BACKGROUND The medical humanities is a broad area of study and practice encompassing all nontechnical or 'human' aspects of medicine. OBJECTIVE This article introduces a series in the medical humanities in Australian Family Physician. DISCUSSION The medical humanities serve three main goals: the study of the human aspects of medicine from within traditional arts disciplines of history, phil...

A structural engineer who wishes to use adhesives must understand at least the rudiments of polymer chemistry, in much the same way that a structural engineer working with metal alloys must understand at least the rudiments of metallurgy. A brief introduction to polymer material science is given in the following subsections. The underlying objective of this discussion is to simply define some o...

There are many theories of translation study, among which, Skopos theory is a new branch and can explain and instruct many translation activities. This paper puts forth some basic concepts of Skopos theory, introduces some basic rules of it, and concludes the merits and limitations of Skopos theory.

act on the upper half-plane by linear fractional transformations. We may form the quotient Y0(N) = Γ0(N)\H, a Riemann surface with finitely many cusps. Compactifying gives a curve X0(N) which is in fact defined over Q; the map z → (j(z), j(Nz)) ∈ AC realizes Y0(N) as a (highly singular) plane curve with Q-coefficients. Over a general field k of characteristic zero, the k-points of the curve X0(...

In 1986, Gerd Binnig and Heinrich Rohrer won the Nobel Prize in Physics for the invention of the scanning tunnelling microscope (STM) and the fact that it could achieve atomic resolution. They observed that if they held a metallic tip of 10 angstrom above a conductive surface, they could measure a tunnelling current in the order of a nanoampere. When the tip was then scanned over the conducting...

This report is a 5-page quick summary on the most fundamental properties of the Wigner distribution. This document is structured as follows: in the first section the context is given: we introduce the fundamental issues of the time-frequency analysis and the role of joint time-frequencies distributions; then we enumerate the ideal requirements for such distributions. In the second section we sp...

Example 1. Let us fix now an example which we will use throughout the paper; it is an abelian extension, so it does not have quite all of the structure of the general case, but it should still illustrate our results. Consider the extension Q(ζ15)/Q, which is a Galois extension of degree 8. We will just write ζ for ζ15 from now on. The Galois group Gal(Q(ζ)/Q) can be identified with (Z/15Z)∗, wh...

We give a brief introduction to probabilistic encryptions. This serves as an example how randomness plays a pivotal role in cryptographic systems that satisfy advanced security concepts.

Coloured Petri Nets (CP-nets or CPN) is a graphical oriented language for design, specification, simulation and verification of systems. It is in particular wellsuited for systems in which communication, synchronisation and resource sharing are important. Typical examples of application areas are communication protocols, distributed systems, imbedded systems, automated production systems, work ...

The notion of an amenable equivalence relation was introduced by Zimmer in the course of his analysis of orbit equivalence relations in ergodic theory (see [12]). Recently it played an important role in Monod’s striking family of examples of nonamenable groups which do not contain nonabelian free subgroups. If A is a subring of R, define H(A) to be the group of all piecewise PSL2(A) homeomorphi...
