It is shown that when using a two-layer photoresist-Teflon dielectric, the latter has a high affinity for the dye used (the dye in a water environment wets the teflon surface), which allows it to be localized in a given location and thereby form display cells. Applying an external voltage changes the wetting condition, causing the dye to become hydrophobic to Teflon and thereby changing the light transmittance of the cell. Targeted supply of voltage to each cell will allow the formation of an image based on them.

Montaje de redes: cooperación cinematográfica, circulación trasnacional y acopio de materiales fílmicos sobre la Unidad Popular (1970-1973)
Authors: Campos Pérez Marcy
Published: October 2023

Objetivo/Contexto: Este artículo identifica las prácticas y espacios político-culturales que beneficiaron la difusión cinematográfica internacional asociada a la Unidad Popular (UP), que estuvieron determinadas tanto por la diplomacia impulsada desde el gobierno de Salvador Allende, como por dinámicas transnacionales en el marco general de la Guerra Fría. El objetivo es reconstruir de manera conectada estas instancias de cooperación e intercambio audiovisual entre Europa y América Latina, observando cómo estas imágenes se adaptaron a los imaginarios, expectativas y realidades de cada contexto de origen. Metodología: Por cuanto se trata de un estudio en perspectiva transnacional, el artículo se estructura a partir de un cruce de fuentes escritas y visuales, provenientes de distintas latitudes (especialmente Chile, Cuba, Francia y Alemania), y de distintos tipos de fondos de archivo (diplomáticos, cinematográficos y prensa periódica). Originalidad: El artículo busca resituar el estudio acerca del cine sobre la Unidad Popular en un doble sentido: primero, desplazar la perspectiva nacional hacia un enfoque que reconoce dinámicas y conexiones a distintas escalas, y luego, conectar en este periodo el estudio del audiovisual con prácticas como la diplomacia cultural. Conclusiones: Las redes de cooperación, difusión e intercambio cinematográfico durante el gobierno de la UP fueron posibles gracias a iniciativas nacionales e internacionales. Estas últimas que beneficiaron el acopio progresivo de materiales fílmicos en instituciones fuera de Chile y su papel fue fundamental en las campañas de solidaridad y en la difusión de imágenes vivas sobre Chile, después del Golpe en 1973.

Published: October 2023

The landscape of extrachromosomal circular DNA (eccDNA) during mammalian spermatogenesis, as well as the biogenesis mechanism remains to be explored. Here, we revealed widespread eccDNA formation in human sperms and mouse spermatogenesis. We noted that germline eccDNAs are derived from oligonucleosomal DNA fragmentation in cells likely undergoing cell death, providing a potential new way for quality assessment of human sperms. Interestingly, small-sized eccDNAs are associated with euchromatin, while large-sized ones are preferentially generated from heterochromatin. By comparing sperm eccDNAs with meiotic recombination hotspots and structural variations, we found that they are barely associated with
de novo
germline deletions. We further developed a bioinformatics pipeline to achieve nucleotide-resolution eccDNA detection even with the presence of microhomologous sequences that interfere with precise break-point identification. Empowered by our method, we provided strong evidence to show that microhomology-mediated end joining is the major eccDNA biogenesis mechanism. Together, our results shed lights on eccDNA biogenesis mechanism in mammalian germline cells.

Published: October 2023

Filamentous cyanobacteria are one of the oldest and today still most abundant lifeforms on earth, with manifold implications in ecology and economics. Their flexible filaments, often several hundred cells long, exhibit gliding motility in contact with solid surfaces. The underlying force generating mechanism is not yet understood. Here, we demonstrate that propulsion forces and friction coefficients are strongly coupled in the gliding motility of filamentous cyanobacteria. We directly measure their bending moduli using micropipette force sensors, and quantify propulsion and friction forces by analyzing their self-buckling behavior, complemented with analytical theory and simulations. The results indicate that slime extrusion unlikely generates the gliding forces, but support adhesion-based hypotheses, similar to the better-studied single-celled myxobacteria. The critical self-buckling lengths align well with the peaks of natural length distributions, indicating the importance of self-buckling for the organization of their collective in natural and artificial settings.
Nexus between sustainability and financial performance in the Serbian banking sector
Authors: Stakić Nikola , Barjaktarović Lidija
Published: October 2023

