ANN-Based DEM Fusion and DEM Improvement Frameworks in Regions of Assam and Meghalaya using Remote Sensing Datasets
Authors: Girohi Priti , Bhardwaj Ashutosh 
Published: August 2022

The Digital Elevation Models (DEMs) are a key and primary input to a large number of modelling processes such as disaster risk monitoring, flood modelling, hydrology, geology, geomorphology, climatology, and environmental study applications. The DEM serves as an important source of topographic information representing the continuous surface of the earth in 3 dimensions with x, y and z coordinates of any point in a grided raster form or a vector TIN form. This study is based on developing a new method using the universal approximation capability of neural networks for the fusion and improvement of L-band and X-band SAR (Synthetic Aperture Radar) DEMs in the complex terrain of Assam and Meghalaya states of the Indian geographic region using the DEM fusion technique. The high-spatial-resolution ALOS PALSAR RTC HR 12.5 m DEM products are used in a fusion framework designed with neural network models. The network adaptively learns the terrain information to produce fused DEM products. The neural network models generate the relationship between the input elevation information from ALOS PALSAR DEMs and precise reference elevation from ICESat-2 spaceborne altimetry as target data. The training and testing data samples are prepared and filtered by checking the correct range of elevation from the toposheets of this region. Different models are used to separately train for the relatively plain valley portion of the Assam region and mountainous portions of the highland Shillong plateau. The obtained fused DEMs from the developed neural net structure are assessed for their quality and accuracy by estimating the RMSE parameter. The fused DEM attains an RMSE value of 7 meters for the complete region which is a significant improvement over the input DEM RMSE of approximately 11 meters. The plain area points and mountainous region points are assessed separately to analyze the predictions from neural nets in the two types of terrains observed in this study site. Moreover, TanDEM-X 90 m DEM is improved using the neural network modeling in the geometric distortions affected areas, which shows an improvement of around 33% overall at the study site. The assessment of plain and mountainous region points for near-ground points shows an improvement of 47% and 55% respectively. The fusion framework designed using the neural network models is an effective and efficient method for obtaining fused DEMs as well as for the improvement of the existing DEMs for complex terrain.

Published: August 2022

Background: Ectopic pregnancy is a clinical condition where a fertilized ovum implants outside the endometrium of the uterine cavity. Worldwide, ectopic pregnancy complicates 0.25-2.0% of all pregnancies. High index of suspicion of the clinical triad; abdominal pain, amenorrhea and vaginal bleeding is very important for its early detection and management.

Objectives: To determine the prevalence, clinical presentations, sites, risk factors and outcomes of ectopic pregnancy in a tertiary health institution in Umuahia, Nigeria.

Materials and Methods: This retrospective study was conducted in the Department of Obstetrics and Gynaecology, Federal Medical Centre, Umuahia over a period of 10years from January 2011 to December 2020. The records of patients with ectopic pregnancy were traced through the main theater, ante-natal clinic, and the records unit. All information obtained were coded, entered into and analyzed using IBM SPSS version 25.

Results: A total of 268 patients with ectopic pregnancies were studied out of 19,535 gynecological cases and 13,901 deliveries within the study period. This gave a prevalence of 1.4% of all gynecological cases and 1.9% of all deliveries. Ectopic pregnancies occurred more in women between 26 and 35years of age (54.9%). The commonest symptoms seen were abdominal pain (24.7%), Amenorrhea (22.7%) and vaginal bleeding (22.1%). The commonest sites of occurrence were fallopian tube 244 (91.1%), intramural (3.4%) and cervical ectopic pregnancy (2.2%). All the patients were managed surgically while 84% had ruptured uterus. Risk factors observed were a history of PID (30.0%), previous ectopic pregnancy (14.6%), infertility (12.5%), IUCD placement (12.1%) and previous abortion (11.2%).

Conclusion: Ectopic pregnancy is one of the leading causes of maternal morbidity and mortality for women of reproductive age. Early diagnosis and management in form of medical treatment or conservative surgery not only reduces maternal morbidity and mortality but also preserves future fertility.

Published: August 2022

Abstract

Introduction
Septic arthritis after arthroscopy (SAAA) is a devasting complication which reported frequency varies about 0.04%–5.7%. The aim of the study is to analyze frequency of SAAA at one orthopedic center, risk factors and accuracy of actual prophylactic measures.

