description: This is a scanned copy of a document on a line intercept in Helderfontein / Grootberg, Grootvadersbosch, Langeberg, site 3320DD/2. The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities in state plantations would affect climate, water conservation and erosion, and was later expanded to include studies of fynbos ecology, fire and alien species. Studies from the 1930s to the early 1990s saw the accumulation of a large amount of data dealing with fire experiments, detailed vegetation plot surveys, rare plant surveys and ecological studies, hydrological studies and the development of management plans for catchments around the Western Cape. SAEON now houses the archive of data collected by the Jonkershoek Forestry Research Center, which was originally held by the Council for Scientific and Industrial Research (CSIR).

description: AbstractObjectivesFuzzy trace theory was used to examine the effect of information concerning medication benefits and side-effects on willingness to use a hypothetical medication.MethodsParticipants (N=999) were recruited via Amazon Mechanical Turk. Using 3×5 experimental research design, each participant viewed information about medication side effects in 1 of 3 formats and information about medication benefits in 1 of 5 formats. For both side-effects and benefits, one format presented only non-numeric information and the remaining formats presented numeric information.ResultsIndividuals in the non-numeric side-effect condition were less likely to take the medication than those in the numeric conditions (pConclusionsOur findings suggest that non-numeric side-effect information conveys the gist that the medication can cause harm, decreasing willingness to use the medication; whereas non-numeric benefit information has the opposite effect.Practice implicationsPresenting side-effect and benefit information in non-numeric format appears to bias decision-making in opposite directions. Providing numeric information for both benefits and side-effects may enhance decision-making. However, providing numeric benefit information may decrease adherence, creating ethical dilemmas for providers.

description: Gamification has been applied in software engineering to improve quality and results by increasing people's motivation and engagement. A systematic mapping has identified research gaps in the field, one of them being the difficulty of creating an integrated gamified environment comprising all the tools of an organization, since most existing gamified tools are custom developments or prototypes. In this paper, we propose a gamification software architecture that allows us to transform the work environment of a software organization into an integrated gamified environment, i.e., the organization can maintain its tools, and the rewards obtained by the users for their actions in different tools will mount up. We developed a gamification engine based on our proposal, and we carried out a case study in which we applied it in a real software development company. The case study shows that the gamification engine has allowed the company to create a gamified workplace by integrating custom developed tools and off-the-shelf tools such as Redmine, TestLink, or JUnit, with the gamification engine. Two main advantages can be highlighted: (i) our solution allows the organization to maintain its current tools, and (ii) the rewards for actions in any tool accumulate in a centralized gamified environment.

title: The development of a field-portable MEMS gravimeter

Subjects: subject: Gravimetry, low noise, electronics, miniaturisation, field test.

description: Gravimetry is a technique that has existed since the 17th and 18th century and involves the measurement of the acceleration due to gravity. The technique can be used to measure changes in density below the ground where conventional methods cannot. This is because gravity cannot be shielded, and therefore, can always be measured. It has many useful applications, particularly in surveying for oil, gas and minerals but can also be used to detect the precursors to volcanic eruptions and earthquakes, the density contrast of buried walls for archaeology and the detection of subsurface voids. Typically, however, gravimeters can cost in excess of ￡70k and weight over 8 kg. This cost and weight has prohibited some applications of gravimeters where either many of the devices would be required or if weight was prohibitive. In the winter of 2014, an important step forward to a lightweight, low-cost and portable MEMS gravimeter was made. This was the first time that a MEMS based gravimeter had measured the Earth Tides as reported by R. P. Middlemiss et al. The device, however, still required a large array of electronics and vacuum equipment which made it impossible to be able to be taken into the field. Clearly, if the device was to ever become a disruptive technology within the gravimeter industry, significant effort would be required to obtain a device with sufficient sensitivity that was also portable. This thesis highlights the work that was required to bring the MEMS that was a lab-bound device, and make successful measurements of the change in acceleration due to gravity in the field. In this thesis, a miniaturised MEMS gravimeter is presented with an RMS of 13 μGal when averaged to 1000 s, a factor three better than the original set-up from R. P. Middlemiss et al. The system went from a set-up with the approximate dimensions of a typical fridge freezer(including the array of electronic equipment) to a portable platform of dimensions 30cm wide by 30 cm deep by 15 cm high. The platform used a small steel cube as a vacuum container for the device, three micrometer legs for precision levelling, batteries and a custom electronics board. This custom electronics board was designed, tested and improved during the course of this thesis. The board was controlled by a microcontroller from Microchip (the dsPIC33EP512MU810) and is shown to be capable of a large amount of digital filtering that was required for this application, including the use of a decimator and digital based lock-in amplifier. The board measured displacements, temperatures (which were also controlled) and tilts, all of which the microcontroller digitally filtered and down sampled so that they could be sent to a computer for data logging.

