KLEVER: An experiment to measure BR($K_L\toπ^0ν\barν$) at the CERN SPS

description: Precise measurements of the branching ratios for the flavor-changing neutral current decays $K\toπν\barν$ can provide unique constraints on CKM unitarity and, potentially, evidence for new physics. It is important to measure both decay modes, $K^+\toπ^+ν\barν$ and $K_L\toπ^0ν\barν$, since different new physics models affect the rates for each channel differently. The NA62 experiment at the CERN SPS will measure the BR for the charged channel to better than 20%. The BR for the neutral channel has never been measured. We are designing the KLEVER experiment to measure BR($K_L\toπ^0ν\barν$) to $\sim$20% using a high-energy neutral beam at the CERN SPS. The boost from the high-energy beam facilitates the rejection of background channels such as $K_L\toπ^0π^0$ by detection of the additional photons in the final state. On the other hand, the layout poses particular challenges for the design of the small-angle vetoes, which must reject photons from $K_L$ decays escaping through the beam exit amid an intense background from soft photons and neutrons in the beam. We present findings from our design studies, with an emphasis on the challenges faced and the potential sensitivity for the measurement of BR($K_L\toπ^0ν\barν$).

description: Recent advances in tuning electronic, magnetic, and topological properties of two-dimensional (2D) magnets have opened a new frontier in the study of quantum physics and promised exciting possibilities for future quantum technologies. In this study, we find that the dual-gate technology can well tune the electronic and topological properties of antiferromagnetic (AFM) even septuple-layer (SL) MnBi$_2$Te$_4$ thin films. Under an out-of-plane electric field that breaks $\mathcal{PT}$ symmetry, the Berry curvature of the thin film could be engineered efficiently, resulting in a huge change of anomalous Hall (AH) signal. Beyond the critical electric field, the double-SL MnBi$_2$Te$_4$ thin film becomes a Chern insulator with a high Chern number of 3. We further demonstrate that such 2D material can be used as an AFM switch via electric-field control of the AH signal. These discoveries inspire the design of low-power memory prototype for future AFM spintronic applications.

description: We have observed coherent time evolution between two quantum states of a superconducting flux qubit comprising three Josephson junctions in a loop. The superposition of the two states carrying opposite macroscopic persistent currents is manipulated by resonant microwave pulses. Readout by means of switching-event measurement with an attached superconducting quantum interference device revealed quantum-state oscillations with high fidelity. Under strong microwave driving it was possible to induce hundreds of coherent oscillations. Pulsed operations on this first sample yielded a relaxation time of 900 nanoseconds and a free-induction dephasing time of 20 nanoseconds. These results are promising for future solid-state quantum computing.

description: We study the steady state fluctuations of an Edwards-Wilkinson type surface with the substrate taken to be a sphere. We show that the height fluctuations on circles at a given latitude has the effective action of a perfect Gaussian $1/f$ noise, just as in the case of fixed radius circles on an infinite planar substrate. The effective surface tension, which is the overall coefficient of the action, does not depend on the latitude angle of the circles.

description: Viral hepatitis is a leading cause of mortality globally, comparable to that of HIV and TB. Most hepatitis deaths are related to liver cirrhosis and hepatocellular carcinoma (HCC) associated with chronic hepatitis B and C infections. To examine the progress towards the elimination goals set in the global health sector strategy for viral hepatitis, we aimed to assess the impact of mortality-indicative morbidity. We retrieved inpatients and day cases hospital discharges data from the Eurostat hospital activities database, and analysed ICD-10 and ICD-9 specific codes related to primary HCC and non-alcohol related cirrhosis registered by European Union/European Economic Area (EU/EEA) countries and United Kingdom (UK) for 2004 to 2015. In 2015, 20 countries (45.7% of total EU/EEA/UK population) reported 13,236 (Range 0–6294) day cases and 36,012 (4–9097) inpatients discharges of HCC. Romania, Croatia, Luxembourg and UK reported increasing day cases discharge rates between 2004 and 2015; while HCC inpatients discharge rates increased overall during this period. There were 13,865 (0–5918) day cases and 56,176 (3–29,118) inpatients discharges reported for cirrhosis across the 20 countries in 2015. Over the 12 years, day cases discharge rates for cirrhosis increased in Romania, Croatia and UK. Though higher than for day cases, cirrhosis inpatients discharge rates remained stable. The hospital burden of HCC and cirrhosis is high, with considerable inpatient load including sustained increasing trends in HCC discharge rates. Further interpretation in light of local health system contexts, and more robust harmonised data are needed to better understand the impact of the viral hepatitis epidemic in the region.

