RNA-Seq analysis of a Pax3-expressing myoblast clone in-vitro and effect of culture surface stiffness on differentiation
Authors: Richardson Louise , Wang Dapeng , Hughes Ruth , Johnson Colin A. , Peckham Michelle
Published: February 2022

Skeletal muscle satellite cells cultured on soft surfaces (12 kPa) show improved differentiation than cells cultured on stiff surfaces (approximately 100 kPa). To better understand the reasons for this, we performed an RNA-Seq analysis for a single satellite cell clone (C1F) derived from the H2kb-tsA58 immortomouse, which differentiates into myotubes under tightly regulated conditions (withdrawal of ɣ-interferon, 37 °C). The largest change in overall gene expression occurred at day 1, as cells switched from proliferation to differentiation. Surprisingly, further analysis showed that proliferating C1F cells express Pax3 and not Pax7, confirmed by immunostaining, yet their subsequent differentiation into myotubes is normal, and enhanced on softer surfaces, as evidenced by significantly higher expression levels of myogenic regulatory factors, sarcomeric genes, enhanced fusion and improved myofibrillogenesis. Levels of mRNA encoding extracellular matrix structural constituents and related genes were consistently upregulated on hard surfaces, suggesting that a consequence of differentiating satellite cells on hard surfaces is that they attempt to manipulate their niche prior to differentiating. This comprehensive RNA-Seq dataset will be a useful resource for understanding Pax3 expressing cells.

Published: February 2022

The high quality, yield and purity total RNA samples are essential for molecular experiments. However, harvesting high quality RNA in Lilium davidii var. unicolor is a great challenge due to its polysaccharides, polyphenols and other secondary metabolites. In this study, different RNA extraction methods, namely TRIzol method, the modified TRIzol method, Kit method and cetyltrimethylammonium bromide (CTAB) method were employed to obtain total RNA from different tissues in L. davidii var. unicolor. A Nano drop spectrophotometer and 1% agarose gel electrophoresis were used to detect the RNA quality and integrity. Compared with TRIzol, Kit and CTAB methods, the modified TRIzol method obtained higher RNA concentrations from different tissues and the A260/A280 ratios of RNA samples were ranged from 1.97 to 2.27. Thus, the modified TRIzol method was shown to be the most effective RNA extraction protocol in acquiring RNA with high concentrations. Furthermore, the RNA samples isolated by the modified TRIzol and Kit methods were intact, whereas different degrees of degradation happened within RNA samples isolated by the TRIzol and CTAB methods. In addition, the modified TRIzol method could also isolate high-quality RNA from other edible lily bulbs. Taken together, the modified TRIzol method is an efficient method for total RNA isolation from L. davidii var. unicolor.

Published: February 2022

Subcutaneous fat and intramuscular fat (IMF) deposition are closely related to meat production and pork quality. Dingyuan pig, as a native pig breed in China, low selection leads to obvious genetic and phenotypic differences in the population. Individuals with extreme fat content in the population are ideal models for studying the mechanism of fat deposition. In this study, we used RNA-Seq and tandem mass tags-based (TMT) proteomics to analyze the key pathways and genes that specifically regulate subcutaneous fat and IMF deposition in Dingyuan pigs. We identified 191 differentially expressed genes (DEGs) and 61 differentially abundant proteins (DAPs) in the high and low back fat thickness (HBF, LBF) groups, 85 DEGs and 12 DAPs were obtained in the high and low intramuscular fat (HIMF, LIMF) groups. The functional analysis showed that the DEGs and DAPs in the backfat groups were mainly involved in carbohydrates, amino acids, and fatty acids metabolism, whereas the IMF groups were involved in the insulin pathway, longevity, and some disease-related pathways. We found 40 candidate genes that might tissue-specifically lipids deposition for subcutaneous and intramuscular fat. Our research provides theoretical reference materials for the improvement of fat deposition traits of local pig breeds in my country.
Investigating weighted fishing hooks for seabird bycatch mitigation
Authors: Gilman Eric , Musyl Michael , Wild Michael , Rong Hua , Chaloupka Milani
Published: February 2022

