A unified approach to the performance analysis of caching systems

We propose a unified methodology to analyse the performance of caches (both isolated and interconnected), by extending and generalizing a decoupling technique originally known as Che's approximation, which provides very accurate results at low computational cost. We consider several caching policies, taking into account the effects of temporal locality. In the case of interconnected caches, our approach allows us to do better than the Poisson approximation commonly adopted in prior work. Our results, validated against simulations and trace-driven experiments, provide interesting insights into the performance of caching systems.Comment: in ACM TOMPECS 20016.

A large deviation approach to super-critical bootstrap percolation on the random graph Gn,pG_{n,p}

We consider the Erd\"{o}s--R\'{e}nyi random graph $G_{n,p}$ and we analyze the simple irreversible epidemic process on the graph, known in the literature as bootstrap percolation. We give a quantitative version of some results by Janson et al. (2012), providing a fine asymptotic analysis of the final size $A_n^*$ of active nodes, under a suitable super-critical regime. More specifically, we establish large deviation principles for the sequence of random variables $\{\frac{n- A_n^*}{f(n)}\}_{n\geq 1}$ with explicit rate functions and allowing the scaling function $f$ to vary in the widest possible range.Comment: 44 page

Unhealthy Politics of Oral Health

Editorial. Comments that a survey conducted by national advocacy group Oral Health America found that people from the U.S. are underachievers in access to dental hygiene. Measurement of success in oral health care; Proposal to implement dental hygiene practice laws; Shortage of dentists in rural and inner city communities

Antimicrobial Mouthrinses in Contemporary Dental Hygiene Practice: The Take Home Message

The article discusses the significance of antimicrobial mouthrinses to the oral hygiene of people in the U.S. Such product is vital to those with or without dental problems because its regular use reduces supragingival plaque and gingivitis. Studies reveal that an American Dental Association (ADA)-Accepted antimicrobial mouthrinse can result in a greater reduction in plaque and gingivitis than brushin

The Advanced Dental Hygiene Practitioner at the Master\u27s-Degree Level: Is It Necessary?

The article reflects on the Advanced Dental Hygiene Practitioner (ADHP) curriculum proposed by the American Dental Hygienists\u27 Association at the master\u27s degree level. It is stated that dental hygienists and ADHPs can collaborate with other health care professionals for contributing towards the advancement of quality health care to the most vulnerable populations. It is mentioned that preparation at the master\u27s degree is a logical pathway to the expanded scope of practice

Changing Perspectives on the Use of Antimicrobial Mouthrinses

As oral health care professionals, we need to make evidence-based recommendations to our patients. Studies from which we derive our recommendations need to have been conducted with scientific rigor and need to be confirmed with other welldesigned studies. Given the numerous, long-term, peer-reviewed published studies on antimicrobial mouthrinses with consistent statistically and clinically significant outcomes, it is time to change our professional thinking and practices

Information-theoretic Capacity of Clustered Random Networks

We analyze the capacity scaling laws of clustered ad hoc networks in which nodes are distributed according to a doubly stochastic shot-noise Cox process. We identify five different operational regimes, and for each regime we devise a communication strategy that allows to achieve a throughput to within a poly-logarithmic factor (in the number of nodes) of the maximum theoretical capacity.Comment: 6 pages, in Proceedings of ISIT 201
