Macro-Driven VAR Forecasts: From Very High to Very Low-Frequency Data

Low Rate High Frequency Data Transmission from Very Remote Sensors

Benefits of Very High Frequency Total Lightning Mapping over Very Low or Low Frequency Cloud Lightning Detection for Meteorological Applications

As a thunderstorm approaches a fixed asset (90% of the time) where people are located, VHF cloud lightning mapping provides 10s of minutes of lead time before the first cloud-to-ground strokes reach this asset. At times when a thunderstorm develops directly over the fixed asset (~10% of the time), the cloud flash detection efficiency exceeding 90% maximizes lead time during thunderstorm growth ...

A Very Low Spurious X-Band Frequency Quadrupler with Very High Integration Using 3D-MMIC Technology

A highly integrated frequency quadrupler MMIC that uses three-dimensional MMIC (3D-MMIC) technology is presented. It consists of four driver amplifiers, two doublers, and a 2-band elimination filter. These seven circuits are integrated in only a 2.36 mm2 area. The filter sufficiently suppresses spurious output components. The third and fifth harmonic components, which are the spurious component...

Very low HbA1C, is it a problem?

Dear Editor An important problem to manage diabetes mellitus is controlling the patients` blood glucose. Fluctuation of blood glucose results in molecular biochemistry change and can result in unwanted diabetic complications (1). In clinical practice, hemoglobin A1C (HbA1C) is a common useful laboratory test to follow-up patients with diabetes (2). Sometimes, an unexpecte...
