description: We analyze the time dependence of fluid variables in general relativistic, magnetohydrodynamic simulations of accretion flows onto a black hole with dimensionless spin parameter a/M=0.9. We consider both the case where the angular momentum of the accretion material is aligned with the black hole spin axis (an untilted flow) and where it is misaligned by 15 degrees (a tilted flow). In comparison to the untilted simulation, the tilted simulation exhibits a clear excess of inertial variability, that is, variability at frequencies below the local radial epicyclic frequency. We further study the radial structure of this inertial-like power by focusing on a radially extended band at 118 (M/10Msol)^-1 Hz found in each of the three analyzed fluid variables. The three dimensional density structure at this frequency suggests that the power is a composite oscillation whose dominant components are an over dense clump corotating with the background flow, a low order inertial wave, and a low order inertial-acoustic wave. Our results provide preliminary confirmation of earlier suggestions that disk tilt can be an important excitation mechanism for inertial waves.

Geospatially enabled modelling of values and decisions in agro-ecological landscapes
Creators: name: Mahboob, J
Publisher: name: University Of Tasmania
Year: 2023

description: Effective resource management requires an understanding of the complex associations that occur between natural ecosystems, managed environments, and a variety of economic, social and political factors. Many aspects of resource management are location dependent. They are defined or affected by physical aspects of the immediate or proximal environment, by statutory or legal aspects of the immediate or proximal location, by economic values associated with location, or by relationships with a potentially large variety of policies that create rights, responsibilities, risks or opportunities associated with location, or with attributes that are associated with location. This study explores the capacity to geospatially enable the representation, analysis and communication of values that inform decision making in complex agro-ecological landscapes. Integrated ecological economic modelling provides one framework in which to account for these various and complex interconnections and interactions. The research begins with a review of spatially enabled integrated ecological economic models to reveal the state-of-the-art and the knowledge gap. A spatially enabled model is then designed to close the knowledge gap and is implemented in software as a tool for application to the analysis of decisions that lead to changes in land use. In order to demonstrate the utility of the model and its implementation, a model farm is constructed that exhibits a variety of land capability and land uses typical of a farm within the Tasmanian Midlands region, Australia. Historical land use records are used to develop land use change scenarios and a semi-structured stakeholder survey is used to collect stakeholder values with which to populate the model. Outputs from this case study show how complex spatial and a-spatial data can be integrated and modelled, to deliver valuable information, to communicate that information both quantitatively and visually in order to inform policy processes. This study contributes to the development of models that can be used in complex decision-making settings and that have capacity to be catalysts for, and to inform and support, dialogue between interested parties, supported by spatial reasoning, and providing for socially, environmentally and economically acceptable solutions.

This is an improvement of more than three orders of magnitude over the best previous result. Additionally, hyperfine-interaction enabling of the forbidden transition has been observed, to our knowledge, for the first time.

description: We examine CEO turnover and succession planning using a unique and highly comprehensive data set from the company exechange. Exechange applies a novel methodology that evaluates the circumstances surrounding a CEO departure to determine the degree to which the turnover event might be voluntary or involuntary (called the Push-Out Score). With this data, we are able to provide new statistics on CEO departures and fresh analysis in three areas of succession planning — sensitivity of turnover to performance, board preparedness to name a successor, and the performance of internal and external successors — to arrive at a more current assessment of the quality of CEO succession planning among publicly traded companies in the U.S.

