description: We present first-principles calculations on electron transport through Na nanowires at finite bias voltages. The nanowire exhibits a nonlinear current-voltage characteristic and negative differential conductance. The latter is explained by the drastic suppression of the transmission peaks which is attributed to the electron transportability of the negatively biased plinth attached to the end of the nanowire. In addition, the finding that a voltage drop preferentially occurs on the negatively biased side of the nanowire is discussed in relation to the electronic structure and conduction.

description: Sustainable intensification and climate-smart agriculture initiatives promote complex systems-based innovations to simultaneously improve yields and conserve natural resources. These innovations are usually tested under near-perfect experimental conditions with purposively selected farmers. Using a quasi-experimental approach and geographic information system, we evaluate a systems-based sustainable intensification project in Malawi aiming at improving whole-farm productivity and nutrition through integrated agricultural innovations. We find adopters of these innovations to systematically differ from non-adopters and suggestive evidence of potential systematic targeting of project locations and households. Econometric results using efficient influence function and propensity score matching methods show consistently higher maize yield and value of harvest, on average and across quantiles, for project beneficiaries, compared to that of randomly selected non-beneficiary households in non-target villages. Our findings highlight the need to rethink selection criteria for systems-based innovations, something that could potentially bear severe implications upon scaling up.

description: Das Phänomen Chemsex – gezielter Substanzkonsum im sexuellen Kontext von Männern, die Sex mit Männern haben. In der vorliegenden Arbeit wird untersucht, wie sich der Substanzkonsum auf das sexuelle Erleben und die Sexualität ohne Substanzen auswirkt und aus welchen Motiven Chemsex praktiziert wird. Mithilfe semistrukturierter Interviews mit Männern, die Chemsex praktizieren oder praktiziert haben, werden diese Fragen beleuchtet. Aufgrund der hohen Risikofaktoren dieses Phänomens wird ebenfalls auf entsprechende Anlaufstellen Bezug genommen. Der Substanzkonsum intensiviert das sexuelle Verlangen und die Wahrnehmung. Durch den Konsum hochpotenter Drogen wird eine Unterscheidung zwischen sexuellem Erleben und Rauscherleben unmöglich. Die Aussagen der Probanden zeigen eine hohe Übereinstimmung und wenig Varietät. Die Sexualität ohne Substanzen wird als langweilig und nicht erfüllend wahrgenommen. Eine Sensibilisierung für Chemsex bei Fachpersonen ist notwendig; es sollte ein Raum für Aufklärung, Gespräche und Fragen geschaffen werden.

description: This paper examines the agllomeration hypothesis: i.e., firm productive efficiency is increased by closer proximity to other firms. Using a stochastic input distant function with heteroskedastic inefficiency effects, we find that the density of Ontario dairy farms has a significant positive economic effect on production efficiency. The finding has implications for understanding agricultural firm location and farmer led efforts to preserve agricultural farming activities in some regions.

description: In this paper, the sparse sensor placement problem for least-squares estimation is considered, and the previous novel approach of the sparse sensor selection algorithm is extended. The maximization of the determinant of the matrix which appears in pseudo-inverse matrix operations is employed as an objective function of the problem in the present extended approach. The procedure for the maximization of the determinant of the corresponding matrix is proved to be mathematically the same as that of the previously proposed QR method when the number of sensors is less than that of state variables (undersampling). On the other hand, the authors have developed a new algorithm for when the number of sensors is greater than that of state variables (oversampling). Then, a unified formulation of the two algorithms is derived, and the lower bound of the objective function given by this algorithm is shown using the monotone submodularity of the objective function. The effectiveness of the proposed algorithm on the problem using real datasets is demonstrated by comparing with the results of other algorithms. The numerical results show that the proposed algorithm improves the estimation error by approximately 10% compared with the conventional methods in the oversampling case, where the estimation error is defined as the ratio of the difference between the reconstructed data and the full observation data to the full observation. For the NOAA-SST sensor problem, which has more than ten thousand sensor candidate points, the proposed algorithm selects the sensor positions in few seconds, which required several hours with the other algorithms in the oversampling case on a 3.40 GHz computer.

