Nikfar Domination in Fuzzy Graphs
Authors: Nikfar Mohammadesmail
Published: May 2019

The aim of this expository article is to present recent developments in the centuries-old discussion on the interrelations between several types of domination in graphs. However, the novelty even more prominent in the newly discovered simplified presentations of several older results. The main part of this article, concerning a new domination and older one, is presented in a narrative that answers two classical questions: (i) To what extend must closing set be dominating? (ii) How strong is the assumption of domination of a closing set? In a addition, we give an overview of the results concerning domination. The problem asks how small can a subset of vertices be and contain no edges or, more generally how can small a subset of vertices be and contain other ones. Our work was as elegant as it was unexpected being a departure from the tried and true methods of this theory that had dominated the field for one fifth a century. This expository article covers all previous definitions. The inability of previous definitions in solving even one case of real-world problems due to the lack of simultaneous attentions to the worthy both of vertices and edges causing us to make the new one. The concept of domination in a variety of graphs models such as crisp, weighted and fuzzy, has been in a spotlight. We turn our attention to sets of vertices in a fuzzy graph that are so close to all vertices, in a variety of ways, and study minimum such sets and their cardinality. A natural way to introduce and motivate our subject is to view it as a real-world problem. In its most elementary form, we consider the problem of reducing waste of time in transport planning. Our goal here is to first describe the previous definitions and the results, and then to provide an overview of the flows ideas in their articles. The final outcome of this article is twofold: (i) Solving the problem of reducing waste of time in transport planning at static state; (ii) Solving and having a gentle discussions on problem of reducing waste of time in transport planning at dynamic state. Finally, we discuss the results concerning holding domination that are independent of fuzzy graphs. We close with a list of currently open problems related to this subject. Most of our exposition assumes only familiarity with basic linear algebra, polynomials, fuzzy graph theory and graph theory.

Published: May 2019

High-frequency neuroelectric signals like electroencephalography (EEG) or magnetoencephalography (MEG) provide a unique opportunity to infer causal relationships between local activity of brain areas. While causal inference is commonly performed through Classical Granger causality (GC) based on multivariate autoregressive models, this method may encounter important limitations (e.g. data paucity) in the case of high dimensional data from densely connected systems like the brain. Additionally, physiological signal often present long-range dependencies which commonly require high autoregressive model orders / number of parameters. We present a generalization of autoregressive models for GC estimation based on Wiener-Volterra decomposition with Laguerre polynomials as basis functions. In this basis, the introduction of only one additional global parameter allows to capture to capture arbitrary long dependencies without increasing model order, hence retaining model simplicity, linearity and ease of parameters estimation. We validate our method in synthetic data generated from families of complex, densely connected networks and demonstrate superior performance as compared to classical GC. Additionally, we apply our framework to studying the directed human brain connectome through MEG data from 89 subjects drawn from the Human Connectome Project (HCP) database, showing that it is able to reproduce current knowledge as well as to uncover previously unknown directed influences between cortical and limbic brain regions.

Mathematics support for science: a reflection of a blended and online development project
Authors: Ahmed Shazia , Paschke Beth , Milne Sue , Barr Niall
Published: May 2019

The diverse range of backgrounds that students bring to university has many advantages, but also some challenges such as a wide range of mathematical experience and ability. A particular issue identified by staff teaching mathematics to the Science Fundamentals cohort was lack of engagement due to the material presented being too easy or too difficult, with the main concerns directed towards students who are weak at mathematics and others who lack some of the basic skills necessary for a successful undergraduate experience at Glasgow.Our experience from the Science Fundamentals course is that traditional lectures are a poor way to motivate the weaker students and the more collaborative models of teaching such as online and blended learning may be more appropriate. Following a two-year project, a suite of online resources was developed to supplement course material; students completed a ‘Mathematics Confidence Test’ to determine the level of support required and the number of mathematics lectures was cut down and replaced with tutorials aimed at the weaker students.We will discuss our experiences of running this project, reflect on feedback and discuss further plans for supporting the Science Fundamentals cohort in subsequent years.
Near-Wellbore Model To Analyze Particulate Diversion in Carbonate Acidizing
Authors: Safari Reza , Shahri Mojtaba P. , Smith Clayton , Fragachan Francisco
Published: May 2019

In this paper we present an integrated analysis method for understanding and quantifying the effect of particle-jamming near the entrance of a perforation/wormhole tunnel. Advanced wellbore-scale, 3D numerical studies with coupled computational fluid dynamics (CFD), and a discrete-element model (DEM) were performed to study the different mechanisms involved in particulate diversion. The results of the wellbore-scale simulation were translated into an engineering-particulate-diversion model on the basis of the diversion mechanisms from the simulation. The model was then incorporated into an integrated carbonate-acidizing simulator.

