High-Gain Magnetized Inertial Fusion

Physical Review Letters, 2012
Magnetized inertial fusion (MIF) could substantially ease the difficulty of reaching plasma conditions required for significant fusion yields, but it has been widely accepted that the gain is not sufficient for fusion energy. Numerical simulations are presented showing that high-gain MIF is possible in cylindrical liner implosions based on the MagLIF ...

An Adaptive Five‐Element Array Antenna Based on Miniaturised Polarisation‐Insensitive Absorptive Metamaterial for Anti‐Jamming Applications

IET Microwaves, Antennas & Propagation
This paper proposes a polarisation‐insensitive absorptive metamaterial unit cell that achieves a perfect absorption of circularly polarised (CP) incident waves. To overcome the miniaturisation limitations inherent in conventional metamaterial designs, an

High-Gain Dual-Band Dual-Sense Circularly Polarized Spiral Series-Fed Patch Antenna

IEEE Open Journal of Antennas and Propagation, 2022
This paper demonstrates a dual-band circularly polarized (CP) two-dimensional (2D) series-fed patch array antenna. The CP rotating sense in each band is opposite to each other, which makes them well-suited for the downlink and uplink in satellite ...

A Quality Improvement Initiative to Standardize Pneumocystis jirovecii Pneumonia Prophylaxis in Pediatric Patients With Solid Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric patients with extracranial solid tumors (ST) receiving chemotherapy are at an increased risk for Pneumocystis jirovecii pneumonia (PJP). However, evidence guiding prophylaxis practices in this population is limited. A PJP‐related fatality at our institution highlighted inconsistent prescribing approaches and concerns about

A Compact Wideband Circular Polarized Fabry-Perot Antenna Using Resonance Structure of Thin Dielectric Slabs

IEEE Access, 2018
A wideband small-footprint circularly polarized Fabry-Perot resonator antenna is presented in this paper. The design employs a partial reflecting surface (PRS) consisting of thin homogeneous dielectric slabs separated by a small air gap.

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Sickle cell disease (SCD) and asthma share a complex relationship. Although estimates vary, asthma prevalence in children with SCD is believed to be comparable to or higher than the general population. Determining whether SCD confers an increased risk for asthma remains challenging due to overlapping symptoms and the ...

Pazopanib Combined With Vincristine and Irinotecan in Relapsed Wilms Tumor: Encouraging Outcomes in a Heavily Pretreated Pediatric Cohort

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background While Wilms tumor (WT) typically has a favorable prognosis, relapsed cases—especially those with high‐risk histology—remain therapeutically challenging after intensive frontline therapy. The combination of vincristine and irinotecan has demonstrated activity in pediatric solid tumors, and pazopanib, a multi‐targeted tyrosine kinase ...

Compact High Gain Wideband Circularly Polarized Non-Uniform Metasurface Antenna Through Improved Mode Coupling

IEEE Open Journal of Antennas and Propagation
A wideband, high gain circularly polarized (CP) metasurface (MTS) based slot antenna is presented. The designed nonuniform slots provide wider bandgap regions and extra degree of freedom in tuning to obtain wider impedance bandwidth through improved mode

Analysis and design of Minkowski-like fractal antennas

Dianzi Jishu Yingyong, 2019
In order to achieve that an antenna works in ISM2.4G(2.4～2.483 5 GHz), Bluetooth,GPS,WLAN(2.4～2.48 GHz) and other multi-frequency band at the same time，the Minkowski fractal microstrip antenna based on the fractal theory is designed, and the original ...
