description: The Van der Pol equation is a paradigmatic model of relaxation oscillations. This remarkable nonlinear phenomenon of self-sustained oscillatory motion underlies important rhythmic processes in nature and electrical engineering. Relaxation oscillations in a real system are usually coupled to environmental noise, which further enriches their dynamics, but makes theoretical analysis of such systems and determination of the equation's parameter values a difficult task. In a companion paper we have proposed an analytic approach to a similar problem for another classical nonlinear model, the bistable Duffing oscillator. Here we extend our techniques to the case of the Van der Pol equation driven by white noise. We analyze the statistics of solutions and propose a method to estimate parameter values from the oscillator's time series. We use experimental data of active oscillations in a biological system to demonstrate how our method applies to real observations and how it can be generalized for more complex models.

description: With respect to developing countries, it is observed that climate change poses a serious threat to economic growth and impediment to the poverty reduction programmes undertaken in these countries for the upliftment of the vulnerable households. It can also have a major impact on issue of food security which is highly dependent on climate sensitive parameters. Evidences from preliminary assessments also reveal that the severity of droughts and intensity of floods in various parts of India might increase due to climate change. The present paper attempts to study the vulnerability of rural households in a disaster prone region of India and study the mechanisms undertaken by these household to adapt to the risks faced to their consumption pattern. We use random effects panel data model to understand the risks to the consumption practices of households and the adaptation mechanism followed by them. The results suggest that income from livestock assets emerged as major adaptation strategy with respect to reducing the fluctuations in consumption by the household in the study area.

description: Climate variability, the short-term fluctuations in the weather and agriculture affect each other. Climate variability affects the agroecological and growing conditions of crops and livestock, and is recently believed to be the greatest impediment to the realisation of the first Millennium Development Goal of reducing poverty and food insecurity in arid and semi-arid regions of developing countries. Conversely, agriculture is a major contributor to climate variability and change by emitting greenhouse gases and reducing the agroecology’s potential for carbon sequestration. What however, is the empirical evidence of this inter-dependence of climate variability and agriculture in Sub-Sahara Africa? In this paper, I provide some insight into the long run relationship between inter-annual variations in temperature and rainfall, and annual yields of the most important staple food crops in Northern Ghana. Applying pooled panel data of rainfall, temperature and yields of the selected crops from 1976 to 2010 to cointegration and Granger causality models, there is cogent evidence of cointegration between seasonal, total rainfall and crop yields; and causality from rainfall to crop yields in the Sudano-Guinea Savannah and Guinea Savannah zones of Northern Ghana. This suggests that inter-annual yields of the crops have been influenced by the total mounts of rainfall in the planting season. Temperature variability over the study period is however stationary, and is suspected to have minimal if any effect on crop yields. Overall, the results confirm the appropriateness of my attempt in modelling long-term relationships between the climate and crop yield variables.

description: Researchers and lay people alike have long held an interest in understanding the antecedents, mechanisms, and consequences of prosocial behaviours: Acts people behave in ways that benefit others, such as cooperation, altruism, care-giving, empathy, sympathy, and compassion. Numerous lines of inquiry have now documented that acting prosocially carries many benefits for not only the recipient, but also the actor. For instance, acting prosocially attracts social capital, social support, and boosts interpersonal relationships; prosociality also increases one’s well-being, happiness, and has long-term physical and mental health benefits. While much of the past work has focused on the main effects of prosociality on various positive outcomes, one area that has received limited attention is understanding the contextual factors and individual differences that moderate these relationships. In the present thesis, I focus on understanding how socioeconomic status (SES) acts as a moderator of the link between prosociality and numerous positive outcomes. In particular, I examined how prosociality is related to building social networks through weak ties, coping with daily stress, and building interpersonal skills. Across these relationships, I examined how SES moderates the link between prosociality and each outcome. My research was guided by the SES-prosociality paradox: That while the rich have access to far greater resources – and thus the ability to act prosocially – it is the poor that tend to act most generously. I theorized that one reason for this paradox is that people across different SES strata benefit differently from acting prosocially. In particular, I reasoned that the people from lower SES backgrounds will tend to have stronger relationship between prosociality and various positive outcomes than people from higher SES backgrounds. To test this hypothesis, I conducted numerous empirical studies using multiple methods – analysing data from subjective reports via surveys and existing data from social media, running natural experiments, and conducting lab experiments using genetic and pharmacological challenge methods. In Chapters 2 and 3, I found that people who act prosocially tend to attract more weak social ties – this is only true for the relatively poor. In Chapter 4, I tested how empathic traits relate to better coping strategies for both lower and higher SES individuals, and found a complex pattern of differing benefits. Finally, in Chapter 5, I found that intranasal oxytocin improves emotional theory of mind, but only for the low SES individuals.

