Lattice based cryptography is gaining more and more importance in the cryptographic community. It is a common approach to use a special class of lattices, so-called ideal lattices, as the basis of lattice based crypto systems. This speeds up computations and saves storage space for cryptographic keys. The most important underlying hard problem is the shortest vector problem. So far there is no ...

The ultrafiltration of plasma in the mammalian glomerulus is the first step in the processing of blood by the kidney. Proper functioning of this process is critical to the kidney’s ability to effectively eliminate waste and retain desirable substances. The glomerular barrier has long been regarded as both a size and charge selective screen for plasma solutes. The origin of this selectivity is f...

Polyacrylamide (PAM) is a water-soluble polymer with strong cohesiveness and water absorption capacity, it has been widely used to modify soil structural stability. However, little information available on the impact of PAM application aggregate-breaking process purple soils in hilly areas southwestern China. Therefore, current study aimed examine influence aggregate stability terms different b...

Progression to end-stage renal disease is common in chronic nephropathies, independent of the initial insult. While genetic factors may contribute to susceptibility and progression of renal disease, proteinuria has been documented as an independent predictor of outcome. Reduction of urinary protein levels by restoration of glomerular sieving function with renin-angiotensin system (RAS) blockers...

Novel MCO high-flux membranes for hemodialysis have been developed with optimized permeability, allowing for filtration close to that of the natural kidney. A comprehensive in vitro characterization of the membrane properties by dextran filtration is presented. The sieving profile of pristine membranes, as well as that of membranes exposed to blood for 40 minutes, are described. The effective p...

To overcome the large memory requirement of classical lattice sieving algorithms for solving hard lattice problems, Bai–Laarhoven–Stehlé [ANTS 2016] studied tuple lattice sieving, where tuples instead of pairs of lattice vectors are combined to form shorter vectors. Herold–Kirshanova [PKC 2017] recently improved upon their results for arbitrary tuple sizes, for example showing that a triple sie...

Applying pore size analysis, Monte Carlo simulations, and transition state theory, we study the molecular sieving properties of recently discovered crystalline exotic cubic carbon allotropes (Hu et al., J. Phys. Chem. C, 2012, 116, 24233-24238) at 298 K and infinite dilution. The fcc-C10 cubic carbon crystal shows unusual molecular sieving characteristics. The carbon cavities of the fcc-C10 cub...
