Extracting Features of Transient Electric Fields With Fourier And Wavelet Transform–A Case Study Of Lightning Positive Return Stroke
Authors: Sharma Shriram 
Published: February 2021

Frequency domain information were extracted from the time domain electric fields pertinent to the lightning positive return strokes applying Fourier transform and Wavelet transform. The electric field radiated by positive ground flashes striking the sea were recorded at 10 ns resolution at a coastal station to minimize the propagation effects. The frequency spectrum of the electric field of positive return strokes were computed applying the Fourier transform technique in the range of 10 kHz to 20 MHz owing to the fact that this range of frequency is of very much interest to the researchers and design engineers. The amplitude of the energy spectral density decreases nearly as ƒ-1 from 10 kHz to about 0.1 MHz and drops nearly as ƒ-2 up to 8 MHz. Applying the wavelet transform technique, the same positive return strokes are found to radiate in the frequency range of 5.5 to 81 kHz with the average spread distribution of 13.6 kHz to about 30 kHz. From frequency spectrum obtained from the Fourier transform it is difficult to identify as which phase of the return stroke radiates in the higher frequency range and that in the lower frequency range, whereas, one can easily identify from the frequency spectrum obtained with the wavelet transform that ramp portion of the positive return stroke radiates in the larger spectral range as compared to that of initial peak of the return stroke. Also, from the spectral density map obtained from wavelet transform one can easily observe the contribution of each phase in a range of frequency, which is not possible from the Fourier transform technique. Clearly, the wavelet transform is much more powerful tool to extract the frequency domain information of a non-stationary signal as compared to that of Fourier transform.
Using Wavelet Transform To Extract Frequency Content In Electric Field Radiated By Unusual Lightning Activity

Published: February 2021

In this frequency spectrum electric fields radiated by the unusual lightning activities have been computed using the wavelet transform technique. The unusual lightning activities have very recently been identified activities and are very poorly understood among the lightning community. As the electric fields are very recently identified and are measured in time domain, to the best of our knowledge, their frequency content has not been studied as of today. To understand the physics of the discharge mechanism of such events, the frequency domain information plays a significant role. In order to extract frequency domain information from the time domain electric field signatures the wavelet transform technique has been employed. For the purpose, the electric field pertinent to the unusual activity, has been divided into two parts namely main activity and the preceding opposite polarity field change. From the computation, it is found that the opposite-polarity field change radiates energy in the spectral range of 2 kHz to 173 kHz whereas, the main activity predominantly radiates in the frequency range 2 kHz to 162 kHz. Such a wider spectral range that the unusual activities radiate have not been reported for the other known activities such as positive and negative return strokes. Evidently, the unusual events have some unique origin of discharge unlike the known activities. Further, as the unusual events were noticed in the temperate region (Uppsala, Sweden) and Sub-tropical climatic zone (Kathmandu, Nepal), it should have some common source of origin between two regions.
A Socio-pragmatics Study: Flouting of Conversational Maxims Found in “Bence” Traditional Market, Kediri
Authors: Muhyidin Mohammad 
Published: February 2021

The study focuses on the flouting of conversational maxims in one of the traditional markets in Kediri. This study focuses on the types of flouted maxims, and the situations where the flouted maxims cause misunderstanding between the sellers and the buyers in the trade of interaction.
This research is conducted by using a descriptive qualitative approach. The data are utterances between sellers and buyers. The theory which the writer used is based on the theory of Cooperative Principles, proposed by Grice (1975), which establishes four maxims, those are the maxim of quality, the maxim of quantity, the maxim of relation and maxim of manner. The data is collected by recording the conversation in the trade transaction. The data is also collected by noting the conversation and transcript it.
The finding shows that there are many flouted maxims found in interaction practices between the seller and buyer. The writer’s analysis show that all kinds of maxims are flouted mostly buy the seller. Those are maxim of quantity, maxima of quality, maxims of relevance and maxim of manner. Thus, it may happen because between the seller and the buyer do not fulfil the rules of cooperative principles. The writer concludes there are some condition which make the participants in the trade interaction have to flout the maxims. Due to the fact that the conversation still run well without any misunderstanding.

