    Rojas-Solorzano, L.; Saliev, T.; Adair, D.; Finol, E. (Nazarbayev University, 2013)
    Cardiovascular Disease (CVD) leads to the major number of deaths in the USA and Europe (European Heart Network, 2008; US National Center for Health Statistics, 2012). In Kazakhstan, CVD represents also the first cause of ...
  • Hemofiltration-induced neuroprotection following ischemic stroke 
    Zhumadilov, A.; Zlotnik, A.; Gilman, C.; Viderman, D.; Umbetzhanov, Y.; Smagulova, B.; Korabaev, G.; Zhumabaev, M.; Asselbekov, Zh.; Esenalin, N. (Nazarbayev University, 2013)
    Ischemic stroke is accompanied by a three to four hundred percent increase in the brain’s extracellular fluid and cerebrospinal fluid glutamate concentration, which diffuses and damages surrounding neurons. In preclinical ...
  • HLA-binding peptide affinity prediction and T cell-mediated response 
    Schönbach, C.; Su, C.; Kwoh, C-K. (Nazarbayev University, 2013)
    In a future pandemic it is therefore expected that apart from a few mutated epitopes, heterologous immunity mediated by pre-existing cross-reactive T cell responses to seasonal influenza virus will ameliorate its severity ...
  • Laser thermoelastic generation in metals above melt threshold 
    Every, A.G.; Utegulov, Z.N.; Veres, I.A. (Nazarbayev University, 2013)
    We have established the detailed spatio-temporal evolution of heat conduction of the irradiated sample due to the incidence of a laser pulse, including the temperature rise of the solid phase preceding the melting, and the ...
  • Localized detection of phase transition in tungsten by laser ultrasonics 
    Utegulov, Z.N.; Reese, S.J.; Farzbod, F.; Schley, R.S.; Hurley, D.H. (Nazarbayev University, 2013)
    We demonstrated a method for localized, furnace-free detection of the onsets of melting and ablation in polycrystalline tungsten using nanosecond laser ultrasonics. Pulsed laserinduced melting is characterized by a delay ...
