The Mandelstam brothers in Koktebel (1916) [PDF]

Литературный факт, 2019
The article considers an episode from the biography of Osip Mandelstam and his brothers Eugene and Alexander during the two summer months of 1916, which previously had documentary contradictions in circumstances and dates. The author of the article draws

DON IS A HALF-BLOOD (ABOUT THE SPECIFICS OF THE LYRICAL LANDSCAPE IN O. MANDELSTAM'S POEM “WITH A THIN GILLETTE PLATE...”)

Известия Южного федерального университета: Филологические науки
Mandelstam's poem "With a thin Gillette plate ..." has rarely been subjected to detailed analysis and still contains riddles, the possibility of variable interpretations.

Disentangling a deep learned volume formula

Journal of High Energy Physics, 2021
We present a simple phenomenological formula which approximates the hyperbolic volume of a knot using only a single evaluation of its Jones polynomial at a root of unity.

Generalized hot attractors

Journal of High Energy Physics, 2019
Non-extremal black holes are endowed with geometric invariants related to their horizon areas. We extend earlier work on hot attractor black holes to higher dimensions and add a scalar potential.

Paul Celan and Osip Mandelstam: Poetry under the Critique of Language

Literatūra (Vilnius), 2020
The dialogue of Paul Celan, a reader and translator, with the poetry and the whole complex poetic views of Osip Mandelstam demonstrates an important general condition: both poets worked in the context of the modernist language crisis and language ...

Neural network approximations for Calabi-Yau metrics

Journal of High Energy Physics, 2022
Ricci flat metrics for Calabi-Yau threefolds are not known analytically. In this work, we employ techniques from machine learning to deduce numerical flat metrics for K3, the Fermat quintic, and the Dwork quintic.

Fubini‐Study Metric Tensor Evolution and Reduced State Distinguishability in Geometry‐Aware Optimization for Reliable Near‐Term Variational Quantum Eigensolvers

International Journal of Quantum Chemistry, Volume 126, Issue 13, July 5, 2026.
During optimization via the quantum natural gradient in a variational quantum eigensolver, the evolution of the Fubini‐Study metric suppresses irrelevant parameter directions and reduces state distinguishability near the ground state. ABSTRACT The lack of both a consistently effective and broadly reliable classical optimizer for variational quantum ...

Residue sums for superconformal indices

Journal of High Energy Physics
We study superconformal indices of four-dimensional SU (N) gauge theories with N $$ \mathcal{N} $$ = 1, 2, 4 supersymmetry. The usual representation of a gauge theory index involves multiple contour integrals and reflects the BPS spectrum at zero Yang ...

Exact thermal correlators of holographic CFTs

Journal of High Energy Physics, 2023
We compute the exact retarded Green’s functions in thermal CFTs with chemical potential and angular momenta using holography respectively. We consider the field equations satisfied by the quasi-normal modes in both charged and rotating black holes in AdS

Characterisation of Quality of Life and Its Utility as a Descriptor of Health Outcomes for People With Profound Intellectual and Multiple Disabilities: A Scoping Review of Primary Studies

Journal of Applied Research in Intellectual Disabilities, Volume 39, Issue 4, July 2026.
ABSTRACT Background Establishing the effectiveness of interventions to promote quality of life is essential to providing evidence‐based care, optimising outcomes and justifying expenditure on such provision. This review explores how quality of life for adults with profound intellectual disabilities is characterised, measured and utilised to evaluate ...
