We present the first measurement of the mass function of free-floating planets (FFPs), or very wide orbit planets down to an Earth mass, from the MOA-II microlensing survey in 2006–2014. Six events are likely to be due to planets with Einstein radius crossing times t
E < 0.5 days, and the shortest has t
E = 0.057 ± 0.016 days and an angular Einstein radius of θ
E = 0.90 ± 0.14 μas. We measure the detection efficiency depending on both t
E and θ
E with image-level simulations for the first time. These short events are well modeled by a power-law mass function,

We report the discoveries of low-mass free-floating planet (FFP) candidates from the analysis of 2006–2014 MOA-II Galactic bulge survey data. In this data set, we found 6111 microlensing candidates and identified a statistical sample consisting of 3535 high-quality single-lens events with Einstein radius crossing times in the range 0.057 < t
E/days < 757, including 13 events that show clear finite-source effects with angular Einstein radii of 0.90 < θ
E/μas < 332.54. Two of the 12 events with t
E < 1 day have significant finite-source effects, and one event, MOA-9y-5919, with t
E = 0.057 ± 0.016 days and θ
E = 0.90 ± 0.14 μas, is the second terrestrial-mass FFP candidate to date. A Bayesian analysis indicates a lens mass of

The microlensing detection efficiency for low-mass planet events depends on both the Einstein radius crossing times and the angular Einstein radii, so we have used image-level simulations to determine the detection efficiency dependence on both t
E and θ
E. This allows us to use a Galactic model to simulate the t

Neutrinos and Asteroseismology of Stars over the Helium Flash
Authors: Capelo Diogo , Lopes Ilídio
Published: August 2023

The helium flash, occurring in stars of 0.6–2.0 M
⊙ at the end of the red giant branch, is not observable via optical means due to the energy of the process being used to lift the core out of degeneracy. Neutrinos, which are linked to the ignition of reactions triggered during the flash and serve as the only cooling process in the inert core, can help characterize changes in internal structure. In this work, we create 18 stellar models across three mass and six metallicity values, chosen in the context of the stellar abundance problem, to compare the evolutionary path up to and probe the helium flash by conducting a detailed study of neutrino emission throughout this crucial phase of stellar evolution. We demonstrate how thermal neutrino emissions could have an imprint on global asteroseismic parameters and use them as an additional tool to infer the impact of compositional changes. We find that a precision of 0.3 μHz in the determination of Δν is enough to distinguish between between the two most prominent solar composition models and confirm that asteroseismic observation can be enough to classify a star as undergoing the process of helium subflashes. We also predict nuclear neutrino emission fluxes and their evolution for all relevant sources.

With the successful impact of the NASA Double Asteroid Redirection Test (DART) spacecraft in the Didymos–Dimorphos binary asteroid system, we provide an initial analysis of the post-impact perturbed binary asteroid dynamics. To compare our simulation results with observations, we introduce a set of “observable elements” calculated using only the physical separation of the binary asteroid, rather than traditional Keplerian elements. Using numerical methods that treat the fully spin–orbit-coupled dynamics, we estimate the system’s mass and the impact-induced changes in orbital velocity, semimajor axis, and eccentricity. We find that the changes to the mutual orbit depend strongly on the separation distance between Didymos and Dimorphos at the time of impact. If Dimorphos enters a tumbling state after the impact, this may be observable through changes in the system’s eccentricity and orbit period. We also find that any DART-induced reshaping of Dimorphos would generally reduce the required change in orbital velocity to achieve the measured post-impact orbit period, and will be assessed by the ESA Hera mission in 2027.

