Identifying Noise Traders: The Head-and-Shoulders Pattern in U.S. Equities

This paper identifies a specific set of agents as noise traders in U.S. equity markets, and examines their effects on returns. These agents, who speculate using the "head-and-shoulders" chart pattern, are shown to qualify as noise traders because (1) trading volume is exceptionally high when they are active, and (2) their trading is unprofitable. Head-and-shoulders sales lower prices and vice versa, effects that disappear within two weeks.
Insights into a historic severe haze event in Shanghai: synoptic situation,boundary layer and pollutants

Abstract. A historic haze event, characterized by lengthy, large-scale and severe pollution, occurred in the Yangtze River Delta (YRD) of China from 1 to 10 December 2013. This haze event significantly influenced air quality throughout the region, especially in urban areas. Aerosol physical, chemical and optical properties were measured in Shanghai. Sometimes the 1 h average particle concentration (e.g., PM2.5) exceeded 600 µg m−3. Inorganic water-soluble ions in particles, trace gases and aerosol optical coefficients had a similar tendency to increase evidently from clear to hazy episodes. A combination of various factors contributed to the formation and evolution of the haze event, among which meteorological conditions, local anthropogenic emissions and pollutants are the major factors. High pressure system, calm surface wind and subsidence airflow were responsible for the decrease of planetary boundary layer (PBL) and the accumulation of pollutants. Atmospheric visibility correlated strongly with relative humidity (RH), particle number in size of 600–1400 nm other than particulate water-soluble species and particle mass (PM2.5). The particle hygroscopicity plays an important role in atmospheric visibility reduction. The results are somewhat helpful to forecast and eliminate regional atmospheric pollution in China.
Rwanda's Orphans - Care and Integration During Uncertain Times

Children and youth are considered cornerstones of development in post-conflict state-building practices. In the case of Rwanda, the government has engaged in an ambitious state-initiated deinstitutionalization project that anticipates the closure of all officially registered orphanages between 2012 and 2014. As a consequence, all orphans within institutional care will return to their extended families or be placed with foster parents to be given the opportunity to grow up within a Rwandan family environment. By investigating the lived realities of orphans before their departure from the orphanage, it becomes apparent that there is no “one size fits all” approach to systems of child care as historical and psychosocial dynamics play a crucial role.
Does *alpha really matter? Evidence from mutual fund incubation, termination and manager change

This paper examines the importance of risk-adjusted versus total returns in mutual fund family investment offering and manager succession decisions. Incubated funds with higher total returns are more likely to be offered to the public, and seasoned funds with lower total returns are more likely to be terminated, but risk-adjusted returns are unrelated to these decisions. Managers with higher (lower) risk-adjusted performance are more likely to be promoted (demoted), but total returns are unrelated. These results provide a new perspective on the “puzzle” of active management and the role of risk-adjusted versus total returns in investor decision-making. * I am grateful for the comments and suggestions of Brian Bushee, David Chapman, Diane Del Guercio, Roger Edelen, Wayne Ferson, Chris Geczy, David Haushalter, Craig MacKinlay, Massimo Massa, Grant Marquee, Andrew Metrick, David Musto, Jeff Pontiff, Adam Reed, Robert Stambaugh, Phil Strahan and Jessica Watcher.

Inflammatory Myofibroblastic Tumors of the Genitourinary Tract : Etiology , Diagnosis , and Management

