Performance Comparison of Surface Sensitizers for Diode Laser Powder Bed Fusion of Polyamide 12
Laser‐generated nanoparticles transform standard PA12 powders into high‐performance, dye‐free feedstocks for diode laser 3D printing. Despite identical absorbance at 808 nm, CuS, LaB6, and CB coatings reveal striking differences in fusion and strength—unlocking new design space for recyclable, industrial‐grade polymers.

Gender Recognition Based on Sift Features
This paper proposes a robust approach for face detection and gender classification in color images. Previous researches about gender recognition suppose an expensive computational and time-consuming pre-processing step in order to alignment in which face

Mesoporous Silica Microspheres by Super‐Fast Alkaline Etching of Micrometer‐Sized Stöber Particles
Microscale silica particles are prepared along with a modified, scalable Stöber synthesis using the continuous addition of tetraethoxy silane to an ethanolic solution of ammonia with KCl. Etching with hydroxide ions at 95 °C gave porous analogs within minutes. Monodisperse particles are isolable in high yield after precipitation in ethanol.

Automatic mosaic method of remote sensing images based on machine vision
Unmanned Aerial Vehicle (UAV) remote sensing is a commonly used technical means in modern science and technology, but currently, remote sensing images captured by UAVs need to be spliced to obtain more comprehensive information.

Domain-Size Pooling in Local Descriptors: DSP-SIFT [PDF]
We introduce a simple modification of local image descriptors, such as SIFT, based on pooling gradient orientations across different domain sizes, in addition to spatial locations. The resulting descriptor, which we call DSP-SIFT, outperforms other methods in wide-baseline matching benchmarks, including those based on convolutional neural networks ...

The ultraselective H2S detection of the ZIF‐L/SnS2 heterostructure is demonstrated. The introduction of 2‐dimensional (2D) breathable ZIF‐L results in a substantial increase in H2S selectivity attributable to the molecular sieving effect, which impedes the permeation of gases with large kinetic diameters and high polarity.
