Motion of patterns in polariton quantum fluids with spin-orbit interaction
We report on a remarkable effect of pseudospin precession on the collective motion of exciton-polaritons in a microresonator coherently driven by a linearly polarized pump. In particular, we show that hexagonal patterns ...
Information processing with topologically protected vortex memories in exciton-polariton condensates
We show that in a nonequilibrium system of an exciton-polariton condensate, where polaritons are generated from incoherent pumping, a ring-shaped pump allows for stationary vortex memory elements of topological charge m=1 ...
Metallic nanocatalysis : an accelerating seamless integration with nanotechnology
Rapidly growing research interests surround heterogeneous nanocatalysis, in which metal nanoparticles (NPs) play a pivotal role as structure-sensitive active centers. With advances in nanotechnology, the morphology of metal ...
Fluorescence techniques used to measure interactions between hydroxyapatite nanoparticles and epidermal growth factor receptors
The potential applications of nanomaterials in therapeutics are immense and to fully explore this potential, it is important to understand the interaction of nanoparticles with cellular components. To examine the interaction ...
The hollow fiber bioreactor as a stroma-supported, serum-free ex vivo expansion platform for human umbilical cord blood cells
The bone marrow microenvironment plays an integral role in the regulation of hematopoiesis. Residing stromal cells and the extracellular matrix in the bone marrow microenvironment provide biological signals that control ...
A new method for evaluating kinesthetic acuity during haptic interaction
Although proprioceptive impairment is likely to affect in a significant manner the capacity of stroke patients to recover functionality of upper limb, clinical assessment methods currently in use are rather crude, with a ...
1.7 Gbit/in.2 gray-scale continuous-phase-change femtosecond image storage
We demonstrate high-density, multi-level crystallization of a Ge2Sb2Te5 thin film using tightly focused femtosecond laser pulses. The submicron spots with 8 distinct data storage states are written on a 1.08 μm square grid. ...

Expression, purification, crystallization and preliminary X-ray analysis of full-length human RIG-I
The human innate immune system can detect invasion by microbial pathogens through pattern-recognition receptors that recognize structurally conserved pathogen-associated molecular patterns. Retinoic acid-inducible gene I ...
A subquadratic-time algorithm for decremental single-source shortest paths
We study dynamic (1 + ∊)-approximation algorithms for the single-source shortest paths problem in an unweighted undirected n-node m-edge graph under edge deletions. The fastest algorithm for this problem is an algorithm ...
