description: Reproductive technologies could be markedly improved by the development of methods to evaluate oocyte and/or embryo quality in a non-invasive, quantitative manner. Previous work from this lab has shown that human embryos secrete factors that inhibit progesterone and estradiol production by granulosa cells. To determine if the presence of the progesterone-inhibitory factor (PIF) and estradiol-regulatory factor in human embryo-conditioned (HEC) media correlates with the health and developmental capacity of the embryos, an interspecies bioassay was established. Oocyte-cumulus complexes were isolated from superovulated mouse ovaries, the oocytes were microsurgically removed and the oocytectomized complexes were cultured in (HEC) media for 48 hours in the presence of FSH and testosterone. Steroid accumulation in the media was determined by radioimmunoassay. Despite the potential limitations of very small volumes of HEC media to evaluate, and the need to freeze this media at the source, the bioassay was able to detect PIF activity in HEC media, but no success was achieved measuring estradiol-regulatory factor. Most embryos produced PIF activity, but the degree of inhibition did not correlate with the ability of the oocytes to be fertilized nor with embryo morphology or their ability to cleave and develop after transfer. The role of the oocyte-specific protein, growth differentiation factor-9 (GDF-9), in cumulus expansion and steroidogenesis was also investigated to determine its potential as a marker for oocyte and embryo quality. Results with (HEC) media demonstrated that the secretion of PIF by human embryos could be measured by this bioassay and that human PIF could inhibit murine granulosa cell steroidogenesis; however, PIF activity did not correlate with human embryo quality or developmental competence. GDF-9 was shown to enable cumulus expansion and inhibit progesterone and stimulate estradiol production by murine cumulus granulosa cells.

Linear regression with spatially correlated data.

Subjects: subject: Statistics.

description: In this dissertation, the analysis of spatial data through regression is investigated. Multiple observations taken from sites are assumed to be spatially dependent. Our linear model includes a pure error and a spatial error term whose covariance structure is given by an unknown linear combination of 2 known covariograms. The pure and spatial error terms also have separate scale parameters. Our first concern is with the estimation of the parameters of this model. An algorithm to estimate these parameters is proposed as well as a consistent estimator for one of the spatial parameters. Numerical simulations support the use of our algorithm. The second main issue is that of asymptotics. To that end, a formula for the inverse of the variance-covariance matrix of observations is developed. Limits of the asymptotic variance of the parameter estimates as the number of observations per site increases are found with this formula. On the other hand, specific sampling schemes are studied when considering the asymptotics for the number of sites going to infinity. From the simulation and asymptotic results, some rules for experimental design are given. Extensions to more general models are made and areas of future research including possible applications are suggested.

description: Head injuries are a major cause of morbidity and mortality worldwide, many resulting from sporting activities. Currently, there is a need in the head protection industry for improved technology capable of reducing the risk of mild and severe head injuries. Contemporary head protection devices are comprised mainly of foam and have several inherent disadvantages, including a limited ability to provide effective energy absorption under both low and high impact velocities. New thin-walled collapsible chamber energy absorption systems may resolve this problem. The chambers consist of four engineering elements which alter their performance - geometry, air volume, material, and venting system. This research analyzed the contribution of air flow through an orifice to the chamber's management of impact energy. The main objective of the study was to determine the effect of the chamber's vent diameter on peak force and venting rate during an impact. Two material stiffnesses and five vent diameters were tested at three inbound velocities. Each chamber was impacted ten times using a monorail drop system. Significant main effects were found for material stiffness, vent diameter, and inbound velocity on peak force and venting rate (p<0.0001). Under low inbound velocities the largest vent diameters transmitted less force than the smallest, while this relationship reversed at high inbound velocities. Under low velocities air flow rate was negatively, and flow duration was positively correlated to peak force. Under high velocities, air flow rate was positively, and duration was negatively correlated to peak force. This suggested that under low velocities chambers performed optimally when air was dissipated fast, for a short duration; however, as the chamber approached a critical failure region, the increased duration and decreased velocity of air released prevented larger peak forces. Overall, this research confirmed that engineered thin-walled collapsible chambers use air as a mechanism to absorb impacting force.

