description: Spin models are the prime example of simplified manybody Hamiltonians used to model complex, real-world strongly correlated materials. However, despite their simplified character, their dynamics often cannot be simulated exactly on classical computers as soon as the number of particles exceeds a few tens. For this reason, the quantum simulation of spin Hamiltonians using the tools of atomic and molecular physics has become very active over the last years, using ultracold atoms or molecules in optical lattices, or trapped ions. All of these approaches have their own assets, but also limitations. Here, we report on a novel platform for the study of spin systems, using individual atoms trapped in two-dimensional arrays of optical microtraps with arbitrary geometries, where filling fractions range from 60 to 100% with exact knowledge of the initial configuration. When excited to Rydberg D-states, the atoms undergo strong interactions whose anisotropic character opens exciting prospects for simulating exotic matter. We illustrate the versatility of our system by studying the dynamics of an Ising-like spin-1/2 system in a transverse field with up to thirty spins, for a variety of geometries in one and two dimensions, and for a wide range of interaction strengths. For geometries where the anisotropy is expected to have small effects we find an excellent agreement with ab-initio simulations of the spin-1/2 system, while for strongly anisotropic situations the multilevel structure of the D-states has a measurable influence. Our findings establish arrays of single Rydberg atoms as a versatile platform for the study of quantum magnetism.

Examining the Role of Transcriptional Interference in HIV Latency

description: The establishment of a latent reservoir after infection by Human Immunodeficiency Virus type 1 (HIV-1) is a significant obstacle to an HIV cure. Antiretroviral therapies (ART) effectively target actively replicating virus, but are ineffective at targeting latently infected cells. Thus, an area of key interest lies in developing methods to induce expression of these latent proviruses. As such, an understanding of the molecular mechanisms which govern HIV transcription is of interest to identify new targets to mediate latency reversal. The aim of this research was to investigate the effect of transcriptional interference on HIV latency in cell models with characterized integration sites. In the model organism Saccharomyces cerevisiae (yeast), regulation of transcription involves a complex set of proteins that creates heterochromatin in regions after they have been transcribed to prevent cryptic transcription—transcription initiation in non-promoter regions. Evidence suggests this mechanism works in a similar capacity in humans, and we hypothesized this may contribute to HIV latency. Using CRISPR-Interference, we targeted a nuclease-deactivated Cas9 protein (dCas9) fused to the KRAB transcriptional repression domain to promoter regions of known genes of HIV integration to silence host gene transcription and examine the role of transcriptional interference in HIV latency. Cell lines expressing dCas9-KRAB and both single and multiple gRNAs targeted to host gene promoters showed moderate to high reduction of mRNA expression of the host gene of HIV integration but did not fully ablate transcription. In these systems, we did not observe an altered response in latency reversal. If transcriptional interference does indeed have an effect on latency, then it appears that merely diminishing transcription is not sufficient to alter reactivation, or that transcriptional interference plays a minor overall role in maintenance of latency.

description: Primary production is integral to feeding and clothing the world, and cotton is both a food and a fibre. The cotton industry’s producer employers are critical to the longevity of the Australian cotton industry. Understanding their motivation and the influencers of their decision-making processes in crop choice is important. While exploring decision-making of employers is not new, this study seeks to establish what are the sources of motivation to grow cotton and what factors influence the decision-making processes in the context of cotton grower employer (CGE) crop choice. The work is framed as exploratory and theory building, as little has been published in the academic literature about individual employer perspectives in agriculture, such as CGEs and how they are influenced from a psychological and behavioural economic perspective. There is a deficit specifically regarding individual employer experiences from this perspective in Australian agriculture broadly and in cotton growing more specifically. Overall, this multi-disciplinary study has identified influencers that impact on the decision-making processes of CGEs. This research is important because it informs cotton industry stakeholders such as (a) growers and their supportive others, (b) industry service providers such as merchants, ginners, brokers and insurers, and (c) government policy-makers regarding the influences of CGE decision-making processes and crop choice.

