description: Destabilization of a ligand-stabilized semiconductor nanocrystal solution with an oxidizing agent can lead to a macroscopic highly porous self-supporting nanocrystal network entitled hydrogel, with good accessibility to the surface. The previously reported charge carrier delocalization beyond a single nanocrystal building block in such gels can extend the charge carrier mobility and make a photocatalytic reaction more probable. The synthesis of ligand-stabilized nanocrystals with specific physicochemical properties is possible, thanks to the advances in colloid chemistry made in the last decades. Combining the properties of these nanocrystals with the advantages of nanocrystal-based hydrogels will lead to novel materials with optimized photocatalytic properties. This work demonstrates that CdSe quantum dots, CdS nanorods, and CdSe/CdS dot-in-rod-shaped nanorods as nanocrystal-based hydrogels can exhibit a much higher hydrogen production rate compared to their ligand-stabilized nanocrystal solutions. The gel synthesis through controlled destabilization by ligand oxidation preserves the high surface-to-volume ratio, ensures the accessible surface area even in hole-trapping solutions and facilitates photocatalytic hydrogen production without a co-catalyst. Especially with such self-supporting networks of nanocrystals, the problem of colloidal (in)stability in photocatalysis is circumvented. X-ray photoelectron spectroscopy and photoelectrochemical measurements reveal the advantageous properties of the 3D networks for application in photocatalytic hydrogen production.
Migration, education and culture: a macroeconomic perspective

Subjects: Uncategorized

description: This thesis consists of four self-contained empirical studies, with three underlying themes: Migration, Education and Culture. First, using annual data over the period 1820-2010, Chapter 2 examines the productivity effects of immigrants’ traits on growth in Argentina, Australia, Brazil, Canada, New Zealand and the United States. Immigrants’ traits such as wealth, culture, institutions, R&D knowledge, and education are traced back to their country of origin. Culture is found to be consistently the most important productivity-enhancing trait of immigrants, followed by education. Second, using annual data over the period 1850-2010, Chapter 3 examines the impact of immigration as well as the immigrants’ educational and cultural background on unemployment in Argentina, Australia, Brazil, Canada, New Zealand and the United States. The results show that immigrants lowered unemployment before WWII but not thereafter and that immigrants from Protestant countries have lowered unemployment throughout the entire period, 1850-2010. Third, using panel data on the eight Australian states and territories, Chapter 4 examines the effects of migration on house prices in Australia from 1971-2013, accounting for both international and internal migratory movements. The results show that migration driven population growth has a significant effect on house prices in the short-run and that inter-state migration needs to be account for due to the large inter-state movements. Overall, the other results are relatively consistent with existing literature. In the short-run, housing prices are significantly driven by inertia in house prices, interest rates, the unemployment rate and income. In the long run however, house prices are driven by their replacement costs, measured by construction costs. Last, using panel data of 21 OECD countries from 1820 to 2009, Chapter 5 seeks to explain the mass rise in education we have witnessed in the last few centuries. Specifically, it examines the impact of government regulation in the form of compulsory schooling laws and child labour laws, culture, life returns to education, structural changes in the economy and the sequential nature of schooling on school enrolment rates – primary, secondary and tertiary. Results suggest that primary and secondary schooling is significantly influenced by government regulation on schooling and that more liberal cultural values, higher life expectancy and an expansion of the knowledge intensive sector have a positive effect on enrolment across the three levels of schooling.

Fe impurities as pinning centers and crystalline anisotropy are found non-negligible only at the boundary of the A-phase. Electrical transport characteristics unique to the A-phase not only remain robust, but also indicate a freely rotating skyrmion lattice, decoupled from underlying crystal structure or impurity pinning.

description: The present paper takes up the underlying nonlinear initial value problem from a preceding author’s work about the dynamics of a single bubble in a highly viscous liquid medium under different pressure impacts. The arising ordinary differential equation is mainly based on the constitutive relation of a second-order liquid that in particular includes two non-Newtonian material constants. In this article, the significance of these coefficients is mathematically analyzed in detail by proving the existence of stable solutions of the named initial value problem. This is achieved by special transformations of the differential equation at hand and the introduction of appropriate Lyapunov functions. It particularly turns out that a combined condition of the non-Newtonian coefficients and diverse restrictions to the external pressure impact are decisive for the validity of the existence results. Furthermore, the convergence speed of solutions is investigated by considering the linearized equation associated with the present initial value problem and by applying a special variant of Gronwall’s lemma. The main theoretical result, being the prementioned strong condition for the non-Newtonian coefficients, is finally compared to real data sets.

