Landau-Zener transitions in a fermionic dissipative environment
Creators: name: Chen, Ruofan
Publisher: name: arXiv
Year: 2020
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We study Landau-Zener transitions in a fermionic dissipative environment where a two-level (up and down states) system is coupled to two metallic leads kept with different chemical potentials at zero temperature. The dynamics of the system is simulated by an iterative numerically exact influence functional path integral method. In the pure Landau-Zener problem, two kinds of transition (from up to down state and from down to up state) probability are symmetric. However, this symmetry is destroyed by coupling the system to the bath. In addition, in both kinds of transitions, there exists a nonmonotonic dependence of the transition probability on the sweep velocity; meanwhile nonmonotonic dependence of the transition probability on the system-bath coupling strength is only shown in one of them. As in the spin-boson model, these phenomena can be explained by a simple phenomenological model.

description: A general model for geometric structures on differentiable manifolds is obtained by deforming infinitesimal symmetries. Specifically, this model consists of a Lie algebroid, equipped with an affine connection compatible with the Lie algebroid structure. The curvature of this connection vanishes precisely when the structure is locally symmetric. This model generalizes Cartan geometries, a substantial class, to the intransitive case. Simple examples are surveyed and corresponding local obstructions to symmetry are identified. These examples include foliations, Riemannian structures, infinitesimal G-structures, symplectic and Poisson structures.
description: Minor revision of first posting. Main changes: - "geometric structure" renamed "Cartan algebroid" - "geometric connection" renamed "Cartan connection" - Reader now directed to sequel paper "Lie algebroids and Cartan's method of equivalence" for the more substantial applications
Characterising organic and inorganic chemical signatures of water associated with shale gas extraction operations
Creators: name: Peers De Nieuwburgh, Camille
Publisher: name: Imperial College London
Year: 2019

description: During hydraulic fracturing, hydrocarbons trapped in formations flow back to the surface with water used during operations, also called “produced water”. The potential for degraded water quality in the vicinity of extraction operations thereby increases risks to public health via ingestion of contaminated groundwater. Chemical characterisation of produced water provides valuable information to manage water and preserve resources, and to treat and mitigate wastewater in future extraction operations. Currently, the lack of standard methods to quantitatively analyse produced water provides challenges for comparisons of inter-laboratory and inter-basin data. This work addresses some of the knowledge gaps associated with the characterisation of water arising from shale gas extractions operations. A combined protocol for the universal preparation of samples with organic and inorganic constituents in aqueous matrices was achieved using a solid phase extraction (SPE) C18 cartridge. The products of various shale-fluid experiments using this method indicated that in the case of produced water contamination by hydrocarbons, compounds will more likely originate from operations on site rather than from contact with the lithology. Maturation of shale is a prerequisite for hydrocarbon generation, and associated changes in shale mineral composition and the mobilisation of its trace elements could create challenges for future shale gas extraction operations, more so where acidic injection fluids are used. Therefore, careful water management practices during shale gas extraction operations are critical to avoid episodic contamination incidents. The use of fluorescence excitation emission matrix was demonstrated to be a useful portable ex-situ analysis technique to discriminate anthropogenic sources of contamination from natural signatures of water surrounding extraction operations, thereby providing a cost-efficient tool to better characterise contamination incidents during monitoring. Understanding produced water chemistry related to shale gas extraction operations is therefore essential to effectively assess and mitigate environmental and public health risks.

description: We show that quark orbital angular momentum is directly related to off-forward correlation functions which include intrinsic transverse momentum corresponding to a derivative with respect to the transverse coordinates. Its possible contribution to scattering processes is therefore of higher twist and vanishes in the forward limit. The relation of OAM to other twist 2 and 3 distributions known in the literature is derived and formalized by an unintegrated sum rule.

Is there a third-order phase transition in quenched QCD?

