Outermost Cationic Surface Charge of Layer‐by‐Layer Films Prevents Endothelial Cells Migration for Cell Compartmentalization in Three‐Dimensional Tissues

open access: yesAdvanced Science, EarlyView.
A nanometer‐sized artificial basement membrane (A‐BM) is developed to replicate the barrier functions of the basement membrane and prevent cell migration. It is demonstrated that the outermost cationic surface charge of nanofilms can effectively inhibit endothelial cell migration and sprouting, allowing for the construction of 3D patterned vascular ...

Visual Navigation of Digital Libraries: Retrieval and Classification of Images in the National Library of Norway's Digitised Book Collection [PDF]

open access: yesarXiv
Digital tools for text analysis have long been essential for the searchability and accessibility of digitised library collections. Recent computer vision advances have introduced similar capabilities for visual materials, with deep learning-based embeddings showing promise for analysing visual heritage. Given that many books feature visuals in addition

CaMKK2 Regulates Macrophage Polarization Induced by Matrix Stiffness: Implications for Shaping the Immune Response in Stiffened Tissues

open access: yesAdvanced Science, EarlyView.
Macrophage phenotypes are influenced by the microenvironment. Matrix stiffness, a key ECM factor, polarizes macrophage toward a pro‐regenerative phenotype in a 3D physiological environment. CaMKK2 selectively regulates stiffness‐induced macrophage polarization, impacting tumor growth and wound healing.

Broadband, Single‐Layered, and Optically Transparent Reflective Phase‐Shifting‐Surface Array for Beam Manipulation and Enhanced Wireless Communications

open access: yesAdvanced Electronic Materials, EarlyView.
A novel optically transparent reflectarray design approach based on multi‐resonant phase‐shifting elements with minimal fine metal line (FML) structures and low‐loss single‐layer cyclic olefin copolymer (COC) substrate is proposed. The design achieves exceptional antenna performance while ensuring high optical transparency, validated through wireless ...

Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

Prognostic significance of six autoantibodies in esophageal squamous cell carcinoma: A prospective multi‐institutional study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
The six autoantibodies (Sui1, p62, RalA, p53, NY‐ESO‐1 and c‐myc) positive group had poor prognosis compared to autoantibody negative group. A panel of autoantibodies against a tumor associated antigen in esophageal cancer patients had an additive effect with SCC‐Ag to detect esophageal SCC even in early stage.

Effects of acute high‐altitude exposure on working memory: A functional near‐infrared spectroscopy study

open access: yesBrain and Behavior, Volume 12, Issue 12, December 2022., 2022
The current study adopted an experimental paradigm of digital span to evaluate acute high‐altitude exposure impairment on working memory. The subjects showed obvious physiological adaptation mechanism at acute altitude. The results of hemodynamic response confirmed the important role of left DLPFC in the process of working memory, revealed abnormal ...