On computing the distance to stability for matrices using linear dissipative Hamiltonian systems
Creators: name: Gillis, Nicolas

Publisher: name: arXiv
Year: 2016
Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: In this paper, we consider the problem of computing the nearest stable matrix to an unstable one. We propose new algorithms to solve this problem based on a reformulation using linear dissipative Hamiltonian systems: we show that a matrix $A$ is stable if and only if it can be written as $A = (J-R)Q$, where $J=-J^T$, $R \succeq 0$ and $Q \succ 0$ (that is, $R$ is positive semidefinite and $Q$ is positive definite). This reformulation results in an equivalent optimization problem with a simple convex feasible set. We propose three strategies to solve the problem in variables $(J,R,Q)$: (i) a block coordinate descent method, (ii) a projected gradient descent method, and (iii) a fast gradient method inspired from smooth convex optimization. These methods require $\mathcal{O}(n^3)$ operations per iteration, where $n$ is the size of $A$. We show the effectiveness of the fast gradient method compared to the other approaches and to several state-of-the-art algorithms.

description: The spin-asymmetric Josephson effect is a proposed quantum-coherent tunnelling phenomenon where Cooper-paired fermionic spin-$\frac{1}{2}$ particles, which are subjected to spin-dependent potentials across a Josephson junction, undergo frequency-synchronized alternating-current Josephson oscillations with spin-dependent amplitudes. Here, in line with present-day techniques in ultracold Fermi gas setups, we consider the regime of small Josephson oscillations and show that the Josephson plasma oscillation amplitude becomes spin-dependent in the presence of spin-dependent potentials while the Josephson plasma frequency is the same for both spin-components. Detecting these spin-dependent Josephson plasma oscillations provides a possible means to establish the yet-unobserved spin-asymmetric Josephson effect with ultracold Fermi gases using existing experimental tools.

description: A strategy of continuous team assessment over three years, comprising of a series of tests and a major project, was introduced into scheduled tutorial classes in an attempt to improve flagging attendance and low student motivation. The assessment tasks were designed to be undertaken in teams of two students, with ongoing feedback as an integral component. After a single semester of implementation, attendance at tutorials improved (to nearly double the previous year), and this rate was sustained over a three year period. Average assessment marks rose a full grade compared to the previous student cohort, and this was also sustained over the same period. Students' output improved, and they were actively engaged in their work and with their colleagues. These results indicate the change in assessment strategy achieved the desired outcomes of improving student engagement and active learning.

description: Classical imaging works by scattering photons from an object to be imaged, and achieves resolution scaling as $1/\sqrt{t}$, with $t$ the imaging time. By contrast, the laws of quantum mechanics allow one to utilize quantum coherence to obtain imaging resolution that can scale as quickly as $1/t$ -- the so-called "Heisenberg limit." However, ambiguities in the obtained signal often preclude taking full advantage of this quantum enhancement, while imaging techniques designed to be unambiguous often lose this optimal Heisenberg scaling. Here, we demonstrate an imaging technique which combines unambiguous detection of the target with Heisenberg scaling of the resolution. We also demonstrate a binary search algorithm which can efficiently locate a coherent target using the technique, resolving a target trapped ion to within 0.3% of the $1/e^2$ diameter of the excitation beam.

description: In this paper, we propose a conservative local discontinuous Galerkin method for one-dimensional nonlinear Schrödinger equation. By using special upwind-biased numerical fluxes, we establish the optimal rate of convergence $\mathcal O(h^{k+1})$, with polynomial of degree $k$ and grid size $h$. Meanwhile, we show that this method preserves the charge conservation law and thus we call it a conservative local discontinuous Galerkin method. Numerical experiments verify our theoretical result.
Experimental evidence that electrical fatigue failure obeys a generalized Coffin-Manson law

description: The empirical Coffin-Manson law has been used to characterize the low-cycle mechanical fatigue failure of metallic materials for decades. Our experimental studies reported in this letter have shown that the electrical fatigue failure in dielectrics can be well described by a fitting function having the same mathematical expression as that of the Coffin-Manson law. This observation indicates that the physical mechanism beneath the formation and evolution of atomic disordered structures, the key factor influencing both mechanical and electrical fatigue, might be the same.

