Abstract Background The demographical and geographical distributions of health resources are important aspects healthcare access. Few studies have been published on resource allocation in TCM hospitals China despite public equity concerns. Methods This article uses the Gini coefficient agglomeration degree to analyze according demographic geographic configuration conditions order study from 2009 2018. Results From 2018, all regions per ten thousand people square kilometers showed overall...
It is the pursuit of a multiple-input-multiple-output (MIMO) system to approach and even break limit channel capacity. However, it always big challenge efficiently characterize MIMO systems in complex space get better propagation performance than conventional considering only free space, which important for guiding power phase allocation antenna units. In this manuscript, an Electromagnetic-Information-Theory (EMIT) based model developed efficient characterization space. The...
Abstract The thin film of heat-sensitive materials has been widely concerned with the current trend miniaturization and integration sensors. In this work, Mn 1.56 Co 0.96 Ni 0.48 O 4 (MCNO) films were prepared on SiO 2 /Si substrates by sputtering Mn–Co–Ni alloy target then annealing in air at different temperatures (650–900 °C). X-ray diffraction (XRD) field emission scanning electron microscopy (FE-SEM) analysis indicated that main crystalline phase MCNO was spinel crystal structure;...
There are many factors which can affect the muzzle velocity of projectile in system multi-stage synchronous inductive coilgun (SICG), and discharge position armature is important one. If with respect to a drive-coil changed when charge capacitor bank switched into circuit, launched by will change. In this paper, positions three-stage SICG investigated. The results indicate that best exists each stage. stage circuit passes through stage, be accelerated maximal velocity. obtained.

The analytic solutions of field pattern each mode are derived in frequency domain. deep learning technique is employed to effectively predict coefficients these over wide range (1.885–300 MHz) only given <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math...
Soft, conductive, and stretchable sensors are highly desirable in many applications, including artificial skin, biomonitoring patches, so on. Recently, a combination of good electrical mechanical properties was regarded as the most important evaluation criterion for judging whether hydrogel suitable practical applications. Herein, we demonstrate novel carboxylated carbon nanotube (MWCNT-COOH)-embedded P(AM/LMA)/SiO
Abstract Bile acids play important roles in lipid metabolism and glucose homeostasis. Limited research exist on the association between serum total bile acid (TBA) levels major adverse cardiovascular events (MACEs) patients with acute coronary syndrome (ACS), particularly those comorbid type 2 diabetes mellitus (T2DM). This study was conducted to examine relationship baseline TBA level T2DM status ACS after percutaneous intervention (PCI) identify predictive value of for a 2-year risk MACEs....
Pushing the information states' acquisition efficiency has been a long-held goal to reach measurement precision limit inside scattering spaces. Recent studies have indicated that maximal states can be attained through engineered modes; however, partial intrusion is generally required. While non-invasive designs substantially explored across diverse physical scenarios, of dynamic spaces remains challenging due intractable non-unique mapping problem, particularly in context multi-target...
