description: A lot of Materials out there either in softcopy online or hardcopy over the shelve has proven difficult to understand due to high technicality in the style of writing. The are so much of mathematical formulas and terms that are difficult for upcoming scholars in this field of artificial intelligence to grasp. This has discouraged young scholar. The need to simplify what artificial intelligence really is, is necessary to encourage more people to see its beauty and benefit. Developing countries need more of this knowledge in order to invest and develop artificial intelligence related projects to encourage fast growing rate. This article is written in the simplest of terms for people to appreciate artificial intelligence. It is free of mathematical formulas which is one of the discouraging factors in the study of artificial intelligence. It is aimed at providing the basics building foundation for scholars intending to embark on artificial intelligence projects

Reservation arbitrated access for variable bit rate isochronous traffic transport over dual bus metropolitan area networks
Creators: name: Chan, Henry C. B.
Publisher: name: University of British Columbia
Year: 2009

description: TEEE 802.6 is an international standard for metropolitan area networks (MANs) based on a dual bus architecture. In addition to its deployment for interconnecting local area networks (LANs), 802.6 MANs can also be used as broadband multiplexers for integrating different types of traffic over broadband integrated services digital networks employing asynchronous transfer mode (ATM/BISDN) and as distributive switches to support wireless personal communication services. This thesis proposes a novel reservation arbitrated (RA) access protocol for transporting variable bit rate isochronous traffic (VBRIT) such as packet voice and video over dual bus MANs in general and IEEE 802.6 MANs in particular. RA access allows a variable bit rate isochronous source (VBRS) to capture and reserve isochronous channels on a bandwidth dn demand basis yielding substantial capacity improvements over pre-arbitrated (PA) access and providing a guaranteed transport service compared to queue-arbitrated (QA) access. To resolve possible access contention in the reservation process, a simple resolution mechanism is proposed where the upstream nodes yield to the downstream nodes during the confirmation stage. Nevertheless the contention problem can be completely eliminated under the typical coverage area of a MAN by setting the operation parameters properly. A rich family of RA access protocols can be found based on different methods of acquiring the incremental bandwidth. In particular, a new cyclic capturing mechanism is proposed to provide fair access service. The performance of RA access is analyzed extensively by analytical methods and computer simulations based on different VBRS models covering voice, video conference and motion video traffic. Three methods: uncontrolled bandwidth sharing, dynamic bandwidth partitioning and dynamic bandwidth sharing and the associated connection admission control (CAC) mechanisms are evaluated for multiplexing heterogeneous VBRIT. A movable boundary integration scheme is proposed to integrate PA, QA and RA traffic efficiently which gives significant capacity improvement over existing integration methods in the 802.6 standard. An important application of RA access is to facilitate the efficient transport of real time traffic over MAN-based personal communication networks and enterprise networks.

description: Using a well-focused soft X-ray synchrotron radiation beam, angle-resolved photoelectron spectroscopy was applied to a full-Heusler-type Co$_2$MnGe alloy to elucidate its bulk band structure. A large parabolic band at the Brillouin zone center and several bands that cross the Fermi level near the Brillouin zone boundary were identified in line with the results from first-principles calculations. These Fermi level crossings are ascribed to majority spin bands that are responsible for electron transport with extremely high spin polarization especially along the direction being perpendicular to the interface of magneto-resistive devices. The spectroscopy confirms there is no contribution of the minority spin bands to the Fermi surface, signifying half-metallicity for the alloy. Furthermore, two topological Weyl cones with band crossing points were identified around the $X$ point, yielding the conclusion that Co$_2$MnGe could exhibit topologically meaningful behavior such as large anomalous Hall and Nernst effects driven by the Berry flux in its half-metallic band structure.