AIM: This study aims to determine serum 25(OH)D levels in children with chronic tonsillitis at Dr. Hasan Sadikin Bandung General Hospital.
METHODS: This descriptive and cross-sectional study was conducted in patients with chronic tonsillitis aged
3–15 years from August 26, 2021, to April 26, 2022. The exclusion criteria include children who consumed Vitamin D for the past month, are in ongoing treatment for chronic tonsillitis, and have comorbidities that affect Vitamin D serum. Characteristics were taken from anamnesis, while Vitamin D serum was analyzed using the ELISA method, then data were presented in numbers and percentages.
RESULTS: The average serum level of 25(OH)D was 16.43 ± 3.5 ng/mL. All 44 subjects suffered from a lack of Vitamin D, categorized as deficiency, insufficiency, and severe deficiency, at 72.7%, 22.7%, and 4.6%, respectively. The majority of the cases were boys compared to girls, with 70.5% and 29.5%, respectively.
CONCLUSION: All children with chronic tonsillitis were found to have 25(OH)D serum below the normal level, with an average of 16.43 ± 3.5 ng/mL, especially in boys aged 3–10 years.
Assessing the economic efficiency of green investments in the context of sustainable development of the territory
Authors: Kurdyukov Vladimir , Ovcharenko Alla
Published: August 2023

This article proposes theoretical and analytical foundations for the economic assessment of the results of green investments in terms of promoting territorial sustainability. The green investments are presented as resources aimed at reducing the economic damage from environmental pollution through the creation of conditions or direct impact activities. However, the discounting application distorts their significance. The result of real green investment is capital, which is often specific and difficult to assess. It distinguishes them markedly from other investments. Green investments do not require directive advantages, such as a social discount rate. It is necessary to address the results of green investment in terms of their value for the sustainability of socio-economic systems. The accounting of total costs and results for the system when making decisions will allow for reducing territorial exploitation by social groups. Overcoming the discounting contradictions while assessing the economic effectiveness of green investments requires improving the adequacy of green investments results' evaluation in terms of the territory's sustainability transition, the differentiation of discount rates for various results, their costs and the years of their appearance and the use of compounding to assess the accumulation of the total result of a project based on the analysis of its entire life cycle. The study proposes a system for assessing the economic value of the growth of an ecosystem's assimilation potential and the consequences of its decline in relation to the costs of building the assimilation potential, the increase in the maximum allowable load on the ecosystem and the environmental pollution damage. To estimate the economic effect of the growth of an ecosystem's assimilation potential, it is necessary to consider the rate of return for its owner. The results of this study will allow for reducing the assessment distortions and informational limitations of the managerial decision-making process.

When using machine-learning techniques to determine algorithms or ranking models that identify student satisfaction, algorithms are often trained and tested on a single data set, leading to bias in their performance metrics. This article aims to identify the best algorithm to classify the satisfaction of university students applying the K-fold cross-validation technique, comparing the error rates of the performance metrics before and after its application. The method used began with the collection of student opinions on the teaching performance of the social network Twitter during an academic semester. Then, sentiment analysis was used for data processing, through which it was possible to categorize the opinions of the students into “satisfied” or “dissatisfied.” The results showed that the algorithm with the lowest error rate in its performance metric was the support vector machine (SVM). In addition, it was identified that its classification probability reached an accuracy of 91.76%. It is concluded that SVM classification using K-fold cross-validation will contribute to determining which factors associated with the teacher’s didactic strategies should be improved in each class session, since traditional surveying techniques have shortcomings.

Choice of Therapy in Obese Type 2 Diabetes
Authors: Jyotsna Viveka P. , Deshmukh Shweta
Published: August 2023

