description: We present follow-up observations of 97 point sources from the Wilkinson Microwave Anisotropy Probe (WMAP) 3-year data, contained within the New Extragalactic WMAP Point Source (NEWPS) catalogue between declinations of -4 and +60 degrees; the sources form a flux-density-limited sample complete to 1.1 Jy (approximately 5 sigma) at 33 GHz. Our observations were made at 16 GHz using the Arcminute Microkelvin Imager (AMI) and at 33 GHz with the Very Small Array (VSA). 94 of the sources have reliable, simultaneous -- typically a few minutes apart -- observations with both telescopes. The spectra between 13.9 and 33.75 GHz are very different from those of bright sources at low frequency: 44 per cent have rising spectra (alpha < 0.0), where flux density is proportional to frequency^-alpha, and 93 per cent have spectra with alpha < 0.5; the median spectral index is 0.04. For the brighter sources, the agreement between VSA and WMAP 33-GHz flux densities averaged over sources is very good. However, for the fainter sources, the VSA tends to measure lower values for the flux densities than WMAP. We suggest that the main cause of this effect is Eddington bias arising from variability.

description: Proper sizing of harvest equipment has concerned farmers and lenders since advent of mechanized agriculture. Under-equipped farming operations may not be able to harvest crops without yield and/or quality penalties. Over-equipped farming operations expose themselves to unnecessary expenses. Uncertainty of weather conducive for field operations further complicates the decision- making process. The overall objective of this research was to estimate the machinery investment necessary to complete wheat harvest operations under a range of harvest-time weather risk, specifically for uncertainty of the number of good days suitable to conduct fieldwork (DSFW). We evaluate a range of weather probabilities for the nine USDA crop-reporting districts in Kansas to determine the winter wheat acreage that a single combine can harvest. Weather probabilities estimated from 33 years of observed weekly DSFW were analyzed to determine the expected number of days available to harvest wheat in Kansas. Results indicate that during bad weather years (20th percentile DSFW probability), 15% to 26% of acreage must be harvested outside the typical harvest dates leading to increased likelihood of reduced yield, harvest loss, and adverse quality impacts. Although a 30th percentile weather year was sufficient in at least one location, a 15th percentile weather year encouraged most farm decision makers to invest in additional harvesting capacity. Our conclusions are of interest to not only Kansas farmers but to farmers, agricultural lenders, equipment manufacturers, and sales forces across the wheat belt.

description: Traffic volume data collection is a crucial aspect of transportation engineering and urban planning, as it provides vital insights into traffic patterns, congestion, and infrastructure efficiency. Traditional manual methods of traffic data collection are both time-consuming and costly. However, the emergence of modern technologies, particularly Light Detection and Ranging (LiDAR), has revolutionized the process by enabling efficient and accurate data collection. Despite the benefits of using LiDAR for traffic data collection, previous studies have identified two major limitations that have impeded its widespread adoption. These are the need for multiple LiDAR systems to obtain complete point cloud information of objects of interest, as well as the labor-intensive process of annotating 3D bounding boxes for object detection tasks. In response to these challenges, the current study proposes an innovative framework that alleviates the need for multiple LiDAR systems and simplifies the laborious 3D annotation process. To achieve this goal, the study employed a single LiDAR system, that aims at reducing the data acquisition cost and addressed its accompanying limitation of missing point cloud information by developing a Point Cloud Completion (PCC) framework to fill in missing point cloud information using point density. Furthermore, we also used zero-shot learning techniques to detect vehicles and pedestrians, as well as proposed a unique framework for extracting low to high features from the object of interest, such as height, acceleration, and speed. Using the 2D bounding box detection and extracted height information, this study is able to generate 3D bounding boxes automatically without human intervention.

