description: In recent years, the gap between theory and practice in quantum key distribution (QKD) has been significantly narrowed, particularly for QKD systems with arbitrarily awed optical receivers. The status for QKD systems with imperfect light sources is however less satisfactory, in the sense that the resulting secure key rates are often overly-dependent on the quality of state preparation. This is especially the case when the channel loss is high. Very recently, to overcome this limitation, Tamaki et al proposed a QKD protocol based on the so-called rejected data analysis, and showed that its security|in the limit of infinitely long keys|is almost independent of any encoding flaw in the qubit space, being this protocol compatible with the decoy state method. Here, as a step towards practical QKD, we show that a similar conclusion is reached in the finite-key regime, even when the intensity of the light source is unstable. More concretely, we derive security bounds for a wide class of realistic light sources and show that the bounds are also efficient in the presence of high channel loss. Our results strongly suggest the feasibility of long distance provably-secure communication with imperfect light sources.

description: Background/aims Borderline personality disorder (BPD) is a severe mental disorder characterized by an unstable sense of self, intense and rapidly changing affect, as well as impulsive and self-destructive behaviors. Interpersonal relationships of individuals with BPD are characterized by marked instability, a lack of dependability, and quick changes between love and hate. For children of individuals with BPD, this can lead to permanent stress and attachment insecurity and an increased risk of adverse physical and mental health development. To reduce dysfunctional parenting and improve positive parenting, and in turn, to promote healthy child development, a group intervention for mothers with BPD was developed. This study aims to evaluate this first disorder-specific parenting intervention for BPD in a randomized controlled trial. Method In a parallel-group, two-arm, randomized controlled trial, an initial N = 178 mothers diagnosed with BPD and their children aged 6 months to 6 years are assigned to either the parenting intervention or a waiting control group. If taking place, participants of both groups continue their regular treatment for BPD diagnosis (e.g., individual therapy, medication). The primary outcomes are changes in parenting from baseline (day 0) to post intervention (week 12) and follow-up (6 months after group intervention; month 9). The waiting control group can attend the group intervention at the end of all assessments. Participants allocated to the intervention group are expected to show improvement in their parenting and a reduction in child abuse potential. Maternal emotion regulation and mental distress are analyzed as secondary outcomes. Discussion Mothers with BPD may need tailored help when reporting difficulties raising their children. The first disorder-specific parenting intervention has been developed to close this gap. ProChild is part of a large government-supported consortium, which aims to investigate different aspects of abuse and maltreatment in childhood and adolescence.

description: Additive manufacturing (AM), also known as 3D printing, attracts increasing interests from industry due to its simplicity and low cost. However, 3D printing-induced interfaces which could influence the potential of AM in industrial applications which are required to exhibit high mechanical performance and durability in harsh environment. This thesis investigates the relationship of the manufacturing process-induced interfaces and the properties of printed (short fibre reinforced) polyamide. Partially bonded interfaces induced by the manufacturing process were found between the layers of printed polyamide and short fibre reinforced polyamide (SFRN). The printed SFRN exhibited inferior interfaces compared to polyamide and the resulting mechanical performance was more significantly influenced. The tensile modulus of 3 mm SFRN was decreased as a function of interface density (number of interfaces per unit sample thickness) from 4.57 GPa to 3.88 GPa. This thesis also investigates the moisture absorption of printed polyamide and SFRN. The measured diffusion coefficients of printed SFRN increased as a function of the number of interfaces which increased the moisture absorption kinetics. The influence of moisture absorption on the mechanical performance of printed samples was evaluated. Reduced shear properties indicated the bonding between layers and within layers degraded with absorbed moisture content. The tensile properties of printed samples exposed to moisture decreased more significantly compared to injection moulded samples due to the degraded interfacial property. Moreover, moisture absorption was found to have an irreversible impact on the partially bonded interfaces between adjacent filaments. The resulting tensile and shearing properties of printed samples were not fully recovered after the drying process due to the aggravated interfaces.

