title: Designing Awareness Tools for Psychological Well-Being in Collaborative Work Environments
Creators: name: Lushnikova, Alina
Publisher: name: European Society for Socially Embedded Technologies (EUSSET)
Year: 2023

description: The work practices and tools supporting them are rapidly shifting to hybrid, making computer-supported collaboration more and more salient. Because of the novelty of this modality and imposed pressure to perform, employee well-being is at risk. Awareness support can be an empowering solution when designed in line with human-centered values and well-being as an objective. This thesis investigates how awareness tools can support the psychological well-being of people working together by enabling self-reflection and self-regulation. First, it aims at consolidating knowledge about the roles of awareness support in hybrid contexts. Second, based on empirical research, the thesis strives to derive the design guidelines of awareness support tools that improve the well-being of the employee collaborators. Third, it explores the opportunities to bridge the experience-centeredness of UX and orientation on social practices of CSCW.
Eikonal instability of Gauss-Bonnet-(anti-)de Sitter black holes

description: Here we have shown that asymptotically anti-de Sitter (AdS) black holes in the Einstein-Gauss-Bonnet (GB) theory are unstable under linear perturbations of spacetime in some region of parameters. This (eikonal) instability develops at high multipole numbers. We found the exact parametric regions of the eikonal instability and extended this consideration to asymptotically flat and de Sitter cases. The approach to the threshold of instability is driven by purely imaginary quasinormal modes, which are similar to those found recently in [5] for the higher curvature corrected black hole with the planar horizon. The found instability may indicate limits of holographic applicability of the GB-AdS backgrounds. Recently, through the analysis of critical behavior in AdS space-time in the presence of Gauss-Bonnet term, it was shown [19] that that, if the total energy content of the AdS space-time is small, then no black holes can be formed with mass less than some critical value. A similar mass gap was also found when considering collapse of mass shells in asymptotically flat Gauss-Bonnet theories [20]. The found instability of all sufficiently small Einstein-Gauss-Bonnet-AdS, -dS and asymptotically flat black holes may explain the existing mass gaps in their formation.

survey

description: A survey issued to hospital (diabetes service) staff before participating in a tailoring process to develop strategies to enhance the implementation of a structured diabetes education programme for people with type 1 diabetes, called DAFNE (Dose Adjustment for Normal Eating). Participants are asked to complete this survey to describe the characteristics of their DAFNE site. The survey (version 1) includes items to assess inner setting measures as per the Consolidated Framework for Implementation Research (CFIR) (culture, learning climate, implementation climate, leadership, available resources). For sites which are new to implementing DAFNE, the survey (version 2) also includes questions about their readiness for implementation. As part of this survey, staff are asked to consider a list of determinants, indicate whether each determinant is a barrier or enabler at their site, and to supplement or remove determinants from this list as they relate to their experience of implementation. This list is based on rapid evidence review of the existing literature on the implementation of structured diabetes education programmes.

description: The archaeological research project done in Are’are since 2011 has been the first to be done in the area. The project is made through the cooperation between the Ministry of Culture and Tourism and the German Archaeological Institute, Commission for Archaeology of Non-European Cultures through Johannes Moser. Mr. John Tahinao the Director for Culture then is very instrumental in supporting the project and he was the person who suggested that the project must be done in his area. There is no doubt that being a trained Archaeologist at the University of Papua New Guinea he already knew that there is a potential of lithic site in his area. Mr. Tahinao has continuously appreciated every single progress of the project and in one of his respond he said the following words ‘The project is now gaining momentum’. The statement shows that the project has been successfully appreciated by the people, whom the project has been done, and the Ministry of Culture and Tourism in Honiara.

description: High-dimensional quantum key distribution (QKD) offers secure communication, with secure key rates that surpass those achievable by QKD protocols utilizing two-dimensional encoding. However, existing high-dimensional QKD protocols require additional experimental resources, such as multiport interferometers and multiple detectors, thus raising the cost of practical high-dimensional systems and limiting their use. Here, we present and analyze a novel protocol for arbitrary-dimensional QKD, that requires only the hardware of a standard two-dimensional system. We provide security proofs against individual attacks and coherent attacks, setting an upper and lower bound on the secure key rates. Then, we test the new high-dimensional protocol in a standard two-dimensional QKD system over a 40 km fiber link. The new protocol yields a two-fold enhancement of the secure key rate compared to the standard two-dimensional coherent one-way protocol, without introducing any hardware modifications to the system. This work, therefore, holds great potential to enhance the performance of already deployed time-bin QKD systems through a software update alone. Furthermore, its applications extend across different encoding schemes of QKD qudits.

