Authors: Zakhary Ibrahim , Alani Hasanain , Firouzi Tara , Ditmyer Macia , Ahmad Maha 
Published: October 2023

Abstract
Background: A mandatory preclinical suture laboratory was implemented as part of the Oral Surgery course where students were trained and allowed to practice various suturing techniques on cadavers under direct supervision of an oral surgeon. The primary purpose of this study was to evaluate the students’ perception of the effectiveness of this lab experience in preparing them for performing sutures during their oral surgery rotations.
Methods: The second year dental students during 2014/2015 participated in a preclinical suturing lab.
Suturing techniques were demonstrated to students by an oral surgeon, immediately followed by practice sessions. Students received formative feedback and the opportunity to repeat any procedure to ensure they were subsequently able to perform the techniques properly. Following their Oral Surgery rotation, students were asked to complete an electronic survey about their preclinical simulation lab experience. They rated how important they felt this simulation lab was to performing suturing correctly, whether the simulation lab was properly aligned in the curriculum, the course design and implementation of the simulation lab, time allocated for the session and practice, whether the didactic portion complement the preclinical lab portion, and overall impression of the simulation lab experience.
Results: Students who received the preclinical simulation lab suture training reported that they were more comfortable and confident in performing suturing
techniques in their surgical rotations. Students also reported that it would be helpful having more practice sessions available.
Conclusion: The laboratory was effective in preparing the pre-doctoral students at the right time of the program to perform various suture techniques prior to starting oral surgery rotations.
Subnanometric Platinum–Germanium Clusters Break the Activity–Stability Tradeoff in Propane Dehydrogenation
Authors: Furukawa Shinya , Nakaya Yuki 
Published: October 2023

Abstract
Propane dehydrogenation has been a key technology with great industrial promise for meeting the growing global demand for propylene. Although much effort has been devoted to developing ideal catalysts that demonstrate high catalytic activity, selectivity, and durability at the same time, there have been no reports on the achievement of this goal due to a tradeoff between activity and selectivity/stability. Herein, we report that subnanometric Pt–Ge alloy clusters encapsulated in pure silica MFI zeolite break the activity–stability tradeoff in propane dehydrogenation. We also discovered that MnOx could act as an efficient co-catalyst to reach the full potential of Pt–Ge alloy clusters by preventing hydrogen poisoning. The MnOx-PtGe@MFI catalyst exhibited exceptionally high catalytic activity, selectivity, and durability in the absence of co-fed hydrogen at 600°C, exceeding those of other reported catalysts. Mechanistic study revealed that the combination of subnano-downsizing and Ge doping to Pt was the origin of the exceptional performance, and anti-sintering ability provided by the zeolite cage was not a key to the great enhancement of catalyst stability.
Cultural divergence in Sujata Bhatt’s poem “Search for My Tongue”
Authors: Ahamed Nachiya S. 
Published: October 2023

This research paper deals with the culture object in Sujata Bhatt’s poem “SEARCH FOR MY TONGUE”. Sujatha Bhatt was born in Gujarat and immigrated to the United States. The persons who admire poetry are aware of what’s going around the world which gives muse to write poems, and sometimes they write poem that connect those to their culture. The present study depicts the life of immigrants who experience the specific tension. Like the speaker Sujata Bhatt, they try to adjust their life in a new country, without forgetting where they come from(native). Sujata also explores how immigrants must often negotiate between supposedly irreconcilable cultural identities, their own, and that of dominant culture which they belong. It also slides on how the dominant culture can threaten to erode an immigrant’s identity. People migrate primarily for social and economical reasons that causes a wide gap between the culture and traditions they follow. Being an Indian, the poet tells her trauma of adapting herself to a new culture. “Search for my tongue” is a poem by Sujata Bhatt, here, the poet includes English and Gujarati lines. Bhatt herself as an immigrant explores how hard it is to adapt to a new culture. The pressure of assimilation and the association between the language and identity fades the native culture. The poet tells her second language overtakes her mother language, the loss of native language would be a loss of her heritage and sense of self- identity which can diminish the culture. Towards the finish of the poem, she witnesses herself, that her primary language had a quality to tie a bunch on her second, going to be her local language appears to have revived her. The euphoric finish of the poem reaffirms the association between language, personality, and self articulation proposing that by utilizing her native language, the speaker has recovered a piece of herself from migration and absorption. She likewise proposes other immigrants, to build up another far off character that incorporates both of their social and cultural experiences.
Creating automatic passwords and patterns based on image processing from back hand wrinkles
Authors: Mariasamy A 
Published: October 2023