description: Image captioning attempts to generate a sentence composed of several linguistic words, which are used to describe objects, attributes, and interactions in an image, denoted as visual semantic units in this paper. Based on this view, we propose to explicitly model the object interactions in semantics and geometry based on Graph Convolutional Networks (GCNs), and fully exploit the alignment between linguistic words and visual semantic units for image captioning. Particularly, we construct a semantic graph and a geometry graph, where each node corresponds to a visual semantic unit, i.e., an object, an attribute, or a semantic (geometrical) interaction between two objects. Accordingly, the semantic (geometrical) context-aware embeddings for each unit are obtained through the corresponding GCN learning processers. At each time step, a context gated attention module takes as inputs the embeddings of the visual semantic units and hierarchically align the current word with these units by first deciding which type of visual semantic unit (object, attribute, or interaction) the current word is about, and then finding the most correlated visual semantic units under this type. Extensive experiments are conducted on the challenging MS-COCO image captioning dataset, and superior results are reported when comparing to state-of-the-art approaches.

description: A recent publication reports that heavy-ion fusion cross sections at extreme subbarrier energies show a continuous change of their logarithmic slope with decreasing energy, resulting in a much steeper excitation function compared with theoretical predictions. We show that the energy dependence of this slope is partly due to the asymmetric shape of the Coulomb barrier, that is its deviation from a harmonic shape. We also point out that the large low-energy slope is consistent with the surprisingly large surface diffusenesses required to fit recent high-precision fusion data.

description: Aims: Understanding the burden of cancer in Japan is becoming increasingly important to address the socio-economic consequences of the disease. This study broadly examined the cancer burden in terms of: Health-Related Quality of Life (HRQoL), work productivity and activity impairment (WPAI), stress-related comorbidities, and indirect costs in patients diagnosed with (i) any type of cancer, (ii) breast cancer, (iii) colorectal cancer, compared to controls without cancer. Materials and methods: This cross-sectional study used data from the 2017 Japan National Health and Wellness Survey (NHWS). Patient outcomes included self-reported stress-related comorbidities, HRQoL assessed by Short Form 12-item Health Survey and EuroQoL 5-dimension scale (EQ-5D), and work productivity and indirect costs assessed by WPAI questionnaire. Multivariate analysis was performed to compare outcomes across groups. An ad-hoc analysis compared respondents currently and currently not receiving prescription medication (Rx). Results: A total of 1,540 patients with any type of cancer, 254 with breast cancer, 144 with colorectal cancer were included in the analyses and compared to 28,070 controls without cancer. After adjusting for potential confounding effects patients with any type of cancer had significantly lower mental component summary scores (45.70 vs. 46.45, p = .003), physical component summary scores (48.95 vs. 50.02, p vs. 0.79, p vs. 2.68% p Conclusions: Japanese cancer patients experience a significantly decreased HRQoL, increased absenteeism and higher odds ratio for stress-related comorbidities. This has implications for future policy making and Health Technology Assessment in Japan.