Published: February 2021

Ketika seorang muslim ditimpa penyakit, maka yang pertama dilakukan adalah membangun kesadaran bahwa apa yang menimpanya adalah bagian dari kasih sayang Allah yang termanifestasi dalam bentuk penyakit dalam pandangan manusia. Apa yang menimpa manusia berupa penyakit pada hakekatnya bukanlah sesuatu yang negatif sehingga ia diposisikan sebagai musuh, tetapi sesuatu yang dapat memberi manfaat yang sangat besar pada diri manusia sebagai hamba Allah. Untuk mencapai semua ini, seorang yang sakit harus mampu bersabar agar ia mampu menepis segala hal-hal yang bisa merusak kesabarannya

Published: February 2021

Objective: Non-technical skills training and assessment has been implemented in anesthesia residency training program to improve quality of patient care but have not been properly assessed. We hypothesized that trainees with good knowledge correlated with good cognitive parts of non-technical skills.Methods: Seventy anesthesia residents (24 PGY-1, 24 PGY-2 and 22 PGY-3) were assessed for their knowledge by 180-item MCQs, 5 key-feature essay questions, and 18-station OSCE’s. Subsequently, a perioperative anesthesia crisis situation was set up in the simulation lab for all residents and was video recorded. Non-technical skills were assessed by 2 independent trained raters using Anesthetists’ Non-Technical Skills (ANTS) behavioral markers. The residents’ scores were calculated to find the correlation within the ANTS rating scale.Results: The mean scores of knowledge tests were 164.3 ±18.4 out of 300 [165.5 ±18.0, 154.7 ±16.3 and 173.6 ±16.4 for PGY-1, PGY-2 and PGY-3 respectively]. The mean scores of ANTS was divided into 4 categories (rating scale 1 to 4): task management 2.9 (±0.6), teamworking 3.0 (±0.5), situation awareness 2.9 (±0.8) and decision making 2.8 (±0.7). The knowledge test results moderately correlated with ANTS score in task management, situation awareness and decision making [r=0.382 (p<0.01), r=0.433 (p<0.001) and r=0.350 (p<0.01) respectively] and weakly correlated with the teamworking category (r=0.166, p=0.16).Conclusion: Resident’s scores showed moderate correlation with non-technical skills assessment results in cognitive skills. Non-technical skills are required to be trained and assessed together with knowledge to enhance the patient’s safety and outcome.

Audio-Visual Tools in Science Communication: The Video Abstract in Ecology and Environmental Sciences
Authors: Ferreira Miguel , Lopes Betina , Granado António , Freitas Helena , Loureiro João 
Published: February 2021

In recent years, the use of videos by the scientific community has evolved continuously. Researchers, communicators, and other players are using audio-visual media to reinvent their stories, to deconstruct complex phenomena and to increase the outreach and impact of their scientific publications. An example of this trend is the video abstract: an audio-visual representation of the key findings described in the written abstract. Much of the research in this area is new and focused on content analysis and classification of online science videos. Furthermore, studies with videos and environmental communication are attached to specific topics like climate change. So far, a small fraction of publications has explored the study of the video abstract, its effects, and its potential, as one general scientific area. This paper provides the first characterization of video abstracts in the areas of Ecology and Environmental Sciences. We identified video abstracts in 29 scientific journals, based on impact, representativeness and visibility criteria. A database of 171 videos, from 7 publishers and 17 different video channels was created. Each video was analyzed for different parameters. The analysis considered not only characteristics of each video, but also characteristics from the corresponding scientific papers. Results indicate that between 2010 and 2018 the number of video abstracts increased sevenfold. Despite this growth, there was no solid strategy for disseminating the videos. While most of them are still associated with classic models, such as documentaries, disruptive formats such as animation are the ones that arouse greater interest. Professional shorter videos (2–3 min in length) showed a significantly higher number of daily views and their papers garnered a higher number of citations per day. This data, combined with future qualitative research, will help to develop a model for validating the quality of an Ecology video abstract and provide new insights into the global study of audio-visual communication of science.

Published: February 2021

Background: A variety of regulatory approaches including immune modulation have been explored as approaches to either eradicate antitumor response or induce suppressive mechanism in the glioblastoma microenvironment. Thus, the study of immune-related long noncoding RNA (lncRNA) signature is of great value in the diagnosis, treatment, and prognosis of glioblastoma.Methods: Glioblastoma samples with lncRNA sequencing and corresponding clinical data were acquired from the Cancer Genome Atlas (TCGA) database. Immune-lncRNAs co-expression networks were built to identify immune-related lncRNAs via Pearson correlation. Based on the median risk score acquired in the training set, we divided the samples into high- and low-risk groups and demonstrate the survival prediction ability of the immune-related lncRNA signature. Both principal component analysis (PCA) and gene set enrichment analysis (GSEA) were used for immune state analysis.Results: A cohort of 151 glioblastoma samples and 730 immune-related genes were acquired in this study. A five immune-related lncRNA signature (AC046143.1, AC021054.1, AC080112.1, MIR222HG, and PRKCQ-AS1) was identified. Compared with patients in the high-risk group, patients in the low-risk group showed a longer overall survival (OS) in the training, validation, and entire TCGA set (p = 1.931e-05, p = 1.706e-02, and p = 3.397e-06, respectively). Additionally, the survival prediction ability of this lncRNA signature was independent of known clinical factors and molecular features. The area under the ROC curve (AUC) and stratified analyses were further performed to verify its optimal survival predictive potency. Of note, the high-and low-risk groups exhibited significantly distinct immune state according to the PCA and GSEA analyses.Conclusions: Our study proposes that a five immune-related lncRNA signature can be utilized as a latent indicator of prognosis and potential therapeutic approach for glioblastoma.

