In recent years, attentions have been focused on 3D (three-dimensional) beamforming which can improve cell average and edge user throughput and eliminate the interference to adjacent cells. In the work towards calibration of 3D channel model, it seems that elevation beamforming with fixed electrical downtilt of 102 degrees has a good SINR (signal to interference and noise ratio) performance in ...

BACKGROUND In patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS), identification of left main and/or 3-vessel disease (LM/3VD) is crucial for deciding whether to initiate early treatment with clopidogrel, which can increase the risk of surgical bleeding. METHODS AND RESULTS On admission, the clinical factors of 501 patients with NSTE-ACS, who underwent coronary angiogr...

All atypical antipsychotics avoid extrapyramidal side-effects yet differ in their propensity to cause other side-effects, like prolactin elevation. We proposed that the atypical antipsychotics with a propensity for prolactin elevation would show a higher pituitary versus striatal D2 receptor occupancy. To investigate this hypothesis, we tested four atypical antipsychotics, two that are commonly...

BACKGROUND Most research investigating the neural basis of social emotions has examined emotions that give rise to negative evaluations of others (e.g. anger, disgust). Emotions triggered by the virtues and excellences of others have been largely ignored. Using fMRI, we investigated the neural basis of two "other-praising" emotions--Moral Elevation (a response to witnessing acts of moral beauty...

BACKGROUND The serum tumor markers CA 19-9 and CA 125 are the serologic markers used for the monitoring of biliopancreatic and ovarian cancer, respectively. They are reported to be elevated in a variety of nonneoplastic clinical situations, including end-stage liver disease (ESLD). However, their prevalence and degree of elevation in patients with ESLD remained unclear. AIM To examine the pre...

Variation in nutrient allocation can influence the timing of breeding and ultimately reproductive output. Time space constraints might exist, however, if fewer food resources are available to meet costs reproduction early during season. Here, for first time, we test whether nutrient-allocation strategies a shrub-dependent avian species differ with different ecoregions: high-elevation landscape,...

Mechanisms of elevation of active tone in arterial smooth muscle of spontaneously hypertensive rats and effects of antihypertensive treatments are reviewed. Spontaneously hypertensive rats are created by Okamoto et al. and classified mainly into three strains, SHR, SHRSP and M-SHRSP. Blood pressure of the rats is higher in this order. The aortic smooth muscle of these rats exhibits elevation of...

Ecological environmental security in karst areas is an issue of global concern. Identifying the ecological landscape pattern (ELSP) key to promoting protection and alleviating land development utilization impacts. sources (ESs) corridors (ECs) are important bases for constructing ELSP. We used five influencing factors (land use type, digital elevation model (DEM), rocky desertification degree, ...

The issue of screen size is discussed with respect to the task of navigating in 3D computer graphics environments. Two variables are isolated, the observer’s visual field of view (observer VA) subtended by a screen, and the viewing frustum angle (frustum VA) determined by the computer graphics geometry. It is possible to have these set to be identical, which according to one hypothesis should l...
