description: The stock market continues to pressure all corporations to generate profitable growth in both the short and long term. Long-term success is dependent on a firm's capability to develop and implement strategy. The successful strategy combines resources and competencies from across the organization to fully exploit growth potential by allocating those resources to new business opportunities. Resource allocation is a challenging process, concerning management of scarce resources. Resources include money, equipment, raw goods, labour, and management time. The objective of this research is to describe the key components of the organizational context that define the resource allocation process in Canadian subsidiaries of large oil and gas corporations. More specifically, the thesis will focus on parameters such as subsidiary type, corporate context, procedural justice and coordination/control (transaction) costs, as indicators that provide a basis to distinguish among various types of resource allocation systems. Additionally, the study will provide details on the informal process of project substitution. Project substitution is the process of substituting projects in place of cancelled or delayed projects that were approved during the annual capital budget cycle. The resources that one division gets, others cannot. This balance is often the discord between funding induced projects and autonomous projects. The key findings in this study result from case studies of seven oil and gas subsidiaries. The case studies suggest specific interrelationships among subsidiary types, structural context, transaction costs and corporate context. Canadian subsidiaries from companies that have continued to operate and grow their subsidiaries in Canada tend to be strategic leaders associated with low transaction costs and high procedural justice.

description: We define a numerical method that provides a non-parametric estimation of the kernel shape in symmetric multivariate Hawkes processes. This method relies on second order statistical properties of Hawkes processes that relate the covariance matrix of the process to the kernel matrix. The square root of the correlation function is computed using a minimal phase recovering method. We illustrate our method on some examples and provide an empirical study of the estimation errors. Within this framework, we analyze high frequency financial price data modeled as 1D or 2D Hawkes processes. We find slowly decaying (power-law) kernel shapes suggesting a long memory nature of self-excitation phenomena at the microstructure level of price dynamics.

description: With Monte Carlo methods, we investigate the relaxation dynamics of a domain wall in the two-dimensional random-field Ising model with a driving field. The short-time dynamic behavior at the depinning transition is carefully examined, and the roughening process of the domain wall is observed. Based on the short-time dynamic scaling form, we accurately determine the transition field, static and dynamic exponents, and local and global roughness exponents. In contrast to the usual assumption, the results indicate that the domain interface does not belong to the universality class of the Edwards-Wilkinson equation. In particular, due to the dynamic effect of overhangs, the domain interface exhibits intrinsic anomalous scaling and spatial multiscaling behaviors, compatible with the experiments

description: The evaporation of liquid droplets often results in a ring-like deposition pattern of particles, presenting challenges for applications requiring highly uniform patterns. Despite extensive efforts to suppress the coffee ring effect, achieving a uniform particle distribution remains a great challenge due to the complex and non-equilibrium nature of the evaporation process. In this work, we introduce and demonstrate a one-step drying method for binary droplets (water and 2-methoxyethanol) that produces uniform deposition of nano- and micro-particles. By adjusting the initial water volume fraction, we effectively control the interplay between capillary and Marangoni flows, resulting in deposition patterns that vary from coffee ring to uniform and to volcano-like. Through both theoretical and experimental analyses, we determine the conditions necessary for achieving such high uniformity. This approach requires no special substrate treatment, particle modification, or controlled environments, and works for various particles, including silica and polystyrene. Our method provides a robust solution for fabricating uniform patterns that are crucial for many practical applications, ranging from printing to microelectronics to bio-pharmacy.

description: Multiple $Λ$CDM cosmology is studied in a way that is formally a classical analog of the Casimir effect. Such cosmology corresponds to a time-dependent dark fluid model or, alternatively, to its scalar field presentation, and it motivated by the string landscape picture. The future evolution of the several dark energy models constructed within the scheme is carefully investigated. It turns out to be almost always possible to choose the parameters in the models so that they match the most recent and accurate astronomical values. To this end, several universes are presented which mimick (multiple) $Λ$CDM cosmology but exhibit Little Rip, asymptotically de Sitter, or Type I, II, III, and IV finite-time singularity behavior in the far future, with disintegration of all bound objects in the cases of Big Rip, Little Rip and Pseudo-Rip cosmologies.