description: By means of a maximum entropy joint cost allocation model with farm-specific allocation factors that account for economies of scale, full costs of 198 milk producers in the Swiss plain region are calculated. The effect of farm-specific allocation factors is found to be small; nevertheless it contributes to a more precise joint cost allocation to the enterprises of a farm. Average milk costs are CHF 1.31/kg â€“ twice as high as producer milk price â€“ and differ substantially between farms. In a regression analysis, the herd size and the milk yield per cow turned out to be the major cost-cutting factors.

description: We entertain the idea that a suitable background of cold (very low momentum) pseudoscalar particles or condensate, may trigger a background that effectively generates Lorentz-invariance violation. This aether-like background induces a Chern-Simons modification of QED. Physics is different in different frames and, in the rest frame of the pseudoscalar background, high momentum photons can decay into pairs. The threshold for such decay depends quadratically on the rest mass of the particles. This mechanism could explain in a natural way why antiprotons are absent in recent cosmic ray measurements. A similar signal could be used as a probe of pseudoscalar condensation in heavy ion collisions.

Feasibility study of computer-based auditing : an empirical approach
Creators: name: Wu, Peter King Sai
Publisher: name: University of British Columbia

description: The changing accounting environment and the innovation of computer technology have altered audit techniques. Currently, more than thirty packages are used by auditors. In view of the similarities, the "Audit Command Language" (ACL), aimed at combining and extending the features of present packages, was developed. The M.B.A. thesis research presented here focuses on a feasibility study of auditing with audit package systems and on the implications for ACL. An empirical approach was used and sets of questionnaires were distributed to three hundred and one firms of various sizes and industries throughout Canada and the United States of America. The thesis presents a discussion of the costs that should be considered and the benefits that could be gained from the use of audit packages (AP's). Other benefits are discussed as well. It can be concluded from the study that there are many advantages in the adoption of the systems. AP's are more efficient than other techniques in auditing EDP records. It is desirable and feasible to develop ACL provided that the actual cost of developing and implementing it does not exceed the expected benefits and returns. The optimum cost of ACL cannot be determined here because the average cost of developing a similar package cannot be determined from this study due to insufficient data. Finally, some practical problems may be encountered. Nonetheless, these are solvable in one way or another. In conclusion, it should be feasible to develop ACL as the professional audit command language of the future.

description: F-theory is one of frameworks in string theory where supersymmetric grand unification is accommodated, and all the Yukawa couplings and Majorana masses of right-handed neutrinos are generated. Yukawa couplings of charged fermions are generated at codimension-3 singularities, and a contribution from a given singularity point is known to be approximately rank 1. Thus, the approximate rank of Yukawa matrices in low-energy effective theory of generic F-theory compactifications are minimum of either the number of generations N_gen = 3 or the number of singularity points of certain types. If there is a geometry with only one E_6 type point and one D_6 type point over the entire 7-brane for SU(5) gauge fields, F-theory compactified on such a geometry would reproduce approximately rank-1 Yukawa matrices in the real world. We found, however, that there is no such geometry. Thus, it is a problem how to generate hierarchical Yukawa eigenvalues in F-theory compactifications. A solution in the literature so far is to take an appropriate factorization limit. In this article, we propose an alternative solution to the hierarchical structure problem (which requires to tune some parameters) by studying how zero mode wavefunctions depend on complex structure moduli. In this solution, the N_gen x N_gen CKM matrix is predicted to have only N_gen entries of order unity without an extra tuning of parameters, and the lepton flavor anarchy is predicted for the lepton mixing matrix. We also obtained a precise description of zero mode wavefunctions near the E_6 type singularity points, where the up-type Yukawa couplings are generated.

