Modifiable risk factors that mediate the effect of educational attainment on the risk of stroke: a network Mendelian randomization study

open access: yesMolecular Brain, 2023
Background Stroke is a common cerebrovascular disease with great danger to public health. Educational inequality is a universal issue that influences populations’ stroke risk.

On Effective Theory of Brane World with Small Tension [PDF]

open access: yes, 1999
The five dimensional theory compactified on $S^1$ with two ``branes'' (two domain walls) embedded in it is constructed, based on the field-theoretic mechanism to generate the ``brane''.

Secondary Data Analytics of Aquaporin Expression Levels in Glioblastoma Stem-Like Cells

open access: yesCancer Informatics, 2015
Glioblastoma is the most common brain tumor in adults in which recurrence has been attributed to the presence of cancer stem cells in a hypoxic microenvironment.

Risk Quantification and Analysis of Coupled Factors Based on the DEMATEL Model and a Bayesian Network

open access: yesApplied Sciences, 2019
With the developing of high integrations in large scale systems, such as aircraft and other industrial systems, there are new challenges in safety analysis due to the complexity of the mission process and the more complicated coupling characteristic of ...

Limit cycles for Singular Perturbation Problems via Inverse Integrating Factor

open access: yesBoletim da Sociedade Paranaense de Matemática, 2008
In this paper singularly perturbed vector fields X_{varepsilon} defined in R^2 are discussed. The main results use the solutions of the linear partial differential equation X_{varepslion}V = div(X_{varepslion})V to give conditions for the existence of limit cycles converging to a singular orbit with respect to the Hausdorff distance.

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 Change of Variables to the Dual and Factorization of Composite Anomalous Jacobians [PDF]

open access: yes, 1995
Changes of variables giving the dual model are constructed explicitly for sigma-models without isotropy. In particular, the jacobian is calculated to give the known results.

Existence of an inverse integrating factor, center problem and integrability of a class of nilpotent systems

open access: yesChaos, Solitons & Fractals, 2012
We characterize the nilpotent systems whose lowest degree quasi-homogeneous term is (y,σxn)T, σ=±1, having a formal inverse integrating factor. We prove that, for n even, the systems with formal inverse integrating factor are formally orbital equivalent to (x˙,y˙)T=(y,xn)T. In the case n odd, we give a formal normal form that characterizes them.

Adaptor protein CIN85 potentiates the motility of osteosarcoma cells via the Akt/mTOR and MMP2‐COL3A1 axis

open access: yesMolecular Oncology, EarlyView.
CIN85 is highly expressed in osteosarcoma, particularly in metastatic lesions. Its overexpression increases cell migration and Matrigel invasion, while silencing CIN85 suppresses these behaviors. Transcriptome analysis shows that CIN85 regulates MMP2, COL3A1, and Akt/mTOR signaling. Targeting these pathways reverses CIN85‐induced motility, highlighting