description: We present a financial market model, characterized by self-organized criticality, that is able to generate endogenously a realistic price dynamics and to reproduce well-known stylized facts. We consider a community of heterogeneous traders, composed by chartists and fundamentalists, and focus on the role of informative pressure on market participants, showing how the spreading of information, based on a realistic imitative behavior, drives contagion and causes market fragility. In this model imitation is not intended as a change in the agent's group of origin, but is referred only to the price formation process. We introduce in the community also a variable number of random traders in order to study their possible beneficial role in stabilizing the market, as found in other studies. Finally we also suggest some counterintuitive policy strategies able to dampen fluctuations by means of a partial reduction of information.

description: To achieve successful and durable bituminous waterproof membranes the designer must consider the properties and behaviour of both bitumen and reinforcement, the nature and behaviour of the surface to which it is applied, and the conditions of exposure or properties of the environment in which it must serve. The composite membrane has certain desirable properties, but is subject to several mechanisms of deterioration that can be allowed for or guarded against by design. The protection or shading of a membrane from solar radiation (CBD 65) has great value in extending its life, as does provision for drainage and the avoidance of trapped moisture. In some cases the occurrence of membrane failure can be prevented by a planned program of periodic maintenance. The manner of installation and quality of workmanship, however, are of fundamental importance to the performance of bituminous membranes.

description: We consider generic rotating axially symmetric "dirty" (surrounded by matter) black holes. Near-horizon circular equatorial orbits are examined in two different cases of near-extremal (small surface gravity $κ$) and exactly extremal black holes. This has a number of qualitative distinctions. In the first case, it is shown that such orbits can lie as close to the horizon as one wishes on suitably chosen slices of space-time when $κ\rightarrow 0$. This generalizes observation of T.\ Jacobson Class. Quantum Grav. 28 187001 (2011) made for the Kerr metric. If a black hole is extremal ($κ=0$), circular on-horizon orbits are impossible for massive particles but, in general, are possible in its vicinity. The corresponding black hole parameters determine also the rate with which a fine-tuned particle on the noncircular near-horizon orbit asymptotically approaches the horizon. Properties of orbits under discussion are also related to the Ba% ñados-Silk-West effect of high energy collisions near black holes. Impossibility of the on-horizon orbits in question is manifestation of kinematic censorship that forbids infinite energies in collisions.

Successful $N_2$ leptogenesis with flavour coupling effects in realistic unified models

Year: 2015
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In realistic unified models involving an $SO(10)$-like pattern of Dirac and heavy right-handed (RH) neutrino masses, the lightest right-handed neutrino $N_1$ is too light to yield successful thermal leptogenesis, barring highly fine tuned solutions, while the second heaviest right-handed neutrino $N_2$ is typically in the correct mass range. We show that flavour coupling effects in the Boltzmann equations may be crucial to the success of such $N_2$ dominated leptogenesis, by helping to ensure that the flavour asymmetries produced at the $N_2$ scale survive $N_1$ washout. To illustrate these effects we focus on $N_2$ dominated leptogenesis in an existing model, the A to Z of flavour with Pati-Salam, where the neutrino Dirac mass matrix may be equal to an up-type quark mass matrix and has a particular constrained structure. The numerical results, supported by analytical insight, show that in order to achieve successful $N_2$ leptogenesis, consistent with neutrino phenomenology, requires a "flavour swap scenario" together with a less hierarchical pattern of RH neutrino masses than naively expected, at the expense of some mild fine-tuning. These results may be relevant for other $SO(10)$-like unified models where $N_2$ leptogenesis is necessary.

