Research on Multi-Dimensional MTPA Control for Five-Phase Interior Permanent Magnet Synchronous Motor

Energies
In order to improve the output torque/current utilization of five-phase interior permanent magnet synchronous motor (FP-IPMSM) when running below base speed, a multi-dimensional maximum torque per ampere (MTPA) control strategy based on virtual signal ...

Advantages of lateral BMD DEXA measurement and concomitant lateral spinal imaging at the point of service over conventional PA measurement in the estimation of BMD

South African Journal of Radiology, 2003
This study examined 144 sequentially selected female patients with a mean age of 53.4 years. The purpose was to assess whether instant vertebral assessment (IVA) and lateral DEXA bone mineral density (BMD) measurement in the lumbar spine would render a ...

Conserved densities [PDF]

Proceedings of the National Academy of Sciences, 1980
Conserved densities for Hamiltonian systems are shown to satisfy simple linear equations. These are essentially the original equations linearized around a particular solution. A number of examples are displayed, which pertain to many systems of physical interest.

Measuring high-density built environment for public health research: Uncertainty with respect to data, indicator design and spatial scale

Geospatial Health, 2018
Uncertainty with respect to built environment (BE) data collection, measure conceptualization and spatial scales is evident in urban health research, but most findings are from relatively lowdensity contexts. We selected Hong Kong, an iconic high-density

Diffeomorphic density registration

, 2018
In this book chapter we study the Riemannian Geometry of the density registration problem: Given two densities (not necessarily probability densities) defined on a smooth finite dimensional manifold find a diffeomorphism which transforms one to the other.

Sequential density

Topology and its Applications, 2003
A subset \(A\) of a topological space \(X\) is said to be sequentially dense in \(X\) if every point of \(X\) is the limit of a sequence in \(A\). A space \(X\) is called sequentially separable if it has a sequentially dense countable subset, and is called strongly sequentially separable if \(X\) is separable and every countable dense subset of \(X ...

The maximum density droplet to lower density droplet transition in quantum dots

, 2005
We show that, Landau level mixing in two-dimensional quantum dot wave functions can be taken into account very effectively by multiplying the exact lowest Landau level wave functions by a Jastrow factor which is optimized by variance minimization.

Cyclic nucleotide signaling as a drug target in retinitis pigmentosa

FEBS Letters, EarlyView.
Disruptions in cGMP and cAMP signaling can contribute to retinal dysfunction and photoreceptor loss in retinitis pigmentosa. This perspective examines the mechanisms and evaluates emerging evidence on targeting these pathways as a potential therapeutic strategy to slow or prevent retinal degeneration.

TRAF2 binds to TIFA via a novel motif and contributes to its autophagic degradation

FEBS Letters, EarlyView.
TRAF family members couple receptor signalling complexes to downstream outputs, but how they interact with these complexes is not always clear. Here, we show that during ADP‐heptose signalling, TRAF2 binding to TIFA requires two short sequence motifs in the C‐terminal tail of TIFA, which are distinct from the TRAF6 binding motif.