Phase diagram of UCoGe

description: The temperature-pressure phase diagram of ferromagnetic superconductor UCoGe includes four phase transitions. They are between the paramagnetic and the ferromagnetic states with the subsequent transition in the superconducting ferromagnetic state and between the normal and the superconducting states after which has to occur the transition to the superconducting ferromagnetic state. Here we have developed the Landau theory description of the phase diagram and established the specific ordering arising at each type of transition. The phase transitions to the ferromagnetic superconducting state are inevitably accompanied by the emergency of screening currents. The corresponding magnetostatics considerations allow to establish the significant difference between the transition from the ferromagnetic to the ferromagnetic superconducting state and the transition from the superconducting to the ferromagnetic superconducting state.

description: Das schweizerische Engagement in der Neutral Nations Supervisory Commission (NNSC) in Korea ist das Aushängeschild der helvetischen «Guten Dienste». Seit 1953 wacht die Schweiz am 38. Breitengrad in Panmunjom gemeinsam mit Schweden als neutrale Vertreterin der Südseite über die Einhaltung des Waffenstillstands in Korea, während die Tschechoslowakei (bis 1993) und Polen (bis 1995) die Nordseite vertraten. Da bereits 1956 jegliche Kontrolltätigkeit suspendiert wurde, gilt seither die reine Präsenz der Kommission als Garant für den Waffenstillstand. Durch ihren Einsitz in der NNSC befand sich die international sonst so zurückhaltende Schweiz an vorderster Front eines der Fieberkurve des Kalten Kriegs folgenden Konflikts.
In diesem Band werden siebzig Dokumente zur Geschichte der NNSC und der schweizerischen Beteiligung präsentiert, welche insbesondere die politische und diplomatische Dimension beleuchten. Dank der Verknüpfung mit zahlreichen weiteren Dokumenten und Informationen in der Datenbank Dodis wird die Quellensammlung zu einem wertvollen Kompass für weitere Forschungen.
description: Switzerland’s involvement in the Neutral Nations Supervisory Commission (NNSC) in Korea is the flagship of its «Good Offices». Since 1953, Switzerland has been watching over the observance of the armistice in Korea at the 38th parallel in Panmunjom together with Sweden as the neutral representative of the southern side, while Czechoslovakia and Poland represented the northern side (respectively until 1993 and 1995). Since any monitoring activity was suspended as early as 1956, the mere presence of the Commission has since been regarded as a guarantor of the armistice. Through its seat on the NNSC, Switzerland, otherwise so reserved in foreign policy, found itself internationally at the forefront of a conflict that always followed the fever curve of the Cold War.
This volume presents seventy documents on the history of the NNSC and the Swiss participation, shedding light in particular on the political and diplomatic dimension. Thanks to the linkage with numerous other documents and information in the Dodis database, the collection of sources becomes a valuable compass for further research.

description: We provide a field-theoretic algorithm of obtaining energy momentum tensor (EMT) for gravitationally coupled theories. The method is based on an auxiliary field theory and equally applicable to both minimal and non-minimal coupling. The algorithm illuminates the connection between the EMT, obtained by functional variation of the metric, and local balance of energy and momentum. Our method is of cardinal value for the proper identification of the EMT in context of non-minimally coupled gravity theories.

