Retroactivity Attenuation in Bio-Molecular Systems Based on Timescale Separation
TLDR
A mechanism that exploits the natural timescale separation present in bio-molecular systems to attenuate retroactivity, which is certainly desirable in any (engineered or natural) signal transmission system. Expand

Efficient 3-D TOF PET Reconstruction Using View-Grouped Histo-Images: DIRECT—Direct Image Reconstruction for TOF
TLDR
We present the Direct Reconstruction for TOF data (DIRECT) approach, working directly in image space and allowing very efficient implementation of reconstruction and data correction operations, without compromising image quality. Expand

Tuning Genetic Clocks Employing DNA Binding Sites
Periodic oscillations play a key role in cell physiology from the cell cycle to circadian clocks. The interplay of positive and negative feedback loops among genes and proteins is ubiquitous in theseExpand

TLDR
A bio-molecular system can be rendered insensitive to impedance-like effects, called retroactivity, by implementing a large input amplification gain in a negative feedback loop. Expand

Influence of Time-of-Flight Kernel Accuracy in TOF-PET Reconstruction
In the reconstruction of data from time-of-flight (TOF) PET systems, the timing resolution is assumed to be known accurately; in iterative reconstruction, it is included in the system model,Expand

TLDR
In this paper, we propose a phosphorylation-based design for a bio-molecular system that acts as an insulator between its upstream systems and its downstream ones in a transcriptional network. Expand
