Published: February 2021

The characterization of the prebiotic potential of legumes and mucilage are essential and crucial for the development of symbiotic food products. The aim of the present study was to compare and to determine the prebiotic capacity of selected legumes, namely adzuki bean, mung bean, black cowpea, and mucilages from chia seed and flaxseed on the growth of Lactobacillus rhamnosus GG. Resistance towards acid, pancreatin hydrolysis, and the prebiotic scores of the tested substances was determined based on growth promotion after 24 h of incubation. Results revealed that flaxseed mucilage was more resistant against hydrolysis by acid (1.47%) and pancreatin (2.64%) compared to the other samples (5.64 – 18.06% for acid and 10.34 – 15.57% for pancreatin). The relative prebiotic scores for flaxseed mucilage and black cowpea were 98% and 94%, respectively, which were higher than commercial prebiotics including inulin, fructooligosaccharides, and isomaltooligosaccharides. The optimum concentrations of flaxseed mucilage and black cowpea during 36 h of fermentation were 0.8% and 0.4% (w/v), respectively. The findings indicated that flaxseed mucilage was partially digested during gastrointestinal transit and it promotes the growth of the L. rhamnosus GG. The potential prebiotic capacity of flaxseed mucilage and its symbiotic relationship with L. rhamnosus GG suggests that they can be incorporated together for the development of functional foods.

Authors: Cartwright Chris , Stevens Michael , Schneider Katharina
Published: February 2021

Constructing the learning outcomes and designing the optimal learning environment are valuable practices in teaching and learning endeavors. Doing so for intercultural learning requires a deft balance of learner inputs and instructional acumen. Assessment of intercultural competence is an essential component since it offers learners and instructors insights on where students are, where they wish to grow, and the success of treatment outcomes. In this study of practice, we examine three years of pre-post mixed-method intercultural assessment data, along with teaching and learning practices and outcomes, to gain insights into how this work of instructional design for intercultural competence can succeed. We also provide suggestions for improvements. The learners were 203 MBA students from the U.S. Pacific Northwest who were enrolled in either a short-term study abroad program or a “glocal” learning experience course. Learners were assessed using the Inter cultural Effectiveness Scale (IES) and the AAC&U VALUE Rubric on Intercultural Knowledge and Competency (IKAC). Results support the criticality of intentional instructional course design based on intercultural assessment data for improved intercultural competency development.

The explosion of information and the ever-increasing number of international languages make the modern language situation very difficult. The interaction of languages ultimately leads to the creation of international artificial languages that operate in parallel with the world`s languages. The expansion of interlinguistic issues is a natural consequence of the aggravation of the linguistic landscape of the modern world. The modern interlinguistic dialect, which is defined as a field of linguistics that studies international languages and international languages as a means of communication, deals with the importance of overcoming the barrier.The problem of international artificial languages is widely covered in the writings of I.A.Baudouin de Courtenay, V.P.Qrigorev, N.L.Gudskov, E.K.Drezen, A.D.Dulchenko, M.I.Isayev, S.N.Kuznechov, A.D.Melnikov and many other scientists.

The use of modern therapeutic agents for the treatment of intestinal parasitoses makes it possible to successfully deworm them. It should be borne in mind that these therapeutic agents do not give guaranteed results after applying only a single course of therapy. After a single use of the course of therapy, the effectiveness in most cases is only 90%, and with repeated courses of therapy a complete cure for helminthiasis is achieved. The effectiveness of deworming is taken into account according to two criteria: a radical (or complete) cure and a decrease in the intensity of the lesion. If it is impossible to prevent repeated cases of transmission of helminthiases in endemic foci of invasion, questions of complete eradication from parasitoses are not considered. In such cases, individual control tactics are developed for this outbreak, with the identification of groups and risk factors, the presence of those affected with a high level of invasion.

