Authors: Nguyen Lan Thi Phuong , Kalabeke Wisdom , Muthaiyah Saravanan , Cheng Ming Yu , Hui Kwan Jing , Mohamed Hazik
Published: October 2021

Background - With the recent evolution of Financial Technology (FinTech), 11 peers to peer (P2P) lending platforms have been regulated by the Securities Commission in Malaysia since 2016. P2P lending platforms offer new investment opportunities to individual investors to earn higher rates on return than what traditional lenders usually provide. However, individual investors may face higher potential risks of default from their borrowers. Therefore, individual investors need to understand the potential exposure to such P2P lending platforms to make an effective investment decision. This study aims to explore the potential risk exposures that individual investors may experience at Malaysia's licensed P2P lending platforms.  

Methods - Based on data collected manually from nine P2P lending platforms over five months, relationships between interest rates and various risk classifying factors such as credit rating, industry, business stage, loan purpose, and loan duration are examined.  

 Results- This study shows that loans with a similar credit rating and with or without similar loan purpose; and a business stage may offer investors significantly different interest rates. In addition, loans with shorter durations may provide investors with higher interest rates than those with longer durations. Finally, loans issued by companies from the same industry appeared to be charged with similar interest. These findings are valuable to investors to prepare themselves before making their investments at the P2P lending platforms.  

Conclusion- With first hand-collected data, this study provides an original insight into Malaysia's current P2P lending platforms. Findings obtained for relationships between interest rates and risk classifying factors such as credit rating, industry, business stage, loan purpose and loan duration are valuable to investors of Malaysian P2P lending platforms.

El poder de la creación de imágenes sonoras: cómo la radio contó la crisis del euro.
Authors: Colmenarejo Juan Pablo , Martínez Costa María del Pilar
Published: October 2021

La radio es un medio que dispone exclusivamente del sonido y de la construcción de imágenes sonoras para elaborar sus mensajes. Lo hace desplegando una variedad de recursos lingüísticos, con un alto poder evocador. Mediante la construcción de metáforas conceptuales, que permiten concretar nociones abstractas, la radio consigue explicar y mostrar la realidad, a través de representaciones sonoras de la vida cotidiana de sus oyentes. Cuanto más complejo es el tema de la actualidad, la radio recurre con más frecuencia a las metáforas conceptuales —mediante la acumulación de recursos y la redundancia— para recrear las imágenes que lo expliquen. El objetivo de este trabajo es describir y caracterizar cómo la radio informó de la crisis del euro a través de la creación de imágenes sonoras. Desde una aproximación cuantitativa y cualitativa, se analiza la construcción de la metáfora conceptual ‘La crisis es una guerra’ en la tertulia El equipo económico de La linterna de la Cadena COPE de mayo de 2010 a julio de 2012, período central de la crisis del euro en España. En la construcción de dicha metáfora conceptual y las imágenes sonoras asociadas se estudian los atributos y conceptos adjudicados a la expresión “rescate”, cuya explicación fue importante para mostrar la evolución de la crisis, primero como una “operación de salvamento”, y luego como una “invasión”. El estudio concluye que la forma de contar de la radio, recurriendo a imágenes próximas al oyente, refuerza su poder informativo para explicar una realidad compleja.

A scalable, multi-wavelength, broad bandwidth frequency-domain near-infrared spectroscopy platform for real-time quantitative tissue optical imaging
Authors: Stillwell Roy A. , Kitsmiller Vincent J. , Wei Alicia Y. , Chong Alyssa , Senn Lyla , O’Sullivan Thomas D.
Published: October 2021

