Efficient Design of Triplet Based Spike-Timing Dependent PlasticityApr 08 2012Spike-Timing Dependent Plasticity (STDP) is believed to play an important role in learning and the formation of computational function in the brain. The classical model of STDP which considers the timing between pairs of pre-synaptic and post-synaptic ... More
Resonance fluorescence and laser spectroscopy of three-dimensionally confined excitons in monolayer WSe$_2$Apr 19 2016Resonant optical excitation of few-level quantum systems enables coherent quantum control, resonance fluorescence, and direct characterization of dephasing mechanisms. Experimental demonstrations have been achieved in a variety of atomic and solid-state ... More
Wavelet analysis on symbolic sequences and two-fold de Bruijn sequencesJan 09 2016The concept of symbolic sequences play important role in study of complex systems. In the work we are interested in ultrametric structure of the set of cyclic sequences naturally arising in theory of dynamical systems. Aimed at construction of analytic ... More
Markov trace on a tower of affine Temperley-Lieb algebras of type $\tilde{A_{n}}$Nov 27 2013Jul 07 2015We define a tower of affine Temperley-Lieb algebras of type $\tilde{A_{n}}$. We prove that there exists a unique Markov trace on this tower, this trace comes from the Markov-Ocneanu-Jones trace on the tower of Temperley-Lieb algebras of type $A_{n}$.
Measurement of the Decays $\boldsymbol{B\toη\ellν_\ell}$ and $\boldsymbol{B\toη^\prime\ellν_\ell}$ in Fully Reconstructed Events at BelleMar 29 2017Nov 30 2017We report branching fraction measurements of the decays $B^+\to\eta\ell^+\nu_\ell$ and $B^+\to\eta^\prime\ell^+\nu_\ell$ based on 711~fb$^{-1}$ of data collected near the $\Upsilon(4S)$ resonance with the Belle experiment at the KEKB asymmetric-energy ...

(10, k) Reversible MultiplesMar 21 2015Apr 20 2015We consider the integers having the property of reversing when multiplied by a specific integer k. First, we proved that k should be either 1, 4 or 9. Second, we classify these integers as (10, 1)- reverse multiples, (10, 4)- reverse multiples and (10, ... More
