Comparing Apple to Amazon: Just a Matter of Words in the Machine Learning World
Authors: Shivaani MV
Published: April 2021

Comparative analysis commands special attention in financial analysis as it not only facilitates understanding of year-on-year changes but also of trends in the performance and position of a company. It is often a go-to tool for competitor analysis. In this note, I illustrate the use of R (software), its allied packages, and textual analysis algorithms to extend the use of comparative analysis to “unstructured” information presented in the MD&A section of annual reports. For this use case, I consider two giant tech rivals, Apple Inc. and Amazon.com Inc., and present a comparative analysis of their MD&A section using Cosine and Jaccard similarity measures. I also compare the most important words based on tf-idf and sentiments for each company and across the two companies. When supplemented with financial information, comparative analysis can offer novel insights for analysts, managers, researchers, and academics and is a valuable tool to include in accounting curricula.

OBJECTIVE

To determine whether interrupting sitting with brief bouts of simple resistance activities (SRAs) at different frequencies improves postprandial glucose, insulin, and triglycerides in adults with medication-controlled type 2 diabetes (T2D).

RESEARCH DESIGN AND METHODS

Participants (n = 23, 10 of whom were female, with mean ± SD age 62 ± 8 years and BMI 32.7 ± 3.5 kg · m−2) completed a three-armed randomized crossover trial (6- to 14-day washout): sitting uninterrupted for 7 h (SIT), sitting with 3-min SRAs (half squats, calf raises, gluteal contractions, and knee raises) every 30 min (SRA3), and sitting with 6-min SRAs every 60 min (SRA6). Net incremental areas under the curve (iAUCnet) for glucose, insulin, and triglycerides were compared between conditions.

RESULTS

Glucose and insulin 7-h iAUCnet were attenuated significantly during SRA6 (glucose 17.0 mmol · h · L−1, 95% CI 12.5, 21.4; insulin 1,229 pmol · h · L−1, 95% CI 982, 1,538) in comparison with SIT (glucose 21.4 mmol · h · L−1, 95% CI 16.9, 25.8; insulin 1,411 pmol · h · L−1, 95% CI 1,128, 1,767; P < 0.05) and in comparison with SRA3 (for glucose only) (22.1 mmol · h · L−1, 95% CI 17.7, 26.6; P = 0.01) No significant differences in glucose or insulin iAUCnet were observed in comparison of SRA3 and SIT. There was no statistically significant effect of condition on triglyceride iAUCnet.

CONCLUSIONS

In adults with medication-controlled T2D, interrupting prolonged sitting with 6-min SRAs every 60 min reduced postprandial glucose and insulin responses. Other frequencies of interruptions and potential longer-term benefits require examination to clarify clinical relevance.
Incremental Dental Expenditures Associated With Diabetes Among Noninstitutionalized U.S. Adults Aged ≥18 Years Old in 2016–2017
Authors: Chen Yu , Zhang Ping , Luman Elizabeth T. , Griffin Susan O. , Rolka Deborah B.
Published: April 2021

OBJECTIVE

Diabetes is associated with poor oral health, but incremental expenditures for dental care associated with diabetes in the U.S. are unknown. We aimed to quantify these incremental expenditures per person and for the nation.

RESEARCH DESIGN AND METHODS

We analyzed data from 46,633 noninstitutionalized adults aged ≥18 years old who participated in the 2016–2017 Medical Expenditure Panel Survey. We used two-part models to estimate dental expenditures per person in total, by payment source, and by dental service type, controlling for sociodemographic characteristics, health status, and geographic variables. Incremental expenditure was the difference in predicted expenditure for dental care between adults with and without diabetes. The total expenditure for the U.S. was the expenditure per person multiplied by the estimated number of people with diabetes. Expenditures were adjusted to 2017 USD.

RESULTS

The mean adjusted annual diabetes-associated incremental dental expenditure was $77 per person and $1.9 billion for the nation. Of this incremental expenditure, 51% ($40) and 39% ($30) were paid out of pocket and by private insurance, 69% ($53) of the incremental expenditure was for restorative/prosthetic/surgical services, and adults with diabetes had lower expenditure for preventive services than those without (incremental, −$7). Incremental expenditures were higher in older adults, non-Hispanic Whites, and people with higher levels of income and education.