The role of interleukin-24 in atopic dermatitis
Authors: Vu Yen Hai , Furue Masutaka , Tsuji Gaku
Published: February 2021

Atopic dermatitis (AD) is characterized by skin barrier disruption, type 2 immune dysregulation, chronic pruritus, and abnormal colonization by Staphylococcus aureus (S. aureus). Tapinarof, an aryl hydrocarbon receptor modulator, has been demonstrated to attenuate the development of AD in clinical studies. Recently, we found that tapinarof upregulated the expression of filaggrin and loricrin, which are essential proteins in skin barrier functions. Paradoxically, tapinarof induced interleukin (IL)-24 secretion by normal human keratinocytes. IL-24 is produced by T helper 2 lymphocytes and keratinocytes following stimulation by type 2 cytokines, and IL-24 is upregulated in the skin of patients with AD. Furthermore, IL-24 contributes to skin barrier disruption and hyperplasia in AD, and it may exacerbate skin inflammatory responses, itch, and S. aureus infection. In this review, we summarized the current findings regarding the detrimental role of IL-24 in AD, thereby suggesting that co-treatment of tapinarof with therapeutics that block IL-24 signaling may represent a promising strategy for managing AD.
Aptamers and antibodies: rivals or allies in cancer targeted therapy?
Authors: Agnello Lisa , Camorani Simona , Fedele Monica , Cerchia Laura
Published: February 2021

The goal of an efficacious cancer therapy is to specifically target diseased cells at high accuracy while sparing normal, healthy cells. Over the past three decades, immunotherapy, based on the use of monoclonal antibodies (mAbs) directed against tumor-associated antigens, to inhibit their oncogenic function, or against immune checkpoints, to modulate specific T cell responses against cancer, has proven to be an important strategy for cancer therapy. Nevertheless, the number of mAbs approved for clinical use is still limited because of significant drawbacks to their applicability. Oligonucleotide aptamers, similarly to antibodies, form high-affinity bonds with their specific protein targets, thus representing an effective tool for active cancer targeting. Compared to antibodies, aptamers’ use as therapeutic agents benefits from their low size, low/no immunogenicity, simple synthesis and design flexibility for improving efficacy and stability. This review intends to highlight recently emerged applications of aptamers as recognition elements, from biomarker discovery to targeted drug delivery and targeted treatment, showing aptamers’ potential to work in conjunction with antibodies for attacking cancer from multiple flanks.

Authors: Shamsuzzaman Md. , Abdul Awal Ziad , Das Dip
Published: February 2021

This paper investigates the changes in the properties of denim garments with respect to laser intensities of different DPI and Pixel Time. The laser added value to denim garments can fade the outer surface and the yarn portion significantly. In this research, DPI 20 and 25 along with Pixel Time 100, 150 and 200 were applied on samples to investigate the fabric weight, absorbency, crease recovery, tear resistance, tensile strength, pilling and abrasion resistance. For each of the cases, increased DPI and Pixel Time had much greater impact than other parameters on the denim garment samples. After treatment, the fabric sample indicated around 10-30% in weight reduction. The absorbency property of the sample on the other hand showed that higher DPI and Pixel Time required less time to absorb the water on the fabric surface. Furthermore, fabric crease recovery property reduced sharply where maximum 33% crease could not recover after laser exposure. For both tear resistance and tensile strength, especially warp way direction, property reduced more compared to weft way direction due to higher fading effects. After 12,000 cycles, both pilling and abrasion resistance property demonstrated significant reduction for higher laser intensities.

Published: February 2021

The main objective of the current work is to investigate the influence of reaction temperature on catalytic pyrolysis of High-Density Polyurethane (HDPE) over Ni/Ce/Al2O3 into enriched hydrocarbons of pyrolytic oil and gas The experiments were performed at four different pyrolysis reaction temperatures (500, 600, 700, and 800 °C) via in-situ fixed bed reactor. The Al2O3 (75 wt.%) was used as a support, while nickel (20 wt.%) and cerium (5 wt.%) were impregnated as promoters via incipient wetness impregnation method. The catalyst to plastic mass ratio was kept constant at 1:1 for all investigated samples. The results revealed that the Ni/Ce/Al2O3 catalyst has synergistic effects on the catalytic pyrolysis of HDPE into a high yield of hydrocarbon compounds (C5 – C20) in pyrolytic oil and hydrogen gas composition in pyrolytic gas. The highest yield of pyrolytic oil was achieved at 700 °C (53.23 %), while the highest yield of pyrolytic gas was achieved at 800 °C (67.85 %). The small molecular hydrocarbons in pyrolytic oil (C5 - C9) decreases with increasing temperature from 500 to 800 °C. The highest hydrogen gas yield of 77.59 %. was achieved at 700 °C. Thus, this research has economic feasibility in producing alternative valuable energy from the plastic waste stream.