We perform a numerical calculation of the kink-kink scattering in one of the considered variants of the $φ^8$ model, and find the critical collision velocity $v_{\scriptsize \mbox{cr}}$ that separates the different collision regimes: inelastic bounce of the kinks at $v_{\scriptsize \mbox{in}}\ge v_{\scriptsize \mbox{cr}}$, and capture at $v_{\scriptsize \mbox{in}}

description: The outstanding progress in nanostructure fabrication and cooling technologies allows what was unthinkable a few decades ago: bringing single-mode mechanical vibrations to the quantum regime. The coupling between photon and phonon excitations is a natural source of nonclassical states of light and mechanical vibrations, and its study within the field of cavity optomechanics is developing lightning-fast. Photonic crystal cavities are highly integrable architectures that have demonstrated the strongest optomechanical coupling to date, and should therefore play a central role for such hybrid quantum state engineering. In this context, we propose a realistic heralding protocol for the on-chip preparation of remotely entangled mechanical states, relying on the state-of-the-art optomechanical parameters of a silicon-based nanobeam structure. Pulsed sideband excitation of a Stokes process, combined with single photon detection, allows writing a delocalised mechanical Bell state in the system, signatures of which can then be read out in the optical field. A measure of entanglement in this protocol is provided by the visibility of a characteristic quantum interference pattern in the emitted light.

description: The propagation of filaments in the Scrape Off Layer (SOL) of tokamaks largely determine the plasma profiles in the region. In a conduction limited SOL, parallel temperature gradients are expected, such that the resistance to parallel currents is greater at the target than further upstream. Since the perpendicular motion of an isolated filament is largely determined by balance of currents that flow through it, this may be expected to affect filament transport. 3D simulations have thus been used to study the influence of enhanced parallel resistivity on the dynamics of filaments. Filaments with the smallest perpendicular length scales, which were inertially limited at low resistivity (meaning that polarization rather than parallel currents determine their radial velocities), were unaffected by resistivity. For larger filaments, faster velocities were produced at higher resistivities, due to two mechanisms. Firstly parallel currents were reduced and polarization currents were enhanced, meaning that the inertial regime extended to larger filaments, and secondly a potential difference formed along the parallel direction so that higher potentials were produced in the region of the filament for the same amount of current to flow into the sheath. These results indicate that broader SOL profiles could be produced at higher resistivities.

Shale geochemistry as a proxy for shear strength

Publisher: name: Macquarie University
Year: 2023
Subjects: Other education not elsewhere classified

description: Australian iron ore is mined across the Hamersley Province, Western Australia, from open pit mines composed of mineralised interlayered strong Banded Iron Formations (BIFs) and weaker shales. Mine wall failures most commonly occur in weaker shale units with low shear strengths. However, the principal controls on shale shear strength are poorly constrained. This study shows that shale geochemistry, particularly alumina content, is a good proxy for shear strength. The metasomatism that enriched iron in the BIFs has variably strengthened or weakened the interbedded shales. This study finds alumina, silica, and iron oxide (III) to be the dominant element oxides in the shales, where shales with an alumina content <10 wt% Al2O3 N are likely to be strong and those >16% wt% Al2O3 N are likely to be weak. The alumina content of the shales better correlates with shear strength than with defect surface conditions, previously thought to be the controlling factor on strength. This research permits shale shear strength to be estimated in a field environment by using a portable Xray fluorescence analyser to determine the alumina content, helping to narrow the selection of shale samples in need of direct shear testing.

