Predictive crypto-asset automated market maker architecture for decentralized finance using deep reinforcement learning
Authors: Lim Tristan
Published: September 2024

This study proposes a quote-driven predictive automated market maker (AMM) platform with on-chain custody and settlement functions, alongside off-chain predictive reinforcement learning capabilities, to improve the liquidity provision of real-world AMMs. The proposed architecture augments Uniswap V3, a cryptocurrency AMM protocol, by using a novel market equilibrium pricing to reduce divergence and slippage losses. Furthermore, the proposed architecture involves a predictive AMM capability, for which a deep hybrid long short-term memory (LSTM) and Q-learning reinforcement learning framework is used. It seeks to improve market efficiency through obtaining more accurate forecasts of liquidity concentration ranges, where liquidity starts moving to expected concentration ranges prior to asset price movement; thus, liquidity utilization is improved. The augmented protocol framework is expected to have practical real-world implications through (1) reducing divergence loss for liquidity providers; (2) reducing slippage for crypto-asset traders; and (3) improving capital efficiency for liquidity provision for the AMM protocol. The proposed architecture is empirically benchmarked against the well-established Uniswap V3 AMM architecture. The preliminary findings indicate that the novel AMM framework offers enhanced capital efficiency, reduced divergence loss, and diminished slippage, which could potentially address several of the challenges inherent to AMMs.
Factors affecting the development of cystoid macular edema following pars plana vitrectomy with silicone oil placement: a retrospective cohort study
Authors: ElSheikh Reem H. , Zhang Sairi , Chauhan Muhammad Z. , Sanders Riley N. , Uwaydat Sami H.
Published: September 2024

Background

Cystoid macular edema (CME) can develop following silicone oil placement in complex vitreoretinal surgeries, contributing to poor visual outcomes. In this study, we investigated the clinical and surgical characteristics associated with the development of CME following the use of silicone oil (SO) in pars plana vitrectomy (PPV) surgeries.

Methods

We conducted a retrospective chart review of patients who underwent implantation of SO during PPV from 2010 to 2020 by a single surgeon. Patient demographics, type of oil, duration of oil tamponade, retinectomy size, diabetic status, lens status, prior panretinal photocoagulation, visual acuity, and incidence of CME were reviewed.

Results

This study included 43 eyes from 40 patients who underwent SO tamponade for retinal detachment (RD) surgery. The mean duration of SO tamponade was 15.7 ± 12.7 months (range: 1–58 months). The most common indication for surgery was diabetic tractional RD (32.7%), followed by traumatic RD (16.3%) and rhegmatogenous RD with proliferative vitreoretinopathy (11.6%). Of the 43 eyes, 18 (41.9%) developed CME for the first time after PPV with SO placement, with 8 (44%) resolving within a year of oil removal. The mean duration for the development of CME was 9 months. A logistic regression model showed that a scleral buckle procedure and poor initial vision were statistically significant factors for predicting the development of CME (ORs: 11.65 and 16.06, respectively). Overall, 91% of the patients had stable or improved vision after surgery.

Conclusions

The use of a scleral buckle procedure and poor initial vision are significant factors for predicting CME following silicone oil tamponade in PPV surgeries, with 41.9% of patients developing CME with an average duration of 9 months. Recognizing such factors can lead to early monitoring and prompt management of CME.

Authors: Shimizu Kota , Yamada Toru , Moriyama Kazuhiro , Kato China , Kuriyama Naohide , Hara Yoshitaka , Kawaji Takahiro , Komatsu Satoshi , Morinishi Yohei , Nishida Osamu , Nakamura Tomoyuki
Published: September 2024

Background

Venous air trap chamber designs vary considerably to suit specific continuous renal replacement therapy circuits, with key variables including inflow design and filter presence. Nevertheless, intrachamber flow irregularities do occur and can promote blood coagulation. Therefore, this study employed computational fluid dynamics (CFD) simulations to better understand how venous air trap chamber designs affect flow.

Methods

The flow within a venous air trap chamber was analyzed through numerical calculations based on CFD, utilizing large eddy simulation. The working fluid was a 33% glycerin solution, and the flow rate was set at 150 ml/min. A model of a venous air trap chamber with a volume of 15 ml served as the computational domain. Calculations were performed for four conditions: horizontal inflow with and without a filter, and vertical inflow with and without a filter. Streamline plots and velocity contour plots were generated to visualize the flow.

