Topology optimization of multiphase material structures under design dependent pressure loads [PDF]
International Journal for Simulation and Multidisciplinary Design Optimization, 2009 In this paper, design-dependent pressure loads are addressed for topology optimization problems of multiphase material structures. The modeling of unidirectional load distribution with respect to the material density is studied and mathematical ...

Influence of Load Modeling on the Cost of Ensuring Stability Using TSCOPF
IEEE Access, 2023 Load modeling significantly impacts the time-domain response of power systems in transient stability studies but this effect is often underestimated in Transient Stability Constrained Optimal Power flow (TSCOPF) studies.

Shear stress fluctuations in the granular liquid and solid phases
, 2005 We report on experimentally observed shear stress fluctuations in both granular solid and fluid states, showing that they are non-Gaussian at low shear rates, reflecting the predominance of correlated structures (force chains) in the solidlike phase ...

Molecular Oncology, EarlyView.Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Use of cohesive elements in fatigue analysis [PDF]
, 2008 Cohesive laws describe the resistance to incipient separation of material surfaces. A cohesive finite element is formulated on the basis of a particular cohesive law.

Molecular 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 ...

Regression-SARIMA modelling of daily peak electricity demand in South Africa
Journal of Energy in Southern Africa, 2017 In this paper, seasonal autoregressive integrated moving average (SARIMA) and regression with SARIMA errors (regression-SARIMA) models are developed to predict daily peak electricity demand in South Africa using data for the period 1996 to 2009.

Transformation of load-settlement curve based on load transfer at pile-soil interface
Yantu gongcheng xuebao, 2021 The self-anchoring test is a new method to detect the bearing capacity of pile foundation.The indoor model tests and the numerical simulation are used to explore the difference of the Q-S curves between the static load tests and the self-anchoring tests,

A fixed-point approximation for a routing model in equilibrium [PDF]
, 2013 We use a method of Luczak (arXiv:1212.3231) to investigate the equilibrium distribution of a dynamic routing model on a network. In this model, there are $n$ nodes, each pair joined by a link of capacity $C$. For each pair of nodes, calls arrive for this

Molecular Oncology, EarlyView.Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...
