GROWTH HORMONE’S INTRACELLULAR SIGNALING: CURRENT VIEW, PHYSIOLOGICAL EFFECTS, FORWARDLOOKING ASSESSEMENT

Publikováno v: Вісник проблем біології і медицини, Iss 1, Pp 39--3 (2022)

The growth hormone (GH), although most well known for regulating linear growth, has a great number of another important biological functions like controlling physiological processes related to the cardiovascular, hepatobiliary, renal, gastrointestina

Report

Interlayer excitons in semiconductor bilayers under a strong electric field

Autor: Kovalchuk, S., Greben, K., Kumar, A., Pessel, S., Watanabe, K., Taniguchi, T., Christiansen, D., Selig, M., Knorr, A., Bolotin, K. I.

Excitons in bilayer transition metal dichalcogenides (2L-TMDs) are Coulomb-bound electron/hole pairs that can be viewed as broadly tunable analogs of atomic or molecular systems. Here, we study the properties of 2L-TMD excitons under strong electric

Report

Demonstrating a single-block 3D-segmented plastic-scintillator detector

Autor: Boyarintsev, A., De Roeck, A., Dolan, S., Gendotti, A., Grynyov, B., Kose, U., Kovalchuk, S., Nepokupnaya, T., Rubbia, A., Sgalaberna, D., Sibilieva, T., Zhao, X. Y.

Three-dimensional finely grained plastic scintillator detectors bring many advantages in particle detectors, allowing a massive active target which enables a high-precision tracking of interaction products, excellent calorimetry and a sub-nanosecond

Report

Extrinsic localized excitons in patterned 2D semiconductors

Autor: Yagodkin, D, Greben, K, Eljarrat, A, Kovalchuk, S, Ghorbani-Asl, M, Jain, M, Kretschmer, S, Severin, N, Rabe, J P, Krasheninnikov, A V, Koch, C T, Bolotin, K I

We demonstrate a new localized excitonic state in patterned monolayer 2D semiconductors. This state is not associated with lattice disorder but is extrinsic, i.e. results from external molecules on the material surface. The signature of an exciton as
