Effect of Actual and Perceived Violence on Internal Migration: Evidence from Mexico’s Drug War
Authors: Fernandez-Dominguez Amilcar Orlian 
Published: May 2020

Abstract
According to the Organisation for Economic Co-operation and Development (OECD), violence should be considered by examining both actual and perceived crime. However, the studies related to violence and internal migration under the Mexican drug war episode focus only on one aspect of violence (perception or actual), so their conclusions rely mostly on limited evidence. This article complements previous work by examining the effects of both perceived and actual violence on interstate migration through estimation of a gravity model along three 5-year periods spanning from 2000 to 2015. Using the methods of generalized maximum entropy (to account for endogeneity) and the Blinder–Oaxaca decomposition, the results show that actual violence (measured by homicide rates) does affect migration, but perceived violence explains a greater proportion of higher average migration after 2005. Since this proportion increased after 2010 and actual violence, the results suggest that there was some adaptation to the new levels of violence in the period 2010–2015.

Published: May 2020

AbstractIn this paper, we propose a new population-based evolutionary algorithm that automatically configures the used search mechanism during its operation, which consists in choosing for each individual of the population a single evolutionary operator from the pool. The pool of operators comes from various evolutionary algorithms. With this idea, a flexible balance between exploration and exploitation of the problem domain can be achieved. The approach proposed in this paper might offer an inspirational alternative in creating evolutionary algorithms and their modifications. Moreover, different strategies for mutating those parts of individuals that encode the used search operators are also taken into account. The effectiveness of the proposed algorithm has been tested using typical benchmarks used to test evolutionary algorithms.
Spontaneous Sublingual Haematoma in a 90-year Old Patient: A Complication of Direct Oral Anticoagulants
Authors: Cnossen Johannes Daniël , Schoonderbeek Jeannette Fenna , Muller Maaike 
Published: May 2020

Abstract
Sublingual haematoma is a rare complication of anticoagulants and can be life-threatening. As the number of prescribed anticoagulants is increasing, the incidence of complications of these drugs will continue to increase. A report of a sublingual haematoma in an elderly patient with chronic atrial fibrillation treated with edoxban (Lixiana ©, Daiichi Sankyo Europe GmbH, München, Germany) is reported. A 90-year male presented at the emergency department with an obstructed upper airway due to a sublingual haematoma. The patient received tranexamic acid, prothrombin complex, and fresh frozen plasma. After fiberoptic nasal intubation, the patient was monitored in the intensive care unit. After four days, the patient was extubated, and after six days, the swelling resolved completely. Complications of anticoagulants are rare but can be life-threatening. Recognition of an endangered airway and reversing the effects of the anticoagulant are essential. Surgical evacuation of the haematoma could be considered but is not necessary.

Published: May 2020

Abstract
Congenital aortic stenosis (AS) occurs in around 0.2–0.5% of newborns, and its clinical severity is quite variable. Some of the newborns with AS require urgent medical care: prostaglandin infusion, balloon aortic valvuloplasty, or surgical intervention. Despite having a severe clinical evolution in neonates, the prenatal diagnosis of congenital AS is quite low. We present the case of a fetus with critical AS, who had been prenatally diagnosed at 35 weeks of gestation, via fetal cardiac ultra-sound. The echocardiographic parameters revealed a severely depressed left ventricular systolic function, with dilated chambers, and a severe aortic stenosis. Offline speckle-tracking analysis was performed in order to aid in deciding the optimal methods and timing of delivery. Left ventricular analysis revealed a severely impaired global longitudinal strain of 2.1%, left ventricular ejection fraction 18.4%, increased LV volumes, while the right ventricular function was only mildly depressed. Therefore, the decision was to delay the premature delivery, and the fetus was born at a gestational age of 38 weeks, in a hospital with a neonatal cardiovascular surgery department. The patient had undergone surgical repair of the cardiac anomaly at 3 days after birth.
Brugada Syndrome – Report of Familial Occurrence Diagnosed in the Emergency Department
Authors: Fazel Mojtaba , Hamidi Fatemeh , Afshari Elham 
Published: May 2020

Abstract

Introduction: Brugada syndrome represents the clinical manifestation of a rare disease with genetic etiology. The syndrome is characterized by ventricular dysrhythmias associated with syncope or sudden cardiac death in the lack of any structural cardiac disease. The diagnosis of Brugada syndrome is established if a type 1 electrocardiographic (ECG) pattern of ST-segment and QRS morphology is present, in association with certain clinical manifestations and/or familial history.

