An Initial Exploration of Tweets Associated With Web Accessibility
Authors: Alim Sophia , Ismail Abid
Published: October 2022

The issue of web accessibility is prevalent in society. However, few studies have looked at social interactions on Twitter associated with the issue. Sentiment analysis and readability analysis were used to assess the emotions reflected in the tweets and to determine whether the tweets were easy to understand or not. In addition, the relationship between the features of the tweets and their readability was also assessed using statistical analysis techniques. A total of 11,483 tweets associated with web accessibility were extracted and analysed using sentiment and statistical analysis. For readability analysis, 200 randomly selected tweets from the dataset were used. Sentiment analysis highlighted that overall, the tweets reflected a positive sentiment, with ‘trust' being the highest-scoring emotion. The most common words and hashtags show a focus on technology and the inclusion of various users. Readability analysis showed that the 200 selected tweets had a level of reading difficulty associated with the readability level of college students.
An Intelligent System for the Diagnosis of Voice Pathology Based on Adversarial Pathological Response (APR) Net Deep Learning Model
Authors: Mittal Vikas , Sharma R. K.
Published: October 2022

The work investigates the use of two types of glottal flow derivative-based image variants of the input signal with an n-dilated (nD)-inception-layers-based deep learning model for providing optimal labels. The authors have proposed an n-dilated (nD) inception layer-based adversarial pathological response (APR) net deep learning model. This model is trained using the two image databases separately in an adversarial manner so that when a test image is common to test image is applied to both the networks. The results show a mean accuracy of 96.82%, 96.36%, and 99.35% for the Glottal inverse filtering with extended Kalman Filter-Morse scalogram (GIFEKF-MS) APRNet, Glottal inverse filtering with extended Kalman Filter-spectrogram (GIFEKF-S) APRNet, and proposed APR fusion net respectively using the VOice ICar fEDerico II (VOICED) dataset; and mean accuracies 95.67%, 93.27%, and 99.04% for the GIFEKF-MS APRNet, GIFEKF-S APRNet, and proposed APR fusion net respectively using the Saarbrucken voice database (SVD)dataset.

Published: October 2022

As sharing digital media is getting more prominent, there has been a rise in the development of techniques for protecting digital media against misuse. However, the amount of such techniques has been less prominent for printed goods. The data hiding method presented in this paper is suited for the print domain. The method uses the Discrete Fourier Transform to embed data into images and Gray Component Replacement to maintain high image quality by masking embedding artifacts. This research examines whether the method's performance can be optimized using low-frequency ranges for embedding. The aim is to evaluate the usage of low-frequency ranges in order to achieve higher robustness. Different frequency ranges are tested to determine how they affect image quality and detection rates. Tests are conducted in the digital domain. The results show that the method can maintain image quality regardless of the frequency range, and that low-frequency ranges lead to more consistent detection rates. Future research will be done on images in the print domain.

Published: October 2022

This work is concerned the tensile properties of the secondary Ni-based single-crystal superalloy DD6 near [001] orientation at 760°C. In this study, anisotropic tensile properties of DD6 alloy within 10° of the [001] orientation were exhibited at 760°C. The yield strength and ultimate tensile strength of DD6 alloy oriented close to [001] direction was the highest. As the deviation off the [001] orientation increased, both 0.2% yield strength and ultimate tensile strength was decreased. The specimens oriented close to [001]-[111] boundary exhibit higher yield strength and ultimate tensile strength than the specimens oriented close to [001]-[011] boundary. Numerous of dislocations can be found in the γ matrix channels during the tensile deformation. A number of dislocation pairs and few of stacking faults are found in the γ' precipitates after the tensile at 760°C. The morphology of γ' phases in DD6 alloy maintained cubical during the tensile deformation at 760°C. With Schmid's Law, the mechanism of anisotropic tensile properties in DD6 alloy near [001] orientation is analyzed.

