description: Although WO3 appears to be one of the extensively studied photocatalyst, the low response of pure WO3 in aqueous solution under visible light limits its application remarkably. In this work, the enhancement of the efficiency of WO3 for the visible light driven photocatalytic oxidation of arsenite was explored using Cu2+ ion and CuO as a co-catalyst. While the addition of Cu2+ was found effective for the suppression of dissolution of WO3, the efficiency of CuO appeared to be slightly lower. Significant improvement of the efficiency for the photocatalytic oxidation of As(III) with WO3 was noted when Cu2+ ion and CuO were added. The optimized conditions were WO3 in the presence of 10 mg L-1 Cu2+ ion and 1 wt% CuO coupled with WO3, respectively. The As(III) concentration of 10 mg L−1 could be lowered to less than 0.1 mg L−1 by the photocatalytic treatment. Acidic pH favours the oxidation arsenite in the presence of Cu2+ whereas basic pH is suitable with CuO. Characterization techniques such as TEM, XPS, XRD and UV-DRS were used to characterize photocatalysts. The reactive species scavenger test revealed that the photo–induced holes (h+) play a key role in the photocatalytic oxidation process while the effect of •OH is negligible. It was found that As(III) oxidation rate was remarkably suppressed in nitrogen atmosphere. A mechanism for the enhanced photocatalytic oxidation has been proposed based on the results of reactive species scavenger test. This research may contribute to the large–scale As(III) oxidation treatment in the ground water.

description: We consider quantum field theories on supermanifolds using integral forms. The latter are used to define a geometric theory of integration and they are essential for a consistent action principle. The construction relies on Picture Changing Operators, analogous to the one introduced in String Theory. As an application, we construct a geometric action principle for N=1 D=3 super-Chern-Simons theory.

description: The site-diluted compound (Yb$_{1-x}$Lu$_x$)$_4$As$_3$ is a scarce realization of the linear Heisenberg antiferromagnet partitioned into finite-size segments and is an ideal model compound for studying field-dependent effects of quenched disorder in the one-dimensional antiferromagnets. It differentiates from the systems studied so far in two aspects - the type of randomness and the nature of the energy gap in the pure sample. We have measured the specific heat of single-crystal (Yb$_{1-x}$Lu$_x$)$_4$As$_3$ in magnetic fields up to 19.5 T. The contribution $C_{\perp}$ arising from the magnetic subsystem in an applied magnetic field perpendicular to the chains is determined. Compared to pure Yb$_4$As$_3$, for which $C_{\perp}$ indicates a gap opening, for diluted systems a non-exponential decay is found at low temperatures which is consistent with the thermodynamic scaling of the specific heat established for a Bose-glass phase.

description: Shocks act to convert incoming supersonic flows to heat, and in collisionless plasmas the shock layer forms on kinetic plasma scales through collective electromagnetic effects. These collisionless shocks have been observed in many space and astrophysical systems [Smith 1975, Smith 1980, Burlaga 2008, Sulaiman 2015], and are believed to accelerate particles, including cosmic rays, to extremely high energies [Kazanas 1986, Loeb 2000, Bamba 2003, Masters 2013, Ackermann 2013]. Of particular importance are the class of high-Mach number, supercritical shocks [Balogh 2013] ($M_A\gtrsim4$), which must reflect significant numbers of particles back into the upstream to accommodate entropy production, and in doing so seed proposed particle acceleration mechanisms [Blandford 1978, McClements 2001, Caprioli 2014, Matsumoto 2015]. Here we present the first laboratory generation of high-Mach number magnetized collisionless shocks created through the interaction of an expanding laser-driven plasma with a magnetized ambient plasma. Time-resolved, two-dimensional imaging of plasma density and magnetic fields shows the formation and evolution of a supercritical shock propagating at magnetosonic Mach number $M_{ms}\approx12$. Particle-in-cell simulations constrained by experimental data show in detail the shock formation, separate reflection dynamics of C$^{+6}$ and H$^{+1}$ ions in the multi-species ambient plasma, and density and magnetic field compressions and overshoots in the shock layer. The development of this experimental platform complements present remote sensing and spacecraft observations, and opens the way for controlled laboratory investigations of high-Mach number collisionless shocks, including the mechanisms and efficiency of particle acceleration.

description: In this work we analyze the distribution of quantum entanglement over communication channels in the millimeter-wave regime. The motivation for such a study is the possibility for next-generation wireless networks (beyond 5G) to accommodate such a distribution directly - without the need to integrate additional optical communication hardware into the transceivers. Future wireless communication systems are bound to require some level of quantum communications capability. We find that direct quantum-entanglement distribution in the millimeter-wave regime is indeed possible, but that its implementation will be very demanding from both a system-design perspective and a channel-requirement perspective.

