Abstract
Background
Granulomatosis with polyangiitis (GPA) is a syndrome of refractory vasculitis in the upper respiratory tract, lungs, kidneys, and systemic small and medium-sized arteries; adults and children have similar courses. A pediatric GPA case with a preceding bloody pericardial effusion, which caused cardiac tamponade, and bloody stool has not been reported.
Case presentation:
A 14-year-old boy was referred for the evaluation of prolonged fever. He had chest pain and bloody stools, and diagnostic imaging showed a pericardial effusion. Immediately after admission, his systolic blood pressure decreased (85/70 mmHg), and pericardiocentesis was performed, with aspiration of approximately 500 mL of bloody pericardial fluid. Because pericardiocentesis increased the blood pressure (115/65 mmHg), the cause of the blood pressure decrease was diagnosed as cardiac tamponade. Because the pericardial fluid cytology was negative for malignant disease, as were chest MRI and gallium scintigraphy, colonoscopy was performed and showed multiple irregular-shaped aphthae from the right transverse colon to the cecum on the contralateral side of the mesenteric attachments, and a biopsy of the aphthous region showed necrotizing granulomatous inflammation. The patient also had an elevated serine proteinase 3-anti-neutrophil cytoplasmic antibody (PR3-ANCA) level (141 IU/mL) on serological examination. Head MRI showed thickening of nasal and sinus mucosa and a cystic mass in the left sphenoid sinus. Therefore, GPA was diagnosed based on these findings, and treatment with oral prednisolone (PSL) and azathioprine was started. After the treatment, the bloody stool disappeared, and there was no recurrence of pericardial effusion even after completing PSL tapering, and the PR3-ANCA level was maintained in the normal range.
Conclusions
Although pericarditis is a common cardiac complication of GPA, there have been no previous reports of cardiac tamponade due to pericarditis. This is the first case of a pediatric patient with cardiac and gastrointestinal complications preceding the main symptoms, including upper and lower respiratory tract and renal symptoms, although cases of GPA with bloody stools are extremely rare. In conclusion, the sequencing of measuring ANCA levels appears important assuming the vasculitic syndrome as one of differential diseases causing persistent fever and bloody stool including such as the inflammatory bowel disease.
An Efficient Parallel Block Compressive Sensing Scheme for Medical Signals and Image Compression
Authors: Chakraborty Parnasree , C Tharini 
Published: June 2021

Abstract
With rapid development of real-time and dynamic application, Compressive Sensing or Compressed sensing (CS) has been used for medical image and biomedical signal compression in the last decades. The performance of CS based compression is mostly dependent on decoding methods rather than the CS encoding methods used in practice. Many CS encoding and decoding algorithms have been reported in literature. However, the comparative study on performance metrics of CS encoding with block processing and without block processing is not investigated by the researchers so far. This paper proposes block CS based medical images and signals compression technique and the proposed technique is compared with standard CS compression. The proposed algorithm divides the input medical images and signals to blocks and each block is processed parallel to enable faster computation. Three performance indices, i.e., the peak signal to noise ratio (PSNR), reconstruction time (RT) and structural similarity index (SSIM) were tested to observe their changes with respect to compression ratio. The results showed that block CS algorithm had better performance than standard CS based compression. More specifically, the parallel block CS reported the best results than standard CS with respect to less reconstruction time and satisfactory PSNR and SSIM.

Abstract
An ovoid to rod shaped, white tobrown pigmented, facultative anaerobic, mesophilic, non-phototrophic, Gram-staining-negative, non-motile, multiply by binary fission designated strain KVB23T, which was isolated from root of rice plant, near Ilsan, South Korea, was investigated for its taxonomic position by polyphasic approach. Optimal growth was found to occur at 30˚C, at pH 6.5 and in the absence of NaCl on R2A. Phylogenetic analysis based on the 16S rRNA gene sequence of strain KVB23Trevealed that it formed a distinct lineage, as a separate deep branch within the family Rhodobacteriaceae, with <96.5% sequence similarity to representatives of the genera Rhodobacter, Xinfangfangia, Tabrizicola, Falsirhodobacter, Haematobacter, Paenirhodobacter, Pseudorhodobacter and Pararhodobacter. Based in 16S rRNA sequences strain KVB23T was most closely related to Tabrizicola fusiformis KCTC 62105T (96.5%) and Rhodobacter thermarumKCTC 52712T(96.2%).The draft genome of strain KVB23Twas 3.80 bp long with a DNA G + C content of 63.1 %. Genome of strain KVB23T harboured gene clusters for tryptophan and cobalaminbiosynthesis. The strain contained Q-10 as the sole respiratory quinone. The predominant fatty acids were found to consist of C16:0, C18:0 and summed feature 8 (comprising C18:1 ω7c and / or C18:1 ω6). The polar lipids were identified as diphosphatidylglycerol, phosphatidylethanolamine,seven unidentified phosphoglycolipids, two unidentified aminophosphoglycolipid, one unidentified glycolipid and four unidentified lipids.Phosphate-solubilizing bacteria have the ability to dissolve insoluble phosphates and enhance the soil fertility. Strain KVB23Tcan solubilize calcium phosphate tribasic. Phosphate solubilizing and tryptophan biosynthesis property of strain KVB23T could be a possible factor for the increase in growth of rice plant. Differential phenotypic, chemotaxonomic and genotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain KVB23T was found to represent a novel genus in the Rhodobacteriaceaefamily, for which the name Fuscibacteroryzae gen. nov., sp. nov. is proposed, with the type strain KVB23T(=KACC 21711T =NBRC 114716T).

