Earth crust faults dynamics:
Fault dynamics is one of the most
complicated (yet very significant from a practical point of view) geophysical problem,
requiring multiple approaches for a sufficient description. I'm developing a
model allowing a unified analytical treatment of various
seismic events, such as regular earthquakes, slow seismic events and creep [Gershenzon et al, 2009(a); Gershenzon
& Bambakidis, 2011] and slow slip events [Gershenzon
et al, 2011; Gershenzon & Bambakidis, 2012]
Nonlinear
integrable equations:
For over a century a
paramount task of traditional mathematical physics has been the solution of
three linear partial differential equations: the wave equation, the heat
conduction equation, and Laplace’s equation. Their importance is due to their
exceptional universality. In the last few decades, this list of fundamental
equations has been enriched by some essentially nonlinear equations, such as
Korteweg-de Vries, nonlinear Schrodinger, and the sine-Gordon equations. These
equations have much in common. In particular, they have special solutions
(solitons) which are localized in time and space and are similar to classical
particles. These so-called integrable nonlinear equations are also
exceptionally universal. I have obtained results applying the sine-Gordon
equation to seemingly unrelated objects and processes such as dislocation
motion in crystals [Gershenzon, 1994a], laser beam propagation through
two-level systems [Gurevich et al, 1989], the movement of tectonic plate [Gershenzon, 1994b; Gershenzon et
al, 2009a, Gershenzon et al, 2011] and friction
processes[Gershenzon & Bambakidis, 2013].
Mechano-electromagnetic phenomena in ionic crystals:
There are a few known mechano-electromagnetic
phenomena in ionic crystals including the non-classical piezoelectric effect
(Stepanov effect): the movement of electrically charged dislocation under
mechanical stress. Most likely this effect is important in phenomena observed
in monocrystals such as the generation of electromagnetic impulse during
rupture [Gershenzon et al, 1986b], the influence of a static magnetic field on
the mechanical strength of samples [Gershenzon et al, 1988; Biadzhi et al,
1990] as well as on the direction of rupture propagation [Gershenzon et al,
1986c], and the influence of ultraviolet emission on microcrack formation
[Gershenzon et al, 1987a]. As a theoretician I have worked with a group of
experimentalists who discovered the aforementioned effects.
Tectono-electromagnetic
phenomena:
During the past 40
years a wealth of seismo-electromagnetic (SEM) data has accumulated which has
been interpreted as having some relation to pre-seismic and seismic processes. The
search for SEM anomalies has spanned a wide frequency range from quasi-static
(periods of weeks or months) up to radio frequencies (<50 MHz). Both magnetic and electric fields have been
measured, using detectors below ground as well as above ground. A partial list
of the types of anomaly which have been reported includes: tectonomagnetic
(local quasi-static changes of the geomagnetic field); electrotelluric (local
quasi-static changes of the electrotelluric field over periods of week, hours
or minutes); magnetic fluctuations in the ultra-low frequency (ULF) range (10-2
to 10Hz); electromagnetic emission in the radio-frequency range (1 kHz to 50
MHz). For over 20 years I have been developing the unified model(s) describing
these phenomena [Gokhberg et al, 1984; Gershenzon et al, 1987a; Gershenzon et
al, 1987b; Gershenzon & Gokhberg, 1989; Gershenzon et al, 1989;
Dobrovol'sky et al, 1989; Gershenzon et al, 1990; Gershenzon & Gokhberg,
1992a; Gershenzon & Gokhberg, 1992b; Gershenzon & Gokhberg, 1993;
Gershenzon et al, 1993a; Gershenzon & Gokhberg, 1994; Gershenzon &
Bambakidis, 2001; Hunt et al, 2006].
Seismo-electromagnetic
phenomena:
Seismic waves are commonly used for
prospecting the upper earth crust. Usually seismic waves generate an
electromagnetic field due to variety of mechano-electromagnetic effects, which
can be used as complimentary information to the seismic data. I had been
modeling the parameters of electromagnetic response due to seismic wave
[Gershenzon, 1992a; Gershenzon, 1992b; Wolfe et al, 1996] and seismic impulse
[Gershenzon et al, 1993b].
Nuclear
Magnetic Resonance:
Nuclear magnetic resonance (NMR) spectroscopy
is a phenomenon widely used in chemistry, biochemistry, solid state and medical
imaging. All applications require radio-frequency (rf) pulses for sample excitation. The growing demand
for rf pulses with given
characteristics requires new methods/algorithms for their design. One of the
most advance methods is based on optimal control theory. I’m developing
theoretical and computational algorithms for rf pulse
design utilizing optimal control theory [Geshenzon et al, 2007; Geshenzon et
al, 2008; Geshenzon et al, 2009(b); Skiner & Gershenzon, 2010; Skinner et al, 2011; Skinner et al, 2012 (a) and (b); Spindler et al,
2012; Nimbalkar et al, 2013]. These pulses have
important applications for improved performance in NMR.
Magnetosphere-Ionosphere
plasma:
Various types of
geomagnetic variations monitored on the Earth’s surface are manifestations of
complicated processes due to the interaction of the solar wind with the
magnetosphere and ionosphere. Some of these variations can be explained by
hydrodynamic instabilities in the E-layer of the ionosphere [Al'perovich &
Gershenzon, 1981] or the appearance of various types of inhomogeneities
[Al'perovich et al, 1986a; Al'perovich et al, 1986b; Al'perovich et al, 1986c].
The Van Allen belt generates specific low-frequency geomagnetic variations
usually appearing during geomagnetic storms. I developed a model allowing
reconstruction of Van Allen belt parameters by measurement of geomagnetic
variations [Gershenzon, 1981; Gershenzon & Krylov, 1982; Gershenzon, 1983a;
Gershenzon, 1983b; Gershenzon, 1983c; Afonina et al, 1982a; Afonina et al,
1982b].
Bioinformatics:
Gene expression is a
fundamental process involving participation of many regulatory proteins. We are
now at the preliminary stage of understanding of this multi-step multi-level
process. Less than one fourth of known human promoters can be described on the
level of basal transcription machinery by known transcription scenarios. My
colleague and I developed a computational approach, allowing classification of
eukaryotic promoters based on known transcription mechanisms as well as
prediction of new mechanisms [Gershenzon & Ioshikhes, 2005]. So far we
utilized this method for analysis of core promoter elements in human and
Drosophila promoter databases (Gershenzon & Ioshikhes, 2005; Lee et al,
2005; Gershenzon et al, 2006).
The identification of thousands of
transcription factor binding sites (TFBS) (so-called cis-regulatory elements)
for each of thousands of transcription factors is a necessary part of the
elucidation of the gene expression puzzle. Many experimental and computational
approaches have been developed during the last three decades to solve this
problem. One of the most widely applied methods for searching TFBS is
Position-Weight Matrices (PWM), yet the majority of existing PWMs provide a low
level of both sensitivity and specificity. Recently, we developed and applied a
computational algorithm allowing improvement of PWM quality based on the
putative sites revealed from the promoter database [Gershenzon et al, 2005].
