How Grid Decarbonization Reshapes Distribution Transformer Life-Cycle Impacts: A Forecasting-Based Life Cycle Assessment Framework for Hydro-Dominated Grids

Energies
Rising global electricity demand and the expansion of distribution networks require a critical assessment of component-level greenhouse gas contributions.

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

Molecular 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.

Research on additional damping control strategy of flexible distribution transformer

Frontiers in Energy Research
Disturbances to the power system may lead to relative swing between synchronous generator rotors, causing low-frequency oscillation problems in the absence of damping.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

A simple stripline design for uneven power split [PDF]

A technique for the design of stripline or microstrip power dividers for unequal, but in-phase, power split is described. The output power ratio is determined by selecting the location of the input port in a manner analogous to the tap point for an ...

Distribution transformers market

Transformers Magazine, 2019
Global distribution transformers market reached around $5.5 billion in 2018 (up to 600 kVA and below 40 kV). The majority of this demand, around 74 %, came from distribution utilities globally, followed by 19 % from industry and around 7 % from power generation.

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Consistency Conditions: Efficiency Measures for the Electricity Distribution Sector in South America [PDF]

The main goals of this paper are basically two: to compare the relative efficiency of the firms in the electricity distribution sector in South America, and to perform a consistency analysis on the different approaches usually used to measure efficiency.