Year: 2005
Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: We discuss the connection between the contributions of large field configurations and the large order behavior of perturbation theory. For quenched QCD, the sensitivity of the average plaquette to a removal of large field configurations has a narrow peak near beta=5.6. Various analysis of the order 10 weak coupling series for the plaquette give robust indications for a singularity in the third derivative of the free energy (second derivative of the plaquette) with respect to beta, near beta = 5.7. We report results of numerical calculations. The peak in the third derivative of the free energy present on 4^4 lattices disappears if the size of the lattice is increased isotropically up to a 10^4 lattice. On the other hand, on 4xL^3 lattices, it persists when L increases. The location of the peak coincides with the onset of a non-zero average for the Polyakov loop and seems related to the finite temperature transition. We also discuss the discrepancy between the perturbative series and the numerical values of the plaquette.

description: We investigate the relationship of the HII region luminosity function (HII LF) to the HII region size distribution and density wave triggering in grand-design spiral galaxies. We suggest that the differential nebular size distribution is described by a power law of slope ~ -4, with flattening at radii below ~ 130 pc. This contrasts with the conventional exponential description, but it is physically and quantitatively consistent with the typical observed value of -2 for the HII LF slope. We have developed an interactive code that computes spatial isochrones for the evolving loci of spiral density waves in disk galaxies. This allows comparison of the nebular spatial distribution with the spatial isochrones for simple rotation curve parameters. Our comparisons for four grand-design galaxies suggest that the corotation radius r_co coincides with the outer ends of the star-forming arms. This value for r_co yields the best spatial correspondence between the HII regions and the isochrones, and also appears to yield a coincidence between the Inner Lindblad Resonance with the radial onset of star formation in the arms. Thus, we suggest that isochrones offer a new, simple, and effective technique for determining r_co, and thus the spiral pattern speed. However, application of the isochrones also demonstrates that evolution of the nebular population is difficult to spatially isolate in these galaxies.

description: Cereals have an important position on the agrarian market both in the Slovak Republic as well as in the world. Cereals market considerably contributes to the financial resources of producers. The market of wheat and food wheat for the period of time 1994-1996 has been analysed. The questions of sale and marketing chains of these commodities in the Slovak Republic have been considered. 1 339.3 ths.tons of wheat were sold in 1994, 1 444.4 ths.tons in 1995 and 1112.6 ths.tons in 1996. The most productive area is the western part of Slovakia that produces 68 % of total production. Market of food wheat has an increasing tendency, in 1994 it accounted for 35% and in 1996 50.6%. The food wheat price does not correspond to the prices in the EU. The state intervention purchase of food wheat is realized for a minimum guarantee price, that is 3 630 Sk per 1 ton. The requirements of producers as well as autonomous institutions in agriculture are about 4 300 - 4 800 Sk per 1 ton.

description: Microservices architectures allow for short deployment cycles and immediate effects but offer no safety mechanisms when service contracts need to be changed. Maintaining the soundness of microservice architectures is an error-prone task that is only accessible to the most disciplined development teams. We present a microservice management system that statically verifies service interfaces and supports the seamless evolution of compatible interfaces. We define a compatibility relation that captures real evolution patterns and embodies known good practices on the evolution of interfaces. Namely, we allow for the addition, removal, and renaming of data fields of a producer module without breaking or needing to upgrade consumer services. The evolution of interfaces is supported by runtime generated proxy components that dynamically adapt data exchanged between services to match with the statically checked service code.The model was instantiated in a core language whose semantics is defined by a labeled transition system and a type system that prevents breaking changes from being deployed. Standard soundness results for the core language entail the existence of adapters, hence the absence of adaptation errors and the correctness of the management model. This adaptive approach allows for gradual deployment of modules, without halting the whole system and avoiding losing or misinterpreting data exchanged between system nodes. Experimental data shows that an average of 69% of deployments that would require adaptation and recompilation are safe under our approach.