Frequency-domain near-infrared spectroscopy (FD-NIRS) provides quantitative noninvasive measurements of tissue optical absorption and scattering, as well as a safe and accurate method for characterizing tissue composition and metabolism. However, the poor scalability and high complexity of most FD-NIRS systems assembled to date have contributed to its limited clinical impact. To address these shortcomings, we present a scalable, digital-based FD-NIRS platform capable of measuring optical properties and tissue chromophore concentrations in real-time. The system provides single-channel FD-NIRS amplitude/phase, optical property, and chromophore data at a maximum display rate of 36.6 kHz, 17.9 kHz, and 10.2 kHz, respectively, and can be scaled to multiple channels as well as integrated into a handheld format. The entire system is enabled by several innovations including an ultra-high-speed k-nearest neighbor lookup table method (maximum of 250,000 inversions/s for a large 2500x700 table of absorption and reduced scattering coefficients), embedded FPGA and CPU high-speed co-processing, and high-speed data transfer (due to on-board processing). We show that our 6-wavelength, broad modulation bandwidth (1-400 MHz) system can be used to perform 2D high-density spatial mapping of optical properties and high speed quantification of hemodynamics.
A review of Fasciolopsis buski distribution and control in Indonesia
Authors: Ridha Muhammad Rasyid , Indriyati Liestiana , Andiarsa Dicky , Wardhana April Hari
Published: October 2021

Fasciolopsiasis is a parasitic infection caused by the flatworm Fasciolopsis buski. Since 1982, fasciolopsiasis has been reported in Indonesia's Hulu Sungai Utara (HSU) Regency, South Kalimantan Province. Fasciolopsiasis occurs when contaminated raw or undercooked aquatic plants are consumed. Cercariae of the parasite encyst in a variety of aquatic plants and grow into metacercariae that infect and reproduce in the human intestine. Until now, treatment for F. buski infection in the HSU Regency has been comparatively short, with patients receiving only a single dose of praziquantel, 30 mg/kg body weight, without further observation. A long-term effort through health promotion activities and intensive health education, particularly for elementary school children enrolled in the School Health Program, is ongoing to help prevent fasciolopsiasis from spreading and to improve environmental sanitation. Through 2018, intervention efforts successfully reduced the incidence of F. buski infection. Sustaining surveillance and investigation of fasciolopsiasis, including identification of new cases and community education, is critical for the elimination of the parasite from Indonesia. This review describes the spread of F. buski and its possible impact on public health to understand the critical nature of continuing F. buski surveillance and control efforts.

The article assesses the richness of the collection fund of Siberian plants that grew in the historical periodfrom 1954 to 1963 and grow in the modern period from 2011 to 2020 in the collection “Alpine Slides” of the Peter the GreatBotanical Garden. The main purpose of this article was to assess the preservation of the collection fund of Siberian andpartly Central Asian plants in the historical aspect. It was necessary to identify the plant species that are most resistant tocultivation in the conditions of St. Petersburg. As a result of the comparison, it was found that at present the collection fundof plants is quite poor, compared to the selected historical segment, and it needs to be replenished. The most stable in thecollection were 22 species, as they existed in the collection both in the selected time periods and exist at the present time.The age of individuals of individual species reaches almost 80 years – Brunnera sibirica, Bergenia × ornata, Actaea dahurica,A. simicifuga, Nepeta sibirica, Spodiopogon sibiricus and others. In the modern period of time, more than 20 species didnot pass the initial introduction test and existed in the collection for no more than 2–3 years. These include Viola altaica,Mertensia sibirica, Peucedanum baicalense, Orostachys thyrsiflora and others.

The purpose of the current study was to identify the species indicators of the communities of the ChernayaRiver and to assess the water quality by bioindication methods. During the summer field trips in 2019–2020 on the territoryof the Zhongar–Alatau Natural State Reserve within the framework of the special purpose funding program № BR05236546“Implementation by the state botanical gardens of the priority scientific and practical tasks of the global strategy for plantconservation as a sustainable system for maintaining biodiversity” (head, Dr. G. T. Sitpayeva). In the course of the study,algae were sampled from the Chernaya River, and their species composition was studied A total of 94 species and varietiesof algae from four divisions were found. Analysis of indicator types by water properties: temperature, oxygen saturation,organic pollution, salinity, trophic state of water and the type of nutrition of algae species has been revealed. This was thefirst experience of implementing a bioindication approach to the environmental assessment of the water quality of thisriver. The most significant types of diatoms strongly predominated in different studied places of the river. It was revealedthat the algae species can characterize the composition of the river as slightly alkaline, slightly saline, moderate, medium –acidified water with low organic pollution. Algae communities are mainly represented by benthic and planktonic – benthicautotrophic species. Statistical analysis of species – mediated relationships has shown that most species prefer to survive incommunities with complex structures formed in poorly polluted organic waters.

