Published: October 2021

Background and Aim: Salmonella causes most foodborne bacterial illnesses worldwide. It is found in various hosts, including pets, farm animals, and wild animals, as well as the environment. This study aimed to examine the epidemiological relationship between Salmonella isolates from aquatic environments and those from other avian hosts. Materials and Methods: The study examined 12 water samples, 210 aquatic animals, and 45 migratory aquatic bird samples collected from the protected area of Lake Qarun in El-Fayoum Governorate, Egypt, during migration seasons from different waterfowl migration areas (from October 2018 to January 2019). In addition, 45 fecal samples from domestic chickens were collected from the same geographic location from poultry farms. Bacteriological examination and polymerase chain reaction assay of two virulence genes (i.e., invA and stn) were performed to isolate and identify Salmonella. Results: Salmonella was isolated from 58.3% (7/12) of Lake Qarun water samples, 13.3% (6/45) of migratory waterfowl, 6.6% of (3/45) of chickens (Gallus gallus domesticus), and 4.3% (3/70) of fish and pooled brine shrimp. In migratory aquatic bird species that were sampled, Salmonella were isolated from 23.1% (3/13) of Eurasian coot (Fulica atra), 12.5%, (1/8) of green-winged teal (Anas cardolinesis), 10% (2/20) of northern shoveler (Spatula clypeata), and 0% (0/4) of mallard duck (Anas platyrhynchos). In 35 Tilapia, Salmonella was isolated by (8.6%) 5.7% of external surfaces, 2.85% from the intestine, and 0% from the muscle. No Salmonella was isolated from the 175 brine shrimp samples. Phylogenetic analysis using the stn genes of Salmonella isolated from the aquatic environment, migratory aquatic birds, and chicken showed a strong association between these isolates. In addition, a higher nucleotide identity percentage was observed between the sequences recovered from migratory aquatic birds and Lake Qarun water samples. Conclusion: Salmonella distribution was confirmed through migratory aquatic birds, based on our phylogeny tree analysis, Salmonella considered a likely carrier of zoonotic bacterial pathogens. Furthermore, the close relationship between chicken and fish sequences highlights the scenarios of using chicken manure in fish farms and its public health implications. The presence of Salmonella in different environmental sources spotlights the urgent need to control and break down its epidemiological cycle.
Assessment of acclimation of Pinus sibirica mountain ecotypes ex situ on CO2 -gas exchange parameters
Authors: Bender O. G.
Published: October 2021

Carbon dioxide gas exchange of vegetative scion Siberian stone pine ecotypes (Pinus sibirica Du Tour)from the West Sayan mountains altitudinal transect grown on the geographical grafting plantation in the south of theTomsk Region were studied. The altitudinal transect was represented by two ecotypes: low mountain zone and alpine zone.The age of the grafted trees was 20 years. It was shown that the photosynthesis intensity did not differ between ecotypessignificantly, and respiratory activity increased significantly along altitudinal transect and the differences were 40 %between ecotypes. The results of the experiment revealed that the respiration / photosynthesis ratio was 1.5 times higher inalpine ecotype than in low mountain ecotype, which indicates a lower plant productivity of the alpine ecotype. The resultsof measuring stomatal and mesophyll conductance showed that these values differ between ecotypes significantly. Alpineecotype was characterized with more high values of stomatal conductance, but low values of mesophyll conductancerelatively low-mountain ecotype. Alpine ecotype had more high values of CO2 in chloroplasts and electronic transportrates. The obtained data indicate the photosynthetic acclimation when ecotypes were moved to the warmer climate. Therespiratory activity are largely regulated by hereditary factors.

