Face antispoofing has now attracted intensive attention, aiming to assure the reliability of face biometrics. We notice that currently most databases focus on data with little variations, which may limit generalization performance trained models since potential attacks in real world are probably more complex. In this paper we release a database covers diverse range attack variations. Specifically, contains 50 genuine subjects, and fake faces made from high quality records faces. Three...
Existing face liveness detection algorithms adopt behavioural challenge-response methods that require user cooperation. To be verified live, users are expected to obey some unfriendly requirement. In this paper, we present a multispectral method, which is cooperation free. Moreover, the system adaptive various user-system distances. Using Lambertian model, analyze properties of human skin versus non-skin, and discriminative wavelengths then chosen. Reflectance data genuine fake faces at...
Liveness detection is an indispensable guarantee for reliable face recognition, which has recently received enormous attention. In this paper we propose three scenic clues, are non-rigid motion, face-background consistency and imaging banding effect, to conduct accurate efficient liveness detection. Non-rigid motion clue indicates the facial motions that a genuine can exhibit such as blinking, low rank matrix decomposition based image alignment approach designed extract motion....
An enhanced spectral response was realized in an AlGaN-based solar-blind ultraviolet (SB-UV) detector using aluminum (Al) nanoparticles (NPs) of 20-60 nm. The peak responsivity the (about 288 nm) with 60 nm Al NPs is more than two times greater that a without under 5-V bias, reaching 0.288 A/W. To confirm enhancement mechanism NPs, extinction spectra were simulated time-domain and frequency-domain finite-element methods. calculation results show dipole surface plasmon resonance wavelength...
Background: Williams-Beuren syndrome (WBS) is a rare genetic with characteristic “elfin” facial gestalt. The characteristics include broad forehead, periorbital puffiness, flat nasal bridge, short upturned nose, wide mouth, thick lips, and pointed chin. Recently, deep convolutional neural networks (CNNs) have been successfully applied to recognition for diagnosing syndromes. However, there little research on WBS using CNNs. Objective: purpose of this study was construct an automatic model...
Although state-of-the-art (SOTA) SAT solvers based on conflict-driven clause learning (CDCL) have achieved remarkable engineering success, their sequential nature limits the parallelism that may be extracted for acceleration platforms such as graphics processing unit (GPU). In this work, we propose FastFourierSAT, a highly parallel hybrid solver gradient-driven continuous local search (CLS). This is by algorithm inspired fast Fourier transform (FFT)-based convolution computing elementary...
Depth-First Search (DFS), which traverses a graph in the depth- first order, is one of fundamental operations, and result DFS over all nodes G spanning tree known as DFS-Tree. There are many algorithms that need such connected component computation, topological sort, community detection, eulerian path bipartiteness testing, planar etc, because in-memory algorithm shows it can be done linear time w.r.t. size G. However, given fact real-world graphs grow rapidly big data era, cannot used to...
Toxoplasmosis caused by infection with Toxoplasma gondii is an important parasitic zoonosis a worldwide distribution. In this study, we examined the functions of two thioredoxins (namely CTrp26 and CTrx1) T. tachyzoites generation HA tag strains or gene deficient parasites in Type I RH strain (ToxoDB#10). Immunofluorescence analysis (IFA) was used to investigate subcellular localization (Trxs). Results IFA showed that both CTrx1 were located cytoplasm . Functional characterizations...
For portable devices with limited resources, it is often difficult to deploy deep networks due the prohibitive computational overhead. Numerous approaches have been proposed quantize weights and/or activations speed up inference. Loss-aware quantization has directly formulate impact of weight on model's final loss. However, we discover that, under certain circumstances, such a method may not converge and end oscillating. To tackle this issue, introduce novel loss-aware algorithm efficiently...
Although radiotherapy is a general oncology treatment and often synergistically applied with surgery chemotherapy, it can cause side effects during after treatment. Gold nanoparticles were studied as potential material to enhance radiation induce damage in cancer cells. However, few studies have been conducted examine the of gold nanofilm on cell impairment under X-ray This paper describes microfabrication-based single-cell array platform evaluate DNA induced by enhanced patches (GNFPs)....
Abstract Background Forage production is the fundamental ecosystem service of grasslands. Although forage consumption occurs at community level, most studies focused on species-level changes quality. The quantitative and qualitative are driven by species-specific trait, intra-specific plasticity, species turnover. We examined in digestibility after 5-year factorial treatments nitrogen (N) addition mowing a temperate steppe linked such to assembly under Price equation framework. Results...
Toxoplasmosis caused by Toxoplasma gondii is an important zoonosis of human and animal health significance. Current chemical therapeutics have side effects, no commercially available vaccine licensed for the prevention toxoplasmosis in humans most animals. Developing a safe effective with long-term protection against T. infection necessary to control toxoplasmosis. HAD2a key member haloacid dehalogenase (HAD) phosphatase family, which essential daughter budding. However, role virulence...
Traditional garden design is considered as the main course of landscape architecture. Through teaching reform this course, students can learn principles and methods combine classroom theoretical with practical teaching. In view characteristics application-oriented universities, paper improves quality traditional architecture through discussion-based method.
The implantable brain-computer interface has been widely used in recent years due to its great application potential and research value. Few neural implants have designed gather spikes, which require a higher sampling frequency than ECoG LFPs. These systems are still constrained by low channel counts their bulky size. Furthermore, wire connection is many interfaces for further data analysis, facing challenges such as tissue infection, limited movement, increased noise interference. To...
Shadow as a design element applied to architectural and landscape design, can embellish, foil, even enhance the subject. The shadow also make works full of vitality characteristic. Based on actual cases, this article analyses effect architecture landscape, reveals special producing by shadow. effects include breaking visual limitation, enhancing connotation artistic conception design. give people an unexpected appeal spiritual shock. And bring much richer experience more deep thinking people.
