Effects of Crushed Oyster Shell on Strength and Durability of Marine Concrete Containing Fly Ash and Blastfurnace Slag

Medžiagotyra, 2019
A large quantity of oyster shell is generated every year in coastal regions. Instead of being dumped as waste, after crushing or grinding, oyster shell may be recycled for use in concrete. Herein, the use of crushed oyster shell (COS) in conjunction with

A directed isoperimetric inequality with application to Bregman near neighbor lower bounds

, 2015
Bregman divergences $D_\phi$ are a class of divergences parametrized by a convex function $\phi$ and include well known distance functions like $\ell_2^2$ and the Kullback-Leibler divergence.

Creativity and destructiveness in art and psychoanalysis [PDF]

, 2015
This paper focuses on the creativity of the patient in analysis and compares it to that of the artist. Taking artists’ descriptions of their practices as its starting point, the paper suggests that the relationship between patient and analyst parallels ...

Robust Polymer Hydrogels Improve Electric‐Fish‐Inspired Batteries

Advanced Functional Materials, EarlyView.
ABSTRACT Electric‐fish‐inspired hydrogel batteries based on ion‐concentration gradients offer an attractive route to soft power sources; however, the poor mechanical properties of existing hydrogels limit device assembly and performance. Here, we report poly(ethylene glycol) methyl ether acrylate hydrogels that enable ion‐gradient batteries composed of

Improved Conditional Cube Attacks on Ascon AEADs in Nonce-Respecting Settings

IACR Transactions on Symmetric Cryptology
The best-known distinguisher on 7-round Ascon-128 and Ascon-128a AEAD uses a 60-dimensional cube where the nonce bits are set to be equal in the third and fourth rows of the Ascon state during initialization (Rohit et al. ToSC 2021/1).

Polypropylene fibres within concrete with regard to heat induced spalling and reduction in compressive strength [PDF]

, 2008
The paper examines the effect of various polypropylene fibre additions (Types 1 and 2 and different fibre volumes) to concrete with regard to explosive spalling when subject to high temperatures similar to that experienced in building or tunnel fires ...

Algorithmic Design of Disordered Networks With Arbitrary Coordination: Application to Biophotonics

Advanced Functional Materials, EarlyView.
Predictive Design of Disordered Networks: Disordered network‐like morphologies are abundant in nature, from cytoskeletal networks to bone structures and chalcogenide glasses. These structures are naturally hard to characterize. A new algorithmic tool extends the established Wooten–Weaire–Winer (WWW) algorithm to valencies above 4.

Cube Attacks with Elimination Strategy: Key Recovery Attacks on Trivium

IACR Transactions on Symmetric Cryptology
In this paper, we present a novel framework for cube attacks named cube attacks with elimination strategy. The core idea is to find specific key conditions and cubes such that their superpolies under these key conditions can be efficiently computed.

Comparison of Cube Attacks Over Different Vector Spaces [PDF]

, 2015
We generalise the cube attack of Dinur and Shamir and the similar AIDA attack of Vielhaber to a more general higher order differentiation attack, by summing over an arbitrary subspace of the space of initialisation vectors. The Moebius transform can be used for efficiently examining all the subspaces of a big space, similar to the method used by Fouque
