An investigation into sugar cane versus wood fibre paper
Creators: name: Carniato, Ryan

name: Yeung, Wilson
Publisher: name: The University of British Columbia
Year: 2014

description: This paper uses the triple bottom line method to compare wood fibre paper and sugar cane paper's economic, environmental, and social aspects. Specifically, this investigation focuses on the company TreeZero's sugar cane paper to compare against the 30% recycled wood fibre paper used at the University of British Columbia. The investigation relies heavily on scholarly articles, trustworthy online articles, public surveys, and information provided by TreeZero. On the economic front, the supply and demand were measured to ensure that TreeZero has more than enough supply to provide UBC of its needs, and the final price is assumed to be the same. However, any investment made into TreeZero is an investment into foreign economics instead of local. On the social front, the CEO of TreeZero claims that their employees are treated extremely well with above average wages, health plans, insurance and benefits. If true, then risk of serious respiratory illness caused by working with bagasse should be minimal. Also, through public survey of 197 students, most students do knot know much about sugar cane paper but show support towards UBC transitioning to sugar cane paper. On the environmental front, the investigation of the raw material support that sugar cane is the best choice for the university; however, based on the carbon dioxide emission both papers are the same. Investigation on energy requirement, waste generation, SO₂ and NOx emission, chemical waste of pulping/bleaching process, renewability and life cycle reveal that sugar cane is more suitable for the environment. The findings indicate that sugar cane paper is the better option of the two for UBC. Given that it is not possible to produce sugar cane locally there may be other alternative sources worth considering. However, the public appears ready to adopt alternate sources even with minimal information and they have an interest in promoting UBC's image as a leader in sustainability initiatives.

description: We use previous work on the Hilbert space for mixed fields to derive deformed dispersion relations for neutrino flavor states. We then discuss how these dispersion relations may be incorporated into frameworks encoding the breakdown of Lorentz invariance. We consider non-linear relativity schemes (of which doubly special relativity is an example), and also frameworks allowing for the existence of a preferred frame. In both cases we derive expressions for the spectrum and end-point of beta decay, which may be used as an experimental probe of the peculiar way in which neutrinos experience Lorentz invariance.

Cosmic String from D-term Inflation and Curvaton

description: We study effects of the cosmic string in the D-term inflation model on the cosmic microwave background (CMB) anisotropy. In the D-term inflation model, gauged cosmic string is usually formed, which may significantly affect the CMB anisotropy. We see that its study imposes important constraint. In order to realize the minimal model of D-term inflation, we see that the coupling constant λin the superpotential generating the inflaton potential should be significantly small, λ\lesssim O(10^{-4}-10^{-5}). We also discuss that a consistent scenario of the D-term inflation with λ\sim 1 can be constructed by adopting the curvaton mechanism where the cosmic density fluctuations are generated by a primordial fluctuation of a late-decaying scalar field other than the inflaton.

description: This paper analyses the nexus between global competitiveness and the attainment of the Vision 20:2020 agenda of the Federal Government of Nigeria. In doing this, the paper reviews the key elements of Vision 20/2020, the pillars of global competitiveness and the ranking of Nigeria on global indicators of competitiveness (GCI), size (GDP) and living standards (PCI). The goal is to assess the challenges Nigeria must overcome to achieve Vision 20:2020, given the significance of global competitiveness in determining national productivity and living standards, and the significance of economic growth and growth in exports. The assessment of the Vision’s targets against the background of Nigeria’s performances on global rankings indicates that realizing the Vision 20:2020 would be challenging though, not impossible. Nigeria’s political elite must recognize that achieving global competitiveness is a necessary condition for attaining the goals of Vision 20:2020. They must also be willing to deploy greater political commitment, sound knowledge and good judgment, and improve governance by reducing corruption and raising the ethical standards in the management of the economy.

