In this paper, we study the performance of an adaptive and fixed transmission schemes where the transmission probability varies according to the evolution of the cluster formation procedure or is fixed for the entire network lifetime, respectively. Also, we propose a hybrid scheme where the transmission probability can either be fixed or adaptive according to the system’s conditions. In order t...

Activity-dependent synaptic plasticity is a fundamental feature of CNS synapses. Intriguingly, the capacity of synapses to express plastic changes is itself subject to considerable activity-dependent variation, or metaplasticity. These forms of higher order plasticity are important because they may be crucial to maintain synapses within a dynamic functional range. In this study, we asked whethe...

The number of vesicles released at excitatory synapses and the number of release sites per synaptic connection are key determinants of information processing in the cortex, yet they remain uncertain. Here we show that the number of functional release sites and the number of anatomically identified synaptic contacts are equal at connections between spiny stellate and pyramidal cells in rat barre...

In the paper, we present a new procedure for deriving an exact expression for the packet failure probability in the case of multi-copy transmission with error correction mechanism based on the bit-by-bit majority decision technique. The procedure exploits multiple transmission of the same packet and, if needed, combines erroneously received packets in order to correct existing errors at the sam...

Herpes Simplex Virus type 2 (HSV-2) is a sexually transmitted infection and the most common cause of genital herpes in developing countries (1). Because of its spread and its morbidity, ability to cause sickness in the population, HSV-2 infection is of major health concern. HSV-2 infections are lifelong, but many individuals have no or mild symptoms. Therefore the majority of genital herpes inf...

We find the probability distribution of the fluctuating parameters of a soliton propagating through a medium with additive noise. Our method is a modification of the instanton formalism (method of optimal fluctuation) based on a saddle-point approximation in the path integral. We first solve consistently a fundamental problem of soliton propagation within the framework of noisy nonlinear Schröd...

The peak in influenza incidence during wintertime in temperate regions represents a longstanding, unresolved scientific question. One hypothesis is that the efficacy of airborne transmission via aerosols is increased at lower humidities and temperatures, conditions that prevail in wintertime. Recent work with a guinea pig model by Lowen et al. indicated that humidity and temperature do modulate...
