Earthquakes Can Be Predicted Five Days Ahead
An international team of researchers, which includes physicists from HSE University and the RAS Space Research Institute (IKI), have discovered that, with an impending earthquake, the parameters of internal gravity waves (IGWs) can change five days before a seismic event. This data can help experts develop short-term earthquake forecast methods. The results of the study have been published in the journal Doklady Earth Sciences.

HSE Joins the Russian-African Cooperation Agenda
HSE University, together with the Russian foreign economy research centre Integratsiya Ekspertizy (Expertise Integration), will create a Centre for African Studies. The Centre will be based at the HSE Faculty of World Economy and International Affairs and will be a leading analytical platform in support of Russian-African relations. The founding of the Centre will be announced at the Russia-Africa Economic Forum, which begins in Sochi on October 23.

The shape of time-of-flight curves in the mode of subsurface irradiation of samples with lowenergy electrons is analyzed for free_standing films of a typical molecularly doped polymer of different thicknesses (11–45 μm). Special attention is paid to comparison of curves registered for both sides of the samples. The data confirm the hypothesis that the defective layer is formed owing to sublimation of dopant molecules during sample preparation and qualitatively agree with predictions of the two_layer multiple_trapping model.

Hole Transport in Bisphenol‑A Polycarbonate Doped with N,N′‑Diphenyl‑N,N′‑bis(3-methylphenyl)-[1,1′-biphenyl]-4,4′-diamine
Weiss D. S., Andrey P. Tyutnev, Evgenii D. Pozhidaev. Journal of Physical Chemistry. 2015. Vol. 119. No. 3. P. 5334-5340.

ABSTRACT: The time-of-flight (TOF) transients of solution-cast, free-standing films of N,N′-diphenyl-N,N-bis(3-methylphenyl)-[1,1′-biphenyl]-4,4′diamine (TPD) in bisphenol A polycarbonate (PC) have been studied using electron gun induced charge generation. This molecularly doped polymer (MDP) has been shown to exhibit perfectly flat plateaus on its time-of-flight curves with optical excitation. Our TOF results with continuously changing electron energies, as well as numerical calculations using a multiple trapping model with a Gaussian trap distribution (MTMg), suggest that charge carrier transport in this molecularly doped polymer is nonequilibrium and the flat plateaus can be explained by the presence of a thin surface layer depleted of transport material. The depleted surface layers on samples of this molecularly doped polymer are extremely thin (less than 0.12 μm), with those relating to the release side (contacting a substrate during coating/drying procedure) being much smaller than for the free side exposed to air. Since TPD-doped PC and a tetraphenylbenzidine polymer containing the TPD moiety in its main chain served as the prototype materials for the concept of “trap-free” carrier transport, we have also discussed this in detail.
