description: The inclusion of supersymmetric threshold corrections to the $b$-quark mass has dramatic consequences in scenarios with large CP-mixing effects in the Higgs sector. In particular, when the phase of the combination $M_{\tilde{g}}μ$ is $\sim 180^{\rm o} \pm 30^{\rm o}$, the lightest-sbottom squark becomes tachyonic and, possibly, the $b$-quark Yukawa coupling nonperturbative for values of $\tan β$ ranging from intermediate up to large or very large, depending on the size of $arg(A_tμ)$, $arg(A_bμ)$, and the details of the spectrum. For these scenarios, when allowed, as well as scenarios with different values of $arg(M_{\tilde{g}}μ)$, the cross sections for the production of the three neutral-Higgs bosons through $b$-quark have rather interesting dependences on $arg(A_tμ)$ and $arg(A_bμ)$, and the deviations induced by the $m_b$ corrections are rather large. In general, such production channel cannot be neglected with respect to the production through gluon fusion. For large CP-mixing effects, the lightest neutral-Higgs boson can be mainly CP odd and the $b$-quark fusion becomes its main production mechanism. Searches at the Tevatron and the LHC can easily detect such a Higgs boson, or constrain the CP-violating scenarios that allow it.

description: We study a problem concerning parabolic induction in certain p-adic unitary groups. More precisely, for $E/F$ a quadratic extension of p-adic fields the associated unitary group $G=\mathrm{U}(n,n)$ contains a parabolic subgroup $P$ with Levi component $L$ isomorphic to $\mathrm{GL}_n(E)$. Let $π$ be an irreducible supercuspidal representation of $L$ of depth zero. We use Hecke algebra methods to determine when the parabolically induced representation $ι_P^G π$ is reducible.

title: Visualisation and manipulation tools for Modal logic
Creators: name: Oliver, Martin John
Publisher: name: The Open University
Year: 1998

description: In this thesis, an investigation into how visualisation and manipulation tools can provide better support for learners of Modal logic is described. Problems associated with learning Modal logic are also researched.

Seven areas topics in Modal logic are investigated, as is the influence of domain independent factors (e. g. motivation) on learning. Studies show that students find concepts such as Modal proofs and systems difficult to learn, whilst possible worlds and Modes are fairly straightforward. Areas such as reference, belief and accessibility relations fall between these extremes.

Two roles for representations in reasoning are identified: providing a concrete domain for students to reason about, and supporting the process of reasoning. Systems which make use of these complementary representations were found to be more effective for learners than either the syntactic or the diagrammatic representations traditionally used to teach Modal logic.

A review of software used to support students learning logic highlights two important features: the use of examples, and automation of routine tasks. A learning environment for Modal logic was designed which incorporated these. The environment was developed using an adapted version of Smalltalk's Model-View-Controller mechanism, and incorporates complementary representations, enhance by direct manipulation.

A further study investigates the added benefits of using this tool, as opposed to using the same representation but working with pen and paper. This confirms the importance of using 'concrete' content representations and minimising learners' cognitive load. Performance measures show that software users learnt more, had a deeper style of learning, and found the topics less abstract than their counterparts working with pen & paper.

This research shows that complementary representations are an effective way of supporting students studying Modal logic, and that visualisation and manipulation tools which incorporate these systems will provide additional benefits for learners.
Utilization, access and outcome of surgical lumbar discectomy in British Columbia
Creators: name: Quon, Jeffrey
Publisher: name: University of British Columbia
Year: 2011

description: Lumbar discectomy is the most commonly performed operation on the spine. This thesis includes four studies on the utilization, access and outcome of lumbar discectomy in British Columbia. Studies 1 and 2 estimate temporal trends and regional variations in age- and sex adjusted lumbar discectomy rates using administrative data from the BC Linked Health Database. Study 1 shows that discectomy rates in public hospitals declined by 61% between 1990/91 and 2003/04. Rates declined faster after 2000/01 when lumbar discectomy became accessible in private clinics, preferentially for workers' compensation beneficiaries. Evidence of the diversion of compensated surgical patients from the public to private sectors was observed, however with no obvious attenuation of the decline in surgical rates for noncompensated patients remaining in the public system. In Study 2, rates of lumbar discectomy varied significantly between health service delivery areas (HSDAs), by almost five-fold during 2000/01-2003/04, up from 3.4 fold in 1990/91-1993/94. Studies 3 and 4 are based on prospective registry data on surgically treated lumbar disc patients at Vancouver General Hospital between November 1999 and December 2003. Study 3 identified significant sociodemographic and clinical determinants of waiting times in this population. Clinical severity (symptom duration, pain intensity) were appropriately associated, while most sociodemographic variables (age, sex, compensation status) were appropriately not associated with access to surgery. However professional occupation predicted waiting time, suggesting that access to surgery may not be based on clinical need alone. Study 4 estimated the effect of waiting 12 weeks or longer on the odds of pain improvement after lumbar discectomy. In propensity score-adjusted ordinal regression models, patients waiting 12 weeks or longer for surgery had a 41% lower odds of pain improvement. In the absence of declining disease prevalence, the implications of declining back surgery rates possibly include declining access to care and rising prevalence of disability in the community. This thesis research indicates that delayed access matters, and that "treatment within 12 weeks" may have utility as both a quality-of-care measure in health services research and as a benchmark for defining a maximum appropriate wait for lumbar discectomy.

