description: Polygraphus grandiclava Thomson, 1886
(Curculionidae)
Ein Borkenkäfer mit eigenartigem, «doppeltem» ökologischem Auftreten: einerseits in niedrigen Lagen bevorzugt in Kirsche (Prunus avium L.), daneben in Bergwäldern überwiegend an Arve. Nach Pfeffer (1995) kommt er auch an Fichte vor. Ein genetischer Vergleich von Tieren aus Tal- und Bergpopulationen ergab Übereinstimmung, ein kryptisches Artenpaar liegt darum wohl nicht vor (M. Kahlen, pers. Mitt.).

description: Σκοπός της διατριβής ήταν η σχεδίαση έξυπνης ανακλαστικής επιφάνειας βασισμένης σε διάφανα υλικά. Εξετάσαμε αρχικά θεωρητικά τις τάσεις και τις εξελίξεις. Παρουσιάστηκαν εφαρμογές των έξυπνων ανακλαστικών επιφανειών στηριζόμενες στην βιβλιογραφία και τα άρθρα που μελετήθηκαν. Εν συνεχεία παρατέθηκε μεθοδολογία σχεδιασμού των έξυπνων ανακλαστικών επιφανειών όπως και μαθηματικά μοντέλα που την υποστηρίζουν. Αφού έγινε επαλήθευση με τη βοήθεια προγράμματος προσομοίωσης των υπαρχόντων μοντέλων και σύγκριση με υπάρχοντα αποτελέσματα σχεδιάστηκε και έγινε η προσομοίωση της προτεινόμενης «έξυπνης» ανακλαστικής επιφάνειας. Επίσης επιχειρήθηκε η σχεδίαση στοιχείων (unit cell),διαφορετικών γεωμετρικών χαρακτηριστικών, με σκοπό τη χρήση για κατασκευή των εν λόγω επιφανειών με τεχνικές “microfabrication” όπως και επιφανειών που λειτουργούν σε υψηλότερες συχνότητες. Τέλος παρατέθηκαν μελλοντικές δυνατότητες χρήσης μεθόδων “tuning” προκειμένου η σχεδιαζόμενη επιφάνεια να δύναται να παραμετροποιείται σε πραγματικό χρόνο
description: The aim of the present thesis was the design of intelligent reflection surface based on transparent materials. We examined current trends and evolution. Intelligent reflection surface applications were presented according to bibliography and articles studied. Furthermore analytical models and design methodology of intelligent reflective surfaces are both presented. Verification of this methodology and analytical models follow comparing current simulation results with already existing results and finally simulation of suggested intelligent reflective surface is conducted. Moreover different unit cells were designed, by varying geometric parameters, in order microfabrication techniques to be applied or higher frequencies to be served by surfaces that will be possibly fabricated in the future. Finally tuning methods, that can be potentially applied to unit cells, are presented

description: We study the transition of $ν=1/3$ and $2/5$ fractional quantum Hall states of the honeycomb Hofstadter model as we tune to a two-orbital moiré superlattice Hamiltonian, motivated by the flat bands of twisted bilayer graphene in a perpendicular magnetic field. In doing so, we address the extent to which these states survive in moiré systems and analyze the nature of the transition. Through the use of a Peierls substitution, we determine the Landau-level splitting for the moiré Hamiltonian, and study the structure of the Chern bands for a range of magnetic flux per plaquette. We identify topological flat bands in the spectrum at low energies, with numerically tractable lattice geometries that can support the fractional quantum Hall effect. As we tune the model, we find that the orbital-polarized $ν=1/3$ and $2/5$ states corresponding to the honeycomb Hofstadter model survive up to $\approx 30\%$ of typical moiré superlattice parameters, beyond which they transition into an insulating phase. We present evidence for this through density matrix renormalization group calculations on an infinite cylinder, by verifying the charge pumping, spectral flow, entanglement scaling, and conformal field theory edge counting. We conclude that fractional quantum Hall states from the Hofstadter model can persist up to hopping amplitudes of the same order as those typical for moiré superlattice Hamiltonians, which implies generally that fractional states for moiré superstructures can be discerned simply by analyzing the dominant terms in their effective Hamiltonians.

description: Recent work has highlighted agricultural land conversion as a significant debit in the greenhouse gas accounting of ethanol as an alternative fuel. This work has at the same time sparked considerable debate on the role of crop yield growth as a means of avoiding rapid land conversion. We examine the agricultural land use impacts of mandate driven ethanol demand increases in the United States in a formal economic equilibrium framework which allows us to examine the importance of yield price relationships. We find that the standard assumption of trend yield growth is likely restrictive for analysis of equilibrium response to significant demand increases for fuel feedstocks. Furthermore, we identify both the acreage response and bilateral trade specification of a multi-country model as important sources of variability (in terms of parametric uncertainty) in predicting global land use change from the biofuels boom.

