A fogászatban leggyakrabban használt CAD/CAM rendszerek áttekintése

open access: yes, 2014
A CAD/CAM rendszerek fogászati célú térhódítása az 1980-as évektől kezdődően napjainkban is tart. A számítástechnika nagymértékű fejlődésének és a felhasználható anyagok széles palettájának köszönhetően egyre elterjedtebbek a mindennapi gyakorlatban.

Fabrication of Composite Cathode for All‐Solid‐State Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The design of composite cathodes for all‐solid‐state sodium batteries must address three critical challenges—interfacial side reactions, interfacial delamination, and highly tortuous transport pathways. This work outlines structural and interfacial strategies to optimize ion transport and mechanical stability, enabling durable, and high‐performance ...

Unveiling the High‐Voltage Reactivity and Gas Evolution With Aluminum‐Based Chloride and Oxychloride Catholytes in Solid‐State Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The work examines the electrochemical and interfacial behaviors of crystalline NaAlCl4 and amorphous Na–Al–oxychloride solid electrolytes with NaNi0.5Mn0.5O2 cathodes. Operando gas evolution and ToF‐SIMS analyses highlight that pure chloride solid electrolytes offer greater interfacial stability and safety compared to the oxychloride solid electrolytes

The National Clinical Database Risk Calculator and the 5‐Item Modified Frailty Index Predict the Development of Postoperative Delirium After Surgery for Hepatocellular Carcinoma

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This study demonstrates that combining the NCD Risk Calculator with the mFI‐5 enables more precise stratification of postoperative delirium risk in patients undergoing surgery for HCC. Patients classified as high risk by the combined model showed a markedly higher incidence of delirium than those in the intermediate‐ and low‐risk groups.

Deep Learning‐Assisted Coherent Raman Scattering Microscopy

open access: yesAdvanced Intelligent Discovery, EarlyView.
The analytical capabilities of coherent Raman scattering microscopy are augmented through deep learning integration. This synergistic paradigm improves fundamental performance via denoising, deconvolution, and hyperspectral unmixing. Concurrently, it enhances downstream image analysis including subcellular localization, virtual staining, and clinical ...

Expression and Androgen Regulation of C-Cam Cell Adhesion Molecule Isoforms in Rat Dorsal and Ventral Prostate

open access: yes, 2009
C-CAM is an epithelial cell adhesion molecule with two major splice variants that differ in the length of the cytoplasmic domain. C-CAM1 (long (L)-form) strongly suppresses the tumorigenicity of human prostate carcinoma cells. In contrast, C-CAM2 (short (