description: A new model of Alpine mountain-building based on state-of-the-art seismic imaging explains how slab delamination and detachment facilitated indentation and led to along-strike changes in orogenic structure, denudation and basin dynamics. After Adria-Europe plate collision (40–32 Ma), slab steepening and delamination of the European slab changed the taper angle of the orogenic wedge in the Central Alps as the subduction singularity migrated northward. This induced rapid exhumation and denudation of the Lepontine orogenic core, accompanied by waves of clastic deposition in the overfilled western foreland basin. In the Eastern Alps, the heavier part of the slab delaminated further northward, driving prolonged subsidence and marine sedimentation in the underfilled eastern foreland basin. At ~ 20 Ma, the slab segment beneath the Eastern Alps detached, facilitating fragmentation of the indenting northern edge of the Adriatic Plate. This offset the collisional edifice while reorganizing subduction singularities and bifurcating drainage divides. Slab detachment triggered rapid uplift and terrigenous filling of the eastern foreland basin, together with orogen-parallel extrusion of the rapidly exhuming Tauern orogenic core toward the Pannonian Basin. There followed a dramatic shift in thrust-activity and -vergence from northward to southward. Similar lateral variations are documented for other orogens experiencing slab delamination and detachment.

description: Background Parents play a central role for transgender adolescents’ well-being and their coping with minority stress, like discrimination, rejection and violence. Yet, little is known about the experiences of parents facing minority stress as they support their transgender children who are either awaiting or undergoing medical transition. Therefore, we aimed to first examine minority stress experiences reported by the parents with respect to distal and proximal stressors. Second, we aimed to explore whether experiences relate to children’s stress experiences as secondary stress experiences, or if parents report minority stress directed at themselves as primary stress experiences. Methods In the context of the participatory TRANS*PARENT study in Berlin, Germany, from April 2022 to September 2022 five focus groups were conducted with a total of 24 parents who have a transgender and/or non-binary child at the age of 11–18 years. Qualitative structuring content analysis was applied. Results Parents reported distal stressors such as structural problems (in education, medical, psychiatric and psychological institutions, leisure activities and sports) and social rejection (peer rejection like bullying and violence, gaslighting, intersectionality, blame of others). Proximal stressors covered fears of future/anticipated discrimination, internalized gender stereotypes, and self-blame. Most experiences were secondary stressors, related to the child’s minority stress causing frustration and sadness for the parents, while especially fears of the future/anticipated discrimination, gaslighting and blame of others emerged as central primary stressors. Discussion Results show a complex interaction of minority stressors affecting both parents and their transgender children on structural and social levels. The impairment of their child’s education and worries about its safety and life prospects burdened parents the most. The additional direct and primary stress experiences might impede their efforts to navigate their child’s transition process. Conclusion In transgender health care, the multidimensionality of the structural and social impacts of marginalization needs to be addressed not only with respect to the transgender adolescents themselves, but also with respect to their caregivers. Further research should explore how child and parental stress interact and how family-based health care can alleviate stress on both child and parent level.
A conversation on the efficacies of the game engine to address notions of sacred space: the digital songlines project and transgressions of sacredness

