description: Phase-resolved spectroscopy of the newly discovered X-ray transient MAXI J0556-332 has revealed the presence of narrow emission lines in the Bowen region that most likely arise on the surface of the mass donor star in this low mass X-ray binary. A period search of the radial velocities of these lines provides two candidate orbital periods (16.43+/-0.12 and 9.754+/-0.048 hrs), which differ from any potential X-ray periods reported. Assuming that MAXI J0556-332 is a relatively high inclination system that harbors a precessing accretion disk in order to explain its X-ray properties, it is only possible to obtain a consistent set of system parameters for the longer period. These assumptions imply a mass ratio of q~0.45, a radial velocity semi-amplitude of the secondary of K_2~190 km/s and a compact object mass of the order of the canonical neutron star mass, making a black hole nature for MAXI J0556-332 unlikely. We also report the presence of strong N III emission lines in the spectrum, thereby inferring a high N/O abundance. Finally we note that the strength of all emission lines shows a continuing decay over the ~1 month of our observations.

Universal Ring Signatures in the Standard Model

description: Ring signatures allow a user to sign messages on behalf of an ad hoc set of users - a ring - while hiding her identity. The original motivation for ring signatures was whistleblowing [Rivest et al. ASIACRYPT’01]: a high government employee can anonymously leak sensitive information while certifying that it comes from a reliable source, namely by signing the leak. However, essentially all known ring signature schemes require the members of the ring to publish a structured verification key that is compatible with the scheme. This creates somewhat of a paradox since, if a user does not want to be framed for whistleblowing, they will stay clear of signature schemes that support ring signatures. In this work, we formalize the concept of universal ring signatures (URS). A URS enables a user to issue a ring signature with respect to a ring of users, independently of the signature schemes they are using. In particular, none of the verification keys in the ring need to come from the same scheme. Thus, in principle, URS presents an effective solution for whistleblowing. The main goal of this work is to study the feasibility of URS, especially in the standard model (i.e. no random oracles or common reference strings). We present several constructions of URS, offering different trade-offs between assumptions required, the level of security achieved, and the size of signatures: Our first construction is based on superpolynomial hardness assumptions of standard primitives. It achieves compact signatures. That means the size of a signature depends only logarithmically on the size of the ring and on the number of signature schemes involved. We then proceed to study the feasibility of constructing URS from standard polynomially-hard assumptions only. We construct a non-compact URS from witness encryption and additional standard assumptions. Finally, we show how to modify the non-compact construction into a compact one by relying on indistinguishability obfuscation.

description: Entamoeba histolytica (Eh) is the causative agent of amebiasis, one of the top four parasitic causes of mortality worldwide. In 90% of infected individuals, Eh harmlessly colonizes the large intestine and results in a non-invasive and asymptomatic infection. In the remaining 10% of infected individuals, the parasite breaches the intestinal barrier causing amebic colitis and in rare cases, it can cause extra-intestinal lesions, mainly liver abscesses. During invasion, Eh encounter macrophages in the lamina propria and this intricate host-parasite interaction is critical in eliciting a tissue damaging raging pro-inflammatory response. When Eh binds macrophages via the Gal-lectin, surface EhCP-A5 ligates α5β1 integrin to activate caspase-1 in a complex known as the NLRP3 inflammasome. In this study, we investigated the parasite requirements underlying macrophage caspase-4 and -1 activation and the role caspase-4 play in augmenting pro-inflammatory cytokine responses. Surprisingly, caspase-4 activation was similar to caspase-1 requiring live Eh attachment via the Gal-lectin, EhCP-A5 and cellular stresses such as K+ efflux and ROS. However, unlike caspase-1, caspase-4 activation was independent of ASC and NLRP3. Using CRISPR/Cas9 gene editing of caspase-4 and caspase-1 in human macrophages, we determined that caspase-1 and bioactive IL-1β release was highly dependent on caspase-4 activation in response to Eh. Formaldehyde cross-linking to stabilize protein-protein interactions in transfected COS-7 cells stimulated with Eh revealed that caspase-4 specifically interacted with caspase-1 in a protein complex that enhanced the cleavage of caspase-1 CARD domains to augment IL-1β release. The mouse ortholog caspase-11, displayed similar requirements for its activation, however, it was not involved in regulating caspase-1 activation in the same way as caspase-4. These findings reveal a novel role for human caspase-4 as a critical sensor molecule to amplify downstream pro-inflammatory responses when macrophage encounters live Eh.