Model-based resource management for fine-grained services

Publisher: name: Imperial College London

description: The emergence of DevOps has changed the way modern distributed software systems are developed. Architectures decomposed in fine-grained services, such as microservices or function-as-a-service (FaaS), are now widespread across many organizations. From a resource management perspective, although the systems built with such architectures have many benefits, there are still research challenges that need further attention. In this study, we have focused on three such challenges, each concerning a specific system resource: compute, memory, or storage. Firstly, we focus on scaling the capacity of microservices at runtime. Here, the challenge is to design an autoscaler that can decide between vertical and horizontal scaling options to distribute the CPU capacity. Secondly, we focus on estimating the required capacity of an on-premises FaaS platform such that the service level agreements (SLAs) for function response times are satisfied. The challenge here is to address the cold start dilemma, i.e., that a cold start delays a function response but reduces the memory consumption. Thus, we must find a limit of cold starts such that the memory-consumption remains in-check while satisfying the SLAs. Finally, we focus on the storage management for distributed tracing targeted at microservices. The volume of such traces generated in a data center can be in the scale of tens of terabytes per day, but only a small fraction of these traces is useful for troubleshooting. The objective then is to sample only the useful traces. The key to addressing all these challenges is first, modeling the dynamics concerning the resources and subsequently, leveraging the model in a resource controller. To address the first challenge, we have developed an autoscaler ATOM that leverages layered queueing network (LQN) models to take its scaling decisions. Our experiment, with a real-life application, shows that ATOM produces 30-37% better results than the baseline autoscalers. For the second challenge, we have developed COCOA, a cold start aware capacity planner. COCOA utilizes M/M/k setup and LQN models to assess the cold start scenario and estimate the required capacity. We show with simulation that COCOA can reduce over-provisioning by over 70% compared to the availability aware approaches. Finally, addressing the third challenge, we propose SampleHST, a trace sampler that works under a storage budget constraint. SampleHST relies on either bag of words or graph-based models to represent a trace and groups similar traces using online clustering to perform sampling. We have evaluated the performance of SampleHST using data from both literature and production, which shows it produces 1.2x to 19x better results than the state-of-the-art.

description: We inspect a possible clustering structure of the corruption perception among 134 countries. Using the average linkage clustering, we uncover a well-defined hierarchy in the relationships among countries. Four main clusters are identified and they suggest that countries worldwide can be quite well separated according to their perception of corruption. Moreover, we find a strong connection between corruption levels and a stage of development inside the clusters. The ranking of countries according to their corruption perfectly copies the ranking according to the economic performance measured by the gross domestic product per capita of the member states. To the best of our knowledge, this study is the first one to present an application of hierarchical and clustering methods to the specific case of corruption.

description: Introduction
The question of what motivates people to participate in research is particularly salient in the HIV field. While participation in HIV research was driven by survival in the 1980’s and early 1990’s, access to novel therapies became the primary motivator with the advent of combination antiretroviral therapy (cART) in the late 1990s. In the HIV cure-related research context, the concept of altruism has remained insufficiently studied.

Methods
We conducted a scoping review to better contextualize and understand how altruism is or could be operationalized in HIV cure-related research. We drew from the fields of altruism in general, clinical research, cancer, and HIV clinical research–including the HIV prevention, treatment, and cure-related research fields.

Discussion
Altruism as a key motivating factor for participation in clinical research has often been intertwined with the desire for personal benefit. The cancer field informs us that reasons for participation usually are multi-faceted and complex. The HIV prevention field offers ways to organize altruism–either by the types of benefits achieved (e.g., societal versus personal), or the origin of the values that motivate research participation. The HIV treatment literature reveals the critical role of clinical interactions in fostering altruism. There remains a dearth of in-depth knowledge regarding reasons surrounding research participation and the types of altruism displayed in HIV cure-related clinical research.

Conclusion
Lessons learned from various research fields can guide questions which will inform the assessment of altruism in future HIV cure-related research.