description: This paper deals with the following question: which manifolds can be realized as leaves of codimension-1 symplectic foliations on closed manifolds? We first observe that leaves of symplectic foliations are necessarily strongly geometrically bounded. We show that a symplectic structure which admits an exhaustion by compacts with (convex) contact boundary can be deformed to a strongly geometrically bounded one. We then give examples of smooth manifolds which admit a strongly geometrically bounded symplectic form and can be realized as a smooth leaf, but not as a symplectic leaf for any choice of symplectic form on them. Lastly, we show that the (complex) blowup of 2n-dimensional Euclidean space at infinitely many points, both admits strongly geometrically bounded symplectic forms for which it can and cannot be realized as a symplectic leaf.

description: The thermal alteration associated with human remains in prehispanic contexts of South America is not uncommon. In relation to this type of burial custom many interpretations have been given, ranging from the preservation of the body in order to perform double funerals, to the ingestion of human remains in contexts of anthropophagic practices. This paper presents new data related to the mortuary diversity in populations of San Francisco tradition of the Yungas or mountain rainforest of Jujuy, Argentina (800 B. C.–500 A. D.), especially those involving heat treatment of bone remainders. Contextual associations of the fi ndings are discussed by comparing them with other registered at different sites in the region in more than one century of discontinuous research. The information comes especially from exhumation contexts at the site Pozo de la Chola.

description: Introduction Cervical artificial insemination (AI) with frozen-thawed semen in sheep has yielded unacceptably low pregnancy rates. The exception is in Norway where vaginal AI yields non-return rates in excess of 60%, which has been attributed to the ewe breed used. Objectives and methods This study aimed to characterise, for the first time, the ovine follicular phase cervical mucus metabolome, with a focus on the amino acid profile. Cervical mucus was collected from four European ewe breeds with known differences in pregnancy rates following cervical AI with frozen-thawed semen. These were Suffolk (low fertility), Belclare (medium fertility), Norwegian White Sheep (NWS) and Fur (both high fertility). Results A total of 689 metabolites were identified in the cervical mucus of all the four ewe breeds. Of these, 458 metabolites were altered by ewe breed, which had the greatest effect in the dataset (P<0.05). We detected 194 metabolites involved in the amino acid pathway, of which 133, 56 and 63 were affected by ewe breed, type of cycle and their interaction, respectively (P<0.05). N-methylhydantoin and N-carbamoylsarcosine (degradation products of creatinine pathway) exhibited the greatest fold change decrease in the Suffolk breed compared to Fur and NWS (P<0.001). Oxidized metabolites were also decreased in Suffolk compared to high fertility breeds (P<0.05). In contrast, other metabolites such as 3-indoxyl-sulfate, putrescine, cadaverine were significantly increased in Suffolk at the synchronised cycle. Conclusion The suboptimal amino acid profile in the cervical mucus of the low fertility Suffolk breed may have negative consequences for sperm transport.

description: Blood oxygen saturation (SpO$_2$) is an essential indicator of respiratory functionality and is receiving increasing attention during the COVID-19 pandemic. Clinical findings show that it is possible for COVID-19 patients to have significantly low SpO$_2$ before any obvious symptoms. The prevalence of cameras has motivated researchers to investigate methods for monitoring SpO$_2$ using videos. Most prior schemes involving smartphones are contact-based: They require a fingertip to cover the phone's camera and the nearby light source to capture re-emitted light from the illuminated tissue. In this paper, we propose the first convolutional neural network based noncontact SpO$_2$ estimation scheme using smartphone cameras. The scheme analyzes the videos of a participant's hand for physiological sensing, which is convenient and comfortable, and can protect their privacy and allow for keeping face masks on. We design our neural network architectures inspired by the optophysiological models for SpO$_2$ measurement and demonstrate the explainability by visualizing the weights for channel combination. Our proposed models outperform the state-of-the-art model that is designed for contact-based SpO$_2$ measurement, showing the potential of our proposed method to contribute to public health. We also analyze the impact of skin type and the side of a hand on SpO$_2$ estimation performance.