Linguistical choice in Tasmanian environmental discourse : a study of the prevalence and impact of military terminology in the upper Florentine Valley forestry dispute, 2008-2012
Creators: name: Price, CJ
Publisher: name: University Of Tasmania
Year: 2023

description: The project examines the ubiquity and impact of military discourse in the context of disputation over the fate of natural areas. Though typically tense, anger-inducing and confrontational, do such face-offs merit the label 'war'? It is argued here that they do not; that there are defining features of 'war' that do not apply to its metaphoric deployment in environmental conflict. The nature of metaphor and its discursive purpose and standing are first examined, followed by a consideration of the readiness with which warfare metaphors tend to be applied to a range of non-military situations. Environmental discourse is particularly saturated with metaphors borrowed from warfare. The project takes, as a case study, the dramatic on-site confrontation between (mostly) young forest activists and logging contractors and police in the upper Florentine Valley in the Tasmanian south-west. Protesters set up a permanent camp ‚Äö- 'Camp Florentine' ‚Äö- on the proposed line of access to the gazetted forest coupes, remaining determinedly in occupation for several years until logging operations were, for the time being, halted. Using semi-structured interviews a number of principal actors in the dispute were interviewed. Most, but not all, agreed that the use of military terminology in relation to the dispute was inappropriate. On the question of the impact of the widespread use of warfare-derived metaphors on the psychology and consequent comportment of participants in contestation over environmental goods ‚Äö- in this case, wild forest ecosystems ‚Äö- there was even less consensus.

description: We present a hybrid combination of forward and inverse reconstruction methods using multiple observations of a coronal mass ejection (CME) to derive the 3D 'true' Height-Time plots for individual CME components. We apply this hybrid method to the components of the 31 Dec 2007 CME. This CME, observed clearly in both the STEREO A and STEREO B COR2 white light coronagraphs, evolves asymmetrically across the 15 solar radius field of view with in a span of three hours. The method has two reconstruction steps. We fit a boundary envelope for the potential 3D CME shape using a flux rope-type model oriented to best match the observations. Using this forward model as a constraining envelope, we then run an inverse reconstruction solving for the simplest underlying 3D electron density distribution that can, when rendered, reproduce the observed coronagraph data frames. We produce plots for each segment to establish the 3D or "true" Height-Time plots for each center of mass as well as for the bulk CME motion, and use these plots along with our derived density profiles to estimate the CME asymmetric expansion rate.

description: The main observational evidence for turbulence in the interstellar medium (ISM) and molecular clouds is the power-law energy spectrum for velocity fluctuations, E(k) \propto k^α. The Kolmogorov scaling exponent, α=-5/3, is typical. At the same time, the observed probability distribution function (PDF) of gas densities in both the ISM as well as in molecular clouds is a log-normal distribution, which is similar to the initial mass function (IMF) that describes the distribution of stellar masses. We examine the density and velocity structure of interstellar gas traversed by curved shock waves in the kinematic limit. We demonstrate mathematically that just a few passages of curved shock waves generically produces a log-normal density PDF. This explains the ubiquity of the log-normal PDF in many different numerical simulations. We also show that subsequent interaction with a spherical blast wave generates a power-law density distribution at high densities, qualitatively similar to the Salpeter power-law for the IMF. Finally, we show that a focused shock produces a downstream flow with energy spectrum exponent α=-2. Subsequent shock passages reduce this slope, achieving α\approx -5/3 after a few passages. Subsequent dissipation of energy piled up at the small scales will act to maintain the spectrum very near to the Kolomogorov value. Therefore, fully-developed turbulence may not be required to explain the observed energy spectrum and density PDF. We argue that the self-similar spherical blast wave arising from expanding HII regions or stellar winds from massive stars may ultimately be responsible for creating the high mass, power-law, tail in the IMF.

description: Cannabis sativa L. is a phenotypically diverse and multi-use plant used in the production of fiber, seed, oils, and a class of specialized metabolites known as phytocannabinoids. The last decade has seen a rapid increase in the licit cultivation and processing of C. sativa for medical end-use. Medical morphotypes produce highly branched compact inflorescences which support a high density of glandular trichomes, specialized epidermal hair-like structures that are the site of phytocannabinoid biosynthesis and accumulation. While there is a focus on the regulation of phytocannabinoid pathways, the genetic determinants that govern flowering time and inflorescence structure in C. sativa are less well-defined but equally important. Understanding the molecular mechanisms that underly flowering behavior is key to maximizing phytocannabinoid production. The genetic basis of flowering regulation in C. sativa has been examined using genome-wide association studies, quantitative trait loci mapping and selection analysis, although the lack of a consistent reference genome has confounded attempts to directly compare candidate loci. Here we review the existing knowledge of flowering time control in C. sativa, and, using a common reference genome, we generate an integrated map. The co-location of known and putative flowering time loci within this resource will be essential to improve the understanding of C. sativa phenology.