Authors: Ryabova K. K. , Yamskikh I. E. , Stepanov N. V.
Published: October 2021

Corydalis subjenisseensis (Antipova) is a tuberous ephemeroid characterized by a high morphological diversity. During the research work genetic polymorphism of 7 populations Corydalis subjenisseensis s. l., growing in the southof the Yenisei Siberia were analyzed using ISSR markers. The amplification of genomic DNA with 8 ISSR primers yielded100 DNA amplicons of which 78 were polymorphic. The number of amplified DNA fragments, depending on the primer,varied from 9 (ISSR-17) to 21 (HB14). The maximum level of genetic variation was observed for Western Sayan populations growing in aspen and fir forests. The genetic differentiation among populations (Gst) was 0.2415, indicating a highlevel of differentiation. The similarity dendrogram performed in the TFPGA program shows a division into 2 groups: thefirst group includes the Krasnoyarsk and Khakass populations of C. subjenisseensis, the second group includes the Tanzybei populations, which are characterized by a high level of polymorphism. A similar structure is observed when buildingclusters using the Bayesian approach. 69 genotypes are divided into a maximum of 7 genetic clusters. Among the populations of the Tanzybei, individuals of presumably hybridogenic origin are found, grouped around two centers of “attraction”.

Published: October 2021

The Fall armyworm (Spodoptera frugiperda) is considered among the economic important pests in Sudan. Therefore, it became necessary to study and understand its biology and find out the appropriate control measure (s). To achieve the above objective, experiments based on Randomized Complete Block Design (RCBD) were carried out during the period from September 2018 to August 2019, where the Fall armyworm (FAW) was reared in the laboratory and fed on a nutrient médium composed of Corn leaves. The results displayed the ranges of eggs laid by a female was 890–1169. The egg incubation period ranged between 3-13 days. The larval duration ranged between (13-50) days and the pupal duration was between (7-20) days under a temperature of 21-300c and a Relative Humidity (RH) of 65 ± 5%. The longevity of the adults was 1-20 days, and the range of the full lifecycle was (24-100). However, six generations of FAW were obtained within one year. This study concludes that in Sudan FAW breeds continously throughtout the year and it recommends further studies on the biology and effective management of this invasive pest

Published: October 2021

Despite the existing several Sugar manufacturing companies in Sudan, there is an acute shortage in sugar supply, therefore the government imports Sugar to bridge the gap. One of the strategies to be followed is the introduction of Sugar beet (Beta vulgaris) crop, mainly for sugar production. This crop has several advantages over Sugarcane such as short duration, less water requirement, in addition to other uses like animal feed. Therefore it became necessary to have good understanding of agricultural operations, cultural practices and adaptation. However, the main objective of this study was to assess the effect of Nitrogen fertilizer and plant spacing on vegetative growth of Sugar beet. This study was conducted at the farm of the College of Agriculture, University of Bahri, Alkadro, Khartoum State-Sudan; during the season 2016/2017. The experiment was arranged in Split plot in Randomized Complete Block Design with six treatments and four replications. Two plant spacing (15 and 20 cm.) were used as main plot, referred as (S1, S2) along with three levels of Nitrogen fertilizer (40, 80 and 120 kg/ha.), as subplot; referred as (N1, N2 and N3) and the control (0). Data regarding leaf number, leaf area index (LAI), leaf dry weight (g) (LDW), root diameter (mm.) and root fresh weight were recorded and statistically analyzed. The results showed S2 (20 cm) increased all the studied plant characters, namely the leaf number (29.139), leaf area index by (7.54), leaf dry weight (g) to (89.870), root diameter (mm) (94,992), root fresh weight (g) (695.80) compared to S1(1015 cm). On the other hand; the application of N3 (120 kg/ha.) increased the lead number (30.956), leaf Area Index (8.841), Leaf dry weight (102.47), root diameter (97.955) and root fresh weight (851.77) compared to S2 and S1 as presented in (table 4, table 5 and table 6).
Colored Anti-Hail Nets Modify the Ripening Parameters of Nebbiolo and a Smart NIRS can Predict the Polyphenol Features
Authors: Cugnetto Alberto , Masoero Giorgio
Published: October 2021