Abstract
Background: This study aim to evaluate surgical procedures for titanium plate internal fixation of costal cartilage fractures with displacement or nonunion. Methods: From January 2019 to October 2020, 13 patients with costal cartilage fractures were treated with titanium plate internal fixation in the thoracic surgery department of the Shanghai Sixth People’s Hospital. Pain severity scale scores and respiratory function were evaluated preoperatively and postoperatively. All the patients had a 6-month follow-up for treatment evaluation. Results: The mean hospital length of stay was 10.7 days. A statistically significant difference (P < 0.05) was found between preoperative and postoperative pain severity scores( 7.69 vs. 5.00). VC (24.6% vs. 44.5%) and FEV1 (25.3% vs. 44.0%) were also significantly different before operation and after operation (P<0.05). At follow-up, healing of the nonunion or fracture was confirmed in all the cases. Conclusion: The rigid titanium plate application ensured a safe and easy management of costal cartilage fractures and nonunion with a good prognosis as compared with other methods.

Abstract
The prevention of detrimental effects to environment, owing to generation of a huge amount of rubber wastes, is a big challenge across the globe that warrants a thorough investigation of recycling and reuses waste of rubber products. In this spirit a sustainable development of a devulcanization process along with the production of value added devulcanized rubber is a task of hours. The present work describes a simultaneous devulcanization and chemical functionalisation process of waste solution styrene butadiene rubber (S-SBR). This kind of rubber is generally used as the main polymer component in silica filled tread rubber compounds for high-performance passenger car tyres. As-grown ethoxy groups on the functionalized devulcanized styrene butadiene rubber (D-SBR) are exploited for the coupling between silica and the devulcanized rubber chains. We compare the mechanical and dynamic mechanical performance of D-SBR with that of virgin SBR control composites. Covalently bonding interfaces developed from the pendent ethoxy groups of D-SBR and silanol groups on the silica surface offer a competitive and promising performance of the D-SBR based composites. We conclude that the present approach can be further utilized for the large-scale production of different rubber products with satisfied elastomeric performance.

Abstract
Background: To evaluate the accuracy of distinct diabetes mellitus (DM) screening methods in persons with active Tuberculosis PWTB.Methods: Levels of fasting plasma glucose (FPG) and glycated hemoglobin (HbA1c) at the time of tuberculosis diagnosis at the study clinics were assessed from two distinct retrospective cohorts of PWTB from Brazil (n=116) and Peru (n=136) to evaluate accuracy for detecting pre-DM and DM cases. Additionally, we investigated the association of clinical and sociodemographic factors with tuberculosis and pre-DM or DM in each country.Results: When comparing PWTB from Brazil and Peru, Peruvian individuals presented higher FPG levels at baseline (median [IQR] 91 [81–106 vs 95 [88.4–102.1]]; p=0.02), while those from Brazil had significant higher levels of HbA1c (median [IQR] 6.3 [5.7-7.15] vs 5.1 [4.9-5.4]; p<0.01). Additional analysis using the receiver operating characteristic curve revealed that the markers showed distinct accuracy to identify dysglycemia among PWTB in each country. Conclusion: Our findings indicate that there are significant differences in the total accuracy of the glycemic screening methods evaluated between PWTB from two highly endemic countries from South America, highlighting the need to revisit the diagnostic criteria of DM/PDM in individuals with tuberculosis.
A Knowledge Discovery Method for Landslide Monitoring Based on K-core Decomposition and the Louvain Algorithm

