UR UNDERSTA N D I N G of the development of sleep patterns in adolescents has a dvanced considerably in the last 20 years. Along the way, theoretical models of the processes underly i n g the biological regulation of sleep have improved, and certain assumptions and dogmas have been examined and found wanting. Although the full characterization of teen sleep regulation remains to be acc o m p l ...

Consider a homogenized spectral pencil of exactly solvable linear differential operators Tλ = Pk i=0 Qi(z)λ k−i d i dzi , where each Qi(z) is a polynomial of degree at most i and λ is the spectral parameter. We show that under mild nondegeneracy assumptions for all sufficiently large positive integers n there exist exactly k distinct values λn,j , 1 ≤ j ≤ k, of the spectral parameter λ such tha...

The idea of a material body endowed with both translational and rotational degrees of freedom stems from the seminal work of the Cosserat brothers (Cosserat and Cosserat, 1909). A triad of orthonormal directors (d )i=1,3 is associated to the microstructure of each material point. The material transformation describes the displacement u of the material point and the rotation R∼ with respect to t...

We give a solution stated in the title to problem 3 of part 1 of the problems listed in the book of Eklof and Mekler [EM],(p.453). There, in pp. 241-242, this is discussed and proved in some cases. The existence of strongly λ-free ones was proved earlier by the criteria in [Sh:161] in [MkSh:251]. We can apply a similar proof to a large class of other varieties in particular to the variety of (n...

An anonymous postal survey of 200 consultants was used to audit the current prevalent practices in the management of quinsy in the UK; 101 responded. The findings reveal that on average an otolaryngology department treats 29 cases per year, the vast majority (94%) on an inpatient basis. The main initial treatment was needle aspiration combined with intravenous antibiotics. Interestingly, those ...