Authors: Yang Qiang , Yang Chang Hao , Ma Kai , Zhang Xia Oli , Chen Hai Feng , Ren Han
Published: October 2022

In order to verify the bearing performance of Mg-Li alloy thread connections, the tightening performance and axial pull-out performance of the Mg-Li alloy thread structure with wire thread insert were tested, and the failure load and mode were obtained. The finite element 2D axisymmetric model was used to numerically analyze the bearing properties of Mg-Li alloy threads. The reliability of the analysis model was verified by comparison with the experimental results and theoretical basis. The load distribution and stress distribution characteristics of the thread connection were studied, and the influence of boundary constraints on the axial pull-out performance was studied. The results show that the M5 Mg-Li alloy embeded wire threat insert with 8 rounds has sufficient connection strength under the action of tightening torque and axial pull-out load, and the failure mode is mainly bolts fracture. Boundary constraints will have an influence on the load distribution and performance of the Mg-Li alloy thread connection structure. The load-bearing ratio of each round thread changes obviously with the downward movement of the top of the boundary. As the top of the boundary moves downward, the location where the maximum load-bearing ratio will be transformed from the first thread to the last thread. The load-bearing ratio of the last thread gradually increases from 11.3% when the outer circumference fully restrained to 23.1% when the boundary area below 4 mm from the last thread. For the M5 Mg-Li alloy embeded wire threat insert with 8 rounds, the axial pull-out bearing capacity of M5 inserts is between 9.5 kN and 12 kN under different boundary conditions.

Organisational politics - a prerequisite perspective for general management
Authors: MacMillan I. C.
Published: October 2022

Die skrywer se doel met hierdie artikel is om (a) 'n politieke model van organisatoriese gedrag te ontwikkel en (b) aan te toon wat die implikasies van so 'n politieke model is vir die ontwikkeling van sakebestuurders se vaardigheid in algemene bestuur. Hy ontleed aanvanklik die politieke handeling van die individuele deelnemer aan die organisasie, waarop 'n ontleding van die politieke optrede van interne sowel as eksterne groepe volg. Die struktuur van politieke optrede in 'n organisasie word dan in verband gebring met die beleidvormingsproses. Hieruit spruit voort 'n politieke model van organisatoriese handeling wat gedrag in organisasies sien as synde gevorm deur die eise van interne en eksterne invloedryke en magsgroepe wie se ondersteuning behou moet word indien die organisasie wil voortbestaan. So 'n model vermy die begrip van 'n alwetende, "rasionele" besluitnemer aan die hoof van 'n organisasie; dit vereis eerder dat die algemene bestuurder moet erken dat sy rol die is van 'n leier van 'n politieke organisasie. lndien so 'n model geldig is, het dit uiteraard verreikende implikasies vir die op!eiding van bestuurders, nl. die ontwikkeling van 'n politieke perspektief, 'n analitiese vermoë, 'n herkenning van die politieke effek van beperkte hulpbronne, vaardigheid in die gebruik van die tegnieke van veralgemening van en opeenvolgende aandag aan beleidsbesluite, vaardigheid om politieke vooroordeel of partydigheid te herken, en 'n vermoë om die implikasies van besluite te kan deurdink.

Authors: Patil Pavitra , Dhulkhed Pavan Vithal , Dhulkhed Vithal K.
Published: October 2022

We aimed to assess whether ropivacaine (0.75%; 22.5 mg) can replace bupivacaine (0.5%; 15 mg) as a better intrathecal anesthetic in lower abdominal surgery. In this hospital-based, single-blind, randomized, prospective, comparative study, 100 patients of either sex, aged between 18 and 70 years, weighing 40-80 kg, with American Society of Anesthesiologists physical status 1 and 2, and undergoing lower abdominal surgery were randomly allocated into two groups to receive intrathecal isobaric bupivacaine 0.5% 3 mL (15 mg) or ropivacaine 0.75% 3 mL (22.5 mg). In the intraoperative period, the onset, efficacy, duration, and regression of sensory and motor blockade and the quality of anesthesia and hemodynamic effects were observed at regular intervals. The ropivacaine and bupivacaine groups were comparable for demographic parameters. The duration of onset of sensory and motor blocks was significantly shorter in the bupivacaine group (P < 0.01). In the ropivacaine group, a faster recovery from sensory block (P = 0.02) and higher segmental height [thoracic (T)10 and T8] were achieved (P < 0.01). Bradycardia and hypotension were insignificant in the ropivacaine group (P > 0.05). Isobaric ropivacaine is a better spinal anesthetic in lower abdominal surgeries as it provides faster recovery from sensory block and a higher level of segmental sensory block with fewer side-effects.