A longer working life for Australian women of the baby boom generation?: Women's voices and the social policy implications of an ageing female workforce
Creators: name: Merkes, Monika
Publisher: name: La Trobe
Year: 2023

description: With an increasing proportion of older people in the Australian population and increasing health and longevity, paid work after the age of 65 years may become an option or a necessity in the future. The focus of this research is on Australian women of the baby boom generation, their working futures, and the work-retirement decision. This is explored both from the viewpoint of women and from a social policy perspective. The research draws on Considine's model of public policy, futures studies, and Beck's concept of risk society. The research comprises three studies. Using focus group research, Study 1 explored the views of Australian women of the baby boom generation on work after the age of 65 years. Study 2 aimed to explore current thinking on the research topic in Australia and overseas. Computer-mediated communication involving an Internet website and four scenarios for the year 2020 were used for this study. Study 3 consists of the analysis of quantitative data from the Healthy Retirement Project, focusing on attitudes towards retirement, retirement plans, and the preferred and expected age of retirement. The importance of choice and a work - life balance emerged throughout the research. Women in high-status occupations were found to be more likely to be open to the option of continuing paid work beyond age 65 than women in low-status jobs. However, the women were equally likely to embrace future volunteering.The research findings suggest that policies for an ageing female workforce should be based on the values of inclusiveness, fairness, self-determination, and social justice, and address issues of workplace flexibility, equality in the workplace, recognition for unpaid community and caring work, opportunities for life-long learning, complexity and inequities of the superannuation system, and planning for retirement. Further, providing a guaranteed minimum income for all Australians should be explored as a viable alternative to the current social security system.

description: In laser micromachining, the ablation threshold (minimum fluence required to cause ablation) is a key performance parameter and overall indicator of the efficiency of material removal. For pulsed laser micromachining, this important observable depends upon material properties, pulse properties and the number of pulses applied in a complex manner that is not yet well understood. The incubation effect is one example. It manifests as a change in the ablation threshold as a function of number of laser pulses applied and is driven by photoinduced defect accumulation in the material. Here, we study femtosecond (800 nm, 110 fs, 0.1-1 mJ/pulse) micromachining of a material with well-defined initial defect concentrations: doped Si across a range of dopant types and concentrations. The single-pulse ablation threshold (Fth,1) was observed to decrease with increasing dopant concentration, from a maximum of 0.70 J/cm2 (+/-0.02) for undoped Si to 0.51 J/cm2 (+/-0.01) for highly N-type doped Si. The effect was greater for N-type doped Si than for P-type, consistent with the higher carrier mobility of electrons compared to holes. In contrast, the infinite-pulse ablation threshold (Fth,inf) was the same for all doping levels and types. We attribute this asymptotic behaviour to a maximum defect concentration that is independent of the initial defect concentration and type. These results lend insight into the mechanism of multipulse, femtosecond laser ablation.