description: Aims: The aim of this study was to conduct a cost-effectiveness analysis, as well as a budget impact analysis, on the use of apremilast for the treatment of adult patients with psoriatic arthritis (PsA), within the Italian National Health Service (NHS). Methods: A Markov state transition cohort model, which was adapted to the Italian context, was used to compare the costs of the currently available treatments and of the patients’ quality of life with two alternative treatment sequences, with or without apremilast as pre-biologic therapy. Moreover, a budget impact model was developed based on the population of patients treated for PsA in Italy, who can be eligible for treatment with apremilast. The eligible population was represented by adult patients with PsA who had an inadequate response to or were intolerant to previous disease-modifying antirheumatic drugs (DMARDs), for the approved indication, and for the treatment studied in the economic analytic model. Results: This cost-effectiveness analysis estimated that the strategy of using apremilast before biologic therapy is cost-effective, with an incremental cost-effectiveness ratio of €32,263.00 per QALY gained which is slightly over the normal threshold found in other Italian economic studies, which usually considers a 40-year-period. Conversely, the budget impact analysis was conducted over 3 years, and it led to an estimated annual saving of €1.6 million, €4.6 million and €5.5 million in the first, second and third year of apremilast commercialization, respectively, for a total saving of €11.75 million in 3 years. Limitations: Limitations of this analysis include the absence of head-to-head trials comparing therapies included in the economic model, the lack of comparative long-term data on treatment efficacy, and the assumption of complete independence between the considered response rates to therapy. Conclusion: The use of apremilast as a first option before the use of biologic agents may represent a cost-effective treatment strategy for patients with PsA who fail to respond to, or are intolerant to, previous DMARD therapy. In addition, based on a budget impact perspective, the use of apremilast may lead to cost savings to the Italian healthcare system.
High-p_T Charged Hadron Suppression in Au+Au Collisions at sqrt(s_NN) = 200 GeV

description: The PHENIX experiment at RHIC has measured charged hadron yields at mid-rapidity over a wide range of transverse momentum (0.5 < p_T < 10 GeV/c) in Au+Au collisions at sqrt(s_NN)=200 GeV. The data are compared to pi^zero measurements from the same experiment. For both charged hadrons and neutral pions, the yields per nucleon-nucleon collision are significantly suppressed in central compared to peripheral and nucleon-nucleon collisions. The suppression sets in gradually and increases with increasing centrality of the collisions. Above 4-5 GeV/c in p_T, a constant and almost identical suppression of charged hadrons and pi^zeroes is observed. The p_T spectra are compared to published spectra from Au+Au at sqrt(s_NN)=130 in terms of x_t scaling. Central and peripheral pi^zero as well as peripheral charged spectra exhibit the same x_t scaling as observed in p+p data.

description: Energetic neutral atoms (ENA) are an important tool for investigating the structure of the heliosphere. Recently, it was observed that fluxes of ENAs (with energy $\le$ 55 keV) coming from the upwind and downwind regions of the heliosphere are similar in strength. This led the authors of these observations to hypothesize that the heliosphere is bubble-like rather than comet-like, meaning that it has no extended tail. We investigate the directional distribution of the ENA flux for a wide energy range (3--88 keV) including the observations from IBEX (Interstellar Boundary Explorer), INCA (Ion and Neutral Camera, on board Cassini), and HSTOF (High energy Suprathermal Time Of Flight sensor, on board SOHO, Solar and Heliospheric Observatory). An essential element is the model of pickup ion acceleration at the termination shock (TS) proposed by Zank. We use state of the art models of the global heliosphere, interstellar neutral gas density, and pickup ion distributions. The results, based on the "comet-like" model of the heliosphere, are close in flux magnitude to ENA observations by IBEX, HSTOF and partly by INCA (except for the 5.2-13.5 keV energy channel). We find that the ENA flux from the tail dominates at high energy (in agreement with HSTOF, but not INCA). At low energy, our comet-like model produces the similar strengths of the ENA fluxes from the upwind and downwind directions, which, therefore, removes this as a compelling argument for a bubble-like heliosphere.

