Dynamic Calibration of DEM Simulations Using Rotating Drum Experiments Using the Mean Absolute Error

Chemie Ingenieur Technik, EarlyView.
Calibrating DEM simulations is challenging due to unknown microscopic parameters. Rotating drum experiments are combined with image‐based analysis and Latin Hypercube Sampling (LHS). An area‐based Mean Absolute Error (MAE) enables reliable identification of optimal parameter sets.

Multiple Pulmonary Involvement in the Rapidly Progressive Evolution of Rheumatoid Arthritis

Diagnostics
A 66-year-old man, a 40-year smoker, was diagnosed with rheumatoid arthritis in 2018. He was treated for one year with methotrexate, and, later in 2020, he was diagnosed with interstitial pulmonary fibrosis.

A Centre-Stable Manifold for the Energy-Critical Wave Equation in R^3 in the Symmetric Setting [PDF]

, 2012
Consider the focusing semilinear wave equation in R^3 with energy-critical nonlinearity \partial_t^2 \psi - \Delta \psi - \psi^5 = 0, \psi(0) = \psi_0, \partial_t \psi(0) = \psi_1.

Coherent Forecasting of Realized Volatility

Journal of Forecasting, EarlyView.
ABSTRACT The QLIKE loss function is the stylized favorite of the literature on volatility forecasting when it comes to out‐of‐sample evaluation and the state of the art model for realized volatility (RV) forecasting is the HAR model, which minimizes the squared error loss for in‐sample estimation of the parameters.

Evaluation of the Shock Absorption Capacity of Polymeric Specimens Manufactured by 3D Printing

Macromolecular Symposia, EarlyView.
ABSTRACT In the current context, due to the accelerated development of additive manufacturing, parts made of polymeric materials such as polylactic acid (PLA) manufactured by 3D printing are increasingly used. Such applications can be used, for example, in situations involving dynamic loads, where the shock energy absorption properties are essential ...

The impact of alveolar hemorrhage on lung function tests

Archives of the Balkan Medical Union, 2020
Introduction. Alveolar hemorrhage syndrome is a severe condition, with a high-risk of death. A timely diagnosis and therapy may be life-saving. The “gold-standard” method for diagnosing alveolar hemorrhage is bronchoscopy with bronchiolo-alveolar lavage.

Investigation of the Critical Overhang Angle in Fused Filament Fabrication Technology

Macromolecular Symposia, EarlyView.
ABSTRACT In fused filament fabrication, overhangs are challenging because each deposited layer requires partial support from the previous layer. The frequently cited 45° guideline for unsupported printing originates from empirical practice and does not consistently represent process‐specific behavior.

Safety Evaluation of an Aqueous Root and Leaf Extract of Ashwagandha (Withania somnifera)

Phytotherapy Research, EarlyView.
Sensoril, an aqueous root and leaf extract of ashwagandha showed no evidence of mutagenicity in the in vitro Ames assay, was negative in the in vitro micronucleus, in vivo mammalian bone marrow chromosome aberration assays, and was well tolerated in the rat at up to 4000 mg/kg BW/day when administered orally for a period of 90 days. The data from these

Search and Passage Are Decoupled for Migrating Trout Kelts at Multi‐Exit Dam

River Research and Applications, EarlyView.
ABSTRACT Longitudinal and lateral river connectivity have been drastically reduced over time, with hydropower development as a major driver of fragmentation. While fishways are widely implemented to support upstream migration, downstream passage remains a major challenge.
