description: Stellar kinematics provides the key to understanding the formation process and dynamical evolution of stellar systems. Here, we present a kinematic study of the massive star-forming region W4 in the Cassiopeia OB6 association using the Gaia Data Release 2 and high-resolution optical spectra. This star-forming region is composed of a core cluster (IC 1805) and a stellar population distributed over 20 pc, which is a typical structural feature found in many OB associations. According to a classical model, this structural feature can be understood in the context of the dynamical evolution of a star cluster. The core-extended structure exhibits internally different kinematic properties. Stars in the core have an almost isotropic motion, and they appear to reach virial equilibrium given their velocity dispersion (0.9 +/- 0.3 km/s) comparable to that in a virial state (~0.8 km/s). On the other hand, the distributed population shows a clear pattern of radial expansion. From the N-body simulation for the dynamical evolution of a model cluster in subvirial state, we reproduce the observed structure and kinematics of stars. This model cluster experiences collapse for the first 2 Myr. Some members begin to radially escape from the cluster after the initial collapse, eventually forming a distributed population. The internal structure and kinematics of the model cluster appear similar to those of W4. Our results support the idea that the stellar population distributed over 20 pc in W4 originate from the dynamical evolution of IC 1805.

Optimum test Strategy for SoCs including wrapper and TAM design and optimization
Creators: name: Ebadi, Zahra Sadat
Publisher: name: University of British Columbia
Year: 2009

description: Using the large number of transistors available on a chip, designers have already managed to put an entire system on a single chip. These are referred to as System-on-a-Chip (SoC). Being able to rapidly develop, manufacture, test, debug and verify complex SoCs is crucial for the continued success of the electronics industry. In the problem of SoC test integration three issues need to be addressed: wrapper design, TAM design and test scheduling. In this thesis, a novel wrapper design method is introduced to minimize the core test time, the number of test I/O pins and the required ATE memory. While previous methods for wrapper design only minimize the test time, the proposed method considers all of these factors in the test cost. Also a novel TAM based on time domain multiplexing (TDM-TAM) is introduced. This TAM is P1500 compatible and uses a P1500 wrapper. Its characteristics are flexibility, scalability, and reconfigurability.

description: The transport of scalar quantities passively advected by velocity fields with a small-scale component can be modeled at meso-scale level by means of an effective drift and an effective diffusivity, which can be determined by means of multiple-scale techniques. We show that the presence of a weak large-scale flow induces interesting effects on the meso-scale scalar transport. In particular, it gives rise to non-isotropic and non-homogeneous corrections to the meso-scale drift and diffusivity. We discuss an approximation that allows us to retain the second-order effects caused by the large-scale flow. This provides a rather accurate meso-scale modeling for both asymptotic and pre-asymptotic scalar transport properties. Numerical simulations in model flows are used to illustrate the importance of such large-scale effects.

description: Atrial fibrillation (AF) is the most prevalent arrhythmia and is associated with a five-fold increase in stroke risk. Many individuals with AF go undetected. These individuals are often asymptomatic. There are ongoing debates on whether mass screening for AF is to be recommended. However, there is incentive in performing screening for specific at risk groups such as individuals suspected of sleep-disordered breathing where an important association between AF and obstructive sleep apnea (OSA) has been demonstrated. We introduce a new methodology leveraging digital biomarkers and recent advances in artificial intelligence (AI) for the purpose of mass AF diagnosis. We demonstrate the value of such methodology in a large population sample at risk of sleep disordered breathing. Four databases, totaling n=3,088 patients and p=26,913 hours of ECG raw data were used. Three of the databases (n=125, p=2,513) were used for training a machine learning model in recognizing AF events from beat-to-beat interval time series. The visit 1 of the sleep heart health study database (SHHS1, n=2,963, p=24,400) consists of overnight polysomnographic (PSG) recordings, and was considered as the test set. In SHHS1, expert inspection identified a total of 70 patients with a prominent AF rhythm. Model prediction on the SHHS1 showed an overall Se=0.97,Sp=0.99,NPV=0.99,PPV=0.67 in classifying individuals with or without prominent AF. PPV was non-inferior (p=0.03) for individuals with an apnea-hypopnea index (AHI) > 15 versus AHI < 15. Over 22% of correctly identified prominent AF rhythm cases were not documented as AF in the SHHS1. Individuals with prominent AF can be automatically diagnosed from an overnight single channel ECG recording, with an accuracy unaffected by the presence of OSA. AF detection from overnight ECG recording revealed a large proportion of undiagnosed AF and may enhance the phenotyping of OSA.

