Book‐to‐Market Equity, Distress Risk, and Stock Returns

This paper examines the relationship between book-to-market equity, distress risk, and stock returns. Among firms with the highest distress risk as proxied by Ohlson's (1980) O-score, the difference in returns between high and low book-to-market securities is more than twice as large as that in other firms. This large return differential cannot be explained by the three-factor model or by differences in economic fundamentals. Consistent with mispricing arguments, firms with high distress risk exhibit the largest return reversals around earnings announcements, and the book-to-market effect is largest in small firms with low analyst coverage.

An Investigation into Engineering ESP Textbooks from Instructors’ Perspective: Critical Thinking in Focus

This study is an attempt to evaluate, through a qualitative design, engineering ESP (English for Specific Purposes) textbooks taught to students of Engineering with a focus on critical thinking skill. A typical ESP textbook taught in Iran consists of 15 units, starting with a text, comprehension, vocabulary, and several production exercises. The purpose of this study is to evaluate ESP textbooks and present four ESP instructors’ opinions with respect to critical thinking as a fundamental need for students of engineering. To this end, a semi-structured interview was exploited to probe the books and through content analysis, instructors’ opinions were categorized and their commonalities were extracted grounded on five main themes of the WGCTA (Watson-Glaser Critical Thinking Appraisal). The results of the content analysis indicated that there was a general consensus among the instructors that these textbooks do not rightly address the needs of learners in terms of enhancing their critical thinking skill; therefore, certain suggestions were provided by the instructors to improve the books. The findings promise implications for reflection in ESP instruction and materials development.
Medicinal and Pharmaceutical Potentialities of Tea ( Camellia sinensis L.)

Summary Tea is among the most widely consumed beverages in the world. There are three types of tea depending on the level of fermentation, i.e., green (unfermented), oolong (partially fermented) and black (fermented) tea. Many health benefits of various types of tea have been known up to present time. In general, green tea has been found to be superior to black tea in terms of antioxidant activity owing to the higher content of (−)'epigallocatechin gallate. The processes used in the manufacture of black tea are known to decrease levels of the monomeric catechins to a much greater extent than the less severe conditions applied to other teas. In the present review, we have discussed the current state of the science with regard to laboratory studies on various types of tea and some of health disorders including some types of cancer, coronary heart disease, atherosclerosis, metabolic syndrome, diabetes, resistance to insulin hypertension and obesity have been discussed.
Global nonlinear output regulation : Convergence-based controller design

In this paper we present output-feedback controllers solving the global output regulation problem for a class of nonlinear systems. The proposed controllers are based on the notion of convergent systems. The presented solution extends well-established results on the linear output regulation problem and the local nonlinear output regulation problem to the global case. For Lur’e systems, which are not necessarily in the output-feedback form, the proposed controllers can be found by solving the regulator equations and certain linear matrix inequalities. For systems in the output-feedback form with uncertain parameters and uncertain nonlinearities we provide a robust regulator that does not rely on the minimum phaseness assumption on the system, which is crucial in the previous regulator designs for output-feedback systems. The results are illustrated by examples. 2006 Elsevier Ltd. All rights reserved.
BUDKER INSTITUTE OF NUCLEAR PHYSICS B.A. Knyazev FEASIBILITY OF NON-LIOUVILLEAN ION INJECTION VIA RESONANTLY ENHANCED PHOTOIONIZATION

Charge-exchange method is now one of the main techniques for ion injection into accelerators and storage rings. Disadvantages of conventional methods, based on the atom or ion stripping at the material target, are growth emit­ tance and energy struggling. In this paper a variant of stripping technique based on the resonantly enhanced two-photon ionization is considered. The technique allows ionization of singly charged ions of the elements from he­ lium to bismuth. The technique can be also employed for proton injection. Numerical examples are given for several elements. o B03MO:>KHOCTH HeJIHYBHJIeBCKOH HH)KeKIJ;HH HOHOB c nOMOm;blO pe30HaHCHo-ycHJIeHHOA <pOTOHOHH38IJ;HH
Arctic Ocean circulation and weathering inputs over the past 15 million years