description: We present a real-time stamp classifier of astronomical events for the ALeRCE (Automatic Learning for the Rapid Classification of Events) broker. The classifier is based on a convolutional neural network, trained on alerts ingested from the Zwicky Transient Facility (ZTF). Using only the \textit{science, reference} and \textit{difference} images of the first detection as inputs, along with the metadata of the alert as features, the classifier is able to correctly classify alerts from active galactic nuclei, supernovae (SNe), variable stars, asteroids and bogus classes, with high accuracy ($\sim$94\%) in a balanced test set. In order to find and analyze SN candidates selected by our classifier from the ZTF alert stream, we designed and deployed a visualization tool called SN Hunter, where relevant information about each possible SN is displayed for the experts to choose among candidates to report to the Transient Name Server database. From June 26th 2019 to February 28th 2021, we have reported 6846 SN candidates to date (11.8 candidates per day on average), of which 971 have been confirmed spectroscopically. Our ability to report objects using only a single detection means that 70\% of the reported SNe occurred within one day after the first detection. ALeRCE has only reported candidates not otherwise detected or selected by other groups, therefore adding new early transients to the bulk of objects available for early follow-up. Our work represents an important milestone toward rapid alert classifications with the next generation of large etendue telescopes, such as the Vera C. Rubin Observatory.

description: Code index modulated multi-carrier M-ary differential chaos shift keying (CIM-MC-M-DCSK) system not only inherits low-power and low-complexity advantages of the conventional DCSK system, but also significantly increases the transmission rate. This feature is of particular importance to Internet of Things (IoT) with trillions of low-cost devices. In particular, for e-health IoT applications, an efficient transmission scheme is designed to solve the challenge of the limited battery capacity for numerous user equipments served by one base station. In this paper, a new multiple-input-single-output simultaneous wireless information and power transfer (MISO-SWIPT) scheme for CIM-MC-M-DCSK system is proposed by utilizing orthogonal characteristic of chaotic signals with different initial values. The proposed system adopts power splitting mode, which is very promising for simultaneously providing energy and transmitting information of the user equipments without any external power supply. In particular, the new system can achieve desirable anti-multipath-fading capability without using channel estimator. Moreover, the analytical bit-error-rate expression of the proposed system is derived over multipath Rayleigh fading channels. Furthermore, the spectral efficiency and energy efficiency of the proposed system are analyzed. Simulation results not only validate the analytical expressions, but also demonstrate the superiority of the proposed system.

description: A precise measurement of a muon $(g-2)$ experiment recently reported a deviation from the Standard Model. This implies the need to an extension of the model and suggests underlying mechanisms. We hypothesize that the influence of higher dimensional gravity causes this $(g-2)$ deviation. This effect would appear as Kaluza-Klein modes and Nambu-Goldstone modes on a 3-brane. These classical effects produce new contributions to the magnetic moment. In this paper, we perform a consistency check by comparing the results derived from the Born and Schr{ö}dinger approximations. This comparison reveals a similarity between KK-dilaton modes and the brane stretching effect.