description: Adjuvant endocrine therapy (ET) can reduce the risk of recurrence among females with hormone receptor-positive breast cancer. Overall, initiation and adherence to ET are suboptimal, though reasons are not well described. The study's objective was to better understand ET decision making, prescribing, and patient management from oncology providers' perspectives. Using purposive sampling, we recruited oncology providers who saw five or more breast cancer patients per week (n=20). We conducted 30-45-minute telephone interviews, using a semistructured guide to elicit perspectives on ET use. We used thematic content analysis to systematically identify categories of meaning and double-coded transcripts using Atlas.ti. Providers recommend ET to all eligible patients except those with contraindications or other risk factors. Providers base their ET prescribing decisions on the patient's menopausal status, side effects, and comorbidities. ET is typically discussed multiple times: at the onset of breast cancer treatment and in more detail after other treatment completion. Providers felt that the associated recurrence risk reduction is the most compelling argument for patients during ET decision making. While providers rarely perceived noninitiation as a problem, nonadherence was prevalent, often due to unresolvable side effects. From the clinicians' perspectives, side effects from ET are the dominant factor in nonadherence. Efforts to improve adherence should focus on strategies to minimize side effects and ensure clinicians and patients are well informed regarding optimal side effect management. This finding has important implications for novel endocrine regimens that offer improved outcomes through longer duration or more intensive therapy.

description: The LHCb has discovered two new states with preferred $J^P$ quantum numbers $3/2^-$ and $5/2^+$ from $Λ_b$ decays. These new states can be interpreted as hidden charm pentaquarks. It has been argued that the main features of these pentaquarks can be described by diquark model. The diquark model predicts that the $3/2^-$ and $5/2^+$ are in two separate octet multiplets of flavor $SU(3)$ and there is also an additional decuplet pentaquark multiplet. Finding the states in these multiplets can provide crucial evidence for this model. The weak decays of b-baryon to a light meson and a pentaquark can have Cabibbo allowed and suppressed decay channels. We find that in the $SU(3)$ limit, for $U$-spin related decay modes the ratio of the decay rates of Cabibbo suppressed to Cabibbo allowed decay channels is given by $|V_{cd}|^2/|V_{cs}|^2$. There are also other testable relations for b-baryon weak decays into a pentaquark and a light pseudoscalar. These relations can be used as tests for the diquark model for pentaquark.

Water has been identified as a critical resource for development of robust cis-lunar infrastructure. Providing a potential source of clean-energy propellant and/or an essential consumable for humans or agriculture on crewed trips to the Moon or Mars while avoiding high costs of launching from Earth is thus a highly desirable element to cis-lunar infrastructure.

The OSIRIS-REx mission provided a complete survey of the asteroid Bennu and will return regolith samples to Earth in 2023, making this a well-understood and low-risk target that is estimated to be on average 6.3% water by mass. The Khepri Project comprises a team of international students, academics, and industry subject matter experts working on the technical design, business case, and political aspects of a feasibility study to mine asteroid Bennu for water.

This study included outlining a multi-year mining mission, where robotic explorers would be sent to both an orbit around Bennu as well as to Bennu’s surface, culminating in tonnes of water extracted for transport back to cis-lunar space for immediate use. Mining asteroid Bennu is an unprecedented scientific opportunity to study the formation of our solar system - large scale operations could enable kilogram scale samples across Bennu’s surface and subsurface.

Such an endeavor would provide new opportunities for synergy with other industries, such as Canada’s well established mining sector. Future mining of near-earth asteroids provides additional resources (e.g. rare earth elements) to support Canada’s manufacturing sector as well. Pursuing such a mission provides an opportunity to demonstrate novel surface operations on small bodies leading to future asteroid mining endeavors. These include: use of autonomous robotic elements; improved in-situ resource utilization (ISRU) technologies; and deep space rendezvous. The Canadian Space Agency’s leadership in this direction would engage Canadian academia, industry, and students, and would facilitate continued development of highly qualified personnel in planetary geology and space robotics & operations.

