Critical Phenomena at the Antiferromagnetic Phase Transition of Azurite

open access: yes, 2012
We report on high-resolution acoustic, specific-heat and thermal expansion measurements in the vicinity of the antiferromagnetic phase transition at T_N = 1.88 K on a high-quality single crystal of the natural mineral azurite. A detailed investigation of

Considerations for Issues of Regression to the Mean and Contextual Effects in Clinical Trials for Pain in Rheumatic Diseases

open access: yesArthritis Care &Research, Accepted Article.
Recently, there has been growing discussion about how to best assess pain in clinical trials in rheumatic diseases. Reliable measurement of pain outcomes is essential for accurately determining the effectiveness of treatments. While pain intensity is the most common measure of change in pain trials, other pain‐related measures, such as pain ...

Random Quantum Ising Model with Three-Spin Couplings

open access: yesEntropy
We apply a real-space block renormalization group approach to study the critical properties of the random transverse-field Ising spin chain with multispin interactions.

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

Hyperoxia Induced Alteration of Chromatin Structure in Human Bone Marrow Derived Primary Mesenchymal Stromal Cells

open access: yesAdvanced Biology, EarlyView.
Chromatin, which organizes DNA, changes its structure to adapt to stress like high oxygen levels (hyperoxia), which can damage cells. Researchers developed a technique to observe these changes and found variability in how different parts of chromatin remodel.

Asymptotics of critical conditions in one combustion model

open access: yesВестник Самарского университета: Естественнонаучная серия
The work is devoted to solving the problem of critical conditions for an autocatalytic combustion model, taking into account the consumption of reagent and oxidizer.

Stability of the Griffiths phase in a 2D Potts model with correlated disorder

open access: yesCondensed Matter Physics, 2014
A Griffiths phase has recently been observed by Monte Carlo simulations in the 2D q-state Potts model with strongly correlated quenched random couplings.