description: The study aims to present an analysis of a clinical case of severe exacerbation of multiple sclerosis with a late gestation period in a patient with high disease activity, to assess the possibility of choosing modern methods of treating the disease, taking into account the effectiveness for the mother and the risk for the child. Material and methods. A clinical case of multiple sclerosis is presented: the anamnesis of the disease, the dynamics of symptoms during exacerbation and in its outcome, the therapeutic difficulties of managing the patient during pregnancy and the possibility of controlling the activity of the disease before and during pregnancy as well as after labor are analyzed. Results. Pulse therapy with methyl-prednisone at a dose of 1 000 mg daily, then every other day, in the amount of 7 infusions, followed by intravenous immunoglobulin, allowed to stop a severe exacerbation in a patient with a pregnancy of 34+3 weeks, with a highly active flow of multiple sclerosis, without a response to the drugs used. There were no side effects of treatment at the time of discharge from the hospital. No complications that could be attributed to the side effects of steroid treatment were found in the catamnesis of the mother and the newborn. The worsening of the neurological deficit occurred three months after labor.

description: Methods are available to predict nitrogen needs of winter wheat based on plant sensing, but adoption rates by producers are low. Low adoption rates are likely due to economic feasibility. The objective of this paper was to develop a method to Bayesian update prior information about nitrogen application with precision sensing information and determine if Bayesian updated nitrogen recommendations increase the economic feasibility of precision sensing technology. Results indicated that Bayesian updated nitrogen recommendations were higher than precision sensing recommendations. However, the Bayesian nitrogen recommendations did not increase net returns.

description: Previous research on agricultural innovation has focused on the role farm-level characteristics play in the rate of adoption. While existing studies have accounted for the effects of farm level characteristics such as gross sales and experience on adoption, recent research has begun to examine the role that other resources play in the adoption decision. The objective of this study is to examine the role that social capital, knowledge networks, and other structural and demographic factors play in the development of a firmâ€™s absorptive capacity in prairie agricultural system. Using a survey of producers in Saskatchewan, Alberta, and Manitoba, I develop two regression models of absorptive capacity. The results from this study indicate that the ability to assimilate and integrate information on products and processes depends on a producerâ€™s utilization of supplier and professional networks, as well as the number of days attending workshops and conferences. The paper concludes with a discussion of various ways farmers can build their absorptive capacity.

description: Based on measurements with the Effelsberg 100-m telescope, a multi-line study of molecular species is presented toward the gravitational lens system PKS1830-211. Obtaining average radial velocities and performing Large Velocity Gradient radiative transfer calculations, the aims of this study are (1) to determine the density of the gas, (2) to constrain the temperature of the cosmic microwave background, and (3) to evaluate the proton-to-electron mass ratio at redshift 0.9. Analyzing data from six rotational HC3N transitions (this includes the J=7-6 line, which is likely detected for the first time in the interstellar medium) we obtain about 2000 cm-3 for the gas density of the south-western absorption component. Again toward the south-western source, excitation temperatures of molecular species with optically thin lines and higher rotational constants are, on average, consistent with the expected temperature of the cosmic microwave background, T_CMB = 5.14 K. However, individually, there is a surprisingly large scatter which far surpasses expected uncertainties. A comparison of CS J=1-0 and 4-3 optical depths toward the weaker north-western absorption component results in an excitation temperature of 11 K and a 1-sigma error of 3 K. For the south-eastern main component, a comparison of velocities determined from ten optically thin NH3 inversion lines with those from five optically thin rotational transitions of HC3N, observed at similar frequencies, constrains potential variations of the proton-to-electron mass ratio, with respect to its present value, to <1.4 x 10^-6 with 3-sigma confidence. Also including optically thin rotational lines from other molecular species, it is emphasized that systematic errors are smaller than 1 km/s, corresponding to an uncertainty of 10-6.

