The Pixogram: Addressing High Payload Demands for Video Steganography

open access: yesIEEE Access, 2019
This paper introduces the concept of a pixogram which makes possible a fresh approach to high payload video steganography. The pixogram allows for a new perspective by investigating the temporal changes that take place at the individual pixel level ...

Exploring the spatio-temporal correlation of twin photons via sum frequency generation

open access: yes, 2011
We describe the X-shaped geometry, non-factorable in space and time, of the spatio-temporal correlation of biphotons and the temporal localization thereby achievable.

Spatio-Temporal Unequal Interval Correlation-Aware Self-Attention Network for Next POI Recommendation

open access: yes, 2022
As the core of location-based social networks (LBSNs), the main task of next point-of-interest (POI) recommendation is to predict the next possible POI through the context information from users’ historical check-in trajectories.

Preoperative circulating tumor cells integrated with imaging analysis for prognostic evaluation in head and neck squamous cell carcinoma

open access: yesMolecular Oncology, EarlyView.
Detecting circulating tumor cells (CTCs) in blood before surgery may help predict outcomes in patients with head and neck squamous cell carcinoma (HNSCC). Here, we show when combined with tumor size and lymph node involvement from routine imaging, CTC status identifies high‐risk patients with poorer survival—offering a simple, minimally invasive tool ...

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

open access: yesMolecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Analysis of amplitude statistical and correlation characteristics of high grazing angle sea-clutter

open access: yesThe Journal of Engineering, 2019
Research on the characteristics of sea clutter has always been the focus in the problem of sea target detection as an indispensable part. In recent years, the problem of sea clutter characteristics under medium-high grazing angle is also paid more and ...

What are temporal correlations

open access: yes, 2019
Space and time are crucial twins in physics. In quantum mechanics, spatial correlations already reveal nonclassical features, such as entanglement, and have bred many quantum technologies. However, the nature of quantum temporal correlations still remains in vague.

Temporal response of nonequilibrium correlated electrons [PDF]

open access: yesComputer Physics Communications, 2011
In this work we examine the time-resolved, instantaneous current response for the spinless Falicov-Kimball model at half-filling, on both sides of the Mott-Hubbard metal-insulator transition, driven by a strong electric field pump pulse. The results are obtained using an exact, nonequilibrium, many-body impurity solution specifically designed to treat ...

Gut microbiota alterations in patients with non‐small‐cell lung cancer undergoing chemoradiotherapy

open access: yesMolecular Oncology, EarlyView.
We investigated the impact of concurrent chemoradiotherapy (CRT) on the gut microbiota in patients with locally advanced non‐small‐cell lung cancer. Overall gut microbiota composition remained largely stable throughout CRT while antibiotic exposure may influence microbial diversity.