Results

In the horizontal inflow chamber, irrespective of filter presence, ultimately the working fluid exhibited a downstream vortex flow along the chamber walls, dissipating as it progressed, and being faster near the walls than in the chamber center. In the presence of a filter, the working fluid flowed uniformly toward the outlet, while in the absence of a filter the flow became turbulent before reaching the outlet. These observations indicate a streamlining effect of the filter.

In the vertical inflow chamber, irrespective of filter presence, the working fluid flowed vertically from the inlet into the main flow direction. Part of the working fluid bounced back at the chamber bottom, underwent upward and downward movements, and eventually flowed out through the outlet. Stagnation was observed at the top of the chamber. Without a filter, more working fluid bounced back from the bottom of the chamber.

Conclusions

CFD analysis estimated that the flow in a venous air trap chamber is affected by inflow method and filter presence. The “horizontal inflow chamber with filter” was identified as the design creating a smooth and uninterrupted flow throughout the chamber.

Authors: Vieira Pedro Henrique Acioly Guedes Peixoto , Regis Wanessa Fernandes Matias , Praciano Davi Costa Melo , Marinho Isabelle Montenegro Alves , De Castro Raquel Moreira Veiga , Rodrigues Lidiany Karla Azevedo
Published: September 2024

Background: Hidden caries is characterized by lesions that cannot be detected exclusively through clinical examination, requiring the use of radiographic examinations for their identification. Case Report: This case study presents the management of two lower molars with microcavitations and enamel shading. Additionally, the presence of a pigmented occlusodistal fissure in one of the elements is noted. The radiographic examination revealed an extensive carious lesion in the dentin, which was not in proximity to the pulp and did not exhibit any periapical lesions. This finding led to the diagnosis of hidden caries. The technique of selective removal of the carious tissue was chosen due to its depth and the potential risk of pulp exposure. Then, the dentin/pulp complex was protected, and the definitive restoration was performed. Conclusion: The progression of hidden carious lesions can lead to tooth destruction without visible clinical signs. Treatment should adhere to minimally invasive dentistry principles to preserve tooth structure and reduce the risk of pulp exposure.

Authors: Kechagia Polyxeni
Published: September 2024

Abstract
Multinational enterprises try to reduce operating costs and invest their capital in countries with low labor costs. However, although low labor cost is considered a determinant for foreign direct investment inflows, it is often associated with illegal activities, namely child labor. Motivated by the limited empirical evidence on the association between child labor and foreign direct investment inflows, the present research aims to investigate child labor in the European Union countries as a determinant of foreign direct investment inflows from 2002 to 2021 through a panel data analysis. The research contributes to the existing knowledge by extending an empirical model and providing empirical evidence for a group of developed countries. It is observed that the Foreign Direct investment inflows in the countries of the European Union are affected by socioeconomic conditions and institutional factors.

Abstract
Over the past two decades, e-learning has emerged as a crucial aspect of Higher Education Institutions (HEIs), necessitating the establishment of an e-Learning Support Center (eLSC) as a fundamental part of the university's infrastructure. An eLSC provides centralized assistance for the digital transformation of education at an institutional level. Considering this development, our study explores the current state in various HEIs and, through the analysis and synthesis of best practices, concludes with a set of specifications that define a qualitative and effective eLSC. Our investigation covers a range of topics that require strategic management and decision-making at an institutional level. These include the key components that regulate the functions, services, administration, and roles within an eLSC, as well as the challenges associated with establishing such a unit. Methodologically, our research relies on the qualitative analysis of secondary data, focusing specifically on the content analysis of websites of corresponding eLSCs at both a national and international level. This approach enables us to gain insights into the characteristics of effective eLSCs across various institutional contexts, thereby contributing to the broader discourse on e-learning and its integration into higher education.

