Flaxseed Oil Testing to Determine its Suitability as an Alternative to Transformer Oil [PDF]

E3S Web of Conferences
This study aims to assess the feasibility of using flaxseed oil as an alternative to transformer oil. Petroleum, a non-renewable resource with a negative environmental impact, is the basis of the transformer oil currently in use.

Tail Behavior of Regression Estimators and their Breakdown Points [PDF]

Econometrica, 1990
Following \textit{J. Jurečková} [Ann. Stat. 9, 578-585 (1981; Zbl 0476.62032), and Commentat. Math. Univ. Carol. 22, 365-375 (1981; Zbl 0466.62030)], this paper introduces a finite-sample measure of performance of regression estimators based on tail behaviour.

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.

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Comprehensive Definitions of Breakdown Points for Independent and Dependent Observations [PDF]

Journal of the Royal Statistical Society Series B: Statistical Methodology, 2003
SummaryWe provide a new definition of breakdown in finite samples, with an extension to asymptotic breakdown. Previous definitions centre on defining a critical region for either the parameter or the objective function. If for a particular outlier configuration the critical region is entered, breakdown is said to occur. In contrast with the traditional

TMC4 localizes to multiple taste cell types in the mouse taste papillae

FEBS Open Bio, EarlyView.
Transmembrane channel‐like 4 (TMC4), a voltage‐dependent chloride channel, plays a critical role in amiloride‐insensitive salty taste transduction. TMC4 is broadly expressed in all mature taste cell types, suggesting a possible involvement of multiple cell types in this pathway.

Down‐regulation of Shh in the hair follicles of mice during chemotherapy‐induced hair loss is mediated by the JAK/STAT1 signaling pathway

FEBS Open Bio, EarlyView.
We found that during chemotherapy‐induced alopecia (CIA), Sonic hedgehog (Shh) expression significantly decreased in hair follicle Shh+ cells, whereas the Janus‐activated kinase/signal transducer and activator of transcription 1 (JAK/STAT1) signaling pathway was markedly activated.

Percolating model of gas breakdown

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007
We consider the existing models of electrical breakdown. Using the theory of overflow to analyze the ionized overlap of gas space is suggested. The condition of spark breakdown of gas-discharge space for any field structure is defined based on the point ...