description: We analyze a method of compressing a cloud of cold atoms by dynamic control of a far off resonance optical lattice. We show that by reducing the lattice spacing either continuously or in discrete steps while cooling the atoms with optical molasses large compression factors can be achieved. Particle motion in the time dependent lattice is studied numerically using a three dimensional semiclassical model. Two experimentally realistic models are analyzed. In the first we continuously vary the lattice beam angles to compress atoms initially in a Gaussian distributed cloud with standard deviation of $250 μ\rm m$ into a single site of a two-dimensional lattice of area $A\sim 35\times 35 λ^2$, with $λ$ the wavelength of the lattice beams. This results in an optical depth for an on-resonant probe beam $>80$ which is an increase by a factor of about 1800 compared to the uncompressed cloud. In the second approach we use a discrete set of lattice beam angles to decrease the spatial scale of the cloud by a factor of 500, and localize a few atoms to a single lattice site with an area $A\stackrel{

description: We establish the most general form of the discrete elasticity of a 2D triangular lattice embedded in three dimensions, taking into account up to next-nearest neighbour interactions. Besides crystalline system, this is relevant to biological physics (e.g., red blood cell cytoskeleton) and soft matter (e.g., percolating gels, etc.). In order to correctly impose the rotational invariance of the bulk terms, it turns out to be necessary to take into account explicitly the elasticity associated with the vertices located at the edges of the lattice. We find that some terms that were suspected in the litterature to violate rotational symmetry are in fact admissible

Tau leap methods for stiff stochastic chemical systems
Creators: name: Yang, Yushu
Publisher: name: Maryland Shared Open Access Repository
Year: 2011

description: Tau leap methods enable efficient simulation of stochastic chemical systems. We develop new tau leap methods that consider the following issues: stiffness, fluid limit, integer-valued states, nonnegative states, and correlations among species. We propose two tau leap methods taking into account a compromise among these issues. Both tau leap methods have the implicit Euler as their fluid limit, which is accomplished by the use of a split step: the first part computes the mean update implicitly, and the second part generates a random update explicitly with the mean computed in the first part.   The first tau leap method is designed to generate physically feasible population vectors yielding integer and nonnegative population states, and we refer to it as the Minkowski-Weyl tau (MW-tau) leap method. It incorporates the Minkowski-Weyl decomposition from polyhedral theory in generating nonnegative states, and three variants are proposed to reflect the idea of the method. The second method is devised to approximate the correlations among species, and it is called the tau leap method via local linear noise approximation (LLNA-tau). It utilizes the linear noise approximation (LNA) to obtain ODEs governing the evolution of the mean and the covariance for stochastic chemical systems. LLNA-tau applies LNA to approximate the mean and the covariance for reactions within one time step. The LNA is recalculated after each time step, and the population state is updated by Gaussian random variables with the approximated mean and covariance. Analysis of consistency, stability and fluid limit of the tau leap methods are also presented.   We illustrate MW-tau and LLNA-tau by some numerical examples, and compare them with existing tau leap methods. For most cases, the MW-tau and LLNA-tau methods perform favorably.

description: Physiologically-based pharmacokinetic (PBPK) modeling has reached considerable sophistication in its application in the pharmacological and environmental health areas. Yet, mature methodologies for making statistical inferences have not been routinely incorporated in these applications except in a few data-rich cases.  In this dissertation we look at two important applications of PBPK modeling for which we will study and conduct a rigorous statistical analysis.  Both frequentist and Bayesian statistical methods of analysis are explored. In the first application, we work with a previously developed PBPK model for the formation and disposition of DNA-protein cross-links formed by inhaled formaldehyde in the nasal lining of rats and rhesus monkeys and provide improved statistical inference on estimated model parameters. We purposefully choose this model because it is based on sparse time course data.  The second application considers a PBPK model developed for inhalation and metabolism of dichloromethane (DCM, methylene chloride).  In this application we work with time course data that exhibit serial correlation.

description: The propagation of high-frequency gravitational waves can be analyzed using the geometrical optics approximation. In the case of large but finite frequencies, the geometrical optics approximation is no longer accurate, and polarization-dependent corrections at first order in wavelength modify the propagation of gravitational waves via a spin-orbit coupling mechanism. We present a covariant derivation from first principles of effective ray equations describing the propagation of polarized gravitational waves, up to first-order terms in wavelength, on arbitrary spacetime backgrounds. The effective ray equations describe a gravitational spin Hall effect for gravitational waves and are of the same form as those describing the gravitational spin Hall effect of light, derived from Maxwell's equations.