Karyological studies of Siberian species of the genus Viola L.
Authors: Elisafenko T. V.
Published: October 2021

The article presents an analysis of chromosome numbers in Siberian species of the genus Viola (40 speciesfrom 12 sections) based on numerous literary sources and original data. In addition, hybrid forms from the collection site“Rare and endangered Plant Species” of the Central Siberian Botanical Garden (Novosibirsk) were analyzed. Just as theroots of germinated seeds, so the roots of adult plants from an open ground area were studied. Samples of different originswere investigated: Siberia, the Far East, Mongolia, Belarus, Korea, Japan, the Caucasus, in some taxa from remote points ofthe area (for example, V. selkirkii). This allowed us to reveal the variability of the chromosome numbers for some species.Chromosomes in species of this genus are small, 0.8–1.2 mkm long. This involves difficulties to count them. The presenceof mixoploids in some sections and the polybasic state of chromosome numbers for a number of species were established.Polymorphic species in the Violidum section are characterized by polyploid races. The variability of chromosome numbersin taxa reflects their ability to hybridize, as well as the processes of speciation. However, the predominance of autogamy formost species of the genus prevents intensive hybridization. Endemic and tertiary relicts are characterized by a stable number of chromosomes and they are tetraploids.

Authors: Kutenkov S. A. , Tarasova V. N.
Published: October 2021

The paludified herb-rich spruce forests of the Pinego-Mezen watershed are characterized by a high speciesand coenotical diversity. The habitat type (floodplain, stream valley, mire margin) is the main compositional gradientfor vascular plant and moss diversity. The density, basal area and proportion of spruce and deciduous species in thetree stand are less significant. The main compositional gradient of the lichen diversity is the tree stand structure, whichprovides the availability and quality of the substrate for the epiphytic and epixilic lichens that prevail in such communities.The gradient of paludified herb-rich spruce forests from floodplain habitat to mire margins is less significant for thecomposition of lichen flora.
About some discussion issues on steppe typology and florocenotypes related to them in vegetation of South Siberia
Authors: Namzalov B. B.
Published: October 2021

The phytogeographic ecotonicity of Southern Siberia (SS) is reflected in the features of its flora and vegetation, in particular the steppes. The recognition of only a floristic criterion in the typology of vegetation impoverishestheir real cenotic diversity. It is necessary to accept the florocenogenetic concept with fractional landscape-biomorphological types – florocoenotypes in the spirit of P. N. Ovchinnikov. By the genesis, the most ancient are the zonal sod grass(feather grass) steppes. However, the initial should be considered the Achnatherums and, in general, the communities ofshort-awned great-feather grass (Tsvelev, 1977), which formed steppe groups in the Tertiary savannoid complexes. Theformation of mountain cereal steppes – with fescue, oat, bluegrass, etc. took place synchronously with cryoxerophytization, starting from the Oligocene. The originality of the SS steppes is given by some rare steppe communities, which arecoenogenetically close to the tragacanth, friganoid, shiblyak and ephemeral steppes of mountainous Central Asia. Theseare distinctive relict steppes in the belt of the Altai, Sayan and Transbaikal mountains, which include communities of viviparous grassland steppes in the foothills of Western Altai, tragacanth-oxytropis steppes of southeastern Altai, and communities of the Tuvan and Daurian shiblyak, as well as groups of Altai friganoids with Ziziphora clinopodioides, Thymusaltaicus and Allium pallasii.