Transcripts and transcription at an estrogen regulated enhancer of CCND1

Publisher: name: Imperial College London

description: Enhancer sequences have been well documented for over a decade, and whilst their function as gene expression regulators is widely appreciated, the mechanism by which they exert their control is not yet understood. Transcription of enhancer regions is linked to enhancer activity, but it is unclear if the enhancer RNA (eRNA) transcript is necessary for cis regulation or merely a by-product of transcription. Through RNA-Sequencing of estradiol (E2) treated MCF7 cells and the use of publicly available sequencing data, we have identified a region neighbouring the CCND1 gene locus which contains at least one enhancer whose bi-directional transcription is upregulated with E2 treatment in estrogen receptor (ER) positive breast cancer cell lines. This enhancer region is known to have cis-regulatory effects on the neighbouring CCND1 gene, whose amplification and overexpression is linked to a poorer prognosis and treatment resistance in ER positive breast cancers. To determine the role of the bi-directionally transcribed eRNAs arising from this enhancer region, we have identified their cellular location and used appropriate siRNA techniques to knockdown both transcripts. We show that siRNA knockdown of either eRNA does not affect regulation of the neighbouring CCND1 gene but premature termination of transcription of the antisense enhancer not only knocks-down the eRNA but also down regulates CCND1 and may have a more global effect on ER regulation. We discuss the challenges encountered in CRISPR/Cas9 mediated knock-in of a polyadenylation signal and compare the resultant effects of knockdown of these eRNA with the premature transcription termination of the enhancer from which they arise and discuss these findings in the context of alternative possible roles for eRNAs.

description: A growing body of research is beginning to elucidate reasons people living with HIV (PLWHIV) might prefer oral daily antiretroviral treatment (ART) compared with emerging long-acting ART (LA-ART) or HIV remission strategies under investigation. Our objective is to provide qualitative insights into the reasons why PLWHIV might prefer one of these HIV control therapies over others. From May to August 2018, we implemented a semistructured cross-sectional survey of PLWHIV in the United States to better understand patient preferences around various HIV treatment and remission options. Using free text, respondents were asked to explain why they preferred one HIV control option over the other two. We analyzed responses to the open-ended survey questions on reasons for preferring oral daily ART versus LA-ART versus HIV remission strategies using conventional content analysis. The results showed that PLWHIV preferred oral daily ART because of its familiarity and known safety and efficacy profile, whereas those who preferred LA-ART would value the convenience it offers. Finally, HIV remission strategies would be preferred to avoid taking ART altogether. The qualitative results provide insights into reasons why PLWHIV in the United States might prefer oral daily ART versus novel therapies. More importantly, they provide information to better align HIV virological control strategies with end-user perspectives. To make informed choices around evolving HIV therapeutics, PLWHIV and HIV care providers would benefit from decision tools to better assess options and trade-offs. More research is needed on how best to effectively support PLWHIV and HIV care providers in shared decision-making.

description: Young open clusters located in the outer Galaxy provide us with an opportunity to study star formation activity in a different environment from the solar neighborhood. We present a UBVI and H alpha photometric study of the young open clusters NGC 1624 and NGC 1931 that are situated toward the Galactic anticenter. Various photometric diagrams are used to select the members of the clusters and to determine the fundamental parameters. NGC 1624 and NGC 1931 are, on average, reddened by = 0.92 +/- 0.05 and 0.74 +/- 0.17 mag, respectively. The properties of the reddening toward NGC 1931 indicate an abnormal reddening law (Rv,cl = 5.2 +/- 0.3). Using the zero-age main sequence fitting method we confirm that NGC 1624 is 6.0 +/- 0.6 kpc away from the Sun, whereas NGC 1931 is at a distance of 2.3 +/- 0.2 kpc. The results from isochrone fitting in the Hertzsprung-Russell diagram indicate the ages of NGC 1624 and NGC 1931 to be less than 4 Myr and 1.5 - 2.0 Myr, respectively. We derived the initial mass function (IMF) of the clusters. The slope of the IMF (Gamma_NGC 1624 = -2.0 +/- 0.2 and Gamma_NGC 1931 = -2.0 +/- 0.1) appears to be steeper than that of the Salpeter/Kroupa IMF. We discuss the implication of the derived IMF based on simple Monte-Carlo simulations and conclude that the property of star formation in the clusters seems not to be far different from that in the solar neighborhood.

description: End-of-life (EOL) HIV cure-related research provides a novel approach to studying HIV reservoirs. The Last Gift is a rapid autopsy research study at the University of California San Diego that enrolls terminally ill people living with HIV (PLWHIV) with a desire to contribute to HIV cure-related research. We conducted in-depth baseline and follow-up interviews with Last Gift study participants. We analyzed interview data applying conventional content analysis. Since summer 2017, 13 participants have been enrolled (n = 11 males and 2 females; aged 45-89 years) and 8 participants interviewed. Terminal illnesses included cancers, heart diseases, and neurodegenerative illnesses. Our analysis revealed five key themes: (1) The Last Gift study has tremendous meaning for participants at the end of their life. (2) HIV-specific altruism was a primary motivator to join the Last Gift study, nested within the context of community, scientific advancement, and moral obligation. (3) Participants did not expect physical benefits yet they perceived emotional/psychological, financial, and societal/scientific benefits. (4) There were minimal participant-perceived risks and concerns. (5) Last Gift participants expressed immense gratitude toward study staff. The Last Gift study provides a framework for ethical HIV cure-related research at EOL and highlighted participants' perspectives, motivations, and experiences. Knowing how PLWHIV understand and experience such studies will remain critical to designing ethical, fully informed HIV cure research protocols that are acceptable to PLWHIV.

