One most efficient gain media in solid-state lasers is the crystal YAG doped with Nd. But fabricating an Nd:YAG optical fiber has proven to be particularly challenging because of thermal expansion and diffusion. The aim of this study was to fabricate an Nd:YAG silica fiber with a majority content of YAG in the fiber’s core to subsequently utilize the fiber …
Antibodies targeting transient receptor potential vanilloid 1 as potential drug candidates for the treatment of chronic pain
Chronic pain is a major global health problem. The drugs that are currently used to treat the condition have limitations, such as side effects and insufficient pain relief. Therefore, research is underway to develop therapeutic antibodies that can target pain receptors. One receptor that has been of great interest for its involvement in chronic pain is transient receptor potential vanilloid …
The Aluminium Complex’s Ability to Bind Phosphorus in Acidic Conditions
Eutrophication poses threats to aquatic ecosystems, necessitating effective mitigation methods. This study has evaluated the efficacy of aluminium treatment in reducing eutrophication under acidic conditions in various water bodies using spectrophotometry and gravimetry. Results indicate a correlation between increased precipitation mass and reduced orthophosphate levels at higher pH. This correlation is due to pH-dependent equilibrium reactions. Acidification below pH 5.7 …
Is it appropriate to talk about ‘Reconquista’ in the History of Spain? Answer through dialogic analysis
The suitability of the term ‘Reconquista’ (Reconquest) represents an urgent problem in Spanish society due to its questioned political use, its potential ideological charge, its ambiguous official definition and its potential oversimplification. From the innovative methodology of dialogical analysis, four novel theses on the term ‘Reconquista’ are constructed to better understand this phenomenon: ‘Reconquista’ as an operational term, ‘Reconquista’ as …
Bioethics and Protection of Human Dignity in Research and Healthcare
The aim of this project is to study the degree of knowledge and awareness of the bioethical guidelines established at International, European and National level that seek to protect human dignity. Thus, in the first place, it carries out a historical review about some of the events that led to the creation of bioethical norms as well as a review …
No more Itaewon crowd crush disaster: Safety in dense crowds transformed by ‘KOSMOS’ service with AI reinforcement learning
“The 2022 Itaewon crushing incident raised public safety concerns. In response, we developed KOSMOS, an AI service addressing “”crowd turbulence””. It employs a reinforcement learning-based AI, designed to suggest routes for crowd dispersion and collision minimization. Our model’s effectiveness in suggesting safe, efficient routes was verified through a simulation that recreated the Itaewon incident using Seoul’s road data. The KOSMOS …
Protect Art and Creativity: A Prevention Framework for Unauthorized Learning of Text to Image AIs.
In this work, we aim to solve the problem of unauthorized learning of works arising from mass data collection from Text to Image AI models, specifically Stable Diffusion. The TTI model performs indiscriminate web data crawling to collect images, and these images are used for model learning without the consent of the author. The TTI model is capable of learning …
Calculation of the expansion rate of the universe, the density of dark energy in it and the study of the Hubble Tension, which is among the most important unsolved problems in today’s cosmology
A known disagreement in today’s cosmology concerns the universe’s expansion rate – the “Hubble Tension”, which arises due to different measurement methods leading to different results. In this study, the values of Hubble’s constant (the universe’s expansion rate), the dark energy and mass density in the universe are calculated. An LSQ algorithm fitted redshift and distance data of 1a supernovae …
Assessing the Impact of Second-Level Education on Key Aspects of Adolescents’ Life and Development’
This project is a multiyear study undertaken over 3 years (’20, ’21, ’22), encompassing the opinions of over 2,500 students and 220 teachers on the impact of secondary school on students’ social development, physical health and mental wellbeing and outlining possible improvements to the education system. Also considered was the impact of COVID-19 on the mentioned areas and also Online …
Gaming Accessibility, 3D printed adaptive gaming controller accessory for individuals with disabilities
Background: Cerebral palsy (CP) is the most common (3:1000) childhood movement disorder. Gaming can help integrate individuals with disabilities into a community, but those with CP struggle with gaming due to limited hand function and fine motor coordination. Objectives: To develop an affordable and personalizable adaptive gaming controller add-on for individuals with CP to play online games and connect with …
