Hf Xl: Adaptive Wideband Hf Transmissions
This paper presents a solution to increase the throughput of an HF (High Frequency) physical (PHY) layer in particular to allow for services such as IP over HF. Additionally, this new PHY layer can improve the adaptability of the waveform to the channel variations, in particular to limit the retransmissions due to errors. Taking into consideration the existing HF spectrum occupancy and its high...
متن کاملPressure induced shifts in HCl/HF and HF/HCI systems
2014 As a sequel to a previous theoretical study of pressure induced lineshifts in the spectra of diatomic molecules pressurized by polar gases, some new experimental results became recently available and are reported in this paper. They concern the shifts in the HF(0-2) band due to HCl, and the HCl(0-1) and HCl(0-2) bands due to HF, for which predictions have been previously published. In the ...
متن کاملPractical HF Digital Voice
[Editor’s note: We goofed! The transmission of telephony in digital format (emission designator J1E or J2E) is perfectly legal in the phone bands. The restriction placed on transmitted baud rate by §97.307(f)(3) of the FCC rules does not apply. In fact, there is no upper limit on the bit rate for this mode. See the sidebar by ARRL Technical Relations Manager Paul Rinaldo, W4RI. Some of this mat...
متن کاملThe OxyS regulatory RNA represses rpoS translation and binds the Hfq (HF-I) protein.
The OxyS regulatory RNA integrates the adaptive response to hydrogen peroxide with other cellular stress responses and protects against DNA damage. Among the OxyS targets is the rpoS-encoded sigma(s) subunit of RNA polymerase. Sigma(s) is a central regulator of genes induced by osmotic stress, starvation and entry into stationary phase. We examined the mechanism whereby OxyS represses rpoS expr...
متن کاملCombative HF-rTMS treatment, for a bipolar I patient, following unsuccessful ECT.
We aimed to Examine the safety and effectiveness of HF-rTMS in a treatment-refractory bipolar I patient in a mixed affective episode. Our case illustrates that "combative" HF-rTMS therapy could be a safe and valid treatment alternative for refractory bipolar I patients in mixed episode, not successfully treated with ECT.
