OS, overall survival RFS, relapse free survival LRC, local regional control Radi., radiotherapy Radi.Chemo., concurrent chemoradiotherapy. (I) LRC analysis for patients with high-score by 22-gene signature. (H) LRC analysis for patients with low-score by 22-gene signature. (G) LRC analysis for all patients at clinical low-risk. (F) RFS analysis for patients with high-score by 22-gene signature. (E) RFS analysis for patients with low-score by 22-gene signature. (D) RFS analysis for all patients at clinical low-risk. (C) OS analysis for patients with high-score by 22-gene signature. (B) OS analysis for patients with low-score by 22-gene signature. (A) OS analysis for all patients at clinical low-risk. The P-value of each pair of Kaplan-Meier curves is calculated by log-rank test. Kaplan-Meier curves show the outcome of patients with different postoperative treatments. The upper, middle and the bottom panels show OS, RFS and LRC, respectively. The entire cohort of low-risk patients (the left column), low-score subgroup (the middle column) and high-score subgroup (the right column) stratified by 22-gene signature are analyzed respectively. It’s not limited to any particular frequency band and it also supports conventional and trunked operation.Predictive value of 22-gene signature in patients at clinical low-risk. NXDN: NXDN is a FDMA technology, similar to DMR, which operates in a 6.25 kHz channel spacing. DMR is increasingly used by businesses such as mining, utilities and transport throughout the world. Tier 2 DMR offers conventional operation and Tier 3 DMR offers trunked operation. It’s a TDMA technology which uses 2-time slots and operates in the 12.5 kHz channel spacing, available in any licensed frequency. It is also TDMA and offers two time slots in a single 12.5 kHz channel spacing given the equivalent of a 6.25 kHz channel.ĭMR: One of the newest open radio standards is called digital mobile radio or DMR for short. RFS, relapse free survival LRC, local regional control Radi., radiotherapy Radi. The essay was elaborated following the deductive. (B) OS analysis for patients with low-score by 22-gene signature. Phase 2 is a more recent development and is only available in trunked. An analysis was made of the Mexican radio industry and the main groups that comprise it, describing the financial information that is available. Phase 1 is an FDMA technology operating in the 12.5 kHz channel spacing. It can be employed by non-public safety users as well. P25 can be used in any licensed frequency that a public safety agency has whether it be VHF, UHF, 700, 800, even 900 MHz. P25 Phase 1 differs from Tetra by being an FDMA technology and also supporting conventional, trunked, and simulcast operation (or a combination of all three of these). P25: Another major open standard for digital radio technology is APCO Project 25 or P25 for short which was developed specifically for public safety agencies in the United States. Tetra operates in specific bands: 380 to 420 MHz and in the 700/800 MHz system. It’s very popular amongst large public safety agencies and used in the airports and has strong data applications. Tetra is a 4-slot TDMA technology that works in 25 kHz (wideband) channel spacing. It’s very similar to GSM used in modern digital cellphones. One of these is Tetra, developed in Europe in the late eighties. Tetra: As the world becomes more digital, a number of digital radio technologies have emerged. A number of different manufacturers support this trunking technology. It is named after the UK Ministry of Post and Telegraph that invented this particular open standard. MPT1327: Perhaps the most widely used analog trunking technology today is called MPT 1327. Almost every major manufacturer in the world supports some form of conventional FM technology. Next we’ll cover the different radio technologies that actually support these different types of operation.Ĭonventional FM: As previously mentioned, conventional FM is a popular technology in analog radio. We have now covered Conventional, Trunking, and Simulcast systems.
