Физика волновых процессов и радиотехнические системыBackground. To develop new terahertz wireless communication systems with high throughput and transmission speeds, such as 6G and above, effective control of the polarization direction of emitted terahertz waves is necessary, but most methods are ...

Small Size Wideband Monopole Antenna with Five Notch Bands for Different Wireless Applications [PDF]
Radioengineering, 2022 A broadband planar monopole antenna with five notch bands is proposed here. The antenna provides broadband from 1.94 GHz to 15.4 GHz with five notch bands covering 3.1-4.1 GHz, 6-6.4 GHz, 8.2-9.2 GHz, 10-11.6 GHz, and 12.38-12.89 GHz.

Acoustic radiation from the end of two-dimensional duct, effects of uniform flow and duct lining [PDF]
, 1973 A study is presented of the radiation of acoustic modes from the end of a duct immersed in a uniformly moving medium. It is shown that the uniform flow has roughly the same effect as an increase in frequency at constant mode number: the number of lobes ...

Thermal radiation as a probe of one-dimensional electron liquids
, 2018 Motivated by recent developments in the field of plasmonics, we develop the theory of radiation from one-dimensional electron liquids, showing that the spectrum of thermal radiation emitted from the system exhibits signatures of non-Fermi liquid behavior.

Molecular Oncology, EarlyView.Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

Anomaly and Hawking radiation from regular black holes
, 2008 We consider the Hawking radiation from two regular black holes, the minimal model and the noncommutative black hole. The flux of Hawking radiation is derived by applying the anomaly cancellation method proposed by Robinson and Wilczek.

Molecular Oncology, EarlyView.We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Far-field radiation of aft turbofan noise [PDF]
Approximate expressions were developed for the noise radiation from the aft duct. The results of approximate aft radiation equation compare favorably to more exact Wiener-Hopf radiation results.