Production Economics

description: A socio-economic analysis of the farms in four villages of the Dikodougou region (North of Cote d'Ivoire) reviews two debates about the evolution of the farming systems in sub-Saharan Africa. Firstly, the two opposing views in the controversy "Boserup versus Malthus" are complements rather than opposites. In a first phase, demographic pressure causes Malthusian mechanisms (proliferation of weeds, deterioration of the bio-physical environment, of global fertility and of the profitability of the traditional production system) generating favourable conditions for the adoption of ox-drawn farming. In a second phase, the alternation of the production system illustrates well the Boserupian response to a situation where the traditional system is not adapted to the new socio-economic conditions. Secondly, the economic analysis proposes to review the debate "competition versus complementarity" between cotton and food crops. The competition thesis seems only valid for not mechanised farms, where cotton competes with food crops for labour. However, the second phase of the evolution of the production systems (utilisation of pesticides and fertilisers, substitution of manual farming by ox-drawn farming) is possible thanks to the favourable conditions (access to pesticides, fertilisers, credit and know-how) generated by the CIDT (Compagnie Ivoirienne de Developpement des Textiles).

description: Some of the crucial assumptions of applied welfare economics do not hold any longer in the case of agricultural biotechnology innovations. We review some modifications to the conventional methodologies measuring the size and distribution of agricultural research benefits, which are critical for the assessment of the economic impact of agricultural biotechnology in the European Union. While some modifications are related to the specific features of modern agricultural biotechnology and technology adoption, others are related to the specific institutional settings of the European Union's Common Agricultural Policy and commodity markets.

description: We report a uniaxial-pressure study on the magnetisation of single crystals of the bilayer perovskite Sr3Ru2O7, a metamagnet close to a ferromagnetic instability. We observed that the application of a uniaxial pressure parallel to the c-axis induces ferromagnetic ordering with a Curie temperature of about 80 K and critical pressures of about 4 kbar or higher. This value for the critical pressure is even higher than the value previously reported (~ 1 kbar), which might be attributed to the difference of the impurity level. Below the critical pressure parallel to the c-axis, the metamagnetic field appears to hardly change. We have also found that uniaxial pressures perpendicular to the c-axis, in contrast, do not induce ferromagnetism, but shift the metamagnetic field to higher fields.

description: A topological insulator doped with random magnetic impurities is studied. The system is modelled by the Kane-Mele model with a random spin exchange between conduction electrons and magnetic dopants. The dynamical mean field theory for disordered systems is used to investigate the electron dynamics. The magnetic long-range order and the topological invariant are calculated within the mean field theory. They reveal a rich phase diagram, where different magnetic long-range orders such as antiferromagnetic or ferromagnetic one can exist in the metallic or insulating phases, depending on electron and magnetic impurity fillings. It is found that insulator only occurs at electron half filling, quarter filling and when electron filling is equal to magnetic impurity filling. However, non-trivial topology is observed only in half-filling antiferromagnetic insulator and quarter-filling ferromagnetic insulator. At electron half filling, the spin Hall conductance is quantized and it is robust against magnetic doping, while at electron quarter filling, magnetic dopants drive the ferromagnetic topological insulator to ferromagnetic metal. The quantum anomalous Hall effect is observed only at electron quarter filling and dense magnetic doping.
Scheduling techniques for flexible semiconductor manufacturing tools
Creators: name: Rostani, Shadi
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis, we introduce Residency Constraints for cluster tools. A residency constraint is a limit on how long raw material can reside on either a processing module or the robot after the process is finished. Like a deadline, it specifies a point in time by which a task must be finished. However, unlike a deadline, the point in time is no longer a fixed point, and is determined dynamically when the system runs based on the completion time of other tasks. Our work is the first to attempt to address different forms of residency constraints in cluster tools. We investigate different models of cluster tools, and provide different scheduling techniques for each model. the first model that we investigate is a single-route model, which assumes that all wafers go through the same processing visits. First, we assume that a residency constraint is only allowed on processing modules, and provide a scheduling technique that searches the time and resource domains for an optimal solution. Then, we allow Residency Constraints on both the processing modules and the robot. For this model, we introduce another technique that uses a special kind of Linear Programming and a branch-and-bound method to search for the optimal schedule. In the next model, we use the buffer module to hold the partially processed materials and free the resources to improve the performance of the system. Our experiment shows that these techniques find the optimal schedule in a reasonable amount of time. The last model that we investigate is a multi-route model that supports the production of different products i n the same tool configuration. We provide a greedy algorithm that finds a near-optimal schedule for residency-free cases. For the residency-aware model, we provide both optimal and nearoptimal scheduling techniques. We use Simulated Annealing for finding the near-optimal schedule, and provide several optimization techniques to improve the quality of the near-optimal solution.

