The authors describe a new rhinoplasty operation that is entirely subperichondrial and preserves both Pitanguy's ligament and the scroll ligament. They believe that dissec-tion in the subperichondrial plane is less traumatic than in the sub-superficial musculoaponeurotic system (sub-SMAS) or subcutaneous plane and that restoring the integrity of the ligaments minimizes the potential for a supra...

We previously reported that low vision readers do not benefit from a rapid serial visual presentation (RSVP) display relative to a scroll display. Each reader in those studies was presented with only one letter size, and it was the same for both displays. In the current study, we systematically varied the size of the letters and compared reading rates from the 2 displays for letters that were 2...

A new circuit design is proposed for generating grid-scroll chaos in the phase plane by using a second-order linear system with a control of double-hysteresis series. The double-hysteresis series is constructed in a systematic way by using the basic double-hysteresis building blocks. With the proposed scheme, the number of scrolls can be arbitrarily assigned, and the multi-scroll chaotic attrac...

In general, the application of the meaning function T P to a normal logic program P results in innnite expressions and, hence, is infeasible in practice. On the other hand, the iteration of T P is of interest for several elds in AI. Therefore, we introduce a new representation of interpretations and adopt T P to this. The resulting function always results in nite expressions of tractable length...

The completeness of normal rational curves, considered as (q + 1)-arcs in PG(n, q), is investigated. Previous results of Storme and Thas are improved by using a result by Kovacs. This solves the problem completely for large prime numbers q and odd nonsquare prime powers q = p2h+l with p prime, p > po(h), h>\,1where po(h) is an odd prime number which depends on h.

Recruitment of stretch-activated channels, one of the mechanisms of mechano-electric feedback, has been shown to influence the stability of scroll waves, the waves that underlie reentrant arrhythmias. However, a comprehensive study to examine the effects of recruitment of stretch-activated channels with different reversal potentials and conductances on scroll wave stability has not been underta...

The double-scroll attractor that can be produced by a wide class of nonlinear electronic circuits is known to contain periodic orbits of all types under certain operating conditions. We identify the branched manifold that describes the double-scroll attractor under these operating conditions. We then show that Ghrist's universal template is embedded as a subtemplate in the double-scroll templat...

A k–nucleus of a normal rational curve in PG(n, F ) is the intersection over all k–dimensional osculating subspaces of the curve (k ∈ {−1, 0, . . . , n− 1}). It is well known that for characteristic zero all nuclei are empty. In case of characteristic p > 0 and #F ≥ n the number of non–zero digits in the representation of n+ 1 in base p equals the number of distinct nuclei. An explicit formula ...

Unidirectional and diffusive coupling of identical n-double scroll cells in a one-dimensional cellular neural network is studied. Weak coupling between the cells leads to hyperchaos, with n-double scroll hypercube attractors observed in the common state subspace of the cells. Individually the cells remain behaving as n-double scrolls. The n-double scroll hypercubes are filled with multiple scro...

Scroll waves in excitable media, described by the Barkley model, are studied. In the parameter region of weak excitability, negative tension of wave filaments is found. It leads to expansion of scroll rings and instability of wave filaments. A circular filament tends to stretch, bend, loop, and produce an expanding tangle that fills up the volume. The filament does not undergo fragmentation bef...
