Basis Functions for a Transient Analysis of Linear Commensurate Fractional-Order Systems

Algorithms, 2023
In this paper, the possibilities of expressing the natural response of a linear commensurate fractional-order system (FOS) as a linear combination of basis functions are analyzed.

Adaptor protein CIN85 potentiates the motility of osteosarcoma cells via the Akt/mTOR and MMP2‐COL3A1 axis

Molecular Oncology, EarlyView.
CIN85 is highly expressed in osteosarcoma, particularly in metastatic lesions. Its overexpression increases cell migration and Matrigel invasion, while silencing CIN85 suppresses these behaviors. Transcriptome analysis shows that CIN85 regulates MMP2, COL3A1, and Akt/mTOR signaling. Targeting these pathways reverses CIN85‐induced motility, highlighting

Critical response of a single-degree-of-freedom system with bilinear hysteresis and viscous damping under triple impulse

Frontiers in Built Environment
A triple impulse is used as a mathematical model of forward-directivity inputs, which are fault-normal components of near-fault earthquake ground motions. In this paper, two types of the triple impulse input are employed.

Longitudinal genome‐wide aneuploidy measurements in circulating cell‐free DNA to predict lack of benefit from pembrolizumab in patients with metastatic urothelial cancer

Molecular Oncology, EarlyView.
Many patients with urothelial cancer do not benefit from treatment with pembrolizumab, while at risk of severe side effects. Changes in the levels of circulating tumor DNA early during treatment, measured by a simple and affordable assay that can be easily implemented in the clinic, can be used as a prognostic tool to identify these patients.

Surrogate impulse ground motion for practical simulation of critical nonlinear structural responses

Frontiers in Built Environment
Impulse-based representations of earthquake ground motions provide an efficient framework for evaluating critical nonlinear structural responses. However, the direct use of ideal impulse ground motions expressed by Dirac’s delta function may excite all ...

Effect of High-k Oxide on Double Gate Transistor Embedded in RF Colpitts Oscillator [PDF]

Журнал нано- та електронної фізики, 2016
The Linear Time Variant (LTV) model of phase noise is considered. It is based on the Impulse Sensitivity Function (ISF) which describes carefully the sensitivity of an oscillator to a parasite impulse current injection in different nodes of the circuit.

Investigation of the Physical Mechanism of Acoustic Attenuation in Viscous Isotropic Solids

Micromachines, 2022
The traditional acoustic attenuation coefficient is derived from an analogy of the attenuation of an electromagnetic wave propagating inside a non-ideal medium, featuring only the attenuation of wave propagation. Nonetheless, the particles inside viscous

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

EFFECT OF SHOCKS OF AGRICULTURAL TERMS OF TRADE (TOT) ON SOME AGRICULTURAL INDICATORS IN IRAQ FOR THE PERIOD (1990 - 2019)

The Iraqi Journal of Agricultural science
This study aimed to investigate the impact of agricultural TOT shocks and the strength of their effects on some indicators of the agricultural sector. The research uses VAR, Variance decomposition and IRF approaches.

A joint impulse response function for vector autoregressive models

Empirical Economics, 2020
AbstractMany applications call for measuring the response due to shocks from several variables at once. We introduce a joint impulse response function (jIRF) that is independent of the order of the variables and allows for simultaneous shocks from multiple variables in the VAR, rather than one at a time as in the generalized IRF.