description: Graphene was recently proposed as a material for heat removal owing to its extremely high thermal conductivity. We simulated heat propagation in silicon-on-insulator circuits with and without graphene lateral heat spreaders. Numerical solutions of the heat propagation equations were obtained using the finite element method. The analysis was focused on the prototype silicon-on-insulator circuits with the metal-oxide-semiconductor field-effect transistors. It was found that the incorporation of graphene or few-layer graphene layers with proper heat sinks can substantially lower the temperature of the localized hot spots. The maximum temperature in the transistor channels was studied as function of graphene's thermal conductivity and the thickness of the few-layer-graphene. The developed model and obtained results are important for the design of graphene heat spreaders and interconnects.

Effects of occlusion of the thoracic aorta on habituation of the flexor withdrawal reflex in the rat
Creators: name: Krajina, Vladimir Peter Jan
Publisher: name: University of British Columbia
Year: 2011

description: Experiments were carried out to investigate the extent to which habituation of the flexor reflex depended on mechanisms operating at spinal interneurones. An attempt was made to cause selective degeneration of interneurones in the spinal cord of the rat by subjecting the cord to a period of ischaemia. Ischaemia was produced by temporary occlusion of the thoracic aorta. The flexor withdrawal reflex was tested 3, 7 or 14 days after occlusion. When compared with data from control animals it was found that ischaemia had resulted in both a qualitative change and a quantitative diminution in the amount of habituation which occurred during the presentation of 400 uniform stimuli. It was concluded that this impairment of the habituation process was a consequence of degeneration of interneurones which normally cause progressive inhibition of the excitatory flexor reflex pathway.

It is demonstrated how a combination of finite-temperature t-DMRG and time-series prediction allows for an easy and very accurate calculation of spectral functions in one-dimensional quantum systems, irrespective of their statistics, for arbitrary temperatures. This is illustrated with spin structure factors of XX and XXX spin-1/2 chains. For the XX model we can compare against an exact solution and for the XXX model (Heisenberg antiferromagnet) against a Bethe Ansatz solution and quantum Monte Carlo data.

description: In this Closer Look, we use the example of VICI Properties — a publicly traded REIT that emerged from the bankruptcy of Caesar’s Entertainment — to examine how appropriate governance choices can change the course of a corporation and establish a foundation for long-term success. We discuss the company’s history, and the decisions the controllers of the company made to establish a board of directors, recruit a leadership team, and develop corporate, financial, and investor relations strategies, and compensation and governance programs. The result of these efforts was that less than five years from bankruptcy emergence, VICI Properties achieved an impressive track record of growth, market value creation, and credit quality improvement that garnered external recognition from investors and analysts for its achievements. We ask: What role did governance choices play in these outcomes? How critical is board quality among publicly traded companies in general and REITs in specific? In what way does executive leadership contribute to corporate success? How important are intangible leadership qualities, such as vision, communication, and consensus-building? How, if at all, does the composition of a company’s shareholder base contribute to performance? Do governance choices tangibly contribute to value creation, or do they simply make skeptical investors “more comfortable” with the board and management?

