Published: October 2017

Aim: The aim of this study was to evaluate electrocardiographic characteristics associated with in-hospital prognosis in patients with left main acute coronary syndrome. Methods and results: A total of 89 left main acute coronary syndrome subjects were selected from 3357 consecutive acute coronary syndrome patients (2.7%). Patients of this study were divided into two groups; those who survived and those who died. Patients’ characteristics and electrocardiogram on admission were then retrospectively analyzed between the two groups. In-hospital mortality was 28.1%. The prevalence and degree of ST-segment elevation at lead aVL were significantly higher in the deceased group than in the survival group ( p<0.001). However, those at lead aVR did not show significant differences between the two groups. Moreover, the width of the QRS-complex was significantly wider (lead V3; p<0.001), and the level of five minus the absolute value of five minus number of ST-segment elevation (5–|5–ST|; due to the highest in-hospital mortality (70%) in the five-lead ST-segment elevation group) was significantly larger in the deceased group than in the survival group ( p<0.001). The odds ratios that predicted in-hospital cardiac death were 1.03 for width of the QRS-complex at lead V3 (95% confidence interval (CI); 1.01–1.06; p=0.003), 1.74 for 5–|5–ST| (95% CI; 1.03–3.00; p=0.040), and 1.44 for ST-segment elevation at lead aVL (95% CI; 0.93–2.23; p=0.100). Conclusions: ST-segment elevation at lead aVL rather than aVR, width of the QRS-complex at lead V3 and number of ST-segment elevation were the prognostic predictors for in-hospital mortality in patients with left main acute coronary syndrome. Electrocardiographic characteristics should be assessed in addition to the established risk score in patients with left main acute coronary syndrome.

Published: October 2017

Purpose: Histological architecture of normal acetabular labrum regarding free nerve endings (FNEs) and mechanoreceptors (MRs) has been satisfactorily described in the literature. However, the presence of FNEs and MRs in acetabular labrum of hip joint has been analyzed only once in patients with osteoarthritis (OA). Aim of this article is to report histological distribution pattern of FNEs and MRs in acetabular labrum of patients with severe OA, at the same time conducting a comparison with normal acetabular labrum described in the literature. Methods: Seven patients with severe hip OA were enrolled in this study. Patient selection was assisted by the utilization of specific clinical scales delineated by the American College of Rheumatology. After successful total hip arthroplasty, tissue samples of acetabular labra of seven patients were histologically processed and stained with the gold standard chloride method, which was subsequently examined under a compound microscope. Results: FNEs and MRs constituted the major histological structures. Identified MRs included Pacini corpuscles, Ruffini corpuscles, and Golgi-Mazzoni corpuscles. The presence of FNEs was predominant in the middle part of the acetabular labrum, featuring a remarkable decrease in peripheral parts. In contrast, MRs were detected basically in peripheral parts and less in the middle part. Conclusions: Differentiation of the distribution pattern of MRs and FNEs in acetabular labrum of hip joint is remarkable between normal patients and patients with severe OA. The abundance of FNEs in the middle part of the pathologic labrum is mainly responsible for the observed discrimination. A “conversion” of MRs to FNEs may occur during OA progression, modulating therefore this pattern as well as the upcoming clinical manifestations.
FCR achieves long-term durable remissions in patients with IGHV-mutated CLL
Authors: Chai-Adisaksopha Chatree , Brown Jennifer R. 
Published: October 2017

Abstract
In chronic lymphocytic leukemia (CLL) patients with mutated IGHV, 3 recent studies have demonstrated prolonged progression-free survival (PFS) after treatment with fludarabine-cyclophosphamide-rituximab (FCR) chemoimmunotherapy. We performed a systematic review to assess the benefit of FCR for patients with CLL and identified 5 randomized trials that met our inclusion criteria. FCR improved complete remission, PFS and overall survival vs the comparator; median PFS was not reached in the subgroup of CLL patients with mutated IGHV.
International terrorism as an instrument of political struggle and of injury to integrational law
Authors: Lessa Pablo Henrique Cordeiro , Martini Sandra Regina 
Published: October 2017

