Neuronic Convolution Model_Li-Yun Fu
Authors: Fu Li-Yun
Published: June 2020

How to represent spatiotemporal information in an artificial neuron model has been a problem of longstanding interest in artificial intelligence. After a brief review of recent advances, Caianiello’s neuronic convolutional model is extended in this paper for spatiotemporal information representation. The kernel functions that correspond to the convolutional neuron’s receptive field profile can be described by neural wavelets. The convolutional neuron-based multilayer network and its back propagation algorithm are developed to perform spatiotemporal pattern processing. The results provide a natural framework for the discussion of spatiotemporal information representation in an artificial neural network

Informed consent and mental health, mainly in Spain, EU
Authors: Jose Manuel BERTOLIN-GUILLEN
Published: June 2020

Introduction: Lawfully given, informed or valid consent is considered by Spanish jurisprudence a fundamental right and entails important repercussions.

Method: Critical and theoretical examination of the matter, with special emphasis on the case of the most vulnerable people and those who require involuntary outpatient psychiatric treatment (IOT).

Results: Valid informed consent must fulfil the requirements of capacitation, willingness, information and understanding. Timely knowledge and agreement regarding by whom and how this consent must be granted are important in biomedicine and psychology in general, as well as in the specialities of psychiatry and clinical psychology in particular. It is also important to ensure valid consent for any psychotherapy, as it generally also occurs in the case of psychopharmacological treatments. This article will revise the so-named “sliding scale” to determine mental degree of competence. This concept is especially important in order to consider whether a supposed valid consent is appropriate in vulnerable people. We will talk about living will and severe mental illness concerning valid consent. The current state of psychiatric involuntary outpatient treatment in Spain will be mentioned as well as the wills of legally incapacitated individuals, elderly people or when the carer, either an individual or institution, is the main beneficiary.

Conclusions: Valid consent is necessary in every biomedical or sanitary action in general. The matter is potentially controversial if wrongful influences bear upon elderly people, incapacitated individuals and others.

Authors: Ilyushina N. A. , Revazova Yu. A.
Published: June 2020

In order to overcome resistance to individual pesticides and improve their effectiveness, formulations containing two or more active substances are constantly being developed and put on the market over recent years. Mixtures of residual amounts of pesticides can be present in water and food and enter the human and animal bodies. However, the combined effect of pesticides on living organisms, including genetic structures in cells, has not been studied enough and it is not yet possible to predict the genotoxic effects of their mixtures based on available data. The purpose of this review was to collect and summarize literature information on the genotoxicity of pesticide combinations obtained at different objects. The results of studies conducted in different countries of the world are discussed, examples of detected synergistic, additive and antagonistic effects are given, indicating the need for testing the genotoxicity of preparative forms of pesticides containing several active substances, as well as mixtures of jointly used pesticides in order to ensure the safe use of pesticides for public health.
Proteasome Inhibitors Diminish c-Met Expression and Induce Cell Death in Non-Small Cell Lung Cancer Cells

Published: June 2020

Non-small cell lung cancer (NSCLC) is the most common type of lung cancer and accounts for 85% of all lung carcinomas. The hepatocyte growth factor receptor (c-Met) has been considered as a potential therapeutic target for NSCLC. Proteasome inhibition induces cell apoptosis and has been used as a novel therapeutic approach for treating diseases including NSCLC; however, the effects of different proteasome inhibitors on NSCLC have not been fully investigated. The aim of this study is to determine a precise strategy for treating NSCLC by targeting c-Met using different proteasome inhibitors. Three proteasome inhibitors, bortezomib, MG132, and ONX 0914, were used in this study. Bortezomib (50 nM) significantly reduced c-Met levels and cell viability in H1299 and H441 cells, while similar effects were observed in H460 and A549 cells when a higher concentration (100 nM) was used. Bortezomib decreased c-Met gene expression in H1299 and H441 cells, but it had no effect in A549 and H460 cells. MG-132 at a low concentration (0.5 M) diminished c-Met levels in H441 cells, while neither a low nor a high concentration (20 M) altered c-Met levels in A549 and H460 cells. A higher concentration of MG-132 (5 M) was required for decreasing c-Met levels in H1299 cells. Furthermore, MG-132 induced cell death in all four cell types. Among all the four cell lines, H441 cells expressed higher levels of c-Met and appeared to be the most susceptible to MG-132. MG-132 decreased c-Met mRNA levels in both H1299 and H441 cells. ONX 0914 reduced c-Met levels in H460, H1299, and H441 cells but not in A549 cells. c-Met levels were decreased the most in H441 cells treated with ONX 0914. ONX 0914 did not alter cell viability in H441; however, it did induce cell death among H460, A549, and H1299 cells. This study reveals that different proteasome inhibitors produce varied inhibitory effects in NSCLS cell lines.