description: Uncomplicated urinary tract infection (UTI) causes bothersome symptoms among women and is a leading cause for antibiotic prescribing in primary healthcare (PHC). A prospective observational study in eight different PHC centres in Sweden including 192 women with symptoms of uncomplicated UTI. Questionnaires and symptom diaries were used to retrieve patient data. All urine samples were analysed with urine culture and susceptibility testing. The aim was to describe the clinical presentation of symptoms in uncomplicated UTI in relation to bacterial findings in urine and to describe the course and duration of symptoms in relation to anamnestic factors, bacterial findings and antibiotic treatment. Median symptom duration before seeking care was four days (IQR 1–7). Restrictions in daily life related to symptoms of uncomplicated UTI were reported by the majority (74%) of respondents. The median number of days concerning any symptom after consultation was 4.0 days (IQR 2.0–5.0) for patients treated with antibiotics, and 6.5 days (IQR 3.0–10.0) for patients not treated with antibiotics. There was an association between longer symptom duration after consultation and age over 50 years, relative risk (RR) 1.76 (95% CI 1.25–2.49). Antibiotic treatment RR 0.47 (95% CI 0.27–0.81) was associated with reported shorter duration of symptoms. Women visiting primary health care with symptoms indicating uncomplicated UTI have symptoms for several days before seeking care and after consulting. A majority of patients feel restricted in their daily activities due to uncomplicated UTI. Older women and women not treated with antibiotics have the longest symptom duration after consultation.

Rigorous Analysis of Singularities and Absence of Analytic Continuation at First Order Phase Transition Points in Lattice Spin Models

description: We report about two new rigorous results on the non-analytic properties of thermodynamic potentials at first order phase transition. The first one is valid for lattice models ($d\geq 2$) with arbitrary finite state space, and finite-range interactions which have two ground states. Under the only assumption that the Peierls Condition is satisfied for the ground states and that the temperature is sufficiently low, we prove that the pressure has no analytic continuation at the first order phase transition point. The second result concerns Ising spins with Kac potentials $J_γ(x)=γ^dϕ(γx)$, where $00$) and analyticity in the mean field limit ($γ\searrow 0$). In general, the basic mechanism responsible for the appearance of a singularity blocking the analytic continuation is that arbitrarily large droplets of the other phase become stable at the transition point.

By studying the quantitative change trends and spatial differences of the utilization benefit of cultivated land resources in Guangxi, it came up with recommendations for optimizing the allocation of cultivated land from the quantity and quality of cultivated land. It is intended to provide a scientific and theoretical reference for improving the use efficiency of cultivated land in Guangxi.

description: Entrainment by a pacemaker, representing an element with a higher frequency, is numerically investigated for several classes of random networks which consist of identical phase oscillators. We find that the entrainment frequency window of a network decreases exponentially with its depth, defined as the mean forward distance of the elements from the pacemaker. Effectively, only shallow networks can thus exhibit frequency-locking to the pacemaker. The exponential dependence is also derived analytically as an approximation for large random asymmetric networks.

The maximal possibility 23 can only occur in the smooth case. In addition to the known smooth examples with second Betti numbers 7 and 23, we provide examples of such orbifolds with second Betti numbers 3, 5, 6, 8, 9, 10, 11, 14 and 16. In an appendix, we extend Salamon's relation among Betti/Hodge numbers of symplectic manifolds to symplectic orbifolds.

description: We theoretically expanded the capabilities of optical sensing based on surface plasmon resonance in a prism-coupled configuration by incorporating artificial neural networks (ANNs). We used calculations modeling the situation in which an index-matched substrate with a metal thin film and a porous chiral sculptured thin film (CSTF) deposited successively on it is affixed to the base of a triangular prism. When a fluid is brought in contact with the exposed face of the CSTF, the latter is infiltrated. As a result of infiltration, the traversal of light entering one slanted face of the prism and exiting the other slanted face of the prism is affected. We trained two ANNs with differing structures using reflectance data generated from simulations to predict the refractive index of the infiltrant fluid. The best predictions were a result of training the ANN with simpler structure. With realistic simulated-noise, the performance of this ANN is robust.

