The Effect of the Vertical Acceleration on Stability Assessment of Seismically Loaded Earth Dams
Authors: Korzec Aleksandra 
Published: April 2017

Abstract
In the assessment of slope stability, the vertical component of acceleration is commonly neglected. However, signal analyses performed on a large number of acceleration time histories have revealed that the vertical peak ground acceleration can be as high as the horizontal one. In this paper, a method of slope stability analysis regarding the vertical component of acceleration is proposed. It considers a rigid body system affected by the acceleration time histories in both horizontal and vertical directions. In a general case, the strength of the contact between acceleration components is time dependent. Parametric analysis was performed on the basis of cyclic harmonic loading, assuming a safety criterion in the form of permanent displacement. The results, for both harmonic and real acceleration time histories, were compared with the results of the commonly used Newmark’s sliding block approach, which revealed significant differences in permanent displacements calculated by the two methods.
Mechanical Properties of Granular Soils: Triaxial versus Plane Strain Investigations
Authors: Sawicki Andrzej , Sławińska Justyna , Mierczyński Jacek , Smyczyński Marcin 
Published: April 2017

Abstract
The paper compares the pre-failure behavior of granular soils investigated in the classical triaxial apparatus and in the true triaxial apparatus, under plane strain conditions. Both experiments are described within the framework of an incremental model of the pre-failure behavior of sands. The methods of tensor algebra are used to compare theoretical predictions with experimental results. The analysis presented deals with the pre-failure deformations of fully drained sand, as well as with its undrained behavior, including static liquefaction and the specific behavior of an initially dilative soil. Some key questions of soil mechanics are discussed, for instance, whether soil parameters determined from one configuration, such as triaxial conditions, can be applied in other cases.
Calculating Distributed Denial of Service Attack Probability in Bloom-Filter based Information-Centric Networks

Published: April 2017

Abstract
Information-Centric Networking (ICN) is an emerging networking technology that has been designed to directly operate on named content/information objects, rather than relying on the knowledge of the content location. According to the ICN principles, a user requests the information object by its name or some other form of object identifier. After that, the ICN system is responsible for finding the particular object and sending it back to the user. Despite a large number of works on ICN in recent years, ICN systems still face security challenges. This is especially true when considering different types of alternative networks, such as the wireless community networks (WCNs). In this work, we explore the applicability of ICN principles in the challenging and unpredictable environments of WCNs. We consider stateless content dissemination using Bloom filters (BFs) and analyze two BF based approaches: the traditional single-stage BF and its generalization, the multi-stage BF. We focus on the security aspects of BF based approaches and in particular on distributed denial of service (DDoS) attacks. Finally, we investigate the attack probability for various system and network parameters, such as the number of hash functions, the BF maximum fill factor, and the number of hops toward the victim node.
Congestion Probabilities in Erlang-Engset Multirate Loss Models under the Multiple Fractional Channel Reservation Policy
Authors: Moscholios Ioannis D. 
Published: April 2017

Abstract
A communication link that accommodates different service-classes whose calls have different bandwidth requirements and compete for the available bandwidth under the Multiple Fractional Channel Reservation (MFCR) policy is considered. The MFCR policy allows the reservation of real number of channels in order to favor high speed calls. Two call arrival processes are studied: i) the Poisson (random) process and ii) the quasi-random process. In the first case, calls come from an infinite number of sources while in the second case calls are generated by a finite number of sources. To determine call blocking probabilities for Poisson arriving calls, recursive formulas are proposed based on reverse transition rates. To determine time and call congestion probabilities for quasi-random arriving calls, recursive formulas are proven based on the fact that the steady state probabilities cannot be described by a product form solution. The accuracy of the new formulas is verified through simulation.
Sub-Sampling in OFDM with Constant Time Signal Recovery
Authors: Petrellis Nikos 
Published: April 2017