description: The Digital Songlines (DSL) game engine is used as a vehicle for Indigenous Australian storytelling. Their storytelling is inextricably linked to the 'country' from which it emerges. The game engine provides a simulation of that country for embedding of the stories to be told. Much of the 'country' referred to is sacred. However, the fundamental underlying principles of threedimensional reproduction of space in a 3D computer game (3DCG) defines all spaces as mathematically equal - there is no place for notions of sacred spaces. This presents a dilemma for those cultures that do not subscribe to the scientific notions of ontological certainty underpinning such mathematically modelled space. In the case of the DSL game engine, notions of the sacredness of the country modelled has been made explicit in order to highlight its importance for its physical-world corollary. Hence, this paper discusses notions of sacredness and its place in the simulational spaces of the DSL's 3DCG engine. It presents a series of dilemmas for the inclusion of sacred places in simulational spaces. It does not attempt to resolve these dilemmas, but rather to bring them into sharp relief with examples drawn from the DSL project experience. In so doing, it presents a new way of thinking through the significance of this issue for Western and non-Western use of the 3DCG in cultural heritage applications.

description: In this study, we compared a monocular computer vision (MCV)-based approach with the golden standard for collecting kinematic data on ski tracks (i.e., video-based stereophotogrammetry) and assessed its deployment readiness for answering applied research questions in the context of alpine skiing. The investigated MCV-based approach predicted the three-dimensional human pose and ski orientation based on the image data from a single camera. The data set used for training and testing the underlying deep nets originated from a field experiment with six competitive alpine skiers. The normalized mean per joint position error of the MVC-based approach was found to be 0.08 ± 0.01 m. Knee flexion showed an accuracy and precision (in parenthesis) of 0.4 ± 7.1° (7.2 ± 1.5°) for the outside leg, and −0.2 ± 5.0° (6.7 ± 1.1°) for the inside leg. For hip flexion, the corresponding values were −0.4 ± 6.1° (4.4° ± 1.5°) and −0.7 ± 4.7° (3.7 ± 1.0°), respectively. The accuracy and precision of skiing-related metrics were revealed to be 0.03 ± 0.01 m (0.01 ± 0.00 m) for relative center of mass position, −0.1 ± 3.8° (3.4 ± 0.9) for lean angle, 0.01 ± 0.03 m (0.02 ± 0.01 m) for center of mass to outside ankle distance, 0.01 ± 0.05 m (0.03 ± 0.01 m) for fore/aft position, and 0.00 ± 0.01 m2 (0.01 ± 0.00 m2) for drag area. Such magnitudes can be considered acceptable for detecting relevant differences in the context of alpine skiing.

description: This paper reports on a major Australian research project which examines whether the evolution in digital content creation and social media can create a new audience of active cultural participants. The project draws together experts from major Australian museums, libraries and screen centres to examine the evolution in digital content creation and social media. It explores whether organizations can become active in content generation ('new literacy'), and thereby be linked into new modes of distribution, calling into being 'new audiences'. The paper presents interim findings of the project, describing the theories and methodologies developed to investigate the rise of social media and, more broadly, digital content creation, within cultural institutions.
A socio-rhetorical analysis of the Lukan narrative of the Last Supper.

description: In light of socio-rhetorical criticism, Luke's LS account emerges as rhetorical discourse both by its many Hellenistic rhetorical features and in terms of their underlying premise. Luke 22:7--38 (Western Text) clearly functions as a rhetorical discourse meant to alter the social expectations of Luke's community and produce corresponding changes in its conduct. In Chapter One, we review the history of interpretation of the Lukan LS text and provide justification for the present study. We define the aim and present our research methodology. Here we suggest that Luke achieves his self-interest, as we have defined it, by constructing his LS as a rhetorical elaboration of theme. Treating Luke's LS as a rhetorical elaboration reveals that Luke 22:7--38 (Western Text) is a unified text. In Chapter Two, we define our textual unit as the Western Text (WT) and not the Alexandrian Text (AT) of Luke's LS. Here I show how Luke crafted his elaboration by looking at the narrative material, argumentation, and repetition. Chapter Three shows that from the perspective of socio-rhetorical analysis there are four ways a text may use antecedent texts, oral or written, namely, recitation, reconfiguration, recontextualisation, and oral-scribal echo. Luke in composing his LS has reworked specific oral as well as written traditions available to him. In Chapter Four we explore Luke's dependence on the cultural systems and social structure in his contemporary Mediterranean society. This interaction with certain social codes and cultural scripts in the first-century Mediterranean leads me to conclude in Chapter Five that the language in the text can be social-culturally located as a first-century Mediterranean revolutionist response, with a conversionist tendency, that seeks to reconstruct the old social order for the purposes of establishing a new social order, the kingdom of God, the kind of primitive "Christian" community Luke describes in the first chapters of Acts. The sixth chapter explores how this social and cultural program reflects sacred interests. The concluding chapter combines exploration of the ideology of our chosen text with a resume of the course of our investigation. Our exploration of ideological texture identifies the ideology of the implied author and shows just how this ideology shapes the narrative of the Lukan LS. (Abstract shortened by UMI.)