Obesity is a chronic metabolic disease affecting individuals all over the world and is known to be a main risk factor for type 2 diabetes (T2D). In countries like India, T2D occurs with a lower degree of obesity as compared to T2D in western countries. It is important to tackle obesity in T2D because studies have shown that modest weight loss leads to improvements in glycemic levels, thereby reducing the risk of diabetes-related complications and comorbidities. Obesity complicates the management of diabetes, particularly the goal of achieving tight glycemic control as it is associated with insulin resistance. In this article, we are going to discuss choice of therapies in the management of T2D in obese individuals. In patients with T2D and obesity treatment approach should be individualized and it includes intensive lifestyle intervention, pharmacologic therapy, and/or metabolic surgery. Additional attention should be given to concomitant therapies for other comorbidities which may further lead to weight gain. Considering the strong link between obesity and T2D, the first choice of therapy after lifestyle modification should be glucose-lowering agents, which promote weight reduction or are at least weight neutral. Metformin, alpha-glucosidase inhibitor, sodium-glucose co-transporter 2 (SGLT-2) inhibitor, glucagon-like peptide–1 receptor agonist (GLP-1 RA), and amylin mimetic promote weight loss along with additional cardiovascular benefits of GLP-1 RA, SGLT-2 inhibitor, and improved renal outcomes with SGLT-2 inhibitor. Weight neutral therapies include dipeptidyl peptidase-4 inhibitors and fixed ratio insulin/GLP-1 RA combination therapies (insulin degludec/liraglutide, insulin glargine and lixisenatide) can also be considered as they help to limit weight gain. Therapies such as thiazolidinedione, insulin secretagogue (sulfonylurea and meglitinide), and insulin are less suitable for individuals with obesity and T2D as they are associated with weight gain.

Authors: Abah Austin E. , Owens Peninnah , Maduike Eberechukwu
Published: August 2023

Background

Head lice (Pediculosis humanus capitis) infestation is of public health importance, associated with poor hygiene. This study was to determine the prevalence of head lice among a university community in Port Harcourt.

Materials and Methods

Random sampling technique and accidental sampling technique were used. A total of 300 people, age 16–40years were sampled from April to July 2021. Hair and scalp were examined using a magnifying glass and combing the hair with a fine-tooth comb on white paper facilitated the visualization and collection of adult lice and nymphs. Samples were preserved with 70% ethanol in a small size bottle and viewed under a stereomicroscope.

Results

Overall, the prevalence was 17%. The infestation was higher (18.2%) within the age group of 21–25years followed by those within the age group of 16–20 years (17.4%). More females (21.6%) were infected than males (9.0%). Based on the level of education, undergraduates (21%) were more infected followed by those with first degree (11.1%). Prevalence based on sex was statistically significant (P<0.002), but age (P=0.142) and the level of education (P=0.566) was not significant.

Conclusion

The prevalence of head lice infestation is high in Port Harcourt suggesting that Pediculus humanis is reemerging in the city and among the older population. Enlightenment campaign is recommended to contain further spread.

Nano self-cleaning system review is presented in this paper. To achieve superhydrophobicity on a surface, it needs to be both rough and possess low surface energy. In this study, paraffin wax nanoparticles were used to create a hierarchically structured surface on cotton fabric, resulting in a superhydrophobic surface. Candle soot nanoparticles were also used to deposit superhydrophobic coatings onto smooth and micro-rough steel surfaces, demonstrating significant promise for use in high-temperature and corrosive environments. The coatings exhibited outstanding chemical and thermal stabilities, as well as effective self-cleaning abilities, making them ideal for industrial applications. Results from testing showed that the coatings created with 100 mg of candle soot nanoparticles in suspension were stable when hit by water jets, and demonstrated strong water repellent and self-cleaning qualities. This study provides an affordable and efficient technique for creating superhydrophobic coatings with a wide range of potential applications.

In this paper, the study on applications of radio frequency nano antenna energy conversion and supercapacitors is presented. Radio Frequency (RF) signals are a form of electromagnetic radiation with wavelengths greater than 3 meters. Initially used in wireless communication devices like radios and walkie-talkies, RF signals have found their way into energy conversion and storage applications. When RF signals are received by an antenna with coupled capacitors and a rectifier circuit, they generate a potential difference of a few millivolts. This potential difference can be used as a stable source of energy to power low-voltage applications through ambient RF radiation, and excess energy can be stored in electrochemical storage systems like supercapacitors and lithium-ion batteries. While this technology is currently limited to low-power applications, it has immense potential in various fields such as medicine, automotive industry, military applications, and more. Researchers are currently working to improve the energy density of supercapacitors by modifying their electrode materials using nanotechnology. One promising material is lignin, derived from wood fibers, which has shown great performance in tests and is expected to be a low-cost solution for high-performance batteries and supercapacitors. As the renewable energy sector continues to advance, we can expect to see more useful applications based on RF nano antennas and micro/nano-sized supercapacitors. The work done & presented in this paper is the result of the mini-project work that has been done by the first sem engineering students of the college and as such there is little novelty in it and the references are being taken from various sources from the internet, the paper is being written by the students to test their writing skills in the starting of their engineering career and also to test the presentation skills during their mini-project presentation.