Published: June 2021

Abstract
Landslide monitoring plays an important role in predicting, forecasting and preventing landslides. Quantitative explorations at the subject level and fine-scale knowledge in landslide monitoring research can be used to provide information and references for landslide monitoring status analysis and disaster management. In the context of the large amount of keyword co-occurrence network information, it is difficult to clearly determine and display the domain topic hierarchy and knowledge structure. This paper proposes a landslide monitoring knowledge discovery method that combines the K-core decomposition and Louvain algorithms. In this method, author keywords from the literature are used as nodes to construct a weighted co-occurrence network, and a pruning standard value is defined for K. The K-core approach is used to decompose the network into subgraphs. Combined with the unsupervised Louvain algorithm, subgraphs are divided into different topic communities by setting a modularity change threshold, which is used to establish a topic hierarchy and identify fine-scale knowledge related to landslide monitoring. Based on the Web of Science, a comparative experiment involving the above method and a high-frequency keyword subgraph method for landslide monitoring knowledge discovery is performed. In the resulting 5-core network subgraph of landslide monitoring keyword co-occurrence, 17 community structures can be identified, and the degree value and density of subcommunities are analysed by taking the community with the largest proportion of nodes as an example. The results show that the retention time of the proposed method is significantly lower than that of the traditional method.

Abstract
In the last decade, the interest in software-defined ultra-wideband (UWB) and tunable radio frequency (RF) apparatuses with low size, weight, and power consumption (SWaP), has grown dramatically, pushed by the new 6G vision where, RF equipment shall enable a large number of fundamental applications as UWB communications, robot localization mapping and control and high precision radars, all of them contributing in revolutionizing our life style.
Unfortunately, the coexistence of ultra-wideband and software-defined operation, tunability and low SWaP represents a big issue in the current RF technologies.
In this article, to the best of our knowledge, the first example of a complete tunable software-defined RF transmitter with low footprint (i.e. on photonic chip) is presented exceeding the state-of-the-art for the extremely large tunability range of 0.5-50 GHz without any parallelization of narrower-band components and with fast tuning (<200micros). This first implementation, represents a breakthrough in microwave photonics.

Abstract
Neurons in the developing brain undergo extensive structural refinement as nascent circuits adopt their mature form1. This transformation is facilitated by the engulfment and degradation of excess axonal branches and inappropriate synapses by surrounding glial cells, including microglia and astrocytes2,3. However, the small size of phagocytic organelles and the complex, highly ramified morphology of glia has made it difficult to determine the contribution of these and other glial cell types to this process. Here, we used large scale, serial electron microscopy (ssEM) with computational volume segmentation to reconstruct the complete 3D morphologies of distinct glial types in the mouse visual cortex. Unexpectedly, we discovered that the fine processes of oligodendrocyte precursor cells (OPCs), a population of abundant, highly dynamic glial progenitors4, frequently surrounded terminal axon branches and included numerous phagolysosomes (PLs) containing fragments of axons and presynaptic terminals. Single- nucleus RNA sequencing indicated that cortical OPCs express key phagocytic genes, as well as neuronal transcripts, consistent with active axonal engulfment. PLs were ten times more abundant in OPCs than in microglia in P36 mice, and declined with age and lineage progression, suggesting that OPCs contribute very substantially to refinement of neuronal circuits during later phases of cortical development.
Molecular triggers of symptoms of parosmia and insights into the underlying mechanism
Authors: Gane Simon , Parker Jane , Kelly Christine 
Published: June 2021

Abstract
The molecular stimuli that trigger a parosmic response have been identified. Parosmia is a debilitating condition in which familiar smells become distorted and unpleasant, frequently leading to clinical depression. Often a result of post infectious smell loss, incidences are increasing as COVID-19 cases escalate worldwide. Until now, there was little understanding of its pathophysiology, and the prevailing hypothesis for the underlying mechanism is a mis-wiring of olfactory sensory neurons. However, with novel application of flavour chemistry techniques as a relatively rapid screening tool for assessment of both quantitative and qualitative olfactory loss, we identified 15 different molecular triggers in coffee. This provides evidence for peripheral causation, but places constraints on the mis-wiring theory. Furthermore, it provides the basis for development of a practical diagnostic tool and treatment strategies.
Performance of Gridded Precipitation Products in the Black Sea Region for Hydrological Studies
Authors: SWALIH SEAD AHMED , Kahya Ercan 
Published: June 2021