Properties of triangulated and quotient categories arising from $n$-Calabi-Yau triples

Subjects: subject: Representation Theory (math.RT)
subject: FOS: Mathematics

description: The original definition of cluster algebras by Fomin and Zelevinsky has been categorified and generalised in several ways over the course of the past 20 years, giving rise to cluster theory. This study lead to Iyama and Yang's generalised cluster categories $\mathcal{T}/\mathcal{T}^{fd}$ coming from $n$-Calabi-Yau triples $(\mathcal{T}, \mathcal{T}^{fd}, \mathcal{M})$. In this paper, we use some classic tools of homological algebra to give a deeper understanding of such categories $\mathcal{T}/\mathcal{T}^{fd}$. Let $k$ be a field, $n\geq 3$ an integer and $\mathcal{T}$ a $k$-linear triangulated category with a triangulated subcategory $\mathcal{T}^{fd}$ and a subcategory $\mathcal{M}=\text{add}(M)$ such that $(\mathcal{T}, \mathcal{T}^{fd}, \mathcal{M})$ is an $n$-Calabi-Yau triple. In this paper, we prove some properties of the triangulated categories $\mathcal{T}$ and $\mathcal{T}/\mathcal{T}^{fd}$. Our first result gives a relation between the Hom-spaces in these categories, using limits and colimits. Our second result is a Gap Theorem in $\mathcal{T}$, showing when the truncation triangles split. Moreover, we apply our two theorems to present an alternative proof to a result by Guo, originally stated in a more specific setup of dg $k$-algebras $A$ and subcategories of the derived category of dg $A$-modules. This proves that $\mathcal{T}/\mathcal{T}^{fd}$ is Hom-finite and $(n-1)$-Calabi-Yau, its object $M$ is $(n-1)$-cluster tilting and the endomorphism algebras of $M$ over $\mathcal{T}$ and over $\mathcal{T}/\mathcal{T}^{fd}$ are isomorphic. Note that these properties make $\mathcal{T}/\mathcal{T}^{fd}$ a generalisation of the cluster category.

description: This article aims to present the importance of contribution of ICT to Education, in relation to the learners and the teachers. At the same time, it aims at presenting the learners’ and teachers’ opinions about the usefulness of ICT. Firstly, ICT and its three basic models of use which have been incorporated into the school community are analyzed in this article. Then there is a comparison between the learners’ and teachers’ attitude toward ICT in the classroom. Also, pedagogical benefits and some of the disadvantages of ICT are unfolded. The methodology used is the review of modern, world-wide literature. ICT offers career development skills to a demanding world, that is incorporated into the “Society of Information” and it is constantly changing. A considerable number of teachers find it difficult to integrate them into the education, which is in contrast to trainees who tend to learn on technology. Teachers should understand, and then take advantage of pedagogical benefits of ICT, and adopt new teaching methods. Keywords: ICT, Society of Information, Education, Didactic Method, Evolution

description: First principles density functional calculations are used to study the early oxidation stages of the Mg(0001) surface for oxygen coverages 1/16 <= Theta <= 3 monolayers. It is found that at very low coverages O is incorporated below the topmost Mg layer in tetrahedral sites. At higher oxygen-load the binding in on-surface sites is increased but at one monolayer coverage the on-surface binding is still about 60 meV weaker than for subsurface sites. The subsurface octahedral sites are found to be unfavorable compared to subsurface tetrahedral sites and to on-surface sites. At higher coverages oxygen adsorbs both under the surface and up. Our calculations predict island formation and clustering of incorporated and adsorbed oxygen in agreement with previous calculations. The calculated configurations are compared with the angle-scanned x-ray photoelectron diffraction experiment to determine the geometrical structure of the oxidized Mg(0001) surface.

Planar first-passage percolation times are not tight

Subjects: subject: Probability (math.PR)

description: We consider first-passage percolation on the two-dimensional integer lattice Z^2 with passage times that are IID exponentials of mean one. It has been conjectured, based on numerical evidence, that the variance of the time T(0,n) to reach the vertex (0,n) is of order n^{2/3}. Kesten showed that the variance of T(0,n) is at O(n). He also noted that the variance is bounded away from zero. This note improves the lower bound on the variance of T(0,n) to C log n. Simultaneously and independently, Newman and Piza have achieved the same result for {0,1}-valued passage times. Their methods extend to more general passage times, while ours work only for exponential times. On the other hand, our theorem shows that the variance comes from fluctuations of nonvanishing probability in the sense that, as n->infty, the law of T(0,n) is not tight about its median. Very recently, Newman and Piza showed that the log n may be improved to a power of n for directions in which the shape is not flat (it is not known whether the shape can be flat in any direction). As pointed out to us by Harry Kesten, in the exponential case this may also be obtained via the method given here.