description: We derive the effective low energy Hamiltonian for the tight-binding model with the hopping integral slowly varying along the chain. The effective Hamiltonian contains the kinetic energy with position dependent mass, which is inverse to the hopping integral, and effective potential energy. Changing of ordering in the kinetic energy leads to change of the effective potential energy and leaves the Hamiltonian the same one. Therefore, we can choose arbitrary von Roos ordering parameters in the kinetic energy without changing the Hamiltonian. Moreover, we propose a more general form for the kinetic energy than that of von Roos, which nevertheless together with the effective potential energy represent the same Hamiltonian.

description: Despite possessing a local spin $2$ moment on the iron site and a Curie-Weiss temperature of $45K$, the A site spinel FeSc$_2$S$_4$ does not magnetically order down to 50mK. Previous theoretical work by Chen and Balents advanced an explanation for this observation in the form of the "$J_2$-$λ$" model which places FeSc$_2$S$_4$ close to a quantum critical point on the disordered side of a quantum phase transition between a Néel ordered phase and a "Spin-Orbital Liquid" in which spins and orbitals are entangled, quenching the magnetization. We present new theoretical studies of the optical properties of the $J_2$-$λ$ model, including a computation of the dispersion relation for the quasiparticle excitations and the form of the collective response to electric field. We argue that the latter directly probes a low energy excitation continuum characteristic of quantum criticality, and that our results reinforce the consistency of this model with experiment.

description: A growing number of people living with HIV/AIDS are participating in HIV cure-related research at the end of life (EOL). Due to the novelty of EOL HIV cure-related research, there is a need to understand how their next-of-kin (NOK) perceive such research. We conducted in-depth interviews with NOK of the Last Gift study participants at the University of California, San Diego. The Last Gift study occurs in the context of the EOL and involves a full body donation. NOK completed two interviews: (1) shortly after the participants' enrollment in the study and (2) following death. We applied thematic analysis to analyze qualitative data. NOK included seven individuals (five males and two females), including two spouses, one ex-partner, one sister, a grandmother/grandfather, and a close friend. Thematic analysis revealed five key themes: (1) NOK viewed the Last Gift program in a positive light and had an accurate overall understanding of the study; (2) NOK identified factors that motivated participants to donate their body to science; (3) NOK identified benefits of the Last Gift program for both the donors and themselves; (4) NOK did not perceive any physical risks or decisional regrets of study but wanted to minimize psychosocial impacts and ensure the dignity of participants at all times; and (5) NOK noted elements that remained essential to the successful implementation of EOL HIV cure-related research, such as early involvement and clear communication. Our study uniquely contributes to increased understanding and knowledge of what is important from the point of view of supportive NOK to ensure successful implementation of EOL HIV cure-related research. More research will be needed to understand perspectives of less supportive NOK.

