Synthesis of a Galile oand Wi-Max Three-Band Fractal-Eroded Patch Antenna [PDF]
, 2007 In this letter, the synthesis of a three-band patch antenna working in E5-L1 Galileo and Wi − Max frequency bands is described. The geometry of the antenna is defined by performing a Koch-like erosion in a classical rectangular patch structure according ...

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 ...

Ku Band microstrip patch antenna
2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015 In this study, a microstrip antenna operating at 11.56 GHz is designed and simulation results are presented. The antenna air thickness is 5 mm and the gap between the antenna and ground is 2.5 mm. Cell size is regarded as 0.75 mm. The antenna was simulated in the frequency range of 5-15 GHz. S11, the input reflection coefficient parameter has the value

NKCC1: A key regulator of glioblastoma progression
Molecular Oncology, EarlyView.Glioblastoma (GBM) progression is driven by disrupted chloride cotransporter homeostasis. NKCC1 is highly expressed in stem‐like, astrocytic, and progenitor cells, correlating with earlier recurrence, while overall survival remains unaffected. NKCC1 serves as a prognostic marker and potential therapeutic target, linking chloride transporter imbalance ...
