Higher-dimensional spinning black holes and effective field theory

Journal of High Energy Physics
We study the scalar tidal responses of spinning higher-dimensional black holes, and their effective field theory description. After constructing the effective field theory of a spinning point particle in general dimension, we apply this theory to match ...

Constraining the minimally extended varying speed of light model using time dilations

Frontiers in Astronomy and Space Sciences
The Robertson–Walker (RW) metric, derived from the cosmological principle and Weyl’s postulate, characterizes the ΛCDM cosmological model. Traditionally, in this framework, the assumption of a constant speed of light leads to specific cosmological time ...

Phenomenology of transition radiation at radio frequencies from ultrahigh-energy showers

EPJ Web of Conferences, 2017
We explore transition radiation at MHz-GHz frequencies as a possible way to detect ultrahigh-energy (UHE) particles. We have developed a general method to calculate transition radiation that extends the well-known Zas-Halzen-Stanev (ZHS) algorithm.

String Cosmology [PDF]

Proceedings of European Physical Society Europhysics Conference on High Energy Physics — PoS(EPS-HEP 2009), 2010
A brief overview of various branches of contemporary string cosmology is given with an emphasis on moduli stabilization, de Sitter vacua, inflation, cosmic strings and primordial gravitational waves.

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

From Particle to Purpose: A Systems‐Theoretical Model of Unity and Coherent Adaptation

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This paper develops a conceptual integration that bridges classical systems theories with insights from the Islamic intellectual tradition, focusing on the notion of zerre (particle) as articulated by Said Nursî. We reinterpret zerre as a systems‐theoretical agent that exhibits lawful responsiveness without autonomy, offering a new lens on how

Through the looking-glass, and what AdS found there: quantum particle production with a Whittaker spectrum

Journal of High Energy Physics
Parity-inverted anti-de Sitter space — “flipped AdS” — is studied through the accelerating boundary correspondence of a moving mirror trajectory. The particle production exhibits positive energy flux and a finite total energy (unlike AdS and de Sitter ...

Probe brane dynamics on cosmological brane backgrounds

Physics Letters B, 2014
We consider the dynamics of a single probe brane on various cosmological brane backgrounds. The on-shell condition of the static probe brane leads to the supersymmetric intersection rules for static BPS configurations, though the cosmological backgrounds

Post‐Traumatic Growth in the Global South: Possibilities in Relational Ethics from Communities to Classrooms

TESOL Quarterly, EarlyView.
Abstract This article reports on a qualitative study of the way instructors and students understand and respond to traumatizing events in a Sri Lankan university. It shows how the attitudes and practices in the society at large are carried over to classrooms even though local institutions do not have a programmatic trauma‐informed pedagogy.

Autopsy, deathways, and intercultural healthcare in the southern Peruvian Andes Autopsie, pratiques mortuaires et soins de santé interculturels dans le sud des Andes péruviennes

Journal of the Royal Anthropological Institute, EarlyView.
While death remains a popular topic for anthropology, relatively few ethnographic accounts consider the modern bureaucratic processes accompanying it. One such process is public health autopsy, which scholars have largely taken for granted. Existing analysis has regarded it as a form of ‘cultural brokering’ and autopsy reluctance in communities is seen,
