Spatial Organization of Macrophages in CTL Rich Hepatocellular Carcinoma Influences CTL Antitumor Activity.

Despite the pivotal role of cytotoxic T lymphocytes (CTLs) in anti-tumor immunity, a substantial proportion of CTL-rich hepatocellular carcinoma (HCC) patients experience early relapse or immunotherapy resistance. However, spatial immune variations impacting the heterogeneous clinical outcomes of CTL-rich HCCs remain poorly understood. Here, we compared the single-cell and spatial landscapes of 20 CTL-rich HCCs with distinct prognoses using multiplexed in situ staining and validated the prognostic value of myeloid spatial patterns in a cohort of 386 patients.

A modified adaptive Kalman filter algorithm for the distributed underwater multi-target passive tracking system.

A modified adaptive Kalman filter (AKF) algorithm is proposed to make underwater multi-target tracking with uncertain measurement noise reliable. By utilizing the proposed AKF algorithm with three core points, including an adaptive fading factor, measurement noise covariance adjustment, and an adaptive weighting factor, the unknown measurement noise and state vector can be estimated with good accuracy and robustness. The practical trial data verify this algorithm, and it has proven superior to all traditional algorithms in this Letter based on the results that it reduces the estimated position RMSEs by at least 10.

An efficiency improvement method for high-voltage nanosecond pulse spiral generator based on optimized voltage wave propagation process.

The spiral generator, based on the principle of the electric field vector inversion, is capable of delivering repetitive high-voltage nanosecond pulses in the commercial portable pulsed x-ray source and gas switch trigger source. However, the spiral generator suffers from extremely low output efficiency, which significantly affects the compactness and accelerates the insulation film breakdown at electrode foil edges since the high charging voltage is required. A novel output efficiency improvement method for the spiral generator was proposed, implementing the permalloy film inside the passive layer to optimize internal voltage wave propagation processes during the pulser erection.

Automated high-resolution 3D inspection methods for sealant applications in aerospace based on line structured light.

Gluing is a critical step in aircraft sealing assembly, with glue profile inspection serving as the final quality assurance measure to ensure consistency and accuracy of the sealant coating, allowing timely detection and correction of defects to maintain assembly integrity and safety. Currently, existing glue inspection systems are limited to basic inspection capabilities, lack result digitization, and exhibit low efficiency. This paper proposes a 3D inspection technology for sealant coating quality based on line-structured light, enabling automated and high-precision inspection of sealant thickness, sealant width, positional accuracy, and overlap joint sealant contour through geometric computation.

Development of a 300 kV/3 kHz nanosecond pulse generator using semiconductor opening switches.

Revealing NOD1-Activating Gram-Positive Gut Microbiota via in Vivo Labeling with a meso-Diaminopimelic Acid Probe.

As an important receptor in a host's immune and metabolic systems, NOD1 is usually activated by Gram-negative bacteria having -diaminopimelic acid (-DAP) in their peptidoglycan (PGN). But some atypical Gram-positive bacteria also contain -DAP in their PGN, giving them the potential to activate NOD1. The prevalence of -DAP-type Gram-positive bacteria in the gut, however, remains largely unknown.