Fisheries bycatch threatens the viability of some seabird populations and reduces fishing efficiency. Albatross bycatch in a US North Pacific tuna longline fishery has increased over the past decade and now exceeds 1000 annual captures. Seabirds interacting with this fishery reach hooks at depths up to 1 m. A branchline weight’s mass and distance from the hook affect seabird catch rates. We conducted experimental fishing to compare the commercial viability of a weighted hook relative to conventional gear with weights attached 0.75 m from the hook. We used a Bayesian random effects meta-analytic regression modelling approach to estimate pooled expected species-specific log relative risk of capture on conventional versus experimental gear. There was a significant 53% (95% HDI: − 75 to − 25%) decrease in retained species’ catch rates on experimental hooks, indicating an unacceptable economic cost, and no significant effect for discarded species. Using a Bayesian general linear mixed regression modelling approach, experimental hooks sank to 85 cm ca. 1.4 times (95% HDI: 1.37–1.48) faster than control hooks. Given their potential to reduce seabird catch rates, eliminate safety risks from bite-offs and facilitate robust compliance monitoring, it is a priority to find a weighted hook design with acceptable catch rates.
Comprehensive analysis of the expression and significance of CXCLs in human diffuse large B-cell lymphoma
Authors: Zhou Xiaonan , Guo Shizhu , Shi Yonghong
Published: February 2022

CXCL chemokines (CXCLs) are small cytokines or signal proteins secreted by cells that have been proven to be linked to the occurrence and development of many kinds of cancer. However, the expression and diagnostic and prognostic value of CXCLs in diffuse large B-cell lymphoma (DLBCL) remain to be further studied. We obtained CXCL transcription and survival data of patients with DLBCL from Oncomine, Gene Expression Profiling Interactive Analysis (GEPIA), The Cancer Genome Atlas (TCGA), TIMER and cBioPortal databases. R software, STRING and EXCEL were used to process the data. This study discovered that the expression levels of CXCL9-14 in DLBCL were higher than those in normal tissues, while CXCL4, CXCL7 and CXCL8 were lower in tumor than in normal tissues. The expression levels of CXCL2, CXCL10 and CXCL11 were related to tumor stage. CXCL9-14 could be used as an auxiliary molecular marker for the diagnosis of DLBCL. CXCL17 might be a potential prognostic marker of DLBCL.
Ether anesthetics prevents touch-induced trigger hair calcium-electrical signals excite the Venus flytrap

Published: February 2022

Plants do not have neurons but operate transmembrane ion channels and can get electrical excited by physical and chemical clues. Among them the Venus flytrap is characterized by its peculiar hapto-electric signaling. When insects collide with trigger hairs emerging the trap inner surface, the mechanical stimulus within the mechanosensory organ is translated into a calcium signal and an action potential (AP). Here we asked how the Ca2+ wave and AP is initiated in the trigger hair and how it is feed into systemic trap calcium-electrical networks. When Dionaea muscipula trigger hairs matures and develop hapto-electric excitability the mechanosensitive anion channel DmMSL10/FLYC1 and voltage dependent SKOR type Shaker K+ channel are expressed in the sheering stress sensitive podium. The podium of the trigger hair is interface to the flytrap’s prey capture and processing networks. In the excitable state touch stimulation of the trigger hair evokes a rise in the podium Ca2+ first and before the calcium signal together with an action potential travel all over the trap surface. In search for podium ion channels and pumps mediating touch induced Ca2+ transients, we, in mature trigger hairs firing fast Ca2+ signals and APs, found OSCA1.7 and GLR3.6 type Ca2+ channels and ACA2/10 Ca2+ pumps specifically expressed in the podium. Like trigger hair stimulation, glutamate application to the trap directly evoked a propagating Ca2+ and electrical event. Given that anesthetics affect K+ channels and glutamate receptors in the animal system we exposed flytraps to an ether atmosphere. As result propagation of touch and glutamate induced Ca2+ and AP long-distance signaling got suppressed, while the trap completely recovered excitability when ether was replaced by fresh air. In line with ether targeting a calcium channel addressing a Ca2+ activated anion channel the AP amplitude declined before the electrical signal ceased completely. Ether in the mechanosensory organ did neither prevent the touch induction of a calcium signal nor this post stimulus decay. This finding indicates that ether prevents the touch activated, glr3.6 expressing base of the trigger hair to excite the capture organ.