description: We show that a large collection of statistical mechanical systems with quadratically represented Hamiltonians on the complete graph can be extended to infinite exchangeable processes. This extends a known result for the ferromagnetic Curie--Weiss Ising model and includes as well all ferromagnetic Curie--Weiss Potts and Curie--Weiss Heisenberg models. By de Finetti's theorem, this is equivalent to showing that these probability measures can be expressed as averages of product measures. We provide examples showing that ``ferromagnetism'' is not however in itself sufficient and also study in some detail the Curie--Weiss Ising model with an additional 3-body interaction. Finally, we study the question of how much the antiferromagnetic Curie--Weiss Ising model can be extended. In this direction, we obtain sharp asymptotic results via a solution to a new moment problem. We also obtain a ``formula'' for the extension which is valid in many cases.

description: The literature on the evolution of farming systems in West Africa shows a large diversity of general theories on rural development. The purpose of this study is to revisit the theses of Malthus and Boserup and empirically test them on a case study of Northern Cote d'Ivoire. We have at our disposal a database spread over three agricultural seasons (1995-1998) and four villages. These villages differ strongly regarding their population density and historical genesis. The comparison between these villages permits us to track down their stage in the evolution of farming systems and to identify population pressure as a key factor of the evolution of farming systems and to identify population pressure as a key factor of the evolution process of farms. Our empirical analysis shows that boserupian and Malthusian processes coexist, rather than contrast. Labor is the key factor for escaping Malthusian mechanisms and induces Boserupian innovations that are crucial to the evolution trajectory of farms.

description: We consider the interaction between a single-mode quantized perturbing external field and a Bose-Einstein condensate (BEC) out of equilibrium. The usual Rabi type oscillations between the ground and the excited state of the coherent topological modes are observed with a Rabi frequency modified by the two-body atomic interactions. Taking into account the granular structure of the external perturbing field reveals the well know phenomena of collapse and revival of the Rabi oscillations. In particular we find that atomic interactions reduce the Rabi frequency and also affect the collapse and revival sequence.

description: Room and high temperature mechanical properties of reactive magnetron sputtered TaSiN coatings were measured using nanoindentation (between 25C and 500C). Fracture toughness was also evaluated at a similar temperature range using the micropillar splitting method. The influence of the nitrogen concentration on the evolving phases and microstructure of the TaSiN coatings, before and after the high temperature testing, were examined by X-ray diffraction (XRD) and transmission electron microscopy (TEM) analysis. XRD spectra showed broad peaks with hexagonal $γ$-Ta2N as the main phase, with the cubic $δ$-TaN phase emerging for higher N contents. Phase composition remained unchanged before and after the 500C tests. However, after the high temperature tests, TEM analysis showed the presence of an oxide surface layer, with a thickness that decreased (from 42 to 15 nm) with N content, due to residual oxygen diffusion, which replaces nitrogen to form amorphous SiOx. Beneath the oxide-rich surface layer, coatings exhibited a stable nanocrystalline columnar microstructure. Hardness and fracture toughness increased with N content, initially due to the formation of an amorphous Si-N tissue at grain boundaries, and for even higher N contents, due to the appearance of the hard cubic $δ$-TaN phase. Hardness at 500C decreased only by 15%, while fracture toughness followed the opposite trend, due to increased plasticity with temperature. The optimum composition turned out to be Ta55Si10N35, which retained a hardness of 30 GPa at 500C, being also the toughest. These observations make this system very interesting for high temperature applications.