Περίληψη
Διαφορετικά περιβάλλοντα προγραμματισμού ισχυρίζονται ότι έχουν σχεδιαστεί για να διδάξουν υπολογιστική σκέψη (ΥΣ) και δεξιότητες κωδικοποίησης σε παιδιά προσχολικής ηλικίας. Ωστόσο, η έρευνα για την αποτελεσματικότητά τους βρίσκεται ακόμη σε αρχικό στάδιο. Χρησιμοποιώντας μια διδακτική παρέμβαση τριών εβδομάδων, η παρούσα μελέτη διερεύνησε την αποτελεσματικότητα του ScratchJr στην προώθηση της ΥΣ και των βασικών δεξιοτήτων κωδικοποίησης σε παιδιά προσχολικής ηλικίας (Ν=32, 4-6 ετών). Αν και η μέση επίδοση της ομάδας ελέγχου (M=7.07, SD=2.58) στον προέλεγχο ήταν σημαντικά υψηλότερη από αυτή της πειραματικής ομάδας (M=5.35, SD=1.58), t(22,64) = 2.23, p=.036, μετά την παρέμβαση και οι δύο μέθοδοι διδασκαλίας αποδείχθηκαν αποτελεσματικές. Ωστόσο, η ανάλυση δεδομένων αποκάλυψε μια στατιστικά σημαντική βελτίωση σε παιδιά προσχολικής ηλικίας των οποίων η εκπαιδευτική παρέμβαση περιελάμβανε το ScratchJr. Τα αποτελέσματα υποστηρίζουν την αποτελεσματικότητα του συγκεκριμένου περιβάλλοντος προγραμματισμού στην ανάπτυξη δεξιοτήτων ΥΣ και κωδικοποίησης σε παιδιά προσχολικής ηλικίας.
Abstract
Numerous distinct programming environments purport to be tailored for instructing preschool children in computational thinking (CT) and coding proficiencies. Nevertheless, research into their efficacy remains at an early stage. This study, utilizing a didactic intervention spanning three weeks, endeavors to explore the effectiveness of ScratchJr in fostering CT and fundamental coding abilities among a cohort of preschool children (N=32, aged 4-6 years). While the initial performance mean of the control group (M=7.07, SD=2.58) significantly surpassed that of the experimental group (M=5.35, SD=1.58), t(22.64) = 2.23, p=.036, an approximately commensurate performance mean was observed between the two groups following the intervention. However, an in-depth examination of the data unveiled a statistically significant enhancement in the preschool children who underwent educational intervention with ScratchJr. These findings corroborate the effectiveness of this particular programming environment in cultivating CT and coding competencies in preschool-aged children.

Διαχρονική εξέλιξη του θεσμού του διευθυντή στην Ελλάδα και τα προσόντα που απαιτούνται
Authors: Κωνσταντινίδης Θεόδωρος
Published: September 2024

Το σύγχρονο και συνεχώς μεταβαλλόμενο και εξελισσόμενο κοινωνικό πολιτικό περιβάλλον της χώρας μας επηρεάζει και το χώρο της εκπαίδευσης που αποτελεί έναν ζωντανό και ανοιχτό προς την κοινωνία οργανισμό. Επιβάλλει διευθυντές με δεξιότητες, ιδιαίτερα προσωπικά χαρακτηριστικά, επιστημονικά θωρακισμένους και γνωσιακά καταρτισμένους σε θέματα δημόσιας και σχολικής διοίκησης που θα μπορέσουν να ανταποκριθούν σε νεοτερισμούς χαράσσοντας νέο δρόμο και νέους ορίζοντες στα εκπαιδευτικά δρώμενα της χώρας μας. Η αποδοχή των διευθυντών τόσο εντός της σχολικής μονάδας όσο και ευρύτερα εξαρτάται από το επίπεδο των προσόντων, γνώσεων και της πρακτικής εφαρμογής τους. Με το τρόπο αυτό θα δημιουργηθεί ένα αποτελεσματικό, αποδοτικό και παραγωγικό σχολείο που θα πετυχαίνει τους θεσπισμένους στόχους, βασιζόμενο πάντοτε σε ηθικές αρχές και αξίες.Οι διευθυντές των ελληνικών σχολικών μονάδων βρίσκονται αντιμέτωποι με προκλήσεις και η αντιμετώπισή τους καθορίζει τον τρόπο διοίκησης του σχολείου  και ενδεχομένως την μελλοντική τους πορεία  στη νέα πραγματικότητα που διαμορφώνεται καθημερινά.  Ο διευθυντής βρίσκεται στην κορυφή της σχολικής διοικητικής πυραμίδας και είναι τόσο διοικητικός όσο και παιδαγωγικός υπεύθυνος στο χώρο του σχολείου (Αριθμ. Φ. 353.1./324/105657/Δ1/ΦΕΚ 1340/16/10/2002). Όπως τονίζει η Σπυροπούλου (2010), από τις αρχές  του ‘80 έως και σήμερα κύριο κριτήριο για την κατάκτηση διευθυντικής θέσης είναι τα έτη εκπαιδευτικής προϋπηρεσίας. Παρά τις προσπάθειες που έχουν γίνει από την πολιτεία κατά καιρούς ώστε να αποκτήσει πιο επιστημονικό χαρακτήρα η διαδικασία επιλογής, δεν έχει κατορθωθεί ακόμη ένας σχεδιασμός όμοιος, ώστε να μπορεί να αποτελέσει βάση για μια πιο προοδευτική προσέγγιση.

