  • We prove that the existence of an automorphism of finite order on a Q-variety X implies the existence of algebraic linear relations between the logarithm of certain periods of X and the logarithm of special values of the Γ-function. This implies that a slight variation of results by Anderson, Colmez and Gross on the periods of CM abelian varieties is valid for a larger class of CM motives. In particular, we prove a weak form of the period conjecture of Gross-Deligne [11, p. 205]1 .

  • For diffeomorphisms of smooth compact finite-dimensional manifolds, we consider the problem of how fast the number of periodic points with period n grows as a function of n. In many familiar cases (e.g., Anosov systems) the growth is exponential, but arbitrarily fast growth is possible; in fact, the first author has shown that arbitrarily fast growth is topologically (Baire) generic for C 2 or smoother diffeomorphisms.

  • We live in an era with unparalleled opportunities to practice disease prevention based on knowledge of the earth environment. Although globally distributed early warning systems can monitor physical hazards such as earthquakes and tsunamis, chemical hazards on the other hand—whether actual or potential and natural or anthropogenically induced—remain difficult to accurately identify in time and space. Such hazards often have lengthy asymptomatic latency periods before disability or disease becomes evident....

  • IT has been already remarked that at a very early period, considerably more than three thousand years ago, the Chinese and other nations in the east understood the rudiments of the dramatic art. In their crude, anomalous representations they introduced conjurers, slight of hand men and rope dancers, with dogs, birds, monkies, snakes and even mice which were trained to dance, and in their dancing to perform evolutions descriptive of mathematical and astronomical figures.

  • IN 1837 I was a resident in Galata, one of the faubourgs of Constantinople, sufficiently near the scenes of death caused by the ravages of the plague to be thoroughly acquainted with them, and yet to be separated from the Turkish part of the population of that immense city. It is not material to the present sketch to dwell upon the subject of my previous life, or the causes which had induced me to visit the capital of the East at such a period of mortality; and I will therefore only add, that circumstances of a peculiarly painful nature...

  • The transcription factor p63 plays a pivotal role in the development and maintenance of epithelial tissues, including the ocular surface. In an effort to gain insight into the pathogenesis of keratitis caused by HSV-1, we determined the expression patterns of the p63 and Bax proteins in the Staatens Seruminstitute Rabbit Cornea cell line (SIRC). Methods: SIRC cells were infected with HSV-1 at various multiplicities and maintained for different periods of time. Virus replication was measured by indirect immunofluorescence assay and Western blot analysis.

  • Other improvements in check collection have focused on when a customer has access to funds deposited in a bank. Until the late 1980s, depository institutions were not required to make funds from check deposits avail- able for withdrawal within specif ic time frames. In 1988, the Federal Reserve Board adopted Regulation CC, Availability of Funds and Collec- tion of Checks, which implemented the Expedited Funds Availability Act. Regulation CC established maximum permissible hold periods for checks and other deposits, after which banks must make funds available for with- drawal.

We consider the case when $X$ is a tore $\Pi^2$.

  • A semiconductor material has a resistivity lying between that of a conductor and that of an insulator. However, in contrast to the granular materials used for resistors, a semiconductor establishes its conduction properties through a complex quantum mechanical behavior within a periodic array of semiconductor atoms, i.e., within a crystalline structure.

  • One of the central issues in robotics and animal motor control is the problem of trajectory generation and modulation. Since in many cases trajectories have to be modified on-line when goals are changed, obstacles are encountered, or when external perturbations occur, the notions of trajectory generation and trajectory modulation are tightly coupled.
