Instead of successive interference cancellation (SIC) for uplink non-orthogonal multiple access systems with fixed decoding order based on the statistical channel state information (CSI), we focus dynamic according to instantaneous CSI. After modeling fluctuation all users different transmit powers and path losses, a SIC receiver is proposed received power users. The outage probability system theoretically analyzed closed-form expressions three-user are derived. Simulations performed...
A field-circuit-coupled parameter adaptive modeling method for a permanent magnet synchronous motor is proposed in this paper. The model combines the merits of mathematical and magnetic field model. It takes into consideration saturation, current harmonics, cross coupling, eddy current, hysteresis loss effect terms corresponding parameters obtained from JMAG-finite element analysis (JMAG-FEA) tool To validate effectiveness model, three methods are comparatively studied through an offline...
In this paper, ZnO nanoflowers (NFs) were fabricated by thermal decomposition in an organic solvent and their application gas sensors photocatalysis was investigated. These single crystal NFs, which observed for the first time, with average size of ∼60 nm grown along {100} facet. It suggested that oleylamine used synthesis inhibited growth agglomeration through coordination N atoms. The NFs exhibited excellent selectivity to acetone a concentration 25 ppm at 300 °C because they had high...
In this paper, we consider a common unicast beamforming network where Alice utilizes the communication to Carol as cover and covertly transmits message Bob without being recognized by Willie. We investigate beamformer design of maximize covert rate when has either perfect or imperfect knowledge about Willie's channel state information (WCSI). For WCSI case, problem is formulated under constraint, develop applying semidefinite relaxation bisection method. Then, reduce computational...

The nanoprobes were synthesized the conjugate AFM bovine serum albumin (AFM-BSA), BSA, nanoparticles. Magnetic beads-based immunosorbent assay (MBISA) was used measure concentration direct competition between DLS determine unattached that positively proportional in sample. TEM images prove as-prepared able attach...
Abstract: Effects of pulsed electric field (PEF) treatments on the volatile profiles milk were studied and compared with pasteurized treatment high temperature short time (HTST) (75 °C, 15 s). Volatile compounds extracted by solid‐phase micro‐extraction (SPME) identified gas chromatography/mass spectrometry (GC‐MS) chromatography‐olfactometry (GC‐O). A total 37 determined GC‐MS, 19 considered to be major contributors characteristic flavor samples. PEF resulted in an increase aldehydes. Milk...
Electron spin resonance (ESR) spectroscopy was used to investigate the generation of free radicals under pulsed electric field (PEF) processing. Spin trapping studies, using 5,5-dimethyl-1-pyrroline N-oxide (DMPO), showed hydrogen in phosphate buffer and oleic acid emulsion. The concentration peroxide after PEF treatment determined by spectrofluorometric method. Electric strength has a significant effect on H2O2 (p < 0.05). In PEF-treated samples with 30 kV/cm 35 kV/cm, trace concentrations...
Contrary to the most existing works about full-duplex (FD) relaying with perfect channel state information (CSI), this paper studies outage performance of two-way FD decode-and-forward relay network under joint effects residual self-interference and imperfect CSI. We first derive exact closed-form expressions system probability, based on which we obtain probability cancellation investigate impacts CSI performance. In addition, gain more insights CSI, analyze optimal power allocation scheme...
The torsional wear behavior of monomer cast (MC) nylon composites reinforced with different glass fiber (GF) contents was studied. Different exhibited differently shaped torque–angular displacement curves. composite friction coefficient the main factor affecting torsion contact regime, and influenced by regime. Serious characterized a groove an approximately 1.5–4 mm radius that occurred in zone on steel surface. mass MC samples increased after test partial slipping pure reduced
Abstract Novel multiblock poly(arylene ether sulfone)s were prepared by a two‐pot method from phenoxide‐end‐capped fully disulfonated sulfone) oligomer and fluoride‐end‐capped nonsulfonated with block length of 10 as the hydrophilic hydrophobic moieties, respectively, subsequently used starting materials to be treated phosphorous pentoxide (P 2 O 5 ) get crosslinked membranes. The crosslinking reaction occurred between sulfonic acid groups activated ortho ‐hydrogen atoms linkage units in...
The zinc-finger protein ZBTB20 regulates development and metabolism in multiple systems, is essential for postnatal survival mice. However, its potential role the cardiovascular system remains undefined. Here, we demonstrate that critically involved regulation of cardiac contractility blood pressure At age 16 days, relatively healthy Zbtb20-null mice exhibited hypotension without obvious change heart rate or other evidence failure. Moreover, Zbtb20 deletion led to a marked reduction size,...