In the cultivation of vines the risk of hail appears to be increasing with the ongoing climate change. The use of protective plastic nets is spreading, but there is little knowledge on the additional processing costs and on the phenological and qualitative consequences, moreover, as depending on different colors of the nets. Thus, a randomized trial was carried out in Nebbiolo, a wine of great aging, testing three plastic anti-hail nets colored in green, gray and black. Results showed that 24% more-time was necessary for the canopy management practices under the nets. The black nets advanced the ripening process, with a berry weight decrease of about 13%. A significant decrease in the seed number per berry was observed under the black nets (-45%), while a rise (+102%) was observed under the green and gray nets with a parallel increase in the pH of the juice (+13%) and in malic acid (+28%) under the green nets. The berry skin did not show any significant differences in polyphenol and anthocyanin profiles, while the plants that matured in the upper part of the vineyard showed higher level in the berry skin extractable flavan-reactive to vanillin, and total polyphenol. On the other hand, in the seeds grown under green nets an increase in the extractable polyphenol compounds was observed, sign of a delay in seed ripening, with a higher tannin polymerization ratio, preserving the malic acid, and decreasing the acidity of the berry. In conclusion, the use of colored green may be a useful tool against excessive microclimatic warming and / or irradiation. The field internal variability affects much more the ripening dynamics than the nets used. A second aim was to develop a smart NIR SCiOTM model for polyphenols and the results were in line with the favorable expectations, providing R2 predictions of about 0.74 from the skin and 0.81 from the seeds.

This study measures the impact of chloroquine (CQ) therapy in reducing SARS-CoV-2 viral load in infected individuals and hence its transmissibility by describing changes in nasopharyngeal SARS-CoV-2 RNA kinetics in patients receiving standard of care (SOC) or CQ +/- ritonavir-boosted lopinavir (LPV/r). The nasopharyngeal (NP) samples were collected from mild COVID-19 patients admitted at Bamrasnaradura Infectious Diseases Institute between March and April of 2020. These patients either received SOC, or a high dose of CQ with loading dose, or high dose of CQ plus LPV/r. The samples were tested at AFRIMS using a quantitative RT-PCR assay. Levels of CQ in the plasma were measured 6 days post initiation of their treatment. In some instances, viral isolation was attempted to determine SARS-CoV-2 viability. Analyses of the clinical outcomes showed that CQ +/- lopinavir did not contribute significantly to decreasing the number of days with detected SARS-CoV-2 RNA. Viral NP GEs declined faster in the CQ group, but benefits diminished rapidly with delays in treatment initiation.

Published: October 2021

O cadastro é a base do sistema de administração territorial de um país, contém o registro dos distintos interesses sobre o território nacional, descreve geometricamente os imóveis e interopera com outros registros. Normalmente cobre o território continental e se detém ao limite legal marítimo, não obstante, as empresas e os governos precisam de dados e/ou informação referidas aos direitos, restrições e responsabilidades também no ambiente marinho. Na América do Sul a administração destes interesses não foi ainda unificada ou padronizada, muito menos registrada em um sistema de informação geográfica de referência único oficial nacional. Neste contexto, o objetivo deste estudo é contribuir com a modelagem de um Cadastro Marinho (CM) e desenvolver um protótipo de Sistema de Informação Marinha - SIM para sua implementação, previamente à disponibilização de uma infraestrutura de dados espaciais marinha. O SIM foi desenvolvido sob uma estrutura que responde às necessidades de sistematizar informações para o CM ao vincular os dados temáticos a uma saída gráfica para visualizar dados abertos na Argentina, Brasil e Uruguai. Garante a interoperabilidade a partir do estabelecimento de padrões comuns e pode ser o responsável pelo cadastro e pelas atividades de monitoramento do ambiente marinho. Foi construído em JavaScript, com o auxílio de bibliotecas open source como a LeafletJS e suas extensões. Os resultados deste trabalho dão diretrizes para o estabelecimento do marco legal relevante associado a este empreendimento no que se refere ao delineamento da institucionalidade responsável pela estruturação de um CM sob padrões internacionais.
A Cartografia de Síntese como Instrumento para a Avaliação do Potencial da Dinâmica Erosiva Linear em Domínio de Cuesta
Authors: Stefanuto Estêvão Botura , Lupinacci Cenira Maria
Published: October 2021