Abstract
The sub-sampling method for Orthogonal Frequency Division Multiplexing proposed recently, has been extended in this paper allowing the Analog-to-Digital Converter on the receiver side to operate in low power mode, up to 3/4 of the time. The predictability of the parity patterns generated by the Forward Error Correction encoder of the transmitter, when sparse data are exchanged, is exploited in order to define appropriate Inverse Fast Fourier Transform input symbol arrangements. These symbol arrangements allow the substitution of a number of samples by others that have already been received. Moreover, several operations of the Fast Fourier Transform can be omitted because their result is zero when identical values appear at its input. The advantages of the proposed method are: low power, higher speed and fewer memory resources. Despite other iterative sub-sampling approaches like Compressive Sampling, the proposed method is not iterative and thus it can be implemented with very low complexity hardware. The simulation results show that full input signal recovery or at least a very low Bit Error Rate is achieved in most of the cases that have been tested.

Published: April 2017

Abstract
Periocular biometrics is a relatively new field of research, and only several publications on this topic can be found in the literature. It can become a promising feature that can be used independently or as a complement to other biometrics. In this work, the recognition rates of periocular biometrics on a single acquisition device and inter-device database is verified and the impact of different image sources on the performance of recognition algorithms is investigated. For this purpose a NearInfrared Light database was collected. The database contains images taken by two acquisition devices. In order to test the periocular biometric trait, three feature extraction methods are chosen: Histograms of Oriented Gradients, Local Binary Patterns and Scale Invariant Feature Transform. The fusion of these methods is also proposed and it is tested on inter-device database. The feasibility of applying periocular recognition as an individual decision module for a biometric system is assessed. Experimental results yield Equal Error Rate of 17.65 for right eye using inter-device database of 640 gallery periocular images for each eye side taken from 32 different individuals (20 images per individual for each eye side). These results are obtained by the optimal weighted sum fusion of the three feature extraction methods.

Summary
Breast cancer is the most common cancer in women worldwide. The standard for detecting it includes clinical exam, mammography and fine-needle aspiration cytology. Our aim was to establish the role of the tru-cut biopsy in the diagnosis of malignant breast lesions. We provideatwo-year retrospective clinical study defining 98.67%sensitivity, 100%specificity, 100%positive predictive value, 80%negative predictive value and an overall diagnostic accuracy of 98.73%. In 89.1%of the malignant lesions, the sample was adequate to define the receptor status. Therefore, tru-cut biopsy is an easy, cheap, safe and accurate alternative to fine-needle aspiration cytology in the diagnosis of breast lesions.

Summary
Asthma and allergic rhinitis are common in childhood. Establishing sensitization to aeroallergens is crucial to effectively prevent exacerbation of these respiratory allergic diseases. The study aimed to evaluate sensitization to the most common aeroallergens in children with asthma and allergic rhinitis.We establishedacorrelation between patients sensitized to indoor, outdoor and simultaneously to both allergens. The study population consisted of 276 patients (168 boys and 108 girls) ages 4 to 16 years with asthma (A) and allergic rhinitis (AR). Skin prick tests were performed with 21 commercial allergen extracts: pollens, mites, epithelia and insects, and molds. We found that 217 patients were sensitized to at least one aeroallergen: 117 patients hadapositive result to mites, 92 to pollens, 72 to epithelia and insects, and 63 - to mold allergens. Dermatophagoides pteronyssinus was the most prevalent aeroallergen. Sensitized only to indoor allergens were 104 patients, 60 - only to outdoor allergens, and 53 were sensitized to both. Mites were the most frequent aeroallergens in children with Aand AR. Lately there has been foundasignificant increase in rates of sensitization to mold allergens, especially to Alternaria alternata. Our study has confirmed the dominant role of indoor allergens in children with respiratory allergic diseases.
The Muses in Mourning: Identity and Classicism in Calvinist Heidelberg
Authors: Tipton Joseph A. 
Published: April 2017