description: The stability and conservation properties of a recently proposed polymerization model are studied. The achiral (racemic) solution is linearly unstable once the relevant control parameter (here the fidelity of the catalyst) exceeds a critical value. The growth rate is calculated for different fidelity parameters and cross-inhibition rates. A chirality parameter is defined and shown to be conserved by the nonlinear terms of the model. Finally, a truncated version of the model is used to derive a set of two ordinary differential equations and it is argued that these equations are more realistic than those used in earlier models of that form.

description: Using the recently introduced multiloop extension of the functional renormalization group, we compute the frequency- and momentum-dependent self-energy of the two-dimensional Hubbard model at half filling and weak coupling. We show that, in the truncated-unity approach for the vertex, it is essential to adopt the Schwinger-Dyson form of the self-energy flow equation in order to capture the pseudogap opening. We provide an analytic understanding of the key role played by the flow scheme in correctly accounting for the impact of the antiferromagnetic fluctuations. For the resulting pseudogap, we present a detailed numerical analysis of its evolution with temperature, interaction strength, and loop order.

description: Let K be the subgroup of the extended mapping class group, Mod(S), generated by Dehn twists about separating curves. Assuming that S is a closed, orientable surface of genus at least 4, we confirm a conjecture of Farb that Comm(K), Aut(K) and Mod(S) are all isomorphic. More generally, we show that any injection of a finite index subgroup of K into the Torelli group I of S is induced by a homeomorphism. In particular, this proves that K is co-Hopfian and is characteristic in I. Further, we recover the result of Farb and Ivanov that any injection of a finite index subgroup of I into I is induced by a homeomorphism. Our method is to reformulate these group theoretic statements in terms of maps of curve complexes.

The targum (1955:Feb. 2 - 1955:Feb. 25)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1955

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: In this paper we compare the standard dynamic programming method for the derivation of closed form solutions to stochastic control problems with three alternatives. Our first alternative is a minor variant of dynamic programming which requires solution of an alternative partial differential equation. In the context of a ba.sic, stochastic intertemporal utility maximizing model, this alternative solution procedure is particularly useful when preferences are represented by an instantaneous profit function. Our second alternative is based on intertemporal duality theory, and is most useful when preferences are represented by an indirect intertemporal expected utility (or value) function. Our third alternative is based on matching restrictions across inverse marginal instantaneous and indirect intertemporal expected utility functions - Gorman "expenditure" and "wealth" functions. Each of the approaches is suitable to particular model specifications and preference representations. As a collection of methods based to varying degrees on the exploitation of separability and duality, the methodology of this paper may be termed 'Gormanesque' (in the. spirit of Gorman (1976)). Taken together, these methods expand considerably the range of models for which closed form analytical solutions may be obtained.

description: We report on an apparent low-energy nanoscale electronic inhomogeneity in FeSe$_{0.4}$Te$_{0.6}$ due to the distribution of selenium and tellurium atoms revealed through unsupervised machine learning. Through an unsupervised clustering algorithm, characteristic spectra of selenium- and tellurium-rich regions are identified. The inhomogeneity linked to these spectra can clearly be traced in the differential conductance and is detected both at energy scales of a few electron volts as well as within a few millielectronvolts of the Fermi energy. By comparison with ARPES, this inhomogeneity can be linked to an electron-like band just above the Fermi energy. It is directly correlated with the local distribution of selenium and tellurium. There is no clear correlation with the magnitude of the superconducting gap, however the height of the coherence peaks shows significant correlation with the intensity with which this band is detected, and hence with the local chemical composition.

description: This study estimates the degree of habit formation and demand for the U.S. non-alcoholic beverage market by incorporating a dynamic effect in five different beverages. This study employs a linear-approximate almost ideal demand system (LA-AIDS) to model demand for five non-alcoholic beverages from 1974 through 2014. The results show that current consumption of all non-alcohol beverages is positively related to previous consumption by controlling price and expenditure. This study mainly finds that bottled water is the most habitual product of the non-alcoholic beverage group.

