Development and evaluation of a hydrogenated rosin (β-acryloxyl ethyl) ester–bonded silica stationary phase for high-performance liquid chromatography separation of paclitaxel from yew bark
Rosin-based stationary phase Paclitaxel Retention mechanism Separation Yew-bark extract
2023/12/5
Paclitaxel (PTX) is a complex diterpenoid anticancer drug whose separation from yew biomass poses a significant challenge. In this study, a new stationary phase comprising hydrogenated rosin (β-acrylo...
Molecular simulation and optimization on the microporous structure in carbon molecular sieve membrane for CO2/CH4 separation
Carbon molecular sieve membrane Gas separation Molecular simulation Pore size Structure optimization
2023/6/19
Zigzag-type pore model with a modified structure was proposed to evaluate the effect of micropore structure on the gas separation performance of carbon molecular sieve membranes (CMSM). Molecular simu...
On Abelian Secret Sharing: duality and separation
Access structure Duality Characteristic-dependent information ratio
2019/5/29
Unlike linear secret sharing, very little is known about abelian secret sharing. In this paper, we present two results on abelian secret sharing. First, we show that the information ratio of access st...
Finding Collisions in a Quantum World: Quantum Black-Box Separation of Collision-Resistance and One-Wayness
post-quantum cryptography one-way permutation one-way trapdoor permutation
2018/11/12
Since the celebrated work of Impagliazzo and Rudich (STOC 1989), a number of black-box impossibility results have been established. However, these works only ruled out classical black-box reductions a...
Leakage-Resilient Authenticated Encryption with Misuse in the Leveled Leakage Setting: Definitions, Separation Results, and Constructions
Leakage-resilience authenticated encryption leveled implementations
2018/5/28
We propose definitions and constructions of authenticated encryption (AE) schemes that offer security guarantees even in the presence of side-channel leakages and nonce misuse. This is part of an impo...
Conjugacy Separation Problem in Braids: an Attack on the Original Colored Burau Key Agreement Protocol
Algebraic eraser braid group colored Burau presentation
2018/5/28
In this paper, we consider the conjugacy separation search problem in braid groups. We deeply redesign the algorithm presented in (Myasnikov & Ushakov, 2009) and provide an experimental evidence that ...
Putative Hydrogen Bond to Tyrosine M208 in Photosynthetic Reaction Centers from Rhodobacter capsulatus Significantly Slows Primary Charge Separation