A erosão do solo pela água é estimada em um custo anual de bilhões de dólares para o PIB global. Para estudar essa problemática, considera-se que avaliar a disposição espacial dos fenômenos erosivos, assim como a interação das variáveis que influenciam sua dinâmica, constitui-se em uma prerrogativa essencial. Neste sentido, o objetivo deste artigo é apresentar procedimentos metodológicos adotados para o desenvolvimento de cartas de síntese a fim de identificar o potencial dos terrenos ao avanço da erosão linear. As variáveis utilizadas para analisar o potencial erosivo foram a morfometria do relevo, as características físicas dos solos e o uso da terra. Foram utilizados princípios da álgebra de mapas, com destaque para a sobreposição ponderada das variáveis, partindo de influências diferentes para cada uma destas e de técnicas distintas para o estabelecimento de pesos para as classes de cada variável. Os documentos cartográficos criados foram avaliados a partir da comparação destes com dados experimentais de campo e de mapeamentos das feições lineares. Constatou-se que as melhores respostas ocorreram quando se considerou influência equânime para as variáveis físicas e de uso da terra, demonstrando que as feições erosivas são fruto da interação entre a ação humana e as características naturais do terreno. Foi possível também concluir que os procedimentos técnicos que permitem obter bons resultados para avaliar o potencial ao desenvolvimento de voçorocas, não respondem adequadamente para sulcos e ravinas, havendo necessidade de adaptações. Considera-se que as cartas elaboradas, assim como os procedimentos metodológicos desenvolvidos, possuem sustentação para a análise da dinâmica erosiva linear em setores de Cuesta, uma vez que foi possível obter produtos cartográficos que apresentaram boa correspondência espacial com as feições erosivas registradas no terreno.
CMAC Trained Optimum Mid course Guidance for Tactical Flight Vehicle
Authors: Kumar G. N. , Sarkar A. K.
Published: October 2021

This paper discusses design and validation of neural network based mid-course guidance law of a surface to air flight vehicle. In present study, initially different optimal trajectories have been generated off-line of different pursuer-evader engagements by ensuring minimum flight time, maximum terminal velocity and favorable handing over conditions for seeker based terminal guidance. These optimal trajectories have been evolved by nonlinear programming based direct method of optimisation. The kinematic information of both pursuer and evader, generated based on these trajectories have been used to train cerebellar model articulate controller (CMAC) neural network. Later for a given engagement scenario an on-line near optimal mid-course guidance law has been evolved based on output of trained network. Training has been carried out by CMAC type supervisory neural network. The tested engagement condition is within input/output training space of neural network. Seeker based homing guidance has been used for terminal phase. Complete methodology has been validated along pitch plane of pursuer-evader engagement. During mid-course phase, the guidance demand has been tracked by attitude hold autopilot and during terminal phase, the guidance demanded lateral acceleration has been tracked by acceleration autopilot. System robustness has been studied in presence of plant parameter variations and sensor noise under Monte Carlo Platform.
Data Acquisition System for Chemical Iodine Generation Suitable for Flowing Medium Chemical Oxygen Iodine Laser
Authors: Dohare Rajeev Kumar , . Mainuddin , Kumar Sanjeev , Singhal Gaurav
Published: October 2021

Development of infrared flowing medium lasers needs to be envisaged in a manner that practical aspects such as system compactness, short readiness time, low system size, weight and power are met to make them field deployable. In this context, the critical aspect of in-situ production of lasing species (Iodine) in Chemical Oxygen Iodine Lasers (COIL), one of the most potent flowing medium lasers, has been investigated. The paper dwells on chemical generation of iodine and its precise flow and parameter control by implementing a customised Data Acquisition System (DAS). Iodine is generated in a chemical reaction of Cuprous Iodide (CuI) with chlorine. This is achieved by precisely controlled flow of chlorine diluted with a carrier gas (N2 ) in a ratio of 1:2. DAS includes regulated gas feed, accurate thermal stabilisation, relevant diagnostics and implementation of necessary safety interlocks in a real time operation scenario for establishing the system efficacy and scalability. The studies have demonstrated chemically generated iodine flow rate of ~ 1.2 mmol.s-1 for Cl2 flow rate of ~3 mmol.s-1 all measured in real time using the developed DAS with a conversion efficiency of 80%. Developed I2 supply system has potential to deliver iodine on demand with required flow rates, measurement uncertainty of ~ 4.5 percent and advantages of smaller specific weight and size with reduced system readiness time and electrical power supply using DAS system with adequate safety interlocks.