Authors: Alabbasi Iea , Merdan Issam , Al-Gazgooz Falih
Published: June 2020

Background: Laparoscopic sleeve gastrectomy is a well-known method for weight reduction. Post-operative weight loss is a major risk factor for gallstone formation.
Objective: To determine whether prophylactic concomitant laparoscopic cholecystectomy should be performed on all patients at the time of laparoscopic sleeve gastrostomy or not.
Patients and Methods: A retrospective and prospective study on 540 patients with morbid obesity who underwent laparoscopic sleeve gastrectomy; their BMI range was between 38 and 53, their age range was 18 to 63 years, and 335 of them were females. The exclusion criteria were patients with a history of cholecystectomy, gallstone patients or gallbladder polyps more than 1 cm in preoperative abdominal ultrasound, and those who failed to follow-up. All patients were followed up with every 6–12 months, including those who had cholecystectomy by other surgeons.
Results: During the study period, from the total 540 patients who had laparoscopic sleeve gastrectomy, 167 patients (30.92%) had cholecystectomy, out of which 20 patients (3.7%) had achieved 45% weight reduction during the first six months; while in another 6 months, 147 patients (27.22%) had cholecystectomy, achieving additional 30% weight reduction.
Conclusions: The incidence of gallstones after laparoscopic sleeve gastrostomy is about 30.92%, indicating that 69.08% will not have gallstones in the postoperative follow-up period, so it would be unwise to do prophylactic concomitant cholecystectomy for all patients.

Over the past few years, the government has given a spesific attention to the character education due to its main purpose to develop good and right behaviour for the students since their early age. To achieve this, one of them is through education. In Bali, according to the concept of its society, education is translated by local values in a simple way, such as learning while travelling, learning while singing, learning while playing a game and so on. The Balinese folklore (Satua) is an implementation of Hindu values which give an understanding on conscience and behaviour to the children since early age. This research is a qualitative research using the hermeneutics method. Bali has many literary heritages which are full of the value of character education, one of them is Satua Bali. Among the many Satua that are available, Satua that will be used is Satua I Nengah Tinggen's with titled Anak Agung di Mesir. He is one of the Balinese literary maestros. The study of this folklore refers to six pillars of character proposed by SD Westwood, covers trustworthiness, respect, responsibility, caring, citizenship, and fairness. It can be concluded that Satua is somewhat effectively used as a character education media because it contains the values ​​of character education needed for the nation's character development and can be taught early with Satua.
Savādības pievilcība: diskusija par Viktoru Igo Latvijas kultūrvidē 19.–20. gadsimta mijā
Authors: Rožkalne Anita
Published: June 2020

In the early stages of the development of the Latvian national literature, periodicals used to publish information, reflections, and overviews on foreign culture and literature parallel to (or sometimes even before) the appearance of the corresponding translations in the Latvian cultural space. The material selected for publication determined whether the rendition of the facts was factual or imaginative, saturated with details familiar to the reader, or introduced new information. Furthermore, periodicals quite often reprinted information on situations and characters found in foreign press that seemed curious or odd to their Latvian readership. The popularity of these publications, like that of light fiction, stemmed from the widespread interest in exotic narratives. Narratives about the literary works of foreign authors held a very distinctive position among this idiosyncratic material. A prime example is the overview of Victor Hugo’s writings and biography in the Latvian periodicals at the end of the 19th century, predating the translations of his works in Latvian. The discussion which took place in the public space offers an insight into the contradictory reception process of foreign literature, revealing that the formation of Latvian national identity and literature was influenced both by the openness to otherness and a variety of hermeticism or distancing from otherness.
Mikrostāsta jēdziens mūsdienu literatūrā
Authors: Babina Agata
Published: June 2020