Since the discovery of alpha-methylacyl CoA racemase (AMACR) in prostate cancer in 2000, there have been a number of publications studying the diagnostic value of this enzyme. Although the role of this enzyme is still unknown, the application of AMACR immunohistochemistry in pathology practice has been increased sharply in the last few years. We are going to review the recent studies of the AMACR expression in prostate cancer and several benign and malignant entities by us and other investigators. Then we will discuss clinical application, limitation and pitfall of using this marker in details. This discussion is by no means a guidance for pathology practice, but it may provide some reference when interpretating AMACR immunostaining. INTRODUCTION Widespread use of PSA has resulted not only in increased number of prostate needle core biopsies performed each year, but also an increasing number of small foci of uncertain diagnoses of limited biopsy material (1-3). Although histological features of prostatic adenocarcinoma such as growth pattern, nuclear atypia, absence of basal cells, and presence of characteristic extra cellular material are important (4-5), when used alone, they are not entirely sensitive or specific to establish a definitive diagnosis of prostate cancer. Immunohistochemical stains for high-molecular weight keratins such as 34beta12 and more recently p63 have been used to identify basal cells which are typically present in benign glands but absent in prostatic adenocarcinoma (6-). Unfortunately, negative staining for basal cells in a few suspicious glands is not a definitive proof of malignancy, as benign conditions can have a patchy or discontinuous distribution of basal cells (8). Rarely, prostatic adenocarcinoma may also contain cells positive for basal cell markers. Therefore, a sensitive yet specific “positive” marker of prostatic adenocarcinoma would be very useful in raising the confidence level in diagnosis on limited specimens for prostate needle cores.
A statistical–numerical aerosol parameterization scheme

A new modal aerosol parameterization scheme, the statistical-numerical aerosol parameterization (SNAP), was developed for studying aerosol processes and aerosol- cloud interactions in regional or global models. SNAP ap- plies statistical fitting on numerical results to generate ac- curate parameterization formulas without sacrificing details of the growth kernel. Processes considered in SNAP include fundamental aerosol processes as well as processes related to aerosol-cloud interactions. Comparison of SNAP with nu- merical solutions, analytical solutions, and binned aerosol model simulations showed that the new method performs well, with accuracy higher than that of the high-order numer- ical quadrature technique, and with much less computation time. The SNAP scheme has been implemented in regional air quality models, producing results very close to those us- ing binned-size schemes or numerical quadrature schemes.
Therapeutic Applications of Utilizing Resident Stem Cells in Regenerative Medicine

Treating diseases using regenerative medicine holds a great promise with the development of various kinds of stem cells, be it embryonic stem cells, induce pluripotent cells or parthenogenetic stem cells. The above have a great limitation because of cost factor, number of personnel required along with need for immunotherapy with fear of transplant rejection for ESC’s. Thus in the therapies last decade how stem cells interact with their support niche, namely the microenvironment of stem cells has markedly improved our basics in this field. Hence therapies directed towards resident stem cells are already in clinical trials. They may be gradually used more extensively in regenerative medicine, chronic degenerative disease, obesity and cancer. Problems and challenges in this include assigning the tissue specificity of any intervention, to ensure quality of repair in long term along with avoiding side effects like carcinogenesis. Therapies involving developmental pathways like Wnt, Hedgehog or notch signaling may be teratogenic or carcinogenic. Having broader therapeutic window maybe justified in case of conditions like cancer. Most successful regenerative medicine treatment involving endogenous repair will prove to be combination therapies. Thus targeting the niche is complementary to approach, which targets stem cells directly and in long term apply those are different times to effect recovery on the basis of dynamics of stem cell–niche interactions.
Fuzzy Logic Control of Switched Reluctance Motor Drives

In this chapter, the electromechanical behavior of switched reluctance motor (SRM) is first modeled by analyzing the related nonlinear differential equations. In the model, the estimation of rotor speed is also considered. After modeling, the effects of torque ripple, radial force, and acoustic noise are investigated. As we know, torque ripple and acoustic noise are two of the main disadvantages of a switched reluctance motor. Thus, a fuzzy logic current compensator is proposed both for reducing the peak of radial force and for decreasing acoustic noise effects. In the parts that torque reduces, the fuzzy logic current compensator injects additional current for each phase current to overcome the torque ripple. Also, the fuzzy logic current compensator reduces speed estimation error. The speed estimation is carried out using a hybrid sliding mode observer which estimates the rotor position and speed for a wide speed range. These new approaches have been simulated using MATLAB/SIMULINK for a nonlinear model of switched reluctance motor. The simulation results indicate that proposed methods decrease the maximum radial force and the torque ripple while the maximum torque is preserved. Also, these results show that proposed methods will estimate the rotor position and speed with high precision for all speeds from near zero speeds up to rated speed. These procedures have the advantages of simple implementation on the every switched reluctance motor drive without extra hardware, low cost, high reliability, low vibration, and excellent perform‐ ance at long term. phase flux linkages and phase currents. The investigations conducted throughout this research have shown that a properly trained
The social costs of unemployment: accounting for unemployment duration