Tissamaharama Pottery sequence and the Early Historic maritime Silk Route across the Indian Ocean
Creators: name: Schenk, Heidrun

Year: 2023

description: Tissamaharama pottery sequence represents the regional development of pottery manufactured from 5th century B. C. E. to 12th / 13th century C. E. in Sri Lanka. The results reach beyond the island and include new perspectives on pottery that came from the Roman Empire, Mesopotamia, Northern India, Southeast Asia and China and distinctly illustrates cross-continental relations in the Indian Ocean region of Early Historic Period. A short overview is given here, but main focus is the Pre-Periplus maritime connection based on the evaluation of “Fine Grey Pottery from Northern India” at Tissamaharama. Their find spots trace Indian Ocean maritime routes as physical evidence in Pre-Roman times, which cover Southeast Asia differently to the picture drawn by the later Periplus. Earliest fi nds of this pottery group confi rm connections along the East Coast of India already in the 5th / 4th century B. C. Trans-continental routing across the Indian Ocean is then evidenced by finds like the well-known “Rouletted Ware” in the 2nd century B. C. It is suggested that they were transported from ports in the South of the Subcontinent. There, an emporium had formed in the course of time because favourable sailing conditions allow direct contacts of Western and Eastern Indian Ocean. The finds of “Fine Grey Pottery” in Southeast Asia evidence an earlier formation of the Eastern maritime network. To facilitate further research and to prevent the further use of misleading denominations, a draft of chronology and a new typology of “Fine Grey Pottery from Northern India” are proposed here. The southern made “imitation” of the dish with beaked rim (often mistaken for true “Rouletted Ware”) will be once more described and proposed as an important key type to prove the actual ports of embarkation.

description: This PhD project aims to explore how economic value is generated by data in data-driven technologies and the role of contextual and informal social relations in these valuation processes. Conducting ethnography in existing socio-technical networks ‘in the wild’, this PhD situates its focus on the healthcare sector. This project aims is to explore how the existing data practices, from the micro level of the data- practitioners to the mezzo level of the data stewards, construct value propositions for the ways data value is traded and regulated by the policymakers. Ethnographic fieldwork for this PhD research has already been conducted in two northern European companies in the Health Tech Industry. Further research is planned to be conducted in the public and private healthcare sectors in UK, Denmark and Greece.

description: Almost twenty years of excavation at Tissamaharama, southern Sri Lanka, have produced an immense number of pottery sherds. More than one hundred carry comprehensible legends in Brāhmī letters, dating back to centuries before and after Christ. They allow for the fi rst time to accompany the Buddhist monks and nuns in their numerical development over centuries and their interaction with sponsors and supporters. Nunneries are otherwise almost untraceable, while here we have a domination of nuns and laywomen over their male counterparts. Tamil speaking components of society are few but perceptible, particularly during the foundation phase.

description: Purpose: To develop a rapid imaging framework for balanced steady-state free precession (bSSFP) that jointly reconstructs undersampled data (by a factor of R) across multiple coils (D) and multiple acquisitions (N). To devise a multi-acquisition coil compression technique for improved computational efficiency. Methods: The bSSFP image for a given coil and acquisition is modeled to be modulated by a coil sensitivity and a bSSFP profile. The proposed reconstruction by calibration over tensors (ReCat) recovers missing data by tensor interpolation over the coil and acquisition dimensions. Coil compression is achieved using a new method based on multilinear singular value decomposition (MLCC). ReCat is compared with iterative self-consistent parallel imaging (SPIRiT) and profile encoding (PE-SSFP) reconstructions. Results: Compared to parallel imaging or profile-encoding methods, ReCat attains sensitive depiction of high-spatial-frequency information even at higher R. In the brain, ReCat improves peak SNR (PSNR) by 1.1$\pm$1.0 dB over SPIRiT and by 0.9$\pm$0.3 dB over PE-SSFP (mean$\pm$std across subjects; average for N=2-8, R=8-16). Furthermore, reconstructions based on MLCC achieve 0.8$\pm$0.6 dB higher PSNR compared to those based on geometric coil compression (GCC) (average for N=2-8, R=4-16). Conclusion: ReCat is a promising acceleration framework for banding-artifact-free bSSFP imaging with high image quality; and MLCC offers improved computational efficiency for tensor-based reconstructions.

