We explore a curious but simple variant of the Bronnikov-Ellis wormhole spacetime with specific ``red-shift function'' (i.e. ${g}_{00}$) in line element. The matter required to support such geometry violates local null energy condition (NEC) only around throat and global averaged NEC integral along radial geodesics may be adjusted arbitrarily small negative values, using metric parameters. Prop...
This study examined the relationship between changes in the level of client emotional involvement as measured by the Client Experiencing Scale and Strength of Feeling Scale-Reiiised. and occurrence of in-session therapeutic phenomena as measured by the Category System of Client Com! Moments, in Person-Centred and Rational-Emotive Therapy. Judges rated client statements in (i sessions conducted ...
Come with us to read a new book that is coming recently. Yeah, this is a new coming book that many people really want to read will you be one of them? Of course, you should be. It will not make you feel so hard to enjoy your life. Even some people think that reading is a hard to do, you must be sure that you can do it. Hard will be felt when you have no ideas about what kind of book to read. Or...
We study the action of G = SL(2,R), viewed as a group definable in the structure M = (R,+,×), on its type space SG(M). We identify a minimal closed G-flow I, and an idempotent r ∈ I (with respect to the Ellis semigroup structure ∗ on SG(M)). We also show that the “ideal group” (r ∗ I, ∗) is nontrivial (in fact it will be the group with 2 elements), yielding a negative answer to a question of Ne...
In two dimensions the noninteracting density of states displays a van Hove singularity (VHS) which introduces an intrinsic electron-hole asymmetry, absent in three dimensions. We show that due to this VHS the strong-coupling analysis of tunneling spectra in high-Tc superconductors must be reconsidered. Based on a microscopic model which reproduces the experimental data with excellent accuracy, ...
We would like to thank Philip Lowe, Lars Svensson and David Gruen for helpful suggestions. We are extremely grateful to Luci Ellis for training us in the use of Mathematica 3.0. Any remaining errors are ours. The views expressed are those of the authors and should not be attributed to the Reserve Bank of Australia.
Reformulating the results of del Baño Rollin, Ferreiro-Castilla, and Utzet [3], we give necessary and sufficient conditions for the moments of the stock price in the Heston model to exist and extend Theorem 2.1 of [5]. Forde and Jacquier [5] provide necessary conditions for the moments to exist when κ > ρσ. Although this assumption is satisfied on Equity markets (because the correlation is gene...
Philip J Landrigan, Richard Fuller, Nereus J R Acosta, Olusoji Adeyi, Robert Arnold, Niladri (Nil) Basu, Abdoulaye Bibi Baldé, Roberto Bertollini, Stephan Bose-O’Reilly, Jo Ivey Boufford, Patrick N Breysse, Thomas Chiles, Chulabhorn Mahidol, Awa M Coll-Seck, Maureen L Cropper, Julius Fobil, Valentin Fuster, Michael Greenstone, Andy Haines, David Hanrahan, David Hunter, Mukesh Khare, Alan Krupni...
We study here the large-time behaviour of all continuous affine stochastic volatility models (in the sense of [15]) and deduce a closed-form formula for the large-maturity implied volatility smile. Based on refinements of the Gärtner-Ellis theorem on the real line, our proof reveals pathological behaviours of the asymptotic smile. In particular, we show that the condition assumed in [10] under ...
The α 2 s correction to the Ellis-Jaffe sum rule for the structure function g 1 of polarized deep inelastic lepton-nucleon scattering is calculated.
