To evaluate the anatomical features of C-shaped canal systems in Chinese mandibular second molars by cone-beam computed tomography (CBCT).A total 608 patients descent with healthy, well-developed were enrolled. These referred to West China Hospital Stomatology and required radiographic examination CBCT as part their routine dental treatment. Of examined images, 528 showed unilateral intact 80 bilateral molars. Bilateral molar data only used analyse distribution occurrences canals. The...
Substituted alkenes are pivotal structural motifs found in pharmaceuticals and agrochemicals. Although numerous methods have been developed to construct substituted alkenes, a generally efficient, mild, catalytic platform for the conversion of alkynes this highly functionalized scaffold via successive C-C bond forming steps remains high demand. Here we describe an intermolecular, regio- syn-stereoselective alkylarylation terminal with tertiary alkyl oxalates photoredox-Ni dual catalysis....
Abstract A stereodivergent reductive coupling reaction between allylic carbonates and vinyl triflates to furnish both E ‐ Z ‐configured 1,4‐dienes has been achieved by visible‐light‐induced photoredox/nickel dual catalysis. The mild conditions allow good compatibility of carbonates. Notably, the stereoselectivity this synergistic cross‐electrophile can be tuned an appropriate photocatalyst with a suitable triplet‐state energy, providing practical means alkene synthesis. Preliminary...
The effect of a negative Poisson ratio is experimentally revealed in the tension deformation natural layered ceramic. This can increase volume strain energy per unit by 1100% and, simultaneously, decrease about 44%, so that it effectively enhances capacity 1 order magnitude material. present study also shows physical mechanisms producing are attributed to climbing on one another nanostructures material, which provides guide design synthetic toughening composites.
The present study comprehensively analyzes error characteristics and performance of the two latest GPM-era satellite precipitation products over eastern China from April 2014 to March 2016. Analysis results indicate that have totally different spatial distributions total bias. Many underestimations for GSMap-gauged could be traced significant hit bias, with a secondary contribution missed precipitation. For IMERG, bias illustrates overestimation most part China, except upper reaches Yangtze...
Different from previous two-dimensional thermal weight function (TWF) method, a three-dimensional (3D) TWF method is proposed for solving elliptical interface crack problems in bimaterial structures under transient loading. The present 3D based on the Betti's reciprocal theorem powerful tool dealing with loading due to stress intensity factors (SIFs) of whole process obtained through static finite element computation. Several representative examples demonstrate that can be used predict SIFs...
Gaining insight into osmotic pressure and its biological implications is pivotal for revealing mechanisms underlying numerous fundamental processes across scales will contribute to the biomedical pharmaceutical fields. This review aims provide an overview of current understanding, focusing on two central issues: (i) how determine theoretically (ii) affects important activities. More specifically, we discuss representative theoretical equations models different solutions, emphasizing their...
Abstract Developing physical methods to modulate biomolecular clusters and condensates on cell membranes is of great importance for understanding physiological pathological processes as well stimulating novel therapeutic strategies. Here, we propose an effective means control receptor condensation the membrane via specific adhesion a supported lipid bilayer (SLB) with nanoscale topography. The mediated by receptors in that bind their ligands anchored SLB. Using Monte Carlo simulations...
We propose here a new method to make ceramics insensitive thermal shock up their melting temperature. In this the surface of was biomimetically roughened into nanofinned that creates thin air layer enveloping during quenching. This increases heat transfer resistance by about 10 000 times so strong gradient and stresses produced steep temperature difference in did not occur both on actual interior ceramics. effectively extends applications existing extreme environments.
Abstract Changes in the level of Yangtze River caused by anthropogenic water regulation have major effects on hydrological processes and cycle surrounding lakes rivers. In this study, we obtained isotopic evidence changes during two drought years 2006 2013. Isotopic demonstrated that δ 18 O δD levels exhibited high spatial heterogeneity from upper to lower reaches, which were controlled atmospheric precipitation, tributary/lake mixing, damming regulation, temperature. Both slope intercept...
SUMMARY Detailed investigations on the structural and mechanical properties of forewing cicada were carried out. Measurement structures wings showed that thickness membrane each cell diameter vein non-uniform in both longitudinal transverse directions, their means approximately 12.2 133.3 μm,respectively. However, aspect ratios bodies quite uniform equal to 2.98 2.13, respectively. Based measured thickness, mass area membranes cells,the mean density wing 2.3 g cm-3 2.8×10-3...
AimsAngiogenesis is critical for re-establishing blood supply to ischaemic myocardium after myocardial infarction (MI). Human studies have associated arterial baroreflex (ABR) deficiency with higher rate of sudden death MI. The present work was designed examine whether ABR affects angiogenesis in MI rats.
Neonatal hypoxia-ischemia is a major cause of brain damage in infants and may frequently present visual impairments. Although advancements perinatal care have increased survival, the pathogenesis hypoxic-ischemic injury long-term consequences to system remain unclear. We hypothesized that neonatal can lead chronic, MRI-detectable structural physiological alterations both eye brain's pathways.Eight Sprague-Dawley rats underwent ligation left common carotid artery followed by hypoxia for 2...