description: Nach wie vor nimmt das Medium Radio eine wichtige Rolle im Medienkonsum der Österreicher*innen ein. Um Radiosender bestmöglich zu positionieren und die Zielgruppen zu erreichen, bedarf es als Radioredakteur*in allerdings nicht mehr nur der Arbeit mit Audio, sondern jener mit verschiedenen Medien und auf unterschiedlichen Plattformen. Es werden Inhalte für Radio, Social Media sowie Online produziert. Dabei müssen Redakteur*innen neue Kompetenzen mitbringen. Diese Form des neuen Arbeitens nennt sich crossmediales Arbeiten. Sie steht im Fokus dieser Masterarbeit, welche sich den drei bundesweiten ORF- Radiosendern Ö1, Ö3 und FM4 widmet. Fünfzehn Journalist*innen dieser drei Sender wurden mittels Leitfadeninterview befragt. Dabei war das Ziel, Crossmedia ganzheitlich zu erforschen. Einerseits wurde das theoretische Verständnis von Crossmedia besprochen. Andererseits sollten Faktoren, die crossmediales Arbeiten sowohl positiv als auch negativ beeinflussen, ermittelt werden. Die Ergebnisse der durchgeführten qualitativen Inhaltsanalyse zeigen, dass das Verständnis von Crossmedia noch wenig verbreitet scheint. Drei verschiedene Herangehensweisen, um Crossmedia zu beschreiben, wurden festgestellt. Crossmedia in der praktischen Umsetzung war den Interviewten hingegen eher vertraut. Sieben Faktoren, welche für das crossmediale Arbeiten förderlich oder hinderlich sein können, sind das Ergebnis dieser Forschungsarbeit. Diese sind der Mikro-, Meso- und Makro- Ebene zuzuordnen.
description: Radio plays an important role in the media consumption among Austrians. In order to position radio stations in the best possible way and to reach the target groups, radio journalists no longer only need to work with audio, but also with different forms of media and on different platforms. They have to produce content for the radio, social media and online. Therefore, journalists must be able to bring new skills with them. This kind of work is called cross- media-work, which is the main topic of this master's thesis. The thesis concerns the three nationwide ORF radio stations, Ö1, Ö3 and FM4. The author of this thesis interviewed fifteen journalists from these three radio stations using a guided interview. The aim was to explore cross-media in a very holistic way. Firstly, the author of this thesis discussed the theoretical understanding of cross-media. Also, the writer looked at factors that influence cross-media-work both positively and negatively. The results of the qualitative content analysis show that the understanding of cross-media is still not very widespread. This research project shows three different approaches to describe cross-media in a theoretical way. The interviewees were more familiar with cross-media in the practical sense. Seven factors demonstrate how cross-media can be promoted or prevented. These factors are located on the micro, meso and macro level.

description: В работе приведены результаты исследования термоэлектрического эффекта истинного раствора, коллоидного и их смеси. Проведены серийные измерения коэффициента термоэлектрической ЭДС растворов в зависимости от их разбавления. На основании полученных результатов можно сделать вывод, что коллоидные частицы, которые имеют высокие значения теплоты переноса и низкие значения подвижности, начинают вносить заметный вклда в итоговую величину термоЭДС смеси золя и истинного раствора, только при низких концентрациях ионного электролита. С другой стороны, в области высоких концентраций электролита термоЭДС смеси определяется ионами, имеющими высокие значения подвижности.

description: We are concerned with finding explicit generators of the Brauer group of diagonal cubic surfaces in terms of norm residue symbols, which was originally studied by Manin. We introduce the notion of uniform generators and find that the Brauer group of some classes of diagonal cubic surfaces have uniform generators. However, we also prove that the Brauer group of general diagonal cubic surfaces do not have such ones. This reveals that a result of Manin for certain diagonal cubic surfaces cannot be generalized in some sense.

title: Construction on the Moon: The potential of microwave processing of lunar soil

description: The future of human expansion to our nearest neighbour, the Moon and beyond, relies on the utilisation of the available in situ resources on the respective planetary bodies. These resources can be suitable for construction, fuel production, mineral extraction, life support, and consumables required for a sustainable human presence off-Earth. This research describes the use of microwave energy for investigating the potential of lunar construction using lunar regolith. Microwaves of frequency 2.45 GHz and 1.0 kW power are used to heat the lunar soil simulants (LSS) JSC-1A and NU-LHT-3M to predict the microwave heating behaviour of lunar Mare and Highland region samples. The dielectric properties of material define whether it will reflect, absorb, or be transparent to the incident microwave. The temperature-dependent dielectric properties of the LSS are determined using the cavity perturbation technique; both materials were found to be absorbers. Using this data, a theoretical analysis is carried out to predict the microwave heating behaviour of LSS with temperature. A computational analysis using Multiphysics software is then presented to quantify the influence of heat losses on the microwave heating of LSS in a domestic microwave oven used for experiments. These results form the basis of experimental tests in a domestic microwave oven. The combined results of the theoretical, simulation and experimental activities are used to design a bespoke microwave (BM) of industrial standards with better features to handle the heating and melting of LSS; these include the ability to record sample surface temperatures and to alter the atmospheric pressure and composition. Experiments with the BM demonstrate that Mare region samples (similar to JSC-1A) will exhibit better microwave heating susceptibility than the Highland region samples (similar to NU-LHT-3M) on the Moon. Further tests investigated the importance of water content in the lunar soil. It revealed that this water acts likely as a susceptor for highland region samples, which are low absorbers of microwave at 2.45 GHz, 1.0 kW themselves.

