We construct the scalar and graviton propagator in quasi de Sitter space up to first order in the slow roll parameter ǫ ≡ −Ḣ/H2. After a rescaling, the propagators are similar to those in de Sitter space with an ǫ correction to the effective mass. The limit ǫ → 0 corresponds to the E(3) vacuum that breaks de Sitter symmetry, but does not break spatial isotropy and homogeneity. The new propagato...

Consider Fritz, who is nowadays a happy resident of Saarbrücken. On sunny Saturdays, Fritz has the habit of barbecuing Bratwurst with his friends in his yard and going thereafter to his local, the Nächstestrasse Biergarten, ‘NB’ for short. Fritz may have a couple of beers while eating his Bratwurst at home, but nothing which compares to the amount he will drink thereafter at the beer garden. Th...

We runners worry a lot about injuries. Run long enough, far enough, fast enough and something is sure to ache, break, swell, tear, twist, bleed, blister or grow arthritic. The usual suspects: feet, ankles, knees, hips, back. On the other hand, there are parts of our bodies we never expect to fail. We pride ourselves in our heart and our lungs. As runners pound out mile after mile, year after ye...

The paper reports on a new approach to automatic generation of back-of-book indexes for Chinese books. Parsing on the level of complete sentential analysis is avoided because of the inefficiency and unavailability of a Chinese Grammar with enough coverage. Instead, fundamental analysis particular to Chinese text called word segmentation is performed to break up characters into a sequence of lex...

our city's slums. A fire, unusual in its intensity, lit her brown eyes? unusual, even for one of her race. Her face was a narrow oval, her features classically perfect, her skin a fine transparent brown through which burned an enchanting glow; her hair, coal black and shining with a luster that 110 hair oil could impart, was drawn back from a low, smooth forehead. Her slender figure had a willo...

A cluster growth model is proposed to study chiral symmetry breaking in stirred crystallization from an achiral element. Achiral monomers are assumed to coagulate to form chiral clusters from dimers to hexamers. Due to the stirring, the hexamers break into dimers. The coagulation of two dimers into a tetramer also occurs. The fixed point analysis of coupled rate equations of cluster densities a...

The atomic theory of matter has a long history, in some ways all the way back to the ancient Greeks (Democritus ca. 400 BCE suggested that all things are composed of indivisible “atoms”). From what we can observe, atoms have certain properties and behaviors, which can be summarized as follows: Atoms are small, with diameters on the order of 0.1 nm. Atoms are stable, they do not spontaneously br...

We have developed a two-level case-based reasoning architecture for predicting protein secondary structure. The central idea is to break the problem into two levels: first, reasoning at the object (protein) level, and using the global information from this level to focus on a more restricted problem space; second, decomposing objects into pieces (segments), and reasoning at the internal structu...

Özet Spondilodiskit, iyatrojenik girişimler sonrası gelişebilen ve göz önünde bulundurulması gereken ciddi ve önemli bir klinik sorundur. Transrektal ultrasonografi (TRUS) eşliğinde yapılan prostat biyopsisi sonrasında spondilodiskit çok nadir olarak görülmektedir. TRUS eşliğinde yapılan prostat biyopsisi sonrasında ciddi sırt ağrısı, intermitant yüksek ateş, iştahsızlık ve yorgunluk semptomlar...