Case presentation: A 31-year-old male patient, without any medical history, presented in the emergency department (ED) of a clinical center. His only complaints consisted in palpitations, chest discomfort, and emotional stress related to the recent death of his wife. Earlier on the same day, his wife, a 25-year-old female was brought via emergency medical services (EMS) to the ED after presenting ventricular fibrillation. The female patient presented a long term history of chest pain and one year prior to this episode she presented idiopathic ventricular fibrillation, for which she had undergone implantation of an automated cardioverter defibrillator. As the couple were cousins, the EMS specialist suspected the presence of a familial cardiac disorder. The electrocardiogram of the male patient revealed a coved-type ST-segment elevation of 4 mm in leads V1–V3 compatible with type 1 Brugada syndrome.

Conclusion: In case of Brugada syndrome, a genetic disorder associated with increased risk of SCD, the patient's first-degree relatives should be investigated as well, in order to identify the presence of the syndrome and to prevent SCD. As the sole established effective therapeutic measure for patients diagnosed with Brugada syndrome, ICD implantation should be considered in order to decrease the risk of syncope and SCD. This case is particular because a rare disease with familial etiology was identified in both husband and wife, who were cousins.
Implementation of the orthodoxy test as a validity check on experimental field emission data
Authors: Allaham Mohammad M. , Forbes Richard G. , Knápek Alexandr , Mousa Marwan S. 
Published: May 2020

Abstract
In field electron emission (FE) studies, it is important to check and analyse the quality and validity of experimental current-voltage data, which is usually plotted in one of a small number of standard forms. These include the so-called Fowler-Nordheim (FN), Millikan-Lauritsen (ML) and Murphy-Good (MG) plots. The Field emission orthodoxy test is a simple quantitative test that aims to check for the reasonableness of the values of the parameter “scaled field” that can be extracted from these plots. This is done in order to establish whether characterization parameters extracted from the plot will be reliable or, alternatively, likely to be spurious. This paper summarises the theory behind the orthodoxy test, for each of the plot forms, and confirms that it is easy to apply it to the newly developed MG plot. A simple, new, accessible web application has been developed that extracts scaled-field values from any of these three plot forms, and tests for lack of field emission orthodoxy.

Published: May 2020

Abstract
We present the design of a tri-band E-shaped printed antenna with C-shaped slots. A Rectangular patch etched with an n-shaped slot is added at the back of the substrate to enhance the bandwidth and the return losses of the resonant bands - particularly, that of the second band. Our antenna is designed to operate at 1.51/2. 46/6.11 GHz. As can be observed from the experimental results, it has 10 dB bandwidths of 157 MHz (1.416 to 1.573 GHz) 358 MHz (2.221 to 2.579 GHz) and 367 MHz (5. 918 – 6. 285 GHz) The first two bands cover the LTE, Bluetooth, IEEE 802.15.4 ZigBee and IEEE 802.11 WLAN applications. The third resonant band covers the unlicensed 6 GHz band which is widely implemented in wireless power transmission, as well as, RFID and satellite communications. In order to ease wireless congestion, the 6 GHz band is also currently being considered by the FCC to be opened up for the use of WiFi applications. Our antenna is fabricated on a single-sided FR4-epoxy, and it constitutes a compact size of 34 mm × 36 mm × 1.6 mm or 0.17λ × 0.18λ times0.0081λ, (based on the 1.51 GHz lowest resonant frequency) The antenna exhibits omnidirectional radiation patterns at the three resonant bands.
Evolution of Political and Security Relationship between the Republic of Poland and the United States of America in the years 1999–2019
Authors: Kozlowski Grzegorz 
Published: May 2020

Abstract
The article discusses the evolution of political and security cooperation between the Republic of Poland and the United States of America in the years 1999–2019. It argues that this relationship has been strengthened over the past several years to an unprecedented level, as reflected by the following: (a) permanent presence of US troops and facilities on the territory of the Republic of Poland; (b) significant reinforcement of energy cooperation that would contribute to the security of the Central and Eastern European (CEE) region; (c) development of a high-level strategic dialogue; and (d) successful widening of the mutual scope of soft security collaboration, including economic, digital and people-to-people aspects. In this article, I try to answer the following questions: what are the reasons of upgrading Poland–US political and security relations? What was the process shaping US– Poland relationship during 1999–2019? What are the priorities for both sides in this cooperation? I suggest that the past 20 years of Polish–American relationship can be divided into three stages: (a) between Poland’s accession to North Atlantic Treaty Organization (NATO) and Russian aggression towards Ukraine (1999–2014); (b) between the NATO Summit in Newport and the swearing in of Donald Trump as President of the United States (2014–2017); and (c) then onwards (2017/2018–).

