The integrated frequency comb generator based on Kerr parametric oscillation has led to chip-scale, gigahertz-spaced combs with new applications spanning hyperscale telecommunications, low-noise microwave synthesis, light detection and ranging, and astrophysical spectrometer calibration. Recent progress in lithium niobate (LiNbO) photonic integrated circuits (PICs) has resulted in chip-scale, electro-optic (EO) frequency combs, offering precise comb-line positioning and simple operation without relying on the formation of dissipative Kerr solitons. However, current integrated EO combs face limited spectral coverage due to the large microwave power required to drive the non-resonant capacitive electrodes and the strong intrinsic birefringence of LiNbO.

Methods: In this retrospective study, LEN-treated patients with HCC were enrolled. Sarcopenia and myosteatosis were evaluated on the basis of baseline skeletal muscle index and mean muscle attenuation, respectively, on computed tomography at the L3 level.
: Diabetes mellitus (DM) is associated with worse surgical outcomes, and is a risk factor for bladder cancer and subsequent oncological outcomes. This study evaluated outcomes robot-assisted radical cystectomy (RARC) compared to open radical cystectomy (ORC) in patients with DM. : Data of adults ≥ 18 years old with DM who underwent radical cystectomy were extracted from the United States National Inpatient Sample database 2005-2018.

We explored the Steatosis-Associated Fibrosis Estimator (SAFE) score to predict HCC in MASLD and other CLD etiologies.
Methods: Patients with various CLDs were included from medical centers in Taiwan.