BackgroundThis study aims to construct and validate a model based on convolutional neural networks (CNNs), which can fulfil the automatic segmentation of clinical target volumes (CTVs) of breast cancer for radiotherapy.MethodsIn this work, computed tomography (CT) scans of 110 patients who underwent modified radical mastectomies were collected. The CTV contours were confirmed by two experienced oncologists. A novel CNN was constructed to automatically delineate the CTV. Quantitative evaluation metrics were calculated, and a clinical evaluation was conducted to evaluate the performance of our model.ResultsThe mean Dice similarity coefficient (DSC) of the proposed model was 0.90, and the 95th percentile Hausdorff distance (95HD) was 5.65 mm. The evaluation results of the two clinicians showed that 99.3% of the chest wall CTV slices could be accepted by clinician A, and this number was 98.9% for clinician B. In addition, 9/10 of patients had all slices accepted by clinician A, while 7/10 could be accepted by clinician B. The score differences between the AI (artificial intelligence) group and the GT (ground truth) group showed no statistically significant difference for either clinician. However, the score differences in the AI group were significantly different between the two clinicians. The Kappa consistency index was 0.259. It took 3.45 s to delineate the chest wall CTV using the model.ConclusionOur model could automatically generate the CTVs for breast cancer. AI-generated structures of the proposed model showed a trend that was comparable, or was even better, than those of human-generated structures. Additional multicentre evaluations should be performed for adequate validation before the model can be completely applied in clinical practice.

Study designRetrospective cohort study.IntroductionDebates remain regarding the role of lymphadenectomy in patients with apparent stage IA endometrial cancer, especially subtypes with a favorable prognosis. This study aimed to explore the prognostic value of staging surgeries in apparent stage IA endometrial endometrioid cancer patients in a retrospective cohort study.MethodsCases from June 1, 2010 to June 1, 2017 were reviewed in patients with pathologically confirmed endometrial endometrioid carcinoma limited to &lt;1/2 of the myometrium, without extrauterine metastasis on preoperative evaluation and during surgical inspection. Survival outcomes were compared between patients with and without lymphadenectomy and between patients with and without metastasis to lymph nodes.ResultsIn total, 1,312 eligible patients were included, among which 836 underwent staging surgeries and 476 underwent simple hysterectomy. Twenty-eight patients were found with metastasis to retroperitoneal lymph nodes. After a median follow-up of 57.4 months, lost to follow-up, recurrence, death, and cancer-specific death occurred in 28, 39, 24, and 16 patients, respectively. In a univariate analysis, lymphadenectomy of the pelvis with or without para-aortic lymph nodes had no significant impact on disease-free survival, overall survival or cancer-specific overall survival (p values &gt;0.05). However, after adjusting for important baseline risk factors [menopausal status, tumor differentiation, maximum diameter and location, lymph-vascular space invasion (LVSI) status, and postoperative adjuvant therapy), lymphadenectomy resulted in significantly improved survival outcomes (p values &lt;0.05). Menopause (odds ratio [OR] 4.7, 95% confidence interval [CI] 1.3–16.4, p=0.015), tumor diameter larger than 2 cm (OR 4.6, 95% CI 1.3–16.0, p=0.016), grade 3 tumors (OR 3.0, 95% CI 1.0–8.5, p=0.042), positive LVSI (OR 8.7, 95% CI 3.7–20.4, p&lt;0.001) and lower uterine segment involvement (OR 3.1, 95% CI 1.4–7.2, p=0.007) had more extrauterine metastases.ConclusionIn cases of apparent stage IA endometrioid endometrial carcinoma, staging surgeries should be considered in patients with larger, higher grade tumors, positive LVSI, or lower uterine segment involvement.