Cosmological string backgrounds from super Poisson-Lie T-plurality

description: We generalize the formulation of Poisson-Lie (PL) T-plurality proposed by R. von Unge [JHEP 07 (2002) 014] from Lie groups to Lie supergroups. By taking a convenient ansatz for metric of the $σ$-model in terms of the left-invariant one-forms of the isometry Lie supergroups $(C^3 +A)$ and $GL(1|1)$ we construct cosmological string backgrounds, including $(2+1|2)$-dimensional metric, time-dependent dilaton and vanishing torsion, in a way that they satisfy the one-loop beta-function equations. Starting from the decompositions of semi-Abelian Drinfeld superdoubles (DSDs) generated by the $({\C}^3 +{\A})$ and $gl(1|1)$ Lie super bi-algebras we find the conformal duality/plurality chains of $2+1$-dimensional cosmological string backgrounds coupling with two fermionic fields. In particular, the new backgrounds obtained by the super PL T-plurality remain conformally invariant at one-loop level. This work can prompt many new insights into supergravity and obviously has interesting mathematical relations with double field theory.

description: We present the results of a new epoch of a long-term photometric monitoring of the variable planetary nebula IC~4997. The integral $UBV$ light curves display a continuing brightening of 0.$^{m}15$ in $V$, a slight rise (<0.$^{m}1$) in $B$, and constancy in $U$. The $B-V$ color has got redder from 0.$^{m}4$ in 2000 to 0.$^{m}7$ in 2019, whereas the $U-B$ color has not changed significantly. New $JHKL$ photometry was obtained in 2019. We found the source to be fainter by 0.$^{m}4$ in $L$ and bluer by 0.$^{m}2$ in the $K-L$ color if compared to the data of 1999-2006. The long-term brightness variations are due mostly to the changing input of emission lines to the integral light. Low-dispersion spectroscopic observations carried out in 2010-2019 revealed a continuing decrease in the $\lambda4363/\lambda4340$ ratio: it decreased by a factor of $\sim3$ in 30 years and reached the level of 1960-1970. The absolute intensities of [OIII] nebualr lines increased by a factor of $>2$ from 1990 to 2019, whereas the [OIII] $λ$4363 line had weakened by a factor of 2 comparing to the maximum value observed in 2000. The variation of H$β$ absolute intensity in 1960-2019 was shown to be similar to that of [OIII] nebular lines, but of smaller amplitude. The electron density in the outer part of the nebula was estimated from the [SII] and [ClIII] lines. Basing on the data on absolute intensities we propose a possible scenario describing the change of $N_e,T_e$ in 1970-2019. The spectral variability of IC~4997 could be explained by a variation of electron temperature in the nebula caused by not so much the change in ionizing flux from the central star as the variable stellar wind and related processes. The photometric and spectral changes observed for IC~4997 in 1960-2019 may be interpreted as an observable consequence of a single episode of enhanced mass loss from the variable central star.

Dark matter as a heavy thermal hot relic

description: If, during the early Universe epoch, the dark matter particle thermalizes in a hidden sector which does not thermalize with the Standard Model thermal bath, its relativistic thermal decoupling can easily lead to the observed relic density, even if the dark matter particle mass is many orders of magnitude heavier than the usual $\sim$ eV hot relic mass scale. This straightforward scenario simply requires that the temperature of the hidden sector thermal bath is one to five orders of magnitude cooler than the temperature of the Standard Model thermal bath. In this way the resulting relic density turns out to be determined only by the dark matter mass scale and the ratio of the temperatures of both sectors. In a model independent way we determine that this can work for a dark matter mass all the way from $\sim 1$ keV to $\sim 30$ PeV. We also show how this scenario works explicitly in the framework of two illustrative models. One of them can lead to a PeV neutrino flux from dark matter decay of the order of the one needed to account for the high energy neutrinos observed by IceCube.

