Some historical features of international cooperation that have been a background for originating the idea to organize since 1980 special international meetings named Spring Schools on Acousto-Optics and Applications and for continuing the events until now are presented. Thanks to the establishment of the Spring Schools, the group of acousto-opticians at the Gdańsk University have had the opportunity to exchange scientific experience and continue mutual cooperation in research with several acousto-optic centers and to publish a number of common papers. A few examples from these achievements and some historical facts illustrating research activity in the field of acousto-optics during past 30 years are recollected.

To analyze the motion laws of a magnetic and elastic coupling system under the influence of various factors, this paper proposes a magnetic coupling pendulum based on spring pieces and magnets-a magnetic-mechanical oscillator. By fixing spring pieces onto two non-magnetic bases and attaching magnets to their upper ends, which repel each other, the potential energy during oscillation is expanded using Fourier series. Subsequently, Lagrange equations are solved to study the effects of the first two terms of potential energy.

Background: Hemorrhagic fever with renal syndrome (HFRS) is a climate-sensitive zoonotic disease that poses a significant public health burden worldwide. While previous studies have established associations between meteorological factors and HFRS incidence, there remains a critical knowledge gap regarding the heterogeneity of these effects across diverse epidemic regions. Addressing this gap is essential for developing region-specific prevention and control strategies.

Objective: Bosentan (BOS) is approved for treating pulmonary arterial hypertension (PAH) and preventing digital ulcers (DU) in systemic sclerosis (SSc). Our study aimed to evaluate whether BOS prescribed for DU could reduce the incidence of PAH in a large SSc cohort from the SPRING registry.
Methods: Patients with SSc from the SPRING registry, meeting ACR/EULAR 2013 classification criteria with data on PAH onset, DU status, BOS exposure, and at least a one-year follow-up between 2015 and 2020, and no known PAH at baseline were included.
Aim: Romania is currently facing a prolonged measles outbreak. The aim of the study was to analyse the circulating human measles virus (HMV) strains by combining whole genome sequencing (WGS) with phylogenetic analysis, with a focus on the haemagglutinin gene.
Methods: We conducted an observational study in the first five months of 2024, in which 168 patients diagnosed with measles were randomly included.

In the production sector, the usefulness of predictive systems as a tool for management and decision-making is well known. In the agricultural sector, a correct economic balance of the farm depends on making the right decisions. For this purpose, having information in advance on crop yields is an extraordinary help.