description: Статья посвящена исследованию терминов «дискурс» и «дискурсивное поле». Актуальность работы заключается в том, что дискурс всегда необходим для работы с текстами, что играет одну из главных ролей в работе любого лингвиста. Методология исследования опирается на общенаучные подходы. Новизной исследования является рассмотрение и изучение аналитического подхода к исследованию устной и письменной речи, который необходим для анализа текстов. Основными выводами проведенного исследования являются теоретическая значимость и практическая ценность того, что дискурс многогранен, а дискурсивные поля порождают более узкие поля по содержанию, что может напомнить нам о бесконечности. Таким образом, изучив данные термины, мы пришли к выводу, что без дискурса нет возможности глубже изучить и понять текст, культуру и ценности культуры.

description: Two HIV virologic control advances are in various stages of development, including long-acting antiretroviral therapy (ART) formulations and strategies aimed at sustained ART-free HIV control. Perceptions of risks and benefits toward HIV virologic control strategies may be different based on an individual's age due to differing experiences of the impacts of the domestic HIV epidemic, altruistic attitudes toward research participation, and general levels of engagement in health care. We examined preferences of HIV virologic control strategies by age groups. In 2018, we conducted a nationwide, online cross-sectional survey to examine differences in HIV virologic control strategies among a sample of people living with HIV who were <50 and >= 50 years of age. From a total of 281 participants, 3 findings were noteworthy: (1) Participants <50 years of age were more likely to be demotivated by perceived social risks (e.g., stigma, discrimination, HIV disclosure, and fear of transmitting HIV during a treatment interruption), compared with those >= 50 years; (2) participants >= 50 years of age were more motivated by altruistic notions compared with those <50 years; and (3) we noted greater desirability of longer long-acting ART and new HIV cure-related strategies among participants <50 years versus those >= 50 years. Our analysis provides a deeper understanding of differences in perceptions among various age groups regarding desirable future ART characteristics, and motivations and barriers to participating in HIV cure-related strategies. Our findings can help inform community engagement and education, and assist researchers in tailoring study design and recruitment efforts to major age groups.
Willingness to Risk Death Endpoint in HIV Cure-Related Research with Otherwise Healthy Volunteers is Misleading

description: This viewpoint article critiques two recent articles examining 'willingness to risk death' to advance HIV cure-related research. The 'willingness to risk death' endpoint sends the wrong signal to the HIV cure-related research community about ongoing research in otherwise healthy volunteers living with HIV. Socio-behavioural scientists have examined the acceptability of a 99% risk of death scenario, which is unrealistic and would not be acceptable by current regulatory and ethical standards. We believe that the field needs robust and relevant socio-behavioural research reflecting ongoing biomedical HIV cure-related trials. These studies will need to withstand regulatory and ethical scrutiny if cure or remission regimens are to proceed to the licensing stage. The HIV cure-related research community must continue to protect the public trust in the HIV cure-related research field and sustain societal value generated by such research. We call for the utmost prudence in designing biomedical HIV cure trials as well as in setting up socio-behavioural research experiments related to these complex trials.

description: Recent studies from social, biological, and engineering network systems have drawn attention to the dynamics over signed networks, where each link is associated with a positive/negative sign indicating trustful/mistrustful, activator/inhibitor, or secure/malicious interactions. We study asymptotic dynamical patterns that emerge among a set of nodes that interact in a dynamically evolving signed random network. Node interactions take place at random on a sequence of deterministic signed graphs. Each node receives positive or negative recommendations from its neighbors depending on the sign of the interaction arcs, and updates its state accordingly. Recommendations along a positive arc follow the standard consensus update. As in the work by Altafini, negative recommendations use an update where the sign of the neighbor state is flipped. Nodes may weight positive and negative recommendations differently, and random processes are introduced to model the time-varying attention that nodes pay to these recommendations. Conditions for almost sure convergence and divergence of the node states are established. We show that under this so-called state-flipping model, all links contribute to a consensus of the absolute values of the nodes, even under switching sign patterns and dynamically changing environment. A no-survivor property is established, indicating that every node state diverges almost surely if the maximum network state diverges.
