description: Echo state network (ESN), a kind of recurrent neural networks, consists of a fixed reservoir in which neurons are connected randomly and recursively and obtains the desired output only by training output connection weights. First-order reduced and controlled error (FORCE) learning is an online supervised training approach that can change the chaotic activity of ESNs into specified activity patterns. This paper proposes a composite FORCE learning method based on recursive least squares to train ESNs whose initial activity is spontaneously chaotic, where a composite learning technique featured by dynamic regressor extension and memory data exploitation is applied to enhance parameter convergence. The proposed method is applied to a benchmark problem about predicting chaotic time series generated by the Mackey-Glass system, and numerical results have shown that it significantly improves learning and prediction performances compared with existing methods.

description: As a major breakthrough in artificial intelligence and deep learning, Convolutional Neural Networks have achieved an impressive success in solving many problems in several fields including computer vision and image processing. Real-time performance, robustness of algorithms and fast training processes remain open problems in these contexts. In addition object recognition and detection are challenging tasks for resource-constrained embedded systems, commonly used in the industrial sector. To overcome these issues, we propose a dimensionality reduction framework based on Proper Orthogonal Decomposition, a classical model order reduction technique, in order to gain a reduction in the number of hyperparameters of the net. We have applied such framework to SSD300 architecture using PASCAL VOC dataset, demonstrating a reduction of the network dimension and a remarkable speedup in the fine-tuning of the network in a transfer learning context.

description: We present a non-perturbative regularization scheme for Quantum Field Theories which amounts to an embedding of the originally unregularized theory into a spacetime with an extra compactified dimensions of length L ~ Lambda^{-1} (with Lambda an ultraviolet cutoff), plus a doubling in the number of fields, which satisfy different periodicity conditions and have opposite Grassmann parity. The resulting regularized action may be interpreted, for the fermionic case, as corresponding to a finite-temperature theory with a supersymmetry, which is broken because of the boundary conditions. We test our proposal in a perturbative calculation (the vacuum polarization graph for a D-dimensional fermionic theory) and in a non-perturbative one (the chiral anomaly).

description: We consider the vertical motion of a free falling ball bouncing elastically on a racket moving in the vertical direction according to a regular $1$-periodic function $f$. For fixed coprime $p,q$ we study existence, stability in the sense of Lyapunov and multiplicity of $p$ periodic motions making $q$ bounces in a period. If $f$ is real analytic we prove that one periodic motion is unstable and give some information on the set of these motions.

description: We combined high-resolution Fourier-transform spectroscopy and large-scale electronic structure calculation to study energy and radiative properties of the high-lying (3)1Π and (5)1Σ+ states of the RbCs molecule. The laser-induced (5)1Σ+(4)1Σ+(3)1Π-A(2)1Σ+ b(1)3Π fluorescence (LIF) spectra were recorded by the Bruker IFS-125(HR) spectrometer in the frequency range ν 5500 to 10000cm-1 with the instrumental resolution of 0.03 cm-1. The rotational assignment of the observed LIF progressions, which exhibit irregular vibrational-rotational spacing due to strong spin-orbit interaction between A1Σ+ and b3(Π) states was based on the coincidences between observed and calculated energy differences. The required rovibronic term values of the strongly perturbed A-b complex have been calculated by a coupled-channels approach for both 85Rb133Cs and 87Rb133Cs isotopologs with accuracy of about 0.01 cm-1, as demonstrated in A. Kruzins et al. [J. Chem. Phys. 141, 184309 (2014)]. The experimental energies of the upper (3)1(Π) and (5)1Σ+ states were involved in a direct-potential-fit analysis performed in the framework of inverted perturbation approach. Quasirelativistic ab initio calculations of the spin-allowed (3)1Π,(5)1Σ+- (1-4)1Σ+(1-3)1Π transition dipole moments were performed. Radiative lifetimes and vibronic branching ratios of radiative transitions from the (3)1Π and (5)1Σ+ states were evaluated. To elucidate the origin of the Λ-doubling effect in the (3)1Π state, the angular coupling (3)1Π-(1-5)1Σ+ electronic matrix elements were calculated and applied for the relevant q-factors estimate. The intensity distributions simulated for the particular (5)1Σ+(3)1Π-A-b LIF progressions have been found to be remarkably close to their experimental counterparts.