Published: May 2020

Abstract
The role of the human factor in aviation is a critical element for the safety of flight operations. It is described by methods such as SHELL and BowTie, which propose solutions to minimize the risk of occurrence of aviation events. The work presents the development of these concepts by introducing the method of testing the predisposition of airport staff using a specialized system which is the Polipsychograph - a system dedicated to designing and carrying out psychological tasks testing human mental, cognitive and motor skills in connection with the assessment of his professional capabilities. The work contains the results of 40 tests performed on employees dealing with airport ground handling on a daily basis. Research has shown that the employee’s predisposition depends on the quality of work entrusted to him. The paper presents a method of assessing the psychophysical predisposition of an employee allowing him to be directed to work corresponding to his qualifications.

Authors: Porco Pierluigi , Przysowa Radoslaw , Botto Daniele 
Published: May 2020

Abstract
Composite fan blades are more and more common both in aviation and ground applications. This work aims to characterize the vibration parameters of plastic blades installed in a wind tunnel fan by a non-contact method, namely blade tip timing (BTT). Blade dynamics was predicted with finite element modelling (FEM) and confirmed experimentally by tip timing measurements and analysis of data. BTT results were acquired and compared in two different configurations. A good agreement between predicted and measured frequency values was obtained for the fundamental mode. Significant differences were observed for the second and third modes due to material anisotropy and contact effects which could not be modelled because necessary material data were unavailable.

The socioeconomic performance of small and mediumsized industrial towns: Slovenian perspectives
Authors: Bole David , Kozina Jani , Tiran Jernej 
Published: May 2020

AbstractThe socioeconomic performance of industrial small and medium-sized towns (SMSTs) in comparison to that of non-industrial SMSTs, is subject to evaluation in this paper, to see if the presence of industry has adverse effects on socioeconomic factors. We studied 32 variables accounting for dimensions of socioeconomic performance in Slovenian SMSTs and conducted various statistical tests. We found only minor differences between the two groups, pertaining mainly to some elements of economic structure and demography, and some mixed relations of industrial employment and socioeconomic performance. The results demonstrate that industrial SMSTs should not be labelled automatically as ‘disadvantaged’. We discuss why our results differ from general research expectations in the literature: in the local context, we outline the “egalitarian syndrome” and policies of polycentric spatial development; in the global context, we discuss the “failed tertiarisation effect” and the differences between post-socialist and “Western” countries. We conclude by proposing that research should be re-oriented towards the more place-sensitive issues of industrial towns across Europe.
Changes in urban transport behaviours and spatial mobility resulting from the introduction of statutory Sunday retail restrictions: A case study of Lodz, Poland
Authors: Borowska-Stefańska Marta , Kowalski Michał , Wiśniewski Szymon 
Published: May 2020

Abstract
The impact of statutory Sunday retail restrictions on the transport behaviours of people living in the Polish post-socialist city of Lodz is investigated in this article. One carrier of information on journeys undertaken in the city is data from induction loops – a part of the city’s Intelligent Transportation System (ITS). The second source of data is a two-stage questionnaire survey (concerning trading and non-trading Sundays) of the city’s inhabitants, aimed at defining any changes in their transport behaviours with reference to the introduction of retail restrictions. The research was conducted to assess the way in which the new statutory restrictions affect transport behaviour discharged after the political transformation. The results of the research conducted on the transport behaviours of Lodz residents indicate that the majority of their transport behaviours clearly depend on whether a given Sunday is a trading or non-trading day. The traffic load of the urban road network (perceived as the manifestation of residents’ spatial mobility) is characterised by a distinct changeability due to the legislative restrictions related to Sunday trading. There is both a time (daily and hourly) differentiation of traffic flows and a spatial changeability of the load in the urban space, when a comparative analysis is conducted of the results of observations made in the weeks preceding trading and non-trading Sundays. The study also demonstrates that the time previously devoted to Sunday shopping is currently spent not only at home, but also allocated to new (and until now unperformed) activities that often require travelling.
Direct formation of ZnO nanorods by hydrothermal process: study on its optical properties and electron transport