Abstract
This paper explores the attitude of sixteenth-century Protestant reformers towards Renaissance humanism and classical learning by examining an eclogue composed in Doric Greek by the Heidelberg arts professor Simon Stenius. Reading Stenius’ eclogue against his classical models, Theocritus (Idylls 1 and 7) and Homer’s Phaeacian narrative (Odyssey, Bks 5–7), it points out the meaning involved in the way Stenius characterizes the dismissal of the Calvinist faculty from Heidelberg upon the accession of the unsympathetic Ludwig VI. It notes how Stenius uses the pastoral genre to infuse his own work with an air of displacement and how he transposes the image of the shipwrecked Odysseus onto his own exiles in order to imply their loss of identity. When this loss of identity is soon given further definition by the ecphrasis of a rustic cup which inverts the cup described in Theocritus Idyll 1, Stenius’ attitude to classical learning is revealed: The cup not only signifies a silencing of the Muses, but – most importantly – it joins the Muses together with the Heidelberg Protestants in a mutual association of mourning. The sum total is the location of the voice and identity of the Heidelberg Calvinists within the highest registers of classical literature.

Abstract

Introduction: The functions and mechanisms of prion proteins (PrPC) are currently unknown, but most experts believe that deformed or pathogenic prion proteins (PrPSc) originate from PrPC, and that there may be plural main sites for the conversion of normal PrPC into PrPSc. In order to better understand the mechanism of PrPC transformation to PrPSc, the most important step is to determine the replacement or substitution site.

Material and Methods: BALB/c mice were challenged with prion RML strain and from 90 days post-challenge (dpc) mice were sacrificed weekly until all of them had been at 160 dpc. The ultra-structure and pathological changes of the brain of experimental mice were observed and recorded by transmission electron microscopy.

Results: There were a large number of pathogen-like particles aggregated in the myelin sheath of the brain nerves, followed by delamination, hyperplasia, swelling, disintegration, phagocytic vacuolation, and other pathological lesions in the myelin sheath. The aggregated particles did not overflow from the myelin in unstained samples. The phenomenon of particle aggregation persisted all through the disease course, and was the earliest observed pathological change.

Conclusion: It was deduced that the myelin sheath and lipid rafts in brain nerves, including axons and dendrites, were the main sites for the conversion of PrPC to PrPSc, and the PrPSc should be formed directly by the conversion of protein conformation without the involvement of nucleic acids.
Distribution extension ofAteles chamek(Humboldt 1812) in the southwestern Brazilian Amazon: identification by visual evidence and fecal DNA
Authors: Nunes André Valle , Koroiva Ricardo , Gomes Vanessa Gabrielle Nóbrega , Orsini Vinícius Santana 
Published: April 2017

AbstractOne group ofAteles chamek(Humboldt 1812) was observed during 12 days in the Vila Bela da Santíssima Trindade municipality, in the state of Mato Grosso. During that time fecal samples (n=10) were collected and molecular sequencing was used to confirm species identification. The results suggest that the particular pattern of facial hair color observed in this group may be used for differentiation from other sub-populations; however, a deeper study is required for confirmation of these results. This record represents the most southwestern observation of this species, and increases the geographic distribution ofA. chamekfor about 16 km into the southern Brazilian Amazon. Taking into consideration the threatened status of this species of monkey, and that this region is under constant intensive deforestation, it is important to highlight that ecological studies and conservation activities require urgent development.
Energy Efficiency of a Biofuel Production System
Authors: Wasiak Andrzej , Orynycz Olga 
Published: April 2017

Abstract
Manufacturing engineering is supposed to provide analyses related to various aspects of manufacturing and production in order to maximise technological, energy, and economic gains in relevant production processes. The present paper gives a recapitulation of several publications by present authors, presenting considerations of the energy efficiency of biofuel production. The energy efficiency is understood as the ratio of energy obtained from biofuels produced basing on crops from a particular area to the energy required to satisfy needs of all subsidiary processes assuring correct functioning of the production system, starting from operations aimed to obtain agricultural crops, and ending with the conversion of the crops onto biofuels.
Derived by the present authors, the mathematical model of energy efficiency of biofuel production is extended to a more general form, and applied to the analysis of quantitative relations between energy efficiency of sc. “energy plantations”, and further elements of biofuel production system converting harvested biomass into biofuel. Investigations are aimed towards the determination of the role of biomass as a source of energy.