Particulate diversion is not generally used in carbonate acidizing because of the formation of wormholes and the potential difficulty in removing particles from the induced perforation/wormhole tunnels. This new degradable particulate system addresses the issue and presents an efficient approach for diverting acid in carbonate stimulation. Detailed physics-based simulations demonstrated that the induced perforations/wormholes would plug through two distinct mechanisms and either temporarily seal the entrance of small-scale perforations/wormholes with a combination of small and large particles, or bridge large particles along tapered paths of perforations/wormholes and form a temporary filter cake deeper within the opening. Either of these diversion mechanisms would decrease the injectivity locally and promote fluid diversion from inside the well into other normally understimulated locations. These procedures were translated into engineering equations, thus providing the modeling capabilities.

An integrated simulator was used to optimize the acid stimulation of a vertical wellbore and explain the impact of operational parameters and subsurface conditions on the stimulation efficiency. The model results showed that most bullheaded treatments were significantly improved by using the particulate diversion system. It was shown that the developed skin from jammed particulates provided a considerable diversion. The results also demonstrated the relationship between the treatment pressure, the quality of diversion, and the subsurface conditions (e.g., permeability, porosity, reservoir pressure, and temperature).

ACUTE KIDNEY INJURY DURING CRITICAL ILLNESS – A GLOBAL CHALLENGE
Authors: Ostermann M.
Published: May 2019

The report is devoted to the problem of acute kidney injury (AKI) in critically ill patients. Currently, the clinical definition of AKI is based on the assessment of increasing serum creatinine, but this method has a number of significant drawbacks. Perhaps the use of biomarkers for early detection of renal injury will improve diagnostic results. Up to date, no specific drug therapy for AKI has no available. The therapeutic tactics are based on the assessment of the risk of development AKI in critically ill patient, hemodynamic optimization, revision of drug therapy to exclude nephrotoxic drugs and the use of renal replacement therapy (RRT). Despite the numerous studies and the presence of multiple researches of AKI, there are many unclear issues related, for example, how to choose tactics of infusion therapy, the use of vasopressor support in patients with AKI, the time of the beginning and the choice of the mode of RRT, the feasibility of combining several technologies of extracorporeal hemocorrection. It is important to define how to improve the short-term prognosis and the long-term consequences of renal dysfunction.
IMMUNOMODULATION, IMMUNOSTIMULATION AND EXTRACORPOREAL BLOOD PURIFICATION IN SEPSIS: POTENTIALLY BENEFICIAL TECHNIQUES IN CARDIAC SURGERY
Authors: Gianluca P. , Nagy Á
Published: May 2019

Sepsis is a potentially life-threatening state caused by an infection and an inadequate, dysregulated host immune response. Focusing on cardiac surgery, the prevalence of sepsis is low, after procedures situated between 0.39% and 2.5%. Nevertheless, the current life-expectancy of septic patients are poor, mortality varying from 65% to 79%.

Pathophysiology and immunopathology of sepsis is still unclear. Actually we consider sepsis as a dynamic process with two different sides. Both immune hyperactivity and immune suppression are presented during the progression. Although immunomodulation is not a fresh idea in the treatment of sepsis. Currently the diagnosis of sepsis is based on clinical signs. The biomarkers and molecular diagnostic tools are insufficient.

The actual concept of immunopathophysiology in sepsis is based on the idea of a dynamic parallel immune response, both pro- and antiinflammatory processes are presented from the beginning. Equilibrium may be the key in the immune response of sepsis. Immune system tries to maintain the homeostatic environment during sepsis via pro- and antiinflammatory processes. In case of an unbalanced, dysregulated and radical (in both directions) response mortality become frightfully high. Infectional source control, adequate antibiotic therapy and organ support are the three corner stones in the treatment of sepsis since the definition of sepsis born.

