A Carleman type theorem for proper holomorphic embeddings

, 1996
In 1927, Carleman showed that a continuous, complex-valued function on the real line can be approximated in the Whitney topology by an entire function restricted to the real line. In this paper, we prove a similar result for proper holomorphic embeddings.

Strongly pseudoconvex domains as subvarieties of complex manifolds

, 2009
In this paper (a sequel to B. Drinovec Drnovsek and F. Forstneric, Holomorphic curves in complex spaces, Duke Math. J. 139 (2007), 203-253) we obtain existence and approximation results for closed complex subvarieties that are normalized by strongly ...

Equivariant embeddings of strongly pseudoconvex CR manifolds

, 2020
Ich untersuche CR Mannigfaltigkeiten mit eigentlichen, transversalen Gruppenwirkungen. Zuerst zeige ich, dass sich solche Mannigfaltigkeiten immer äquivariant in eine komplexe Mannigfaltigkeit mit holomorpher Gruppenwirkung einbetten lassen. Dies nutze ich, um zu beweisen, dass der Quotient nach der Wirkung immer die Struktur eines komplexen Raumes ...

Reduced vascular leakage correlates with breast carcinoma T regulatory cell infiltration but not with metastatic propensity

Molecular Oncology, EarlyView.
A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Invariant Kohn-Rossi cohomology and obstruction to embedding of compact real (2n-1)-dimensional CR manifolds in CN

Journal of the Mathematical Society of Japan, 1996
Let \(X\) be a compact \(CR\) manifold of dimension \(2n - 1\), \(n \geq 3\) and \((H,J)\) be the holomorphic tangent bundle of \(x\). A smooth \(S^1\)-action on \(X\) is said to be transversal holomorphic if it preserves \(H\) and commutes with \(J\), and the vector field which generates the action is transversal to \(H\) at all points of \(X ...

Rheocasting versus Die Casting: An Insight into the Low‐Cycle Fatigue Behavior of AlSi7Mg0.6

Advanced Engineering Materials, EarlyView.
The study compares rheocast lightweight components with high‐pressure die cast materials regarding microstructure and fatigue behavior. Rheocast process offers higher efficiency due to lower casting temperatures. Despite some microstructural differences, both processes show similar strengths (yield strength 125 MPa, tensile strength 240 MPa).

Displacement energy of unit disk cotangent bundles

, 2013
We give an upper bound of a Hamiltonian displacement energy of a unit disk cotangent bundle $D^*M$ in a cotangent bundle $T^*M$, when the base manifold $M$ is an open Riemannian manifold.