description: We investigate the implications of models that achieve a Standard Model-like Higgs boson of mass near 125 GeV by introducing additional TeV-scale supermultiplets in the vector-like 10+\bar{10} representation of SU(5), within the context of gauge-mediated supersymmetry breaking. We study the resulting mass spectrum of superpartners, comparing and contrasting to the usual gauge-mediated and CMSSM scenarios, and discuss implications for LHC supersymmetry searches. This approach implies that exotic vector-like fermions t'_{1,2}, b',and τ' should be within the reach of the LHC. We discuss the masses, the couplings to electroweak bosons, and the decay branching ratios of the exotic fermions, with and without various unification assumptions for the mass and mixing parameters. We comment on LHC prospects for discovery of the exotic fermion states, both for decays that are prompt and non-prompt on detector-crossing time scales.

description: Aperture arrays have been studied extensively for application in the next generation of large radio telescopes for astronomy, requiring extremely low noise performance. Prototype array systems need to demonstrate the low noise potential of aperture array technology. This paper presents noise measurements for an Aperture Array tile of 144 dual-polarized tapered slot antenna (TSA) elements, originally built and characterized for use as a Phased Array Feed for application in an L-band radio astronomical receiving system. The system noise budget is given and the dependency of the measured noise temperatures on the beam steering is discussed. A comparison is made of the measurement results with simulations of the noise behavior using a system noise model. This model includes the effect of receiver noise coupling, resulting from a changing active reflection coefficient and array noise contribution as a function of beam steering. Measurement results clearly demonstrate the validity of the model and thus the concept of active reflection coefficient for the calculation of effective system noise temperatures. The presented array noise temperatures, with a best measured value of 45 K, are state-of-the-art for room temperature aperture arrays in the 1 GHz range and illustrate their low noise potential.

description: Starting from the first semester, UCN is taking initiatives to progressively implement the concept of internationalization at home (IaH) throughout the course of its physiotherapy programme. The initiatives include research and development activities as well as competency development, thus offering students and staff unique opportunities to interact with international peers. This article aims at describing these IaH implementation initiatives and to show how lecturers, clinical supervisors and students perceive the impact of international strategies on our students’ professional and personal development. We interviewed staff and students who had been in contact with international students in Denmark. In general, lecturers and clinical supervisors report that the IaH initiatives have had a positive impact on local students, emphasizing that they need to be well-prepared before embarking on an exchange period. The students explained how valuable internationalization had been to their professional development and suggested that IaH initiatives could broaden local students’ participation in international exchange experiences.

IBE with Incompressible Master Secret and Small Identity Secrets

description: Side-stepping the protection provided by cryptography, exfiltration attacks are becoming a considerable real-world threat. With the goal of mitigating the exfiltration of cryptographic keys, big-key cryptosystems have been developed over the past few years. These systems come with very large secret keys which are thus hard to exfiltrate. Typically, in such systems, the setup time must be large as it generates the large secret key. However, subsequently, the encryption and decryption operations, that must be performed repeatedly, are required to be efficient. Specifically, the encryption uses only a small public key and the decryption only accesses small ciphertext-dependent parts of the full secret key. Nonetheless, these schemes require decryption to have access to the entire secret key. Thus, using such big-key cryptosystems necessitate that users carry around large secret-keys on their devices, which can be a hassle and in some cases might also render exfiltration easy. With the goal of removing this problem, in this work, we initiate the study of big-key identity-based encryption (bk-IBE). In such a system, the master secret-key is allowed to be large but we require that the identity-based secret keys are short. This allows users to use the identity-based short keys as the ephemeral secret keys that can be more easily carried around and allow for decrypting ciphertexts matching a particular identity, e.g. messages that were encrypted on a particular date. In particular: We build a new definitional framework for bk-IBE capturing a range of applications. In the case when the exfiltration is small our definition promises stronger security—namely, an adversary can break semantic security for only a few identities, proportional to the amount of leakage it gets. In contrast, in the catastrophic case where a large fraction of the master secret key has been ex-filtrated, we can still resort to a guarantee that the ciphertexts generated for a randomly chosen identity (or, an identity with enough entropy) remain protected. We demonstrate how this framework captures the best possible security guarantees. We show the first construction of such a bk-IBE offering strong security properties. Our construction is based on standard assumptions on groups with bilinear pairings and brings together techniques from seemingly different contexts such as leakage resilient cryptography, reusable two-round MPC, and laconic oblivious transfer. We expect our techniques to be of independent interest.

