Mind maps are visual frameworks suchÂ as Â figures, diagrams, or Â charts usedÂ to Â present structural knowledge spatially with the intention of empowering comprehension and learning. Mind maps are effective in terms of helping communicate information because they can clarify complex concepts into simple, meaningful displays so that learners can develop a holistic understanding of the content to be learnt. Teachers may use mind mapping technique at Â different Â stages Â of Â instructionÂ for Â example during Â instructionÂ to Â prepare Â students to approach new Â information andÂ clarify complex ideas, or Â after instruction to Â assess Â and reinforce learning and instruction. This article reports on an investigation into the use of mind mapping technique whether it can improve reading comprehension ability and the studentsâ€™ opinions towards the use of mind mapping technique. The research design used in this study was one-group pre test-post test design. The study employed both quantitative and qualitative data analyses from pre-and post-tests, a questionnaire, and an interview. The participants of the Â studyÂ were Â 35 Â first-year Â students Â enrolling Â in Â a Â compulsory reading Â course Â called Communication and Reading Skills at Darussalam Polytechnic of Palembang.Â Â Fifteen students (5 highly successful, 5 who did not show any improvement, and 5 unsuccessful) were selected for retrospective interviews. The results suggested that 1) The English reading comprehension post test mean score of students was higher than the pre test mean score at the 0.05 level of significance; 2) most students were satisfied with their own reading comprehension ability; 3) they enjoyed working in Â group and Â agreed that Â mindÂ mapping technique was Â a Â useful technique and can be applied to non- English subjects. Findings and implications for further research are discussion.

Authors: Al-Khafaji Khitam R. 
Published: May 2023

Back ground: Gastrointestinal Stromal Tumors (GISTs), although are rare, are the most common mesenchymal tumors of the digestive system. Vascular endothelial growth factor(VEGF) is associated with the malignant potential of several types of carcinomas.
Patients, material, and methods: This is a retrospective study including thirty two randomly selected cases of GISTs collected from the pathology laboratory of the gastroenterology and hepatology teaching hospital and from private laboratories from the period January 2010 to December 2013. VEGF immunohistochemical marker was applied to the tumor tissue sections to evaluate its expression and to correlate it with other parameters.Objectives: to evaluate the expression of VEGF in GIST and its correlation with different clinic- pathologic parameters and risk categories.
Results: The mean age of the patient was 42.5 years with a female to male ratio of 1.3:1. The stomach was the most common site for the tumor. VEGF was expressed in 12(37.5%) cases. There was a significant statistical correlation between overexpression of VEGF and the patients' gender and the primary tumor site. There was no significant statistical correlation between VEGF overexpression and age of the patients, size of the tumor, mitotic index, and risk of malignant potential categories.
Conclusion: There is a significant statistical correlation between VEGF expression and both gender of the patients, and the primary site of GIST.
Waterlettuce Weevil Neohydronomus affinis Hustache, 1926 (Insecta: Coleoptera: Curculionidae)
Authors: Telmadarrehei Telmah , Minteer Carey R. 
Published: May 2023

Neohydronomus affinis Hustache is known as the waterlettuce weevil (Figure 1). It is a biological control agent of the floating plant, waterlettuce, Pistia stratiotes Linnaeus (Araceae) (O’Brien & Wibmer, 1989; Center et al., 2002). Waterlettuce is found in tropical and subtropical regions of the world. It infests slow-moving streams, waterways, lakes, and rivers, forming dense floating mats that are composed of several rosettes connected by stolons (runner stems). The presence of waterlettuce mats diminishes biological diversity and generates obstructions for boating, waterflow, and aquatic organisms (Cordo & Sosa, 2000; Dray & Center, 2002). Even though waterlettuce was documented by explorer William Bartram in Florida before 1765 (plants-archive.ifas.ufl/plant-directory), it is listed as a class II prohibited aquatic plant in the State of Florida.
There are three species in the genus Neohydronmus, all of which originate from South and Central America. These weevils are subaquatic, and their exoskeletons are covered in white scales with no water-resistant features. The three species are all associated with waterlettuce and feed exclusively on it (Center et al., 2002; O’Brien & Wibmer, 1989). Among them, N. affinis was first introduced as a biological control agent into Florida in 1987 at Torry Island and Kreamer Island at the south end of Lake Okeechobee (Dray et al., 1990; 2001). Since then, the insect has successfully established itself in peninsular Florida and is also reported in Louisiana (Center et al., 2002).
Targeted Self Supervision for Classification on a Small COVID-19 CT Scan Dataset
Authors: Ewen Nicolas , Khan Naimul 
Published: May 2023

<p>Traditionally, convolutional neural networks need large amounts of data labelled by humans to train. Self supervision has been proposed as a method of dealing with small amounts of labelled data. The aim of this study is to determine whether self supervision can increase classification performance on a small COVID-19 CT scan dataset. This study also aims to determine whether the proposed self supervision strategy, targeted self supervision, is a viable option for a COVID-19 imaging dataset. A total of 10 experiments are run comparing the classification performance of the proposed method of self supervision with different amounts of data. The experiments run with the proposed self supervision strategy perform significantly better than their non-self supervised counterparts. We get almost 8% increase in accuracy with full self supervision when compared to no self supervision. The results suggest that self supervision can improve classification performance on a small COVID-19 CT scan dataset. Code for targeted self supervision can be found at this link: <a href="https://github.com/Mewtwo/Targeted-Self-Supervision/tree/main/COVID-CT" target="_blank">this https URL</a> </p>
GRIHA: synthesizing 2-dimensional building layouts from images captured using a smart phone
Authors: Goyal Shreya , Khan Naimul , Chattopadhyay Chiranjoy , Bhatnagar Gaurav 
Published: May 2023

<p>Indoor scene reconstruction and generating a 2D/3D floor plan is a widely explored problem. In the recent years a few algorithms have been proposed, which either use RGB-D images, requiring a depth capturing camera or depend upon panoramic images, assuming little to no occlusion in the room. In this work, we propose a framework named GRIHA (Generating Room Interior of a House using ARcore), which takes advantage of RGB images taken from a conventional mobile phone camera. The proposed work uses Simultaneous Localization And Mapping (SLAM) technology to estimate the 3D transformations required for layout generation. GRIHA uses SLAM based Google ARcore library for camera pose estimation while capturing the images. It gives the user freedom to generate a layout by merely taking a few conventional photos, rather than relying on specialized depth hardware or occlusion-free panoramic images. We have compared GRIHA with other existing methods and obtained superior results. Moreover, the system is tested on multiple hardware platforms to test the dependency and efficiency.</p>