description: Income inequalities as a result of the recent global financial crisis of 2009 have led to the intensification of migration and immigration, which has become more widespread and occurs not only from less to the more developed countries, but also among developed countries too. The latter of which is the one that is at the center of the scientific dialogue. This master thesis aims to study the phenomenon of brain-drain, meaning the outflow of scientific workforce, and its effects on countries of origin and host countries. More specifically, in this paper we examine the effects of brain-drain on two countries of the European Union, Greece and Germany. The OECD classifies both of these countries as developed ones. The objective of this master thesis is to present and compare the effects of brain-drain on a country that is losing scientific workforce (Greece) and on a country that is hosting it (Germany)

description: We report new high-quality galaxy scale strong lens candidates found in the Kilo Degree Survey data release 4 using Machine Learning. We have developed a new Convolutional Neural Network (CNN) classifier to search for gravitational arcs, following the prescription by \cite{2019MNRAS.484.3879P} and using only $r-$band images. We have applied the CNN to two "predictive samples": a Luminous red galaxy (LRG) and a "bright galaxy" (BG) sample ($r<21$). We have found 286 new high probability candidates, 133 from the LRG sample and 153 from the BG sample. We have then ranked these candidates based on a value that combines the CNN likelihood to be a lens and the human score resulting from visual inspection (P-value) and we present here the highest 82 ranked candidates with P-values $\ge 0.5$. All these high-quality candidates have obvious arc or point-like features around the central red defector. Moreover, we define the best 26 objects, all with scores P-values $\ge 0.7$ as a "golden sample" of candidates. This sample is expected to contain very few false positives and thus it is suitable for follow-up observations. The new lens candidates come partially from the the more extended footprint adopted here with respect to the previous analyses, partially from a larger predictive sample (also including the BG sample). These results show that machine learning tools are very promising to find strong lenses in large surveys and more candidates that can be found by enlarging the predictive samples beyond the standard assumption of LRGs. In the future, we plan to apply our CNN to the data from next-generation surveys such as the Large Synoptic Survey Telescope, Euclid, and the Chinese Space Station Optical Survey.

description: This paper introduces biofuels sectors as energy inputs into the GTAP data base and to the production and consumption structures of the GTAP-Energy model developed by Burniaux and Truong (2002), and further modified by McDougall and Golub (2008). We also incorporate Agro-ecological Zones (AEZs) for each of the land using sectors in line with Lee et al. (2005). The GTAP-E model with biofuels and AEZs offers a useful framework for analyzing the growing importance of biofuels for global changes in crop production, utilization, commodity prices, factor use, trade, land use change etc. We begin by validating the model over the 2001-2006 period. We focus on six main drivers of the biofuel boom: the hike in crude oil prices, replacement of MTBE by ethanol as a gasoline additive in the US, and subsidies for ethanol and biodiesel in the US and EU. Using this historical simulation, we calibrate the key elasticities of energy substitution between biofuels and petroleum products in each region. With these parameter settings in place, the model does a reasonably good job of predicting the share of feedstock in biofuels and related sectors in accordance with the historical evidence between 2001 and 2006 in the three major biofuel producing regions: US, EU, and Brazil. The results from the historical simulation reveal an increased production of feedstock with the replacement of acreage under other agricultural crops. As expected, the trade balance in oil sector improves for all the oil exporting regions, but it deteriorates at the aggregate for the agricultural sectors.

description: Although CGE models have received heavy usage, they are often criticized as being insufficiently validated. Key parameters are often not econometrically estimated, and the performance of the model as a whole is rarely checked against historical outcomes. As a consequence, questions frequently arise as to how much faith one can put in CGE results. In this paper, we employ a novel approach to the validation of a widely utilized global CGE model â€“ GTAP-E. By comparing the variance of model generated petroleum price distributions -- driven by historical demand and supply shocks to the model-- with observed five-year moving average price distributions, we conclude that energy demand in GTAP-E is far too price-elastic over this time frame. After incorporating the latest econometric estimates of energy demand and supply elasticities, we revisit the validation question and find the model to perform more satisfactorily. As a further check, we compare a deterministic global general equilibrium simulation, based on historical realizations over the 2001-2006 period during which petroleum prices rose sharply, along with growing global energy demands. As anticipated by the stochastic simulations, the revised model parameters perform much better than the original GTAP-E parameters in this global, general equilibrium context.

