Design and analysis of tetra-port MIMO antenna for next generation vehicular communication [PDF]

open access: yesScientific Reports
The demand for advanced automotive applications necessitated the development of 5G/6G multiple-input-multiple-output (MIMO) antennas. This work presents a low-profile antenna resonating at 5.9 GHz, suitable for vehicle-to-vehicle communication ...

Current-mode Biquadratic Universal Filter Design with Two Terminal Unity Gain Cells

open access: yesRadioengineering, 2012
A grounded parallel lossy active inductor and two current-mode (CM) universal filters are presented in this paper. All the circuits use two voltage followers (VFs) and a current follower (CF).

Polarization-independent perfect metamaterial absorber for C, X and, Ku band applications

open access: yesJournal of Materials Research and Technology, 2021
In this paper, a polarization-independent perfect absorber with near-zero index metamaterial (NZIM) property is proposed. Conventional FR4 substrate without any lumped or substrate-embedded elements has been used with a unique patch of the swastika ...

An ultra high step‐up DC‐DC converter based on VMC, POSLLC, and boost converter

open access: yesIET Power Electronics, 2022
In this article, an ultra‐high step‐up DC‐DC converter has been proposed. The topology of the converter is a combination of a cascaded boost converter, positive output super lift Luo converter (POS LLC), and a voltage multiplier cell (VMC).

Optimizing the Therapeutic Window of Targeted Drugs in Oncology: Potency‐Guided First‐in‐Human Studies

open access: yesClinical and Translational Science, 2021
Many targeted therapies are administered at or near the maximum tolerated dose (MTD). With the advent of precision medicine, a larger therapeutic window is expected. Therefore, dose optimization will require a new approach to early clinical trial design.

Rechtsgeschichte – Geschichte der Evolution eines sozialen Systems [PDF]

open access: yesRechtsgeschichte - Legal History, 2002
1. Historiography is about the observation of changes. Even in a history of the moment, there has to be a before and an after. There is no history without event, without the difference perceived and described as "time".

Universal filter using unity-gain cells

open access: yesElectronics Letters, 1995
The authors propose the use of both current and voltage followers for implementation of a universal filter. The aim is to show how, by using only unity-gain cells as active components, a universal filter can be obtained with improved performance over classical filters.
