Bayesian Optimization of Grayscale Patterns for Layer‐Height Accuracy in Projection Multi‐Photon 3D Printing

open access: yesLaser &Photonics Reviews, EarlyView.
Bayesian optimization combined with in situ quantitative phase imaging enables autonomous correction of layer‐height deviations in projection multi‐photon lithography. By jointly tuning model parameters and grayscale exposure settings, the method achieves more uniform and accurate layers within 300 prints, offering a fast, data‐efficient route to ...

SelExNet: A Self‐Supervised Physics‐Informed Framework for Multi‐Channel Joint RF and Gradient Waveform Optimization in 2D Spatially Selective Excitation

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To introduce SelExNet: a self‐supervised framework for two‐dimensional spatially selective excitation that jointly optimizes radiofrequency (RF) pulses and gradient waveforms, and extends to multi‐channel transmission MRI. Methods Building on prior RF‐only and joint RF‐gradient optimization approaches, SelExNet couples neural RF and ...

Collaborative Reconstruction of PROPELLER‐EPI Data Using POCSMUSE (CORPUSE) for High‐Fidelity Diffusion MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a reconstruction framework for DW‐PROPELLER‐EPI that improves image quality and SNR efficiency under per‐blade acceleration while minimizing EPI‐related artifacts, enabling high‐resolution diffusion‐tensor imaging (DTI) with fewer blades.

Vibration Attenuation of Cantilever Beam Using Electromagnetic Delayed Feedback

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study presents a combined analytical and numerical investigation of a single‐input single‐output delayed feedback controller designed to suppress vibrations in a cantilever beam actuated by an electromagnet positioned beneath its free end. An analytical model was developed using the linearized equation of motion for a transversely excited

Centroid-Induced Ranking of Triangular Picture Fuzzy Numbers and Applications in Decision-Making

open access: yes
This paper proposes the concept of a centroid for picture fuzzy numbers and particularly for triangular picture fuzzy numbers. The concept allows the implementation of a ranking function for the triangular picture fuzzy numbers, which has the advantage ...

Different Stakeholders, Different Pathways: How Capacity Profiles Shape Managerial Priorities for Beneficiaries and Staff in Decision‐Making

open access: yesNonprofit Management and Leadership, EarlyView.
ABSTRACT This study investigates how combinations of organizational capacities shape nongovernmental organization (NGO) managers' prioritization of staff and beneficiaries. While stakeholder theory identifies which stakeholders' interests attract attention, it offers limited guidance on how managers ultimately prioritize among stakeholders in decision ...

3D effects of seawater on electrical resistivity tomography near shorelines—Challenges and possible solutions inferred from synthetic and field data

open access: yesNear Surface Geophysics, EarlyView.
Abstract Electrical resistivity tomography (ERT) is one of the most widely used geophysical techniques for hydrogeological questions, such as investigating the groundwater transition zone between land and sea. The interpretation of 2D coast‐parallel ERT profiles is challenging because most of the electrical current flows through the highly conductive ...

Fostering Women's Political Leadership Through Government Accountability: Evidence From OECD Countries

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT Women remain significantly underrepresented in political leadership worldwide. This study examines how different combinations of government accountability mechanisms enhance women's political representation (WPR) as a pathway to leadership in 30 OECD countries.