Published: May 2020

Abstract
We report a new direct fabrication of the ZnO nanorods (NR) by hydrothermal method, in which the preparation of seed layer is eliminated. We show that the tuning of initial temperature rate during the hydrothermal process plays a key role in the structural modification of the ZnO NR. A highly oriented ZnO NR is successfully fabricated by using a low rate of initial temperature. The increase of optical absorption and electron transport was obtained by reducing the diameter and increasing distribution of the ZnO NR on the substrate. Interestingly, an additional absorption from the defects is obtained in the system, which plays an important role in expanding the optical absorption. Our system will provide a favourable characteristic for developing the high-performance optoelectronic devices with high optical absorption and high electron transport.

Published: May 2020

Abstract
Polyurethane (PU) is a polymer widely used in the biomedical field with excellent mechanical properties and good biocompatibility. However, it usually exhibits poor antibacterial properties for practical applications. Efforts are needed to improve the antibacterial activities of PU films for broader application prospect and added application values. In the present work, two PU films, TDI-P(E-co-T) and TDI-N-100-P(E-co-T), were prepared. Silver nanoparticles (AgNPs) were composited into the TDI-N-100-P(E-co-T) film for better mechanical properties and antibacterial activities, and resultant PU/AgNPs composite film was systematically characterized and studied. The as-prepared PU/AgNPs composite film exhibits much better antibacterial properties than the traditional PU membrane, exhibiting broader application prospect.
Free radical scavenging ability of sodium lignosulfonate and its application in food grade polypropylene
Authors: Musajian Dilhumar , Hasan Gvlmira , He Mingyu , Yimit Mamatjan 
Published: May 2020

Abstract
Sodium lignosulfonate (SL) was prepared from waste of cotton lignin (CL) through hydrothermal reaction method. Orthogonal experiment was designed with value of OIT as objective function. Polypropylene (PP) is a polymer produced by the addition polymerization of propylene. It is a white waxy material with a transparent and light appearance, which is widely used in food and pharmaceutical packaging. The results of GPC and TG analysis revealed that SL has stable thermal properties, which means that SL has the potential to be an antioxidant for PP materials. In addition, the scavenging effects of CL and SL were studied. The obtained results exhibited that the SL can obviously increase the scavenging effect on free radicals and it is a kind of new synthetic antioxidant with antioxidant property, which could effectively delay the oxidation of PP. Subsequent rheological experiments proved that the SL/PP sample can improve the heat-resistant oxygen performance of PP under the thermal oxygen shearing environment. Combined with the effect of SL on the mechanical properties of PP before aging, SL has a stabilizing effect on PP thermal oxygen aging.
Illuminating the Dark or how to recover what should not be seen in FE-based classifiers

Abstract
Classification algorithms/tools become more and more powerful and pervasive. Yet, for some use cases, it is necessary to be able to protect data privacy while benefiting from the functionalities they provide. Among the tools that may be used to ensure such privacy, we are focusing in this paper on functional encryption. These relatively new cryptographic primitives enable the evaluation of functions over encrypted inputs, outputting cleartext results. Theoretically, this property makes them well-suited to process classification over encrypted data in a privacy by design’ rationale, enabling to perform the classification algorithm over encrypted inputs (i.e. without knowing the inputs) while only getting the input classes as a result in the clear.
In this paper, we study the security and privacy issues of classifiers using today practical functional encryption schemes. We provide an analysis of the information leakage about the input data that are processed in the encrypted domain with state-of-the-art functional encryption schemes. This study, based on experiments ran on MNIST and Census Income datasets, shows that neural networks are able to partially recover information that should have been kept secret. Hence, great care should be taken when using the currently available functional encryption schemes to build privacy-preserving classification services. It should be emphasized that this work does not attack the cryptographic security of functional encryption schemes, it rather warns the community against the fact that they should be used with caution for some use cases and that the current state-ofthe-art may lead to some operational weaknesses that could be mitigated in the future once more powerful functional encryption schemes are available.
