description: We discuss KG-oscillators in the (1+2)-dimensional Gürses spacetime and under position-dependent mass (PDM) settings. We observe that the KG-Gürses oscillators are introduced as a byproduct of the very nature of the Gürses spacetime structure. We report that the energy levels of such KG-Gürses oscillators admit vorticity-energy correlations as well as spacetime associated degeneracies (STAD). We discuss KG-Gürses oscillators' results reported by Ahmed \cite{Ahmed1 2019} and pinpoint his improper treatment of this model so that his results should be redirected to those reported in this study. Moreover, we introduce a new set of KG pseudo-Gürses oscillators that admits isospectrality and invariance with the KG-Gürses oscillators and inherits the same vorticity-energy correlations as well as STADs.

description: The digitization of shop floors opens up opportunities for innovative applications and business models due to the vast amount of generated data. However, a lot of this potential is currently not utilized because companies consider the risk of data sharing as too high compared to the corresponding benefit. Focusing on the machine tool sector, the research project MINERVA addresses these concerns by experimentally repurposing privacy-enhancing technologies as confidentialityprotecting technologies and applying them to the use case of condition monitoring to protect intellectual property and other information deemed critical by machine tool operators. Thereby, MINERVA’s goal is to reduce the risk of data sharing and support the establishment of data-driven business models in
the machine tool sector in the long term.

description: Prioritization of threats is an important skill for experts working in the cybersecurity field. With daily new discovered threats and a variety of tools providing information, warnings, and alerts, it is essential for experts working in cybersecurity to identify the most important warnings and threats and handle them efficiently to stay ahead of the growing competence, organization, and size of threat groups. To assist cybersecurity experts with these tasks, this paper provides an approach covering six steps that can be used to determine the efficiency of mitigations for a system under consideration. To this end, this paper describes a straightforward approach and provides an example in which it has already been used.

description: The application of incentives, such as reward and punishment, is a frequently applied way for promoting cooperation among interacting individuals in structured populations. However, how to properly use the incentives is still a challenging problem for incentive-providing institutions. In particular, since the implementation of incentive is costly, to explore the optimal incentive protocol, which ensures the desired collective goal at a minimal cost, is worthy of study. In this work, we consider the positive and negative incentives respectively for a structured population of individuals whose conflicting interactions are characterized by a prisoner's dilemma game. We establish an index function for quantifying the cumulative cost during the process of incentive implementation, and theoretically derive the optimal positive and negative incentive protocols for cooperation on regular networks. We find that both types of optimal incentive protocols are identical and time-invariant. Moreover, we compare the optimal rewarding and punishing schemes concerning implementation cost and provide a rigorous basis for the usage of incentives in the game-theoretical framework. We further perform computer simulations to support our theoretical results and explore their robustness for different types of population structures, including regular, random, small-world, and scale-free networks.

description: Prevailing digital identity solutions are facing widespread dissatisfaction, prompting political and business stakeholders to advocate for the development of novel identity (ID) ecosystems. This paper diverges from the traditional focus on the usability, security, and privacy shortcomings of current solutions, directing attention instead to the economic dimensions that are critical for the successful adoption of digital identity management (IdM) systems. The analysis extends beyond the incentives for end-user adoption, considering the roles, motivations, and ability of other key stakeholders to capture value through the ecosystem, particularly service providers, who are anticipated to be the primary financial contributors to ID services. This examination leads to the pivotal inquiry of whether a market for digital identities can materialize and what strategies for market entry could be viable, especially in scenarios involving public sector participation.

description: Self-Sovereign Identity (SSI) represents a paradigm shift toward user-centric digital identity management by emphasizing principles such as user control and privacy. However, there is a notable gap in assessing how these principles are implemented within existing SSI products despite the ongoing research interest in the theoretical principles of SSI. Our research introduces a structured conformity assessment approach to bridge the gap between theoretical ideals and practical implementation. This approach enables the assessment of SSI products based on fulfilling requirements derived from SSI principles. This provides developers and policymakers with a tool to assess the adherence of SSI products to the fundamental principles. Thus, it may serve developers as a design guideline and policymakers as a basis for certification processes.

description: Curriculum learning (CL) - training using samples that are generated and presented in a meaningful order - was introduced in the machine learning context around a decade ago. While CL has been extensively used and analysed empirically, there has been very little mathematical justification for its advantages. We introduce a CL model for learning the class of k-parities on d bits of a binary string with a neural network trained by stochastic gradient descent (SGD). We show that a wise choice of training examples involving two or more product distributions, allows to reduce significantly the computational cost of learning this class of functions, compared to learning under the uniform distribution. Furthermore, we show that for another class of functions - namely the `Hamming mixtures' - CL strategies involving a bounded number of product distributions are not beneficial.

