Why Two Renormalization Groups are Better than One
The advantages of using more than one renormalization group (RG) in problems with more than one important length scale are discussed. It is shown that: i) using different RG's can lead to complementary information, i.e. what is very difficult to calculate with an RG based on one flow parameter may be much more accesible using another; ii) using more than one RG requires less physical input in o...
متن کاملVirtual Time CSMA: Why Two Clocks Are Better than One
A new carrier sense multiple access (CShiA) algorithm, called virtual time CSMA, is described and analyzed. This algorithm uses a novel approach to granting access to the shared broadcast channel based on variable-rate clocks. Unlike other CSMA algorithms, the operation of virtual time CSMA reduces to the ideal case in the zero propagation time limit: a work-conserving, first-come first-served ...
متن کاملTrader Interoperability : Why Two Models Are Better than One
Up until now the accepted way of thinking on trader interoperability was to use a single interaction model called Federated Traders. That way of thinking is now being challenged. The preferred option emerging is two separate models: one for Distribution and one for Interworking. This separation is the result of the different requirements of distribution within the organization as opposed to the...
متن کاملTwo Are Better than One?
This paper uses Markov-switching specifications to create a hybrid model with time-varying loading on each of chartist and fundamentalist approaches. The empirical data include the U.S. dollar exchange rates of four Asian tiger countries’ currencies including NTD, SGD, HKD and KOW from 1980 to 2000. Our empirical findings are consistent with the following notions. First, the forecasting perform...
متن کاملWhen two kinases are better than one
When two kinases are better than one V idal-Eychenié et al. describe how two protein kinases team up to respond to DNA damage at stalled replication forks. DNA-dependent protein kinase catalytic subunit (DNA-PKcs) promotes the repair of DNA double-strand breaks (DSBs) by nonhomologous end joining (NHEJ). The ATR kinase, on the other hand, initiates cell cycle arrest and DNA repair after recogni...