Influence of Ink Curing in UV LED Inkjet Printing on Colour Differences, Ink Bleeding and Abrasion Resistance of Prints on Textile
Authors: Lavrič Gregor , Karlovits Igor , Muck Deja , Forte Tavčer Eva Petra , Kavčič Urška
Published: October 2021

Digital printing techniques are increasingly present in the field of textile printing. Particularly prominent is the inkjet printing technique using water-based inks, UV LED inkjet printing also increasingly being in use. UV LED inkjet is primarily not intended for direct clothing printing; however, it can be used especially as a hybrid solution in the soft signage market. It is a great option for the printers that are not engaged only in textile printing, and want a more versatile print portfolio, extending it to non-clothing textile products, e.g. soft signage and non-wearable products. As these types of products often require colour reproduction of logos, accurate colour reproduction, good ink adhesion and sharpness are important just like in other printing technologies. In order to evaluate the impact of UV LED radiation amount on colour differences, ink bleeding and abrasion resistance, six different fabric samples (five woven and one nonwoven) were printed using a UV LED inkjet printer. Based on the results of colour difference, it was established that a reduction of UV radiation (by half the manufacturer’s recommended amount) had no effect on this parameter. However, perceptible colour differences were observed with the use of different M measurement conditions defined by the international standard ISO 13655-2017. Reducing the amount of UV radiation had no effect on the adhesion and durability of the printed ink. Small differences detected in these two parameters were mainly a consequence of the properties of textile materials and not of decreased UV radiation.

Naturalistyczna muzykologia systematyczna wobec poglądów Meyera na emocje i znaczenie w muzyce
Authors: Podlipniak Piotr
Published: October 2021

Leonard B. Meyer’s book Emotion and Meaning in Music was published more than half a century ago. It still provides inspiration for musicologists with various specialisms to undertake research aimed at understanding the intriguing link between music and emotions and the relationship between musical structure and meaning. Since the publication of this outstanding volume we have seen extraordinarily dynamic development of the musicological disciplines constituting that part of systematic musicology which is based on the premises of naturalism. The article focuses on those selected research areas of thisbranch of musicology where the influence of the ideas first presented in the above volume is particularly significant. The most important of Meyer’s postulates in naturalistically oriented systematic musicology that continue to be discussed include: the key role of expectation in shaping our emotional reactions to the musical passages we hear and the inner musical character of the affective meanings created in this way. The main challenges faced by Meyer’s postulates during the recent decades are examined, and the solutions to them proposed within the framework of naturalistically oriented thinking about music.
Cryptanalysis of an encrypted database in SIGMOD '14
Authors: Cao Xinle , Liu Jian , Lu Hao , Ren Kui
Published: October 2021

Encrypted database is an innovative technology proposed to solve the data confidentiality issue in cloud-based DB systems. It allows a data owner to encrypt its database before uploading it to the service provider; and it allows the service provider to execute SQL queries over the encrypted data. Most of existing encrypted databases (e.g., CryptDB in SOSP '11) do not support data interoperability: unable to process complex queries that require piping the output of one operation to another.

To the best of our knowledge, SDB (SIGMOD '14) is the only encrypted database that achieves data interoperability. Unfortunately, we found SDB is not secure! In this paper, we revisit the security of SDB and propose a ciphertext-only attack named
co-prime attack.
It successfully attacks the common operations supported by SDB, including
addition, comparison, sum, equi-join
and
group-by.
We evaluate our attack in three real-world benchmarks. For columns that support
addition
and
comparison
, we recover 84.9% -- 99.9% plaintexts. For columns that support
sum, equi-join
and
group-by
, we recover 100% plaintexts.