Published: October 2022

The novel coronavirus disease 2019 is caused by coronavirus and has been seen to cause fatal pneumonia complicated by severe respiratory distress syndrome. Until February 22, 2022, according to the Ministry of Health and Family Welfare, Government of India, there were 181,075 active COVID cases with 4,218,510 discharged patients and 512,344 deaths. As a part of primary prevention, vaccines have been launched, administrated, and under development along with several drugs that are being investigated for treatment and prophylaxis in COVID-19 infection. The World Health Organization conducted SOLIDARITY, a vast scale study and laid down names of potential drugs that can be used in the management of COVID-19 infection including chloroquine (CQ) phosphate, hydroxychloroquine (anti-malarial) Remdesivir, Lopinavir-Ritonavir with or without interferon (anti-HIV), and convalescent plasma therapy. It has also been known that coronavirus has inflammatory pathogenesis which is responsible for the cytokine storm especially in individuals that are susceptible and with coexisting morbidities. This has led to the consideration of anti-inflammatory cytokine drugs including Anakinra and Tocilizumab, the efficacy of which has also been studied in the management of COVID-19 infection. The current evidence of efficacy regarding two particular approaches to the management of COVID-19 are being elaborated in this review article: Immunomodulators and biological therapy. The article critically discusses therapeutic effectiveness and efficacy of immunomodulator drugs for the management of COVID-19 including CQ, 2-deoxy-d-glucose, and biological therapies such as Tocilizumab, zinc, interferon, plasma therapy, and monoclonal antibodies. In addition, immune-altering conditions related to rheumatology and especially tuberculosis has been discussed to a certain need for change in the management of both.

Authors: Athar Abdul Mateen , Suleman Kothi Zuber , Davis Deepak , Begum G. Ayesha Siddiqua
Published: October 2022

Background:

Atrial fibrillation (AF) being the most common arrhythmia encountered clinically is associated with increased mortality and morbidity. Hence, this study was conducted to find the clinical profile, etiology, and echocardiographic factors of AF for the secondary prevention of known complications.

Materials and Methods:

This was an observational hospital-based study done on 60 patients with AF in the Department of Medicine, St. John's Medical College Hospital, Bengaluru, India.

Results

Out of 60 patients with AF, the mean age was found to be 63 years in our study. Female sex (61.67%) had more preponderance to AF than male sex (38.33%). The most common presenting complaint was breathlessness (50%), followed by asymptomatic (25%) and palpitations (21.6%). Surprisingly, a significant number of patients were asymptomatic (25%) during the episode of AF. Hypertension (58.3%) was found to be more prevalent than rheumatic heart disease (RHD) (31.6%) in our patients, the most common complications were noted as heart failure (45%) rather than cerebrovascular accident (CVA) (15%). Nonvalvular AF (68.33%) exceeded the number of patients with valvular AF (31.66%). Ten percent of our subjects had dilated left atrium and 30% of our subjects had ejection fraction of <50%. The most common valvular lesion was found to be mitral regurgitation (45%) followed by mitral stenosis (28.3%).

Conclusion

This study has provided insight into the changes in trends pertaining to the clinical profile of AF. The most common predisposing condition is hypertension rather than RHD. Although the most common presenting complaint was breathlessness, there was a significant subset of individuals who were asymptomatic during the AF episode. A significant number of individuals had heart failure and CVA as complications of AF.