description: Ion beam therapy has become a frequently applied form of cancer therapy over the last years. The advantage of ion beam therapy over conventional radiotherapy using photons is the strongly localized dose deposition, leading to a reduction of dose applied to surrounding healthy tissue. Currently, treatment planning for proton therapy is based on X-ray computed tomography, which entails certain sources of inaccuracy in alculation of the stopping power (SP). A more precise method to acquire the SP is to directly use high energy protons (or other ions such as carbon) and perform proton computed tomography (pCT). With this method, the ions are tracked prior to entering and after leaving the patient and finally their residual energy is measured at the very end. Therefore, an ion imaging demonstrator, comprising a tracking telescope made from double-sided silicon strip detectors and a range telescope as a residual energy detector, was set up. First measurements with this setup were performed at beam tests at MedAustron, a center for ion therapy and research in \mbox{Wiener Neustadt}, \mbox{Austria}. The facility provides three rooms for cancer treatment with proton beams as well as one which is dedicated to non-clinical research. This contribution describes the principle of ion imaging with proton beams in general as well as the design of the experimental setup. Moreover, first results from simulations and recent beam tests as well as ideas for future developments will be presented.

description: Asteroids are remnants of the material from which the Solar System formed. Fragments of asteroids, in the form of meteorites, include samples of the first solid matter to form in our Solar System 4.5 mia years ago. Spectroscopic studies of asteroids show that they, like the meteorites, range from very primitive objects to highly evolved small Earth-like planets that differentiated into core mantle and crust. The asteroid belt displays systematic variations in abundance of asteroid types from the more evolved types in the inner belt to the more primitive objects in the outer reaches of the belt thus bridging the gap between the inner evolved apart of the Solar System and the outer primitive part of the Solar System. High-speed collisions between asteroids are gradually resulting in their break-up. The size distribution of kilometer-sized asteroids implies that the presently un-detected population of sub-kilometer asteroids far outnumber the known larger objects. Sub-kilometer asteroids are expected to provide unique insight into the evolution of the asteroid belt and to the meteorite-asteroid connection. We propose a space mission to detect and characterize sub-kilometer asteroids between Jupiter and Venus. The mission is named Bering after the famous navigator and explorer Vitus Bering. A key feature of the mission is an advanced payload package, providing full on board autonomy of both object detection and tracking, which is required in order to study fast moving objects in deep space. The autonomy has the added advantage of reducing the cost of running the mission to a minimum, thus enabling science to focus on the main objectives.

An investigation into introducing liquid sweeteners : sustainability project report

Publisher: name: The University of British Columbia
Year: 2014

description: In some of UBC Food Services' locations, dry sweetener portion packets and other sweetening products have been replaced by pumps that dispense liquid sweeteners (LS). The overall impacts of this change on the sustainability of UBC’s operations are evaluated using a triple bottom line assessment. Through online research and contacting key stakeholders through surveys, the economic, social, and environmental differences between the two options were determined. While the price of LS is higher than dry packets, there might be a reduction in consumption due to decreases in waste and theft. Paper waste from dry packets cannot be composted or recycled due to the chemicals in their inks and plastic linings. LS do not produce paper waste; the plastic bottles can be recycled while the pumps are durable enough to be washed and reused often. The LS manufacturer, Monin, is located in the United States so their products need higher carbon emissions to transport compared to the Canadian dry sugar packet manufacturers. Purchasing from a Canadian manufacturer would also have a greater benefit to Canada's economy. Fair Trade and sustainability programs are supported by all the major sweetener manufacturers. The interviewed LOOP Cafe employees stated that they did not find that there was a significant difference in the time or effort required to set up and/or keep up the LS stations compared to dry sugar packet stations. In the consumer survey, more than half of the participants stated that they have taken extra packets to use at home or disposed of unused packets. As a result, LS should be introduced to more UBC Food Services locations in the future and posters should be displayed to raise consumer awareness.

