Abstract Dielectric polymers for electrostatic energy storage suffer from low density and poor efficiency at elevated temperatures, which constrains their use in the harsh-environment electronic devices, circuits, systems. Although incorporating insulating, inorganic nanostructures into dielectric promotes temperature capability, scalable fabrication of high-quality nanocomposite films remains a formidable challenge. Here, we report an all-organic composite comprising blended with...
Abstract High‐temperature capability is critical for polymer dielectrics in the next‐generation capacitors demanded harsh‐environment electronics and electrical‐power applications. It well recognized that energy‐storage capabilities of are degraded drastically with increasing temperature due to exponential increase conduction loss. Here, a general scalable method enable significant improvement high‐temperature capacitive performance current reported. The properties terms discharged energy...
Initiation of new subduction zones is an integral part Earth's plate tectonics regime. It generally accepted that the negative buoyancy sufficiently old oceanic lithosphere provides primary driving force for initiation. However, dynamic processes initiation are still debated. In this paper, we summarize representative geological records initiation, including supra-subduction zone (SSZ) ophiolitic mélanges, forearc basalts and metamorphic soles, review four typical mechanisms using natural...
We report here on one-dimensional (1D) grating couplers based hybrid silicon/LNOI platform for polarization-independent and high-efficient single-polarization coupling efficiencies. A low index oxide buffer layer was introduced in between the top silicon high coupler bottom LNOI waveguide. With optimal design of thicknesses, modal matches can be tuned either single polarization or both TE/TM applications. Over 70% efficiency achieved basic uniform 1D without any reflectors incorporated....
Integrated Gate Commutated Thyristor (IGCT) gate driver unit (GDU) is the key hub of secondary control systems and primary high-voltage high-current power devices. However, utilization discrete devices in design presents several drawbacks, including numerous components, limited electromagnetic immunity, reduced reliability, increased consumption. Consequently, trend towards chipization advancement IGCT drive technology deemed inevitable. Due to high level integration required for...
<title>Abstract</title> Lung cancer is a primary malignant tumor of the lung that poses greatest health risk to population. An immune-associated protein family gene called T-cell immunoglobulin and mucin domain 1 (TIM-1) can be utilized as an immunological marker help diagnose cancer. However, correlation between TIM-1 polymorphisms has not been reported, so present study focused on genotyping polymorphic loci (rs1501909, rs2036402, rs2270924, rs870581) by TaqMan probe assay, aim was...
ABSTRACT The precursor composed of phytic acid (PA) and sodium alginate (SA) was fabricated using the sol–gel technique subsequently applied as a coating on surface rigid polyurethane foam (RPUF). PA/SA aerogel obtained freeze‐drying technology to enhance fire resistance flame‐retardant properties RPUF. Subsequent testing revealed that 0.5 mm thick effectively enhances flame retardancy composite. Limiting oxygen index (LOI) composites stands at an impressive 30.4 vol%, it attains V‐0 rating...
High altitude polycythemia (HAPC) is a disease with high morbidity and great harm in populations. It has been shown that Single Nucleotide Polymorphisms (SNPs) correlate the genetic basis of adaptation to plateau hypoxia Tibetan The EPAS1 PPARA genes are involved by encoding transcription factors populations at altitude. aim this study was investigate association gene locus polymorphisms susceptibility HAPC Chinese population. We included 78 patients 84 healthy controls, genotyped SNP loci...
In this paper, the electric-field distribution around composite insulators and heads of transmission towers is calculated by a model coupling indirect boundary-element method to moment method. The heterogeneous media, such as filament metal structures lines, are considered altogether. can take into account not only permittivity but also resistivity media using complex in frequency domain. three-phase 330-kV tower with was analyzed. electric fields on surfaces grading rings phase...
Conventional frequency preshift technology cannot distinguish between the large Doppler shift and offset aroused by crystal oscillator, which significantly hinders system performance improvement in high mobility environments when is present. In this paper, a joint estimation algorithm environment based on orthogonal angle domain subspace projection proposed, can track fast time-varying separate from offset. First, an proposed to project spread caused into equivalent shifts each subspace....
The transient near-field of the electrostatic discharge (ESD) is strongly affected by current waveform. After analyzing several typical mathematical descriptions ESD for contact mode, two new were constructed according to polynomial pulse function. These have continuity first derivative at t=0 and are time-integrable. They proved little relative error compared IEC61000-4-2 standard.
The evaluation of the lightning shielding failure a transmission line is very important in power system design, and operation voltage has rarely been considered before. However, when reaches 800 kV tower height near 100 m, influence may not be ignored. In this paper, an experimental consisting air gap between plate/rod conductor was established, where dc could applied to accompanied by negative impulse on electrode. An upward leader up 1.54 m length observed, velocity charge density were...
Seamount chains (oceanic plateaus, submarine ridges) are unique morphologic features on the seafloor, which resulted from motion of lithosphere over a convective plume. being carried along by plate motions, eventually subducted beneath continental/oceanic plates or accreted in accretionary complex, thus causing series effects convergent margin. In this paper, we briefly review distribution and typical modern seamount chains, including Hawaiian‐Emperor Louisville Cocos, Ninetyeast Caroline...
