Clinician perspectives on infusion site-of-care shifts in pediatric inflammatory bowel disease: An anonymous national web-based survey. [PDF]

JPGN Rep
Abstract Commercial payers and pharmacy benefit managers use site‐of‐care and specialty drug distribution policies (including white bagging and brown bagging) that can redirect infusion‐based biologic therapies from hospital outpatient departments to alternate settings.

Wasteosomes accumulate in periventricular white matter hyperintensities and exhibit complex relationships with mixed pathology, sclerotic index, and perivascular space. [PDF]

Brain Pathol
In a mixed diagnostic cohort of pathologically diagnosed Alzheimer's disease, cerebrovascular disease, mixed pathology, and control tissue, we connected the histopathological wasteosome profile in periventricular (PV) brain sections to 7T FLAIR‐MRI confirmed PV white matter hyperintensities (WMHs), vascular stenosis and perivascular space size ...

Study on longitudinal nonlinear deformation of adjacent existing tunnels induced by deep foundation excavation [PDF]

Scientific Reports
The simplified calculation methods for predicting the longitudinal deformation of neighboring existing tunnels caused by deep foundation excavation in engineering practice all use linear foundation model to interact with tunnel structure, and less use of

Influence of Winkler-Pasternak Foundation on the Vibrational Behavior of Plates and Shells Reinforced by Agglomerated Carbon Nanotubes

Applied Sciences, 2017
This paper aims to investigate the effect of the Winkler-Pasternak elastic foundation on the natural frequencies of Carbon Nanotube (CNT)-reinforced laminated composite plates and shells. The micromechanics of reinforcing CNT particles are described by a

Bending and vibration behavior of functionally graded piezoelectric nanobeams considering dynamic flexoelectric and surface effects [PDF]

Scientific Reports
This paper develops a more comprehensive theoretical model for functionally graded material (FGM) piezoelectric nanobeams. The model incorporates a Winkler–Pasternak linear elastic foundation and fully accounts for the effects of dynamic flexoelectric ...

Investigation of deformation of existing tunnel due to above excavation unloading considering tunnel lateral response [PDF]

Scientific Reports
The safety of underlying metro tunnels is significantly compromised when the excavation of the overlying foundation pit is not properly conducted. Currently, research on the longitudinal deformation of tunnels induced by upper excavation typically relies

DDSurfer: A Weakly-Supervised Dual-Stream Deep Learning Framework for Cortical Surface Reconstruction From Diffusion MRI. [PDF]

Adv Sci (Weinh)
DDSurfer reconstructs cortical surfaces directly from diffusion MRI without requiring T1‐weighted scans. By fusing complementary microstructural features and learning diffeomorphic deformations, it efficiently generates accurate white matter and pial surfaces, improving geometric fidelity and morphometric reliability across datasets for robust surface ...

Analytical solution for deformation of an existing tunnel induced by shield tunnelling overcrossing in complex strata [PDF]

Scientific Reports
This study investigates the influence of new tunnel construction which traverses above existing shield tunnels on the vertical displacement behavior in complex strata. Through the introduction of state vectors for soil layers, the displacement and stress
