Currency Exchange in an Open-Economy Random Search Model
Authors: Tanaka Mariko 
Published: June 2015

AbstractThis paper studies how endogenous currency exchange arises in a two-country, two-currency monetary search model. Although currency exchange is widely observed in the globalized economy, Zhou (1997) is one of the exceptional studies that adopted a search model to generate currency exchange endogenously. Moreover, in her model, currency exchange occurs only in the case where agents rarely consume foreign goods, which is contrary to the well-known fact that international trade increases the number of currency exchanges. We construct a monetary search model that has a feature that increased international trade increases the volume of currency exchange. We develop a two-country model in which each country has two types of agents: local traders who consume only the goods produced in the home country, and international traders who consume only the goods produced in the foreign country. For international traders, the foreign currency gives more opportunity to obtain the foreign goods than the home currency does. Thus, when an international trader holds the home currency, he has an incentive to exchange the home currency for the foreign currency. Unlike Zhou, the model has a feature that currency exchange is more likely to occur when many agents are engaged in international trade.
Mutation of the conserved GRG motif and
decreasing activity of human RNase H2
Authors: Li Lin , Shen Wanxiang , Zheng Jing , Lai Raofang , Tan Chunyan , Tan Ying , Jiang Yuyang 
Published: June 2015

Abstract
RNase H2 consists of three subunits (H2A, H2B
and H2C) and is involved in the hydrolysis of RNA/DNA
hybrids. The GRG motif in RNase H2 is highly conserved
and recognizes the ribonucleotides misincorporated into
dsDNA. The mutant G37S in the GRG motif of human RNase
H2A was found to be correlated with Aicardi-Goutièressyndrome
(AGS). In this study, 4 mutants (G37S, G37A,
R38A and G39A) were prepared and their biochemical
properties of secondary structure, activity and binding
affinity with substrate were studied in order to explore the
function of the GRG motif. The activity assay showed that
the mutations resulted in significantly decreased RNase
activity. The binding efficiency assay demonstrated that
binding affinities between 4 mutants and 1-ribo FAMlabeled
substrate were significantly weakened. These
results all indicated that the GRG motif contributes
directly to substrate binding and is closely related to the
enzyme activity.
Piketty’s Capital, His Critics and Basic Income
Authors: Lo Vuolo Rubén M. 
Published: June 2015

AbstractAmong other merits, Piketty’s book puts the topic of inequality and income/wealth concentration in the public agenda. His analysis concludes that aggregate income and wealth have tended to concentrate in the top few percentiles of the population. His research as well as the policy and political debate it has brought about, is relevant for the progress of the Basic Income movement. The tendencies for income and wealth concentration, the importance of inheritance for inequality, the weak foundations of current welfare state institutions, and the relevance of the tax structures for redistribution, all are central themes on the Basic Income debate. In this article, the author discusses certain aspects of Piketty’s

Published: June 2015

Abstract
Amyotrophic lateral sclerosis (ALS) is a common disease among neurological disorders that can change the pattern of gait in human. One of the effective methods for recognition and analysis of gait patterns in ALS patients is utilizing stride interval time series. With proper preprocessing for removing unwanted artifacts from the raw stride interval times and then extracting meaningful features from these data, the factorial hidden Markov model (FHMM) was used to distinguish ALS patients from healthy subjects. The results of classification accuracy evaluated using the leave-one-out (LOO) cross-validation algorithm showed that the FHMM method provides better recognition of ALS and healthy subjects compared to standard HMM. Moreover, comparing our method with a state-of-the art method named least square support vector machine (LS-SVM) showed the efficiency of the FHMM in distinguishing ALS subjects from healthy ones.
Specific emitter identification based on graphical representation of the distribution of radar signal parameters
Authors: Dudczyk J. , Kawalec A. 
Published: June 2015

