Imagine being able to break any classical encryption algorithm in a matter of seconds. Some would say that this statement is impossible, and it is in a classical sense. But with the advent of quantum computational theory, new methods of computation and algorithms are being developed that are making this statement more realistic. Quantum computation threatens classical encryption algorithms as i...

This document talks about the usage of Simulation Data Exchange (SDX) (Moorthy 1999) in order to enable a consistent digital model of automotive factories. The scope of the digital model is to plan and analyze the factory by using different software packages. Thus the model doesn’t exist in only one application. Therefore the consistency in terms of geometry and process data needs to be guarant...

For A,B subsets of an additive group Z, we define A + B to be the sumset {a + b : a ∈ A, b ∈ B}, and kA to be the k-fold sum A + A + · · · + A of A. We also let A−B = {a−b : a ∈ A, b ∈ B} and b+A = {b}+A for a single element set {b}, a translate of A. Note that A − A is not 0 unless |A| = 1. We let k ⋄ A = {ka : a ∈ A}, a dilate of A. There are many obvious properties of “+” that can be checked...

The care of children has been integral in the historic development of orthopedics as a surgical special‐ ty. Formal fellowship training of pediatric orthopedists, however, only began in the late 1970s. Many orthopedic generalists provide emergency orthopedic care for children, and when on call, much of their charge is to determine the triage and treatment of traumatic injuries. This article wil...

Hypertension exhibits a winter peak and summer trough in countries both north and south of the equator. A variety of explanations have been proposed to account for the seasonal nature of hypertension. It is likely that this reflects seasonal variations in risk factors. Seasonal variations have been demonstrated in a number of risk factors may play essential roles for seasonality of hypertension...

A DOS attack consists of rendering a network unable to carry legitimate user data. This can be done via attacking routers directly or by flooding the network with excessive traffic. Router attacks restrict the router’s ability to forward as many packets or its ability to forward them properly. This can be achieved by abusing known vulnerabilities to modify routing tables (using protocols such a...

Prospective surveillance for influenza was performed during the 2002 Salt Lake City Winter Olympics. Oseltamivir was administered to patients with influenza like illness and confirmed influenza, while their close contacts were given oseltamivir prophylactically. Influenza A/B was diagnosed in 36 of 188 patients, including 13 athletes. Prompt management limited the spread of this outbreak.

The history of the Yale School of Medicine is illuminated by the names of many great men. A distinguished school is a living organism and the soul which inspires and guides it has been created by the dreams and the visions which have gone before. In the Yale School of Medicine, no one of our distinguished leaders has played a greater role in this creative process than Milton Winternitz. When "W...

The theme for this year’s conference is “Democracy in a Knowledge Economy.” This certainly is a timely and relevant theme from a global and national perspective. It envelops some of our core values as organizational change and development scholars and practitioners. This theme invites us all to contemplate, question, theorize, and imagine how organizations can be tools for democracy and involve...
