Using Modeling and Simulation to Study the Influence of TiO2 Shape on the Dielectric Properties of TiO2/PVDF Composite

open access: yesJournal of Harbin University of Science and Technology, 2022
TiO2/PVDF composite materials have excellent high dielectric properties and have wide application prospects in the fields of high voltage and energy storage insulation.In this paper, the finite element method was used to simulate the structure and ...

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 ...

Breakdowns [PDF]

open access: yesSSRN Electronic Journal, 2012
We study a continuous-time game of strategic experimentation in which the players try to assess the failure rate of some new equipment or technology. Breakdowns occur at the jump times of a Poisson process whose unknown intensity is either high or low.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

open access: yesMolecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

The Breakdown of Authority [PDF]

open access: yes, 2004
This paper studies organizations with autocratic decisionmaking, i.e., where superiors make the decisions and subordinates either defy or submit to the authority. Superiors differ in the degree to which they fear defiance. The superiors who need obedience most face a credibility problem, which, in fact, makes them the least likely to be obeyed.

THE EVOLUTION AND BREAKDOWN OF TRISTYLY [PDF]

open access: yesEvolution, 1979
In a tristylic species three types of individuals, distinguished by their flower morphology, occur. One form has a long style, while the anthers are in two whorls, one very low down, and one about half way between the stigma and the low anther whorl. The three positions of the sex organs in this form (called long or L) define three positions that can ...

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

open access: yesMolecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

Space charge and its impact on DC breakdown of polymeric materials

open access: yes, 2013
The presence of space charge will lead to distortion of electric field distribution within the dielectric material, resulting electric field enhancement in certain region of the dielectric. The electric field enhancement could cause material degradation,