description: The unavoidable residual tumor tissue from surgery and the strong aggressiveness of tumor cells pose challenges to the postoperative treatment of tumor patients, accompanied by in situ tumor recurrence and decreased quality of life. Therefore, there is an urgent need to explore appropriate postoperative therapeutic strategies to remove residual tumor cells after surgery to inhibit tumor recurrence and metastasis after surgery. In recent years, with the rapid development of biomedical materials, the study of local delivery systems as postoperative delivery of therapeutic agents has gradually attracted the attention of researchers. Injectable in situ-forming hydrogel is a locally administered agent injected in situ as a solution that can be loaded with various therapeutic agents and rapidly gels to form a semi-solid gel at the treatment site. This type of hydrogel tightly fills the surgical site and covers irregular excision surfaces. In this paper, we review the recent advances in the application of injectable in situ-forming hydrogels in postoperative therapy, focusing on the matrix materials of this type of hydrogel and its application in the postoperative treatment of different types of tumors, as well as discussing the challenges and prospects of its clinical application.

description: Failure to consider the needs of families on small farms during the formulation of agricultural development policies may result in unexpected inequities that worsen the small farmers' disadvantaged circumstances. An important challenge facing policymakers is the identification and implementation of strategies which will increase agricultural production and trade (growth consideration) without disenfranchising or eliminating small scale farmers (equity consideration), especially when agricultural producers are at both extremes of the size spectrum. The question of who benefits from agricultural development has proved increasingly important in recent years. The integration and participation of small farmers in agricultural development efforts is one of the most challenging problems for agricultural economists today. This report is a result of cooperation and interaction between Brazilian and U.S. agricultural economists and Portuguese agriculturists. It is based on observation, published reports, and primary data collected in small farm surveys in each of the three countries. We first describe the three widely separated study areas and indicate that the presence of substantial numbers of small, economically disadvantaged farms in each area suggests that they have not been fully integrated into the economy. Second, we describe three common agricultural policies and programmes and the barriers they contain to small farm participation. Data and observations from a highly developed, a recently developed, and an emerging agricultural sector are used to illustrate the lack of small farm integration into public policies for agriculture.

description: Cubic chiral magnets, such as Cu$_{2}$OSeO$_{3}$, exhibit a variety of non-collinear spin textures, including a trigonal lattice of spin whirls, so-called skyrmions. Using magnetic resonant elastic x-ray scattering (REXS) on a crystalline Bragg peak and its magnetic satellites while exciting the sample with magnetic fields at GHz frequencies, we probe the ferromagnetic resonance modes of these spin textures by means of the scattered intensity. Most notably, the three eigenmodes of the skyrmion lattice are detected with large sensitivity. As this novel technique, which we label REXS-FMR, is carried out at distinct positions in reciprocal space, it allows to distinguish contributions originating from different magnetic states, providing information on the precise character, weight and mode mixing as a prerequisite of tailored excitations for applications.

description: We report the XRD and Raman scattering measurements in combination with DFT calculations that reveal the formation of beryllium polyhydride Be4H8(H2)2 by laser heating Be/H2 mixture to above 1700 K at pressures between 5 GPa and 8 GPa. The Be4H8(H2)2 crystallizes in a P6_3/mmc structure and consists of corner-sharing BeH4 tetrahedrons and H2 molecules that are in an interstitial site. The Be4H8(H2)2 is stable at least to 14 GPa on compression and stable down to 4 GPa at room temperature. Our ab-initio calculations suggest that the Be4H8(H2)2 is a meta-stable phase of Be-H system.

description: We study strong instability (by blow-up) of the standing waves for the nonlinear Schrödinger equation with $δ$-interaction on a star graph $Γ$. The key ingredient is a novel variational technique applied to the standing wave solutions being minimizers of a specific variational problem. We also show well-posedness of the corresponding Cauchy problem in the domain of the self-adjoint operator which defines $δ$-interaction. This permits to prove virial identity for the $H^1$- solutions to the Cauchy problem. We also prove certain strong instability results for the standing waves of the NLS-$δ'$ equation on the line.

