Keep the ORCs at bay : how eukaryotic cells ensure one round of DNA replication per cell cycle
(Massachusetts Institute of Technology, 2020)
During each cell cycle, eukaryotic cells must faithfully replicate their genome, ensuring exactly one full copy is made. Both under-replicating or over-replicating the genome can have deleterious consequences including ...
Are two heads better than one in CAD? a comparison of various CAD working styles
(Massachusetts Institute of Technology, 2020)
Collaboration in Computer-Aided Design (CAD) has existed since the inception of CAD tools. The established norm in multi-user CAD work has been to use top-down modeling techniques wherein a complex model is divided into ...
3D organ property mapping using freehand ultrasound scans
(Massachusetts Institute of Technology, 2020)
3D organ property mapping has gained a considerable amount of interest in the recent years because of its diagnostic and clinical significance. Existing methods for 3D property mapping include computed tomography (CT), ...
Systems and control theoretic approaches to engineer robust biological systems
(Massachusetts Institute of Technology, 2020)
Synthetic biology is an emerging field of research aimed to engineer biological systems by inserting programmed DNA molecules into living cells. These DNAs encode the production and subsequent interactions of biomolecules ...
Thermal energy grid storage : liquid containment and pumping