[1] Lead (Pb), neodymium (Nd), and strontium (Sr) isotopic analyses were carried out on sediment leachates (reflecting the isotope composition of past seawater) and digests of the bulk residues (reflecting detrital continental inputs) of Integrated Ocean Drilling Program (IODP) Leg 302 and core PS2185 from the Lomonosov Ridge (Arctic Ocean). Our records are interpreted to reflect changes in continental erosion and oceanic circulation, driven predominantly by tectonic forcing on million-year timescales in the older (pre-2 Ma) part of the record and by climatic forcing of weathering and erosion of the Eurasian continental margin on thousand-year timescales in the younger (post-2 Ma) part. These data, covering the past 15 Ma, show that continental inputs to the central Arctic Ocean have been more closely linked to glacial and hydrological processes occurring on the Eurasian margin than on continental North America and Greenland. The constancy of the detrital input signatures supports the early existence of an Arctic sea ice cover, whereas the major initiation of Northern Hemisphere glaciation at 2.7 Ma appears to have had little impact on the weathering regime of the Eurasian continental margin.
Optical properties of human stomach mucosa in the spectral range from 400 to 2000 nm

The optical properties of human stomach wall mucosa were measured in the wavelength range 400-2000 nm. The measurements were carried out using the commercially available spectrophotometer CARY-2415 with an integrating sphere. The combined method based on inverse adding-doubling and inverse Monte Carlo techniques was used to determine the absorption and scattering coefficients and anisotropy factor from the measurements.
Rashba spin-orbit-coupled atomic Fermi gases

We investigate theoretically BEC-BCS crossover physics in the presence of Rashba spin-orbit coupling in a system of a two-component Fermi gas with and without a Zeeman field that breaks the population balance between the two components. A bound state (Rashba pair) emerges because of the spin-orbit interaction. We study the properties of Rashba pairs using standard pair fluctuation theory. At zero temperature, the Rashba pairs condense into a macroscopic mixed-spin state. We discuss in detail the experimental signatures for observing the condensation of Rashba pairs by calculating various physical observables which characterize the properties of the system and can be measured in experiment.
A Potentially Useful Marker to Determine Left Ventricular Dysfunction in Patients with Left Bundle Branch Block with Dilated Cardiomyopathy: Tpeak-Tend

Introduction: It has been shown in various epidemiological studies that left bundle branch block (LBBB) is an independent risk factor of cardiac mortality. In this study, we aimed to examine the relationship between left ventricular function in patients with LBBB and the Tpeak-Tend (Tp-e) interval, which can be easily measured using electrocardiography (ECG) when patients are admitted to the hospital. Patients and Methods: In this study, 56 patients with LBBB were retrospectively selected according to their echocardiographic findings by using the retrospective scanning method. In line with this selection, patients were divided into two groups: patients with ejection fraction (EF) < 50% (32.4 ± 3.7) and those with EF > 50% (58.2 ± 4.1). Tp-e/corrected Tp-e (cTp-e) intervals were measured using the surface electrocardiogram technique. Results: According to our results, a negative correlation between Tp-e and EF in patients with LBBB and dilated cardiomyopathy (DCMP) (r= -0.723, p= 0.0001). Tp-e had a positive correlation with left ventricular end-diastolic diameter (LVEDd) (r= 0.394, p= 0.035) and with left ventricular end-systolic diameter (LVESd) (r= 0.478, p= 0.009). In the correlation analysis, we observed a negative correlation between cTp-e and EF values (r= -0.649, p= 0.0001), and cTp-e had a positive correlation with LVEDd (r= 0.587, p= 0.001) as well as with LVESd (r= 0.558, p= 0.002). Conclusion: Consequently, Tp-e/cTp-e interval can be a useful parameter that can be used particularly in the determination and follow-up of the patients whose left ventricular functions have not yet been deteriorated. Furthermore, this value can be used to select patients who can benefit from the treatment and to select the optimal timing of resynchronization therapy.
Nonlinear system modelling: how to estimate the highest significant order

A new method for estimating the highest significant order of nonlinearity of Volterra type systems is presented. The method is based on the use of multisine signals and the possibility of testing the system at three different amplitudes. The performance of the proposed method is demonstrated in simulation and it is shown that it is possible to estimate the highest order of nonlinearity of Volterra type systems very accurately. The method can be used to provide essential prior knowledge about the nonlinearity and thus aid the accurate representation of the system under test.
The use of bioflocculant and bioflocculant-producing Bacillus mojavensis strain 32A to synthesize silver nanoparticles

It is preferable to use an organism to produce more than one product at the same time. So, the aim of this study was to investigate the ability of bioflocculant-producing Bacillus mojavensis strain 32A as a nanosilver synthesizer beside bioflocculant production. To achieve this target, three media, nutrient broth, bioflocculant-producing medium, and pure bioflocculant, were tested. Produced nanosilver was characterized by UV-vis, XRD, and TEM. In all cases, the results demonstrated that UV-vis showed a peak at ∼420 nm corresponding to the plasmon absorbance of nanosilver. XRD spectrum exhibited 2θ values corresponding to the silver nanocrystal that is produced in hexagonal and cubic crystal configurations. TEM confirmed formation, size, shape, and morphologies of nanosilver particles. The results emphasized that purified bioflocculant has the ability to produce anisotropy clusters of nanosilver ranging in size from 6 to 72 nm proving that the bioflocculant functioned as reducing and stabilizing agent in nanosilver synthesis.
Arabs Want Democracy, but What Kind?