The Power of Images – Coin Portraits of Roman Emperors on Jewellery Pendants in Early Southeast Asia
Creators: name: Borell, Brigitte
Publisher: name: Zeitschrift für Archäologie Außereuropäischer Kulturen
Year: 2023

description: This contribution presents fi nds of jewellery pendants with imitations of Roman coins from Southeast Asia. The examples from Óc Eo in southern Vietnam have been known already since the 1940s. The state of our knowledge has now been broadened by the fi nds from U Thong and Khlong Thom in Thailand. In some cases, the great faithfulness of the imitations permits an exact identification of the original prototype. The fi nd of a mould leads to the conclusion of local production. The custom of wearing Roman coins or their imitations as pendants is documented by numerous finds from southern India. The equivalent phenomenon in Southeast Asia is to be seen in the context of the network of maritime routes. In the early centuries after the turn of the era, their connections extended from the South China Sea to the Mediterranean. Questions arise regarding the reception and meaning of the depictions on these jewellery pendants in their respective Eastern environment.

Year: 2023

description: With aging societies and care crises on the one hand and new robotic technology and artificial intelligence on the other, there are certain hopes that the technology of the future can provide solutions to social problems. My dissertation aims to paint a realistic picture of the situation and to point out not only potential but desirable developments. My focus is on care for people of older age, and I am particularly interested in the entanglement of work, organization, and technology following a sociomaterial approach. Specifically, I want to explore how and under what conditions new (robotic) technology can be aligned with the values and professional identities of those working in care. Furthermore, I would like to investigate these aspects on the level of processes and structures of the organization. Methodologically, I am following a qualitative social research approach, with data being collected in the context of the project ‘Caring Robots // Robotic Care’. Finally, with my dissertation, I aim at contributing to the knowledge of how technology development in the field of care can take into account ethical aspects and the interests of the various affected groups.

description: Einleitend stellt die Autorin die soziopolitische Rolle des Sports dar. Ausgehend von dieser besonderen Rolle des Sports, aber auch des (Sport)Films, lautet das Ziel: "Mittels einer interdisziplinären Analyse sollen deshalb […] die gesellschaftlichen Phänomene Sport, Rassismus und Diskriminierung miteinander verknüpft und deren Wechselwirkung in ihrer Gesamtheit betrachtet werden." In Theorieteil werden die zentralen Begriffe Rassismus und Diskriminierung im Sport eingeführt und ein Überblick über das System der Apartheid in Südafrika gegeben. Auch wird die Politik Mandelas im Kontext der Rugby-WM 1995 skizziert. Es folgt eine Analyse der Beziehung von Sport und Medien, des Sportfilms und des sportsoziologischen Erkenntnisinteresses desselben. Die Analyse des Films folgt dem Dreischritt "Entstehung -Inhalt - Analyse der ausgewählten Sequenzen". Hervorzuheben ist hierbei, dass der Autorin die Verknüpfung der filmischen, soziologischen und sportlichen Aspekte hervorragend gelingt.

description: The Kepler light curve of DF Cyg is unparalleled in precision and cadence for any RV Tau star to date spanning a baseline of $\sim$4 years and clearly displaying the signature pulsating behavior of alternating deep and shallow minima as well as the long-term trend indicative of an RVb-type variable. We measured DF Cyg's formal period (the time interval between two successive deep minima) to be $~49.84 \pm 0.02~$days. The trend in the arrival times emulates that of the long-term period. There appears to be precisely 16 deep+shallow minima cycles in one long-term cycle, suggesting a long-term cycle period of $\approx$ $795 \pm 5~$days. We argue that binarity may naturally explain the long-term periodicity in DF Cyg. The spectral energy distribution of DF Cyg features an infrared excess indicative of a disk possibly linked to a binary companion. From a recent Gaia parallax measurement for DF Cyg, we calculated that it has a distance of $990 \pm 372$pc and a physical radius of $R_\star = 10.3 \pm 3.8$ R$_\odot$. From kinematics and geometric arguments, we argue that the most likely interpretation for the decrease in flux from the long-period maximum to the long-period minimum, as well as the reduction of short-term pulsation amplitude, is caused by an occulting body such as a disk surrounding DF Cyg and its binary companion.

