Three scientists were selected to present the Ta Quang Buu Prize in 2020

The research of three scientists conducted in Vietnam in the fields of medical science, mathematics and physics, has been published in excellent international journals.

The Minister of Science and Technology approved the proposal to award the Ta Quang Buu Prize in 2020 to three scientists with outstanding research based on the proposal of the Award Council. In particular, Assoc.Prof .  Dr. Vuong Thi Ngoc Lan , Ho Chi Minh City University of Medicine and Pharmacy, the field of medicine; Assoc.Prof. Dr. Pham Tien Son , Da Lat University, field of mathematics. Dr. Nguyen Truong Thanh Hieu , Ton Duc Thang University, field of physics.

Associate Professor Vuong Thi Ngoc Lan's research on in vitro fertilization. In the case of women performing in vitro fertilization (IVF) techniques, transfer of frozen embryos is considered to result in a higher pregnancy rate than transfer of fresh embryos in infertility cases with chamber syndrome Polycystic eggs. It is not known whether frozen embryo transfer can produce similar results in infertile women without polycystic syndrome.

The study concluded that, for infertility women without polycystic ovary syndrome, when performing IVF, frozen embryo transfer did not significantly increase the progression rate or survival rate compared to the transfer. fresh embryos.

In the field of mathematics, Assoc.Prof. Dr. Pham Tien Son studied a fundamental problem that is a half-algebra optimal problem: finding the smallest value of a polynomial function over a set of half algebra (is set determined by equations and polynomial inequalities). 

Based on the research results, it is proved that the optimal solution of most polynomial optimization problems is completely determined by solving a finite number of semi-determinate planning problems.

The research of Dr. Nguyen Truong Thanh Hieu shows that the dielectric approach can determine the distance of inelastic free electrons in materials with the same accuracy as calculations from the first principles in approximation. GW slag of multi-particle system theory. The current approach is another option for calculating the lifetime of hot electrons, which is an important quantity in ultrafast electronic dynamics.

The scientists who won the Ta Quang Buu Award this year all work in units of the Central and Southern regions. This is also the second year, a female scientist in the field of Biomedical Pharmacy won the Prize.

The Awards Ceremony is expected to be held on the occasion of Vietnam Science and Technology Day 18/5 in Hanoi.

Three works selected for awards:

1. Assoc.Prof. Dr. Pham Tien Son (Dalat University) with the project "Generic properties for semialgebraic programs" published in SIAM Journal on Optimization.

2. Assoc. Prof. Dr. Vuong Thi Ngoc Lan (HCMC University of Medicine and Pharmacy) with the project "IVF transfer of Fresh or Frozen embryos in women without Polycystic Ovaries" published in The New England Journal of Medicine.

3. TS. Nguyen Truong Thanh Hieu (Ton Duc Thang University) with the project "Low-energy electron inelastic mean free path in materials" published in Applied Physics Letters