Besides, we provide potential countermeasures that can prevent the attacks against
sum, equi-join, group-by
and
addition.
It is still an open problem to prevent the attack against
comparison.
Distributed deep learning on data systems

Published: October 2021

Deep learning (DL) is growing in popularity for many data analytics applications, including among enterprises. Large business-critical datasets in such settings typically reside in RDBMSs or other data systems. The DB community has long aimed to bring machine learning (ML) to DBMS-resident data. Given past lessons from in-DBMS ML and recent advances in scalable DL systems, DBMS and cloud vendors are increasingly interested in adding more DL support for DB-resident data. Recently, a new parallel DL model selection execution approach called Model Hopper Parallelism (MOP) was proposed. In this paper, we characterize the particular suitability of MOP for DL on data systems, but to bring MOP-based DL to DB-resident data, we show that there is no single "best" approach, and an interesting tradeoff space of approaches exists. We explain four canonical approaches and build prototypes upon Greenplum Database, compare them analytically on multiple criteria (e.g., runtime efficiency and ease of governance) and compare them empirically with large-scale DL workloads. Our experiments and analyses show that it is non-trivial to meet all practical desiderata well and there is a Pareto frontier; for instance, some approaches are 3x-6x faster but fare worse on governance and portability. Our results and insights can help DBMS and cloud vendors design better DL support for DB users. All of our source code, data, and other artifacts are available at https://github.com/makemebitter/cerebro-ds.

Published: October 2021

Deep Learning (DL) has created a growing demand for simpler ways to develop complex models and efficient ways to execute them. Thus, a significant effort has gone into frameworks like PyTorch or TensorFlow to support a variety of DL models and run efficiently and seamlessly over heterogeneous and distributed hardware. Since these frameworks will continue improving given the predominance of DL workloads, it is natural to ask what else can be done with them. This is not a trivial question since these frameworks are based on the efficient implementation of tensors, which are well adapted to DL but, in principle, to nothing else. In this paper we explore to what extent Tensor Computation Runtimes (TCRs) can support non-ML data processing applications, so that other use cases can take advantage of the investments made on TCRs. In particular, we are interested in graph processing and relational operators, two use cases very different from ML, in high demand, and complement quite well what TCRs can do today. Building on HUMMINGBIRD, a recent platform converting traditional machine learning algorithms to tensor computations, we explore how to map selected graph processing and relational operator algorithms into tensor computations. Our vision is supported by the results: our code often outperforms custom-built C++ and CUDA kernels, while massively reducing the development effort, taking advantage of the cross-platform compilation capabilities of TCRs.
Preference queries over taxonomic domains

Published: October 2021

When composing multiple preferences characterizing the most suitable results for a user, several issues may arise. Indeed, preferences can be partially contradictory, suffer from a mismatch with the level of detail of the actual data, and even lack natural properties such as transitivity. In this paper we formally investigate the problem of retrieving the best results complying with multiple preferences expressed in a logic-based language. Data are stored in relational tables with taxonomic domains, which allow the specification of preferences also over values that are more generic than those in the database. In this framework, we introduce two operators that rewrite preferences for enforcing the important properties of transitivity, which guarantees soundness of the result, and specificity, which solves all conflicts among preferences. Although, as we show, these two properties cannot be fully achieved together, we use our operators to identify the only two alternatives that ensure transitivity and minimize the residual conflicts. Building on this finding, we devise a technique, based on an original heuristics, for selecting the best results according to the two possible alternatives. We finally show, with a number of experiments over both synthetic and real-world datasets, the effectiveness and practical feasibility of the overall approach.

The BCR-ABL oncogene is a tyrosine kinase gene that is over-expressed in CML. It inhibits the TGF-β1 signaling pathway. Due to resistance of cells to the tyrosine kinase inhibitor, STI-571, the combined effect of STI-571 and TGF-β1 on K562 cells was studied in the present research. Results revealed that the TGF-β1 cell signaling pathway, which is activated in K562 cells treated with TGF-β1, activates collective cell signaling pathways involved in survival and apoptosis.

