Wave-vector and polarization dependent impedance model for a hexagonal periodic metasurface exemplified through finite-difference time-domain simulations.

Optics express

Ding YS, He Y.
PMID: 29041754
Opt Express. 2017 Aug 21;25(17):20757-20769. doi: 10.1364/OE.25.020757.

An isotropic impedance sheet model is proposed for a loop-type hexagonal periodic metasurface. Both frequency and wave-vector dispersion are considered near the resonance frequency. Therefore both the angle and polarization dependences of the metasurface impedance can be properly and...

Perceptions of the activity, the social climate, and the self during group exercise classes regulate intrinsic satisfaction.

Frontiers in psychology

Maher JP, Gottschall JS, Conroy DE.
PMID: 26347696
Front Psychol. 2015 Aug 19;6:1236. doi: 10.3389/fpsyg.2015.01236. eCollection 2015.

Engaging in regular physical activity is a challenging task for many adults. Intrinsic satisfaction with exercise classes is thought to promote adherence to physical activity. This study examined the characteristics of exercise classes that impact within-person changes in intrinsic...

A simple and effective prognostic staging system based on clinicopathologic features of intrahepatic cholangiocarcinoma.

American journal of cancer research

Zhou H, Jiang X, Li Q, Hu J, Zhong Z, Wang H, Wang H, Yang B, Hu H.
PMID: 26175951
Am J Cancer Res. 2015 Apr 15;5(5):1831-43. eCollection 2015.

UNLABELLED: Incidence and mortality of intrahepatic cholangiocarcinoma (ICC) are increasing. However, its prognostic predictive system associated with outcome after surgery remains poorly defined. In this study, we conducted retrospective survival analyses in a primary cohort of 370 patients who...

Effects of different inhaled oxygen concentration and end-expiratory positive pressure on Pa-etCO2 in patients undergoing gynecological laparoscopic surgery.

International journal of clinical and experimental medicine

Geng G, Hu J, Huang S.
PMID: 24260603
Int J Clin Exp Med. 2013 Oct 25;6(10):956-9. eCollection 2013.

UNLABELLED: There is some disagreement about whether the PetCO2 is reliable in predicting the PaCO2 in laparoscopic procedures with CO2 inflation. The aim of the present study is to measure the Pa-etCO2 differences over time in healthy patients undergoing...

Signaling pathway of cardioprotection induced by monophosphoryl lipid A in rabbit myocardium.

Pathophysiology : the official journal of the International Society for Pathophysiology

Xiuhua L, Xudong W, Yue H, Chaoshu T, Jingyi S.
PMID: 12039651
Pathophysiology. 2002 Jun;8(3):193-196. doi: 10.1016/s0928-4680(02)00005-6.

OBJECTIVE: To investigate the effect of monophosphoryl lipid A (MLA) on ischemia/reperfusion (I/R) injury in rabbit heart and its signal transduction pathway. METHODS: Eighteen rabbits were randomly assigned to three groups: (1) MLA-group: Six rabbits received injection of MLA...

Synchronization study in ring-like and grid-like neuronal networks.

Cognitive neurodynamics

Qu J, Wang R, Du Y, Cao J.
PMID: 23372617
Cogn Neurodyn. 2012 Feb;6(1):21-31. doi: 10.1007/s11571-011-9174-9. Epub 2011 Sep 13.

In this paper, we study the synchronization status of both two gap-junction coupled neurons and neuronal network with two different network connectivity patterns. One of the network connectivity patterns is a ring-like neuronal network, which only considers nearest-neighbor neurons....

The Effect of Dantonic Pill on β -Catenin Expression in a Rat Model of Streptozotocin-Induced Early Stage of Diabetic Nephropathy.

Journal of diabetes research

Shuhong Z, Hongjun L, Bo C, Li X, Bingyin S.
PMID: 23691520
J Diabetes Res. 2013;2013:848679. doi: 10.1155/2013/848679. Epub 2013 Apr 14.

Diabetic nephropathy (DN) is one of the most common causes of end-stage renal failure. This study was performed to determine the effect of Dantonic Pill (DP) treatment on β -catenin expression in a rat model of streptozotocin- (STZ-) induced...

Modulating the Electronic Properties of Graphene by Self-Organized Sulfur Identical Nanoclusters and Atomic Superlattices Confined at an Interface.

ACS nano

Ma D, Fu Z, Sui X, Bai K, Qiao J, Yan C, Zhang Y, Hu J, Xiao Q, Mao X, Duan W, He L.
PMID: 30252446
ACS Nano. 2018 Nov 27;12(11):10984-10991. doi: 10.1021/acsnano.8b04874. Epub 2018 Sep 27.

Ordered atomic-scale superlattices on a surface hold great interest both for basic science and for potential applications in advanced technology. However, controlled fabrication of superlattices down to the atomic scale has proven exceptionally challenging. Here we develop a segregation...

Time-Resolved Tomographic Quantification of the Microstructural Evolution of Ice Cream.

Materials (Basel, Switzerland)

Mo J, Guo E, McCartney DG, Eastwood DS, Bent J, Van Dalen G, Schuetz P, Rockett P, Lee PD.
PMID: 30347641
Materials (Basel). 2018 Oct 19;11(10). doi: 10.3390/ma11102031.

Ice cream is a complex multi-phase colloidal soft-solid and its three-dimensional microstructure plays a critical role in determining the oral sensory experience or mouthfeel. Using in-line phase contrast synchrotron X-ray tomography, we capture the rapid evolution of the ice...

High levels of centrosomal protein 55 expression is associated with poor clinical prognosis in patients with cervical cancer.

Oncology letters

Qi J, Liu G, Wang F.
PMID: 29805659
