Compact well-bounded operators [PDF]
, 2001 Every compact well-bounded operator has a representation as a linear combination of disjoint projections reminiscent of the representation of compact self-adjoint operators. In this note we show that the converse of this result holds, thus characterizing

Continuous energy adjoint transport for photons in PHITS
EPJ 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

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

Plethysm and fast matrix multiplication [PDF]
, 2018 Motivated by the symmetric version of matrix multiplication we study the plethysm $S^k(\mathfrak{sl}_n)$ of the adjoint representation $\mathfrak{sl}_n$ of the Lie group $SL_n$.

Partition function of free conformal fields in 3-plet representation
Journal of High Energy Physics, 2017 Simplest examples of AdS/CFT duality correspond to free CFTs in d dimensions with fields in vector or adjoint representation of an internal symmetry group dual in the large N limit to a theory of massless or massless plus massive higher spins in AdS d+1.

Development of a variational flux inversion system (INVICAT v1.0) using the TOMCAT chemical transport model [PDF]
Geoscientific Model Development, 2014 We present a new variational inverse transport model, named INVICAT (v1.0), which is based on the global chemical transport model TOMCAT, and a new corresponding adjoint transport model, ATOMCAT.

Adjoint SU(5) GUT model with modular S 4 symmetry
Journal of High Energy Physics, 2021 We study the textures of SM fermion mass matrices and their mixings in a supersymmetric adjoint SU(5) Grand Unified Theory with modular S 4 being the horizontal symmetry.

, 1992 We propose to induce QCD by fermions in the adjoint representation of the gauge group SU(N_c) on the lattice. We consider various types of lattice fermions: chiral, Kogut--Susskind and Wilson ones.

AIChE Journal, EarlyView.Abstract In this study, various adsorption models using neural networks were developed and integrated into a mechanistic chromatography transport model, resulting in hybrid models. A systematic screening of 10 different hybrid model structures was performed to find the optimal balance between mechanistic and data‐driven components in modeling ...

Adjoint modular Galois representations and their Selmer groups [PDF]
Proceedings of the National Academy of Sciences, 1997 In the last 15 years, many class number formulas and main conjectures have been proven. Here, we discuss such formulas on the Selmer groups of the three-dimensional adjoint representation ad(φ) of a two-dimensional modular Galois representation φ. We start with the p -adic Galois representation φ 0
