Nucleocytoplasmic Transport [PDF]
Science, 1996 Active transport of proteins and RNAs between the nucleus and cytoplasm is a major process in eukaryotic cells. Recently, factors that recognize transport substrates and mediate nuclear import or export have been characterized, revealing interactions that target substrates to the nuclear pore complexes, through which translocation occurs. Translocation

Dynamic structure selection and instabilities of driven Josephson lattice in high-temperature superconductors [PDF]
, 2001 We investigate the dynamics of the Josephson vortex lattice in layered high-T$_{c}$ superconductors at high magnetic fields. Starting from coupled equations for superconducting phases and magnetic field we derive equations for the relative displacements [

Development, 2013 The graded distribution of morphogens underlies many of the tissue patterns that form during development. How morphogens disperse from a localized source and how gradients in the target tissue form has been under debate for decades. Recent imaging studies and biophysical measurements have provided evidence for various morphogen transport models ranging

Urban Transportation Networks Resilience: Indicators, Disturbances, and Assessment Methods
Sustainable cities and society, 2021 Due to a surge in the frequency and intensity of disruptive events, such as natural disasters, the Covid-19 pandemic, and intentional attacks, the concept of resilience has attracted increased attention in recent years.

Integrated Modeling Approach for the Transportation Disadvantaged [PDF]
, 2007 Transportation models have not been adequate in addressing severe long-term urban transportation problems that transportation disadvantaged groups overwhelmingly encounter, and the negative impacts of transportation on the disadvantaged have not been ...

Nitrate transporters and peptide transporters
FEBS Letters, 2007 In higher plants, two types of nitrate transporters, NRT1 and NRT2, have been identified. In Arabidopsis, there are 53 NRT1 genes and 7 NRT2 genes. NRT2 are high‐affinity nitrate transporters, while most members of the NRT1 family are low‐affinity nitrate transporters.

Cell, 2017 The subfamily C ATP-binding cassette (ABCC) transporters mediate multidrug resistance and ion conductance regulation. Recent atomic or near-atomic resolution structures of three physiologically significant ABCC transporters (MRP1, SUR1, and CFTR), determined by using single-particle cryo-electron microscopy (cryo-EM), reveal structural details that ...