description: The paradox of the divergence of the resonant scattering cross section of a cylinder with the permittivity equals minus unity and vanishing radius (R) irradiated by a monochromatic electromagnetic wave is discussed. Within the framework of the exact solution of the Maxwell equations, the divergence at the specified conditions is caused by the overlap of all but one multipolar resonances. It is shown that the paradox is caused by the too straightforward analysis of the expression for the cross section, which has a singularity at this point. To resolve the singularity, one must, first, generalize the problem formulation, taking into account the final linewidth of the incident wave, and then perform the correct sequence of limit transitions. The application of this approach gives rise to the vanishing cross section at the vanishing R. It ruins the expectations to employ such a cylinder as a superscatterer but simultaneously open a door to counterintuitive effects both in far and near field zones related to unusual size dependences of the scattered fields at small but finite R.

description: We study neutrino emission from the remnant of an inspiraling binary neutron star following coalescence. The mass of the merged remnant is likely to exceed the stability limit of a cold, rotating neutron star. However, the angular momentum of the remnant may also approach or even exceed the Kerr limit, J/M^2 = 1, so that total collapse may not be possible unless some angular momentum is dissipated. We find that neutrino emission is very inefficient in decreasing the angular momentum of these merged objects and may even lead to a small increase in J/M^2. We illustrate these findings with a post-Newtonian, ellipsoidal model calculation. Simple arguments suggest that the remnant may form a bar mode instability on a timescale similar to or shorter than the neutrino emission timescale, in which case the evolution of the remnant will be dominated by the emission of gravitational waves.

description: We studied time resolution and response power dependence of three terahertz detectors based on significantly different types of field effect transistors. We analyzed the photoresponse of custom-made Si junctionless FETs, Si MOSFETs and GaAs-based high electron mobility transistors detectors. Applying monochromatic radiation of high power, pulsed, line-tunable molecular THz laser, which operated at frequencies in the range from 0.6-3.3 THz, we demonstrated that all these detectors have at least nanosecond response time. We showed that detectors yield a linear response in a wide range of radiation power. At high powers the response saturates varying with radiation power P as $U = R_0 P/(1+P/P_s)$, where $R_0$ is the low power responsivity, $P_s$ is the saturation power. We demonstrated that the linear part response decreases with radiation frequency increase as $R_0 \propto f^{-3}$, whereas the power at which signal saturates increases as $P_s \propto f^3$. We discussed the observed dependences in the framework of the Dyakonov-Shur mechanism and detector-antenna impedance matching. Our study showed that FET transistors can be used as ultrafast room temperature detectors of THz radiation and that their dynamic range extends over many orders of magnitude of power of incoming THz radiation. Therefore, when embedded with current driven read out electronics they are very well adopted for operation with high power pulsed sources.

Wage and employment determination in agricultural labour markets in India
Creators: name: Datt, Gaurav
Publisher: name: The Australian National University
Year: 1989

description: The thesis is concerned with the problem of wage and employment determination in the (casual) agricultural labour markets of India. It is argued that the extant theories of wage determination poorly accord with the stylized facts of the Indian situation. An alternative perspective on agricultural labour markets is developed, where wage determination at the village level is interpreted as the outcome of tacit collective bargaining between village labourers and employers. It is argued that cooperative behaviour, necessary to support such collective bargaining, can often be sustained through the operation of certain informal social sanctions against wage cutting behaviour. With an asymmetric Nash framework, a theoretical model of the village-level market for agricultural labour is developed, which simultaneously determines the agricultural wage rate, the level of employment and the employers' profits. The model is consistent with the existence of involuntary unemployment, while also explaining variability of wages. In the extended version of the model, male and female labourers are introduced as separate bargaining parties. The extended model provides a possible explanation for the existence of gender wage (and employment) disparities. Both the basic and extended models are econometrically estimated for ten villages in central, south and west India, using data collected by the International Crops Research Institute for Semi-Arid Tropics (Hyderabad). Bargaining powers of employers', male and female labourers (interpreted as the coefficients on their net gains from agreement) are estimated. The results show significant inequalities of bargaining power between employers and labourers, and between male and female labourers. Simulations based on the estimated models indicate that the observed inequalities of bargaining power are a quantity decisive influence on wage, employment and profit outcomes in the village labour markets.