description: Lung cancer is among the most common cancers in the United States, in terms of incidence and mortality. In 2009, it is estimated that more than 150,000 deaths will result from lung cancer alone. Genetic information is an extremely valuable data source in characterizing the personal nature of cancer. Over the past several years, investigators have conducted numerous association studies where intensive genetic data is collected on relatively few patients compared to the numbers of gene predictors, with one scientific goal being to identify genetic features associated with cancer recurrence or survival. In this note, we propose high-dimensional survival analysis through a new application of boosting, a powerful tool in machine learning. Our approach is based on an accelerated lifetime model and minimizing the sum of pairwise differences in residuals. We apply our method to a recent microarray study of lung adenocarcinoma and find that our ensemble is composed of 19 genes, while a proportional hazards (PH) ensemble is composed of nine genes, a proper subset of the 19-gene panel. In one of our simulation scenarios, we demonstrate that PH boosting in a misspecified model tends to underfit and ignore moderately-sized covariate effects, on average. Diagnostic analyses suggest that the PH assumption is not satisfied in the microarray data and may explain, in part, the discrepancy in the sets of active coefficients. Our simulation studies and comparative data analyses demonstrate how statistical learning by PH models alone is insufficient.

description: Interference and coincidence detection of two photons emitted by two remote ions can lead to an entangled state which is a critical resource for scalable quantum information processing. Currently, the success probabilities of experimental realizations of this protocol are mainly limited by low coupling efficiency of a photon emitted by an ion into a single mode fiber. Here, we consider two strategies to enhance the collection probability of a photon emitted from a trapped Yb ion, using analytic methods that can be easily applied to other types of ion or neutral atoms. Our analysis shows that we can achieve fiber coupling efficiency of over 30% with an optical cavity made of a flat fiber tip and a spherical mirror. We also investigate ways to increase the fiber coupling efficiency using high numerical aperture optics, and show that collection probability of over 15% is possible with proper control of aberration.

description: Noise is an unavoidable part of most measurements which can hinder a correct interpretation of the data. Uncertainties propagate in the data analysis and can lead to biased results even in basic descriptive statistics such as the central moments and cumulants. Expressions of noise-unbiased estimates of central moments and cumulants up to the fourth order are presented under the assumption of independent Gaussian uncertainties, for weighted and unweighted statistics. These results are expected to be relevant for applications of the skewness and kurtosis estimators such as outlier detections, normality tests and in automated classification procedures. The comparison of estimators corrected and not corrected for noise biases is illustrated with simulations as a function of signal-to-noise ratio, employing different sample sizes and weighting schemes.

Real-time integration of a tactical-grade IMU and GPS for high-accuracy positioning and navigation

description: Bibliography: p. 197-208
description: The integration of the Global Positioning System (GPS) and Inertial Navigation Systems (INSs) is often used to provide accurate positioning and navigation information. For applications requiring the highest accuracy, the quality of the inertial sensors required is usually assumed to be very high. This dissertation investigates the integration of GPS with a tactical-grade Inertial Measurement Unit (IMU) for centimetre-level navigation in real-time. Different GPS/INS integration strategies are investigated to assess their relative performance in terms of position and velocity accuracy during partial and complete data outages, carrier phase ambiguity resolution after such data outages, and the overall statistical reliability of the system. In terms of statistical reliability, the traditional equations used in dynamic systems are redeveloped in light of some practical considerations, including centralized and decentralized filter architectures, and sequential versus simultaneous measurement updating. Results show that the integrated solution outperforms the GPS-only approach in all areas. The difference between loose and tight integration strategies was most significant for ambiguity resolution and system reliability. The integrated solution is capable of providing decimetre-level accuracy or better for durations of about five or ten seconds when a complete or partial GPS outage is simulated. This level of accuracy, extended over longer time intervals, is shown to reduce the time required to resolve the 11 ambiguities by an average of about 50% or more for data outages as long as 30 seconds when using a tight integration strategy. More importantly, the reliability of the ambiguity resolution process is improved with the integrated system. Statistical reliability parameters are also dramatically better when using the integrated system with the ability of detecting a single-cycle cycle slip being better and more consistent, relative to GPS-only. The effect of undetected blunders on the final system is also significantly reduced. Two real-time tests are analyzed and results show that directly resolving the 11 ambiguities is still unreliable in suburban environments, even with the integrated system. However, using the widelane phase observable, sub-decimetre navigation is demonstrated in suburban and pseudo-urban environments, despite the relatively adverse operational conditions encountered.