This article contributes to the literature on unemployment and well-being by investigating the linkage between personal life satisfaction and a macroeconomic indicator of the duration of unemployment. Using data for more than 50 000 individuals in 10 European countries, 1992–2002, we find that the social costs of unemployment, in terms of general unemployment's impact on life satisfaction, relate significantly and to a considerable extent to unemployment duration. It is thus not just the risk of becoming or staying unemployed that people worry about, but especially the prospect of staying long-term unemployed. This fear affects employed and unemployed people alike. Our findings provide a strong point for focusing labour market policies on long-term unemployment, in addition to considerations of human capital depreciation.
Optical properties of amorphous and polycrystalline stibnite (Sb2S3) films

A systematic optical absorption study near the fundamental absorption edge was carried out on both amorphous and polycrystalline films of Stibnite in the temperature range 90-320 K. Films were grown using naturally occurring single crystals of Stibnite. The optical band gap of thermally evaporated films which have the stoichiometry Sb 43 S 57 was determined to be direct and temperature dependant. The band gap of amorphous phase at any temperature is considerably less than that of crystalline ones. The temperature dependence of band gap in both the cases agrees well with Varshni formula. The optical gap at 0 K for amorphous and crystalline films were determined by fitting experimental data to Varshni formula to be 1.95 eV and 2.13 eV with the temperature coefficient of band gap -8.72 x 10 -4 eV/K and -7 x 10 -4 eV/K respectively. We strongly believe that the band gap value depends on the sulphur content in the films. The films of thickness greater than 2000 A show interference pattern in the transmission spectra. The optical constants n and k were determined using the interference fringes in the wavelength range 600 - 900 nm for film thickness 2000 - 8000 A. In both cases n and k show thickness dependence.
Respuesta productiva de Nannochloropsis oculata, cultivada en diferentes medios y su eficiencia como alimento para el rotífero Brachionus rotundiformis

An experiment was conducted to evaluate the effect of different culture media on the productive response and proximate composition of microalgae, Nannochloropsis oculata, and the sub- sequent effect of such microalgae on the productive response and proximate composition of the rotifer Brachionus rotundiformis. Mi- croalgae were cultured in different media: Guillard F/2 (control), an agricultural fertilizer, and an aquacultural fertilizer. Thereafter, such microalgae were used to feed rotifers. A better productive response was observed when microalgae were cultured in the agricultural fer- tilizer. In addition, the chemical proximate composition of microal- gae was influenced by the type of culture medium used. When used as natural food for rotifers, higher productive response was observed in those rotifers fed with microalgae previously cultured in the aqua- cultural fertilizer. Also, the proximate composition of rotifers was influenced by the type of microalgae they consumed. In conclusion, the productive response and quality of microalgae depended on the medium in which they grew; also, the productive response and proxi- mate composition of rotifers depended upon the nutritional quality of N. oculata.
Fourier expansions for Eisenstein series twisted by modular symbols ( Draft )

Modular symbols have been very useful tools historically and are of significant interest in their own right. Merel in [11], for instance, used modular symbols extensively in his proof that the number of torsion points on an elliptic curve over an arbitrary number field is bounded, and that the bound depends only on the degree of the number field. Another very important use of modular symbols is in Cremona’s algorithms for elliptic curves [1] which he used to generate his tremendously influential databases of elliptic curves. His algorithms are based on the duality between cusp forms and modular symbols, and the resulting action of the Hecke operators on modular symbols. All the information about elliptic curves he derives is obtained by examining the corresponding spaces of modular symbols. There has also been considerable interest in statistical questions regarding modular symbols because they are connected to central values of L-functions. Let χ be a Dirichlet character of conductor m, and define Lf (s, χ) for Re(s) > 2 via the series
The Accrual Anomaly: International Evidence