The development of modern agriculture requires widening the scope of insurance coverage. Therefore, the paper analyzes the possibility of adjusting insurance offers to the specific needs in agriculture sector with the aim of increasing the number of insured business entities. First, it is necessary to properly define the marketing mix in agricultural insurance. Second, it is equally important to permanently measure effectiveness and legitimacy of its application. Importance of the most commonly used indicator - the Return on Marketing Investment Coefficient (ROMI), is underlined.

description: We study a simplest viable dark matter model with a real singlet scalar, vector-like singlet and a doublet lepton. We find a considerable enhancement in the allowed region of the scalar dark matter parameter spaces under the influence of the new Yukawa coupling. The Yukawa coupling associate with the fermion sector heavily dominant the dark matter parameter spaces satisfying the current relic density of the Universe. Dilepton$+\slashed{E}_T$ signature arising from the new fermionic sector can observe at Large Hadron Collider (LHC). We perform such analysis in the context of 14 TeV LHC experiments with a future integrated luminosity of 3000 ${\rm fb^{-1}}$. We found that a large region of the parameter spaces can be probed by the LHC experiments. The projected exclusion/discovery reach of direct heavy charged fermion searches in this channels is analyzed by performing a detailed cut based collider analysis. The projected exclusion contour reaches up to $1050-1380~{\rm GeV}$ for 3000 ${\rm fb^{-1}}$ for a light dark matter $\mathcal{O}(10)$ GeV from searches in the $ pp \rightarrow E_1^\pm E_1^\mp, E_1^\pm\rightarrow l^\pm S \rightarrow ll + \slashed{E}_T$ channel.

description: There is a continuous rise in the rate of medicine consumption because of the development of drug resistance by microbial pathogens. In the last one decade, silver nanoparticles (AgNPs) have become a remarkable choice for the development of new drugs due to their excellent broad-spectrum antimicrobial activity. In the current pieceof work, we have synthesized AgNPs from the root extract of Phoenix dactylifera to test their antimicrobial andanti-cancer potential. UV–visible spectra showed the surface plasmon resonance peak at 420 nm λmax correspondingto the formation of silver nanoparticles, FTIR spectra further confirmed the involvement of biologicalmoieties in AgNPs synthesis. Moreover, XRD analysis showed the crystalline nature of AgNPs and predicted thecrystallite size of 15 to 40 nm. Electron microscopy analyses confirmed their spherical shape. In addition, synthesizedAgNPs was also found to control the growth of C. albicans and E. coli on solid nutrient medium with 20and 22mm zone of inhibition, respectively. The 100% potency at 40 μg/ml AgNPs concentration was observedagainst E. coli and C. albicans after 4 h and 48 h incubation respectively. Importantly, AgNPs were also found todecrease the cell viability of MCF7 cell lines in vitro with IC50 values of 29.6 μg/ml and could act as a controllingagent of human breast cancer. Based on our results, we conclude that biologically synthesized AgNPs exhibited multifunctional properties and could be used against human cancer and other infectious diseases.