In our review we would like to add a detailed overview on two promising modalities of immunomodulation: (1) extracorporeal blood purification; (2) immunostimulation.

The purposeof present article is to give an up-to-date, comprehensive review on the utilization of extracorporeal blood purification techniques and immunostimulation in septic patient after cardiac surgery.

Kivándorlás és szabályozása Kínában
Authors: Koudela Pál
Published: May 2019

Az 1980-as évektől Kína lehetővé tette, hogy a lakosság egy szűkebb csoportja legálisan is elhagyhassa az országot. A kivándorlás akkor szoros irányítás alatt állt és gazdasági célokat szolgált. Korlátozás a Csing dinasztia kora óta jelen van, azonban az utóbbi két évtizedben egyre kevesebb formális elem gátolja a kiutazást és a kinntartózkodást, s a vezetés egyre rugalmasabban gondolkodik a kivándorlók gazdasági hasznáról; már nem csupán a szellemi tőke behozatalát, a közvetlen hazai befektetéseket, hanem a globális hálózat építését is szem előtt tartva. A kivándorlás Kínából mégis szerény, s a magas társadalmi státuszú csoportokra jellemző. Az elvándorlás nagyságát a befektetői csoportok és a diákság szerepének növekedése határozza meg. Ennek okai a hazai gazdaság bővülésében és a befogadó országok korlátozásaiban kereshetők. A diákság kivándorlásának kezdetét a „reform és nyitás” politikája jelentette, a kormány kifejezetten a szellemi  tőke felhalmozását támogatta. Kínában különösen értékes a külföldön megszerzett diploma, noha a felsőoktatás fejlesztése elvben megoldotta az utánpótlást. A tanulási szándékkal kivándorlók jelentős hányada azonban ma sem tér vissza Kínába. A szakképzetlen vagy alacsonyan képzett fizikai dolgozók kivándorlását szorosan ellenőrzi a kormányzat, annak iránya és feltételrendszere a külföldi befektetések változásaitköveti. Mára ugyanakkor jelentős liberalizáció zajlott le ezen a területen is.

Published: May 2019

Laguna de Bay or Laguna Lake is one of the six major lakes in the Philippines to be in close contact with population activities due to the expansion of urban settlements in the immediate cities surrounding the lake, thus pushing the population to settle upon its shores. To date, there are no data showing the biodiversity of free-living amoebae (FLA) present in this lake. The present study aims to isolate and identify the FLA present in Laguna de Bay, Philippines. Thirty subsurface water samples were taken from Laguna De Bay using random purposive sampling in May 2018 and were examined for amoebic growth under light microscopy (LM). Results show that 8 out of 30 (26.6%) water samples were positive for amoebic growth and were further tested for more advanced data and genetic variation of the species. Initial molecular analysis using polymerase chain reaction (PCR) and sequencing showed the presence of potentially pathogenic FLA Naegleria australiensis (MK418954). The detection of potential pathogenic FLA in lakes and dams may prove useful in preventing and controlling possible human infections in the country. More data from this study will aid in public awareness and establishing safety guidelines and control programs.

Low Efficacy of Hypochlorous Acid Solution Compared to Povidone-iodine in Cataract Surgery Antisepsis
Authors: Kanclerz Piotr , Grzybowski Andrzej , Olszewski Bogdan
Published: May 2019

Background:

Hypochlorous Acid Solution (HAS) is a non-irritating, odorless and transparent, pH-neutral substance having antimicrobial activity.

Objective:

The study aimed to compare the efficacy of HAS with a 10% povidone-iodine (PVI) solution for antisepsis in Phacoemulsification Cataract Surgery (PCS).

Methods:

Consecutive patients undergoing PCS in the Elbląg City Hospital, Poland, were enrolled in this prospective trial. In the morning just before surgery a swab was taken from the inferior conjunctival fornix of the eye that was to be operated. Patients were assigned to receive conjunctival irrigation with PVI or HAS in the operating room. Three minutes after lavage with PVI or HAS, conjunctival swabs were taken. During surgery the cornea and conjunctival sac were irrigated with Ringer’s lactate. The last swab was taken before removing the eye speculum.