Konkret stellt sich die die Frage, unter welchen Umständen ein Arbeitnehmer seinen Anspruch auf Lohnzahlung trotz Nichterbringung der Arbeitsleistung behält. Anhand ausgewählter, in der arbeitsrechtlichen Praxis häufig vorkommenden Fallgruppen, werden neben den Voraussetzungen insbesondere auch resultierende Rechtsfolgen hinsicht-lich des Vergütungsanspruches dargelegt. Das Fundament dieser Ausführungen bilden die gesetzlichen Regelungen. Für deren rechtliche Auslegung, wird sowohl auf die bisherige Rechtsprechung als auch auf juristische Meinungen in der Literatur zurückgegriffen. Im Ergebnis schafft die vorliegende Arbeit Klarheit zu den arbeitsrechtlichen Regelungen be-züglich der Durchbrechung des synallagmatischen Grundsatzes und untersucht auf Grundlage dessen, inwiefern die Anspruchserhaltungsnormen auf konkrete Auswirkungen der gegenwärtig nach wie vor herrschenden Corona-Pandemie (Covid-19) angewendet werden können.
Quantum information vs.\ epistemic logic: An analysis of the Frauchiger-Renner theorem
Creators: name: Boge, Florian J.
Publisher: name: arXiv
Year: 2019
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A recent no-go theorem (Frauchiger and Renner, 2018) establishes a contradiction from a specific application of quantum theory to a multi-agent setting. The proof of this theorem relies heavily on notions such as 'knows' or `is certain that'. This has stimulated an analysis of the theorem by Nurgalieva and del Rio (2018), in which they claim that it shows the "[i]nadequacy of modal logic in quantum settings" (ibid.). In this paper, we will offer a significantly extended and refined reconstruction of the theorem in multi-agent modal logic. We will then show that a thorough reconstruction of the proof as given by Frauchiger and Renner requires the reflexivity of access relations (system $\mathsf{\mathbf{T}}$). However, a stronger theorem is possible that already follows in serial frames, and hence also holds in systems of \emph{doxastic} logic (such as $\mathsf{\mathbf{KD45}}$). After proving this, we will discuss the general implications for different interpretations of quantum probabilities as well as several options for dealing with the result.

description: In this paper, we consider the problem of verifying safety constraint satisfaction for single-input single-output systems with uncertain transfer function coefficients. We propose a new type of barrier function based on a vector norm. This type of barrier function has a measurable upper bound without full state availability. An identifier-based estimator allows an exact bound for the uncertainty-based component of the barrier function estimate. Assuming that the system is safe initially allows an exponentially decreasing bound on the error due to the estimator transient. Barrier function and estimator synthesis is proposed as two convex sub-problems, exploiting linear matrix inequalities. The barrier function controller combination is then used to construct a safety backup controller. And we demonstrate the system in a simulation of a 1 degree-of-freedom human-exoskeleton interaction.

description: In a recent paper we have suggested that a formulation of quantum mechanics should exist, which does not require the concept of time, and that the appropriate mathematical language for such a formulation is noncommutative differential geometry. In the present paper we discuss this formulation for the free point particle, by introducing a commutation relation for a set of noncommuting coordinates. The sought for background independent quantum mechanics is derived from this commutation relation for the coordinates. We propose that the basic equations are invariant under automorphisms which map one set of coordinates to another- this is a natural generalization of diffeomorphism invariance when one makes a transition to noncommutative geometry. The background independent description becomes equivalent to standard quantum mechanics if a spacetime manifold exists, because of the proposed automorphism invariance. The suggested basic equations also give a quantum gravitational description of the free particle.