description: The development of cracks and corrosion in pipelines could pose a potential hazard to the community and the pipeline industry. Particularly for buried or insulated pipelines, corrosion and other types of defects may remain invisible unless the pipe is physically excavated or the insulation layers are removed. In this regard, advanced guided wave techniques are rapidly growing due to the advantages that they offer over traditional direct assessment inspection methods. To overcome the challenges associated with the use of conventional ultrasonic techniques, a non-contact laser-based non-destructive evaluation system is proposed in this research work. Compared to conventional ultrasonic transducers, a laser-based technique remains functional at elevated temperatures and can result in high-resolution damage visualization. Using the laser Doppler vibrometer as the ultrasonic detection subsystem, and the pulsed Nd:YAG laser for the ultrasonic generation, a complete non-contact ultrasonic system was implemented. The pulsed laser heats the surface of the specimen, and as a result, thermal and ultrasonic waves are generated in the structure. A reliable numerical model was created using the finite element analysis. The numerical results were validated with experiments in the time and frequency domains. The application of a Nd:YAG laser for ultrasonic wave generation was limited due to a lack of repeatability in the signals and low signal-to-noise ratio and potential damages to the surface. Instead, a piezoelectric transducer in combination with the laser Doppler vibrometer was used to enhance defect identification in aluminum plates. The results show that the proposed method can successfully identify the location and the approximate shape of hidden defects.

description: This paper aims to provide insight into and compare the existing Internationalisation at Home (IaH) practices in two international business programmes offered by University College of Northern Denmark (UCN), to this end analysing both their formal and their informal curricula (Leask, 2009; 2016). This comparative case study relies on qualitative data collection methods. Its findings show that the faculty is committed to internationalisation, but lacks a holistic IaH vision and consistent IaH practices. The paper offers practical suggestions for enhancing the programmes’ IaH activities within the existing curricular structures. The suggestions could be applied to other international programmes at UCN or to other university colleges (professionshøjskoler) in Denmark.

Efficiently Factorizing Boolean Matrices using Proximal Gradient Descent

Publisher: name: CISPA
Year: 2023

description: Addressing the interpretability problem of NMF on Boolean data, Boolean Matrix Factorization (BMF) uses Boolean algebra to decompose the input into low-rank Boolean factor matrices. These matrices are highly interpretable and very useful in practice, but they come at the high computational cost of solving an NP-hard combinatorial optimization problem. To reduce the computational burden, we propose to relax BMF continuously using a novel elastic-binary regularizer, from which we derive a proximal gradient algorithm. Through an extensive set of experiments, we demonstrate that our method works well in practice: On synthetic data, we show that it converges quickly, recovers the ground truth precisely, and estimates the simulated rank exactly. On real-world data, we improve upon the state of the art in recall, loss, and runtime, and a case study from the medical domain confirms that our results are easily interpretable and semantically meaningful.