description: We present the topology of a volume-limited sample of 11,884 galaxies, selected from an apparent-magnitude limited sample of over 100,000 galaxies observed as part of the Sloan Digital Sky Survey (SDSS). The data currently cover three main regions on the sky: one in the Galactic north and one in the south, both at zero degrees declination, and one area in the north at higher declination. Each of these areas covers a wide range of survey longitude but a narrow range of survey latitude, allowing the two dimensional genus to be measured. The genus curves of the SDSS sub-samples are similar, after appropriately normalizing these measurements for the different areas. We sum the genus curves from the three areas to obtain the total genus curve of the SDSS. The total curve has a shape similar to the genus curve derived from mock catalogs drawn from the Hubble Volume Lambda CDM simulation and is similar to that of a Gaussian random field. Likewise, comparison with the genus of the 2dFGRS, after normalization for the difference in area, reveals remarkable similarity in the topology of these samples. We test for the effects of galaxy type segregation by splitting the SDSS data into thirds, based on the u^*- r^* colors of the galaxies, and measure the genus of the reddest and bluest sub-samples. This red/blue split in u^*- r^* is essentially a split by morphology (Strateva et al. 2001). We find that the genus curve for the reddest galaxies exhibits a ``meatball'' shift of the topology -- reflecting the concentration of red galaxies in high density regions -- compared to the bluest galaxies and the full sample, in agreement with predictions from simulations.

description: The searching for the electric dipole moments (EDMs) of neutron ($d_n$), $b$ quark ($d_b$) and $c$ quark ($d_c$) gives strict upper bounds on these quantities. And recently, new upper bounds on $d_b$, $d_c$ are obtained by the strict limit on $d_n$. The models of new physics (NP) with additional CP-violating (CPV) sources are constrained strictly by these EDMs. In this work, we focus on the CPV effects on these EDMs in the minimal supersymmetric extension (MSSM) of the SM with local $B-L$ gauge symmetry (B-LSSM). The contributions from one-loop and some two-loop diagrams to the quark EDM are given in general form, which can also be used in the calculation of quark EDM in other models of NP. Considering the constrains from updated experimental data, the numerical results show that the two-loop corrections can make important contributions to these EDMs. Compared with the MSSM, the effects of new CPV phases and new parameters in the B-LSSM on these EDMs are also explored.

description: The identification of flavored multiskyrmions with the ground states of known hypernuclei is successful for several of them, e.g. for isodoublet H(Lambda) - He(Lambda), A=4, isoscalars He(Lambda) (A=5) and Li(Lambda) (A=7). In other cases agreement is not so good, but the behaviour of the binding energy with increasing baryon number is in qualitative agreement with data. Charmed or beauty hypernuclei within this approach are predicted to be bound stronger than strange hypernuclei. This conclusion is stable against variation of poorly known heavy flavor decay constants.

description: We calculate the 3-loop bare $β$-function of QCD, formulated on the lattice with the clover fermionic action. The dependence of our result on the number of colors $N$, the number of fermionic flavors $N_f$, and the clover parameter $c_{SW}$, is shown explicitly. A direct outcome of our calculation is the two-loop relation between the bare coupling constant $g_0$ and the one renormalized in the MS-bar scheme. Further, we can immediately derive the three-loop correction to the relation between the lattice $Λ$-parameter and $g_0$, which turns out to be very pronounced. We also calculate the critical value of the hopping parameter, $κ_c$, in the clover action, to two loops in perturbation theory. This quantity is an additive renormalization; as such, it exhibits a linear divergence in the lattice spacing. We compare our results to non perturbative evaluations of $κ_c$ coming from MC simulations.

description: We discuss selected and important features of hadronic molecules as one of promising forms of exotic hadrons near thresholds. Using examples of $D \bar D^*$ systems such as $X(3872)$ and $Z_c$, emphasis is put on the roles of the one pion exchange interaction between them and their coupling to intrinsic quark states. Thus hadronic molecules emerge as admixtures of the dominant long-range hadron structure and short-range quark structure. For the pion exchange interaction, properties of the tensor force are analyzed in detail. More coupled channels supply more attractions, and heavier constituents suppress kinetic energies, providing more chances to form hadronic molecules of heavy hadrons. Throughout this article, we show details of basic ideas and methods.

