Under contract to the European Space Agency (ESA), an expert team lead by Kayser-Threde GmbH has elaborated a design concept for the Precise Time Facility (PTF) for Europe’s satellite positioning system Galileo. The major purpose of the PTF is to generate, maintain, and distribute Galileo System Time (GST). The PTF is represented by an ensemble of atomic clocks (active H-maser, cesium) with app...

A photothermal film (PTF) with densely assembled gold nanoparticle-fixed beads on a polymer substrate is fabricated. Remarkably, a temperature rise higher than 40 °C is achieved in the PTF with only 100 seconds of artificial solar irradiation, and the output power of the thermoelectric device was enhanced to be one order higher than that without PTF. These results will pioneer a rapid solar the...

Conductive inks and adhesives were used in the earliest electronics. Thomas Edison was the first to propose conductive adhesives as a way to replace wires all the way back in 1904. Today, adhesives are used with conventional etched copper circuit boards and also with other Polymer Thick Film (PTF) materials to produce electronic products that can be built very efficiently. Safe, reliable and lo...

The treatment of domestic sewage at low temperature was studied in a two-anaerobic-step system followed by an aerobic step, consisting of an anaerobic filter (AF) + an anaerobic hybrid (AH) + polyurethane-foam trickling filter (PTF). The AF+AH system was operated at a hydraulic retention time (HRT) of 3+6 h at a controlled temperature of 13 degrees C, while the PTF was operated without wastewat...

A novel fixed point algorithm for positive tensor factorization (PTF) is introduced. The update rules efficiently minimize the reconstruction error of a positive tensor over positive factors. Tensors of arbitrary order can be factorized, which extends earlier results in the literature. Experiments show that the factors of PTF are easier to interpret than those produced by methods based on the s...

Defects in insulin-stimulated glucose uptake in skeletal muscle result from the dysfunction of insulin signaling including the phosphatidylinositol-3 kinase (PI3K) pathway and a novel β-arrestin-2-mediated signaling, which leads to insulin resistance (IR). Pollen Typhae, a Chinese herb, has been used for thousands of years in traditional Chinese m...
