Investigating the impact of fuel price shocks on bicycle sharing usage in Budapest.

The creation of sustainable urban communities is contingent upon the establishment of a sustainable, efficient, and fast transportation system. Bicycle sharing systems (BSS) are one of the most sustainable and inclusive ways of transportation in cities. An important question is how to increase BSS ridership and whether it can effectively replace cars in cities, hence contributing to achieving the 11th Sustainable Development Goal and creating sustainable urban communities.

Unmasking Risky Habits: Identifying and Predicting Problem Gamblers Through Machine Learning Techniques.

The use of machine learning techniques to identify problem gamblers has been widely established. However, existing methods often rely on self-reported labeling, such as temporary self-exclusion or account closure. In this study, we propose a novel approach that combines two documented methods.

[Thyrotropin-secreting pituitary adenomas--diagnosis and treatment in five case].

The authors report five cases of thyrotropin secreting pituitary adenomas (4 males and 1 female) in whom the diagnosis was established by a combined occurrence of elevated serum free thyroid hormone levels and measurable serum thyrotropin concentration, as well as by visualisation of the pituitary adenomas using magnetic resonance imaging (pituitary microadenoma in two and macroadenoma in three cases). Other tests were less diagnostic: only two out of 4 patients proved to be non-responders during testing with thyrotropin releasing hormone, and serum alpha subunit was elevated in only 2 out of 3 cases. There was a significant decrease of serum thyrotropin concentration in all of the four patients tested by 100 micrograms octreotide (Sandostatin, Novartis).
