Depletion of energy from Naked Singular regions during gravitational collapse

open access: yes, 2011
A distinguishable and observable physical property of Naked Singular Regions of the spacetime formed during a gravitational collapse has important implications for both experimental and theoretical relativity.

A never‐ending story of an identity crisis or a creative reformulation of an Alevi‐mindset? What the case of Alevi youth in the German diaspora suggest today?

open access: yesStudies in Ethnicity and Nationalism, Volume 25, Issue 1, Page 48-64, April 2025.
Abstract The Alevi movement, originating more than three decades ago in Turkey and the Western European diaspora, has led to significant social and cultural shifts within Alevi communities. This movement witnessed the emergence of Alevi associations, increased religio‐political activities, and a fervent search for a redefined Alevi identity.

The Social Structure of Death Row as a Total Institution and Elements of Fatalistic Suicide

open access: yesSociology Compass, Volume 19, Issue 4, April 2025.
ABSTRACT Suicide on Death Row reveals unique and complex dynamics. While the primary objective of Death Row is to execute the inmate, the institution employs all necessary measures to prevent self‐execution. Additionally, inmates may commit a disguised suicide by waiving appeals, misleading the institution into believing it has successfully carried out

AI‐Based Crypto Tokens: The Illusion of Decentralized AI?

open access: yesIET Blockchain, Volume 5, Issue 1, January/December 2025.
ABSTRACT The convergence of blockchain and artificial intelligence (AI) has led to the emergence of AI‐based tokens, which are cryptographic assets designed to power decentralized AI platforms and services. This paper provides a comprehensive review of leading AI‐token projects, examining their technical architectures, token utilities, consensus ...

Surface-Gravity Inequalities and Generic Conditions for Strong Cosmic Censorship

open access: yes, 2003
Transforming Penrose's intuitive picture of a strong cosmic censorship principle, that generically forbids the appearance of locally naked space-time singularities, into a formal mathematical proof, remains at present, one of the most outstanding ...

de Sitter State in Heterotic String Theory

open access: yesFortschritte der Physik, Volume 72, Issue 11, November 2024.
Abstract Recent no‐go theorems have ruled out four‐dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well‐defined Wilsonian effective action and other related phenomena also appear to rule out such time‐dependent vacua with de Sitter isometries, even in the presence of quantum corrections.

Non-Supersymmetric (but) Extreme Black Holes, Scalar Hair and Other Open Problems [PDF]

open access: yes, 1997
We give a brief overview of black-hole solutions in four-dimensional supergravity theories and their extremal and supersymmetric limits. We also address problems like cosmic censorship and no-hair theorems in supergravity theories.

Iranian classical dance as a subject for empirical research: An elusive genre

open access: yesAnnals of the New York Academy of Sciences, Volume 1533, Issue 1, Page 51-72, March 2024.
Iranian classical dance is a rich resource for academic research, both for humanities scholarship and for the empirical disciplines (e.g., empirical aesthetics, experimental psychology, affective neuroscience). To support such research, this paper (a) describes the aesthetics, characteristics, and history of Iranian classical dance; (b) outlines issues