description: Genus Naquetia Jousseaume, 1880
 TYPE SPECIES. — Murex triqueter Born, 1778, Indo-West Pacific (by original designation).
REMARKS
 Naquetia and Chicomurex Arakawa, 1964 are two muricine genera with closely similar shell morphology, with an average height of 40-120 mm in Naquetia and 30-85 mm in Chicomurex. The protoconch is paucispiral, consisting of 1.5- 2 whorls, or conical of sinusigera type, with 3-3.5 glossy whorls, usually with a narrow keel abapically. Each teleoconch whorl bears three rounded, squamous varices from the second or third whorl, with short, broadly open spines connected by squamous webbing. The radula is similar in the two genera, consisting of crowded rows of teeth with a rachidian bearing a large, broad, triangular central cusp (Houart 1992: figs 116-128) and Figure 8A, B.
 The type species of Chicomurex, C. laciniatus (Sowerby, 1841) differs from the type species of Naquetia in having a broader and more globose shell, a comparatively lower spire and a proportionally larger and broader aperture. Within these two genera, all species consistently exhibit this distinction. The two genera are also distinct in a molecular phylogenetic analysis (Barco et al. 2010).
 The new species described here is included in Naquetia in spite of the slightly broader shell relative to its length compared to other Naquetia species and the relatively low spire. However, it differs from Chicomurex in having a short, broad, squamous siphonal canal, relatively shorter variceal spines and a more strongly triangular outline, which are typical characters of Naquetia.

description: We explain quantitatively, within the Gutzwiller-Resonating Valence Bond theory, the puzzling observation of tunneling conductivity between a metallic point and a cuprate high-$T_c$ superconductor which is markedly asymmetric between positive and negative voltage biases. The asymmetric part does not have a "coherence peak" but does show structure due to the gap. The fit to data is satisfactory within the over-simplifications of the theory; in particular, it explains the marked "peak-dip-hump" structure observed on the hole side and a number of other qualitative observations. This asymmetry is strong evidence for the projective nature of the ground state and hence for "t-J" physics.

description: We analyse the flat space limit of 3-point correlators in momentum space for general conformal field theories in even spacetime dimensions, and show they exhibit a double copy structure similar to that found in odd dimensions. In even dimensions, the situation is more complicated because correlators contain branch cuts and divergences which need to be renormalised. We describe the analytic continuation of momenta required to extract the flat space limit, and show that the flat space limit is encoded in the leading singularity of a 1-loop triangle integral which serves as a master integral for 3-point correlators in even dimensions. We then give a detailed analysis of the renormalised correlators in four dimensions where the flat space limit of stress tensor correlators are controlled by the coefficients in the trace anomaly.

description: Knowledge on bacterial co-infections in COVID-19 is crucial to use antibiotics appropriately. Therefore, we aimed to determine the incidence of bacterial co-infections, antibiotic use and application of antimicrobial stewardship principles in hospitalized patients with COVID-19. We performed a retrospective observational study in four hospitals (1 university, 2 non-university teaching, 1 non-teaching hospital) in the Netherlands from March to May 2020 including consecutive patients with PCR-confirmed COVID-19. Data on first microbiological investigations obtained at the discretion of the physician and antibiotic use in the first week of hospital admission were collected. Twelve (1.2%) of the 925 patients included had a documented bacterial co-infection (75.0% pneumonia) within the first week. Microbiological testing was performed in 749 (81%) patients: sputum cultures in 105 (11.4%), blood cultures in 711 (76.9%), pneumococcal urinary antigen testing in 202 (21.8%), and Legionella urinary antigen testing in 199 (21.5%) patients, with clear variation between hospitals. On presentation 556 (60.1%; range 33.3–73.4%) patients received antibiotics for a median duration of 2 days (IQR 1–4). Intravenous to oral switch was performed in 41 of 413 (9.9%) patients who received intravenous treatment >48 h. Mean adherence to the local guideline on empiric antibiotic therapy on day 1 was on average 60.3% (range 45.3%–74.7%). On presentation to the hospital bacterial co-infections are rare, while empiric antibiotic use is abundant. This implies that in patients with COVID-19 empiric antibiotic should be withheld. This has the potential to dramatically reduce the current overuse of antibiotics in the COVID-19 pandemic.