Authors: Prajapati Kesar Vinodbhai , Gandhi Archana U. , Rathod Malay Mukeshbhai , Patel Mihir Hareshkumar , Patel Savan , Patel Tapan
Published: October 2022

Background:

Cardiovascular diseases (CVDs) are the major culprit to cause morbidity in type 2 diabetes mellitus (T2DM) patients. Endothelial dysfunction (ED) precedes the progressed stage of CVD presentation. This study aimed to study the risk factors for ED and identify the modifiable factors for risk reduction and provide caution measures.

Materials and Methods

This cross-sectional observational study included 100 adult patients with T2DM on oral hypoglycemic drugs or insulin therapy. Based on glycemic control, type 2 diabetic patients were divided into four groups: Group 1 (poor glycemic control and hemoglobin A1C (HbA1c) >9%), Group 2 (fair glycemic control and HbA1c 8%–8.9%), Group 3 (good glycemic control and HbA1C 7–7.9%), and Group 4 (excellent glycemic control, HbA1C <7%). P < 0.05 was considered statistically significant.

Results

Overall, significantly higher glycemic levels (fasting blood glucose, postprandial blood glucose, and HbA1c) and lipid derangements (cholesterol, low-density lipoprotein, and triglyceride) were found in patients with ED as compared to those without ED (P < 0.05). Baseline brachial artery diameter (D1) was into three groups, one group with D1 (≤3.6 mm) with mean flow-mediated dilatation (FMD) of 9.07%, Another group of D1 (3.61 mm to ≤4.30 mm) with mean FMD of 5.26%, and the third group with D1 (>4.41 mm) with mean FMD of 4.58%. There was a statistically significant association seen between baseline brachial artery diameter and FMD (P < 0.05). Multivariate linear regression showed that HbA1c and treatment of both Oral hypoglycemic agents (OHA) and insulin were the significant independent factors affecting the ED with OR of 7.566 (P = 0.0003) and 0.013 (P = 0.011), respectively.

Conclusion

In diabetics, the risk of ED is increased with worsening levels of lipid profile and glycemia irrespective of the age and duration of the disease.

Authors: Suresh Roopa , Reddy Sanjay , Naidu Y. R. , Reddy Y. J. , Dhananjaya P. E. , Jaganath A.
Published: October 2022

Background:

Type II respiratory failure is a common complication with considerable morbidity and mortality. Noninvasive ventilation (NIV) has been used preferentially with better results. The objective of this study was to assess the outcome and complications of NIV in type II respiratory failure patients.

Methods

A clinical observational study of 67 consecutive adult patients with Type II respiratory failure who were assigned NIV, fulfilling inclusion and exclusion criteria were recruited in the study. NIV Bi level positive airway Pressure (Bi PAP) (spontaneous mode) was used in all patients with settings of 12/6 initially. Based on arterial blood gas values and clinical status, settings were adjusted and followed up as per British Thoracic Society guidelines (2016). In case of worsening of mental status, deterioration of potential of hydrogen (PH), increased partial pressure of carbon dioxide, and intolerance to NIV, patients were subjected to invasive ventilation within the first 4 h of NIV initiation.

Results

Patients diagnosed with acute exacerbation of chronic obstructive pulmonary disease (–92.5%), and cases of obstructive sleep apnea (7.5%), showed significant improvement in NIV trial over 24 h in 91.7% and 100%, respectively, by the way of reduction of PCO2 levels and improvement in partial pressure of oxygen, oxygen saturation, which was statistically significant in 89.5% of patients. Clinical improvement noted by the decrease in heart rate, respiratory rate was also statistically significant with a P < 001. However, PH did not show significant changes in our study.

Conclusions

A trial of NIV is a useful alternative to mechanical ventilation in many different situations with Type II respiratory failure. Advantages of cost-effectiveness, minimal utilization of intensive care unit resources, low morbidity and mortality rates with patient-friendly equipment features contribute to its preference over invasive ventilation.