description: This paper studies the energy efficiency of composable datacentre (DC) infrastructures over network topologies. Using a mixed integer linear programming (MILP) model, we compare the performance of disaggregation at rack-scale and pod-scale over selected electrical, optical and hybrid network topologies relative to a traditional DC. Relative to a pod-scale DC, the results show that physical disaggregation at rack-scale is sufficient for optimal efficiency when the optical network topology is adopted and resource components are allocated in a suitable manner. The optical network topology also enables optimal energy efficiency in composable DCs. The paper also studies logical disaggregation of traditional DC servers over an optical network topology. Relative to physical disaggregation at rack-scale, logical disaggregation of server resources within each rack enables marginal fall in the total DC power consumption (TDPC) due to improved resource demands placement. Hence, an adaptable composable infrastructure that can support both in memory (access) latency sensitive and insensitive workloads is enabled. We also conduct a study of the adoption of micro-service architecture in both traditional and composable DCs. Our results show that increasing the modularity of workloads improves the energy efficiency in traditional DCs, but disproportionate utilization of DC resources persists. A combination of disaggregation and micro-services achieved up to 23% reduction in the TDPC of the traditional DC by enabling optimal resources utilization and energy efficiencies. Finally, we propose a heuristic for energy efficient placement of workloads in composable DCs which replicates the trends produced by the MILP model formulated in this paper.

description: MYC is frequently overexpressed in many human malignancies including prostate cancer.  MYC accumulation is tightly regulated through transcriptional and post-translational mechanisms. Here, we demonstrate that a complex MYC/Protein Kinase A (PKA) signaling loop functions in prostate cancer cells.  We show that MYC up-regulates Protein Kinase A Catalytic subunit ? (PKAC?) transcription in human prostate cancer cells and mouse prostate cancers.  We further demonstrate that PKA positively regulates MYC by phosphorylating Ser279, thereby priming phosphorylation by Polo-like kinase 1 at Ser281 and protecting MYC from degradation. Consistent with this, brief pharmacologic pan-PKA inhibition diminishes MYC level.  Paradoxically however, prolonged Protein Kinase A Catalytic subunit α (PKAC α), but not PKAC?, knockdown increases MYC mRNA and protein levels, linking transcriptional repression of MYC with PKAC α activity, and revealing distinct functional roles among PKA catalytic isoforms in MYC regulation.  We demonstrate that this effect stems from differential substrate selectivity among PKA isoforms, providing a mechanistic understanding of differential MYC regulation by PKA.  Our observations establish PKA as a viable therapeutic target in MYC-overexpressing cancers, but highlight the risk of global PKA inhibition, underscoring the need to develop advanced inhibition strategies to disrupt specific kinase/substrate interactions.

description: Modeling episodes of heavy rain is an important component of hydrological studies. Based on the analysis of ship-borne radar data over the tropical ocean, we propose a new class of probability densities that capture the frequency of heavy rain occurrences. This density is constructed by inverting the characteristic function constructed from the moments computed at both integral and fractional orders, for all spatial scales. We demonstrate an improvement over the conventional log-normal distribution at explaining the behavior of intense rain events, and successfully explain the multiscaling characteristics of the rain field. An important assumption in the analysis of space-time characteristics of rain fields is isotropy and homogeneity. We test the equality of spectral densities at multiple locations in a non-parametric setting using the data periodograms. The efficacy of our methodology is demonstrated through simulation, and the theoretical properties of the proposed test statistic are examined. We establish the fact that the test asymptotically maintains the desired level of significance and is consistent at any alternative, and apply our methodology to real life rain rate data set taken from a network of rain gauges in Melbourne, South Florida. This research was supported by a NASA grant under the Precipitations Measurement Missions (PMM) program.

These cases illustrate the different ways in which such sum rules can be realized, and the varying mathematical techniques by which they can be confirmed. Using the same methods, we also evaluate the second-order energy shifts arising from the introduction of a constant external field, namely the Stark effect.

