We introduce PointConvFormer, a novel building block for point cloud based deep network architectures. Inspired by generalization theory, PointConvFormer combines ideas from convolution, where filter weights are only on relative position, and Transformers which utilize feature-based attention. In attention computed feature difference between points in the neighborhood is used to modify convolutional at each point. Hence, we preserved invariances whereas helps select relevant convolution....
Two-dimensional (2D) transitional metal dichalcogenides (TMDs) have garnered significant attention due to their potential for next-generation electronics, which require device scaling. However, the performance of TMD-based field-effect transistors (FETs) is greatly limited by contact resistance. This study develops an effective strategy optimize resistance WSe2 FETs combining doping and 2D metallic electrode materials. The regions were doped using a laser, TaSe2 flakes stacked on as...
Exploration and construction of novel π-conjugated organic semiconductors with low cost, small background interference, excellent performance as surface-enhanced Raman scattering (SERS) substrates is one the current focuses for development SERS technology. Based on precise control over synthesis conditions, a series large-area tetraphenylporphyrin-based 2D covalent-organic framework membranes (2D-porphyrin-COFs) high uniformity precisely controllable thickness are constructed substrates. The...
Abstract The 2D material rhenium selenide (ReSe 2 ) has attracted significant interest due to its p‐type transport properties and anisotropic lattice structure. Its uniquely narrow bandgap of 0.9–1 eV enables efficient near‐infrared (NIR) detection. However, the growth large‐area ReSe mostly faces challenges such as high cost precursors reaction temperatures incompatible with back‐end‐of‐line (BEOL) processes. This work demonstrates an low‐cost method grow monolayer at significantly low...
Recently, there is significant interest in performing convolution over irregularly sampled point clouds. Point clouds are very different from raster images, that one cannot have a regular sampling grid on clouds, which makes robustness under irregular neighborhoods an important issue. Especially, the k-nearest neighbor (kNN) neighborhood presents challenges for generalization because location of neighbors can be between training and testing times. In order to improve samplings, this paper...

A liquid core optical fiber (LCOF) composed of hollow and a solution Eu(TTA)3Phen (TTA=2-thenoyltrifluoroacetone, Phen=1, 10-phenanthroline) in dimethyl sulfoxide (DMSO) has been fabricated, which the concentration DMSO is 0.8 wt.%, diameter LCOF 10 μm, length 8.1 cm. By end pumping with diode-pumped solid-state laser at 355 nm, small signal 613 nm was amplified gain 8.2 dB pump power 203 mW. Based on this experimental result, amplifier can be realized by LCOF, wide potential applications...
Collecting surrounding vehicles' motion information is one of the key issues for accident prevention and autonomous driving. Although multi-vehicle simulation frameworks are widely provided, We need a platform that enable inter-vehicle V2X communications. In this work, based on open source platform, CARLA, we extend implement several modules to build framework. proposed framework, vehicles allowed share their profiles sensory data through With other vehicles, car can thus make more...
Multiple-quantum-well (MQW) diodes have a variety of light emission, transmission, modulation, and detection functions. In particular, they feature an emission-detection spectral overlap region, allowing them to be used as both transmitters receivers at the same time. Here, we vertically assemble red, green, blue MQW create wavelength-division multiplexing (WDM) by using distributed bragg reflector (DBR) technique. A single-link communication system, in which longer-wavelength photons can...
Abstract Circularly polarized luminescence (CPL) materials hold significant value in various fields, including information storage, secure communication, three‐dimensional displays, biological detection, and optoelectronic devices. Using the Langmuir‐Schaeffer (LS) assembly technique, we successfully construct a series of large‐area flexible optical ultrathin films. Impressively, inorganic assembled films exhibit excellent CPL activity covering visible to near‐infrared (NIR) region, with...
Multiple-quantum well (MQW) diodes can be used as bifunctional due to the emission-detection spectral overlap. When integrated with magnetic fluids (MFs) that have tunable refractive index, they designed micro field sensors. The sapphire substrate of MQW diode chip consists an transmitter and receiver is directly exposed MF, external strength change index at boundary between thus modulating reflected light realizing sensing. Verified by experimental measurements, micromagnetic sensor has a...