Abstract
The article presents some possibilities of same type radar copies identification with the use of graphical representation. The procedure described by the authors is based on transformation and analysis of basic parameters distribution which are measured by the radar signal especially Pulse Repetition Interval. A radar intercept receiver passively collects incoming pulse samples from a number of unknown emitters. Information such as Pulse Repetition Interval, Angle of Arrival, Pulse Width, Radio Frequency and Doppler shifts are not usable. The most important objectives are to determine the number of emitters present and classify incoming pulses according to emitters. To classify radar emitters and precisely identification the copy of the same type of an emitter source in surrounding environment, we need to explore the detailed structure i.e. intra-pulse information, unintentional radiated electromagnetic emission and fractal features of a radar signal. An emitter has its own signal structure. This part of radar signal analysis is called Specific Emitter Identification. Utilization of some specific properties of electronic devices can cause heightening probability of a correct identification
Metallization of ceramic materials based on the kinetic energy of detonation waves
Authors: Chmielewski T. , Golański D. , Włosiński W. 
Published: June 2015

Abstract
The paper presents an innovatory low-energy detonation-spraying method suitable for the metallization of ceramic materials, in which the energy necessary for joining the metallic coating with the ceramic is delivered in a mechanical way. In the proposed method, the metallic particles, shot from the spraying gun, impinge onto the ceramic substrate with a high velocity, and their kinetic energy is transformed into heat delivered in a specified portion directly to the region of the metal/ceramic joint being formed. The stress distribution and the temperature field at the coating/substrate interface were analyzed also numerically with the aim to optimize the metallization process parameters so as to stimulate the formation of the coating/ceramic joint and, at the same time, to control the region of heat dissipation, the temperature, and the stress state induced in the joint

Authors: Küçükrendeci I. 
Published: June 2015

Abstract
In the study, the mechanical and microstructural properties of friction stir welded EN AW-6060 Aluminum Alloy plates were investigated. The friction stir welding (FSW) was conducted at tool rotational speeds of 900, 1250, and 1500 rpm and at welding speeds of 100, 150 and 180 mm/min. The effect of the tool rotational and welding speeds such properties was studied. The mechanical properties of the joints were evaluated by means of micro-hardness (HV) and tensile tests at room temperature. The tensile properties of the friction stir welded tensile specimens depend significantly on both the tool rotational and welding speeds. The microstructural evolution of the weld zone was analysed by optical observations of the weld zones
Safe rebuilding of the periodontal loss an experimental study
Authors: Minch L.E. , Slowinski J.J. , Scigala K. , Bedzinski R. , Kawala B. 
Published: June 2015

Abstract
This study aimed at the simulation of bone tissue remodeling within a bone defect with the utilization of the finite element method (FEM), enabling - via elaborated application - objective evaluation of orthodontic forces which positively influence periodontium in vivo. The initial position of each bracket on the passive archwire was registered, and then a geometrical and discretemodel of the appliance was created automatically. Assessment of the dental scans obtained using cone beam computed tomography (CBCT) allowed evaluation of the range of bracket displacement: from the initial position to the final one achieved on the active archwire. Those displacements established terminal conditions in the finite element analysis, enabling calculation of orthodontic force levels. An individual design of a tooth with periodontal ligaments and the periodontal defect subsequently loaded with the determined forces allowed simulation of bone remodeling according to Carters adaptation process. Mainly, the bone apposition processes took place in the central part of the periodontal defect, in proximity of the alveolar ridge. However, FEM application in the analysis of bone tissue regeneration within bone defects enables precise evaluation of the achieved changes, therefore allows determination of orthodontic forces positively influencing periodontium in vivo

Authors: Sendyka B. , Mitianiec W. , Noga M. 
Published: June 2015

Abstract
The paper presents the study of combustion process of a homogenous lean propane-air mixture in the cylindrical combustion chamber ignited by a hot gas jet from the pre-ignition chamber. A rich propane-air mixture in the pre-chamber is ignited by the spark plug and the exhaust gasses flow from the chamber trough the holes in the wall. The mathematical model of gas exchange and energy balance in chambers with a laminar finite-rate model taking into account the two-step Arrhenius chemical kinetics is presented. The work presents results of thermodynamic parameters of the charge obtained in CFD simulations in Fluent and Kiva3v for three configurations: with one hole in the wall of the ignition chamber, with three holes and without an ignition chamber. Modelling and simulation have shown faster burning of the mixture for jet ignition with three holes of the pre-chamber. The results of simulations were verified by experimental studies in the combustion chamber of the same geometry by the Schlieren method. The work presents flame front propagation, pressure traces and pressure increment speed for two mixtures with a different equivalence fuel-air ratio. Experimental results proved the simulation observation of faster flame propagation in the main chamber with three holes