description: Trade structure and pattern of Lesothoâ€™s wool and mohair sub-sector were analyzed using 4 digits Standard International Trade Classification (SITC) of wool and Mohair and different trade indicators from 2003-2012. Revealed Comparative Advantage (RCA), Hirschman Index (HI), Effective Rate of Protection (ERP) and Nominal Rate of Protection (NRP) were calculated. Trade map was also used to assess the diversification of wool and mohair markets. The study revealed that Lesotho have a Revealed Comparative Advantage (RCA) of wool and mohair sub-sector from 2003 to 2012. Hirschman Index (HI) indicated that wool and mohair sub-sectors shows low concentration from 2003 to 2012. Lower concentration reduces the impact of international trade risk due to the possibility of price fluctuation of wool and mohair products. ERP and NRP were also calculated, using an enterprise budget of Lesotho for wool and mohair production. The result shows that the ERP and NRP shows negative which indicate that the weighted input tariffs on wool and mohair inputs amount are more than the output tariffs, this implies that the sub-sector is taxed by the government tariff policies. The NRP is higher than the ERP; this implies that tariff applied on the output is higher than the tariff applied on the inputs. The results from the trade map indicated that Lesothoâ€™s wool and mohair have high degree of concentration in China and South Africa. The structure of the tariff schedule may have an important bearing on efficiency. Thus, the study recommended that the tariff structure of the input sector for wool and mohair should be reinvestigated and Lesotho should be diversifying its market of wool and mohair.

Low-frequency modes of variability of the Indian Ocean and their connection with the Indian Ocean Dipole
Creators: name: Sakova, IV
Publisher: name: University Of Tasmania
Year: 2023

description: The thesis investigates the low-frequency variability of the Indian Ocean, based on a number of independent observational and reanalysis data sets. These data sets include altimetry sea level anomaly (SLA) gridded field, subsurface temperature from selected Expendable Bathythermograph (XBT) lines, NOAA Optimum Interpolation Sea Surface Temperature (SST) and Extended SST V2 (Kaplan) data sets, tide gauge and reconstructed sea level data, surface winds from National Center for Environmental Prediction (NCEP) and Dipole Mode Indexes from HadISST, as well as coral core records used as a long term proxy climate signal. The analysis is primarily based on identifying the major temporal scales by means of spectral analysis. It is found that in most regions of the Indian Ocean, the low-frequency variability (corresponding to periods of six months and longer) is concentrated in five spectral bands: semi-annual, annual, 18-20 months, 3 years, and 4 years and longer; at least during the last two decades. For each of the identified low-frequency variability modes, their spatial distributions as well as the temporal behaviour are investigated; the corresponding results are presented by means of spatial maps of power spectral density and movies. Despite the extensive literature on the variability of the Indian Ocean, to the best of our knowledge no systematic analysis of this kind has been conducted so far. While the existence of semi-annual and annual signals is well known, the presence of such a pronounced and well defined 18-month signal has not been previously identified. Its discovery is one of the main results of this study. Both the 18-month and 3-year signals are found to be directly related to the Indian Ocean Dipole (IOD) mode. The IOD events in the last two decades seem to predominantly occur as a result of their constructive interference. The connection established between these two quasi-periodic signals with the IOD allows us to suggest that the IOD phenomenon has oscillatory character. This suggestion opens up possibilities to improve the prediction of IOD, which is of a major importance for the seasonal weather prediction in Australia. In particular, it is shown that the status of the IOD in the last three years could be predicted two seasons ahead based on the estimate of the state of the 18-month signal.

description: In this study brand loyalty of pharmaceutical livestock products among commercial farmers was measured. The purpose of the study was to assist agribusinesses to identify the dominant determinant when commercial farmers purchase pharmaceutical livestock products from them. A structured questionnaire was used to employ an empirical study in a quantitative style to determine the commercial farmersâ€™ perceptions and buying behaviour when they buy pharmaceutical livestock products. The results indicated that the data were reliable. It also indicated that no practical significant differences existed between the four categories of pharmaceutical livestock products exist which means that these product categories could be managed similarly with regard to brand loyalty. All twelve the brand loyalty influences are regarded to be important. The influences Customer service, Brand performance and Brand trust are the three most important influences.

