Face ring multiplicity via CM-connectivity sequences
The multiplicity conjecture of Herzog, Huneke, and Srinivasan is verified for the face rings of the following classes of simplicial complexes: matroid complexes, complexes of dimension one and two, and Gorenstein complexes of dimension at most four. The lower bound part of this conjecture is also established for the face rings of all doubly Cohen-Macaulay complexes whose 1-skeleton’s connectivi...
متن کاملOn the multiplicity of linear recurrence sequences
We prove a lemma regarding the linear independence of certain vectors and use it to improve on a bound due to Schmidt on the zero-multiplicity of linear recurrence sequences. 1 Linear recurrence sequences Let {un}n∈Z be a linear recurrence sequence of complex numbers satisfying the recurrence relation un = c1un−1 + · · ·+ ctun−t, (1) for c1, . . . , ct ∈ C with ct 6= 0. We say it is of order t ...
متن کاملSphingomyelinase D from venoms of Loxosceles spiders: evolutionary insights from cDNA sequences and gene structure.
Loxosceles spider venoms cause dermonecrosis in mammalian tissues. The toxin sphingomyelinase D (SMaseD) is a sufficient causative agent in lesion formation and is only known in these spiders and a few pathogenic bacteria. Similarities between spider and bacterial SMaseD in molecular weights, pIs and N-terminal amino acid sequence suggest an evolutionary relationship between these molecules. We...
متن کاملSnakes and Spiders
Intensity information is a strong cue for segmentation but on its own cannot be used to distinguish between accidental and non-accidental alignments in a scene, thus resulting in incorrect segmentations. However, motion information can be used to distinguish between accidental and nonaccidental alignments. In this paper an integrated method using both intensity and motion information for the se...
متن کاملPatients and Spiders
an inexperienced farm worker who had lacerated a leg by the over-zealous use of a scythe; the telephone message stated that the wound was bleeding badly. On arrival at the farm, however, I found no panic and, on inspecting the deep wound, I found very little blood. The laceration had been packed with cobwebs, which had been pulled hastily from corners of the cowshed; the intricate mesh of multi...
