Single-camera light field particle image velocimetry (LF-PIV) shows potential for three-dimensional (3D) flow measurements in scenarios with limited optical access but faces challenges of low spatial resolution. To address this issue, we propose a dual-frame tracking (LF-PTV) method that enhances resolution volumetric velocimetry. This approach combines line-of-sight estimation customized deep neural network to reconstruct volumes while suppressing elongation artifacts. A gradient-fitting...

Abstract Among various treatments employed to solve the global problem of bacterial infection, photodynamic therapy (PDT) is recognized as a method with great potential inactivate wide range bacteria without development drug resistance. However, many commonly used photosensitizers (PSs) have disadvantages poor water‐solubility and toxicity, which limits their clinical application. Additionally, nitric oxide (NO) has unique advantages in antibacterial due its small molecular weight. Herein,...

Abstract The anabolism of tumor cells can not only support their proliferation, but also endow them with a steady influx exogenous nutrients. Therefore, consuming metabolic substrates or limiting access to energy supply be an effective strategy impede growth. Herein, novel treatment paradigm starving‐like therapy—triple energy‐depleting therapy—is illustrated by glucose oxidase (GOx)/dc‐IR825/sorafenib liposomes (termed GISLs), and such triple therapy exhibits more tumor‐killing effect than...