The glorious, overwrought, and ambitious modernism of the early 20th century has gradually been replaced by minimalism in art, architecture and other cultural expressions. In such a changing environment, minimalism trends also appear in the literature. Turning to the analysis of literary fiction over the last hundred years, critics of Romanic and Anglo-Saxon literature have come to the conclusion of the emergence of a new literary genre. In Anglo-Saxon literature, among many other names of this genre, the most recognizable name is flash fiction, while in Spanish, the term microrrelato has been established in the last decade. However, in Latvian literature, the characteristics of the genre correspond to minimas written by Aivars Eipurs.
The paper aims to provide insight into the development and textual characteristics of flash fiction and to seek its equivalents in the literature of different Western nations.
The study looks at the concept of flash fiction and its synonyms in English, Spanish, French, Russian, and Polish languages, includes definitions of flash fiction as an independent literary genre of a variety of authors and sets out the key features and examples. In addition to the concept of flash fiction, it includes concepts of intertextuality and ellipsis, which, along with humor and metafiction, are essential linguistic elements of flash fiction.
Flash fiction merges different genres and their patterns into a new literary form consisting of certain linguistic, syntactical, and pragmatic texting techniques. In building the theoretical base of the study, the emphasis was placed on the critics of contemporary Spanish literature less known in Latvia, such as professor Irene Andrés-Suárez (b. 1948) of the University of Neuchatel (Switzerland), Argentinian writer and literary critic David Lagmanovich (1927–2010) and Mexican literary critic Lauro Zavala (b. 1954). Examples of the genre are mostly referred to by Hispanic authors.
Dieva īpašību atainojums latviešu tautasdziesmās teopoētikas kontekstā
Authors: Mārtuža Eva
Published: June 2020

An innovative view to theological texts as a literary genre has been established in research of the modern religions and designated as theopoetics, because, irrespective of whether a theological text is written in the poetic genre, in the form of a story or the style of a more dense, theoretical prose, it is based on the poesis: innovative, intuitive and an imaginary composition of the authors where the central figure is God. Therefore, approximately ten thousand recorded and published folk songs, as well as other Latvian folklore texts about God, are equal to theopoetics as a genre of creative writing with its specific expression tools. Folk songs are a product of purposeful human spiritual/intellectual activity and imagination, a typical cultural phenomenon of the relevant society, which helps to study the public’s views about the perception of God.
To approach adequately to analysis and interpretation of such texts, in the late 20th century, a new method of research on religious texts – theopoetics – was established. Theopoetics is a method of analysing religious texts that encourages us to look at the ancient metaphors of God from another angle. It explores the language possibilities of figuratively creating God’s patterns, unlike the previous “scientific” God’s theories as the systematic attempt of theology to find God through the living (“incarnated”) God. Theopoetics theorists accept reality as a source of divine revelation as well as personal experience and metaphor-influenced divine understanding in various religions. This method allows to establish the essence and possible interpretations of the basic metaphors used in every individual religion: 1) critically weigh up the previous explanations of God; 2) study the interaction of applied metaphors, models and concepts within religion; 3) offers the potential of transformative, revolutionary models, using the language and metaphor layer that is widely understandable and used by people in everyday life.
Research of metaphors does not impose objective or general criteria for assessing understanding of God; therefore, the aim of theopoetical discourse is not to prevent competing interpretations but to multiply the number of perceptions of God, to extend the emotional feeling, and to reveal new opinions. Folk songs figuratively represent God in metaphors and comparisons, but the theopoetics method has not been applied in the previous studies of God either because it is a relatively new methodological system, or because God’s perception in the folk songs has not been the focus of researchers of contemporary religions.
On Public-key Cryptosystem Based on the Problem of Solving a Non-Linear System of Polynomial Equations
Authors: Ghadbane Nacer
Published: June 2020

The basic idea behind multivariate cryptography is to choose a system of polynomials which can be easily inverted (central map). After that one chooses two affine invertible maps to hide the structure of the central map. Fellows and Koblitz outlined a conceptual key cryptosystem based on the hardness of POSSO. Let Fp s be a finite field of p s elements, where p is a prime number, and s ∈ N, s ≥ 1. In this paper, we used the act of GLn (Fp s ) on the set F n p s and the transformations group, to present the public key cryptosystems based on the problem of solving a non-linear system of polynomial equations

Never Stop Improving?
Authors: Biscopink Eric M.
Published: June 2020

This Comment argues that a co-tenant who improves a concurrent estate without the consent of the other co-tenant should be liable for the increased tax liability caused by the improvement. Part II surveys the current law surrounding concurrent estates, providing background to the common law rules on the various types of co-tenants. This will provide context for the subsequent argument about how property taxes could have a drastic effect on the current face of concurrent estates. The Author will overview property taxes as they relate to local property, delving into the property tax rates, in particular, and how they relate to concurrent estates.

