BPS Solutions and New Phases of Finite-Temperature Strings [PDF]

, 2000
All high-temperature phases of the known N=4 superstrings in five dimensions can be described by the universal thermal potential of an effective four-dimensional supergravity. This theory, in addition to three moduli s, t, u, contains non-trivial winding

Therapeutic Apheresis for Intravenous Methylprednisolone‐Refractory Neuromyelitis Optica Spectrum Disorder: Clinical and Radiological Outcomes in a Single‐Center Case Series

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.

Six-Phase Space Vector PWM under Stator One-Phase Open-Circuit Fault Condition

Energies, 2018
The torque pulsation and speed pulsation of a six-phase induction machine with double Y-connected windings displaced by 30° increase after one phase of the stator winding is open-circuited. To reduce the pulsations, a method of six-phase space vector

Electromagnetical Efficiency of the Six-phase Winding

Elektronika ir Elektrotechnika, 2012
The investigation of electromagnetical efficiency of the two-layer preformed six-phase winding is presented. At first the variation of phases of the six-phase windings was determined and, on the basis of the theory of three-phase windings, the development of the electrical circuit of the analyzed winding was formed.

A novel multilevel quad-inverter configuration for quasi six-phase open-winding converter

2016 10th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG), 2016
This paper developed a novel quad-inverter configuration for multilevel six-phase asymmetrical open-winding AC converter. Proposal found to be suited for (low-voltage/high-current) applications such as AC tractions and `More-Electric Aircraft' propulsion systems. Modular power circuit comprises of standard four three-phase voltage source inverter (VSI)

Improved Performance of Wind-driven Isolated Induction Generators by Six-phase Operation [PDF]

International Journal of Computer Applications, 2012
paper describes a new, generalized and efficient steady- state model for the performance analysis of isolated six-phase induction generators. The mathematical model is formed directly from the equivalent circuit of six-phase induction generator by nodal admittance method.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Seeing Majorana fermions in time-of-flight images of spinless fermions coupled by s-wave pairing [PDF]

, 2013
The Chern number, nu, as a topological invariant that identifies the winding of the ground state in the particle-hole space, is a definitive theoretical signature that determines whether a given superconducting system can support Majorana zero modes ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