Essays in political economy
Creators: name: Skali, Ahmed
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: The first essay uncovers a causal link running from democratic institutions to development. Time-varying instruments for democracy are used, allowing a causal interpretation of the results that is not contaminated by feedback effects running from income to democracy. The main instrument used for domestic democracy is the lagged average level of democracy in cultural neighbors, which is motivated by theories of democratic diffusion in political science. To bypass the issue of spatial correlation attendant to the use of geographic distance-weighted democracy, the instrument is weighted by linguistic distance. The rationale is that the speed at which political ideas and movements spread between two countries is inversely related to the linguistic distance between those two countries. In addition, human capital is also instrumented using data on minimum working age and minimum years of schooling. The second essay contributes to the literature on political leaders and economic outcomes by showing that leaders affect technical change. Innovation is a cornerstone of economic growth; the study is the first to investigate the effects of political leaders on innovation. I use the deaths of political leaders while in power as quasi-experiments where the timing of political transitions is unrelated to any socioeconomic trends, unlike other political transitions (through, say, elections or coups). I find strong empirical evidence that political leaders affect innovation. Using bootstrap sampling, I also show that foreign-educated leaders have positive effects on technical change. The third essay studies the links between pre-modern belief systems and contemporary armed conflicts, which provides an empirical test of the theoretical proposition that where credible commitments to peace are more difficult, more violence erupts. I use ethnographic data on the belief systems of African societies prior to European colonization along with geo-referenced data on armed conflicts from 1997 to 2013. The results show that both the incidence and intensity of conflict are negatively correlated with belief rigidity. More rigid belief systems are systematically associated with worsened violence. The proposed economic mechanism is that of an increase in inter-group coordination costs. Holding all else constant, economic theory suggests that societies whose belief systems are the most intransigent find compromise more costly, which raises the incidence and intensity of armed conflict. This result is robust to controlling for rich sets of economic, geographic, and cultural variables that can affect conflict through their effects on belief systems.

description: Motivated by our limited knowledge of the Higgs couplings to first two generation fermions, we analyze the collider phenomenology of a class of two Higgs doublet models (2HDMs) with a non-standard Yukawa sector. One Higgs doublet is mainly responsible for the masses of the weak gauge bosons and the third generation fermions, while the second Higgs doublet provides mass for the lighter fermion generations. The characteristic collider signatures of this setup differ significantly from well-studied 2HDMs with natural flavor conservation, flavor alignment, or minimal flavor violation. New production mechanisms for the heavy scalar, pseudoscalar, and charged Higgs involving second generation quarks can become dominant. The most interesting decay modes include H/A -> cc, tc, μμ, τμ and H+ -> cb, cs, μν. Searches for low mass di-muon resonances are currently among the best probes of the heavy Higgs bosons in this setup.

description: We investigate the behavior of entanglement entropy in the holographic QCD model proposed by Gubser et al. By choosing suitable parameters of the scalar self-interaction potential, this model can exhibit various types of phase structures: crossover, first order and second order phase transitions. We use entanglement entropy to probe the crossover/phase transition, and find that it drops quickly/suddenly when the temperature approaches the critical point which can be seen as a signal of confinement. Moreover, the critical behavior of the entanglement entropy suggests that we may use it to characterize the corresponding phase structures.

description: Starting from a graded Frobenius superalgebra $B$, we consider a graphical calculus of $B$-decorated string diagrams. From this calculus we produce algebras consisting of closed planar diagrams and of closed annular diagrams. The action of annular diagrams on planar diagrams can be used to make clockwise (or counterclockwise) annular diagrams into an inner product space. Our main theorem identifies this space with the space of symmetric functions equipped with the Jack inner product at Jack parameter $\operatorname{dim} B_\mathrm{even} - \operatorname{dim} B_\mathrm{odd}$. In this way, we obtain a graphical realization of that inner product space.

description: Motivated by correlated decay processes producing gain, loss and lasing in driven semiconductor quantum-dots, we develop a theoretical technique using Keldysh diagrammatic perturbation theory to derive a Lindblad master equation that goes beyond the usual second order perturbation theory. We demonstrate the method on the driven dissipative Rabi model, including terms up to fourth order in the interaction between the qubit and both the resonator and environment. This results in a large class of Lindblad dissipators and associated rates which go beyond the terms that have previously been proposed to describe similar systems. All of the additional terms contribute to the system behaviour at the same order of perturbation theory. We then apply these results to analyse the phonon-assisted steady-state gain of a microwave field driving a double quantum-dot in a resonator. We show that resonator gain and loss are substantially affected by dephasing-assisted dissipative processes in the quantum-dot system. These additional processes, which go beyond recently proposed polaronic theories, are in good quantitative agreement with experimental observations.

