Multiphoton microscopy (MPM) is an enabling technology for visualizing deep-brain structures at high spatial resolution in vivo. Within the low tissue absorption window, shifting to longer excitation wavelengths reduces scattering and boosts penetration depth. Recently, 2200 nm window has emerged as last longest suitable MPM. However, multiphoton fluorescence imaging this not been demonstrated, due lack of characterization properties fluorescent labels. Here we demonstrate technologies...
Pansharpening aims to combine a high-resolution panchromatic (PAN) image with low-resolution multispectral (LRMS) produce (HRMS) image. Although pansharpening in the frequency domain offers clear advantages, most existing methods either continue operate solely spatial or fail fully exploit benefits of domain. To address this issue, we innovatively propose Multi-Frequency Fusion Attention (MFFA), which leverages wavelet transforms cleanly separate frequencies and enable lossless...
Semi-mangroves form a group of transitional species between glycophytes and halophytes, hold unique potential for learning molecular mechanisms underlying plant salt tolerance. Millettia pinnata is semi-mangrove that can survive wide range saline conditions in the absence specialized morphological physiological traits. By employing Illumina sequencing platform, we generated ∼192 million short reads from four cDNA libraries M. processed them into 108 598 unisequences with high depth coverage....
Lead-free double perovskites (DPs) have received a lot of attention owing to their good stability and environmental friendliness. They been widely used in the field optoelectronics because high quantum efficiency long carrier migration distance. However, application lead-free DPs ultrafast photonics is rarely explored. Cs2AgBiBr6, typical perovskite, has advantages such as toxicity free Pb, stability, strong nonlinear absorption, showing great potential photonics. date, there no reported...
Investigation of high-performance lasers monolithically grown on silicon (Si) could promote the development photonics in regimes other than 1.3 -1.5 µm band. 980 nm laser, a widely used pumping source for erbium-doped fiber amplifier (EDFA) optical communication system, can be as demonstration shorter wavelength lasers. Here, we report continuous wave (CW) lasing electrically pumped quantum well (QW) directly Si by metalorganic chemical vapor deposition (MOCVD). Utilizing strain compensated...
Abstract Multiphoton microscopy (MPM) enables deep brain imaging. Three optical windows: NIR‐I, NIR‐II, and NIR‐III are widely used. Recently, NIR‐IV (the 2200 nm window) has been demonstrated to be the last longest window for tissue MPM. However, so far MPM covers only two windows labeled by single fluorescent probe, one emission excitation. Here we demonstrate in vivo covering three windows, with at excitation NIR‐IV, ICG. The innovations include: (1) characterizing both 3‐photon...

To address the problems of reduced evaporation rate and increased ignition time kerosene droplets at sub-atmospheric pressures high temperatures, boron ethanol/water were selected as additives to be blended with RP-3 kerosene, respectively. The effects different types fuels on evaporation, micro-explosion, spontaneous characteristics tested compared using an independently designed, high-temperature, controlled-pressure experimental droplet system. A low-pressure environment (0.4 bar)...
Triton, a high-level Python-like language designed for building efficient GPU kernels, is widely adopted in deep learning frameworks due to its portability, flexibility, and accessibility. However, programming parallel optimization still require considerable trial error from Triton developers. Despite advances large models (LLMs) conventional code generation, these struggle generate accurate, performance-optimized code, as they lack awareness of specifications the complexities programming....
<title>Abstract</title> Electrocardiogram (ECG)-based arrhythmia classification is vital for the early detection and diagnosis of heart diseases. However, raw ECG signals are often noisy, which poses challenges accurate classification. In this paper, we propose a novel approach that integrates discrete wavelet transform (DWT) signal denoising with an Attention-Enhanced Convolutional Neural Network-Bidirectional Gated Recurrent Unit (CNN-BiGRU) model Initially, DWT applied to remove noise...