description: In order to achieve cure for HIV-1 infection in patients undergoing suppressive antiretroviral therapy, eradication of all latently infected reservoirs of the virus is required. The focus of HIV cure is predominantly centred on the elimination of latently infected memory T cells, while information on possible elimination of infected macrophages is lacking. Macrophages support continuous virus replication without succumbing to cytopathic effects of HIV-1. Recently, our laboratory has shown a protective role for cellular inhibitor of apoptosis proteins (IAPs) 1/2 in macrophages against Vpr-induced apoptosis. Depletion of cIAP1/2 by Smac mimetics (SM) reverse the IAP-mediated protection and sensitize macrophages to Vpr-induced cell death. My research aims to understand the role IAPs play in apoptotic resistance of HIV-infected macrophages. I hypothesized that ablation of cIAP1/2 by SM may induce apoptosis in HIV-infected macrophages. My results show that SM does not induce cell death in uninfected or healthy macrophages, but induces cell death in chronically infected U1 cells, in vitro infected monocyte-derived macrophages, and ex vivo derived HIV-infected macrophages from HIV-infected individuals. SM induce cell death of infected myeloid cells through apoptosis and not through necroptosis. Moreover, SM-induced apoptosis is independent of TNFα and other endogenously secreted cytokines. In vitro infection of monocyte-derived macrophages leads to the downregulation of RIPK1, RIPK3, and TRAF-1. Interestingly, necrostatin-1-mediated RIPK1- inhibition does not affect viability of healthy macrophages, but in combination with IAP degradation by SM leads to significant induction of apoptosis. This suggests a key role for RIPK1 in SM-induced apoptosis of HIV-infected macrophages. Altogether, the results from this project suggest that modulation of the IAP-associated signalling pathways by SM may be a potential strategy for selective killing of HIV-infected macrophages.

title: A plea for taking all available clinical information into account when assessing the predictive value of omics data

description: Background Omics data can be very informative in survival analysis and may improve the prognostic ability of classical models based on clinical risk factors for various diseases, for example breast cancer. Recent research has focused on integrating omics and clinical data, yet has often ignored the need for appropriate model building for clinical variables. Medical literature on classical prognostic scores, as well as biostatistical literature on appropriate model selection strategies for low dimensional (clinical) data, are often ignored in the context of omics research. The goal of this paper is to fill this methodological gap by investigating the added predictive value of gene expression data for models using varying amounts of clinical information. Methods We analyze two data sets from the field of survival prognosis of breast cancer patients. First, we construct several proportional hazards prediction models using varying amounts of clinical information based on established medical knowledge. These models are then used as a starting point (i.e. included as a clinical offset) for identifying informative gene expression variables using resampling procedures and penalized regression approaches (model based boosting and the LASSO). In order to assess the added predictive value of the gene signatures, measures of prediction accuracy and separation are examined on a validation data set for the clinical models and the models that combine the two sources of information. Results For one data set, we do not find any substantial added predictive value of the omics data when compared to clinical models. On the second data set, we identify a noticeable added predictive value, however only for scenarios where little or no clinical information is included in the modeling process. We find that including more clinical information can lead to a smaller number of selected omics predictors. Conclusions New research using omics data should include all available established medical knowledge in order to allow an adequate evaluation of the added predictive value of omics data. Including all relevant clinical information in the analysis might also lead to more parsimonious models. The developed procedure to assess the predictive value of the omics data can be readily applied to other scenarios.

description: Developing countries can produce sugar at much lower cost than it can be produced in the EU, yet reform of the EU sugar policy will result in both winners and losers among them. Reform will benefit competitive sugar exporters currently excluded from the EU market. It will adversely affect those developing countries that currently benefit from preferential import access to the EU's high-priced sugar market, while diminishing the benefits received by those least-developed countries to which duty-free and quota-free access has been promised after July 2009. This article identifies the countries likely to lose and the extent of their potential losses. It examines alternative proposals that have been put forward to assist these countries to adjust to the adverse effects of EU sugar policy reform and contributes to the debate by putting forward a further proposal.

description: We report the discovery of a new Kepler first-overtone RR Lyrae pulsator, KIC 2831097. The pulsation shows large, 0.1 d amplitude, systematic phase variations that can be interpreted as light travel-time effect caused by orbital motion in a binary system, superimposed on a linear pulsation-period decrease. The assumed eccentric (e=0.47) orbit with the period of approximately 2 yr is the shortest among the non-eclipsing RR Lyrae binary candidates. The binary model gives a lowest estimate for the mass of the companion of 8.4 M_Sun, that places it among black hole candidates. Beside the first-overtone pulsation, numerous additional non-radial pulsation frequencies were also identified. We detected an ~47-d Blazhko-like irregular light-curve modulation.

