From Efficient Market Hypothesis To Swing Market Hypothesis

This paper presents a joint review on professional technical analysis and academic quantitative analysis of the financial markets, aiming at bridging the deep gulf between the two fields and unifying them under a general science of intelligent finance or financial intelligence. While econometricians and econophysicians have recently reexamined technical analysis, most of their effort is focused on chart patterns and technical indicators, leading to some simplicity impression of technical analysis. In our view, the most valuable core and also the hardest part of technical analysis is the fractal and quantum nature of Elliott waves and Gann price-time cycles and angles. On the quantitative analysis side, since Mandelbrot's discovery of fractals in financial time series, both empirical and fundamental progresses have been made, mainly in the last decade, including a third-order power law asymptotic behavior in return distribution, an accelerated crossover from the power law towards a Gaussian, a theoretical framework of crashes as critical points, and multi-agent game models of the financial markets. Inspired by these developments from the two fields we point out the possibility of developing an adaptive computational model of Elliott waves and Gann price-time cycles and angles using multilevel power laws, log-periodicity and instantaneous phase estimation.
3 The Poor Countries ’ International Financial Transactions

Poor countries have benefited from the growth of global capital flows T he globalization of production and financial services has provided the opportunity for poor countries to increase their reliance on private sector international financial transactions. 1 Poor countries lack access to capital markets and official flows have fallen, while total aid has declined along with the share of the poor countries. However, foreign direct investment (FDI) flows have risen substantially: while the poor countries remain dependent on official external finance, they now receive the same amount of FDI as other developing countries, in relation to the size of their economies (table 3.1). FDI flows to the poor countries have become more diversified: the share of the mineral-and oil-exporting countries in total FDI to the poor countries fell from almost half in 1991 to 20 percent in 1997. Poor countries have participated in the global expansion of commercial banks: foreign banks' assets now account for 40 percent of total bank assets in the poor countries, twice as high as in 1995. Despite capital controls, poor countries' residents have placed significant amounts of capital abroad: the stock of capital outflows from the poor countries were larger relative to cumulated domestic savings and the stock of reserves, and only slightly smaller relative to gross domestic product (GDP), than outflows from other developing countries. As in middle-income countries, the quality of the investment climate determines the extent of poor countries' access to capital and the extent to which foreign capital benefits the domestic economy. Countries with sound investment climates tend to attract more FDI, limit capital outflows, and enjoy greater productivity of both foreign and domestic capital than countries with weak invest-55. ment climates. Those countries that established the stable macroeconomic policies and effective regulatory regimes necessary to attract foreign bank participation increased the access of domestic banks to trained personnel and technological advances, while rising competition from foreign banks helped reduce the costs of financial intermediation. Poor countries' greater openness to capital flows means that they have to cope with the macroeconomic effects of capital mobility. Sustainable macroeconomic policies marked by low inflation and debt levels are essential to limit capital outflows, and sharp changes in outflows (or capital repatriation) can complicate efforts at stabilization. Financial integration has increased since the 1980s The poor countries' private international financial transactions increased substantially during the 1990s. Official flows have fallen with the decline in …
Assessing Performance Impacts in Food Retail Distribution Systems: A Stochastic Frontier Model Correcting for Sample Selection

A key organizational decision for retailers is whether to self-distribute or rely on a wholesaler-supplied network and yet little is known about the impact of this strategic choice on store-level productivity. We estimate a stochastic frontier model for food retailers that accounts for selectivity effects linked to the choice of distribution strategy. We find that adoption of data-sharing technologies has a positive impact on store-level gross margins of stores in self-distributing chains. Technical inefficiency among U.S. food retailers leads to a gross margin that is around $5,000 less for a conventional food retailer and about $7,670 less for a supercenter.
Autoimmune Dysregulation and Purine Metabolism in Adenosine Deaminase Deficiency