description: The study of the dynamics of a two-body system in modified gravity constitutes a more complex problem than in Newtonian gravity. Numerical methods are typically needed to solve the equations of geodesics. Despite the complexity of the problem, the study of a two-body system in $f(R)$ gravity leads to a new exciting perspective hinting the right strategy to adopt in order to probe modified gravity. Our results point out some differences between the {\em semiclassical} (Newtonian) approach, and the {\em relativistic} (geodesic) one thus suggesting that the latter represents the best strategy for future tests of modified theories of gravity. { Finally, we have also highlighted the capability of forthcoming observations to serve as smoking gun of modified gravity revealing a departure from GR or further reducing the parameter space of $f(R)$ gravity}. \keywords{$f(R)$ gravity \and binary system \and geodesics \and precession

description: Based on the old results of Cho, Soh, Park and Yoon, it is shown how higher m + n dimensional pure gravitational actions restricted to AdS_m times S^n backgrounds admit a holographic reduction to a lower m-dimensional Yang-Mills-like gauge theory of diffeomorphisms of S^n interacting with a charged non-linear sigma model plus boundary terms by a simple tuning of the AdS_m-throat and S^n-radius sizes. After performing a harmonic expansion of the fields with respect to the internal coordinates and a subsequent integration one obtains an m-dimensional effective action involving an infinite-component field theory. The supersymmetrization program can be carried out in a straighforward fashion.

description: The key underlying question of this dissertation is whether and how business actors are able to use their heightened mobility to affect electoral outcomes and constrain the policy choices of elected officials. Focusing on cases of interstate corporate headquarters (HQ) relocation and its effects on gubernatorial elections, this dissertation investigates the electoral effects of HQ relocation and its implications for policy. The first chapter examines electoral effects of interstate HQ relocation. My analysis shows that HQ relocation generates electoral responses but in an asymmetrical manner between HQ inflow and HQ outflow: when HQ relocate in, citizens tend to vote for the incumbent party in gubernatorial elections, expecting similar positive events to continue. When HQ relocate out, voters increase support for the Republican Party in an effort to lower the chances of recurrence. This is because of the pervasive belief that the Democratic Party tends to pursue the main policy drivers of HQ outflow---high corporate tax rates and less- friendly business environments. Building upon the findings in the first chapter, the second chapter investigates whether the asymmetric responses of voters to HQ relocation gives rise to different practices in offering lucrative tax incentives depending on the partisanship of the elected officials. The analysis provides evidence that mobile firms such as multinational corporations and firms operating in multiple states, pay lower effective corporate tax rates under Democratic governors than Republican governors. Lastly, the third chapter investigates microfoundtional support for partisan blame attributions in the wake of HQ relocation using a survey experiment. I find that the effects of party label only prevail in the aftermath of an HQ outflow since voters believe that Democrat politicians tend to support high corporate tax rates and less-friendly business environments, which, these voters believe, push corporate HQ out of their states. The findings of my dissertation have implications for the political economy of business-government relationships, broad debates on the effects of economic globalization on policy levers of governments, and our understanding of electoral accountability.