description: The study attempted to measure and compare resource use and productivity with respect to farm size and tenancy in an area of Bangladesh. It used empirical data collected through a lengthy intensive farm survey. It was observed that productivity per acre increased up to certain level (about 4.0 acres) then decreased as the farm size increased. Medium farms (2.0 - 3.99 acres) were found relatively more productive than small farms (below 2.0 acres) and large farms (4.0 acres and above). Share cropping tenancy was found to be inefficient in resource use and production, but cost-sharing tenancy had some favourable impact toward improving productivity on sharecropped land.

description: Establishing dense correspondences between a pair of images is an important and general problem, covering geometric matching, optical flow and semantic correspondences. While these applications share fundamental challenges, such as large displacements, pixel-accuracy, and appearance changes, they are currently addressed with specialized network architectures, designed for only one particular task. This severely limits the generalization capabilities of such networks to new scenarios, where e.g. robustness to larger displacements or higher accuracy is required. In this work, we propose a universal network architecture that is directly applicable to all the aforementioned dense correspondence problems. We achieve both high accuracy and robustness to large displacements by investigating the combined use of global and local correlation layers. We further propose an adaptive resolution strategy, allowing our network to operate on virtually any input image resolution. The proposed GLU-Net achieves state-of-the-art performance for geometric and semantic matching as well as optical flow, when using the same network and weights.

description: Biomedical data analysis has been playing an important role in healthcare provision services. For decades, medical practitioners and researchers have been extracting and analyse biomedical data to derive different health-related information. Recently, there has been a significant rise in the amount of biomedical data collection. This is due to the availability of biomedical devices for the extraction of biomedical data which are more portable, easy to use and affordable, as an effect technology advancement. As the amount of biomedical data produced every day increases, the risk of human making analytical and diagnostic mistakes also increases. For example, there are approximately 40 million diagnostic errors involving medical imaging annually worldwide, hence rise a need for the development of fast, accurate, reliable and automatic means for analysis of biomedical data. Conventional machine learning has been used to assist in the analysis and interpretation of biomedical data automatically, but always limited with the need for feature extraction process to train the built models. To achieve this, three studies have been conducted. Two studies were conducted by using EEG signals and one study by using microscopic images of cancer cells. In the first study with EEG signals, our method managed to interpret motor imaginary activities from a 64 channels EEG device with 99% classification accuracy when all the 64 channels were used and 91.5% classification when the number of channels was selected to eight (8) channels. In a second study which involved steady-state visual evoked potential form of EEG signals, our method achieved an average of 94% classification accuracy by using two channels, skin like EEG sensor. In the third study for authentication of cancer cell lines by using microscopic images, our method managed to attain an average of 0.91 F1-score in the authentication of eight classes of cancer cell lines. Studies reported in this thesis, significantly shows that CNN can play a major role in the development of a computerised way in the analysis of biomedical data. Towards provision of better healthcare by using CNN in analysis of different formats of biomedical data, this thesis has three major contributions, i) introduction of a new method for EEG channels selection towards development of portable EEG sensors for real-life application, and ii) introduction of a method for cancer cell lines authentication in the laboratory environment towards development of anti-cancer drugs, and iii) Introduction of a method for authentication of isogenic cancer cell lines.

description: The lowest (``vector'') and next-lowest (``scalar'') bound-state masses of the massive Schwinger model have been determined recently to a very high accuracy numerically on the lattice. Therefore, improved results for these bound-state masses from analytical calculations are of some interest. Here, we provide such improved results by employing both standard and renormal-ordered (fermion) mass perturbation theory, as well as a consistency condition between the two perturbative calculations. The resulting bound-state masses are in excellent agreement with the lattice results for small and intermediate fermion mass, and remain within 10% of the exact results even in the limit of very large fermion mass.

