RBAD: A Dataset and Benchmark for Retinal Vessels Branching Angle Detection.

IEEE EMBS Int Conf Biomed Health Inform

November 2024

School of Computing and Augmented Intelligence, Arizona State University.

Detecting retinal image analysis, particularly the geometrical features of branching points, plays an essential role in diagnosing eye diseases. However, existing methods used for this purpose often are coarse-level and lack fine-grained analysis for efficient annotation. To mitigate these issues, this paper proposes a novel method for detecting retinal branching angles using a self-configured image processing technique.

Background: For patients with drug-resistant focal epilepsy, surgical resection of the epileptogenic zone (EZ) is an effective treatment to control seizures. Accurate localization of the EZ is crucial and is typically achieved through comprehensive presurgical approaches such as seizure semiology interpretation, electroencephalography (EEG), magnetic resonance imaging (MRI), and intracranial EEG (iEEG). However, interpreting seizure semiology is challenging because it heavily relies on expert knowledge.

Nanoconfined Metal Halide Perovskite Crystallization within Removable Polymer Scaffolds.

Cryst Growth Des

May 2025

Molecular Design Institute, Department of Chemistry, New York University, New York, New York 10003, United States.

Nanoconfining crystallization to access metastable polymorphs and prescribe crystal orientations typically involves filling inert nanoporous scaffolds with target compounds, resulting in isolated nanocrystals. Such crystal-scaffold composites are unsuitable for optoelectronic devices that require interconnected crystalline pathways for charge transport. Here, we reverse the order of fabricating crystal-scaffold composites by first electrospinning interconnected networks of amorphous methylammonium lead iodide (MAPbI) precursor nanofibers, then introducing a poly(methyl methacrylate) (PMMA) scaffold by spin coating from an antisolvent for MAPbI.

Optically Triggered Nucleation Eliminates Hydration Hysteresis in Swelling Minerals.

Langmuir

May 2025

Lawrence Berkeley National Laboratory, CA, 1 Cyclotron Rd, Berkeley 94720, California, United States.

Hydration hysteresis is a ubiquitous feature of water exchange between porous solids and humid vapors. Whether one or both of the hydration hysteresis loop branches is metastable remains debated due to the many possible hydration mechanisms that can cause hysteresis. Here, we show that both endothermic and exothermic phase transitions among hydration states in smectites, model compliant porous media, can be optically activated during both hydration and dehydration, indicating that both branches are metastable.

Quantum Synchronization via Active-Passive Decomposition Configuration: An Open Quantum-System Study.

Entropy (Basel)

April 2025

Center for Quantum Science and Engineering, and Department of Physics, Stevens Institute of Technology, Hoboken, NJ 07030, USA.

In this paper, we study the synchronization of dissipative quantum harmonic oscillators in the framework of a quantum open system via the active-passive decomposition (APD) configuration. We show that two or more quantum systems may be synchronized when the quantum systems of interest are embedded in dissipative environments and influenced by a common classical system. Such a classical system is typically termed a controller, which (1) can drive quantum systems to cross different regimes (e.

Operational Work Fluctuation Theorem for Open Quantum Systems.

Phys Rev Lett

April 2025

TUD Dresden University of Technology, Institute of Theoretical Physics, 01062, Dresden, Germany.

The classical Jarzynski equality establishes an exact relation between the stochastic work performed on a system driven out of thermal equilibrium and the free energy difference in a corresponding quasistatic process. This fluctuation theorem bears experimental relevance, as it enables the determination of the free energy difference through the measurement of externally applied work in a nonequilibrium process. In the quantum case, the Jarzynski equality only holds if the measurement procedure of the stochastic work is drastically changed: it is replaced by a so-called two-point measurement scheme that requires the knowledge of the initial and final Hamiltonian and therefore lacks the predictive power for the free energy difference that the classical Jarzynski equation is known for.

Objective: Healthcare data provides a unique opportunity to learn causal relationships but the largest datasets, such as from hospitals or intensive care units, are often observational and do not standardize variables collected for all patients. Rather, the variables depend on a patient's health status, treatment plan, and differences between providers. This poses major challenges for causal inference, which either must restrict analysis to patients with complete data (reducing power) or learn patient-specific models (making it difficult to generalize).

A method for simulating electrorheological (ER) fluids is developed using LAMMPS (large-scale atomic, molecular massively parallel simulator) molecular dynamics simulations, aiming to model and analyze the microstructure and rheological behavior of ER fluids under an electric field. The results demonstrate that our simulation accurately captures the microstructural changes in ER fluids, and the simulation data show an impressively high level of consistency when compared directly with experimental data. The main innovation lies in our simultaneous consideration of dipole interactions, harmonic effects of ER particles, and the contact effect of electrode plates.

Large-gap peripheral nerve injuries (PNI) are often treated with autografts, allografts, or synthetic grafts to facilitate nerve regeneration, but these options are often limited in their availability or functionality. To address these issues, we developed ionically conductive (IC) nerve guidance conduits (NGCs) of sufficient biodegradability, mechanical strength, and bioactivity to support large-gap nerve regeneration. These chitosan-based NGCs release 4-aminopyridine (4-AP) from embedded halloysite nanotubes, and the NGC's IC properties enable transcutaneous electrical stimulation (ES) without invasive electrodes.

The collapse of a mine pillar is a catastrophic event with great consequences for a mining operation. In spite of the low probability of occurrence for a pillar collapse in comparison to other ground control instability issues, these consequences make these events high risk. Therefore, the design of these structures should be considered from a risk perspective rather than from a factor-of-safety deterministic approach, as it has been traditionally done.
