description: Adhesion is a key issue for researchers of various fields, it is therefore of uppermost importance to understand the parameters that are involved. Commonly, only surface parameters are employed to determine the adhesive forces between materials. Yet, van der Waals forces act not only between atoms in the vicinity of the surface, but also between atoms in the bulk material. In this review, we describe the principles of van der Waals interactions and outline experimental and theoretical studies investigating the influence of the subsurface material on adhesion. In addition, we present a collection of data indicating that silicon wafers with native oxide layers are a good model substrate to study van der Waals interactions with coated materials.

description: We have revisited the prospects of Supersymmetry(SUSY) searches at the LHC with 7 TeV energy along with the prediction of the discovery potential at 8 TeV energy assuming an integrated luminosity 5 $fb ^{-1}$ and 20 $\invfb$ with mSUGRA/CMSSM as a model framework. We discuss further optimization of our selection strategy which is based on the hadronic event shape variables. Evaluating the standard model backgrounds and signal rates in detail we predict the discovery reach in the $m_0 - m_{1/2}$ plane for 7 TeV with 5$\invfb$ luminosity. We also present the discovery reach for 8 TeV energy with an integrated luminosity 5$\invfb$ and 20 $\invfb$. A comparison is made between our results and the exclusion plots obtained by CMS and ATLAS. Finally, discovery reach in the gluino and squark mass plane at the 7 TeV and 8 TeV energy is also presented.

description: It has now been about five months since President Obama announced his strategy of increasing troops in Afghanistan and a vague commitment to withdrawing most U.S. troops beginning in mid-2011.  The administration began back pedaling from that pledge almost immediately after Obama made it.  With the deadline for withdrawing troops only slightly more than a year away, that goal seems more remote today than it did a year ago. In recent months, the war, which is now in its ninth year, has begun to feel like a permanent part of the political landscape.

Transcriptome evolution in black cottonwood (Populus trichocarpa)
Creators: name: Ono, Jasmine
Publisher: name: University of British Columbia
Year: 2012

description: In 1975, King and Wilson proposed that gene expression variation can play a role in the evolution of phenotypic variation since the variation in nature could not be explained by variation in protein coding sequences alone. When a mutation which causes a change in gene expression is introduced in to a population, either selection or neutral drift can act on it. When this mutation causes no change in fitness of the organism, it will be affected by neutral drift. The bounds for neutral drift are thought to be set by stabilizing selection. If the mutation is beneficial to the organism, it will be affected by positive selection. When different populations are located in different environmental conditions, different mutations can be beneficial in each population and divergent selection can result. We looked for these patterns of gene expression evolution among populations of Populus trichocarpa, black cottonwood,using a PST vs. FST approach. P. trichocarpa is a model tree system that allows the study of an extended suite of tree biological processes. A suite of genomic tools have been developed for black cottonwood, including a genome sequence and a 15.5K microarray. It is broadly distributed in the far west of North America and shows an ecotypic mode of genetic differentiation, with populations divided into northern and southern groups. In this study, we examined gene expression from 12 P. trichocarpa populations, 6 from the north and 6 from the south. We found evidence for divergent selection acting on the expression values of many genes, as well as stabilizing selection acting on a few. This supports the prevalence of natural selection acting on phenotypic traits, but we still found an overwhelming majority of traits which seem to be drifting neutrally. We found no evidence for different selection acting on the northern and southern groups.

description: Many complex systems have been shown to share universal properties of organization, such as scale independence, modularity and self-similarity. We borrow tools from statistical physics in order to study structural preferential attachment (SPA), a recently proposed growth principle for the emergence of the aforementioned properties. We study the corresponding stochastic process in terms of its time evolution, its asymptotic behavior and the scaling properties of its statistical steady state. Moreover, approximations are introduced to facilitate the modelling of real systems, mainly complex networks, using SPA. Finally, we investigate a particular behavior observed in the stochastic process, the peloton dynamics, and show how it predicts some features of real growing systems using prose samples as an example.