Research Question: The paper investigates various ESG (Environmental, Social and Governance) related practices within the leading European banking groups (BGs) present in Serbian banking sector (SBS), including their financial performances. Motivation: The goal of the research was to explore approach habits to sustainable business between the leading European BGs present in the SBS. It should have in mind that SBS are in compliance with their headquarter/major shareholder. The rising global worry about ESG issues and its overall impact forces banking business model to use holistic approach, including the plug-in of sustainability and responsible behaviours. The paper draws on sustainable banking surveys of Aracil et al. (2021) and Stefanovic et al. (2021) in Business-Case domain, applying them on SBS with introduction of 3 comparable sustainable indicators (environmental loans, reduction of tCO2, community investments). It is the first study which takes in respect ESG elements of principal BGs in SBS, with the comprehensive analysis of subject’s legislative framework. Idea: The core idea of the paper was to empirically investigate the sustainable practice in SBS, based on different banks’ reports and publications, including disclosed ESG indicators. E-loans (EL) and profitability indicators were examined individually as dependent variables since other ESG and financial (solvency, financial stability and efficiency) variables served as independent ones.   Data: Analysis was conducted using data of 4 European active BGs on SBS, in the period of 2015-2021, due to fact that there was the lack of quantitative metrics and non-uniform reporting practice. Tools: Statistical analysis (descriptive statistics, correlation, regression test utilizing ANOVA), were used to draw conclusions about the relationship variables, particularly correlation between ESG variables and profitability ratios. Findings: The study showed for analyzed BGs that: (1) they had unique ESG practice, based on global standards and EBA (European Banking Authority) regulation; (2) they had good credit risk management including E-risks in practice; (3) sustainability had significant inter-connectedness among ESG constituents, as well as with some of the financial metrics; (4) statistical significance of ESG metrics for EL; however similar findings are missing when it comes to association between financial performance (in terms of profitability) and ESG practice. Contribution: The paper introduces and expands existing research related to sustainable banking on SBS for further education of all stakeholders.

Authors: Shi Lin , DuJiang Minne , Gao Ping
Published: October 2023

Various forms of materials, such as pictures, videos and texts, have rapidly brought the college English translation teaching model into the era of multimedia integration. This makes it difficult for English teachers to improve college English translation by using unique materials, so as to form their own unique teaching style. In view of this, a multimedia comprehensive English translation framework based on the combination of big data technology and multimedia teaching mode is proposed. At the same time, the idea of building the framework is introduced from two perspectives: the integration of big data technology and multimedia, and the integration of multimedia and English teaching process. Then, a recursive neural network algorithm based on ant colony optimization algorithm is proposed and tested. Finally, the simulation results show that the proposed method has significantly improved the accuracy and retention rate, indicating the effectiveness of the framework.

Contenidos implícitos y comunicación lingüística: los constituyentes inarticulados en la interfaz léxico-gramática-pragmática
Authors:   , Dominiccini Bustos Eduardo
Published: October 2023

Esta tesis presenta una aproximación de interfaz entre el léxico, la gramática y la pragmática como fundamento para el estudio de fenómenos de infradeterminación lingüística. En particular, el análisis se centra en dos tipos de expresiones que se caracterizan por su falta de determinación: los complementos u objetos inexpresados y los fragmentos suboracionales. Estas expresiones se han discutido en la bibliografía especializada alrededor de la noción de “constituyentes inarticulados”, elementos implícitos ausentes de cualquier nivel de representación lingüística, pero necesarios para la interpretación adecuada de las proposiciones comunicadas por enunciados en situaciones concretas. Las condiciones de aparición e interpretación de estos elementos han sido uno de los temas centrales de discusión en la lingüística y la filosofía de las últimas dos décadas. El debate gira en torno a la posibilidad de establecer el grado de contribución contextual en la determinación de la forma y el significado, al tiempo que definir mejor (o desdibujar por completo) los límites entre lo lingüístico y lo extralingüístico. En este sentido, la presente investigación tiene un objetivo doble: establece criterios definidos para identificar constituyentes inarticulados, al tiempo que permite explicar la manera en la que tiene lugar su interpretación. La contribución de esta tesis a la lingüística teórica también es doble: por un lado, constituye una integración inédita de herramientas teóricas de tres enfoques distintos, a saber, el Lexicón Generativo, la Sintaxis Dinámica y la pragmática neogriceana; y por otra parte, proporciona un modelo de análisis formal de las relaciones entre la organización del léxico, la estructuración composicional y el procesamiento de inferencias. Esta perspectiva de interfaz se fundamenta en dos factores que consideramos determinantes para la relación entre sus componentes: a) la subespecificación, vista como propiedad inherente del sistema y manifestación concreta de un principio general de economía lingüística; b) la actualización incremental de la información, que permite la construcción progresiva de la interpretación. Planteado en estos términos, el enfoque de interfaz propuesto ofrece una alternativa novedosa con respecto al tratamiento dinámico de muchos fenómenos que se ubican en el límite entre la gramática y la pragmática de las lenguas naturales.