description: Neutron-proton (np-) pairing is expected to play an important role in the N Z nuclei. In general, it can have isovector and isoscalar character. The existence of isovector np-pairing is well established. On the contrary, it is still debated whether there is an isoscalar np-pairing. The review of the situation with these two types of pairing with special emphasis on the isoscalar one is presented. It is concluded that there are no substantial evidences for the existence of isoscalar np-pairing.

description: Many machine learning algorithms minimize a regularized risk, and stochastic optimization is widely used for this task. When working with massive data, it is desirable to perform stochastic optimization in parallel. Unfortunately, many existing stochastic optimization algorithms cannot be parallelized efficiently. In this paper we show that one can rewrite the regularized risk minimization problem as an equivalent saddle-point problem, and propose an efficient distributed stochastic optimization (DSO) algorithm. We prove the algorithm's rate of convergence; remarkably, our analysis shows that the algorithm scales almost linearly with the number of processors. We also verify with empirical evaluations that the proposed algorithm is competitive with other parallel, general purpose stochastic and batch optimization algorithms for regularized risk minimization.

description: Connectivity is a homotopy invariant property of a separable C*-algebra A which has three important consequences: absence of nontrivial projections, quasidiagonality and realization of the Kasparov group KK(A,B) as homotopy classes of asymptotic morphisms from A to the stabilization of B if A is nuclear. Here we give a new characterization of connectivity for separable exact C*-algebras and use this characterization to show that the class of discrete countable amenable groups whose augmentation ideals are connective is closed under generalized wreath products. In a related circle of ideas, we give a result on quasidiagonality of reduced crossed-product C*-algebras associated to noncommutative Bernoulli actions.

In this paper we characterize the Hilbert's metric isometries on the interiors of cones in JBW-algebras, and the Thompson's metric isometries on the interiors of cones in JB-algebras. These characterizations generalize work by Bosché on the Hilbert and Thompson isometries on symmetric cones, and work by Hatori and Molnár on the Thompson isometries on the cone of positive self-adjoint elements in a unital $C^*$-algebra. To obtain the results we develop a variety of new geometric and Jordan algebraic techniques.

description: Every unitary involutive solution of the quantum Yang-Baxter equation ("R-matrix") defines an extremal character and a representation of the infinite symmetric group $S_\infty$. We give a complete classification of all such Yang-Baxter characters and determine which extremal characters of $S_\infty$ are of Yang-Baxter form. Calling two involutive R-matrices equivalent if they have the same character and the same dimension, we show that equivalence classes are classified by pairs of Young diagrams, and construct an explicit normal form R-matrix for each class. Using operator-algebraic techniques (subfactors), we prove that two R-matrices are equivalent if and only if they have similar partial traces. Furthermore, we describe the algebraic structure of the equivalence classes of all involutive R-matrices, and discuss several classes of examples. These include unitary Yang-Baxter representations of the Temperley-Lieb algebra at loop parameter $δ=2$, which can be completely classified in terms of their rank and dimension.

