Forty years ago is not ancient history in the medical field. However, being an eye witness to the emergence of three new infectious diseases in the northeastern United States in the 1970s left a deep impression on this author. I will relate a small portion of the amazing events that caught the attention of the medical establishment and the general public in a roughly 5-year period of medical di...
The public Alzheimer's disease (AD) research enterprise began in earnest in the mid-1970s with the creation by Congress of the National Institute on Aging at the National Institutes of Health. Today, AD research is a maturing field of study, with federal effort seeking to encourage the creativity and insights of individual investigators, and targeting special areas for emphasis. It is inspired ...
Alzheimer’s disease (AD) is the most common form of dementia in the elderly. AD is characterized by senile plaques and neurofibrillary tangles (NFTs) comprised of amyloid-β protein (Aβ) deposits and hyper-phosphorylated tau protein (p-tau), respectively. Oxidative stress-induced neuronal damage is also involved in AD pathogenesis. In the 1970s, studies showed increased levels of aluminum (Al) i...
1970s, wireless networks have become increasingly popular in the computing industry. This is particularly true within the past decade, which has seen wireless networks being adapted to enable mobility. There are currently two variations of mobile wireless networks. The first is known as the infrastruc-tured network (i.e., a network with fixed and wired gateways). The bridges for these networks ...

A mobile ad hoc network is a relatively new term for an old technology a network that does not rely on pre-existing infrastructure. Roots of this technology could be traced back to the early 1970s with the DARPA PRNet and the SURAN projects. The new twitch is the application of this technology in the non-military communication environments. Additionally, the research community has also recently...
The concept of ad-hoc networks has first arisen in 1970s. Adhoc networks act differently than other wireless networks, for each node can act as a router. For that ad-hoc networks can be used in some interesting applications. However, if the network wasn’t well constructed, it would have an inefficient performance. Interference can be considered to be one of the worst problems, the network can s...
An economic model of the online advertising market is presented, focusing on the effect of ad fraud. In the model, the market is comprised of three classes of players: publishers, advertising networks, and advertisers. The central question is whether ad networks have an incentive to aggressively combat fraud. The main outcome of the model is to answer this question in the affirmative.