İnsan varoluşu gereği sosyal bir varlık olması yönüyle değer üreten bir varlıktır. Bu varlık ürettiği değerler aracılığıyla kendi için bir benlik inşa eder. Benlik, bir yandan bireyi diğerlerinden farklı kılarken diğer yandan da diğeriyle
arasında bir bağ kurmasını sağlar. Benlik tarihsel süreç içerisinde farklı bilimlerin ve disiplinlerin araştırma konusu haline gelmiştir. Tasavvuf edebiyatında da benlik kavramı birçok eserde yer almıştır. Erzumlu İbrahim Hakkı
da Dîvân adlı eserinde benlik kavramını kullanan tasavvuf edebiyatçıları arasında yer almaktadır. Bu araştırmada Dîvân adlı eserde yer alan benlik kavramı ele alındı. Benlik kavramının ne anlama geldiğini tespit edebilmek amacıyla
ilk öncelikle beyitlerde geçen benlik kavramı tarandı ve benlikle ilişkili diğer kavramlar belirlendi. Benlik kavramıyla ilişkili olduğu belirlenen kavramlar MAXQDA programında ayrı ayrı birer kod olarak tanımlandı. Kodların anlamlarından
hareketle manevi benlik, sosyal benlik ve nefsî benlik olmak üç farklı tema oluşturuldu. Kodlar ve temalar arasındaki ilişki analiz edilerek benliğin ne anlama geldiği ve ne tür bir benlik modeli oluştuğu ortaya çıkarılmaya çalışıldı.
Araştırmaya göre benlik nefsi, sosyal ve manevi olmak üzere üç farklı boyuttan oluşmakta ve nefsi benlik bireyin idsel yönünü, sosyal benlik bireyin diğerleriyle olan ilişki yönünü, manevi benlik de bireyin kutsal olanla ilişkisini
karşılık gelmektedir. Manevi ve sosyal benlik ilişkisel benlikle, nefsi benlik ise ayrıklaşmış benlikle açıklanabilir. Bu çalışma Türk İslam düşüncesine ait bir benlik modelini ortaya koyabilmesi açısından bilimsel bir öneme sahip
olduğu söylenebilir.

