Optimization of 3D‐Printed Structured Packings—Current State and Future Developments
Chemie Ingenieur Technik, EarlyView.This paper gives an overview about structured packing development for distillation, surveying heuristic development cycles, computational fluid dynamics simulations, and additive manufacturing techniques. The emerging application of shape optimization to improve packings is emphasized, and its benefits, impact, and limitations are discussed.

Building PRFs from TPRPs: Beyond the Block and the Tweak Length Bounds
IACR Transactions on Symmetric CryptologyA secure n-bit tweakable block cipher (TBC) using t-bit tweaks can be modeled as a tweakable uniform random permutation, where each tweak defines an independent random n-bit permutation.

IACR Transactions on Symmetric Cryptology, 2017 CAESAR has caused a heated discussion regarding the merits of one-pass encryption and online ciphers. The latter is a keyed, length preserving function which outputs ciphertext blocks as soon as the respective plaintext block is available as input.

Finding efficient distinguishers for cryptographic mappings, with an application to the block cipher TEA [PDF]
, 2003 Congress on Evolutionary Computation. 8-12 December 2003A simple way of creating new and efficient distinguishers for cryptographic primitives such as block ciphers or hash functions is introduced. This technique is then successfully applied over reduced

Visualizing Specific Tubulin Isotypes and Pathogenic Variants in Cellular Microtubule Arrays
Cytoskeleton, EarlyView.ABSTRACT Eukaryotic cells depend on dynamic microtubule arrays to execute a wide range of functions vital for life. These microtubule filaments are formed through the polymerization of α/β‐tubulin proteins, which can be generated from numerous tubulin genes, or isotypes.

Environmental Policy and Governance, EarlyView.ABSTRACT The role of civil society organizations (CSOs) in addressing climate change is acknowledged, but engagement with questions of voice remains limited, especially in the Global South. Addressing this, this paper zooms in on (International) nongovernmental organizations ((I)NGOs) and their collaborations with domestic CSOs in the Global South on ...

Key‐dependent side‐channel cube attack on CRAFT
ETRI Journal, 2021 CRAFT is a tweakable block cipher introduced in 2019 that aims to provide strong protection against differential fault analysis. In this paper, we show that CRAFT is vulnerable to side‐channel cube attacks.

A Domain Extender for the Ideal Cipher [PDF]
, 2009 We describe the first domain extender for ideal ciphers, {\sl i.e.} we show a construction that is indifferentiable from a $2n$-bit ideal cipher, given a $n$-bit ideal cipher.

Cryptanalysis of IAR-CTR and IAR-CFB and a fixing method
CybersecurityWe present practical attacks on IAR-CTR and IAR-CFB, AE modes proposed by Hwang and Gope to offer both privacy and authenticity in a single pass. Then we use the idea of iCOFB, which is originally defined with a tweakable random function, to fix the IAR ...

Food Biomacromolecules, EarlyView.Agar xerogel was used to immobilize cellulase. Properties of partially purified cellulase from Aspergillus foetidus and commercial cellulase were compared after immobilization. Abstract This research study is a comparative study of the characteristics of partially purified cellulase produced from Aspergillus foetidus through solid‐state fermentation ...