description: Dual-function radar-communications (DFRC) systems implement radar and communication functionalities on a single platform. Jointly designing these subsystems can lead to substantial gains in performance as well as size, cost, and power consumption. In this paper, we propose a DFRC system, which utilizes generalized spatial modulation (GSM) to realize coexisting radar and communications waveforms. Our proposed GSM-based scheme, referred to as spatial modulation based communication-radar (SpaCoR) system, allocates antenna elements among the subsystems based on the transmitted message, thus achieving increased communication rates by embedding additional data bits in the antenna selection. We formulate the resulting signal models, and present a dedicated radar processing scheme. To evaluate the radar performance, we characterize the statistical properties of the transmit beam pattern. Then, we present a hardware prototype of the proposed DFRC system, demonstrating the feasibility of the scheme. Our results show that the proposed GSM system achieves improved communication performance compared to techniques utilizing fixed allocations operating at the same data rate. For the radar subsystem, our experiments show that the spatial agility induced by the GSM transmission improves the angular resolution and reduces the sidelobe level in the transmit beam pattern compared to using fixed antenna allocations.

description: Density matrix renormalization group methods are used to investigate the quantum phase diagram of a one-dimensional half-filled ionic Hubbard model with bond-charge attraction, which can be mapped from the Su-Schrieffer-Heeger-type electron-phonon coupling at the antiadiabatic limit. A bond order wave (dimerized) phase which separates the band insulator from the Mott insulator always exists as long as electron-phonon coupling is present. This is qualitatively different from that at the adiabatic limit. Our results indicate that electron-electron interaction, ionic potential and quantum phonon fluctuations combine in the formation of the bond-order wave phase.

description: We describe a simple machinery which translates results on algebraic sums of sets of reals into the corresponding results on their cartesian product. Some consequences are: 1. The product of a meager/null-additive set and a strong measure zero/strongly meager set in the Cantor space has strong measure zero/is strongly meager, respectively. 2. Using Scheepers' notation for selection principles: Sfin(Omega,Omega^gp)\cap S1(O,O)=S1(Omega,Omega^gp), and Borel's Conjecture for S1(Omega,Omega) (or just S1(Omega,Omega^gp)) implies Borel's Conjecture. These results extend results of Scheepers and Miller, respectively.

description: We present a modular cosmology scenario where the difficulties encountered in conventional modular cosmology are solved in a self-consistent manner, with definite predictions to be tested by observation. Notably, the difficulty of the dilaton finding its way to a precarious weak coupling minimum is made irrelevant by having eternal modular inflation at the vacuum supersymmetry breaking scale after the dilaton is stabilised. Neither this eternal inflation nor the subsequent non-slow-roll modular inflation destabilise the dilaton from its precarious minimum due to the low energy scale of the inflation and consequent small back reaction on the dilaton potential. The observed flat CMB spectrum is obtained from fluctuations in the angular component of a modulus near a symmetric point, which are hugely magnified by the roll down of the modulus to Planckian values, allowing them to dominate the final curvature perturbation. We also give precise calculations of the spectral index and its running.

description: The study was carried out to appraise the economics of rubber production in rural Nigeria. Secondary data were used for the study. The data collected were analysed using budgetary analysis and multiple regression model. The Net Farm Profit of N176, 657.88 and N213, 105.71 per hectare for Ilushin Rubber Estate Limited (IREL) and Waterside Rubber Estate Limited (WAREL), respectively was an indication of the economic viability of rubber enterprise. The cost structure of the two rubber estates indicated that rubber enterprise requires huge capital outlay and is labour intensive. The results of the multiple regression revealed that labour input, transportation cost, maintenance cost, agrochemical and age of the tree were the determinants of rubber output. The study thus recommends the checking of the system of land acquisition in the country to enable potential investors venture into such a land demanding investment as rubber enterprise. Also, provision of sustainable credit is recommended as rubber enterprise is capital intensive. Lastly, existing policies on plantation establishment should be reviewed and enabling environment provided to ensure local consumption of rubber products.
Fröhlich-coupled qubits interacting with fermionic baths