description: This thesis investigates the significance of the notion of fantasia for artists and critics of art in Italy during the sixteenth century up to the definitive edition of Giorgio Vasari’s Lives (1568). It charts the pre-history of this term in an age before the imagination was attributed paramount importance in aesthetics, yet in a time when artists already intensively debated the mental powers at play in their practice. In this context, fantasia was a controversial faculty and an ambivalent term of ekphrasis. Its appeal as a philosophical concept was counteracted by its vexed role in the psychology of perception, where it was sometimes appraised as an uncontrollable pictorial agent that accidentally agglomerated mental images. In the wake of early Mannerist anti-classicism and its valuation of abnormality, fantasia was reclaimed as an irrational creative process allowing for formal renewal. The imagination, however, was not yet understood as ‘creative’ in the modern sense. Its potential for innovation was limited to the recombination of elements previously observed in nature. As the supremacy of mimesis (imitation) was increasingly put into question, the combinatorial model of invention fantasia stood for became a major paradigm through which the question of non-naturalistic form was problematized. The beliefs attached to fantasia, therefore, structured the early modern thinking about the nature of pictorial fiction, the value of artistic innovation and its relation to selfhood and subjectivity in the years leading up to the Council of Trent and the academisation of art. We argue that fantasia is essential to understanding some of the earliest aesthetic reflections on the unconscious dimension of creation and the share of unpredictability and accident inherent in any attempt at artistic renewal.

description: The capability to rapidly and successfully move into new business models is an important source of sustainable competitive advantage and a key leverage to improve the sustainability performance of organisations. However, research suggests that many business model innovations fail. Despite the importance of the topic, the reasons for failure are relatively unexplored, and there is no comprehensive description of the sustainable business model innovation process in the literature. This research addresses this gap by sequentially employing four research methods. First, a literature review is conducted to synthesise a conceptual model as a framework for an empirical investigation. This investigation used two focus groups with ten participants, interviews with 61 senior managers of 24 organisations, and active participatory research, in which the researcher joined the teams of two different business model innovation projects for several months. The research provides the most comprehensive literature review on the definition and process of sustainable business model innovation to date. It identifies five different process steps of sustainable business model innovation as well as a comprehensive list of key activities and challenges associated with each step of the process. It also discusses how the resulting process framework could be translated into a management tool and outlines some insights on the organisational setup of the process and success factors. These findings can serve as hypotheses to guide further research on sustainable business model innovation and adjacent phenomena. It also provides direction for practitioners engaged in sustainable business model innovation in similar context as the ones investigated. As a result, the research can help organisations to structure their activities better, anticipate key challenges, and build up sustainable business model innovation capabilities.

description: We study the collective excitations, i.e., the Goldstone (phase) mode and the Higgs (amplitude) mode, near the superfluid--Mott glass quantum phase transition in a two-dimensional system of disordered bosons. Using Monte Carlo simulations as well as an inhomogeneous quantum mean-field theory with Gaussian fluctuations, we show that the Higgs mode is strongly localized for all energies, leading to a noncritical scalar response. In contrast, the lowest-energy Goldstone mode undergoes a striking delocalization transition as the system enters the superfluid phase. We discuss the generality of these findings and experimental consequences, and we point out potential relations to many-body localization.

description: In certain analytically-tractable quantum chaotic systems, the calculation of out-of-time-order correlation functions, entanglement entropies after a quench, and other related dynamical observables, reduces to an effective theory of an ``entanglement membrane'' in spacetime. These tractable systems involve an average over random local unitaries defining the dynamical evolution. We show here how to make sense of this membrane in more realistic models, which do not involve an average over random unitaries. Our approach relies on introducing effective pairing degrees of freedom in spacetime, describing a pairing of forward and backward Feynman trajectories, inspired by the structure emerging in random unitary circuits. This provides a framework for applying ideas of coarse-graining to dynamical quantities in chaotic systems. We apply the approach to some translationally invariant Floquet spin chains studied in the literature. We show that a consistent line tension may be defined for the entanglement membrane, and that there are qualitative differences in this tension between generic models and ``dual-unitary'' circuits. These results allow scaling pictures for out-of-time-order correlators and for entanglement to be taken over from random circuits to non-random Floquet models. We also provide an efficient numerical algorithm for determining the entanglement line tension in 1+1D.

Between order and disorder: ultracold atoms in a quasicrystalline optical lattice

Aperiodic order

description: Quasicrystals are long-range ordered and yet non-periodic. This interplay results in a wealth of intriguing physical phenomena, such as self-similarity, the inheritance of topological properties from higher dimensions, and the presence of non-trivial structure on all lengthscales. However, quasicrystalline materials are notoriously hard to synthesise, as defects and impurities may greatly alter their final microscopic composition. The field of quantum simulation with ultracold atoms offers a solution to this problem, namely the use of optical lattices – standing waves of light. Optical lattices are free of impurities and therefore ideally suited to study quasicrystals, enabling unprecedented access to observables that are unattainable in condensed matter systems. This study presents the first experimental realisation of a two-dimensional quasicrystalline potential for ultracold atoms, based on an eightfold symmetric optical lattice. Features pertaining to both ordered and disordered phases are observed, from sharp diffraction peaks in the matter-wave interference pattern, to a disorder-induced localised phase emerging at a critical lattice depth V_loc ~ 1.78 E_rec. The localised phase seems to be resilient against moderate interactions, which would make this the first experimental realisation of a 2D Bose glass.

