Nonlinear transport in semiconductor superlattices
… a semiclassical balance equation model for transport through a single miniband of a semiconductor superlattice subject to a spatially uniform, time-dependent external electric field and/or a constant external magnetic field. The balance equations are derived from the semiclassical Boltzmann …

Nonlinear transport in two-dimensional electron gas at large filling factors.
We studied nonlinear electrical transport in high-mobility 2D electron gas (2DEG) forming in modulation-doped GaAs/AlGaAs quantum wells. Transport nonlinearities induced by a pure dc electric field as well as by coexisting dc and microwave fields were studied at very high Landau level filling …

Integrated and scalable molecular brain mapping
… by developing technologies -- stochastic electrotransport and SWITCH -- to extend multiplexed labeling methods to larger volumes. Stochastic electrotransport selectively expedites transport of molecular probes into the tissue without damaging it. SWITCH synchronizes the labeling reaction to …

On the Dynamics of Single-Electron Tunneling in Semiconductor Quantum Dots under Microwave Radiation
… gas (2DEG) of AlGaAs/GaAs heterostructures. For transport studies, quantum dots are coupled to the drain and source contacts via tunnel barriers. Electron-electron interaction in such closed quantum dots leads to Coulomb-blockade (CB) effect and single-electron tunneling (SET) through discrete …

SOFT ADAPTIVE NANOCOMPOSITES BASED ONMETALLIC CLUSTER ASSEMBLED NETWORKS FORUNCONVENTIONAL DATA PROCESSING
… metallic networks on rigid substrates revealed nonlinear transport and resistive switching (RS) dynamics correlated to their structural organization and to substrate-dependent forming processes. The implantation of MCAF into PDMS enabled the realization of soft RS devices responsive to …

Formation of morphogen gradients
… concentration of such morphogens. Morphogen transport through the tissue has been studied in experiments which lead to the suggestion of several transport mechanisms. While diffusion in the extracellular space contributes to transport, recent experiments on the morphogen Decapentaplegic (Dpp) …

On the low-dimensional structure of Bayesian inference
… extensions. Then we turn to inference in the nonlinear non-Gaussian setting--analyzing the sparsity, decomposability, and low-rank structure of deterministic couplings between distributions. These couplings facilitate efficient computation of posterior expectations in generically non-Gaussian …