description: Formic acid (HCOOH) and carbon dioxide (CO2) are simple species that have been detected in the interstellar medium. The solid-state formation pathways of these species under experimental conditions relevant to prestellar cores are primarily based off of weak infrared transitions of the HOCO complex and usually pertain to the H2O-rich ice phase, and therefore more experimental data are desired. In this article, we present a new and additional solid-state reaction pathway that can form HCOOH and CO2 ice at 10 K 'non-energetically' in the laboratory under conditions related to the "heavy" CO freeze-out stage in dense interstellar clouds, i.e., by the hydrogenation of an H2CO:O2 ice mixture. This pathway is used to piece together the HCOOH and CO2 formation routes when H2CO or CO reacts with H and OH radicals. Temperature programmed desorption - quadrupole mass spectrometry (TPD-QMS) is used to confirm the formation and pathways of newly synthesized ice species as well as to provide information on relative molecular abundances. Reflection absorption infrared spectroscopy (RAIRS) is additionally employed to characterize reaction products and determine relative molecular abundances. We find that for the conditions investigated in conjunction with theoretical results from the literature, H+HOCO and HCO+OH lead to the formation of HCOOH ice in our experiments. Which reaction is more dominant can be determined if the H+HOCO branching ratio is more constrained by computational simulations, as the HCOOH:CO2 abundance ratio is experimentally measured to be around 1.8:1. H+HOCO is more likely than OH+CO (without HOCO formation) to form CO2. Isotope experiments presented here further validate that H+HOCO is the dominant route for HCOOH ice formation in a CO-rich CO:O2 ice mixture that is hydrogenated. These data will help in the search and positive identification of HCOOH ice in prestellar cores.

description: Energy harvesting is an important developing technology for a new generation of self-powered sensor networks. This paper demonstrates the significant improvement in the piezoelectric energy harvesting performance of barium titanate by forming highly aligned porosity using freeze casting. Firstly, a finite element model demonstrating the effect of pore morphology and angle with respect to poling field on the poling behaviour of porous ferroelectrics was developed. A second model was then developed to understand the influence of microstructure-property relationships on the poling behaviour of porous freeze cast ferroelectric materials and their resultant piezoelectric and energy harvesting properties. To compare with model predictions, porous barium titanate was fabricated using freeze casting to form highly aligned microstructures with excellent longitudinal piezoelectric strain coefficients, d 33. Both model and experimental data indicated that introducing porosity provides a large reduction in the permittivity () of barium titanate, which leads to a substantial increase in energy harvesting figure of merit, , with a maximum of 3.79 pm2 N-1 for barium titanate with 45 vol.% porosity, compared to only 1.40 pm2 N-1 for dense barium titanate. Dense and porous barium titanate materials were then used to harvest energy from a mechanical excitation by rectification and storage of the piezoelectric charge on a capacitor. The porous barium titanate charged the capacitor to a voltage of 234 mV compared to 96 mV for the dense material, indicating a 2.4-fold increase that was similar to that predicted by the energy harvesting figures of merit.

description: Numerous optical phenomena and applications have been enabled by nanophotonic structures. Their current fabrication from high refractive index dielectrics, such as silicon or gallium phosphide, pose restricting fabrication challenges, while metals, relying on plasmons and thus exhibiting high ohmic losses, limit the achievable applications. Here, we present an emerging class of layered so-called van der Waals (vdW) crystals as a viable nanophotonics platform. We extract the dielectric response of 11 mechanically exfoliated thin-film (20-200 nm) van der Waals crystals, revealing high refractive indices up to n = 5, pronounced birefringence up to $Δ$n = 3, sharp absorption resonances, and a range of transparency windows from ultraviolet to near-infrared. We then fabricate nanoantennas on SiO$_2$ and gold utilizing the compatibility of vdW thin films with a variety of substrates. We observe pronounced Mie resonances due to the high refractive index contrast on SiO$_2$ leading to a strong exciton-photon coupling regime as well as largely unexplored high-quality-factor, hybrid Mie-plasmon modes on gold. We demonstrate further vdW-material-specific degrees of freedom in fabrication by realizing nanoantennas from stacked twisted crystalline thin-films, enabling control of nonlinear optical properties, and post-fabrication nanostructure transfer, important for nano-optics with sensitive materials.

