چکیده

Abstract Light curves and color evolutions of two classical novae can be largely overlapped if we properly squeeze or stretch the timescale a target nova against that template by . Then, brightness is related to ${(M[t])}_{\mathrm{template}}={(M[t/{f}_{{\rm{s}}}]-2.5\mathrm{log}{f}_{{\rm{s}}})}_{\mathrm{target}}$?> , where M [ t ] absolute magnitude function time f s ratio timescales between novae. In previous papers this series, show many broadly overlap in time-stretched ( B − V ) 0 – $({M}_{V}-2.5\mathrm{log}{f}_{{\rm{s}}})$?> color–magnitude diagram. present paper, propose other U $({M}_{B}-2.5\mathrm{log}{f}_{{\rm{s}}})$?> I $({M}_{I}-2.5\mathrm{log}{f}_{{\rm{s}}})$?> diagrams their tracks for 16 52 novae, respectively. Here are intrinsic colors not changed stretch, magnitudes. Using these properties, considerably refine estimates distance reddening. The obtained distances reasonable agreement with those Gaia Data Release 2 catalog.

Psychophysical Measures of Two-tone Suppression and Distortion Products (2f<sub>1</sub>-f<sub>2</sub>) and (f<sub>2</sub>-f<sub>1</sub>)

Psychophysical two-tone suppression and the growth of the (2f• --f2} and • --f•) distortion products were measured in four normal-hearing young adults using a forward-masking paradigm. The stimulus parameters investigated were: (1)f• = 750 and 3000 Hz; (2)f2/f• = 1.1 l, 1.26, and 1.41; (3) L• = 50, 65, 80, and 90 dB SPL; and (4) L2 -L• varied from -20 to + 20 dB in 10-dB increments. It appears ...

Psychophysical Two-tone Suppression as a Function of Input Level for F<sub>2</sub>/f<sub>1</sub>>1.0

Psychophysical two-tone suppression was measured in three normal-hcaring young adults using the pulsation-threshold technique. The primary objective was to study the effect of L• on psychophysical twotone suppression for f2/f• > 1.0. Measurements were obtained at low and mid frequencies and for input levels ranging from 40 through 85 dB SPL. For f• --1000 or 2000 Hz, suppression i creased initi...

Formal group law homomorphisms over <i>O</i><sub><b>C</b><sub>p</sub></sub>

Let K be a finite extension of the p-adic field Qp and let F (X,Y ) and G(X, Y ) be one-dimensional formal group laws over the ring of integers OK of K. Let φ(X) be a homomorphism from F to G which is defined over the ring of integers OCp of the completion Cp of Q p . In this paper we prove that if ker(φ) is finite then there is a discretely valued subfield L ⊂ Cp such that φ(X) is defined over...

I-23: The Role of Hysteroscopy in Sub Mucosal Myoma

Hysteroscopy is a method through which endometrial cavity can be observed and manipulated transcervically. The association of sub serous fibroids and intramural fibroids with infertility is controversial. But the role of sub mucous fibroids which are reported in 5%-18% of patients as a causal factor for infertility is likely. Sub mucous fibroids are postulated to cause menometrorrhagia, sub fer...