AbstractInternational Terrorism happens since old ages, when it was classified as acts against the monarch. Only in modern age, it was classified as political crime committed against the State. However, despite the occurrence since ancient times, the topic gained practice importance in the International Agenda only after the international repercussion of September 11th. At this time, many researches described the political aspect of it, disregarding the economic scenario, especially considering the State interventionism that is taken to avoid economic chaos. Indeed, the State function is also discussed in order to understand how it may keep Social Welfare. This practice instils in collective perspective the association of terrorism with specific ethnic and religious groups, indirectly supporting a nationalist mentality that tends to be exploited by populist governments. This creates a bad view over resistant movements, in which are included the Third World Countries Movements, such as TWAIL, that contests the international balance of power.
Capitalism as Nineteenth-Century Colonialism and Its Impacts on Native Californians
Authors: Sunseri Charlotte K. 
Published: October 2017

AbstractThis article analyzes the impact of colonialism on nineteenth-century Native California communities, particularly during the American annexation of the West and capitalist ventures in mining and milling towns. Using the case study of Mono Lake Kutzadika Paiute employed by the Bodie and Benton Railroad and Lumber Company at Mono Mills, the lasting legacies of colonialism and its impacts on contemporary struggles for self-determination are explored. The study highlights the role of capitalism as a potent form of colonialism and its enduring effects on tribes’ ability to meet federal acknowledgment standards. This approach contributes to a richer understanding of colonial processes and their impacts on indigenous communities both historically and today.
The Arf GEF GBF1 and Arf4 synergize with the sensory receptor cargo, rhodopsin, to regulate ciliary membrane trafficking
Authors: Wang Jing , Fresquez Theresa , Kandachar Vasundhara , Deretic Dusanka 
Published: October 2017

ABSTRACT
The small GTPase Arf4 and the Arf GTPase-activating protein (GAP) ASAP1 cooperatively sequester sensory receptor cargo into transport carriers targeted to primary cilia, but the input that drives Arf4 activation in this process remains unknown. Here, we show, by using frog retinas and recombinant human proteins, that during the carrier biogenesis from the photoreceptor Golgi/trans-Golgi network (TGN) a functional complex is formed between Arf4, the Arf guanine nucleotide exchange factor (GEF) GBF1 and the light-sensing receptor, rhodopsin. Rhodopsin and Arf4 bind the regulatory N-terminal dimerization and cyclophillin-binding (DCB)-homology upstream of Sec7 (HUS) domain of GBF1. The complex is sensitive to Golgicide A (GCA), a selective inhibitor of GBF1 that accordingly blocks rhodopsin delivery to the cilia, without disrupting the photoreceptor Golgi. The emergence of newly synthesized rhodopsin in the endomembrane system is essential for GBF1-Arf4 complex formation in vivo. Notably, GBF1 interacts with the Arf GAP ASAP1 in a GCA-resistant manner. Our findings indicate that converging signals on GBF1 from the influx of cargo into the Golgi/TGN and the feedback from Arf4, combined with input from ASAP1, control Arf4 activation during sensory membrane trafficking to primary cilia.

Financial Integration and Liquidity Crises
Authors: Castiglionesi Fabio , Feriozzi Fabio , Lorenzoni Guido 
Published: October 2017

This paper analyzes the effects of financial integration on the stability of the banking system. Financial integration allows banks in different regions to smooth local liquidity shocks by borrowing and lending on a world interbank market. We show under which conditions financial integration induces banks to reduce their liquidity holdings and to shift their portfolios toward more profitable but less liquid investments. Integration helps reallocate liquidity when different banks are hit by uncorrelated shocks. However, when a correlated (systemic) shock hits, the total liquid resources in the banking system are lower than in autarky. Therefore, financial integration leads to more stable interbank interest rates in normal times but to larger interest rate spikes in crises. These results hold in a setup in which financial integration is welfare improving from an ex ante point of view. We also look at the model’s implications for financial regulation and show that, in a second-best world, financial integration can increase the welfare benefits of liquidity requirements.