Published: June 2015

Abstract
In the present scenario internet usage and the online banking sectors are experiencing spectacular growth. The Internet is the fastest growing banking channel today, both in the fields of corporate and retail banking. Banks prefer their customers to use the online banking facility as it reduces their cost, primarily through labour costs. The online banking system addresses several emerging trends: customers’ demand for anytime, anywhere service, product time-to-market imperatives and increasingly complex back-office integration challenges. Online fraud has become major source of revenue for criminals all over the globe. The challenges that oppose online banking are the concerns of security and privacy of information. This has made detecting and preventing these activities a top priority for every major bank. The use of single-factor authentication, such as a user name and the password, has been inadequate for guarding against account fraud and identity theft, in sensitive online banking systems. In this paper we are going to analyze the QKD multifactor authentication in online banking systems

The proposed method is discussed with regard to the design of optical transmitter for laser shooting simulator, however the developed methodology can be used for a number of other light shaping applications
The natural gas industry: equipment, materials, and corrosion
Authors: Valdez Benjamin , Schorr Michael , Bastidas Jose M. 
Published: June 2015

AbstractCorrosion is a crucial worldwide problem that strongly affects the oil and gas industry. Natural gas (NG) is a source of energy used in industrial, residential, commercial, and electric applications. The abundance of NG in many countries augurs a profitable situation for the vast energy industry. NG is considered friendlier to the environment and has lesser greenhouse gas emissions compared with other fossil fuels. In the last years, shale gas is increasingly exploited in the USA and in Europe, using a hydraulic fracturing (fracking) technique for releasing gas from the bedrock by injection of saline water, acidic chemicals, and sand to the wells. Various critical sectors of the NG industry infrastructure suffer from several types of corrosion: steel casings of production wells and their drilling equipment, gas-conveying pipelines including pumps and valves, plants for regasification of liquefied NG, and municipal networks of NG distribution to the consumers. Practical technologies that minimize or prevent corrosion include selection of corrosion-resistant engineering materials, cathodic protection, use of corrosion inhibitors, and application of external and internal paints, coatings, and linings. Typical cases of corrosion management in the NG industry are presented based on the authors’ experience and knowledge.

Published: June 2015

Abstract

Objective: To study the clinical outcome of fetal ovarian cysts managed with in utero aspiration.

Methods: All cases of fetal ovarian cysts diagnosed from 2002 to 2013 were reviewed. In utero aspiration was performed for patients with simple cysts larger than 4 cm before term gestation.

Results: There were 21 cases of fetal ovarian cysts. Four patients (19%) were diagnosed with complex cysts at the time of referral. Among the 17 cases of simple cysts, in utero aspiration was performed in seven patients. There were no complications after the therapy and none of them developed complex cysts. An ovarian cyst was confirmed by cyst fluid that contained high levels of estradiol, progesterone and testosterone. For two patients with simple cysts who met the indications for in utero aspiration but did not receive therapy, one developed a complex cyst. Among the eight patients with simple cysts who did not fulfill the indications for aspiration, seven of them had cysts that regressed spontaneously, and one developed complex cysts during pregnancy.

Conclusion: Torsion of fetal ovarian cysts was common with expectant management. Management of fetal ovarian cysts larger than 4 cm using in utero aspiration may avoid torsion, which could otherwise lead to ovarian loss.
Choosing among the Shades of Nuance: The Discourse of Proportionality in International Law
Authors: Vaypan Grigory 
Published: June 2015

AbstractProportionality has been largely misunderstood both by its proponents and by its critics. On the one hand, it has been wrongly regarded as a more transparent and at the same time a more controllable alternative to other types of legal discourses. On the other hand, it has been incorrectly viewed as a realm of unlimited subjectivity and pure politics. In fact, proportionality oscillates between law and politics, trying to reconcile the two yet constantly falling into one or another. The article studies the dialectical structure of proportionality and explores proportionality as an argumentative practice.
The role of Society for Adolescent Health and Medicine in training of health professionals
Authors: Ford Carol A. 
Published: June 2015