title: The influence of menstruation on training schedules in well-trained and elite female mountain bike, road and cyclocross athletes
Creators: name: Aitkenhead, Robyn

description: Female physiology is unique and driven by fluctuations in sex hormones that regulate the menstrual cycle (MC) (Marsh et al., 2002). These hormones present a myriad of mechanisms that may influence physiological systems, potentially implicating exercise performance. However, research exploring the MC in athletes is limited. This study investigated if different phases of the MC influenced training schedules, sleep quality, arousal and alertness in elite female mountain bike, road and cyclocross athletes. The study was approved by Edinburgh Napier University’s ethics committee. Fifteen well-trained (N=7) and elite (N=8) cyclists (age: 29 ± 7.4 years, height: 1.7 ± 0.1m, body mass: 61.9 ± 7.7kg) tracked their MC symptoms, basal body temperature (BBT), body mass, perceived sleep, and psychological measures daily for 3 months. The MC was split into two phases, follicular (FP) and luteal (LP), and participants were provided ovulation kits to identify the phases. Athlete’s BBT was significantly higher (p<0.05) in the LP (0.21ºC, p=0.00, d=0.4). No significant differences in body mass (FP; 61.8 ± 6.0, LP; 61.0 ± 6.6), sleep duration (FP; 8.0 ± 1 hrs, LP; 8.0 ± 1 hrs), perceived sleep quality (FP; 7 (7-7.8), LP; 7 (7-8)), alertness (FP; 6 (5-7), LP; 7 (6-7)) and arousal (FP; 3 (2-5), LP; 3 (2-5)) were observed. Further, no significant differences for any training variables, average heart rate (FP; 128 ± 37 bpm, LP; 128 ± 38 bpm), training load (bTRIMP) (FP; 173.5 ± 148.6 A.U, LP; 189.8 ± 158.3 A.U), average speed (FP; 19.3 ± 15.6 km.hr, LP; 18.8 ± 9.0 km.hr) and rating of perceived exertion (RPE) (FP; 13.2 ± 2.7, LP; 13.4 ± 3.0) were observed. Several limitations of this study included the lack of hormonal verification underpowered, and a larger cohort with an even discipline split is required to determine more significant values. In conclusion, the MC does not influence physiological responses and training variables in well-trained and elite mountain bike, road and cyclocross female athletes.

description: Determinants of CEO pay and its alignment with firm performance have been a topic of considerable debate for over a decade. Thus far, the evidence examining the effectiveness of governance mechanisms on CEO pay is mixed at best. As such, the aim of this study is to provide an alternative explanation by investigating the joint effects of director interlocks, measured as firm centrality, and corporate governance quality on CEO pay. This is supported by combining agency and resource dependence theories, thus providing a joint theoretical lens to study determinants of CEO pay and its alignment with firm performance. A large sample, comprising 4,859 firm observations across the US S&P1,500 from 2007 to 2010, was collected from Compustat, ExecuComp, and RiskMetricks databases. Four separate proxies for firm centrality were measured: Degree, Eigenvector, Betweenness, and Closeness centrality. Thomson Reuters ASSET4 Corporate Governance Index (TRACGI) was used to measure governance quality. The resulting unbalanced panel data were then analyzed using random effects mixed models. Results show that director interlocks are positively associated with CEO pay. This association is moderated by corporate governance quality. The study shows that in low governance conditions, there is a more significant positive association between network centrality and CEO pay when compared to high governance conditions. Thus, governance quality attenuates the positive association between firm interlocks and CEO pay. A number of additional analyses were conducted, confirming that results are not dependent on extraneous factors such as the impact of the global financial crisis or firms operating in the finance sector. This study makes several contributions. First, it contributes to theory by providing a new theoretical lens resulting from the interconnection of two theories to studying determinants of CEO pay. Second, it contributes to practice by informing governments, policy makers, and auditors of the significant impact of director interlocks on CEO pay in addition to corporate governance. Finally, this study makes a methodological contribution by applying a more comprehensive measure of corporate governance to studying CEO pay and director interlocks than that incorporated in prior research.