Relating women: lesbian experience of friendship
Creators: name: Lienert, Tania
Publisher: name: La Trobe
Year: 2023

description: Abstract: Friends are of crucial importance to lesbians' lives, their significance heightened due to lack of acceptance from blood family, work colleagues and society. Despite a proliferation of literature on lesbians' love relationships, lesbians' friendships remain understudied. In the light of theorising about widespread shifts in intimacy patterns in modern industrial societies, this thesis examines the role of friendship for contemporary lesbians. It takes an interdisciplinary approach, using lesbian feminist, feminist psychological and mainstream sociological theories to interpret lesbians' negotiations of their friendships and preoccupations with their own continually developing sense of self.The study finds that firstly, the most significant issue in negotiating friendships is deciding on a lesbian identity despite socialisation to 'compulsory heterosexuality'. Friends are expected to be accepting and supportive or they are lost. Discrimination, the fact that the lover is the 'best friend', struggles with difference in lesbian communities, time constraints and a more general shift to individualism mean that community and family contacts are replaced by small, supportive and affirming friendship networks. These meet needs and within them lesbians negotiate a sense of self, but for the most part with no template of political consciousness. Secondly, while friendships are important, they are also difficult. The fluidity of the friendship relationship, blurred boundaries between friends and lovers, and women's moral 'imperative to care' all provide barriers to communication. Thirdly, while lesbians value 'the relational self', a confident sense of self is challenged when close-connected relationships sit at odds both with mainstream, heterocentric culture, and with traditional models of psychology which promote independence and separateness.Lesbians who are confident communicators, who have access to alternative feminist discourses which value relatedness, and who, together with their friends, are open to change, are able to negotiate satisfactory friendships and relationships. The study demonstrates lesbians' complex subjectivities as changing selves are negotiated through friendships, love relationships and communities, particularly through experiences of loss.

description: In this work, we propose two possibilities of CPT-odd and Lorentz-violating (LV) nonminimal couplings in the Electroweak sector. These terms are gauge-invariant and couple a fixed 4-vector to the physical fields of the theory. After determining the LV contributions to the electroweak currents, we reassess the evaluation of the decay rate for the vector mediators $W$ and $Z$. Using the experimental uncertainty in these decay rates, upper bounds of $1$ part in $10^{-15}$ (eV )$^{-1}$ and $10^{-14}$ (eV )$^{-1}$ are imposed on the magnitude of the proposed nonmimal interactions.

description: We analyse 38-month of contiguous short-cadence data, concentrating on mode multiplets induced by the star rotation and on frequencies forming linear combinations that show intriguing behaviors during the course of the observations. We find clear signatures that point toward nonlinear effects predicted by resonant mode coupling mechanisms. These couplings can induce various mode behaviors for the components of multiplets and for frequencies related by linear relationships. We find that a triplet at 5760\,$μ$Hz, a quintuplet at 5287\,$μ$Hz and a ($\ell>2$) multiplet at 5412\,$μ$Hz, all induced by rotation, show clear frequency and amplitude modulations which are typical of the so-called intermediate regime of a resonance between the components. One triplet at 316\,$μ$Hz and a doublet at 394\,$μ$Hz show modulated amplitude and constant frequency which can be associated with a narrow transitory regime of the resonance. Another triplet at 519\,$μ$Hz appears to be in a frequency lock regime where both frequency and amplitude are constant. Additionally, three linear combination of frequencies near 6076\,$μ$Hz also show amplitude and frequency modulations, which are likely related to a three-mode direct resonance. The identified frequency and amplitude modulations are the first clear-cut signatures of nonlinear resonant couplings occurring in pulsating hot B subdwarf stars. However, the observed behaviors suggest that the resonances occurring in these stars usually follow more complicated patterns than the simple predictions from current nonlinear theoretical frameworks. These results should therefore motivate further work to develop the theory of nonlinear stellar pulsations, considering that stars like KIC~10139564 now offer remarkable testbeds to do so.

