Vibration reduction method using passive control of wave propagation by a neutralizer

Nihon Kikai Gakkai ronbunshu, 2019
On recent machine structures, the size of subsystems is far smaller than the whole structure. Therefore, the compliance of a subsystem is dominated by a rigid body mode at the frequency of interest.

CORRECTION OF MASS-LOADING EFFECTS OF ACCELEROMETERS ON THE MEASURED FRFs USING OPTIMIZED MASS CHANGE ALGORITHM [PDF]

مجله مدل سازی در مهندسی, 2012
Modal testing is a developing expertise in the field of structural dynamics. However, in practice the models that are produced by modal testing procedure face different errors. One of the sources of error is mass-loading effects of accelerometers.

Venetoclax‐Based Therapy as a Bridge to Hematopoietic Stem Cell Transplantation in Relapsed or Refractory Pediatric Acute Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Relapsed and/or refractory (R/R) pediatric acute leukemia carries a dismal prognosis, largely driven by chemoresistance to conventional salvage therapy. The BH3‐mimetic venetoclax, combined with chemotherapy or hypomethylating agents, has demonstrated efficacy in small clinical trials.

Estimating the noise reduction effect of the Helmholtz resonator using a two-degree-of-freedom mass-spring-damping model

Nihon Kikai Gakkai ronbunshu, 2016
To reduce noise, Helmholtz resonators are widely used in internal-combustion engine intake systems, in the rocket engine's combustion chambers and building wall materials.

Language, Culture, and Cancer: Qualitative Insights Into Communication Disparities Among Spanish‐Speaking Caregivers of Children With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Latino children are projected to make up nearly one‐third of United States (US) children by 2060, and many of their caregivers speak Spanish. Prior survey research has documented communication difficulties for Spanish‐speaking caregivers of children with cancer, but contemporary qualitative data are limited.

Biphasic Clinical Course of Pediatric Cytomegalovirus‐Associated Immune Thrombocytopenia: Early Poor Treatment Response but Favorable Long‐Term Outcomes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cytomegalovirus (CMV) is a recognized trigger of immune thrombocytopenia (ITP); however, its incidence and impact on disease course in children remain controversial. Therefore, we aimed to characterize the clinical course of pediatric patients with CMV‐associated ITP.

A Spatial-Frequency Approach to Point-Wise Frequency Response Function Estimation with Digital Image Correlation

Applied Sciences
The use of digital image correlation for modal analysis is becoming an appealing option thanks to its non-contact and full-field measurement process. However, frequency response function (FRF) estimation can be challenging due to the limited number of ...
