Spatially resolved manipulation of single electrons in quantum dots using a scanned probe

, 2004
The scanning metallic tip of a scanning force microscope was coupled capacitively to electrons confined in a lithographically defined gate-tunable quantum dot at a temperature of 300 mK.

Computational modelling of the pro‐ and antiarrhythmic effects of atrial high rate‐dependent trafficking of small‐conductance calcium‐activated potassium channels

The Journal of Physiology, EarlyView.
Abstract figure legend Small‐conductance calcium‐activated potassium (SK) channels are important for atrial repolarization and can be targeted for atrial‐specific antiarrhythmic treatments. We developed a computational model with a calcium sensor to study the effects of increased pacing rate (5 Hz), which enhances SK‐channel gating and forward ...

Electron-Hole Crossover in Graphene Quantum Dots

, 2009
We investigate the addition spectrum of a graphene quantum dot in the vicinity of the electron-hole crossover as a function of perpendicular magnetic field.

Mutational analysis of the genome-linked protein VPg of poliovirus [PDF]

Journal of Virology, 1988
Using a mutagenesis cartridge (R. J. Kuhn, H. Tada, M. F. Ypma-Wong, J. J. Dunn, B. L. Semler, and E. Wimmer, Proc. Natl. Acad. Sci. USA 85:519-523, 1988), we have generated single and multiple amino acid replacement mutants, as well as a single amino acid insertion mutant in the genome-linked protein VPg of poliovirus.

The Use of Artificial Intelligence for Auction Design

Journal of Economic Surveys, Volume 40, Issue 1, Page 269-285, February 2026.
ABSTRACT This paper investigates the use of artificial intelligence—specifically, model‐free reinforcement learning—as a method to simulate bidding behavior in auctions. We survey six algorithms that are particularly suitable for learning and bidding in environments with large strategy sets and incomplete information such as auctions.

Construction of a "mutagenesis cartridge" for poliovirus genome-linked viral protein: Isolation and characterization of viable and nonviable mutants [PDF]

, 1988
By following a strategy of genetic analysis of poliovirus, we have constructed a synthetic "mutagenesis cartridge" spanning the genome-linked viral protein coding region and flanking cleavage sites in an infectious cDNA clone of the type 1 (Mahoney ...

On the role of descending drive and group III/IV muscle afferent feedback in modulating corticomotoneuronal excitability during knee‐extensor exercise

The Journal of Physiology, Volume 604, Issue 3, Page 1158-1173, 1 February 2026.
Abstract figure legend Transcranial magnetic stimulation (TMS), cervicomedullary stimulation (CMS), and femoral nerve stimulation (FNS) were used to assess changes in corticomotoneuronal excitability induced by fatiguing submaximal knee‐extension contractions performed in three conditions: (1) voluntarily (VOL); (2) electrically evoked (EVO); and (3 ...

Molecular studies on a complex of potyviruses infecting solanaceous crops, and some specific virus-host interactions [PDF]

, 2003
This thesis constitutes a comprehensive analysis of the molecular and biological characteristics of three potyviruses (genus Potyvirus, family Potyviridae) naturally occurring in cultivated and wild species of family Solanaceae: Peru tomato virus (PTV ...

Echoes of the spoken past: how auditory cortex hears context during speech perception. [PDF]

, 2014
What do we hear when someone speaks and what does auditory cortex (AC) do with that sound? Given how meaningful speech is, it might be hypothesized that AC is most active when other people talk so that their productions get decoded.

Mechanical Environment Afforded by Engineered Hydrogel Critically Regulates Survival of Neural Stem Cells Transplanted in the Injured Spinal Cord via Piezo1‐Mediated Mechanotransduction

Advanced Science, Volume 13, Issue 3, 14 January 2026.
Neural stem cell transplantation shows promise for spinal cord repair, but poor graft survival limits therapeutic efficacy. This study demonstrates that increasing hydrogel stiffness from 10% to 16% concentration significantly enhances transplanted neural stem cell survival through Piezo1‐mediated mechanotransduction, revealing mechanical properties as