description: I denne artikel præsenteres en kvalitativ semistruktureret fokusgruppeundersøgelse blandt udvekslingsstuderende, som har valgt at studere på læreruddannelsen (LU), Professionshøjskolen UCN (UCN). Artiklens fokus er primært på uddannelsens læringsmiljø med udgangspunkt i de studerendes perspektiver på, hvordan og i hvor høj grad miljøet virker inkluderende. Der tages afsæt i en teoretisk ramme inspireret af Bourdieus uddannelsessociologi og Leasks perspektiver på det formelle, uformelle og skjulte curriculum, herunder dets muligheder og begrænsninger i forhold til adgang til læring og inklusion fra et internationaliseringsperspektiv. Den væsentligste konklusion er, at denne gruppe studerende ofte føler sig overset på LU, da der kun stilles mangelfuld engelsksproget information til rådighed, og al anden information, der sendes til de studerende via e-mail, er på dansk. Desuden synes manglen på et internationaliseret curriculum i undervisningen at udfordre et inkluderende læringsmiljø for alle. Dette skyldes formodentlig, at der overordnet arbejdes med danske undervisningsplaner og uddannes til en national kontekst. Det ser ud til, at udsatheden af de internationale studerende øges, da deres viden og erfaring kun i meget begrænset omfang bringes i spil i nuværende strukturer, læringsmål og studieordning. Konsekvensen heraf er, at denne gruppe har svært ved at bidrage aktivt og finde deres ståsted, bl.a. i gruppearbejdet. Artiklen rundes af med en diskussion samt forslag til, hvordan et mere inkluderende læringsmiljø kunne realiseres ved en større bevidsthed om behovet for at eksemplificere og internationalisere i undervisningen samt igangsætte forskningsinitiativer for derved at bidrage aktivt til “Internationalisation at Home” (IaH) på LU.

description: Abstract

The study entitled "The Impact of Organizational Justice on Human Resources Satisfaction (Model of "Sports Federations in the Kingdom of Bahrain")" explores the extent of the impact of organizational justice by knowing the nature of the relationship between the study variables and their extent of association with sports federations in the Kingdom of Bahrain as a model. To reach the goal of the study, the researcher decided to follow the descriptive analytical approach by using a questionnaire that includes the study variables (organizational justice and job satisfaction of human resources) for the study community consisting of (1500) human resources working in the sports federations of the Kingdom of Bahrain. The study sample was selected from the study community, which consists of (288) human resources, or (20%) of the original community size, where Likert scale of five levels was used to answer the questionnaire. The researcher reached a set of results, which consisted of 10 results, the most important of which is (the satisfaction of human resources in sports federations is affected by the level of organizational justice practiced in sports federations in the Kingdom of Bahrain in general and distributive justice in particular), the study also recommended the need of the incentive distribution system to a continuous develop that aims to focus on the efforts of human resources in sports federations in the Kingdom of Bahrain directly and tangibly, and therefore incentives must be linked to the performance of human resources, in addition to other recommendations.
The relations between children's communicative perspective-taking and executive functioning

description: Bibliography: p. 81-87
description: This research investigated young children's ability to use the perspective of their communicative partner to guide their production and interpretation of referential statements. The cognitive skills associated with successful perspective-taking in referential communication were also examined. In Experiment 1, 4.5- to 5.5-year-old children were tested on two referential communication tasks during which they had to either instruct an experimenter to pick up an object (production task) or follow instructions to retrieve an object (comprehension task). They were also administered measures of inhibitory control, working memory, and cognitive flexibility. Results indicate that children used the perspective of their speaking partner to guide their communicative behaviours in both the production and communication tasks. However, children did not completely disregard their own perspective during the production and interpretation of statements. Egocentric interpretations of speaker requests were negatively correlated with children's inhibitory control skills. No other dimensions of executive function skills related to children's communicative perspective-taking. These findings suggest that children's inhibitory control skills relate to their ability to inhibit their own perspective during communicative interactions. In Experiment 2, 3.5- to 4.5-year-old children were tested on the same comprehension task used in Experiment 1. To further explicate the relation between inhibitory control skills and children's use of another perspective when interpreting statements, preschoolers were administered measures of delay inhibition and conflict inhibition. Preschoolers' egocentric processing of the speaker's requests were related to their performance on the conflict inhibitory control tasks, whereas their simultaneous choice of both an object visible and blocked from the speaker's view was related to their performance on the delay inhibitory control tasks. The results of these studies suggest young children can differentiate between information that is accessible to the speaker versus information that is available only to them, and, moreover, they can use this information to guide their communicative behaviours. Furthermore, the results suggest that children's developing inhibitory control skills allow them to inhibit their own perspective, enabling them to make use of their communicative partner's perspective.