Cooperative Authoritarians and Regime Stability
Authors: Fuller Clay Robert 
Published: April 2017

AbstractThis article assumes that the post-cold war unipolar global power structure marked the beginnings of a two-level game of national survival involving an international process of “othering,” where the winning democracies and their leaders (the “West”) view many non-democracies and their leaders as threats that they must convert, subjugate, or eradicate. Using new data on special economic zones (SEZs), I find that geographically restricting economic liberalization and reducing competition from opposition parties increases authoritarian stability and durability in this new environment.
Linguistic record of suffering in pain disease (Wallenberg syndrome) in “The Diary without vowels” by Aleksander Wat
Authors: Jaxa-Rożen Hanna 
Published: April 2017

AbstractThe elaboration is rooted in the humanities, it constitutes a so-called case study and it suits the discussion on the significance of psychosocial, biographic and axiological factors in the study of people with disabilities. The Diary by Aleksander Wat, a poet and intellectualist constitutes an extraordinary and the only such mature testimony of suffering written in Polish, a linguistic record of pain in Wallenberg syndrome. Raising awareness and the holistic approach to disability is particularly important if rehabilitation is almost impossible. Apart from physical pain, mental pain is equally significant, and a physiotherapist with their compassion and understanding can significantly alleviate suffering of the patient and their loved ones. In the elaboration significance of the humanistic coefficient is highlighted, the application of which in the rehabilitation interaction protects both sides of the contact from the asymmetry of power relations.
Children immunization – knowledge and attitudes of parents
Authors: Trojanowska Alina , Zarzycka Danuta , Brodowicz-Król Magdalena , Jędrzejewski Arkadiusz , Wiktor Anna 
Published: April 2017

Abstract
Aim. The aim of the study was to investigate parents’ knowledge and attitudes towards compulsory immunization of their children.
Material and methods. The research was conducted with the survey questionnaire among 110 randomly chosen parents aged 18-40 whose infants were inpatients at the University Children’s Hospital in Lublin.
Results. The study revealed that parents were poorly informed about the age of the first vaccination of their infant, compulsory and recommended vaccines, combined vaccines, contraindications for vaccination and adverse reactions following immunization. More than 50% of the parents had a rather positive attitude towards vaccination. However, one fifth admitted that they had seen campaigns which presented immunization of children as harmful. The most popular opinion among the respondents was that compulsory and recommended vaccinations for children should be given only against the most dangerous diseases. The majority of parents considered vaccinations to be safe and only a small percentage of parents were against immunizing their children due to possible health complications. Most of the parents were willing to immunize their children with all the compulsory vaccines and only several recommended ones (as they are not free of charge). Many of them declared they would choose combined vaccines.
Conclusions. Attitudes of parents towards immunization of children varied in the studied group. We concluded that parents were generally poorly informed about immunization of infants. The fact that knowledge about vaccinations may influence parents’ future decisions to protect their children against numerous infectious diseases calls for intensified education on the subject.
Principles for the Safe Moving and Handling of Patients
Authors: Wanless Stephen 
Published: April 2017

Abstract
Human movement when walking or running is a widely researched area. However, there is an increased incidence of musculoskeletal injury from poor positioning when moving and handling patients amongst healthcare professionals and is one of the main causes of long term musculoskeletal health problems. In the clinical area, an individual’s musculoskeletal health system is subjected to mechanical loading, increasing the body’s stress and strain limits, and once these are exceeded injury occurs. The risk of pain and injury has a direct relation from the over use of poor posture from poor moving and handling, which in turn can cause loss of strength and reduce musculoskeletal function. This can be changed through healthcare workers adopting safe biomechanical body movements during patient handling tasks.
Cross-Device Tracking: Measurement and Disclosures

Published: April 2017

AbstractInternet advertising and analytics technology companies are increasingly trying to find ways to link behavior across the various devices consumers own. Thiscross-device trackingcan provide a more complete view into a consumer’s behavior and can be valuable for a range of purposes, including ad targeting, research, and conversion attribution. However, consumers may not be aware of how and how often their behavior is tracked across different devices. We designed this study to try to assess what information about cross-device tracking (including data flows and policy disclosures) is observable from the perspective of the end user. Our paper demonstrates how data that is routinely collected and shared online could be used by online third parties to track consumers across devices.
