Design, production and characterization of mirrors for ultra-broadband, high-finesse enhancement cavities

To enable the enhancement of few-cycle pulses in high-finesse passive optical resonators, a novel complementary-phase approach is considered for the resonator mirrors. The design challenges and first experimental results are presented.Comment: 3 page

Online education in medical university during COVID-19 Pandemic

Due to the development and widespread of the COVID-19 pandemic around the world, and the need to continue the educational process at both undergraduate and postgraduate levels, many universities and other educational institutions have undergone changes in the educational process [1, 2]. Thus, the Odessa National Medical University at the cycle of Simulation Medicine has developed and implemented online educational programs for 6th year students and interns with the use of Microsoft Teams [3]. It should be noted that one of the main missions of the cycle is training aimed at identifying and assessing the acquisition of clinical skills by students [4, 5] and their acquisition of professional competencies - for the successful completion of OSCE (Objective Structured Clinical Exam)

Effects of cerebellar transcranial direct current stimulation upon kindled seizures depends upon PPARγ modulation

The purpose of the investigation was to estimate the effectiveness of peroxisomal proliferator-activated γ-receptors (PPARγ) modulation upon the antiseizure effects of transcranial direct current stimulation (tDCS). In rats with the kindling syndrome was induced by i.p. injections of pentylenetetrazol (PTZ; 30.0 mg/kg daily, for three weeks). For tDCS active electrode was located over cerebellar zone of cranium (10 mm2). The latent period of seizures induced by a test injection of PTZ (30 mg/kg) increased significantly (by 22.5% on average P b .05 vs. control) after tDCS (600 μA, 10.0 min, cathode on the skull surface)