description: Fluid driven fractures propagate in the upper earth crust either naturally or in response to engineered fluid injections. The quantitative prediction of their evolution is critical in order to better understand their dynamics as well as to optimize their creation. We present a Python implementation of an open-source hydraulic fracture propagation simulator based on the implicit level set algorithm originally developed by Peirce & Detournay (2008) -- "An implicit level set method for modeling hydraulically driven fractures". Comp. Meth. Appl. Mech. Engng, (33-40):2858--2885. This algorithm couples a finite discretization of the fracture with the use of the near tip asymptotic solutions of a steadily propagating semi-infinite hydraulic fracture. This allows to resolve the multi-scale processes governing hydraulic fracture growth accurately, even with relatively coarse meshes. We present an overview of the mathematical formulation, the numerical scheme and the details of our implementation. A series of problems including a radial hydraulic fracture verification benchmark, the propagation of a height contained hydraulic fracture, the lateral spreading of a magmatic dyke and the handling of fracture closure are presented to demonstrate the capabilities, accuracy and robustness of the implemented algorithm.

description: Energy is intricately related to agricultural production. Plants capture solar energy and convert it into food, energy, and other products useful for mankind. Agriculture is potentially a source of not only food, feed, and fibre, but also of energy. Agriculture is also an important user of energy. Technical progress in agriculture has meant more intensive use of commercial energy in agriculture. The rapid escalation of energy prices in the 1970s has important efficiency and equity implications for agriculture. This paper reviews the relationships between energy and agriculture with agriculture as both a producer and a consumer of energy.

description: We combine near-infrared photometry obtained with the VLT/ISAAC instrument and archival HST/WFPC2 optical images to determine VIK magnitudes and colours of globular clusters in two early-type galaxies, NGC 3115 and NGC 4365. The combination of near-IR and optical photometry provides a way to lift the age-metallicity degeneracy. For NGC 3115, the globular cluster colours reveal two major sub-populations, consistent with previous studies. By comparing the V-I, V-K colours of the NGC 3115 globular clusters with SSP models, we find that the colour difference between the two >10 Gyr old major sub-populations is primarily due to a difference in metallicity. We find Δ[Fe/H] = 1.0 +/- 0.3 dex and the blue and red globular cluster sub-populations being coeval within 3 Gyr. In contrast to the NGC 3115 globular clusters, the globular cluster system in NGC 4365 exhibits a more complex age and metallicity structure. We find a significant population of intermediate-age very metal-rich globular clusters along with an old population of both metal-rich and metal-poor clusters. Specifically, we observe a large population of globular clusters with V-K and V-I colours, for which all current SSP models give ages and metallicities in the range ~2-8 Gyr and ~0.5-3 Z_solar, respectively. After 10 Gyr of passive evolution, the intermediate-age globular clusters in NGC 4365 will have colours which are consistent with the very metal-rich population of globular clusters in giant elliptical galaxies, such as M87. Our results for both globular cluster systems are consistent with previous age and metallicity studies of the diffuse galactic light. In addition to the major globular cluster populations in NGC 3115 and NGC 4365 we report on the detection of objects with extremely red colours.

description: A significant proportion of patients with affective and psychotic disorders show a marked reduction in goal-directed behaviour, which is also reflected in the behavioural outcomes of effort-based decision-making paradigms. The factors underlying this reduction are not yet fully understood. Reward salience and reward expectancy have been discussed as factors that potentially influence approach behaviour. The aim of this study was thus to test their effects on behaviour in an effort-based decision-making paradigm. In two studies with community samples we applied a modified version of the Balloon Task. In study 1, we manipulated reward salience in a within-subject design (N = 32) by highlighting the monetary rewards. In study 2, we manipulated reward expectancy in a between-subject design (N = 72) by adding five practice trials with either positive or negative feedback prior to the task. The salience of rewards manipulation significantly increased effort expenditure and the allocation of effort to the level of rewards whereas the reward expectancy manipulation did not. The finding that increasing the salience of rewards increases motivated behaviour in an effort-based decision-making paradigm offers promising possibilities for intervention in disorders characterised by motivational deficits, such asaffective and psychotic disorders.