description: Abstract: Environmental degradation continues to be one of the greatest threats to human well-being, posing a disproportionate burden on communities of color. Environmental action, however, fails to reflect this urgency, leaving social-behavioral research at the frontier of environmental conservation, as well as environmental justice. Broad societal consensus for environmental action is particularly sparse among conservatives. The lack of even small personal sacrifices in favor of the environment could be attributed to the relatively low salience of environmental threats to white Americans and the partisan nature of environmentalism in America. We evaluate if (1) environmental action is causally related to the ideological value framing of an environmental issue; and (2) if the perceived race of impacted communities influences environmental action as a function of racial resentment. Using a large-scale, original survey experiment examining the case of air-pollution, we advance our understanding of environmental justice advocacy and environmental inaction in the United States.

description: We study the spectrum of the worldsheet theory of the bosonic closed string in the massless and extremal rotating BTZ black holes. We use a hyperbolic Wakimoto representation of the SL(2,R) currents to construct vertex operators for the string modes on these backgrounds. We argue that there are tachyons in the twisted sector, but these are not localised near the horizon. We study the relation to the null orbifold in the limit of vanishing cosmological constant. We also discuss the problem of extending this analysis to the supersymmetric case.

description: The probe of study is to examine and test Kaldorâ€™s first growth law insights on the inter-temporal causal relationship between agricultural sector growth and economic growth in Kenya. This study employs bounds testing approach to cointegration method known as ARDL (autoregressive distributed lag) and Granger causality test. The empirical results reveal agricultural growth is a causal effect to economic growth and also economic growth is a causal effect to agricultural growth, both in the long-run relationship. This is a comforting result for agricultural economists because it validates the standard policy recommendations aimed at stimulating growth and development through expansion of agriculture.

Predation interactions between zooplankton and two species of Chaoborus (Diptepa, Chaoboridae) in a small coastal lake
Creators: name: Fedorenko, Alice Y.R.
Publisher: name: University of British Columbia
Year: 2011

description: Feeding habits of two coexisting species of Chaoborus, C.trivittatus and C.americanus, were investigated in lake and in laboratory experiments, and by an extensive survey of larval crop contents. The field study showed that C.trivittatus has a two year life cycle, migrates dielly during the summer season down to 20 m, and is the more abundant of the two Chaoborus species. C.americanus has a one year life cycle and migrates at most over a distance of only 5 m. Seasonal abundance and distribution of most plankton types found in Eunice Lake were monitored during 1971 and 1972. Zooplankton had a low standing crop and were mostly found above 6 m. Zooplankton size and swimming velocity and size of larval head parts were measured in the laboratory and, together with the above data on vertical distribution, were used to evaluate the availability of zooplankton as prey for Chaoborus. The lake and laboratory experiments showed that rates of larval feeding and digestion increase significantly with temperature. Temperature, however, does not seem to affect feeding rate of the 4th instar C.trivittatus larvae. Feeding rates increase with larval age and vary with prey type and density. From analysis of chaoborid crop contents, diet differences were found among all instars of the two species, and these were related to prey size, abundance, and distribution. The calculated percent of prey standing crop that the Chaoborus in Eunice Lake could potentially remove ranged from a minimum of 3% for nauplii to a maximum of 20% for Diaptomus kenai. Seasonal changes in Choaborus instar composition and in zooplankton species composition result in reduced predation on any single zooplankton group. The observed diet of Chaoborus larvae in Eunice Lake was shown to be closely related to the morphology of Chaoborus and their prey and to the relative distribution of predator and prey.

description: When electrons are confined in two dimensions and subjected to strong magnetic fields, the Coulomb interactions between them become dominant and can lead to novel states of matter such as fractional quantum Hall liquids. In these liquids electrons linked to magnetic flux quanta form complex composite quasipartices, which are manifested in the quantization of the Hall conductivity as rational fractions of the conductance quantum. The recent experimental discovery of an anomalous integer quantum Hall effect in graphene has opened up a new avenue in the study of correlated 2D electronic systems, in which the interacting electron wavefunctions are those of massless chiral fermions. However, due to the prevailing disorder, graphene has thus far exhibited only weak signatures of correlated electron phenomena, despite concerted experimental efforts and intense theoretical interest. Here, we report the observation of the fractional quantum Hall effect in ultraclean suspended graphene, supporting the existence of strongly correlated electron states in the presence of a magnetic field. In addition, at low carrier density graphene becomes an insulator with an energy gap tunable by magnetic field. These newly discovered quantum states offer the opportunity to study a new state of matter of strongly correlated Dirac fermions in the presence of large magnetic fields.

