Engineered surface strategies to manage dental implant‐related infections
Periodontology 2000, EarlyView.Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Realization of DVCCTA Based Versatile Modulator
Active and Passive Electronic Components, Volume 2014, Issue 1, 2014., 2014 A Differential Voltage Current Conveyor Transconductance Amplifier (DVCCTA) based versatile modulator is proposed which can work as an amplitude modulator, frequency modulator, delta modulator, and sigma delta modulator. The modulator operational scheme uses pulse generator as a core and its output is used as carrier signal.

An optimized transform and quantization scheme for HEVC intra lossless coding
Engineering Reports, Volume 6, Issue 11, November 2024.In this article, we propose an Intra lossless coding scheme based on transformation and quantization for High Efficiency Video Coding (HEVC). The initial residual block is divided into two parts: the coefficient block and the error block. The proposed mode is combined with the transform bypass mode to achieve better coding efficiency at transform units

Analysis and Design of Network‐Based Control Systems with Binary Modulation
Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014 Network‐based control systems have been emerging technologies in control and computer communication fields over the past decade. This paper focuses on the analysis and design of network‐based control systems with binary modulation. First, it is shown that different modulations can result in different delays which are inevitable in network‐based control