description: The purpose of the present study was to explore the experience of teachers and the impact of the curriculum on their relationships with students. Four teachers were interviewed over the course of five months and their experiences were interpreted and discussed within a hermeneutic framework. What emerged from those discussions was a more informed understanding of the barriers that impede good learning, how these barriers can be negotiated and why they must be explored in order to facilitate learning. A postmodern re-interpretation of the discussions revealed how the modernist conception of learning interferes with our students' ability to belong not only in the school, but also on the planet.

description: We present an analytic description of numerical results for the Landau-gauge SU(2) gluon propagator D(p^2), obtained from lattice simulations (in the scaling region) for the largest lattice sizes to date, in d = 2, 3 and 4 space-time dimensions. Fits to the gluon data in 3d and in 4d show very good agreement with the tree-level prediction of the Refined Gribov-Zwanziger (RGZ) framework, supporting a massive behavior for D(p^2) in the infrared limit. In particular, we investigate the propagator's pole structure and provide estimates of the dynamical mass scales that can be associated with dimension-two condensates in the theory. In the 2d case, fitting the data requires a non-integer power of the momentum p in the numerator of the expression for D(p^2). In this case, an infinite-volume-limit extrapolation gives D(0) = 0. Our analysis suggests that this result is related to a particular symmetry in the complex-pole structure of the propagator and not to purely imaginary poles, as would be expected in the original Gribov-Zwanziger scenario.

description: This paper introduces the combinatorial Boolean model (CBM), which is defined as the class of linear combinations of conjunctions of Boolean attributes. This paper addresses the issue of learning CBM from labeled data. CBM is of high knowledge interpretability but naïve learning of it requires exponentially large computation time with respect to data dimension and sample size. To overcome this computational difficulty, we propose an algorithm GRAB (GRAfting for Boolean datasets), which efficiently learns CBM within the $L_1$-regularized loss minimization framework. The key idea of GRAB is to reduce the loss minimization problem to the weighted frequent itemset mining, in which frequent patterns are efficiently computable. We employ benchmark datasets to empirically demonstrate that GRAB is effective in terms of computational efficiency, prediction accuracy and knowledge discovery.
Low complexity indoor wireless data links using chirp spread spectrum
Creators: name: Pinkney, John
Publisher: name: University of Calgary
Year: 2003

description: Bibliography: p. 236-243.
description: This dissertation proposes the use of Chirp Spread Spectrum ( CSS) modulation for the transfer of high-speed (> 10 megabits per second) data in the indoor wireless environment. CSS utilizes the properties of chirp signals to combat the effects of multipath fading. The major advantage CSS has over other spectrum spreading techniques is its analog-only implementation. Two main methods for deploying CSS are described: Binary Orthogonal Keying (BOK) , in which chirp signals with different characteristics represent different data symbols, and Direct Modulation (DM) , where data is modulated using a conventional non-coherent modulation scheme, and then has its bandwidth spread by the chirp signal. Performance equations for the Gaussian channel are derived for both systems. Several other key system design parameters are identified and explored, including chirp windowing, occupied bandwidth, and quasi-RAKE filter configuration. Computer simulations and prototype measurements show close agreement with the developed theory. Raw bit error rates less than 10-5 at 20 megabits per second are achieved, with a bandwidth of 200 MHz in non line of sight wireless channels over 10 m with less than 2 milli-Watts of transmit power. Techniques for designing SAW chirp filters with both linear and nonlinear time-frequency responses are described, and measurements of a prototype SAW device are presented. Novel methods for enhancing the throughput of a binary CSS system are presented which increase the number of bits per symbol of the modulation CSS signal. Computer simulations show that data rates of 50 megabits per second are achievable for a single channel system using this method.

description: We address shock waves generated upon the interaction of tilted plane waves with negative refractive index defect in defocusing media with linear gain and two-photon absorption. We found that in contrast to conservative media where one-dimensional dispersive shock waves usually exist only as nonstationary objects expanding away from defect or generating beam, the competition between gain and two-photon absorption in dissipative medium results in the formation of localized stationary dispersive shock waves, whose transverse extent may considerably exceed that of the refractive index defect. One-dimensional dispersive shock waves are stable if the defect strength does not exceed certain critical value.