description: The modulational instability (MI) of plane waves in nonlocal Kerr media is studied for a general, localized, response function. It is shown that there always exists a finite number of well-separated MI gain bands, with each of them characterised by a unique maximal growth rate. This is a general property and is demonstrated here for the Gaussian, exponential, and rectangular response functions. In case of a focusing nonlinearity it is shown that although the nonlocality tends to suppress MI, it can never remove it completely, irrespectively of the particular shape of the response function. For a defocusing nonlinearity the stability properties depend sensitively on the profile of the response function. It is shown that plane waves are always stable for response functions with a positive-definite spectrum, such as Gaussians and exponentials. On the other hand, response functions whose spectra change sign (e.g., rectangular) will lead to MI in the high wavenumber regime, provided the typical length scale of the response function exceeds a certain threshold. Finally, we address the case of generalized multi-component response functions consisting of a weighted sum of N response functions with known properties.

LAND TENURE AND EFFICIENCY IN BORO RICE PRODUCUON IN AN AREA OF MYMENSINGH DISTRICT

description: This paper examines the relative efficiency of the alternative forms of land tenure in irrigated boro rice production with a sample of 124 farms. Inter-tenure comparison revealed that there were no major differences in resource use and yield among the specified tenure groups. However, owner-tenant farms obtained highest yield, gross and net return per acre while yield of crop, gross and net return per acre were lowest for the pure tenant farms. Comparative analysis of the owned and rented components of the same owner-tenant farms revealed that they used more of all the inputs and obtained higher yield on owned land than on rented land. Thus the evidence lend support to the Marshallian proposition that share tenancy results in under-utilization of resources and hence is an inefficient form of tenure arrangement.
title: "We are fine here": Ngäbe Perspectives on Urban Living, Poverty, and Well-being in Bocas del Toro, Panama
Creators: name: Visser, Diana Boana
Publisher: name: University of Kent
Year: 2021

description: This dissertation explores urban indigenous notions of poverty and living well among Ngäbe residents of Bocas del Toro, Panama. I examine how these notions relate to Ngäbe urban living conditions and their endeavours to live well in the urban environment. Based on 16 months of ethnographic research among indigenous families in the mangrove neighbourhood of La Solución, I demonstrate that Ngäbe ideals of how to live well are based on indigenous notions of generosity, cooperation, hard work, and autonomy. The act of cultivating vegetables, in particular, embodies the values that underpin Ngäbe visions of the proper way to live and of what constitutes a good life. In the urban environment where cultivation is not possible, Ngäbe individuals express the ideals imbued in cultivation practices by emphasising household autonomy, by cooperating and sharing with neighbours, and by nostalgically invoking the finca (farmland) and the way of life it allows. My research contributes to the anthropology of indigenous urbanisation by analysing how urban Ngäbe residents' notions of poverty and living well shape and are shaped by their experiences and inter-ethnic encounters in the urban environment. As I demonstrate in this thesis, hierarchical inter-ethnic relations and discriminatory political approaches engender experiences of precarity, discrimination, and marginalisation among urban Ngäbe residents. These experiences challenge Ngäbe residents in their abilities to live well. Yet, while urban Ngäbe households are commonly reported to live in conditions of poverty, Ngäbe individuals themselves often reject the idea that this is the case. Although urban Ngäbe residents often lament about the urban inconveniences and challenges they face, they largely focus on their personal responsibility and endeavours to live well within their given circumstances. My ethnographic narrative offers an engagement with indigenous Ngäbe voices and perspectives that is often missing from government assessments of urban indigenous living conditions. I provide an account that prioritises local experiences and the political and social processes that structure local livelihoods. This perspective from the grassroots illustrates how conditions and understandings of poverty are socially and politically generated. In this respect, my dissertation contributes to key debates in development and post-development theory. I argue that an externally imposed identification of Ngäbe as poor disregards indigenous perspectives and masks the unequal power structures and political approaches that create their adverse conditions.

description: In samples used to maintain the US resistance standard the breakdown of the dissipationless integer quantum Hall effect occurs as a series of dissipative voltage steps. A mechanism for this type of breakdown is proposed, based on the generation of magneto-excitons when the quantum Hall fluid flows past an ionised impurity above a critical velocity. The calculated generation rate gives a voltage step height in good agreement with measurements on both electron and hole gases. We also compare this model to a hydrodynamic description of breakdown.