CONCLUSIONS

Diabetes is associated with higher dental expenditures. These results fill a gap in the estimates of total medical expenditures associated with diabetes in the U.S. and highlight the importance of preventive dental care among people with diabetes.

Published: April 2021

El objetivo del presente estudio fue analizar la relación entre los niveles de actividad física y obesidad en escolares de primaria pertenecientes a una escuela pública estatal de la ciudad de Chihuahua, México. Se realizó un estudio descriptivo, correlacional y transversal, se seleccionó una muestra por conveniencia, 326 escolares de 9.1±2 años de edad (178 niñas y 148 niños). Los niveles de Actividad Física (AF) fueron estimados mediante una entrevista, utilizando el “The Godin-Shephard Leisure-Time Physical Activity Questionnaire” (GSGSLTPAQQ) y para identificar la obesidad se utilizó el Índice de Masa Corporal (IMC) y la Circunferencia de Cintura (CC). El análisis estadístico nos mostró correlaciones bilaterales de Pearson negativas con significancia entre la AF vigorosa y el IMC (r=-.139, p≤0.050), así como entre la CC (r=-.150, p≤0.010). Además los escolares con obesidad mostraron que realizan significativamente menos AF vigorosa por semana, al compararlos vs los que presentan sobrepeso (p≤0.050), y los que presentan normo peso (p≤0.010). Los resultados nos indican que la mayoría de los escolares que presentan mayor IMC y CC realizan menos AF vigorosa de forma significativa. De igual forma podemos establecer, que los escolares con obesidad realizan menos AF vigorosa por semana de forma significativa. Por lo que es necesario que se promuevan actividades físicas vigorosas dentro y fuera de la escuela en este tipo de poblaciones, con el fin de prevenir la obesidad.
Something like a Phenomenon
Authors: Peikes Tyler
Published: April 2021

Phenomenology is a twentieth century school of thought that addresses philosophical questions by focusing our attention on the nature of experience. Emmanuel Lévinas combines this approach with the fundamentally ethical knowledge that there is another who is beyond us, who is exterior. My project examines Lévinas’ ethically informed phenomenological reflections on the structure of two specific experiences, namely love and forgiveness. Forgiving and being forgiven are everyday, familiar experiences. But what are we really doing when we forgive someone? My approach is exegetical in spirit; while attempting to remain faithful to Lévinas’ esoteric texts, I resort to combining Levinasian sources in order to survey and restate his ideas and to fill in some of the blanks that confront the reader. I extrapolate in good faith as a student of Lévinas, guided by shared intuitions and insights. I begin by exploring our intuitions about what may be considered a wrong that nonetheless can be forgiven. Then, I explore two paradoxes of forgiveness to illustrate the complexity of the process and indicate the path towards a solution. Before I arrive at this solution, I compare the experience of forgiveness to the experience of love and discover that what lies at the heart of the issue is the intentional altering of memory and history. This phenomenon turns out to be not only possible but commonplace in everyday experience. Through it the meaning of felix culpa, the happiness of guilt, can be revealed. This revelation will be the happy ending of my presentation.
Elevated Love: Correggio and Michelangelo’s Depictions of The Rape of Ganymede
Authors: Li Yvonne
Published: April 2021

Chronicling the lives of the pagan Gods, Metamorphoses was essentially a compilation of stories based on Greek mythology. As the title suggests, the primary theme throughout the work was that of change and evolution. Suggesting that the process was naturally occurring, the stories also sent the message that in spite of any physical transformation, the soul or spirit would remain fundamentally the same. In short, the world was in constant flux but the soul was not. Although this idea ran throughout the epic poem, Ovid’s story was richly layered and comprised of many other aspects, with various themes continuing throughout the book. One reoccurring theme was that of unrequited love, which often involved one character in aggressive pursuit. Jove, otherwise known as Jupiter in Roman mythology, was the supreme God of the Heavens and though he was married to Juno, he often lusted after the most beautiful of mortals in the earthly realm. This presentation proposes that while Ovid’s Metamorphoses provided a starting point for artists, these Ovidian stories were open to interpretation (and reinterpretation). Similar to religious imagery, which was most dominant at the time, they were constantly adapted in art. Examining two different portrayals of the Rape of Ganymede, one by Correggio and the other by Michelangelo demonstrates how Metamorphoses, as the title implies, was able to continually evolve and remain relevant to the changing social values.
13. The Bioaccumulation of Elements through the Food Web in Lake Albert, Uganda
Authors: Cox Lyndsey
Published: April 2021