A critical analysis of the competition authorities’ treatment of the element of causation in exclusionary abuse cases
Authors: Radebe Sibusiso
Published: February 2021

It is trite law that in order for an impugned act to be condemned in terms of the exclusionary abuse prohibition, entrenched under the Competition Act 89 of 1998, there must be evidence evincing that the said act caused some anti-competitive effect and that the anti-competitive effect caused by the said act outweighs any procompetitive effect caused by it. This position makes the element of causation of central importance in the determination of whether or not to condemn an impugned act in terms of the exclusionary abuse prohibition. However, despite the pivotal role played by causation in the resolution of exclusionary abuse cases, the competition authorities have repeatedly neglected to, inter alia, expound the framework of causation envisaged under the exclusionary abuse prohibition and state the legal principles upon which their conclusions of causation are based. This neglect has caused some competition law commentators to argue that the competition authorities have failed to assess the element of causation in exclusionary abuse cases. This paper examines exclusionary abuse case law through the lens of the common-law framework and tests for assessing causation and demonstrates that, despite the criticism levelled against the competition authorities, first, the authorities do in fact have a framework of causation and tests for assessing causation; secondly, the authorities have been employing the framework referred to above consistently since its first appearance in the case law; and thirdly, the said framework is consistent with the framework of causation envisaged, or apparently envisaged, under the exclusionary abuse prohibition entrenched in the Competition Act 89 of 1998.
Protecting taxpayer information from the public protector – A ‘just cause’?
Authors: Moosa Fareed
Published: February 2021

Under the Tax Administration Act, 2011 (TAA), taxpayers enjoy a right to privacy of information disclosed to the South African Revenue Service (SARS). This note shows that tax officials are obliged to protect the secrecy thereof. It is argued that the Commissioner for the SARS correctly resisted compliance with a subpoena issued by the Public Protector for access to the records of former President Jacob Zuma. If it acquiesced without objection, shock waves would have reverberated through South Africa’s tax community. It is contended that the Commissioner’s decision to maintain taxpayer secrecy under pain of a potential criminal sanction contributed to restoring some of the lost confidence and respect for the SARS which has, in recent times, endured reputational damage owing to internal squabbles which morphed into public scandals. This note hypothesises that CSARS v Public Protector is good authority for the proposition that governmental departments and state institutions not expressly mentioned in s 70 of the TAA do not have statutory rights of access to taxpayer information and must, to gain access, follow due process. This note argues that the judgment in casu is not only a victory for taxpayer rights but also for the rule of law.

AUTOMATIC MICROINJECTION SYSTEM USING STEREOSCOPIC MICROSCOPE
Authors: Sakiyama Junko , Yamamoto Hideki
Published: February 2021

In this paper, we describe a visual feedback system using a stereoscopic microscope that controls a micromanipulator so that a needle head may pierce a target as much length as desired. At first, we developed an image processing algorithm for the tip of needle head to touch the target. Secondarily, we developed an algorithm for prediction of the tip position of the needle head within the target. By performing a preoperation, the shape of the needle head is preserved as a reference pattern. When the needle head piercing the target, the shape of the needle head within the target is predicted by pattern matching. Thus, we developed a microinjection system that axially pierces the target. Experimental results show that the proposed system may be useful in micromanipulation such as microinjection to brain areas in neuroanatomy.

UNSUPERVISED TEXTURE CLASSIFICATION OF ENTROPY BASED LOCAL DESCRIPTOR USING K-MEANS CLUSTERING ALGORITHM
Authors: Sreeja Mole S. S. , Ganesan L.
Published: February 2021

This paper presents an efficient approach for unsupervised Texture Segmentation and Classification, based on features extracted from entropy based local descriptor using K-means clustering with spatial information. The K- means clustering algorithm is commonly used in computer vision as a form of image segmentation. Texture analysis refers to a class of mathematical procedures and models that characterizes the spatial variations within imagery as a means of extracting information. Texture analysis may require the solution of two different problems first is Segmentation and Classification of a given image according to the different texture and second was for of a given texture with respect to a set of known textures. Based on the proposed concept, this paper describes the entropy based local descriptor using K-Means with spatial information approach. Experimental results show that the proposed framework performs very well compared to other clustering algorithms in all measured criteria. Spatial information has been effectively used for unsupervised texture classification for Brodatz of texture images. The model is not specifically confined to a particular texture feature. We tested this algorithm using other texture features. The proposed entropy based local descriptor approach gives good accuracy when compared with other methods.

