ARIES 2018 : infrastructure, innovation, outreach
This article has two outreach aims. It concisely summarizes the main research and technical efforts in the EC H2020 ARIES Integrating Activity – Accelerator Research and Innovation for European Science and Society [1] during the period 2017/2018. ARIES is a continuation of CARE, TIARA and EuCARD projects [2-3]. The article also tries to show these results as an encouragement for local physics and engineering, research and technical communities to participate actively in such important European projects. According to the author’s opinion this participation may be much bigger [4-27]. All the needed components to participate – human, material and infrastructural are there [4,7]. So why the results are not satisfying as they should be? The major research subjects of ARIES are: new methods of particles acceleration including laser, plasma and particle beam interactions, new materials and accelerator components, building new generations of accelerators, energy efficiency and management of large accelerator systems, innovative superconducting magnets, high field and ultra-high gradient magnets, cost lowering, system miniaturization, promotion of innovation originating from accelerator research, industrial applications, and societal implications. Two institutions from Poland participate in ARIES – these are Warsaw University of Technology and Institute of Nuclear Chemistry and Technology in Warsaw. There are not present some of the key institutes active in accelerator technology in Poland. Let this article be a small contribution why Poland, a country of such big research potential, contributes so modestly to the European accelerator infrastructural projects? The article bases on public and internal documents of ARIES project, including the EU Grant Agreement and P1 report. The views presented in the paper are only by the author and not necessarily by the ARIES
Perspectives and Challenges of Decentralized Identities in the Blockchain era
openIl presente documento descrive il lavoro svolto durante il periodo di stage, della durata di circa 276 ore, dal laureando Nicola Lazzarin presso l’azienda Athesys s.r.l, con periodo dal 06/07/2023 al 23/07/2023.
Il paradigma delle identità digitali è fondamentale nell’era digitale, ma spesso sottolinea l’inefficienza dei tradizionali sistemi centralizzati.
L’emergere delle Self-sovereign identity (SSI) offre un nuovo approccio promettente per migliorare la gestione delle identità digitali e delle Verifiable Credentials (VC).
Tuttavia, l’attuazione pratica di soluzioni basate su SSI, in particolare utilizzando il framework Hyperledger Aries, rimane una sfida complessa e impegnativa.
La presente tesi trae ispirazione dalla rilevanza delle identità digitali nella società odierna e dalla crescente necessità di soluzioni SSI.
Tuttavia, essa si concentra su una prospettiva critica basata sull’esperienza personale dell’autore, che, nonostante gli sforzi, non è riuscito a pieno a completare l’implementazione di un sistema di scambio di VC utilizzando il framework Hyperledger Aries JavaScript.
Il principale contributo di questa tesi è rappresentato dalla realizzazione parziale di un Proof of Concept (PoC) per un sistema di scambio di VC basato sul framework Hyperledger Aries JavaScript.
Questo PoC offre una base incompleta per ulteriori sviluppi nel campo delle SSI. Inoltre, questa ricerca fornisce una documentazione dettagliata sul processo di implementazione, comprese le scelte di progettazione e le tecnologie utilizzate, per agevolare ulteriori studi e implementazioni nel settore delle identità digitali decentralizzate.
In conclusione, questo tirocinio ha fornito un’opportunità di apprendimento e applicazione pratica di concetti avanzati nel campo delle identità digitali e delle credenziali verificabili.This paper describes the work done during the internship period, lasting about 276 hours, by graduate student Nicola Lazzarin at the company Athesys s.r.l, with a period from 06/07/2023 to 23/07/2023.
The paradigm of digital identities is crucial in the digital age, but often underscores the inefficiency of traditional centralized systems.
The emergence of Self-sovereign identities (SSI) offers a promising new approach to improve the management of digital identities and Verifiable Credentials (VC).
However, the practical implementation of SSI-based solutions, particularly using the Hyperledger Aries framework, remains a complex and demanding challenge.
This thesis draws inspiration from the relevance of digital identities in today's society and the growing need for SSI solutions.
However, it focuses on a critical perspective based on the personal experience of the author, who, despite his efforts, was not fully successful in completing the implementation of a VC exchange system using the Hyperledger Aries JavaScript framework.