Genetic defects in the adenosine deaminase (ADA) gene are among the most common causes for severe combined immunodeficiency (SCID). ADA-SCID patients suffer from lymphopenia, severely impaired cellular and humoral immunity, failure to thrive, and recurrent infections. Currently available therapeutic options for this otherwise fatal disorder include bone marrow transplantation (BMT), enzyme replacement therapy with bovine ADA (PEG-ADA), or hematopoietic stem cell gene therapy (HSC-GT). Although varying degrees of immune reconstitution can be achieved by these treatments, breakdown of tolerance is a major concern in ADA-SCID. Immune dysregulation such as autoimmune hypothyroidism, diabetes mellitus, hemolytic anemia, and immune thrombocytopenia are frequently observed in milder forms of the disease. However, several reports document similar complications also in patients on long-term PEG-ADA and after BMT or GT treatment. A skewed repertoire and decreased immune functions have been implicated in autoimmunity observed in certain B-cell and/or T-cell immunodeficiencies, but it remains unclear to what extent specific mechanisms of tolerance are affected in ADA deficiency. Herein we provide an overview about ADA-SCID and the autoimmune manifestations reported in these patients before and after treatment. We also assess the value of the ADA-deficient mouse model as a useful tool to study both immune and metabolic disease mechanisms. With focus on regulatory T- and B-cells we discuss the lymphocyte subpopulations particularly prone to contribute to the loss of self-tolerance and onset of autoimmunity in ADA deficiency. Moreover we address which aspects of immune dysregulation are specifically related to alterations in purine metabolism caused by the lack of ADA and the subsequent accumulation of metabolites with immunomodulatory properties.
On Gross Worker Flows in the United Kingdom: Evidence from the Labour Force Survey

Empirical studies of worker flows in the United States and Europe have found that these flows are large when compared with the change in the stocks of employment and non-employment, and have a distinct cyclical pattern. In the United Kingdom, studies of this kind have been hampered by limitations in the available data. In this paper use is made of newly released longitudinal data from the Labour Force Survey. It is shown that, on average, since 1993 7.3% of those in the working-age population have changed labour market state in a given three-month period. This compares with a consistently calculated annual figure of 12.5%. In addition, an array of evidence is presented to show that UK gross flows appear to follow a cyclical pattern similar to those found in other countries. Evidence is also presented on the potential problems that previous research may suffer from with their use of recall data to determine prior labour market status. While stocks are similar using recall or recorded labour market state, flows inferred from recall data are severely biased by recall error.
Ita-Coin: A New Coincident Indicator for the Italian Economy

In this paper we present a coincident indicator for the Italian economy, Ita-coin. We construct a multivariate filter based on a broad information set, whose dimension is reduced by the Generalized Dynamic Factor Model (GDFM) approach proposed by Forni et al. (2002). A regression based on the least absolute shrinkage and selection operator (LASSO) is used to estimate Ita-coin. Most Italian macroeconomic indicators are characterized by high short-term volatility and the 2008-2009 crisis has affected the volatility of both the high- and low-frequency components and the relationships between the variables have become more unstable. LASSO regression allows us to select recursively the relevant information about the comovement of the variables over time. Our indicator displays a satisfactory performance in the pseudo real-time validation as a timely cyclical indicator.
Economic Development Strategies: Examples from Europe and Australia

By looking at very different aspects of regional economic development theory and policy as well as geographical areas, this paper provides a foundation of economic strategies applicable to many regions. The focus is set on a flexible and holistic approach to be able to include a wide range of economic development and wellbeing indictor and to offer an alternative to the neoclassical development framework. The European regional policy is used as an example to analyse policy in a theoretical economic development framework. The Australian example is a practical case study of a small rural shire showing the issues individual regions are facing when they are dealing with regional development on a local level.
FPGA Based Efficient Cholesky Decomposition for Solving Least Square Problem

The paper presents FPGA based design & implementation of Cholesky Decomposition for matrix calculation to solve least square problem. The Cholesky decomposition has no pivoting but the factorization is stable. It also has an advantage that instead of two matrices, only one matrix multiplied by itself. Hence it requires two times less operation. The Cholesky decomposition has been designed & simulated using DSP tool & it has been synthesized using Xilinx synthesis tool on Virtex 5 XCVLX330 FPGA. The existing LUTs of target FPGA have been optimally utilized to reduce the area consumption & to enhance the speed. It has been observed from the synthesis results that proposed design is capable of reducing slices by 73.55% and LUTs by 60%. An improvement of 3.40% in speed is also achieved as compared to existing design. Index Terms — Cholesky Decomposition, FPGA, LU Decomposition, Matrix factorization.

