Multilevel Monte Carlo by using the Halton sequence
Authors: Nagy Shady Ahmed , El-Beltagy Mohamed A. , Wafa Mohamed 
Published: May 2020

AbstractMonte Carlo (MC) simulation depends on pseudo-random numbers. The generation of these numbers is examined in connection with the Brownian motion. We present the low discrepancy sequence known as Halton sequence that generates different stochastic samples in an equally distributed form. This will increase the convergence and accuracy using the generated different samples in the Multilevel Monte Carlo method (MLMC). We compare algorithms by using a pseudo-random generator and a random generator depending on a Halton sequence. The computational cost for different stochastic differential equations increases in a standard MC technique. It will be highly reduced using a Halton sequence, especially in multiplicative stochastic differential equations.

AbstractIn 2018, Das et al. [Characterization of rough weighted statistical statistical limit set, Math. Slovaca68(4) (2018), 881–896] (or, Ghosal et al. [Effects on rough𝓘-lacunary statistical convergence to induce the weighted sequence, Filomat32(10) (2018), 3557–3568]) established the result: The diameter of rough weighted statistical limit set (or, rough weighted 𝓘-lacunary limit set) of a sequencex= {xn}n∈ℕis2rlim infn∈Atn$\begin{array}{} \frac{2r}{{\liminf\limits_{n\in A}} t_n} \end{array}$if the weighted sequence {tn}n∈ℕis statistically bounded (or, self weighted 𝓘-lacunary statistically bounded), whereA= {k∈ ℕ :tk<M} andMis a positive real number such that natural density (or, self weighted 𝓘-lacunary density) ofAis 1 respectively. Generally this set has no smaller bound other than2rlim infn∈Atn$\begin{array}{} \frac{2r}{{\liminf\limits_{n\in A}} t_n} \end{array}$. We concentrate on investigation that whether in aθ-metric space above mentioned result is satisfied for rough weighted 𝓘-limit set or not? Answer is no. In this paper we establish infinite as well as unboundedθ-metric space (which has not been done so far) by utilizing some non-trivial examples. In addition we introduce and investigate some problems concerning the sets of rough weighted 𝓘-limit points and weighted 𝓘-cluster points inθ-metric space and formalize how these sets could deviate from the existing basic results.
Sociocultural linguistic approaches to code switching in Japanese women’s talk in interaction: Region, gender, and language
Authors: Didi-Ogren Holly HK 
Published: May 2020

AbstractThis article takes a sociocultural linguistic approach to code switching in investigating discursive functions of shifts between Standard Japanese and a regional dialect (Iwate Dialect) in women’s activity-centered, naturally occurring interactions. The paper extends previous scholarship to a consideration of how shifts are used for discursive functions such as expressing or seeking alignment; provides support for taking a talk-in-interaction theoretical perspective on code switching; and articulates a basis of support for this theoretical perspective by suggesting a methodological approach that combines close analysis of stretches of talk (DA/CA) with contextual information that informs our understanding of such talk (ethnography of communication). Furthermore, the paper illustrates the intersection of gender, region, and competing language ideologies; and contributes to the lacuna of language-in-use research on dialects in Japan. Excerpts are drawn from a data set of naturally-occurring interactions compiled over two years of fieldwork in Iwate Prefecture, Japan.
Continuously-tunable Cherenkov-radiation-based detectors via plasmon index control
Authors: Günay Mehmet , Chuang You-Lin , Tasgin Mehmet Emre 
Published: May 2020

Abstract
A recent study [PRB 100, 075427 (2019)], finally, demonstrated the plasmon-analog of refractive index enhancement in metal nanostructures (MNSs), which has already been studied in atomic clouds for several decades. Here, we simply utilize this phenomenon for achieving continuously-tunable enhanced Cherenkov radiation (CR) in MNSs. Beyond enabling CR from slow-moving particles, or increasing its intensity, the phenomenon can be used in continuous-tuning of the velocity cutoff of particles contributing to CR. More influentially, this allows a continuously-tunable analysis of the contributing particles as if the data is collected from many different detectors, which enables data correction. The phenomenon can also be integrated into lattice MNSs, for continuous medium tuning, where a high density of photonic states is present and the threshold for the CR can even be lifted. Additionally, vanishing absorption can heal radiation angle distortion effects caused by the metallic absorption.

