A field-deployable lateral flow assay for rapid and sensitive detection of nanoplastics
Plastic pollution has emerged as a global concern, with nanoplastics posing a distinct threat due to their small size, high mobility, and persistence. However, conventional nanoplastic detection techniques often rely on sophisticated instruments and extensive preprocessing, limiting their on-site ap...

High Spectral Energy Density All-Fiber Nanosecond Pulsed 1.7 μm Light Source for Photoacoustic Microscopy
We present a high spectral energy density all-fiber nanosecond pulsed 1.7 μm light source specifically designed for photoacoustic microscopy (PAM). The system targets the 1st overtone absorption of C–H bonds near 1720 nm within the near-infrared-III (NIR-III) window, where lipids exhibit strong opti...

New insights into the olfactory development disrupted by 4-tert-Octylphenol in offspring mice
4-tert-Octylphenol (4t-OP) is an endocrine-disrupting chemical widely used in industrial products that exert neurotoxic effects, thus affecting hippocampal neurogenesis and cognitive function. However, its effect on the subventricular zone (SVZ), a crucial neurogenic niche, remains unclear. The pres...

Longitudinal antibody titers measured after COVID-19 mRNA vaccination can identify individuals at risk for subsequent infection
Although COVID-19 posed a major threat, the success of mRNA vaccines enabled rapid development and distribution, helping to control the pandemic. However, vaccine-induced immunity wanes over time, and large individual differences make it difficult to design optimal booster strategies. Identifying po...

Discrete-Time Survival Analysis Incorporating Time Structure in Developmental Research
Discrete-time survival analysis (DTSA) is a method widely used by social and behavioral researchers as it aids in the exploration of patterns in time-to-event measures. However, the traditional DTSA models often fail to adequately represent the structured dynamics of hazardous processes. This stu...