Turbo-detected unequal protection MPEG-4 wireless video telephony using trellis coded modulation and space-time trellis coding

A jointly optimised turbo transceiver capable of providing unequal error protection is proposed for MPEG-4 aided wireless video telephony. The transceiver advocated consists of Space-Time Trellis Coding (STTC), Trellis Coded Modulation (TCM) and two different-rate Non-Systematic Convolutional codes (NSCs). A benchmarker scheme combining STTC and NSC is used for comparison with the proposed scheme. The video performance of the both schemes is evaluated when communicating over uncorrelated Rayleigh fading channels. It was found that the proposed scheme requires about two dBs lower transmit power than the benchmarker scheme in the context of the MPEG-4 videophone transceiver, when aiming for an effective throughput of 2 bits/symbol at a similar decoding complexity.
Understand Your Chains: Towards Performance Profile-Based Network Service Management

Allocating resources to virtualized network functions and services to meet service level agreements is a challenging task for NFV management and orchestration systems. This becomes even more challenging when agile development methodologies, like DevOps, are applied. In such scenarios, management and orchestration systems are continuously facing new versions of functions and services which makes it hard to decide how much resources have to be allocated to them to provide the expected service performance. One solution for this problem is to support resource allocation decisions with performance behavior information obtained by profiling techniques applied to such network functions and services. In this position paper, we analyze and discuss the components needed to generate such performance behavior information within the NFV DevOps workflow. We also outline research questions that identify open issues and missing pieces for a fully integrated NFV profiling solution. Further, we introduce a novel profiling mechanism that is able to profile virtualized network functions and entire network service chains under different resource constraints before they are deployed on production infrastructure.
The z = 2.51 Extremely Red Submillimeter Galaxy SMM J04431+0210

We report the redshift measurement for the submillimeter selected galaxy SMM J04431+0210 (N4) using the Near Infrared Spectrograph on the Keck II Telescope. The data show Hα, [N II] λλ6583, 6548, and [O III] λ5007 lines at a redshift of z = 2.51. The high nuclear [N II]/Hα line ratio is consistent with a LINER or type II active galactic nucleus (AGN). The Hα emission is spatially resolved, suggesting the presence of significant star-forming activity outside the nucleus. From imaging with the Near Infrared Camera on the Keck I Telescope, we find an extremely red near-infrared color of J-K = 3.2 for N4. Follow-up redshifted CO(3→2) observations with the Owens Valley Millimeter Array constrain the mass of molecular gas to be less than 4 × 1010 M⊙, after correcting for lensing. The CO-to-submillimeter flux limit, the spectroscopic line ratios, and the spectral energy distribution for N4 are all within the range of properties found in other high-redshift submillimeter sources and local ultraluminous infrared galaxies. After the correction for lensing, N4 is the weakest intrinsic submillimeter-selected source with a known redshift and represents the first redshift for the under 2 mJy 850 μm sources that are responsible for the bulk of the emission from the submillimeter population as a whole. We argue that N4 contains either an AGN or LINER nucleus surrounded by an extended region of active star formation.
Specificity and stability in high latitude eastern Pacific coral‐algal symbioses

The Gulf of California (Sea of Cortez) acts as a refuge for zooxanthellate coral communities at high northern latitudes in the eastern Pacific. The diversity of dinoflagellate endosymbionts living with cnidarians (9 genera, 16 species) was examined using denaturing gradient gel electrophoresis (PCR‐DGGE) fingerprint analysis of the rDNA Internal Transcribed Spacers (ITS) 1 and 2. Although geographically isolated from the rest of the Pacific, coral‐algal associations in the Gulf of California were similar in cladal composition (dominated by clade C Symbiodinium). However, levels of host‐symbiont specificity appeared to be greater than in the western Pacific, where host diversity is considerably higher and environmental conditions are relatively stable. As a result, the cnidarian community lacked a host‐generalist symbiont. Most colonies of the ecologically dominant genus Pocillopora contained uniform populations of either Symbiodinium D1 (in ~70% of colonies) or C1b‐c (~30%). The proportions of D versus C colonies (i.e., D and C holobionts) remained stable between the years 2004 and 2006. The specificity, stability, and prevalence of Symbiodinium D1 found among individuals of Pocillopora spp. in a region minimally impacted by coral bleaching indicate that these symbiotic combinations, exhibiting specific variability, appear to be products of long‐term ecological and evolutionary processes.
Continuum modeling of dislocation plasticity: Theory, numerical implementation, and validation by discrete dislocation simulations