description: Since its inception as an independent nation, Tanzania, or Tanganyika, has had leadersinterested in the place of education in a democratic nation. After assuming control of its own educationsystem, not only did the Tanzanian people capitalize on the existing global rights discourse, butTanzanian thinkers generativity added to that discourse, espousing a vision of education that accountedfor the way in which economic instability changes the capacity of states to fulfill to provide education,while not reducing the necessity of education. The case of Tanzania also serves a reminder of the waysin which national education systems can serve as locations of transnational influence as local interestsinteract with international intrigue and politics. Tanzania does not represent a utopic education systemfor poor nations or a monolithic resonance across the global south, but it does serve as an effectivereminder that the ideals of post-independence African states were not universally doomed. From the start of independence through the early 1970s, Tanzania prioritized education among its politicalcommitments and the education system rapidly expanded both in length of coursework and number ofstudents while breaking down pre-existing barriers. Tanzanian leaders justified these efforts both on thebasis of economic development and human rights, a mix that would have later consequences.

description: This research contributes to the understanding of how Australian sugarcane farmers conceive of their management of the impacts of the highly variable climate in which their businesses are situated. The historical group extension and information communication environment which support farmer discussions and consideration of climate information is described, particularly in the way in which participative Managing for Climate Risk workshops have been delivered in Queensland, Australia. The decline in the provision of traditional extension services is discussed, and the consequent opportunity that improvements in digital networks provide to augment and or replace extension services with different communication tools. Novel discussion support tools (a series of four machinima, animations produced in a virtual world format) are developed, evaluated and tested in a farmer workshop, delivered in a collaborative, social learning environment, using adult learning principles. Developmental phenomenography is used as the principal qualitative research methodology to understand and describe farmer conceptions of managing and discussing climate risk. Post-workshop survey and semi-structured interview data are analysed phenomenographically within the research to articulate the variation in farmer conceptions to related phenomena. Conclusions and recommendations for the climate science and communication community are developed which may lead to improvements in the ways that farmers are engaged and supported in their learning about managing the impacts of climate variability in the future. Additionally, the opportunity to use phenomenography as a qualitative evaluation methodology in agriculture extension programs is discussed.

description: The next-to-minimal supersymmetric standard model (NMSSM) with an extended Higgs sector offers one of the Higgs boson as the Standard model (SM) like Higgs with a mass around 125 GeV along with other Higgs bosons with lighter and heavier masses and not excluded by any current experiments. At the LHC, phenomenology of these non SM like Higgs bosons is very rich and considerably different from the other supersymmetric models. In this work, assuming one of the Higgs bosons to be the SM like, we revisit the mass spectrum and couplings of non SM like Higgs bosons taking into consideration all existing constraints and identify the relevant region of parameter space. The discovery potential of these non SM like Higgs bosons, apart from their masses, is guided by their couplings with gauge bosons and fermions which are very much parameter space sensitive. We evaluate the rates of productions of these non SM like Higgs bosons at the LHC for a variety of decay channels in the allowed region of the parameter space. Although bb, ττ decay modes appear to be the most promising, it is observed that for a substantial region of parameter space the two-photon decay mode has a remarkably large rate. In this work we emphasize that this diphoton mode can be exploited to find the NMSSM Higgs signal and can also be potential avenue to distinguish the NMSSM from the MSSM. In addition, we discuss briefly the various detectable signals of these non SM Higgs bosons at the LHC.

description: Mixtures of polarised fermions of two different masses can form weakly-bound clusters, such as dimers and trimers, that are universally described by the scattering length between the heavy and light fermions. We use the resonating group method to investigate the low-energy scattering processes involving dimers or trimers. The method reproduces approximately the known particle-dimer and dimer-dimer scattering lengths. We use it to estimate the trimer-trimer scattering length, which is presently unknown, and find it to be positive.