Materials and Methods
A retrospective study (level of evidence: V) includes 794 (665 primary and 129 revision) “clean” arthroscopies performed in the years 2017–2018 with confirmed joint infection during 30 days after operation without the use of non-resorbable implants and up to 1 year after procedures with non-resorbable implants. Demographic and medical data about potential risk factors of SAAA were analyzed: patients age, sex, operated joint, type of procedure, primary or revision procedure, the use of drains, usage of non-absorbable implant, time of surgery, BMI, time lapse from index operation to diagnosis of SAAA, length of hospital stay, causative microorganisms. All operations were performed by eight different but experienced surgeons, in operation theatre with vertical laminar flow with the capacity of 50 air exchanges per hour. The perioperative antibiotic prophylaxis consisted of one preoperative dose 1 g cefazolin in simple arthroscopies, which was prolonged to 24 hours with 3 doses in cases of implantation of non-absorbable implant (55.8% of patients).

Results
From 794 cases 4 have been infected: 2 after knee arthrolysis, one after ACL reconstruction and one after rotator cuff repair. There were 2 early, with manifestation within 30 days, and 2 late-onset SAAA. Infections occurred in 0.5% of all arthroscopies and in 0.47% of knee arthroscopies alone. Patients age and time of surgery have not been found significantly different in infected and non-infected cases, whereas age and time of surgery have been significantly different in revision and non-revision cases.

Conclusions
Primarily aseptic arthroscopic procedures performed with respect to actual perioperative preventive measures have a low risk of postoperative septic arthritis. The risk increases with patients age and time of operation, but not significantly.

Published: August 2022

Abstract
Based on the strong classification feature recognition algorithm, the calculation algorithm of a text semantic similarity is studied with the performance evaluation in this paper. In order to achieve a general algorithm for this function, the semantic function library based on a semantic recognition code as a comparison object is designed. It drives the algorithm modules of two fuzzy neuron deep convolution machine learning, and between these two processes of machine learning, a rigid algorithm based on Fourier transform frequency domain feature is extracted. Finally, a more complex machine learning general algorithm is realized by the use of external data fuzzy algorithm and de-fuzzy algorithm before and after the algorithm module. It is also a technical innovation in this paper. Through the performance evaluation based on the subjective evaluation of volunteers, it is found that the system focuses on the text semantic similarity evaluation of the Chinese language, and achieves a comparison result of 81.78% of the artificial judgment accuracy rate, and only 5.52% of the volunteers believe that the system judgment result is completely different from that of manual judgment.

Abstract

Introduction
The use of invasive mechanical ventilation (IMV) in COVID-19 represents in an incremental burden to healthcare systems.

Aim of the study
We aimed to characterize patients hospitalized for COVID-19 who received IMV and identify risk factors for mortality in this population.

Material and Methods
A retrospective cohort study including consecutive adult patients admitted to a private network in Brazil who received IMV from March to October, 2020. A bidirectional stepwise logistic regression analysis was used to determine the risk factors for mortality.

Results
We included 215 patients, of which 96 died and 119 were discharged from ICU. The mean age was 62.7 ± 15.4 years and the most important comorbidities were hypertension (62.8%), obesity (50.7%) and diabetes (40%). Non-survivors had lower body mass index (BMI) (28.3 [25.5; 31.6] vs. 31.2 [28.3; 35], p<0.001, and a shorter duration from symptom onset to intubation (8.5 [6.0; 12] days vs. 10 [8.0; 12.5] days, p = 0.005). Multivariable regression analysis showed that the risk factors for mortality were age (OR: 1.07, 95% CI: 1.03 to 1.1, p < 0.001), creatinine level at the intubation date (OR: 3.28, 95% CI: 1.47 to 7.33, p = 0.004), BMI (OR: 0.91, 95% CI: 0.84 to 0.99, p = 0.033), lowest PF ratio within 48 hours post-intubation (OR: 0.988, 95% CI: 0.979 to 0.997, p = 0.011), barotrauma (OR: 5.18, 95% CI: 1.14 to 23.65, p = 0.034) and duration from symptom onset to intubation (OR: 0.76, 95% CI: 0.76 to 0.95, p = 0.006).

Conclusion
In our retrospective cohort we identified the main risk factors for mortality in COVID-19 patients receiving IMV: age, creatinine at the day of intubation, BMI, lowest PF ratio 48-hours post-intubation, barotrauma and duration from symptom onset to intubation.