The main contribution of this thesis is the partial implementation of a Proof of Concept (PoC) for a VC exchange system based on the Hyperledger Aries JavaScript framework.
This PoC provides an incomplete basis for further development in the field of SSI. In addition, this research provides detailed documentation of the implementation process, including design choices and technologies used, to facilitate further studies and implementations in the area of decentralized digital identities.
In conclusion, this internship provided an opportunity for learning and practical application of advanced concepts in the field of digital identities and verifiable credentials
I.FAST and EURO-LABS Perfect Legacy of ARIES
CERN hosted on May 2-6, 2022, the first annual meeting of the H2020 I.FAST project to support innovation in the field of science and technology of particle accelerators. The project has a completely different character from its predecessors in this area of research. It was approved for implementation a year ago by the EC with the highest marks. It is worth looking at why projects such as ARIES, I.FAST and EURO-LABS are so easily accepted. This alleged ease of acceptance is an appearance. Behind the acceptance, in conditions of extremely tough competition, is the excellent organization of the submitting community that has been developed over the years, as well as the perfect, well-thought-out preparation of the material. The author, a participant in the ARIES and other EC projects in the field of particle accelerator science and technology, presents here, on specific examples, his subjective opinions on how to prepare materials for high-output projects for the EC FP. The author hopes that these remarks may be useful in the process of submitting research projects from Poland in international cooperation to the EC in the best possible way. The science and technology of particle accelerators is an excellent area of showing such examples because it is interdisciplinary and includes the following components: building of research infrastructure, applied physics, mechatronics, materials engineering, automation and robotics, electronics, ICT, innovation, cooperation with industry, and social
SIMULATION-BASED LEARNING IN RELIGIOUS EDUCATION TO DEVELOP STUDENT EMPATHY ON PEACE EDUCATION
SIMULATION-BASED LEARNING IN RELIGIOUS EDUCATION TO DEVELOP STUDENT EMPATHY ON PEACE EDUCATION Aries Musnandar
Abstract This study proposes an effective learning model to increase the quality of students’ empathy through simulation-based learning. The student’s noble behaviour as the objective religious subject in schools can be reached by fostering empathy. But, conservative teaching techniques such as lecturing, presentation and one-way communication are used by most teachers. In contrast, the simulation based-learning model for religious education could involve the affective domain which is appropriate to be used for behaviour change. Peace education in religious education subjects can be elaborated proportionally using simulation based-learning for developing the empathy of student as an important factor to have better peace education results. By using qualitative method, author conducted interview, observation and literature review for further analysis of this study. Research results confirmed that teacher who apply simulation based learning as a suitable method to enhance empathy for elevated tolerant behavior of students which is in line with peace education view. Keywords: Simulation-Based Learning, Empathy, Peace Education, Religious Education

From ARIES to MARS: Transaction Support for Next-Generation, Solid-State Drives
Transaction-based systems often rely on write-ahead log-ging (WAL) algorithms designed to maximize perfor-mance on disk-based storage. However, emerging fast, byte-addressable, non-volatile memory (NVM) technolo-gies (e.g., phase-change memories, spin-transfer torque MRAMs, and the memristor) present very different perfor-mance characteristics, so blithely applying existing algo-rithms can lead to disappointing performance. This paper presents a novel storage primitive, called editable atomic writes (EAW), that enables sophisticated, highly-optimized WAL schemes in fast NVM-based stor-age systems. EAWs allow applications to safely access and modify log contents rather than treating the log as an append-only, write-only data structure, and we demonstrate that this can make implementating complex transactions simpler and more efficient. We use EAWs to build MARS, a WAL scheme that provides the same as features ARIES [26] (a widely-used WAL system for databases) but avoids mak-ing disk-centric implementation decisions. We have implemented EAWs and MARS in a next-generation SSD to demonstrate that the overhead of EAWs is minimal compared to normal writes, and that they pro-vide large speedups for transactional updates to hash tables, B+trees, and large graphs. In addition, MARS outperforms ARIES by up to 3.7 × while reducing software complexity. ∗Now working at Google Inc.

