Unitary representations of diamond groups
MATHEMATICA SCANDINAVICA, 1999 In this article the topology on the unitary dual (or on the primitive ideal space in the non type I case) of so-called (general) diamond groups is determined. Those are semidirect products \(S\ltimes N\), where \(N\) is the Heisenberg group in a certain dimension, and \(S\) is an Abelian locally compact group fixing the center of \(N\) and acting on ...

Neural Mechanisms of Object Location Memory in Huntington's Disease
Movement Disorders, EarlyView.ABSTRACT Background Object‐location memory impairment in Huntington's disease (HD) occurs from premanifest period and declines as HD progresses, however, pathogenesis of object‐location memory is unknown. The striatum and hippocampus are affected in HD, functionally interacting allowing intact object‐location memory.

ANN‐Based Green's Function Approach for Reservoir Geomechanics
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Green's functions have been a tool to analyze important reservoir geomechanics effects like subsidence, compaction, well closure, and permeability variation. However, the classical Green's function is related to linear elastic, homogenous, and geometrically simplified media.

Unitary representations of the Lorentz group [PDF]
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1945 Certain quantities are introduced which are like tensors in space-time with an infinite enumerable number of components and with an invariant positive definite quadratic form for their squared length. Some of the main properties of these quantities are dealt with, and some applications to quantum mechanics are pointed ...

The Death of USAID: How Elon Musk and Donald Trump Ended America's Foreign Aid Agency
Public Administration and Development, EarlyView.ABSTRACT USAID served for decades as a vehicle for both US soft power and foreign aid. Within the first days of the Trump administration, the agency was effectively closed, its staff told to go home and its funding frozen. It is impossible to understand the demise of USAID without understanding the broader contours of American governance during the ...

The Global Symmetry Group of Quantum Spectral Beams and Geometric Phase Factors
Advances in Mathematical Physics, 2015 We propose a cohomological modelling schema of quantum state spaces and their connectivity structures in relation to the formulation of global geometric phase phenomena. In the course of this schema, we introduce the notion of Hermitian differential line

The Function of Posterior Middle Temporal Gyrus in Conceptual Expansion
PsyCh Journal, EarlyView.ABSTRACT Conceptual expansion, referred to as the expansion of existing conceptual structures and the generation of new concepts, is a key cognitive component of creative ideation in human beings. However, the specific brain regions associated with the process of conceptual expansion remain unclear, particularly in the field of divergent thinking.

A three‐phase three‐level converter with shared flying capacitors
IET Power Electronics, EarlyView., 2023 Three‐phase multilevel converters use a high number of components which increases their size. As specific weight reduction is a work of interest for embedded system applications, this paper presents a topology aiming to optimize volume and mass for a three‐level three‐phase inverter. The number of passive and active components is reduced thanks to the ‘