In recent times, Arabs have shown the world that they are ready for additional democratic reforms. We must nevertheless question what democracy means to them. How do they think about the role of religious leaders in democracy? Does democracy imply extending the rights of women? How do Arabs see the connection between democracy and a prosperous economy? Answers to these and similar questions are important in order to interpret the high levels of support for democracy that are being observed in the Arab world, as well as the possible outcomes of the Arab spring. It is also important to examine whether Arabs have a common understanding of democracy or whether they disagree on the form that democracy should take. Wide variations in the meaning of democracy could retard the process of democratization. In this article, public opinion data from Egypt, Iraq, Jordan, and Morocco are used to develop a detailed image of what democracy means to Arabs.
FOR BLOCKCHAIN APPLICATIONS IN MANUFACTURING SMALL AND MEDIUM SIZED ENTERPRISES

Blockchain technology is rising towards the peak of inflated expectations according to Gartner's 2016 Hype Cycle for Emerging Technologies. A public ledger that enables low cost, near real-time, secure and timestamped transactions in a peer-to-peer network of participants without the need for a trusted third party offers great potentials for networks of cooperating companies of the manufacturing industry. Therefore, in this paper presents a definition and recent developments of the blockchain technology as well as evaluates existing applications with respect to the suitability for manufacturing companies. Furthermore, requirements for implementation of applications in manufacturing SMEs are derived to support the advancing digitization of industries.
Struggle against Difficulties in Artificial Intelligence

Power flow analysis of Rafah governorate distribution network using ETAP software

The results of a load flow analysis can be used for operational purposes to evaluate various operating states of an existing system. They can also be used in the planning stages to evaluate possible future extension projects. This paper discusses the analysis of the power distribution network in Rafah governorate by using ETAP software. The aim is to evaluate the technical status of the present medium voltage network (22-kV). The problems and challenges faced by the existing network are analyzed. Those problems include the power deficit, high power losses, poor voltage levels and feeders’ overloading. Then some solution techniques are suggested considering the system current state and future growth for different scenarios for each problem to obtain a full understanding of the system problems and solutions.
Adaptive Aggregating Multiresolution Feature Coding for Image Classification

The Bag of Visual Words (BoW) model is one of the most popular and effective image classification frameworks in the recent literature. The optimal formation of a visual vocabulary remains unclear, and the size of the vocabulary also affects the performance of image classification. Empirically, larger vocabulary leads to higher classification accuracy. However, larger vocabulary needs more memory and intensive computational resources. In this paper, we propose a multiresolution feature coding (MFC) framework via aggregating feature codings obtained from a set of small visual vocabularies with different sizes, where each vocabulary is obtained by a clustering algorithm, and different clustering algorithm discovers different aspect of image features. In MFC, feature codings from different visual vocabularies are aggregated adaptively by a modified Online Passive-Aggressive Algorithm under the histogram intersection kernel, which lead to a closed-form solution. Experiments demonstrate that the proposed method (1) obtains the same if not higher classification accuracy than the BoW model with a large visual vocabulary; and (2) needs much less memory and computational resources.
Combinatorial Various Classification Proceedings for Hyper spectral Evidence Awareness

In land cover classification, Hyperspectral image investigation have been used in the field of remote sensing. Hyperspectral means hundreds of bands In this classification of hyperspectral we aim to produce a thematic map is more accurate by combinatorial classification methods. A hyperspectral data is a raw data which was undetermined. The feature representation is based on two learning algorithms (Support Vector Machine (SVM) and Artificial Neural Network (ANN)) were used to perform the combination function. In this work the main aim to produce the thematic map for survey analysis which is easy to the employee can work anywhere at any time. In this method the genetic algorithm(GA) is also used to produce more accuracy in thematic map. Here the dotnet painting tool is used for color representation. Our proposal was able to reduce the time complexity, no need for assigning weights and overcome the difficulties of the usual combination rules.
The Effects of Cognitive Modification and Informed Teachers on Communication Apprehension in Children.