Published: October 2021

The collection of rare species in the botanical garden of Almaty (Kazakhstan) consists of 36 species of rareplants. The Botanical garden is located in the foothill zone of the Zailiysky Alatau ridge, which is part of the Northern TienShan mountain system. A collection of rare and endemic species from the mountainous regions of the Northern, Western Tien Shan, and the Kazakh Altai was created, but most of their work was carried out in the mountains of the NorthernTien Shan. The largest species composition of the collection are groups of plants of the genera Tulipa – 25 %, Iris –14 %,Allium – 8.3 %. The largest ecological group in the collection of rare species is represented by ephemeroid geophytes. Introduction tests have shown that ephemeroid drought-resistant plants adapt best to the conditions of the foothill zone of theTrans-Ili Alatau. Xerophyte plants are short-lived, often suffer from the accumulation of snow in winter and the abundance of spring precipitation. Mesophytic plants are prone to drying out from lack of humidity and high air temperaturesin the summer.

Published: October 2021

For research the plants of Malaxis monophyllos (L.) Sw. were sampled in the Amur region and takenfrom the herbarium collections of the same region (MW and MHA). The plants of M. monophyllos have a high degreeof vari-ability of quantitative morphological characters. First, we paid attention to the number of leaves, the height ofplants and peduncles, the number and size of leaves and the number of flowers. Therefore, the purpose of this workwas compara-tive molecular studies of individuals of the same species with different morphological characteristics.Internal transcribed spacers (ITS1 and ITS2) of the 18S–26S region of nuclear ribosomal DNA were chosen as amolecular marker. On the molecular phylogenetic tree, the analyzed M. monophyllos plants form clade with a highposterior probability (1.0). The ITS sequences of the analyzed samples are not identical. The level of geneticdifferentiation of nucleotide sequences was 0.12 %, which corresponds to the variability within the species, whichconfirms the belonging of the analyzed samples to the same species. Since the species has a large area, it is necessary toanalyze plant samples from other regions to obtain reliable results. The different regions of the nuclear and plastidgenomes should be added to the genetic analysis.

It is shown that the efficiency of the development of ecological space is the highest in terms of climate continentality and thermoclimatic factors, the lowest in termsof soil moisture and acidity, ombroclimatic aridity-humidity. The ontogenetic spectra are uniform over the years: the maximum fall on individuals of the juvenile, virginal and subsenile ontogenetic states, and the minimum is on the plants ofthe generative period in aggregate. According to the «delta-omega» classification, the studied coenopopulation undergoesdevelopment from young to transitional.
Environmental assessment of Petasites spurius (Retz.) Reichb. in various habitats of the southern taiga subzone in Kirov oblast
Authors: Shakleina M. N.
Published: October 2021

The paper presents the results of an ecological assessment of Petasites spurius habitats in the southern taigasubzone of Kirov oblast. Indicators of potential ecological valence indicate a low degree of lability of species individuals,which is manifested in the predominance of stenovalent and hemistenovalent fractions. Their distribution is limited by verydry and damp, poor and saline soils, low illumination. The studied P. spurius cenopopulations differ in the level of soilmoisture and salt regime, which is associated with the degree of their distance from the water line. In general, individuals of P.spurius quite fully realize their ecological potential, however, in cenopopulation 1 they are realized the least. This is due to itslocation, high level of moistening, surface occurrence of water table and constant leaching of mineral salts from the substrate.

Vegetation degradation was mostly observed in river valleys, lowerplains, hills and small mountains and mountain slopes due to the intensity of summer grazing. The moderately degraded areawas often winter places using as rotate or properly managed grazing land and light degradation has occurred in the forest area.Very strong degradation was revealed mainly in Saikhan, Orkhon, Javkhlant sub-provinces and strongly degraded in Sant,Orkhontuul, Baruunburen. Light degradation of vegetation were observed in sub-provinces adequately covered by forestincluding Eruu, Tushig, Shaamar, Khuder, but there are still problems related to mining and deforestation.
A Study on the Impact and Potential of Cryptocurrency
Authors: Srivastava Aviral
Published: October 2021

Introduction: Cryptocurrency is an innovative decentralized virtual currency concept. It has emerged as a new type of investment vehicle in the world, much like gold. The current research was carried out to investigate the impact of cryptocurrency on the world market and its future potential in relation to its rising prominence among investors and traders alike.