Facebook and the Effects of a Media Literacy Intervention on Body Dissatisfaction

description: It is well known that mass media, such as advertisements, magazines and television, portray women in an unrealistic way by selecting models that are uniformly thin and beautiful, and also by using photo editing techniques to alter their faces and bodies. When women socially compare to the images they see in mass media, their body dissatisfaction increases. Media literacy interventions have been successful in buffering this body dissatisfaction effect by raising awareness of photo editing and unrealistic ideals of thinness and beauty. Novel forms of media, such as social networking sites like Facebook, also facilitate an environment where individuals socially compare to unrealistic images of their peers, given that individuals post mostly flattering pictures of themselves. This experimental study evaluated the effects of a media literacy intervention for Facebook, hypothesizing that the media literacy intervention would buffer hypothesized body dissatisfaction effects of Facebook, in particular for those directed to view attractive Facebook friends. Trend-level findings suggest that those who received the media literacy intervention and viewed attractive peers demonstrated the lowest appearance self-esteem after viewing Facebook. Future research must be conducted to better understand the effects of Facebook on body image and effective media literacy interventions for social media sites like Facebook.

description: We use the Spitzer Survey of Stellar Structure in Galaxies (S$^{4}$G) 3.6 $μ$m imaging to study the properties (length and strength) and fraction of bars at $z=0$. We use the maximum of tangential-to-radial force ratio in the bar region ($Q_{\rm b}$) as a measure of the bar induced perturbation strength for a sample of $\sim 600$ barred galaxies. Bars are also characterized from the maximum of the normalized m=2 Fourier density amplitude ($A_{2}^{\rm max}$) and the bar maximum isophotal ellipticity ($\varepsilon$). Combining our force calculations with the HI kinematics from the literature we get an estimate of the halo-to-stellar mass ratios ($M_{\rm h}/M_{\ast}$) within the optical disk, which are in good agreement with studies based on weak lensing analysis, abundance matching and halo occupation distribution methods. By further using the Universal Rotation Curve models we obtain a first-order model of the rotation curve decomposition of $1128$ disk galaxies. We find that the dilution of $Q_{\rm b}$ by the halo becomes important for later types, implying $\sim 20-25\%$ reduction for $T = 7-10$. Whether the halo correction is included or not, the mean $Q_{\rm b}$ shows an increasing trend with $T$. Late-type bars are longer than previously found in the literature. We find possible evidence for the growth of bars within a Hubble time, as (1) bars in early-type galaxies show larger density amplitudes and disk-relative sizes than their intermediate-type counterparts, and (2) long bars are typically strong. We also observe two clearly distinct types of bars, between early and intermediate-type galaxies ($T<5$) on one side, and the late-type systems on the other, based on the differences in the bar properties. Most likely this distinction is connected to the larger halo-to-stellar ratio that we observe in later types, affecting the disk stability properties (Abridged).

description: The Jehol Biota represents an important phase in the history of biological evolution on Earth. Two sites with Aptian Jehol Biota, located in western Liaoning Province and in northern Hebei Province, northeastern China, have generated a major debate about the relationships between their fossil-bearing layers, resulting in confusions about their stratigraphic correlation and biogenetic sequence. We have applied carbon isotope analysis of total organic carbon to provide new data relevant to this debate and have re-examined the connection between volcanism and carbon cycle perturbations, with consideration of the paleoenvironmental conditions. The rare earth element data show that the provenances of the Jehol Group in western Liaoning and northern Hebei were similar and derived mainly from the underlying andesite. Constrained by the radiometric age, the δ13Corg curve suggests that the Dadianzi Formation in northern Hebei is comparable to the three lacustrine layers of the Yixian Formation (ranging from the Jianshangou Bed to the Jingangshan Bed) in western Liaoning. These layers are highly correlated with the early Aptian marine sequence in Oceanic Anoxic Event 1a (OAE 1a), implying that a possible teleconnection (possibly related to a large igneous province) existed between oceanic and terrestrial realms. We also propose that the Xiguayuan Formation above the Dadianzi Formation in northern Hebei is equivalent to the Huanghuashan Breccia Bed at the top of the Yixian Formation in western Liaoning. Moreover, the δ13Corg and element geochemical data suggest that the carbon cycle perturbation and the paleolimnological environments were distinctly influenced by the effects of volcanic CO2 during the early Aptian.
title: Building capacity for year 9 reform: learning from the teachers’ perspectives