description: The human’s survival depends on the food security of the community. The over exploitation water
resources, along with climate change, have created a water crisis in the country. According to the high percentage of water resources allocated to agriculture compared with the environmental, drinking, and industrial ware right, getting out of this dilemma requires sustaining water and soil-based natural resources. Water user’s association (WUAs) seek to achieve sustainability in agriculture as a common goal of farmers and governments, by using social and human capital and with the enjoyment of partnership concept. Agricultural sustainability requires a sustainable development framework that includes political, economic, social and environmental sustainability in the agricultural sector. These NGOs pave the way for active and informed participation of farmers in water resources management to sustain agriculture, relying on the knowledge and ability of farmers and producers and in fact are local agents of creating backdrop of sustainable agricultural development in national and global thinking. Due to the ecological and ecosystem differences of each region, an integrative dynamic management system should be created for each region separately, based on more sub-management systems. The sustainability of farming requires collective action and alliance governance, and this integration is required to take place at higher levels by accepting political responsibility and desired governance. In this paper, the effects of Water user’s association on sustainability of farming are investigated given the context of sustainable development at the three levels: "Operation Unit", "Irrigation Network", and "National Level". Consequently, due to their regional function and supervisory, scientific and executive capacity, these organizations can create backdrop of agricultural land consolidation, reduction of conflicts of interest and disputes, participatory management of farmers, equitable distribution of water, development and prosperity of rural communities and farmers, adoption of new technologies for agricultural production, building trust between farmers and government agencies, transferring irrigation and drainage management to the private sector, and achieving the Purposes of the 44 principle Constitution of the Islamic Republic of Iran.

description: We propose a high-order discontinuous Galerkin scheme for nonlinear acoustic waves on polytopic meshes. To model sound propagation with and without losses, we use Westervelt's nonlinear wave equation with and without strong damping. Challenges in the numerical analysis lie in handling the nonlinearity in the model, which involves the derivatives in time of the acoustic velocity potential, and in preventing the equation from degenerating. We rely in our approach on the Banach fixed-point theorem combined with a stability and convergence analysis of a linear wave equation with a variable coefficient in front of the second time derivative. By doing so, we derive an a priori error estimate for Westervelt's equation in a suitable energy norm for the polynomial degree $p \geq 2$. Numerical experiments carried out in two-dimensional settings illustrate the theoretical convergence results. In addition, we demonstrate efficiency of the method in a three-dimensional domain with varying medium parameters, where we use the discontinuous Galerkin approach in a hybrid way.

description: Magnetic skyrmions are novel topological spin textures on the nanoscale, and significant efforts have been taken to improve their zero-field density at room temperature (RT). In this work, we reported an approach of improving zero-field skyrmion density in [Pt/Co/Fe/Ir]2 multilayers at RT by using the first-order reversal curve (FORC) technique. Firstly, we investigated the nucleation and annihilation mechanism of magnetic skyrmions using polar magneto-optical Kerr effect measurement. Secondly, the FORC technique was used to obtain information on the irreversible or reversible behaviors in the magnetization switching process. It was found from FORC diagram that the magnetization reversal mechanism can be characterized into three stages: (1) reversible labyrinth stripe domains expanding or shrinking stage; (2) irreversible stripe domains fracturing stage; and (3) irreversible skyrmion annihilation stage. At the end, we demonstrated that the zero-field skyrmion density can be highly improved by choosing reversal field from the irreversible stages. Our results have established the FORC measurement as a valuable tool for investigating magnetic multilayers of high skyrmion densities.

description: We review more than 10 years of continuous monitoring of accreting X-ray pulsars with the all-sky Gamma-ray Burst Monitor (GBM) aboard the Fermi Gamma-ray Space Telescope. Our work includes data from the start of GBM operations in August 2008, through to November 2019. Pulsations from 39 accreting pulsars are observed over an energy range of $10-50\,$keV by GBM. The GBM Accreting Pulsars Program (GAPP) performs data reduction and analysis for each accreting pulsar and makes histories of the pulse frequency and pulsed flux publicly available. We examine in detail the spin histories, outbursts and torque behaviors of the persistent and transient X-ray pulsars observed by GBM. The spin period evolution of each source is analyzed in the context of disk-accretion and quasi-spherical settling accretion driven torque models. Long-term pulse frequency histories are also analyzed over the GBM mission lifetime and compared to those available from the previous BATSE all-sky monitoring mission, revealing previously unnoticed episodes in some of the analyzed sources (such as a torque reversal in 2S 1845-024). We obtain new, or update known, orbital solutions for three sources. Our results demonstrate the capabilities of GBM as an excellent instrument for monitoring accreting X-ray pulsars and its important scientific contribution to this field.

