Curvature-Controlled Polarization in Adaptive Ferroelectric Membranes

Posted by klaurent Delft

Kavli Affiliate: Andrea D. Caviglia | Summary:In this study, we explore the ferroelectric domain structure and mechanical properties of PbTiO$_3$-based membranes, which develops a well-ordered and crystallographic-oriented ripple pattern upon release from their growth substrate. The ferrolectric domain structure of the PbTiO$_3$ layer was examined at various length scales using optical second harmonic generation, piezoresponse […]

Prismatic-Bending Transformable (PBT) Joint for a Modular, Foldable Manipulator with Enhanced Reachability and Dexterity

Posted by dbos Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Jianshu Zhou, Junda Huang, Boyuan Liang, Xiang Zhang, Xin Ma | Summary: Robotic manipulators, traditionally designed with classical joint-link articulated structures, excel in industrial applications but face challenges in human-centered and general-purpose tasks requiring greater dexterity and adaptability. To address these challenges, we propose the Prismatic-Bending Transformable […]

Effective Multiple Scattering Correction for Accurate Quantitative OCT

Posted by dbos Hopkins

Kavli Affiliate: Xingde Li | Authors: Cheng-Yu Lee and Xingde Li | Summary: We present an effective approach to compensate for multiple scattering effects in Quantitative Optical Coherence Tomography (qOCT) imaging, with the goal of accurately extracting tissue attenuation coefficients, which is crucial for precise clinical diagnosis. In clinical practice, especially for intra-operative imaging, an […]

The THESAN-ZOOM project: central starbursts and inside-out quenching govern galaxy sizes in the early Universe

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | Summary:We explore the evolution of galaxy sizes at high redshift ($3 < z < 13$) using the high-resolution THESAN-ZOOM radiation-hydrodynamics simulations, focusing on the mass range of $10^6,mathrmM_odot < mathrmM_ast < 10^10,mathrmM_odot$. Our analysis reveals that galaxy size growth is tightly coupled to bursty star formation. Galaxies above the star-forming […]

Measuring photo-ionization rate and mean free path of HeII ionizing photons at $2.5 leq z leq 3.6$: Evidence for late and rapid HeII reionization Part-II

Posted by klaurent Cambridge

Kavli Affiliate: Martin Haehnelt | Summary:We present measurements of the spatially averaged HeII photo-ionization rate ($langle Γ_rm HeII rangle$), mean free path of HeII ionizing photons ($λ_rm mfp, HeII$), and HeII fraction ($f_rm HeII$) across seven redshift bins within the redshift range $2<z<4$. The measurements are obtained by comparing the observed effective optical depth distribution […]