SOME ASPECTS OF MULTIVARIATE QUALITY CONTROL CHARTS FOR DISPERSION
Creators: name: Borrego Garza, Paula Patricia
Publisher: name: Maryland Shared Open Access Repository
Year: 2012
Subjects: Multivariate Quality Control

description: In multivariate quality control, we are looking for monitoring p characteristics simultaneously. Consider the variance covariance matrix. This matrix is symmetric and has the variances of each characteristic on the diagonal elements in the order X1, X2, ...,Xn.  Now, consider that the order of these characteristics is really arbi- trary. If two characteristics were considered, for instance, height and weight, there are actually two ways to arrange the variancecovariance matrix. If three characteristics are considered, six dierent orderings of the variance covariance matrices are possible. In this thesis we will study the consequences of rearranging the variance covariance matrix under a multivariate quality control setting; using the method of decomposition of the variance covariance matrix proposed by Tang and Barnett(1996) for p = 2; 3 and 4.

description: The interplay of non-trivial band topology and magnetism gives rise to a series of exotic quantum phenomena, such as the emergent quantum anomalous Hall (QAH) effect and topological magnetoelectric effect. Many of these quantum phenomena have local manifestations when the global symmetry is broken. Here, we report local signatures of the thickness dependent topology in intrinsic magnetic topological insulator MnBi$_2$Te$_4$(MBT), using scanning tunneling microscopy and spectroscopy on molecular beam epitaxy grown MBT thin films. A thickness-dependent band gap with an oscillatory feature is revealed, which we reproduce with theoretical calculations. Our theoretical results indicate a topological quantum phase transition beyond a film thickness of one monolayer, with alternating QAH and axion insulating states for even and odd layers, respectively. At an even-odd layer step, a localized gapped electronic state is observed, in agreement with an axion insulator edge state that results from a phase transition across the step. The demonstration of thickness-dependent topological properties highlights the role of nanoscale control over novel quantum states, reinforcing the necessity of thin film technology in quantum information science applications.

description: There are more and more applications of functional data analysis in recent years. Testing methodologies have received enormous attentions, especially in biomedical problems. The motivation of this work is to build statistical methodology for testing equality of functional data across groups. We concentrate on testing equality of the data structures based on latent features. The latent functional features are extracted from data by using a technique called Independent Component Analysis (ICA). GroupICA is modified version of ICA specifically for group inferences, and is applied in this work. After feature extraction, we perform our testing methods. Without much knowledge of data, bootstrapping and other data-driven testing procedures are considered, and we use Monte Carlo study to compare expected and empirical rejection levels. We use a modified Kolmogorov-Smirnov type statistics to test equality of marginal distributions of two or more stationary processes, and use spectral domain methods to develop a testing procedure for testing equality of second order dependence in those processes. In practice, we need the test to be robust against non-normal data, unknown dependence structure, different number of variables per group and unequal group sample sizes. We applied our methods in two bio-medical applications: 2D electrophoresis gels of protein and fMRI data analysis of simulated driving behavior.

description: For an integer $n>2$, a rank-$n$ matroid is called an $n$-spike if it consists of $n$ three-point lines through a common point such that, for all $k\in\{1, 2, ..., n - 1\}$, the union of every set of $k$ of these lines has rank $k+1$. Spikes are very special and important in matroid theory. In 2003 Wu found the exact numbers of $n$-spikes over fields with 2, 3, 4, 5, 7 elements, and the asymptotic values for larger finite fields. In this paper, we prove that, for each prime number $p$, a $GF(p$) representable $n$-spike $M$ is only representable on fields with characteristic $p$ provided that $n \ge 2p-1$. Moreover, $M$ is uniquely representable over $GF(p)$.