description: As part of the Phytoliths in the Flora of Ecuador Project (PFE) (Pearsall 2016), phytolith assemblages from 82 surface soil samples from four distinctive vegetation formations, xerophytic coastal forest (Chanduy valley), mixed deciduous/evergreen forest (Jama region), coastal evergreen forest (Bilsa Biological Reserve), and Amazonian lowland forest (Jatun Sacha Biological Reserve) were studied, with the goal of establishing phytolith vegetation signatures to facilitate archaeological and paleoenvironmental phytolith interpretation. Proportions of diagnostic phytoliths were examined for each locality, separately, and phytolith patterning within the combined data set, i.e., all individual soil samples considered together, was explored through multivariate statistical analysis. Comparison of coastal (Bilsa) and Amazonian (Jatun Sacha) evergreen forests shows they cannot be distinguished using commonly occurring phytoliths and the rarer forms included in our study. Phytoliths are robust for identifying the evergreen forest biome. Comparison of xerophytic forest (Chanduy), dry (mixed deciduous/evergreen) forest (Jama), and moist forest of the coastal plain (Bilsa) reveals distinctive differences among these forests. Potential applications of our results include investigating the distribution of dry tropical forests in the past, identifying changes in moisture regimes over time, and tracking human impacts on different types of vegetation.

description: Tang derived the exact power formulae for t tests and analysis of covariance (ANCOVA) in superiority, noninferiority and equivalence trials. The power calculation in equivalence trials can be simplified by using Owen's Q function, which is available in standard statistical software. We extend the exact power determination method for ANCOVA to unstratified and stratified multi-arm randomized trials. The method is applied to the design of multi-arm trials and gold standard noninferiority trials.

description: The purpose of this paper is to examine empirically the impact of intellectual capital disclosure (IC) voluntarily. The empirical research is based on companies listed in the Dhaka Stock Exchange. The purpose of this paper is to investigate certain factors, which have not previously been presented in the literature, pertaining to intellectual capital performance in the Bangladeshi Banking and Insurance Sectors. An exploration of literature was performed to pick out the associated IC terminology and this examine adopts the scaffold for IC items developed by Bontis (2003). The aims of this study were to identify the determinants and the extent of intellectual capital disclosure among Bangladeshi listed financial companies. Then disclosure of these terms is examined within the annual reports of the financial year 2011-12 of the selected listed companies. It is exposed that, only 13 terms, out of 39 terms, are disclosed and average IC disclosure by companies in both sectors leftovers low. Banking sector has performed better than insurance sector in terms of number of companies reporting IC terms and average number of IC terms disclosed by a bank is found higher than that of an insurance company. But statistical outcome shows that there is no significant difference in mean number of companies disclosing an item of IC and average number of IC terms disclosed by banking and insurance companies at 5 percent level of significant.

description: In this article, we answer the following question: If the wave equation possesses bound states but it is exactly solvable for only a single non-zero energy, can we find all bound state solutions (energy spectrum and associated wavefunctions)? To answer this question, we use the "tridiagonal representation approach" to solve the wave equation at the given energy by expanding the wavefunction in a series of energy-dependent square integrable basis functions in configuration space. The expansion coefficients satisfy a three-term recursion relation, which is solved in terms of orthogonal polynomials. Depending on the selected energy we show that one of the potential parameters must assume a value from within a discrete set called the "potential parameter spectrum" (PPS). This discrete set is obtained from the spectrum of the above polynomials and can be either a finite or an infinite discrete set. Inverting the relation between the energy and the PPS gives the bound state energy spectrum. Therefore, the answer to the above question is affirmative.

