The first individual case studies were published around 1990-1994, soon after MDMA was used for recreational purposes. In a comprehensive review of this case study literature, around one third of individuals had premorbid problems, while most cases did not have prior vulnerability factors [3]. Larger population surveys have found that recreational Ecstasy use is associated with significantly ra...

paths with someone who was clearly born in the wrong century — an avid knitter, a lutist, or someone who will actually sit down and write a letter. These anachronisms are harder to find in science, but they do exist. In fact, a small band of them revealed themselves during a research cruise this summer to the Arctic Ocean. You might not think to look for an 19th Century scientist on a bright re...

Cosmic microwave background (CMB) anisotropies probe the primordial density field at the edge of the observable Universe. There is a limiting precision (“cosmic variance”) with which anisotropies can determine the amplitude of primordial mass fluctuations. This arises because the surface of last scatter (SLS) probes only a finite two-dimensional slice of the Universe. Probing other SLSs observe...

The small and simple gaseous molecule ethylene (C2H4) is usually associated with ripening and senescence events in plants. Its effects have been known for ages (literally), and in the last century there have been some major breakthroughs in ethylene biology. These breakthroughs include the discovery that the molecule that hastened the ripening of fruits and caused growth distortions in plants w...

In the past few years various conjectures have been made concerning the relationship between simple theories and stable theories. The general thrust is that in a simple theory T forking should be accounted for by some kind of “stable fragment” of T . These issues were raised in discussions between Hart, Kim and Pillay in the Fields Institute in the autumn of 1996, but it is quite likely that ot...

Tables are a familiar piece of furniture commonly found in homes, offices, cafés, design centers, show rooms, waiting areas, and entertainment centers. Tables provide a familiar and convenient physical setting for people to meet, chat, look over documents, and carry out tasks that require face-to-face collaboration. Digital documents, on the other hand, are commonly used only on desktop compute...

This dissertation is in the area of Computer-Aided Design (CAD) of digital Integrated Circuits (ICs). Today’s digital ICs, such as microprocessors, memories, digital signal processors (DSPs), etc., range from a few thousands to billions of logic gates, flip-flops, and other components, packed in a few millimeters of area. The creation of such highly complex systems would not be possible without...

The new prooles of the space missions aimed at asteroids and comets, moving from y{bys to rendez{ vous and orbiting, call for new spaceeight dynamics tools capable of propagating orbits in an accurate way around these small irregular objects. Moreover, interesting celestial mechanics and planetary science problems, requiring the same sophisticated tools, have been raised by the rst images of as...

Vogt’s theorem, concerning boundary angles of a convex arc with monotonic curvature (spiral arc), is taken as a starting point to establish basic properties of spirals. The theorem is expanded by removing requirements of convexity and curvature continuity; the cases of inflection and multiple windings are considered. Positional restrictions for a spiral arc with two given curvature elements at ...