description: Den videregående uddannelsessektor i Danmark har i mange år arbejdet strategisk og målrettet med sin internationaliseringsindsats, særligt i forhold til den udgående studenter- og medarbejdermobilitet. Ikke desto mindre må vi på professionshøjskolerne erkende, at det er en udfordring at få de studerende på mange af velfærdsuddannelserne til at rejse ud, blandt andet med det formål at udvikle sproglige og interkulturelle kompetencer. Kigger vi ind i fremtiden, er der ikke noget i de professionsbachelorstuderendes adfærd, som antyder, at udlandsophold vil blive det nye sort, og med en forstærket tilbageholdenhed oven på den aktuelle coronapandemi er der behov for øget fokus på andre internationaliseringsindsatser end den udgående mobilitet. Internationalisation at Home (IaH) bliver i den forbindelse vigtigt, da fænomenet netop er et forsøg på at skabe en international kultur i det lokale læringsmiljø, men det skal både indtænkes i den enkelte uddannelse og i hele institutionens strategiske internationaliseringsarbejde, hvis det for alvor skal brænde igennem til de studerende.

This class can be characterized by the Fourier transform which has a power series expansion including real powers, not only integer powers. This class includes stable distributions in probability and also non-commutative probability theories. We also characterize the class in terms of the Cauchy-Stieltjes transform and the Voiculescu transform. If the stability index is greater than one, stable distributions in probability theory do not belong to that class, while they do in non-commutative probability.

Many reasons lead to resource inadequacy, including demand flaws, the missing money problem, poor coordination by investors, and penetration of renewables. In order to ensure resource adequacy in the long run, the energy-only market requires a new market mechanism to incentivize investors to create more new capacity. The thesis mainly analyzes three possible solutions: a capacity market, increase of the price cap up to the value of lost load (VOLL) in the energy-only market (Scarcity Pricing), and a single buyer model.

description: The behavior of command-line utilities can be very much influenced by passing command-line options and arguments—configuration settings that enable, disable, or otherwise influence parts of the code to be executed. Hence, systematic testing of command-line utilities requires testing them with diverse configurations of supported command-line options. We introduce CLIFuzzer, a tool that takes an executable program and, using dynamic analysis to track input processing, automatically extract a full set of its options, arguments, and argument types. This set forms a grammar that represents the valid sequences of valid options and arguments. Producing invocations from this grammar, we can fuzz the program with an endless list of random configurations, covering the related code. This leads to increased coverage and new bugs over purely mutation based fuzzers.

description: The demand for higher speed and reliability for wireless LAN (WLAN) has pushed the industry to introduce new standards in the market such as IEEE 802.11 n. This future standard makes use of MIMO and OFDM to provide higher reliability at higher speeds. This thesis presents a practical performance analysis of a MIMO and OFDM based WLAN, with the help of actual measurements which have been taken at residential and office locations. The performance impact of an OFDM parameter i.e. the length of cyclic prefix (CP) has been studied through capacity analysis and effort has been made to optimize the CP length. The effect of different number of antenna combinations on the performance of MIMO capacity has been analysed. This analysis also includes effect of antenna array orientation and increasing correlation between the antennas. Conclusions have been derived from the results of the analysis for the optimum choice of the parameters.
The interaction of visible and infrared radiation with molecular and metallic particles