Methods: This descriptive-analytical study was based on the interviews of individuals trading in cryptocurrencies and data collected from magazines, websites, electronic newspapers, and research articles. The collected data sets were analyzed by a data analysis model created by me.

Results: Only Cryptocurrencies with decentralized systems are trusted by investors for the fact that they can't be controlled by a single entity. Some countries have legalized crypto while some have banned them. Overall, a majority of the world still has yet to comment on the legality of Bitcoin. The cryptocurrency market is highly volatile as it is based on a simple supply and demand strategy. Bitcoin mining generates 35.95 million tons of carbon dioxide emissions and 12,000 tons of electronic waste a year. The applications of this system promise free, fast transactions, a guarantee of privacy, and a traceable supply-chain framework.

Conclusion: The findings indicated that cryptocurrency has a
swiftly rising user base. With its fair share of advantages and disadvantages, it is a global phenomenon. Given the correlation between investors and asset flow, its future
looks promising. It is necessary to promote this next chapter in the evolution of digital assets.
FREE STATION TASK WITH DRONE
Authors: Zahradník David
Published: October 2021

Using drones with different purposes than only taking photos is nowadays the main direction of drone development. Drones are made for package delivery, people transport, etc. Drone equipped by GNSS RTK and prism can be used as orientation point for the free station. The idea is using drone to get coordinates of total stations inappropriate for GNSS. such as high buildings and forest. The drone can fly above the obstacle causing inappropriate, so the GNSS will compute the position coordinates correctly. Total station will measure distance and angles on prism to get free station coordinates. This article deals with the accuracy of using two points in the free station task. Accuracy of measurement and data is based on real values. Drone can be used as the target if it is not windy, the position accuracy of the target on drone is 5 cm. Wind has no effect on the vertical position accuracy of the the drone. The results show that the same principles and limitations must be observed when measuring the free station task. Horizontal angle between orientation points must be bigger than 100 gon and the zenith angle must be at least 50 gon. The distance between orientation and free station must longer than consequent measured points.

Published: October 2021

The potential to perform spatiotemporal analysis of the Earth's surface, fostered by a large amount of Earth Observation (EO) open data provided by space agencies, brings new perspectives to create innovative applications. Nevertheless, these big datasets pose some challenges regarding storage and analytical processing capabilities. The organization of these datasets as multidimensional data cubes represents the state-of-the-art in analysis-ready data regarding information extraction. EO data cubes can be defined as a set of time-series images associated with spatially aligned pixels along the temporal dimension. Some key technologies have been developed to take advantage of the data cube power. The Open Data Cube (ODC) framework and the Brazil Data Cube (BDC) platform provide capabilities to access and analyze EO data cubes. This paper introduces two new tools to facilitate the creation of land use and land over (LULC) maps using EO data cubes and Machine Learning techniques, and both built on top of ODC and BDC technologies. The first tool is a module that extends the ODC framework capabilities to lower the barriers to use Machine Learning (ML) algorithms with EO data. The second tool relies on integrating the R package named Satellite Image Time Series (sits) with ODC to enable the use of the data managed by the framework. Finally, water mask classification and LULC mapping applications are presented to demonstrate the processing capabilities of the tools.

