Acoustic wavefront manipulation via transmission-type labyrinth structure
Frontiers in Physics, 2022 In this work, a transmission-type labyrinth structure (LS) is proposed to construct subwavelength acoustic functional metasurfaces, through which various desirable acoustic wavefront manipulation can be achieved in a broadband from 2,700 Hz to 3,900 Hz ...

3-D Printed Lattice Core for Wide Angle Scanning Radome at X-Band
IEEE Access, 2023 In this paper, we introduce a 3-D printed lattice core for wide-angle scanning radome operating in the X-band. We explain the fundamental design methodology of the sandwich structure for radome and outline the technique to represent the 3-D printed core ...

On solving periodic Riccati equations
, 2008 Numerically reliable algorithms to compute the periodic non-negative definite stabilizing solutions of the periodic differential Riccati equation (PRDE) and discrete-time periodic Riccati equation (DPRE) are proposed. For the numerical solution of PRDEs,

Известия высших учебных заведений России: РадиоэлектроникаIntroduction. This paper presents a procedure for synthesis of phase-correcting elements (PCE) based on band-pass filter using specialized software developed for these purposes. The amplitude response of the synthesized PCE and LC-filters based on lumped

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.

Noise Attenuation Performance of a Helmholtz Resonator Array Consist of Several Periodic Parts
Sensors, 2017 The acoustic performance of the ducted Helmholtz resonator (HR) system is analyzed theoretically and numerically. The periodic HR array could provide a wider noise attenuation band due to the coupling of the Bragg reflection and the HR’s resonance ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...