Miniaturization of components and devices calls for an increased effort on physically motivated continuum theories, which can predict size-dependent plasticity by accounting for length scales associated with the dislocation microstructure. An important recent development has been the formulation of a Continuum Dislocation Dynamics theory (CDD) that provides a kinematically consistent continuum description of the dynamics of curved dislocation systems [T. Hochrainer, et al., Philos. Mag. 87 , 1261 (2007)]. In this work, we present a brief overview of dislocation-based continuum plasticity models. We illustrate the implementation of CDD by a numerical example, bending of a thin film, and compare with results obtained by three-dimensional discrete dislocation dynamics (DDD) simulation.
Understanding Data Sharing in Private Personal Clouds

Data sharing in Personal Clouds blurs the lines between on-line storage and content distribution with a strong social component. Such social information may be exploited by researchers to devise optimized data management techniques for Personal Clouds. Unfortunately, due their proprietary nature, data sharing is one of the least studied facets of these systems. In this work, we present the first study of data sharing in a private Personal Cloud. Concretely, we contribute a dataset collected at the metadata back-end of NEC: an enterprise oriented Personal Cloud. First, our analysis provides a deep inspection of the storage layer of NEC, comparing it with a well-known public vendor (UbuntuOne). Second, we study the social structure of NEC user communities, as well as the storage characteristics of user sharing links via multiplex network techniques. Finally, we discuss a battery of data management optimizations for NEC derived from our findings, which may be of independent interest for other similar systems. Our proposals include content distribution, caching and data placement. We believe that both our study and dataset will foster further research in this field.
Open Economy Macroeconomics in Developing Countries

This rigorous and comprehensive textbook develops a basic small open economy model and shows how it can be extended to answer many important macroeconomic questions that arise in emerging markets and developing economies, particularly those regarding monetary, fiscal, and exchange rate issues. Eschewing the complex calibrated models on which the field of international finance increasingly relies, the book teaches the reader how to think in terms of simple models and grasp the fundamentals of open economy macroeconomics. After analyzing the standard intertemporal small open economy model, the book introduces frictions such as imperfect capital markets, intertemporal distortions, and nontradable goods, into the basic model in order to shed light on the economy’s response to different shocks. The book then introduces money into the model to analyze the real effects of monetary and exchange rate policy. It then applies these theoretical tools to a variety of important macroeconomic issues relevant to developing countries and, in a world of continuing financial crisis, to industrial countries as well), including the use of a nominal interest rate as a main policy instrument, the relative merits of flexible and predetermined exchange rate regimes, and the targeting of “real anchors. ” Finally, the book analyzes in detail specific topics such as inflation stabilization, “dollarization,” balance of payments crises, and, inspired by recent events, financial crises. Each chapter includes boxes with relevant empirical evidence and ends with exercises. The book is suitable for use in graduate courses in development economics, international finance, and macroeconomics.
GXXXG and AXXXA: common alpha-helical interaction motifs in proteins, particularly in extremophiles.

The GXXXG motif is a frequently occurring sequence of residues that is known to favor helix-helix interactions in membrane proteins. Here we show that the GXXXG motif is also prevalent in soluble proteins whose structures have been determined. Some 152 proteins from a non-redundant PDB set contain at least one alpha-helix with the GXXXG motif, 41 +/- 9% more than expected if glycine residues were uniformly distributed in those alpha-helices. More than 50% of the GXXXG-containing alpha-helices participate in helix-helix interactions. In fact, 26 of those helix-helix interactions are structurally similar to the helix-helix interaction of the glycophorin A dimer, where two transmembrane helices associate to form a dimer stabilized by the GXXXG motif. As for the glycophorin A structure, we find backbone-to-backbone atomic contacts of the C alpha-H.O type in each of these 26 helix-helix interactions that display the stereochemical hallmarks of hydrogen bond formation. These glycophorin A-like helix-helix interactions are enriched in the general set of helix-helix interactions containing the GXXXG motif, suggesting that the inferred C alpha-H.O hydrogen bonds stabilize the helix-helix interactions. In addition to the GXXXG motif, some 808 proteins from the non-redundant PDB set contain at least one alpha-helix with the AXXXA motif (30 +/- 3% greater than expected). Both the GXXXG and AXXXA motifs occur frequently in predicted alpha-helices from 24 fully sequenced genomes. Occurrence of the AXXXA motif is enhanced to a greater extent in thermophiles than in mesophiles, suggesting that helical interaction based on the AXXXA motif may be a common mechanism of thermostability in protein structures. We conclude that the GXXXG sequence motif stabilizes helix-helix interactions in proteins, and that the AXXXA sequence motif also stabilizes the folded state of proteins.
