Development of a multi-payload 2U CubeSat: the Alba project

Alba CubeSat UniPD is a student team of University of Padova with the aim to participate to the ESA Fly Your Satellite! (FYS!) programme and to launch for the first time at University of Padova a CubeSat made by students. The proposed mission has three independent objectives: (1) to collect in-situ measurements of the sub-mm space debris environment in LEO, (2) to study the micro-vibration environment on the satellite throughout different mission phases, (3) to do precise orbit determination through laser ranging and evaluate procedures for fast satellite Pointing, Acquisition and Tracking (PAT) from ground. The proposed technological experiments aim to obtain data that will enrich the current knowledge of the space environment and will provide precious information useful for the further development of some research projects currently performed at University of Padova. In order to reach the objectives, in these years the activities of the teams aimed to develop a 2U CubeSat equipped with three payloads. The first payload is an impact sensor that will be placed on one of the outer faces of the satellite and will be able to count the number of debris impacting the spacecraft thus being able to measure the energy/momentum transferred to the satellite. The second one is a Commercial Off The Shelf (COTS) sensor that measures the micro-vibrations experienced by payloads in a CubeSat in different mission phases. The third one consists in a number of COTS Corner Cube Retroreflectors that will be placed onboard the satellite. Thanks to this, Satellite Laser Ranging (SLR) will be done to collect data on the satellite range and range rate using a facility currently under development at University. This paper presents the mission objectives and motivations. In addition, the mission phases and the preliminary design of the CubeSat reached during the activities of the project are shown. Particular attention is given to the payloads which are the most challenging aspect of this project

Wellens Syndrome: Single Centre Study and Literature Review

Wellens syndrome is a clinical, biological, and electrocardiographic complex that identifies a subgroup of patients with unstable angina who have an impending risk of myocardial infarction and death, representing an equivalent of ST segment elevation myocardial infarction

TA-DA: Topic-Aware Domain Adaptation for Scientific Keyphrase Identification and Classification (Student Abstract)

Keyphrase identification and classification is a Natural Language Processing and Information Retrieval task that involves extracting relevant groups of words from a given text related to the main topic. In this work, we focus on extracting keyphrases from scientific documents. We introduce TA-DA, a Topic-Aware Domain Adaptation framework for keyphrase extraction that integrates Multi-Task Learning with Adversarial Training and Domain Adaptation. Our approach improves performance over baseline models by up to 5% in the exact match of the F1-score

THE FUTURE OF ENDODONTICS. A SYSTEMATIC REVIEW

Aim of the study The main objective of this paper is to perform an updated literature review of future endodontics trends based on the available up-to-date scientific literature to identify and describe the new techniques, new materials and their benefits or their limitations. Material and methods Electronic databases (PubMed, Wiley Online Library, Google Scholar and Web of Science) were used to perform a literature search from 2018 to 2023 using MESH terms: Endodontics, Artificial Intelligence, Lasers. After discarding duplicates, out of 1283 results, a total of 18 articles were eligible and point out how endodontic protocol may change with the onset of new technologies and procedures. Results Nanoparticle, laser, regenerative treatment, guided endodontics and artificial intelligence are the main areas that shown promising results in endodontic treatment. New materials with biological capacities will improve the long-term results. Overall, endodontic treatment tends to became more precise and the complications can be reduced. Conclusions Endodontics will see many exciting developments over the coming years, some incremental, others paradigm shifting