In Part III, the Author will discuss the principles of a sound state tax policy, and weigh those principles to determine what are the most important factors in creating a tax. This will illuminate the need for a concrete rule and what that rule should be.

Part IV of this Comment will set up the central problem: whether a co-tenant can improve the concurrent estate to the extent that the property tax liability is too great for the other co-tenant, essentially improving the co-tenant out of the property. The problem poses related issues with the well-established case law. If the purpose of not allowing a co-tenant the right to contribution for improvements is to prevent a wealthier co-tenant from ousting his or her other co-tenants, then why can he or she currently do it through a loophole of creating tax liability? However, if the non-improving co-tenant is not liable for the property tax, is the purpose behind the required contribution for necessary costs void?

Part V will offer a solution to the tax liability from improvements to concurrent property. The Author will propose to close the gap in the law consistent with the rule for improvements by a co-tenant. The improving co-tenant will be liable for the rise in tax liability for any improvement done without the consent of the non-improver. Ultimately, a co-tenant should not be in danger of being ousted from a concurrent estate by an increase in tax liability due to non-consented improvements to the property owned in joint tenancy. Therefore, the Author proposes the gap in the current law be addressed with the requisite legislation.
Access to livelihood resources and choices of development strategies:
Authors: Shitima Christina Mwivei , Dimoso Romanus
Published: June 2020

This study engages with the debate in the literature on access to livelihood resources and livelihood diversification to show how differences in people’s access to resources result in differences in the choices of development strategies (DST) that people pursue for livelihoods’ enhancement. It uses a multinomial logit model to analyse how access to social and financial capitals affects people’s choices of DST in the rural river basin areas of Tanzania. Further to that, the study links the findings with policy initiatives related to the conservation of river basin resources (RBR). The study uses survey data which were supplemented by qualitative data gathered through focus group discussions. Findings show that both access to social and financial capitals affect the choice of secondary DST, though access to social capital seems to be more important in Kilombero, and access to financial capital more important in Meatu. In Kilombero, access to social capital is an important factor for people to diversify their activities away from traditional pastoralism, an activity that is not environmentally friendly. In Simiyu, access to financial capital raises the likelihood of people to participate in off-farm activities instead of other activities that make enormous use of RBR, for example, traditional pastoralism and irrigated farming.

Celiakija – tai autoimuninis plonųjų žarnų uždegimas, sukeltas Th-1 limfocitų hiperreakcijos į kviečiuose, rugiuose bei miežiuose esantį baltymą gliadiną bei lemiantis gleivinės gaurelių atrofiją, kriptų hiperplaziją ir malabsorbciją. Nustatyta, jog sergantieji šia liga linkę sirgti 1 tipo cukriniu diabetu (CD), nes abi ligas sieja bendra genetinė kilmė. Pasaulyje celiakijos dažnis 1 tipo cukriniu diabetu sergančiųjų populiacijoje yra nuo 5 iki 16 kartų didesnis nei bendrojoje. Dažnai celiakija sergant 1 tipo CD yra asimptomė, tačiau celiakijos negydant yra bloga glikemijos kontrolė, didesnė širdies ir kraujagyslių sistemos ligų rizika, didėja cukrinio diabeto komplikacijų pasireiškimo rizika jaunesniame amžiuje. Šiuo metu nėra vieningos nuomonės dėl celiakijos diagnozavimo ir gydymo sergant 1 tipo CD. Pagrindinis celiakijos gydymo būdas yra ilgalaikė begliutenė dieta, todėl šis gydymas  rekomenduojamas ir sergant abiem minėtomis ligomis, tačiau besilaikantys šios dietos sergantieji 1 tipo CD turi būti atidžiai prižiūrimi gydytojų endokrinologo ir dietologo.

