Regular and almost universal hashing: an efficient implementation [PDF]

Software: Practice and Experience 47 (10), 2017, 2016
Random hashing can provide guarantees regarding the performance of data structures such as hash tables---even in an adversarial setting. Many existing families of hash functions are universal: given two data objects, the probability that they have the same hash value is low given that we pick hash functions at random.

3D In Vitro Glioma‐Neuron‐Astrocyte Biomimetic Composites Recapitulate Key Molecular Mechanisms Linked to Glioblastoma Multiforme Pathophysiology

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

Regioselective and Anisotropic Multi‐Patching of Small Microparticles via a Polymer Brush‐Assisted Microcontact Printing (µCP)

Advanced Functional Materials, EarlyView.
A method to fabricate anisotropic SiO2 patchy microspheres is presented using a modified microcontact printing technique. This involves a PDMS elastomer stamp with grooved surface topography, creating a confined environment for the microspheres.

Multiple Code Hashing for Efficient Image Retrieval [PDF]

arXiv, 2020
Due to its low storage cost and fast query speed, hashing has been widely used in large-scale image retrieval tasks. Hash bucket search returns data points within a given Hamming radius to each query, which can enable search at a constant or sub-linear time cost.

Understanding the Temperature Conditions for Controlled Splicing Between Silica and Fluoride Fibers

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
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.

Hyperdimensional Hashing: A Robust and Efficient Dynamic Hash Table [PDF]

arXiv, 2022
Most cloud services and distributed applications rely on hashing algorithms that allow dynamic scaling of a robust and efficient hash table. Examples include AWS, Google Cloud and BitTorrent. Consistent and rendezvous hashing are algorithms that minimize key remapping as the hash table resizes.

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 ...

3D Printed Mesh Geometry Modulates Immune Response and Interface Biology in Mouse and Sheep Model: Implications for Pelvic Floor Surgery

Advanced Science, Volume 12, Issue 11, March 20, 2025.
Pelvic organ prolapse (POP) is a significant health challenge for women, especially with the lack of optimal surgical options post‐withdrawal of synthetic transvaginal meshes. The study pioneers degradable melt electrowrite vaginal implants with precise 22.5° angles and specific porosity. These configurations significantly influence macrophage behavior