Three Essays on the Political Economy of Corporate Bailouts
Creators: Smith, Michael
Publisher: name: Columbia University
Year: 2014
Subjects: subject: Political science
subject: FOS: Political science
subject: International relations

description: This dissertation is comprised of three papers exploring the causes of the likelihood and distribution of corporate bailouts. The first paper explores why some distressed firms receive bailouts while others do not. It argues that political partisanship plays a key role: left-wing governments are more likely to authorize bailouts on average, and are particularly more likely to save employee-rich firms. The theory is tested using a new dataset comprised of financially distressed firms, a subset of which receive bailouts. The second paper examines why bailouts are concentrated in a particular subset of industrial sectors. The primary argument is again political partisanship: left-wing governments seek to protect firms in sectors that have the most employees. Alternative explanations, including the impact of globalization and alternative forms of social protection, are also considered. The theory is shown to hold using a new dataset comprised of comprehensive counts of bailouts by sector across the European Economic Area. The final paper examines the nature of public opinion regarding bailouts. The paper undermines the standing assumption that bailouts are largely unpopular by instead showing that public support varies by context and is in some instances supportive. Using observational data in conjunction with survey experiments, individual characteristics, including partisanship and material self-interest, as well as firm-specific characteristics, including the relevance of the firm to the national economy, are shown to drive public support for bailouts.

description: Recently, efforts have been made to standardize signal phase and timing (SPaT) messages. These messages contain signal phase timings of all signalized intersection approaches. This information can thus be used for efficient motion planning, resulting in more homogeneous traffic flows and uniform speed profiles. Despite efforts to provide robust predictions for semi-actuated signal control systems, predicting signal phase timings for fully-actuated controls remains challenging. This paper proposes a time series prediction framework using aggregated traffic signal and loop detector data. We utilize state-of-the-art machine learning models to predict future signal phases' duration. The performance of a Linear Regression (LR), a Random Forest (RF), and a Long-Short-Term-Memory (LSTM) neural network are assessed against a naive baseline model. Results based on an empirical data set from a fully-actuated signal control system in Zurich, Switzerland, show that machine learning models outperform conventional prediction methods. Furthermore, tree-based decision models such as the RF perform best with an accuracy that meets requirements for practical applications.
The Emergence of a Black Hole in Supernova Explosions

description: We present results from a fully relativistic investigation of matter fallback in a supernova, assuming that the central compact star is a black hole (BH). Our goal is to answer the following questions: can we infer from the light curve whether a stellar black hole (BH) has formed in the aftermath of a supernova explosion ? Did SN1897A produce a BH and, if so, when will the hole become detectable ? We show that it should not be possible to infer the presence of a BH in the remnant for another several hundred to a thousand years. In the case of SN1987A, we estimate the BH luminosity to be $L\simeq 5\times 10^{34}$ erg s$^{-1}$, which is well below the present day bolometric luminosity of the remnant ($\sim 10^{36}erg/s$; Suntzeff 1997).

description: We present a density-matrix embedding theory (DMET) study of the one-dimensional Hubbard-Holstein model, which is paradigmatic for the interplay of electron-electron and electron-phonon interactions. Analyzing the single-particle excitation gap, we find a direct Peierls insulator to Mott insulator phase transition in the adiabatic regime of slow phonons in contrast to a rather large intervening metallic phase in the anti-adiabatic regime of fast phonons. We benchmark the DMET results for both on-site energies and excitation gaps against density-matrix renormalization group (DMRG) results and find excellent agreement of the resulting phase boundaries. We also compare the fully quantum treatment of phonons against the standard Born-Oppenheimer (BO) approximation. The BO approximation gives qualitatively similar results to DMET in the adiabatic regime, but fails entirely in the anti-adiabatic regime, where BO predicts a sharp direct transition from Mott to Peierls insulator, whereas DMET correctly shows a large intervening metallic phase. This highlights the importance of quantum fluctuations in the phononic degrees of freedom for metallicity in the one-dimensional Hubbard-Holstein model.

