Injectable Dual‐Network Hydrogel System for Osteochondral Repair Combining Immunomodulation, Mechanical Adaptability, and Enhanced Tissue Integration

open access: yesAdvanced Functional Materials, EarlyView.
A UV‐triggered injectable dual‐network hydrogel is reported as the first application of bletilla striata polysaccharide (BSP) in osteochondral repair. By integrating methacrylamide‐modified BSP and nitrobenzaldehyde‐functionalized hyaluronic acid, the system achieves immunomodulation, mechanical reinforcement, and dynamic tissue adhesion, thereby ...

Fast Mojette Transform for Discrete Tomography

open access: yes, 2010
A new algorithm for reconstructing a two dimensional object from a set of one dimensional projected views is presented that is both computationally exact and experimentally practical. The algorithm has a computational complexity of O(n log2 n) with n = N^

Dense Nanofibrillar Collagen–Silica Hybrids with High Strength and ECM‐Mimetic Tissue Integration

open access: yesAdvanced Functional Materials, EarlyView.
Dense nanofibrillar collagen–silica hybrids are engineered by synchronizing collagen fibrillogenesis with silica condensation, producing printable scaffolds that unexpectedly approach native extracellular matrix organization and strength. These cell‐free constructs guide endogenous cell‐infiltration, enable localized matrix remodeling, and integrate ...

Who is Patrick? – Answers from the Saint Patrick's Confessio HyperStack. Supporting Digital Humanities, Copenhagen 17 - 18 November 2011, Conference Proceedings [PDF]

open access: yes, 2013
Not everyone realizes that there are two Latin works, still surviving, that can definitely be attributed to Saint Patrick’s own authorship. On 14th September 2011 the Royal Irish Academy published his writings in a freely accessible form on line, both in

Imaging of Biphoton States: Fundamentals and Applications

open access: yesAdvanced Functional Materials, EarlyView.
Quantum states of two photons exhibit a rich polarization and spatial structure, which provides a fundamental resource of strongly correlated and entangled states. This review analyzes the physics of these intriguing properties and explores the various techniques and technologies available to measure them, including the state of the art of their ...

Recording and Reconstructing the Sacred Landscapes of Sicilian Naxos

open access: yesOpen Archaeology, 2019
In recent years, an on-going project investigating the urban landscape of Naxos has surveyed and produced several new digital reconstructions of the settlement’s simple non-peripteral temples, most with highly decorative roofs.

The curvelet transform for image denoising [PDF]

open access: yes, 2002
We describe approximate digital implementations of two new mathematical transforms, namely, the ridgelet transform and the curvelet transform. Our implementations offer exact reconstruction, stability against perturbations, ease of implementation, and ...

From the archaeological reality to the digital reconstruction: an architectural drawing challenge

open access: yesDisegnare con, 2017
The archaeological patrimony in the Mediterranean area is one of the most intense manifestation of the will of the many societies populating this area since ancient times. It is a complex and articulated Cultural Heritage presenting difficult puzzles and