description: The effect of Alfvén waves on the thermal instability of the Interstellar Medium (ISM) is investigated both analytically and numerically. A stability analysis of a finite amplitude circularly polarized Alfvén wave propagating parallel to an ambient magnetic field in a thermally unstable gas at thermal equilibrium is performed, leading to a dispersion relation which depends on 3 parameters, namely the square ratio of the sonic and Alfvén velocities ($β$), the wave amplitude and the ratio between the wave temporal period and the cooling time. Depending on the values of these 3 parameters, the Alfvén waves can stabilize the large-scale perturbations, destabilize those whose wavelength is a few times the Alfvén wavelength $λ_{AW}$ or leave the growth rate of the short scales unchanged. In order to investigate the non-linear regime, two different numerical experiments are performed in a slab geometry. (TBC)

An important question in dynamical systems is to know when a function g:M -> R is a coboundary for the flow generated by X, i.e. when there exists a function f: M->R such that Xf=g. In this article we investigate this question for nilflows on nilmanifolds. We show that there exists countably many independent Schwartz distributions D_n such that any sufficiently smooth function g is a coboundary iff it belongs to the kernel of all the distributions D_n.

We show that the specific dependence on doping and on photon polarizations of these peaks is only compatible with charge collective excitations at finite wavelength.

description: We predict the mass fraction of oxygen lost from galaxies in a cosmological simulation as a function of stellar mass and environment at the present day. The distribution with stellar mass is bimodal, separating star-forming and quenched galaxies. The metallicity of gas and stars is self-consistently calculated using a chemical evolution model that includes supernovae type II and Ia, hypernovae, and asymptotic giant branch stars. The mass of oxygen lost from each galaxy is calculated by comparing the existing oxygen in gas and stars in the galaxy to the oxygen that should have been produced by the present-day population of stars. More massive galaxies are able to retain a greater fraction of their metals ($\sim 100$ per cent) than low-mass galaxies ($\sim 40 - 70$ per cent). As in the star formation main sequence, star-forming galaxies follow a tight relationship also in terms of oxygen mass lost -- a metal flow main sequence, ZFMS -- whereas massive quenched galaxies tend to have lost a greater fraction of oxygen (up to 20 per cent), due to AGN-driven winds. The amount of oxygen lost by satellite galaxies depends on the details of their interaction history, and those in richer groups tend to have lost a greater fraction of their oxygen. Observational estimates of metal retention in galaxies will provide a strong constraint on models of galaxy evolution.

description: Agricultural production almost needs to double in the 21st century, putting tremendous pressure on agricultural resources. Most food production increases must come from more agricultural intensification in the South. This advances the need for a new green revolution: higher productivity and at the same time less pressure on the environment. Agrobiotechnology can contribute to this double green revolution. Biotechnology innovations are often scale neutral and are therefore suitable for small farmers. Moreover, genetic modification offers especially advantages for crops domesticated since a very long time and which are therefore quite different from their wild relatives. However, agrobiotechnology also engenders risks and dangers, outlined in the paper. Multinational companies show little interest in small developing countries because the market is small and intellectual property rights protection is not effective. Not surprisingly, those are also the countries where food insecurity problems are most acute. In many developing countries the capacity to conduct own biotechnology research and development is lacking as well as the legal framework for biosafety testing, patent enforcement and release of transgenic crops. This is illustrated by a case study on transgenic plantain bananas, developed by the Catholic University of Leuven, Belgium. Therefore, the paper argues that legal and research capacity building are the main priorities. These can be achieved through public-private and North-South partnerships.

