Viscoacoustic Full Wavefield Migration With Tomographic Q Estimation

open access: yesGeophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Seismic wave propagation in the Earth's subsurface is influenced by anelastic attenuation, which causes energy loss and waveform distortion, degrading image resolution. This effect, quantified by the quality factor (Qf${{\textit {Q}}_f}$), is particularly pronounced in settings such as carbon capture and storage and near‐surface studies, where

Bounds on Hermitian-Toeplitz determinant for starlike, convex and bounded turning functions associated with the exponential function

open access: yesМатематичні Студії
In the article we derive sharp bounds for the third-order Hermitian-Toeplitz determinant of starlike and convex functions associated with the exponential function, as well as for their inverse classes.

The effect of labor epidural analgesia on uterine activity using electrohysterography monitoring: A follow‐up study

open access: yesActa Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 5, Page 912-921, May 2026.
Epidural analgesia during the first stage of labor shows no clinically relevant changes in uterine contraction frequency and duration, but it is associated with a significant reduction in uterine intensity. Their clinical implications need further research.

Quantum Time‐Marching Algorithms for Solving Linear Transport Problems Including Boundary Conditions

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 8, 30 April 2026.
ABSTRACT This article presents the first complete application of a quantum time‐marching algorithm for simulating multidimensional linear transport phenomena with arbitrary boundaries, whereby the success probabilities are problem intrinsic. The method adapts the linear combination of unitaries algorithm to block encode the diffusive dynamics, while ...

Beyond the Non‐Hermitian Skin Effect: Scaling‐Controlled Topology from Exceptional‐Bound Bands

open access: yesAdvanced Science, Volume 13, Issue 20, 9 April 2026.
ABSTRACT We establish a novel mechanism for topological transitions in non‐Hermitian systems that are controlled by the system size. Based on a new paradigm known as exceptional‐bound (EB) band engineering, its mechanism hinges on the unique critical scaling behavior near an exceptional point, totally unrelated to the well‐known non‐Hermitian skin ...

Efficacy and Safety of Zonisamide Addition in Children With Developmental Epileptic Encephalopathy/Epileptic Encephalopathy: A Real‐World Study

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.
Adjunctive zonisamide provides sustained efficacy and favorable tolerability in children with DEE/EE, including young children < 6 years and highly drug‐resistant cases. Gender and prior treatment history predict long‐term efficacy, supporting its reliable risk–benefit profile for refractory epilepsy.