description: We present a state-of-the-art calculation of the next-to-leading-order electroweak corrections to ZZ production, including the leptonic decays of the Z bosons into $μ^+μ^-\mathrm{e}^+\mathrm{e}^-$ or $μ^+μ^-μ^+μ^-$ final states. We use complete leading-order and next-to-leading-order matrix elements for four-lepton production, including contributions of virtual photons and all off-shell effects of Z bosons, where the finite Z-boson width is taken into account using the complex-mass scheme. The matrix elements are implemented into Monte Carlo programs allowing for the evaluation of arbitrary differential distributions. We present integrated and differential cross sections for the LHC at 13 TeV both for an inclusive setup where only lepton identification cuts are applied, and for a setup motivated by Higgs-boson analyses in the four-lepton decay channel. The electroweak corrections are divided into photonic and purely weak contributions. The former show the well-known pronounced tails near kinematical thresholds and resonances; the latter are generically at the level of $\sim-5\%$ and reach several $-10\%$ in the high-energy tails of distributions. Comparing the results for $μ^+μ^-\mathrm{e}^+\mathrm{e}^-$ and $μ^+μ^-μ^+μ^-$ final states, we find significant differences mainly in distributions that are sensitive to the $μ^+μ^-$ pairing in the $μ^+μ^-μ^+μ^-$ final state. Differences between $μ^+μ^-\mathrm{e}^+\mathrm{e}^-$ and $μ^+μ^-μ^+μ^-$ channels due to interferences of equal-flavour leptons in the final state can reach up to $10\%$ in off-shell-sensitive regions. Contributions induced by incoming photons, i.e. photon-photon and quark-photon channels, are included, but turn out to be phenomenologically unimportant.

The combined Bayesian analysis of the three measurements sets improved half-life limits for the $2νββ$ and $0νββ$ decay modes of the $2^+_1$, $0^+_1$ and $2^+_2$ transitions in $^{110}$Pd to $2.9\cdot10^{20}$ yr, $4.0\cdot10^{20}$ yr and $3.0\cdot10^{20}$ yr respectively and in $^{102}$Pd to $7.6\cdot10^{18}$ yr, $8.8\cdot10^{18}$ yr and $1.4\cdot10^{19}$ yr respectively with 90% credibility.

description: В статье на основе анализа института государственных закупок при реализации национальных проектов выявляются причины рисков заключения органами государственной власти Российской Федерации контрактов с недобросовестными подрядчиками. Автор акцентирует внимание на том, что сложившаяся мировая практика определяет закупочную деятельность одним из важных факторов, влияющих на скорость и эффективность экономического прогресса независимо от степени их участия в рыночных отношениях. В наиболее развитых странах государственные закупки, несмотря на взаимосвязь между национальными особенностями и различными механизмами системы финансирования государственных закупок и особенностями их взаимодействия, широко используются для обеспечения экономической и социальной стабильности, поступательного экономического роста. Актуальность данной темы обосновывается и тем, что значительная часть мероприятий в рамках национальных проектов осуществляется посредством проведения закупочных процедур. Делается вывод о том, что в процессе реализации вышеуказанных мероприятий органы государственной власти сталкиваются с рядом проблем, в том числе, таких как незащищенность от заключения контрактов с недобросовестными подрядчиками и риски поставок некачественных товаров, некачественного предоставления услуг, срыва сроков реализации взаимосвязанных мероприятий.

description: Many asteroids are likely rubble-piles that are a collection of smaller objects held together by gravity and possibly cohesion. These asteroids are seismically shaken by impacts, which leads to excitation of their constituent particles. As a result it has been suggested that their surfaces and sub-surface interiors may be governed by a size sorting mechanism known as the Brazil Nut Effect. We study the behavior of a model asteroid that is a spherical, self-gravitating aggregate with a binary size-distribution of particles under the action of applied seismic shaking. We find that above a seismic threshold, larger particles rise to the surface when friction is present, in agreement with previous studies that focussed on cylindrical and rectangular box configurations. Unlike previous works we also find that size sorting takes place even with zero friction, though the presence of friction does aid the sorting process above the seismic threshold. Additionally we find that while strong size sorting can take place near the surface, the innermost regions remain unsorted under even the most vigorous shaking.

description: The advent of the Web brought about major changes in the way people search for jobs and companies look for suitable candidates. As more employers and recruitment firms turn to the Web for job candidate search, an increasing number of people turn to the Web for uploading and creating their online resumes. Resumes are often the first source of information about candidates and also the first item of evaluation in candidate selection. Thus, it is imperative that resumes are complete, free of errors and well-organized. We present an automated resume evaluation tool called "CareerMapper". Our tool is designed to conduct a thorough review of a user's LinkedIn profile and provide best recommendations for improved online resumes by analyzing a large number of online user profiles.