description: The N terminal domain (NTD) of Nucleocapsid protein (N protein) of coronavirus (CoV) binds to the viral (+) sense RNA and results in CoV ribonucleoprotien (CoV RNP) complex, essential for the virus replication. In this study, the RNA-binding N terminal domain (NTD) of the N protein was targeted for the identification of possible inhibitors of RNA binding. Two NTD structures of N proteins were selected (2OFZ and 1SSK, 92% homology) for virtual screening of 56,079 compounds from Asinex and Maybridge library to identify top 15 hits for each of the targets based on “docking score”. These top-hits were further screened for MM-GBSA binding free energy, pharmacokinetic properties (QikProp) and drug-likeness (SwissADME) and subjected to molecular dynamics (MD) studies. Two suitable binders (ZINC00003118440 and ZINC0000146942) against the target 2OFZ were identified. ZINC00003118440 is a theophylline derivative under the drug class ‘bronchodilEtors’ and further screening with approved bronchodilators was also studied to identify their ability to bind to the RNA binding region on the N protein. The other identified top hit is ZINC0000146942, which is a 3,4dihydropyrimidone class molecule. Hence this study suggests two important class of compounds, theophylline and pyrimidone derivaties as possible inhibitors of RNA binding to the N terminal domain of N protein of coronavirus, thus opening new avenues for in vitro validations.

description: A dimensionally reduced expression for the QCD fermion determinant at finite temperature and chemical potential is derived which sheds light on the determinant's dependence on these quantities. This is done via a partial zeta regularisation, formally applying a general formula for the zeta-determinant of a differential operator in one variable with operator-valued coefficients. The resulting expression generalises the known one for the free fermion determinant, obtained via Matsubara frequency summation, to the case of general background gauge field; moreover there is no undetermined overall factor. Rigorous versions of this result are obtained in a continuous time--lattice space setting. The determinant expression reduces to a remarkably simple form in the low temperature limit. A program for how to use this to obtain insight into the QCD phase transition at zero temperature and nonzero density is outlined.

description: This paper presents a novel simplified approach for determining the fundamental vibration characteristics of reinforced concrete (RC) buildings for application in the seismic retrofitting of substandard multi-storey RC building structures. Even when retrofitted, such structures would likely respond inelastically under a major earthquake, where the seismic response is most realistically represented by computationally expensive nonlinear dynamic analysis. Towards reducing such computational demands, the capacity spectrum method (CSM) offers a practical design and assessment approach which utilises nonlinear static pushover analysis in conjunction with the dynamic characteristics of a structure to establish whether the seismic capacity of the structure meets the demands of seismic ground motion. In this respect, the dynamic characteristics of a structure can be ordinarily obtained by performing conventional direct modal analysis which requires the assembly of mass and stiffness matrices to solve the eigenvalue problem. This paper presents the development of a simplified numerical approach that determines the translational modes of vibration and the associated periods for a retrofitted building structure in both horizontal directions in a simplistic manner without assembling the mass and stiffness matrices. The accuracy of the proposed simplified approach is verified for realistic structures via comparisons against direct eigenvalue analysis. This, along with planned research on simplified pushover analysis, paves the way for the practical seismic retrofitting of substandard reinforced concrete buildings within the CSM framework.

description: The high mechanical strength and superior physical properties of graphene and its derivatives have made them an ideal choice for modern engineering structures. The use of graphene as nanofillers in reinforced polymer composites has led to the development of sustainable high performance composite materials. Such materials can be utilized in engineering structures not only to improve their structural performance but also to reduce their environmental impact as well. Skew plates are commonly used in aerospace structures and ship hulls. In this paper, a size-dependent nonlinear model is presented for bending analysis of composite laminated micro skew plates reinforced with functionally graded graphene sheets. The modified Halpin-Tsai micromechanical model and rule of mixture are considered for the effective mechanical properties of graphene sheets which vary continuously throughout the thickness of the skew plate. The Schapery's model is considered for the effective thermal properties. The skew plate is assumed in thermal environments while transversely loaded. The governing equations of the problem are derived based on the Mindlin plate theory and the modified coupled stress theory. Using the generalised differential quadrature method, the nonlinear governing equations are first converted into a set of linear algebraic equations and then solved to obtain the bending moment of the skew plate under different loading conditions. Results show that reinforcing composite laminated micro skew plates with functionally graded graphene sheets increases the overall stiffness and bending strength of the plate, enhancing its performance under large deflections. It has also been observed that the bending performance of the skew plate further enhances through changing the distribution pattern of the functionally graded graphene reinforcement as well as with an increase in the angle of the skew plate.

