To guarantee the success of massive multiple-input multiple-output (MIMO), one of the main challenges to solve is the efficient management of pilot contamination. Allocation of fully orthogonal pilot sequences across the network would provide a solution to the problem, but the associated overhead would make this approach infeasible in practical systems. Ongoing fifth-generation (5G) standardisa...

Europium isotopic abundance fractions are reported for the very metal-poor, neutron-capture-rich giant stars CS 22892-052, HD 115444, and BD +17◦3248. The abundance fractions, derived from analysis of several strong Eu II lines appearing in high-resolution spectra of these stars, are in excellent agreement with each other and with their values in the Solar System: fr(Eu)≃ fr(Eu) ≃ 0.5. Detailed...

Here we report systematic comparison of the spectral properties of large-scale jets, hotspots and extended lobes in quasars and FR II radio galaxies recently observed with Chandra and ASCA. We argue that if the strong X-ray emission of the jet knots in these objects results from comptonisation of the CMB photons, as usually considered, the powerful large-scale jets are most likely far from the ...

characterized by its gray aerial mycelium color, hygroscopic spore mass and spiral spore chains with warty or spiny spore surfaces. It is nonchromogenic. Strain No. 7238 shows characteristics most closely related to Streptomyces antimycoticus and S. hygroscopicus, although there are differences in physiological characteristics and carbohydrate utilization. In terms of morphological characterist...

The poor flexural and damping properties of building materials damages concrete structures affects their service life when are subjected to dynamic loads. Three different dosages (i.e., 0%, 0.3%, 0.6%) organic phosphonates (HEDP.4Na) pouring methods conventional method, 90°-induced 150°-induced method) were designed improve the performance fiber-reinforced alkali-activated slag composites (FR-A...

OBJECTIVES/HYPOTHESIS The goal of this study was to present a classification based on the degree of pneumatization of the sphenoid sinus in the coronal plane that can be used to instruct preoperative planning for endoscopic endonasal surgery (EES). STUDY DESIGN Observational anatomical study. METHODS The geometry of sphenoid sinus pneumatization was characterized (n = 204 hemisinus) on high...

Cognitive impairments are a core feature in schizophrenia patients (SCZ) and are also observed in first-degree relatives (FR) of SCZ. However, substantial variability in the impairments exists within and among SCZ, FR and healthy controls (HC). A cluster-analytic approach can group individuals based on profiles of traits and create more homogeneous groupings than predefined categories. Here, we...

It is fascinating to think that the ideas of two 19th century naval architects could offer useful insights for 21st century scientists contemplating the exploration of our planetary system or monitoring the long-term effects of a neurosurgical procedure on gait. The Froude number, defined as Fr = v2/gL, where v is velocity, g is gravitational acceleration and L is a characteristic linear dimens...

Prevalence of Toxoplasma gondii infection in 510 free-range (FR) chickens (380 from 33 small farms, and 130 from a slaughter house for FR chickens) from Espírito Santo state, southeastern Brazil, was investigated. Antibodies to T. gondii were sought using commercial indirect haemagglutination (IHAT, Imuno-HAI Toxo(®), Wama Diagnóstica, São Paulo, Brazil, cut-off 1:16) and the modified agglutina...