description: Using state-of-the-art many-body Green's function calculations based on the "GW plus cumulant" approach, we analyze the properties of plasmon satellites in the electron spectral function resulting from electron-plasmon interactions in one-, two- and three-dimensional systems. Specifically, we show how their dispersion relation, lineshape and linewidth are related to the properties of the constituent electrons and plasmons. To gain insight into the many-body processes giving rise to the formation of plasmon satellites, we connect the "GW plus cumulant" approach to a many-body wavefunction picture of electron-plasmon interactions and introduce the coupling-strength weighted electron-plasmon joint-density states as a powerful concept for understanding plasmon satellites.

description: Abstract: The study of perfection, progress and evolution is a central theme in the history of ideas. This thesis explores this theme seen and understood as part of a discourse in the new fields of anthropology, sociology and psychology in the nineteenth century. A particular focus is on the stance taken by philosophers, scientists and writers in the discussion of theories of human physical and mental evolution, as well as on their views concerning the nature of social progress and historical change. The wisdom and feasibility of improving the human species is discussed alongside an analysis of new methods of investigating and measuring physical and mental attributes of the human organism.The instruments used to assess the development of mind, body and society are described, and are viewed as part of an increased emphasis on the use of technology as an integral part of modern life, and as a means toward the ordered gathering of information in social-scientific practice. An international perspective is taken by observing the way in which ideas about the physical and mental development of humankind was discussed in light and consequence of English and European scientific exploration in the Southern Hemisphere. Further, an evaluation is made of the manner of the spread of new thought in the social sciences from the intellectual and cultural 'centre' of England and Europe to the Anglo-European community located at the 'periphery' in Australia in the late nineteenth century. In particular the educative role played by the non-professional enthusiast as a pivotal conduit for the dissemination of these ideas is highlighted and linked back to a significant tradition of amateur scholarship as a central phenomenon in the study of the history of ideas.

Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy, Institute for Education (Bundoora Campus).

description: With the increasing dissemination and usage of online mate choice, finding a partner via the Internet has attracted remarkable public attention in the last decade. Several, mostly negative prejudices toward online mate choice – especially regarding its risks and disadvantages – circulate constantly throughout the mass media and form public perceptions. This article presents common stereotypes on this (still) new phenomenon, derived from an investigation of newspapers online and offline, online guides, blogs, and discussion forums and confronts them with the empirical facts. Based on several descriptive analyses, we discuss whether and to what extent ten prevalent beliefs correspond to the empirical reality of finding a mate via the Internet in Germany. Zusammenfassung Mit ihrer wachsenden Verbreitung ist die Partnerwahl im Internet zu einem bemerkenswerten Gegenstand des öffentlichen Diskurses geworden. Viele, meist negativ konnotierte Annahmen über die Eigenschaften und den Ablauf der Partnerwahl im Internet, insbesondere hinsichtlich ihrer Risiken und Nachteile, zirkulieren heute in den Medien und beeinflussen deren öffentliche Wahrnehmung. In diesem Beitrag präsentieren wir weit verbreitete Stereotype zum (immer noch) neuen Phänomen der Partnerwahl im Internet. Diese Klischees und Vorurteile, die in (Online-) Zeitungen und Zeitschriften, Online-Ratgebern, Blogs und Diskussionsforen recherchiert wurden, werden mit empirischen Fakten konfrontiert. Basierend auf verschiedenen deskriptiven Analysen diskutieren wir, ob bzw. inwieweit zehn populäre Vorstellungen mit der empirischen Realität der digitalen Partnersuche in Deutschland übereinstimmen.

description: We briefly review the formation of pion-mediated heavy-light exotic molecules with both charm and bottom, under the general strictures of chiral and heavy quark symmetries. The charm isosinglet exotic molecules with $J^{PC}=1^{++}$ binds, which we identify as the reported neutral $X(3872)$. The bottom isotriplet exotic with $J^{PC}=1^{+-}$ binds, and is identified as a mixed state of the reported charged exotics $Z^+_b(10610)$ and $Z^+_b(10650)$. The bound bottom isosinglet molecule with $J^{PC}=1^{++}$ is a possible neutral $X_b(10532)$ to be observed.

