A Novel Segment-switching Strategy with the Current Transient Overshoot Suppression for Segmented Long-Stator Linear Motor

open access: yesCES Transactions on Electrical Machines and Systems
The segmented power supply scheme for long-stator linear motor facilitates reducing power capacity and achieving a high power factor. However, the segment-switching process leads to overcurrent under high-speed conditions.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

A Review of Optimization Methods for Pole-Shoe Structures in Large-Scale Salient Pole Synchronous Motors

open access: yesCES Transactions on Electrical Machines and Systems
Optimizing the rotor pole-shoe structure of large salient pole synchronous motors is critical for improving their performance and efficiency, allowing for enhanced responsiveness to grid demands and adjustments in operating conditions.

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

open access: yesMolecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

Influence of Polytetrafluoroethylene Content, Compaction Pressure, and Annealing Treatment on the Magnetic Properties of Iron-Based Soft Magnetic Composites

open access: yesMolecules
To improve the magnetic properties of iron-based soft magnetic composites (SMCs), polytetrafluoroethylene (PTFE) with excellent heat resistance, electrical insulation, and extremely high electrical resistivity was chosen as an insulating coating material

High power density molten carbonate fuel cells [PDF]

open access: yes, 1995
Our results to date indicate that the specific power of the MCFC can be increased from 1200 W/m{sup 2} to above 2000W/m{sup 2} through the use of advanced components such as the double doped LiFeO{sub 2} cathode and pressurized operation.

Materials Processing by High Power and High Power Density Diode Laser.

open access: yesThe Review of Laser Engineering, 2000
Recently, high power and high power density diode lasers have been developed for their superiority of conversion efficiency as compared to conventional CO2 or Nd: YAG lasers. Materials processing using these lasers are reviewed and the 2kW class high power density diode laser is introduced in relation to its materials processing characteristics.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

A Review of Research Methods for Stator Temperature Monitoring in PMSM

open access: yesCES Transactions on Electrical Machines and Systems
High-density permanent magnet synchronous motors (PMSMs) are widely used in electric drive systems. However, they are susceptible to temperature influences under complex operating conditions, and prolonged operation at high temperatures can first damage ...

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.