The decay of the transmission is typically probed at a given energy or frequency. Here we show that this decay affects the dynamics of a qubit coupled to the disordered system and we express the relaxation rate of the qubit in terms of the localization properties. Conversely, adding static disorder to a channel coupled to a qubit will reduce the decoherence rate of the qubit. Hence, when designing electrodes that couple to qubits it is possible to improve their performance by adding impurities to the channel.

description: Das Ziel der Arbeit war es, den aktuellen Forschungsstand der Verletzungsprävention in der Sportart Volleyball aufzubereiten, um anschließend Empfehlungen aussprechen zu können. Somit wurden im Ergebnis, durch die Methode der systematischen Literaturrecherche, die aktuellen (möglichen) Präventionsmaßnahmen für die im Volleyball am häufigsten betroffenen Körperregionen Knie, Knöchel und Schulter zusammengestellt. Nach Betrachtung der Risikofaktoren für die volleyballspezifischen Verletzungen und bisherigen Maßnahmen der Stiftung, konnten schließlich Defizite identifiziert werden. Ergebnisbasierend wurde eine mögliche Änderung der vier Handlungsfelder der Unfallprävention im Volleyball vorgeschlagen, in der die Prävention nach den drei am häufigsten betroffenen Körperregionen ausgerichtet ist. Letztendlich sollen die Handlungsfelder zukünftig spezifischer werden, um Verletzungen und Unfälle zielgerichtet zu reduzieren.
description: The aim of this thesis was to present the current state of research on injury prevention in the sport of volleyball to be able to make recommendations for the four fields of action for accident prevention. These recommendations should be implemented in the project "Vereinssport in der Kommune – Mit Sicherheit verletzungsfrei of the Stiftung Sicherheit im Sport", in order to achieve a more effective reduction of injuries and accidents in the future. As a result, the current (possible) preventive measures for the body regions most frequently affected in volleyball - knee, ankle and shoulder - were compiled using the method of systematic literature research. After considering the risk factors for volley-ball-specific injuries and previous measures of the foundation, deficits could be iden-tified. Finally, a possible change of the fields of action was suggested, in which the prevention is aligned according to the three body regions. Thus, the fields of action should become more specific in the future to reduce injuries and accidents in a tar-geted manner.

description: Metal hydrides have been studied for use in energy storage, hydrogen storage, and air-conditioning (A/C) systems. A common architecture for A/C and energy storage systems is two metal hydride reactors connected to each other so that hydrogen can flow between them, allowing for cyclic use of the hydrogen. This paper presents a nonlinear dynamic model and multivariate control strategy of such a system. Each reactor is modelled as a shell-and-tube heat exchanger connected to a circulating fluid, and a compressor drives hydrogen flow between the reactors. We further develop a linear state-space version of this model integrated with a model predictive controller to determine the fluid mass flow rates and compressor pressure difference required to achieve desired heat transfer rates between the metal hydride and the fluid. A series of case studies demonstrates that this controller can track desired heat transfer rates in each reactor, even in the presence of time-varying circulating fluid inlet temperatures, thereby enabling the use of a two-reactor system for energy storage or integration with a heat pump.

description: Blood oxygen saturation (SpO$_2$) is an important indicator for pulmonary and respiratory functionalities. Clinical findings on COVID-19 show that many patients had dangerously low blood oxygen levels not long before conditions worsened. It is therefore recommended, especially for the vulnerable population, to regularly monitor the blood oxygen level for precaution. Recent works have investigated how ubiquitous smartphone cameras can be used to infer SpO$_2$. Most of these works are contact-based, requiring users to cover a phone's camera and its nearby light source with a finger to capture reemitted light from the illuminated tissue. Contact-based methods may lead to skin irritation and sanitary concerns, especially during a pandemic. In this paper, we propose a noncontact method for SpO$_2$ monitoring using hand videos acquired by smartphones. Considering the optical broadband nature of the red (R), green (G), and blue (B) color channels of the smartphone cameras, we exploit all three channels of RGB sensing to distill the SpO$_2$ information beyond the traditional ratio-of-ratios (RoR) method that uses only two wavelengths. To further facilitate an accurate SpO$_2$ prediction, we design adaptive narrow bandpass filters based on accurately estimated heart rate to obtain the most cardiac-related AC component for each color channel. Experimental results show that our proposed blood oxygen estimation method can reach a mean absolute error of 1.26% when a pulse oximeter is used as a reference, outperforming the traditional RoR method by 25%.