description: We use Monte Carlo simulations and free-energy techniques to show that binary solutions of penta- and hexavalent two-dimensional patchy particles can form thermodynamically stable quasicrystals even at very narrow patch widths, provided their patch interactions are chosen in an appropriate way. Such patchy particles can be thought of as a coarse-grained representation of DNA multi-arm `star' motifs, which can be chosen to bond with one another very specifically by tuning the DNA sequences of the protruding arms. We explore several possible design strategies and conclude that DNA star tiles that are designed to interact with one another in a specific but not overly constrained way could potentially be used to construct soft quasicrystals in experiment. We verify that such star tiles can form stable dodecagonal motifs using oxDNA, a realistic coarse-grained model of DNA.
Participation and Non-Participation in Climate Smart Agriculture in a Zambian Farming Community: A Phenomenological Study in Risk Communication

description: Abstract This study aimed at understanding participation and non-participation in climate-smart agriculture through the lens of Phenomenological Tradition of Communication Theory which conceives communication as an experience of self and others in dialogue. It attempted to answer two questions: What are the views of farmers on Climate Smart Agriculture in a Zambian farming community? How do their views define participation and non-participation in climate-smart agriculture? I used qualitative research, particularly, field observations and in-depth conversations with two farmers. I identified repeated statements and phrases from the farmers' conversations and narratives and woven them into themes that described the views of farmers in climate smart agriculture. Two themes constituted the views of farmers on climate smart agriculture: an "acquired or learned experience" with potential for a good harvest and was dependent on the blessing from the spiritual beings, and it defined the action of participation; and "compromising and non-adherence" towards the well-being of the land, whereas the spiritual beings responded with punishment in form of rainfall anomalies, increased droughts and other eschatological consequences, and this defined the action of non-participation. This can be explained through the lens of Phenomenological Tradition of Communication Theory that farmers were in dialogue with the spiritual beings who did not want to be displeased when farmers engaged in climate smart agriculture. This, therefore, explained Risk communication as an interpretive and communicative action of people's real lived experiences, occurring in a contextualized situation, to gain meaning of their desired action to prevent or minimize the effects of potential consequences of risks on their existence. Understanding Risk communication in his way, explains a new communication view called the Phenomenological view of Risk Communication; where people's real lived experiences, based on their contextualized situation, are interpreted and meaning is gained to make farmers in risk environments, to prevent or minimize effects of risks on their existence.
Chemisorption of water on the surface of silicon microparticles measured by DNP-enhanced NMR

description: We use dynamic nuclear polarization (DNP) enhanced nuclear magnetic resonance (NMR) at liquid helium temperatures to directly detect hydrogen attached to the surface of silicon microparticles. The proton NMR spectrum from a dry sample of polycrystalline silicon powder (1-5 $μ$m) shows a distinctively narrow Lorentzian-shaped resonance with a width of 6.2 kHz, indicative of a very sparse distribution of protons attached to the silicon surface. These protons are within a few atomic monolayers of the silicon surface. The high sensitivity NMR detection of surface protons from low surface area ($0.26 - 1.3 \: m^2/g$) particles is enabled by an overall signal enhancement of 4150 over the room temperature NMR signal at the same field. When the particles were suspended in a solvent with 80% H2O and 20% D2O, the narrow peak was observed to grow in intensity over time, indicating growth of the sparse surface proton layer. However, when the particles were suspended in a solvent with 20% H2O and 80% D2O, the narrow bound-proton peak was observed to shrink due to exchange between the surface protons and the deuterium in solution. This decrease was accompanied by a concomitant growth in the intensity of the frozen solvent peak, as the relative proton concentration of the solvent increased. When the particles were suspended in the organic solvent hexane, the proton NMR spectra remained unchanged over time. These results are consistent with the known chemisorption of water on the silicon surface resulting in the formation of hydride and hydroxyl species. Low-temperature DNP NMR can thus be used as a non-destructive probe of surface corrosion for silicon in aqueous environments. This is important in the context of using silicon MEMS and bioMEMS devices in such environments, for silicon micro- and nano-particle MRI imaging agents, and the use of nanosilicon for splitting water in fuel cells.

description: We show that the subgroup lattice of any finite group satisfies Frankl's Union-Closed Conjecture. We show the same for all lattices with a modular coatom, a family which includes all supersolvable and dually semimodular lattices. A common technical result used to prove both may be of some independent interest.