description: A sample survey was conducted in two villages in the district of Mymensingh with the objective of identifying the major causes and effects of land transfer. The major findings are that the trend of distress sales of land, mainly crop land has been increasing and that large farmers and businessmen are buying land. A significant proportion of sellers have become completely landless within a few years, some became tenants, some lost their draft animals as well and most sellers have too many people in the family to work on too little land left after selling.

description: We discuss the action of SL(2,Z) on local operators in D=4, N=4 SYM theory in the superconformal phase. The modular property of the operator's scaling dimension determines whether the operator transforms as a singlet, or covariantly, as part of a finite or infinite dimensional multiplet under the SL(2,Z) action. As an example, we argue that operators in the Konishi multiplet transform as part of a (p,q) PSL(2,Z) multiplet. We also comment on the non-perturbative local operators dual to the Konishi multiplet.

description: The social tradition of Bangladesh has not favoured women workers. Their work in the home has been considered as unproductive by male dominated society. Their position was well-stated by the Secretariat of the Copenhagen Conference of 86 governments called to review the UN Decade of Women : "Throughout the developing world, a major problem is that women's work is often invisible. Her work, though vital to the task of meeting the daily needs of the family, goes unrecorded, unsupported and unrewarded" (Anonymous 1980). Women themselves have accepted their position unquestioningly. "The vast majority of our women suffer from deep-rooted inferiority complex. From their childhood they grow up to regard themselves as inferior beings, and are content to accept the subordinate position assigned to them by their family and society" (Jahan 1975). Rural poverty among the landless and near landless is forcing women to come out of the home and work, and to come to the cities as housemaids, brickbreakers, construction workers or to work at other low-status and low-wage jobs. The famine of 1974 was especially instrumental in drawing women, often deserted by their husbands, to seek survival for themselves and their children by working in Dacca city. This study exposes the life situations of those who bear simultaneously the double burden of womanhood and poverty.
title: Using Particle Swarm Optimization for Market Timing Strategies

description: Market timing is the issue of deciding when to buy or sell a given asset on the market. As one of the core issues of algorithmic trading systems, designers of such system have turned to computational intelligence methods to aid them in this task. In this thesis, we explore the use of Particle Swarm Optimization (PSO) within the domain of market timing.nPSO is a search metaheuristic that was first introduced in 1995 [28] and is based on the behavior of birds in flight. Since its inception, the PSO metaheuristic has seen extensions to adapt it to a variety of problems including single objective optimization, multiobjective optimization, niching and dynamic optimization problems. Although popular in other domains, PSO has seen limited application to the issue of market timing. The current incumbent algorithm within the market timing domain is Genetic Algorithms (GA), based on the volume of publications as noted in [40] and [84]. In this thesis, we use PSO to compose market timing strategies using technical analysis indicators. Our first contribution is to use a formulation that considers both the selection of components and the tuning of their parameters in a simultaneous manner, and approach market timing as a single objective optimization problem. Current approaches only considers one of those aspects at a time: either selecting from a set of components with fixed values for their parameters or tuning the parameters of a preset selection of components. Our second contribution is proposing a novel training and testing methodology that explicitly exposes candidate market timing strategies to numerous price trends to reduce the likelihood of overfitting to a particular trend and give a better approximation of performance under various market conditions. Our final contribution is to consider market timing as a multiobjective optimization problem, optimizing five financial metrics and comparing the performance of our PSO variants against a well established multiobjective optimization algorithm. These algorithms address unexplored research areas in the context of PSO algorithms to the best of our knowledge, and are therefore original contributions. The computational results over a range of datasets shows that the proposed PSO algorithms are competitive to GAs using the same formulation. Additionally, the multiobjective variant of our PSO algorithm achieve statistically significant improvements over NSGA-II.