description: WP3 of the SustainSahel project collects detailed farm household baseline and endline data for two project sites: Koulikouro in Mali and Niakhar in Senegal. This data is mainly used in the context of a randomized controlled trial (RCT) to determine the impact of the project interventions related to improved shrub integration. To select farm households for the surveys in both countries, sample size was determined by power calculations. Based on this, a two-stage cluster sampling procedure was applied at both designated project research areas. Initially approximately 80 villages were sampled from 10 communes and subsequently 7 to 9 farm households were sampled from the selected villages. In Mali, WP3 thus collected a representative dataset with 560 farm household observations at the Koulikoro project site. In Senegal WP3 collected a representative dataset with 720 farm household observations at the Niakhar project site. The baseline data indicate that at both sites there is partial use of agroecological practices (rotations, intercropping, improved fallows, agroforestry), but there is also much scope for boosting adoption and improve existing practices. Many respondents indicated awareness and use of agroforestry in some form or another. Use of shrubs is limited to few species and not systematic. In Koulikoro, mainly productivity benefits are perceived from agroforestry, while in Niakhar soil fertility is the most important perceived benefit.

description: Traffic congestion can have a detrimental effect on public transit systems, and understanding and mitigating these effects is of critical importance for effective public transportation. Implementing Dedicated Bus Lanes (DBLs) is a well-known intervention to achieve this goal. A DBL is a designated lane for bus transit, which avoids congestion and substantially lowers the travel time. This makes transit more attractive, encouraging more travelers to adopt public transportation. This paper studies the impact of congestion and DBLs on novel On-Demand Multimodal Transit Systems (ODMTS). ODMTS combine traditional rail and bus networks with on-demand shuttles. Previous case studies have shown that ODMTS may simultaneously improve travel time, reduce system cost, and attract new passengers. Those benefits were shown for an ideal world without traffic congestion, and this paper hypothesizes that the advantages of ODMTS can be even more pronounced in the real world. This paper explores this hypothesis by creating realistic congestion scenarios and solving bilevel optimization problems to design ODMTS under these scenarios. The impact of DBLs on ODMTS is evaluated with a comprehensive case study in the Metro Atlanta Area. The results show that DBLs can significantly improve travel times and are effective at increasing adoption of the system.

description: A usable analysis tool that provides information on risky app behavior and offers options for action, can contribute to strengthen the digital sovereignty of smartphone app users. To this end, it should be tailored and meet the requirements of a human-centered design. Therefore, we conducted a lab test with N = 38 participants. They evaluated a prototype of our analysis tool in terms of its usability, transparency and potential to increase self-efficacy for data protection and privacy preservation. Furthermore, we investigated the effects of the tailoring by providing a congruent and an incongruent variant for behavioral stages. Both, usability and transparency evaluations differed positively from the average. Moreover, the interaction with the tool
significantly increased the participants' self-efficacy and thus strengthened their digital sovereignty. Our tailoring of texts had a positive impact at least on the efficiency evaluation. This could be further developed by extended tailoring of e.g., the GUI.

description: We study three combinatorial models for the lower-triangular matrix with entries $t_{n,k} = \binom{n}{k} n^{n-k}$: two involving rooted trees on the vertex set $[n+1]$, and one involving partial functional digraphs on the vertex set $[n]$. We show that this matrix is totally positive and that the sequence of its row-generating polynomials is coefficientwise Hankel-totally positive. We then generalize to polynomials $t_{n,k}(y,z)$ that count improper and proper edges, and further to polynomials $t_{n,k}(y,\mathbfϕ)$ in infinitely many indeterminates that give a weight $y$ to each improper edge and a weight $m! \, ϕ_m$ for each vertex with $m$ proper children. We show that if the weight sequence $\mathbfϕ$ is Toeplitz-totally positive, then the two foregoing total-positivity results continue to hold. Our proofs use production matrices and exponential Riordan arrays.

description: The continued operation of the Advanced LIGO and Advanced Virgo gravitational-wave detectors is enabling the first detailed measurements of the mass, spin, and redshift distributions of the merging binary black hole population. Our present knowledge of these distributions, however, is based largely on strongly parameteric models; such models typically assume the distributions of binary parameters to be superpositions of power laws, peaks, dips, and breaks, and then measure the parameters governing these "building block" features. Although this approach has yielded great progress in initial characterization of the compact binary population, the strong assumptions entailed leave it often unclear which physical conclusions are driven by observation and which by the specific choice of model. In this paper, we instead model the merger rate of binary black holes as an unknown \textit{autoregressive process} over the space of binary parameters, allowing us to measure the distributions of binary black hole masses, redshifts, component spins, and effective spins with near-complete agnosticism. We find the primary mass spectrum of binary black holes to be doubly-peaked, with a fairly flat continuum that steepens at high masses. We identify signs of unexpected structure in the redshift distribution of binary black holes: a uniform-in-comoving volume merger rate at low redshift followed by a rise in the merger rate beyond redshift $z\approx 0.5$. Finally, we find that the distribution of black hole spin magnitudes is unimodal and concentrated at small but non-zero values, and that spin orientations span a wide range of spin-orbit misalignment angles but are also moderately unlikely to be truly isotropic.