Black Holes at the LHC

description: In these two lectures, we will address the topic of the creation of small black holes during particle collisions in a ground-based accelerator, such as LHC, in the context of a higher-dimensional theory. We will cover the main assumptions, criteria and estimates for their creation, and we will discuss their properties after their formation. The most important observable effect associated with their creation is likely to be the emission of Hawking radiation during their evaporation process. After presenting the mathematical formalism for its study, we will review the current results for the emission of particles both on the brane and in the bulk. We will finish with a discussion of the methodology that will be used to study these spectra, and the observable signatures that will help us identify the black-hole events.

description: We compare the history of the galaxy mass build-up, as inferred from near-IR observations, and the Star Formation Rate of massive stars in the comoving volume traced by deep extensive far-IR surveys, both possible now with the Spitzer Space Telescope. These two independent and complementary approaches to the history of galaxy formation consistently indicate that a wide interval of cosmic epochs between z~0.7 to z~2 brackets the main evolutionary phases. The rate of the integrated galaxy mass growth indicated by the IR-based comoving SFR appears consistent with the observed decrease of the stellar mass densities with redshift. There are also indications that the evolution with z of the total population depends on galaxy mass, being stronger for moderate-mass, but almost absent up to z=1.4 for high-mass galaxies, thus confirming previous evidence for a "downsizing" effect in galaxy formation. The most massive galaxies appear already mostly in place by z~1. Although a precise matching of this galaxy build-up with the growth of nuclear super-massive black-holes is not possible with the present data (due to difficulties for an accurate census of the obscured AGN phenomenon), some preliminary indications reveal a similar mass/luminosity dependence for AGN evolution as for the hosting galaxies.

Taste breaking effects in scalar meson correlators

description: As a consistency check of the staggered-fermion fourth-root approximation, we analyze the a_0 and f_0 correlators, including the effects of two-meson taste-multiplet intermediate states. Rooted staggered chiral perturbation theory describes the contributions from the pseudoscalar taste multiplets in terms of only a few low energy constants, which have all been previously determined by the MILC collaboration. In previous work one of us (Prelovsek) showed that the two-meson ``bubble'' contributions could explain the observed anomalies in the lattice data for the isovector a_0 channel. In the present work we extend this analysis to the f_0 channel. On a MILC collaboration lattice ensemble at 0.12 fm with 2+1 flavors of Asqtad-improved staggered fermions, we have made new measurements of correlators in both channels for a variety of momenta. A fit to these correlators gives low energy constants that are reasonably consistent with previous determinations by the MILC collaboration.}

Parametrizations of the Spin Density Matrix

description: We propose for the spin density matrix two parametrizations which automatically fulfil the non-negativity conditions, without setting any bound on the parameters. The first one relies on a theorem, that we prove, and it is rather simple and easily adaptable to some specific reactions, where, for example, parity is conserved or angular momentum conservation entails selection rules. Moreover, in the case when the rank is less than the order of the density matrix, we show how to improve the fits to the data, either by implementing previous suggestions, or by elaborating an alternative method, for which we prove a second theorem. Our second parametrization is a variant of previous treatments, it appears suitable for some particular processes. Moreover, we discuss about the possibility of inferring the elements of the density matrix from the differential decay width. Last, we illustrate various examples of current interest, both in strong and weak decays; some of them may be helpful in the investigation of physics beyond the standard model.

description: The Rainbow operating system provides 64-Bit transactional memory operation for PC-clusters. Basic consistency of the distributed objects is guaranteed by an optimistic transactions scheme and weakened consistency models are available for application data structures. The Java-like language environment allows for binary isolation, compiler-based OS security and for clusterwide garbage collection. An optional pageserver will offer orthogonal persistence as well as subsecond restart and recovery.

Randomness in compressible fluid flows past an obstacle

description: We consider a statistical limit of solutions to the compressible Navier--Stokes system in the high Reynolds number regime in a domain exterior to a rigid body. We investigate to what extent this highly turbulent regime can be modeled by an external stochastic perturbation, as suggested in the related physics literature. To this end, we interpret the statistical limit as a stochastic process on the associated trajectory space. We suppose that the limit process is statistically equivalent to a solution of the stochastic compressible Euler system. Then, necessarily, (i) the stochastic forcing is not active -- the limit is a statistical solution of the deterministic Euler system; (ii) the solutions S-converge to the limit; (iii) if, in addition, the expected value of the limit process solves the Euler system, then the limit is deterministic and the convergence is strong in the $L^p$-sense. These results strongly indicate that a stochastic forcing may not be a suitable model for turbulent randomness in compressible fluid flows.