Passwords, Patterns and Finger prints are a ubiquitous part of the present age. They are the keys to unlock our online profiles, bank accounts, mobile phones, iPad, opening money Box (safe) which is hosted across a plethora of websites and other electronic devices. With each of our profiles necessitating a separate password, it is not uncommon for people to need up to 50 passwords. Recent events have now seen hundreds to millions of passwords leaked in online, more than one hundred million LinkedIn logins and tens of millions of Twitter logins were made available on the darknet. This paper aims at proposing a novel objective approach which utilizes wrinkles on the back four fingers of the human to create patterns or passwords automatically using randomization by extracting the four fingers back wrinkles using sensors then merging all four fingers’ wrinkles together and make the system to create pattern or password without known by the user or any human beings. Each and every time the same wrinkles group is detected it creates and changes new passwords. This cannot be known to anyone. This can be done through image enhancement and morphologic methods through wrinkle retrieval. We identify the pixels of the image of wrinkles and label them as letters for each and every pixel of a particular finger wrinkles and give decimal values from the ASCII table. We merge all four finger tables and start creating randomized patterns using Boolean Expression. The methodology is explained below.

Published: October 2023

BackgroundTikTok is a popular social media platform that allows users to create and share content through short videos. It has become a place for everyday users, especially Generation Z users, to share experiences about their reproductive health. Owing to its growing popularity and easy accessibility, TikTok can help raise awareness for reproductive health issues as well as help destigmatize these conversations.ObjectiveWe aimed to identify and understand the visual, audio, and written components of content that TikTok users create about their reproductive health experiences.MethodsA sampling framework was implemented to narrow down the analytic data set. The top 6 videos from each targeted hashtag (eg, #BirthControl, #MyBodyMyChoice, and #LoveYourself) were extracted biweekly for 16 weeks (July-November 2020). During data collection, we noted video characteristics such as captioning, music, likes, and cited sources. Qualitative content analysis was performed on the extracted videos.ResultsThe top videos in each hashtag were consistent over time; for example, only 11 videos appeared in the top 6 category for #BirthControl throughout the data collection. Most videos fell into 2 primary categories: personal experiences and informational content. Among the personal experiences, people shared stories (eg, intrauterine device removal experiences), crafts (eg, painting their pill case), or humor (eg, celebrations of the arrival of their period). Dancing and demonstrations were commonly used in informational content.ConclusionsTikTok is used to share messages on myriad reproductive health topics. Understanding users’ exposure provides important insights into their beliefs and knowledge of sexual and reproductive health. The study findings can be used to generate valuable information for teenagers and young adults, their health care providers, and their communities. Producing health messages that are both meaningful and accessible will contribute to the cocreation of critical health information for professional and personal use.

As discussões e perspectivas concernentes à tópica da curiosidade assumiram importância e interesse no pensamento hespérico na medida em que, ao se encontrarem imbricadas com o desejo de conhecer, pulsão humana pela investigação, acabaram por transbordar do campo da ética para outras regiões do conhecimento como para a epistemologia, a psicologia e a filologia, desvelando, assim, inegável potência interdisciplinar e pluralidade cultural.
De nossa parte, agregada à tradicional pertinência do tema, constatamos, após levantamento preliminar da literatura crítica, do quão escassamente tal matéria (nas áreas e períodos aqui reunidos) se faz representar nos periódicos brasileiros. Sobretudo, os artigos que compõe o presente Dossiê da Revista Territórios & Fronteiras refletem e questionam acerca dos aspectos históricos, filosóficos e culturais que são mobilizados na polissemia de sentidos e nas ambiguidades valorativas da curiosidade e do curioso em seus múltiplos desdobramentos. Pretendem, pois, proporcionar fecundo contato com a literatura consolidada sobre o tema, e, indo além, oferecer interpretações sobre as variadas faces da curiosidade e do curioso em distintos cenários.

Kepemimpinan Perempuan di Jawa Timur dalam Perspektif Keputusan Muktamar, Munas, dan Konbes Nahdlatul Ulama (1926-1999 Masehi)
Authors: Ellyda Retpitasari  , Nailal Muna  
Published: October 2023

