Asymptotic formulas for a scalar linear delay differential equation

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
The linear delay differential equation $$ x'(t)=p(t)x(t-r) $$ is considered, where $r>0$ and the coefficient $p:[t_0,\infty)\to\mathbb{R}$ is a continuous function such that $p(t)\to0$ as $t\to\infty$. In a recent paper [M. Pituk, G. Röst, Bound.

Evenly positive definite function of Hilbert space and some algebraic relationship

open access: yesМатематичні Студії, 2021
A generalization of P. A. Minlos, V. V. Sazonov’s theorem is proved in the case of bounded evenly positive definite function given in a Hilbert space.

Exploring Free Matrix CFT Holographies at One-Loop

open access: yesUniverse, 2017
We extend our recent study on the duality between stringy higher spin theories and free conformal field theories (CFTs) in the S U ( N ) adjoint representation to other matrix models, namely the free S O ( N ) and S p ( N ...

On the N↔−N self-duality of su(N) theories

open access: yesNuclear Physics B
We generalize N↔−N duality of dimension formulae of SU(N) representations on a (class of the) representations with N-dependent Young diagrams, including adjoint representation.

Scientific Theories as Intervening Representations

open access: yesTheoria, 2010
In this paper we use some ideas of Hertz and Duhem to propose a new concept of representation that overcomes the dichotomy between representation and intervention.

Continuous energy adjoint transport for photons in PHITS

open access: yesEPJ Web of Conferences, 2017
Adjoint Monte Carlo can be an effcient algorithm for solving photon transport problems where the size of the tally is relatively small compared to the source. Such problems are typical in environmental radioactivity calculations, where natural or fallout

Gauging 1-form center symmetries in simple SU(N) gauge theories

open access: yesJournal of High Energy Physics, 2020
Consequences of gauging exact ℤ k C $$ {\mathbb{Z}}_k^C $$ center symmetries in several simple SU(N) gauge theories, where k is a divisor of N, are investigated.

Neural Fields for Highly Accelerated 2D Cine Phase Contrast MRI

open access: yesAdvanced Science, EarlyView.
ABSTRACT 2D cine phase contrast (CPC) MRI provides quantitative information on blood velocity and flow within the human vasculature. However, data acquisition is time‐consuming, motivating the reconstruction of the velocity field from undersampled measurements to reduce scan times. In this work, neural fields are proposed as a continuous spatiotemporal

CAD Integrated Multipoint Adjoint-Based Optimization of a Turbocharger Radial Turbine

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2017
The adjoint method is considered as the most efficient approach to compute gradients with respect to an arbitrary number of design parameters. However, one major challenge of adjoint-based shape optimization methods is the integration into a computer ...
