MicroRNA-551b expression profile in low and high-grade cervical intraepithelial neoplasia [PDF]

open access: yes, 2018
OBJECTIVE: To evaluate the expression of microRNA (miR)-551b in patients with low and high grade cervical intraepithelial neoplasia (CIN) and to find an association with high-risk Human Papillomavirus (HR-HPV) infection-related prognostic biomarkers ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Investigation on the Mechanical Properties of Functionally Graded Nickel and Aluminium Alloy by Molecular Dynamics Study [PDF]

open access: yesarXiv, 2020
Functionally graded materials (FGMs), have drawn considerable attention of the worldwide researchers and scientific community because of its unique mechanical, thermal and electrical properties which may be exploited by varying the compositions gradually over volume. This makes FGM multifunctional material (properties changing continuously in a certain

Prediction of interfacial area concentration based on interpretable neural network

open access: yesHe jishu
BackgroundInterfacial area concentration (IAC) is a key parameter of the interface transfer term in the closed two-fluid model of two-phase flow, which characterizes the strength of the gas-liquid interface transport capacity.

Long-Term Outcomes of Low-Achieving Third Grade Readers [PDF]

open access: yes, 2018
Research shows that students who demonstrate low reading achievement in 3rd grade have trouble catching back up to grade level and being successful in school, compared to their peers who demonstrate early proficiency (Fiester 2010; Hernandez 2011; Juel ...

A dynamic model for the optimization of oscillatory low grade heat engines [PDF]

open access: yes, 2011
The efficiency of a thermodynamic system is a key quantity on which its usefulness and wider application relies. This is especially true for a device that operates with marginal energy sources and close to ambient temperatures.