Two new species and new records of darkling beetles of the tribe Helopini from Turkey and Cyprus (Coleoptera: Tenebrionidae)
Authors: Nabozhenko Maxim , Keskin Bekir , Papadopoulou Anna
Published: June 2020

Two new species of the tribe Helopini (Coleoptera: Tenebrionidae) are described from Turkey: Nalassus (Nalassus) becvari sp. nov. (Elazığ Province) and Hedyphanes (Hedyphanes) kmenti sp. nov. (Artvin Province). The first species is characterized by strongly thickened antennomeres 2–8 and differs from all Turkish Nalassus s. str. Mulsant, 1854 in the ventral aspect of eye, which bears a weak posterior ventral impression (rather than a distinct groove of other species). The second species belongs to the species group with asperate punctation of the prothoracic hypomera and differs from all Hedyphanes Fischer von Waldheim, 1820 in the presence of suberect pubescence on both sides of elytral base. Distribution of some Helopini (the Helops genus-group, subtribe Helopina) from Anatolia and Cyprus is updated with new data. Hedyphanes mannerheimi Faldermann, 1837 is recorded for Turkey (Iğdır Province) for the first time. Helops caeruleus caeruleus Linnaeus, 1758 from Pervolia is a new record for Cyprus and the occurrence is probably a result of anthropogenic introduction.

Recently a huge chunk of the population has shifted towards shower gels. The biggest reason might be the fact that shower gels can provide a better care for the skin. They were made with the motive of providing gentle cleansing and moisturizing qualities contrary to that of a regular soap, so that the people can enjoy a better skin care experience. Shower gels generally use chemicals especially sodium lauryl sulfate and betaines. These are believed to cause skin irritation and may not be washed off properly especially in hard water. The recent shower gels have a combined scrubbing effect included along with the scented or flavored body wash. For the scrubbing activity microbeads are employed. These microbeads used as a scrubber are polymers, e.g. being polyethylene or nylon etc. We know how plastics are harmful to us and the environment. And this is a cause of major concern. And since it is small in size it makes it relatively dangerous. Microbeads, because of their small size, have a large surface area by volume which allows them to accumulate highly toxic materials which are toxic to the person and the environment. To overcome the menace of microbeads we propose an alternative

The waste generated from the industries motive environmental issues. For this reason the reuse of these wastes are often emphasised.Thus Marble dust powder (MDP) is one of the fast growing waste material which can be used in the concrete production industry to minimize material use and produce financial advantage. In this study, the marble dust powder passing through 90 micron sieve, has been utilized for determining the hardened properties of concrete .The hardened properties of concrete has been determined with the effect of different rate replacement of cement by MDP.In this examination work, MDP has replaced the Ordinary Portland Cement (OPC) at an increasing rate from 0 % to 20% by weight in M30 grade concrete. The motivation behind this investigation is to examine the behavior of concrete with the substitution of cement by MDP in various extents in concrete.

Authors: Laxmeshwar Swati , N.R Deepak
Published: June 2020

This paper presents our current electronic health record ( EHR) systems with a blockchain based architecture.Designed on top of established databases held by health care organizations, the framework incorporates a blockchain approach to ensure data record accuracy and enhance network interoperability by monitoring all incidents that occurt on top of existing health service provider-maintained databases, the architecture implements a blockchain solution to ensure data record integrity and improve system interoperability by tracking all events that occur in database data. We 're also implementing a new reward system in this revised design to build new blocks on the blockchain. The design is autonomous of any particular blockchain network and accessible to more extensions; it may also be combined with other electronic storage structures needing security. It will then theoretically tie in with other electronic storage schemes needing protection from data misuse.
Mining Educational Data to Analyze Students’ Performance: A Case Study of Mawuli School, Ho
Authors: Lokpo Cephas
Published: June 2020

Data mining is the extraction of prospective valuable information from large chunk of data through the employment of many different data mining techniques. The usefulness of data mining coupled with the huge data generated in scholastic settings has made it an interesting field of research known as Educational Data Mining (EDM). The intent of EDM is to derive understanding from hidden patterns in data collected from institutions of learning to aid in identifying issues that influence students’ scholastic accomplishment, to solution of which will lead to improvement in accomplishment. Because scholastic achievement is dependent on several issues, it is essential to develop predictive models on students’ academic performance. This study’s objective, therefore, is to acquire an insight into performance through knowledge discovery by the use of simple linear regression in order to build a predictive model capable of predicting students’ grades to give a general overview of students’ performance in the WASSCE, and help improve students’ performance. In accomplishing the set objective for which the study was carried out, that is to predict the possible outcome of students in WASSCE, a widely sampled study was applied in undertaking the study (Quantitative research).
