Ultra‐Fast Non‐Volatile Resistive Switching Devices with Over 512 Distinct and Stable Levels for Memory and Neuromorphic Computing

Advanced Functional Materials, EarlyView.
A materials and device design concept that comprises a self‐assembled ultra‐thin epitaxial ion‐transporting layer, an amorphous oxide overcoat oxygen‐blocking layer, and a partial filament formed during an electroforming step is proposed for low‐current multilevel resistive switching devices.

Mesenchymal Stem Cells‐Derived Extracellular Vesicles Mimetics as Osteoinductive Mediators for Bone Healing

Advanced Functional Materials, EarlyView.
Mesenchymal stem cell‐derived nanoghosts (MSC‐NGs) mimic naturally secreted extracellular vesicles (MSC‐EVs) in structure and physicochemical properties but can be synthesized at more translatable yields. As osteogenic agents, MSC‐NGs demonstrate superior outcomes compared to MSC‐EVs.

A Gym for Cells—Direct Laser Writing of Magnetic Multilayered Micro Actuators for Mechanical Stimulation of Cells

Advanced Functional Materials, EarlyView.
Surface‐attached multilayer micromagnet systems are fabricated by two‐photon crosslinking. The pillar‐shaped micro actuators consist of a soft and flexible surface‐attached cell‐repellent hydrogel layer at the bottom, acting as a hinge and a cell‐adhesive hydrophobic polymer filled with magnetic nanoparticles.

High‐Performance Low‐Emissivity Paints Enabled by N‐Doped Poly(benzodifurandione) (n‐PBDF) for Energy‐Efficient Buildings

Advanced Functional Materials, EarlyView.
This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...

Electrically Induced Negative Differential Resistance States Mediated by Oxygen Octahedra Coupling in Manganites for Neuronal Dynamics

Advanced Functional Materials, EarlyView.
The negative differential resistance is exploited, using a La0.67Sr0.33MnO3 thin film network to demonstrate various neuronal functionalities of the human brain, such as leaky‐integrate‐fire and oscillatory patterns. Transmission electron microscope studies show local modification in oxygen octahedra in the network leads to co‐existing phases ...

Standardized Uptake Value Illuminates Tumor Inflammation and Treatment Response

Clinical Cancer Research, 2021
Abstract Maximum standardized uptake value (SUVmax) on PET imaging is prognostic in cervical cancer. It was recently demonstrated that low pretreatment SUVmax is associated with superior prognosis and is correlated with decreased inflammatory signaling and myeloid-derived cell infiltration into the tumor microenvironment, potentially ...

Prognostic Value of the Standardized Uptake Value in Esophageal Cancer

American Journal of Roentgenology, 2005
On PET, the level of tissue glycolysis can be quantified by the accumulation of fluorine-18-fluorodeoxyglucose expressed as the standardized uptake value (SUV). The aims of this study were to investigate the relation between SUV and the stage of disease and whether SUV can be used to predict resectability and survival in patients with esophageal cancer.

How High Can the Standardized Uptake Value Be?

Clinical Nuclear Medicine, 2002
Positron emission tomography using the glucose analog fluorine-18 fluorodeoxyglucose (FDG PET) provides a unique means for the in vivo noninvasive assessment of metabolism in tumors and other disorders. A high degree of increased metabolism in a lesion is often suggestive of malignancy in the appropriate clinical setting, whereas low levels of FDG ...

Image reconstruction, quantification and standard uptake value [PDF]

, 2000
One of the important characteristics of positron emission tomography (PET) is the ability to quantify metabolic function in vivo. To achieve this goal, radioactivity data (activity per volume) measured by PET is transformed into metabolic parameters of interest by using the simultaneously measured radioactivity in blood and an appropriate physiological