description: Many methods have been developed to secure the network infrastructure and communication over the Internet. Intrusion detection is a relatively new addition to such techniques. Intrusion detection systems (IDS) are used to find out if someone has intrusion into or is trying to get it the network. One big problem is amount of Intrusion which is increasing day by day. We need to know about network attack information using IDS, then analysing the effect. Due to the nature of IDSs which are solely signature based, every new intrusion cannot be detected; so it is important to introduce artificial intelligence (AI) methods / techniques in IDS. Introduction of AI necessitates the importance of normalization in intrusions. This work is focused on classification of AI based IDS techniques which will help better design intrusion detection systems in the future. We have also proposed a support vector machine for IDS to detect Smurf attack with much reliable accuracy.

description: In a recent work [Potter and Lee, Phys. Rev. Lett. 105, 227003 (2010)], it was demonstrated by means of numerical diagonalization that the Majorana end states can be localized at opposite ends of a sample of an ideal spinless p-wave superconductor with the strip geometry beyond the strict one-dimensional limit. Here we reexamine this issue, and study the topological quantum phase transition in the same system. We give the phase diagrams of the presence of Majorana end modes by using of $Z_{2}$ topological index. It is found that the topological property of a strip geometry will change in an oscillatory way with respect of the sample width.

description: An upper bound on Lyapunov exponent of a thermal many body quantum system has been conjectured recently. In this work, we attempt to achieve a physical understanding of what prevents a system from violating this bound. To this end, we propose - super-maximal chaos leads to instability. Our proposal is supported by findings in a SYK lattice model, with a tuneable parameter, which the Lyapunov spectrum depends upon. In the stable regime of this parameter, along with incoherent metallic phase, the system exhibits another novel phase, where transport is controlled neither by quasi-particles nor by diffusion. At the phase transition, diffusion coefficient, butterfly velocity and Thouless time diverges.

description: We explore the suggestions by Uzdensky (2007) and Cassak et al. (2008) that coronal loops heated by magnetic reconnection should self-organize to a state of marginal collisionality. We discuss their model of coronal loop dynamics with a one-dimensional hydrodynamic calculation. We assume that many current sheets are present, with a distribution of thicknesses, but that only current sheets thinner than the ion skin depth can rapidly reconnect. This assumption naturally causes a density dependent heating rate which is actively regulated by the plasma. We report 9 numerical simulation results of coronal loop hydrodynamics in which the absolute values of the heating rates are different but their density dependences are the same. We find two regimes of behavior, depending on the amplitude of the heating rate. In the case that the amplitude of heating is below a threshold value, the loop is in stable equilibrium. Typically the upper and less dense part of coronal loop is collisionlessly heated and conductively cooled. When the amplitude of heating is above the threshold, the conductive flux to the lower atmosphere required to balance collisionless heating drives an evaporative flow which quenches fast reconnection, ultimately cooling and draining the loop until the cycle begins again. The key elements of this cycle are gravity and the density dependence of the heating function. Some additional factors are present, including pressure driven flows from the loop top, which carry a large enthalpy flux and play an important role in reducing the density. We find that on average the density of the system is close to the marginally collisionless value.

description: We investigate toric varieties defined by arrangements of hyperplanes and call them strongly symmetric. The smoothness of such a toric variety translates to the fact that the arrangement is crystallographic. As a result, we obtain a complete classification of this class of toric varieties. Further, we show that these varieties are projective and describe associated toric arrangements in these varieties.

