Lamb Waves-Based Computation of Impact Echo Thickness Resonant Frequency: Theory Development and Case Study

open access: yesAdvances in Civil Engineering
The traditional equation of impact echo (IE) thickness resonant frequency upon P-wave reflections is developed based on P-wave velocity and thickness of the plate and a geometric correction factor.

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

open access: yesMolecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Numerical Approach for the Frequency-Weighted Hankel-Norm Approximation

open access: yes, 2001
We derive new projection formulas for the model reduction method based on the frequency-weighted Hankel norm approximation (FWHNA). These formulas extend the applicability of the FWHNA method to frequency weights expressed as antistable right/left ...

A new principle technic for the transformation from frequency domain to time domain

open access: yesAIP Advances, 2017
A principle technic for the transformation from frequency domain to time domain is presented. Firstly, a special type of frequency domain transcendental equation is obtained for an expected frequency domain parameter which is a rational or irrational ...

Estimate of intense rainfall equation parameters for rainfall stations of the Paraíba State, Brazil

open access: yesPesquisa Agropecuária Tropical, 2017
Rainfall is the primary water source for hydrographic basins. Hence, the quantification and knowledge of its temporal and spatial distribution are indispensable in dimensioning hydraulic projects.

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

open access: yesMolecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Numerical solution of Rayleigh-Lamb frequency equation for real, imaginary and complex wavenumbers

open access: yesMATEC Web of Conferences, 2018
Guided waves, especially Lamb waves or shear-horizontal waves, are widely used types of waves for ultrasonic inspection of large structures. Well known property of guided waves is their dispersive character, which means that the propagation velocity of ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Numerical studies of localized wave fields governed by the Raman-extended derivative nonlinear Schrodinger equation

open access: yes, 2007
. Using a stable pseudospectral multi-domain method we investigate the dynamics of localized wave fields in the Extended Derivative Nonlinear Schrodinger (EDNLS) equation, with a particular emphasis on the critical mass and structure of the initial ...