description: The countably paracompact normal spaces were characterised by Dowker and Katětov in terms of an insertion property. Dowker also characterised them by normality of their product with the closed unit interval. Michael used the Dowker-Katětov insertion property to motivate his selection characterisation of these spaces. Morita extended in a natural way Dowker's product characterisation to all $τ$-paracompact normal spaces. In this paper, we look at these results from the point of view of open relations. Insertions and selections are equivalent for such relations. Furthermore, we obtain a natural characterisation of $τ$-paracompact normal spaces in terms of selections for convex-valued open relations. Based on this characterisation, we give simple alternative proofs of the above mentioned results. Other applications are obtained as well.
Astrology in Thailand: the future and recollection of the past
Creators: name: Cook, Nerida M.
Publisher: name: The Australian National University
Year: 1989

description: This is a study of astrology in Bangkok, based on fieldwork in 1982-3 and a short return visit in August-October 1984. The research was based on the activities of two astrological associations, and incorporated information from formal and informal interviews with a range of practising astrologers and other fortunetellers about their role in contemporary Bangkok society. Other research activities included observations of fortune-telling consultations and discussions with clients. The aim of the research was to discover what the modern role of astrology is in Bangkok, and to attempt to assess what was happening to this aspect of Thai belief under modern urban conditions. It was also an exploration of the relationship of astrology to other elements of the Thai world-view, since this has not previously been the subject of investigation; and further included an examination of the Thai astrological view of the past, since history was found to be a prominent interest of astrologers. The argument of this thesis is also about time, since I suggest that Thai astrology is basically a system of interpretation of the meanings discoverable in temporal experience. Some portion of the thesis is therefore devoted to the analysis of the temporal experience underlying Thai astrology both as a system and in the way that astrology is dependent on temporal context for its very practice. It is suggested that the use made of astrology in Thailand shows that qualitative views of temporal experience are not incompatible with linear concepts of time. In this thesis it is argued that Thai astrology has continued among some groups in Thai society as an intrinsic aspect of a world view concerned with auspiciousness, power and legitimacy. This is an inheritance from Thai astrology's elite background, at least in the sophisticated level of astrology investigated here. The fact that Thai astrology is eagerly supported by some in Thai society while as keenly refuted by others is discussed to show that the opposition to astrology in Bangkok is not just a repetition of the kinds of arguments concerning credibility and determinism which has been found in the West, but rather a debate with distinctively Thai concerns about the adequacy of religious explanation in Buddhism and about the development of a rationalised and democratic society. It is therefore suggested that astrology in Thailand has become involved in deeper political and philosophical conflicts which are of ongoing social and political significance in contemporary Bangkok, and that this is an important factor in understanding the present role of astrology in Bangkok.
Does the Tachyon Matter?

description: We study time-dependent solutions of Einstein-Maxwell gravity in four dimensions coupled to tachyon matter--the Dirac-Born-Infeld Lagrangian that provides an effective description of a decaying tachyon on an unstable D-brane in string theory. Asymptotically, the solutions are similar to the recently studied space-like brane solutions and carry S-brane charge. They do not break the Lorentzian R-symmetry. We study the tachyon matter as a probe in such a background and analyze its backreaction. For early/late times, the tachyon field has a constant energy density and vanishing pressure as in flat space. On the other hand, at intermediate times, the energy density of the tachyon diverges and produces a space-like curvature singularity.

description: This dissertation encompasses three studies on issues of model-data fit methods for latent variable models implemented in modern educational measurement. The first study proposes a new statistic to test the mean-difference of the ability distributions estimated based on the responses of a group of examinees, which can be used to detect aberrant responses of a group of test-takers. The second study is a review of the current model-data fit indexes used for cognitive diagnostic models. Third study introduces a modified version of an existing item fit statistic so that the modified statistic has a known chi-square distribution. Lastly, a discussion of the three studies is given, including the studies’ limitations and thoughts on the direction of future research.