Authors: Sharma Gauri , Shukla Deepankar , Bhola Nitin
Published: October 2023

Introduction: Scar formation is an unavoidable sequelae of any surgical procedure. The goal is to produce fine scars with the least complications. Literature mentions various surgical factors that may lead to better quality of scars, one of which is the type of suture material used. Few studies exist in the literature that have compared the quality of scars after placement of polyglactin and polyamide sutures. Additionally, no studies have been done to compare the quality of scars following reconstruction with nasolabial flaps in patients with oral submucous fibrosis. Need for the study: This study will help evaluate and establish the healing outcomes in nasolabial flaps in the form of scars after placing subcutaneous 4-0 polyglactin (VICRYL™ ETHICON) and 4-0 polyamide (ETILONTM ETHICON) sutures. This will eventually lead to minimal tissue reaction and more aesthetic scars with fewer complications. Aim: To evaluate and compare the quality of scars postreconstruction with nasolabial flaps with subcutaneous polyglactin sutures and subcutaneous polyamide sutures. Materials and Methods: This is a prospective randomised triple-blinded trial which will be conducted in the Department of Oral and Maxillofacial Surgery, Sharad Pawar Dental College and Hospital (SPDCH), Sawangi (Meghe), Wardha, India. The trial will take place from July 2023 to June 2024. A total of 15 subjects with grade C Oral and Submucous Fibrosis (OSMF), who will undergo fibrotomy followed by reconstruction of bilateral nasolabial flaps, will be enrolled in the trial. Suturing of one side of the flap will be done using 4-0 polyglactin (VICRYL™ ETHICON) suture subcutaneously, and the other side will use 4-0 polyamide (Ethilon™ ETHICON) suture subcutaneously. The scar tissues will be periodically evaluated at one week, one month, and three months postoperative period to assess the healing outcomes and overall aesthetic appearance using the Patient and Observer Scar Assessment Scale (POSAS) using Chi-square test and Student’s t-test.

Authors: Mehrotra Bandana , Kapoor Ashok Kumar , Srivastava Rajesh Kumar , Shyam Hari , Mehrotra Supriya
Published: October 2023

Smoldering Multiple Myeloma (SMM) is defined as focal premalignant plasma cell proliferation in the bone marrow, along with the presence of monoclonal or biclonal protein bands in the patient’s serum. The current patient complained of severe weakness six months after knee arthroplasty. The patient exhibited a monoclonal (M-1) band on Serum Protein Electrophoresis (SPEP), which was observed in the γ-globulin region in combination with γ-heavy chains. Another protein band (M-2) was identified in the β-globulin region. These paraproteins were later confirmed by Immunofixation Electrophoresis (IFE), and both proteins reacted with anti-λ antibody. The concentration of the M-1 band was 32% (2.82 gm/dL), while the concentration of the M-2 protein band was 7.9% (0.7 gm/dL). Additionally, the total serum proteins measured 8.84 gm/dL. The plasma cell count in the Bone Marrow (BMPC) was approximately 20%. Provisionally, the patient was diagnosed as a case of gammopathy, with non-IgM Monoclonal Gammopathy of Undetermined Significance (MGUS), light chain MGUS, SMM, and MM considered in the differential diagnosis. However, the final diagnosis for the current patient was SMM. The patient responded well to treatment with cyclophosphamide and prednisone.

Authors: Chatterjee Suman , Chakrabarti Phalguni , Lokanathan V
Published: October 2023

Introduction: Hypothyroidism, one of the most common thyroid gland disorders, can cause electrolyte disturbances in the body. Hypothyroidism can alter mineral metabolism by changing the levels of serum calcium and magnesium. Therefore, it is essential to study any abnormalities in calcium and magnesium metabolism in patients with hypothyroidism. Aim: The aim of this study was to assess the levels of calcium and magnesium in patients with hypothyroidism and to study the correlation between Thyroid Stimulating Hormone (TSH), fT3, and fT4 with calcium and magnesium in subclinical and Overt Hypothyroidism (OH). Materials and Methods: This cross-sectional study was held from August 2019 to January 2020 in the Department of Biochemistry, BS Medical College, Bankura. A total of 150 subjects were included in the study, distributed equally among three groups: euthyroidism, subclinical hypothyroidism, and OH. Serum TSH, fT3, fT4, calcium, and magnesium levels were determined in the laboratory, and the data obtained were statistically analysed using ANOVA test and Pearson’s correlation test. Results: Out of a total of 150 subjects, 61 were female, among whom 23 had subclinical hypothyroidism and 21 had OH. There were significant differences in the mean levels of TSH, fT3, fT4, calcium, and magnesium between the SCH, OH, and euthyroid groups. The study showed that the mean serum calcium level was significantly lower in SCH and OH compared to euthyroids, while the level of serum magnesium was significantly increased in SCH and OH compared to euthyroid. There was a statistically significant negative correlation between TSH and serum calcium in both OH and SCH, while a statistically significant positive correlation was observed between TSH and serum magnesium levels in both groups. Conclusion: The present study revealed that serum magnesium levels were high while serum calcium levels were low in both subclinical hypothyroidism and OH when compared to euthyroid subjects. Additionally, calcium levels negatively correlated with TSH, while magnesium levels positively correlated with TSH levels.
Treatment Dilemma in an Unusual Case of Dengue Fever with Cardiomyopathy and Nephropathy: A Case Report
Authors: Maitra Somnath , Seal Ratul , Ray Koushik
Published: October 2023

