Near-infrared-II (NIR-II) dyes could be encapsulated by either exogenous or endogenous albumin to form stable complexes for deep tissue bioimaging.However, we still lack a complete understanding of the interaction mechanism dye@albumin complex.Studying this principle is essential guide efficient dye synthesis and develop NIR-II probes with improved brightness, photostability, etc. Methods: Here, screen test optical chemical properties fluorophores, systematically investigate binding sites...
The objective of this paper is to investigate potential satellite C-band synthetic aperture radar (SAR) in monitoring sugarcane growth southern China. This proposes a method map growing area and retrieve leaf index (LAI) different stages using ENVISAT Advanced SAR (ASAR) alternating polarization HH/HV data. temporal response ASAR data fields LAI was first analyzed the study area. analysis shows that have increasing trend with ratio HV HH has better correlation increase LAI. A theoretical...
Aiming at the irregularity of nonlinear signal and its predicting difficulty, a deep learning prediction model based on extreme‐point symmetric mode decomposition (ESMD) clustering analysis is proposed. Firstly, original data decomposed by ESMD to obtain finite number intrinsic functions (IMFs) residuals. Secondly, fuzzy c ‐means used cluster components, then belief network (DBN) predict it. Finally, reconstructed IMFs residuals are final results. Six kinds models compared, which DBN model,...
Sentinel lymph node (SLN) biopsy is the key diagnostic procedure to determine tumor metastasis and treatment plan.Current SLN has considerable drawbacks in that SLNs (both malignant normal) must be removed by navigation surgery, followed a time-consuming pathological examination.The selective, non-invasive, real-time diagnosis of metastatic status becoming essential.Methods: Here, we design two lanthanide-doped nanoparticles as pair NIR-II ratiometric fluorescence probes, one which...
In this paper, the problem of maximizing sum data rates all users in an intelligent reflecting surface (IRS)-assisted millimeter wave multicast multiple-input multiple-output communication system is studied. considered model, one IRS deployed to assist from a multi-antenna base station (BS) that are clustered into several groups. Our goal maximize rate by jointly optimizing transmit beamforming matrices BS, receive users, and phase shifts IRS. To solve non-convex problem, we first use block...
Ferroptosis, an emerging nonapoptotic, modulated cell death process characterized by iron accumulation and subsequent lipid peroxidation, has been intimately implicated in the development progression of ovarian cancer (OC). Daphnetin (Daph), a natural product isolated from Daphne Korean Nakai, exhibits anticancer efficacy against various solid tumors. However, specific role potential mechanism underlying Daph-mediated modulation ferroptosis OC cells remain elusive.
Solid tissue biopsy is fundamental in guiding surgeons during intraoperative and peri-operative management of cancer patients. However, conventional histopathologic methods depend heavily on the expertise trained pathologists, facing challenges accuracy efficiency. Methods: Here, we show that unbiased labeling proteins within sections using tumor-selective dyes enhances tumor-specific signals, enabling robust accurate differentiation tumors from normal tissues less than 45 min. This...
AbstractRice is the staple grain in China and accounts for about 42% of nation's food production. Most China's paddy rice production located southern provinces country where cloud cover frequent rain severely limit opportunities optical satellite acquisitions. The small field sizes, typical rice, also challenge exploitation data monitoring Synthetic aperture radar (SAR) sensors are able to successfully acquire under most atmospheric conditions, change backscatter, from emergence through crop...
Compared with the synthesis process of CMK-3 material, ordered mesoporous carbon (OMC) materials were successfully synthesized by simplifying steps. The silica/P123 composite material that had formed nanostructures was not filtered, washed, and calcined to form SBA-15 but it directly used as a hard template synthesize OMC materials. self-assembly block polymers (P123) in pore space removed carbonized partial source. agent (surfactant P123) part synthetic exhibited large volume, high specific...
With a focus on the particle pollutants surface of silicon carbide crystal materials, this paper establishes laser cleaning model for fine particles found in materials and proposes new nanosecond green method assisted by airflow, which can effectively remove microparticles oxide layer substrate surface.

Laser texturing is a relatively new multiprocess technique that has been used for machining 3D curved surfaces; it more flexible and efficient to create decorative texture on surfaces of injection molds so as improve the surface quality achieve cosmetic molded plastic parts. In this paper, novel method laser based 3-axis galvanometer scanning unit presented prevent mold from much distortion which often caused by traditional processes. The computer mapping technology developed presented....
Abstract In order to improve the fluorine removal performance of bauxite, effects different calcination temperatures and several acids (HCl, H 2 SO 4 , C O ) on bauxite were investigated. It was found that temperature 500°C modification had best performance. Under same experimental conditions, fluoride rate modified could reach 99.54%, which much higher than unmodified (52.69%). The adsorbent characterized by XRD, FTIR, BET, TG/DSC, XRF. influence addition amount adsorbent, initial...
This paper introduces applications of the Dempster–Shafer (D-S) data fusion technique in transportation system decision making. D-S inference is a statistics-based classification technique, and it can be used when sources contribute discontinuous incomplete information no single source produce an overwhelmingly high probability certainty for identifying most probable event. The captures combines contributed by using Dempster’s rule to find conjunction events determine highest associated...

Abstract In recent years, with a large number of distributed energy sources connected to the grid, distribution network has shown clear trend towards use power electronics. As conversion interface, stability converter's interaction grid received considerable attention. Adequate admittance (impedance) modeling three‐phase grid‐connected converter is prerequisite for analyzing and resonance characteristics system. Understanding internal mechanisms proposing effective solutions are crucial...
This paper is concerned with the low-rank approximation for large-scale nonsymmetric matrices. Inspired by classical Nystrom method, which a popular method to find symmetric positive semidefinite matrices, we explore an extension of approximate The proposed generalized column sketching and shows its advantages in accuracy speed without sacri cing stability. And numerical experiments will illustrate robustness our new methods finding desired matrix.