description: This paper describes the measurement of collective flow for charged particles in Au+Au collisions at sqrt{s_NN}} = 130 GeV using the PHOBOS detector at the Relativistic Heavy Ion Collider (RHIC). An azimuthal anisotropy is observed in the charged particle hit distribution in the PHOBOS multiplicity detector. This anisotropy is presented over a wide range of pseudorapidity (eta) for the first time at this energy. The size of the anisotropy (v_{2}) is thought to probe the degree of equilibration achieved in these collisions. The result here,averaged over momenta and particle species, is observed to reach 7% for peripheral collisions at mid-rapidity, falling off with centrality and increasing |eta|. Data are presented as a function of centrality for |eta|<1.0 and as a function of eta, averaged over centrality, in the angular region -5.0

description: Atmospheric nitrogen (N) pollution is considered responsible for a substantial decline in plant species richness and for altered community structures in terrestrial habitats worldwide. Nitrogen affects habitats through direct toxicity, soil acidification, and in particular by favoring fast-growing species. Pressure from N pollution is decreasing in some areas. In Europe (EU28), overall emissions of NO x declined by more than 50% while NH3 declined by less than 30% between the years 1990 and 2015, and further decreases may be achieved. The timescale over which these improvements will affect ecosystems is uncertain. Here we use 23 European forest research sites with high quality long-term data on deposition, climate, soil recovery, and understory vegetation to assess benefits of currently legislated N deposition reductions in forest understory vegetation. A dynamic soil model coupled to a statistical plant species niche model was applied with site-based climate and deposition. We use indicators of N deposition and climate warming effects such as the change in the occurrence of oligophilic, acidophilic, and cold-tolerant plant species to compare the present with projections for 2030 and 2050. The decrease in N deposition under current legislation emission (CLE) reduction targets until 2030 is not expected to result in a release from eutrophication. Albeit the model predictions show considerable uncertainty when compared with observations, they indicate that oligophilic forest understory plant species will further decrease. This result is partially due to confounding processes related to climate effects and to major decreases in sulphur deposition and consequent recovery from soil acidification, but shows that decreases in N deposition under CLE will most likely be insufficient to allow recovery from eutrophication.

Australian public housing and the diverse histories of social mix
Creators: name: Arthurson, Kathy
Publisher: name: Swinburne
Year: 2024

description: In Australia, the concept of social mix has strong currency in contemporary public housing estate regeneration policy, where balancing social mix is attached to addressing social and behavioral issues on the postwar public housing estates. However, contemporary debates about social mix tend to ignore the finding that interest in social mix is by no means new. Attention to social mix has informed Australian new town planning and housing policy since the post–World War II years, although the origins of the concept can be seen earlier in mid-nineteenth-century Britain. The focus of this article is on examining the relevance of the concept of social mix through history by drawing on South Australian housing policy and the Salisbury North housing estate as a specific case study of social mix in practice. The aim is to show how the concept of social mix is constructed differently over time and how it has been adapted to the present situation of dealing with concentrations of impoverished residents on public housing estates. The article draws on context, practice, and texts as important variables that help to constitute the meaning of social mix.

