Azimuth Angle Estimation for a Reduced Radiation Region Formed by a Metaspiral Antenna
IEEE Access, 2019 A two-arm metaspiral antenna is presented, where the feeding voltage sources are expressed using excitation amplitude r and deviation angle δ. This excitation is decomposed into the odd mode and even mode components. The odd mode component forms a

Cylindrical universes with heat and null radiation flow
The Astrophysical Journal, 1992 We have discussed cylindrically symmetric models with the Kasnerian time evolution incorporating heat flow and null radiation flow with the perfect fluid. In the case of heat flow the Kasner spacetime is the matter-free limit of the model. We establish a general result that a static perfect fluid distribution will on Kasnerization (introduce t 4/3 , t ...

Molecular Oncology, EarlyView.In head and neck squamous cell carcinoma (HNSCC) p53 and p63 exert opposite roles on the transcription regulation of the lncRNA NEAT1. Under basal conditions, p53 levels are low and p63 represses NEAT1 expression. Upon genotoxic stress, p53 is rapidly induced, displacing p63 from the NEAT1 promoter leading to NEAT1 transcriptional activation and ...

Aging and Cancer, EarlyView.Cancer treatment is associated with measurable acceleration of biological aging across epigenetic, telomere, senescence, and immune biomarkers. However, biomarker validation and interventional strategies remain limited, especially in hematologic malignancies, underscoring the need for standardized multi‐omic aging assessments and adequately powered ...

Arthritis Care &Research, EarlyView.Objective Youth who experience a sport‐related knee injury have elevated odds of becoming overweight or developing obesity in 3 to 10 years, compounding their risk for posttraumatic osteoarthritis (PTOA). To inform prevention strategies, this study compared patterns of adiposity change between youth with a sport‐related knee injury and uninjured youth ...

Survival Outcomes in Older Adults with Axial Spondyloarthritis and Concomitant Cancer
Arthritis Care &Research, Accepted Article.Objective The objective of this study was to determine survival outcomes in older adults with axial spondyloarthritis (axSpA) and concomitant cancer. Methods We conducted a population‐based study using Medicare claims data linked to Surveillance, Epidemiology, and End Results data to determine overall survival (OS) and cancer‐specific survival (CSS) in