Determining the quality of paper substrates containing triticale pulp for printing industry
Authors: Bates Irena , Plazonić Ivana , Radić Seleš Valentina , Barbarić-Mikočević Željka 
Published: May 2020

AbstractToday, the paper industry is faced with a global deficiency of raw wood materials, so alternative sources of virgin cellulose fibres are playing an important role in paper production. Agricultural countries produce large quantities of crop farming by-products such as straw, which is an interesting alternative raw material for cellulose fibres. Straw is used in many industries because of its numerous advantages: animal food industry, biofuel industry, construction industry and as artistic material. The potential use of straw production residues is of great importance in paper and printing industry. The focus of this research is on triticale straw, which was used as a non-wood fibre source for paper production. Namely, triticale straw was converted into semi-chemical pulp and was combined with recycled wood pulp in order to produce alternative laboratory papers. The usability of this kind of laboratory papers in printing industry was analysed based on line reproduction quality. This research evaluated and analysed line reproduction quality based on four line attributes: width, blurriness and raggedness. The results of this research proved that triticale pulp in laboratory papers has equal influence on line printing quality as the recycled wood pulp.
The evolution of Romanian agritourism and the role of European Union
subsidies in rural areas
Authors: Galluzzo Nicola 
Published: May 2020

Abstract
Following the collapse of the communist regime in Romania, there has been an intense
growth in the number of farms providing holiday accommodation, which has gone to
answer the tourism flows from other European countries that have increased
significantly, particularly since 2009. The core purpose of this study was to
estimate, through a quantitative approach, the main relationships between decoupled
payments and other financial subsidies allocated by the European Union in the
framework of the Common Agricultural Policy (CAP) and the growth of Romanian
agritourism. The findings reveal that, over the 2007–2016 period, decoupled
payments more than financial subsidies allocated under the second pillar of the CAP
have acted to encourage the growth of agritourism in the Romanian countryside. This
has corroborated the crucial role that direct payments and other financial subsidies
have played in stimulating diversification in Romanian farms and, at the same time,
reducing the levels of permanent emigration from rural villages as well.
Inter-Ethnic Dynamics in the Wake of Terrorist Attacks: Evidence from the 2015 Baga Massacre
Authors: Belmonte Alessandro 
Published: May 2020

AbstractThis paper investigates the consequences for inter-group conflicts of terrorist attacks. I study the 2015 Baga massacre, a large scale attack conducted by Boko Haram at the far North-East state of Borno, Nigeria, as a quasi-natural experiment and examine a set of attitudes in the aftermath of the event of Christians and Muslims throughout the country. Comparing individuals, outside the region of Borno, interviewed by Afrobarometer immediately after the massacre and those interviewed the days before within same regions and holding fixed a number of individual characteristics, I document that the informational exposure to the event rendered Christians less amiable to neighboring Muslims and Muslims less likely to recognize the legitimacy of the state. Nonetheless, Muslims increased their view of the elections as a device to remove leaders in office, event that took place 2 months later with the election of the challenger, Muhammadu Buhari. My findings indicate that terrorist attacks may generate a relevant and heterogeneous backlash across ethnic groups.
Supposing the Law: Nomos and Categorical Imperatives in Never Let Me Go
Authors: Volpone Annalisa 
Published: May 2020

Abstract
This paper addresses the issue of posthuman bodies in Kazuo Ishiguro’s novel Never Let Me Go against the background of organ transplants and prosthetic surgery. The novel posits a number of questions about what qualifies a human being and/or what distinguishes a human being from a clone, suggesting that art, perhaps, might be a discriminating factor. Further, it also raises questions about the kind of regulation should be applied to organs “donations,” especially when they are not voluntary, but part of a programmed response inscribed in someone’s DNA. Accordingly, the last section of the paper will investigate the social impact of the exploitation of the clones and the medico-legal issues pertaining to it.
Digital Voodoo: Who Does What?
Authors: Carbone Paola , Rossi Giuseppe 
Published: May 2020

Abstract
It is obvious that AI is marking its entry onto the global scene. Anyway, since any AI is supposed to perform a task in such a way that the outcome would be indistinguishable from the outcome of a human agent working to achieve the same task, it is more and more difficult to recognize its presence in our daily life. Issues of transparency and ethics are crucial not only to be aware of the presence of an AI, but mostly to know how the algorithm is actually working and to verify the ‘quality’ of its dataset. It is important to realize that only the engineers know what an AI does, even if it enacts actions in real life. For common people, and even for regulators, it may turn out to be a digital voodoo that goes far beyond their understanding. Who does what? That is the question.
The first part of the essay discusses the claims of “digital philosophy” (or “digital ontology”) under the light of legal analysis. The assumption that humankind and “intelligent” machines share the same digital/algorithmic ontology (as parts of an all-encompassing “digital universe”) could deprive the law of its ethical and emotional foundations. A sound regulation of both the circulation of digital information and AI requires adequate knowledge of technology (transparency) and the capacity to make ethical choices based on wide social consensus, in order to safeguard the fundamentally “human” nature of the law.
The second part of the essay is an inquiry into AI as a machine-writing system, that is into the capacity of an AI to produce literary texts. Three examples will be discussed and a comparison to electronic literature will be pointed out. What seems to be fundamental is the idea of a literary output stuck on the very moment of its generation (process of writing) which is conceived by the reader as an anaesthetic experience. More than creativity, it is the perception of creativity that rules such literary works. This literary production can make readers aware of the power of an underlying algorithm.