description: Background: Radiology integration into medical anatomy courses is well established, but there is a paucity of literature on integrating virtual dissection into cadaveric dissection laboratories. Virtual dissection is the digital dissection of medical images on touchscreen anatomy visualization tables. The purpose of this pilot study was to investigate the feasibility of integrating virtual dissection into a first-year medical cadaver-based anatomy course and to assess students’ overall attitude towards this new technology. Methods: All students in first-year medicine at a single medical school participated in this study (n = 292). Six virtual dissection laboratories, which focused on normal anatomy, were developed and integrated into a cadaver-based anatomy course. The virtual dissection table (VDT) was also integrated into the final anatomy spot exam. Following the course, students completed a short evidence-informed survey which was developed using a theoretical framework for curriculum evaluation. Numerical data were tabulated, and qualitative content analysis was performed on students’ unstructured comments. Results: The survey response rate was 69.2% (n = 202/292). Most (78.7%) students reported that virtual dissection enhanced their understanding of the cadaveric anatomy and the clinical applications of anatomy. Most (73.8%) students also felt that the VDT was an effective use of the laboratory time. Thirteen narrative comments were collected, most of which (61.5%) identified strengths of the curriculum. Conclusions: In this pilot study, students perceived that their learning was enhanced when virtual dissection was combined with a cadaver-based anatomy laboratory. This study demonstrates that there is potential for virtual dissection to augment cadaveric dissection in medical education.

description: The aim of this paper is to show the contribution of postcolonial and decolonial approaches to the interpretation of Foucauldian discursivity, in terms of its use as a conceptual toolbox for the study of political events in regions where colonial domination structures still survive. Both of these approaches argue that Foucault´s thought leaves Eurocentrism intact simply because it doesn’t consider the “colonial difference” as constitutive of modernity, biopower and governmentality. Nevertheless, post- and de-colonial perspectives consider that his theoretical framework has played a positive role in studies carried out from the European periphery.

Sin embargo, no niegan los aportes que realiza el autor francés para los estudios desde la periferia europea.

description: Atmospheric CO2 measurements are important in understanding the global carbon cycle and in studying local sources and sinks. Ground and satellite-based measurements provide information on different temporal and spatial scales. However, the compatibility of such measurements at single sites is still underexplored, and the applicability of consistent data processing routines remains a challenge. In this study, we present an inter-comparison among representative surface and column-averaged CO2 records derived from continuous in-situ measurements, ground-based Fourier transform infrared measurements, satellite measurements, and modeled results over the Mount Zugspitze region of Germany. The mean annual growth rates agree well with around 2.2 ppm yr-1 over a 17-year period (2002-2018), while the mean seasonal amplitudes show distinct differences (surface:11.7 ppm/column-averaged: 6.6 ppm) due to differing air masses. We were able to demonstrate that, by using consistent data processing routines with proper data retrieval and gap interpolation algorithms, the trend and seasonality can be well extracted from all measurement data sets.

description: At War with Itself: Rutgers University’s Student Led Movements for Progressive Reform and the Boundaries of Hegemony, 1965-1972 is a thesis which questions the limitations put on progressive movements by the hegemony of the society and the various elements of institutional and systemic power which historically support and maintain the structures of societal power. Utilizing the theory of hegemony first posed by the Italian Marxist Communist Antonio Gramsci and his works on the topic, along with an extensive use of Rutgers own archives, and a range of secondary sources dealing with everything from the periods economy, educational practices, and social formations in an effort to produce an accurate analysis of these various elements of United States (US) hegemony for this thesis. A micro analysis focusing on key events which took place on Rutgers three campuses during the 1965-1972 period, and the final years of President Mason W. Gross’s tenure at the University. This thesis does not set out to prove anything, but instead to accurately illustrate the ways in which power and the system of capitalism remain entrenched as the dominant modes of societal and economic organization in spite of the contradictions produced by both capitalism and the current power structures of the US. This automatic and largely unconscious defense of entrenched power takes on an almost incalculable amount of forms some of which this thesis analyzes more closely, such as mass media, political leadership, and institutional authority. In total, this work remained dedicated to illustrating the effects of hegemony on US society through the lens of campus activity on Rutgers campuses during the 1965-1972 period.

