    Impulsive decision-making predicts the course of substance-related and addictive disorders
    (Technische Universität Dresden, 2018) Kräplin, Anja
    Data and do-files for the analyses presented in the paper "Impulsive decision-making predicts the course of substance-related and addictive disorders" Aims of the analyses: To test whether impulsive decision-making (1) differs between individuals with substance use disorders (SUD) or non-substance-related addictive disorders (ND) and healthy controls and (2) predicts the course of SUD and ND severity after one year. Design of the study: Baseline and one year follow-up of a prospective-longitudinal community study. Setting of the study: Clinical interviews and behavioural tasks in the laboratory. Participants: 338 individuals between age 20 and 26 were selected from a random sample from the registration office files of Dresden, Germany. Participants fulfilled the criteria for one of three groups: SUD, ND, or healthy controls. After one year, we assessed 313 participants again (93%). Measurements: ND and SUD severity were operationalized with number of DSM-5 symptoms (partly modified for ND) and quantity-frequency indices of use. Four tasks were applied to assess independent facets of impulsive decision-making: 1) delay discounting, 2) risk seeking for gains and 3) for losses, and 4) loss aversion.

    Snow tracer - Observation and model simulations for laboratory and field experiments
    (Technische Universität Dresden, 2018-04-06) Binder, Martin
    Application of snowmelt as an active and inexpensive dual isotope groundwater tracer - Stable isotope analysis is widely used in environmental tracer studies, e.g. for groundwater flow and discharge quantification. In this context, this study presents an inexpensive approach for the combined use of deuterium (2H) and oxygen-18 (18O) as active semiartificial groundwater tracers by a direct injection of snowmelt into aquifers. This dual isotope approach takes advantage of isotope signature differences between typical groundwater and precipitation water. Aim of this study is the experimental demonstration on laboratory- and field-scale. For this, two column flow experiments were performed using δ2H and δ18O values of snowmelt for breakthrough detection. The differences of the isotope signature between the snowmelt and groundwater were ∆(δ2H) ≈ 61.0 ‰ and ∆(δ18O) ≈ 8.2 ‰. Breakthrough was observed to be almost congruent to a sodium chloride tracer, indicating conservative transport. The low electrical conductivity (EC) of snowmelt (45 µS/cm, i.e. ∆EC ≈ 486 µS/cm to groundwater) was used as an additional easy-to-measure breakthrough indicator. However, the snowmelt EC breakthrough suffered from a slight retardation due to ion exchange. Based on these results, a push-drift-pull tracer test with snowmelt, additionally labeled with uranine, was realized at the field site Pirna, Germany. In the pull phase, a significant isotopic depletion was observed with peak differences of ∆Peak(δ2H) ≈ 24.2 ‰ and ∆Peak(δ18O) ≈ 3.2 ‰, which equals approx. 40 % of the initial difference. The isotope breakthrough was observed to be almost the same as the breakthrough of uranine indicating conservative behavior, while EC breakthrough was affected by ion exchange again.

    Strain curves measured with different DFOS types and varying spatial resolution by an ODiSI 6108
    (Technische Universität Dresden, 2024-03-15) Herbers, Max
    Based on the principle of coherent optical frequency domain reflectometery (c-OFDR), cracks in concrete structures can be precisely localized and their widths determined due to the high spatial resolution in the sub-millimeter range. However, with longer distributed fiber optic sensors (DFOS) lengths, as is common in structural health monitoring, the spatial resolution is reduced. Experimental studies were carried out to investigate the influence of the spatial resolution on the measurement quality in the area of large strain gradients. Four different DFOS, two robust and two filigree DFOS types, were subsequently installed on a 4 m long reinforced concrete beam. In a displacement controlled 4-point bending test, crack widths of up to 0.5 mm were measured with four different gage pitch (gp).

    Extended Phase-Field Method (XPFM) - Data corresponding to publication: "An enriched phase-field method for the efficient simulation of fracture processes" by Loehnert et al. (2023)
    (Technische Universität Dresden, 2024-04-22) Curosu, Verena
    This dataset contains the numerical values corresponding to the graphs within the scientific (open-access) contribution "An enriched phase-field method for the efficient simulation of fracture processes" by Loehnert et al. (2023) (https://doi.org/10.1007/s00466-023-02285-z). Abstract of Paper: The efficient simulation of complex fracture processes is still a challenging task. In this contribution, an enriched phase-field method for the simulation of 2D fracture processes is presented. It has the potential to drastically reduce computational cost compared to the classical phase-field method (PFM). The method is based on the combination of a phase-field approach with an ansatz transformation for the simulation of fracture processes and an enrichment technique for the displacement field as it is used in the extended finite element method (XFEM) or generalised finite element method (GFEM). This combination allows for the application of significantly coarser meshes than it is possible in PFM while still obtaining accurate solutions. In contrast to classical XFEM / GFEM, the presented method does not require level set techniques or explicit representations of crack geometries, considerably simplifying the simulation of crack initiation, propagation, and coalescence. The efficiency and accuracy of this new method is shown in 2D simulations.