SBLWPR – SIMILARITY BASED LINK WEIGHT FOR PAGERANK CALCULATION
Authors: Poomagal S. , Hamsapriya T.
Published: February 2021

Search engine retrieves list of web pages which are relevant to the given query from the index and sorts the list based on the page importance score. There are different ranking algorithms available in the literature to calculate the importance score of web pages. The basis of all ranking algorithms is the link structure of the web. In existing ranking algorithms, no weight is assigned to the links by considering the similarity among the linked documents. Since links from similar documents are more important than the links from other dissimilar documents, a new method is introduced to assign weight to each link based on the similarity among the linked documents. Calculated link weight is added with existing PageRank value to calculate final PageRank. Proposed technique is compared with existing ranking algorithms using the measures precision, recall and F-measure.
MINGLING THE CONTEXTUAL INFORMATION IN IMPROVED MULTIDIMENSIONAL RECOMMENDATION SYSTEM
Authors: Husain Mohammad
Published: February 2021

Recommender systems utilize the times of yore experiences and preferences of the target customers as a basis to proffer personalized recommendations for them as well as resolve the information overloading hitch. Personalized recommendation methods are primarily classified into content-based recommendation approach and collaborative filtering recommendation approach. Both recommendation approaches have their own advantages, drawbacks and complementarities. Because conventional recommendation techniques don’t consider the contextual information, the real factor why a customer likes a specific product is unable to be understood. Therefore, in reality, it often causes a decrease in the accuracy of the recommendation results and also persuades the recommendation quality. In this paper, we propose the integrated contextual information as the foundation concept of multidimensional recommendation model and use the Online Analytical Processing (OLAP) ability of data warehousing to solve the contradicting tribulations among hierarchy ratings. This work hopes that by establishing additional user profiles and multidimensional analysis to find the key factors affecting user perceptions, it would increase the recommendation quality.

In wired Ethernet networks (IEEE 802.3), a physical network interface can be connected to different network segments or shared among multiple virtual machines. In wireless LAN (IEEE 802.11) sharing a wireless network interface is recognized to be a difficult task. However, virtualization can solve this problem. In this paper we will introduce a software platform for hosting multiple virtual wireless networks over a shared physical infrastructure by means of open source virtualization techniques. We present the design, implementation, and performance testing of this platform. Results have shown that the hosting platform can extend wireless networking into virtualized environments without compromising the performance, isolation, or wireless LAN security mechanisms.

Published: February 2021

One option for reducing carbon dioxide emissions is the future use of renewable instead of fossil resources. A consistent prerequisite is the optimization of household customers’ energy consumption behavior. The suitable visualization of energy data, corresponding costs and tariff information on mobile devices is essential to achieve this goal. Energy data are acquired by a smart meter and transferred over wireless networks to a mobile device to provide the customer with relevant information about his current energy usage. The household customer is hence enabled to manage his energy consumption, to hold the optimal load and meet the optimum price. Suitable typs of visualization, specific for different tariffs, are identified and presented together with necessary technologies and methods for communication and data access and delivery.

Authors: Strutu Mircea Ionel , Popescu Dan
Published: February 2021

This paper proposes the idea of a wireless sensor network with applicability in monitoring systems. The goal of the project is to build a monitoring system capable of data gathering which can benefit from both characteristics of fixed and mobile nodes. To become flexible, the mobile node has a modular structure with four levels. The flexibility offered by the mobile nodes increases the performance of the entire data acquisition system. These act as autonomous devices that cooperatively monitor physical or environmental conditions. In order to implement the data acquisition and communication functions, the solution we agreed on has been to use the MTS400 sensor board. Mobile nodes communicate to a central node individual data and statistical indicators over a period. The proposed energy-aware architecture was tested and validated in an indoor experiment.

