The effect of cholesterol on the bending modulus of DOPC bilayers: re-analysis of NSE data Open
The effect of cholesterol on the bending modulus K C of DOPC lipid bilayers has been controversial.

MEDUSA: A cloud-based tool for the analysis of X-ray diffuse scattering to obtain the bending modulus from oriented membrane stacks Open
An important mechanical property of cells is their membrane bending modulus, κ . Here, we introduce MEDUSA ( ME mbrane D iff U se S cattering A nalysis), a cloud-based analysis tool to determine the bending modulus, κ , from the analysis o…

Closer look at the calorimetric lower transition in lipid bilayers Open
The thermal behavior of unilamellar vesicles has been revisited with differential scanning calorimetry to address the issue of whether it is essential to include interactions between neighboring bilayers in theories and simulations of the …

Understanding the phase behavior of a proto-biomembrane Open
The rich thermotropic behavior of lipid bilayers is addressed using phenomenological theory informed by many experiments. The most recent experiment not yet addressed by theory has shown that the tilt modulus in DMPC lipid bilayers decreas…

The bending rigidity of the red blood cell cytoplasmic membrane Open
An important mechanical property of cells is the membrane bending modulus, κ . In the case of red blood cells (RBCs) there is a composite membrane consisting of a cytoplasmic membrane and an underlying spectrin network. Literature values o…

Measuring the bending modulus of lipid bilayers with cholesterol Open
Regarding the effect on the bending modulus of adding cholesterol to lipid bilayers, recent results using neutron spin echo and nuclear magnetic resonance relaxation methods that involve linear transport properties have conflicted with ear…

On Measuring Two-Party Partisan Bias in Unbalanced States Open
Assuming that partisan fairness and responsiveness are important aspects of redistricting, it is important to measure them. Many measures of partisan bias are satisfactory for states that are balanced with roughly equal proportions of vote…

Area compressibility moduli of the monolayer leaflets of asymmetric bilayers from simulations Open
Extraction from simulations of the area compressibility moduli of the monolayers in a bilayer is considered theoretically. A statistical mechanical derivation shows that the bilayer modulus is the sum of the two monolayer moduli, as is oft…

Preface Open
Coalmining was a notoriously dangerous industry and many of its workers experienced injury and disease. However, the experiences of the many disabled people within Britain's most dangerous industry have gone largely unrecognised by histori…

Revisiting Volumes of Lipid Components in Bilayers Open
In addition to obtaining the highly precise volumes of lipids in lipid bilayers, it has been desirable to obtain the volumes of parts of each lipid, such as the methylenes and terminal methyls on the hydrocarbon chains and the head group. …

Measures of Partisan Bias for Legislating Fair Elections Open
Several measures of partisan bias are reviewed for single member districts\nwith two dominant parties. These include variants of the simple bias that\nconsiders only deviation of seats from 50% at statewide 50% vote. Also included\nare equ…

Determination of mosaicity in oriented stacks of lipid bilayers Open
Protocols are developed for characterizing and quantifying mosaicity (orientation disorder) in lipid bilayer samples.
