Retention device

(Kosyreva T.F., Vasilyeva M.B., Voeikova O.V.)

The claimed utility model relates to medicine, directly to dentistry and orthodontics, and concerns the design of the retention device. The retention device consists of: a base 1 shortened from the roof of the mouth from photopolymer plastic and two rows of a reinforcing polymer filament 2 with a diameter of 0.35 mm, extending from the vestibular side, then continuing in the base of the device and covered with a photopolymer plastic in the cheek-b side of the crowns teeth 3 without overlapping their cutting edges and occlusal surfaces. The retention device provides an improvement in the result of the retention period after correction of various anomalies of the dentition and anomalies of the teeth.

Unfounded generalizations and false conclusions: RUDN scientists have identified AI “hallucinations” in the diagnosis of mental disorders

Researchers from the Faculty of Artificial Intelligence at RUDN University conducted a large-scale study that revealed systemic errors in large language models (LLMs) when diagnosing depression based on text. This work, carried out in collaboration with colleagues from AIRI, Federal Research Center “Computer Science and Control” of the Russian Academy of Sciences, Ivannikov Institute for System Programming of the Russian Academy of Sciences, Moscow Institute of Physics and Technology, and MBZUAI, not only identifies the problem but also lays the foundation for the creation of more reliable and secure tools for detecting depression and anxiety.