This study investigated the effects of two treatment conditionscognitive modification and informed teacherson communication apprehension in children in grades 4, 5 and 6. The sublects were 109 students who scored one standard deviation cr hi ar above the mean for their grade level on the Measure of E. ntary Communication Apprehension (MECA). The students were ask.4ned to one of three treataent conditions: (1) control: (2) informed teacher (in which the teacher was given a written explanation of communication anxiety (CA), was notified which of his or her students were high in CA: and was given written suggestions for dealing with CA in the classroome and (3) cognitive modification (an approach cosbining systematic desensitization and cognitive restructuring). The cognitive modification treatment sessions consisted of-ten 45-sinute sessions over a period of five weeks. The ! SECA was used as a post treataent aeasure of failed. These results indicate a relation between how children organize or tests indicated that cognitive modification significantly reduced cossunication apprehension, while inforsed teachers did not. Grade level and interaction effects were not significant. Both teachers and students found the time spent in the CM classes worthwhile. Results suggest that removing students from regular classroom activities to participate in a CM class can be justified to parents, teachers, and adsinistrators.

New Methods for Ranking Influence in Social Networks

In this work, propagation dynamics on social networks are studied in order to identify the most influential users. For this purpose, diffusion data has been collected during 4 weeks from a microblogging OSN (online social network) called Tumblr. Then, the propagation graph has been built and studied using the first 2 weeks data (period $T_1$). Subsequently, this graph has been used to predict th influencers during the last 2 weeks (period $T_2$ ). A ranking of influential nodes is obtained for $T_2$ , set as the ground truth. The aim is to predict this ranking using the data from $T_1$. Based on the average spread of users’ posts, rankings obtained with several techniques are tested and compared. These techniques include classical centrality measures used in the literature, the $T_1$ ranking itself, and new alternatives based on effective degree using local (network) information. Whilst all methods perform similarly when considering whole global ranking, differences among them appear when ranking the top influencers. For those, in general, the methods proposed here outperform the classical centrality measures.
Noise modeling in a signal conditioning circuit for low power audio application using resistive sensor

Piezoresistive sensors convert a physical value into a resistance variation. Often four resistive elements are connected together in a Wheatstone bridge to provide electrical variations of sensors. When this structure is biased with a fixed voltage source or a current source the topology provides a differential output voltage. To exploit information a conditioning circuit is associated to the bridge. In most cases it consists of an instrumentation amplifier followed by a data converter to obtain very quickly a digital representation of information. Due to the high input impedance of the instrumentation amplifier, bridge sensitivity is preserved. A filter may be added to avoid aliasing or a continuous time sigma-delta modulator that includes filtering feature. This study is concerning the conditioning structure for piezoresistive sensors bridge especially fully integrated microphones for biomedical application. The bridge signal to noise ratio is set by biasing the amplifier stage by current. The noise performance becomes the limiting factor of the read-out circuit. Current mode topologies drive amplifiers design where inputs are the main noise contributor. Modeling noise contribution is a key point in the design of the conditioning circuit. The current consumption leads noise performances too. A proposed architecture was implemented in a 65nm CMOS standard technology for performance measurement and evaluation with nanowire based microphone dedicated to hearing aids application.

C O ] 1 4 A ug 2 01 8 Monochromatic balanced components , matchings , and paths in multicolored complete bipartite graphs

It is well-known that in every r-coloring of the edges of the complete bipartite graph Kn,n there is a monochromatic connected component with at least 2n r vertices. It would be interesting to know whether we can additionally require that this large component be balanced; that is, is it true that in every r-coloring of Kn,n there is a monochromatic component that meets both sides in at least n/r vertices? Over forty years ago, Gyárfás and Lehel [12] and independently Faudree and Schelp [7] proved that any 2-colored Kn,n contains a monochromatic Pn. Very recently, Bucić, Letzter and Sudakov [4] proved that every 3-colored Kn,n contains a monochromatic connected matching (a matching whose edges are in the same connected component) of size ⌈n/3⌉. So the answer is strongly “yes” for 1 ≤ r ≤ 3. We provide a short proof of (a non-symmetric version of) the original question for 1 ≤ r ≤ 3; that is, every r-coloring of Km,n has a monochromatic component that meets each side in a 1/r proportion of its part size. Then, somewhat surprisingly, we show that the answer to the question is “no” for all r ≥ 4. For instance, there are 4-colorings of Kn,n where the largest balanced monochromatic component has n/5 vertices in both partite classes (instead of n/4). Our constructions are based on lower bounds for the r-color bipartite Ramsey number of P4, denoted f(r), which is the smallest integer l such that Department of Mathematics, Miami University, Oxford, Ohio. debiasld@miamioh.edu, kruegera@miamioh.edu Research supported in part by Simons Foundation Collaboration Grant #283194 Alfréd Rényi Institute of Mathematics, Hungarian Academy of Sciences, Budapest, P.O.