Dengue is a viral illness in humans caused by the bite of infected Aedes mosquitoes, mostly Aedes aegypti and also Aedes albopictus. There are four serotypes of the Dengue virus that cause infection in humans and may lead to a variety of complications. Myocarditis and cardiomyopathy can occur in several viral and non viral infections, increasing morbidity and mortality. Nephropathy may also arise in dengue fever, causing complications. The case presented here involved both complications, nephropathy and cardiomyopathy, posing treatment challenges in terms of altering fluid and electrolyte status, which hindered fluid therapy as fluid overload would be detrimental. However, the complications were reversible with the normalisation of echocardiography and urea and creatinine levels. Long-term follow-up is necessary to monitor cardiac and renal function, as some patients may progress to Chronic Kidney Disease (CKD). The patient presented with fever, headache, vomiting, and haematuria, along with signs of fluid overload. There was a past history of fever, and since both Immunoglobulin G (IgG) and IgM Dengue antibodies were positive, this may be a case of a second episode of dengue fever causing complications. This case report emphasises the diagnostic and treatment challenges in a dengue patient with cardiomyopathy and nephropathy, where excessive fluid replacement may increase morbidity and mortality. Additionally, long-term follow-up of these patients is necessary.

Introduction: Endophthalmitis is a serious, sight-threatening purulent inflammation of the intraocular cavities of the eyeball. It greatly affects vision and can lead to severe complications such as panophthalmitis. The prevalence of endophthalmitis varies from one place to another. Aim: To identify the various aetiological and predisposing factors that contribute to endophthalmitis and to assess the visual outcomes following medical intervention (intravitreal antibiotics only) and surgical intervention (both intravitreal antibiotics and pars plana vitrectomy). Materials and Methods: The present study was conducted in the Department of Ophthalmology at Trichy SRM Medical College Hospital and Research Centre, Trichy, Tamil Nadu, India between January 2023 and February 2023. Demographic and clinical data of patients diagnosed with endophthalmitis over a two year period from October 2020 to September 2022 were collected from the Medical Records Department of the Institution for analysis. A total of 50 case records were selected using convenience sampling. Demographic details such as age, gender, predisposing risk factors, visual acuity, microbiological profiles, treatment modalities, and final visual acuity were collected from the present study. Quantitative data was presented as Mean and Standard Deviation (SD), while qualitative data was presented as frequencies and percentages. Summary statistics were analysed using Microsoft Excel version 2018. Results: In present study, 29 (58%) were males and 21 (42%) were females, with the majority falling within the age group of 50-70 years. The mean age of the sample was 53.8±16.1 years. Postoperative causes accounted for 39 (78%) of the cases, with phacoemulsification surgery with foldable intraocular lens implantation being the leading cause in 23 (58.7%) cases. Culture positivity was observed in only 22 (44%) cases, with Staphylococcus (Staph) epidermidis as the major causative organism. The best visual acuity achieved was 6/12 for two patients. Conclusion: Postoperative endophthalmitis remains the most common cause of endophthalmitis. Additionally, patients who presented with better visual acuity had a better visual outcome after treatment. Therefore, patients should be educated about the early signs of endophthalmitis to ensure prompt medical attention and improve visual recovery

