CA) reveal that DNA is synthesized when it is least likely to be hit with oxidative damage. Damaging oxidizing agents are produced by respiration. In yeast, respiration is periodic—it alternates in ‫ف‬ 40-min cycles with a stage of non-respiration called the reductive phase. This oscillation was detected decades ago, but it was never thought to be connected to cell cycle progression. Now, Kleve...

DEVELOPING a softwareintensive system is like raising a child. As Will PleasantRyan observed, both babies and code have smells, you get used to changing requirements, you have to take the long view, you can’t do it alone, and eventually you have to let go.1 I would add to Will’s most excellent simile that, although you might think you know everything up front, you certainly don’t, and therefore...

"Slime" played a brief and spectacular role in the 19th century founded by the theory of primordial slime by Ernst Haeckel. However, that substance was never found and eventually abandoned. Further scientific attention slowly began in the 1930s referring to slime as a microbial product and then was inspired by "How bacteria stick" by Costerton et al. in 1978, and the matrix material was conside...

The presentation concerns a method for tracking cycle lengths in voiced speech and breaking up vocal cycle length fluctuations in cycle length jitter and cycle length tremor. The tracking of the cycle lengths is based on a dynamic programming algorithm, which does not request that the signal is locally periodic and that the average period length is known a priori. The cycle length time series a...

in the present paper, resonant frequencies and modes of a three-atom photonic molecule and a photonic crystal placed within a cavity are numerically calculated. first, governing formulation in transverse electric field mode (te) is obtained using maxwell equations. then, an algorithm based on a finite difference scheme and matrix algebra is presented. the algorithm is then implemented in a comp...

We used functional magnetic resonance imaging (fMRI) to investigate the psychological refractory period (PRP), the delay in the response to the second of two tasks occurring in immediate succession. Our results were consistent with prior work on the PRP in that when two visual-manual tasks were presented within 100 ms of each other, the second response was delayed on the order of 500 ms, compar...

It has been argued that the psychological refractory period (PRP) effect is eliminated with two ideomotor compatible tasks when instructions stress fast and simultaneous responding. Three experiments were conducted to test this hypothesis. In all experiments, Task 1 required spatially compatible manual responses (left or right) to the direction of an arrow, and Task 2 required saying the name o...

In this paper we discuss general properties of geodesic surfaces that are (locally) biLipschitz homogeneous. In particular, we prove that they are locally doubling and there exists a special doubling measure analogous to the Haar measure for locally compact groups.