description: Developing web applications requires dealing with their distributed nature and the natural asynchronicity of user input and network communication. For facilitating this, different researchers have explored the combination of a multi-tier programming language and functional reactive programming. However, existing proposals take this approach only part of the way (some parts of the application remain imperative) or remain naive, with no regard for avoiding glitches across network communication, network traffic overhead, compatibility with common APIs like XMLHttpRequest etc. In this paper, we present Gavial: the first mature design and implementation of multi-tier FRP that allows constructing an entire web application as a functionally reactive program. By applying a number of new ideas, we demonstrate that multi-tier FRP can in fact deal realistically with important practical aspects of building web applications. At the same time, we retain the declarative nature of FRP, where behaviors and events have an intuitive, compositional semantics and a clear dependency structure.

description: The pressure-volume relationship and the zone-center optical phonon frequency of cubic diamond at pressures up to 600 GPa have been calculated based on Density Functional Theory within the Local Density Approximation and the Generalized Gradient Approximation. Three different approaches, viz. a pseudopotential method applied in the basis of plane waves, an all-electron method relying on Augmented Plane Waves plus Local Orbitals, and an intermediate approach implemented in the basis of Projector Augmented Waves have been used. All these methods and approximations yield consistent results for the pressure derivative of the bulk modulus and the volume dependence of the mode Grueneisen parameter of diamond. The results are at variance with recent precise measurements up to 140 GPa. Possible implications for the experimental pressure determination based on the ruby luminescence method are discussed.

description: Scenario 7’s objective in the UBC Food System Project is to increase education, awareness, participation and effectiveness in composting on campus. In September 2004, the In-Vessel Composting Facility was created by UBCWaste Management (UBCWM) as a large-scale composting practice on campus. In the fall of 2006, UBCWM launched the organic waste composting program through collaboration with UBC Food Services (UBCFS) and Wastefree UBC. The goal of this research project was to conduct a critical review of the “Get Caught Composting Campaign” (GCCC), an initiative created by our former AGSC 450 colleagues from spring 2006, in order to evaluate its effectiveness and increase its awareness on campus. Through literature reviews, we found that the greatest challenges the In-Vessel Composting program has faced are lack of awareness and contamination of the compost bins; and that the most effective way to increase the awareness of the GCCC is through social marketing techniques. We conducted a thorough analysis of the campaign by campus awareness surveys to determine if people knew about the GCCC and how they felt about it, by volunteer questionnaires, and by data analysis of the Caught Composting 2007 Tally Sheet to find out how the campaign was actually implemented. Based on the information we obtained from the research, we found that there is still potential for the GCCC to be a successful initiative, and have thus created various recommendations for UBCWM, UBCFS, and future AGSC 450 colleagues to consider and apply in the future.

description: Der Kosovo steht derzeit vor der Herausforderung, tausende aus Westeuropa zurückgekehrte Migranten zu integrieren. Viele von ihnen hatten das Land im Winter 2014/15 in Scharen verlassen. Diskutiert wurde dieser ‚Exodus‘ im IAMO Policy Brief 24. Steigende Asylbewerberzahlen in den Zielländern führten zu einer Verschärfung der Asylpolitik, in deren Folge in den Jahren 2015 und 2016 mehr als 20.000 Personen in den Kosovo zurückgekehrt sind. Im Rahmen einer empirischen Befragung, die sich mit den Chancen und Problemen einer erfolgreichen Reintegration befasste, wurden Gespräche mit 179 dieser Rückkehrer geführt. Neben einem eher geringem Bildungsstand und geringer Qualifikation der Rückkehrer, wird die Wiedereingliederung vor allem durch die generell sehr schlechte Lage auf dem Arbeitsmarkt behindert. Erschwerend hinzu kommt eine zum Teil erhebliche psychische Belastung aufgrund der schwierigen, für einige Migranten sogar traumatisierenden Erfahrung von Migration und unfreiwilliger Rückkehr. Es ergibt sich die Gefahr eines Teufelskreises, bei dem auf die unfreiwillige Rückkehr Probleme bei der Reintegration folgen, welche dann wiederum in einem erneuten Wunsch nach Abwanderung münden. Die Ergebnisse der Studie weisen in der Tat auf eine geringe Bleibeintention unter den Rückkehrern hin.