    PGT Prompt Gamma Timing PETsys data for publication at IKTP (PGT)
    (Technische Universität Dresden, 2024-05-14) Novgorodova, Olga; Straessner, Arno; Hentges, Rainer; Glatte, Andreas; Lutz, Benjamin; Roemer, Katja; Teichmann, Thobias; Koegler, Toni
    Proton therapy requires range verification in order to exploit its full potential. One of the most promising approaches is to monitor prompt gamma-rays produced by nuclear interactions of the therapeutic particles in the patient tissues. In our paper, we test PETsys electronics with a detector with a wide energy range from 100 keV to 15 MeV. We tested what time resolution we could achieve as a high time resolution is required to achieve millimetric precision in the proton range. PETsys should survive high count rates and the fraction of pile-up events should be low or separatable. We are investigating a full acceptance approach with increased granularity in order to reduce the size of the scintillators and consequently the count rate per channel. Ideally, we want to stack the scintillators in matrices that require suitable multi-channel photo-multipliers and a fitting acquisition system. Here, we present two geometries of CeBr3 crystals 5 × 5 × 20 mm3 and 10 × 10 × 30 mm3, together with modern silicon photo-multipliers (SiPM) adapted to work with the PETsys TOFPET2 ASIC. The TOFPET2 ASIC was developed for Time-of-Flight Positron Emission Tomography (TOF-PET) applications. Here are our data measured for the publication for time resolution and coincidence time resolution, energy resolution with AmBe source, and dead time studies.

    Amplification of Negative Gas Adsorption in a multivariate framework
    (Technische Universität Dresden, 2024-06-20) Bon, Volodymyr
    The approach of multivariate MOFs was used to fine-tune the mechanical properties of the flexible framework DUT-49. In situ XRD, NMR and physisorption studies showed that the partial incorporation of a more rigid linker into DUT-49 framework enables a stabilization of the metastable open pore phase which led to a twofold amplification of the expelled gas amount upon “Negative Gas Adsorption” transition.

    Data set of the energy demand and associated movement of automated storage and retrieval machines
    (Technische Universität Dresden, 2024-06-24) Siegel, Armin
    The database consists of measurement data from multiple pallet racking storage and retrieval machines (SRMs) and the devices from automatic small parts storage systems (ASPS). The power consumption and the distance traveled by the systems were measured during several measurement operations. There are isolated measurements for the travel and hoist mechanisms of the systems. For power measurement, the Hioki 3193 Power HiTester was used. To capture the distance to the computer, a Dimetix laser distance sensor, model FLS-C 10, was employed. To account for all components and their losses, the power was measured at the aisle connection point. Accordingly, all components of the SRMs, including their losses, were recorded. The measurement setup and detailed methodology are described in the dissertation "Minimierung der Netzanschlussleistung und des Energiebedarfs von Regalbediengerät-Lagersystemen" / "Minimization of grid connection power and energy demand in automated storage and retrieval systems" by Armin Siegel. In addition to the database, which is provided as a compressed SQL file, example queries in Matlab (R2017b) and Python 3 are included.

    Bistable Organic Electrochemical Transistors: Enthalpy vs. Entropy
    (Technische Universität Dresden, 2024-07-03) Bongartz, Lukas
    Organic electrochemical transistors (OECTs) serve as the foundation for a wide range of emerging applications, from bioelectronic implants and smart sensor systems to neuromorphic computing. Their ascent originates from a distinctive switching mechanism based on the coupling of electronic and ionic charge carriers, which gives rise to a multitude of unique characteristics. Notably, various OECT systems have been reported with significant hysteresis in their transfer curve. While being a feature sought after as non-volatile memory in neuromorphic systems, no universal explanation has yet been given for its physical origin, impeding its advanced implementation. Herein, we present a thermodynamic framework that readily elucidates the emergence of bistable OECT operation through the interplay of enthalpy and entropy. We validate our model through three experimental approaches, covering temperature-resolved characterizations, targeted material manipulation, and thermal imaging. In this context, we demonstrate the exceptional scenario where the subthreshold swing deviates from Boltzmann statistics, and we provide an alternate view on existing data in literature, which further supports our model. Finally, we leverage the bistability in form of a single-OECT Schmitt trigger, thus compacting the complexity of a multi-component circuit into a single device. These insights offer a revised understanding of OECT physics and promote their application in non-conventional computing, where symmetry-breaking phenomena are pivotal to unlock novel paradigms.
