We model the evolution of the accretion disk of WZ Sagittae during the long quiescence. We find that the large amount of mass in the disk derived from the outburst luminosity is a severe constraint and demands values of αc ≈ 0.001 in contradiction to some recent suggestions. We include in our computations the formation of an inner disk hole and the growth of the disk due to redistribution of an...

We extend the notion of canonical orderings to cylindric triangulations. This allows us to extend the incremental straight-line drawing algorithm of de Fraysseix, Pach and Pollack to this setting. Our algorithm yields in linear time a crossing-free straight-line drawing of a cylindric triangulation G with n vertices on a regular grid Z/wZ× [0..h], with w ≤ 2n and h ≤ n(2d+1), where d is the (gr...

In this paper, a practical coding scheme is designed for the binary Wyner-Ziv (WZ) problem by using nested low-density generator-matrix (LDGM) and low-density paritycheck (LDPC) codes. This scheme contains two steps in the encoding procedure. The first step involves applying the binary quantization by employing LDGM codes and the second one is using the syndrome-coding technique by utilizing LD...

The quasiparticle band structures and fundamental energy gaps of the rock-salt (rs), zinc-blende (zb), and wurtzite (wz) polymorphs of CaO and AlN are calculated within the G0W0 approximation on top of a selfconsistent solution of the generalized Kohn–Sham equation with the hybrid functional HSE03. Based on these reliable electronic structures, the dielectric functions of rs-CaO, zb-AlN, and wz...

We observed the long-term behavior of the helium dwarf nova V803 Cen, and clarified the existence of at least two distinct states (a state with 77-d supercycles and a standstill-like state) that interchangeably appeared with a time-scale of 1–2 yr. We also conducted a time-resolved CCD photometry campaign during the bright outburst in 2003 June. The overall appearance of the outburst closely re...

We examine the light curve of the July-August 2001 superoutburst of WZ Sagittae. During the decline from maximum light the locally defined decay time increases from ∼ 4 d mag to ∼ 12 d mag over the first ∼ 15 d of the ∼ 25 d superoutburst, as the system faded from mV ≃ 8.5 to mV ≃ 10. The superoutburst is caused by the sudden accretion of ∼ 10 g of gas onto the white dwarf, and the deviation fr...

To serve as an initial step in developing an ideal genetic marker map for the house musk shrew, Suncus murinus, 318 comparative anchor tagged sequence (CATS) primer pairs were assessed for polymorphism ascertainment and linkage mapping. Of the 112 (35.2%) CATS primer pairs that were successfully amplified by PCR in the shrew, 18 (16.1%) showed polymorphism between two mutant strains, BAN-kc, oe...

The propagation of the fundamental symmetric Lamb mode S0 along wz-BN/AlN thin composite plates suitable for telecommunication and sensing applications is studied. The investigation of the acoustic field profile across the plate thickness revealed the presence of modes having longitudinal polarization, the Anisimkin Jr. plate modes (AMs), travelling at a phase velocity close to that of the wz-B...