Authors: Rodrigues Marcos Lima , Körting Thales Sehn , Queiroz Gilberto Ribeiro de
Published: October 2021

Water management is a key field to support life and economic activity nowadays. The greatly increased mechanization of agriculture, mainly through center pivot irrigation systems, represents a big challenge to control this resource. Irrigated agriculture makes up the large majority of consumptive water use, therefore it is important to identify and quantify these systems. Currently, with 6.95x10⁶ ha, Brazil is among the 10 largest countries in irrigation areas in the world. In this study, a combined Computer Vision and Machine Learning approach is proposed for the identification of center pivots in remote sensing images. The methodology is based on Circular Hough Transform (CHT) and Balanced Random Forest (BRF) classifier using vegetation indices NDVI/SAVI generated from Landsat 8 images and Land Use and Land Cover (LULC) data provided by project MapBiomas. The candidate's circles of pivots identified on images are filtered based on vegetation behavior and shape characteristics of these areas. Our approach was able to detect 7358 pivots, reaching 83.86% of Recall for 52 scenes analyzed overall Brazil compared with mapping done by the Brazilian National Water and Sanitation Agency (ANA). In some scenes, the Recall reaches up to 100%.

Authors: Assis Lucas Brandão Monteiro de , Segantine Paulo César Lima
Published: October 2021

Primary Health Care (PHC) is understood as the user's first contact with the Brazilian health system. The planning of PHC units is usually done based on political decisions, which neglect technical aspects related to the theme. The general objective of this study is to present a multicriteria method to assist in planning the implantation of new PHC units, through technical and objective criteria. Then this method is put into practice in the city of São Carlos - SP. The study used as the main tool the Geographic Information System (GIS), and evaluated the quality of six criteria, which are: (1) service area; (2) spatial constraints; (3) risk of natural events; (4) public transportation supply; (5) population distribution; and (6) average income. Each criterion was based on a series of indicators with clear definitions that allowed for the assignment of values according to the theme of the criterion. Each criterion culminated in a thematic map, which, when combined through a raster calculator, allowed the general classification of the study area and the viability of implanting new PHC units. The proposed method proved to be a technical and objective tool, capable of helping in the planning of new PHC units. This is exemplified in the case study in the city of São Carlos- SP.

PENUNDAAN KEWAJIBAN PEMBAYARAN UTANG (PKPU) DALAM MASA PANDEMI COVID-19: ANTARA SOLUSI DAN JEBAKAN
Authors: Budiyono Tri
Published: October 2021

Dunia Bisnis terpapar oleh pandemi Covid-19. Bagi pengusaha yang memiliki kewajiban membayar hutang, dapat dimohonkan pailit yang  pada umumnya akan mengakibatkan terhentinya kegiatan usaha. Untuk menghindari kebangkrutan, debitur dapat mencari formula lain sebagai jalan keluar dari masalah itu. Tujuan penelitian ini adalah untuk mengeksplorasi (kemungkinan) pemanfaatan PKPU dalam masa Covid-19, termasuk kelemahan yang dihadapi oleh pelaku usaha. Penelitian ini adalah penelitian hukum yuridis normatif, dengan pendekatan filosofis dan pendekatan konseptual. Temuan penelitian ini adalah bahwa titik penghubung antara PKPU dan kepailitan menjadi solusi namun mengandung potensi jebakan yang dapat berakibat fatal bagi debitur. Oleh karena itu, debitur harus cermat dalam memilih pola penyelesaian utang yang memiliki risiko paling kecil. Restrukturisasi kredit atau pembiayaan memiliki risiko rendah bagi debitur, sedang PKPU lebih baik diposisikan sebagai pilihan terakhir.
Pieśni masowe Władysława Szpilmana w kontekście dorobku piosenkarskiego kompozytora
Authors: Staśko-Mazur Kamila
Published: October 2021

