Longer Acting Injectable: Continuous, Linear Release of a Progestin Contraceptive From an Oxidized Porous Silicon Host

open access: yesAdvanced Healthcare Materials, EarlyView.
Progestin drugs are loaded into a mesoporous silicon dioxide host by melt‐infiltration. Drugs that decompose at or close to their melting point can be loaded by the addition of cholesterol, which acts as a melting point suppressor. High mass loading of the drug is achieved, and dissolution of the composite is controlled by the nanoscale properties of ...

分数阶傅里叶变换在轴承故障诊断中的应用

open access: yesJournal of Harbin University of Science and Technology, 2017
In fault diagnosis of rolling bearings,the fault signal is easy to be interfered by the ambient noise, Therefore,an approach based on Fractional Fourier Transform( FRFT) is studied in this research to collect valid data of rolling bearing fault.

Systematic Comparison of Commercial Uranyl‐Alternative Stains for Negative‐ and Positive‐Staining Transmission Electron Microscopy of Organic Specimens

open access: yesAdvanced Healthcare Materials, EarlyView.
Negative‐ and positive‐staining TEM is essential for rapid nanometer‐resolution characterization of organic specimens ranging from nanoparticles to cells. Uranyl salts are widely used negative‐/positive‐stains but are radioactive and highly toxic to users and the environment.

Peptide Display Directed Assembly of Biopolymer Core–Silica Shell Particles

open access: yesAdvanced Healthcare Materials, EarlyView.
Bacterial cells are engineered to produce biopolyester particles displaying peptides mediating growth of silica. Peptide‐coated biopolyester particles are treated with silica precursors and silica shell formation is studied. Transmission electron microscopy shows silica‐coated BPs which are formed after the silicification treatment. Characterization of

Robust Fractional Low-Order Multiple Window STFT for Infinite Variance Process Environment

open access: yesIET Signal Processing
Mechanical fault vibration signal is a typical non-Gaussian process, they can be characterized by the infinite variance process, and the noise within these signals may also be the process in complex environments.

Albumin Corona Overturns Long‐Acting Behaviors of Myristic Acid‐Conjugated Quetiapine Nanosuspension

open access: yesAdvanced Healthcare Materials, EarlyView.
Albumin corona alters surface properties and enhances colloidal stability by overturning pH responsiveness and nano‐aggregation behaviors of long‐acting myristic acid‐conjugated quetiapine nanosuspensions (QMN), resulting in accelerated in vitro and in vivo drug release.

Robust image watermarking using ant colony optimization and fast generic radial harmonic Fourier moment calculation

open access: yesIET Image Processing
In open networks, the geometric deformation and common image processing are common image manipulation modes, which pose a great challenge in robust watermarking. To improve the robustness of GRHFM‐based watermarking, a watermarking algorithm based on the
