Computation of the Unique Normal Form for Nonlinear Dynamical Systems in the Mechanical Applications
DEStech Transactions on Engineering and Technology Research, 2017 In the mechanical applications, research for degenerate bifurcations is usually connected with the normal form theory of nonlinear dynamical systems. In this paper, we mainly concern with the unique normal form for a class of three dimensional vector fields by the method of transformation with parameters. With the aid of the Maple software, a recursive

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 ...

To Prof. Floris Takens, who is doing so many things
, 2008 Dynamical systems play an important role in understanding many problems in science. The variety of difficulties that they present to the dynamicist is huge.

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.

The scanning normal form of linear dynamical systems with variable coefficients
Mathematical and Computer Modelling, 1990 Consider the system \(\dot x=A(t)x,\quad x\in {\mathbb{R}}^ n.\) In the neighbourhood of some \(\tau_ 0\) this system can be written as \(\dot x=(A(\tau_ 0)+\epsilon \gamma (\tau_ 0,\tau))x.\) A change of variables is found in order to give this system the form \(\dot y=B(\tau_ 0,\tau,\epsilon)y,\) where only certain items of B depend on \(\tau\). This

Molecular Oncology, EarlyView.We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Specific impairments in cognitive development: a dynamical systems approach
, 2008 Neuropsychologists have frequently proposed that domain-specific deficits can be observed in developmental disorders (e.g., phonology in dyslexia, theory of mind in autism, grammar in specific language impairment, face recognition in prosopagnosia ...

Molecular Oncology, EarlyView.In the present work, we have identified a transcriptional signature based on the differential expression of six genes (BCL2&MAST4, HSH2D&LAT2, METRN&PITPNM2) that would facilitate the early detection of T‐cell acute lymphoblastic leukemia (T‐ALL) patients prone to a poor treatment response and could be implemented at diagnosis, along with other risk ...

Numerical continuation of canard orbits in slow-fast dynamical systems
, 2009 A trajectory of a system with two clearly separated time scales generally consists of fast segments (or jumps) followed by slow segments where the trajectory follows an attracting part of a slow manifold. The switch back to fast dynamics typically occurs