description: Kosovo currently faces the challenge of reintegrating thousands of returned migrants who left the country in 2014 /2015. This migration wave was discussed in the IAMO Policy Brief 24. After facing restrictive asylum policies in the destination countries in Western Europe, more than 20,000 people returned to Kosovo in 2015 and 2016. Based on the results of an empirical survey of around 180 returnees, this policy brief discusses a number of reintegration issues. In addition to low levels of education and skills, reintegration is impeded above all by the precarious state of Kosovo’s labour market. This is compounded by a psychological burden that often arises from the sometimes traumatic experience of migration and involuntary return. The migration of Kosovars is at risk of becoming a vicious cycle composed of involuntary return and problems reintegrating, resulting in a further attempt at migration. Indeed, the results of the study show that many returnees do not intend to remain in Kosovo.
Foundations of a live data exploration environment

description: Context: A growing amount of code is written to explore and analyze data, often by data analysts who do not have a traditional background in programming, for example by journalists. Inquiry: The way such data anlysts write code is different from the way software engineers do so. They use few abstractions, work interactively and rely heavily on external libraries. We aim to capture this way of working and build a programming environment that makes data exploration easier by providing instant live feedback. Approach: We combine theoretical and applied approach. We present the \emph{data exploration calculus}, a formal language that captures the structure of code written by data analysts. We then implement a data exploration environment that evaluates code instantly during editing and shows previews of the results. Knowledge: We formally describe an algorithm for providing instant previews for the data exploration calculus that allows the user to modify code in an unrestricted way in a text editor. Supporting interactive editing is tricky as any edit can change the structure of code and fully recomputing the output would be too expensive. Grounding: We prove that our algorithm is correct and that it reuses previous results when updating previews after a number of common code edit operations. We also illustrate the practicality of our approach with an empirical evaluation and a case study. Importance: As data analysis becomes an ever more important use of programming, research on programming languages and tools needs to consider new kinds of programming workflows appropriate for those domains and conceive new kinds of tools that can support them. The present paper is one step in this important direction.

title: Corporate Governance in Africa: The Role and Performance of Board of Directors. Myth and Reality. The Cameroon Evidence
Creators: name: Areneke, Geofry Nfortaw Agbor

description: Grounded on a multi-theoretic approach, the purpose of this study was to investigate and examine the role and performance of board of directors in corporate governance in Cameroon. The study was motivated by the absence of rigorous corporate governance studies aimed at understanding the role of boards in an African context. The study adopted an exploratory research design in which data was collected through questionnaire survey and analysed quantitative. A qualitative follow up on the quantitative findings to provide a robust explanation was conducted. The findings suggest that, boards in Cameroon perform multiple roles as identified-by the various theories of corporate governance. However, board resource or networking was highlighted to be the most important role boards in Cameroon are committed to perform. This was followed by strategic control, behavioural control, strategic participation, output control, and stakeholder task respectively. Results pointed to the fact that, board roles depending on how it is executed does affect performance of firms. Boards that perform various roles have a positive effect on firm performance while boards that are majority shareholder oriented have a negative effect on the firm’s performance. It also emerged that corporate governance is perceived differently within various industries in Cameroon. Findings also suggest CG practices in Cameroon are very much nascent. The study recommends that corporate governance in Cameroon should be made very visible by implementing separate corporate governance impetus geared at ensuring accountability and transparency in the way firms operate. It also recommends the protection of minority shareholders in firms where there exists concentrated ownership. Finally the study recommends owners of firms to hire directors who understand risk so that; while they control management, they can effectively and efficiently contribute towards firm’s strategy and direction to enhance firm performance.

description: We calculate the two-pion correlation function for an expanding hadron source with a finite baryon density. The space-time evolution of the source is described by relativistic hydrodynamics and the Hanbury-Brown-Twiss (HBT) radius is extracted after effects of collective expansion and multiple scattering on the HBT interferometry have been taken into account, using quantum probability amplitudes in a path-integral formalism. We find that this radius is substantially smaller than the HBT radius extracted from the freeze-out configuration.

