String duality and nonsupersymmetric strings [PDF]

open access: yesPhysical Review D, 1998
In recent work Kachru, Kumar and Silverstein introduced a special class of non-supersymmetric type II string theories in which the cosmological constant vanishes at the first two orders of perturbation theory. Heuristic arguments suggest the cosmological constant may vanish in these theories to all orders in perturbation theory leading to a flat ...

Ligamentum arteriosum and its telocytes: An ultrastructure description

open access: yesThe Anatomical Record, Volume 306, Issue 1, Page 187-192, January 2023., 2023
Abstract Results from my study have shown in 2022 the existence of telocytes (TCs) in mice ligamentum arteriosum (LA). Telocytes (TCs) are unique interstitial or stromal cells of mesodermal origin, defined by long cellular extensions called telopodes (Tps) which form a network, connecting them to surrounding cells. These Tps have dilated portions named

Asymptotically free AdS3/CFT2

open access: yesJournal of High Energy Physics, 2022
We propose a new AdS 3 /CFT 2 duality, in which the bulk string theory has a target spacetime AdS 3 times a squashed three-sphere S ♭ 3 $$ {\mathbbm{S}}_{\flat}^3 $$ , and the dual CFT 2 is a symmetric product of sigma models on ℝ ϕ × S ♭ 3 $$ {\mathbbm ...

Unity of Superstring Dualities [PDF]

open access: yes, 1994
The effective action for type II string theory compactified on a six torus is $N=8$ supergravity, which is known to have an $E_{7}$ duality symmetry. We show that this is broken by quantum effects to a discrete subgroup, $E_7(\Z)$, which contains both ...

Open-string T-duality and applications to non-geometric backgrounds

open access: yesJournal of High Energy Physics, 2018
We revisit T-duality transformations for the open string via Buscher’s procedure and work-out technical details which have been missing so far in the literature.

N = 1 string duality [PDF]

open access: yesPhysics Letters B, 1995
We discuss duality between Type IIA string theory, eleven-dimensional supergravity, and heterotic string theory in four spacetime dimensions with $N=1$ supersymmetry. We find theories whose infrared limit is trivial at enhanced symmetry points as well as theories with $N=1$ supersymmetry but the field content of $N=4$ theories which flow to the $N=4 ...

Altruism in death: Attitudes to body and organ donation in Australian students

open access: yesAnatomical Sciences Education, Volume 16, Issue 1, Page 27-46, January/February 2023., 2023
Abstract Health education, research, and training rely on the altruistic act of body donation for the supply of cadavers. Organ transplantation and research rely on donated organs. Supply of both is limited, with further restrictions in Australia due to requirements for a next‐of‐kin agreement to donation, irrespective of the deceased's pre‐death ...

Electric/magnetic duality and its stringy origins [PDF]

open access: yes, 1995
We review electric/magnetic duality in $N=4$ (and certain $N=2$) globally supersymmetric gauge theories and show how this duality, which relates strong to weak coupling, follows as a consequence of a string/string duality.