Bleaching physiology: who's the ‘weakest link’ — host vs. symbiont?
Authors: Roberty Stéphane , Plumier Jean-Christophe
Published: February 2022

Environmental stress, such as an increase in the sea surface temperature, triggers coral bleaching, a profound dysfunction of the mutualist symbiosis between the host cnidarians and their photosynthetic dinoflagellates of the Family Symbiodiniaceae. Because of climate change, mass coral bleaching events will increase in frequency and severity in the future, threatening the persistence of this iconic marine ecosystem at global scale. Strategies adapted to coral reefs preservation and restoration may stem from the identification of the succession of events and of the different molecular and cellular contributors to the bleaching phenomenon. To date, studies aiming to decipher the cellular cascade leading to temperature-related bleaching, emphasized the involvement of reactive species originating from compromised bioenergetic pathways (e.g. cellular respiration and photosynthesis). These molecules are responsible for damage to various cellular components causing the dysregulation of cellular homeostasis and the breakdown of symbiosis. In this review, we synthesize the current knowledge available in the literature on the cellular mechanisms caused by thermal stress, which can initiate or participate in the cell cascade leading to the loss of symbionts, with a particular emphasis on the role of each partner in the initiating processes.

Aims. We present the results of the analysis of five observations of the globular clutser 47 Tucanae (47 Tuc) with the extended Roentgen Survey with an Imaging Telescope Array (eROSITA) on board the Spektrum-Roentgen-Gamma (Spektr-RG, SRG). We study the X-ray population in the field of one of the most massive globular clusters in our Milky Way. We focused on the classification of point-like sources in the field of 47 Tuc. The unresolved dense core of 47 Tuc (1.7 radius) and also sources that show extended emission are excluded from this study.

Methods. We applied different methods of X-ray spectral and timing analysis together with multi-wavelength studies to classify the X-rays sources in the field of 47 Tuc.

Results. We detected 888 point-like sources in the energy range of 0.2–5.0 keV. We identified 126 background active galactic nuclei and 25 foreground stars. One of the foreground stars is classified as a variable M dwarf. We also classified 14 X-ray sources as members of 47 Tuc, including one symbiotic star, two quiescent low-mass X-ray binaries, and four cataclysmic variables. There are also five X-ray sources that can either be a cataclysmic variable or a contact binary, and also one X-ray source can be an active binary (type RS CVn). We identified one X-ray binary that belongs to the Small Magellanic Cloud. Moreover, we calculated the X-ray luminosity function of 47 Tuc. No significant population that seems to belong to the globular cluster is observed in the energy range of 0.5–2.0 keV using eROSITA observations.
Recycling of the first atmospheres of embedded planets: Dependence on core mass and optical depth
Authors: Moldenhauer T. W. , Kuiper R. , Kley W. , Ormel C. W.
Published: February 2022

Context. Recent observations found close-in planets with significant atmospheres of hydrogen and helium in great abundance. These are the so-called super-Earths and mini-Neptunes. Their atmospheric composition suggests that they formed early during the gas-rich phase of the circumstellar disk and were able to avoid becoming hot Jupiters. As a possible explanation, recent studies explored the recycling hypothesis and showed that atmosphere-disk recycling is able to fully compensate for radiative cooling and thereby halt Kelvin-Helmholtz contraction to prevent runaway gas accretion.

Aims. To understand the parameters that determine the efficiency of atmospheric recycling, we extend our earlier studies by exploring the effects of the core mass, the effect of circumstellar gas on sub-Keplerian orbits (headwind), and the optical depth of the surrounding gas on the recycling timescale. Additionally, we analyze their effects on the size and mass of the forming atmosphere.

Methods. We used three-dimensional (3D) radiation-hydrodynamic simulations to model a local shearing box centered on the planet. Our planet is located at a separation of ap = 0.1 au from its solar-type host star, and we scanned the core mass range from 1 to 10 MEarth. In order to measure and track the recycling of the atmosphere, we employed tracer particles as well as tracer fluids after thermodynamic equilibrium was reached.