Spatio-temporal occurrence, burden, risk factors and modelling methods for estimating scrub typhus burden from global to subnational resolutions: a systematic review protocol
Authors: Wang Qian , Sartorius Benn , Day Nicholas Philip John , Maude Richard James
Published: September 2024

Background Scrub typhus is a neglected life-threatening vector-borne disease mainly caused by the bacterium Orientia tsutsugamushi, which is occasionally transmitted to humans during feeding of larval mites. It has been estimated that more than 1 billion persons are potentially threatened and 1 million clinical cases occur annually across the world; however, it is unclear how this estimate was computed (and what the original source was) and much remains unknown regarding its global burden and risk factors. This systematic review aims to provide a comprehensive overview of the spatial-temporal distribution of scrub typhus, associated burden and risk factors at global, national and subnational resolutions, and to review the burden estimation models used at those different scales. Methods A systematic search for literature on scrub typhus occurrence, risk factors and modelling methods will be conducted. PubMed and five other databases will be searched for published literature, and Google Scholar and nine other databases will be used to search for grey literatures. All titles/abstracts of the searched records will be separately assessed by two reviewers, who will then screen the full-text of potential records to decide eligibility. A pre-formatted spreadsheet will be used by one reviewer to extract data from qualifying research, with a second reviewer checking the results. Data will be tabulated, synthesized descriptively, and summarized narratively for each review question. Where appropriate, meta-analyses will be conducted. The risk of bias will be assessed, and potential publication bias will be detected. Discussion This review will provide a comprehensive understanding of the current occurrence, spatial-temporal distribution, and burden of scrub typhus, identify associated risk factors from global to subnational resolutions, consolidate the best practice modeling framework(s) to estimate the burden of scrub typhus at various geographic/temporal resolutions, and decompose the relative contributions of various risk factors at scale.

Published: September 2024

The purpose of this review is to evaluate the effects of oral collagen supplementation on joint function, muscle recovery, and overall musculoskeletal health in athletes. Collagen, a key protein in the body, is essential for the health of joints, muscles, and connective tissues. As collagen production declines with age, supplementation has become a promising strategy for improving athletic performance and reducing injury risk. This review analysed recent studies published from 2016 onwards, focusing on the impact of collagen supplementation, particularly in combination with regular training. The research involved a comprehensive literature search in the MEDLINE database, initially identifying 82 records, with 39 undergoing quality assessment. Ultimately, 26 studies met the inclusion criteria and were included in the final analysis. The findings indicate that collagen peptides significantly enhance joint stability, reduce pain, and accelerate recovery from injuries such as Achilles tendinopathy. Moreover, collagen supplementation combined with resistance training was shown to improve muscle strength, body composition, and recovery markers more effectively than training alone. The review also highlights collagen's role in extracellular matrix remodelling and anti-inflammatory responses, offering potential benefits in tissue repair and injury prevention. These results suggest that collagen supplementation could be a valuable addition to athletes' training regimens, warranting further research to optimize dosing strategies and explore its mechanisms of action.

Traumatic Brain Injury (TBI) was characterized  as alternation in brain function or any other sign of brain pathology resulting from external force. Sport-related traumatic brain injury (SR-TBI) calculated as up to 20% of all TBA. Different diagnostic tools, such as CT scan or MRI, are utilized in clinical assessment of the patients, however there is a necessity of further investigation of new diagnostic methods such as biomarkers. A long-term repetitive brain injury can lead in consequence to a Chronic Traumatic Encephalopathy (CTE). Neuroprotection, treatment  and rehabilitation play a crucial role in both prevention and recovery of TBI patients.