The importance of heavy metal assessments in African lakes is increasing due to human population growth and industrialization. Trace metal concentrations in freshwater fish from Sub-Saharan lakes have largely been found to be below the World Health Organizations permissible levels for human consumption. Lake Albert, Uganda, has seen substantial increases in human population and industry over the last 50 years, yet little is known about the bioaccumulation of potentially harmful elements through the food web. Recent work using stable nitrogen ( 15N) isotopes found mercury in Lake Albert fish to be biomagnifying to concentrations among the highest in Africa. Some fish exceeded 1000 ng/g ww, while the World Health Organizations recommended limit for mercury consumption is 200 ng/g ww. This study supplements the previous Lake Albert mercury work by examining Al, As, Cd, Cs, Co, Cr, Cu, Mg, Ni, Mn, Fe, Rb and Zn concentrations in various Lake Albert fish species using Inductively Coupled Mass Spectrometry. Biomagnification will be assessed by combining the metal analysis findings with fish trophic levels (estimated using 15N). The results of this study increase understanding of the bioaccumulation trends of many metals that have not yet been extensively studied in freshwater fish. Such information is critical to the development of effective aquatic management strategies and consumption guidelines for the Lake Albert area.
The Changing Nature of Academic Work: Canadian Universities and the Flexible Firm Model
Authors: Krushell Josh
Published: April 2021

Though much literature has been produced on the topic of academic restructuring, those works concerned  with the Canadian context have mainly focused on issues of corporate­university linkages, the role of state coordination of public universities, and the disparity between funding and student enrollment. Very little work has been done in documenting or analysing the role of adjunct faculty, who now make up nearly half  the university faculty, in Canadian universities. Statistics Canada has only once collected data on part­time faculty, and only one current analysis of this data has been conducted (Omiecinski, 2003). The Canadian  Association of University Teachers, furthermore, only publishes data concerning full­time faculty  members. The implications of an emerging division between the use of full­time and part­time faculty on  the nature of academic work and the quality of post­secondary education has been yet unexamined. Drawing on labour market segmentation theory, this study presents the multiple ways in which the work of  academic staff in Canadian post­secondary education has conformed to the principles of the flexible firm model, first observed of private business firms in the 1980s by John Atkinson. A series of semi­structured  interviews with academic faculty and administrators, as well as a collection of current secondary source data, informed the basis of this research. It was found that the changing nature of academic work in post­  secondary education is negatively affecting the quality of undergraduate education provided in Canada.
Flow Experience and Life Satisfaction
Authors: King Jared
Published: April 2021

The present study aims to examine the relationship between experiencing flow in academic work and life satisfaction. The flow experience has been defined as a state of absolute absorption in an activity, often  resulting in feelings of satisfaction (Csikszentmihalyi, 1975, 1990). However, it is unknown whether the satisfaction resulting from flow contributes to an enduring sense of satisfaction, or whether flow can be used as a tool to sustain increased levels of satisfaction over time. Thus, the goals of the present experiment are threefold: 1) to test the relationship between experiencing flow and life satisfaction, 2) to  determine whether experiencing flow has a lasting effect on life satisfaction, and 3) to evaluate the utility of  flow as an intervention strategy for increasing and sustaining levels of life satisfaction. Results are forthcoming