Search for physics beyond the standard model in events with two leptons of same sign, missing transverse momentum, and jets in proton-proton collisions at sqrt(s) = 13 TeV

description: A data sample of events from proton-proton collisions with two isolated same-sign leptons, missing transverse momentum, and jets is studied in a search for signatures of new physics phenomena by the CMS Collaboration at the LHC. The data correspond to an integrated luminosity of 35.9 inverse femtobarns, and a center-of-mass energy of 13 TeV. The properties of the events are consistent with expectations from standard model processes, and no excess yield is observed. Exclusion limits at 95% confidence level are set on cross sections for the pair production of gluinos, squarks, and same-sign top quarks, as well as top-quark associated production of a heavy scalar or pseudoscalar boson decaying to top quarks, and on the standard model production of events with four top quarks. The observed lower mass limits are as high as 1500 GeV for gluinos, 830 GeV for bottom squarks. The excluded mass range for heavy (pseudo)scalar bosons is 350-360 (350-410) GeV. Additionally, model-independent limits in several topological regions are provided, allowing for further interpretations of the results.

description: The transverse momentum ($p_{\rm T}$) spectra of inclusive charged particles and its dependence on charged-particle multiplicity are studied in pp collisions at $\sqrt{s}$ = 7 and 13 TeV using the Monte Carlo event generator PYTHIA Monash. The results of the minimum bias pp collisions are compared with the ALICE published results at the same energies. The variations of the effective temperature (T$_{\rm {Eff}}$) and average transverse momentum ($\langle p_{\mathrm{T}} \rangle$) with charged-particle multiplicity are also studied. The $p_{\rm T}$ spectra of the charged particles are observed to get harder with increasing charged-particle multiplicity. Moreover, a sharp increase in the T$_{\rm {Eff}}$ and $\langle p_{\mathrm{T}} \rangle$ with increasing multiplicity followed by a gradual decrease with the further increase in multiplicity could also be observed. Further, it could be observed that the color reconnection (CR) mechanism has a considerable effect on flattening the T$_{\rm {Eff}}$ and $\langle p_{\mathrm{T}} \rangle$ with increasing multiplicity, which indicates that phase-transition may not necessarily be the only mechanism that could give rise to such an effect.

description: We theoretically study the dynamics of skyrmion crystals in electrically-insulating chiral magnets subjected to current-induced spin torques by adjacent metallic layers. We develop an elasticity theory that accounts for the gyrotropic force engendered by the non-trivial topology of the spin texture, tensions at the boundaries due to the exchange of linear and spin angular momentum with the metallic reservoirs, and dissipation in the bulk of the film. A steady translation of the skyrmion crystal is triggered by the current-induced tensions and subsequently sustained by dissipative forces, generating an electromotive force on itinerant spins in the metals. This phenomenon should be revealed as a negative drag in an open two-terminal geometry, or equivalently, as a positive magnetoresistance when the terminals are connected in parallel. We propose non-local transport measurements with these salient features as a tool to characterize the phase diagram of insulating chiral magnets.

description: We continue the study of the gl(1|1) Wess-Zumino-Witten model. The Knizhnik-Zamolodchikov equations for the one, two, three and four point functions are analyzed, for vertex operators corresponding to typical and projective representations. We illustrate their interplay with the logarithmic global conformal Ward identities. We compute the four point function for one projective and three typical representations. Three coupled first order Knizhnik-Zamolodchikov equations are integrated consecutively in terms of generalized hypergeometric functions, and we assemble the solutions into a local correlator. Moreover, we prove crossing symmetry of the four point function of four typical representations at generic momenta. Throughout, the map between the gl(1|1) Wess-Zumino-Witten model and symplectic fermions is exploited and extended.