description: The literature on the evolution of farming systems in West Africa shows a large diversity of general theories on rural development. The purpose of this study is to revisit the theses of Malthus and Boserup and empirically test them on a case study of Northern Cote d'Ivoire. We have at our disposal a database spread over three agricultural seasons (1995-1998) and three villages. These villages differ strongly regarding their population density and historical genesis. The comparison between these villages permitted to track down their stage in the evolution of farming systems and to identify population pressure as a key factor of the evolution of farming systems and to identify population pressure as a key factor of the evolution process of farms. Our empirical analysis shows that Boserupian and Malthusian processes coexist, rather than contrast. Labor is the key factor for escaping Malthusian mechanisms and induces boserupian innovations that are crucial to the evolution trajectory of farms.

description: We provide the analytic predictions for the flavor non-singlet scalar correlator, which will enable determination of the scalar meson mass from the lattice scalar correlator. We consider simulations with 2+1 staggered sea quarks and staggered or chiral valence quarks. At small u/d masses the correlator is dominated by the bubble contribution, which is the intermediate state with two pseudoscalar mesons. We determine the bubble contribution within Staggered and Mixed Chiral Perturbation Theory. Its effective mass is smaller than the mass M_pi+M_eta, which is the lightest intermediate state in proper 2+1 QCD. The unphysical effective mass is a consequence of the taste breaking that makes possible the intermediate state with mass 2*M_pi. We find that the scalar correlator can be negative in the simulations with mixed quark actions if the sea and valence quark masses are tuned by matching the pion masses M_{val,val}=M_{pi_5}.

description: EK Dra (HD 129333) is a young, active, nearby star that is orbited by a low mass companion. By combining new speckle observations with old and new radial velocity measurements we find that the orbit is highly eccentric with e=0.82\pm0.03, and we derive the true masses of both components. The masses are $0.9\pm0.1 {\rm M}_\odot$ and $0.5\pm0.1 {\rm M}_\odot$, for the primary and secondary, respectively. From high resolution spectra we derive a new $T_{\rm eff}$ of $5700\pm70$ K, and a $\log g$ of $4.37\pm0.10$, which is different to previous estimates. However, the new spectroscopic distance differs by only 5.8% to the distance derived by parallax measurement of the Hipparcos satellite and thus the stellar parameters are presumably more realistic than older determinations. We derive a somewhat higher value for the metallicity of $[Fe/H]=-0.16\pm0.07$. EK Dra turns out to be one of the few nearby young stars which will evolve similar to the sun. The precise radial velocity measurements taken in the course of this program also allows us to shed more light on to the activity of this star. In 2001 and 2002 we find a periodic signal of the radial velocity variations with a period of $2.767\pm0.005$ days which we interpret as the rotation period. This signal vanishes in 2003. However the signal can be recovered if only the spectra in which the photospheric lines are asymmetric are used. On the other hand, we do not find a close correlation between the asymmetry of photospheric lines and the radial velocity.

description: This article discusses how computer technology was implemented within the US federal government in the 1960s and 1970s. Drawing on sources from the Bureau of the Budget (BOB), later renamed the Office of Management and Budget (OMB), the article demonstrates that the Johnson administration centralised the management of Automatic Data Processing (ADP) and also set technical standards. To characterise this process, the article proposes to use the expression “early phase of digitalisation”. At the time, a debate arose about how the processing of personal data would affect individual rights. Several studies analysed the functioning of technology with regard to computer privacy and suggested general guidelines. In addition, Congress passed data privacy legislation. Regardless of the legal debate, computerisation continued under the Nixon administration. The article argues that digitalisation shaped the privacy debate at the time.
On the rigidity of a hard sphere glass near random close packing

description: We study theoretically and numerically the microscopic cause of the mechanical stability of hard sphere glasses near their maximum packing. We show that, after coarse-graining over time, the hard sphere interaction can be described by an effective potential which is exactly logarithmic at the random close packing $ϕ_c$. This allows to define normal modes, and to apply recent results valid for elastic networks: mechanical stability is a non-local property of the packing geometry, and is characterized by some length scale $l^*$ which diverges at $ϕ_c$ [1, 2]. We compute the scaling of the bulk and shear moduli near $ϕ_c$, and speculate on the possible implications of these results for the glass transition.