description: The paper discusses the biopolitical strategies of marginalization founded on the proclamation of the state of exception and on the exercise of violence as an instrument of power. It invites to consider Rio de Janeiro favelas as paradigmatic cases to probe into the practices of resistance to the policies of inclusive exclusion managed by State governmentality and by criminal normation. It considers the favelas as laboratories of new forms of subjectivity, which rethink the relations among the individual, the State and the Nation and promote new models of citizenship based on the participation to redesign the economical, political and social system.
description: Il paper discute le biopolitiche di marginalizzazione fondate sulla proclamazione dello stato di eccezione e sull’uso della violenza come strumento di potere. Invita a considerare le favelas come luoghi paradigmatici per riflettere sulle pratiche di resistenza alle politiche di inclusione escludente gestite dalla governamentalità statale e dalla normazione criminale. Considera le favela come laboratori di nuove forme di soggettività che ripensano i fondamenti delle relazioni fra individui, Stato e Nazione e promuovono profili di cittadinanza basati sulla richiesta di partecipazione a ridisegnare il sistema economico, politico e sociale.

De nombreux chercheurs sont concernes par cet etat des faits et oeuvrent a retablir un certain equilibre ecologique. A travers cette modeste contribution nous avons essaye d'evaluer d'un point de vue economique la biodiversite du Parc National de l'Ichkeul qui se situe en Tunisie. Nous pensons effectivement, que la reconnaissance de l'importance biologique ne serait que mieux consideree etant donnee la valeur economique qui lui est attribuee. Afin de proceder a notre evaluation, nous avons eu recours: (1) A deux modeles econometriques specifiques, l'un lie a la peche l'autre a l'ecotourisme; (2) A un modele theorique d'evaluation economique des plantes medicinales; (3) A une analyse couts/benefices des amenagements hydrauliques. Par ailleurs, le lecteur trouvera tout le long de sa lecture tous les elements historiques, geographiques, ecologiques ( ...) necessaires a sa bonne comprehension de notre travail. Nous insistons sur le fait que ce travail est une premiere dans le genre a l'echelle tunisienne d'ou la difficulte d'obtention de donnee pertinentes ou detaillees.

description: In urban areas, stormwater management ponds (SWPs) are built to mitigate polluted runoff. Although these ponds are increasing in numbers, their ecology is not well understood. Physical and chemical characteristics of 17 SWPs in the City of Ottawa were measured to determine the drivers of phytoplankton biomass (Chl. a) and primary production (PP). While total phosphorus was the best predictor of algal biomass in the ponds (as in lakes), the imperviousness of the catchment could also predict Chl. a. Planktonic PP in two ponds measured seasonally was more closely related to water residence time than to nutrient concentrations with rates approaching at times the theoretical maximum for aquatic systems. In one pond, whole ecosystem metabolism, estimated using diel changes in dissolved oxygen and δ18O-O2, suggested that these hypereutrophic systems were net sinks for carbon in the summer but likely sources to the atmosphere at other times of the year.

description: Encoding behaviorally relevant stimuli in a noisy background is critical for animals to survive in their natural environment. We identify core biophysical and synaptic mechanisms that permit the encoding of low frequency signals in pyramidal neurons of the weakly electric fish Apteronotus leptorhynchus, an animal that can accurately encode miniscule (0.1%) amplitude modulations of its self-generated electric field. We demonstrate that slow NMDA-R mediated EPSPs are able to summate over many interspike intervals of the primary electrosensory afferents (EAs), effectively eliminating the EA spike train serial correlations from the pyramidal cell input. This permits stimulus-evoked changes in EA spiking to be transmitted efficiently to downstream ELL pyramidal cells, where a dynamic balance of NMDA-R and GABA-A-R currents is critical for encoding low frequency signals. Interestingly, AMPA-R activity is depressed and plays a negligible role in the generation of action potentials; instead, cell intrinsic membrane noise implements voltage-dependent stochastic resonance to amplify weak sensory input and appears to drive a significant proportion of pyramidal cell spikes. Together, these mechanisms may be sufficient for the ELL to encode signals near the threshold of behavioral detection.
Jihadist media networks and virtual propaganda in the Russian cyberspace

