Advanced Functional Materials, EarlyView.Glioblastoma multiforme is the most devastating and incurable brain tumor. To better study this disease, a 3D model is developed using a hyaluronic acid‐based hydrogel combined with a multicellular approach. This model recapitulates in vivo brain stiffness, cell‐extracellular matrix and cell‐cell interactions and the tumor's hijacking function with the

Towards roadmap to implement blockchain in healthcare systems based on a maturity model
Journal of Software: Evolution and Process, Volume 34, Issue 12, December 2022., 2022 This study presents a roadmap to develop a maturity model for blockchain in healthcare (MMBH) based on critical barriers (CBs), critical success factors (CSFs), and the best practices for blockchain implementation in healthcare systems. As a first step to develop the MMBH, in this paper, we present the initial results of a systematic literature review (

Indifferentiable hash functions in the standard model
IET Information Security, 2021 Indifferentiability of iterated hash functions is seen as evidence that there are no structural flaws in the iteration structure of the algorithm. However, it is often overlooked that such considerations only hold in the random oracle model and do not ...

Understanding the Temperature Conditions for Controlled Splicing Between Silica and Fluoride Fibers
Advanced Photonics Research, EarlyView.Thermal splicing conditions are investigated between silica and ZrF4 fibers, focusing on mechanical strength. A fiber Bragg grating characterises the thermal profile in the filament splicer's hot zone. Results indicate a narrow temperature window for strong joints.

High Performance and Low Power Hardware Implementation for Cryptographic Hash Functions
International Journal of Distributed Sensor Networks, 2014 Since hash functions are cryptography's most widely used primitives, efficient hardware implementation of hash functions is of critical importance. The proposed high performance hardware implementation of the hash functions used sponge construction which

Annales UMCS, Informatica, 2012 In this paper we describe a family of highly parameterized hash functions. This parameterization results in great flexibility between performance and security of the algorithm. The three basic functions, HaF-256, HaF-512 and HaF-1024 constitute this hash function family. Lengths of message digests are 256, 512 and 1024 bits respectively.

Electro‐Thermal Response of Thin Film Heaters Based on Embedded Periodic Metallic Mesh
Advanced Theory and Simulations, EarlyView.“This study systematically investigates the effect of periodic metallic mesh topology on electrical and electro‐thermal behaviours of thin thermal heaters. The derived closed‐form expressions capture the dependence of sheet resistance on design parameters, providing a crucial tool for rapidly exploring a vast design space and accelerating design and ...

Solar RRL, Volume 6, Issue 12, December 2022., 2022 A combination strategy of using KBr modification and laser processing is demonstrated to prepare and optimize the SnO2 film as the electron transport layer for rigid and flexible perovskite solar cells (PSCs). This strategy successfully improves the power conversion efficiency and durability of the rigid and flexible PSCs.
