Ultrasonic-Vibration-Assisted Waterjet Drilling of [0/45/−45/90]2s Carbon-Fiber-Reinforced Polymer Laminates

open access: yesMicromachines, 2023
The pure waterjet (WJ) drilling process of carbon-fiber-reinforced polymer (CFRP) laminates causes damage, such as tears and delamination, leading to poor-quality hole-wall.

Amplitude and phase variation of point processes [PDF]

open access: yes, 2016
We develop a canonical framework for the study of the problem of registration of multiple point processes subjected to warping, known as the problem of separation of amplitude and phase variation. The amplitude variation of a real random function $\{Y(x):

Early metastasis is characterized by Gr1+ cell dysregulation and is inhibited by immunomodulatory nanoparticles

open access: yesMolecular Oncology, EarlyView.
Breast cancer metastasis is associated with myeloid cell dysregulation and the lung‐specific accumulation of tumor‐supportive Gr1+ cells. Gr1+ cells support metastasis, in part, through a CHI3L1‐mediated mechanism, which can be targeted and inhibited with cargo‐free, polymeric nanoparticles.

On amplitude zeros at threshold

open access: yes, 1992
The occurrence of zeros of 2 to n amplitudes at threshold in scalar theories is studied. We find a differential equation for the scalar potential, which incorporates all known cases where the 2 to n amplitudes at threshold vanish for all sufficiently ...

Model selection for amplitude analysis [PDF]

open access: yes, 2015
Model complexity in amplitude analyses is often a priori under-constrained since the underlying theory permits a large number of possible amplitudes to contribute to most physical processes.

Accurate numerical solutions of conservative nonlinear oscillators

open access: yesNonlinear Engineering, 2014
The objective of this paper is to present an investigation to analyze the vibration of a conservative nonlinear oscillator in the form u" + lambda u + u^(2n-1) + (1 + epsilon^2 u^(4m))^(1/2) = 0 for any arbitrary power of n and m.

Optical Analysis of the Impact Transmission in Steel Sheet Arrays with Bolted-Type Joints

open access: yesApplied Sciences, 2023
This research leads with the analysis of a structural joint. Different arrays of steel sheets were joined using bolts. The structures were built in a metallic box filled with Granitic 0/3 sand.

Cutting the Coon amplitude

open access: yesJournal of High Energy Physics, 2023
Abstract The Coon amplitude is a q-deformed generalization of the Veneziano amplitude exhibiting a semi-infinite sequence of poles that converge on an accumulation point, from which a branch cut emerges. A number of recent papers have provided compelling evidence that the residues of this amplitude satisfy the positivity ...

Biophysical characterization and ion transport with cell‐based and proteoliposome reconstitution assays of invertebrate K+‐Cl− cotransporters

open access: yesFEBS Open Bio, EarlyView.
The K+‐Cl− cotransporters (KCCs) facilitate the symport of ions across the plasma membrane. They participate in physiological processes including neuronal regulation. Here, we characterized KCCs from Drosophila and Hydra vulgaris. Comparative analyses of transporters provide insights into the mechanism of KCC ion transport, regulation, and evolution ...

Measuring phase-amplitude coupling between neuronal oscillations of different frequencies.

open access: yesJournal of Neurophysiology, 2010
Neuronal oscillations of different frequencies can interact in several ways. There has been particular interest in the modulation of the amplitude of high-frequency oscillations by the phase of low-frequency oscillations, since recent evidence suggests a