Abstract
Gridded precipitation products are becoming good alternative data sources for regions with limited weather gauging stations. In this study, four climate gridded precipitation products were utilized, namely: Climate Forecast System Reanalysis (CFSR), European Centre for Medium-Range Weather Forecasts (ECMWF) ERA-Interim/land, the Asian Precipitation-Highly-Resolved Observational Data Integration Towards Evaluation of Water Resources (APHRODITE), and Multi-Source Weighted-Ensemble Precipitation (MSWEP). The key novelty of this study is to fill the gap in one of important areas of the transcontinental region of Eurasia, namely Rize province in the Black Sea region being selected as a study area since it has complex topography and climatology in addition to a limited number of gauging stations. A set of precipitation products were assessed for performance with the observed precipitation data before using a hydrological model (SWAT) to evaluate the basin response for the climate products. Three methods were considered in this study: (i) spatial comparison; (ii) hydrological, and (iii) statistical evaluation. Along with precipitation forcing, the SWAT model simulations were analysed in conjunction with streamflow observations. In an overall evaluation, the percentage bias of ERA-Interim/land, CFSR, APHRODITE, and MSWEP mean monthly precipitation is 19.9%, 33.4%, 41.4% and 85.0% respectively. For the flow simulations, the CFSR and MSWEP have resulted in exaggerated peak flows in the high flow season due to overestimated precipitation forcing (Nash Sutcliffe efficiency [NS] equal to 0.22 and -0.73, respectively). On the contrary, the APHRODITE underestimated the peak flows due to lower precipitation estimates (NS = 0.38). The ERA-Interim land showed good agreement with the observed flows (NS = 0.53). From these readings we stated that the ERA-Interim land exhibited improved performance with the observed precipitation whereas the CFSR showed the worst performance. The study suggests that gridded precipitation products could supplement observed precipitation data for observational data scarcity in mountainous regions.

Published: June 2021

Abstract
The reduction potential of the highly toxic Cr(VI) to the inert Cr(III) in an alkaline soil was studied during a 50-day experiment with Portulacaoleracea grown in pots. We aimed at assessing whether our test species can be a phytoremediation candidate for Cr(VI)-contaminated soils. We measured the Cr(VI) reduction rate in soil, determined the Cr(VI) and Cr(III) concentrations in aerial and root P. oleracea tissues, calculated the Transfer coefficient (TC=metal in plant over metal in soil) and the Translocation factor (TF=metal in aerial biomass over metal in roots) in order to assess Cr(VI) uptake and distribution in plant tissues, while we also studied the effect of added nitrogen in the studied parameters. We added five different Cr(VI) levels,reaching 148.6 mg Cr(VI) kg-1soil and also had two N levels (equivalent to 0 and 200kg ha-1). The results indicated that Cr in plant tissues was mainly found in its reduced form (Cr(III)) and only a minor fraction of Cr was detected in its oxidized form (Cr(VI)). The main remediation mechanism was found to be that of the naturally occurring Cr(VI) reduction that effectively produced Cr(III), followed by the uptake of Cr(VI) from our test plants. We also found that Cr(VI) in P. oleracea tissues was mainly found in roots and relatively low Cr(VI) concentrations were found in the above ground tissues. We concluded that P. oleraceais a tolerant plant species, especially if assisted with a sufficient level of N fertilization, although it failed to approach the threshold of being categorized as an accumulator species.However, before reaching more conclusive suggestionsabout P. oleracea as a potential phytoremediation species, further investigation is necessary.
An Energy Efficient Resource Allocation and Transmit Antenna Selection Scheme in mm-Wave Using Massive MIMO Technology
Authors: Singh Charanjeet , Kishoreraja P C 
Published: June 2021

Abstract
The massive Multiple-Input Multiple-Output (MIMO) improves the reliability of transmission and capacity of the channel. Resource allocation (RA) and Transmit Antenna Selection (TAS) can minimize the complexity in implementation and hardware costs. In this research, both the RA as well as the TAS of wireless communication in millimetre- wave (mm-wave) with massive MIMO technology is considered. Two different solutions are developed for this research such as the Deep Learning method for efficient resource allocation process and optimization algorithm for Transmit Antenna Selection (TAS) process. Here, the RA process is done with the help of Attention Based Capsule Auto-Encoder (ACAE) architecture which allocates the radio resources like power, space, time and frequency to all the available users in the system. Further, Battle Royale Optimization (BRO) algorithm is utilized to select an efficient antenna from multiple antennas at BS. This optimization algorithm optimally selects an efficient antenna so that, user equipments (UEs) can create high quality links and achieves a reduced power consumption rate of the whole architecture. The overall system performance depends on the selection of optimal antenna which in terms enhances Spectral Efficiency (SE), Energy Efficiency (EE), reliability, and diversity gain of MIMO technology. In this way, both RA and optimal antenna selection schemes are performed to maximize the overall performance of wireless communication with massive MIMO technology for 5G wireless communication applications. The implementation of the proposed methodology is evaluated on MATLAB. Finally, the efficiency of the developed method is improved with respect to the capacity, EE and SE.