Introduction and objective
Osteoporosis is a disorder that leads to a decrease in bone mass, accompanied by a disruption in bone structure, resulting in an increased risk of bone fractures. It affects a large number of people worldwide and constitutes a significant social and economic problem. It primarily affects older individuals, especially postmenopausal women. Fractures associated with osteoporosis diminish the quality of life. Osteoporosis often remains asymptomatic and is difficult to diagnose, typically identified incidentally following a low-energy fracture. Diagnosis of osteoporosis involves measuring bone mineral density using dual-energy X-ray absorptiometry (DEXA). Osteoporosis is diagnosed when bone mineral density is found to be more than 2.5 standard deviations (SD) below the mean bone mineral density of healthy young adults with peak bone mass. Modifiable risk factors for osteoporosis include lack of physical activity, calcium deficiency in the diet, and alcohol consumption.
Review methods
The article was based on scientific papers retrieved from the PubMed website and scientific literature. The focus was on papers from 2016 to 2024. Articles written in English were utilized.
Brief description of the state of knowledge
Physical activity encompasses any muscular movement that increases energy expenditure beyond the resting metabolic rate, including weight-bearing exercises, strength training, high-intensity strength exercises, and balance and mobility training. Weight-bearing exercises yield the best results in osteoporosis prevention, recommended to be performed three times a week.
Summary
Physical activity is a scientifically proven preventive factor against osteoporosis, reducing the frequency of falls and increasing bone mineral density. Initiating physical activity at a young age yields significant benefits for bone strength.

Obesity is a chronic disease that requires diagnosis and treatment. Excess body fat and metabolic disorders, resulting from the disease, are associated with the risk of numerous complications. Among the most widespread are type 2 diabetes, hypertension, dyslipidemia, atherosclerosis, non-alcoholic fatty liver disease and sleep apnea syndrome. Weight reduction significantly improves prognosis, and can mitigate or even reverse complications. A dietary method gaining popularity recently is intermittent fasting. It involves alternating periods of eating and fasting according to a fixed time schedule. There are different types of diet, differing in the length of the fasting period. Intermittent fasting affects the human body by regulating the diurnal rhythm, inducing metabolic switching, that is switching from using glucose as an energy source to lipid oxidation, and by modulating the composition of the gut microbiota. The effects of the diet, proven in clinical trials, include weight loss, improved glucose tolerance, lowered hemoglobin A1c and insulin levels, and improved tissue sensitivity to insulin. However, there is no evidence supporting the superiority of intermittent fasting over continuous calorie restriction. Intermittent fasting also carries a risk of adverse effects, the most serious of which are hypoglycemic episodes. These occur especially in people with type 2 diabetes and taking diabetes medications. 
Although intermittent fasting appears to be a promising strategy in the fight against obesity and type 2 diabetes, further research is needed to evaluate its long-term effects on the human body.

Post-Traumatic Epilepsy (PTE) is a neurological disorder characterized by recurrent seizures that occur as a result of traumatic brain injury (TBI). It represents a significant medical challenge due to its complex pathophysiology, diverse clinical manifestations, and the long latency period between the initial injury and the onset of epilepsy. It typically manifests weeks, months, or even years after the initial trauma, complicating the prognosis and management of head injury patients.  The incidence of PTE varies widely, influenced by the severity and nature of the brain trauma, with higher risks associated with penetrating injuries, severe brain contusions, and hemorrhagic lesions. Pathogenetic mechanisms involve a cascade of molecular and cellular events, including neuroinflammation, blood-brain barrier disruption, and neuronal hyperexcitability, which contribute to the formation of epileptic networks. Diagnosis relies on a detailed patient history, neuroimaging, and electroencephalography (EEG) to confirm seizure activity and exclude other causes. It is often delayed and complicates early intervention strategies. Current management primarily focuses on seizure control through antiepileptic drugs (AEDs), but response rates are variable, and many patients suffer from drug-resistant epilepsy. Advances in neuroimaging and biomarker research hold promise for earlier detection and targeted therapies. This review synthesizes recent findings on the epidemiology, pathophysiology, diagnosis, and management of PTE, highlighting the need for a multidisciplinary approach to improve outcomes for individuals affected by this condition.
