From February 14 to 18, the LIMU team took an active part in the XXXIV session of the Russian Acoustical Society held in a hybrid in-person/virtual format at the N.N. Andreyev Acoustics Institute (Moscow, Russia). Overall, LIMU presented 17 talks in the sections devoted to "Nonlinear acoustics", "Ultrasonic technologies", "Bioacoustics and medical applications of acoustical methods" and "Physical acoustics". Most of our students and postgraduates were awarded diplomas for the best reports of young specialists!

Ph.D. student of LIMU Dmitry Nikolaev has successfully defended his PhD thesis on December 30, 2021. The thesis was prepared under supervision of Dr. Sergey Tsysar. Congratulations to Dr. Nikolaev!

The top-rated journal The Journal of the Acoustic Society of America (Q1) published an article presenting a new method for measuring the acoustic characteristics of materials at megahertz frequencies, as well as its experimental verification. The proposed method is based on the use of transient acoustic holography technique.

Results of a joint study of LIMU, MREC MSU and Dmitry Rogachev National Research Center were published in a top-rated Ultrasound in Medicine and Biology journal. The study was devoted to non-invasive liquefaction of volumetric human hematomas using focused ultrasound pulses with shock fronts.

The autumn semester ended with joyful events for LIMU. D. Nikolaev and S. Petrosyan received postgraduate diplomas. Postgraduate student A. Krokhmal won the coursework competition in the framework of teaching the use of neural networks in scientific research. 2nd year students of magistracy P. Pestova and L. Kotelnikova received scholarships from the Basis Foundation. And LIMU employees won the competition for works contributing to the solution of the tasks of the Development Program of Moscow University.

Scientific project of LIMU research fellow Timofey Krit «Mechanical elasticity of tissue-like materials for tissue engineering» is supported by a grant from the Russian Science Foundation. Congratulations to Timofey!

V.A. Khokhlova presented a lecture on "Nonlinear HIFU: Modeling, Sources, and Bioeffects" at October 28, 2021 webinar of the International Society for Therapeutic Ultrasound (ISTU). The lecture covered various aspects of nonlinear effects in HIFU, from basic wave phenomena to current clinical applications.

October 15, 2021, at the invitation of the organizers of the physics section of the Central House of Scientists, Professor O.A. Sapozhnikov gave a lecture on the topic "Modern problems of medical acoustics", in which he spoke about the current state of research in the field of medical ultrasound imaging and therapy.

In September 2021, a special issue of IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control was published devoted to histotripsy. One of the organizers and editors of the issue was V.A. Khokhlova; 4 articles were co-authored with LIMU team.

LIMU members Petr V. Yuldashev, Maria M. Karzova, Timofey B. Krit and Anastasia V. Lapina passed through the faculty competition for new positions. Congratulations and wish them further career success!

The bank of LIMU's achievements is growing. Azamat Kaloev and Ksenia Tumanova received FUSF grants for scientific research during the summer of 2021. Ksenia won a prize in the competition of scientific student graduation works named after R.V. Khokhlova. Postgraduate student Dmitry Nikolaev received the ASA-2021 student award of the American Acoustic Society for success in scientific work, his project became the winner of the UMNIK competition. Alisa Krokhmal, a postgraduate student, received a scholarship from the Intellect Foundation for teaching the use of neural networks in scientific research.