description: The agricultural sector plays a key role on the rural development in South Africa. Open free trade market, creates a market were small-scale producers need to be able to compete against commercial producers. Therefore producers need to be more competitive to ensure that their farming enterprise is financially sustainable. Entrepreneurship may help producers exploit new opportunities so they can compete in an ever changing global market. There is no too little information regarding the ability of producers to be entrepreneurial in South Africa, therefore the aim it measure the levels of entrepreneurship among these producers. The case-study of the Eksteenskuil raisin producers was used to determine the levels of entrepreneurship and if there is a difference between commercial and smallholder producers. Smallholder and commercial producers did exhibited different levels of individual entrepreneurial competencies scores. There was a wide spread of scores among the distribution of the competencies which leaves room for improvement through education and training. It is recommended that future research in exploring the entrepreneurial competencies of producers and the effect thereof on the farming resources need to be considered. These farming resources can include efficient use of input allocation, market identification and financial performance of the farm.

Resource estimation and the Kunwarara magnesite deposit
Creators: name: Searston, SM
Publisher: name: University Of Tasmania
Year: 2023

description: The Kunwarara magnesite deposit, in Central Queensland was selected as a study site to evaluate the use of different resource calculation methodologies on tonnages and grades within the deposit. Initial appraisal consisted of classical statistics completed on 6 frequently analysed elements, magnesium, silica, manganese, iron, calcium and aluminium. Sample distribution was skewed, and indicative of mixed sample populations. This was attributed to a combination of factors, the most important being groundwater geochemistry in particular changes in pH. Samples were then split by lithology into sand, silt and clay fractions, and the statistics re-run. Again, the main factor controlling sample distribution was suggested to be groundwater geochemistry. Variography was completed for three dimensional and downhole orientations. Results showed that there were coherent ranges for magnesium, iron, aluminium, and manganese in the sand fraction. The silt lithology displayed better variograms from all elements, with only calcium returning unclear variogram ranges. In the silt fraction, iron and magnesium were not clear, while the remaining elements displayed clear ranges. A feature of all variograms was the \noise\" displayed. This was attributed to the mixed sample populations of each element and the sampling technique employed on the minesite. Five resource calculation techniques were tested: inverse distance squared and cubed ordinary kriging and indicator kriging on both composite and raw data. Tonnage and grade curves produced for each method indicated that there was relatively little difference between the methods in terms of tonnage or grade estimation. Generally the inverse distance cubed method produced the highest tonnages and grades while the indicator kriging (raw data) method returned the most conservative grades and tonnages. By evaluating the variance mean and median returned from each block model it was determined that indicator kriging was the most appropriate resource calculation method. Using the indicator kriging method on raw assay data a number of block sizes were evaluated. The 100 x 100 x 3 metre block size showed the minimum sample variance and is of sufficient size to allow for easy mine planning in a 3 million tonne per annum operation."

description: This work introduces a self and mutually exciting point process that embeds flexible residuals and intensity with discretely Markovian dynamics. By allowing the integration of diverse residual distributions, this model serves as an extension of the Hawkes process, facilitating intensity modeling. This model's nature enables a filtered historical simulation that more accurately incorporates the properties of the original time series. Furthermore, the process extends to multivariate models with manageable estimation and simulation implementations. We investigate the impact of a flexible residual distribution on the estimation of high-frequency financial data, comparing it with the Hawkes process.