Published: April 2021

Introducción: El traumatismo craneoencefálico (TCE) es la tercera causa de muerte violenta; puede estar relacionado con la ingesta de alcohol, la edad, el sexo y la estación del año; el objetivo de este estudio fue determinar la relación estadística entre la intoxicación etílica y los traumatismos craneoencefálicos en las autopsias realizadas en el Servicio Médico Forense del municipio de Veracruz-Boca del Río.Material y Métodos: Se realizó un estudio retrospectivo, analítico y transversal, en 1306 expedientes del SEMEFO Veracruz de los cuales 302 fueron correspondieron a defunciones con traumatismos craneoencefálicos ocurridos entre los periodos de enero 2016 a diciembre 2017. Se utilizó estadística inferencial por medio de la prueba X2, el riesgo de cada factor razón de momios e intervalo de confianza del 95%.Resultados: La población se dividió en dos grupos: el grupo I estuvo formado por individuos con diagnóstico de TCE e intoxicación etílica (n=118, 52%) y el grupo II estuvo formado por individuos con diagnóstico de TCE sin intoxicación etílica (n=110, 48%) (RM = 3.59 IC 95% 1.36-6.45); esta variable fue estadísticamente significativa (X2 = 3.286, p<0.05). Se registraron 142 defunciones por TCE en 2016 y 160 defunciones por TCE en 2017.Conclusiones: Como causa de defunción, el TCE se asoció a intoxicación etílica en un 52% de los casos, con mayor frecuencia en el sexo masculino y en el mes de diciembre; las edades más afectadas fueron de 15 a los 46 años.Palabras clave: Traumatismos craneoencefálicos (TCE), alcoholismo, defunción
La realidad silenciosa de la violencia contra el hombre, ¿es también violencia de género?
Authors: Araujo Cuauro Juan Carlos
Published: April 2021

El propósito de este artículo es caracterizar si la violencia contra el hombre es también considerada violencia de género, así como analizar su tratamiento en el derecho positivo venezolano. Descripción: En el 88% de los casos se abstienen de denunciar por vergüenza y porque existe un vacío legal pues la ley sólo cataloga un delito como violencia doméstica cuando el hombre maltrata a la mujer; asimismo el 70% manifestó la no existencia de instituciones exclusiva para los hombres en materia de violencia de género; por otra parte el 90% manifestó la falta de apoyo jurídico, ya que las leyes venezolanas no tipifican la violencia doméstica hacia el hombre, en materia de protección a hombres maltratados son prácticamente nula o escasas; por último el 95% de los casos el agresor fue mujer (exnovia, exesposa, excompañera o ex concubino, examante, novia, esposa). Enfoque: En el ordenamiento jurídico venezolano la violencia contra el hombre constituye un grave problema de violación sistemática de sus derechos, que se muestra en forma dramática debido a las concepciones jurídicas tradicionales, basadas en paradigmas positivistas y sexistas feministas. En Venezuela, cuando un hombre va a denunciar una agresión, la misma es procesada como una denuncia de delito común, solo uno de cada diez hombres que es agredido por alguna mujer lo denuncia ante el Ministerio Público. Conclusiones: En Venezuela, así como en muchos países de Latinoamérica, los sistemas judiciales atraviesan momentos de crisis y hacen frente a problemas graves de la falta de legislaciones sobre la violencia hacia el género masculino.

Algunas consideraciones sobre el aborto desde la perspectiva médico forense y social
Authors: Rodríguez Jorge Ricardo Romel , Pérez González Ernesto
Published: April 2021

La fecundación, el embarazo y el parto humano son un proceso fisiológico pero a la vez regulado por el hombre y la mujer, que en normal funcionamiento lo conciben de mutuo acuerdo; el producto de la concepción es unos de los motivos de mayor alegría y unión en la familia, pero lamentablemente esta dinámica con extrema frecuencia se encuentra sujeta a disímiles factores que pueden modificar y distorsionar su esencia; estos factores incluyen regulaciones jurídicas, sociales y religiosas, en las que los factores culturales y psicológicos constituyen un factor incluyente. El presente trabajo tiene como objetivo demostrar la necesidad de licitar el aborto desde las diferentes perspectivas del autor. Para ello se realizó una profunda revisión documental de la literatura científica y se incluyó la experiencia del autor en los casos trabajados durante sus 24 años de experiencia. Cada país en su legislación contempla la definición y posición ante el aborto. El desarrollo económico y social son elementos que con frecuencia pasan en forma desapercibida, pero regulan la natalidad y por otra parte incentivan la realización de abortos en embarazos no deseados utilizando medios legales e ilegales, según la nación.Palabras claves: concepción, embarazo, aborto, legislación.
Atravesar la dialéctica del capital. El encuentro de Marx con el método en estado práctico
Authors: Expósito Julia
Published: April 2021