description: In this paper we introduce the polynomials $\{d_n^{(r)}(x)\}$ and $\{D_n^{(r)}(x)\}$ given by $d_n^{(r)}(x)=\sum_{k=0}^n\binom{x+r+k}k\binom{x-r}{n-k} \ (n\ge 0)$, $D_0^{(r)}(x)=1,\ D_1^{(r)}(x)=x$ and $D_{n+1}^{(r)}(x)=xD_n^{(r)}(x)-n(n+2r)D_{n-1}^{(r)}(x)\ (n\ge 1).$ We show that $\{D_n^{(r)}(x)\}$ are orthogonal polynomials for $r>-\frac 12$, and establish many identities for $\{d_n^{(r)}(x)\}$ and $\{D_n^{(r)}(x)\}$, especially obtain a formula for $d_n^{(r)}(x)^2$ and the linearization formulas for $d_m^{(r)}(x)d_n^{(r)}(x)$ and $D_m^{(r)}(x)D_n^{(r)}(x)$. As an application we extend recent work of Sun and Guo.

description: The aim of this paper is to develop a probabilistic model for a cold standby system that consists of an imperfect switching device and a servicing facility. The model aims to address the issue of unexpected random failures of the switch by implementing preventive maintenance measures. The system has two identical units. It starts with one unit in active operation and another unit in cold standby mode. In standby mode the unit remains in perfect state. No failure is allowed in standby mode. As the operating unit fails, the standby unit needs to be switched into operation, to keep the system working. A servicing facility is present in the system to perform necessary servicing related tasks. The servicing facility referred to as the server, also takes care of all necessary remedial activities like preventive maintenance and repairs. The switch used as switching mechanism to place the standby unit into operation may found imperfect when needed. Similarly, the server too can fail while doing job. A preventive maintenance scheme is used for the switch whereas treatment is given to server. The method of semi-Markov process and regenerative point technique is used for model developing and solving, respectively. The expressions are derived to determine different system performance measures such as mean time to system failure, availability, busy period, expected number of preventive maintenances and the profit. The distributions of random time elapsed in repairs, replacements, preventive maintenances and treatments are general. This study highlights the usefulness of switch’s preventive maintenance in long run. To study the asymptotic behavior of the system model, all the expressions for system performance measures are obtained in steady state. A simulation study is conducted using a presumed data set and assuming a Weibull probability distribution. The numerical results are shown in tabular form. The simulation results serve to highlight the significance of preventive maintenance for the switch. The findings of the paper can provide guidelines to the people engaged in designing, framing and implementing standby switching systems in real applications.

description: The future of computer systems will not be dominated by personal computer like hardware platforms but by embedded and cyber-physical systems assisting humans in a hidden but omnipresent manner. These pervasive computing devices can, for example, be utilized in the home automation sector to create sensor/ actuator networks supporting the inhabitants of a house in everyday life. The efficient usage of resources is an important topic at design time and operation time of mobile embedded and cyber-physical systems. Therefore, this thesis presents methods which allow an efficient use of energy and processing resources in sensor/actuator networks. These networks comprise different nodes cooperating for a “smart” joint control function. Sensor/actuator nodes are typical cyber-physical systems comprising sensors/actuators and processing and communication components. Processing components of today’s sensor nodes can comprise many-core chips. This thesis introduces new methods for optimizing the code and the application mapping of the aforementioned systems and presents novel results with regard to design space explorations for energy-efficient and embedded many-core systems. The considered many-core systems are graphics processing units. The application code for these graphics processing units is optimized for a particular platform variant with the objectives of minimal energy consumption and/or of minimal runtime. These two objectives are targeted with the utilization of multi-objective optimization techniques. The mapping optimizations are realized by means of multi-objective design space explorations. Furthermore, this thesis introduces new techniques and functions for a resource-efficient middleware design employing service-oriented architectures. Therefore, a service-oriented architecture based middleware framework is presented which comprises a lightweight service orchestration. In addition to that, a flexible resource management mechanism will be introduced. This resource management adapts resource utilization and services to an environmental context and provides methods to reduce the energy consumption of sensor nodes.
