Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Evaluation of Lightning Impulse Test by Frequency Response Analysis [PDF]

open access: yes, 2006
In this work are presented the basis for improving the interpretation of transformer lightning impulse test and the development of a graphical user interface system, which allows comparisons of time domain data and frequency response.

Improving Vision Transformers by Revisiting High-Frequency Components

open access: yes, 2022
The transformer models have shown promising effectiveness in dealing with various vision tasks. However, compared with training Convolutional Neural Network (CNN) models, training Vision Transformer (ViT) models is more difficult and relies on the large-scale training set.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Ferroresonant flux coupled battery charger [PDF]

open access: yes, 1987
A battery charger for incorporation into an electric-powered vehicle is disclosed. The charger includes a ferroresonant voltage-regulating circuit for providing an output voltage proportional to the frequency of an input AC voltage.

High-Frequency Lithium Acetate Transformation of Schizosaccharomyces pombe [PDF]

open access: yes, 2018
The introduction of ectopic DNA, such as plasmids, into yeast cells has for decades been a critical protocol for the study of this eukaryotic model system. We describe here an efficient transformation procedure for use in the fission yeast Schizosaccharomyces pombe.

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

open access: yesMolecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Coreless Planar Transformer using Low-Temperature Co-fired Ceramics for Isolated Gate Driver Applications [PDF]

open access: yes, 2015
The aim of this thesis project is to design a signal isolation transformer for gate driver applications using coreless planar transformers (CPT) on a low-temperature co-fired ceramic (LTCC) substrate.

Optimal passive filter design for effective utilization of cables and transformers under non-sinusoidal conditions [PDF]

open access: yes, 2014
Transformers and cables have overheating and reduced loading capabilities under non-sinusoidal conditions due to the fact that their losses increases with not only rms value but also frequency of the load current.