description: The importance of crucial nutrient factors like Phosphate (P) and their limited availability leads to variable fluctuations in fatty acid and phospholipid synthesis in the green alga. These fatty acids and phospholipids are an imperative byproduct of alga which used in biofuel production. The production of phospholipids in alga might be naturally enhanced by the optimized supplied by specific essential nutrient like Phosphate. In this study, green alga Chlamydomonas reinhardtii was cultivated in phosphate stress condition to obtain maximum phospholipids. In the stress condition, the organism exhibited variable changes in chlorophyll, fatty acid, and phospholipid compositions. These parameters analyzed by biomass, X-ray, GC, and TLC. Remarkably, saturated fatty acids, monounsaturated, and di-unsaturated fatty acids amounts, increases, while polyunsaturated fatty acids to decrease markedly. The maximum fatty acid content observed at 0.4 mgl−1 P content in growing media. A broad peak area of 56% of hexadecanoic acid (C 16:0) and followed by 28.8% linolenic (C18:3) was observed in GC analysis. These results indicate the essential fatty acid accumulation maximized at particular phosphate concentration in growing media. This necessary and essential fatty acid production from green algae in a sustainable manner is an inexpensive and excellent way for commercialization and biofuel production.

description: Spins in gate-defined silicon quantum dots are promising candidates for implementing large-scale quantum computing. To read the spin state of these qubits, the mechanism that has provided the highest fidelity is spin-to-charge conversion via singlet-triplet spin blockade, which can be detected in-situ using gate-based dispersive sensing. In systems with a complex energy spectrum, like silicon quantum dots, accurately identifying when singlet-triplet blockade occurs is hence of major importance for scalable qubit readout. In this work, we present a description of spin blockade physics in a tunnel-coupled silicon double quantum dot defined in the corners of a split-gate transistor. Using gate-based magnetospectroscopy, we report successive steps of spin blockade and spin blockade lifting involving spin states with total spin angular momentum up to $S=3$. More particularly, we report the formation of a hybridized spin quintet state and show triplet-quintet and quintet-septet spin blockade. This enables studies of the quintet relaxation dynamics from which we find $T_1 \sim 4 ~μs$. Finally, we develop a quantum capacitance model that can be applied generally to reconstruct the energy spectrum of a double quantum dot including the spin-dependent tunnel couplings and the energy splitting between different spin manifolds. Our results open for the possibility of using Si CMOS quantum dots as a tuneable platform for studying high-spin systems.

description: Die wissenschaftliche Master Thesis befasst sich mit psychosozialen Verarbeitungsformen von kriegsbedingten Erfahrungen und Fluchterfahrungen sowie mit Veränderungsprozessen traumatisierter Flüchtlinge in einer dolmetschunterstützten Gruppe. Sie untersucht, welche Rolle die Psychodramatische Lebenslinien-Arbeit (PDLLA) und Gruppenpsychotherapie dabei spielen kann. Das Design der Untersuchung ist qualitativ-empirisch ausgerichtet. Die Ergebnisse der Feldforschung wurden mit einer (aktiven) Teilnehmenden Beobachtung erhoben, in Protokollen dokumentiert und anschließend mit Hilfe Psychodramatischen Szenischen Verstehens ausgewertet. Die Grundgesamtheit setzt sich aus fünf arabisch- sprachigen Männern zusammen. Anhand von Beispielen konnte gezeigt werden, dass eine wohldosierte Traumaexposition mit Hilfe der Distanzierungstechnik Psychodramatische Lebenslinien-Arbeit in der Gruppe gelingen kann. This academic master thesis aims at researching psycho-social forms of processing both war- and migration-related experiences, as well as change processes of traumatised refugees within a group supported by an interpreter. It examines the possible role of psycho-dramatic group psychotherapy and psycho-dramatic lifeline work in this area. The research is designed qualitatively and empirically. The field study was conducted as an (active) participatory observation and was then documented in protocols before being evaluated by means of psycho-dramatic scenic understanding. The basic population was made up of five Arabic-speaking men. Using examples, it becomes apparent that a balanced exposure to the trauma aided by the dissociation technique of psycho-dramatic lifeline work within a group can be successful.