It is noteworthy that treating K562 cells with STI-571 triggered apoptotic pathways, accompanied by a reduction in proteins such as Bcl-xL, Bcl-2, p-AKT, p-Stat5, p-FOXO3, and Mcl-1 and an increase in the pro-apoptotic proteins PARP cleavage, and p27, leading to an increase in sub-G1 phase-arrested and Annexin-positive cells.

Interestingly, the proliferation behavior of TGF-β1-induced cells was changed with the combination therapy, and STI-571-induced apoptosis was also prompted by this combination. Thus, combination treatment appears to promote sub-G1 cell cycle arrest compared to individually treated cells. Furthermore, it strongly triggered apoptotic signaling. In conclusion, TGF-β1 did not negatively impact the effect of STI-571, based on positive annexin cells, and AKT protein phosphorylation remains effective in apoptosis.

Published: October 2021

Radio Frequency (RF) plays a vital role nowadays in harvesting RF Energy from the ambient source. An antenna is required to harvest RF energy and solve the spectrum underutilization problem for the Cognitive Radio (CR) system. This paper presents an optimization of a reconfigurable Coplanar Waveguide Antenna (CPW), which harvests RF energy and is also used for sensing and communication purposes. The performance metrics of the proposed antenna are gain, radiation efficiency, front-back ratio (FBR) and group delay. First, the optimized CPW antenna (sensing antenna) is designed and fabricated in the FR4 substrate for the wideband frequency range of (0.25–3 GHz) with the fractional bandwidth percentage of 175%. The gain of the proposed optimized CPW antenna for different frequency band is: DTV band (UHF-0.47 GHz)-3.327 dBi, GSM 900-2.39 dBi, GSM 1800-3.42 dBi, 3G-3.227 dBi, and Wi-Fi-3.21 dBi. The average gain of the optimized CPW antenna for the frequency range of (0.25–3 GHz) is 3.11 dBi, and the maximum radiation efficiency of the antenna is 91.05%. Next, the optimized CPW antenna is reconfigurable, and it can be reconfigured for a specific frequency band using a PIN diode switch. When the PIN diode switch is in ON state, the antenna acts as a reconfigurable antenna (communicating antenna), and it is operated for the specific frequency band of (0.47 GHz-DTV [UHF] band), (0.9, 1.8, and 2.1 GHz-mobile bands), and (2.4 GHz-Wi-Fi bands). The maximum gain of the optimized frequency reconfigurable CPW antenna is 3.61 dBi, and the radiation efficiency is 92.5%. In the OFF state, the antenna acts as a sensing antenna, and it operates at a wideband frequency range of (0.25–3 GHz). Finally, the prototype of a four-stage Villard voltage multiplier RF-dc conversion circuit using an adjustable impedance matching network is proposed for powering the cognitive radio applications.
Functional characterisation of two receptor interaction determinants in human thymic stromal lymphopoietin

Published: October 2021

Thymic stromal lymphopoietin (TSLP) is a pro-inflammatory cytokine with important pathological roles in Asthma bronchiale, malignant tumours and other diseases. The heterodimeric human TSLP receptor (hTSLPR) consists of the TSLP-binding subunit (TSLPRα) and the IL-7Rα-subunit. We studied the properties of hTSLP variants with mutations in their bipartite interaction interface towards IL-7Rα. One mutant (T46D/K101D) showed only mild impairment in receptor affinity but a massive reduction in biological activity. To facilitate the future development of hTSLP mutants with drug properties, we have devised a eukaryontic cytokine display assay with activity read-out and intrinsic genotype-phenotype coupling.
The Imaginative Impulse: Philosophies of Film and Chinese Aesthetic Sensibilities
Authors: Chen Shan
Published: October 2021

This article investigates the similarities between inherent Chinese aesthetic sensibilities and modern cinematic thought and introduces Chinese films’ exploration of oriental film aesthetics during the “seventeen-year period” (1949–1966). It serves to remind us that in seeking to understand the developmental trajectory and driving forces behind Chinese film art, it is important to examine the changes in and contexts of modern Chinese modes of thought—especially artistic thought—so as to reveal the aesthetic sensibilities of modern Chinese films; the true nature of their artistic inheritance; and their foundation and potential for modern transformations. The article makes an original Chinese contribution to the creation of a new film aesthetics for future images in the era of artificial intelligence.