Impacts of Weather on Urban Bus Performance in the City of Calgary, Alberta

Publisher: name: Schulich School of Engineering
Year: 2023
Subjects: subject: Sociology--Transportation

description: There is an extensive body of literature on the impacts of adverse weather on traffic performance and transit ridership; however, only a few research have investigated the impacts of adverse weather on urban bus performance. Traffic congestion and unfavourable road conditions caused by adverse weather directly affect the performance of buses. Also, adverse weather impacts buses indirectly by affecting the passengers. This study aims to evaluate the impacts of adverse weather (rainy and snowy weather) on urban bus performance in the City of Calgary. This research focuses on the impacts of rain and snow on seven bus routes in the City of Calgary. Calgary Transit provided the automatic vehicle location and automatic passenger counter data for 2019-2021. The weather data was supplied by the Calgary International Airport and included daily snowfall and 5-minute rainfall data from 16 rain gauges along the bus routes. Statistical tests and public transit performance measures have been employed in this study to assess the impacts of rainy and snowy weather on the buses. The Man-Whitney test was used to identify significant changes in the median of ridership, run time, dwell time and travel time. In addition, Levene’s test was employed to capture significant changes in the variance of run time, dwell time and travel time. Moreover, six measures from four categories of public transit performance measures (schedule adherence, headway, travel time, and wait time) were used to evaluate the impacts of rainy and snowy weather on bus performance. On-time Performance, coefficient of variation of headway, service regularity, coefficient of variation of travel time, 90th-50th percentile travel time, and excess wait time were all used to determine the effect of rain and snow on bus performance. This study found that there is a negative impact of rainy and snowy weather is definite on bus performance. However, the level of impact varies by route and data groups, which suggests considering other influential factors on the performance of buses along with weather for more detailed results.
Heavy Quarkonium Production at LHC through $W$ Boson Decays

description: The production of the heavy $(c\bar{c})$-quarkonium, $(c\bar{b})$-quarkonium and $(b\bar{b})$-quarkonium states ($(Q\bar{Q'})$-quarkonium for short), via the $W^+$ semi-inclusive decays, has been systematically studied within the framework of the non-relativistic QCD. In addition to the two color-singlet $S$-wave states, we also discuss the production of the four color-singlet $P$-wave states $|(Q\bar{Q'})(^1P_1)_{\bf 1}>$ and $(Q\bar{Q'})(^3P_J)_{\bf 1}>$ (with $J=(1,2,3)$) together with the two color-octet components $|(Q\bar{Q'})(^1S_0)_{\bf 8}>$ and $|(Q\bar{Q'})(^3S_1)_{\bf 8}>$. Improved trace technology is adopted to derive the simplified analytic expressions at the amplitude level, which shall be useful for dealing with the following cascade decay channels. At the LHC with the luminosity ${\cal L}\propto 10^{34}cm^{-2}s^{-1}$ and the center-of-mass energy $\sqrt{S}=14$ TeV, sizable heavy-quarkonium events can be produced through the $W^+$ boson decays, i.e. $2.57\times10^6$ $η_c$, $2.65\times10^6$ $J/Ψ$ and $2.40\times10^6$ $P$-wave charmonium events per year can be obtained; and $1.01\times10^5$ $B_c$, $9.11\times10^4$ $B^*_c$ and $3.16\times10^4$ $P$-wave $(c\bar{b})$-quarkonium events per year can be obtained. Main theoretical uncertainties have also been discussed. By adding the uncertainties caused by the quark masses in quadrature, we obtain $Γ_{W^+\to (c\bar{c})+c\bar{s}} =524.8^{+396.3}_{-258.4}$ KeV, $Γ_{W^+\to (c\bar{b})+b\bar{s}} =13.5^{+4.73}_{-3.29}$ KeV, $Γ_{W^+\to (c\bar{b})+c\bar{c}}= 1.74^{+1.98}_{-0.73}$ KeV and $Γ_{W^+\to (b\bar{b})+c\bar{b}}= 38.6^{+13.4}_{-9.69}$ eV.