Dialéctica y capitalismo revisten en el pensamiento de Marx un vínculo inquebrantable. La especificidad de la dialéctica marxista se expondría en la praxis como su base material pero también teórica, a través de la exposición de un problema práctico como lo es el capitalismo. Por tanto, la dialéctica no sería un método capaz de ser aplicado, sino que se descubriría justamente de las temporalidades mismas del capital y de sus resistencias. La meta es la exponer cómo las determinaciones del capitalismo -como la relación valor/trabajo- que Marx formula, presuponen a las categorías de la dialéctica –totalidad, contradicción, negatividad, objetividad– en el mismo devenir de las lógicas de capital para demostrar cómo el devenir de lo social lejos de responder a la lógica de un despliegue necesario estaría supeditado a la enigmática contingencia.
Takotsubo cardiomyopathy – a case report of a 62-year-old female with several severe comorbidities
Authors: Kosowski Wojciech , Kabaj Maciej , Bastek Magdalena , Mysiak Andrzej , Negrusz-Kawecka Marta
Published: April 2021

Kardiomiopatia takotsubo, zespół balotującego koniuszka, kardiomiopatia stresowa, zespół złamanego serca, to terminy określające tą samą jednostkę chorobową. Jest ona ostrym, odwracalnym stanem kardiologicznym charakteryzującym się objawami imitującymi ostry zespół wieńcowy (OZW). W większości przypadków kardiomiopatia takotsubo występuje na skutek stresotwórczego bodźca emocjonalnego lub fizycznego i dotyczy przede wszystkim starszych kobiet. Prezentujemy opis przypadku 62-letniej kobiety z historią nadciśnienia tętniczego stopnia 2, hipercholesterolemii, miastenii, nowotworu nerki prawej, zespołu paranowotworowego i osteoporozy, u której rozpoznano kardiomiopatię takotsubo. Przy przyjęciu do szpitala pacjenta zgłaszała duszność i ból w klatce piersiowej. W EKG stwierdzono ujemne załamki T w odprowadzeniach I, II, aVL, aVF, V2-V6. Badania laboratoryjne wykazały podwyższone stężenie troponin sercowych. Z powodu prezentowania przy przyjęciu objawów imitujących OZW, postępowanie diagnostyczne i terapeutyczne było pierwotnie prowadzone w kierunku OZW, dopóki nie został on wykluczony na podstawie rzetelnych danych. Szacuje się, że u 1 do 2% pacjentów, u których podejrzewa się OZW, ostatecznie stawia się rozpoznanie kardiomiopatii takotsubo. Rozróżnienie kardiomiopatii Takotsubo od OZW pociąga za sobą wiele implikacji, w tym tych dotyczących farmakoterapii.

Introduction The COVID-pandemic does not leave the dental practice unattended. The objective is to analyze why the COVID-19 pandemic urges changes in daily dental practice in the Belgian context. Methodology The Leuven University Hospital’s view is based on Belgian and Leuven University data and existing guidelines concerning hygiene measures in dental practices. The approach chosen is a narrative qualitative approach. Results Although no transmission of COVID-19 has been reported in Belgian dental practices, the number of health care workers infected and deceased urges for safety measures. Conclusions In the absence of a vaccine and of reliable data about the infectivity of droplet and droplet cores, dental procedures causing aerosol should be considered as possible sources of viral spread when treating contagious patients, symptomatic or asymptomatic.
Hemşirelerin Fiziksel Aktivite Düzeyleri ile Yaşam Kalitesi ve Tükenmişlik Düzeyleri Arasındaki İlişkinin İncelenmesi
Authors: AYDIN Yasemen , KAMUK Yetkin Utku
Published: April 2021