Abstract
The Society for Adolescent Health and Medicine (SAHM) was created by health professionals committed to identifying and better addressing the health needs of adolescents and young adults, and this work has continued for nearly 50 years. The society initially focused primarily on clinical education, but has evolved to include educational activities providing clinical, research, policy, advocacy, and professional development content. Strategies have included high-quality annual meetings designed to meet the educational needs of its multi-disciplinary membership, publishing an internationally recognized journal, and developing strategic collaborations to advocate for legitimacy of the field and reform in health profession education. Historically, SAHM has been most successful at increasing specialized training in the United States among physicians, and primarily pediatricians, likely driven by the nuances of the development of adolescent medicine in this country. Successes are often linked to strategic collaborations with other professional organizations, and have been facilitated by federally funded initiatives to improve adolescent and young adult health. Recent efforts to improve professional training are focused on the use of technology, and SAHM is also currently exploring strategies to directly reach adolescents, young adults, and their parents. As the society becomes increasingly multidisciplinary and international, members have extraordinary opportunities to learn from each other, build upon lessons learned, and collaborate. Descriptions of the history of SAHM’s training-focused efforts, selected highlights, and current priorities will be used to illustrate this long-standing commitment to the training of health professionals.
Analysis, Design and Experimental Validation of Modified Simple Soft Switching DC-DC Boost Converter
Authors: Raghavendran S. , Babu B. Chitti , Piegari Luigi 
Published: June 2015

Abstract
This paper investigates a modified simple soft switching dc-dc converter for low power applications. This simple topology uses an auxiliary switch, an inductor and a capacitor to operate the converter without switching losses. The efficiency of the converter is improved by transferring the energy that would be dissipated during the switching to the load. The main switch turns-on with zero current switching (ZCS) and turns-off with zero voltage switching (ZVS), while the auxiliary switch turns-on and turns-off with zero voltage switching (ZVS). The detailed theoretical analysis and the design equations are described. In addition to that, the analysis of proposed converter is demonstrated by both simulation and experimental results for effectiveness of the study.

Abstract
Thermally activated delayed fluorescence (TADF) emitters are third-generation electroluminescent materials that realize highly efficient organic light-emitting diodes (OLEDs) without using rare metals. Here, after briefly reviewing the principles of TADF and its use in OLEDs, we report a sky-blue TADF emitter, 9-(4-(benzo[d]thiazol-2-yl)phenyl)-N

6-tetraphenyl-9H-carbazole-3,6-diamine (DAC-BTZ). DAC-BTZ is a purely organic donor–acceptor-type molecule with a small energy difference between its lowest excited singlet state and lowest triplet state of 0.18–0.22 eV according to fluorescence and phosphorescence spectra of a DAC-BTZ-doped film. In addition, the doped film exhibits a high photoluminescence quantum yield of 0.82. Time-resolved photoluminescence measurements of the doped film confirm that DAC-BTZ emits TADF. An OLED containing DAC-BTZ as an emitter exhibits a maximum external quantum efficiency (EQE) of 10.3%, which exceeds those obtained with conventional fluorescent emitters (5–7.5%). TADF from DAC-BTZ makes a large contribution to the high EQE of its OLED.
Crustal and upper mantle seismic structure of the Svalbard Archipelago from the receiver function analysis
Authors: Wilde−Piórko Monika 
Published: June 2015

AbstractReceiver function provides the signature of sharp seismic discontinuities and the information about the shear wave (S−wave) velocity distribution beneath the seismic station. This information is very valuable in areas where any or few reflection and/or refraction studies are available and global and/or regional models give only rough information about the seismic velocities. The data recorded by broadband seismic stations have been analysed to investigate the crustal and upper mantle structure of the Svalbard Archipelago. Svalbard Archipelago is a group of islands located in Arctic, at the north−western part of the Barents Sea continental platform, which is bordered to the west and to the north by passive continental margins. The new procedure of parameterization and selection of receiver functions (RFs) has been proposed. The back−azimuthal sections of RF show a strong variation for the HSPB and KBS stations. Significant amplitudes of transversal component of RF (T−RF) for the HSPB station indicate a shallow dipping layer towards the southwest. The structure of the crust beneath the SPITS array seems to be less heterogeneous, with very low amplitudes of converted phase comparing to the KBS and HSPB stations. Forward modelling by trial−and−error method shows a division of the crust into 3-4 layers beneath all stations and layering of the uppermost mantle beneath the SPITS array and the HSPB stations. The thickness of the mantle transition zone is larger for western part of archipelago and smaller for eastern part comparing to iasp91 model.