description: Hydrophobic silica aerogels with ultra-low densities have been designed and developed as cosmic dust capture media for the Tanpopo mission which is proposed to be carried out on the International Space Station. Glass particles as a simulated cosmic dust with 30 μm in diameter and 2.4 g/cm^3 in density were successfully captured by the novel aerogel at a velocity of 6 km/s. Background levels of contaminated DNA in the ultra-low density aerogel were lower than the detection limit of a polymerase chain reaction assay. These results show that the manufactured aerogel has good performance as a cosmic dust collector and sufficient quality in respect of DNA contamination. The aerogel is feasible for the biological analyses of captured cosmic dust particles in the astrobiological studies.

description: A photometric solution of an A-type W UMa binary, GSC 0763-0572 is examined with a revised orbital period. The overcontact degree is found to be $f$ = 40.66%, with a low mass ratio of $q$ = 0.2554. The result demonstrates an unambiguous increase in the orbital period with a relative period change of $ΔP\slash P = +5.69\times10^{-7} $d yr$^{-1}$. This indicates that GSC 0763-0572 is undergoing a process of mass transfer from the secondary component to the primary one with a rate of relative mass change of $Δ$$m_1$$\slash$$m$ $=+5.18\times10^{-8}$ yr$^{-1}$, for a conservative model of mass transfer. We find that GSC 0763-0572 might transform into a rapidly rotating star, if total spin angular momentum increases until it is greater than one-third of the orbital angular momentum, without breaking the contact configuration.

description: We have studied the effects of an external sinusoidal force in protein folding kinetics. The externally applied force field acts on the each amino acid residues of polypeptide chains. Our simulation results show that mean protein folding time first increases with driving frequency and then decreases passing through a maximum. With further increase of the driving frequency the mean folding time starts increasing as the noise-induced hoping event (from the denatured state to the native state) begins to experience many oscillations over the mean barrier crossing time period. Thus unlike one-dimensional barrier crossing problems, the external oscillating force field induces both \emph{stabilization or destabilization of the denatured state} of a protein. We have also studied the parametric dependence of the folding dynamics on temperature, viscosity, non-Markovian character of bath in presence of the external field.

description: The end of Muammar Gaddafi's authoritarian regime in Libya is something that should be celebrated. Gaddafi was an often brutal leader whose involvement in terrorist activities earned him enmity from many. The habits of years of largely unchallenged rule contributed to Gaddafi becoming increasingly strange during the later years of his leadership. This became most evident during his last months in office, particularly in the weeks leading up to the NATO intervention in his country, when Gaddafi's threats and rantings were both frightening and bizarre.

description: It is something of an unusual development that the opposition party in a major economic power put the global economy at risk and contributes to downgrading their own country's credit rating for little reason other than their desire to make the incumbent chief executive look bad and modestly improve their own party's chances in the national elections which are still 15 months away. The story of one of that party's leading candidates reacting to all this by holding a rally to call upon divine intervention to help his country and to mobilize his party's fundamentalist religious base, is also notable. This is, of course, the state of political affairs in the U.S. as it might be seen from Moscow, Brussels, or from Beijing, America's biggest creditor.

Environment-assisted quantum transport in ordered systems

description: Noise-assisted transport in quantum systems occurs when quantum time-evolution and decoherence conspire to produce a transport efficiency that is higher than what would be seen in either the purely quantum or purely classical cases. In disordered systems, it has been understood as the suppression of coherent quantum localisation through noise, which brings detuned quantum levels into resonance and thus facilitates transport. We report several new mechanisms of environment-assisted transport in ordered systems, in which there is no localisation to overcome and where one would naively expect that coherent transport is the fastest possible. Although we are particularly motivated by the need to understand excitonic energy transfer in photosynthetic light-harvesting complexes, our model is general---transport in a tight-binding system with dephasing, a source, and a trap---and can be expected to have wider application.