Published: August 2023

The precise identification of blood vessels in fundus is crucial for diagnosing fundus diseases. In order to address the issues of inaccurate segmentation and low precision in conventional retinal image analysis for segmentation methods, a new approach was developed.The suggested method merges the U-Net and Dense-Net approaches and aims to enhance vascular feature information. To achieve this, the method employs several techniques such asHistogram equalization with limited contrast enhancement, median filtering, normalization of data, and morphological transformation. Furthermore, to correct artifacts, the method utilizes adaptive gamma correction. Next, randomly selected image blocks are utilized as training data to expand the data and enhance the generalization capability. The Dice loss function was optimized using stochastic gradient descent to improve the accuracy of segmentation, and ultimately, the Dense-U-net model was used for performing the segmentation. The algorithm achieved specificity, accuracy, sensitivity, and AUC of 0.9896, 0.9698, 0.7931, and 0.8946 respectively, indicating significant improvement in vessel segmentation accuracy, particularly in identifying small vessels.

Ovarian cancer is a type of cancer with a high incidence and mortality rate in Indonesia and worldwide. C-reactive protein (CRP) is an inflammatory marker meanwhile albumin is an indicator of nutritional deficiencies in ovarian cancer. This study is a diagnostic test for ovarian cancer in women aged >18 years and without previous history of ovarian cancer who underwent laparotomy or laparoscopy at Prof. Ngoerah General Hospital, Denpasar. Samples were taken by consecutive sampling. CRP examination was carried out in the laboratory by immunoturbidimetry method using the CRP Latex Kit (Roche) and measured using a Cobas integra 501 at a wavelength of 552 nm. The gold standard to diagnosed ovarian cancer was according to histopathological examination. A total of 69 women with ovarian tumors were recruited into the study which consisted of 40 ovarian cancers and 29 benign ovarian tumors. A significantly higher median CRP/Albumin ratio was found in ovarian cancer patients compared to benign ovarian tumors (6.9 vs 0.45; p=0.001). The optimal CRP/albumin ratio cut-off value was 1.34.

Endometrial receptivity is highly correlated with the implantation rate, whereby in Indonesia, the implantation rate among in vitro fertilisation programs is still low, around 19.3%. Antagonist ovarian stimulation protocol can disrupt physiological endocrine milieu by the presence of supra-physiological levels of estrogen and progesterone, both of which are thought to indirectly affect the expression of adhesion molecule cells. Homeobox A 10 (HOXA10) is among one of the biomarkers used to assess endometrial receptivity. The role of HOXA10 is critical during the stage of endometrial development and embryo implantation, both in mice and human. This molecule is thought to work optimally by administering autologous platelet rich plasma (PRP) to the damaged endometrium. The aim of this study was to prove that administration of PRP in an antagonist protocol HOXA10 expression in the endometrium of Wistar rats higher than without PRP. This research was an experimental study. The design for this study was randomized posttest only controlled group, using female Wistar-strain rats type. A total of 40 Wistar rats whose ovary were stimulated by the GnRH antagonist protocol were divided into 2 groups, 20 rats as intervention group in which PRP administration was done and 20 rats as control group. It was found that during the study, there was no significant difference between intervention and control group regarding age and body weight of the Wistar rats, both at the start and at the end of the study. The results of HOXA10 H-score in the intervention group was 3.15 (2.86-3.52) and in the control group was 1.68 (1.43-2.18) (p <0.05). Administration of PRP to ovarian stimulation with an antagonist protocol showed significantly higher expression of endometrial HOXA10 in Wistar rats than without PRP administration.

