Citizens Band (CB) The Citizens Band radio service is a private, two-way, short-distance voice communications service for personal or business activities of the general public. In the United States, AM and SSB are permitted modes. Use of FM has been authorized in the US and Canada since 20...
In the literature, there is no study investigating the coexistence of colonic polyps and thyroid nodules. Therefore, this study was designed to investigate thyroid nodule prevalence in patients with colonic polyps. Material and Methods. Sixty-six patients with colonic polyps and 146 patients without ...
The variability of the length and frequency of steps was measured in sighted and visually impaired walkers at three different paces. The variability was low, especially at the preferred pace, and similar for both groups. A model incorporating step counts and step frequency provides good estimates ...
We numerically and experimentally demonstrate efficient generation of an equalized optical comb with 150-nm bandwidth. The comb was generated by low-power, continuous-wave seeds, eliminating the need for pulsed laser sources. The new architecture relies on efficient creation of higher-order mixing tone...
setigenis a Python library for generating and injecting artificial narrow-band signals into radio frequency data, by way of data formats used extensively by theBreakthrough Listen (BL) team @ Berkeley. The main module ofsetigenis based on creating synthetic spectrogram (dynamic spectra) data, showi...

calculated their frequency band structures for this kind of photonic crystal and found existing a large absolute band gap in the low and high frequency regions by using the plane wave expansion method.The photonic band structure and density of state of a two-dimensional photonic crystals of square...
Frequency band selection for tuning an antenna are disclosed. In one example, one of a Received Signal Strength Indicator (RSSI) value and an echo value of a plurality of frequency bands is obtained. Based on one of the RSSI values or the echo values of the frequency bands, a frequency ...
In addition, the occurrence frequency of high-latitude aurora increases in 1837–1900. An upward trend in the occurrence frequency of aurora is also observed at the St. Petersburg observatory (Pavlovsk, Φ = 56°). This trend apparently is evidence of an increase in the open regions of solar...