Problematika gender merupakan bagian isu dan tema sentral yang tidak luput dari pembahasan di masyarakat. Perempuan yang berada pada posisi dipimpin, semenjak kebijakan era reformasi yang memberi ruang pada perempuan memunculkan kepempimpinan perempuan. Penelitian ini menggunakan metode kualitatif dengan pendekatan fenomenologi mencoba untuk menganalisa Kepemimpinan perempuan di Jawa Timur dalam perspektif Keputusan Muktamar, Munas, dan Konbes Nahdlatul Ulama (NU) (1926-1999 Masehi). Kesetaraan gender dalam fenomena kepempimpian perempuan di Jawa Timur diketahui dari perbandingan jumlah kepala daerah perempuan dan laki-laki di Jawa Timur dengan presentase laki-laki 77,6% dan perempuan22,3%. Perempuan yang diusung menjadi kepala daerah dalam hal ini bukan semata sebagai pendamping atau objek untuk menarik minat masyarakat memilih akan tetapi memiliki kesamaan dengan pemimpin laki-laki dengan kompetensi dalam memimpin dan latar belakang pendidikan serta pengalaman berorganisasi yang mumpuni. Akan tetapi tetap saja ditemukan indikasi ketidaksetaraan gender dalam kepemimpinan perempuan di Jawa Timur, dari 17 pempimpin perempuan dirinci hanya 7 orang yang menduduki kursi sebagai bupati/walikota sedangkan jumlah perempuan yang menduduki kursi sebagai wakil bupati/walikota berjumlah 10 orang. Kedudukan perempuan yang mana dalam kepemimpinan hanya sebagai wakil bupati/walikota mengindikasikan ketidaksetaraan gender. Indikasi ketidaksetaraan gender diketahui dari perempuan sebagai obyek dari system politik yang dibangun secara sepihak oleh kaum laki-laki. Akan tetapi di era reformasi saat ini dapat terlihat keberhasilan kepemimpinan perempuan, terutama pengkaderan perempuan di kalangan NU.
Optimized Approach for Image Design Processing in Optical Networks: A Comparative Study
Authors: Hu Yunjie , Yang Fan 
Published: October 2023

Abstract
Deep space detection and remote sensing both require optical imaging devices. The optical imaging system often needs a bigger aperture mirror to attain high spatial resolution. As a result, several novel optical imaging systems, such as big segmented mirror telescopes, large aperture membrane diffractive optical telescopes, and others, have been researched in recent years. Real-time wavefront measurement is not required for the wavefront sensorless (WFSless) applied optics (AO) approach. The wavefront corrector is directly regulated via feedback following an image quality measure of the far-field image to correct for wavefront aberration. Integrating artificial neural networks (ANN) and deep learning plays a vital role in developing WFSless AO systems. This paper evaluated various important aspects to provide an in-depth review of the state-of-the-art machine learning-based algorithms deployed in WFSless AO systems. Finally, the applications and prospects were outlined.

Purpose of the study: to show the significance of ultrasound diagnostics in assessing the dynamics of the spleen mass coefficient in children of various age against the background of a chronic form of EBV virus.Materials and methods. The study was performed on 146 children aged 3 to 18 years suffering from chronic EBV virus. Depending on age, the children were divided into 3 groups. Group 1 included 63 patients aged 3 to 7 years; Group 2 consisted of 28 children aged 8 to 11 years; Group 3 included 55 children aged 12 to 18 years. The clinical, laboratory and ultrasound examination was conducted including ultrasound of the spleen with the further determination of its mass coefficient (SMC).Results. In the acute period of EBV virus, children of all age groups revealed an increase in SMC, while the maximum increase was observed in children aged 3 to 7 years and amounted to 6,88. Against the background of a complete clinical and laboratory recovery in this age group, the SMC remained at the level of 4.66 and did not reach the average values of healthy children of the same age. The follow-up dynamics for 15–18 months demonstrated the normalization of the SMC to the average values of healthy patients in accordance with their age (in children aged 12 years and older).Findings. Children in the age group from 3 to 7 years old had the maximum value of the spleen mass coefficient, both in the acute period and after complete clinical and laboratory recovery. The use of ultrasound technique with the assessment of the spleen mass coefficient in the chronic course of EBV virus allows expanding and determining the children contingent for further dynamic monitoring for prevention of possible complications.

Published: October 2023

Annotation. Gastric varicose veins are one of the common causes of gastrointestinal bleeding in patients with portal hypertension. Bleeding of this localization has a greater percentage of death and difficulty in achieving hemostasis than bleeding from esophageal varices. This paper discusses the etiology and main aspects of the pathophysiology of portal hypertension, the mechanisms of bleeding, which play an important role in the prevention of complications prevention. The venous outflow from the stomach, variants of porto-systemic collateral anastomoses and types of varicose veins of the stomach itself are presented in sufficient detail. The advantages and disadvantages of diagnostic imaging in the assessment of gastric varicose veins and the possible prediction of the risk of bleeding are demonstrated.Aim: to analyze the data of foreign and domestic literature on varicose veins of the stomach, to identify criteria that determine the risks of bleeding according to the methods of diagnostic imaging.Results. Analysis of foreign and domestic literature showed that the problem of diagnosing gastric varicose veins is extremely relevant and requires special consideration of all its various aspects. There are many diagnostic methods with certain advantages and disadvantages. But, in our opinion, the possibilities of non-invasive methods, especially computed tomography, in the diagnosis of varicose veins of the stomach and the prognosis of bleeding from them are underestimated and require further study.
The possibilities of modern radiological modalities in aortic coarctation diagnosis and preoperative planning in infants and young age group children

