Due to the virtues of low-cost and high positioning accuracy, Single-Frequency Precise Point Positioning (SF-PPP) is becoming a prospective technique. However, SF-PPP not as widely used dual-frequency triple-frequency PPP at present, owing effect ionospheric delay residuals after model rectification. In recent years, with evolution multi-constellation Global Navigation Satellite Systems (multi-...

Abstract This article focuses on the Boycott, Divestment, and Sanctions (BDS) movement's utilization of ‘fluidity,’ conceptualized as ability to adapt campaign tactics multiple arenas political opportunity structures simultaneously. Framing BDS both a social movement transnational advocacy network, it demonstrates fluidity in context three campaigns: at 65th FIFA (Federation Internationale de F...

Global Navigation Satellite System (GNSS)-based positioning is experiencing rapid changes. The existing GPS and the GLONASS systems are being modernized to better serve the current challenging applications under harsh signal conditions. These modernizations include increasing the number of transmission frequencies and changes to the signal components. In addition, the Chinese BeiDou Navigation ...

GABAergic dysfunction is present in the hippocampus in schizophrenia (SZ) and bipolar disorder (BD). The trisynaptic pathway was "deconstructed" into various layers of sectors CA3/2 and CA1 and gene expression profiling performed. Network association analysis was used to uncover genes that may be related to regulation of glutamate decarboxylase 67 (GAD(67)), a marker for this system that has be...

BACKGROUND By international standards, water supplies in Perth, Western Australia, contain high trihalomethane (THM) levels, particularly the brominated forms. Geographic variability in these levels provided an opportunity to examine cross-city spatial relationships between THM exposure and rates of birth defects (BDs). OBJECTIVES Our goal was to examine BD rates by exposure to THMs with a hi...

Hundreds of brown dwarfs (BDs) have been discovered in the last few years in stellar clusters and among field stars. BDs are almost as numerous as hydrogen burning stars and so a theory of star formation should also explain their origin. The “mystery” of the origin of BDs is that their mass is two orders of magnitude smaller than the average Jeans’ mass in star–forming clouds, and yet they are ...

BACKGROUND & OBJECTIVES To investigate whether the operations of Type 1 hysterectomy and bilateral salpingo-oophorectomy performed for benign reasons have any effect on sexual life and levels of depression. METHOD This is a multi-center, comparative, prospective study. Healthy, sexual active patients aged between 40 and 60 were included into the study. Data was collected with the technique of...