description: In this thesis, the electromagnetic spectra of both conducting and non-conducting particles are studied. The relationship between particle shape and spectra is explored through both modeling and experiments. Depending on the situation, spectra are modeled using techniques such as the discrete dipole approximation, the vibrational exciton model, various electrostatic methods, or density functional theory. These results are used to not only characterize the particles in the system of interest, but also understand how particle architecture influences its spectrum. Furthermore, it is demonstrated how the consideration of a particle's symmetry, and when appropriate the symmetry of the crystal structure that forms a particle, can greatly simplify the interpretation of spectra. The main systems studied in this work are Au nanoparticles and molecular aerosol particles composed of either pure C₂H₂, pure CO₂, mixtures of pure C₂H₂ and pure CO₂ or co-crystalline CO₂·C₂H₂. The molecular aerosol particles that are studied here were chosen due to their relevance to many planetary atmospheres. Several questions concerning the phase and shape of these molecular particles are addressed and answered. Finally, the similarities between the electromagnetic response of conducting and non-conducting particles are discussed at several points in this thesis. Hybridization schemes are shown to be a powerful tool for understanding the spectra of complex nanostructures. These schemes involve decomposing complex structures into primitive components. Spectra can then be understood as mixtures of the spectra of these primitive components. For the first time a formalism is developed that allows for such hybridization methods to be extended to non-conducting particles.

State Machine Replication under Changing Network Conditions

description: Protocols for state machine replication (SMR) are typically designed for synchronous or asynchronous networks, with a lower corrup- tion threshold in the latter case. Recent network-agnostic protocols are secure when run in either a synchronous or an asynchronous network. We propose two new constructions of network-agnostic SMR protocols that improve on existing protocols in terms of either the adversarial model or communication complexity: 1. an adaptively secure protocol with optimal corruption thresholds and quadratic amortized communication complexity per transaction; 2. a statically secure protocol with near-optimal corruption thresholds and linear amortized communication complexity per transaction. We further explore SMR protocols run in a network that may change between synchronous and asynchronous arbitrarily often; parties can be uncorrupted (as in the proactive model), and the protocol should remain secure as long as the appropriate corruption thresholds are maintained. We show that purely asynchronous proactive secret sharing is impossible without some form of synchronization between the parties, ruling out a natural approach to proactively secure network-agnostic SMR protocols. Motivated by this negative result, we consider a model where the ad- versary is limited in the total number of parties it can corrupt over the duration of the protocol and show, in this setting, that our SMR proto- cols remain secure even under arbitrarily changing network conditions.

Eﬀicient Adaptively-Secure Byzantine Agreement for Long Messages

Publisher: name: CISPA

description: We investigate the communication complexity of Byzantine agreement protocols for long messages against an adaptive adversary. In this setting, prior $n$-party protocols either achieved a communication complexity of $O(nl\cdot\poly(\kappa))$ or $O(nl + n^2 \cdot \poly(\kappa))$ for $l$-bit long messages and security parameter $\kappa$. We improve the state of the art by presenting protocols with communication complexity $O(nl + n \cdot \poly(\kappa))$ in both the synchronous and asynchronous communication models. The synchronous protocol tolerates $t \le (1-\epsilon) \frac{n}{2}$ corruptions and assumes a VRF setup, while the asynchronous protocol tolerates $t \le (1-\epsilon) \frac{n}{3}$ corruptions under further cryptographic assumptions. Our protocols are very simple and combine subcommittee election with the recent approach of Nayak et al. (DISC `20). Surprisingly, the analysis of our protocols is \emph{all but simple} and involves an interesting new application of Mc Diarmid's inequality to obtain {\em almost optimal} corruption thresholds.

description: Current results of the MiniBooNE experiment show excess events that indicate neutrino oscillations, but only if one goes beyond the standard 3 family scenario. Recently a different explanation of the events has been given, not in terms of oscillations but by the production and decay of a massive sterile neutrino with large transition magnetic moment. We study the effect of such a sterile neutrino in the rare decays $τ^- \rightarrow μ^- μ^+ π^- ν$ and $τ^{-}\rightarrow μ^{-} μ^{+} e^{-} νν$. We find that searches for these decays featuring displaced vertices between the $μ^-$ and the other charged particles, constitute good tests for the existence of the sterile neutrino proposed to explain the MiniBooNE anomaly. These searches could be done with already existing experimental data.