description: In Australia, Year 9 is generally the third year of secondary school catering for students aged 14-15 years. Year 9 has been identified in the literature as a problematic period with high levels of student is engagement, absenteeism and teacher stress. In order to improve Year 9 education, some Australian schools have instigated separate campus programmes dedicated solely to Year 9. This instrumental case study centred on a Tasmanian independent school that engaged in such reform. Whilst research regarding the middle years of schooling (Years 5-9) has grown significantly in Australia over recent decades, studies on middle years’ reform have often neglected teachers’ voices. This study examined the process of Year 9 reform with a specific emphasis on the teachers’ perspectives, recognising that teachers are the key agents in enacting school change. The study was underpinned by constructivist inquiry and collected qualitative data from multiple sources, using the tools of: full participant observations, semistructured interviews, school document analysis and Email dialogues. The researcher gained full access and participation in the Year 9 reform as a teacher employed at the case school. From the teachers’ perspectives, this study uncovered the case school’s rationale and vision for Year 9 reform; eight key roles teachers play in reform; and factors that contribute to capacity building for successful change. The findings of this study resulted in two significant recommendations for reform in the middle years. Firstly, in order for reform to be holistic and successful, schools need to adopt a strategic, research-guided approach that involves teachers at every stage. Secondly, schools need to take a three-fold approach to capacity building so that all facets of capacity – personal, interpersonal and organisational – are duly developed for successful change. This study provided the first Tasmanian perspective on the rationale and vision for Year 9 reform. Importantly, it identified eight key roles that teachers play during reform and gave recommendations on how these roles could be enhanced for greater teacher leadership. The findings of this study are significant for future middle years’ reform; the generation of theory on the roles of teachers in reform; and rationale and vision for Year 9 reform in Australia.
Populist Appeals to Europe and their Implications, 1883-1908

description: In 1899, three years after their most significant electoral defeat, the Populist movement appeared to be past its prime. American intellectuals started to look back at the movement and identify its influences, origins and the impact that it could have on the future of the American political system. Kansas Populist Carl Vrooman wrote on all three of these notions in an article in the Populist magazine The Arena entitled “Twentieth Century Democracy.” Vrooman dedicated his article to a general analysis of the movement while particularly focusing on what Populists read, what they did and what their example meant for the upcoming century. In one section, he devotes a considerable amount of space to the role of Populist thought not only in the United States but around the world.  This idea appeared once again in another work by Vrooman where he wrote, “Many of the principles advocated by the Populists have had as their champions such statesmen as Bismarck, Gladstone, Chamberlain…”  Such a statement made by a well-connected Populist leader, one whose works gained inclusion into the Congressional Record on one occasion, challenges one of the dominant assumptions of Populist historiography: its American roots in terms of argument and rhetoric for policies. Historians of Populism over the past century focused almost exclusively on the American basis of Populist rhetoric.  This appeal to Europe, however, is supported by a number of different appeals to European leaders found in the works of Populist intellectual and political leaders. Such appeals to Europe are key to understanding the intellectual framework of Populism and hint at the reasoning behind Populist policies and rhetoric.
  In order to better understand the place of Europe within this framework, one must begin at the early days of the Populist movement (by which I mean the late-19th and early-20th century reform movement led mostly by farmers under the leadership of the People’s Party). How did these leaders articulate the grievances that they professed against the political, social and economic systems of their day? What models of social protest from American history could they draw from and were those models sufficient? Then, once the Populists became a more coherent movement, how did they play on capturing power and what did they want to do when they did capture power? Finally, how did they cope with the losses that led to the eventual collapse of their movement? I believe that the many references and appeals to European leaders found in Populist works, especially the three cited by Vrooman, help to answer these questions and also better classify the place of the movement in its historical and political context.
The Effect of Exercise on the Antibody Response to Influenza Vaccine in Type 2 Diabetics

