Time Evolution in the External Field: the Unitarity Paradox

, 2000
One of the axioms of quantum field theory is the property of unitarity of the evolution operator. However, if one considers the quantum electrodynamics in the external field in the leading order of perturbation theory, one will find that the evolution ...

Crucial parameters for precise copy number variation detection in formalin‐fixed paraffin‐embedded solid cancer samples

Molecular Oncology, EarlyView.
This study shows that copy number variations (CNVs) can be reliably detected in formalin‐fixed paraffin‐embedded (FFPE) solid cancer samples using ultra‐low‐pass whole‐genome sequencing, provided that key (pre)‐analytical parameters are optimized.

Robust Iterative Interference Alignment for Cellular Networks with Limited Feedback

, 2014
In theory coordinated multi-point transmission (CoMP) promises vast gains in spectral efficiency. But industrial field trials show rather disappointing throughput gains, whereby the major limiting factor is proper sharing of channel state information ...

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 ...

Mixing Techniques: Between Technical Precision and Artistic Intent

Studia Universitatis Babeş-Bolyai. Musica
Mixing is a critical phase in music production, defining a track’s sonic character and commercial appeal. Engineers employ EQ, compression, saturation, reverb, and automation to shape the final sound, adapting techniques to each genre’s distinct ...

Interrogating the immune landscape of microsatellite stable RAS‐mutated colon cancer

Molecular Oncology, EarlyView.
COLOSSUS project RAS‐mutated MSS colon cancer study explored transcriptomics and immune cell density by immunohistochemistry (IHC), Immunoscore (IS), ISIC/TuLIS scores, mutation counts, and detected different prevalences but similar microenvironment composition across immune markers with clinical relevance for future immunotherapy combination ...

On the choice of beam polarization in $$e^+e^-\rightarrow ZZ/Z\gamma $$ e + e - → Z Z / Z γ and anomalous triple gauge-boson couplings

European Physical Journal C: Particles and Fields, 2017
The anomalous trilinear gauge couplings of Z and $$\gamma $$ γ are studied in $$e^+e^-\rightarrow ZZ/Z\gamma $$ e + e - → Z Z / Z γ with longitudinal beam polarizations using a complete set of polarization asymmetries for the Z boson.