Results:

Overall, 110 patients completed the study; there were 59 patients in the PVI group and 51 patients in the HAS group. Conjunctival lavage with 10% PVI resulted in a decrease in bacterial load, while HAS application did not. In the HAS group a reduction in bacterial load was found after surgery. Patients after HAS irrigation reported significantly less discomfort associated with conjunctival lavage than with PVI. None of the patients developed postoperative endophthalmitis or any type of eye inflammation within the follow-up period.

Conclusions:

This study confirms the excellent antibacterial activity of a 10% povidone-iodine solution used for three minutes before cataract surgery. Conjunctival irrigation with Ringer lactate during PCS decreased the bacterial load of the conjunctival sac.

Nowadays majority of navigation methods, used in unmanned flying vehicles, are based on satellite navigation systems, such as GPS or GLONASS, or are amplified with them. But hardware, that uses such systems, can’t work in difficult conditions, for example causes by relief: with insufficient number of satellites or at low satellite signal. Satellite navigation systems are vulnerable for methods of radio defense: satellite signal can be deadened or replaced. That is why such systems usage is unacceptable while critical missions during military operations, emergency or reconnaissance. The article briefly describes components used for building alternative satellite-free navigation systems for flying vehicles. For each component its purpose and brief description of working principle are given, advantages and disadvantages are considered.

PROBLEMS OF AXIOM APPLICATION OF AGENTS BELONGING TO MULTIPLE MULTIAGENT SYSTEMS IN RESEARCH OF ORGANIZATIONAL AND ORGANIZATIONALTECHNICAL SYSTEMS FUNCTIONING
Authors: Babich M. Yu
Published: May 2019

The problems of functioning of organizational and organizational‑technical systems, which are proposed to be supposed as multi‑agent systems, are considered. One of the important subsystems is a control subsystem that performs soft management of rational agents that are locates simultaneously in the contour of several systems with different performance objectives. This property of agents is described by the presented axioms. Three levels of studied objects are distinguished: the level of the agent, the level of systems and the level of supersystems. The necessary and sufficient conditions under which the agent’s systems can exert significant influence on each other are analyzed. At the agent level, decision makers are considered, that is, agents belonging to the management subsystem that function in the real and virtual systems. It is shown that the goals of the virtual and real systems may not coincide. For the system level, statements are made about the use of system resources in the process of agent’s functioning, the definition of acceptable algorithms for achieving the goal is formulated and their properties, in which achieved two non‑coinciding goals are analyzed. The general algorithm of agent’s activity in relation to the system and the system in relation to agents is given. The criterion of the possible achievement of the goal for systems is given. At the level of supersystems, statements are given that are consequences of the assertions given at the system level, as well as a general criterion for achieving the goal for supersystems.

The paper describes an unconventional method of solving the amplitude-phase problem. The main properties of the Hilbert transform in the discrete and continual cases for one-dimensional and two-dimensional mappings are considered. These transformations are widely used to solve amplitude-phase problem. A numerical method for solving of two-dimensional amplitudephase problem is proposed. Preliminary information about the zeros of the Fourier transform of the initial signal is not required for this method. The method is based on the apparatus of nonlinear singular integral equations. Computational schemes for solving the corresponding nonlinear singular integral equations are developed. An algorithm for finding initial values for realization of iterative methods is proposed. Quadrature formulas of the calculation of singular integrals are proposed.

The paper considers an embodiment of the antenna design based on a flat non‑axis‑symmetrical transreflector made by using multilayer printed circuit board technology. The construction principle of a flat non‑axis‑symmetrical transreflector by cutting it from the flat polarizing structure is given. The form of the flat multi‑layer non‑axisymmetric transreflector board is determined by the projection of the non‑axisymmetric parabolic transflector onto a plane perpendicular to the focal axis. An electrodynamic model of the antenna with a flat non‑axis‑symmetrical reflector to study the radiation characteristics in the UHF range was constructed. A comparative analysis of the radiation characteristics of antennas on the basis of planar multilayer axisymmetric and flat multilayer non‑axis‑symmetrical transreflectors was performed. A number of technological advantages of the developed flat structure over a non‑axis‑symmetrical parabolic transreflector due to use of the known technology of multilayer printed circuit boards is also described.
