Analyses, Modeling, and SVPWM Control of a Three-Level T-NPC Inverter to Reduce Common-Mode Voltage Under Open-Circuit Fault in a Neutral-Point Switch

IEEE Access
This paper proposes a new space vector pulse-width modulation technique for reducing the common-mode voltage (SVPWM2) in a three-level T-type neutral-point-clamped voltage source inverter working under switch-open-circuit fault on a neutral-point ...

Asymmetrical Six-Phase Space Vector Pwm Scheme

Mokslas: Lietuvos Ateitis, 2014
Multiphase electric motors have smaller torque pulsations and are more reliable that their three-phase alternatives. However, standard electricity grids around the world are three-phase, so power inverter is needed to drive multiphase motors. Inverter is

"Massive" vector field in de Sitter space

, 1999
We present in this paper a covariant quantization of the ``massive'' vector field on de Sitter (dS) space based on analyticity in the complexified pseudo-Riemanian manifold.

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

Molecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

Molecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

Generalized space vector controls for MLZSI

Ain Shams Engineering Journal, 2015
This paper proposes two advanced algorithms for multilevel Z-source inverter (MLZSI), which employ space vector control (SVC) as control algorithm of cascaded H-bridge multilevel Z-source inverter; where output voltage is achieved by summing the output ...

Reduced vascular leakage correlates with breast carcinoma T regulatory cell infiltration but not with metastatic propensity

Molecular Oncology, EarlyView.
A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

On generic homogeneous vector fields

Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2022
Background. The study of dynamical systems with symmetry is of both theoretical and applied interest. Phase portraits of dynamical systems defined by homogeneous vector fields are invariant with respect to the phase space dilation group.
