CMOS Vector Modulator-Based Phase Shifter for Millimeter-Wave Transmitter [PDF]

Journal of Electromagnetic Engineering and Science
A D-band phase shifter for CMOS transmitters in a millimeter-wave imaging system is proposed based on vector modulator configuration. Depending on the phase control biasing, the output impedance variation of phase shifters at the millimeter-wave ...

All‐fibre phase shifter based on tapered fibre coated with MoWS2‐rGO

IET Optoelectronics, 2021
In this work, an all‐fibre phase shifter using tapered fibre coated with molybdenum tungsten disulfide ‐ reduced graphene oxide (MoWS2‐rGO) is demonstrated. The large evanescent field of tapered fibre allows MoWS2‐rGO to absorb injected light from a 1400‐

Bone and Soft Tissue Neoplasms in Infants Versus Older Children: A Report From the Cancer in Young People in Canada Program

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Infant bone and soft tissue neoplasms present distinct clinical challenges and lack large‐scale data to inform treatment decisions. This study aims to characterize bone and soft tissue neoplasms in infants in Canada and to compare their outcomes with those of older pediatric patients.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Proposing a Modified Switchable Schiffman Structure to Implement a Wideband and Low-Loss 4-bit Digital Phase Shifter

IEEE Access
This paper proposes a modified Schiffman structure to implement a wideband, low-loss 4-bit digital phase shifter. Here, low-cost positive intrinsic negative (PIN) diodes are used for electronically controlling the phase states of the phase shifter.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Ultra-Wideband 4-Bit Distributed Phase Shifters Using Lattice Network at K/Ka- and E/W-Band

IEEE Open Journal of the Solid-State Circuits Society
In this article, we introduce an ultra-wideband 4-bit distributed phase shifter using a lattice network. To achieve wider bandwidth, the proposed phase shifter employed an all-pass lattice network instead of the traditional low-pass ladder network. Seven

A TCAD study on the effect of process parameters on silicon optical phase shifter performance

Frontiers in Physics, 2023
On-chip integrated optical phase shifters are an important part of optical phase modulators. The performance of such modulators relies heavily on the phase shifter performance, which in turn depends on multiple process parameters.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