description: Die vorliegende Bachelorarbeit befasst sich mit der Erschließung von Möglichkeiten und Grenzen des agilen Managements in einem Kulturbetrieb. Zu diesem Zweck wurde der Orchesterbetrieb als Form eines Kulturbetriebs gewählt. Für das agile Management werden bestimmte Aspekte und Rahmenbedingungen präsentiert. Dazu wurden die folgenden Fragestellungen formuliert: Wie könnte ein agiles Management in einem Orchesterbetrieb aussehen? Wo liegen Möglichkeiten und Grenzen für ein agiles Management in dem Kulturbetrieb Orchester? Zur Beantwortung dieser Fragen wurde eine Literaturarbeit durchgeführt. Die Ergebnisse dieser Arbeit zeigen, dass aufgrund der spezifischen Eigenschaften eines Orchesterbetriebs ein agiles Management nach heutigem Entwicklungsstand nicht eins zu eins übernommen werden kann. Einzelne agile Methoden und Praktiken können jedoch im Orchesterbetrieb durchaus Anwendung finden. Dies zeigt, dass eine agile Entwicklung eines Orchesterbetriebs noch am Anfang steht.

description: The statistical shapes of the highest pulse have been studied by aligned method. A wavelet package analysis technique and a developed pulse--finding algorithm have been applied to select the highest pulse from burst profiles observed by BATSE on board CGRO from 1991 April 21 to 1999 January 26. The results of this work show that the statistical shapes of the highest pulses are related to energy: the higher the energy, the narrower the pulse. However, the characteristic structures of the pulses have nothing to do with energy, which strongly supports the previous conclusion that the temporal profiles in different channels are self--similar. The characteristic structures of the pulses can be well described by a model proposed by Norris et al. (1996). The fitting parameters are: $t_r$=0.12, $t_d$=0.16, $\upsilon =1.09$, the ratio of $t_r$ to $t_d$ for the pulse is 0.75. The result leads to our conjecture that the mechanisms of bursts in different gamma-ray bands might be the same. The shock, either an internal or an external one, producing the pulse, might emit photons over the four energy channels in the same way.

description: The role of the agriculture sector in the economic development of Barbados has been substantially reduced as the country has continued on a path of economic diversification. Policy initiatives aimed towards this notable structural change in the economy, however, have subsequently resulted in a significant decline in output from the agriculture industry. However, recent global and national challenges have brought the need to rethink the relevance of the agriculture to the fore. This paper reviews some of the prevailing literature pertaining to the role of the agriculture on economic growth and development. In doing so, the potential scope of the industry for the overall economic growth and development of Barbados should be revealed. The paper also highlights two key agricultural issues that could potentially threaten economic development in Barbados. These are: the rising level of imports and rising food prices. Strategies that may be deemed beneficial to the local agricultural industry, if it is to remain a viable tool for national economic growth and development, will also be presented.

description: Magnetic topological insulators (TIs) with nontrivial topological electronic structure and broken time-reversal symmetry exhibit various exotic topological quantum phenomena. The realization of such exotic phenomena at high temperature is one of central topics in this area. We reveal that MnBi6Te10 is a magnetic TI with an antiferromagnetic ground state below 10.8 K whose nontrivial topology is manifested by Dirac-like surface states. The ferromagnetic axion insulator state with Z4 = 2 emerges once spins polarized at field as low as 0.1 T, accompanied with saturated anomalous Hall resistivity up to 10 K. Such a ferromagnetic state is preserved even external field down to zero at 2 K. Theoretical calculations indicate that the few-layer ferromagnetic MnBi6Te10 is also topologically nontrivial with a non-zero Chern number. Angle-resolved photoemission spectroscopy experiments further reveal three types of Dirac surface states arising from different terminations on the cleavage surfaces, one of which has insulating behavior with an energy gap of ~ 28 meV at the Dirac point. These outstanding features suggest that MnBi6Te10 is a promising system to realize various topological quantum effects at zero field and high temperature.