Bu çalışmanın amacı, hemşirelerin fiziksel aktivite düzeyleri ile yaşam kalitesi ve tükenmişlik düzeyleri arasındaki ilişkinin incelenmesidir. Çalışmaya, Hitit Üniversitesi Erol Olçok Eğitim ve Araştırma Hastanesi’nde görev yapan 212 hemşire katılmış ve katılımcıların tamamına Fiziksel Aktivite Ölçeği, SF-36 Yaşam Kalitesi Ölçeği ve Maslach Tükenmişlik Envanteri uygulanmıştır. Shapiro-Wilk testi sonuçlarına göre, verilerin normal dağılıma uygun olmadığı görüldüğünden (p<0,05), ikili gruplar karşılaştırmaları için Mann-Whitney U, çoklu grup karşılaştırmaları için Kruskal-Wallis H testleri kullanılmıştır. Değişkenler arasındaki ilişkiler ise Spearman sıra sayılar korelasyon katsayısı kullanılarak incelenmiştir. Anlamlılık düzeyi tüm testlerde p<0,05 olarak belirlenmiştir. İstatistiksel analizler sonucunda, erkek ve kadın hemşireler arasında yaşam kalitesinin alt boyutları olan fiziksel fonksiyon, emosyonel rol güçlüğü, enerji/canlılık/vitalite, sosyal işlevsellik, ağrı, genel sağlık algısı ve ruhsal sağlık alt boyutlarında erkekler lehine istatistiksel olarak anlamlı fark olduğu bulunmuştur. Tükenmişlik düzeyine ait alt boyutlardan kişisel başarı eksikliği puanlarına göre, kıdem süresi düşük olanların ve evlilerin kendilerini başarısız gördüklerini ortaya koymuştur. Obezite düzeyinin, fiziksel fonksiyon ve emosyonel rol güçlüğü alt boyutlarında bozucu etkiye sahip olduğu ortaya konmuştur. Görev yerine göre değerlendirildiğinde, yatan hasta servislerinde çalışanlar en düşük SF-36 puanlarına sahiptirler. Hemşirelerin fiziksel aktivite düzeyleri ile yalnızca yaşam kalitesi alt boyutu olan fiziksel fonksiyon alt boyutu arasında düşük düzeyde pozitif korelasyon olduğu, yaşam kalitesine ait diğer alt boyutlar ile fiziksel aktivite arasında anlamlı bir ilişkinin bulunmadığı görülmüştür. Ayrıca fiziksel aktivite ile tükenmişlik düzeyleri arasında herhangi bir ilişki saptanmamıştır. Sonuç olarak, hemşirelerin yaşam kalitesi düzeylerinin düşük olduğu, tükenmişlik düzeylerinin yüksek ve fiziksel aktivite düzeylerinin yetersiz olduğu bulunmuştur.

We question the conclusions reported in the paper "Entropy-stabilized Oxides, by C. Rost et al., by looking into the role of configurational entropy as the stabilization of the rock-salt cubic structure of the Mg0.2Co0.2Ni0.2Cu0.2Zn0.2O (HEO) solid solution (SS). First, we demonstrate that configurational entropy can be reduced from 1.61R for HEO to 0.5R for a two-member SS, still obtaining a single-phase material if the molar fractions of ZnO and CuO are 0.2. These SSs behave identically as HEO regarding the reversible transformation between a multi- and single-phase states when temperatures are cycled between 800 and 1000 °C. Second, we demonstrate that the different SSs presenting a configurational entropy significantly lower than HEO, are less prone to the cubic to tetragonal structural distortion, suggesting that the configurational entropy has not the central role as stabilizing factor of the rock-salt structure.

As one kind of smart material, thermogelling polymers find applications in biofabrication, drug delivery and regenerative medicine. Here, we reported on a novel thermosensitive hydrogel which can be 3D printed using extrusion based printing. Gel strength was found around 3kPa storage modulus with pronounced shear thinning and rapid recovery after stress. Addition of clay nanoparticles (Laponite XLG) improved the rheological profile further. Human adipose derived stem cells were added to the hydrogel matrix, which remained fully viable after printing. Therefore, the presented materials adds to the available material toolbox for 3D bioprinting.

