaluating the plume impingement phenomenon in early design phases. An in-house developed tool implemented in MATLAB(R) is presented. This tool is based on the combination of different classical source flow methods (SimonsBoynton and Mayer-Hermel-Rogers), and free-molecular flow interactions with the surfaces. It allows performing fast and easy evaluations of the configuration changes in the spacecraft. Based on the detailed plume flow results provided by the thrusters\' supplier, a set of models\' parameters correction is proposed to ensure the fit of the employed source model in order to have accurate results at a very low computational cost. The developed tool has been employed in the design of Proba-3 ESA\'s IOD mission to determine the heat fluxes, contamination, power loss and disturbance forces of each spacecraft configuration allowing to evaluate the impact of the changes in the thrusters\' orientations and positions and external elements.

description: We apply a gauge invariant formulation of Wilson Renormalization Group (RG) to the computation of the Debye and transverse gluon masses in pure gauge SU(N) at high temperature. Following the Hard Thermal Loop effective field theory as a guideline, we develop an approximation scheme to the exact evolution equations. The Debye mass receives sizable corrections compared to the leading order perturbative result, mainly due to the infrared singular behavior in the transverse gluon sector. A non-vanishing mass for the transverse gluons is found, which acts as an infrared regulator though not efficiently enough as to restore the validity of perturbation theory. Indeed, discussing the role of higher dimensional operators, we show that the gauge coupling for the transverse modes typically flows to non-perturbative values unless extremely high temperatures are reached. After comparing our results with recent lattice simulations, we comment on the possibility of using this formulation of the RG as a tool to construct an effective field theory for the non-perturbative, long wavelength, transverse modes.

description: The economical relevance of Reusable Launch Vehicles (RLV) highly depends on the Maintenance, Repair and Overhaul (MRO) costs, which should be kept as low as possible. For that purpose, providing efficient solutions for assessing the health state of a launcher is a crucial matter. This work aims at proposing a new paradigm for the assessment of the health of wires inside a launcher. After a description of the big picture of such a supervision system, its viability is examined in detail, considering all mission constraints.

description: Spin-orbit coupled (SOC) light fields with spatially inhomogeneous polarization have attracted increasing research interest within the optical community. In particular, owing to their spin-dependent phase and spatial structures, many nonlinear optical phenomena which we have been familiar with up to now are being re-examined, hence a revival of research in nonlinear optics. To fully investigate this topic, knowledge on how the topological structure of the light field evolves is necessary, but, as yet, there are few studies that address the structural evolution of the light field. Here, for the first time, we present a universal approach for theoretical tomographic treatment of the structural evolution of SOC light in nonlinear optics processes. Based on a Gedanken vector second harmonic generation, a fine-grained slice of evolving SOC light in a nonlinear interaction and the following diffraction propagation are studied theoretically and verified experimentally, and which at the same time reveal several interesting phenomena. The approach provides a useful tool for enhancing our capability to obtain a more nuanced understanding of vector nonlinear optics, and sets a foundation for further broad-based studies in nonlinear systems.

description: Over the past two decades, anti-vaccine activism in the USA has evolved from a fringe subculture into an increasingly well organised, networked movement with important repercussions for public health. The COVID-19 pandemic has exacerbated this evolution and magnified the reach of vaccine misinformation. Anti-vaccine activists, who for many years spoke primarily to niche communities hesitant about childhood vaccinations, have used traditional and social media to amplify vaccine-related mistruths about COVID-19 vaccines while also targeting historically marginalised racial and ethnic communities. These efforts contributed to COVID-19 vaccine hesitancy and expanded the movement, with early indications suggesting that this hesitancy could now also be increasing hesitancy that existed pre-pandemic towards other vaccines. It is important to understand the implications of this recent evolution of anti-vaccine activism on vaccination uptake and the promotion of sound public health strategies. In this Viewpoint, we summarise the latest developments in US-based anti-vaccine activism and propose strategies for confronting them.
Entropic measure of spatial disorder for systems of finite-sized objects

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We consider the relative configurational entropy per cell S_Delta as a measure of the degree of spatial disorder for systems of finite-sized objects. It is highly sensitive to deviations from the most spatially ordered reference configuration of the objects. When applied to a given binary image it provides the quantitatively correct results in comparison to its point object version. On examples of simple cluster configurations, two-dimensional Sierpinski carpets and population of interacting particles, the behaviour of S_Delta is compared with the normalized information entropy H' introduced by Van Siclen [Phys. Rev. E 56, (1997) 5211]. For the latter example, the additional middle-scale features revealed by our measure may indicate for the traces of self-similar structure of the weakly ramified clusters. In the thermodynamic limit, the formula for S_Delta is also given.

The seeds of supermassive black holes and the role of local radiation and metal spreading

description: We present cosmological hydrodynamical simulations including atomic and molecular non-equilibrium chemistry, multi-frequency radiative transfer (0.7-100 eV sampled over 150 frequency bins) and stellar population evolution to investigate the host candidates of the seeds of supermassive black holes coming from direct collapse of gas in primordial haloes (direct-collapse black holes, DCBHs). We consistently address the role played by atomic and molecular cooling, stellar radiation and metal spreading of C, N, O, Ne, Mg, Si, S, Ca, Fe, etc. from primordial sources, as well as their implications for nearby quiescent proto-galaxies under different assumptions for early source emissivity, initial mass function and metal yields. We find that putative DCBH host candidates need powerful primordial stellar generations, since common solar-like stars and hot OB-type stars are neither able to determine the conditions for direct collapse nor capable of building up a dissociating Lyman-Werner background radiation field. Thermal and molecular features of the identified DCBH host candidates in the scenario with very massive primordial stars seem favourable, with illuminating Lyman-Werner intensities featuring values of 1-50 J21. Nevertheless, additional non-linear processes, such as merger events, substructure formation, rotational motions and photo-evaporation, should inhibit pure DCBH formation in 2/3 of the cases. Local turbulence may delay gas direct collapse almost irrespectively from other environmental conditions. The impact of large Lyman-Werner fluxes at distances smaller than 5 kpc is severely limited by metal pollution.