The long term impact of nutrition education on students’ food attitudes and food choices
Creators: name: Belonio, Lauren
Publisher: name: The University of British Columbia
Year: 2023

description: This study explores how the knowledge and practical skills learned in Foods and Nutrition classes influences everyday food practices. The population sample consisted of ARMAC Secondary alumni students who had graduated between 2009- 2013, who had taken three or more years of Foods and Nutrition classes with me (Lauren Belonio) and who still resided in the Lower Mainland. Participants were recruited using social media, via a Facebook Study Page. The study began with an online questionnaire through FluidSurveys.com, where the students answered fifteen multiple-choice, questions, and had the option for participants to comment on each answer, regarding their experiences in Foods and Nutrition classes, as well as how they currently apply the skills and knowledge they learned. Answers to the questionnaires were analyzed for common perceptions and themes. The results from the study have implications for home economics educators in planning curriculum activities, that have a positive student response, as well as influencing the long-term food practices of students.

description: User demand for increasing amounts of wireless capacity continues to outpace supply, and so to meet this demand, significant progress has been made in new MIMO wireless physical layer techniques. Higher-performance systems now remain impractical largely only because their algorithms are extremely computationally demanding. For optimal performance, an amount of computation that increases at an exponential rate both with the number of users and with the data rate of each user is often required. The base station's computational capacity is thus becoming one of the key limiting factors on wireless capacity. QuAMax is the first large MIMO centralized radio access network design to address this issue by leveraging quantum annealing on the problem. We have implemented QuAMax on the 2,031 qubit D-Wave 2000Q quantum annealer, the state-of-the-art in the field. Our experimental results evaluate that implementation on real and synthetic MIMO channel traces, showing that 10~$μ$s of compute time on the 2000Q can enable 48 user, 48 AP antenna BPSK communication at 20 dB SNR with a bit error rate of $10^{-6}$ and a 1,500 byte frame error rate of $10^{-4}$.

Phase space formulation of density operator for non-Hermitian Hamiltonians and its application in quantum theory of decay

description: The Wigner-Weyl transform and phase space formulation of a density matrix approach are applied to a non-Hermitian model which is quadratic in positions and momenta. We show that in the presence of a quantum environment or reservoir, mean lifetime and decay constants of quantum systems do not necessarily take arbitrary values, but could become functions of energy eigenvalues and have a discrete spectrum. It is demonstrated also that a constraint upon mean lifetime and energy appears, which is used to derive the resonance conditions at which long-lived states occur. The latter indicate that quantum dissipative effects do not always lead to decay but, under certain conditions, can support stability of a system.

Water Adsorption in Soft and Heterogeneous Nanopores

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Liquids under confinement differ in behavior from their bulk counterparts and can acquire properties that are specific to the confined phase and linked to the nature and structure of the host matrix. While confined liquid water is not a new topic of research, the past few years have seen a series of intriguing novel features for water inside nanoscale pores. These unusual properties arise from the very specific nature of nanoporous materials: termed "soft porous crystals", they combine large-scale flexibility with a heterogeneous internal surface. This creates a rich diversity of behavior for the adsorbed water, and the combination of different experimental characterization techniques along with computational chemistry at various scales is necessary to understand the phenomena observed, and their microscopic origins. The range of systems of interest span the whole chemical range, from the inorganic (zeolites, imogolites) to the organic (microporous carbons, graphene and its derivatives) and even encompass the hybrid organic--inorganic systems (such as metal--organic frameworks).
The evolution of “Humanities and Travel” : enhancing curricular connections in school sponsored student funded travel
Creators: name: Crouse, Richard Dean
Publisher: name: The University of British Columbia
Year: 2023

description: Most would agree that travel abroad is a worthwhile and educative endeavour. Assuming this to be true it is the object of the research described in this paper to investigate the process, practice and results of educator-directed travel experiences for high-school students. The vast majority of the relevant literature available deals understandably with tertiary (post-secondary) education, detailing surveys of students’ experiences either in company with other young people or alone, while the ages of the participants range from late teens through to late twenties. The overwhelming conclusions, while informative and revealing, are by their nature relevant only to tertiary and not secondary education. The latter has not been sufficiently investigated. One result of the project will be the creation and development of a program with a curricular focus on Comparative Civilizations and English Studies which ideally will be an in-depth cultural study, culminating with a trip “on location” in Europe. Areas covered will necessarily include the ecological impact of travel abroad and the concerns of local populations about sustainability and sensible consumerism. The research will include personal anecdotal experiences and those of others. This empirical approach, while not scientific and strictly quantitative, should nevertheless support the findings derived from the published investigations of those who have examined the secondary experience. The value of qualitative research will be acknowledged by use being made of information garnered from students’ (informal) interviews. Studies which are anecdotal may not by their nature be statistically sophisticated, but as with the information available in the studies of the tertiary experience mentioned above will contribute to an enriched illustration of the secondary experience. Travel lends itself to anecdote and stories of personal experience, not to say cautionary tales for the enlightenment of the unwary uninitiated. This inquiry into the educational impact of secondary school sponsored student travel abroad will contribute to the academic literature while the program will be a model for other educators to realise and adapt to their own needs and circumstances.
