Little is known about how listeners judge phonemic versus allophonic (or freely varying) versus post-lexical variations in voice quality, or about which acoustic attributes serve as perceptual cues in specific contexts. To address this issue, native speakers of Gujarati, Thai, and English discriminated among pairs of voices that differed only in the relative amplitudes of the first versus secon...

We prove a relation between several easy-to-define numerical invariants of generic knots in H × S, and discuss its implication to contact geometry. 1. Definitions of Invariants The 2-dimensional hyperbolic space H2 is defined to be the upper half plane {(x, y) ∈ R2| y > 0} equipped with the metric ds2 = dx +dy y2 . STH2 is the unit tangent bundle of H2, i.e., the S1-bundle over H2 formed by tan...

توسعه سطح زیر کشت گردو در سال های اخیر با استفاده از نهال های بذری انجام شده و این مسئله غیریکنواختی زیادی در عملکرد و کیفیت میوه در باغ های احداث شده به وجود آورده است. با توجه به اهمیت معرفی ارقام جدید در گردو، در این بررسی 21 ژنوتیپ انتخابی داخلی به دلیل باردهی منظم و عملکرد بالا و تحمل به سرمای بهاره انتخاب و با سه رقم خارجی هارتلی، چندلر و پدرو و دو رقم گرده دهنده فرانکت و روند د مونتیگناک...

The recent development of a technique for quantitative measurement of conjunctival microvascular permeability has permitted detailed pharmacological evaluation of H1- and H2-receptor involvement in histamine-induced increases in conjunctival microvascular permeability and the role of histamine in microvascular permeability changes associated with immediate hypersensitivity responses in the conj...

We consider a Heegaard splitting M = H1 ∪S H2 of a 3-manifold M having an essential disk D in H1 and an essential surface F in H2 with |D ∩ F | = 1. From H1∪SH2, we obtain another Heegaard splitting H′ 1∪S′ H′ 2 by removing a neighborhood of F from H2 and attaching it to H1. As an application, by using a theorem due to Casson and Gordon, we give examples of 3-manifolds admitting two Heegaard sp...

Genomic clones of nm23-H1 and -H2 were isolated. The nm23-H1 and -H2 genes were located in a tandem array 4 kilobases apart. Each genome contained 5 exons and most of the splicing sites in the exon-intron junctions of two isotypes were essentially identical. A probe derived from intron 4 of nm23-H1 was used to examine the loss of heterozygosity (LOH) in primary colorectal carcinomas. Twenty-nin...

Non-flagellate H2 mutants were isolated from a phase-2 stable strain, SJW806 H1-gt- H2-enxon vh2-, a derivative of Salmonella typhimurium. By transductional crosses a deletion map and a recombination map of the H2 gene were made. There are three regions especially rich in nonflagellate mutational sites. By the use of the deletion map, mutational sites of 21 flagellar shape mutants were also det...

We prove the conjecture of Seymour (1993) that for every apex-forest H1 and outerplanar graph H2 there is an integer p such that every 2-connected graph of pathwidth at least p contains H1 or H2 as a minor. An independent proof was recently obtained by Dang and Thomas (arXiv:1712.04549).

در این رساله پیش نیازهای لازم در ارتباط با عملگرهای الحاقی بسته و بسته شدنی را بیان می کنیم و سپس به مطالعه مولفه های طیفی عملگر خودالحاق ماتریسی که توسط عملگر متقارن ماتریسی به شکل l [ab b*c] روی فضای هلیبرت h2×h1 می باشد، می پردازیم. درایه های a و b و c الزاما عملگرهای کراندار روی فضاهای h1 و h2 یا بین آنها نیستند. تحت فرضیات مناسب بست عملگر (l)l0 را مورد مطالعه قرار می دهیم. در پایان حلالهای...

Given a finite or infinite graph G and positive integers `, h1, h2, h3, an L(h1, h2, h3)labelling of G with span ` is a mapping f : V (G) → {0, 1, 2, . . . , `} such that, for i = 1, 2, 3 and any u, v ∈ V (G) at distance i in G, |f(u)−f(v)| ≥ hi. A C(h1, h2, h3)-labelling of G with span ` is defined similarly by requiring |f(u)− f(v)|` ≥ hi instead, where |x|` = min{|x|, `− |x|}. The minimum sp...
