Entropically enhanced excitability in small systems.
نویسندگان
چکیده
We consider the dynamics of small excitable systems, ubiquitous in physics, chemistry, and biology. Spontaneous excitation rates induced by system-size fluctuations exhibit sharp maxima at multiple, small system sizes at which also the system's response to external perturbations is strongly enhanced. This novel effect is traced back to algebraic features of small integers and thus generic.

Tuning molecular interactions in lipid-oligonucleotides assemblies via locked nucleic acid (LNA)-based lipids.
Hybrid nucleotide-lipids containing locked nucleic acid (LNA) show enhanced hybridization properties with complementary single strand RNAs compared to DNA lipid analogues. The LNA adenosine lipid features unique binding properties with a high binding affinity for poly-uridine and the entropically driven formation of a stable complex (K(d) ≈ 43 nM). Enhanced hybridization properties of LNA-based...
متن کاملThe growth of entropically stabilized quasicrystals
We introduce a growth model for entropically stabilized quasicrystals. The dominating feature of this model is a fluctuating growth front which enables growth near equlibrium with small phason components. We summarize the results obtained for 2D and give a first presentation of 3D calculations.
متن کاملDiscovery of an entropically-driven small molecule streptavidin binder from nucleic acid-encoded libraries.
Dehydrocholic acid was identified as a selective streptavidin binder from a PNA-tagged library. Isothermal calorimetry titration measurements showed this interaction to be entropically driven. Peptides tagged with dehydrocholic acid can be captured on a streptavidin resin and released under thermal conditions.
متن کاملEnhanced excitability of small dorsal root ganglion neurons in rats with bone cancer pain
BACKGROUND Primary and metastatic cancers that affect bone are frequently associated with severe and intractable pain. The mechanisms underlying the development of bone cancer pain are largely unknown. The aim of this study was to determine whether enhanced excitability of primary sensory neurons contributed to peripheral sensitization and tumor-induced hyperalgesia during cancer condition. In ...
متن کاملEntropic barriers for two-dimensional quantum memories.
Comprehensive no-go theorems show that information encoded over local two-dimensional topologically ordered systems cannot support macroscopic energy barriers, and hence will not maintain stable quantum information at finite temperatures for macroscopic time scales. However, it is still well motivated to study low-dimensional quantum memories due to their experimental amenability. Here we intro...