Прямое доказательство теоремы Шталя для некоторого класса алгебраических функций
Authors: Suetin Sergey Pavlovich
Published: October 2022

В предположении о существовании $S$-компакта Шталя приводится короткое доказательство существования предельного распределения нулей полиномов Паде и сходимости по емкости соответствующих диагональных аппроксимаций Паде для некоторого достаточно общего класса алгебраических функций. Приведенное доказательство прямое, а не методом от противного, как это сделано в оригинальных работах Шталя. Ограничение на класс алгебраических функций означает, в частности, что все критические точки римановой поверхности рассматриваемой функции второго порядка (т.е. все ветвления алгебраической функции квадратичные). В качестве следствия для рассматриваемого класса алгебраических функций доказана справедливость одной из гипотез Гончара, связанных с аппроксимациями Паде.
При доказательстве не используется свойство ортогональности, справедливое для полиномов Паде; оно основано только на принципе максимума.

Гарантированный детерминистский подход к суперхеджированию: соотношение "детерминистской" и "вероятностной" постановок при отсутствии торговых ограничений
Authors: Smirnov Sergei Nikolaevich
Published: October 2022

Для задачи суперрепликации с дискретным временем рассматривается гарантированный детерминистский подход: задача состоит в гарантированном покрытии обусловленного обязательства по опциону при всех допустимых сценариях. Эти сценарии задаются при помощи априори заданных компактов, зависящих от предыстории цен: приращения цены в каждый момент времени должны лежать в соответствующих компактах. Предполагается отсутствие транзакционных издержек. Постановка задачи носит теоретико-игровой характер и приводит к уравнениям Беллмана-Айзекса как в чистых, так и в смешанных стратегиях "рынка". В предположении отсутствия торговых ограничений изучается вопрос, как связаны между собой функции Беллмана для "детерминистской" и "вероятностной" постановок задачи суперхеджирования. При весьма общих условиях "вероятностная" функция Беллмана не превосходит "детерминистскую". Найдены достаточные условия совпадения этих функций.

Derin Öğrenme Metodu ve Ayrık Dalgacık Dönüşümü Kullanarak BT Görüntülerinden Akciğer Kanseri Teşhisi
Authors: CİFCİ Mehmet Akif
Published: October 2022

Derin Öğrenmenin (DÖ) teknikleriyle erken kanser tanısı son dönemlerde araştırmacılar arasında en çok üzerinde durulan konu olmuştur. Ayrıca pek çok araştırmada görüldüğü üzere DÖ’nın tıp alanında kullanımı günümüzde daha da önem kazanmaktadır. Araştırmacılar sağlık alanında çoğunlukla kanser ve kanser türleri teşhis ederken DÖ tekniklerinden yararlanmaktadır. Bunun başlıca nedeni akciğer kanserinden ölüm riskinin yüksek olmasıdır. Bu tür hastalıkların tanısında BT görüntülerinin net olmamasından dolayı, doğru karar vermede uzmanlar görüş ayrılıkları yaşamaktadır. Bu ve benzeri hastalıkları erken ve doğru tanılayabilen ve daha güvenilir sonuçlar verebilen DÖ karar verme mekanizmaları bir seçenek haline gelmiştir. Yapılan araştırmalara göre akciğer kanseri, dünya çapında ölümlerin en önde gelen nedenleri arasındadır. Akciğer kanseri sadece 2019 yılında tahmini 1,76 milyon insanın ölümden sorumludur. Sebepleri artıkça (ortalama aile öyküsü, sigara, yüksek tansiyon ve diğer popüler tıbbi nedenler) ölüm oranı ortalaması %80'in üzerinde arttığı gözlemlenmiştir. Olgular erken tanı konup, tedavi edilirse kanser kaynaklı ölümlerin oranının azalmakta olduğu görülmüştür. Hastalığın doğru saptanması tedavi edilmesinde önemli rol oynamaktadır.