description: Data exchange is essential in the fast-changing field of data-driven innovations. In exploring the importance of data and data exchange, this paper highlights the necessity of building trust. For data sharing to be successful, trust is essential for assuring reliability, security, and ethical behaviour. We review the current state of the art where research and real-world applications converge in both academia and industry. Notably, trust framework-based projects are starting to take shape, promoting safe and open data markets that are included in this work.
Nonetheless, challenges still exist, such as complex legal, technological, and business issues. Some
of the main challenges that are faced while establishing a trust framework have also been briefly
mentioned in this paper.

description: Consent is a legal basis that legitimizes the processing of personal data under the General Data Protection Regulation (GDPR). Implementing consent management systems in a GDPR-compliant fashion has proven difficult. A major pain point of current implementations is that users only have insufficient means to prove that they withdrew consent. Controllers can, therefore, plausibly deny having received a notification of consent withdrawal and it is thus at their discretion to continue the processing of personal data against the user’s will. As a remedy, it has been proposed to log consent withdrawal events in blockchains to make them non-repudiable by controllers. This approach is typically at odds with the GDPR’s fundamental principle of Storage Limitation. The
issue is that a consent withdrawal event has to permit identification of the user who submitted it, yet only until the controller has received it. However, if they are logged in a blockchain, identification is possible indefinitely, as blockchains are append-only databases that do not facilitate deletion. In the paper at hand, we alleviate this issue and present work in progress on a consent management system in which users (i) give consent by issuing a verifiable credential to a controller and (ii) withdraw consent
by revoking it. These two functions are natively provided in Self-Sovereign Identity (SSI) ecosystems.

State Preparation on Quantum Computers via Quantum Steering

description: One of the major components for realizing quantum computers is the ability to initialize the computer to a known fiducial state, also known as state preparation. We demonstrate a state preparation method via measurement-induced steering on contemporary, digital quantum computers. By delegating ancilla qubits and systems qubits, the system state is prepared by repeatedly performing the following steps: (1) executing a designated system-ancilla entangling circuit, (2) measuring the ancilla qubits, and (3) re-initializing ancilla qubits to known states through active reset. While the ancilla qubits are measured and reinitialized to known states, the system qubits are steered from arbitrary initial states to desired final states. We show results of the method by preparing arbitrary qubit states and qutrit (three-level) states. We also demonstrate that the state convergence can be accelerated by utilizing the readouts of the ancilla qubits to guide the protocol in an active manner. This protocol serves as a nontrivial example that incorporates and characterizes essential operations such as qubit reuse (qubit reset), entangling circuits, and measurement. These operations are not only vital for near-term noisy intermediate-scale quantum (NISQ) applications but are also crucial for realizing future error-correcting codes.

description: Robust and secure trust establishment is an open problem in the domain of self-sovereign identities (SSI). The TRAIN [KR21] concept proposes to leverage the security guarantees and trust anchor of the DNS to publish and resolve pointers to trust lists from DNS. While the DNS is a corner stone of the Internet, its continued use is primarily a consequence of inertia due to its crucial function as the address discovery system for existing Internet services. Research and development in the area of SSI is — for the most part — green field. The choice of DNS as a core building block appears fainthearted given its open security issues. Recently, the IETF paved the way to experiment with alternative name systems in real world deployments by reserving the special-use top-level domain “.alt”
in the domain name space [KH23]. This allows us to use alternative name systems such as the GNU Name System (GNS) [SGF23a] without intruding into the domain name space reserved for DNS. In this paper, we show how we can use the GNS as a drop-in replacement for DNS in TRAIN. We show how TRAIN-over-GNS (GRAIN) can deliver security and privacy improvements the security concept of TRAIN-over DNS and show that it is practically feasible with limited modifications of existing software stacks.

description: This position paper introduces a guided method for experience design that addresses the importance and challenge of considering the rather abstract psychological (user) needs and values as input for creative ideation processes of interactive systems. We present exemplary empirical results from the application of the method concerning the value of privacy, revealing how needs and values can become tangible for user experience designers. Also, interdependencies between the value of privacy and psychological needs, and between the concepts of psychological needs and values in general, were identified by applying the guided experience design method. Learning about the connections of needs and values provide valuable insights for experience design, which are discussed in the paper and should be further explored.

description: Measuring the state of qubits is one of the fundamental operations of a quantum computer. Currently, state-of-the-art high-fidelity single-shot readout of superconducting qubits relies on parametric amplifiers at the millikelvin stage. However, parametric amplifiers are challenging to scale beyond hundreds of qubits owing to practical size and power limitations. Nanobolometers have a multitude of properties that are advantageous for scalability and have recently shown sensitivity and speed promising for qubit readout, but such thermal detectors have not been demonstrated for this purpose. In this work, we utilize an ultrasensitive bolometer in place of a parametric amplifier to experimentally demonstrate single-shot qubit readout. With a readout duration of $13.9~μ\mathrm{s}$, we achieve a single-shot fidelity of 0.618 which is mainly limited by the energy relaxation time of the qubit, $T_1 = 28~μ\mathrm{s}$. Without the $T_1$ errors, we find the fidelity to be 0.927. In the future, high-fidelity single-shot readout may be achieved by straightforward improvements to the chip design and experimental setup, and perhaps most interestingly by the change of the bolometer absorber material to reduce the readout time to the hundred-nanosecond level and beyond.