Published: October 2021

Objectives

The present study aimed to survey the prevalence of gestational diabetes mellitus (GDM) in Southern China and further to analyze the correlation between the prevalence of GDM and maternal age.

Methods

A retrospective cross-sectional study was carried out at the Southern Medical University Affiliated Maternal & Child Health Hospital of Foshan, Foshan, China between January and April 2020. Oral glucose tolerance tests (OGTT) was performed, using a 75 g glucose load and venous samples were drawn at 0 h, 1 h and 2 h at 24–28 weeks of gestation. GDM was diagnosed by International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria.

Results

The prevalence of GDM was 14.87% by IADPSG criteria. The incidence of GDM outcome increased and plasma glucose levels remained high among the age subgroups (<20, 20–24, 25–29, 30–34, 35–39, ≥40 years old) in pregnant women. Moreover, the levels of plasma glucose levels after OGTT kept rising among the pregnant women with non-gestational diabetes mellitus (non-GDM). Furthermore, pregnant women were inclined to have abnormal plasma glucose values at 1 h and 2 h than initial fasting plasma glucose (FPG) after OGTT as the age increased.

Conclusions

Our findings demonstrate that the incidence of GDM outcome and plasma glucose levels increase as the maternal age increase.

A global random walk on grid algorithm for second order elliptic equations
Authors: Sabelfeld Karl K. , Smirnov Dmitry , Dimov Ivan , Todorov Venelin
Published: October 2021

In this paper we develop stochastic simulation methods for solving large systems of linear equations, and focus on two issues: (1) construction of global random walk algorithms (GRW), in particular, for solving systems of elliptic equations on a grid, and (2) development of local stochastic algorithms based on transforms to balanced transition matrix. The GRW method calculates the solution in any desired family of prescribed points of the gird in contrast to the classical stochastic differential equation based Feynman–Kac formula. The use in local random walk methods of balanced transition matrices considerably decreases the variance of the random estimators and hence decreases the computational cost in comparison with the conventional random walk on grids algorithms.
A wavelength and polarization selective photon sieve for holographic applications

Published: October 2021

Optical metasurfaces are perfect candidates for the phase and amplitude modulation of light, featuring an excellent basis for holographic applications. In this work, we present a dual amplitude holographic scheme based on the photon sieve principle, which is then combined with a phase hologram by utilizing the Pancharatnam–Berry phase. We demonstrate that two types of apertures, rectangular and square shapes in a gold film filled with silicon nanoantennas are sufficient to create two amplitude holograms at two different wavelengths in the visible, multiplexed with an additional phase-only hologram. The nanoantennas are tailored to adjust the spectral transmittance of the apertures, enabling the wavelength sensitivity. The phase-only hologram is implemented by utilizing the anisotropic rectangular structure. Interestingly, such three holograms have quantitative mathematical correlations with each other. Thus, the flexibility of polarization and wavelength channels can be utilized with custom-tailored features to achieve such amplitude and phase holography simultaneously without sacrificing any space-bandwidth product. The present scheme has the potential to store different pieces of information which can be displayed separately by switching the wavelength or the polarization state of the reading light beam.
An Evaluation of the US Relations with Sub-Saharan Africa in The 21st Century
Authors: Simuziya Nsama Jonathan
Published: October 2021

This study assesses the viability of relations between the US and sub-Saharan Africa by examining the trends of their political and economic cooperation. Given the high number of member states involved in this partnership, a strong alliance could influence good governance practices beyond their continents. The gist of their relationship challenges lies in claims by sub-Saharan states that the partnership is one-sided in favour of the US, turning the enterprise into a zero-sum game. For instance, the US insist on their partners to meet thresholds of ‘good governance practices’ as determined by the US itself. However, governance breaches are revealed from both sides. Data for this study were gathered from secondary and primary sources. The study concludes that the relationship is lukewarm due to mistrust, and this has led to the unsuccessful US involvement in sub-Saharan Africa.