subject: FOS: Physical sciences

description: We consider a macroscopic quantum system such as a qubit, interacting with a bath of fermions as in the Fröhlich polaron model. The interaction Hamiltonian is thus linear in the macroscopic system variable, and bilinear in the fermions. Using the recently developed extension of Feynman-Vernon theory to non-harmonic baths we evaluate quadratic and the quartic terms in the influence action. We find that for this model the quartic term vanish by symmetry arguments. Although the influence of the bath on the system is of the same form as from bosonic harmonic oscillators up to effects to sixth order in the system-bath interaction, the temperature dependence is nevertheless rather different, unless rather contrived models are considered.

description: Small planets are common around late-M dwarfs and can be detected through highly precise photometry by the transit method. Planets orbiting nearby stars are particularly important as they are often the best-suited for future follow-up studies. We present observations of three nearby M-dwarfs referred to as EIC-1, EIC-2, and EIC-3, and use them to search for transits and set limits on the presence of planets. On most nights our observations are sensitive to Earth-sized transiting planets, and photometric precision is similar to or better than TESS for faint late-M dwarfs of the same magnitude (I=15 mag). We present our photometry and transit search pipeline, which utilizes simple median detrending in combination with transit least squares based transit detection (Hippke & Heller 2019).For these targets, and transiting planets between one and two Earth radii, we achieve an average transit detection probability of 60% between periods of 0.5 and 2 days, 30% between 2 and 5 days,and 10% between 5 and 10 days. These sensitivities are conservative compared to visual searches.

description: We present calculations of the equilibrium current density and Chern numbers for a 2DEG in a periodic potential with infinite strip geometry and a perpendicular magnetic field. We consider a triangular lattice of anti-dots with large (a = 120 nm) lattice spacing. Such a system is known as artificial graphene (AG). To compute the current density we numerically diagonalise the AG Hamiltonian over a set of Landau level basis states, this takes into account coupling between different Landau levels. Our calculations show that, at magnetic fields typical for quantum Hall measurements, extended streams of current are present in the bulk of the sample. We investigate the scaling of these streams with potential strength. Knowledge of the AG energy levels allows us to compute the Chern number associated with each energy gap. We demonstrate that in tuning the height of the potential modulation the Chern number can undergo a transition between two different values.

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In 1994 V4332 Sgr underwent a mysterious eruption. Somehow its fast evolution towards a red giant star was, lacking alternative classifications, connected to the red variable M31 RV, which had its eruption in 1988. The red eruptive variable V838~Mon draw in February 2002 the attention back to its 'older twin' V4332~Sgr. The new precise photometry of the progenitor given here shows that the object started to rise years before the 1994 event. Post outburst photometry and spectroscopy from 2002 and 2003 show that the object stopped it's decline and seem to reheat now. The progenitor data and the new high quality spectra provide a supplement and completion to the data around the outburst given by Martini et al. (1999). It thus allows theorists to give new boundaries for modelling of this unusual object.

THE FARM SIZE-EFFICIENCY RELATIONSHIP IN SOUTH AFRICAN COMMERCIAL AGRICULTURE

description: This paper briefly discusses the sources of economies of scale, with some international evidence. It provides a picture of the structure of South African agriculture, detailing distributions of Jann size as well as some results of previous studies analysing Jann size efficiencies. An analysis of Jann size-efficiency relationship in commercial fanning is done by utilising representative Jann level survey data on the six major grain producing areas and an irrigation area over the period 1975-1990. The role of policy in explaining these relationships is discussed, while some conclusions are also drawn. The findings have specific implications for land re/om,. The inverse Jam, size-efficiency relationship, which is also present in South African agriculture despite a history of policies favouring relatively large mechanised fam,s, implies that significant efficiency gains can be made if Jam, sizes in the commercial sector becomes smaller. An important element in such a process would be the removal of all policies and distortions favouring larger farms relative to smaller farms.