description: Pimento and Congo peppers are both important commercial crops in Trinidad but depend on irrigation for cultivation during the drier months. An experiment was conducted to compare six irrigation treatments (630 ml of water per plant per day and 950 ml of water per plant per day applied daily, every two days and every three days) on both landraces of pepper (Pimento and Congo). The crops were planted in January 2006 and harvesting was observed from April to July 2006. Comparison was made with a non-irrigated plot placed next to the experiment. The weather conditions were dry until the onset of the rainy season in late June. All plants in the non-irrigated plot died, but all of the irrigated plots gave pepper yields. However, there were no significant differences (P>0.05) in yield between the six irrigation treatments. The landraces were observed for differences in yield and size. Both landraces yielded similar amounts in April and June, but Pimento out-yielded Congo in May and July. Congo pepper fruits were generally larger than Pimento in the earlier harvests, especially for the plots with the higher irrigation amounts, but fruit sizes were similar in the later harvests. It was observed that there was a negative correlation between the number of flower abscission scars and fruit yield, and a positive correlation between the number of scars and fruit sizes. There were generally more flower abscission scars on Congo as compared to Pimento. Monthly yields were very variable; the June yields for Congo were only the equivalent of 6,000 kg/ha, but were at least six times that amount in May and July. Pimento yields were similar to Congo in May and July, but higher than Congo during June. The results show that both Congo and Pimento can be grown in dry conditions and the water requirements are not more than 630 ml/plant/day.

description: People moving between areas may contribute to the spread of plant pests by inadvertently carrying the pest on themselves, by transporting the pest on objects such as handicrafts, or by intentionally collecting and moving the pest. Visitors to the Greater Caribbean Region (GCR), the most heavily visited region in the world, arrive by air, water, or land, with air travel being predominant. Once in the GCR, visitors frequently move between countries. Cruise ship, ferry, and small boat passengers and people crossing land borders are often not subject to phytosanitary inspections. Inspection of airline passenger baggage is common, but cannot do justice to the ever-increasing passenger volume. The obvious potential of humans to facilitate pest spread, the immense number of travelers into and within the GCR, and an overall insufficient level of phytosanitary safeguards warrant that the pest risk associated with this pathway be considered very high. This work was carried out in the framework of the CISWG Caribbean Pathway Analysis. The complete report can be accessed at: http://carribeandoc. ncsu.edu/index.htm.
Quality of peat moss as a component of growing media
Creators: name: Mofidpoor, Maryam
Publisher: name: University of British Columbia

description: Quality of growing media is crucial for plant health and growth in nurseries and green houses. The objective of this study was to determine the effect of peat moss source and length of storage time on the quality of peat moss. Nine bales of peat moss collected from upper, less decomposed layer of a bog near lake Winnipeg in Manitoba and nine bales of peat moss excavated from lower, more decomposed layer of a bog near Vilna, Alberta were sampled after one, three, and 10 months of storage. The Manitoba peat moss had larger particle size, greater gravimetric water content, and greater NH4-N content relative to the peat moss from Alberta. The Alberta peat moss had higher pH, EC, and N03-N content. Plant available water content was the same in both peat moss. Particle size was decreased at 10 months storage time in both peat moss (based on wet sieving method), NH4-N content was reduced at 10 months in the Manitoba peat moss, N03-N was increased at three months in the Alberta peat moss, and EC was increased at three months in both peat moss. The result of this study suggested that the growing media industry should store peat moss for less than 10 months and the available N should be monitored on a regular basis.
The Dynamics of a Classical Spinning Particle in Vaidya Space-Time

description: Based on the Mathisson-Papapetrou-Dixon (MPD) equations and the Vaidya metric, the motion of a spinning point particle orbiting a non-rotating star while undergoing radiation-induced gravitational collapse is studied in detail. A comprehensive analysis of the orbital dynamics is performed assuming distinct central mass functions which satisfy the weak energy condition, in order to determine a correspondence between the choice of mass function and the spinning particle's orbital response, as reflected in the gravitational waves emitted by the particle. The analysis presented here is likely most beneficial for the observation of rotating solar mass black holes or neutron stars in orbit around intermediate-sized Schwarzschild black holes undergoing radiation collapse. The possibility of detecting the effects of realistic mass accretion based on this approach is considered. While it seems unlikely to observe such effects based on present technology, they may perhaps become observable with the advent of future detectors.