Published: April 2021

Protein-protein complex assembly is one of the major drivers of biological response. Understanding the mechanisms of protein oligomerization/dimerization would allow one to elucidate how these complexes participate in biological activities and could ultimately lead to new approaches in designing novel therapeutic agents. However, determining the exact association pathways and structures of such complexes remains a challenge. Here, we use parallel tempering metadynamics simulations in the well-tempered ensemble to evaluate the performance of Martini 2.2P and Martini open-beta 3 (Martini 3) force fields in reproducing the structure and energetics of the dimerization process of membrane proteins and proteins in an aqueous solution in reasonable accuracy and throughput. We find that Martini 2.2P systematically overestimates the free energy of association by estimating large barriers in distinct areas, which likely leads to overaggregation when multiple monomers are present. In comparison, the less viscous Martini 3 results in a systematic underestimation of the free energy of association for proteins in solution, while it performs well in describing the association of membrane proteins. In all cases the near-native dimer complexes are identified as minima in the free energy surface albeit not always as the lowest minima. In the case of Martini 3 we find that the spurious supramolecular protein aggregation present in Martini 2.2P multimer simulations is alleviated and thus this force field may be more suitable for the study of protein oligomerization. We propose that the use of enhanced sampling simulations with a refined coarse-grained force field and appropriately defined collective variables is a robust approach for studying the protein dimerization process, although one should be cautious of the ranking of energy minima.

Pengaruh Preprocessing Terhadap Klasifikasi Diabetic Retinopathy dengan Pendekatan Transfer Learning Convolutional Neural Network
Authors: Widyaya Juan Elisha , Budi Setia
Published: April 2021

Diabetic retinopathy (DR) is eye diseases caused by diabetic mellitus or sugar diseases. If DR is detected in early stage, the blindness that follow can be prevented. Ophthalmologist or eye clinician usually decide the stage of DR from retinal fundus images. Careful examination of retinal fundus images is time consuming task and require experienced clinicians or ophthalmologist but a computer which has been trained to recognize the DR stages can diagnose and give result in real-time manner. One approach of algorithm to train a computer to recognize an image is deep learning Convolutional Neural Network (CNN). CNN allows a computer to learn the features of an image, in our case is retinal fundus image, automatically. Preprocessing is usually done before a CNN model is trained. In this study, four preprocessing were carried out. Of the four preprocessing tested, preprocessing with CLAHE and unsharp masking on the green channel of the retinal fundus image give the best results with an accuracy of 79.79%, 82.97% precision, 74.64% recall, and 95.81% AUC. The CNN architecture used is Inception v3.

Authors: Hariadi Fajar
Published: April 2021

Redundancy Link merupakan upaya pencegahan permasalahan jaringan dengan menyediakan jalur cadangan terhadap jalur utama yang digunakan. Redundancy Link untuk layer 3 Network memiliki beberapa metode, salah satunya adalah Hot Standby Router Protokol (HSRP). Secara default HSRP tidak memiliki fitur Load Balancing, oleh karena itu dalam tulisan ini akan dibahas penerapan Load Balancing menggunakan beberapa Group HSRP secara manual pada empat buah VLAN. Hasil yang didapat adalah proses transisi penanganan failover dan recovery berlangsung mulus dan jarang terjadi hilangnya packet atau time out, namun terjadi peningkatan delay selama beberapa saat sebelum akhirnya kembali normal. Selain itu didapati bahwa terjadi perbedaan yang cukup signifikan antara waktu failover dan recovery yang diperlukan ketika terjadi permasalahan jaringan pada satu interface fisik dan interface dengan empat sub-interface yang mewakili empat Group HSRP untuk masing-masing VLAN. Dimana penanganan failover antara keduanya memiliki selisih waktu 6.35 detik, sedangkan waktu recovery memiliki selisih waktu sebesar 6.58 detik.