description: Three-dimensional (3-D) dynamical models of hot Jupiter atmospheres predict very strong wind speeds. For tidally locked hot Jupiters, winds at high altitude in the planet's atmosphere advect heat from the day side to the cooler night side of the planet. Net wind speeds on the order of 1-10 km/s directed towards the night side of the planet are predicted at mbar pressures, which is the approximate pressure level probed by transmission spectroscopy. These winds should result in an observed blue shift of spectral lines in transmission on the order of the wind speed. Indeed, Snellen et al. (2010) recently observed a 2 +/- 1 km/s blue shift of CO transmission features for HD 209458b, which has been interpreted as a detection of the day-to-night winds that have been predicted by 3-D atmospheric dynamics modeling. Here we present the results of a coupled 3-D atmospheric dynamics and transmission spectrum model, which predicts the Doppler-shifted spectrum of a hot Jupiter during transit resulting from winds in the planet's atmosphere. We explore four different models for the hot Jupiter atmosphere using different prescriptions for atmospheric drag via interaction with planetary magnetic fields. We find that models with no magnetic drag produce net Doppler blue shifts in the transmission spectrum of ~2 km/s and that lower Doppler shifts of ~1 km/s are found for the higher drag cases, results consistent with -- but not yet strongly constrained by -- the Snellen et al. (2010) measurement. We additionally explore the possibility of recovering the average terminator wind speed as a function of altitude by measuring Doppler shifts of individual spectral lines and spatially resolving wind speeds across the leading and trailing terminators during ingress and egress.

Modeling Emotion across Languages, Label Formats, and Linguistic Levels

description: Language-based emotion analysis finds itself in a paradoxical situation. In the past decades, a plethora of datasets have been created, covering diverse aspects of natural language and affective states. However, the considerable volume of resulting gold data is scattered across many design decisions in dataset creation, acting as sources of heterogeneity (e.g., different natural languages, linguistic units of different sizes such as words, sentences, and texts, the choice for a particular set of emotion variables, and the selection of a particular viewpoint such as the reader or the writer perspective on emotion). On the one hand, this proliferating heterogeneity makes it difficult to re-use existing datasets and software tools or to compare experimental results following different design decisions. On the other hand, this heterogeneity is empirically adequate and valuable from an application perspective. Thus, the solution to the heterogeneity problem cannot be to simply reduce the number of possible design choices through community-wide consensus. Rather, what is needed is a delicate balance between fostering the diversity of emotion data and developing new methods to tackle the resulting comparability issues. This interplay between diversity and comparability of emotion data is the focus area of this thesis and the seven studies compiled within it. The larger vision behind this dissertation is to arrive at a research landscape where diversity and comparability no longer act as antagonists and instead every new sample of annotated data, regardless of the specifics of its annotation design, benefits the endeavor of emotion analysis as a whole. While NLP is still far from achieving this goal, the presented research results, culminating in the establishment of an “emotion interlingua” in the final study, constitute a significant step in this direction.
A study of the protective properties of oxide films formed at reactive Al-Cu and Al-Be alloys

