In previous simulations of hippocampus-dependent and prefrontal cortex-dependent tasks, we demonstrated the use of one-shot short-term buffering with time compression that may be achieved through persistent spiking activity during theta rhythm. A biophysically plausible implementation of such a first-in first-out buffer of short sequences of spike patterns includes noise and differences between...

BACKGROUND AND AIMS The use of sugar by dental plaque microorganisms leads to acid formation from the bacteria metabolism, which determines a decrease of pH onto teeth surfaces. The value of the critical pH is 5.2-5.5. We aimed to evaluate the capacity of patients to change their diet towards caries prevention after acknowledging the values of saliva parameters (pH, buffer capacity). MATERIAL...

Phase change memory (PCM) is a promising memory technology that can offer higher memory capacity than DRAM. Unfortunately, PCM’s access latencies and energies are higher than DRAM and its endurance is lower. DRAM-PCM hybrid memory systems use DRAM as a cache to PCM, to achieve the low access latencies and energies, and high endurance of DRAM, while taking advantage of the large PCM capacity. A ...

Cationic polymers obtained via partial reduction of poly(2-ethy-2-oxazoline)s were studied on their cytocompatibility and buffer capacity in acidic environment.

Thirty-nine soils from northern New South Wales were used to examine the effects of phosphate buffer capacity on (i) the extraction of labile phosphate by four soil tests, (ii) the relationships between the four soil tests, and (iii) the critical level of each soil test required for near-maximum yield of wheat under field conditions. The results confirmed the principle, recently proposed by the...

The issue of buffer sizing is rightly receiving increasing attention with the realization that the bandwidth delay product rule-ofthumb is becoming unsustainable as link capacity continues to grow. In the present paper we examine this issue from the light of our understanding of traffic characteristics and the performance of statistical bandwidth sharing. We demonstrate through simple analytica...

This paper describes the impact that buffer management has on network performance for a cut-through 1D ring. Such network provides only one routing alternative between each pair of nodes. The network is kept simple to illustrate the significance of buffer management for all virtual cut-through networks. Besides, 2D and 3D torus, among other networks, can be seen as a collection of interlinked 1...

We study the interaction between an MIMD (Multiplicative Increase Multiplicative Decrease) congestion control algorithm and a Drop Tail buffer. We consider the problem in the framework of deterministic hybrid models. We first show that the hybrid model of the interaction between the MIMD congestion control and bottleneck router always converges to a cyclic behavior that can be of only two diffe...

Network throughput can be increased by dividing the buffer storage associated with each network channel into several virtual channels [DalSei]. Each physical channel is associated with several small queues, virtual channels, rather than a single deep queue. The virtual channels associated with one physical channel are allocated independently but compete with each other for physical bandwidth. V...