Results. For the explored parameter space, all simulations eventually reach an equilibrium where heating due to hydrodynamic recycling fully compensates radiative cooling. In this equilibrium, the atmosphere-to-core mass ratio stays well below 10%, preventing the atmosphere from becoming self-gravitating and entering runaway gas accretion. Higher core masses cause the atmosphere to become turbulent, which further enhances recycling. Compared to the core mass, the effect of the headwind on the recycling timescale is negligible. The opacity has no significant effect on the recycling timescale, which demonstrates that the Kelvin-Helmholtz contraction timescale and the atmosphere-disk recycling timescale are independent of each other.

Conclusions. Even for our highest core mass of 10 MEarth, atmosphere-disk recycling is efficient enough to fully compensate for radiative cooling and prevent the atmosphere from becoming self-gravitating. Hence, in-situ formation of hot Jupiters is very unlikely, and migration of gas giants is a key process required to explain their existence. Our findings imply that atmosphere-disk recycling is the most natural explanation for the prevalence of close-in super-Earths and mini-Neptunes.
Mislabelling may explain why some prohibited invasive aquatic plants are still being sold in Belgium
Authors: Van den Neucker Tom , Scheers Kevin
Published: February 2022

In Belgium, a voluntary code of conduct intended to prevent introduction of invasive plants through the horticultural trade has been implemented since 2009. European Regulation 1143/2014 that imposes legal bans on a number of plant taxa entered into force in 2015. However, studies regarding the presence of invasive plants in the Belgian horticultural trade remained scarce. In 2016–2017 and in 2020, we surveyed a total of 11 garden centres specialized in water gardening and compiled a list of 285 aquatic plant taxa that were being traded. In 2020, four Belgian Consensus List species and one Communication List species were still offered for sale. Also, three species of Union Concern were still being sold in 2020. The plants of the Belgian Lists that were still being sold in 2020 and all except one of the European Union List plants were mislabelled, either because of misidentification or because a taxonomic synonym was used. Mislabelling may explain why some prohibited plants were still in trade. Therefore, retailers and plant producers should be encouraged to correctly identify the plants that are being traded. Our study illustrates that regular surveys are essential to assess the effectiveness of voluntary codes of conduct and legal trade bans.

La perception est la compréhension des informations que les organes sensoriels envoient au cerveau. Visuelles, elles sont transmises au cortex visuel dans le lobe occipital. L’imagerie par résonance magnétique montre que cette information est traitée dans le cortex temporal. Deux exemples seront discutés dans cette revue : la reconnaissance des mots écrits, et celle des visages. Dans le premier cas, une hypothèse, la hiérarchie de la combinaison de détecteurs locaux, explique les propriétés d’invariance de la forme des lettres. Dans le second, le code utilisé dans le cerveau du singe macaque pour reconnaître les visages a été déchiffré : à partir de l’activité électrique de 200 neurones du cortex temporal inférieur, il est en effet possible à un singe de connaître le visage qui lui a été présenté.
L’autophagie modulée par les virus
Authors: Leonardi Lucas , Sibéril Sophie , Alifano Marco , Cremer Isabelle , Joubert Pierre-Emmanuel
Published: February 2022

L’autophagie est un processus métabolique important pour maintenir l’homéostasie cellulaire à des moments critiques du développement et/ou en réponse à un stress environnemental. Cela est particulièrement pertinent dans le cas des cancers, pour lesquels il a été montré que l’autophagie a un impact important sur leur survenue et sur la croissance tumorale. D’une part, elle limite la transformation cancéreuse des cellules précancéreuses à un stade précoce, mais, d’autre part, elle favorise la survie et la prolifération cellulaires, les métastases et la résistance aux thérapies anti-tumorales dans les tumeurs plus avancées. L’autophagie peut être induite par une grande variété de stimulus extracellulaires et intracellulaires. Les infections virales ont souvent été associées à une modulation de l’autophagie, dont l’impact sur la réplication virale ou la survie des cellules infectées diffère selon le modèle étudié. Dans un contexte tumoral, certains mécanismes moléculaires complexes par lesquels la modulation de l’autophagie par les virus peut influencer le développement des cellules précancéreuses ou cancéreuses ont été révélés. Cette revue présente les découvertes récentes concernant les répercussions d’une perturbation de l’autophagie par l’infection virale sur la survenue et la progression des tumeurs cancéreuses.