We consider stock markets in 20 countries to investigate whether the accrual anomaly (Sloan 1996), characterized by U.S. stock prices overweighting the role of accrual persistence, is a local manifestation of a global phenomenon.We explore whether the occurrence of the anomaly is related to country differences in accounting and institutional structures, and examine alternative explanations for its occurrence. We find stock prices overweight accruals in general, with accruals overweighting occurring in countries with a common law relative to a code law tradition. Using firmlevel data on a country‐by‐country basis, we document the occurrence of the anomaly in four countries, Australia, Canada, the U.K., and the U.S., and also in a sample of American Depository Receipts (ADRs) of firms domiciled in countries where we do not detect the anomaly. Using country‐level data, we confirm the anomaly is more likely to occur in countries having a common law tradition, and also in countries allowing extensive use of ac.
Transition Cow Management : Focus on Regrouping Strategies

The period from three weeks before to three weeks after parturition in dairy cows, also known as the transition period, is characterized by significant changes in hormonal profile, feed intake, nutrient requirements, metabolism, and energy balance. These changes are known to dramatically affect immune function. In this manuscript we will discuss the physiological changes that affect immune function and we will discuss situations that accentuate immune suppression and predispose cows to health disorders. We will also evaluate how to improve health of transition cows through management in order to reduce health disorders and improve reproductive efficiency.

An Exploratory Study on Risk Factors of Malnutrition in Children: A Cross-Sectional Study based on Slummy Areas of Lahore

This study focuses on the most important hazards of malnutrition (specifically related to underweight in this study) among the children resident in slummy areas of Lahore. It includes children of 6 months to 5 years of age randomly selected from localities of Lahore. It includes 361 children of both genders. Assessment of malnutrition was done by anthropometric measures; z-scores and percent of median. The cases are defined as any child below -2 SD from median weight for his/her age and the controls are defined as any child above -2 SD from median weight for his/her age as plotted on the growth chart by WHO. Multiple Logistic Regression (MLR) is applied for evaluation of significant risk factors of malnutrition. Father’s education, health condition of child at time of birth, starvation, feeding practices and sanitary system were found to risk factors of malnutrition. The problem should be addressed and should be spread among people. Government should take some steps by facilitating people with fundamental needs such as hygienic water, vaccination, health facilities, etc.
Comparison of the determination of drugs with influence on driving performance in serum , whole blood and dried blood spots

A total of 29,700 cases of driving under the influence of drugs (DUID) has been registered in Germany in 2009 [1]. In these cases, a blood sample is regularly taken by a medicinal practitioner, which may cause a significant delay. Hence, the blood concentration may no longer reflect actual impairment. Roadside sampling is considered to be most advantageous over blood collection at the police office.
Additional records of non-native freshwater fishes for the Ebro River basin (Northeast Spain)

This paper extends the knowledge of the geographical distribution of non-native freshwater fishes in the Ebro River basin (Spain). More than two hundred surveys were carried out since 2000, and thirteen non-native fish species were collected on fifty- eight occasions. The spread of most of the recorded non-native species seems to be a consequence of illegal introductions related to sport fishing activities and the subsequent natural dispersal. Their presence could impact natural populations of Iberian native -mostly endemic- freshwater fish species, through direct predation and competition for niche and/or trophic resources.
Coffee arabica complies Chemo-preventive Activity against DMH-induced Colorectal Cancer in Experimental Rat Model

The aim of this study was to evaluate chemopreventive potential of Coffee arabica in DMH-induced colorectal carcinogenesis in the rat model. Totally, 35 female wistar rats were divided into seven equal groups. Groups I-VII except group VI were given freshly prepared neutral DMH in normal saline, once a week for 5 weeks. Group VI received normal saline alone. Groups II and III received oral dose of coffee every time when they are given DMH. Groups IV and V received coffee after 5 months of DMH treatment. Group VII was treated with aspirin. Multiple plaque lesions, aberrant crypts and aberrant crypt foci were observed in colorectal walls of the DMH alone treated rat groups. The numbers of preneoplastic features were significantly reduced in coffee or aspirin treated groups. Histologically, different degree of dysplasia and hyperplasia was observed in DMH alone group. The above features were significantly reduced in coffee or aspirin treated groups. Serum biomarkers and body weight of DMH-induced colorectal cancer were appreciably maintained in coffee and aspirin treated groups. Taken together, the results of this study revealed that Coffee arabica has significant effect on reducing the number of preneoplastic lesions and polyps, considerably suppressing tumor progression and invasion.