The Value of Multidimensional Rating Systems: Evidence from a Natural Experiment and Randomized Experiments
Authors: Chen Pei-Yu , Hong Yili , Liu Ying 
Published: October 2017

Online product ratings offer information on product quality. Scholars have recently proposed the potential of designing multidimensional rating systems to better convey information on multiple dimensions of products. This study investigates whether and how multidimensional rating systems affect consumer satisfaction (measured by product ratings), based on both observational data and two randomized experiments. Our identification strategy of the observational study hinges on a natural experiment on TripAdvisor when the website started to allow consumers to rate multiple dimensions of the restaurants, as opposed to only providing an overall rating, in January 2009. We further obtain rating data on the same set of restaurants from Yelp, which controls for the unobserved restaurant quality over time and allows us to identify the causal effect using a difference-in-differences approach. Results from the econometric analyses show that ratings in a single-dimensional rating system have a downward trend and a higher dispersion, whereas ratings in a multidimensional rating system are significantly higher and convergent. Findings from two randomized experiments suggest that the multidimensional rating system helps consumers find products that better fit their preferences and increases the confidence of their choices. We also show that the observed results cannot be explained by the priming effect due to rating system interface or a list of other alternative explanations. The combined evidence from the natural experiment and randomized experiments support the view that the multidimensional rating system enhances rating informativeness and provide implications for designing online rating systems that help consumers match their preferences with product attributes.

A Bayesian Pricing of Longevity Derivatives with Interest Rate Risks
Authors: Kogure Atsuyuki , Fushimi Takahiro 
Published: October 2017

AbstractMortality-linked securities such as longevity bonds or longevity swaps usually depend on not only mortality risk but also interest rate risk. However, in the existing pricing methodologies, it is often the case that only the mortality risk is modeled to change in a stochastic manner and the interest rate is kept fixed at a pre-specified level. In order to develop large and liquid longevity markets, it is essential to incorporate the interest rate risk into pricing mortality-linked securities. In this paper we tackle the issue by considering the pricing of longevity derivatives under stochastic interest rates following the CIR model. As for the mortality modeling, we use a two-factor extension of the Lee-Carter model by noting the recent studies which point out the inconsistencies of the original Lee-Carter model with observed mortality rates due to its single factor structure. To address the issue of parameter uncertainty, we propose using a Bayesian methodology both to estimate the models and to price longevity derivatives in line with (Kogure, A., and Y. Kurachi. 2010. “A Bayesian Approach to Pricing Longevity Risk Based on Risk Neutral Predictive Distributions.”Insurance: Mathematics and Economics46:162–172) and (Kogure, A., J. Li, and S. Y. Kamiya. 2014. “A Bayesian Multivariate Risk-neutral Method for Pricing Reverse Mortgages.”North American Actuarial Journal18:242–257). We investigate the actual effects of the incorporation of the interest rate risk by applying our methodology to price a longevity cap with Japanese data. The results show significant differences according to whether the CIR model is used or the interest rate is kept fixed.
Wer hat den Dyotheletismus erfunden?
Authors: Ohme Heinz 
Published: October 2017

AbstractThis article examins the hypothesis published in 2013 by Marek Jankowiak, according to which Pope John IV in his so-called Apologia Honorii (CPL 1729) and Maximos Homologetes independently “invented” a dyotheletic Christology for the first time. For that purpose, this letter by John IV is analysed with regard to its sources, its text and the context of its composition. It is shown that the letter, which is preserved only in a Latin retranslation from Greek by Anastasius Bibliothecarius made in 874/75, originally referred only the monothelistic statement of Pope Honorius to the human nature of Christ. The dyotheletic statements, which can also be found in the text, are the result of later updating. This updating begins already in the 7th century in the circle of Maximos’ followers. Here, as well as in the context of the oldest tradition at Anastasius Biliothecarius in the so-called Photian Schism, the conflict-oriented interest in an unlimited authority of the papacy stands in the background. The “invention” of the theologoumenon of a double will in Christ should be assigned exclusively to Maximos Homologetes.