description: The staggered quark action on anisotropic lattices is studied. We carry out numerical simulations in the quenched approximation at three values of lattice spacing ($a_σ^{-1}=1-2$ GeV) with the anisotropy $ξ= a_σ/a_τ=4$, where $a_σ$ and $a_τ$ are the spatial and temporal lattice spacings, respectively. The bare anisotropy $γ_F$ in the quark action is numerically tuned through the ratio of meson masses in the fine and coarse directions, and through the dispersion relation of a meson, so that the renormalized fermionic anisotropy coincides with that of the gauge field. The discrepancy between these two calibration schemes provides an estimate of the finite lattice artifact, which is found to be sizable in the range of cutoff explored in this work. We also compute the meson masses using correlators with the wall source at the tuned anisotropy parameter. The flavor symmetry breaking effect smoothly decreases as $β$ increases. The effect of uncertainty in $γ_F$ on the meson masses are examined. We also discuss a perspective on dynamical simulations.

description: The increased availability of data on real networks has favoured an explosion of activity in the elaboration of models able to reproduce both qualitatively and quantitatively the measured properties. What has been less explored is the reliability of the data, and whether the measurement technique biases them. Here we show that tree-like explorations (similar in principle to traceroute) can indeed change the measured exponents of a scale-free network.

description: At the first meeting of the Plant Health Directors of the Caribbean Community (CARICOM) held during the period 23rd - 25th to April 2008, it was agreed to establish several technical working groups to address the issues relating to various pests of importance to the region. The meeting of CARICOM Technical Working Group on Tephritid Fruit Flies was held in Georgetown, Guyana during the period 16th " 17th September 2009. The general objective of this group is to safeguard the Caribbean from the threats and/or the impacts of introductions, economic damage and spread of Tephritid Fruit Flies through investigation/research and the provision of advise on all matters related to these fruit flies. Several tasks were assigned to Member States and Organizations, most of which have since been fulfilled and reported at the Second Meeting of CARICOM Plant Health Directors held during the period 4th - 5th March 2009. Achievements include a compilation of a list of existing confirmed species; identification of newly introduced species; a listing of species outside the region which pose a threat to the region; determination of species existing within the region which pose a threat to non-infested Caribbean countries; determination and recommendation of systems for prevention, management and/or eradication at the ports of entry and the field; keeping up-to-date with new methods of identification, spread, control and eradication; making recommendations on emergency preparedness for outbreaks; and advising on public awareness.

description: The aim of this study is to determine the competitiveness of the major producers of carrots in the region and whether production should be expanded to displace the current extra-regional imports. Problem: Trinidad, traditionally imported carrots from the USA; however, since 2005 this trade has been diverted to Costa Rica primarily through the signing of the bilateral arrangement with Costa Rica. In this case, the 40% CET has been waived, thus making it more attractive to import from Costa Rica. At the same time, CARICOM producers are seeking markets for their produce and any opportunities that lie therein. This study examined the market opportunities for carrots in the Caribbean Region and any opportunity that exist for the major carrot producer(s) in CARICOM. The study was done in an attempt to locate opportunities for small carrot producers who characterize the Region and to highlight the challenges they would face, both within their country and also those challenges which would arise through globalization. Jamaica was found to be the major CARICOM producer, and Trinidad and Tobago the major importer of carrots; however, no trade took place between these CARICOM partners. The study found that Jamaica was not price competitive against the two major suppliers to the Trinidad and Tobago market: Costa Rica and the USA. The results also show that a greater sum of domestic resources will be used to produce a unit of carrot compared to the foreign exchange earned against low market prices in Trinidad and Tobago. Thus Jamaica will not have a comparative advantage as it relates to the use of foreign exchange. In times when prices are high in the Trinidad and Tobago market, Jamaica will have a comparative advantage as it relates to the use of foreign exchange. There are, however, opportunities for Jamaica in this market if they can supply at more competitive prices as they were found to be uncompetitive when the competitor prices are low but marginally competitive when the competitors' prices increase on the market. Jamaica's high costs are associated with inefficiencies in the production process. Thus, should Jamaican carrot producers improve their agronomic practices, they would be able to effectively compete in this regional carrot market.

description: Many biological tissues, such as bones and ligaments, are fibrous. The geometrical structure of these tissues shows that they exhibit a similar hierarchy in their ultra-structure and macro-structure. The aim of this work is to develop a model to study the failure of fibrous structures subjected to dynamic loading. The important feature of this model is that it describes failure in terms of the loss of cohesion between fibres. We have developed a model based on the lamellar structure of compact bone with fibres oriented at 0 degrees, 45 degrees and 90 degrees to the longitudinal axis of the bone, and have studied the influence of the model parameters on the failure process. Bone porosity and joint stress force at failure were found to be the most significant parameters. Using least square resolution, we deduced a phenomenological model of the lamellar structure. Finally, experimental results were found to be comparable with our numerical model.