Published: October 2023

Objective. Evaluation of diagnostic value of modern imaging modalities: trans-thoracic echocardiography (TTE), CT-angiography (CTA) and cardio-MRI in diagnosis and preoperative planning of aortic coarctation correction (CoA) in in infants and young age group children.Materials and methods. 101 pediatric patients (aged 0 to 5 years) with CoA underwent TTE, 98 of them underwent CT, 30 – cardio MRI. On TTE, CTA and cardio-MRI aorta morphometry was performed. The most common anomalies associated with CoA (ventricular septal defect (VSD), patent ductus arteriosus (PDA), aberrant right subclavian artery (ARSA), hypoplastic arch and brachiocephalic vessels anomalies) were assessed.Results. The overall diagnostic accuracy of TTE, CT and cardiac-MRI in diagnosis of CoA were 89.1%, 95.9%, 86.7% respectively. There was no significant difference in the accuracy in detecting CoA between TTE, CT and MRI (p > 0.05). The accuracy of TTE in determining the brachiocephalic vessels anomalies, ARSA and arch hypoplasia was 84%, 93% and 85.3%, respectively. The accuracy of CT in determining the brachiocephalic vessels anomalies, ARSA and arch hypoplasia was 100%, 100% and 98% and cardio-MRI: 97.1%, 98.4% and 96.8%, respectively.Conclusion. TTE is a widely available and safe method, it has a high diagnostic value in determining CoA. Due to limitations in visualization of all parts of the aortic arch and the detection of concomitant anomalies, TTE cannot be the final method in planning the CoA correction. CT and MRI of the heart, as a TTE, are effective methods in the diagnosis of CoA, however, in the assessment of extracardiac anomalies, they equally show a significantly more accurate result.Taking into account the difficulties in conducting MRI of the heart in children under one year and younger age group, the need for a longer stay in anesthesia, the lack of additional diagnostically significant information in comparison with CT of the heart, cardio-MRI is not the method of choice in the primary diagnosis and preoperative planning of correction of CoA in children under one year and younger age group requiring the use of an anesthetic aid for the duration of the scan. Cardio-MRI may be the method of choice in preoperative planning of CoA in small children with absolute contraindications to the radiocontrast agent.

Objectives: to compare the consistency of echocardiographic Vmr and FR obtained by PISA and volumetric methods with Vmr and FR obtained by MRI in patients with secondary MR with reduced LV EF.Materials and methods. The analysis included data from 433 patients with secondary mitral regurgitation with reduced LV EF (less than 35%). The patients were divided into 2 groups: Group 1 – 286 patients with an average age of 64 ± 10 years, in whom the calculation of Rvol and RF was carried out by the PISA method. Group 2 – 147 patients with an average age of 63 ± 11 years, in whom the calculation of Rvol and RF was carried out by the volumetric method.Results. A moderate correlation was found between the indicators obtained by MRI and echocardiography, regardless of the method used, volumetric method Rvol r = 0.54 p = 0.01 and RF r = 0.56, p = 0.01, PISA method Rvol, r = 0.36, p = 0.01 and RF, r = 0.3, p = 0.01. The agreement in MR severity categorical scores between PISA and MRI was 27% in the diagnosis of severe mitral regurgitation and 50% in the diagnosis of moderate MR. The consistency in categorical MR severity scores between volumetric and MRI was 46% in the diagnosis of severe mitral regurgitation and 65% in the diagnosis of moderate MR. In the Bland–Altman analysis, the average difference in Rvol between PISA and MRI was 7.6 ± 13 ml with coincidence limits (30; –25 ml), the average difference in Rvol between volumetric and MRI was –2.5 ± 7.3 ml with coincidence limits (–12; 17 ml).Conclusions. MRI and echocardiography regardless of the method used have only a moderate correlation in the assessment of Rvol and RF in patients with secondary MR with reduced EF. The volumetric method may be the method of choice when calculating quantitative indicators of MR severity, as it has better agreement with MRI data compared to the PISA method.
