WBAN Channel Modeling for 900 MHz and 60 GHz Communications
IEEE Transactions on Antennas and Propagation, 2021 This article deals with the experimental characterization of the on-body propagation channel for applications in wireless body area networks (WBANs). The on-body propagation was studied between two quarter-wavelength monopole antennas in the 900 MHz band

Tectonics, Volume 41, Issue 12, December 2022., 2022 Abstract Detrital zircon from Late Cretaceous rocks of the Insular Superterrane have become an important constraint on Cordilleran paleogeography. These interpretations are largely based on the occurrence of a unique detrital zircon facies characterized by a broad Paleoproterozoic (mode 1.70 Ga) and narrow Mesoproterozoic mode (1.38 Ga) in Cordilleran ...

A COMPACT DUAL-BAND FLEXIBLE ANTENNA FOR APPLICATIONS AT 900 AND 2450 MHZ
, 2021 A dual band flexible antenna for applications at 900 and 2450 MHz is proposed in this paper. The antenna offers a compact size of 0.23λo × 0.120λo × 0.0007λo, where λo is the wavelength at the lower resonance.

Muroid rodent phylogenetics: 900-species tree reveals increasing diversification rates
PLoS ONE, 2017 We combined new sequence data for more than 300 muroid rodent species with our previously published sequences for up to five nuclear and one mitochondrial genes to generate the most widely and densely sampled hypothesis of evolutionary relationships ...

Journal of Spectroscopy, Volume 26, Issue 2, Page 141-149, 2011., 2011 In this paper dental ceramic samples from seven vendors were studied. The elemental composition for each type was investigated using the ICP‐OES and the XRF. Assessment of the seven types of ceramic was also successfully achieved using the XRD spectral data and processed with Principal Component Analysis (PCA).

National Toxicology Program technical report series, 2018 The predominant source of human exposure to radio frequency radiation (RFR) occurs through usage of cellular phone handsets. The Food and Drug Administration nominated cell phone RFR emission for toxicology and carcinogenicity testing in 1999.

Constraints on the FRB rate at 700-900 MHz [PDF]
, 2016 Estimating the all-sky rate of fast radio bursts (FRBs) has been dicult due to smallnumber statistics and the fact that they are seen by disparate surveys in dierent regions of the sky. In this paper we provide limits for the FRB rate at 800 MHz based on