Authors: Deekshith K , Alagingi Nityal Kumar
Published: October 2023

Introduction: The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a valid and reliable tool for assessing knee injury and osteoarthritis (OA). It has been cross-culturally adapted into several Indian languages. However, the reliability of the Kannada translation of the KOOS scale has not been established. Aim: The aim of this study was to confirm the reliability of the Kannada translation of the KOOS scale and to assess the interrater and test-retest reliability of the culturally adapted KOOS outcome measure. Materials and Methods: A cross-sectional study was conducted involving 74 patients diagnosed with OA. All patients were asked to complete the KOOS questionnaire. To test interrater reliability, two raters completed the questionnaire, while for test-retest reliability, one rater was involved. The procedure was repeated after a week. The scores of both questionnaires were then compared to check the inter-rater and test-retest reliability of the cross-culturally adapted KOOS outcome measure. Cronbach’s Alpha and the Intraclass Correlation Coefficient (ICC) were utilised to determine the scale’s reliability. Results: The entire scale demonstrated high reliability, with an ICC ranging from 0.96 to 0.98 for all subscales. The domainwise and overall Cronbach’s Alpha values were >0.70. There was agreement between the raters (p<0.01) and test-retest data (p<0.01) for pain and activities of daily living items. Highly significant correlations were also observed between test-retest data for all items related to sport and recreation function and knee-related quality of life (p<0.001). Conclusion: The Cronbach’s Alpha values obtained for all domains of the scale were >0.70, indicating the scale’s reliability. Additionally, the scale demonstrated consistency as the ICC was determined to be substantial.

The demand for diesel fuel in the transport industry is expected to rise due to greenhouse gas laws and global economic expansion, necessitating the search for alternative sources. If light distillate fuels can match diesel fuel's efficiency and cleanliness at a more affordable cost, they could potentially enter the market. This study assessed a 1-cylinder, 4-stroke diesel engine's performance using various blends of diesel and heavy naphtha: D100, D97.5N2.5, D95N5, D92.5N7.5, and D90N10. Tests were conducted at 3000 rpm and variable loads, revealing that the maximum permissible naphtha content in D100 is 10%. Higher naphtha proportions led to misfire and instability under heavy loads. 100% diesel demonstrated the lowest brake-specific fuel consumption and higher thermal efficiency, while 90% diesel + 10% naphtha showed the highest fuel consumption and lower thermal efficiency.

Published: October 2023

Summary: Rasmussen's encephalitis (RE) is a rare and severe chronic inflammatory brain disease resulting in drug-resistant epilepsy and progressive hemispheric destruction with neurological deficit. ER is associated with deterioration of background EEG activity, progressive atrophy of the affected hemisphere on MRI and extensive PET hypometabolism over the affected hemisphere. We report the case of a 6-year-old girl who presented with pharmacoresistant epilepsy.

Observation: A 6-year-old child with no particular medical history presented 6 months prior to admission with epilepsy resistant to all therapeutic classes (antiepileptic drugs). Clinical examination revealed left hemiparesis with facial involvement and constant left hemi-myoclonus.

An EEG showed a pattern compatible with a continuous epileptic encephalopathy that could correlate with Rasmussen syndrome.

Cerebral MRI Revealed: right cerebral hemiatrophy with secondary homolateral hippocampal sclero-atrophy, compatible with Rasmussen encephalitis.

The patient received immunoglobulins and a corticosteroid bolus, but without improvement; she was therefore a candidate for surgical treatment.

Rasmussen's encephalopathy is a rare and serious disease that can be responsible for paresis and cognitive decline. Its pathophysiology is still poorly defined, and it mainly affects children.

Nigeria experienced significant depreciation of her currency during the specified period of this study, mainly due to factors such as falling oil prices, external economic conditions such as slowdown in global economic growth, trade tensions which led to capital outflows from emerging markets including markets in Nigeria, tightening of global monetary policy which affected capital flows to these  emerging markets, coupled with domestic macroeconomic challenges like concerns over policy consistency, governance issues and security challenges,  capital flight and weakened investors’’ confidence. These conditions collectively created an adverse environment for the Nigerian economy, leading to the depreciation of Naira. Consequently, this study set out to achieve the main objective of investigating on a more recent basis, effects of exchange rate on domestic price level in Nigeria. The period covered was from January 2015 through December 2022. The study adopted the Autoregressive Distributed Lag (ARDL) model and the variables included consumer price inflation, nominal exchange rate, import prices, international crude oil prices and real output growth. We found insignificant positive impact of the nominal exchange rate on consumer price inflation in Nigeria. The import prices also proved a significant effect on consumer price inflation in Nigeria. the study recommends that Governments at all levels in the country should encourage and support the innovative ideas of business firms and individuals. This will support local production, hence, there can be substitution of imported goods for domestically produced goods and the exchange rate will be stable.