description: Let A be a basic finite dimensional and connected algebra over an algebraically closed field k with zero characteristic. If the ordinary quiver of A has no double bypasses, we show that A admits a Galois covering which satisfies a universal property with respect to the Galois coverings of A. This universal property is similar to the one of the universal cover of a connected topological space.
description: This text (21 pages) gives detailed proofs of the results announced in a previous note of the author (The fundamental group of a triangular algebra without double bypasses) and extends the study of this previous note to the Galois coverings of an algebra

description: We have studied the behavior of the superconducting critical temperature Tc in $Nb/Co_{60}Fe_{40}$, Nb/Ni, and $Nb/Cu_{40}Ni_{60}$ bilayers as a function of the thickness of each ferromagnetic metal layer. The Tc s of three sets of bilayers exhibit non-monotonic behavior as a function of each ferromagnetic metal thickness. Employing the quantitative analysis based on Usadel formalism of the effect of the exchange energy, we observed that the Tc behavior of $Nb/Co_{60}Fe_{40}$ bilayers is in good agreement with the theoretical values over the entire range of the data. On the other hand, the Tc s of Nb/Ni and $Nb/Cu_{40}Ni_{60}$ bilayers show a higher value in the small thickness regime than the theoretical prediction obtained from the calculation, which matches the dip position and the saturation value of Tc in the large thickness limit. This discrepancy is probably due to the weakened magnetic properties of Ni and $Cu_{40}Ni_{60}$ when they are thin. We discuss the values of our fitting parameters and its implication on the validity of the current Usadel formalism of the effect of the exchange energy.

title: Targeting benefits and interactions in multisensory processing : a novel modelling framework for exploring the redundant signal effect
Creators: name: Innes, Bobby Richard
Publisher: name: University of St Andrews
Year: 2019

description: An overarching goal of multisensory research is to understand the rules by which multiple sensory signals are combined to produce behavioural benefits. One example of a multisensory benefit is that response times (RTs) to multisensory signals are faster than RTs to either component unisensory signal (the redundant signal effect). In contrast to other areas of multisensory research, a common explanatory model framework (and thus the basic combination rule) has yet to emerge for multisensory RT benefits. One key reason for this lack of progress would seem to be that additional processing interactions are infrequently quantified, and are rarely incorporated into a formal model of RTs. In this thesis, I assess the ability of a previously-neglected model class – so called race models – to account for both benefits and interactions. To do so, I develop and apply a comparative approach to RT analysis. This approach tests different experimental factors which attempt target sources of benefits and interactions. The effect of these manipulations is compared across 3 key analytical steps. First, the size of the multisensory benefit (i.e. the redundant signal effect) is computed, and compared to the basic prediction of the race model combination rule. Second, indicators of processing interactions beyond the basic combination rule are quantified. Third, a formal race model is applied to explain benefits and processing interactions. By consistently applying this comparative approach, I demonstrate that the race model framework offers a simple yet powerful account of multisensory benefits across participants. This suggests a basic combination rule for multisensory RT benefits. In addition, a new interpretation of interactions emerges by applying a race model framework, which highlights an important role of context. This approach suggests a common foundation for future studies of multisensory RTs, which can implement the same analytical steps within a wide range of experimental contexts.

Nontrapping arrest of Langmuir wave damping near the threshold amplitude

description: Evolution of a Langmuir wave is studied numerically for finite amplitudes slightly above the threshold which separates damping from nondamping cases. Arrest of linear damping is found to be a second-order effect due to ballistic evolution of perturbations, resonant power transfer between field and particles, and organization of phase space into a positive slope for the average distribution function $f_{av}$ around the resonant wave phase speed $v_ϕ$. Near the threshold trapping in the wave potential does not arrest damping or saturate the subsequent growth phase.
