Coded aperture compressive temporal imaging (CACTI) enables the capture of complex dynamic scenes in a single exposure. In this Letter, we introduce a dual-optical-path (DoP) system with conjugate masks employing a single digital micromirror device (DMD) to simultaneously capture the original and complementary measurements to enhance the reconstruction quality. Our findings demonstrate that combining these measurements improves spatial resolution, while their differential values provide temporal information and cancel out noise.

This study introduces a data-driven, bottom-up approach to urban delineation, integrating feature engineering with the Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm, which represents a significant improvement in precision and methodology compared to traditional approaches that rely on simplistic OpenStreetMap (OSM) road node data aggregations. By employing a broad array of OSM categories and refining data selection through feature engineering, our research significantly enhances the precision and relevance of urban clustering. Using Bavaria, Germany, as a case study, we demonstrate that feature engineering effectively reduces noise and mitigates common DBSCAN clustering pitfalls by filtering out irrelevant and autocorrelated data.

Zearalenone (ZEN), a non-steroidal estrogenic mycotoxin, contaminates animal feed and grain crops, thereby entering the food chain and posing a significant threat to human health. Consequently, there is an urgent need for a sensitive and rapid method for detecting trace levels of ZEN. In this study, we developed a phage-displayed antigen-binding fragment (Fab-phage) and established a Fab-phage-based enzyme-linked immunosorbent assay (Fab-pELISA) for ZEN detection.

The von Hippel-Lindau (VHL) tumor suppressor gene VHL is a classic tumor suppressor that has been identified in family members with clear cell renal cell carcinomas, central nervous system and retinal hemangioblastomas, phaeochromocytomas, and pancreatic neuroendocrine tumors. The well-defined function of VHL is to mediate proteasomal degradation of hydroxylated hypoxia-inducible factor α proteins, resulting in the downregulation of hypoxia-responsive gene expression. Previously, we reported that VHL inhibits antiviral signaling by targeting mitochondrial antiviral signaling protein (MAVS) for proteasomal degradation.

This paper addresses the challenge of reconstructing the motion process of the safety and arming (S&A) mechanism in fuze by transforming the problem into a target detection and tracking problem. A novel tracking method, which fuses an improved Kalman filter with a temporal scale-adaptive KCF (AKF-CF), is proposed. The methodology introduces key innovations: (1) Extraction of grayscale images and directional gradient histogram (HOG) features of the target, followed by the use of an Adaptive Wave PCA-Autoencoder (AWPA) method to accurately capture multi-modal and multi-scale features of the target; (2) Application of bilinear interpolation and hybrid filtering techniques to generate a spatial and temporal scale-adaptive bounding box for the filtered target, enabling dynamic adjustment of the tracking box size; (3) Integration of an occlusion-aware mechanism using average peak correlation energy (APCE) to trigger Kalman-based position prediction when the target is occluded, thus mitigating tracking drift.

Accumulating evidence indicates that drug addiction may lead to adaptive behavioral changes in offspring, potentially due to epigenetic modifications in parental germline. However, the underlying mechanisms remain inadequately understood. In this study, we show that paternal heroin self-administration (SA) increased heroin-seeking behavior in the F1 generation, when compared with offspring sired by yoke-infused control males, indicating cross-generational impact of paternal voluntary heroin seeking behavior.

Biotoxins, known for their ubiquity and potent toxicity, pose significant threats to ecosystems and human health, highlighting the urgency the development of robust detection methods. Despite the significant potential of surface-enhanced Raman spectroscopy (SERS) in analytical science, challenges emerge when dealing with low Raman active molecules, such as biotoxins. Our study addresses this by introducing an innovative, ultrasensitive, clean-background coffee ring SERS (CC-SERS) platform, specifically designed for the detection of neo-saxitoxin (neo-STX), saxitoxin (STX), microcystin-LR (MC-LR), and microcystin-RR (MC-RR) using the AgNPs@AgO@AgCl coffee rings.

Background: Fospropofol, a water-soluble prodrug of propofol, is metabolized into propofol by alkaline phosphatase after administration. This study aimed to develop a pharmacokinetic-pharmacodynamic (PK-PD) model that correlates the propofol concentration in exhaled air (Ce-pro-f) with its anesthetic effects, as measured by the bispectral index (BIS) in beagles.

Methods: Beagles receiving a single intravenous infusion of fospropofol at varying doses were divided into three groups (n = 6): the DBL-fospro group (15 mg/kg), the DBM-fospro group (30 mg/kg), and the DBH-fospro group (60 mg/kg).

While propofol can be detected in exhaled breath in rats, robust evidence supporting its correlation with plasma concentrations or its use in predicting plasma levels remains lacking. In this study, eighteen mechanically ventilated rats were divided into three groups and injected with low (Group BL, = 6), medium (Group BM, = 6), or high (Group BH, = 6) doses of propofol. The propofol concentration in exhaled breath (Ce-pro) was determined online using vacuum ultraviolet time-of-flight mass spectrometry (VUV-TOF MS), while the propofol concentration in plasma (Cp-pro) were measured using high-performance liquid chromatograph.

Background: Opinions regarding the role and value of ultrasound in the diagnosis of prenatal hypospadias are diverse. Although hypospadias is not a fatal malformation, a higher degree of severity exerts a significant impact on children's physiology and psychology. On the other hand, hypospadias may be accompanied by accompanying anomalies, syndromic conditions, and fetal growth restriction (FGR).

As an important subclass of metal-organic frameworks (MOFs), anion-pillars MOFs (APMOFs) have recently exhibited exceptional performances in separation and purification processes. The adjustment of pore sizes and environments of APMOFs can be finely tuned through judicious combination of organic ligands, anion pillars, and metal ions. Compared to widely investigated anion pillars, organic ligands are more crucial as they allow for a broader range of pore sizes and environments at the nanometer scale.
