We study the phase diagram of director structures in cholesteric liquid crystals negative dielectric anisotropy homeotropic cells thickness d which is smaller than pitch p. The basic control parameters are frustration ratio d/p and applied voltage U. Fluorescence Confocal Polarising Microscopy allows us to directly unambiguously determine 3-D structures. results importance for potential applications structures, such as switchable gratings eyewear with tunable transparency based.
Therapeutic agents that target both tumor cell and vascular endothelial may achieve additional anti-tumor efficacy, particularly in lung cancer due to the critical roles of angiogenesis during progression metastasis. In this work, we showed pitavastatin, a novel cholesterol-lowering drug, potently inhibited cells angiogenesis. This was achieved by induction apoptosis inhibition proliferation human tumor-associated cell. Pitavastatin not only effective chemo-sensitive but also chemo-resistant...
A combination of analytical, numerical, and qualitative methods is used to study competing equilibrium orientational configurations in a liquid-crystal thin film. The material cholesteric liquid crystal has negative dielectric anisotropy. system strong homeotropic anchoring the director on confining substrates subject voltage applied across film thickness. free-energy functional embodies influences boundary conditions, intrinsic chirality material, electric field. Attention restricted fields...
Scale-invariant feature transform (SIFT) algorithm, one of the most famous and popular interest point detectors, detects extrema by using difference-of-Gaussian (DoG) filter which is an approximation to Laplacian-of-Gaussian (LoG) for improving speed. However, DoG has a strong response along edge, even if location edge poorly determined therefore unstable small amounts noise. In this paper, we propose novel detection scale space Laplacian-of-Bilateral (LoB) filter. The LoB filter, produced...
Human pose estimation is an essential task in computer vision, applied motion recognition, capture, augmented reality, etc. The emergence of Lite HRNet balances computational complexity with high precision, using channel attention mechanism instead complex convolution while maintaining resolution, thus possessing less computation and higher precision. use the results loss position information that crucial to generating spatially selective maps. Accordingly, this paper, we implement improved...
Internet of things realize the intellectual identification, location tracking monitoring and management according to a certain protocol.. This paper reviews characteristic internet firstly, then analysis fingerprint recognition matching algorithm identification. Put forward an improving authentication on based identification enhance security things.
To study the effects of continuous ultrasonic phacoemulsification performed with and without an anterior chamber maintainer (ACM) on corneal endothelial damage in patients hard nuclear cataract.Sixty eyes 60 cataract (grade IV), one lesion per eye, were randomly allocated into 2 groups: (group A) or B) ACM. The intraoperative accumulated energy complex parameter (AECP), frequency shallow chamber, postoperative incision edema, cell counts, visual recovery compared between groups.The AECP,...
Type-A aortic dissection (TAAD) is common life-threatening cardiovascular diseases with high-morbidity and mortality but the concrete etiology of disease remains unclear, which might disturb or delay early diagnosis for TAAD. Anoikis a special form programmed cell-death (PCD) induced by detachment anchorage-dependent cells from extracellular matrix (ECM) neighboring cells, has been widely applied to identify anoikis-related biomarkers prediction prognosis in oncological fields. However,...
With the development of wireless communication technology, video over mobile ad hoc networks has been more and applied.How to ensure QoS is an important problem that should be solved quickly.In this paper, we propose a routing algorithm for Video Streaming in MANET.The introduces multi-constrained mechanisms, optimizes paths through bandwidth, delay, service priorities congestion degree constraints.The simulation results show that, medium speed or low-speed MANET where nodes are...
As a promising biometrics, ear recognition is attracting increasing research interests among researchers in recent years. It has wide range of civilian and law-enforcement applications. In this paper, new feature extraction approach investigated for by using scale information multi-scale Gabor filters. Compared with augmented features defined via concatenation the filtering coefficients, proposed will not only avoid too much redundancy but also tend to extract more precise structural...
The complex geological drilling process is full of uncertain factors because the invisibility bottom hole. cause problems trajectory control and condition monitoring. In order to solve these problems, an intelligent system designed for by taking XD-35DB electric-drive rig as a study case. At first, hardware structure described in detail, working mechanism analyzed. Then, based on its mechanism, designed, which includes basic automation layer layer. from three aspects: optimization...
Human abnormal action recognition is crucial for video understanding and intelligent surveillance. However, the scarcity of labeled data human actions often hinders development high‐performance models. Inspired by multimodal approach, this paper proposes a novel approach that leverages text descriptions associated with videos. Our method exploits correlation between domain in semantic feature space introduces heterogeneous transfer learning framework from to domain. The videos used encoding...
