Celestial amplitudes from UV to IR

Journal of High Energy Physics, 2021
Celestial amplitudes represent 4D scattering of particles in boost, rather than the usual energy-momentum, eigenstates and hence are sensitive to both UV and IR physics.

Compressibility, laws of nature, initial conditions and complexity [PDF]

, 2017
We critically analyse the point of view for which laws of nature are just a mean to compress data. Discussing some basic notions of dynamical systems and information theory, we show that the idea that the analysis of large amount of data by means of an ...

Gravitational memory in higher dimensions

Journal of High Energy Physics, 2018
It is shown that there is a universal gravitational memory effect measurable by inertial detectors in even spacetime dimensions d ≥ 4. The effect falls off at large radius r as r 3−d .

Aspects of AdS2 quantum gravity and the Karch-Randall braneworld

Journal of High Energy Physics, 2022
In this paper, we use the Karch-Randall braneworld to study theories of quantum gravity in two dimensional (nearly) anti-de Sitter space (AdS2). We focus on effective gravitational theories in the setup with two Karch-Randall branes embedded in an ...

Information-Based Physics: An Observer-Centric Foundation [PDF]

, 2013
It is generally believed that physical laws, reflecting an inherent order in the universe, are ordained by nature. However, in modern physics the observer plays a central role raising questions about how an observer-centric physics can result in laws ...

A d-dimensional stress tensor for Minkd+2 gravity

Journal of High Energy Physics, 2018
We consider the tree-level scattering of massless particles in (d+2)-dimensional asymptotically flat spacetimes. The S $$ \mathcal{S} $$-matrix elements are recast as correlation functions of local operators living on a space-like cut ℳ d of the null ...

The Role of Invasive Procedures in the Treatment of Complicated Gastrointestinal Graft‐Versus‐Host Disease in Pediatric Patients

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Gastrointestinal graft‐versus‐host disease (GI GVHD) following hematopoietic stem cell transplant is typically managed with medical therapy, but surgery and angioembolization may be warranted in selected cases with life‐threatening complications.

Human Nature, the Laws of Nature, and the Nature of Environmental Law [PDF]

, 2005
The essay is divided into three parts. Part I considers the ways in which the need for environmental law derives from the tendency of human nature to cause adverse environmental consequences and the ways in which the laws of nature make it more difficult

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Asymptotic symmetries and celestial CFT

Journal of High Energy Physics, 2020
We provide a unified treatment of conformally soft Goldstone modes which arise when spin-one or spin-two conformal primary wavefunctions become pure gauge for certain integer values of the conformal dimension ∆.