description: The phase diagram of colloidal hard superballs, of which the shape interpolates between cubes and octahedra via spheres, is determined by free-energy calculations in Monte Carlo simulations. We discover not only a stable face-centered cubic (fcc) plastic crystal phase for near-spherical particles, but also a stable body-centered cubic (bcc) plastic crystal close to the octahedron shape, and in fact even coexistence of these two plastic crystals with a substantial density gap. The plastic fcc and bcc crystals are, however, unstable in the cube and octahedron limit, suggesting that the rounded corners of superballs play an important role in stablizing the rotator phases. In addition, we observe a two-step melting phenomenon for hard octahedra, in which the Minkowski crystal melts into a metastable bcc plastic crystal before melting into the fluid phase.

Organizations like NATO were multi-lateral, but largely served the interest of the U.S. Similarly, ideas like freedom and democracy were used by the U.S. to put a more palatable face on what were otherwise proxy fights with the USSR, while the USSR used the language of peace and cooperation between nations for the same purpose.

description: We discuss the design and implementation of thin film superconducting coplanar waveguide micro- resonators for pulsed ESR experiments. The performance of the resonators with P doped Si epilayer samples is compared to waveguide resonators under equivalent conditions. The high achievable filling factor even for small sized samples and the relatively high Q-factor result in a sensitivity that is superior to that of conventional waveguide resonators, in particular to spins close to the sample surface. The peak microwave power is on the order of a few microwatts, which is compatible with measurements at ultra low temperatures. We also discuss the effect of the nonuniform microwave magnetic field on the Hahn echo power dependence.

description: Presented at the Environmental justice in the Anthropocene symposium held on April 24-25, 2017 at the Lory Student Center, Colorado State University, Fort Collins Colorado. This symposium aims to bring together academics (faculty and graduate students), independent researchers, community and movement activists, and regulatory and policy practitioners from across disciplines, research areas, perspectives, and different countries. Our overarching goal is to build on several decades of EJ research and practice to address the seemingly intractable environmental and ecological problems of this unfolding era. How can we explore EJ amongst humans and between nature and humans, within and across generations, in an age when humans dominate the landscape? How can we better understand collective human dominance without obscuring continuing power differentials and inequities within and between human societies? What institutional and governance innovations can we adopt to address existing challenges and to promote just transitions and futures?

title: A novel use for oil-contaminated drill cuttings in the manufacture of lightweight aggregate
Creators: name: Ayati, Bamdad
Publisher: name: The University of East London
Year: 2018

description: Contaminated waste drill cuttings produced from drilling activities in the North Sea is currently transported onshore and landfilled at high costs, as there is no existing option for alternative and viable recycling. The aim of this research was therefore to investigate the technical feasibility of transforming this waste into an inert, porous, ceramic material to potentially be utilised as lightweight aggregate (LWA). In this project, three samples of waste drill cuttings were obtained and characterised for chemical compositions, mineralogy, thermal behaviour and contaminant leaching. To manufacture LWA, the raw materials were dried, ball milled, formed into pellets and fired above their initial sintering temperature. The effect of firing temperature on particle density, water absorption, compressive strength and microstructure was studied and compared with those of standard commercial products such as LECA and Lytag. The mineralogy before and after firing and its effect on leaching behaviour was also investigated. Washing pre-treatments were employed to mitigate the leaching of chlorides in the manufactured LWA and the potential of milled waste glass incorporated into LWA as a matrix forming material was evaluated. Finally, the research proposed a novel approach for calculating carbon dioxide emissions for the production of drill cuttings LWA.The results of this research showed that drill cuttings contained variable amounts of minerals with poor sintering capabilities. This limited their viability to be readily used as a raw material in LWA production – due to the unfavourable physical properties and environmental compatibility of the final products. In samples with high concentrations of chloride salts, a two-step washing pre-treatment using deionised water at an L/S ratio of 10 l/kg was necessary for leaching to comply with the End of Waste criteria. In samples with high concentrations of barium sulphate and carbonate minerals, the addition of 40 wt.% waste glass in the mix and firing at 1150 °C, produced LWA with physical properties comparable to commercially available products. However, mitigating the leaching of sulphates remained a challenge in samples with high initial concentrations of drilling fluids. Carbon dioxide emissions as low as 236.0 kg per 1.0 tonne of drill cuttings LWA were estimated and compared favourably with those for current management scenarios and other waste derived LWA. Overall, the research showed that LWA manufacturing represents a beneficial reuse of drill cuttings that diverts waste from landfill.