Results of conducted simulations are presented and analyzed.
POST-CORRECTION OF ADC NON-LINEARITY USING INTEGRAL NON-LINEATITY CURVE
Authors: Haasz Vladimir , Slepicka David , Suchanek Petr
Published: February 2021

The accuracy of AD conversion can be improved usin g the post-correction of digitizer non-linearity. In principle two methods could be applied – look-up table or an analytical inverse function of integral non-linearity curve (INL(n)). Look-up table can be easily implemented but it demands huge memory space particularly for high resolution ADCs. Inverse function offers flexible solution for parameterization (e.g. frequency dependence) but it also requires fast DSP for real-time correction. The data or coefficients for bot h methods are frequently determined from a histogram of acquired pure sinusoidal signal. Non-linearity curve can also be gained by another procedure demanding significantly less samples – approximation from a frequency spectrum. The correction of ADC nonlinearity by means of inverse function of INL(n) curve is analyzed in this paper and the results are presented.

Authors: Kotenko Igor V. , Nesteruk Filipp G. , Shorov Andrey V.
Published: February 2021

The paper suggests the conception of a hybrid adaptive protection of information and telecommunication systems which is based on a biometaphor of nervous and neural networks. A top level of a protection system, based on an approach of “nervous system network” is a distributed mechanism for collecting and processing information. We suggest to implement the in formation processes on the low level with the assistance of an “information field” programming. It allows specifying the distributed information fields in the form of neural network software packages.

Authors: Petryshyn Lubomyr
Published: February 2021

The system of Walsh functions is the multiplicative group of Rademacher- and Gray-function systems. The system contains discrete-harmonic sin-components of Rademacher functions, cos-components of Gray functions, and also discrete-nonharmonic components of Walsh functions. Pair phase interdependence of complete Walsh system functions is established. Subsystems of odd (sin-components) and even (cos-components) of Walsh functions as bases of theoretic-number transformations are constructed. The perspective of the future researches of transformations efficiency for digital signal processing in the proposed function systems is defined.

ENHANCING THE COVERAGE OF INDOOR RADIO LOCALIZATION BY DISTRIBUTED COMPUTATIONS
Authors: Fink Andreas , Beikirch Helmut
Published: February 2021

The prevalent evaluation criterion for indoor local positioning systems (ILPS) is the achievable accuracy in terms of Euclidean distance between estimated and true position. Systems relying on received signal strength (RSS) ranging often use a distributed collection of RSS sensor data at reference nodes and a centralized position estimation. For this direct remote positioning, the accuracy is dependent on the reference node density and thus, is indirect proportional to the achievable coverage. To split up the dependency between these two criteria, we propose a distributed weighted centroid localization (dWCL) strategy with a hierarchical sensor data field bus. Accuracy and coverage of centralized and distributed WCL algorithms are compared for a one-dimensional tracking simulation and 196 reference nodes, arranged in up to 28 gateway segments. Using distributed computations, the localization system’s coverage is increased by factor ten while the location estimation error increases only slightly.
BREAKING BLOCK AND PRODUCT CIPHERS
Authors: Carlson Albert H. , Hiromoto Robert E. , Wells Richard B.
Published: February 2021

The security of block and product ciphers is considered using a set theoretic estimation (STE) approach to decryption. Known-ciphertext attacks are studied using permutation (P) and substitution (S) keys. The blocks are formed from two (2) alphabetic characters (meta-characters) where the applications of P and S upon the ASCII byte representation of each of the two characters are allowed to cross byte boundaries. The application of STE forgoes the need to employ chosen-plaintext or known-plaintext attacks.

Published: February 2021

Systolic tree structure is a reconfigurable architecture in Field-programmable gate arrays (FPGA) which provide performance advantages. It is used for frequent pattern mining operations. High throughput and cost effective performance are the highlights of the systolic tree based reconfigurable architecture. Frequent pattern mining algorithms are used to find frequently occurring item sets in databases. However, space and computational time requirements are very high in frequent pattern mining algorithms. In the proposed system, systolic tree based hardware mechanism is employed with Weighted Association Rule Mining (WARM) for frequent item set extraction process of the Web access logs. Weighted rule mining is to mine the items which are assigned with weights based on user’s interest and the importance of the items. In the proposed system, weights are assigned automatically to Web pages that are visited by the users. Hence, systolic tree based rule mining scheme is enhanced for WARM process, which fetches the frequently accessed Web pages with weight values. The dynamic Web page weight assignment scheme uses the page request count and span time values. The proposed system improves the weight estimation process with span time, request count and access sequence details. The user interest based page weight is used to extract the frequent item sets. The proposed system will also improve the mining efficiency on sparse patterns. The goal is to drive the mining focus to those significant relationships involving items with significant weights.