description: Obesity is a growing health problem that is affecting over one third of the adult population in the United States. Obesity increases an individual’s risk for diseases such as hypertension, cardiovascular disease, and type 2 diabetes. The prevalence of type 2 diabetes is growing in a trend similar to obesity in the United States. Obesity and type 2 diabetes has been shown to be immunosuppressive and increase an individual’s susceptibility to influenza infection. Increased physical activity and exercise has been shown to decrease the risks for complications associated with obesity and type 2 diabetes as well as increasing immune function. In the present pilot study we wanted to look at the differences in antibody response between obese non-diabetics and obese diabetics based on exercise and physical activity. To do this we collected serum from obese non-diabetics and obese diabetics pre- and post-vaccination of the influenza vaccine and used an ELISA assay to determine the response of the four subclasses Immunoglobulin G antibodies to the influenza vaccine pre- and post-vaccination of influenza vaccine. We found that vaccination for influenza resulted in a significant change in IgG1 and IgG3 serum titer. We found the amount of exercise did not result in significant changes in serum titer for any of the four IgG subclasses. Future studies should be conducted to determine defined relationship between exercise and immune response to influenza in obese and type 2 diabetics.

description: We propose a scheme for laser cooling of negatively charged molecules. We briefly summarise the requirements for such laser cooling and we identify a number of potential candidates. A detailed computation study with C$\_2^-$, the most studied molecular anion, is carried out. Simulations of 3D laser cooling in a gas phase show that this molecule could be cooled down to below 1 mK in only a few tens of milliseconds, using standard lasers. Sisyphus cooling, where no photo-detachment process is present, as well as Doppler laser cooling of trapped C$\_2^-$, are also simulated. This cooling scheme has an impact on the study of cold molecules, molecular anions, charged particle sources and antimatter physics.

This allowed for the identification of characteristic Stokes lines for titania and polystyrene nanoparticles, showing the capability for material identification of nanoparticles once trapped. Increased Raman signal is observed for the trapping of multiple nanoparticles. This system combines the benefits of nanoparticle isolation and manipulation with unique identification.

description: Adolescence is a period in which students experience physical and intellectual changes and adopt long-term health habits. This study examines the relationship between health education taught in schools and health behavior outcomes of adolescents. Data was used from Wave I of the National Longitudinal Study of Adolescent Health to Adult Health for adolescents in grades 7-12. Eight health lessons were identified along with associated health behavior outcomes. Of the 15 multiple regression analyses conducted in Wave I, 6 associations were statistically significant. A positive relationship between learning about the foods you should and should not eat and eating properly was supported. Additionally, a positive relationship between learning about the importance of exercise and student activity levels was supported. Negative relationships between learning about drug abuse and student use of cocaine and inhalants were also supported. A positive relationship between learning about smoking and ever having tried a cigarette was supported. Of the multiple regression analyses conducted in Wave II, 2 associations were statistically significant. Learning about the importance of exercise was positively correlated with body image, and receiving all 8 health lessons in Wave I was positively associated with overall health. Student gender, race, and grade level were controlled in each multiple regression analysis. This study offers some support for the influence of health lessons taught in school on adolescent health behavior outcomes.

description: The Neptune Trojans are a population of small bodies that librate around the L4 and L5 Lagrange points of Neptune’s orbit. Shortly after the discovery of the first such object, 2001 QR322, simulations suggested that the body moved on a dynamically stable orbit. Following this, further discovered objects were generally assumed to also be stable. In recent years, the situation has proved to be more complicated than previously thought. Two of Neptune’s Trojans have been found to exhibit orbital instability on billion year timescales, with another being revealed as a temporarily captured interloper. Here, the results of detailed dynamical simulations of the orbital evolution of the eleven known Neptunian Trojans are presented, examining the influence of their initial orbital semi-major axes and eccentricities on their stability. The results reveal the importance of considering the orbital stability of newly discovered objects on a case-by-case basis, with some members showing highly unstable behaviour, whilst others seem likely to be primordial in nature. The earlier finding that 2001 QR322 and 2008 LC18 are primordial in nature but unstable on billion year timescales are confirmed. In both cases, their stability is a strong function of their semi-major axis, with the two lying on the boundary between stable and unstable regions. In addition we reveal the stability of eight other Neptune Trojans. Six of the known Trojans move on highly stable orbits. In contrast, two objects, 2004 KV18 and 2010 EN65, are confirmed to be temporarily captured members of the Neptune's Trojan population. While one, 2012 GX17, is found to be a misidentified Trans-Neptunian Object.

