Spectroscopic indications of tunnel barrier charging as the switching mechanism in memristive devices [PDF]

open access: yes, 2017
Resistive random access memory is a promising, energy-efficient, low-power “storage class memory” technology that has the potential to replace both flash storage and on-chip dynamic memory.

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

open access: yesMolecular Oncology, EarlyView.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

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

open access: yesMolecular 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 ...

Analysis of Switching-Loss-Reduction Methods for MHz-Switching Buck Converters [PDF]

open access: yes2007 IEEE Conference on Electron Devices and Solid-State Circuits, 2007
Numbers of switching-loss-reduction methods recently proposed for MHz-switching buck converters are thoroughly investigated. From a theoretical perspective, switching loss is found to be effectively minimized by adapting the width rather than the turn-on voltage of power transistors of a buck converter.

Relabelling Algorithms for Large Dataset Mixture Models [PDF]

open access: yes, 2014
Mixture models are flexible tools in density estimation and classification problems. Bayesian estimation of such models typically relies on sampling from the posterior distribution using Markov chain Monte Carlo.

RIPK4 function interferes with melanoma cell adhesion and metastasis

open access: yesMolecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Dual-Transformer Series Resonant Converter with Full Range ZVS Operation

open access: yesShanghai Jiaotong Daxue xuebao
A dual-transformer series resonant converter (DTSRC) is proposed to solve the problem of excessive return power and loss of zero voltage switching (ZVS) operation under light load in the dual bridge resonant converter (DBRC). A dual-transformer structure

Low-loss AlInN/GaN microwave switch

open access: yesElectronics Letters, 2011
A report is presented on the first low-loss monolithic microwave integrated circuit switch using AlInN/GaN heterostructure field effect transistors. Owing to significantly lower sheet resistance compared to the conventional AlGaN/GaN heterostructure (215 against 280 Q/□), and lower contact resistance (0.27 against 0.5 Ω×mm), the microwave switch based ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular 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 ...

Loss Jump During Loss Switch in Solving PDEs with Neural Networks

open access: yesCommunications in Computational Physics
Using neural networks to solve partial differential equations (PDEs) is gaining popularity as an alternative approach in the scientific computing community. Neural networks can integrate different types of information into the loss function. These include observation data, governing equations, and variational forms, etc.