This document outlines the various elements considered in this feasibility study, culminating in mission and system design.

description: We present a design and characterization of optically transparent electrodes suitable for atomic and molecular physics experiments where high optical access is required. The electrodes can be operated in air at standard atmospheric pressure and do not suffer electrical breakdown even for electric fields far exceeding the dielectric breakdown of air. This is achieved by putting an ITO coated dielectric substrate inside a stack of dielectric substrates, which prevents ion avalanche resulting from Townsend discharge. With this design, we observe no arcing for fields of up to 120 kV/cm. Using these plates, we directly verify the production of electric fields up to 18~kV/cm inside a quartz vacuum cell by a spectroscopic measurement of the dc Stark shift of the $5^2S_{1/2} \rightarrow 5^2P_{3/2}$ transition for a cloud of laser cooled Rubidium atoms. We also report on the shielding of the electric field and residual electric fields that persist within the vacuum cell once the electrodes are discharged. In addition, we discuss observed atom loss that results from the motion of free charges within the vacuum. The observed asymmetry of these phenomena on the bias of the electrodes suggests that field emission of electrons within the vacuum is primarily responsible for these effects and may indicate a way of mitigating them.

description: BackgroundStudies in chronic noncancer pain settings have found that opioid use increases health care utilization. Despite the key role of analgesics, specifically opioids, in the setting of cancer pain, there is no literature to our knowledge about the relationship between adherence to prescribed around-the-clock (ATC) analgesics and acute health care utilization (hospitalization) among patients with cancer pain.PurposeTo identify adherence patterns over time for cancer patients taking ATC analgesics for pain, cluster these patterns into adherence types, combine the types into an adherence risk factor for hospitalization, identify other risk factors for hospitalization, and identify risk factors for inconsistent analgesic adherence.Materials and methodsData from a 3-month prospective observational study of patients diagnosed with solid tumors or multiple myeloma, having cancer-related pain, and having at least one prescription of oral ATC analgesics were collected. Adherence data were collected electronically using the medication event-monitoring system. Analyses were conducted using adaptive modeling methods based on heuristic search through alternative models controlled by likelihood cross-validation scores.ResultsSix adherence types were identified and combined into the risk factor for hospitalization of inconsistent versus consistent adherence over time. Twenty other individually significant risk factors for hospitalization were identified, but inconsistent analgesic adherence was the strongest of these predictors (ie, generating the largest likelihood cross-validation score). These risk factors were adaptively combined into a model for hospitalization based on six pairwise interaction risk factors with exceptional discrimination (ie, area under the receiver-operating-characteristic curve of 0.91). Patients had from zero to five of these risk factors, with an odds ratio of 5.44 (95% confidence interval 3.09–9.58) for hospitalization, with a unit increase in the number of such risk factors.ConclusionInconsistent adherence to prescribed ATC analgesics, specifically the interaction of strong opioids and inconsistent adherence, is a strong risk factor for hospitalization among cancer outpatients with pain.

description: In this paper, we consider the almost periodic dynamics of a multispecies Lotka-Volterra mutualism system with time varying delays on time scales. By establishing some dynamic inequalities on time scales, a permanence result for the model is obtained. Furthermore, by means of the almost periodic functional hull theory on time scales and Lyapunov functional, some criteria are obtained for the existence, uniqueness and global attractivity of almost periodic solutions of the model. Our results complement and extend some scientific work in recent years. Finally, an example is given to illustrate the main results.

description: The information-motivation-behavioral skills (IMB) model has been used to explain and promote medication adherence among patients with diabetes and HIV. The objective of this study was to examine whether the IMB model predicted medication adherence among vasculitis patients. Adult vasculitis patients (n=228) completed online questionnaires at baseline and 3-month follow-up. Linear regressions were calculated to determine the direct effects of information and motivation on medication adherence (P<0.05). A mediation analysis using a bootstrapping approach was used to test whether behavioral skills significantly mediated the effect of information and motivation on medication adherence. Participants reported high levels of information (M=4.0; standard deviation [SD]=0.68), moderate levels of motivation (M=2.7; SD=1.00), and high levels of behavioral skills (M=4.1; SD=0.74). In the regression model, only behavioral skills (B=0.38; P<0.001) were significantly associated with medication adherence; however, mediation analysis revealed that behavioral skills significantly mediated the effects of information and motivation on medication adherence. The results support the IMB-hypothesized relationships between information, motivation, behavioral skills, and medication adherence in our sample. Findings suggest that providers should work with vasculitis patients to increase their medication-related skills to improve medication adherence.
