We aim to address the problem of Natural Language Video Localization (NLVL) — localizing video segment corresponding a natural language description in long and untrimmed video. State-of-the-art NLVL methods are almost one-stage fashion, which can be typically grouped into two categories: 1) anchor-based approach: it first pre-defines series candidates (e.g., by sliding window), then does classification for each candidate; 2) anchor-free directly predicts probabilities frame as boundary or...
This study was conducted to investigate the effects and mechanisms of all-trans lycopene on intestinal health by establishing lipopolysaccharide-induced (LPS-induced) jejunal inflammation model. Dietary supplementation enhanced serum jejunum antioxidant capacity. Lycopene significantly reduced LPS-induced upregulation toll-like receptor-4 (TLR-4) nuclear factor kappa-B (NF-κB), suggesting that activation TLR-4/NF-κB signaling pathway induced LPS challenge, further protected mice from...
Many nonprecious metal-selenide-based materials have been reported as electrocatalysts with high activity for the oxygen evolution reaction (OER). Herein, a hybrid catalyst film composed of Cu2Se and Cu2O nanoparticles directly grown on Ti foil (Cu2Se-Cu2O/TF) was prepared through simple fast cathodic electrodeposition method. Surprisingly, this electrode required relatively low overpotential 465 mV to achieve catalytic current density 10 mA cm-2 OER in 0.2 M carbonate buffer (pH = 11.0)....
Wavefront coding (WFC) techniques, including optical and digital image processing stages, enable significant capabilities for extending the depth of field imaging systems. In this study, we demonstrated a deeply learned far-infrared WFC camera with an extended field. We designed optimized high-order polynomial phase mask by genetic algorithm, exhibiting higher defocus consistency modulated transfer functions than works published previously. Additionally, trained generative adversarial...
While encryption technology safeguards the security of network communications, malicious traffic also uses protocols to obscure its behavior.To address issues traditional machine learning methods relying on expert experience and insufficient representation capabilities existing deep for encrypted traffic, we propose an classification method that integrates global semantic features with local spatiotemporal features, called BERT-based Spatio-Temporal Features Network (BSTFNet).At packet-level...
Infrared deflectometry is an efficient and accurate measuring method for curved surfaces fabricated via grinding or finish milling. The emitting properties geometrical configurations of the infrared light source a core component governing measurement performance.

Additionally, can be applied as calibration board calibrating...
Abstract The 2D material rhenium selenide (ReSe 2 ) has attracted significant interest due to its p‐type transport properties and anisotropic lattice structure. Its uniquely narrow bandgap of 0.9–1 eV enables efficient near‐infrared (NIR) detection. However, the growth large‐area ReSe mostly faces challenges such as high cost precursors reaction temperatures incompatible with back‐end‐of‐line (BEOL) processes. This work demonstrates an low‐cost method grow monolayer at significantly low...

We report simple effective supramolecular DS‐PECs introducing PMMA as support material catalyst modified with long carbon chains photoanodes. combination allow better immobilize the catalyst. obtained by this have display excellent photoactivities stabilities. A photocurrent density of 1.1 mA cm −2 maximum IPCE 9.5 % been 0.2 V vs NHE...
As network infrastructures continue to grow and traffic encryption technologies evolve at a rapid pace, the task of classifying encrypted has become significantly more intricate. These emerging methods render conventional approaches ineffectual in discerning types, consequently posing novel challenges security administration. Evidently, classification techniques are inadequate when it comes traffic. Consequently, researchers have turned machine learning deep models address this challenge,...
The phase measuring deflectometry is a powerful method for complex optical surfaces, which captures the reflected fringe images associated with displaying screen and calculates normal vectors of surface under test (SUT) accordingly. captured are usually set conjugate to SUT, in turn makes defocused. As result, blurring effect caused by point spread function (PSF) off-axis catadioptric imaging system can bias solved phases. In order correct errors, light field constructed based on Fourier...

A novel carrier sensing method with self-cancelation of the inter-carrier emission inevitably existent in OFDMA-based coexisting systems is proposed. Different from conventional energy-based detector, which directly compares energy some predefined thresholds without considering such emissions, our proposed can remove them before making decision, thus significantly reduces false-alarm probability and provides more access opportunities. Firstly, detection model presented, then distribution...