Published: May 2020

AbstractBackgroundAn effective treatment strategy for peritoneal metastasis (PM) of hepatocellular carcinoma (HCC-PM) has yet to be established. Although cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have shown favorable outcomes in certain malignancies, their role in peritoneal metastatic HCC is unclear. Herein, we present a series of patients with HCC-PM treated with CRS/HIPEC and evaluate their outcomes.MethodsRecords of patients with HCC-PM who had undergone CRS/HIPEC at the Hyperthermia Center of Yuan’s General Hospital, Kaohsiung, Taiwan, between September 2015 and December 2016 were reviewed retrospectively. Patients were followed up until September 2019. We assessed the clinical courses and outcomes of these patients to clarify the benefits of CRS/HIPEC.ResultsSix patients were included in our study. HCC-PM occurred synchronously in one patient and occurred metachronously in five patients after therapeutic minimally invasive procedures, including radiofrequency ablation, laparoscopic hepatectomy, robotic hepatectomy or spontaneously. The median peritoneal cancer index was 18.5. All patients experienced complete peritoneal cytoreduction without perioperative mortality. One patient had two CTCAE grade 3 complications. The median follow-up was 16 months. The median overall survival was 15.7 months. Four patients died of lung metastasis or liver failure owing to intrahepatic recurrence. The survival rates observed at 1, 2, and 4 years were 66.7%, 33.3%, and 33.3%, respectively.ConclusionsCRS followed by HIPEC is feasible in patients with HCC-PM and might provide selected patients a chance for local disease control and longer survival. CRS/HIPEC might be considered as a treatment option in highly selected patients, as part of multimodal therapy approaches.
Electro-membrane separations in biotechnology

Published: May 2020

Abstract
Membrane processes are of crucial importance for downstream processing in biotechnology. This is due to their selectivity and the mild operating conditions, enabling to extract target products without damages caused by overheating and chemical agents. Besides the most spread membrane processes like ultrafiltration and reverse osmosis, electrodialysis is very important for removal and extraction of electrically charged products, i. e. anions of organic acids, some antibiotics, etc. The electrodialysis process can be organized in batch or continuous mode. On the other hand, in the electro-crossflow filtration, the transport of target solutes across the membrane is guided by two main driving forces, the transmembrane pressure and the electric potential. This combination enables various possibilities for more selective and efficient downstream processing in biotechnology. This chapter provides a brief overview of recent achievements of electrodialysis in selected bioproducts separations and recovery. A special focus, including original experimental data, is then given to electro-filtration, which is a powerful tool creating new opportunities for performing separations on the basis of both electric charge and particle size differences.

Case studies on computer-based identification of natural products as lead molecules
Authors: Simoben Conrad V. , Ntie-Kang Fidele , Robaa Dina , Sippl Wolfgang 
Published: May 2020

AbstractThe development and application of computer-aided drug design/discovery (CADD) techniques (such as structured-base virtual screening, ligand-based virtual screening and neural networks approaches) are on the point of disintermediation in the pharmaceutical drug discovery processes. The application of these CADD methods are standing out positively as compared to other experimental approaches in the identification of hits. In order to venture into new chemical spaces, research groups are exploring natural products (NPs) for the search and identification of new hits and more efficient leads as well as the repurposing of approved NPs. The chemical space of NPs is continuously increasing as a result of millions of years of evolution of species and these data are mainly stored in the form of databases providing access to scientists around the world to conduct studies using them. Investigation of these NP databases with the help of CADD methodologies in combination with experimental validation techniques is essential to identify and propose new drug molecules. In this chapter, we highlight the importance of the chemical diversity of NPs as a source for potential drugs as well as some of the success stories of NP-derived candidates against important therapeutic targets. The focus is on studies that applied a healthy dose of the emerging CADD methodologies (structure-based, ligand-based and machine learning).

Bio-pulping: An energy saving and environment-friendly approach
Authors: Kumar Amit , Gautam Archana , Dutt Dharm 
Published: May 2020

AbstractPretreatment of wood or other raw material with white-rot fungi (WRF) prior to pulping is known as biopulping. Lignin and hemicelluloses are removed selectively during early growth of WRF that produces enriched cellulose, known as selective delignification. Biopulping is considered as environment-friendly and cost-effective approach for delignification of lignocellulosic raw materials. The delignification efficiency of WRF during biopulping is directly related to ligninolytic enzymes production that is influence by several factors such as fungal strain, nature of raw material, oxygen availability, moisture content, pH, temperature, source of nitrogen, presence of Mn++and Cu++ions. The WRF, especiallyCeriporiopsis subvermispora,Trametes versicolorandPhanerochaete chrysosporium, have been used dominantly for the purpose of biopulping. It is an energy saving process that also improves brightness of pulp and strength properties including tensile index, burst index and folding endurance of paper. Significant decrease in kappa number has also been attained by fungal pretreatment of raw materials. Biological pretreatment of raw material also reduces the requirement of pulping chemicals.