description: The UBC Food System Project seeks to increase sustainability of the UBC food system. Specifically, our task in helping reach that goal was to propose mechanisms aimed at incorporating UBC Farm produce into a campus Alma Mater Society (AMS) food outlet, Bernoulli’s Bagels. In considering implementation of such mechanisms, AMS produce procurement and volume requirements were examined. UBC Farm produce availability and price as well as consumer support were also evaluated in assessing the feasibility of incorporating UBC Farm produce into the existing menu at Bernoulli’s Bagels. Subsequently, we proposed a seasonal, Rosemary Butternut Squash Bagel special, which would run from September 17th, 2007 to October 12th, 2007 thereby encompassing a time of maximum sales volume for this food outlet. The ingredients for this special were chosen for their relative abundance and availability during this time from the UBC Farm. Our consumer support survey indicated that consumers would be more willing to purchase such a bagel special if ingredients were locally and sustainably produced by UBC Farm, highlighting the necessity for promotional and educational materials to be developed around this topic. Therefore, we developed a marketing strategy to educate staff and consumers about the existence and practices of UBC Farm, as well as the importance of sustainability and eating locally, organically produced food. Our strategy consisted of a promotional poster, an educational pamphlet for consumers and a frequently asked question sheet to aid staff in delivering this message. As many more seasonal specials and promotional opportunities exist that would enhance the overall sustainability of the UBC food system, we also developed an extensive list of recommendations for our future colleagues.

title: How to Make the Most Productive Intervention in a Complex Economic System
Creators: name: Madsen, Björn
Publisher: name: The Open University
Year: 2015

description: Information about supply and demand propagates through supply chains in a queueing network with people and computers as batch information processors. As each batch processor delays propagation of information whilst pursuing optimal local decisions, the effect is delay and distortion of the information that is used to commit resources to actions in the supply chain. This thesis investigates the effect of delay and imperfect information as a source of error, to establish the case for change in research focus from optimal exploitation of physical constraints to optimal exploitation of information. In the context of real world supply chains, the thesis asks "How does one make the most productive intervention in a complex economic system?" and pursues a meta-intervention which perpetually minimises the discovered error-term. Evidence from literature indicates that agent-based modelling permits real-time peer-to-peer communication and distributed optimisation. Based on the literature the research project designs and develops an agent-based model which operates in real-time without batch-processes and can perform incremental multi-objective optimisation under realistic (chronologically progressive) conditions for decision making. The agent based model is then used to investigate two real-world supply chains, as case studies, which reveals a significant improvement of profitability and order-fulfilment. The thesis concludes that agent-based modelling is a very promising direction for "making the most productive intervention" as it reduces delay to a minimum. Finally it recommends that continuous improvement of decision making methods is a role better suited for humans, rather than operational decision making where computers cope much better with the high amount of detailed information.

description: Paulownia witches’ broom (PaWB) is caused by phytoplasma of Aster Yellows group, and resulted in severe damage to the growth and premature death of the infected tree. In vitro cultures of meristems are important tools for solving problems with plant diseases. In recent study meristem cultures from phytoplasma infected Paulownia tomentosa have been created in an attempt to obtain healthy plants. The faster procedure with longer explants generated 95% regeneration but no healthy plants. The combination of smaller explants and thermotherapy resulted in the generation of plantlets with a healthy phenotype. The PCR analyzes showed the absence of phytoplasma only in one of the produced plants. Despite the low efficiency, expressed in one phytoplasma-free regenerant of a total of 480 explants, these results can serve to continue the work on optimizing the used strategy.

description: With increasing global agrifood trade, private food standards and certifications have proliferated. Yet, their trade effects remain ambiguous. We provide further empirical evidence by assessing the effect of GlobalGAP certification on agrifood exports to high-value markets in EU and OECD countries. Empirically, we estimate a structural gravity model—that accounts for zero trade and endogeneity of certification—using a novel dataset of certified producers and land area cultivated to apples, bananas, and grapes from 2010 to 2015. While our results generally confirm the trade-enhancing effect of GlobalGAP certification for both developed and developing countries, we show that the effects vary across products.