Published: February 2022

A polarised radiative transfer model (POMEROL) has been developed to compute the polarisation measured by a virtual instrument in a given nocturnal environment. This single-scattering model recreates real-world conditions (among them atmospheric and aerosol profiles, light sources with complex geometries at the ground and in the sky, terrain obstructions). It has been successfully tested at mid-latitudes where sky emissions are of weak intensity. We show a series of comparisons between POMEROL predictions and polarisation measurements during two field campaigns in the auroral zone, in both quiet and active conditions. These comparisons show the strength of the model to assess the aerosol characteristics in the lower atmosphere by using a mesospheric line. They also show that three main upper atmosphere emissions must be polarised: the green atomic oxygen line at 557.7 nm and the 1stN2+negative band at 391.4 nm (purple) and 427.8 nm (blue). This polarisation can be either created directly at the radiative de-excitation or may occur when the non-polarised emission crosses the ionospheric currents. We provide some of the potentialities it offers in the frame of space weather. These require refinements of the preliminary modeling approach considered in the present study.

Clinical Aspects of Dialysis Interventions: Physical and Sonographic Findings
Authors: Niyyar Vandana Dua , Agarwal Anil K. , Salman Loay H.
Published: February 2022

Physical examination (PE) of arteriovenous access remains of high clinical value and continues to be recommended by leading societies and guidelines. PE is easy to learn and perform. Once learned, examiners can provide a comprehensive arteriovenous (AV) access examination in 20 to 30 seconds. Therefore, we continue to advocate that AV access PE should be part of the training for all dialysis care providers. Similarly, ultrasound can provide important AV access evaluation and provide key information. It is relatively cheap and can be readily available at the bed side. Additionally, it is well accepted by patients, as it is not expected to be associated with pain or discomfort during the examination. We present in this review the key components of PE, signs and symptoms of AV access dysfunction, and the role of ultrasound in AV access evaluation as a complementary tool to PE.

Published: February 2022

This paper reports an inkjet-printed radiation pattern reconfigurable (RPR) receiving antenna for wireless power transfer application with 2.45 GHz frequency. Conductive ink EGaIn and polyimide are employed as the radiator and the flexible substrate, respectively. The geometrical parameters of the proposed antenna are optimized to obtain a favorable matching of impedance, and the S11 at 2.45 GHz is −22.71 dB, with good agreement between the simulation and measurement results. The reconfigurable characteristics of the pattern are achieved by the flexible antenna bent conformally, while the trends of S11 are investigated under various bending radii of curvature. The performance of the RPR flexible antenna receiving RF energy under multi-angle incidences is verified experimentally.
Research on anti-irradiation properties of PDMS/MWCNT composite force-sensitive structure

Published: February 2022

This study aimed to design a polydimethylsiloxane multi-walled carbon nanotube composite force-sensitive structure. Five composite materials with different volume fractions of carbon nanotubes were prepared, and the microscopic morphology of the samples recorded. Conductive pathways were formed inside the composite materials. The force-sensitive performance was verified through tensile experiments on the material. The sample with a content of 3 vol. % had a sensitivity of up to 165, which was good for detecting small strains. The samples were irradiated with 60Co-γ rays, and the irradiation doses were 5, 10, 20, 50, and 100 kGy. After irradiation with the highest dose of 100 kGy, the sensitivity of the sample with a content of 3 vol. % was reduced to 125. The samples exposed to different irradiation doses were stretched and released 3000 times to verify the repeatability of the force sensitive characteristics; almost no difference was found in the resistance strain results of the sample. Experiments showed that the designed composite force-sensitive structure had high sensitivity, good repeatability, and good resistance to gamma radiation.

