CAMD MINLP model Reaction solvent Group contribution Inertness
2023/6/19
Solvents have been widely used in process manufacturing industries. When involved in liquid-phase organic synthesis reactions, solvents can reduce the activation energy of reactions between the reacta...
郭新闻论文成果：The template-assisted zinc ion incorporation in SAPO-34 and the enhanced ethylene selectivity in MTO reaction
SAPO-34 Metal modification MTO Product selectivity Ethylene
2023/3/6
The SAPO-34 catalyst was fine-tuned with zinc cations through a straightforward template-assisted ion incorporation (TII) process, without the necessary template pre-removal and the preparation of NH4...
A Reaction Attack against Cryptosystems based on LRPC Codes
Rank-based cryptography Code-based cryptography LRPC cryptosystems
2019/7/22
Rank metric is a very promising research direction for code-based cryptography. In fact, thanks to the high complexity of generic decoding attacks against codes in this metric, it is possible to easil...
We propose a new reaction attack on the public-key cryptosystem LEDApkc. The adversary uses the decoding failure rate (DFR) analysis to learn information about the secret masking matrix Q.
A Reaction Attack on the QC-LDPC McEliece Cryptosystem
QC-LDPC McEliece cryptosystem reaction attack soft-decision decoding
2017/6/2
Guo et al. recently presented a reaction attack against the QC-MDPC McEliece cryptosystem. Their attack is based on the observation that when a bit-flipping decoding algorithm is used in the QC-MDPC M...
Screening of BCL-2 associated X protein gene polymorphism associated with scrotal hernia in domesticated swine using polymerase chain reaction-restriction fragment length polymorphism
BAX Gene Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) Screening
2017/3/9
This study was conducted to screen scrotal hernia in domesticated swine from selected breeders in the Philippines. This defect is associated with a cytosine to thymine mutation in the BCL-2 associated...
