In this paper, one improved wide-band Schiffman phase shifter is presented by modifying the ground plane underneath coupled lines. new design, with under lines removed, even-mode impedance will be increased substantially. Meanwhile, we propose that additional isolated rectangular conductor placed to act as capacitor so odd-mode decreased. The proposed design was simulated full-wave electromagnetic software IE3D and validated measurement. Compared cascading microstrip multisection...
The anticipated 1000-fold increase in mobile data traffic over the next decade and explosion of new services applications pose great challenges for current orthogonal multiple access (OMA)-based 4G systems. A promising solution to address these is shift from currently predominant OMA non-orthogonal (NOMA). This article first introduces principle complexity-constrained capacity-achieving NOMA design. Then a pattern division (PDMA) scheme proposed meet exponentially growing demand users...
A new wide-band microstrip balun implemented on a single-layer printed circuit board (PCB) is presented in this letter. The proposed planar consists of Wilkinson power divider and noncoupled-line broad-band 180/spl deg/ phase shifter. To demonstrate the design methodology, one prototype realized. was simulated validated by measurement. Measured results show that 10-dB return loss unbalanced port has been achieved across bandwidth from 1.7 GHz to 3.3 GHz, or 64%. Within operation band,...
<p>Artificial intelligence (AI) is driving transformative changes in the field of medicine, with its successful application relying on accurate data and rigorous quality standards. By integrating clinical information, pathology, medical imaging, physiological signals, omics data, AI significantly enhances precision research into disease mechanisms patient prognoses. technologies also demonstrate exceptional potential drug development, surgical automation, brain-computer interface (BCI)...
Abstract Wheat bran is the processing byproduct of wheat, which thought to have great potential applications. To make a full utilization resource, this study investigated effects steam explosion (SE) modification, with intensity at 1.0 MPa 20, 60, 100, 140, 180, and 220 s, respectively, on wheat soluble dietary fiber (SDF) content, physical‐chemical quality, antioxidant capacity, intestinal microbial spectrum. The impact long‐term intake WB100 (wheat modified under SE conditions 100 s)...
A broadband planar balun is presented in this work that makes use of a substrate integrated waveguide (SIW) technique using printed circuit board process. The proposed structure able to operate at millimeter wave frequencies and it does not require any tight line coupling sections as frequently used monolithic microwave design. In addition, can be with other topologies including nonplanar circuits made the same for achieving high efficiency. This consists 3 dB SIW power divider microstrip...
High penetration of renewable energycauses fluctuationsof power flow and results in system frequency fluctuation, which significantlyaffects the operation. The situation microgrid (MG) is worse because low inertia small time constant system. This paper present a novel use ofthesuperconducting magnetic energy storage (SMES) battery hybrid with function control MG.A management strategy for SMES used to achieve, firstly, faster primary frequencycontroland secondly, an improvement service time.
A broadband H-plane Wilkinson power divider that makes use of the half-mode substrate integrated waveguide (HMSIW) technique is presented in this work for first time. This utilizes structure SIWs such overall size largely reduced at least by half. In addition, lossy network or resistor branch with SIW order to obtain good output matching and isolation if unbalanced signals are combined divided. The proposed concept then validated theoretical analysis measurements. Good input return loss (S...
Changes in mitochondrial morphology and function play an important role secondary damage after acute spinal cord injury. We recorded the time representation of rats with Results showed that mitochondria had irregular shape, increased size. Mitochondrial cristae were disordered membrane rupture was visible at 2-24 hours Fusion protein mitofusin 1 expression gradually increased, peaked 8 injury, then decreased to its lowest level 24 hours. Expression dynamin-related 1, amitochondrial fission...
Acute liver failure (ALF) is a severe life-threatening disease associated with the disorder of gut-liver axis. However, cellular characteristics ALF in gut and related therapeutic targets remain unexplored. Here, we utilized D-GALN/LPS (D/L)-induced model to characterize 33,216 single-cell transcriptomes define mouse intestinal atlas. We found that unique, previously uncharacterized immune cells, including T B macrophages, neutrophils, are responsive ALF, identified transcriptional profiles...
Based on the known binary sequence sets and Gray mapping, a new method for constructing quaternary is presented resulting sets' properties are investigated. As three direct applications of proposed method, when we choose aperiodic, periodic, Z-complementary as sets, resultant respectively. In comparison with by Jang et al., can cope either both aperiodic periodic cases or even odd lengths sub-sequences, whereas former only fit case length sub-sequences. consequence, our al.'s methods, an...
In this letter, we present a family of 16-QAM periodic complementary sequences (PCSs), including three constructions. Our basic idea is to transform the known quaternary PCSs/GCSs (Golay sequences) into required ones. order guarantee that such transformation every construction successful, own sufficient conditions constructions are derived, respectively. methods can provide quite rich PCSs, whose main parameters up period 50 and number 12 sub-sequences given in Table 1, from large available...
This letter presents three methods that can transform ternary complementary sequence sets (CSSs) into 8-QAM+ CSSs. Method 1 yields CSSs with sequences of even length. 2 works for an arbitrary period, but results in a size twice the sets. 3 transforms odd periods CSSs, double period. The resultant be applied to signal processing, channel estimation, and synchronization.
In contemporary communications, Golay, periodic and Z- complementary sequence sets play a very important role, since such possess impulse-like or zero correlation zone (ZCZ) autocorrelation. On the other hand, advantages of signals over quadrature amplitude modulation (QAM) constellation are more prominent. Hence, design QAM has turned into one all-important issues in communications. Therefore, construction methods 16-QAM investigated, this letter, our goals arrived at by known quaternary...