description: The CERN-SPS accelerator has been briefly operated in a new, lower intensity neutrino mode with ~10^12 p.o.t. /pulse and with a beam structure made of four LHC-like extractions, each with a narrow width of 3 ns, separated by 524 ns. This very tightly bunched beam structure represents a substantial progress with respect to the ordinary operation of the CNGS beam, since it allows a very accurate time-of-flight measurement of neutrinos from CERN to LNGS on an event-to-event basis. The ICARUS T600 detector has collected 7 beam-associated events, consistent with the CNGS delivered neutrino flux of 2.2 10^16 p.o.t. and in agreement with the well known characteristics of neutrino events in the LAr-TPC. The time of flight difference between the speed of light and the arriving neutrino LAr-TPC events has been analysed. The result is compatible with the simultaneous arrival of all events with equal speed, the one of light. This is in a striking difference with the reported result of OPERA that claimed that high energy neutrinos from CERN should arrive at LNGS about 60 ns earlier than expected from luminal speed.

Etching of wood by glow-discharge plasma
Creators: name: Jamali, Arash
Publisher: name: University of British Columbia
Year: 2012

description: In this thesis I hypothesize that plasma will etch wood surfaces, produce new cell wall microstructures, and change the surface chemistry of wood because of differential etching of wood’s polymeric constituents. I also examine factors affecting the etching of wood by plasma, and applications of plasma etching for wood processing. Scanning electron and light microscopy and white light confocal profilometry were used to examine etching of wood surfaces. Wet chemical analysis, FTIR and XPS spectroscopy were used to analyze chemical changes at the surface of plasma-treated wood. Experiments were also performed to examine the effect of plasma treatments on the color of blue-stained wood, the morphology of fungal hyphae and the adhesion and performance of coatings on hot-oil modified wood. Exposure of wood to plasma caused etching of wood cell walls and created new surface microstructures. Regions of cell walls that were rich in lignin such as the middle lamella were etched more slowly by plasma. Confocal profilometry of wood exposed to plasma revealed a strong relationship between plasma treatment time and etching of cell walls, and same technique found that lignin pellets were etched more slowly than cellulose pellets. Plasma reduced the levels of carbohydrate at the surface of modified wood, which resulted in a relative increase in lignin content. Plasma treatment improved the effectiveness of hypochlorite bleach at removing blue-stain from wood and it prevented the discoloration of a white acrylic paint on hot-oil modified wood exposed to natural weathering. However, plasma treatment of hot-oil modified wood did not have positive effects on the adhesion and exterior performance of a range of other coatings (mainly semi-transparent stains). I conclude that prolonged exposure to plasma can etch wood cell walls, but cell wall layers that are rich in lignin are degraded more slowly. Plasma etching of wood mainly depends on treatment time and also on the structure and chemical composition of wood. Plasma treatment is an efficient pre-treatment for bleaching of blue-stained wood and reducing the discoloration of white acrylic paint on hot-oil modified wood.

description: Elastic scattering cross sections are measured for lithium atoms colliding with rare gas atoms and SF6 molecules at tunable relative velocities down to ~50 m/s. Our scattering apparatus combines a velocity-tunable molecular beam with a magneto-optic trap that provides an ultracold cloud of lithium atoms as a scattering target. Comparison with theory reveals the quantum nature of the collision dynamics in the studied regime, including both rainbows as well as orbiting resonances.