description: In the traditional statistical framework, nonsignificant results leave researchers in a state of suspended disbelief. This study examines, empirically, the treatment and evidential impact of nonsignificant results. Our specific goals were twofold: to explore how psychologists interpret and communicate nonsignificant results, and to assess how much these results constitute evidence in favor of the null hypothesis. Firstly, we examined all nonsignificant findings mentioned in the abstracts of the 2015 volume of Psychonomic Bulletin & Review, Journal of Experimental Psychology: General, and Psychological Science (N = 137). In 72% of cases, nonsignificant results were misinterpreted, in the sense that authors inferred that the effect was absent. Secondly, a Bayes factor reanalysis revealed that fewer than 5% of the nonsignificant findings provided strong evidence (i.e., BF01 > 10) in favor of the null hypothesis compared to the alternative hypothesis. We recommend that researchers expand their statistical toolkit in order to correctly interpret nonsignificant results and to be able to evaluate the evidence for and against the null hypothesis.

description: Continuous learning is essential for registered nurses to maintain knowledge of current best practice, and therefore facilitate the best possible outcomes for patients. Gaining access to learning, and the time to engage in learning, requires the nurse to contribute personal resources such as time and money. Nurses often have limited access to learning while at work due to staffing levels and the fast pace of the work environment. They often have limited resources outside of work hours to contribute to their learning. Therefore alternative strategies for learning need to be explored to enable the nurse to continuously learn. This research sought to discover how registered nurses were currently using mobile devices in their work and private lives, to ascertain if mobile learning would be of value in nursing education and where it would be best used. Nurses mostly did not have concerns about using mobile devices, however, it became evident in interviews that they were mostly concerned with maintaining competence with limited resources. This classic grounded theory research revealed that nurses economise learning to enable them to address their concern of maintaining competence with limited resources. They achieve this by balancing personal resources against motivational issues within the continuous process of economising learning. The process of economising learning commences and ends with the nurse’s personal curriculum, which has been developed throughout the nurse’s career, and is what the nurse identifies as important learning needs within the work area. Nurses become aware of a learning need when their personal curricula are compromised or they become aware of other knowledge that is needed for their work area. The learning opportunity to meet the learning need will be found and balanced by individual nurses, to determine if and how they will engage with the opportunity. Finally nurses will engage or not in the learning and update their personal curricula accordingly. The Theory of Economising Learning, together with the reviewed literature has led to the development of a Healthy Learning Workplace Model to determine and improve the health of the workplace in regard to learning. The model contains the four domains of expectations, current, economical access, and support.

description: Cosmic ray anisotropy has been observed in a wide energy range and at different angular scales by a variety of experiments over the past decade. However, no comprehensive or satisfactory explanation has been put forth to date. The arrival distribution of cosmic rays at Earth is the convolution of the distribution of their sources and of the effects of geometry and properties of the magnetic field through which particles propagate. It is generally believed that the anisotropy topology at the largest angular scale is adiabatically shaped by diffusion in the structured interstellar magnetic field. On the contrary, the medium- and small-scale angular structure could be an effect of non-diffusive propagation of cosmic rays in perturbed magnetic fields. In particular, a possible explanation of the observed small-scale anisotropy observed at TeV energy scale, may come from the effect of particle scattering in turbulent magnetized plasmas. We perform numerical integration of test particle trajectories in low-$β$ compressible magnetohydrodynamic turbulence to study how the cosmic rays arrival direction distribution is perturbed when they stream along the local turbulent magnetic field. We utilize Liouville's theorem for obtaining the anisotropy at Earth and provide the theoretical framework for the application of the theorem in the specific case of cosmic ray arrival distribution. In this work, we discuss the effects on the anisotropy arising from propagation in this inhomogeneous and turbulent interstellar magnetic field.