This thesis investigates the portfolio optimization process using the Markowitz model on the SRI-KEHATI index, an esteemed sustainable investment index. The study aims to explore the potential advantages of incorporating environmental, social, and governance (ESG) factors into portfolio construction. By leveraging historical financial data and reliable ESG metrics, this research develops optimized portfolios that strike a balance between risk and return while adhering to the sustainability criteria of the SRIKEHATI index. The methodology encompasses the collection of credible ESG data and financial information for the constituents of the SRIKEHATI index. The Markowitz model is subsequently employed to analyze the risk and return characteristics of each asset within the portfolio. Through the application of optimization algorithms, the study seeks to identify the optimal asset allocation that maximizes risk-adjusted returns, taking into account the ESG criteria outlined by the SRI-KEHATI index. The outcomes of this research provide valuable insights into the effectiveness of portfolio optimization techniques within the realm of sustainable investing. By considering both financial metrics and ESG factors, investors can construct portfolios that align with their sustainability objectives while optimizing risk and return. The findings shed light on the performance of the optimized portfolios and compare them with conventional approaches, thereby demonstrating the potential benefits of integrating ESG considerations into portfolio decision-making. Additionally, this study examines the practical implications associated with implementing sustainable portfolio strategies based on the SRI-KEHATI index. Overall, this thesis contributes to the expanding body of knowledge on sustainable investing and portfolio optimization, specifically focusing on the SRI-KEHATI index. It provides valuable insights for investors, asset managers, and policymakers interested in sustainable investment strategies. Furthermore, it offers a framework for incorporating ESG considerations into the portfolio construction process using the Markowitz model, thereby aiding in the development of more robust and sustainable investment portfolios.

Ülkelerin sürdürülebilir kalkınmaya önem vermesiyle çevrenin iyileşmesi ve sınırlı kaynakların kontrol altına alınması sağlanarak ekonomilerin gelişmesi sağlanabilir. Özellikle Avrupa Birliği ülkelerinin sürdürülebilir kalkınma ile ilgili politikaları küresel ekonomiyi etkileyebildiğinden dolayı Avrupa Birliği ülkelerinin sürdürülebilir kalkınma performanslarının ölçülmesi önem arz etmektedir. Bu bağlamda araştırmada, Avrupa Birliği ülkelerinin en son ve güncel olan Dönüşüm Performansı Endeksi (Transaction Performance Index - TPI) bileşenlerine ait değerler üzerinden söz konusu ülkelerin sürdürülebilir kalkınma performansları MEREC tabanlı WEDBA yöntemi ile ölçülmüştür. Bulgulara göre ilk olarak MEREC yöntemi ile ülkelere göre en önemli TPI bileşeninin ‘‘çevresel dönüşüm’’ olduğu tespit edilmiştir. İkinci olarak ise MEREC tabanlı WEDBA yöntemine göre en fazla sürdürülebilir kalkınma performansına sahip ilk üç ülkenin Danimarka, İrlanda ve Malta, buna karşın en az performansa sahip ilk üç ülkenin ise GKRK, Finlandiya ve Estonya olduğu gözlenmiştir. Araştırmada ayrıca MEREC tabanlı WEDBA yöntemi kapsamında ülkelerin ortalama sürdürülebilir kalkınma performansları hesaplanmış ve ortalama performans değerinden az performansa sahip olan ülkelerin küresel ekonomiye katkılarının daha fazla olması için sürdürülebilir kalkınma performanslarını artırmaları gerektiği değerlendirilmiştir. Son olarak yöntem açısından duyarlılık ve ayırım uzaklığı analizlere göre ülkelerin sürdürülebilir kalkınma performansları TPI kapsamında MEREC tabanlı WEDBA yöntemi ile ölçülebileceği sonucuna ulaşılmıştır.