The aim of the paper is to analyse songs written by Władysław Szpilman during the socialist realism period in the context of the composer’s songwriting achievements. Szpilman’s first hit songs were published as early as the 1930s, and they were followed by others over a period of nearly half a century. The available archival, phonographic and sheet music sources provide information about more than 300 titles which include popular songs, songs for mass performance, for children, for plays and theatrical broadcasts, films and cabarets. The dominant group is that of popular songs and songs for the stage (on themes of love). The group of songs written during the years 1948–56, regarded as mass songs, has distinctive formal features, different musical conceptions, and alongside the march form it includes mostly dance forms (foxtrots, waltzes, polkas, tangos), with the kind of vitality and musical quality that turned them into popular entertainment pieces often achieving the status of hits. In their textual layer the songs are differentiated as well (themes of rebuilding the country, peace, love, work). Evidence of the reception of mass songs shows that they were regarded positively, often as heartening, described as enslaving in view of the context of the performance of selected songs.Popular songs are also characterised by diversity of form and arrangement, differentiated in terms of performance scoring and style (more than 850 archival records). The variety of musical techniques used in this genre, alongside the songs’ melodiousness, ensure that they have a permanent place in the soundscape of the twentieth century.
Budget sharing for multi-analyst differential privacy

Large organizations that collect data about populations (like the US Census Bureau) release summary statistics that are used by multiple stakeholders for resource allocation and policy making problems. These organizations are also legally required to protect the privacy of individuals from whom they collect data. Differential Privacy (DP) provides a solution to release useful summary data while preserving privacy. Most DP mechanisms are designed to answer a single set of queries. In reality, there are often multiple stakeholders that use a given data release and have overlapping but not-identical queries. This introduces a novel joint optimization problem in DP where the privacy budget must be shared among different analysts.

We initiate study into the problem of DP query answering across multiple analysts. To capture the competing goals and priorities of multiple analysts, we formulate three desiderata that any mechanism should satisfy in this setting - The Sharing Incentive, Non-interference, and Adaptivity - while still optimizing for overall error. We demonstrate how existing DP query answering mechanisms in the multi-analyst settings fail to satisfy at least one of the desiderata. We present novel DP algorithms that provably satisfy all our desiderata and empirically show that they incur low error on realistic tasks.
Generating unfavourable VaR scenarios under Solvency II with patchwork copulas
Authors: Pfeifer Dietmar , Ragulina Olena
Published: October 2021

The central idea of the paper is to present a general simple patchwork construction principle for multivariate copulas that create unfavourable VaR (i.e. Value at Risk) scenarios while maintaining given marginal distributions. This is of particular interest for the construction of Internal Models in the insurance industry under Solvency II in the European Union. Besides this, the Delegated Regulation by the European Commission requires all insurance companies under supervision to consider different risk scenarios in their risk management system for the company’s own risk assessment. Since it is unreasonable to assume that the potential worst case scenario will materialize in the company, we think that a modelling of various unfavourable scenarios as described in this paper is likewise appropriate. Our explicit copula approach can be considered as a special case of ordinal sums, which in two dimensions even leads to the technically worst VaR scenario.
Molecular determinants of therapy response of venetoclax-based combinations in acute myeloid leukemia

Published: October 2021

Acute myeloid leukemia (AML) is a heterogeneous, highly malignant disease of the bone marrow. After decades of slow progress, recent years saw a surge of novel agents for its treatment. The most recent advancement is the registration of the Bcl-2 inhibitor ventoclax in combination with a hypomethylating agent (HMA) in the US and Europe for AML patients not eligible for intensive chemotherapy. Treatment of newly diagnosed AML patients with this combination results in remission rates that so far could only be achieved with intensive treatment. However, not all AML patients respond equally well, and some patients relapse early, while other patients experience longer periods of complete remission. A hallmark of AML is its remarkable genetic, molecular and clinical heterogeneity. Here, we review the current knowledge about molecular features of AML that help estimate the probability of response to venetoclax-containing therapies. In contrast to other newly developed AML therapies that target specific recurrent molecular alterations, it seems so far that responses are not specific for a certain subgroup. One exception is spliceosome mutations, where good response has been observed in clinical trials with venetoclax/azacitidine. These mutations are rather associated with a more unfavorable outcome with chemotherapy. In summary, venetoclax in combination with hypomethylating agents represents a significant novel option for AML patients with various molecular aberrations. Mechanisms of primary and secondary resistance seem to overlap with those towards chemotherapy.
An evaluation study of biclusters visualization techniques of gene expression data
Authors: Aouabed Haithem , Elloumi Mourad , Santamaría Rodrigo
Published: October 2021