Top predator fish, such as peacock bass (Cichla kelberi) and red-bellied piranha (Pygocentrus nattereri), were introduced in the lacustrine system of the Rio Doce basin and these introductions are associated with loss of aquatic biodiversity. The present work aims to investigate the life-history traits of a native species, thraira (Hoplias malabaricus), in the context of the pressures caused by the introduction of top predator fishes. Two lakes were selected in a conservation unit Doce River State Park (PERD), namely, Lake Carioca, where P. nattereri and C. kelberi were introduced, and Lake Gambazinho, where H. malabaricus occurs in the absence of introduced fish. In total, 146 specimens of H. malabaricus were caught, including 95 in Lake Gambazinho and 51 in Lake Carioca. Significant differences were found in the length–weight relationship (LWR) in the diet, the reproductive period, the vitellogenic follicle size, and the gonadosomatic index (GSI). In the lake with introduced species, thrairas showed allometric growth, a less diversified diet, longer duration of the reproductive period, and high GSI values compared with the control lake. The results indicated that the life-history traits of thrairas can be influenced by the environmental modification caused by the introduction of non-native peacock bass and red-bellied piranha.

Vegetation is the only component that can be directly managed to reduce the negative consequences of wildland fires. Flammability indexes provide information about plant flammability characteristics and are commonly used in wildland fuel management. However, previous flammability indexes were usually based on only two or three flammability components. We propose an advanced approach for leaf flammability index estimation that integrates all four flammability components (ignitability, combustibility, sustainability and consumability) using cluster and linear discriminant analyses. We measured time to ignition, ignition temperature, maximum flame height, combustion time, mass loss percentage and fuel moisture content of 15 plant species most affected by forest fires in Turkey (every two weeks, from May to September). Species were divided into different flammability classes and ranked according to their flammability index (FI) values. Classifications and FI rankings showed seasonal variations for some of the species. During May and June, fuel moisture contents explained ~50–60% of variation in leaf flammability but this relationship steadily decreased towards September (13%) when weather conditions became drier. The proposed approach for FI estimation offers a more detailed flammability assessment and comparison between plants. It can be used to identify less flammable plants for fuel breaks and landscaping in the wildland–urban interface.
Lexical, exegetical, and frequency-based analyses of the translations of the Qur’anic collocations
Authors: Qassem Mutahar
Published: February 2022

Translating collocations is one of the problematic areas in translation studies, which becomes even more
complicated when translating Qur’anic text is involved. The uniqueness of Qur’anic linguistic features, special context of the Qur’anic
text, and stylistic differences between English and Arabic are barriers to accurate and natural rendition. Along these veins, this
study attempts to investigate seven translations of the Qur’anic noun-noun collocations (Sarwar 1981; Al-Hilali and Khan 1996;
Arberry 1996; Pickthall 1997; Sahih International 1997; Shakir 1999; Ali 2001) to unfold the degree of accuracy and naturalness of
their translations. The present article follows the approach of corpus-based research to study seven prominent translations of the
Noble Qur’an taken from
The Qur’anic Arabic Corpus
, using lexical,
exegetical, and frequency-based analyses, which reveal that integrated lexical and exegetical analyses are perquisites for
adequate rendition and prevent deviation in meaning and translation loss. Frequency-based approach in translation of collocations
could assist in maintaining naturalness of rendition to some extent.
How Essential is Kratom Availability and use during COVID-19? Use Pattern Analysis Based on Survey and Social Media Data