Symbolic Algorithm of the Functional-Discrete Method for a Sturm–Liouville Problem with a Polynomial Potential
Authors: Makarov Volodymyr , Romaniuk Nataliia 
Published: October 2017

Abstract
A new symbolic algorithmic implementation of the general scheme of the exponentially convergent functional-discrete method is developed and justified for the Sturm–Liouville problem on a finite interval for the Schrödinger equation with a polynomial potential and the boundary conditions of Dirichlet type. The algorithm of the general scheme of our method is developed when the potential function is approximated by the piecewise-constant function. Our algorithm is symbolic and operates with the decomposition coefficients of the eigenfunction corrections in some basis.
The number of summands in these decompositions depends on the degree of the potential polynomial and on the correction number.
Our method uses the algebraic operations only and does not need solutions of any boundary value problems and computations of any integrals unlike the previous version.
A numerical example illustrates the theoretical results.
Analysis of the Steady-State Multiplicity Behavior for Polystyrene Production in the CSTR
Authors: Nguyen Sang Thanh , Hoang Ngoc Ha , Hussain Mohamed Azlan 
Published: October 2017

Abstract
The work proposes two different approaches where the first one is based on the tools of the system theory and the other is strongly related to the principle of heat balance, in order to analyze the abnormal phenomena of the continuous styrene polymerization reactors, i. e. the multiplicity behavior in the wide range of operating conditions. More precisely, the multiplicity behavior of polystyrene production in a continuous stirred tank reactor (CSTR) is carried out by the numerical simulations through the Van Heerden diagram and the phase plane. Furthermore, the bifurcation diagrams in terms of two different inputs including jacket temperature and volumetric flow rate of initiator predict the appearance of multiplicity behavior as well as the saddle-node bifurcation points. The results, firstly, verify that the multiplicity behavior of the system appears under considered operating conditions. Secondly, the analysis of bifurcation behavior gives the theoretical prediction of multiplicity behavior once the operating conditions vary due to the soft constraints or the effect of noise and disturbance.
Lower bound for the complexity of five-valued polarized polynomials
Authors: Baliuk Aleksandr S. , Zinchenko Anna S. 
Published: October 2017

Abstract
The paper is devoted to the complexity of representation of q-valued functions by polarized polynomials and by matrix Kronecker forms of certain type. The complexity of a function is the minimal possible number of nonzero coefficients of a polynomial or a Kronecker form representing the function. It is known that for polynomial representation and representation by Kronecker forms of a certain type the maximal values of complexity in the class of all q-valued n-ary functions coincide. We establish the lower bound of these maximal values for five-valued functions.
Example of sewerage system rehabilitation using trenchless technology
Authors: Tomczak Elwira , Zielińska Aleksandra 
Published: October 2017

Abstract
The sewerage network in Poland, built in the early 20th century, has been losing its original water-tightness and flow capacity. To bring these characteristics back, rehabilitation works are performed. The initial capacity of sewers can be restored without affecting the urban environment thanks to the trenchless technology. The sewer subjected to rehabilitation receives a new internal leakproof layer capable of preventing groundwater infiltration as well as sewage leaks, which can contaminate the environment. This paper intends to compare the trenchless technology with traditional open cut trench excavation. In the study, two variants of trenchless rehabilitation were considered: one performed with the help of GRP panels and the other using cured-in-place pipe (CIPP) lining. Flow velocities and flow rates in the sewers before and after rehabilitation were compared. Also, selected economic and environmental aspects of sewer rehabilitation methods were examined.

AbstractA novel scheme of a shrunken Wilkinson power divider with harmonic suppression, using two identical resonators in the conventional Wilkinson power divider is designed. Moreover, the LC equivalent circuit and its relevant formulas are provided. To substantiate the functionality and soundness of design, a microstrip implementation of this design operating at 1 GHz with the second to eighth harmonic suppression, is developed. The proposed circuit is relatively smaller than the conventional circuit, (roughly 55% of the conventional circuit). Simulation and measurement results for the proposed scheme, which are highly consistent with one another, indicate a good insertion loss about 3.1 dB, input return loss of 20 dB and isolation of 20 dB, while sustaining high-power handling capability over the Wilkinson power divider.