High-frequency vertical profiling of meteorological parameters using AMF1 facility during RAWEX-GVAX at ARIES, Nainital
An extensive field study, RAWEX-GVAX, was carried out during a 10-month (June 2011-March 2012) campaign at ARIES, Nainital and observations on a wide range of parameters like physical and optical properties of aerosols, meteorological parameters and boundary layer evolution were made. This work presents results obtained from high-frequency (four launches per day), balloon-borne observations of meteorological parameters (pressure, temperature, relative humidity, wind speed and wind direction). These observations show wind speed as high as 84 m/s near the subtropical jet. It is shown that reanalysis wind speeds are in better agreement at 250 hPa (altitude of subtropical jet) than those above or below this value (100 hPa or 500 hPa). These observations also demonstrate that AIRS-derived temperature profiles are negatively biased in the lower altitude region, whereas they are positively biased near the tropopause. WRF simulated results are able to capture variations in temperature, humidity and wind speed profile reasonable well. WRF and AIRS-derived tropopause height, tropopause pressure and tropopause temperature also show agreement with radiosonde estimates
Do sheep (<i>Ovis aries</i>) discriminate human emotional odors?
Corresponding author: [email protected] audienceWhile sheep can detect and discriminate human emotions through visual and vocal cues, their reaction to human body odors remains unknown. The present study aimed to determine whether sheep ( Ovis aries ) can detect human odors, olfactorily discriminate stressed from non-stressed individuals, and behave accordingly based on the emotional valence of the odors. Axillary secretions from 34 students were collected following an oral examination (stress odor) or a regular class (non-stress odor). Fourteen female and 15 male lambs were then exposed to these odors through a habituation-dishabituation procedure. The habituation stimulus was presented four times for one minute, followed by the dishabituation stimulus presented once for one minute. Behavioral variables included spatiality relative to target odors, approach/withdrawal, ear positioning, sniffing, ingestion, and vocalization. Both female and male lambs more often positioned their ears backwards/forwards, and asymmetrically when exposed to the dishabituation stimulus, but regardless of their stress or non-stress value. They also changed their approach behavior when exposed to the dishabituation stimuli. Lambs displayed some behavioral signs of discrimination between the habituation and dishabituation odors, but regardless of their relation to stress or non-stress of human donors. In sum, this exploratory study suggests that young sheep respond negatively to the odor of unfamiliar humans, without showing any specific emotional contagion related to the stress odor. This exploratory study suggests young ovines can detect human body odor, a further step toward understanding the human-sheep relationship
Incisor Disorders of Merino Sheep (<em>Ovis aries</em>)
\ua9 The Author(s) 2025. This study documents dental anomalies in 2414 Merino ewe sheep (Ovis aries) from 7 Australian Merino Sire Evaluation Association sites observed during routine husbandry. Teeth were photographed and evaluated using visual scoring protocols to assess plaque accumulation, enamel wear, and other anomalies across all incisors. Plaque scoring revealed a median plaque score of 3 (IQR \ub1 1) on buccal surfaces and 2 (IQR \ub1 2) on lingual surfaces, indicating substantial plaque accumulation across incisors. Two cases of geminated incisors and one case of fused central incisors were identified, representing the first documented cases in sheep and expanding existing knowledge of dental anomalies in sheep. Dental wear assessments showed that 13% of 10-month-old ewes and 33% of 20-month-old ewes had significant enamel loss or pulp exposure, with an average of 2 teeth per affected ewe displaying pulp necrosis. Amelogenesis imperfecta was recorded in 5% of the younger and 37% of the older groups. Missing incisors, suggesting early dentition changeover, were observed in 9% of 20-month-old sheep. Localized enamel hypoplasia, potentially resulting from trauma or disruptions during enamel development, was noted in 1% of both age groups. Dental caries was identified in five 20-month-old ewes with permanent incisors. These findings provide a comprehensive overview of the range and prevalence of dental conditions in Merino sheep, including common wear patterns and rare anomalies. Documenting such conditions in sheep contributes valuable information to veterinary dentistry, highlighting the need for further research into incisor health in sheep