Bu çalışmada Ayrık Dalgacık Dönüşümü (ADD) yaklaşımı ile DÖ tekniği birleştirilerek, 6053 akciğer tomografi veri seti (veri kaynağı, yaş grubu, coğrafi bölge vb. kısa bilgi) üzerinde işlem yapılmıştır. Hastanın kanser olup olmadığı, kanser olduğu takdirde ise bunun iyi huylu (benign) ya da kötü huylu (malign) olduğuna karar verilmesine çalışılmaktadır. Bilgisayarlı Tomografi (BT), görüntülerde öncelikle görüntü işleme aşamalarının yanı sıra ADD ile öznitelik çıkarımı yapılıp elde edilen veriler DÖ ’ya girdi verisi olarak kullanılır. Bu çalışmada iki metot önerilmiştir. Birinci yöntemde VGG-16, Inception v4, MobileNet v3 kullanılırken ikinci yöntemde AlexNet yöntemi uygulanmaktadır. Bu yöntem hem ADD kullanımı hem de iki aşamalı olması yönüyle yaygın kullanılan diğer tekniklerden farklıdır. Deneysel sonuçların yüksek performans gösterdiğini ve AlexNet’in %99, 86, MobileNet v3’ün %98,00, VGG-16 %95,50, Inception v4’ün ise %96,03 doğrulukta sonuç verdiği belirlenmiştir. Böylece akciğer hastalıklarının BT görüntülerinde kanser olup olmadığı, kanser ise hangi aşamada olduğu konusunda ön bilgi elde edilebilmektedir.

Published: October 2022

The demand for water resources is increasing day by day due to the rapid increase in the world population, drought caused by industrialization, urbanization and global climate change. The efficient use of water resources depends on the correct planning and operation of the water resources systems of the future. The seasonality analysis is to reveal the similarities between the hydrological characteristics of the currents regionally. Examining the seasonality of river flow data is essential for the correct design and efficient operation of the hydraulic structures to be designed. In this study; the seasonal similarity of low and high stream flows throughout the year was determined by using the daily flow data of 5 flow streamflow gauging stations selected at certain geographical points of the Kızılırmak basin. The similarity of the basins was determined by using the seasonal statistics calculated and the direction of the average occurrence dates for each station. This observed similarity was also associated with the hydrological similarity between stations and the hydrological characteristics of the basins were found.

Poultry meat containing low fat and high protein is an important and economical protein source in providing the animal protein requirement for human nutrition. The frequent emergence of poultry diseases such as avian influenza is the feature of fast-spread in farms seriously threatens both the economy and human health. In this study, neural network (NNs) models are proposed for the classification of broiler chickens as healthy and sick for earlier detection of poultry diseases. The NNs used in the classification are artificial neural network (ANN), adaptive neuro-fuzzy inference system (ANFIS), and support vector machine (SVM). In the literature, the data set which includes seven visual features were acquired through the IPTs and was used for training, testing, and validating the process of NN models. The results point out that, the computer vision-based application using NNs is successfully classified the broilers in terms of their health conditions.

Wildfire susceptibility mapping can be affected by several factors. One of the most influential factors is inventory data, its extent, format, and reliability. This study aims to evaluate if the Support Vector Machine (SVM) has the capability to detect and map the forest fire susceptible areas under limited training data conditions. To test this hypothesis wildfires in Mugla province located in the Eastern Mediterranean Region of Turkey have been selected as a pilot study area. The wildfire started in Mugla, on 29 July 2021, that considerably affected the residential areas, animals, and vast areas of forests. Fourteen wildfire influential variables have been used in the analysis as independent variables. Accuracy assessment has been implemented using the Area Under the Curve (AUC) technique. Success rate and prediction rates were (91.42%) and (87.69%) respectively. According to the prediction rate, SVM successfully recognized other burnt areas as the most susceptible regions.
