The introduction of micropatterns is an effective strategy in enhancing the sensitivity of capacitive pressure sensors. Towards this goal, scientist in China developed a novel approach for fabricating random conical array (RCA) microstructures based on laser speckle grayscale lithography.
In a machine learning paper recently published in the journal npj Computational Materials, a team of researchers from Sandia National Laboratories and Brown University have introduced a universal way to accelerate virtually any kind of simulation.
A new study finds that the extent to which U.S. adults support newly appointed justices to the Supreme Court strongly influences the extent to which they support the high court as an institution.
Researchers in China have developed a dual-path snapshot compressive microscopy (DP-SCM) system that enables high-speed, high-resolution, and large field-of-view imaging for real-time monitoring of ultrafast laser material processing.
Miniaturized fiber-optic magnetic field sensors have attracted intensive interests due to the superiorities of anti-electromagnetic interference and compactness. Scientist in China developed an ultracompact multicore fiber (MCF) tip probes for magnetic field and temperature discriminative sensing. The size of the whole sensing probes does not exceed the inherent outer diameter of the MCF, which means a significant reduction in the size of multi-parameter sensor. The technique will open new avenues towards the realization of an all-fiber miniaturized multi-parameter sensor.
Mode division multiplexing technology is regarded as a promising solution to solve the capacity crunch of the standard single-mode fiber transmission system. However, the differential mode gain arising in the few-mode fiber transmission system would increase the complexity of the received signal processing.
Depth measurement and three-dimensional (3D) imaging under complex reflection and transmission conditions are challenging and even impossible for traditional structured light techniques, owing to the precondition of point-to-point triangulation. Qican Zhang and Zhoujie Wu from China’s Sichuan University and their colleagues now report a multi-scale parallel single-pixel imaging method that efficiently separates and utilizes different illumination and reflection components for dynamic depth measurement on multi-type surfaces and 3D imaging through complex transmission media, such as volumetric scattering media and semitransparent surface. The team demonstrated its effectiveness and results are promising for 3D imaging and sensing applications in advanced manufacturing, autonomous driving, and biomedical imaging.
A cutting-edge study has unveiled the sophisticated methods pathogens use to weaken plant defenses. It shows how a pathogen's effector protein targets the chloroplast protein StFC-II, increasing its levels in chloroplasts and reducing the plant's ability to generate reactive oxygen species (ROS). This manipulation significantly compromises the plant's immune response, offering new insights into potential strategies for enhancing plant resistance to infections.
When hospitals replace registered nurses (RNs) with licensed practical nurses and unlicensed assistive personnel, patients are more likely to die, experience readmissions, and have longer hospital stays, and Medicare must bear millions of dollars annually in avoidable costs. Moreover, there is no business case for this practice—hospitals actually experience a negative return on investment.
