On the existence of chaotic circumferential waves in spinning disks
, 2007 We use a third-order perturbation theory and Melnikov's method to prove the existence of chaos in spinning circular disks subject to a lateral point load.

Molecular Oncology, EarlyView.Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Backward- and forward-looking potential of anaphors
Frontiers in Psychology, 2015 Personal pronouns and demonstratives contribute differently to the encoding of information in the mental model and they serve distinct backward- and forward-looking functions.

BMC Public Health, 2023 Background Shift work has been related to adverse health outcomes that can partially be attributed to physical inactivity. However, our knowledge of the influence of shift work on physical activity and sedentary behavior is inconclusive.

The backward shift on weighted Bergman spaces.
Michigan Mathematical Journal, 1996 The authors study the backward shift-invariant subspaces of the weighted Bergman spaces \(A_\alpha^p\) for \(\alpha>-1\) and \(1\leq ...

Dynamic of Time Varying Weighted Backward Shift Operator
, 2023 we study the hypercyclic and chaotic properties of the time varying weighted backward shift operator $(Tx)(t)=w(t)x(t+a)$ in $L_p(0,\infty)(1\leq p<\infty)$ and $C_0[0,\infty)$. And we also analyse the spectral structure of the operators if the spaces are complex.

Backward shift invariant subspaces in the bidisc [PDF]
Hokkaido Mathematical Journal, 2004 Suppose that \(T_{\varphi}\) is a Toeplitz operator with symbol \(\varphi\) on the Hardy space \(H^{2}\) on the bidisc \(T^{2}\). Let \(N\) be a backward shift invariant subspace of \(H^{2}(T^{2})\), that is, \(N\) is invariant under \(T_{z}^{\ast}\) and \(T_{w}^{\ast}\), where \(z\) and \(w\) are the coordinate functions of the point of \(T^{2}\). Let

Similarity of Operators in the Bergman Space Setting
, 2012 We give a necessary and sufficient condition for an n-hypercontraction to be similar to the backward shift operator in a weighted Bergman space. This characterization serves as a generalization of the description given in the Hardy space setting, where ...

Dual targeting of RET and SRC synergizes in RET fusion‐positive cancer cells
Molecular Oncology, EarlyView.Despite the strong activity of selective RET tyrosine kinase inhibitors (TKIs), resistance of RET fusion‐positive (RET+) lung cancer and thyroid cancer frequently occurs and is mainly driven by RET‐independent bypass mechanisms. Son et al. show that SRC TKIs significantly inhibit PAK and AKT survival signaling and enhance the efficacy of RET TKIs in ...

Observation of Goos-H\"{a}nchen shifts in metallic reflection
, 2007 We report the first observation of the Goos-H$\rm \ddot{\textbf{a}}$nchen shift of a light beam incident on a metal surface. This phenomenon is particularly interesting because the Goos-H$\rm \ddot{\textbf{a}}$nchen shift for $p$ polarized light in ...