description: Two Al alloys of interest to the aerospace industry were studied during this research. AA22 l 9 is an Al/Cu alloy containing about 6%-wt Cu, forming Cu-rich particles in a Cu­poor Al-matrix. AlBeMet162 is an Al/Be alloy consisting of ca. 38%-wt Al and 62%-wt Be, forming intermeshed networks of Al and Be. Both alloys do not respond to standard anodization techniques in sulfuric or chromic acid, yielding pitted surfaces and friable anodic coatings. Corrosion protection can be achieved on AA22 l 9 but a significant part of its fatigue strength will be sacrificed as a result of these anodization processes, while no corrosion protection results from the anodization of AlBeMetl 62. Thus, the main goals of this work were preventing the dissolution of the more reactive alloy constituents and electrochemical formation of a passivating surface coating. Cyclic Voltammetry methods (CV) were used as a means of creating barrier and porous oxide layers on AA22 l 9, AlBeMetl 62 and the individual phases making up these alloys. The CV data and measurements of Electrochemical Impedance Spectroscopy (EIS) were used to determine the thickness and dissolution activity of the barrier oxide layers formed. Changes in the barrier oxide thickness during EIS and CV experiments in neutral borate and phosphate buffer as well as H2SO4 and H3PO4 solutions provided a means for predicting whether a stable barrier or porous oxide film would likely be formed in a given electrolyte. This approach was shown to be usable even in the presence of an overlying porous oxide film. The CV data were also examined for an indication of the oxide growth mechanism, with a particular focus on the High Field and Point Defect models, indicating that the High Field Model more closely fits the data acquired. EIS data collected in 5%-wt NaCl solution were shown to give a good indication of the corrosion protection granted by anodic coatings formed on Al alloys and thus to be a suitable method for accelerated corrosion testing. DC anodization at only 2.5 V in neutral buffers and acidic solutions as well as and AC/DC anodization at voltages exceeding 100 V in alkaline silicate solutions were also studied and shown to successfully form anodic oxides without dissolving the reactive constituents of AA22 l 9. Accelerated corrosion testing and microscopic examination of corroded samples suggested that neither of these coatings supplied acceptable corrosion protection, but the silicate coatings appeared very promising, and further optimization of this approach is recommended.

description: Systematic investigation of the accuracy of the description of the energies of deformed one-quasiparticle states has been performed in covariant density functional theory in actinide and rare-earth mass regions. The sources of the discrepancies between theory and experiment are analyzed. Although some improvements in the description of ground state configurations and one-quasiparticle spectra can be achieved by better parametrization of the relativistic mean field Lagrangian, the analysis suggests that spectroscopic quality of their description can be achieved only in theoretical framework which takes into account particle-vibration coupling.

description: We apply the Hubbard model, non-equilibrium Green's function (NEGF) theory, exact diagonalization (ED) and the hierarchical equations of motion (HEOM) method to investigate abundant magnetic phase transitions in the 1D interacting quantum dots arrays (QDA) sandwiched by non-interaction leads. The spin polarization phase transitions are firstly studied with a mean-field approximation. The many-body calculation of the ED method is then used to verify such transitions. We find with the weak device-leading couplings, the anti-ferromagnetic (AF) state only exists in the uniform odd-numbered QDA or the staggered-hopping QDA systems. With increasing the coupling strength or the bias potentials, there exists the magnetism-to non-magnetism phase transition. With the spin-resolved HEOM method we also investigate the detailed dynamic phase transition process of these lead-QDA-lead systems.

description: In order to find the most extreme dust-hidden high-redshift galaxies, we select 196 extremely red objects in the Ks and IRAC bands (KIEROs, [Ks-4.5um](AB)>1.6) in the 0.06 deg^2 GOODS-N region. This selection avoids the Balmer breaks of galactic spectra at z<4 and picks up red galaxies with strong dust extinction. The photometric redshifts of KIEROs are between 1.5 and 5, with ~70% at z~2-4. KIEROs are very massive, with M*~10^10-10^12 Msun. They are optically faint and usually cannot be picked out by the Lyman break selection. On the other hand, the KIERO selection includes approximately half of the known millimeter and submillimeter galaxies in the GOODS-N. Stacking analyses in the radio, millimeter, and submillimeter all show that KIEROs are much more luminous than average 4.5um selected galaxies. Interestingly, the stacked fluxes for ACS-undetected KIEROs in these wavebands are 2.5-5 times larger than those for ACS-detected KIEROs. With the stacked radio fluxes and the local radio-FIR correlation, we derive mean infrared luminosities of 2-7x10^12 Lsun and mean star formation rates of 300-1200 Msun/yr for KIEROs with redshifts. We do not find evidence of a significant subpopulation of passive KIEROs. The large stellar masses and star formation rates imply that KIEROs are $z>2$ massive galaxies in rapid formation. Our results show that a large sample of dusty ultraluminous sources can be selected in this way and that a large fraction of high-redshift star formation is hidden by dust.