description: This study marks the first attempt in Western scholarship to analyze the evolution of Al-Qaeda affiliated terrorist groups’ and the Islamic State’s online branding in the Russian Federation, trying to explain how radicals’ sporadic activities have been transformed into recognizable brands and how to counter terrorist branding. It relies on products that are directly produced and presented on the Russian part of the Internet in 2013 - 2017. The study scrutinizes the set of issues related to the presence of radical groups in cyberspace through the prism of brand identity theory, framing Al-Qaeda and the Islamic State as corporations that have created and advanced their global brands in order to disseminate their products across the world. Both groups embraced a set of sub-brands, however, the Al-Qaeda network produced a larger number of local brands with well-articulated identities compared to the Islamic State network. The study reveals that while the ISIS network focused on the promotion of its global brand through domestic outlets, the Al-Qaeda network advanced local sub-brands, overshadowing its master brand. The research discovered that these organizations practiced a different approach to their networking, Internet presence, and production strategy. Further research is needed on online fundraising campaigns conducted by radicals as well as the limits of censorship software.

description: The purpose of the paper is to confirm the existence of a customer service model within the provision of on-line marketing of education. Previous studies relating to customer service models were adapted to determine the efficacy of the constructs in the education context. The data set comprised 328 responses from a questionnaire survey of undergraduate students enrolled in marketing subjects. The major finding is that five factors were found relating to the use of WebCT as an on-line education tool. These factors in order of weightings are ease of use, level of enjoyment and positive self-image, time saving elements, usefulness and its helpfulness as an administration tool. The study clearly signposts areas of development of WebCT as a learning tool for future use in marketing education.

description: In this paper, we analyse the impact of the HHL quantum algorithm on stream ciphers in a black-box setting. We assume a black-box access to an oracle MS defining the output of the stream cipher. For a state k encapsulating the key material, the value MS ⋅ k is the keystream (k'1, k'2, ..., k'N) generated by some stream cipher S. We translate this scenario into the quantum setting and describe how the HHL algorithm could be used to attack this construction. Further, we give simple and verifiable criteria under which a black-box attack on stream ciphers with the HHL algorithm is not efficiently feasible. Usually, these criteria follow from already known design principles for symmetric ciphers and should apply to the ciphers used today. We complement the criteria with a simple test, which confirms the resistance of said cipher. Moreover, we use our technique to test the currently used stream ciphers: Trivium, HC-128, and Salsa20.

description: Quantum mechanical tunnelling occurs when a molecule transforms between two states separated by a finite energy barrier that cannot be overcome thermally. To date, it has been observed for elements up to oxygen. Efforts to go one element further are hindered by the strong bonds formed by fluorine with other elements, which suppress tunnelling. In this work, laser ablation is used to create fluorine-only species and trap weakly-bound polyfluorides in a neon matrix at cryogenic temperatures. Spectroscopic investigations reveal a temperature-dependent doublet-splitting, providing experimental evidence for heavy-atom quantum mechanical tunnelling. Theoretical modelling attributes the signal to tunnelling of the central fluorine atom in a quasi-linear [F2 ⋯  F ⋯  F2]− complex through a rotational barrier caused by steric hindrance and electronic effects in the neon matrix. The present study offers new insights into chemical interactions in polyfluorides and, more generally, of quantum phenomena in confined environments.