Published: February 2022

Background: Kratom, a tree native to Southeast Asia, is increasingly used in Western countries for self-treatment of pain, psychiatric disorders, and mitigation of withdrawal symptoms from drugs of abuse. Because kratom is solely supplied from its native locations, supply shortages during the COVID-19 pandemic may impact the availability of preparations and hence force consumers to change their patterns of use. The aim of this study was to understand if and how COVID-19 was influencing kratom purchasing and use. Methods: Additional questions specific to kratom availability and changes in use during COVID-19 were added to an international online survey with responses collected between January and July 2020. During the same period, kratom-related social media posts to Twitter, Reddit, and Bluelight were analyzed for themes similar to the survey questions. Results: The survey results indicated no changes in kratom use patterns although the sample size was relatively small ( n = 70) with younger consumers reporting a potential issue in obtaining their desired products from their usual sources. The survey respondents identified primarily as non-Hispanic whites (87.1%). Social media themes revolved primarily around quitting kratom during COVID-19, misinformation about the effects of kratom on COVID-19, and other non-COVID-related discussions. While some consumers may increase their kratom dose because of additional stress, a majority of discussions centered around reducing or rationing kratom due to COVID-19 or a perceived dependence. Access to quality kratom products was also a major discussion topic on social media. Conclusions: Kratom use patterns did not change due to COVID-19 but consumers were concerned about potential product shortages and resulting quality issues. Clinicians and public health officials need to be informed and educated about kratom use as a potential mitigation strategy for substance use disorders and for self-treatment of pain.

The Square Kilometre Array (SKA) is the largest radio interferometer under construction in the world. Its immense amount of visibility data poses a considerable challenge to the subsequent processing by the science data processor (SDP). Baseline dependent averaging (BDA), which reduces the amount of visibility data based on the baseline distribution of the radio interferometer, has become a focus of SKA SDP development. This paper developed and implemented a full-featured BDA module based on Radio Astronomy Simulation, Calibration and Imaging Library (RASCIL). Simulated observations were then performed with RASCIL based on a full-scale SKA1-LOW configuration. The performance of the BDA was systematically investigated and evaluated based on the simulated data. The experimental results confirmed that the amount of visibility data is reduced by about 50% to 85% for different time intervals (

Considering the problems of the existing joint group for continuous manipulator, including that it is unrealized to meet the required length of the manipulator and the large bending angle of the joint, a new type of under-actuated linkage joint group is proposed in this paper. The parameterized models of the joint group based on the elastic deformation of the linkage rope and the variable-diameter transmission wheel are established respectively, and the kinematics mapping model of the joint group is derived. Based on the establishment of the model, simulation verification was carried out by applying Adams. Finally, the proposed joint group and kinematics model was verified through experiments. The research results show that the total length of the joint group is 750mm, the maximum movement angle of a single joint in the joint group is greater than 30°, and the maximum movement angle of the joint group is greater than 90°, which improves the maximum movement space and maximum movement angle of the existing joint group. Besides, the joint group can realize the coupling motion of three joints.
Polynomial Phase Signal Denoising Connecting Semantic Information Based on Deep Neural Networks

Published: February 2022

This paper considers the problem of polynomial phase signal (PPS) denoising. To prove that proper use of semantic information can further improve the denoising performance based on deep neural networks, we propose an architecture combining the segmentation network and the denoising network. The vision semantic information is extracted from the segmentation network first. Then, that information connecting the time-frequency representation of noisy signal are fed into the denoising network for reconstructing signal. To effectively apply the semantic information, three connection strategies and the corresponding lower bound are presented and compared. The proposed method does not require the pre-identification of signal noise conditions and is suitable for a wide range of Signal-to-Noise-Ratio (SNR) scenarios. Simulation results demonstrate that the F1 scores of the spectrum segmentation results are over 0.98 and the proposed method connecting vision semantics for PPS denoising tasks outperforms the baseline and state-of-the-art architectures, when the SNR is larger than -8dB.

Ontologies are knowledge structures that serve as the foundation for semantic applications. These semantic artifacts organize and classify knowledge to define the semantic relations among the concepts. Some ontologies are constructed for a single natural language, whereas others are built for dual or multi-natural languages. The goal of this study is to design and implement a mobile educational application to help students learn more effectively and to increase the learner’s acquisition of computational linguistics in the Algorithm domain. The methodology is to develop an application with unique features that can display the terms and the concepts in both Arabic and English languages in two different layouts: a list form and a flashcard form. The created app “ArEnAlg” can generate the terms in the algorithm domain. The major objective of the exercise modules is to examine the user’s knowledge of the concepts in the domain of algorithms. The evaluation results tested three factors: the learner’s enjoyment, the acquisition of the computational linguistics, and the application presentation, which showed that behavioral responses support the purpose of the developed application with a max-min range of 99% -81%.
