We study the existence of polynomial kernels, for parameterized problems without a kernel on general graphs, when restricted to graphs bounded twin-width. Our main result is that k -Dominating Set twin-width at most 4 would contradict standard complexity-theoretic assumption. The reduction quite involved, especially get upper bound down 4, and can be tweaked work Connected Total (albeit with wo...

BACKGROUND AND AIM: An important goal of periodontal plastic surgery is the creation of attached gingiva around the teeth. In this study, the aims were to culture gingival fibroblasts in a biodegradable scaffold and measure the width of attached gingiva after the clinical procedure.METHODS: This study was carried out on 4 patients (8 sites), with inadequate attached gingiva next to at least two...

The tree width of an alternating finite automaton (AFA) measures the parallelism in all computations AFA on a given input. maximal existential (respectively, universal) A string w number choices parallel universal branches) one computation w. We give polynomial time algorithms deciding finiteness AFA’s and width. Also we algorithm that for with decides whether or not is finite. Finiteness decid...

BACKGROUND AND AIM: The present study was performed in order to assess the effect of gingival thickness on amount of gingival augmentation with and without preserving periosteum.METHODS: The study was conducted on 8 ecotype dogs aged 1-5 years. At the beginning, clinical probing depth and keratinized and attached gingiva width were measured. Totally, 64 sites were operated in this study. Perios...
