Systemic lupus erythematosus (systemic erythematosus, SLE) may affect the development of chondromalacia patellae (CMP) through immune mechanism; in order to investigate causal effect between SLE and patellae, genome-wide association study (GWAS) was conducted a large European population. GWAS), mutually independent loci associated with respectively were extracted as instrumental variables (SNPs), three Mendelian randomisation (MR) analyses applied relationship, i.e., inverse variance...
Peer practice teaching is a kind of student-oriented method, which refers to the clinical skills, so that students can learn and independently, teach each other, correct think exchange discuss within team, no longer just directly inculcate content study students, but provide with problematic situations, some cases problems in course, actively think, independently explore, conducting practical activities on their own The application peer education reform skills promotes interns’ independent...
It has been promising to provide personalized services for improving our living environment in support of information technologies. Sitting is one the frequent actions daily life, especially people who work office. In this paper, we present design and implementation a sensing cushion. The cushion's about seated postures can be used help avoid adverse effects sitting long periods time or predict activities human-computer interface. seat pan backrest surface mounted with simple binary valued...
A new data acquisition system including a Field Programmable Gate Array (FPGA) based time-resolved scaler was developed for laser-induced fluorescence and beam bunch coincidence measurements. The FPGA tested in collinear laser-spectroscopy experiment on radioactive 37K at the BEam COoler LAser spectroscopy (BECOLA) facility National Superconducting Cyclotron Laboratory Michigan State University. 1.29 μs width from buncher repetition rate of 2.5 Hz led to background suppression factor 3.1 ×...
Imaging the spatial precession cone-shaped targets with narrowband radar is a new technical approach in mid-course recognition problem. However, most existing time-frequency methods still have some inevitable deficiencies for extracting micro-Doppler information practical applications, which leads to blurring of image. A imaging algorithm proposed. The instantaneous frequency each scattering point gained by using improved Hilbert-Huang transform, then positions points parameter domain are...
Purpose To present a computational procedure for accelerated, calibrationless magnetic resonance image (Cl‐MRI) reconstruction that is fast, memory efficient, and scales to high‐dimensional imaging. Theory Methods Cl‐MRI methods can enable high acceleration rates flexible sampling patterns, but their clinical application limited by complexity large footprint. The proposed procedure, HIgh‐dimensional fast convolutional framework (HICU), provides memory‐efficient recovery of unsampled k‐space...
A novel algorithm for the mobile station (MS) location estimation with none line of sight (NLOS) error in wireless network is proposed this paper. In algorithm, MS problem formulated as a simple linear approximation vector space data corrupted by NLOS errors. The M-estimator employed to eliminate errors, and recursive developed solve M-estimation normal equations. Compared conventional algorithms, does not rely on prior knowledge statistical model measurement noise. Another advantage that...

In phase-contrast magnetic resonance imaging (PC-MRI), spin velocity contributes to the phase measured at each voxel. Therefore, estimating from potentially wrapped measurements is task of solving a system noisy congruence equations. We propose Phase Recovery Multiple Wrapped Measurements (PRoM) as fast, approximate maximum likelihood estimator multi-coil data with possible amplitude attenuation due dephasing. The can recover fullest extent unambiguous velocities, which greatly exceed twice...

We consider the maximum likelihood (ML) parameter estimation problem for mixed integer linear models with arbitrary noise covariance. This appears in applications such as single frequency estimation, phase contrast imaging, and direction of arrival (DoA) estimation. Parameter estimates are found by solving a closest lattice point problem, which requires basis. In this letter, we present basis construction ML conclude simulated results from DoA imaging.
In phase-contrast magnetic resonance imaging (PC-MRI), the velocity of spins at a voxel is encoded in image phase. The strength encoding gradient offers trade-off between velocity-to-noise ratio (VNR) and extent phase aliasing. Phase differences provide invariance to an unknown background Existing literature proposes processing reduced set difference equations, simplifying unwrapping problem expense VNR or unaliased range velocities, both. Here, we demonstrate that fullest unambiguous...
A platform of spatial estimation, which is based on Matlab GUI, was established.