description: Following the approach of Dahmani, Guirardel and Osin, we extend the group theoretical Dehn filling theorem to show that the pre-images of infinite order elements have a certain structure of a free product. We then apply this result to show that groups hyperbolic relative to residually finite groups satisfying the Farrell-Jones conjecture, they satisfy the Farrell-Jones conjecture.

title: Black gold, the scenic rim and the theory of the firm: implications of the exploration for coal and coal seam gas in the scenic rim of south east Queensland for the evolving theory of the firm

description: The implicit social contract between Australian society, government and business does not provide an environment in which communities within the Scenic Rim of South East Queensland believe that their values and development desires are adequately protected. Consequently, the communities are insisting that their local values, particularly regarding the environment, good quality agricultural land and water, be recognised and respected by both governments and mining companies. This changing social contract has significant implications for: (i) the nature of the engagement between communities and mining companies that might result in a more equitable distribution of both the benefits and disadvantages of mining; and; (ii) the evolving theory of the firm. This change applies particularly to those theories that focus on the reasons for existence of corporations, their relationship with external stakeholders and the values placed on corporate resources. The thesis is based on qualitative research into the values and development desires of communities and companies active within the Scenic Rim of South East Queensland and draws heavily on archival material available from both Australian and Queensland government sources. A model for evaluating the utility of theories of the firm is developed and twelve existing groups of theory are analysed. Few of the theories meet many of the criteria proposed in the model (particularly regarding tests of their validity and reliability) and characteristics of an enhanced theory of the firm applicable to all companies are identified.
Effects on satellite orbits in the gravitational field of an axisymmetric central body with a mass monopole and arbitrary spin multipole moments

description: Perturbations of satellite orbits in the gravitational field of a body with a mass monopole and arbitrary spin multipole moments are considered for an axisymmetric and stationary situation. Periodic and secular effects caused by the central gravitomagnetic field are derived by a first order perturbation theory. For a central spin-dipole field these results reduce to the well known Lense-Thirring effects.
Characteristic Sign Renewals of Kardar-Parisi-Zhang Fluctuations

description: Tracking the sign of fluctuations governed by the $(1+1)$-dimensional Kardar-Parisi-Zhang (KPZ) universality class, we show, both experimentally and numerically, that its evolution has an unexpected link to a simple stochastic model called the renewal process, studied in the context of aging and ergodicity breaking. Although KPZ and the renewal process are fundamentally different in many aspects, we find remarkable agreement in some of the time correlation properties, such as the recurrence time distributions and the persistence probability, while the two systems can be different in other properties. Moreover, we find inequivalence between long-time and ensemble averages in the fraction of time occupied by a specific sign of the KPZ-class fluctuations. The distribution of its long-time average converges to nontrivial broad functions, which are found to differ significantly from that of the renewal process, but instead be characteristic of KPZ. Thus, we obtain a new type of ergodicity breaking for such systems with many-body interactions. Our analysis also detects qualitative differences in time-correlation properties of circular and flat KPZ-class interfaces, which were suggested from previous experiments and simulations but still remain theoretically unexplained.

Non-Diffracting Electron Vortex Beams Balancing Their Electron-Electron Interactions

description: By introducing concepts of beam shaping into quantum mechanics, we show how interference effects of the quantum wavefunction describing multiple electrons can exactly balance the repulsion among the electrons. With proper shaping of the fermionic wavefunction, we propose non-diffracting quantum wavepackets of multiple electrons that can also carry orbital angular momentum, in the form of multi-electron non-diffracting vortex beams. The wavefunction is designed to compensate for both the repulsion between electrons and for the diffraction-broadening. This wavefunction shaping facilitates the use of electron beams of higher current in numerous applications, thereby improving the signal-to-noise-ratio in electron microscopy and related systems without compromising on the spatial resolution. Our scheme potentially applies for any beams of charged particles, such as protons, muons and ion beams.