description: We present a detailed spectroscopic analysis of the luminous blue variable AG Carinae during the last two visual minimum phases of its S-Dor cycle (1985-1990 and 2000-2003). The analysis reveals an overabundance of He, N, and Na, and a depletion of H, C, and O, on the surface of AG Car, indicating the presence of CNO-processed material. Furthermore, the ratio N/O is higher on the stellar surface than in the nebula. We found that the minimum phases of AG Car are not equal to each other, since we derived a noticeable difference between the maximum effective temperature achieved during 1985-1990 (22,800 K) and 2000-2001 (17,000 K). While the wind terminal velocity was 300 km/s in 1985-1990, it was as low as 105 km/s in 2001. The mass-loss rate, however, was lower from 1985-1990 (1.5 x 10^(-5) Msun/yr) than from 2000-2001 (3.7 x 10^(-5) Msun/yr). We found that the wind of AG Car is significantly clumped (f=0.10 - 0.25) and that clumps must be formed deep in the wind. We derived a bolometric luminosity of 1.5 x 10^6 Lsun during both minimum phases which, contrary to the common assumption, decreases to 1.0 x 10^6 Lsun as the star moves towards maximum flux in the V band. Assuming that the decrease in the bolometric luminosity of AG Car is due to the energy used to expand the outer layers of the star (Lamers 1995), we found that the expanding layers contain roughly 0.6 - 2 Msun. Such an amount of mass is an order of magnitude lower than the nebular mass around AG Car, but is comparable to the nebular mass found around lower-luminosity LBVs and to that of the Little Homunculus of Eta Car. If such a large amount of mass is indeed involved in the S Dor-type variability, we speculate that such instability could be a failed Giant Eruption, with several solar masses never becoming unbound from the star.(abridged)

description: This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.

description: The five dimensional Brans-Dicke theory naturally provides two scalar fields by the Killing reduction mechanism. These two scalar fields could account for the accelerated expansion of the universe. We test this model and constrain its parameter by using the type Ia supernova (SN Ia) data. We find that the best fit value of the 5-dimensional Brans-Dicke coupling contant is $ω= -1.9$. This result is also consistent with other observations such as the baryon acoustic oscillation (BAO).

description: The compact linear collider (CLIC) requires a crab cavity to align bunches prior to collision. The bunch structure demands tight amplitude and phase tolerances of the RF fields inside the cavity, for the minimal luminosity loss. Beam loading effects require special attention as it is one potential sources of field errors in the cavity. In order to assist the amplitude and phase control, we propose a travelling wave (TW) structure with a high group velocity allowing rapid propagation of errors out of the system. Such a design makes the cavity structure significantly different from previous ones. This paper will look at the implications of this on other cavity parameters and the optimisation of the cavity geometry.

Community television as an aid for citizen involvement in the planning process

description: An increasing desire on the part of the public to have more control over the environment in which they live is raising demands for a more decentralized decision-making structure. These demands mean a change in the power structure. Information has become the source of power and control. If citizens are to be involved equally in decisions, it means they must have freer access to the reception and distribution of information - especially in the mass media. Television as a medium has the capacity to deeply involve people and to transmit a large volume of information. In Canada, the content of broadcast television is controlled by the government agency, the CBC, and private broadcasters. Financial interests (advertisers and stockholders) can exert strong influence on programme content. A scarcity of broadcast channels and very expensive and complicated equipment restrict access to broadcast television. Cable television offers a solution. It has a potential capacity of eighty-two channels; it does not require as sophisticated equipment; and the Canadian Radio-Television Commission requires the cable system operator to provide a community channel. Free access by citizens to a cable channel for expression and information is the basis of community television. Several cases, in which media access and citizen influence over decisions were improved, were examined. The Fogo Island project exhibited the power of film to help a community to formulate its goals and define solutions to its problems. The Drumheller project used video-tape, instead of film, to the same ends. In both these projects the citizens controlled the content of the "programmes". The Barrie experiment used two electronic media (television and telephone) for dialogue. The content of the programme was determined by a community committee. The Richmond project used electronic dialogue but the content was greatly influenced by a technical panel. The experiment in the West End was designed to spur discussion of the future of that area, to interest some residents in the use of video and cable television for expression of their attitudes about West End life and some directions for development. On a small scale the experiment was successful; the extension over a longer period of time will determine its final outcome.