Published: August 2022

Abstract
Plant-parasitic nematodes (PPN) are harmful pests that have become a severe threat to crop production worldwide. Diversity of PPN at horizontal and spatial scales influence the effectiveness of control strategies. This study evaluated the vertical distribution of PPN genera at 0 cm to 30 cm and 30 cm to 60 cm in sweet potato fields in Central, Manyatta, and Nembure regions of Embu County, Kenya. A significant region × depth interaction was observed for Tylenchus. For all the other nematode genera, there were no significant variations in the abundance at 0 cm to 30 cm and 30 cm to 60 cm depths. However, Helicotylenchus, Meloidogyne, and Scutellonema occurred in greater numbers at both depths in all regions. Shannon and Simpson diversity indices were higher at 0 cm to 30 cm depth while Pielou’s evenness was similar at both depths in the three regions. Diversity partitioning of genus richness, Shannon, and Simpson diversities across all regions at 0 cm to 30 cm, indicated that β component contributed 61.9%, 35.6%, and 22.6% of γ diversity, respectively. Coinertia analysis indicated a significant covariation between nematode genera and soil properties. The results show that management of PPN in sweet potato fields should be targeted at soil depths that are not less than 60 cm.
EVOLUTIONARY PATTERNS OF GENOME SIZE AND CHROMOSOME NUMBER VARIATION IN BEGONIACEAE
Authors: Campos-Dominguez Lucia , Pellicer Jaume , Matthews Andrew , Leitch Ilia J , Kidner Catherine A 
Published: August 2022

Cytological data resources are crucial to the study and understanding of the evolution of complex taxa. Recent research on the genus Begonia L. has provided a robust phylogenetic background for the analysis of evolutionary patterns across the group and has established that Begonia is variable in genome size and chromosome number. This paper provides an overview of the genome structural variation present in Begonia and an updated chromosome number and genome size dataset for the genus. Chromosome numbers of more than 400 species are presented and discussed within their current taxonomic and phylogenetic context. A more complete chromosome number dataset is available for Neotropical and Asian Begonia sections than for those from Africa. The distribution of chromosome numbers across phylogenetic trees supports the idea of Begonia sections as natural groups, because most variation is found between sections rather than within them. Some larger Begonia clades were found to have larger chromosome number variation. Moreover, groups with the most variable chromosome numbers belong to some of the taxonomically complex or unresolved Begonia sections. Genome size variation was found not to correlate with changes in chromosome number. It suggests that Begonia genome dynamics are caused not only by large-scale duplications, rearrangements, and changes in ploidy levels but also by changes in the repetitive fraction of the genome, which probably cause changes in chromosome size. This could potentially play an important role in species radiations.

Authors: Handoyo Ardi Wisnu , Thomas Daniel 
Published: August 2022

The Begonia diversity of the northern arm of Sulawesi and the adjacent Sangihe Talaud Islands, Indonesia, is reassessed, and distribution maps, proposed IUCN conservation category categories, and an identification key to 22 recognised species are presented. Three new species, namely Begonia kinhoi, B. pitopangii and B. sojolensis, are described and photographs provided. Newly available material allowed a reassessment of the morphological variability of several species that were originally described from very limited material (Begonia carnosa, B. cuneatifolia, B. gemella, B. hispidissima, B. masarangensis, B. mendumiae and B. strachwitzii), and revised descriptions and photographs of these species are provided. Begonia heteroclinis is reduced to synonomy of B. carnosa, and both names are lectotypified. Additionally, recircumscription and revised synonymy of Begonia rieckei are presented.

Fraud in Tegal Bedug Hamlet occurred several times, such as fraud in the form of fraudulent investments, the departure of illegal migrant workers and there was also hypnosis-based fraud. Lack of knowledge of anti-fraud toughness makes them not aware of the impact and how to overcome it if fraud occurs. Often people in rural areas do not find out more about the modus operandi of fraud, they always believe in lucrative things because of economic and job demands. Psychoeducation is used to benefit the people of Dusun Tegal Bedug in terms of providing education and mental strength in the future. Implementation of the anti-fraud resilience program counseling as a form of psychoeducational activity provided to community participants in collaboration with Tegal Bedug Hamlet, Indramayu. To see the benefits of the anti-fraud resilience program to the community, we give the pre-test and post-test and an interviews also were conducted after the activity. The results obtained indicate that community participants benefit from information about resilience in fraud, reduced victims, and increased curiosity about the characteristics of fraud. This program also has benefits as a mental psychoeducational activity for the community as an effort to improve the quality of life in rural communities ABSTRAK:Penipuan di Dusun Tegal Bedug terjadi beberapa kali, seperti penipuan yang berupa investasi bodong, pemberangkatan TKI ilegal dan ada juga penipuan berbasis Hipnotis.