Biclustering is a non-supervised data mining technique used to analyze gene expression data, it consists to classify subgroups of genes that have similar behavior under subgroups of conditions. The classified genes can have independent behavior under other subgroups of conditions. Discovering such co-expressed genes, called biclusters, can be helpful to find specific biological features such as gene interactions under different circumstances. Compared to clustering, biclustering has two main characteristics: bi-dimensionality which means grouping both genes and conditions simultaneously and overlapping which means allowing genes to be in more than one bicluster at the same time. Biclustering algorithms, which continue to be developed at a constant pace, give as output a large number of overlapping biclusters. Visualizing groups of biclusters is still a non-trivial task due to their overlapping. In this paper, we present the most interesting techniques to visualize groups of biclusters and evaluate them.
Recent advances in bianisotropic boundary conditions: theory, capabilities, realizations, and applications
Authors: Budhu Jordan , Grbic Anthony
Published: October 2021

In recent years, new functionality and unprecedented wavefront control has been enabled by the introduction of bianisotropic metasurfaces. A bianisotropic metasurface is characterized by an electric response, a magnetic response, and an electro-magnetic/magneto-electric response. In general, these metasurfaces consists of an array of metallic or dielectric particles located within a subwavelength thick host medium, and are approximated and modeled as infinitely-thin, idealized sheet boundaries defined along a surface. An appropriate sheet boundary condition which effectively models the tangential field discontinuity due to the array of magnetoelectric inclusions is the Generalized Sheet Transition Condition or GSTC. Several forms of the GSTC appear in literature. Here, we present each interpretation and show how they are related. Synthesis approaches unique to each form are overviewed. By utilizing the GSTC in metasurface design, new possibilities emerge which are not possible with conventional design techniques incorporating only electric or only magnetic responses. Since the metasurfaces are designed using bianisotropic boundary conditions, they must be realized using particles which contain magnetoelectric responses. This review article discusses the design of metasurfaces using the GSTC, and the bianisotropic particles used to realize GSTC’s. Further, it discusses new and recent applications that have emerged due to bianisotropy, and future prospects in metasurface design using bianisotropic boundary conditions. The intent is to provide a comprehensive overview of metasurface design involving bianisotropy and for this review article to serve as a starting point for engineers and scientist that wish to introduce bianisotropy into metasurface design.

Objectives

The aim of the study is to analyze the association of different bitter and sweet gene receptor polymorphisms and bitter and sweet food consumption on formation of dental caries in Turkish adult population.

Methods

This study included 205 adults whose detailed intraoral health examination was completed and decayed, missing, filled teeth (DMFT) index values were recorded. A mini questionnaire was applied to assess the consumption of bitter and sweet food. A venous blood sample from each participant was collected in Ethylenediamine tetraacetic acid (EDTA) tubes. Further, DNA samples were isolated from the blood samples by utilizing a DNA isolation kit, which were stored at +4 °C prior to the analysis. Taste receptor type 2 member 38 (TAS2R38; rs10246939, rs713598, rs1726866), Taste receptor type 1 member 2 (TAS1R2; rs35874116, rs9701796), and Taste receptor type 1 member 3 (TAS1R3; rs307355) gene polymorphisms were detected using real-time polymerase chain reaction (PCR).

Results

There was no statistically significant association between the TAS2R38, TAS1R2, and TAS1R3 gene polymorphism and the DMFT index (p>0.05). No significant difference was found between the consumption of bitter and sweet food and the DMFT index (p>0.05).

Conclusions

TAS2R38 (rs10246939, rs713598, rs1726866), TAS1R2 (rs35874116, rs9701796), and TAS1R3 (rs307355) gene polymorphism may not be associated with the formation of dental caries in the Turkish adult population.
